Objective To analyze the clinical outcomes of patients treated with in vitro fertilization and embryo transfer (IVF-ET) and influence factors of pregnancy rate. Methods We retrospectively analyzed the clinical data of 12 491 cycles, including 6832 fresh IVF/intracytoplast single sperm injection (ICSI) cycles and 5659 frozen embryo transfer (FET) cycles from 2005 to 2007. Results The clinical pregnancy rate per cycle was 32. 99% (2254/6832)in fresh embryo transfer program, and the live birth rate was 25.75% (1394/5413); the early pregnant loss rate was 9. 36% (211/2254), and the prenatal defect rate was 1.45% (25/1722). Through analysis of these patients' basic data, we found that the patients' age, causes for infertility, egg retrieval and cycle number affected the pregnancy rate. Using logistic regression method, we found that patients′ age was the most important factor affecting pregnancy outcome. In FET cycles, the clinical pregnancy rate was 38.08% (2155/5659), significantly higher than fresh embryo transfer cycles. Conclusions IVF-ET treatment is a safe and effective method for infertility couples. However, the female age and poor ovarian response are the main factors affecting pregnancy rate. Thawed embryo transfer can increase the accumulated pregnancy rate effectively.

OBJECTIVETo study the pollution status of Legionella species in hot spring vacation center and the related factors.
METHODSField surveys were performed in four big hot spring vacation centers of Changping district. Uniform questionnaires was used and colony count was made together with the isolation of Legionella species from hot spring water based on mip gene typing.
RESULTS47 isolates of Legionella pneumophila (Lp) from 87 samples showed 4 serotypes as Lp1, Lp6, Lp12, Lp5 with percent of 57.45%, 21.28%, 14.89%, 6.38% respectively. The hot spring centers controlled the temperature of recycled water between 34-47 degrees C by hot water heating and filtrating system. All the isolates were cultured from the hot water with temperature between 34-44 degrees C: 56.75% (21/37) in high temperature (40-47 degrees C) and 61.90% (26/42) in low temperature (34-39.9 degrees C). There were no statistically significant difference between the high and the low temperature samples (P > 0.05). In the four hot spring vacation centers, the pH value was under control at 6.4-7.3 and the ambient temperature was under control between 26-28 degrees C. The humidity was controlled between 56% -69% relative humidity, which were the best growing conditions for the Legionella species. Disinfectors as chlorine deviratives was used in the four hot spring vacation centers. Though the concentration of chlorine in the water was 0.3-0.5 mg/L, 14.29%-48.00% of the samples were still positive of having Legionella species.
CONCLUSIONThe pollution of Legionella species was considered to be quite serious in the four hot spring vacation centers and the predominant serotype was Lp1. The pH and temperature of the hot spring water, ambient temperature and humidity and the way of heating up the water were the best conditions for the growth of Legionella species in these centers. Because of the high temperature of the hot spring water, chlorine of the disinfector volatilized quickly, affecting the effect of disinfection. The result revealed that water temperature achieving 44 degrees C could have had the effect of prevention.

OBJECTIVETo study the principle and surgical managements for the patients with anatomic variants of hepatic artery in the procedure of pancreaticoduodenectomy (PD).
METHODSOne hundred and seventy-six patients who underwent PD between January 2000 and July 2007 were investigated retrospectively. Hepatic arterial variants were analyzed according to the intraoperative finding and CT imaging were reviewed postoperatively.
RESULTSHepatic arterial variants were found intraoperatively in 20 cases of all 176 patients. Accessory right heptic artery, replaced right heptic artery and common heptic artery arising from the superior mesenteric artery (SMA) were present in 9 (5.1%), 5 (2.8%), 4 (2.3%) cases respectively,and replaced right heptic artery coming from the gastroduodenal artery was present in 2 cases (2.9%). All the variants of hepatic arteries arising from the superior mesenteric artery could be observed in spiral CT imaging. Most of the variant arteries were dissected intact intraoperatively except 2 cases with accessory right heptic artery arising from SMA.
CONCLUSIONSPerforming CT scan preoperatively, especially CTA,is effective to diagnose these disorders. Skillful surgical techniques can manage the anatomic variants safely.

OBJECTIVETo assess the role of probiotics in the prevention of neonatal necrotizing enterocolitis (NEC) and to investigate the risk factors for NEC.
METHODSA total of 2528 hospitalized neonates between January 2002 and May 2005 were assigned into either receiving prophylactic use of probiotics bifoco (Prevention group, n=1182) or without probiotics supplementation (Control group, n = 1346). The incidence of NEC was compared between the two groups. The risk factors for NEC were investigated by conditional logistic regression multifactorial analysis.
RESULTSThere were 19 cases of NEC in the Control group (1.41%), but only 6 cases in the Prevention group (0.51%) (P < 0.05). Gestational age (OR = 5.521), hypoxicdouble ended arrowischemic encephalopathy (OR = 3.887), specticemia (OR = 4.854) and critical illness scores (OR = 5.989) were the risk factors for NEC, while the prophylactic use of probiotics was an independent protective factor for NEC (OR = 0.255).
CONCLUSIONSThe prophylactic use of probiotics may reduce the incidence of NEC in neonates.
