Objective To evaluate the effects of probiotics on experimental colitis of rats and to explore systemic and local changes of T regulatory cells(Tr) after the treatment. Methods The models of experimental colitis were established by enema with 2,4,6-trinitrobenzenesulphonic acid (TNBS). Live probiotics of combined bifidobacterium,lactobacillus and enterococcus (Bifico) were used. Four groups of rats were set up as negative group, TNBS alone group, probiotics group (high dosage and low dosage, with dose of 150 and 300 mg?kg-1?d-1, respectively), and combination group (probiotics plus prednisolone or sulfasalazine). Histologic scoring was used to evaluate the effect of medications; the proportions of CD4+CD25+ and CD8+CD28- Tr in peripheral blood, spleen mononuclear cells and intraepithelial lymphocytes of colon were detected by flow cytometry. Results Histopathology showed that high dosage of probiotics was effective in TNBS-induced colitis rats (2. 2?0.8 vs 3.5?0.7,P

Objective To evaluate the effects of probiotics in experimental colitis of rats.Methods Models of experimental colitis were established.Several groups of rats were set up as probiotics group,negative group and positive group.Histologic scoring was used to estimate effects of drugs;the expression of CD~+_4 andCD~+_8 on T cell surface in peripheral blood,spleen mononuclear cells and intraepithelial lymphocytes of colon were detected by flow cytometry.Results Histopathology shows that probiotics of larger dosage was curative for experimental colitis in rats.Proportion of CD~+_4 and CD~+_8 T cells increased in colon of colitis,which was decreased by treatment of larger dose of probiotics.CD~+_4/CD~+_8 ratio and T cell subsets in systemic immune system were not influenced by probiotics.Conclusion Probiotics of large dosage are effective in the treatment of experimental colitis of rats incuced by TNBS,possibly associated with immune regulation and tends to be localized in mucosal immune system in colon.

Objective:To observe the curative effect of vinpocetine combined with Danhong injections in the treatment of posterior circulation ischemia syndrome. Methods:Totally 120 patients with posterior circulation ischemia syndrome were selected and randomly divided into the treatment group and the control group with 60 cases in each. Both groups were treated by the conventional therapy, meanwhile, the treatment group was given vinpocetine and Danhong injections, and the control group was given vinpocetine alone. The treatment course was 14 days. The curative effect was observed, blood rheology and hemodynamics were also studied. Results:The to-tal effective rate of the treatment group was 95. 0%, which was significantly higher than that of the control group (75. 0%) with statis-tically significant difference(P<0. 05). After the treatment, the blood rheology (viscosity, low shear viscosity, plasma viscosity and reduced viscosity) and TCD ( LVA, RVA, BA and PI) in the two groups were significantly improved, and the treatment group showed more significant improvement(P<0. 05). Conclusion:Vinpocetine combined with Danhong injections in the treatment of posterior cir-culation ischemia syndrome has significant effect in the effective improvement of blood rheology and hemodynamics, which is worthy of clinical promotion and application.

Objective To find out the influencing behavioral factors of antibiotics usage in population in Lanzhou. Methods Status of antibiotics usage was investigated in four hospitals in Lanzhou. Results The self-medicine pro portion among patients with respiratory system infection, infectious di arrhea, urinary system infection and choleic system infection were 44.22%, 31. 76%, 22.07% and 6.61% respectively. Patients having higher income used some antibiotics at a middle price, while patients having lower income used antibiot ics at a lower price. The educate d person applied some antibiotics at a lower price, but the illiterate person us ed some antibiotics at a higher price. The combined usage of antibio tics was affected by the disease program and distance of seeing doctor. The fart her distance away from hospital, the more proportion of antibiotics(two or thre e) used combinedly. Conclusions The antibiotics usage was affe cted by the disease variety, disease program, distance to hospital, average inco me and educ ated level.
