Objective: To investigate the effect of losartan on angiotensin II (Ang II) expression and myocardial remodeling in myocardial infarction (MI) rats’ model.
Methods: A total of 32 SD male rats were divided into 4 groups, Sham operation group, MI group, MI with losartan 10mg/(kg·d) group and MI with losartan 20mg/(kg·d). n=8 in each group. MI model was established and the electrocardiogram changes before and after MI were recorded, hemodynamic indexes were detected at 4 weeks after MI, pathological changes of myocardial tissue were examined by HE staining. The myocardial mRNA and protein expressions of ACE2 and Ang II were detected by RT-PCR and Western Blot analysis.
Results: Compared with Sham operation group, MI group showed increased LVMI and decreased LVEF P<0.05;the above changes were getting better in both MI with losartan groups in a dose-dependent manner. The pathological examination presented that MI group had myocardial cell swelling, fracture, hyperplasia and inflammatory cell infiltration, those damages were less in MI with losartan groups in a dose-dependent manner, Sham operation group had no pathological changes. Compared with Sham operation group, the mRNA and protein expressions of Ang II were obviously higher in MI group, P<0.05 and the expressions were decreased in MI with losartan groups in a dose-dependent manner;the mRNA and protein expressions of ACE2 were slightly increased in MI group and the expressions were further increased in MI with losartan groups in a dose-dependent manner.
Conclusion: Losartan could increase ACE2 expression and therefore, inhibit Ang II expression and improve the ventricular remodeling in MI rats’ model.

Objective To study the expressions of apoptotic protease activating factor-1(Apaf-1)and astrocyte elevated gene-1(AEG-1)in colonic carcinoma,and to explore their correlations with the clinical path-ological features. Methods The expressions of Apaf-1 and AEG-1 were detected in 63 colonic carcinoma sam-ples and 30 normal colonic mucosa adjacent to tumor nest by immunohistochemical method,and their correla-tions with clinical features of colonic carcinoma were analyzed. Results The positive expressions of Apaf-1 and AEG-1 in colonic carcinoma were 23. 81%(15 / 63)and 68. 25%(43 / 63),respectively. The positive expre-ssions of Apaf-1 and AEG-1 in normal colonic mucosa were 76. 67%(23 / 30)and 26. 67%(8 / 30),respec-tively. The positive expression rate of AEG-1 was significantly higher in colonic carcinoma than that in normal tissue(χ2 = 14. 192,P = 0. 000). However,the expression of Apaf-1 was signi-ficantly lower in colonic carci-noma than that in normal tissue(χ2 = 23. 497,P = 0. 000). The expression of Apaf-1 was negatively correlated to the expression of AEG-1(r = - 0. 339,P = 0. 007). The expressions of AEG-1 and Apaf-1 were associated with differentiation degree(χ2 = 4. 643,P = 0. 031;χ2 = 12. 034,P = 0. 001)and clinical stage(χ2 = 6. 628, P = 0. 010;χ2 = 8. 246,P = 0. 004),but they were not correlated with age(χ2 = 1. 462,P = 0. 227;χ2 =2. 401,P = 0. 121)and tumor size(χ2 = 0. 333,P = 0. 564;χ2 = 0. 590,P = 0. 442). Conclusion The expression of AEG-1 is up-regulated in colonic carcinoma,but the expression of Apaf-1 is down-regulated,with a significant negative correlation. Apaf-1 and AEG-1 may be closely related to the occurrence and development of colon carcinoma. Therefore,combination detection of Apaf-1 and AEG-1 may be more valuable for the prog-nosis evaluation of colonic carcinoma.
