AIM:To investigate the effect of paeoniflorin(PF)on TLR4/MyD88 signaling pathway in liver of rats with metabolic dysfunction-associated fatty liver disease.METHODS:SPF grade male SD rats were randomly divid-ed into four groups:normal control(NC)group,model control(MC)group,low-dose paeoniflorin(PL)group,and high-dose paeoniflorin(PH)group.The normal group was given standard diet,and the other three groups were given high-fat diet for 8 weeks.From the fifth week,rats in paeoniflorin groups were given low dose(25 mg·kg-1·d-1)or high dose(50 mg·kg-1·d-1)paeoniflorin for 4 weeks.Serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),total cholesterol(TC)and triglyceride(TG)were measured by biochemical method.The levels of tumor necrosis factor(TNF)-α was detected by ELISA.Pathological change of the liver was detected with hematoxylin-eosin(HE)staining and oil red O staining,and evaluated semi-quantitatively with the nonalcoholic fatty liver disease activity score(NAS).The expres-sion levels of TLR4,MyD88 and phosphorylated nuclear factor(p-NF)-κB p65 in liver tissues were detected by immuno-histochemistry and Western blot.RESULTS:Compared with the NC group,rats in the MC group showed increased TC,TG,ALT,AST and TNF-α in serum(P<0.05),and more lipid droplets in hepatocytes and inflammatory cell infiltration in the portal area,with higher NAS,TLR4,MyD88 and p-NF-κB p65 proteins in liver tissue(P<0.05).However,pae-oniflorin could reduce TC,TG,ALT,AST and TNF-α in serum(P<0.05),improve histopathological changes of liver,decrease the NAS scoring(P<0.05),and inhibit hepatic TLR4/MyD88/p-NF-κB p65 expressions(P<0.05).CONCLU-SION:Paeoniflorin could improve the lipid metabolism disorder and reduce liver inflammation during MAFLD,and the latter effect might be in part related to the inhibition of TLR4/MyD88 signaling pathway.

Objective To explore the role of neck circumference (NC) in identifying central obesity. Methods A community-based cross-sectional survey was conducted from October 2010 to January 2011 in Shipai community,Guangzhou. A total of 1494 subjects(72.8%)aged over 50 were investigated. Height,weight,waist circumference (WC) and NC were measured in all subjects. Central obesity was defined by the standard in the 2013 China Guideline(WC≥90.0 cm for men or WC≥85.0 cm for women). Results The median age of 1473 subjects with complete data was 61 years(55~68 years). NC was significantly positively correlated with WC and body mass index(correlation coefficient was 0.639 and 0.565,respectively,P<0.001). ROC curves showed that the area under the curve for the ability of neck circumference to determine visceral adiposity was 0.884(95%CI:0.855 ~ 0.909,P < 0.0001)for men and 0.849(95%CI:0.824 ~ 0.872,P < 0.0001)for women. Moreover,in men ,a NC of 38.5 cm had a sensitivity of 75.2%and specificity of 85.4%,and in women ,a NC of 33.4 cm had a sensitivity of 84.8% and specificity of 69.4%,which were the optimal cutoffs for identifying central obesity. Conclusions NC could be used as an alternative for WC and body mass index to identify central obesity in Chi-nese subjects aged over 50 in community-based setting.
