Objective To explore the clinical effect of ozone combined with nifuratel nystatin vaginal soft capsules on the treatment of vaginitis, and to provide the basis for clinical application. Methods 204 patients with vaginitis in our hospital from January 2013 to December 2016 were divided into the observation group (114 cases) and the control group (90 cases) according to the different treatment methods. The control group was treated with nifuratel nystatin vaginal soft capsules, and the observation group was treated with ozone combined with nifuratel nystatin vaginal soft capsules. The clinical efficacy, symptom relief time and adverse reaction were compared between the two groups. Results After treatment, the total effective rate in the observation was 97.37%, which was significantly higher than 85.56% in the control group(P<0.05). The rapid remission rate of the clinical symptoms in the observation group was significantly higher than that in the control group (P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups.Conclusion The effect is significant that ozone combined with nifuratel nystatin vaginal soft capsules is used on the treatment of vaginitis, which can quickly relieve symptoms, and will not significantly increase the adverse reactions, is worthy of application.

Objective To explore the expression of HIF-2? and VEGF in renal cell carcinoma (RCC) and their correlation with angiogenesis and metastasis of renal cell carcinoma. Methods Expression of HIF-2? and VEGF were assessed by immunohistochemical straining in 48 cases of renal cell carcinomas. Results In 48 cases of renal cell carcinomas, positive rate of HIF-2? was 70.8%. Strong expression of HIF-2? was observed in 12 cases, moderate in 10 cases, weak in 12 cases and no expression in 14cases.There was a significant difference in HIF-2? expression between carcinoma tissues and control tissues (P

Objective To develop a HPLC-MS/MS method for determination of Tacrolimus(FK506) in bone marrow trans plant patient,and explore the relationship of HPLC-MS/MS with CMIA and Elecsys in the measurement of FK506 blood drug concentration,and provide reliable basis for clinical rational use of monitoring method in FK506 blood drug concentra tion.Methods The separation was performed on a Ultimate xB-C18 column with a mobile phase of water (containing 2 mmol/L ammonium acetate and 0.1 ml/dl formic acid) and methanol (containing 0.1 ml/dl formic acid).The way of eluting was gradient.Mass spectrum detection method was ESI positive ion mode and the MRM transitions of FK506 m/z 821.5～ 768.5 and Ascomycin m/z 809.4～756.4.Selected part of the whole blood samples of FK506 in bone marrow transplant patient and respectively were tested by HPLC/MS/MS method,CMIA method and Elecsys method.Then,three methods for the detection of FK506 density were compared.Results The standard curve of FK506 was linear over the range of 0.5～50 ng/ml,Y=0.228X-0.003 08 (r=0.999 0).FK506 blood concentrations were not significantly different in HPLC/MS/MS method,CMIA method and Elecsys method.Conclusion The HPLC-MS/MS method in the detection of FK506 was established and can be used for monitoring of whole blood concentration of FK506 in bone marrow transplant patients.
