Objective: To investigate activities of lipo-related enzymes in ventromedial hypothalamic obese rats at acute phase in fed state. Methods: Female SD rats were divided into two groups, one group received bilateral electrolytic lesions of ventromedial hypothalamus(VMH), and another one was used as sham control. Samples of blood, livers, and subcutaneous, parametric and mesenteric adipose tissues ,and gastrocnemius were collected one week after VMH lesions and sham operations in fed state. Results: Serum insulin in VMH group was higher than that in sham group, meanwhile serum free fatty acids in VMH group were lower (P

Objective: To investigate the effects of green tea polysaccharides (TPs) on glucose metabolism and the activity of peroxisome proliferator-activated receptor gamma (PPAR-?) in KKAy type 2 diabetic mice. Methods: Glucose tolerance test, fasting and postprandial glucose, gluconeogenesis, and insulin sensitivity were investigated in type 2 diabetic mice with orally administered TPs at the dose of 500mg/kg for 4-10 w. Effect of TPs on activity of PPAR-? was tested in vitro. Results: TPs could not only improve glucose tolerance, but also reduce fasting and postprandial blood glucose. In addition, TPs could inhibit gluconeogenesis and enhance insulin sensitivity in KKAy diabetic mice. TPs had also an effect of activating of PPAR-? with dose-response. Conclusion: TPs have beneficial effect of lowering blood glucose in KKAy type 2 diabetic mice, which may be induced by enhancing insulin sensitivity by activating of PPAR-?.

Objective:To identify and screen the differential methylation genes in patients with cholangiocarcinoma and to predict the prognosis of patients with CCA.Methods:Cholangiocarcinoma tissues and paracancerous tissues of 8 patients with cholangiocarcinoma in Fujian Provincial Hospital from October 2019 to May 2020 were selected for 850K methylation sequencing analysis to obtain differentially methylated genes. The 2018 genome-wide methylation data and clinical information of 36 patients with cholangiocarcinoma were download from The Cancer Genome Atlas (TCGA) database, the 2012 cholangiocarcinoma methylation data (GSE32879) were download from the Gene Expression Omnibus (GEO) database, and the 2018 TCGA database differential survival genomic data of overall survival (OS) and disease-free survival (DFS) of cholangiocarcinoma were download from the GEPIA2 database. The differentially methylated positions (DMP) and differentially methylated regions (DMR) results of 850K methylation sequencing analysis of submitted samples, methylated genes in TCGA and GEO databases, and cholangiocarcinoma survival genes of samples were jointly submitted for testing, multi-data set analysis was performed by the Sangerbox VENN tool, and common differentially methylated genes were obtained by intersection screening. The minimum P value method was used to determine the cut-off value of gene expression in Sangerbox, and the patients were divided into high and low expression groups of differentially methylated genes. The OS, DFS, disease-specific survival (DSS), disease-free interval (DFI) and progression-free interval (PFI) of cholangiocarcinoma patients were compared between the two groups. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed. Results:A total of 121 954 DMP were identified by 850K methylation sequencing of cholangiocarcinoma tissues and paracancerous tissues of 8 patients; a total of 1 399 differentially methylated genes were identified in DMR, and the common prognosis related genes glucosaminyl (N-acetyl) transferase 1 (GCNT1) and neurotrophic receptor tyrosine kinase 3 (NTRK3) were identified by intersection identification. The expression of GCNT1 in the cholangiocarcinoma tissues was higher than that in the paracancerous tissues, and the difference was statistically significant ( P = 0.040). The expression of NTRK3 in cholangiocarcinoma tissues was higher than that in the paracancerous tissues, but the difference was not statistically significant ( P = 0.790). The minimum P value method was used to predict the prognosis of patients with cholangiocarcinoma based on the combined expression of GCNT1 and NTRK3, and the order was based on the sum of the expression levels of the two genes. When 30% of the ranking was taken as the cut-off value, the difference in DFS between the high expression group and the low expression group in cholangiocarcinoma was the most significant ( P < 0.001); there was no significant difference in OS between the two groups ( P = 0.065). The results of GO functional analysis showed that GCNT1 was involved in protein glycosylation, macromolecule glycosylation, glycosylation, glycoprotein biosynthetic process, glycoprotein metabolic process, transferase activity and transferring glycosyl groups, protein O-linked glycosylation, O-glycan processing, etc., and NTRK3 was involved in neurotrophin signaling pathway, Ras signaling pathway, EGFR tyrosine kinase inhibitor resistance, ErbB signaling pathway, phospholipase D signaling pathway, central carbon metabolism in cancer, natural killer cell mediated cytotoxicity, etc. The results of KEGG analysis showed that GCNT1 was mainly associated with system functions such as mucin-type O-glycan biosynthesis and metabolic pathways, and NTRK3 was mainly associated with cell surface receptor pathways, intracellular signal transduction, positive regulation of stimulatory responses, transmembrane receptor protein tyrosine kinase signaling pathway, enzyme-linked receptor protein signaling pathway, MAPK signaling pathway cascade and regulation, protein phosphorylation signal transduction and other system functions. Conclusions:The expressions of differentially methylated genes GCTNT1 and NTRK3 in cholangiocarcinoma have certain predictive effects on the prognosis of patients with cholangiocarcinoma.

This paper mainly analyzes the literature on the training system of physiotherapists at home and abroad in the past 15 years, and compares the training mode, curriculum setting, current situation and application direction of physiotherapists domestic and abroad. The main findings are as follows: at present, the training objectives of Chinese physiotherapists are not clear, the training methods and teaching materials are outdated, the source of teachers are not standardized, the identification of professional qualifications are not completed, and the gap between relevant talents and market demand is large. It is suggested to establish a standardized curriculum and syllabus for physiotherapists, develop a unified industry access and qualification recognition, formulate a training mode which is in line with the national conditions, and focus on solving the imbalance between supply and demand of physiotherapists.

OBJECTIVETo investigate the association between maternal serum neutrophil-lymphocyte ratio (NLR) and placental inflammatory response (PIR) in late pregnancy.

METHODSWe retrospectively analyzed the clinical and follow-up data of 478 pregnant women undergoing routine prenatal examination and delivery in our hospital in the year 2016. According to the placental pathological results, the women were divided into PIR group (238 cases) and control group (240 cases). The levels of serum inflammatory makers including leukocytes, neutrophils, lymphocytes, C-reactive protein (CRP) and NLR were compared between the two groups to analyze the association of these markers with PIR. Multivariate analysis was performed to identify the independent risk factors of PIR. Logistic regression model was established and the area under the receiver operating characteristic curve (ROC) was used for analyzing the prognostic value of these makers in late pregnancy.

RESULTSThe areas under the curve (AUC) of leukocytes, neutrophils, lymphocytes, CRP and NLR were 0.698 (95%: 0.485-0.766), 0.716 (95%: 0.453-0.783), 0.329 (95%: 0.228-0.431), 0.725 (95%: 0.677-0.765) and 0.801 (95%: 0.742-0.856), respectively. After adjusting the confounders, multivariate logistic regression analysis showed that preterm labor (OR=2.446, 95%: 1.003-4.590), premature rupture of membranes (OR=2.304, 95%: 1.049-4.161), NLR > 7 (OR=3.268, 95%: 2.071-6.920), and CRP > 15 mg/L (OR=2.137, 95%: 1.412-8.236) were independent risk factors for PIR.

CONCLUSIONSAn increased NLR in late pregnancy can serve as an effective indicator for predicting the risk of PIR.
