Objective:To evaluate the efficacy and safety of rifaximin against acute bacterial diarrhea.Methods:The effect of rifaximin for the treatment of acute bacterial diarrhea was investigated in a randomized,single-blind clinical trial with control of ciprofloxacin.Patients were administered with rifaximin 0.4g tid on the first day,followed by 0.4g bid;as for ciprofloxacin 0.25g tid on the first day,followed by 0.25g bid,until the end of 3～7days treatment,respectively.Stool,blood(hepatic and renal functions),urine samples and ECG of pre-and post-treatment were assayed for safety evaluation of rifaximin in diarrhea patients.Results:29 patients in rifaximin group and 25 in ciprofloxacin group showed similar efficacy rates and recovery rates, 100% and 91.3% respectively.There was no statistic difference between the two groups related to the effectiveness.The bacterium positive rate was 64.8%(35/54)before treatment.Bacterial clearance rates were 100% and 87.5%.No statistic difference and obvious side effect in the two groups were observed.Conclusion:rifaximin is safe and effective in the treatment of acute bacterial diarrhea.

OBJECTIVE:To compare the relative bioavailability between2loratadine tablets(LORAX and LORAS)in human body.METHODS:22healthy male volunteers were enrolled to receive oral single dose(20mg)of either LORAX or LORAS tablets by crossover way,plasma concentrations of loratadine were determined by HPLC and pharmacokinetic param-eters were calculated by3p97program.RESULTS:The pharmacokinetic parameters of LORAX vs.LORAS were the fol-lowing,t 1/2Ke (3.03?0.98)h vs.(2.65?0.81)h;C max (8.59?6.70)vs.(9.59?8.22)ng/ml;t max (1.08?0.41)h vs.(1.21?0.28)h;AUC (0～t) (27.29?24.54)vs.(27.92?20.64)(ng?h)/ml.The relative bioavailability of LORAX was(100.63?14.27)%.CONCLUSION:2loratadine tablets were bioequivalent.

Objective To observe the dynamic changes of aspartate transaminase(AST ) in gingival crevicular fluid on tooth movement in new bone area after distraction osteogenesis at different time .Methods The distraction osteogenesis surgical proce‐dure was performed in 8 beagle dogs without periodontal disease and normal teeth ,experimental teeth were transplanted into the bone regeneration area after 2 weeks and after 6 weeks .Comparative analysis AST of each time (1 ,2 ,3 ,7 ,14 ,28 d after distraction) dynamic changes in gingival crevicular fluid .Results The AST level of gingival crevicular fluid in experimental tooth was rising for the first three days ,and the group of two weeks were significantly higher than 6 weeks ;AST levels after 7 d showed a trend of de‐cline ,down to the lowest point at 21 d ,and gradually restored ,AST levels reached a higher level again in the 28 d .Conclusion The AST level of experimental teeth increased significantly after 2 weeks than after 6 weeks ,but over time the AST level change is not linear ,this change has certain guiding significance for the clinical research in the future .

Objective To study the application of problem-based learning in combination with simulating teaching in clinical probation of gynecology and obstetrics. Methods The patten of problem-based learning in combination with simulating teaching was applied to experimental group,and the traditional teaching pattern to control group. The teaching effects were evaluated by evaluation of teacher,questionnaire after class and examination. Results Satisfaction ratio of experimental group was significantly higher than that of control group in questionnaire after class. The fine ratio of experimental group was significantly higher than that of control group in written history and case analysis; but there was no significance in excellence ratio and pass ratio. There was no significance in pass ratio ,fine ratio and excellence ratio of finals between them. Conclusion The application of problem-based learning in combination with simulating teaching in clinical probation of gynecology and obstetrics can develop students'ability to practice and improve the quality of class teaching.

Objective:To quantitively detect TfR gene expression of human white blood cell before and after iron supplementation. Methods:Before and after iron supplementation,10 healthy women were phlebotomized separately,and the real-time fluorescence quantitative PCR method was used to analyze the expression difference of TfR gene in human white blood cell. Results:TfR gene expression decreased after iron supplementation in 10 women,more evidently in 7 cases,where the expression level was half less than before iron supplementation. Conclusion:TfR gene expression of human white blood cell could be quantitatively measured by FQ-PCR,and was decreased after iron supplementation in 10 women. It explained that the regulative mechanism of TfR mRNA expression by iron is also suitable to white blood cell.

OBJECTIVE To reduce or avoid the risk factors of idiopathic sudden hearing loss in Qinghai. METHODS The clinical data of 143 sudden hearing loss patients was analyzed in Qinghai by the questionnaire. RESULTS The high incidence of sudden hearing loss happened at 2 to 6 hours after waking up in the morning. And most of the patients occurred at 18～50 years old(accounted 70.63%). 79.65% of the patients were mental laborers, 57.34% were drinkers, and 59.44% were very tired before illness. There were significant differences(P
