Objective To explore the pertinent communication strategy of health education for parasitic diseases.Methods A cross-sectional study was carried out.Before the health education intervention,the knowledge,attitude and practice(KAP)for parasitic diseases of 199 and 250 farmers in two provinces of Sichuan and Yunnan in southwest China were investigated with questionnaire by using the method of PPS.Results Most of the farmers used the simple and crude toilets and their health status were poor,and there were only 7.57% of people having the bio-gas facilities.The awareness rate of the knowledge on malnutrition caused by parasitic diseases was 34.30% and the awareness rate of knowledge about anemia caused by parasitic diseases was 29.62%.There were 81.74% of farmers who believed helminthic drug and 74.61% of people who tended to buy drug by themselves.The health knowledge of the residents mainly came from the interpersonal communication and TV,and the farmers preferred TV,poster and brochure to get the health knowledge.Conclusion The health education with posters,TV and intervention communication is one of the important measures to control parasitic diseases.

Objective To investigate the effect of mesenchymal stem cells transplatation on angiogenesis and secretion of cytokines after rat myocardial infarction. Methods Harvested rat mesenchymal stem cells were cultured and labeled in vitro. And at the same time, myocardial infarct model was set up by liquid nitrogen cryoinjuring the left ventricular free wall. 4 weeks later, 2?10 6 mesenchymal stem cells or cold D-Hanks liquid were injected into several different points of infarcted area. At 1, 2 and 4 weeks after mesenchymal stem cells transplatation, specimens were acquired from infarcted area. Then cell morphology and capillary density were measured, and vascular endothelial growth factor(VEGF) and transforming growth factor ?(TGF-?) expression levels were assayed by RT-PCR. Results Mesenchymal stem cells were alive at 1, 2 and 4 weeks after transplantation and had a trend toward differentiation and maturation in vivo. The number of capillary vessels in per infarcted area (0 1 mm 2) in experiment group increased compared with control group. And the number of capillary vessels in experimental group had a trend to decrease in experiment group(P

Objective To investigate the effect of mesenchymal stem cells transplantation on heart function and the expression of Ca 2+ -ATPase (ERCA) mRNA after rat myocardial infarction. Methods Wistar inbred rat mesenchymal stem cells were cultivated, proliferated and labeled in vitro. Myocardial infarct models were set up by liquid nitrogen cryoinjuring the free wall of left ventricle. 4 weeks later, 2?10 6 mesenchymal stem cells or cold D-Hanks solution were injected into several different points of infarcted myocardial area of experiment group and control group rats. In addition, 5 Wistar inbred rats served as normal group only got thoracotomy twice. 4 weeks after transplantation, all rats received cardiac function test and specimens from infarcted area were got for the expression assay of SERCA2 mRNA by RT-PCR. Results Mesenchymal stem cells were alive at 1, 2 and 4 weeks after transplantation and had a trend toward differentiation and maturation in vivo. Traumatic dynamic measurement was applied to assay heart function by Buxco system, which showed that SLVP and +dp/dt were the highest in normal group, next in experiment group, and the lowest in control group, which LVEDP was the lowest in normal group, next in experiment group, and the highest in control group. The expression level of SERCA2 mRNA in control group was much lower than that in normal group(0.988?0.004 VS 1.824?0.009,P

To improve the precision of image registration based on corner detection, a relative position function between multiple points to determine matching points accurately. First the corners in images are detected using Harris detector, and clustering method is used to eliminate most wrong matches after coarse screening. Then the proposed relative position function is used as a criterion of precise matching. Finally the image registration process is accomplished by affine transformation. Results show that the proposed algorithm is more effective and accurate than conventional registration algorithm.

Objective To summarize the clinical result of patients undergoing endoscopic vein harvest (EVH) technology to collect greater saphenous vein (GSV) in coronary artery bypass graft (CABG) operation, and to assess the operation outcome of EVH. Methods A total of 862 patients underwent primary CABG, among whom saphenous vein of 482 patients were taken using EVH, and the others by open vein harvesting (OVH) based on patients' willingness. The operation risk factors and complication were compared between the two groups. The 64 multi-slice computed tomography (64-MSCTA) was used to evaluate the vein grafts patency after surgery for 1 year. The vein patency between the two groups was compared. Results There was no significant difference in risk factors of incision complication between two groups ( P>0.05). But the incidence of various incision complication was significantly lower in EVH group (10.2%,49/482) compared with that in OVH group (35.0%,133/380) ( P<0.05). The time of harvesting and the length of conduits was similar between two groups (P>0.05). After 1 year's follow-up, the vein graft patency were 86.0%(404/470) and 87.1%(324/372) in EVH group and OVH group, and there was no significant difference ( P>0.05). Conclusions The decrease in incision complication of EVH is unquestionably superior to those of OVH, especially for those patients with risk factors of incision complication. The EVH vein graft has good patency in short time.

Objective: This study explores the miR-150 expression and its clinical significance in mantle cell lymphoma (MCL). Methods: The miR-150 and c-Myc expression was measured in 29 primary MCL tissue samples and 7 normal donors through quantita-tive real-time polymerase chain reaction. MiR-150 expression was detected in Mino and HBL-2 cells after c-Myc was knocked down by small interfering RNAs. MiR-150 was analyzed in tet-treated P493-6 cells with Myc turned off. The number of tumor colonies in the BL-2 cells transfected with pre-miR-150 was determined through colony formation assay, and c-Myb was detected through Western blot. Results: Compared with the normal donors, miR-150 expression was significantly downregulated and c-Myc was considerably overexpressed in MCL. Moreover, MCLs with high Myc expression had a significantly low miR-29 expression. MiR-150 was upregu-lated in the Mino and HBL-2 cells with c-Myc knockdown. MiR-150 was evidently upregulated in P493-6 cells after c-Myc was turned off. MiR-150 overexpression suppressed colony formation and c-Myb expression of HBL-2. Conclusion: MiR-150 is downregulated in MCL, which may be related to c-Myc overexpression. The recovery of miR-150 suppresses MCL cell survival. These results indicate that miR-150 may be a potential therapeutic target of MCL.
