Objective To investigate the clinical effect of mifepristone in treatment of perimenopausal dysfunctional uterine bleeding.Methods 80 cases of patients with perimenopausal dysfunctional uterine bleeding were selected and randomly divided into control group and research group,with 40 cases in each group.The control group was in the diagnosis of curettage after 10 days of oral provera 10mg every night before going to bed,stopped drug application in 14 days,15 days to retreat hemorrhages oral provera 10mg/day,stayed for 10 days,repeated drug use 5 months.The research group was treated with oral mifepristone every night before going to bed since cleaning up the uterus,12.5mg,for 6 months.Outpatient follow -up for 6 months,the recent curative effect,long -term curative effect,hormone level changes,anemia and adverse drug reactions were observed.Results The total effective rate of the research group was 95.0%,which of the control group was 82.5%,there was statistically significant difference(χ2 =7.82, P =0.005);The recurrence rate of the research group was 5.0%,which of the control group was 15.0%,there was statistically significant difference(χ2 =5.56,P =0.018).The FSH,LH,E2 and P of the two groups were decreased, but which of the research group were lower significantly than those of control group,the differences were statistically significant (all P <0.05).The decreased degree of endometrium in the research group was larger than that of the control group,the difference was statistically significant(P =0.0001).Conclusion Treatment of mifepristone perimenopausal dysfunctional uterine bleeding is significant,safe and convenient,which is worthy of clinical application.

This study was aimed to investigate the curative effect on external application and rectal instillation with Chinese medicine in the treatment of chronic renal failure (CRF) with acute gouty arthritis (GA). A total of 82 CRF patients with acute GA from the First People's Hospital of Hengyang City were randomly divided into the study group (n = 42), which was treated with external application and rectal instillation with Chinese medicine, and the control group (n = 40), which was treated with prednisone. The comparison was made on symptoms and body signs of GA, blood uric acid, creatinine, creatinine clearance, adverse reaction, and recurrence rate between two groups. The re-sults showed that there was no significant difference on alleviating of joint swelling and pain between the study group and the control group. Compared with pretreatment, the blood uric acid and creatinine were significantly decreased after treatment in the study group (P< 0.01). The creatinine clearance was obviously increased (P < 0.05). There were no significant differences on blood uric acid, creatinine and creatinine clearance in the control group before and after treatment. There was no adverse reaction in the study group. In the one-month follow-up, there were only three recurrent cases in the study group, which were obviously better than the control group (P< 0.01). It was concluded that external application and rectal instillation with Chinese medicine had a good curative effect on CRF with acute GA in the near future with low recurrence rate and no adverse reaction, which was worthy of popularizing in the clinical practice.

The epidemiological trends of leprosy showed the increase of mean age at onset and type ratio, and the decrease of incidence in children. Conclusion The epidemicity of leprosy has been continuously dropping in Zhejiang Province due to the sustained effort and effective control.

Objective To determine the human milk insulin(HMI) concentrations of healthy,gestational diabetes mellitus (GDM) and gestational impaired glucose tolerance (GIGT) lactating mothers and their correlative factors and to explore the effect of HMI on growth and development of neonates. Methods HMI of colostrum and mature milk collected from 148 healthy lactating mothers and 46 GDM/GIGT mothers were determined by radioimmnuoassay. The intergroup HMI levels were compared by Wilcoxon test. Results (1) In the GDM/GIGT group, colostrum HMI was 28.81 μU/ml(13. 84-43.14 μU/ml), significantly lower than that of mature milk which was 57.50 μU/ml(36. 70-82. 73 μU/ml) (Z=-4. 828,P=0. 000). HMI of mature milk in the healthy group was 35.88 μU/ml(25.91-46.85 μU/ml), lower than in the GDM/GIGT group (Z=-2.874,P=0.004). ( 2 ) The colostrum HMI of the mothers underwent cesarean section was 23.64 μU/ml (14.90-38.51 μU/ml) lower than in the vaginal delivery ones which was 38.89 μU/ml(23.14-65.54 μU/ml)(Z= -4. 510, P= 0. 000). (3) HMI of mature milk in mixed feeding cases was 42.58 μU/ml (26.60-73.06 μU/ml),significantly higher than that of breast feeding ones which was 36.32 μU/ml(26.00-46.16 μU/ml)(Z=-2. 377,P=0.019). (4) Both HMI in colostrum and mature milk were positively correlated with maternal BMI (P＜0.05). Conclusions The mode of delivery significantly affects the HMI in colostrum. GDM/GIGT and the feeding patterns have some effects on HMI levels in mature breast milk. The HMI level is positively correlated with maternal BMI.

Objective To determine whether glucagon-like peptide-1 (GLP-1) receptor PET/CT with 68Ga-exendin-4 is accurate in localizing insulinomas, by comparing with conventional imaging techniques.Methods In this prospective cohort study, patients with biochemically proven endogenous hyperinsulinemic hypoglycemia from March 2014 to November 2016 were recruited consecutively.68Ga-exendin-4 PET/CT, CT, MRI, endoscopic ultrasound (EUS), and SSTR imaging were performed before elective surgery.Surgical pathology results were considered as the gold standard.Sensitivity based on patient-analysis and positive predictive value (PPV) based on lesion-analysis were calculated and compared using χ2 test and generalized score test.Results A total of 109 patients were recruited (47 males, 62 females;average age (45.1±14.8) years), and 96 of them with insulinomas proved pathologically were included in the main assessment.Thirteen patients with positive 68Ga-exendin-4 PET/CT findings did not undergo surgical intervention.Based on patient-analysis, the sensitivities of 68Ga-exendin-4 PET/CT, CT, MRI, EUS and SSTR imaging for detecting insulinomas were 98.96%(95/96), 81.25%(78/96), 79.41%(54/68), 81.40%(35/43) and 21.84%(19/87), respectively.Based on lesion-analysis, the PPV of the above 5 methods were 100%(102/102), 97.56%(80/82), 95.16%(59/62), 83.72%(36/43) and 90.48%(19/21), respectively.68Ga-exendin-4 PET/CT showed the highest diagnostic sensitivity than others (all P<0.01) and higher PPV than MRI, EUS and SSTR imaging (all P<0.05).Conclusion 68Ga-exendin-4 PET/CT is a highly sensitive imaging technique for detection of insulinoma.

Objective To develop a formulation of generic Valsartan Tablets and evaluate the quality consistency in vitro.Methods Diovan(R)~ HCT (80 mg) was used as the reference drug.In order to determine the best formulation and the best preparation processing,the single factor experiments were applied to determining the best formulation and the best preparation processing.And dissolution test was used as the evaluation index in the single factor experiments.Meanwhile the dissolubility of generic Valsartan Tablets and original preparation was investigated in four different media to evaluate the similarity of dissolution by calculating similar factor (f2).Results The dissolution was above 85％ of three batches of generic Valsartan Tablets in the phosphate buffer (pH 6.8).The similar factors were all more than 50 in the water,hydrochloric acid solution (pH 1.2),and acetate buffer solution (pH 4.5).Conclusion The f2 similarity factor results indicate a similarity in the reference drug and generic Valsartan Tablets which were developed by single factor experiments,which means the quality of genetic Valsartan Tablets is qualified.

Objective To investigate the resistance of Staphylococcus to erythromycin and clindamycin and detect the percentage and gene for inducible resistance. Methods Disk diffusion method was used to test the resistance phenotype of Staphylococcus aureus and coagulase-negative staphylococcus according to the standards of NCCLS. The inducible resistance of erythromycin to clindamycin was checked by D-test and the gene for erythromycin ribosome methylase was detected by polymerase chain reaction.Results Co-resistance to erythromycin and clindamycin accounted for 62.7% and 54.8% in MRSA and MRCNS respectively. D-test positive rate was 17.7% among all Staphylococcus tested. The rate of inducible resistance to clindamycin (D-test positive) was 67.6% and 45.3% in Staphylococcus aureus and coagulase-negative Staphylococcus which possessed erythromycin resistant and clindamycin sensitive by individual disk diffusion test. The predominant gene for inducible resistance was ermC with the percentage of 74.5%.Conclusion The inducible resistance of erythromycin to clindamycin in Staphylococcus should be checked by D-test in clinical microbiology laboratory in order to help physicians to select MLSB antimicrobial agents correctly.
