OBJECTIVE To realize the present resistance characteristics of enterococci to common antimicrobial agents,and to provide reference for clinical therapy. METHODS A total of 79 isolates of enterococci were collected from samples during the period of 2000-2003.The broth microdilution test and ?-lactamase determination were performed for each of the strains.The laboratory data were analyzed. RESULTS The rates of Enterococcus faecalis and E.faecium were 73.4%,and 26.6% of all enterococci isolates.The most common sites of infection were urinary tract(35.4%),surgical secretion(24.1%),and sputum(15.2%).The rate of E.faecium approached 50% of enterococci in urinary tract.The antibiotic resistance of E.faecium was more than E.faecalis to ampicillin,penicillin,and rifampin.The ratio of HLAR enterococci and VRE to total enterococci isolates were 61.9% and 0;?-lactamase producing rate was 6.3%. CONCLUSIONS Urinary infection caused by enterococci is most frequent.E.faecium is found more easily in urinary tract than in the others and very resistant to antibiotics.Vancomycin shows fairly high activity against enterococci.The different regimens should be adopted for different enterococci.

HPLC was used for the content determination of salvianolic acid B in the preparation:the column was Diamonsil C18(2)with mobile phase of acetonitrile-0.1% H3PO4(22:78, V/V) at a flow rate of 0.5 ml/min,detection wavelength was 286 nm,column temperature was 30 ℃,and the injection volume was 2 μl. RESULTS:The TLC spots of C. radix and R. glutinosa were clear and well separated;the linear range of salvianolic ac-id B was 0.0792-0.792 μg(r=0.9999);RSDs of precision,stability and reproducibility tests were lower than 1%;recovery was 100.71%-101.82%(RSD=0.50%,n=6). CONCLUSIONS:The established standard can be used for the quality control of Shuang-shen capsule.

Objective To explore the efficacy and safety of terminating biochemical pregnancy (the stage in which intrauterine or ectopic pregnancy cannot be confirmed) with mifepristone and misoprostol. Methods Mifepristone (150 mg) combined with misoprostol (600 ?g) 3 days later were given to 500 biochemical pregnancies (G_1),500 early clinical pregnancies (G_2) and 500 clinical pregnancies (G_3) which were classified according to amenorrhea days,serum human chorionic gonadotropin-beta subunit (?- hCG) and vaginal B-ultrasonic examinations.All were observed for 6 hours after taking misoprostol and returned for assessment per week.Results Expulsion of conceptus was G_1 123 (24.6%,123/500),G_2 438 (87.6%,438/500) and G_3 467 (93.4%,467/500).Failure rate was G_1 6 (1.2%,6/500),G_2 24 (4.8%,24/500) and G_3 79 (15.8%,79/500) for ongoing pregnancies,hospitalizations for suspected ectopic pregnancies and surgical intervention for heavy or long-time bleeding.Bleeding cases during the administration of mifepristone were G_1 272 (54.4%,272/500),G_2 141 (28.2%,141/500) and G_3 87 (17.4%,87/500);the mean bleeding days were G_1 (5.8?1.5),G_2 (9.0?2.9) and G_3 (14.3?5.9) days.Other side effects including abdominal pain,nausea,vomiting and diarrhea were low and light in each group,increasing with advancing gestational age.Menses recovery was 486 (97.2%,486/500),452 (90.4%,452/500) and 433 (86.6%,433/500) for each group on scheduled time.Satisfaction was 499 (99.8%,499/500),485 (97.0%,485/500) and 369 (73.8%,369/500) respectively.Conclusion Mifepristone and misoprostol in combination is as safe,and effective for termination of biochemical pregnancies as ordinary medical abortion.It does not need to wait till ectopie pregnancy is excluded.

OBJECTIVE:To observe clinical effects and safety of sequential therapy of Ginkgo biloba extract preparation for elderly acute cerebral infarction,and to evaluate its pharmacoeconomics. METHODS:Totally 98 patients with acute cerebral infarc-tion selected from neurology department of our hospital during Aug. 2014-Aug. 2015 were divided into control group and test group according to random number table,with 49 cases in each group. Both groups received routine therapy of antiplatelet aggregation, microcirculation improvement. Control group was additionally given Shuxuening injection 10 mL,ivgtt,qd,for consecutive 21 d. Test group was additionally given Shuxuening injection 10 mL,ivgtt,qd,for 7-10 d;and then given G. biloba tablet instead,1 tablet,po ,tid,for 21 d in total. Clinical efficacies of 2 groups were compared as well as ESS score,ADL score,blood flow in-dexes and blood lipid indexes before and after treatment,and adverse drug reaction. Cost-minimization analysis was used for phar-macoeconomic evaluation. RESULTS:After treatment,total response rate of control group and test groups were 87.23% and 83.33%,without statistical significance (P>0.05). Before treatment,there was no statistical significance in ESS score,ADL score,blood flow indexes and blood lipid indexes between 2 groups (P>0.05). After treatment,ESS score and ADL score of 2 groups were increased significantly,and whole blood viscosity,plasma viscosity,hematocrit,fibrinogen content,TC and TG were decreased significantly;there was statistical significance with before treatment(P<0.05);there was no statistical significance be-tween 2 groups(P>0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). The average cost of control group and test group were (7060.9 ± 234.8) yuan and (5800.7 ± 149.5) yuan,with statistical significance (P<0.01). CONCLUSIONS:The sequential therapy of G. biloba extract preparation is similar to intravenous dirpping in the treatment of elderly acute cerebral infarction in therapeutic efficacy and safety. The sequential therapy is better in economics field.
