To explore the changes in blood levels of lipopolysaccharide(LPS), lipopolysaccharide-binding protein(LBP),and soluble CD14 (sCD14), and their clinical significance in patients with severe chronic viral hepatitis B. blood levels of LPS were determined with chromogenic limulus amebocyte lysate assay, and LBP and sCD14 were assayed with ELISA in 24 patients of severe chronic viral hepatitis B. 10 normal subjects and 16 patients with chronic hepatitis B were also enrolled as controls. The results showed that the blood levels of LPS, LBP and sCD14 were significantly higher in patients with the early stage, midterm, late periods of severe chronic viral hepatitis B than in normal subjects and in those with chronic hepatitis B. The blood levels of LPS, LBP and sCD14 were also significantly higher in patients who died of severe chronic viral hepatitis B than in survivors of the same disease. It suggested that when patients with severe chronic viral hepatitis B were complicated by intestinal endotoxemia (IETM), the sensitivity of Kupffer cells to endotoxin was significantly increased, resulting in hepatocyte injury by TNF ?,even in the presence of very low endotoxin concentration .

Objective To investigate expressions of programmed cell death ligand 1 (PD-L1) in hepatic tissues at the different stages of hepatitis B virus ( HBV) infection, and clarify its role in the mechanism of chronic hepatitis B virus infection. Methods The expressions of PD-L1 were detected by immunohistochemistry and computer image quantitative analysis in the hepatic tissues of 65 chronic HBV infected patients and 5 healthy controls. The correlations between PD-L1 expression and inflammatory grading in the hepatic tissues, total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), serum HBV DNA level were analyzed. Results The PD-L1 expressions in hepatic tissues of HBV infection with G0 - G4 inflammatory grades were 3. 07 % ±0.93%, 8.01%±1.49%, 11.60%±2.60%, 18.41%±2.21% and 26. 04% ±3. 41%, respectively,which were all significantly stronger than that in controls (0. 64%±0. 28%). PD-L1 expression was a positively correlated with inflammation grading of hepatitis tissues, TBil, ALT and AST level in serum (r=0. 917, 0. 787, 0. 483, 0. 628; all P<0. 05), and negatively correlated with serum HBV DNA load (r=-0. 620, P<0. 05). Conclusion The upregulated PD-L1 expression may be probably involved in the chronicity of HBV infection.

Objective To investigate the relationship between clinical presentation and pathological characteristics in HBeAg negative chronic hepatitis B(CHB) patients with steatosis, and to find out the predictors of hepatic inflammation and fibrosis. Methods HgeAg negative CHB patients with (n=56) or without (n=60) steatosis confirmed clinically and pathologically were enrolled in the study. All patients were examined for fasting blood glucose(FBG), fasting insulin (FINS), triglyceride (TG), cholesterol (TC), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyhransferase (GGT), alkaline phosphatase (ALP) albumin (Alb), globulin(Glb), homeostatic model assessment of insulin resistance (HOMA-IR), HBV-DNA and body mass index(BMI). The association of above parameters with hepatic inflammation, fibrosis and fatty deposition were analyzed statistically. Results It was demonstrated that BMI, FBG, FINS, TG, TC, GGT, ALP , Glb and HOMA-IR were significantly higher in HBeAg negative CHB patients with steatosis than those without steatosis (P<0.05). Whereas the levels of HBV-DNA, Alb, ALT and AST were significantly lower in HBeAg negative CHB patients with steatosis compared with those without steatosis (P<0.05). The hepatic inflammation and fibrosis were aggravated in patients with steatosis. It was implicated that BMI,FBG, FINS, TG, TC, GGT and HOMA-IR(all P values 0.05) were significant predictors for hepatic steatosis, while ALT, AST, Glb and HBV-DNA(all P values <0.05) were significant predictors for hepatic inflammation. And the predictors for hepatic fibrosis were ALT, AST, Alb, Glb and HBV-DNA(all P values <0.05). Conclusions Hepatic steatosis is common in HBeAg negative CHB patients which is positively associated with parameters including BMI, FBG, FINS, TG, TC, GGT, ALP and HOMA-IR. Besides steatosis, the hepatic inflammation and fibrosis are also aggravated in these patients.

Objective To investigate the expressions of insulin receptor substrate-1 (IRS-1) and insulin receptor sub-strate-2 (IRS-2) in adipocytes during catch-up growth in neonatal rats with intrauterine growth restriction (IUGR) and their correlations with the insulin resistance. Methods Sprague-Dawley rats (clean grade) were randomly divided into control group and food-restricted group after fertilization. Food-restricted group were received about 30%of food amount consumed in control group every day through the whole pregnant period to establish IUGR animal model, and were fed increased amount of breast-milk from postnatal day 1 to 21 to establish the period of catch-up growth in IUGR animal model (IUGR-CG). Fasting serum glu-cose, insulin and triglyceride were measured in blood from heart ventricles of 4-week old SD rats and insulin resistance index was calculated. Pre-adipocytes and mature adipocytes were obtained from SD rats at different age (1-week, 3-week, 5-week and 7-week old) and the former were induced to differentiate toward mature adipocytes. The levels of IRS-1, IRS-2 in the two kinds of mature adipocytes were detected by Real-Time PCR and Western blot. Results The expression levels of IRS-1, IRS-2 mRNA in mature adipocytes of IUGR-CG rats were signiifcantly lower than those of IUGR rats at 5-weeks and 7-weeks old (P<0.05) while the ex-pression levels of IRS-1, IRS-2 mRNA in differentiated adipocytes of IUGR-CG rats were signiifcantly lower than those of IUGR rats at 5-weeks old (P<0.05). The expression levels of IRS-1, IRS-2 protein in two kinds of adipocytes (mature and differentiated adipocytes) of IUGR-CG rats were signiifcantly lower than those of IUGR rats from postpartum week 1 through 7 (P<0.05). Conclusions IRS-1 and IRS-2 expression levels are downregulated in adipocytes during catch-up growth of IUGR rats, which may be closely related with insulin resistance.
