Multivariate analysis suggested that the pathological type (OR=0.120,

=0.025), station 5 metastasis (OR=18.784,

=0.007) and station 10 metastasis (OR=5.233,

=0.044) were independent risk factors for 4L metastasis in patients with left non-small cell lung cancer.

In patients with left non-small cell lung cancer, station 4L metastasis is not rare and is more likely to occur in patients with lung adenocarcinoma. Dissection of the 4L lymph nodes should be performed in cases with low risk of damages of the adjacent tissues and high risk of station 4L metastasis.

To explore the mechanism by which fractalkine (CX3CL1; FKN) inhibits lipopolysaccharide (LPS)-induced immunological response in RAW264.7 cells.

A RAW264.7 cell model overexpressing FKN was established by transfection with the lentiviral vector CX3CL1. The effects of LPS, ICG-001 (a Wnt/β-catenin signaling pathway inhibitor), either alone or in combination, on M1 polarization of na?ve and FKN-overexpressing RAW264.7 cells were evaluated by detecting of intereukin-6 (IL-6) and tumor necrosis factor-α (TNF-

) using ELISA. The protein expressions of the inflammatory factors (iNOS, TNF-

, and IL-6), FKN, Wnt-4, and β-catenin were detected by Western blotting. The subcellular localization of IL-6 in the cells was detected by immunofluorescence assay.

The RAW264.7 cell model of FKN overexpression was successfully established. In na?ve RAW264.7 cells, treatment with both ICG-001 and LPS, as compared with LPS alone, significant promoted TNF-

and IL-6 secretions, increased intracellular levels of TNF-

, IL-6 and iNOS (

< 0.05), and reduced intracellular FKN, Wnt-4 and β-catenin levels (

< 0.01). In FKN-overexpressing RAW264.7 cells, LPS treatment significantly reduced the secretion of TNF-

and IL-6 and intracellular levels of TNF-

, IL-6 and iNOS (

< 0.01), increased intracellular FKN, Wnt-4 and β-catenin protein contents (

< 0.01), and inhibited IL-6 localization in the cytoplasm; compared with LPS, the combined treatment with ICG-001 and LPS obviously enhanced IL-6 localization in the cytoplasm of the cells.

FKN overexpression suppresses LPS-induced M1 type polarization of RAW264.7 cells by activating Wnt/β-catenin signaling pathway.

To observe the effect of

(YHPC) granule on miR-139-5p, Notch1/Hes1 pathway and homing of bone marrow-derived mesenchymal stem cells (BMSCs) in asthmatic rats.

Fifty SD rats were randomized divided into normal control (NC) group, asthmatic model group, BMSCs transplantation group, BMSCs + dexamethasone (0.0625 mg/kg daily) group, and BMSCs+YHPC granule (3.5 g/kg daily) group. In all but the normal control group, asthmatic rat models were established by ovalbumin challenge, and BMSCs (1×10

/mL) transplantation

the tail vein was performed in the latter 3 groups on last day of ovalbumin challenge. In all the groups, lung pathologies of the rats were evaluated using HE staining after the treatments. Flow cytometry was employed to detect pulmonary expression of CXCR4 protein, and ELISA was used to determine the expressions of interferon-γ (IFN-γ) and interleukin-4 (IL-4) in the lung tissue. The expressions of CXCR4, Notch1 and Hes1 in bronchial epithelial cells was examined using immunofluorescence assaycan enhance the inhibitory effect of BMSCs homing on Th2 inflammatory response in asthmatic rats by up-regulating miR-139-5p and down-regulating Notch1/Hes1 pathway.

To identify mitochondrial gene variants associated with statin-induced myalgia in Chinese patients with coronary artery disease (CHD).

This study was conducted in a cohort of 403 patients with CHD receiving rosuvastatin therapy, among whom 341 patients had complete follow-up data concerning myalgia and 389 patients had documented measurements of plasma creatine kinase (CK) level. All these patients underwent genetic analysis using GSA chip for detecting mitochondria gene variants associated with myalgia. A logistic regression model was used to assess the association between 69 mitochondrial single-nucleotide polymorphisms (SNPs) and myopathy in 341 patients. The impact of these mutation sites on CK levels in 389 patients was evaluated by linear regression analysis.

G12630A variant was identified to correlate with an increased risk of myalgia in CHD patients (OR 8.689, 95%

1.586-47.6;

=0.01273), but CK levels did not differ significantly between patients with different genotypes of G12630A (

> 0.05). SNPs at T12285C and A13105G were found to significantly correlate with CK levels in these patients (

< 0.05).

Mitochondrial G12630A variation is associated with statin-induced myalgia in patients with CHD, indicating the necessity of different treatment strategies for patients who carry this risk allele.

To investigate the intra- and inter-scanner reproducibility of quantitative susceptibility mapping (QSM) of cerebral subcortical nuclei in healthy adults.

QSM was performed in 21 healthy adults on two different 3.0T MR scanners, and the region of interest (ROI) method was used to measure the magnetic susceptibility value of the left subcortical nuclei (the head of the caudate, putamen, globus pallidus, thalamus, substantia nigra and red nucleus). The intraclass correlation coefficient (ICC) and Bland-Altman method were used to evaluate the inter-scanner and intra-scanner reliability.

The ICCs of the susceptibility value ranged from 0.90 to 0.99 for all the subcortical gray nuclei except for the head of the caudate nucleus measured on the same MR scanner by the same observer. Bland-Altman analysis revealed that the points with susceptibility differences for all the subcortical gray nuclei except for substantia nigra located in the 95% CI of limits of agreement for the same MR scanner. The ICCs of the susceptibility value for the inter-scanner was 0.49 (0.08-0.75) for the head of the caudate nuleus, 0.80 (0.57-0.91) for the putamen, 0.77 (0.51-0.90) for the globus pallidus, 0.78 (0.54-0.91) for the thalamus, 0.80 (0.56-0.91) for the substantia nigra and 0.93 (0.83-0.97) for the red nucleus. The points with susceptibility difference (95.2%, 20/21) located in the 95% CI of limits of agreement for the putamen and the thalamus measured on two different MR scanners.

The intra-scanner reproducibility of QSM of the subcortical gray nuclei is superior to the inter-scanner reproducibility in healthy adults.

The intra-scanner reproducibility of QSM of the subcortical gray nuclei is superior to the inter-scanner reproducibility in healthy adults.ObjectiveTo evaluate the efficacy and safety of IEAC (idarubici, etoposide, cytosine arabinoside, and cyclophosphamide) and CEAC (lomustine, etoposide, cytosine arabinoside, and cyclophosphamide) high-dose chemotherapy followed by autologous hematopoietic stem cell transplantation (ASCT) in the treatment of lymphoma.MethodWe retrospectively analyzed the data of 106 lymphoma patients undergoing ASCT from 2013 to 2018 using IEAC (n=43) or CEAC (n=63) regimens. The time of hematopoietic reconstruction, adverse events and the patients’ survival outcomes in the two groups were compared to evaluate the efficacy and safety of the two regimens. Univariate and multivariate analyses were performed to identify the factors potentially affecting the patients’ survival.ResultsIn the total of 106 patients, successful hematopoietic reconstruction was achieved in 104 patients and treatment-related deaths occurred in 2 patients. No significant differences were observed in the time to hematopoietic recovery, adverse events or srnative conditioning regimens for lymphoma patients undergoing ASCT.

To analyze the characteristics of cervical microecology in late reproductive-age women with cervical lesions and explore new methods for preventing cervical lesions.

Cervical smears were obtained from a total of 147 women of late reproductive age, including 24 with high-risk HPV infection (HR-HPV), 27 with low-grade squamous intra-epithelial lesions (LSIL), 36 with high-grade squamous intra-epithelial lesions (HSIL), 35 with cervical cancer (CC) and 25 healthy women. llumina MiSeq sequencing of V3-V4 region of the 16S rRNA gene amplicons was used to characterize the vaginal microbiota of the women. OTUs analysis of the valid data was performed, and the α-diversity (Chao1, Simpson’s Index and Shannon Index) and β-diversity (T-test, weighted UniFrac β diversity, and MetaStat analysis) were evaluated.

Dilution curve and species accumulation boxplot validated the quality of the samples. OTUs analysis of the 5 groups demonstrated that cervical bacterial genus consisted primarily of

,

and

. With the agical factors, physiological factors also contribute to the difference in α-diversity. Women with LSIL have the most similar cervical flora to healthy women, which is consistent with the prognosis of the disease and confirms that the expression of cervical microecology is related to disease prognosis and may serve as a biological indicator for favoralble prognosis.

The abundance of Lactobacillus, Gardnella and Proctella is the highest in cervical bacteria at the genus level and may vary with disease progression. The α-diversity does not differ significantly, suggesting that apart from pathological factors, physiological factors also contribute to the difference in α-diversity. Women with LSIL have the most similar cervical flora to healthy women, which is consistent with the prognosis of the disease and confirms that the expression of cervical microecology is related to disease prognosis and may serve as a biological indicator for favoralble prognosis.

To study the difference in age estimation based on quantitative analysis of DNA methylation by MassARRAY and pyrosequencing techniques.

The methylation levels of 9 CpG sites from two independent whole blood sample sets (containing 65 and 62 samples) were detected using MassARRAY and pyrosequencing techniques. Z-score transformation was used to remove the batch effects of different techniques, and a linear regression model was used for age prediction.

For age prediction using the MassARRAY system, the 65 samples showed a mean absolute difference (MAD) of 2.49 years before Z-score transformation of the data and 2.44 years after the transformation, similar to the results in the 62 samples (MAD of 3.36 years before and 3.42 years after Z-score transformation). For data typed from pyrosequencing, the 65 samples showed a MAD of 4.20 years before and 2.76 years after data Z-score transformation, also similar to the results in the 62 samples (MAD of 3.92 years before and 3.63 years after data transformation).

Z-score transformation can effectively reduce the system batch effect between MassARRAY and pyrosequencing.
