Objective To investigate the effect of microcireulation blood flow and altering immunity by Chuanxiongqin,ulinastain and thymosin α1 on sepsis patients.Methods 90 patients were randomly divided into 3 groups(n=30),namely ICU group,Chuanxiongqin group,ulinastain and thymosin α1 group.HLA-DR/CD14+and IL-6,TNF-α,Lac,DD were measured.Results (1)DD showed no significant difference at every time point between ICU group and ulinastain+thymosin α1 group(P＞0.05).DD decreased in Chuanxiongqin group,and was significantly different from the others on the third day.(2)Lac unchanged significantly at every time point in ICU group(P＞0.05).Lac in Chuanxiongqin group and ulinastain+thymeain α1 group tended to decrease,and was statistically different from ICU group on the second day.(3)IL-6 and TNF-α tended to increase at every time point in ICU group(P＜0.05).In ulinastain+thymosin α1 group,IL-6 and TNF-α returned to the level before treatment,HLA-DR/(D14+increased significantly,and was higher than Chuanxiongqin group and ICU group statistically.Conclusion Chuanxiongqin could ameliorate circulation;ulinastsin and thymosin α1 could depress IL-6,TNF-α.So ulinastain and thymosin α1 might protect the immunity of sepsis patients.

Objective This study aims to investigate the effects of high-fat diet rich in perilla oil on the insulin sensitivity-related gene expression in skeletal muscle in insulin resistant rats.Methods The insulin resistant ( IR) rat models were randomly divided into 2 groups, including high fat group ( HF) and perilla oil ( PO) intervention group fed with 20%substitution of lard energy in the HF.The insulin sensitivity of rats was measured after 4 weeks.Theα-linolenic acid ( ALA) content of PO in the rat plasma were analyzed by gas chromatograph.Real-time PCR was applied to measure glucose transporter 4 ( GLUT4 ) and insulin receptor substrate-1 ( IRS-1 ) mRNA, and Western blot assay was used for detecting the expression of GLUT4 and IRS-1 in the skeletal muscle.Results At the gene and protein levels, PO remarkably reduced the level of IRS-1 and upregulated the level of GLUT4 with increasing intake of ALA and serum ALA content in IR rats.The results of hyperinsulinemic-euglycemic clamp test showed no significant difference between the two groups.Conclusions The results of our study suggest that consumption of n-3 PUFA at levels that can typically be found in the diet fed to IR rats in the form of ALA (0.556 g/d) may not improve insulin sensitivity, even though regulating the expression of GLUT4 and IRS-1 in the skeletal muscle.

Objective This study aims to investigate the effects of high-fat diet rich in perilla oil on the expression of key genes that regulate hepatic VLDL synthesis in obese rats .Methods Sixty healthy male 5-week old SD rats were randomly divided into 2 groups.The rats in the normal control group (NC, n=12) were given normal diet, and the rats in the high fat group ( HF, n=48) were given a pure high fat diet in order to induce rat models of obesity .In the intervention period, the obesity model rats were randomly divided into 4 subgroups including consistent high fat group (CHF) and three intervention groups depending on perilla oil substitution rate of lard in CHF:20%PO, 50%PO and 100%PO.The serum triglyceride (TG) of the rats was measured after 4 weeks.Real-time PCR was applied to measure microsomal triglyceride transfer protein ( Mtp) and apolipoprotein B ( Apob) mRNA, and western blot assay was used for detecting the expression of MTP and APOB in the liver .Results Compared with the NC group , the CHF rats exhibited significantly high fat deposi-tion.The serum TG was markedly higher and the MTP and APOB were decreased at gene and protein levels in the CHF group compared with the NC group .After the intervention , PO remarkably reduced the level of serum TG and decreased he-patic fat deposition as it showed by pathological examination .At the gene and protein levels , MTP and APOB were upregu-lated by PO to different degrees .Conclusions All the three PO intervention can promote VLDL synthesis and secretion , and decrease the hepatic fat deposition in the obese rats .Furthermore , PO upregulates the expression of MTP at gene and protein levels in a dose-dependent manner .
