RESUMO
The convenience of "no installation, available at your fingertips" of the WeChat small program makes it unique in the application of mobile terminal auxiliary experimental teaching. In order to optimize the assessment system and improve the quality and outcomes of experimental teaching, a self-designed WeChat small program was used to assist the development of the process assessment system. This system was applied to the teaching practice of "Experiment of Inorganic Chemistry" course for the first-year undergraduates majored in Biological Engineering, with the aim to promote teaching and learning by assessment. The results showed that course scores of the students who used this small program were superior to the control group and the correlation between the process assessment and final examination results was significant. These results indicated the WeChat small program assisted process assessment could effectively improve the learning outcomes of students, enable them to grasp the knowledge of Experiment of Inorganic Chemistry efficiently. The results of the questionnaire for the teachers and students also showed a high recognition of the WeChat small program assisted teaching.

Objective To observe the effect of beraprost sodium on elderly patients with type 2 diabetic nephropathy (DN) and to observe the change of the plasma vascular endothelial growth factor(VEGF) and endothelin(ET-1) level.Methods The levels of plasma VEGF and ET-1 in the 27 cases of type 2 diabetes without nephropathy and 48 cases with type 2 diabetic nephropathy were measured.The possible role of VEGF and ET-1 in diabetic nephropathy was explored.48 cases of type 2 diabetic nephropathy patients were randomly divided into 2 groups:the conventional treatment group and beraprost sodium treatment group.The changes of VEGF and ET-1 level in the 2 groups before and after the treatment were measured.Results The plasma VEGF and ET-1 levels were significantly higher in type 2 diabetic nephropathy patients than in type 2 diabetes patients without nephropathy(P ＜0.01).Compared with the control group,beraprost sodium significantly reduced the plasma VEGF and ET-1 levels in patients with diabetic nephropathy(P ＜ 0.05),and also reduced urinary albumin excretion rates (UAER) significantly (P ＜ 0.05).Conclusions The increasing level of VEGF and ET-1 plays an important role in the onset of diabetic nephropathy.Beraprost sodium can correct the balance of the plasma VEGF and ET-1 in treatment of patients with diabetic nephropathy,improves the endothelial function in diabetic nephropathy,decreases urine protein,and plays a protective role in diabetic nephropathy.
RESUMO
Objective To study the effect of atorvastatin on serum cystatin C and urinary microprotein in patients with early diabetic nephropathy (DN).Methods Sixty-eight cases of early DN were divided into control group and observation group with 34 cases each by random digits table,the control group was treated with the conventional treatment,the observation group was treated with atorvastatin on the basis of conventional treatment,then blood lipids,serum cystatin C,urinary albumin excretion rate (UAER),microalbuminuria( MAU ),α1-microglobulin(MG),β 2-MG between the two groups were compared.Results After intervention,the levels of total cholesterol (TC),triacylglycerol (TG),serum cystatin C,UAER,MAU,αt 1-MG,β 2-MG were significantly decreased compared with those before treatment in the observation group [ (4.32 ± 1.26) mmol/L vs.(5.65 ± 1.38 ) mmol/L,( 1.67 ± 0.64) mmol/L vs.(2.53 ± 0.96 ) mmol/L,( 1.29 ± 0.38 ) mg/L vs.( 1.74 ± 0.51 ) mg/L,(61.09 ± 18.45 ) μ g/min vs.( 86.42 ± 21.34) μ g/min,( 5.73 ±4.81) mg/L vs.(23.16 ±9.73) mg/L,(1.41 ± 1.21) mg/L vs.(4.76 ± 1.24) mg/L,(1.21 ±0.13) mg/L vs.(2.58 ± 0.26) mg/L ] (P ＜ 0.01 or ＜ 0.05 ).In the control group,the levels of TC,TG,serum cystatin C were lower than those before treatment,but there were no significant differences (P＞0.05),but the levels of UAER,MAU,α 1-MG,β 2-MG had significant differences compared with those before treatment (P ＜ 0.01or ＜ 0.05 ) and the same time of the observation group (P ＜ 0.05 or ＜ 0.01 ).Conclusion Atorvastatin can significantly reduce serum cystatin C and urinary micro-protein levels in patients with early DN,which plays an important role in kidney protection.
RESUMO
Objective To observe the effect of tripterygium glycosides combined with prednisone in treatment of purpura nephritis.Methods 51 patients with purpura nephritis were selected and treated by tripterygium glycosides (1.5～2.0mg/kg) combined with prednisone(1.5～2.0mg/kg) ,three times every day.The total course was 6 to 9 months.Before and after the treatment, the five indicators of bleeding and coagulation, urine protein, occult blood changes and drug side effects and recurrence after drug withdrawal were observed.Results The high coagulation of the blood was improved,and the renal function of 94.1%children recovered.Only 6 cases had little complication and only 1 case had recrudescence 1 year after leaving hospital.Conclusion Tripterygium glycosides combined with prednisone was effective in treating children with purpura nephritis.
