OBJECTIVE:To observe clinical efficacy and safety of triptorelin acetate in the treatment of endometriosis after lap-aroscopy. METHODS:196 cases of endometriosis were randomly divided into experimental group and control group with 98 cases in each group according to admission sequence. Both groups received laparoscopic surgery. After surgery,experimental group was given triptorelin acetate by intramuscular injection,3.75 mg/time,every 4 weeks;control group was given gestrinone orally,2.5 mg/time,twice a week,for 5 months. The ovulation,menstrual recovery and the occurrence of ADR were observed in 2 groups. The endometriosis relapse of 2 groups were followed up for 1 year and observed. RESULTS:After treatment,the ovulation recov-ery time and menstrual recovery time of experimental group were all shorter than those of control group,with statistical signifi-cance(P<0.05). The incidence of ADR in experimental group(17.34%)was significantly lower than in control group(35.71%), with statistical significance(P<0.05). During follow-up period,the relapse rate of experimental group(7.14%)was significantly lower than that of control group(18.37%),with statistical significance(P<0.05). CONCLUSIONS:After laparoscopic surgery, triptorelin acetate can significantly improve therapeutic efficacy of endometriosis,reduce the occurrence of ADR.

Objective To investigate the renoprotective effects of autologous transplantation of adipose-derived mesenchymal stem cells (ADMSCs) in diabetic rats. Methods Sprague-Dawley (SD) rats were injected intraperitoneally with 40 mg/kg streptozotocin (STZ) for 5 consecutive days to induce type 1 diabetes. Four weeks following STZ injection, eighteen SD rats were randomized into two groups: the diabetic group (n = 9) and the ADMSCs group (n = 9). Normal nondiaetic rats were set as the normal control (n = 9). Autologous ADMSCs were cultured and identified in vitro , which were intravenously injection to the ADMSCs group rats via the tail vein. At 8 weeks after transplantation, levels of blood glucose, insulin, serum urea nitrogen, serumcreatinine and urine protein were measured. Meanwhile the body weight and kidney weight were examined. Results Mesenchymal cell surface markers were expressed in the cultured ADMSCs. The ADMSCs could differentiate into the adipogenic and osteoblastic lineages. Both the diabetic group and the ADMSCs group rats had higher levels of blood glucose , urea nitrogen , serum creatinine , urine protein and higher ratio of the kidney weight/body weight than those in the normal control group (P < 0.05, respectively). Blood glucose, urea nitrogen and the ratio of kidney weight/body weight in the ADMSCs group rats were significantly decreased compared with the diabetic group (P < 0.05, respectively). The decreased insulin level was attenuated after transplantation of ADMSCs (P < 0.05). Besides, levels of serum creatinine and urine protein in the ADMSCs group were lower than those in the diabetic group with no significant difference. Conclusion Autologous transplantation of ADMSCs can improve metabolic disorder and relieves diabetic renal damage.

Objective To research the pyrazinamide drug susceptibility of Mycohacterium tuberculosis,and provide reference for clinical medication and prevention.Methods Bactec MGIT 960 system was used to test the resistance of isoniazid,rifam picin,ethambutol,streptomycin and pyrazinamide for 153 strains of Mycobacterium tuberculosis.Results Of 153 Mycobacterium tuberculosis,34 were resistant to PZA,and the resistant rate was 22.2 %.There was no PZA single drug resistance.A mong patients with and without INH resistance,RFP resistance,EMB resistance and Sm resistance,the proportions of PZA resistance were respectively 40.5 % (34/84) vs 0%(0/69),47.5%(29/61) vs 5.4%(5/92),75%(6/8) vs 19.3%(28/145),53.1% (26/49) vs 7.7% (8/104).Among the 54 multidrug-resistant (MDR) strains 53.7% were resistant to PZA,which was significantly higher than 5.1 % (5/99) among the nonMDR-TB strains (x2 =47.854,P<0.05).In multivariate logistic analysis,resistance to Sm (OR=0.270,95%CI:0.091~0.802) and MDR-TB (OR=0.281,95%CI:0.087~0.911) were risk factors to PZA resistance.Conclusion The PZA resistance rate among MDR-TB isolates was high.PZA resistance would be associated with SM resistance and MDR-TB.The drug susceptibility test for PZA is very important to MDR-TB patients.
