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。     

Sperm chromatin integrity in young men with no experiences of infertility and men from idiopathic infertility couples

Damage to the genetic component of spermatozoa seems to play the main role in a majority of cases where current approaches fail to reveal the specific cause of male infertility. In this study, we compared semen quality in men assigned to two defined groups: men from couples with unexplained infertility – idiopathic infertility (A) and young men with no experiences of infertility (B). All samples were examined by standard ejaculate analysis and sperm chromatin structure assay (SCSA). Sperm chromatin damage was significantly higher in men from group A than in those from group B. Similar results were obtained by comparison of men from group A (all men were normozoospermic) with normozoospermic men from group B. According to these results, we can suppose that chromatin disorders may be the causal factor of subfertility or infertility in some of these men. No evidence for a strong association between chromatin disorders and standard parameters of ejaculates was found. We failed to confirm a relationship between smoking and sperm quality in men from any of the investigated groups. SCSA is a method that facilitates the identification of infertile men who otherwise show normal semen variables.     

The relational underpinnings of quality internal auditing in medical clinics in Israel

Internal auditing is a key mechanism in enhancing organizational reliability. However, research on the ways quality internal auditing is enabled through learning, deterrence, motivation and process improvement is scant. In particular, the relational underpinnings of internal auditing have been understudied. This study attempts to address this need by examining how organizational trust, perceived organizational support and psychological safety enable internal auditing. Data collected from employees in medical clinics of one of the largest healthcare organizations in Israel at two points in time six months apart. Our results show that organizational trust and perceived organizational support are positively related to psychological safety (measured at time 1), which, in turn, is associated with internal auditing (measured at time 2).     

Quantification of Basal and Stimulated ROS Levels as Predictors of Islet Potency and Function

We have developed a luminol-based assay using intact islets, which allows for quantification of reactive oxygen species (ROS). In addition, an index capable of characterizing metabolic and mitochondrial integrity prior to transplantation was created based on the capacity of islets to respond to high glucose and rotenone (mitochondrial respiratory chain complex I inhibitor) by production of ROS. To validate this assay, lipid peroxidation and antioxidative defense capacity were evaluated by detection of malondialdehyde (MDA) levels and glutathione peroxidase activity (GPx), respectively. Also, flow cytometric analyses of ROS (dihydroethidine), apoptosis (Annexin V, active caspases), necrosis (Topro3), and mitochondrial membrane potential (JC-1) were done in parallel to correlate with changes in luminol-measured ROS. ATP/ADP ratios were quantified by HPLC and the predictive value of ROS measurement on islet functional potency was correlated with capacity to reverse diabetes in a streptozotocin-induced diabetic NOD.scid mouse model as well as in human transplant recipients. Our data demonstrate that levels of ROS in islets correlate with the percentage of apoptotic cells and their functional potency in vivo. The ROS indices following glucose and rotenone exposure are indicative of metabolic potency and mitochondrial integrity and can be used as surrogate markers to evaluate the quality of islets prior to transplantation.     

2004年聊城市东昌府区2类食品卫生质量抽检结果分析

[目的]了解东昌府区糕点、面包类与饼干类食品的卫生质量状况。[方法]对2004年在东昌府区城区及周边16个乡镇采集的糕点、面包类和饼干类样品检测资料进行分析。[结果]检测样品1 180份,合格率为84.41%。其中,糕点、面包类样品合格率为83.35%,城区合格率高于乡镇,生产加工单位合格率高于销售单位(P<0.01);饼干类样品合格率为87.30%,城区与乡镇、生产加工单位与销售单位样品的差异无统计学意义(P>0.05)。不合格项目是菌落总数、大肠菌群、酸价和过氧化值。[结论]饼干类的合格率较高,糕点、面包类的合格率较低;销售单位糕点、面包类的卫生质量较差,乡镇样品的卫生问题较为突出。     

病理技术质量控制的探讨

病理技术是病理学诊断不可分割的一部分,正确的染色结果是病理诊断的重要依据之一.病理技术的规范与否,制片质量的好坏很大程度上影响病理医生作出正确的病理诊断.     

急性心肌梗死患者睡眠质量的临床研究

目的 对急性心肌梗死（Acute Myocardial Infarction，AMI）患者睡眠状况进行观察，研究其规律性及与心肌梗死发生、转归的关系。方法 对75例AMI患者分别进行睡眠质量观察和评估。结果 AMI患者按睡眠质量总分分组后，高得分组（≥5．06分，40例）的平均住院时间、梗死面积、合并症数目均明显高于低得分组（〈5．06分，35例），而低得分组的日常生活能力得分却明显高于高得分组（P〈0．05）。结论 AMI患者有明显的睡眠质量下降，并影响其梗死面积、合并症、日常生活活动能力和住院时间。     

对新调入护士进行专科知识教育的体会

目的探讨如何对新调入肿瘤科的护士进行专科教育的有关问题。方法帮助新护士尽快适应工作环境，进行必要的专科知识教育和专科技术传授，熟练掌握肿瘤病人的心理特点及健康教育技巧。结果新护士在调入1个月后能单独完成本职工作，未发生差错和事故，同事对新调入护士评价好，病人满意。结论护士长对新调入护士有目的地进行专科理论知识教育和专科技术操作传授，言传身教，对尽快提高新调入护士的工作能力，确保护理质量起着重要的作用。     

学生课堂教学质量评价问题浅析

综合分析河南中医学院近三年以来学生课堂教学质量评价反馈的信息，认为引发课堂教学评价偏差的人为因素有评价者的能力水平、责任心、情感倾向。其对策为：改变教师的被动地位，进一步修订评价体系，加强对组织评价者的培训，强化临床课的教学，进一步提高学生的认识，跟踪调查课堂教学质量评价。
