Objective To study the intestinal bacterial overgrowth(IBO)and bacterial translocation(BT)in cirrhotic rats,and the effect of microecologics on it.Methods In order to induce cirrhosis model the rats were given 40%CCl4 elaeo-solution by subcutaneous injection,then were treated by microecologics(prebiotics and probiotics).The rats were randomly divided into normal control group(13 rats),cirrhosis model group(10 rats),prebiotics therapy group(19 rats),probiotics therapy group(19 rats)and therapy control group(20 rats).To detect endotoxin,cultivate and count enteric bacilli.mesenteric lymph nodes,tissue of liver and spleen were taken to cultivate bacteria.Results ① the counts of small intestinal bacilli in cirrhosis rats were obviously higher than normal rats(P

Objective To explore the clinical character istics of bile reflux gastritis. Methods We observed 1328 patients with bile reflux gastritis(excluding gastritis of the remnant stomach),and selected 425 superficial gastritis as control group.All the patients took helicobacter pylori(Hp) rapid urease examination. 664 cases in observed group and all in patients of control group were examined for bile disease by UB. Results In 1328 patients,there were 797 male and 531 female,and the ratio of male and female was 1.5/1.The detecting rate of bile reflux gastritis was decreased along with aging. Among all the patients,there were 651 simple superficial gastritis(49%),86 gastric ulcer(6.5%),412 duodenal ulcer (31%),122 combined ulcer(9.2%) and 57 other disease(4.7%).In observed group,1030 HP(77.56%) were regative; 298 Hp(22.44%) were positive,and in control group,282 Hp(66.35%) were regative,147 Hp(33.65%) were positive.The amount of gallbladder disease resection was 221(33.3%),which was more than that of control group(16.9%). Conclusion The detecting rate of bile reflux gastritis was decreased along with aging.Bile reflux gastritis is more often combined with ulcer disease or gallbladder disease. The Hp infection rate of bile reflux gastritis is significant lower than that of non-bile reflux gastritis.

This study aims to compare the urate-lowering response rate of febuxostat and allopurinol in gout patient using a model-based meta-analysis. The literature search identified 22 clinical trials of gout with a total of 43 unique treatment arms that met our inclusion criteria, and a total of 6 365 gout patients were included in the study. The response rates of allopuriol and febuxostat were characterized by Tmax model and Emax model respectively, and the effect of baseline serum uric acid (sUA) and patient type on the drug effect was tested. The results showed that allopurinol can reach an average maximum response rate of 50.8% while febuxostat can reach a 100% response rate within a very short time, and the ED50 was 34.3 mg. Covariate analysis revealed that baseline sUA has a negative effect on response rate of allopurinol, and a positive effect on the predicted ED50 of febuxostat. For patients who had shown inadequate response to prior allopurinol treatment, the average response rate was about half that of the allopurinol responder patients.
