Objective To investigate the relationship between different expression of gastrocolic omentum visfatin (VF) mRNA and gestational diabetes mellitus (GDM) in late trimester pregnancy. Methods One hundred cases of pregnant women in late trimester were divided into two groups, including 45 GDM women( GDM group) and 55 normal glucose tolerance women( NGT group). Semi-quantitative RT-PCR was applied to determine the expression of VF mRNA in gastrocolie omentum. Fast-blood glucose, insulin,cholesterol(TC) and triglyceride (TG) levels were measured. The progestational body mass index(BMI) and the homeostasis model assessment(HOMA) insulin resistance(IR) were calculated in these cases. Results The expression of gastrocolic omentum VF mRNA in GDM group and NGT group were 0.8 ±0.4,0.5±0.3. Fast-blood glucose levels were(4.12±0.14),(3.65±0.13) mmol/L. Insulin levels were (72±5) ,(61±5) pmo]/L TG levels were (5.6±0.3), (3.8±0.3) mmol/L TC levels were(5.6±0.9 ), (3.9±0.3) mmol/L HOMA-IR were 12.5±5.9,9.5±0.8. The progestatianal BMIs were(22.6±0.8), (20.9±0.4) kg/m2. All the indices in the GDM group were significantly higher than NGT group (P<0.05). Furthermore, the expression of gastrocolic omentum VF mRNA had a positive correlation with BMI (r=0.32, P<0.01), but had no association with insulin resistance or metabolic parameters. Conclusion The experiment demonstrates that different expression of VF mRNA has a strong correlation with GDM and obesity.

Phthalic acid esters (PAEs) are commonly used plasticizers and solvents. Human body is exposed and absorbed mainly through diet, skin and air inhalation. The biological samples such as urine, blood, saliva, semen and breast milk generally contain PAEs and their metabolites, but the concentrations of PAEs metabolites vary in different samples. In the general population, the levels of PAEs are higher in children than in adults, and higher in women than in men; the levels of PAEs are higher in the occupational population than in the general population. In this paper, the research of PAEs related human biomonitoring in the general population and occupational population at home and abroad is reviewed, so as to provide the basis for reducing the exposure of PAEs and related health risk.

Objective :
To understand the status of rural environmental sanitation and summer diarrhea among rural residents in Zhejiang Province,and to provide evidence for improvement of rural environmental sanitation and prevention and control of summer diarrhea.
Methods :
The stratified random sampling method was used. Five or six counties each were selected from the east,middle and west of Zhejiang Province;five townships(excluded Chengguan Town)were selected from each selected county;four villages were selected as field survey points from each township;five households were selected from each survey point;one family member(householder or housewife)was selected from each selected household. The information about the environmental sanitation status and prevalence of summer diarrhea were obtained by literature review,interviews,questionnaire suvey,field investigation and laboratory tests. Logistic regression model was used to analyze the influencing factors for occurrence of summer diarrhea among rural residents.
Results :
There were 2 000 households surveyed. In the past two weeks,108 households had families with diarrhea and the prevalence of diarrhea was 5.40%. A total of 1 828 households disposed the household waste in the garbage bins or pools,accounting for 91.40%. There were 1 926 households with organized sewage discharge,accounting for 96.30%. There were 768 households with nymphs found in the kitchen,accounting for 38.40%;404 households with live egg sheaths found,accounting for 20.20%;592 households with cockroach traces found,accounting for 29.60%;564 households with rat traces found,accounting for 28.20%;and 1 206 households with flies found,accounted for 60.30%. There were 1 314 households with disease vectors around the house,accounting for 65.70%. There were 1 944 household with sanitary toilets,accounting for 97.20%. A total of 1 915 households had habits of drinking boiled water,accounting for 96.57%. The results of multivariate logistic regression analysis showed that rat traces found in the kitchen(OR=2.026,95%CI: 1.362-3.013)were a risk factor for summer diarrhea in rural residents,while drinking boiled water(OR=0.272,95%CI: 0.091-0.811)was a protective factor.
Conclusion
The sanitary environment and family health habits of rural residents were related to the prevalence of diarrhea in summer. Paying attention to kitchen hygiene and drinking boiled water could prevent summer diarrhea.

Objective To determine whether unilateral-only interictal discharges on pre-surgical scalp EEG or multimodal pre-surgical evaluation are associated with surgical outcomes in patients with MR imaging-negative temporal lobe epilepsy (TLE) who underwent standard anterior temporal lobectomy (ATL). Methods One hundred and seventeen patients with TLE who underwent standard ATL from January 2000 to December 2013 were enrolled. According to the seizures at interictal period, these patients were divided into unilateral-only interictal discharge group (n=54) and bilateral interictal discharge group (n=63). According to the preoperative assessment, these patients were divided into multimodal evaluation group (n=72, two and above evaluation strategies besides electroencephalogram) and single modal evaluation group (n=45, electroencephalogram+one evaluation strategy). Follow-up for 12 months was performed; postsurgical outcomes included excellent outcome, defined as Engel class I, and non-excellent outcome, defined as Engel II-IV. Kaplan-Meier survival analysis and Cox proportion hazards were performed to compare the prognoses of patients from different groups. Results Totally, 73 patients (62.4%) achieved excellent outcome following ATL. In 54 with unilateral-only interictal discharges, 41 had excellent outcome; and in 63 with bilateral interictal discharge group, 32 patients had excellent outcome; significant difference in percentage of excellent outcome was noted between the two groups (P<0.05). Fifty of 72 patients receiving multimodal pre-surgical evaluation achieved excellent outcome, and 25 of 45 receiving single modal evaluation achieved excellent outcome; significant difference in percentage of excellent outcome was noted between the two groups (P<0.05). However, the patients with unilateral-only interictal discharges receiving multimodal pre-surgical assessment did not achieve further excellent outcomes as compared with those receiving single modal evaluation, without significant difference (P>0.05). Conclusion Multimodal pre-surgical evaluation is associated with better outcomes following standard ATL in the patients with MR imaging-negative TLE; however, for patients with unilateral-only interictal discharges, multimodal pre-surgical evaluation method may be not essential as compared with single modal pre-surgical evaluation method.
