医学生人格特质与共情能力的相关性研究

目的  测评医学生的共情能力现状，探讨人格特质对其共情能力的影响,为培养医学生的共情能力提供对策。方法  以上海市3所高校临床医学专业学生为研究对象，采用班级整群抽样的方式进行问卷调研。采用杰斐逊共情量表-医学生版（JSPE-S）和大五人格量表（NEO-FFI）分别评估医学生的共情和人格特质。结果  共发放问卷2 020份，回收有效问卷1 958份，有效率为96.93%。医学生的共情能力总分均值为（103.24±14.35）。共情能力总分与大五人格中的“外向性”“开放性”“宜人性”“严谨性”维度呈显著正相关（r=0.154~0.406, P<0.01），与大五人格中的“神经质”维度呈显著负相关（r=-0.175, P<0.01）。分层回归结果表明：“共情重要性”和“大五人格”量表的5个维度进入回归方程。其中，人格因素占可解释方差变异量的16.2%（P<0.01）。结论  我国医学生的共情能力低于国外医学生，重视人格特质的塑造有助于提高其共情能力。     

Mycophenolate Mofetil Use Is Associated with Decreased Risk of Late Acute Rejection in Adult Liver Transplant Recipients

Mycophenolate mofetil (MMF) used in a triple-drug regimen has been shown to decrease acute rejection rates, compared to a double-drug regimen. The impact of MMF on late acute rejection (LAR) episodes has not been well described. To investigate the risk of LAR (rejection > or = 6 months post-transplantation) data from the Scientific Registry of Transplant Recipients (SRTR) were used. We studied adult primary liver transplant recipients transplanted between June 1, 1995, and April 30, 2004, with hepatitis C virus (HCV) (n = 3356), hepatitis B virus (HBV) (n = 550) or a nonviral (n = 5740) primary cause of liver disease who were recorded as receiving continuous 3-(MMF + Tacro + steroids) versus 2-drug (Tacro + steroids) therapy for at least 6 months immediately post transplantation. Kaplan-Meier analysis showed significantly lower LAR rates 4 years post-transplant in 3- versus 2-drug HCV, HBV and nonviral disease patients. Multivariate regression confirmed 3- versus 2-drug therapy to be associated with a decreased risk of LAR. Late graft survival was significantly lower at 4 years post-transplant for patients with LAR 6-12 months post-transplantation versus patients with early rejection (78.0% vs. 87.0%, p < 0.001) and no rejection (88.1%, p < 0.001). Three-drug versus 2-drug therapy for a minimum of 6 months may offer a better treatment strategy to avoid the consequences and expense of LAR episodes.     

Bombesin improves survival from methotrexate-induced enterocolitis.

OBJECTIVE: The authors determined whether bombesin could improve survival from methotrexate (MTX)-induced enterocolitis. SUMMARY BACKGROUND DATA: Bombesin prevents gut mucosal atrophy, which is produced by feeding rats an elemental diet. Administration of MTX produces a lethal enterocolitis in rats fed an elemental diet. METHODS: On treatment day 0, 60 rats were divided randomly into three groups and fed an elemental diet (Vivonex TEN, Sandoz, Minneapolis, MN) as the only source of nutrition. Groups were subdivided further to receive either saline or bombesin (10 micrograms/kg, subcutaneously, three times a day) beginning either on day 0 or day 14. Methotrexate (20 mg/kg, intraperitoneally) was given to all rats 14 days after the start of an elemental diet. RESULTS: Bombesin prevented the mucosal atrophy in the ileum produced by the elemental diet and significantly decreased mortality in rats given MTX (whether given as a pretreatment or at the time of MTX administration). CONCLUSION: Bombesin significantly improved survival in a lethal model of MTX-induced enterocolitis, possibly by maintaining gut mucosal structure. Administration of bombesin to patients receiving chemotherapy may be clinically useful in preventing the severe enterocolitis induced by various chemotherapeutic agents.     

大学生心理素质与思想品德发展的关系

研究大学生心理素质与思想品德发展的关系，目的在于分析、发现个体在接受教育过程中的心理运动规律，从而提高思想教育的实效性。本文从马克思主义认识论和实践论的观点出发，依据教育心理学的原理，探讨了心理健康教育与思想品德教育的内在联系和相互作用，提出良好的心理素质是大学生思想品德发展的基础的观点。认为品德的形成与人的心理活动息息相关，个体如果没有良好的品德，将影响其心理素质的完善；同样，没有健全的心理素质，思想品德也不能得到很好的发展。只有思想品德教育与心理健康教育协调发展，共同作用，才能收到良好的教育效果。
