Objective To analyze the relationship between HBsAg level and HBV DNA level as well as illness severity in patients with HBV-related acute-on-chronic liver failure (ACLF).Methods One hundred and nineteen patients with chronic hepatitis B (CHB group) and 98 patients with ACLF(ACLF group) were enrolled.HBsAg and HBeAg were assayed with Roche electrochemical luminescence method.HBV DNA was quantified using a real-time polymerase chain reaction (PCR) assay.HBsAg and HBV DNA levels were compared between two groups and between HBeAg-positive and HBeAg-negative patients in ACLF group respectively,also the correlationbetween HBsAg and HBV DNA was studied.Results The proportions of HBeAg-negative patients were 68.4％(67/98) and 42.9％(51/119) in ACLF group and CHB group respectively,and there was significant difference between two groups (P ＜0.01).There was no significant difference in HBV DNA between two groups (P ＞ 0.05).HBV DNA in HBeAg-positive patients was higher than that in HBeAg-negative patients in two groups(P ＜ 0.05).There was no significant difference in HBsAg between HBeAg-positive patients and HBeAg-negative patients in ACLF group (P ＞ 0.05 ),but they were higher than that in HBeAg-positive patients in CHB group (P＜ 0.05).HBsAg was correlated to ALT,AST in HBeAg-positive patients (P ＜ 0.05).No significant correlation was found among HBsAg and HBV DNA as well as biochemical changes (P＞ 0.05).There was no significant difference in the ratio of different HBsAg levels among the patients of different HBV DNA in ACLF group (P＞ 0.05).Conclusion The level of HBsAg does not directly correlate with serum HBV DNA level,and has no directly correlation with the severity of the disease in patients with HBV-related ACLF.

Objective To study liver regeneration of the non-ligated liver lobes following portal branch ligation (PBL). Methods Sixty male Wistar rats were randomly divided into PBL group and sham operation (SO) group. Under ether anesthesia, the rats were subjected to PBL and sham operation, respectively. The animals were sacrificed on the 1st, 2nd, 3rd, 7th and 14th day respectively. The blood sample was collected from heart and the livers were harvested to determine serum alanine aminotransferase (ALT) levels and total liver weight, respectively. The hepatic histopathology was studied through light microscopy. The number of liver cell nuclear mitosis index was counted. The number of proliferative cell nuclear antigen (PCNA) index was counted by immunohistochemistry. The hepatic ultrastructural changes were studied under electron microscope. Results Elevated serum ALT level was observed in the first postoperative day in PBL group compared with SO group (P

Objective To observe the effect of rosuvastatin on vascular cell adhesion molecule-1 (VCAM -1),C-reactive protein (CRP),TG,TC and LDC in patients with acute cerebral infarction at the early stage.Methods According to the random number expression method,90 patients with acute cerebral infarction were divided into rosuvastatin treatment group and control group,with 45 cases in each group.The course of treatment was 21 days.The control group was given conventional western medicine (aspirin,mannitol etc.),the treatment group received rosuvastatin on the basis of the control group.Before and after treatment,the plasma VCAM-1,CRP,TG,TC,LDLch levels,clinical efficacy,efficacy of regulating dyslipidemia and drug safety were compared.Results After treatment,the CRP levels in the two groups were improved.After treatment for 7 days,14 days,the CRP levels of the treatment group were (23.68 ± 5.23) mg/L,(16.68 ± 6.76) mg/L,respectively,which improved more significantly than those of the control group [(30.12 ± 6.68) mg/L,(21.12 ± 6.35) mg/L],the differences were statistically significant (t =5.092,3.230,all P ＜ 0.05).After 21 days of treatment,the CRP of treatment group was better than the control group,but the difference was not statistically significant (P ＞ 0.05).The VCAM-1 levels of the two groups after treatment were improved.After treatment for 7 days,14 days,the VCAM-1 levels of the treatment group were (1 205.1 ±61.8)mg/L,(852.1 ± 60.2)mg/L,respectively,which were improved more significantly than those of the control group[(1 415.6 ± 62.9) mg/L,(963.1 ± 53.3) mg/L],there were statistically significant differences between the two groups (t =21.815,9.261,all P ＜ 0.05),21 days after treatment,there was no statistically significant difference (P ＞ 0.05).The levels of TG,TC,LDC in the two groups were all decreased after treatment for 7 days,14 days and 21 days,and the improvement in the treatment group was more obvious,the differences between the two groups were statistically significant (t =5.219,7.303,4.044,2.232,4.336,3.612,2.689,7.817,11.057,all P ＜0.05).Conclusion Compared with the conventional western medicine treatment,rosuvastatin can decrease the plasma levels of CRP,VCAM-1,TG,TC,LDC,further improve the pathological basis of ischemic cerebrovascular disease,eliminate the risk factors,it is more conducive to the prognosis of acute cerebral infarction.
