Objective To investigate the effect of miRNA-1 on the cardiomyocyte apoptosis in rats. Methods MicroRNA-1 mimics was transfected into the cultured H9c2 cell line (miRNA-1 group). Cells transfected with random miR-NA fragment was used as negative control group. The cell apoptosis was evaluated by FCM assay. MTT assay was used to de-tect the cell viability. The expression level of miRNA-1 was detected by real-time PCR. The expression levels of Bcl-2 mRNA and protein were detected by real-time PCR and Western blot assay. Results Compared with normal and negative control groups, the expression level of miRNA-1 was significantly higher in H9c2 cardiomyocytes, the apoptosis rate was in-creased, the cell vitality and Bcl-2 expression level were significantly decreased after transfection of miRNA-1 mimics. Conclusion miRNA-1 mimics can up-regulate miRNA-1 level, inhibit proliferation and induce cardiomyocyte apoptosis.

Objective To investigate the relationship between homocysteine(Hcy)and blood uric acid(UA)in the patients with type 2 diabetes mellitus(T2DM)complicating hypertension.Methods 85 patients with T2DM complicating hypertension were se-lected as the groupⅠ,78 patients with simple T2DM as the group Ⅱ and 74 individuals with healthy physical examination as the group Ⅲ.Hcy,UA,TC,TG and HDL-C were measured in all the subjects.Results Compared with group Ⅲ(control),the levels of Hcy,UA,TC and TG in the group Ⅰand groupⅡwere significantly increased(P <0.05),but the level of HDL-C was significantly decreased(P <0.05).Compared with the group Ⅱ(T2DM),the levels of Hcy,UA,TC and TG in the group Ⅰwere significantly in-creased(P <0.05 ),but the level of HDL-C was obviously decreased,the difference had statistical significance (P <0.05 ).There was good positive correlation between the Hcy level and the UA level in the patients with T2DM complicating hypertension (r =0.658,P <0.05).Conclusion The levels of Hcy and UA are significantly increased in the patients with T2DM especially complica-ting hypertension.High Hcy and high UA are the important risk factors of T2DM complicating cardiocerebrovascular diseases.

Objective: To explore whether relieving effect of Ginsenosides-Rb1 (Gs-Rb1) on chronic heart failure (CHF) induced by adriamycin is related to improving levels of tumor necrosis factor (TNF) receptor (TNFR) and ligand TNF-α or not. Methods: Adriamycin-induced CHF model rats were randomly divided into adriamycin group (n=15, received adriamycin 1 μmol/L) and Gs-Rb1 group (n=17, received Gs-Rb1 70 mg•kg-1•d-1 based on adriamycin group), another 10 healthy Wistar rats were selected as normal control group. Meanwhile, cultured cardiomyocytes of neonatal rats were accordingly divided into normal control group, adriamycin group and adriamycin+Gs-Rb1 group. After intervention, echocardiography, levels of TNFR/TNF-α mRNA and protein were measured and compared among three groups. Results: 1. In vivo: Compared with normal control group TNFR-1 [protein（0.13±0.02）kDa, mRNA（0.19±0.05）bp]，TNFR-2[protein（0.24±0.01）kDa, mRNA（0.13±0.02）bp]，TNF-α [protein（0.11±0.01）kDa, mRNA（0.26±0.05）bp], the levels of TNFR-1 [protein（0.67±0.04）kDa,（0.51±0.04）kDa；mRNA（0.81±0.03）bp，（0.49±0.05）bp]，TNFR-2 [protein（0.61±0.05）kDa, （0.47±0.03）kDa，mRNA（0.28±0.03）bp，（0.18±0.04）bp] and TNF-α [protein（0.28±0.04）kDa, （0.20±0.03）kDa， mRNA（0.67±0.05）bp，（0.45±0.04）bp] significantly rose（P<0.05 or <0.01） in adriamycin group and Gs-Rb1 group; and those levels of TNFR-1, TNFR-2, TNF-α protein and mRNA of Gs-Rbl group were significant reduction than those of adriamycin group; 2. In vitro: The results were similar, those of adriamycin group and Gs-Rb1 group were also significant rise than those of normal control group（P<0.05 or <0.01），those of Gs-Rbl group were significant reduction than those of adriamycin group（P<0.05 or <0.01）. Conclusion: TNFR/TNF-α expression may play a certain role in the process of adriamycin-induced CHF; improving effect of Gs-Rb1 on adriamycin-induced CHF may be related to regulation of TNFR/TNF-α.

Objective To investigate the clinical autopsy results of patients died of cardiovascular disease or other disease complicated with cardiac damage. Methods Complete autopsy was performed on 86 cases with uncertain cause of death. Through integrating clinical diagnosis and treatment with gross autopsy findings and microscopic observations, 86 autopsies were determined the major cause of death. Results In 86 autopsies, 69 cases were heart disease. Differences between pathological diagnosis and clinical diagnosis were compared. Twenty-seven cases were cardiac deaths, with diagnosis accrodance rate of 81. 5%. Fortytwo cases died of non-cardiac disease but complicated with heart disease or involving the heart which accelerated the death in patients, with accordance rate of 78.6%. Conclusion Scientific and correct performance of autopsy was important to determine the causes of death, to promote development of related disciplines and to improve the diagnosis and treatment of the diseases.
