Objective To evaluate the effects of pregnancy weight control program based on structure- process- outcome model to improve women′s health status and pregnancy outcomes. Methods On the basis of Donabedian′s structure- process- outcome quality of care model, a pregnancy weight control program designed and carried out for the middle and late pregnancy. The structure, process and outcome of the pregnancy weight control program were evaluated to ensure the quality of the pregnancy weight control program. In addition, the women′s pregnancy outcomes were investigated after intervention. Results the prenatal BMI in the intervention group [ (23.06±1.11) kg/m2 ] were lower than those in the control group [(25.52±1.89) kg/m2 ], and the incidence of cesarean section (including cesarean section without indication), neonatal macrosomia, labor block, neonatal asphyxia, postpartum hemorrhage, pregnancy induced diabetes and hypertension in the intervention group were significantly lower than those in the control group, P<0.01 or 0.05. Conclusion Donabedian′s structure- process- outcome quality of care program is an effective approach to improve women′s pregnancy outcomes.

Objective To investigate the effect of social support and childbirth self-efficacy-enhancing intervention on primiparas' childbirth self-efficacy,coping ability and pain during labor.Methods A randomized controlled trial was used with double blindness design.One hundredand six primiparas were recruited as the intervention group and control group,53 cases in each group.The two groups adopted the routine prenatal care.In addition,the intervention group participated in twice childbirth self-efficacy-enhancing educational courses.The Chinese Childbirth Self-Efficacy Inventory (CBSEI) was used to conduct the comparison between before and after intervention;the interventional effects in the natural childbirth pregnant women were compared between the two groups by adopting the Visual Analogue Scale (VAS) and Childbirth Coping Behavior Scale (CCB);the Multidimensional Scale of Perceived Social Support (MSPSS) was adopted to analyze correlation between the social support level with the CBSEI and CCB.Results The intervention group finally had 52 cases of effective sample and the control group had 51 cases of effective sample.The CBSEI score after intervention in the intervention group was 282.04± 27.38,which was higher than 236.69± 45.39 before intervention.The CCB score in the intervention group was 56.78 ± 6.95,which was significantly higher than 48.03 ± 6.26 in thecontrol group,and the VAS score in the intervention group was 6.96 ± 1.39,which was lower than 8.35 ± 1.43 in the control group,the difference was statistically significant(P＜0.01).The MSPSS score in the two groups was positively correlated with the OE score,efficacy expectancy (EE) score and CBSEI score before intervention(r=0.269,0.289,0.317,P＜0.01).Conclusion Launching the childbirth self-efficacy-enhancing educational intervention of the social support system can effectively improve the childbirth self-efficacy and coping ability of primiparas,and reduce the intrapartum pain level.

Object To investigate the in vivo antioxidant effect of the extract from Rosmarinus officinalis L. and its active substances. Methods The contents of MDA, the activites of SOD and GSH Px in serum, heart, liver, brain and skeleton muscle were determined in oxidative stress mouse model caused by exercise. Results It was found that in serum, liver, heart and skeleton muscle except the brain, the contents of MDA were decreased and the activities of SOD and GSH Px were increased by 250 mg/kg and 500 mg/kg of total phenolic diterpenes (TPD) extract taken. Conclusion The results showed that R. officinalis has prominent antioxidant effect in exercise mice and the active constituents may be phenolic diterpenes.
