Exploring correlations between positive psychological resources and symptoms of psychological distress among hematological cancer patients: a cross-sectional study

Hematological cancer patients experience high levels of psychological distress during diagnoses and intensive treatments. The aim of the present study is to explore the effects of positive psychological resources on depressive and anxiety symptoms in hematological cancer patients. This survey was conducted in a hospital during the period from July 2013 to April 2014. A total of 300 inpatients were recruited and finally 227 of them completed the questionnaires. Questionnaires included demographic and clinical variables, the Center for Epidemiologic Studies Depression Scale, the Self-Rating Anxiety Scale, the Life Orientation Scale-Revised, the General Perceived Self-Efficacy Scale, and the Resilience Scale-14. Results showed that the prevalence of depressive and anxiety symptoms was 66.1 and 45.8%, respectively. Both optimism (β = ?.479, p < .001) and resilience (β = ?.174, p < .05) were negatively associated with depressive symptoms, and optimism (β = ?.393, p < .001) was negatively associated with anxiety symptoms. However, resilience (β = ?.133, p > .05) was not significantly associated with anxiety symptoms, and self-efficacy was not significantly associated with depressive (β = ?.032, p > .05) or anxiety symptoms (β = ?.055, p > .05). The results suggest that hematological cancer patients who possess high levels of positive psychological resources may have fewer symptoms of psychological distress. The findings indicate that enhancing positive psychological resources can be considered in developing intervention strategies for decreasing depressive and anxiety symptoms.     

血液系统恶性肿瘤患者相关疲劳的生物-心理-社会模式探讨

普遍的疲劳感是引起血液系统恶性肿瘤患者治疗及康复过程中生活质量显著降低的主要因素之一。因此如何减少肿瘤相关疲劳逐渐引起了血液病医生的关注。在医学从传统的"生物"模式向新的"生物-心理-社会"模式转变的背景下,本文就如何利用生物心理社会模式分析血液系统恶性肿瘤相关疲劳的病因、机制、评估、干预进行探讨。     

细胞间粘附分子在恶性血液病中的研究进展

细胞间粘附分子（inter-cellular adhesion molecules,Ⅰ-CAMs）属于免疫球蛋白超家族粘附分子,涉及细胞-细胞粘附。它在维护正常组织的稳定、介导炎症细胞的迁移及肿瘤转移等过程中起重要的作用。目前许多研究发现在白血病、淋巴瘤、骨髓瘤等恶性血液病患者中Ⅰ-CAMs高水平表达,并在血液循环中发现其可溶性分子。它们可能在恶性血液病的发生、转移、评估预后中发挥着重要的作用。     

恶性肿瘤皮肤表现

恶性肿瘤皮肤表现可分为肿瘤直接效应与间接效应。直接效应是指恶性肿瘤或其转移灶生长影响周围器官或组织正常功能;间接效应是指恶性肿瘤或其转移灶经复杂生物学效应影响远处器官或组织正常功能,也称为副肿瘤性皮肤病。恶性肿瘤皮肤表现发病率根据原发肿瘤而束同,可能是患者潜在肿瘤首发临床表现,并且与肿瘤复发转移相关。     

低浓度臭氧水与复方利多卡因对血液肿瘤口腔黏膜炎的疗效比较

比较低浓度臭氧水和复方利多卡因溶液漱口治疗血液肿瘤患者化疗所致口腔黏膜炎（OM）的临床疗效.将68例OM患者随机分为试验组和对照组,试验组采用0.5mg/L臭氧水漱口;对照组予以复方利多卡因溶液漱口,采用WHO分级标准每天评估OM的严重程度.结果试验组疗效优于对照组（P=0.001）,总有效率分别为97.0％和73.5％;试验组2级以上OM持续时间明显短于对照组（P=0.000）,分别为（4.30±2.37）天和（8.15±3.07）天;自漱口开始5天内,两组OM严重程度总体变化趋势差异有统计学意义（P=0.008）,第3天开始两组OM等级均逐渐减轻,对照组变化趋势较为平缓.本研究显示低浓度臭氧水漱口可以有效治疗血液肿瘤患者OM.
