Objective To investigate the suicide related psychological status of cancer patients in hospital. Methods 508 cancer patients in the Affiliated- Tumor- Hospital- of- Guangxi- Medical- University were recruited and using the hospital anxiety and Depression Scale (HADS) and Beck Hopelessness Scale (BHS) for evaluating cancer patients′anxiety, depression, hopelessness. According to age, the patients were divided into three groups, comparing the differences in three groups′scores of anxiety, depression, hopelessness. Results Of all the respondents, there were 38.7% (172/445) patients with anxiety, and 26.3% (117/445) patients with depression, and 59.1% (263/445) patients with different degrees of hopelessness. In the comparison of three groups of patients, anxiety scores existed differences (U=7.083,P < 0.05), the average score of anxiety in patients below 40 years was 6.84±3.73, 40-49 years old patients with anxiety average score was 7.17±3.75, 50-60 years old patients with anxiety average score was 6.14±3.79. But depression scores and despair scores had no statistic difference among the three groups(U=2.417 and 0.166, P > 0.05). Conclusions Many people have anxiety / depression in cancer patients, most cancer patients have varying degrees of hopelessness. The health care workers should get attention to these suicide related psychology, take appropriate intervention, in order to avoid the occurrence of hospitalized cancer patients committing suicide.

Objective:To evaluate the role of mitochondrial calcium homeostasis in hyperoxia-induced injury to alveolar epithelial cells typeⅡ(AECⅡ) in rats.Methods:Rat AECⅡcell lines (RLE-6TN) were randomly divided into 3 groups ( n=18 each) using a random number table method: nomoxia group (group C), hyperoxia group (group H), and hyperoxia plus ruthenium red group (group HR). The cell lines were cultured in a conventional incubator for 4 h in group C. The cell lines were incubated in an incubator with 90% O 2 for 4 h in group H. In group HR, ruthenium red 2 μmol/L was added first, and then the cell lines were incubated in an incubator with 90% O 2 for 4 h. After the treatment, the Ca 2+ concentrations in mitochondria were measured using the mitochondrial Ca 2+ specific fluorescent probe Rhod-2-AM, the ROS level was measured using the fluorescent probe DCFH-DA, and the cell morphology and mitochondrial ultrastructure were observed. Results:Compared with group C, the Ca 2+ concentrations in mitochondria and ROS level were significantly increased in H and HR groups ( P<0.05). Compared with group H, the Ca 2+ concentrations in mitochondria and ROS level were significantly decreased in group HR ( P<0.05). Compared group C, the cell volume was reduced, the morphology was shrunken round, the cell arrangement was loose, the mitochondrial double-layer membrane structure was broken, and the mitochondrial cristal fragments were observed in group H. Compared with group H, the cell morphology was significantly improved, and the slight damage to mitochondrial double-layer membrane structure was found, and the structure of mitochondrial cristae was normal in group HR. Conclusion:Mitochondrial calcium homeostasis is involved in the pathophysiological process of hyperoxia-induced injury to AECⅡ in rats.
