Intestinal trefoil factor(IFF) is a low molecular weight polypeptide expressed in intestine.With the research on its structure and physiological function,ITF is beginning to attract attention.This review is mainly about the structure,localization,function,mechanism of action,expression regulation,signal transduction pathway,recombinant expression and so on.

Vascular or endoluminal stent is a stent implanted in the lesion site to support stenosis vessels based on luminal balloon expansion,to reduce vascular elasticity recoil and remoulding,and maintain blood flow patent.Some stents can also prevent vascular restenosis.Stent size,surface coverage,radial supporting,extensibility,longitudinal recoil,fatigue test,material composition,corrosion-resistance,coagulation,surface roughness and biocompatibility(blood compatibility) are performance parameters to evaluate the stents.Vascular or endoluminal stent has been widely used in arterial and venous systems and non-vessel luminal systems.The incidence of complications following stenting is 11.6%,including acute or subacute thrombogenesis,restenosis,or stent dislocation.It is commonly demonstrated that intrastent restenosis is caused by hyperblastosis.

OBJECTIVE: To provide a method for the microbial limit test of Anshenning oral liquid and carry out validation of the mothed. METHODS: The validation on the microbial limit test method was conducted in accordance with the counting method of bacteria, mycetes and yeasts and the control bacteria test method stated in the Appendix of China Pharmacopoeia(2010 edition). Culture dilution method was used in bacterium count and total combined molds and yeasts count; while routine method was used in the control bacteria test. RESULTS: The recoveries of test organisms in the control group 3 preparations by routine method were more than 70%. The recoveries of the test group were more than 70%. In the 3 control bacteria tests the negative control bacterias, was not found in the negative control group, while the control bacteria was found in the test group. CONCLUSION: The established method substances can eliminate the antimicrobial in Anshenning oral liquid is accurate, and comprehensive, and can be used for the microbial limit test of Anshenning oral liquid.

Objective To study the diagnostic value of MRCP in cholangiocarcinoma.Methods MRCP in 39 patients with cholangiocarcinoma comfirmed by surgery and pathology were performed on a GE 1.5T superconductive MR imaging unit before operations.Results MRCP imagings with diagnostic value were obtained in 39 cases,MRCP accurately showed the obstructive positions confirmed by surgery and pathology in all cases (100%).The qualitative rate of cholangiocarcinoma was 97%(38/39).Conclusion MRCP can not only accurately show the position of cholangiocarcinoma but also make accuracy diagnosis.

In recent years,more and more researchers have realized the possibility that algicidal bacteria could be a useful tool in reducing the impact of harmful algae blooms. In this review, the ecological roles of algicidal substances was briefly discussed, then special emphasis placed on the categories and extract methods of algicidal substances which have been reported. Some ideas for the further studies on algicidal substances were also proposed.

Objective To Discuss the causes,prevention and treatment of delayed bile leakage following laparoscopic cholecystectomy (LC). Methods From November 1994 to December 2007,totally 11 000 cases of LC were performed in our hospital,12 of them developed delayed bile leakage after the procedure. The mechanism,characteristics,treatment,and prognosis of the disease were analyzed retrospectively. Results Among the twelve cases of delayed bile leakage,eight cases showed perforation of the bile duct caused by thermoelectric effect,two cases had leakage of the aberrant bile-duct,and two cases were injured by unknown reasons. B-ultrasonography-guided drainage was performed in four of the patients,laparoscopic or open repair combined with T-tube drainage were carried out in three,abdominal puncture combined with endoscopic nasobiliary drainage (ENBD) was done in three,abdominal puncture with endoscopic retrograde biliary drainage (ERBD) was made in one,and open repair and bilio-jejunal anastomosis was performed in one. All patients were cured and discharged in 8 to 21 days with a mean of 15 days. No intra-abdominal infection,hemorrhage,recurrent bile leakage or intestinal leakage occurred after the operations. Re-examination by B-ultrasonography or cholangiopancreatography performed ten days after the drainage showed no stricture or dilation of the bile duct,and contrast media drained out fluently. The 12 cases were followed up for one year,none of them showed biliary stenosis or infections during the period. Conclusions Post-LC injury of the bile duct is mostly caused by thermoelectric effect. Gentle operation and separation strictly following the anatomical levels are the keys in prevention of postoperative delayed bile leakage; while endoscopy and interventional treatment are main methods for the diagnosis and treatment of the disease.

The basic physiological function of anti-arrhythmic drugs is affects myocardial cell membrane ion channels. Change the ion flow and affect cell electrophysiological properties, change the conduction velocity, eliminate retrace, inhibit autorhythmicity and trigger events, inhibit the occurrence of arrhythmia, but will trigger a new activities, new retrace, produce new arrhythmia. In recent years, with the improvement of the theoretical system of traditional Chinese medicine and the production of new research methods, Chinese medicine treatment of arrhythmia has a new development. This article summarized the recent decades of which Chinese medicine monomer anti-arrhythmic drugs that had been proved by the influence of monomer anti-arrhythmic drugs, lists the differents traditional Chinese medicinal materials which chemical composition and the effective of the anti-arrhythmic effects, shows the unique advantages of Chinese medicine in the aspect of anti-arrhythmic, and points out that the current Chinese medicine in anti-arrhythmic (monomer) existing problems and solutions.

Objective To investigate the genes differentially expressed in prostate cancer and to determine some prostate cancer associated genes for diagnosis and treatment prostate cancer. Methods cDNA microarray chips containing 4 366 human genes in full length were used to investigate the differential gene expression patterns of samples from human prostatie cancers and normal prostate tissues. Results A total of 287 genes differentially expressed with prostatie cancers and normal prostate were screened out,comprising 165 unknown genes and 122 known genes.Among the known genes we further identified 56 genes which were markedly differentially expressed (20 up-regulated and 36 down-regulated genes). Conclusions cDNA microarray chips for analysis of genes expression patterns is a powerful method for identification of novel prostatie cancer associated genes.
