Objective To investigate the effects of treatment of syphilis in pregnancy on perinatal prognosis. Methods Patients of syphilis in pregnancy from Hainan Provincial People′s Hospital and Haikou Municipal Maternal and Child Health Center during 1995.1 to 2001.1 were collected for retrospective analysis. Pregnant women with syphilis were divided into treated group and untreated group according to whether they received penicillin anti syphilis treatment or not during pregnancy. Results The total number of deliveries in the 2 hospitals during that period was 18 701, and 61 out of 9 805 women screened for syphilis were positive, giving an incidence of 6 2/1000. The perinatal mortality rates were 11 2% in treated group and 83 3% in untreated group, and incidences of congenital syphilis were 17 6% and 72 7% respectively. Conclusion Syphilis in pregnancy is a serious complication to harm the fetus. Screening of syphilis during pregnancy is necessary, and penicillin treatment is effective which may reduce the perinatal mortality rate and the birth of congenital syphilis baby.

ObjectiveTo observe the protective effect of tetrahydroxystilbene glucoside (TSG) on rats' hippocampal neuronal damage induced by glutamate (Glu) in the culture.MethodsHippocampus was isolated from newborn SD rats and dispersedly cultured in the medium for 9 days. Neurons were incubated with TSG (5—100μmol/L) for 24h, the cells were washed twice with Lock's solution without Mg2+,then Glu 500 μmol/L was added. Thirty min later, the reaction was terminated by washing the monolayer cells twice with the Lock's solution and then cultures were kept at 37℃ for 24h. Cell viability was measured by MTT method and cell membrane damage was determined by LDH leakage; with Fluo-3/AM as an intracellular calcium indicator and added into the bathing medium, fluorescent intensity of intracellular free calcium were observed through laser scanning confocal microscopy (LSCM).ResultsAfter the treatment with 5—100μmol/L TSG for 24h, the decrease of cell viability and the increase of LDH leakage caused by Glu was obviously resisted dose dependently. TSG inhibited increase of Ca2+ in cytoplasm, compared with model group.ConclusionTSG can significantly promote the cell viability and reduce the cell membrane damage in Glu treating hippocampal neurons. The neuroprotective activities of TGS is mediated by inhibiting Ca2+ overload in cytoplasm.

Objective:China was categorized as one of the 68 countdown countries to achieve the United Nations Millennium Development Goals (MDG) 5. This paper aimed to analyze the situation of maternal survival, and coverage of proven cost effective interventions in China, where specific attention was paid to disparities. Methods: National maternal and child mortality surveillance data were used to estimate maternal mortality ratio (MMR). Coverage for proven interventions was analyzed based on National Health Services Survey, where experts' consultations were made for complementation. Results: There had been a significant reduction of MMR in China, however great disparities existed, with rural Ⅱ to Ⅳ areas experiencing 2 to 5 times higher maternal mortality risks than urban areas and accounting for over 70% maternal mortality burdens. Postpartum hemorrhage, pregnancy associated hypertension, embolism and sepsis were the leading causes, and over 75% of the maternal mortality was caused by preventable or curable causes. Maternal health services utilization decreased in accordance with region' s development level. Socioeconomic factors like financial difficulties were the main obstacles hindering access of care.Even those who made deliveries in hospitals faced different probabilities in receiving qualified care according to their socioeconomic standings. Conclusion: China is on track to achieve MDG 5, however great disparities exist. It is necessary to specifically target rural types Ⅱ to Ⅳ areas. Major causes of maternal mortality which can be prevented or averted through the provision of essential obstetrical care. Yet as compared with maternity health needs, insufficient coverage of maternal and child health (MCH) care services and poor service quality are the leading predisposing factors contributing to maternal mortality in China.

BACKGROUND: Adipocytes are derived from preadipocytes, which are induced by mesenchymal stem cell differentiation. This study explored the mechanism of mesenchymal stem cell differentiation into adipocytes and provided a new thinking for preventing and treating obesity.OBJECTIVE: To investigate the isolation and culture of BMSCs from rabbits in vitro, and the method of differentiating into adipocytes.DESIGN: An observational controlled in vitro experiment.SETTING: Department of Histology and Embryology, Binzhou Medical College, and Yunnan Pharmacological Laboratories of Natural Products.MATERIALS: Totally 12 healthy Japanese rabbits aged 6-8 weeks of 200 to 300g of either sex were provided by Experimental Animal Center of Kunming Medical College. Dexamethasone, 3-isobutyl-1-methylxanthine and insulin (Sigma, USA) and indomethacin (ALEXIS, USA) were used in this study.METHODS: Experiments were performed at the Yunnan Pharmacological Laboratories of Natural Products between July 2004 and January 2005. BMSCs were harvested from the femurs, tibias and humerus bones of the rabbits, and then purified and proliferated. After primary culture, the subcultured cells were cultured in media including 1μmol/L dexamethasone, 0.5mmol/L 3-isobutyl-1-methylxanthine, 10mg/L insulin and 0.2mmol/L indomethacin. The disposal was accorded with the animal ethical standards.MAIN OUTCOME MEASURES: Growth curve of the third passage of cells was evaluated by modified MTT method. Salmon pink lipid drop appeared after Oil Red O staining under a light microscope.RESULTS: After 72 hours of adipocyte induction, lipid droplet appeared in BMSCs. With the prolongation of induction time, lipid vacuoles were found and cells changed from fusiform to round or polygon. At week 3, approximately 80% BMSCs were induced into adipocytes as detected by Oil Red O.CONCLUSION: Rabbit BMSCs isolated and cultured in vitro can be induced into adipocytes in the media containing 1μmol/L dexamethasone, 0.5mmol/L 3-isobutyl-1-methylxanthine, 10mg/L insulin and 0.2mmol/L indomethacin.

Objective To present the status of smoking control in the Health and Family Planning System in Hubei Province, and to provide scientific basis for smoking control through secret investigations. Methods During the period from July to August in 2015, 168 sanitary Health and Family Planning institutions were chosen by stratified selection to make questionnaires based on Evaluation Standards for Smoke-free Health and Family Planning Institutions issued by the National Health and Family Planning Commission of the People's Republic of China. Secret investigations were conducted in 165 sampled institutions and comparisons were made between smoke-free environment establishment as well as execution processes according to the fraction after converting into centesimal system (actual score/reserved portion × 100). Results The overall score for smoking control in Health and Family Planning System of Hubei Province has climbed to 79.29 ± 12.40.compared to that of 2011 has increased, but 1.6 lower than the national comprehensive evaluated score of 2014. The score of the city (82.14 ± 10.51) proved to be higher than that of the province (66.51±19.69) and the county, (75.35±13.40);disease control institutions (84.77± 9.45) enjoyed a higher score that the others with lowest scores in medical institutions (72.80 ± 14.95);Xianning won the highest score (88.52±5.12);Jingmen (69.81±5.16) and Xiaogan (67.92±7.98) proved to be the lowest in their scores. Nine regions in 17 embraced a lowest discrepancy of over 30 scores and the highest discrepancy of 50.94 scores between the highest score and the lowest among different institutions;12.73% (21/165) medical institutions had no publicity materials; 5/17 municipal institutions and 3/10 county level institutions were still found selling cigarettes, with only 46.06%(76/165) institutions reaching the standard of banning smoking in indoor places, 21.21%(35/165) institutions still have indoor smoking in non-working places, 1.82%(3/165) institutions have indoor smoking in working places. Only 18 (32.14%) institutions out of 56 medical institutions investigated have established smoking cessation clinics. Conclusions Banning-smoking work is less optimistic in general for Health and Family Planning System in Hubei Province, especially for substratum health and family planning institutions. All kinds of departments should take drastic measures to guaranttee the establishment of smoking-free environment.
