Objective To investigate how to optimize the protocol of embryo cryopreservation to improve the success of frozen-thawed embryo transfer (FET), reduce multiple pregnancy rate and increase the cumulative pregnancy rate from one oocyte retrieval process. Methods The clinical data of 1 166 FET cycles were retrospectively analyzed and separated into different groups:445 for vitrification and 721 for slow-freezing. The vitrification group was divided into single embryo (28 cy?cles), double embryos (71 cycles) and triple embryos (346 cycles). 0-1 optimal embryo was called O0-1 group (235 cycles), 2 optimal embryos were called O2 group (80 cycles), 3 optimal embryos were called O3 group (130 cycles). The difference preg?nancy outcomes (implantation rate, clinical pregnancy, abortion rate and live-birth rate) were compared between groups. Results (1) There were significantly higher embryo survival rate(98.3%vs 73.1%), embryo recovery rate without damaging (83.3%vs 62.1%), implantation rate(36.8%vs 29.9%), clinical pregnancy(57.1%vs 44.0%) and live-birth rate(47.9%vs 34.5%) in vitrification group than those of slow freezing group(P<0.05). (2) There were significantly higher clinical pregnan?cy rate(62.7%vs 39.4%vs 32.1%), multiple pregnancy rate(37.6%vs 10.7%vs 0%)and live-birth rate(52.6%vs 31.0%vs 21.4%)in triple embryos group than those of the single and double embryos groups (P<0.05). (3) There were significantly higher implantation rate(33.0%vs 27.1%), clinical pregnancy(65.2%vs 48.1%), multiple pregnancy rate(38.0%vs 20.4%) and live-birth rate(56.2%vs 39.2%) in O2-3 group than those of O0-1 group(P<0.05). (4) There were significantly higher im?plantation rate(36.8%vs 26.3%) and multiple pregnancy rate (46.7%vs 21.3%) in O3 group than those of O2 group (P<0.05). There were no significant differences in clinical pregnancy(69.2%vs 58.8%), abortion rate(15.6%vs 10.6%), ectopic preg?nancy rate(0 vs 0), live-birth rate(58.5%vs 52.5%) and preterm birth rate(26.3%vs 14.3%) between two groups (P>0.05). Conclusion Vitrification technology can improve the clinical pregnancy and live-birth rate, and decrease multiple preg?nancy rate. Two optimal embryos in one tube are supposed to be the preferred method for embryo cryopreservation.

Objective To investigate the sexual activity of pregnant women in the third trimester and its influencing factors. Methods A retrospective investigation was conducted among 338 postpartum women in our hospital who delivered between June and August in 2003. The questionnaires was completed by every subjects supervised by special trained persons on the 2nd to 4th day postpartum. Results More than a quarter (96/338, 28.4%) of the pregnant women had coitus during the third trimester. The increase of sexual activity was positively related to their partners who were less educated (Wald ?~2=9.68,P

Objective To know the lavatory improvement in the rural areas in Shandong Province in 2005 and to present the data for the decision of the lavatory improvement in countryside in the future. Methods In 2005, 164 villages in 45 counties were chosen and questionaire was used to conduct the investigation. Results 15 338 different type lavatories were constructed, of which the indoor toilets occupied 71.70%, the outdoor toilets occupied 28.30%. About 11.19 million yuan RMB was spent on the program, the average cost of each lavatory was 729.60 yuan RMB. Conclusion The program of lavatory improvement in the rural areas has been finished in Shandong Province in 2005, the data are satisfactory.

Objective To investigate the correlation between food intolerance and Henoch-Sch(o)nlein purpura (HSP) in children and the efficacy of food forbidden or alternative therapy. Methods The levels of IgG against several common food in serum obtained from 40 children with HSP were measured by ELISA. The efficacy of food forbidden or alternative food therapy was assessed after 3 months. Results Total positive rate of serum food-intolerant IgG antibodies in HSP children was 92.5%. Among these 14 intolerant foods, the positive percentage of egg was the highest (33.8%), followed by tomato (14.9%), milk (13.5%) and morrhua (12.2%). Significant differences of the sort and degree of food intolerance existed among different age groups (t=2.257, P=0.045), but not between boys and girls (t=1.053, P=0.315), city and countryside (t= 1.388, P=0.193). There was no linear correlation between total food intolerance and serum IgG level (t=0.793, P=0.445). Food intolerance had no direct relation to immune complex deposition in kidneys of HSP nephritis (r =-0.262, P =0.387). The efficacy of adjusting diet was 95% . Conclusions HSP is closely related to food intolerance. Egg is the most common intolerant food. Food forbidden or alternative therapy shows acceptable efficacy in the treatment of most Henoch-Sch(o)nlein purpura children.
