Many surgeons have demonstrated the validity of sternocleidomastoid muscle flaps for the reconstruction of head and neck tumors. We present a case in which we used an island sternocleidomastoid muscle flap to reconstruct a cheek depression after excision of a malignant parotid tumor. A 44-year-old woman presented with a right malignant parotid tumor. We performed total resection of the parotid gland and facial nerve with the sural nerve and reconstructed the facial nerve and cheek depression with an island sternocleidomastoid muscle flap. The sternal head of the right sternocleidomastoid muscle was cut at the cranial and caudal segments to elevate it as an island flap. We used the superior thyroid artery as the sole pedicle for the island muscle flap. At 1 year and 3 months after the operation, the mimic muscles had gradually recovered and progressed without complications such as Frey syndrome, cervical motor dysfunction, or concave deformation of the neck and cheeks.

There are currently no guidelines for the postoperative wound management of the hard-palate donor site in cases involving mucosal harvesting. This study describes our experiences with the use of an artificial dermis for early epithelialization and transparent plate fixation in cases involving hard-palate mucosal harvesting.

A transparent palatal plate was custom-fabricated using a thermoplastic resin board. After mucosal harvesting, an alginic acid-containing wound dressing (Sorbsan) was applied to the donor site, which was then covered with the plate. After confirming hemostasis, the dressing was changed to artificial dermis a few days later, and the plate was fixed to the artificial dermis. The size of the mucosal defect ranged from 8×25 to 20×40 mm.

Plate fixation was adequate, with no postoperative slippage or infection of the artificial dermis. There was no pain at the harvest site, but a slight sense of incongruity during eating was reported. Although the fabrication and application of the palatal plate required extra steps before and after harvesting, the combination of the artificial dermis and palatal plate was found to be very useful for protecting the mucosal harvest site, and resulted in decreased pain and earlier epithelialization.

The combination of artificial dermis and a transparent palatal plate for wound management at the hard-palate mucosal donor site resolved some of the limitations of conventional methods.

The combination of artificial dermis and a transparent palatal plate for wound management at the hard-palate mucosal donor site resolved some of the limitations of conventional methods.Traditional orthognathic surgery has long been performed after presurgical orthodontic treatment. Despite some concerns, the surgery-first orthognathic approach (SFOA) or surgery-first approach (SFA) without presurgical orthodontic treatment has gradually gained popularity. In recent years, several articles dealing with the concepts of the SFA have been published worldwide. However, the SFA has not yet been standardized, and many surgeons use slightly different protocols and concepts. This review article discusses the beginning and evolution of the SFA and its current concepts, including some opinions based on the authors’ clinical experiences over the last 15 years. According to recent investigations, the SFA could be applied effectively in several situations including class III malocclusion, class II malocclusion, and facial asymmetry. However, debate on the SFA continues and many issues remain to be resolved. This review article addresses the current issues regarding the SFOA, including its advantages and disadvantages, as well as its indications and contraindications. The authors summarize various aspects of the SFA and expect that this review article will help surgeons and orthodontists better understand the current status of the SFA.Robot-assisted nipple-sparing mastectomy with immediate reconstruction is currently performed in an attempt to seek smaller and indistinct incisions. Robotic surgery system has been evolving under the concept of minimal invasive technique which is a recent trend in surgery. One of the latest version is the da Vinci SP Surgical System (Intuitive Surgical). In this report, we will share our experiences. Two patients underwent robot-assisted nipple-sparing mastectomy, each followed by immediate robot-assisted expander insertion and prepectoral direct-to-implant breast reconstruction, respectively. There was no open conversion or major postoperative complication. One patient experienced mild infection, which was resolved by intravenous antibiotic treatment. Simple docking process, multi-joint instruments, and third-arm functionality are among the new surgical system’s advantages. The present cases suggest that robot-assisted nipple-sparing mastectomy with immediate reconstruction using the da Vinci SP Surgical System is feasible and safe. The promising features and potential application of da Vinci SP in breast reconstruction need further study.Breast implant insertion is one of the most commonly used methods for breast reconstruction after total mastectomy. However, infection is a common postoperative complication of implant insertion. In most cases, these infections can be managed with antibiotics and supportive therapy. However, severe septic conditions, such as toxic shock syndrome (TSS), can sometimes occur. TSS is an extremely rare but life-threatening complication, for which early diagnosis and proper management play a crucial role in determining patients’ outcome. Although only 16 cases of TSS after breast implant insertion have been reported in the literature, most of those cases involved a serious clinical course. The reason for the seriousness of the clinical course of TSS in these cases is that the initial impression and presentation of these patients are nonspecific, and patients can easily be misdiagnosed as having a simple upper respiratory infection, causing the underlying condition to be neglected. Herein, we present two patients who were diagnosed with TSS after receiving breast reconstruction surgery via a silicone implant after total mastectomy. Both patients were misdiagnosed at the initial examination since they showed no local infectious signs on the postoperative wound.Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome can be treated through numerous surgical and nonsurgical methods. We present a surgical technique in which a neovagina was reconstructed and shaped by a vaginal expander with acellular porcine dermal matrix (XCM Biologic Tissue Matrix) and mucosal interposition using microfragments harvested from the hymen. In our case, we found this procedure to be safe and effective, resulting in satisfactory sexual function and good cosmetic results, without donor site morbidity. To our best knowledge, this tissue-engineered biomaterial has never been used for vaginal reconstruction before.Women attach great importance to the presence of a three-dimensional nipple upon completion of the breast reconstruction process. To meet patients’ expectations, nipple-areolar complex reconstruction should achieve symmetry in position, size, shape, texture, and color, as well as minimizing donor-site morbidity. However, it is well known that regardless of the reconstructive technique, loss of nipple projection can be reasonably expected. We developed and evaluated a quick, simple, and innovative technique using injectable Integra Flowable Wound Matrix to increase nipple projection after reconstruction. Twenty breast cancer patients who underwent nipple reconstruction resulting in unsatisfactory projection were enrolled in our retrospective study. Nipple projection was measured at the time of surgery and after 6 and 12 months. A visual analogue scale was used to assess patients’ satisfaction. Our technique yielded reliable results in terms of the long-lasting maintenance of nipple projection. This method is high-priced, but cost-effective, since one kit may suffice for three patients. Furthermore, our patients were very appreciative of this technique as a single-step, minimally invasive, painless procedure with no reported necessity of re-intervention.The umbilicus is an important aesthetic component of the abdomen; therefore, its absence is both cosmetically and psychologically distressing to the patient. However, loss of the umbilicus during abdominal surgical procedures is often unavoidable. Umbilical reconstruction is aimed at obtaining a natural, three-dimensional appearance. We propose a simple method for immediate umbilical reconstruction with good long-term results. This technique was used successfully on a patient who underwent tumor excision. A 49-year-old woman presented with a large mass, measuring 5.8×4.0 cm, on her umbilicus. The mass, an epidermal cyst, developed after laparoscopic uterine myomectomy 5 years earlier. Complete excision of the mass resulted in a large defect, and immediate umbilical reconstruction was planned. Our procedure involved apposing and anchoring two opposing flaps onto the abdominal wall, so that the umbilicus would retain its depth over a long period of time. Negative-pressure wound therapy was applied for 72 hours as a mild compressive dressing. No complications were encountered. The healing process was uneventful and the aesthetic outcome was pleasing; a natural-appearing navel was created. The patient was satisfied with the end result. This technique provides a permanent and sufficient depression for the umbilicus.

In recent years, implant-based breast reconstruction has been performed because of its simplicity, short operation time, and rapid recovery of patients. Several studies have reported treatment methods for implant surgery-related infection, which is a serious complication. The aim of this study was to introduce our strategy for salvaging infected implants and to evaluate its effectiveness.

The authors performed a retrospective study of 145 cases from 132 patients who underwent implant-based breast reconstruction from January 2012 to December 2018. Empirical antibiotics were immediately administered to patients with suspected infections. The patients then underwent salvage treatment including appropriate antibiotics, ultrasonography-guided aspiration, debridement, antibiotic lavage, and implant exchange through a multidisciplinary approach. Patient demographics, operative data, duration until drain removal, adjuvant treatment, and complications were analyzed.

The total infection rate was 5.5% (8/145). A lth the necessary departments are required. Through a multidisciplinary approach and proactive early management, swift and appropriate salvage should be performed.

In lower lateral cartilage (LLC) surgery, cephalic trimming poses risks for the collapse of the internal and external nasal valves, pinched nose, and drooping deformity. The cephalic lateral crural advancement (CLCA) technique presented herein was aimed at using a flap to increase nasal tip rotation and support the lateral crus, in addition to the internal and external nasal valves, by avoiding grafts without performing excision.

This study included 32 patients (18 female and 14 male) and the follow-up period for patients having undergone primer open rhinoplasty was 12 months. The LLC was elevated from the vestibular skin using the CLCA flap. A cephalic incision was performed without cephalic trimming. Two independent flaps were formed while preserving the scroll ligament complex. The CLCA flap was advanced onto the lower lateral crus while leaving the scroll area intact. The obtained data were analyzed retrospectively.

The mean age of the patients was 31.6 years (range, 20-51 years). The Rhinoplasty Outcome Examination scores after 12 months varied from 90 to100 points, and 93% of patients reported perfect satisfaction. At a 1-year follow-up, the patients’ nasal patency (visual analogue scale) rose from 4.56±1.53 (out of 10) to 9.0±0.65 (P<0.001).

The CLCA flap led to better nasal tip definition by protecting the scroll area, increasing tip rotation, and supporting the internal and external nasal valves without cephalic excision.

The CLCA flap led to better nasal tip definition by protecting the scroll area, increasing tip rotation, and supporting the internal and external nasal valves without cephalic excision.Scars vary from mature linear scars to abnormal excessive scars such as hypertrophic scars and keloid scars. Keloid scars are fibro-proliferative disease entities that reflect an abnormal process of wound healing. They can cause pain, itching, stiffness, and psychological distress, all of which can affect quality of life. Various treatment options have been advocated as ways to prevent and treat keloid scars. These include noninvasive treatments such as use of silicone gel sheeting and compression therapy, and invasive treatments such as intralesional corticosteroid injections, surgery, and radiotherapy. Novel treatments include chemotherapy, immunotherapy, and anti-inflammatory therapies. Unfortunately, keloids continue to pose a significant challenge due to the lack of efficacious treatments. Therefore, clinicians should be familiar with various therapeutic options and apply the most suitable treatment plan for patients. In this review, we introduce the current therapeutic options for the management of keloid scars.Although randomized control trials about endovascular treatment (EVT) of emergent large vessel occlusion (LVO) have demonstrated the success of mechanical thrombectomy as the choice of treatment, a wide range of caveats remain unaddressed. Asian patients were rarely included in the trials, thereby raising the question of whether the treatment could be generalized. In addition, there remains a concern on the feasibility of the method with respect to its application against intracranial atherosclerosis (ICAS)-related LVO, frequently observed in the Asian population. It is important to include evidence on ICAS LVO from Asian countries in the future for a comprehensive understanding of LVO etiology. Besides the issues with EVT, prognostic concerns in diabetes patients, acute kidney injury following EVT, neuroprotective management against reperfusion injury, and other peri-EVT issues should be considered in clinical practice. In the current article, we present an in-depth review of the literature that revises information pertaining to such concerns.With advancing analytical methods for gut microbes, many studies have been conducted, revealing that gut microbes cause various diseases, including gastrointestinal and non-gastrointestinal diseases. Accordingly, studies have been actively conducted to analyze the effects on the prevention and treatment of these diseases through changes in intestinal microbes and control of dysbiosis. Fecal microbiota transplantation (FMT) is an effort and is currently being applied to Clostridioides difficile treatment in Korea. Many studies have demonstrated the application of FMT in inflammatory bowel disease, irritable bowel syndrome, non-alcoholic fatty liver disease, metabolic syndrome, obesity, and diabetes. With further studies and accumulation of evidence, FMT could help treat presently untreatable diseases in clinical practice.We introduce MosaicExplorerJ, an ImageJ macro to stitch 3D tiles from terabyte-size microscopy datasets organized on a regular 2D grid. As opposed to existing software, stitching does not require any prior information on the actual positions of the tiles, or conversion of raw TIFF images to a multi-resolution format for interactive exploration and fast processing. MosaicExplorerJ was specifically designed to process lightsheet microscopy datasets from optically cleared samples. It can handle multiple fluorescence channels, dual-sided lightsheet illumination and dual-sided camera detection.Vitiligo is a disease of mysterious origins in the context of its occurrence and pathogenesis. The autoinflammatory theory is perhaps the most widely accepted theory that discusses the occurrence of Vitiligo. The theory elaborates the clinical association of vitiligo with autoimmune disorders such as Psoriasis, Multiple Sclerosis and Rheumatoid Arthritis and Diabetes. In the present work, we discuss the comprehensive set of differentially co-expressed genes involved in the crosstalk events between Vitiligo and associated autoimmune disorders (Psoriasis, Multiple Sclerosis and Rheumatoid Arthritis). We progress our previous tool, Vitiligo Information Resource (VIRdb), and incorporate into it a compendium of Vitiligo-related multi-omics datasets and present it as VIRdb 2.0. It is available as a web-resource consisting of statistically sound and manually curated information. VIRdb 2.0 is an integrative database as its datasets are connected to KEGG, STRING, GeneCards, SwissProt, NPASS. Through the present study, we communicate the major updates and expansions in the VIRdb and deliver the new version as VIRdb 2.0. VIRdb 2.0 offers the maximum user interactivity along with ease of navigation. We envision that VIRdb 2.0 will be pertinent for the researchers and clinicians engaged in drug development for vitiligo.Wound healing is a complex and critical process, which includes three stages inflammation, proliferation, and remodeling. The epidermal cells are precisely regulated in this process. On one hand, keratinocytes around the wound edge migrate and proliferate to form a new basement membrane to cover the wound. On the other hand, the epidermal stem cells are activated with the proliferation and differentiation being enhanced, and the terminal differentiation and apoptosis being inhibited; and together with keratinocytes, epidermal stem cells promote the process of re-epithelialization under the regulation of various factors. In the epidermis, there is a group of resident T cell subsets, dendritic epidermal lymphocytes (DETCs) that play a key role in protecting the function of epidermal tissue. DETCs are activated after recognizing unknown antigens, the activated DETCs secret cytokines such as insulin-like growth factor Ⅰ, keratinocyte growth factor-1/2, granulocyte-macrophage colony stimulating factor, interferon-γ, and transforming growth factor-β, which promote epidermal homeostasis and re-epithelialization by regulating the dynamic balance among keratinocytes migration, proliferation, and apoptosis, and the differentiation of epidermal stem cells around the wound edge. This article discusses the biological characteristics of DETCs and their roles in the maintenance of epidermal homeostasis and wound healing.Mechanical power is the power that the ventilator transmits to the respirator for lung ventilation. In recent years, some researchers have suggested that mechanical power may be a good indicator for assessing ventilator-induced lung injury in general, which can be used for guiding the best mechanical ventilation strategy. While introducing the definition and calculation method of mechanical power, this paper focuses on the association and potential mechanism of mechanical power with ventilator-induced lung injury, which aims to provide a new perspective and research direction for clinical understanding of ventilator-induced lung injury.Objective To explore the clinical effects of autologous skin paste in repairing medium-thickness skin donor site wounds. Methods The prospective randomized controlled research method was applied. From October 2018 to December 2019, 18 patients with flame burn or hydrothermal scald, conforming to the inclusion criteria were admitted to Jinhua Hospital Affiliated to Zhejiang University School of Medicine, including 15 males and 3 females, aged (45±6) years. The wounds were repaired with medium-thickness skin grafts from thigh, and the wound area was (121±33) cm2 after medium-thickness skin grafting. The medium-thickness skin donor site wound in each patient was divided into 2 wounds in equal area and allocated into autologous skin paste group and conventional treatment group by flipping a coin, with 18 wounds in each group. The wounds in autologous skin paste group were repaired with skin paste prepared with remaining skin fragments after autologous medium-thickness skin grafting, and the wounds in conventionalia, with a good clinical effect.Objective To estimate the safety and efficacy of remimazolam tosilate used for moderate-to-deep sedation in fiberoptic bronchoscopy with its 50% effective dosage (ED50) and 95% effective dosage (ED95) calculated. Methods A total of 50 patients aged from 18 to 65 years and classified as Class Ⅰ or Ⅱ according to the American Society of Anesthesiologists (ASA) Classification who underwent fiberoptic bronchoscopy in Hainan Cancer Hospital from April to August of 2020 were included in this study. For each patient, bronchoscopy was only started when the eyelash reflex disappeared and MOAA/S score was less then 1 after a trial dose of remimazolam tosilate combined with 0.1 μg/kg sufentanil was intravenously given. The dosage of remimazolam tosilate for the first patient was 0.18 mg/kg, based on which the dosages for the following patients were increased or decreased by 1∶1 times for one another, forming an equal ratio sequence. A maintenance dose of remimazolam tosilate was pumped intravenously in a rate of 1 mg/(kg·h) during the bronchoscopic examination and treatment. The result of the sequential trial, the time to achieve proper sedation, the analepsia time and the adverse effects were recorded. Results All the 50 patients went through bronchoscopy completely. The regression function of the sequential trial was Y=12.589+16.593X, the ED50 and the ED95 of remimazolam tosilate were 0.174 (95%CI 0.162-0.186) mg/kg and 0.219 (95%CI 0.199-0.312) mg/kg, respectively. The time to achieve proper sedation was (50±11) s and the mean analepsia time after the use of flumazenil was (56±16) s. There was one patient with respiratory inhibition, one with headache and dizziness, one with fatigue among the 50 patients. Conclusions The strategy of moderate-to-deep sedation based on remimazolam tosilate is safe and effective in bronchoscopic examination and treatment. When combined with 0.1 μg/kg sufentanil, the ED50 and the ED95 of remimazolam tosilate are 0.174 mg/kg and 0.219 mg/kg, respectively.Objective Explore the feasibility of fecal gene methylation for screening gastric cancer and its relationship with clinical characteristics of gastric cancer patients. Methods One hundred and fifty-six stool samples of patients in general surgery or digestive department of the First Affiliated Hospital of Soochow University from August 2018 to December 2019 were collected, detailed clinical information of gastric cancer patients were recorded. All patients and normal controls were divided into two sets including train sets (n=52)and test sets (n=104). Stool DNA was extracted for detection of methylation (SDC2, SFRP2, RASSF2 and TERT). Meanwhile, hemoglobin in stool samples were detected by immunoassays. A logistic regression model was built to analyze the sensitivity and specificity of single fecal DNA biomarker in detecting gastric cancer by Ct values of each stool-based DNA biomarker; Based on Akaike information criterion (AIC), the gastric cancer early screening model was constructed with each biomarker and the combinations, and evaluate the performance of the model in the test sets. Results The accuracy of each stool biomarkers and their ranks were showed as SDC2(71.2%)>TERT(67.3%)=RASSF2(67.3%)>Hb(63.5%)>SFRP2(61.5%). By stepwise regression analysis, a combination composed of the methylation of SDC2 and TERT, fecal occult blood testing was well-behaved in the screening of gastric cancer.This combination showed a sensitivity of 66.7% for gastric cancer in train sets and test sets at the specificity of 78.9%. In different stages and parts of gastric cancer samples, the combination of this marker has the highest sensitivity in stage I gastric cancer(78.6%) and gastric body cancer(75.0%). Conclusion The methylation of SDC2, SFRP2, TERT, RASSF2 has higher accuracy rate in the screening of gastric cancer, which is a potential fecal biomarker of gastric cancer.Objectives To delineate clinico-pathological features, treatment and outcome of skeletal muscle single-organ vasculitis (SM-SOV). Methods The clinico-pathological characteristic of SM-SOV cases treated over 3 years in China-Japan Friendship Hospital were retrospectively analyzed and the data were compared with the cases from the literature. Results Five patients (2 women and 3 men) with a median age of 36 years were included in this study. The main clinical manifestations were lower limb myalgia (5/5) and fever (1/5). The most frequent laboratory findings included high erythrocyte sedimentation rate (5/5), high C reactive protein (5/5) and leukocytosis (1/5). No elevated creatine kinase (CK) was found in these cases. Four patients received electromyogram examination and none of them showed myogenic injury. On MRI, hyperintense signals in T2 weighted image (T2WI) and/or short TI inversion recovery (STIR) and normal unenhanced T1 weighted image (T1WI) of one or several leg muscles was founded in all 5 patients. All muscle specimens showed nongranulomatous vasculitis without myonecrosis affecting small sized artery (5/5) in perimysia (75.0%, 3/4) or both perimysia and fascia (25.0%, 1/4). Corticosteroids (5/5) and immunosuppressants (5/5) were the main agents prescribed. With a median follow-up of 24 months, sustained remission was observed in 3 patients, relapses occurred in 2 patients. Conclusion SM-SOV should be considered for patients with lower limb myalgia, high inflammatory markers and normal/low CK level. The diagnosis of SM-SOV should be applied when there are both histologic evidence of vasculitis and a minimum of 6 months of follow-up surveillance without evidences suggesting extra-muscular involvement. Corticosteroid combined with immunosuppressant is effective.Objective To investigate the expression of cell proliferating nuclear antigen (Ki67) and cytokeratin 19 (Ck19) in hepatocellular carcinoma (HCC), and correlation with the clinicopathological features and apparent diffusion coefficient (ADC) value of hepatocellular carcinoma. Methods The data of 203 newly diagnosed HCC patients in the Affiliated Cancer Hospital of Zhengzhou University from January 2014 to October 2019 were retrospectively collected, and the expression of Ki67 and Ck19 and ADC values in all patients were analyzed. The relationship between Ki67 and Ck19 and the clinical pathological characteristics of the patient, and calculate the difference and correlation with the ADC value was analyzed. Results There were statistically significant differences in tumor vascular tumor thrombus, alpha-fetoprotein (AFP), postoperative tumor recurrence, lymph node metastasis, and HCC differentiation between Ki67 positive and negative groups (χ²=5.156, 12.741, 29.925, 3.963, 77.408, all P less then 0.05),and negatively correlated with ADC value (r=-0.214, P=0.002). The average ADC value of HCC in the low Ki67 group was significantly higher than that of the high Ki67 group (1 089±280 vs 1 009±212, P less then 0.05). There were statistically significant differences in tumor vascular tumor thrombus, AFP, postoperative tumor recurrence, and lymph node metastasis between Ck19 positive and negative groups (χ²=9.058, 27.034, 4.053, 14.187, all P less then 0.05), but not correlated with ADC value (r=0.062, P=0.380). The expression differences of Ki67 and Ck19 in different HCC recurrence time groups were statistically significant (P less then 0.05). Conclusion The positive expression of Ki67 and Ck19 in HCC was associated with the prognosis and recurrence of HCC. CK19 was not correlated with the ADC value, while Ki67 was negatively correlated with the ADC value, indicating that ADC value could provide certain imaging information for the biological characteristics of preoperative HCC.Objective To compare the intraoperative blood loss, postoperative drainage and hidden blood loss (HBL) in lumbar posterior lumbar interbody fusion (PLIF) in patients with and without rheumatoid arthritis (RA), and analyze the relevant factors of HBL in RA patients. Methods Fifty patients with RA (RA group) and 73 patients without RA (NRA group) treated in the Heze Municipal Hospital from January 2014 to April 2019 were enrolled in this study. The basic information, RA information, operation and related blood loss indicators in the two groups were compared. The intraoperative blood loss, postoperative drainage and HBL were the main results. The secondary results were operation time, preoperative and postoperative hematocrit (Hct) and hemoglobin (Hb) and their variation values, cases of anemia before and after surgery, number of new anemia after surgery, autologous blood and allogeneic blood transfusion, etc. The correlation factors of HBL in RA group were analyzed by multi-linear regression model. Results Therlogeneic blood were independently correlated to HBL (β=0.363, -0.272, 0.210, 1.204, all P less then 0.05). Conclusions There is no difference in TBL, intraoperative blood loss, postoperative drainage and operation duration between the RA and NRA group, while HBL and the proportion of HBL in the TBL are higher in the RA group. The RA group has higher Steinbrocker rating, no DMRDs and more Hb changes.Objective To evaluate the effects of neuromuscular exercise therapy on joint stability of knee osteoarthritis (OA) patients. Methods One hundred and ten patients with knee OA were enrolled in this ongoing prospective cohort study at Arthritis Clinic and Research Center, Peking University People’s Hospital from September 2017 to October 2018. The treatment consisted of six-week neuromuscular exercise therapy. The participants were followed up at 6 weeks and 3 months after the therapy. The stability of the joint was evaluated by the index of knee joint stability (IKJS), which was extracted by a novel knee-aiming task combined with the multiscale entropy (MSE) analysis of the complexity of the light spot trajectories. The secondary outcomes were pain on the visual analogue scale (VAS, 0-100), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), quality of life on the Euro-quality of life-5 Dimensional (EQ-5D) VAS form, 30-second chair stand test and 40-meter walk test. One-way repeated measures ANOVA analysis was applied to compare the outcomes at baseline and 6 weeks and 3 months. Pearson partial analysis was used to investigate the correlation between the IKJS and the Kellgren-Lawrence (K/L) rate, pain and knee function. Results Ninety-six participants ((65±8) years, 21 males, 75 females) completed 3-month follow-up. There was a significant improvement in IKJS at the 6-week visit compared with that at baseline (0.369, 95% confidence interval (CI) 0.241-0.496, P0.05). There was improvement in pain VAS, WOMAC, EQ-5D-VAS, 30-second chair stand test and 40-meter walk test at 6 weeks and 3 months (all P less then 0.05). Conclusion The neuromuscular exercise therapy is effective in improving the joint stability of the knee OA patients. However, the effect gradually diminished over time. In addition, neuromuscular exercise can help relieve pain, improve the function and quality of life in patients with knee OA.Objective To evaluate the long-term clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DES) for ostial/shaft lesions in patients with unprotected left main coronary artery (ULMCA). Method A total of 271 patients with isolated ostial/midshaft lesions in unprotected left main coronary artery who received drug-eluting stents (DES) implantation between January 2003 and July 2009 in Beijing An Zhen Hospital were consecutively enrolled . The endpoints of the study were all-cause death, repeat revascularization, myocardial infarction (MI) and stroke. Cox regression was carried out to analyze the all-cause mortality. Meanwhile, multivariate logistic regression analysis was performed to determine the independent risk factors of all-cause death. Results The mean age of the patients was (62±10) years, and 201 of them (74.2%) were male. The median follow-up was 12.5 years (interquartile range 10.1-14.5 years). During the follow-up, 46 patients (17.0%) died, of whom 20 (7.4%) died of a cardiovascular cause. A total of 38 (14.0%) cases suffered a MI, and 15 (5.5%) cases suffered a stroke. Repeat revascularization was performed in 63 (23.2%) cases. Multivariate logistic regression analysis showed that age (HR=1.041, 95%CI 1.003-1.081, P=0.033), creatinine (HR=1.028, 95%CI1.014-1.042, P less then 0.001) and diabetes mellitus (HR=1.924,95%CI 1.053-3.514, P=0.033) were independent risk factors of all-cause death, whereas left ventricular ejection fraction (LVEF) (HR=0.972, 95%CI0.953-0.992, P=0.007) was a protective factor. Conclusions During a median follow-up of 12.5 years, the prognosis of PCI for left main ostium/shaft lesion was good. Age, creatinine and diabetes mellitus are independent risk factors of all-cause death.Objective To investigate the effect of remote ischemic preconditioning (RIPC) on contrast-induced acute kidney injury (CI-AKI) in patients with chronic total occlusion (CTO) after percutaneous coronary intervention (PCI). Methods A total of 282 patients undergoing PCI at Zhongda Hospital Affiliated to Southeast University between June 2017 and January 2019 were prospectively enrolled. The patients were randomly divided into RIPC group (n=142) and control group (n=140). CI-AKI was defined as an increase in level of cystatin C (CysC)≥10% above baseline at 24 h after contrast administration. Baseline characteristics and the incidence of CI-AKI were compared between the two groups. The multivariate logistic regression analysis was further used to analyze the independent risk factors of CI-AKI. Results There were no significant differences in age, gender, smoking, hypertension, diabetes, stroke and old myocardial infarction, coronary artery bypass graft surgery, previous PCI history and laboratory test indicators, target vessel and pathological characteristics of CTO lesions, contrast agent dosage, J-CTO (Multicenter CTO Registry in Japan) score, SYNTAX (Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery) score, PCI success rate and stent number between the two groups (P>0.05). The incidence of CI-AKI was significantly lower (18.3% vs 29.3%, P=0.036) in RIPC group than that of control group. Multivariate logistic analysis found that creatinine [odds ratio (OR)=1.018,95%CI 1.006-1.030, P=0.003], CysC (OR=5.200, 95%CI2.714-9.963, P less then 0.001),contrast agent dosage (OR=1.013,95%CI 1.007-1.019, P less then 0.001) and J-CTO score (OR=1.834, 95%CI 1.145-2.939, P=0.012) were independent risk factors of CI-AKI. However, RIPC was an independent protective factor of CI-AKI (OR=0.391, 95%CI 0.199-0.765, P=0.006). Conclusion RIPC before contrast agent administration prevents CI-AKI in CTO patients undergoing PCI.Objective To investigate early postoperative changes in eosinophils (EOS) and the relationship of postoperative hospital stay and hypoeosinophilia in patients undergoing hip fracture surgery under general or spinal anesthesia. Methods The clinical data of patients who underwent hip fracture surgery at Beijing Tiantan Hospital between April 2014 and November 2017 were retrospectively analyzed. Patients were classified according to whether they received general anesthesia or spinal anesthesia. Univariate regression analysis was used to examine a number of covariates potentially contributed to postoperative hospital stay. Multivariate linear regression was used to analyze the relationship between postoperative day 1 EOS counts and postoperative hospital stay. Interaction and stratified analyses were conducted according to anesthesia methods. Results A total of 149 patients were included in this study. Thirty-four of them underwent general anesthesia and 115 of them underwent spinal anesthesia. The postoperative day 1 EOS of the general anesthesia group was 0 (0,1.8)×107/L, which was lower than that of the spinal anesthesia group 1.0(0,6.0)×107/L (Z=3.095, P less then 0.01). After adjusting the confounders of age, gender, American Society of Anesthesiologists (ASA) grade, intraoperative blood loss, intraoperative red blood cell (RBC) transfusion, postoperative day 1 hematocrit (HCT) and white blood cell (WBC), postoperative complications, and the interaction terms for ASA, intraoperative blood loss, intraoperative RBC transfusion and postoperative complications, the negative correlation between postoperative hospital stay and postoperative day 1 EOS level was significant (β=-0.39, 95%CI-0.74–0.05, P less then 0.05) in the general anesthesia group. Conclusion EOS were significantly decreased after surgery in general anesthesia group, and the postoperative hospital stay was negatively correlated with postoperative day 1 hypoeosinophilia.Objective To investigate the digital subtraction angiography (DSA) manifestations of hemorrhage after partial nephrectomy (PN) for renal tumors, and the safety and efficacy of interventional therapy. Methods The clinical data, DSA images and interventional treatment of 15 patients undergoing emergency interventional therapy due to hemorrhage after PN in the Department of Interventional Therapy of Beijing University Cancer Hospital from January 2015 to January 2019 were retrospectively analyzed. The DSA manifestations, safety and prognosis of interventional therapy were summarized. Results Among the 15 patients, 10 had abdominal hemorrhage, 2 had abdominal hemorrhage with hematuria, and 3 had hematuria, all of which occurred 6 hours to 7 days after the operation. The DSA manifestations included contrast medium overflow, local artery wall unevenness, local artery branch expansion, pseudoaneurysm formation and renal arteriovenous fistula. There were 14 survivors, followed up for 6-12 months, and further no bleedrrhage after PN. Interventional therapy was safe and effective and might be a priority in cases of hemorrhage after PN.Objective To investigate the influence of X-ray repair cross complementing 1 (XRCC1) gene polymorphism on the prognosis and safety of stage Ⅲ patients with colorectal cancer (CRC) who received oxaliplatin based adjuvant chemotherapy. Methods A total of 218 stage Ⅲ patients with CRC after R0 resection and received oxaliplatin based adjuvant chemotherapy in the department of gastrointestinal surgery of the First Affiliated Hospital of Zhengzhou University from March 2012 to December 2019 were included and the baseline characteristics were collected. There were 125 male and 93 female patients, aged from 18 to 78 years. Peripheral blood and peripheral blood mononuclear cell (PBMC) specimens of the colorectal cancer patients were preserved for genotyping of XRCC1 gene genetic variation and mRNA expression of XRCC1, respectively. The association between genotype status and prognosis was analyzed by Kaplan-Meier survival analysis. And the correlation between genotype status and adverse reactions was performed with χthan that of the GG genotype patients(2.8±0.7) (t=6.140, P less then 0.001). Conclusion The prognosis of patients with CRC who received oxaliplatin based adjuvant chemotherapy may be influenced by XRCC1 rs1799782 through mediating the mRNA expression of XRCC1.One 51 years old man was admitted to the rheumatology department with a history of prominent eyes, headache and blurred vision for half year. The main manifestations included retrobulbar inflammatory pseudotumor and retroperitoneal fibrosis. He was initially diagnosed as granulomatosis with polyangiitis. Prednisone and cyclophosphamide were administrated and effective. New mass of dura mater and osteosclerosis presented during follow up. Finally Erdheim Chester disease(ECD) was diagnosed by biopsy and pathological examination. Vemurafenib, a v-raf murine sarcoma viral oncogenes homolog B1 (BRAF) inhibitor, 480 mg was given twice a day. The patient’s condition is stable and still in follow-up. Although ECD is a rare histiocytosis, clinicians should pay attention to its manifestations and differential diagnoses.To investigate the clinical manifestations and imaging characteristics of patients with different types of infectious sacroiliitis. Clinical data of 40 patients diagnosed with infectious sacroiliitis were retrospectively analyzed. Among the 40 patients, 16 patients were diagnosed as non-brucellar and non-tuberculous infectious sacroiliitis (ISI), 13 with tuberculous infectious sacroiliitis (TSI), and 11 with brucellar sacroiliitis (BSI). In the ISI and TSI group, female patients accounted for 11/16, 12/13, while the proportion of unilateral involvement was 15/16 and 12/13, respectively. Compared with ISI and TSI group, BSI patients were mainly male (8/11) and presented more bilateral involvement (6/11) (P less then 0.05). Bone erosion was more common in ISI and TSI groups than in BSI group (6/15, 7/11 and 2/10), as well as abscess formation (3/15, 4/11 and 1/10, respectively). Symptoms in all patients relieved 1-2 weeks after administration of antibiotics or anti-tuberculosis treatment, but the resolution of the magnetic resonance imaging findings delayed about 6 (3-9) months. ISI and TSI patients with infectious sacroiliitis should be differentiated from spondyloarthritis, with a characteristic of more female patients, unilateral sacroiliitis, bone erosion, soft tissue involvement and abscess formation. However, BSI patients are mainly male, more bilateral involvement and less bone destruction and abscess formation. Antibiotic therapy demonstrates significant therapeutic effects, but resolution of the magnetic resonance imaging findings responses late.Objective To investigate the effect of focal adhesion kinase related non kinase (FRNK) on the activation and migration of hepatic stellate cells (HSCs). Methods Human liver tissue was divided into healthy control group and fibrosis group from March 2019 to September 2019 in Affiliated Hospital of Guizhou Medical University. C57BL/6 mice were divided into wild type (WT) and FRNK gene knockout type (FRNK-/-) groups. The liver fibrosis model was established with carbon tetrachloride (CCl4). After that, FRNK gene overexpression (Ad-FRNK) was constructed with adenovirus vector. HE and Masson staining were used to evaluate the pathological changes and fiber deposition of liver tissue. Western blot was used to detect the expression of PY397-FAK and α-SMA protein. Mouse primary HSCs were extracted, and the effect of FRNK on HSCs migration was detected by wound healing, activation of Rac and Rho was detected by Western blot. Results The expression of PY397-FAK protein in human liver tissue with hepatic fibrosis was sid to down regulation of PY397-FAK and inhibition of Rac and Rho activation.Objective To evaluate the diagnostic value of hydrogen sulfide breath test(SBT) for small intestinal bacterial overgrowth (SIBO). Methods College students were enrolled to complete gastrointestinal symptom scale, food frequency questionnaire, lactulose hydrogen- methane breath test (LHMBT) and SBT. Based on the correlation between hydrogen sulfide(H2S) and hydrogen or methane gas,the receiver operating characteristic (ROC) curve of H2S was drawn and diagnostic criteria of SBT was defined. Results A total of 300 subjects including 84 males and 216 females with age 17-32 (21.6±2.4) years were enrolled from April 2019 to December 2019 and divided into two groups.Two hundred and three patients reported SIBO discomforts with 99 (48.8%) LHMBT positive, while 38 (39.2%) were LHMBT positive in 97 health controls. Rise of H2S at 90 min was positively related with that of hydrogen (r=0.516, P less then 0.01), and H2S levels at 90 min were positively correlated with methane (r=0.632, P less then 0.01). A rise in H2S of ≥25.0 ppb or H2S levels ≥62.5 ppb at 90 min during lactulose breath test was considered positive for SIBO, that sensitivity, specificity and accuracy were 66.4%,79.1% and 73.3% respectively. H2S levels were significantly related to the amount of Vitamin B12 intake (P=0.011). H2S-positive subjects exhibited a constipation-predominant pattern. Conclusion SBT is consistent with LHMBT, especially in constipation-predominant patients, which may provide a reference to the diagnosis of SIBO.Objective To investigate the predictive value of myoglobin (Mb) for the prognosis of sepsis related chronic critical illness (CCI). Methods Retrospective study was conducted on septic patients with the length of ICU stay equal or greater than 14 days, and sepsis-related organ failure assessment (SOFA) score equal or greater than 2 on the 14th day in ICU in the First Department of Critical Care Medicine at the First Affiliated Hospital of Sun Yat-sen University from January 2017 to March 2020. Patients’ clinical and laboratory data were collected on the 1st and 14th day in ICU. The survival on day 28 in ICU was recorded. According to the myoglobin levels on day 1 and day 14, all subjects were divided into myoglobin elevation group and decline group. Kaplan-Meier survival curve was used to compare the cumulative survival rate at day 28. Cox regression analysis was used to analyze the independent risk factors of mortality. Receiver operating characteristic (ROC) curve was used to analyze the prognostic value of ecificity was 32.0% with area under the curve(AUC) 0.661(95%CI 0.550-0.773,P=0.007) and Jorden Index was 0.325. Conclusion Elevated myoglobin, an independent risk factor for mortality within 28 days in ICU, can predict the prognosis of sepsis related chronic critical illness.Objective To explore the clinical characteristics of patients with pituitary thyrotropin-secreting adenoma and evaluate the effect of preoperative short-acting octreotide treatment on hyperthyroidism. Methods A retrospective analysis was performed in 40 patients with pituitary thyrotropin adenoma diagnosed in Beijing Tiantan Hospital from January 2008 to January 2018. The general data, laboratory examinations and imaging findings were reviewed and analyzed. The clinical effect of preoperative octreotide on hyperthyroidism was evaluated. Results The age of onset year of the 40 patients (male female = 24∶16) was (30.5±5.1) years. Among them, 35 patients (87.5%) were with macroadenoma. The most common symptoms were thyroid hypermetabolism syndrome, followed by headache, dizziness, visual field damage and hypogonadism. The thyroid function of 30 patients (75%) recovered to normal within 3-5 days after the octreotide treatment. The total effective rate of the octreotide was 90.0%. The level of free thyroxine (FT4) before treatment in patients with more than 10 times of effective cumulative dose was significantly higher than that in patients with less than 10 doses. Conclusions Thyroid hypermetabolism syndrome and pituitary occupying effect are the most common clinical manifestations of thyrotropin-secreting adenoma. Preoperative octreotide treatment can effectively control hyperthyroidism. The level of FT4 is a crucial factor affecting the efficacy of octreotide.Objective To investigate the prevalence and associated risk factors of pre-hypertension and hypertension in young and middle-aged population in Nanjing. Methods Subjects of the study were those who underwent physical examination in the physical examination center of Nanjing Drum Tower Hospital from 2009 to 2016. The prevalence and risk factors of pre-hypertension and hypertension in young (aged 18-44 years old) and middle-aged people (aged 45-59 years old) were analyzed. Results A total of 142 857 participants aged 18-59 years old were analyzed. Among them, 64 220 cases in the pre-hypertension group and 13 912 cases in the hypertension group. The prevalence of hypertension was 9.74% (12.51% in males and 5.82% in females). The prevalence of pre-hypertension was 44.95% (53.31% in males and 33.15% in females). In the middle-aged group, the prevalence of pre-hypertension and hypertension were 51.68% and 15.13%, respectively, which was higher than that in the young group (37.95% and 4.13%, respectively). The prevartension in both men and women. Intervention on the related risk factors should be conducted as early as possible.Objective To investigate the current situation of insomnia in patients with acute coronary syndrome (ACS), and analyze the influencing factors of insomnia in the ACS patients, so as to provide information on the development of new strategies for the treatment of insomnia in ACS patients. Methods This is a multicenter and prospective observational study. A total of 771 ACS patients who met the criteria were selected from March 2013 to June 2015. The baseline social demographic information, sleep quality questionnaire, general anxiety disorder scale-7(GAD-7),patient health questionnaire-9(PHQ-9), short-form 12 health survey questionnaire(SF-12), and enhancing recovery in coronary heart disease patients social inventory(ESSI) were completed within 7 days after admission. Logistic regression analyses were used to analyze the influencing factors of insomnia in ACS patients. Results A total of 741 subjects with valid questionnaires were collected, including 510 males (68.8%) and 231 females (31.2%). Among them, 487 (65.7%) subjects had at least one insomnia symptom 308 (41.6%) subjects had difficulty in falling asleep, 369 (49.8%) subjects were easy to wake at night, 116 (15.7%) subjects woke up earlier than they expected, 74 (10.0%) subjects experienced both woke up earlier and difficulty in falling asleep, and 53 (7.2%) subjects woke up earlier, woke up at night and had difficulty in falling asleep at the same time. Logistic regression analyses showed that before admission physical activity (OR =0.636, 95%CI 0.411-0.984), depression (OR=1.908, 95%CI 1.101-3.305) and low social support (OR=0.278, 95%CI 1.198-3.301) were independent factors of insomnia in ACS patients. Conclusions Nearly 2/3 ACS patients have symptoms of insomnia. Difficulty in falling asleep and easy to wake up at night are the most common manifestations. Physical activity, depression and social support independently are associated with insomnia.Fabry disease is a rare X-linked genetic lysosomal storage disorder caused by mutations in the GLA gene, which results of reduced or absent activity of α-galactosidase A, accumulation of metabolic substrates globotriaosylceramide (GL-3) and derivatives deacylated derivative globotriaosylsphingosine (Lyso-GL-3) in multiple tissues, and multi-organ diseases and even life-threatening complications. Due to the lack of specific symptoms, there is a need to combine the clinical features and the results of enzymatic, biochemical, and genetic tests to realize the early definite diagnosis of Fabry disease. Furthermore, the approval of agalsidase beta/alpha in China will benefit the vast Chinese patients for Fabry disease specific therapies. Based on the evidence-based medicine, this consensus summarizes several main aspects related to Fabry disease, including clinical manifestations, diagnosis and its flow chart, therapies, screening, genetic counseling and prenatal diagnosis, so as to further promote the standardized diagnosis and treatment of Fabry disease.
