Objective To evaluate the teaching effects of micro-lecture based on the wechat platform in new nurses'training in operating rooms.Methods Fifteen new nurses in the operating room in July 2014 were selected as observation group,and thirteen new nurses in July 2013 were selected as control group.The multimedia-aided teaching mode was applied in the two groups,while micro-lecture based on the we-chat platform was implemented in the observation group.The theory and operating skills between two groups were evaluated by examination, and a random inquiry about satisfaction with new nurses was directed on surgeon and seniors nurses.Resulsts 100% of the nurses in obser-vation group accepted and preferred wechat in continuing education.The new nurses’performance in theory and skill test in the observation group was significantly higher than that of the control group (t =2.901,P =0.011;t =2.225,P =0.029).In addition,the surgeon’s and seniors nurses’satisfaction with new nurses in the observation group was significantly higher than that of the control group (Z =6.425,P =0.011).Conclusion Micro-lecture based on the wechat platform can motivate nurses’learning enthusiasm and positivity,and effectively improve their theoretical knowledge and professional skills.

Objective To explore the effects of dipeptidyl peptidase ( DPP-4 ) inhibitor on proteins expression of Bcl-2 and Bax of islet β-cells through increasing the expression of islet γ amino acid butyric acid ( GABA) . Methods A total of 50 rats of clean grade were studied. Among them, ten rats were randomly selected as normal controls, the remaining forty rats were fed with high-fat diet and then intraperitoneal injection with streptozotocin, the diabetic rats models were then established. Rats were randomly divided into three groups:i. e. diabetic control group, DPP-4 inhibitor group, and antagonist group ( DPP-4 inhibitor and GABA receptor antagonist). Six weeks later, blood glucose, serum insulin, glucagon, and the proteins expression of GABA, Bcl-2, and Bax of islet β-cells were measured. Results ( 1 ) Compared with diabetic control group, serum insulin was increased(P<0.05),bloodglucoseandserumglucagonweredecreasedinDPP-4inhibitorgroup(P<0.05). (2) Compared with DPP-4 inhibitor group, serum insulin was decreased(P<0. 05), blood glucose and serum glucagon were increased(P<0. 05) in antagonist group. (3) Compared with diabetic control group, the expression of GABA was increased(P<0. 05), the expression of Bcl-2 protein was increased (P<0. 05) in pancreatic β-cells in DPP-4 inhibitor group. ( 4 ) Compared with diabetic control group, the expression of GABA in pancreatic β-cells was increased in antagonist group(P<0. 05) . Compared with DPP-4 inhibitor group, the expression of Bax protein in pancreaticβ-cells was increased in antagonist group(P<0. 05) , while the expression of Bcl-2 protein was decreased (P<0. 05). Conclusions DPP-4 inhibitor could increase the secretion of insulin, decrease the secretion of glucagon, up-regulate expression of anti-apoptosis protein Bcl-2, and down-regulate expression of apoptosis protein Bax in pancreatic β-cells through increasing the expression of GABA, inhibiting pancreatic β-cells apoptosis and protecting the damagedβ-cells in type 2 diabetic rats.

Objective To study the accuracy of real-time continuous monitoring system (RT-CGMS) at different stages and its association with glucose excursion. Methods Totally 33 patients with type 1 diabetes or type 2diabetes were under surveillance of RT-CGMS for 5 d. Capillary glucose values were measured 7 times daily.Correlation coefficient, error grid analysis (EGA), and Bland-Altman analysis methods were used to assess the correlation, accuracy and agreement of RT-CGMS at different stages and in general level; The mean amplitude of glucose excursion (MAGE) and the frequency of glucose excursion ( FGE ) were also calculated. Results ( 1 ) The correlation coefficient of RT-CGMS with capillary glucose values at fasting, postprandial stages, and in general level were 0.94,0.92, and 0.93 respectively( P<0.01 ). (2) EGA showed that 98.82%, 98.39%, and 98.64% of the results fell in the A and B zones and 1. 18%, 1.61%, and 1.36% fell in the D zone respectively at fasting,postprandial stages, and in general level. There is no result fell in C and E zones. ( 3 ) The agreement analysis showed that RT-CGMS readings were in close agreement with capillary glucose values at fasting, postprandial periods, and in general level. (4)The MAGE at fasting, postprandial periods, and in general level were (3.57±2.66), (4.07±3.09), and (4. 02 ±3.04) mmol/L (P>0. 05), (0±0. 5), (3± 1), and( 1 ±3) d for FGE (P<0. 01 ).Conclusion RT-CGMS at fasting stage has higher accuracy than postprandial stage and general level, FGE at fasting stage is higher than postprandial stage and general level.
