Objective To explore the pathogenesis, pathomorphology, diagnosis and management of cholecystoduodenal fistula(CDF). Methods Clinical data of 11 cases of CDF admitted in our hospital in recent 17 years were analyzed retrospectively. Results All the patients were confirmed and treated by operation.Ten CDF were caused by cholecystitis and cholelithiasis,another one was caused by peptic ulcer.Only one case of CDF was diagnosed before operation. Nine patients were cured, and two patients died of severity infection of abdomen postoperatively. Conclusions Most CDF are caused by cholecystitis and cholelithiasis. X-ray film of abdomen,barium meal examination and endoscopic retrograde cholangiopancreatography(ERCP) are more useful for the diagnosis of CDF. The therapeutic principle of CDF is cholecystectomy,removing calculus, and repairing fistula with or without common bile duct exploration and/or bilioenterostomy.

Objective To observe the effects of Shenfu injection on intestinal mucosal barrier of rats with hepatic ischemia-reperfusion.Method Ninety SD male rats and weight from 230 to 270g were randomly divided into three groups( 30 rats in each),and 30 rats in each group divided again into 6h and 12h group( 15 rats in each):(1)SO group received sham operation(SO);(2) IR + NS group received so and 0.9 normal saline intravenously imediately before the ischemia reperfusion injury;(3) IR + SF group received Shenfu injection intravenously imediately before the ischemia reperfusion injury,IR + NS group and IR + SF group occlusion of the hepatoduodenal ligament,and endotoxin,ALT and MDA were detected.Results The levels of ALT,MDA in IR + NS group were higher than those in IR + SF group,and the rate of bacterial translocation( BT)group.

Objective To construct the vector that expresses the fusion protein of HIV-Tat protein and red fluorescent protein(mCherry) in mammalian cells,and observe by fluorescence microscopy the intracellular transduction and localization of recombinant protein in cells,in order to obtain a useful tool for the study of the uptake mechanism and intracellular localization of HIV-TAT.Methods With the designed primer coding mCherry sequence,the mCherry gene was amplified by PCR with the vector pmCherry-C2 as template,and inserted into vector pET14b-His-TAT to construct the expression vector pET14b-His-TAT-mCherry.The constructed vector was then transformed into E.coli BL21(DE3),which had been identified by PCR and double digested with restriction endonuclease,followed by sequencing.After IPTG induction,the recombinant protein of His-TAT-mCherry was lyzed and analyzed with SDS-PAGE.Purified His-TAT-mCherry recombinant protein was added to Hela cells and the fluorescence was observed to evaluate the transduction efficiency.Results The results of identification by PCR,digestion with restriction endonuclease and sequencing indicated that the vector His-TAT-mCherry was correctly constructed.His-TAT-mCherry fusion protein was expressed in mammalian Hela cell line and purified successfully,and the fusion protein showed cellular transduction activity.It was found by fluorescence microscopy that the red fluorescence protein located mainly over the cytoplasm,and also the membrane to some extent.Conclusion The expression vector is successfully constructed for HIV-TAT labeled with mCherry sequence.Effective expression and purification of this fusion protein is achieved.It has been observed that the constructed vector may be expressed in mammalian Hela cell under active condition.Thus,it might be useful in the study of uptake mechanism and intracellular localization of HIV-TAT.

OBJECTIVE To analyze the situation of extended spectrum ?-lactamases(ESBLs)and AmpC enzyme produced by nosocomial Escherichia coli isolates in 2005-2007.METHODS ESBLs were detected by double disk synergy test and disk diffusion confirmatory test.AmpC enzyme was detected by the three dimensional assay.Chi square test was used to test the significance.The application of different kinds of antimicrobials before the results of etiology be presented and the resistence rate of the ESBLs both producing and no producing were compared respectively.RESULTS The detectable rate of ESBLs in E.coli isolates of nosocomial and community infection was 55.1% and 21.3% and the detectable rate of AmpC enzyme nosocomial E.coli isolates was 17.4%.All strains were 100% susceptible to meropenem and imipenem but resistant to 15 other antimicrobials in different degree.The sensitivity to Piperacillin/tazobactam,cefoperazone/sulbactam and amikacin were relatively high.CONCLUSIONS The carrying rate of ESBLs from nosocomial E.coli isolates is high and AmpC enzyme and other resistance genes,which lead to multiple drug resistance.Standardized management of antimicrobials application should be strengthened and the consciousness of rational antimicrobials utilization should be raised.

OBJECTIVE:To observe the effect of ulinastatin on the serum inflammatory cytokines of patients with ulcerative colitis. METHODS:Totally 60 patients with ulcerative colitis were randomly divided into observation group and test group,and an-other 20 healthy volunteers were selected as normal control group. Test group were received routine treatment,including nutrition support and maintaining water,electrolyte balance and 5-amino salicylic acid (5-ASA),etc. Patients in observation group were treated by ulinastatin 200 000 U by intravenous infusion based on the treatment of test group,q12h. 7 d were as a course for the pa-tients,and it lasted for 2 courses. The clinical data in healthy control group and other 2 groups was observed,including tumor ne-crosis factor-α(TNF-α),interleukin-1β(IL-1β),IL-8,C-reactive protein(CRP)levels,colon peroxidase activity(MPO),clinical activity index(CAI)scores and the incidence of adverse reactions before and after treatment. RESULTS:Before and after treatment, the TNF-α,IL-1β,IL-8,CRP and MPO in other 2 groups were significantly higher than health control group,with significant dif-ferences(P<0.05). After treatment,the TNF-α and IL-1β in 2 groups and the IL-8 and CRP levels in observation group were low than before,and the TNF-α,IL-8 and CRP levels in observation group were significantly lower than test group,with significant dif-ferences(P<0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Based on the routine treatment, ulinastatin can effectively inhibit the expression of inflammatory cytokines of patients with ulcerative colitis,and relieve the inflam-mation and injury of colon,with good safety.

AIM: To establish the quality standard for Huanglongganzhixiao Granule(Resina Draconis, Radix Astragali, Herba Epimedii, etc.). METHODS: Radix Astragali, Resina Draconis, Herba Epimedii in Huanglongganzhixiao Granule were identified by TLC. The content of loureirin B in this Granule was determined by HPLC. RESULTS: Radix Astragali, Resina Draconis, Herba Epimedii could be identified by TLC. Loureirin B showed a good linear relationship at a range of 0.032～0.096?g, r =0.9997( n =5). The average recovery was 100.1% and RSD was 3.33%. CONCLUSION: The method is simple, accurate and with strong specificity and can be used for the quality control of Huanglongganzhixiao Granule.

A rat model of laryngeal allotransplantation was established by employing an end- to-side anastomosis of donor bilateral common carotid arteries to recipient common carotid artery and external jugular vein separatively.Thirteen allotransplants were performed in 26 SD rats.All recipients survived.Three days after the operation,a visible fibrinous adherence was observed around the laryngeal grafts.By the 7th day,the adherence became intensified.The airway was plugged with mucoid material,and the viable grafts were surrounded by connective tissues.Our results confirmed that the rat model was practicable for laryngeal allograft.Besides the difference of the major histocompatibility between the donor and recipient,the skill of microsurgery,the prevention of infections and the methods of donor organ flushing are all vital to a successful trans- plantation.
