ObjectiveTo investigate the expression and clinical significance of CD40 in the spleen of cirrhotic portal hypertension. MethodsExpression of CD40 was determined with S-P immunohistochemistry in spleen specimens from 50 cases of cirrhotic portal hypertension and 15 healthy individuals. ResultsThe CD40 positive rates in normal spleen and cirrhotic spleen were 86.7% and 36.0%, respectively. There was a significant difference between the 2 groups (P＜0.05). There was a negative correlation between the expression of CD40 and Child grades of liver function and cirrhotic splenic types(P＜0. 05). Conclusion CD40 might reflect the changes of splenic immune function,which might be one of more exact clinical examination indexes of splenic immune function.

Objective To evaluate the sensitivity and specificity of histopathologie analysis vs cytomegalovirus (CMV) detection for the diagnosis of CMV-infected hepatitis post liver transplantation. Methods Twenty-five biopsies with CMV infection and twenty-five without CMV infection were collected. Histopathologic observation, immunohistochemical staining and virus detection were performed on both groups to evaluate the sensitivity and specificity of these examinations for the diagnosis of CMV-infected hepatitis. Results The detection rate of microabscess, aggregation of monocyte and rnacrophage, and cytomegalic change in CMV infection group was higher than that in the group without CMV infection (P<0.05), but there was no significant difference in intranuclear inclusion and eosinophilic body between the two groups (P>0.05). The sensitivity and specificity of IHC and PCR for CMV detection were 20% and 100%, 72% and 84%, respectively. Conclosions CMV detection with PCR combined with histological observation is the most effective diagnostic scheme for CMV disease of liver.

Objective To investigate the expression of Muc1,Muc3A and Muc4 in cultured intrahepatic bile duct(IBD)tissues from different hepatic segments after cold preservation.Methods The IBD tissues of SD rats were obtained by collagen perfusion combining mechanical separation and then were divided into large and small IBD.The 2 parts of IBD were seeded in rat tail collagen gel and were cultured for 48 hours,then the IBD tissues from 10 rats were stored in UW solution at 4℃ for 1 hour(group I,n=5)and 12 hours(group Ⅱ,n=5),respectively,and the IBD tissues from the rest 5 rats were cultured in incubator at 37℃ for 24 hours (control group,n=5).The expressions of Muc1,Muc3A and Muc4 were detected by RT-PCR and Western blot.All data were analysed via ANOVA or LSD test.Results The expressions of Muc1,Muc3 A and Muc4 were detected both in large and small IBD tissues.The mRNA expressions of Muc1,Muc3A and Muc4 were decreased in large IBD as time passed by,which were 0.95±0.14,0.26±0.04 and 0.24±0.06 in group Ⅰ,0.18±0.03,0.14±0.04 and 0.22±0.07 in group Ⅱ,1.00±0.20,1.00±0.09 and 1.00±0.21 in control group,with significant difference among the 3 groups(F=8.8,57.1,10.8,P＜0.05).The mRNA expressions of Muc1 and Muc3A in group Ⅱ were significantly lower than in group Ⅰ(P＜0.05).The protein expressions of Muc1 and Mue3A in large IBD were also decreased as time passed by,which were 0.82±0.13,0.73±0.10 in group Ⅰ,0.56±0.11,0.33±0.04 in group Ⅱ,1.05±0.41,1.06±0.38 in control group,with significant difference among the 3 groups(F=3.9,12.6,P＜0.05).The protein expression of Muc1 of group Ⅱ was significantly lower than in control group(P＜0.05),and the protein expression of Muc4 in group Ⅱ was significantly lower than in group Ⅰ(P＜0.05).The mRNA expressions of Muc3A in small IBD were increased as time passed by,which were 0.15±0.04 in group Ⅰ,0.19±0.05 in group Ⅱ and 0.06±0.03 in control group.Conclusion Decreases of Muc1,Muc3A and Muc4 in IBD after long time cold preservation may weaken the selfprotection of biliary epithelium and case sever injury to bile duct.

Objective To establish a stable orthotopic liver transplantation(OLT)model with hepatic artery reconstruction in mice.Methods Of the 66 OLT mice,33 recipient mice underwent conventional 'two cuff' technique without hepatic artery reconstruction(control group),33 with hepatic artery reconstruction using 'stent' technology(experimental group).Results The 2 week posttransplant survival rate was 84.85%(28/33)and 81.82%(27/33)in the arterialized and nonarterialized groups respectively.Serum γ-GT and ALP level of arterialized recipient were much lower than those of nonarterialized animals.The pathology of the donor liver showed that rearterialization helps to relieve bile duct injury of liver allograft.Conclusions The hepatic artery supply plays a central role in preventing bile duct injury after transplantation.This mouse OLT model may meet the need for the study of problems associated with liver transplantation.

OBJECTIVETo study the clinical effects of Fuzheng Huayu Gantang comprehensive therapeutic program (FHGP) on post-hepatitis B liver cirrhosis associated with glyco-metabolic abnormality (LCGA).

METHODSThe patients with LCGA enrolled in the randomized controlled clinical trial were assigned to 2 groups, the treated group (68 cases) and the control group (74 cases), they were treated respectively by FHGP and conventional TCM and Western medicine therapeutic program for 3 months. Indexes including fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PG), fasting insulin (FINS) were detected, homeostasis model assessment insulin resistance (HOMA-IR) was calculated, and the score of syndrome was recorded before and after treatment. Then the effects on syndrome and glyco-metabolic abnormality were evaluated through statistical analysis.

RESULTSLevel of 2 h PG after treatment was lowered in both groups (P < 0.01), but significant difference was found in the pre-treatment to post-treatment decrement of FPG and HOMA-IR between the two groups (P < 0.05). The syndrome improving rate and the total effective rate on glyco-metabolic abnormality in the treated group were significantly better than those in the control group respectively (85.3% vs 64.9% , P < 0.01; 80.9% vs 62.2%, P < 0.05).

CONCLUSIONFHGP has the capability to improve the syndrome and glyco-metabolic abnormality of patients with LCGA.
