Objective To investigate renal dialysis patients' resilience and influencing factors for clinical teaching. Methods Connor-Davidson resilience scale(CD-RISC),simplified coping style questionnaire (SCSQ), perceived social support scale (PSSS) and positive and negative affect scale (PANAS) were used for a survey of 160 renal dialysis patients in Xinan Hospital and Xinqiao Hospital (156 valid questionnaires) and the questionnaire information was put into the computer by the two-input mode and was made the questionnaire data analysis, single factor analysis and variance and re-gression analysis of by SPSS 18.0. Results Renal dialysis patients' resilience has no significant differ-ence in gender, frequency of kidney dialysis and kidney dialysis time (P>0.05), but resilience and positive coping scores of the age group between 31 to 40 were significantly higher than those of the group between 41-50 group(P=0.000). Taking the education background into consideration, resilience and positive coping scores of junior high school or above education were significantly higher than those of primary school education (P=0.000,P=0.000). Positive emotion, positive coping, and social support were positively correlated with resilience and negative emotions were negatively correlated with resilience in linear regression analysis. Conclusion Kidney dialysis patients who are over the age of 40 and less educated may have lower resilience, and less positive coping, more prone to nega-tive emotions, which is not conducive to the rehabilitation and treatment of disease. For kidney dialysis patients, improving their positive response, perceived social support and positive mood, and reducing their negative emotions are beneficial to the improvement of their resilience.

OBJECTIVE:To observe the clinical efficacy and safety of piperazine ferulate combined with glutathione in the treatment of diabetic nephropathy. METHODS:80 patients with diabetic nephropathy in our hospital were divided into observation group and control group according to random number table,with 40 cases in each group. Both groups was given general treatment as blood glucose,blood lipid and blood pressure control. Control group was additionally given Reduced glutathione tablets 400 mg, tid,on the basis of general treatment. Observation group was additionally given Piperazine ferulate tablets 100 mg,tid,on the ba-sis of control group. Both groups were treated for 12 weeks. The fasting plasma glucose(FPG),2 h postprandial plasma glucose(2 hPG),blood pressure,blood lipid,serum creatinine (Scr),blood urea nitrogen (BUN),24 h urinary total protein and albumin, urine β2 microglobulin(β2-MG)and N-acetyl-β-glucosaminidase(NAG)of 2 groups were detected before and after treatment. The occurrence of ADR was observed. RESULTS:Before treatment,there was no statistical significance in FPG,2 hPG,blood pres-sure,blood lipid,Scr,BUN,24 h urinary total protein and albumin,urine β2-MG and NAG between 2 groups(P>0.05). After treatment,above indexes of 2 groups were improved significantly,and the observation group was better than the control group, with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:In the treatment of diabetic ne-phropathy,piperazine ferulate combined with glutathione can improve blood glucose,blood pressure,blood lipid levels and renal function with good safety.

Panax ginseng is one of the most important traditional Chinese herbal medicine, soil borne diseases influenced the yield and quality severely. In our previous work, endophytic Bacillus subtilis ge25 strain was isolated from ginseng root, and which showed significant antagonistic activity against several most destructive ginseng phytopathogens. In the present work, crude protein and lipopeptid extracts were prepared from LB and Landy supernate by salting out, acid precipitation methods respectively. The antagonistic activity of crude extracts and stability to temperature and protease digestion were examined by ginseng phytopathogen Alternaria panax. Results showed that, the antagonistic activity of crude protein extracts from LB culture was complete and partially lost when treated by high temperature and proteinase K. However, crude lipopeptid from Landy culture showed significant stabile antagonistic activity to them. Acid-hydrolyzation and TLC-bioautography analysis showed, that the crude lipopeptide contained at least one cyclic lipopeptide. In consideration of the stability and perfect antagonistic activity of ge25, further researches will promote the biocontrol of ginseng diseases in the field.

·AIM: To detect the effect of CTGF on the apoptosis in the diabetic retina with small interfering RNAs (siRNA) targeting with CTGF. ·METHODS: A total of 60 rats were divided into six groups including control group, diabetic 4,8,12,16 weeks group, and interference group. Diabetic rats were induced by STZ intra-peritoneal. At 4, 8, 12, 16 weeks after diabetic setting up, retinas were obtained from control, diabetic rats and diabetic animals treated by intravitreal injection of CTGFsiRNA to suppress the expression of CTGF mRNA. Retinal cells apoptosis was detected by Tunnel staining and mRNA expression of CTGF was analyzed by RT-PCR.·RESULTS: The levels of CTGF and the apoptosis in the retinas of diabetic rats were significantly higher than those in the controls. Apoptosis occurred at 4 weeks after a diabetic model setting up, became serious with the diabetes developing, while CTGF elevated at 8 weeks. The cell apoptosis counts increased to 25.8cells/mm2 at 24 weeks of diabetes. SiRNA-mediated inhibition of CTGF mRNA resulted in a significant decrease in apoptosis. Significant correlations were found between CTGF and apoptosis in the retina.·CONCLUSION: These results suggest that CTGF might be involved in retinal cells apoptosis which is a characteristic of early diabetic retina. siRNA targeting CTGF seems to have the advantage of ameliorating retinal cells lost.
