OBJECTIVE:To introduce the research progress of biliary tract prosthesis,to analyze the reason of complication following stent implantation,and to explore the biocompatibility of various biliary tracts and host. METHODS:We retrieved Medline database (1989/2009) and CNKI (1989/2009) using the computer. According to inclusion and exclusion criteria,the literatures were screened by the first author,and the data were collected,and the quality was evaluated. We described and arranged the treatment progress of biliary tract prosthesis implantation,complication of stent implantation and biocompatibility of biliary tract prosthesis to investigate treatment state,complication and biocompatibility of the biliary tract prosthesis. RESULTS:The literatures were summarized. The bilitary tract prosthesis contains plastic stent,mental stent,silica gel tract stent and degradable polylactic acid stent. The complications of stent implantation included transudation,hemorrhage,perforation and stenosis. Among various stents,the biocompatibility of plastic stent was poor,easy to be blocked,but the price was low,and easy to be taken out. The diameter of mental stent following distension could reach 7-10 mm,with long unobstructed time,but the price was higher compared with the plastic stent. The biocompatibility of silica gel tract stent was good. The silica gel tract had strong decay resistance and pliable texture,which could extend tumor excision range and elevate curative effects. Moreover,complications did not occur such as infection and stenosis of the biliary tract. Biocompatibility of nickel-titanium alloy biliary ducts was significantly better than the stent products,without complications. With the exception of price factor,the biocompatibility of degradable polylactic acid stent was the best,but further studies were needed to observe and study the formation of biliary sludge,stent displacement and blockage,stent degradation products. CONCLUSION:Biliary tract prosthesis implantation can be an important treatment method for stenosis of biliary tract. During treatment,enough preparation is needed prior to implantation according to various clinical symptoms to select suitable stent type. Indications are followed strictly to avoid the occurrence of complications. The biocompatibility of silica gel stent and Ni-Ti alloy stent is good,but the biocompatibility of other stents should be enhanced.

Ras/Raf/MEK/ERK singal transduction plays an important role in cell proliferation, differentiation, apoptosis, metastasis and metabolism. This investigation focused on this signal pathway and chose farnesyl transferase (FTase) as the main target and Raf-1 kinase as the second target. A lot of compounds were selected to construct the pharmacophore models of farnesyl transferase inhibitors (FTIs) and Raf-1 kinase inhibitors by using computer-aided drug design (CADD). The pharmacophore of FTIs is constituted by a hydrogen bonding acceptor, an aromatic ring, a positive ionizable and two hydrophobic regions; the pharmacophore of Raf-1 kinase is constituted by a hydrogen donor, a hydrogen acceptor, a hydrophobic regions and an aromatic ring. There are some similarities between the two pharmacophores. After analysis of the constructions of these two pharmacophores, some new aminomethylbenzoic acid derivatives with good forecasting activity against both of FTase and Raf-1 kinase were designed with these new pharmacophore models.

Based on ninety three acetylcholinesterase inhibitors (AChEIs) which have the same mechanism of action but are different in structural characteristics, the pharmacophore model for acetylcholinesterase inhibitor was constructed by the CATALYST system. The optimal pharmacophore model with three hydrophobic units, a ring aromatic unit and a hydrogen-bond acceptor unit were confirmed (Weight=3.29, RMS=0.53, total cost-null cost=62.75, Correl=0.93, Config=19.05). This pharmacophore model will act on the double active site of acetylcholinesterase and is able to predict the activity of known acetylcholinesterase inhibitors that are used for clinical treatment of Alzheimer's disease (AD), and can be further used to identify structurally diverse compounds that have higher activity treating with Alzheimer's disease (AD) by virtual screening.

This retrospective analysis showed that the most frequent pathogen causing bacterial liver abscess was Klebsiella pneumoniae in 138 patients.Compared with the patients without diabetes mellitus,it was found that:( 1 ) the percentage of diabetic patients having typical abdominal pain was lower ( P ＜ 0.05 ) ; ( 2 ) neutrophilic granulocytosis was more marked,but albumin and hemoglobin levels were lower in diabetic patients( P＜0.05 ) ; ( 3 )more diabetic patients were complicated with urinary tract infection and suffered from septicemia( P＜0.05 ) ; (4) the clinical course of treatment in diabetic patients was much more prolonged( P＜0.05 ).
