AIM: To study effect of benazepril (an ACE inhibitor) on expression of insulin receptor (IR) and its substrate-1(IRS-1) protein in renal tissue cell membrane in diabetic rats. METHODS: The rats were randomly divided into following groups: control (n=6), streptozotocin induced diabetic (n=7) and diabetic treated with benazepril (n=7). Body weight, kidney weight and kidney weight/body weight were observed after 4 weeks of treatment. ACE activities in plasma, renal tissue were measured by the fluorimetric assay. The expressions of IR and IRS-1 protein were determined by Western blot analysis in renal tissue cell membrane. RESULTS: After 4 weeks of treatment, benazepril significantly ameliorated kidney hypertrophy in diabetic rats. ACE activities in plasma, renal tissue were redunced by approximately 92.00% and 88.77%, respectively. Western blot analysis showed that the expressions of IR and IRS-1 protein were increased by 2.1 and 1.5 folds in renal tissue cell membrane in diabetic rats. However, benazepril reduced expression of IR and IRS-1 protein by 45.74% and 47.66%, respectively. CONCLUSIONS: Increased expression of IR and IRS-1 protein might be related to abnormally active glucose metabolism in diabetic rat kidney. Down-regulation of expression of IR and IRS-1 protein might be one of important machnisms of Benazepril nephroprotection on diabetic rats.

AIM To study effects of ACE inhibitor on the ex pression of GluT4 mRNA and protein in diabetic rat heart. METHODS The following groups of rats were randomly designed: control rats, diabetic ra ts and diabetic rats treated with benazepril (an ACE inhibitor). After 4 weeks o f treatment, ACE activities were determined by fluorimetric assay in plasma and heart; Myocardial GluT4 mRNA expression were measured by Northern blot analysis; GluT4 protein expression were measured by Western blot analysis. RESULT S After 4 weeks of treatment, there was a significant increase in myocard ial ACE activities despite a trend toward reduce in plasma activitics, ACE activ ities were inhibited by 92 1%, 89 0% in plasma and heart, respectively; Northe rn blot analysis revealed that the expression of GluT4 mRNA was reduced in diabe tic rat heart by 40%, and treatment with benazepril did not prevent the diabetes -induced reduction of GluT4 mRNA; However, Western blot analysis revealed that benazepril did prevent the diabetes-induced reduction of GluT4 protein in cell membrane of diabetic rat heart. CONCLUSION Benazepril could significantly suppress ACE activities in diabetic rat heart, bu t it did not influence the expression of the myocardial GluT4 mRNA. However, it did prevent the diabetes-induced reduction of GluT4 protein in cell membrane of rat heart.

Objective:To understand the responsiveness of community health service institutions in Henan Province. Methods:This research collected information through questionnaire investigations. The object of the investigations is key informants familiar with community health service institutions. Various dimensions of responsiveness within Henan province community health service institutions are determined through a multiple-input pecking order graph. The fuzzy comprehen-sive evaluation method is used to evaluate the level of responsiveness. Responsiveness inequality index is used to measure the distribution of reactions. Results:A total of 431 valid key informants were surveyed. The various dimensions of the questionnaire of Cronbach alpha coefficient was greater than 0. 623;the total scale of the Cronbach alpha coefficient was 0. 850;the correlation coefficient of each dimension of test-retest reliability were greater than 0. 907. The levels of responsive-ness and distribution index were 8. 33 and 0. 2744, respectively;each dimension by order of importance:timely attention>dignity>infrastructure>communication>confidentiality >social support >selective >autonomy. Approximately 50% of key informants considered that vulnerable groups in community health service institutions were sometimes or often treated unfairly. Conclusion:Key informants considered the responsiveness level of overall higher community health service institu-tions in Henan Province was high, and the distribution of responsiveness was relative equilibrium. However, there is a large shortage of infrastructure, privacy protection, doctor-patient communication, etc.
