Objective To analyze the relationship between pre - pregnancy body mass index ( BMI) ,gestational weight gain ( GWG) and the birth weight of infants,and explore the effect of weight change before and during pregnancy on low birth weight ( LBW) and macrosomia. Methods Women were enrolled by the Chinese Pregnant Women Cohort Study during first trimester. Each respondent's weight before and during pregnancy and the birth weight of infant were collected after fellow up. Prepregnancy BMI was divided into underweight,normal and overweight /obesity groups and GWG was divided into suitable, insufficient and excessive groups. Multivariate Logistic regression was adopted to explore the relationship be- tween pre-pregnancy BMI,GWG and newborn's birth weight. Results Women's prepregnancy BMI and GWG were associated with neonatal birth weight ( all P<0. 05) . Prepregnancy overweight or obesity ( OR=2. 339,95% CI: 1. 674-2. 282,P<0. 001) and excessive GWG ( OR= 1. 398,95% CI: 1. 188-1. 978,P= 0. 048) were shown as risk factors for macrosomia. Insufficient GWG increased LBW risk ( OR = 1. 479, 95% CI: 1. 461-1. 679,P= 0. 035) while excessive GWG declined LBW risk ( OR= 0. 428,95% CI: 0. 225 -0. 817,P= 0. 010) . Under weight-insufficient GWG was risk factor of LBW ( OR= 1. 335,95% CI: 1. 048 -2. 319,P= 0. 048) while normal BMI-excessive GWG ( OR= 1. 088,95% CI: 1. 016-1. 675,P= 0. 038) and overweight /obesity-excessive GWG ( OR= 1. 498,95% CI: 1. 244-2. 017,P= 0. 046) were associated with higher risk of delivering macrosomia. Conclusions Prepregnancy BMI and GWG were associated with infant's birth weight and women were suggested to maintain their weight in recommended range before and during pregnancy.

Schistosomiasis is a neglected tropical disease which is socioeconomically devastating and a significant cause of morbidity in endemic countries or regions. Some countries and regions have brought down the prevalence of schistosomiasis through positive prevention and control programs. However in the past few years with the social and economic development and globalization re?emergence and spread of schistosomiasis led to a growing concern that new endemic areas may occur. This article analyzes the epidemiological situation and the strategies to control schistosomiasis in China and African countries.

Objective To investigate the risks and benefits of interventions promoting placental transfusion (PT) at delivery [delayed cord clamping (DCC) or umbilical cord milking (UCM)] compared with early cord clamping (ECC) on outcomes among very low birth weight infants (VLBWI).Methods A systematic search was conducted of PubMed, EMBASE, ClinicalTrials.gov, China Academic Journal Network Publishing Database and Wanfang Medical Databases (January 1965 to July 2014) for randomized controlled trial (RCT) articles relating to PT strategies (DCC and UCM) in VLBWI.The Cochrane Handbook 5.1.0 was used to evaluate the methodological quality and RevMan 5.3 software from Cochrane Collaboration was used for metaanalysis.The fixed effect or random effect model was adopted according to the result of heterogeneity, Results We identified 14 eligible studies describing a total of 659 neonates with an average birth weight < 1 500 g.There were eight studies for DCC and six studies for UCM.Compared with the control, benefits of greater PT decreased any grade intraventricular hemorrhage (IVH) (nine studies, OR=0.49, 95%CI: 0.32-0.77, P < 0.01), increased the blood pressure at four hours of life (eight studies, MD=4.42, 95%CI: 3.85-4.98, P < 0.01), and also showed higher initial hemoglobin (Hb) level (six studies, MD=3.52, 95%CI: 1.67-5.37, P < 0.01) and lower incidence of sepsis during the hospital stay (five studies, OR=0.46, 95%CI: 0.26-0.83, P=0.01).No differences were observed between the groups about the fllowing indicators (all P > 0.05): 5-minute Apgar scores (MD=0.01,95%CI:-0.21-0.22), admission temperature (MD=0.13, 95%CI:-0.15 to 0.41), peak serum bilirubin levels (MD=0.59, 95%CI:-0.13 to 1.31), initial reported hematocrit (MD=3.48, 95%CI:-0.46 to 7.43), mortality before discharge (OR=0.63, 95%CI:0.31-1.25), Bell's stage 2 or greater necrotizing enterocolitis (OR=0.62 ,95%CI: 0.29-1.33), rates of transfusion due to anemia (OR=0.63, 95%CI: 0.35-1.15) and oxygen therapy at 36 weeks of corrected age (OR=0.79, 95%CI: 0.46-1.34).Conclusions It is suggested that enhanced PT (both DCC and UCM) at birth is safe and provide better neonatal outcomes than ECC for those VLBWI, most notably reduces the overall IVH occurrence and lower the incidence of sepsis.The optimal umbilical cord clamping practice and UCM among VLBWI infants remains uncertain and long-term neurodevelopmental outcomes are warranted.
