OBJECTIVETo observe the therapeutic effect of acupuncture on gastrointestinal dysmotility in liver cirrhosis.

METHODSForty cases of gastrointestinal dysmotility in liver cirrhosis were randomized into an acupuncture group and a motilium group, 20 cases in each one. In the acupuncture group, on the basis of the conventional treatment, electroacupuncture was applied at Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3) for 30 min, once a day. In the motilium group, on the basis of the conventional treatment, motilium was taken orally 30 min before meals, 10 mg each time, three times a day. The treatment was required for 2 weeks in both groups. The changes in the digestive tract symptom score and liver function Child-Pugh score were observed and the efficacy was assessed.

RESULTSThe total effective rate of digestive tract symptoms was 85.0% (17/20) in the acupuncture group and 70.0% (14/20) in the motilium group. The score improvements in abdominal distention, belching and vomiting in the acupuncture group were superior to those in the motilium group (all P < 0.05). In the acupuncture group, the liver function Child-Pugh total score was 8.40 +/- 0.22 before treatment and reduced to 5.36 +/- 0.17 after treatment, in which the scores for ascites, serum bilirubin and albumin were all reduced (all P < 0.05) and the reducing range was increased in tendency with the improvements in digestive tract symptoms. In the motilium group, Child-Pugh score was not changed obviously as compared with that before treatment. CONCLUSION Acupuncture effectively alleviates digestive tract symptoms and improves liver function for the patients of liver cirrhosis, its efficacy on gastrointestinal dysmotility in liver cirrhosis is superior to motilium.

OBJECTIVETo observe the effect of adenovirus-mediated overexpression of AMP-activated protein kinase (AMPK) on apoptosis of hepatic stellate cell line LX2.

METHODSAfter adenovirus infection of the LX2 cells, the exogenous gene expression was detected by Western blotting, and cell apoptosis evaluated by flow cytometry with PI staining. Agarose gel electrophoresis was performed to detect the DNA ladder, and the expressions of caspase-3, Bcl-2 and Bax are detected by Western blotting.

RESULTWith AMPK overexpression, apoptotic peak and DNA ladder of the infected cells appeared, and pro-caspase-3 was activated to transform into caspase-3 accompanied by up-regulated Bax expression, whereas Bcl-2 expression was hardly detectable by Western blotting.

CONCLUSIONOverexpression of AMPK mediated by the adenovirus can induce LX2 cell apoptosis, possible as a result of up-regulated Bax expression with low Bcl-2 expression.

The serum levels of ALT, AST and the contents of HA in anluohuaqianwan group were significantly lower than those in the model group (P less than 0.01). The liver MMP-2 in the model group was significantly increased compared to that in the normal group (P less than 0.05).

OBJECTIVETo observe the protective effect of Tanreqing injection(TRQ) on carbon tetrachloride-induced acute hepatic injury in rats.

METHODRats were randomly divided into the normal group and the model group, and injected subcutaneously with 100% CCl4 5 mL x kg(-1) to establish the single CCl4 infection model, in order to observe the changes in rat liver injury after 3 h and 6 h. Subsequently, the multiple CCl4 infection liver injury model was reproduced by subcutaneously injecting 100% CCl4 (5 mL x kg(-1)), 50% CCl4 olive oil solution (2 mL x kg(-1)) and then 20% CCl4 olive oil solution (2 mL x kg(-1)). At 6 h after the first CCl4 injection, the rats were divided into six groups: the model group, the control group, the diammonium glycyrrhizinate-treated group, and TRQ high, middle and low dose groups. They were injected through caudal veins, while a normal control group was set up. Their weight and liver-body ratio were observed. Hepatic inflammation was observed with HE staining. Assay kits were adopted to detect ALT, AST, T. Bil, D. Bil, CHE, TBA, gamma-GT and Alb.

RESULTAccording to the single injection model, serum AST and T. Bil of model rats were obviously increased at 6 h after single subcutaneous injection of CCl4, with disordered lobular structure in liver tissues, notable swollen liver cells and remarkable liver injury. According to the results of the multiple injection pharmacological experiment, compared with the normal group, the model group had higher serum ALT, AST, and gamma-GT activities (P < 0. 05), TBA and T. Bil contents (P < 0.05) and lower CHE activity (P < 0.05). HE staining showed disorganized lobular structure in liver tissues and notable ballooning degeneration in liver cells. Compared with the model group, TRQ high and middle dose groups and the diammonium glycyrrhizinate-treated group showed significant charges in serum liver function and inflammation in liver cells. Specifically, TRQ high and middle dose groups were superior to the diammonium glycyrrhizinate-treated group.

CONCLUSIONTanreqing injection has significant protective effect on CCl4-induced acute hepatic injury in rats.

BACKGROUNDIn most colorectal carcinomas, the level of phospholipase C (PLC)-gamma 1 expression is greatly elevated. Increased expression of PLC-gamma 1 may play an important role in colon carcinogenesis, but the mechanism is not well known. The aim of this study was to evaluate the role of PLC-gamma 1 in colon carcinogenesis by using recombinant lentivirus that stably suppressed the PLC-gamma 1 expression in human colorectal carcinoma LoVo cells.

METHODSRecombinant lentivirus producing PLC-gamma 1 siRNA were prepared. After LoVo cells were transduced by each lentivirus, stably transduced cells were selected by Blasticidin. The protein and mRNA expression of PLC-gamma 1 were examined by Western-blot and reverse transcription-polymerase chain reaction (RT-PCR) analysis, and the effects of the lentivirus on the cell adhesion, migration and apoptosis were analyzed.

RESULTSStable LoVo cell line deficient in PLC-gamma 1, was established. Notably, PLC-gamma 1 was silenced without affecting the levels of other subtypes of PLC so that the role of PLC-gamma 1 in colon carcinogenesis could be examined. Silencing of endogenous PLC-gamma 1 resulted in efficient inhibition of the adhesion and migration of LoVo cells in vitro and a great increase of 5-fluorouracil induced apoptosis (30%-40%) of LoVo cells.

CONCLUSIONSPLC-gamma 1 may play an important role in metastasis and anti-apoptosis in human colorectal carcinomas.
