Objective To investigate the expression of apoptosis regulating protein Bcl-2 and Bax,and the spontaneous apoptotic index(AI) in malignant mesothelioma,and their relationship to the survival time of patients.Methods Hematoxylin-eosin and immunohistochemical stainings were used for the sections of paraffin embedded tissues of 79 specimens of malignant mesothelioma.The terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL) was used to identify the apoptotic tumor cells.Results The age of the patients with malignant mesothelioma ranged from 11 to 79 years.The peak incidence of malignant mesothelioma was at the age of 40-50 years.The ratio of male to female was 1.47∶1.The survival time of the 79 cases was between 5 and 160 months,and the medial survival time was 23 months.According to histological pictures,these tumors were diagnosed as epithelioid type(51 cases),mixed type(8 cases) and sarcomatous type(20 cases).The tumor spontaneous apoptotic index(AI) was 0.14%-6.9%.The survival time of the patients with higher AI was significantly shorter than those with lower AI(P

0.05).Conclusions HPC has protective effect on neonatal rats with cerebral hypoxia-ischemia,but it does not have obvious effect on NGB.

Objective To evaluate the methylation status of RASSF2A in epithelial ovarian cancer (EOC) tissues and plasma, and to explore the correlations in two kinds of samples with clinicopathological characteristics. Methods The frequency of methylation of the RASSF2A gene in tissues and corresponding plasma samples from 60 EOC patients, 20 patients with benign ovarian tumors and 10 patients with normal ovarian tissues were detected respectively. The methylation-specific PCR was used to determine the methylation status. Results The frequency of aberrant methylation of RASSF2A was 58.3% (35/60) in EOC tissues and 43.3%(26/60) in corresponding plasma samples respectively, however, such hypermethylation was not detected in the benign ovarian tumors and normal ovarian samples, and there was significant difference between them (P<0.05). Besides, RASSF2A methylation levels in serum of EOC patients correlated reasonably well with methylation status in tumor samples (r=0.739, P=0.000). No significant differences were observed between the promoter hypermethylated status of the RASSF2A and clinicopathological characteristics (P>0.05). Conclusions The promoter methylation of RASSF2A gene is an early and frequent epigenetic event in EOC. Detection of promoter hypermethylation in plasma specimens can help the early diagnosis of EOC.
