We investigated the Toxop lasma infection prevalence among planned pregnant women in Chongqing ,and to pro‐vide reference for the first level intervention of birth defects in the region .A total of 11 953 planned pregnant women were se‐lected by proportionally stratified multi‐stage random sampling method .Questionnaire survey was given to the women ,and blood samples were collected .Specific IgM and IgG antibodies against Toxoplasma were detected with ELISA .Results showed that among the 11 953 cases surveyed ,Toxoplasma IgM was positive in 71 cases ,with the positive rate of 0 .59% ;IgG was positive in 771 cases ,with the positive rate of 6 .54% .The positive rate of IgM and IgG antibodies in the metropolitan core re‐gion of the city was higher than that in the suburb areas (χ2 =35 .28 ,P<0 .000 1 ;χ2 =82 .65 ,P<0 .000 1) .The positive rate of IgM antibody increased with the educational level (χ2trend=3 .25 ,P=0 .001 1) .The positive rates of IgM and IgG varied in occupations among women (χ2 =13 .93 , P= 0 .016 0;χ2 = 15 .58 ,χ2 =0 .008 1) ,with the highest rate of public officials . Planned pregnant women with the history of abnormal pregnancy outcomes had higher positive rate of T .gondii IgM and IgG antibodies than those in the control (χ2 =6 .85 ,P=0 .008 9;χ2 =59 .25 ,P<0 .000 1) .There was no significant difference of IgM positive rate between the planned pregnancy women who had closed contact to cats and the control group (χ2 =0 .23 ,P=0 .628 6) ,while the positive rate of IgG was higher than that of the control group (χ2 =9 .95 ,P=0 .001 6) .T .gondii infec‐tion rate was on the low level of planned pregnant women in Chongqing .Adverse pregnancy outcomes are related to Toxoplas‐ma infection .

Objective To investigate the cognition and attitude towards the elderly family nursing among nurses and college students in Chengde, and analyze its influencing factors. Methods A total of 1000 college students and nurses in Chengde were investigated by self-designed questionnaire about their cognition and attitude to elderly family nursing. Results Nurses' cognition and attitude towards the elderly family nursing was better than nursing college students, medical students were better than non-medical students; and there was no statistical significance about their expectation for government's senior citizen service among different groups. Conclusions More attention should be paid to family members' attitudetowards the elderly home care, and should strengthen the elderly family care through various way.

Objective To explore the mechanisln of action of Jianpiyishen Decotion on renal fibrosis and provide experimental evidence for chnieal application.Methods The Wistar male rats were randomly divided into four groups.They were normal control group(N group),model group(M group),low dose treatment group(L group)and high dose treatment group(H group).AⅡanimal models were made of CRF with subtotal renal ablation except the N group.Interference began at one week after operation.After being interfered for 8 weeks,blood serunl and nephridial tissues were taken out.Serum urea nitrogen(BUN)and creatinine(Scr)and fibronectin(FN)were detected.Results In N group。There were light expression in renal tubniointerstitial substance,cellula epithelialis basal meulbnule and Vascular smooth muscle.In M group,FN was strong expressed in renal tubulointerstitial substance and renal tubde,and also in glomerular mesangium.There was significant difference between N and M group(P

Objective To investigate the protective effect of human umbilical cord mesenchymal stem cells (huc-MSC) on the ischemia-reperfusion injury (IRI) of moderately fatty liver in rats. Methods The rat fatty liver model was established by fat-rich diet feeding. 60 female SD rats were randomly divided into MSC-treated and control groups (n = 30). MSC-treated group was infused with MSC (2 x 106 cells resuspended in 1.5 ml of sterile phosphate-buffered saline solution, PBS) by intra-venous injection through the tail vein. The first dose was administered on day 1 before IRI, followed by another dose on day 3 postIRI. The control group was injected with sterile PBS alone at the same intervals. Blood and liver samples were collected at day 1,4 and 7 (10 rats at each time point) post-IRI respectively to test enzyme activities,biochemical and histological changes. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), superoxide dismutase (SOD), malondialdehyde (MDA) and tumor necrosis factor α (TNF-α) in liver tissue were measured. The pathological changes of liver tissue and apoptosis of hepatocytes were also assessed. Results Compared to the control group, the levels of ALT, AST, TNF-α, and MDA declined in the MSC-treated group on day 1 and day 4 post-IRI ( P ＜ 0. 05 ), while no difference was observed on day 7 post-IRI ( P ＞ 0. 05). There was no difference of the level of SOD between the two groups on day 1,4 and 7 post-IRI (P ＞0. 05). Pathological examination revealed inflammatory injury in the MSC-treated group was alleviated compared with that in the control group. Conclusion huc-MSC effects protection on the IRI of fatty liver in rats.

The incidences of overweight and obesity in planned pregnant women in Chongqing were 24.15 ％ and 5.02％.Those living in southeast Chongqing,being old age,with primary school education,and unemployment are the key crowds and deserve health management in regard of overweight and obesity as well as reproduction.

Objective To explore factors affecting long-term compliance to weight management (WM) of patients with congestive heart failure (CHF)and to provide evidence for improving patients' compliance.Methods In-depth semi-structured interviews based on reinforcement theory were conducted among 18 CHF patients who received WM intervention over 6 months.The data were analyzed by Colaizzi analysis program.Results Three themes were found:precipitating factors such as the correct perception of disease and self-efficacy,the factors of positive reinforcement such as early gains from WM,readmission,follow-up,family and social support,as well as the factors of negative reinforcement such as gaining nothing during long period,physical and mental disorders.These above factors made long-term compliance to WM of 50％ of the participants dynamic and fluctuant.Conclusions Medical staff should identify patients'compliance at different stages in time during follow-up,analyze the factors that affect their compliance,and then grasp the optimal timing of intervention to perform targeted,multiform and multiple health education to improve compliance.

Objective To screen thyroid function among planned pregnant women in Chongqing, to guide prenatal and postnatal care. Methods Proportional multi-stage stratified cluster random sampling method was adopted to enroll 11 953 planned pregnant women for questionnaire, physical examination, and serum samples collection. Results The median TSH was 2. 04 mIU/ L, P25 = 1. 36 mIU/ L,P75 = 2. 99 mIU/ L. TSH levels being normal, higher, and lower than the reference were 91. 47% , 6. 20% , and 2. 33% , respectively. In Northeast Chongqing, the proportions of median TSH level and TSH level above the upper limit were higher than those in other regions(P<0. 05). With improved education, proportions of TSH above the upper limit and below the lower limit declined(P<0. 05). With the increase in body mass index, the proportion of those whose TSH was above the upper limit showed elevated trend(P<0. 05). In women with history of adverse pregnancy outcomes, their median TSH was higher than that in the control group, and those, whose TSH level exceeded the upper limit, yield higher results than those in the control group(P<0. 05). In women with higher fasting blood glucose The median TSH level was lower than that in normal blood glucose group( P<0. 05), with the fasting plasma glucose concentration and TSH negatively correlated(P<0. 05). Conclusion The abnormal rate of TSH level in planned pregnant women was 8. 53% in Chongqing. The abnormal rate varies by different regions, education levels, body mass indexes, and blood glucose levels. Previous history of adverse pregnancy outcomes was related to elevated TSH levels. It is necessary to take pre-pregnancy thyroid function screening investigation.
