RESUMO
Objective To study the vaginal microecology of the patients in the outpatient department of Obstetrics and gynecology in China.Methods A multicenter cross-sectional study was conducted in gynecologic clinic of 9 collaborative hospitals in China.200 consecutive patients were collected in each hospital and their vaginal microecology combined with related factors were analyzed.Results A total of 2 093 specimens were collected in this study.The detection rate of Trichomonas was 5.5%(115/2 093). The detection rate of Candida mycelia was 15.9%(333/2 093), with germinal spores was 4.1%(86/2093).The detection rate of bacterial vaginosis was 18.8%(394/2 093).The distribution results of vaginal flora in patients showed that the normal flora accounted for only 27.3%(571/2 093).The normal flora with the insufficiency of H2O2 accounted for 23%(480/2 093).The bacteria inhibiting flora accounted for 3.8%(79/2 093).The abnormal microflora(non BV type)accounted for 14.9%(312/2 093).The abnormal microflora(BV intermediate type)accounted for 13.4%(280/2 093).The abnormal microflora(BV type)accounted for 17.6%(369/2 093).The average pH of vaginal discharge was 4.58 ±0.495.There was no significant difference of the incidence of trichomonas and bacterial vaginosis between north and south of the Yangtze river, while the detection rate of fungal hyphae and the fungal spores is significantly higher in the south than that in the north.The analysis results of factors affecting the microecology showed that age and contraception methods were two important factors.The patients′age from bacteria inhibition group was 49.64 +16.68 which was significantly higher than that of the other microecology groups.The proportion of abnormal microflora of patients from the oral contraceptive group was 40%(20/50).The proportion of abnormal microflora of patients from IUD group was 36.6%(63/172).Compared with these two contraception methods, the proportion of abnormal microflora of patients from condoms usage group was 27.8%(91/327)which was significantly lower.The incidence of abnormal leucorrhea in the normal group was 37.7%, which was significantly lower than that of other abnormal groups.Conclusion This study showed the vaginal microecology status of the Chinese outpatient ′s clinic and found that the vagina microecology was related to age, region and contraceptive methods.The typical manifestation of microecological abnormality is the increase of leucorrhea.(Chin J Lab Med,2018, 41:287-291)
RESUMO
@#Objective To establish a coupled model combining the rat brain nuclei microelectrode recordings and the behavioristics for rehabilitation experiment. Methods The modified indwelling tube connection fixed device was put inside the rats' back, and the microprobes were implanted into related neural nucleus. A signal connection was made between self-administration system and electrophysiological data acquisition system. The rat was addicted after training by self-administration system. The related cerebral nucleus electrophysiological sig-nals were recorded in different states of addiction. Results and Conclusion The modified indwelling tube connection fixed device has a bet-ter quality for reducing the phenomenon of leak. The signal was well in the combination of two different systems. The signals for the rat's ac-tion and neural electrical were recorded in the same time.

RESUMO
ObjectiveTo explore the clinical application of preoperative biliary drainage in the treatment of patients with malignant obstructive jaundice (MOJ) with acute cholangitis (AC). MethodsA retrospective study was performed on the clinical data of 74 patients with MOJ and AC who were treated with preoperative biliary drainage in our hospital from January 2010 to December 2014. In those patients, 29 patients treated with percutaneous transhepatic biliary drainage (PTCD) were assigned to PTCD group, and 35 patients treated with endoscopic retrograde biliary drainage (ERBD) were assigned to ERBD group. The levels of total bilirubin (TBil), direct bilirubin (DBil), and alanine aminotransferase (ALT) before and after treatment, total hospitalization cost, average duration of hospitalization, and postoperative complications were compared between the two groups. The advantages and disadvantages were compared between the two preoperative biliary drainage approaches. Between-group comparison of continuous data was made by t test, and between-group comparison of categorical data was made by χ2 test. ResultsIn both groups, the levels of TBil, DBil, and ALT were significantly reduced after treatment (all P＜0.05). The ERBD group had significantly larger decreases in the levels of the three biochemical indices than the PTCD group (all P＜0.05). The ERBD group had significantly shorter average duration of hospitalization and significantly lower total hospitalization cost than the PTCD group (t=3.172, P＜0.05; t=2.562, P＜0.05). The incidence of acute pancreatitis in the ERBD group was significantly higher than that in the PTCD group (14.28% vs 3.45%, P＜0.05); however, the incidence rates of biliary tract bleeding, biliary tract infection, and resection or puncture site infection were significantly lower in the ERBD group than in the PTCD group (all P＜0.05). ConclusionPreoperative biliary drainage can substantially control AC symptoms and improve liver function. Compared with PTCD, ERBD achieves shorter duration of hospitalization, lower total hospitalization cost, and lower incidence rates of complications after treatment, which can be taken as the first choice for the treatment of MOJ with AC.

RESUMO
Objective To investigate the effects of splenectomy on peripheral immune cells including Th17 cells in patients with portal hy-pertension and to analyze the influence of splenectomy on their immune function.Methods Twenty-five portal hypertension patients trea-ted with splenectomy in No.180 Hospital of PLA from June 2012 to June 2014 were selected as observation group,and 25 healthy controls who underwent physical examination in the same period as control group.Flow cytometry was used to determine the percentages of CD3 , CD4,and CD8 T lymphocytes,CD4/CD8 ratio,and percentage of Th17 cells in the peripheral blood of portal hypertension patients (1 day before operation and at 7 days,1 month,and 3 months after operation)and healthy controls.ELISA was used to evaluate the changes in ser-um interleukin-6 (IL-6),interleukin-17 (IL-17),and interleukin-23 (IL-23).Comparison between groups was made by one-way ANOVA and LSD-t test.Results Before splenectomy,the portal hypertension patients had significantly lower percentages of CD3, CD4,and CD8 T lymphocytes and CD4/CD8 ratio (P0.05 for all).At 7 days,1 month,and 3 months after operation,the percentage of Th17 cells and levels of their associated inflammatory cytokines (IL-6,IL-17,and IL-23)in portal hypertension patients decreased gradually (P<0.05 for all).Conclusion Th17 cells and their associated inflammatory cytokines (IL-6,IL-17,and IL-23)are reduced in portal hy-pertension patients treated with splenectomy,so their immune function can be improved.
