目的 检测血管内皮生长因子（VEGF）、白细胞分化抗原34（CD34）及CXC趋化因子受体4（CXCR4）在转移性鼻咽癌患者鼻咽部肿瘤组织中的表达，探讨它们与鼻咽癌各种临床病理因素的关系以及它们之间的相互联系。 方法 采用免疫组织化学链霉素抗生物素蛋白-过氧化物酶连结法检测2003年3月－2009年5月35例转移性鼻咽癌患者VEGF、CD34及CXCR4在鼻咽部肿瘤组织中的表达情况，结合患者临床病理特征进行分析。 结果 转移性鼻咽癌患者鼻咽部肿瘤组织中的VEGF及CXCR4阳性表达率分别为62.9%（22∕35）和42.9%（15∕35），CD34计数为11～92，平均43.2 ± 20.5。无肺转移较有肺转移的患者VEGF的阳性表达率高（78.9%、43.8%，P=0.043），多器官转移较单器官转移的患者CXCR4的表达强度高（62.5%、26.3%，P=0.044）。 结论 VEGF表达阳性的患者易发生肺转移；CXCR4强表达的患者易发生多器官转移。
ObjectiveTo investigate the estimated prevalence of depression and its associated factors among inpatients in the Department of Oncology in general hospitals. MethodsOn October 29th, 2013, we surveyed all hospitalized patients from the Department of Oncology in West China Hospital, Sichuan University. The questionnaire on patients’ demographic characteristics and the Patient Health Questionnaire-9 (PHQ-9) were combined to form one questionnaire to investigate the incidence of depression in hospitalized patients in general hospitals and its influencing factors. ResultsWe gave out 546 questionnaires and retrieved 528 with a retrieval rate of 96.6%. Seven questionnaires had 15 or more empty items and were deleted. The final number of valid questionnaires was 521, with a validity rate of 95.4%. The estimated prevalence of depression among inpatients from the Department of Oncology was 32.8% (171/521). Risk factors for depression in patients in the Department of Oncology included female gender [OR=1.550, 95%CI (1.034, 2.325), P=0.034] illiterate and primary school education [OR=2.534, 95%CI (1.329, 4.832), P=0.005] and annual household income lower than 10 000 RMB [OR=1.850, 95%CI (1.056, 3.243), P=0.032]. A total of 135 patients had suicidal risks, among whom 90 (52.6%) had depression, and Spearman correlation analysis showed that suicidal risk was moderately and positively correlated with PHQ-9 scores (r=0.558, P<0.001). ConclusionsThe estimated total prevalence of depression is high in hospitalized patients in the Department of Oncology, especially in female, low educational level and low family income patients. We must pay more attention to the mental health of cancer patients, evaluate depression and suicidal tendency carefully and provide psychological service timely.
