Objective To determine whether exposure to electromagnetic radiation results in behavioral effects of rat pups.Methods Wistar rats,either male or female,were divided randomly into four groups respectively:control(CTR),100 seconds(S1),1000 seconds(S10)and 3000 seconds(S30),then each of them were exposed to electromagnetic radiation of 100 kV/m field amplitude of corresponding time.For the day of exposure till 2 months later.they were mated with the rats in the same group and their offspring were divided into four groups(F-GTB,F-S1,F-S10,F-S30)correspondingly.Behavioral changes occur in 2-month old and 6-month old rat pups were found between radiation groups and control,and in Y-maze test,beth male and female pups in F-S10 significantly learned fewer times than their control(total study times:male 14.6±3.9 vs 21.1±7.8,female13.4±3.0 vs 25.8±8.8;false times:male 3.5±2.4 vs 7.8±5.4,female 3.4±2.6 vs 11.0±7.2).In open field test,both maze,male pups in F-S1 and F-S30 learned more times than control in total study time(24.2±8.9 vs 14.1±5.2.30.7±12.4 vs 14.1±5.2).In step throush test and open field test,no significant differences were found between radiation groups and control.Conclusion There was significant genetic effect exposed to electromagnetic radiation of 100 kV/m,mainly manifested in rat pups in growth period but without long-term effect.

Objective To investigate the chnicopathogenical significance of c-jun N-terminal kinase(JNK) and multidrug resistance associated protein 1 (MRP1) expression in colorectal cancer. Methods The expression of JNK and MRP1 was detected in a tissue microarray containing 72 spots of colorectal cancer tissue and 40 spots of nor-mal colorectal tissue by immunohistochemisty. Results The positive expression rate of JNK and MRP1 expression was 47.22% and 51.39% respectively in colorectal cancer,significantly higher than that in normal colon tissue. JNK protein expression was not closely related to gender, age, tumor size and location (P>0.05), but closely related to tumor differentiation,lymph node metastasis,distsnt metastasis and Dukes staging (P<0.05). MRP1 protein expres-sion was not closely related to gender,age,tumor size,location and tumor differentiation(P> 0.05), but closely relat-ed to lymph node metastasis, distant metastasis, Dukes staging (P<0.05). Conclusions The JNK expression in cancer is corrlated with maligant biological behavior and may be involved in the chemotherapeutic resistance by upreg-ulating the expression of MRP1.

Objective In order to analyze the pollution level of PM10 and PM2.5, as well as their sources in large and moderate scale shopping centres. Methods Using the portable aerosol monitor detected the PM10 and PM2.5 on different locale floors in Zhongyuan Supermarket, Commerce Building and Foodstuff Centre in Pingdingshan City area. Results The average mass concentration of PM10 in Zhongyuan Supermarket,Commerce Building and Foodstuff Centre were 0.212 mg/m3, 0.108 mg/m3, 0.056 mg/m3 and that of PM2.5 were 0.179 mg/m3, 0.092 mg/m3, 0.043 mg/m3 respectively. The pollution level of PM10 of all the shopping center didn't exceed the related standard. The average mass concentration of PM2.5 in Zhongyuan Supermarket,Commerce Building all exceeded the standard ,and the times of exceeding standard were 1.75 and 0.42. The people volume of flow was more masses, and the concentration of PM10 and PM2.5 were more higher. The mass concentration of PM10 and PM2.5 in every sites of the same floor was significantly different (P

AIM: To observe the expression of TGF ?1 in hepatocytes during acute hemorrhagic and necrotic pancreatitis (AHNP) and to study the relationship between TGF ?1 and apoptosis in hepatocytes. METHODS: AHNP was induced in 40 rats weighting 260-280 g by intraductal administration of 5% sodium taurocholate. The pathologic morphologic changes of liver and pancreas were observed under light microscope. The hepatocyte apoptosis was examined through TdT (terminal deoxynucleotidyl transferase) mediated dUTP nick end labeling (TUNEL) and the expression of TGF ?1 in hepatocytes was analyzed through immunohistochemistry. RESULTS: The liver injuries were found at 3 h after the inducement. These changes were aggravated with the development of the disease. The apoptotic hepatocytes were found after 3 h (P

Objective To investigate the clinical significance of NaviCam magnetic-controlled capsule endoscopy (NMCE) system in the examination of upper gastrointestinal tract.Methods A total of 39 healthy volunteers were enrolled in the present study.NMCE system was used to examine upper gastrointestinal tract.The safety,gastric preparation,visualization and comfort of the subjects were evaluated.Results Visualization of the Z-line,gastric cardia,fundus,body,angulus,antrum and pylorus was subjectively assessed as more than 75％ mucosa in 19 (48.71％),37 (94.87％),25 (64.10％),30 (76.92％),39 (100.00％),39 (100.00％),and 39 (100.00％),respectively.The observation time was 1.5,3.0,8.0,17.0,3.0,3.0,5.0 min respectively.The capsule was driven into duodenum positively in 25 (64.10％).Seven subjects went into small bowel without control.The one-time visualization efficacy was 97.43％ (38/39).Only one subject felt foreign body sensation.All subjects extracted the capsule within 7 days.Conclusion Our study provides a preliminary assessment of the NMCE on its feasibility and safety.It is comfortable with no chance of cross-infection.NMCE system is a useful tool for upper GI examination and will have a good future.

Purpose To evaluate features of the left ventricular twist in patients with atrial septal defect (ASD) using speckle tracking imaging (STI) in order to guide clinical application.Materials and Methods Fifty-eight patients with ASD confirmed by ardiac ultrasound in Shanghai Children's Medical Center from October 2015 to January 2016 were enrolled in this study as case group,which were further divided into group ASD-A with 30 cases and group ASD-B with 28 cases according to the volume of right ventricular.The volume of right ventricular was significantly increased in the group ASD-A,but the volume of right ventricular was not significantly increased in the group ASD-B.At the same time,30 normal children with matched age and sex were chosen as control group.The parameters of left ventricular twist motion in each group were measured and compared by using STI.Results In group ASD-A,The basal and apical part of 6 children rotated counterclockwise.Compared with those in the control group,the basal rotation angle and apical rotation angle of left ventricular in group ASD-A were significantly higher (P＜0.01),and the peak twist and torison of left ventricular in group ASD-A were also higher (P＜0.05).Compared with those in the control group,only the apical rotation angle in group ASD-B was higher (P＜0.05),but the rest parameters of the left ventricular twist motion in group ASD-B were not statistically significantly higher (P＞0.05).Conclusion The significant increase in the volume of right heart load in ASD impacts on the basal and apical rotation of left ventricular.
