Objective To assess the distribution of vaginal microflora in healthy women and investigate their cognition of lower reproductive tract infection-related knowledge as well as personal hygiene habits and character of behavior in seeking medical treatment. Methods Total of 1660 healthy women who had physical check-ups at the Medical Center of Renji Hospital were selected and received gynecologic examination, as well as routine examination, pH examination and bacterial culture of the vaginal discharge. In addition, 860 of them were randomly selected for questionnaire survey, in which reproductive tract infection -related knowledge and personal hygiene habits as well as behavior in seeking medical treatment were involved. Results Among the 1660 eensused women, vaginal average pH was 4. 16±0.21. The positive rate of Candida in vaginal discharge routine examination was 3.86% (64/1660), which was lower than that in aerobes culture 7.71% (128/1660). Candida alhicans was the most populous species 78.9% (101/128) ,followed by 7.8% (10/128) and 7.0% (9/128) for the Candida glabrata and Candida krusei respectively. The most populous species of vaginal microflora were hemolytic streptococcus A (63.80%, 1059/1660), Staphylococcus epidermidis (14.28%, 237/1660), and Enterococcus faecalis (D) group ( 11.44%, 190/1660). The questionnaire survey showed that 88.4% (760/860) of 860 women took active treatment when feeling unwell, 92.1% (792/860) of them had good hygiene practices, and only 21.2% (182/860) had the habit of vaginal douching. In addition, 50.0% (430/860) of them had the desire to obtain reproductive health knowledge through out-patient consultation. Conclusions Vulvovaginal Candida disease ranks the first in all types of vaginitis, among which, Candida albicans is the most populous species followed by the Candida glabrata and Candida krusei. Hemolytic streptococcus A and Staphylococcus epidermidis are the most common species of vaginal mieroflora in healthy women. The censused women have high awareness of reproductive health care and pay mueh attention to common gynecologic diseases such as lower reproductive tract infection. Nevertheless, we should strengthen the public education of reproductive health-related knowledge.

Objective To investigate the mechanisms modulating the functions of dendritic cells (DCs) and suppressing the activation and proliferation of T cells by transforming growth factor-β (TGF-β).Methods Mouse splenic DCs were purified with CD11c+ immunomagnetic beads and the purity of isolated DCs were detected by flow cytometry.Gene chip was used to detect gene expression in DCs after stimulation with TGF-β, and then real-time PCR was performed to analyze the differentially expressed genes in microarray at mRNA level.The activation and proliferation of CD4+ T cells which were co-cultured with DCs after stimulation with TGF-β were detected by flow cytometry.Results The purity of DCs reached over 95% after isolation.TGF-β down-regulated the expression of cell surface markers CD53, CD69, CD33, CD74 and CD93 on DCs;decreased the expression of chemokines Ccl3, Ccl5, Ccl9, Ccl6, Ccl17, Cxcl10, Ccl22, Ccl4, Ccr7, Ccl2, Cxcl9 and Ccl7;inhibited the expression of inflammatory cytokines IL-2ra, IL-12rb2, IL-15ra, IL-1b and IL-15.Moreover, the DCs-mediated activation and proliferation of CD4+ T cells were suppressed by TGF-β.Conclusion TGF-β inhibits the DCs-mediated activation and proliferation of CD4+ T cells by suppressing the expression of surface markers on DCs and down-regulating the expression of chemokines and inflammatory cytokines.

Objective To explore the clinical effect of corticosteroids combined with Chinese medicine sequential therapy of Guishao Dihuang pill and Yupingfeng granules on children nephrotic syndrome (NS) with yin deficiency of liver and kidney.Methods Fifty patients (the loss of children during the course of treatment were not included in the statistical analysis) with definitely diagnosed NS accompanied by yin deficiency of the liver and kidney admitted to the First Affiliated Hospital of Gannan Medical University from January 2012 to June 2016 were enrolled,and they were divided into control group and observation group by random number table,25 cases in each group.Conventional treatment of western medicine and long-term treatment of corticosteroids were given to the two groups.In addition,sequential therapy of Guishao Dihuang pills and Yupingfeng granules was given to the observation group on the bases of conventional treatment.The changes of platelet aggregation rate (PAT),cholesterol,cortisol,T cell subsets CD3,CD4,CD4/CD8 were observed before and after treatment for 8 weeks and 6 months,then the clinical efficacy and infection,etc.complications were compared between the two groups.Results There were no statistical significant differences in cholesterol,cortisol and curative effect compared between the two groups before treatment and after treatment for 8 weeks and 6 months (all P ＞ 0.05).Mter treatment for 8 weeks and 6 months,the PAT,cholesterol,cortisol of two groups were significantly decreased compared with those before treatment,while CD3,CD4 were obviously higher than those before treatment,and the degrees of changes of PAT,CD3,CD4 in the observation group were more remarkable than those of the control group [PAT:treatment after 8 weeks was (63.01 ± 6.99)％ vs.(66.62 ± 4.65)％,treatment after 6 months was (51.42 ± 7.74)％ vs.(57.01 ± 6.77)％,CD3:treatment after 8 weeks was 0.56 ± 0.06 vs.0.52± 0.06,treatment after 6 months was 0.61 ± 0.05 vs.0.58 ± 0.03,CD4:treatment after 8 weeks was 0.33 ± 0.06 vs.0.30 ± 0.05,treatment after 6 months was 0.39 ± 0.05 vs.0.33 ± 0.06,all P ＜ 0.05].CD4/CD8 ratio was significantly higher in observation group after treatment for 8 weeks and 6 months than those before therapy (1.68 ± 0.76,1.82 ± 0.95 vs.1.16 ± 0.67,both P ＜ 0.05);the number of patients with infection in observation group was obviously lower than that of the control group (86 cases vs.175 cases,P ＜ 0.05).Conclusions The therapeutic effect of corticosteroids combined with Chinese medicine sequential therapy of Guishao Dihuang pills and Yupingfeng granules for treatment of children NS with yin deficiency of the liver and kidney is better than that of using western medicine therapy alone,as the combined sequential therapy has good effects on reduction of infection,anti-thrombosis and elevation of immunity.

BACKGROUND:Artificial knee joint replacement is the main surgical method for the treatment of severe knee joint deformation, but due to the limited existing knee prosthesis type. The stature of Fujian population in southeast China was shorter than that of the north. The size of artificial knee joint usual y did not fit for patients in clinic. The substitution effect was poor.
OBJECTIVE:To measure the geometric parameters of proximal surface and cross-section of adult female tibia in southeastern area of Fujian Province of China, and provide basic data for design and replacement of artificial knee joint in females.
METHODS:We chose 85 cases of dry female skeleton in southeastern area of Fujian Province of China, measured tibial plateau width, medial tibial plateau width and anteroposterior diameter, lateral tibial plateau width and anteroposterior diameter. We col ected clinical normal proximal tibial CT data of 36 patients (38-65 years old), with scan range of 30 cm (intercondylar eminence 30 cm) and layer thickness of 0.625 mm. Mimics 16.0 three-dimensional reconstruction software was used to measure above indexes and cut the reconstructed models with thickness of 3 mm, total y 10 layers. We divided its widest distance into four equal parts, and measured tibial anteroposterior diameter on three points. Statistical software was used to analyze the linear relationship between the data.
RESULTS AND CONCLUSION:The experiment has successful y obtained geometric parameters of tibial specimens of adult females in southeastern area of Fujian province of China. Tibia platform inside and outside diameters were greater than the width inside and outside;inside and outside diameter and inside and outside width were similar. Ten segment planes of tibia, inside and outside diameters were always less than middle anteroposterior diameter. Three groups of data increased firstly, and then reduced. There were positive correlations between tibia length and width of the medial tibia platform, the lateral tibia platform width and anteroposterior diameter, the medial tibia platform width and anteroposterior diameter, and the lateral tibia platform width and anteroposterior diameter (P<0.05). These results suggested that relevant parameters of tibial plateau adult women in southeastern area of Fujian province of China showed some regular changes. Our results may provide quantitative reference data for the design and operation of artificial tibial plateau.

Objective To analyze the expression of synaptophysin (SY) in hippocampal dentate gyrus of rats with hypoxic-ischemic brain damage(HIBD) after the injection of bone marrow stromal cells(BMSCs) and its supernatant into the lateral ventricle and to explore the mechanism of potential effects. Methods Eighty 7-day-old sprague-dawley(SD) rats were randomly divided into sham group, control group, cell group and supernatant group, with 20 rats in each group. The HIBD model was established via the ligation of left carotid arteries followed by 2-hour hypoxia. One week later, control group was injected with 0.01 mol/L PBS via the left ventricle. Meanwhile, cell and supernatant group were injected with BMSCs and supernatant harvested from BMSC culture, respectively, via the same route. For spam group, the left carotid arteries were separated but not ligated, and no hypoxia treatment was imposed on this group. They also received 0.01mol/L PBS injection one week post surgery. After 8 weeks, the expression of SY in the dentate gyrus of rats was measured. Results Compared with sham group, model group showed significantly lower IOD (integral optical density) of SY positive material in the dentate gyrus(P < 0.05). Compared with model group, supernatant group and cell group exhibited significantly increased IOD values (P < 0.05), but there was no significant difference between cell group and supernatant group (P > 0.05). Conclusions BMSCs and supernatant injected via the lateral cerebral ventricle can increase SY expression in the hippocampal dentate gyrus of HIBD rats and promote synapse formation. The mechanism of this effect may be related to cytokine secretion by BMSCs which promotes synapse formation.

Objective To investigate the potential pathogenesis of Focal cortical dysplasia (FCD), we performed cDNA microarray analysis to obtain gene expression profile of FCD. Methods Three FCD samples and three normal controls were enrolled. Total RNA of the brain tissues were extracted. The difference gene expressions between FCD group and control group was detected using Affymetrix gene chip. The up and down-regulated genes were confirmed by Real-time PCR. Further, the related signal pathways involved in the pathogenic mechanisms of FCD were predicted by bioinformatics. Result In FCD, two up-regulated genes C21orF2 and AU152162 and 5 down-regulated genes ENPP2, ANLN, IP6K3, UGT8, and AZGP were found. Compared the FCD samples with the normal controls , there were significantly different in all down-regulated genes (P < 0.05), while the up-regulated genes were not (P > 0.05). Using bioinformatics analysis, the ENPP2 , UGT8 , and AZGP1 protein which located in the cell membrane or secreted into the extracellular matrix may be involved in the formation of the myelin sheath and the development of the nervous system by the lipid metabolism and LPA signaling pathway. Conclusion ENPP2, UGT8 and AZGP1 may be involved in pathogenesis of FCD through the process of myelin sheath formation and LPA signal pathway , which warrants further study to know their roles in the pathogenesis of FCD.
