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.
4.An initial study on serum CA125 in diagnosis to lung cancer
China Oncology 2001;0(02):-
35u/ml as positive limit, the sensitivity of CA125 for diagnosis of lung cancer is 53.6%. There was no significant difference between stage Ⅰ,Ⅱ lung cancer and benign, healthy groups, but the level of serum CA125 of stageⅢ?Ⅳ was higher than control groups. Thirty eight of forty lung cancer patients with higher CA125 level dropped to normal after therapy. Conclusions:Serum CA125 has high diagnosis value in lung cancer. It can be a vital index in lung cancer staging and prognosis.

Objective To observe the effects of hysteroscopic transcervical resection of endometrium combined with levonorgestrel-relea-sing intrauterine system in the treatment of adenomyosis. Methods Clinical data of 62 cases with adenomyosis from January 2009 to January 2011 were randomly divided into 2 groups with 31 cases each. The observation group was given hysteroscopic transcervical resection of endo-metrium ( TCRE) combined with levonorgestrel-releasing intrauterine system( LNG-IUS) ,the control group was given LNG-IUS. All patients were followed up in 0,1,3,6,12 months after treatmenting with LNG-IUS. The menstrual blood volume,score of VAS,volume of uterus, CA125 and the levels of serum reproductive hormone were analyzed before treatment and after treatment. Results After the therapy,the cur-ative effects of controlling menorrhea were improved and the the observation group was significantly better than the control group(P<0. 05). The VAS scores were significantly decreased after the therapy in the two groups, but there was no significant difference between the two groups (P<0. 05). The level of CA125 in the observation group was significantly lower than the pretherapy,which was better than that in the control group (P<0. 05). There was no significant difference between the two groups in the volume of uterus after treatment and the levels of serum FSH,LH,E2 and P(P>0. 05). Conclusion It is exact effect to treat adenomyosis by TCRE combined with LNG-IUS,which can prevent dripping bleeding induced by application of LNG-IUS effectively.
