北京、广州、上海城市居民营养知识、态度、行为的调查

对北京、广州和上海三大城市随机抽取的９６５名年龄在２０～５０岁的城市居民进行有关营养知识、态度和行为（Ｋ－Ａ－Ｐ）的调查。结果显示，三地区调查对象的营养知识水平不高。营养知识的得分与其自身受教育程度有相关性（ｒ＝０．３０１１，Ｐ＜０．０１）。年龄在３５岁以上的对象，营养知识的得分高于年轻人；三地区调查对象对营养知识的获取，合理的膳食模式，卫生的饮食习惯均持有积极、肯定的态度。食物消费频度调查结果表明，米／面、肉／禽、蔬菜、水果、奶及奶制品的消费量较高。此外，８９．５％，７８．８％和４７．８％的调查对象分别选择报纸、电视、广播作为其主要营养信息来源。本次调查为将来的营养宣教的内容和方法提供依据。     

Coronary permeability and left ventricular function following thrombolytic therapy

We study 40 patients, 55 +/- 7 years old with acute myocardial infarction treated early by thrombolytic therapy (20 STK and 20 rt-PA). All patients were angiographically studied in the following conditions: 1) baseline, before initiating therapy. 2) Three hours after treatment. 3) Twenty four hours later. 4) Before discharge. The infarct related artery was patent 24 hours after treatment in 31 patients (78%); five of them were patent before treatment, and we observed an early reperfusion in 20 patients (57%) and late reperfusion in 6 patients (17%). The number of patients with angiographic evidence of intraluminal thrombus decreased progressively through conditions while the grade TIMI of coronary perfusion increased in the absence of reocclusion. Final regional wall motion of infarct related myocardial zones and their degree of recovery were significantly higher in recanalized patients, as compared with non-reperfused patients. Similarly, left ventricular functional recovery was higher in patients with antegrade of collateral flow to the infarct area, as compared with totally occluded patients.     

家庭护理的危险因素分析及对策

随着人们法制观念的增强,对自身合法权益的维护越来越重视,对医疗护理质量的需求也越来越高。近年来,人民生活水平的不断提高,患心脑血管疾病、肿瘤等慢性疾病者增多,护理需求量增加,需要护理人员从医院走向社区,走入家庭,为个人、家庭、社会提供直接、连续、全面、方便、快捷、经济、优质的家庭护理服务,以满足社区居民的需求。我院于2002年5月开设了家庭护理,现已开展了12项服务内容,共对27例病人(149例次)实施家庭护理服务,护理服务对象平均年龄为74.8岁,其中脑梗死23例,多伴有偏瘫、失语,合并有高血压、糖尿病等疾病;恶性肿瘤2例;肾衰竭…     

失去肝动脉血液供应后大鼠肝门部胆管周围血管丛变化的三维构像研究

目的 探讨完全失去肝动脉血液供应后，大鼠肝门部胆管周围血管丛（PBP）的形态学变化。方法 将SD大鼠随机分为两组，对照组仅游离胆总管、门静脉、腔静脉和肝总动脉，不做切断；实验组结扎肝动脉，并切断肝十二指肠韧带除门静脉以外的其它组织，阻断其它侧支血管对肝门部胆管的血液供应。术后应用计算机对大鼠肝门部组织切片进行PBP三维可视化构建，并对PBP内层微血管进行定量分析，对胆管壁组织进行病理学检查。结果 实验组肝门部胆管分叉部位PBP平面结构显示胆管扩张，胆管壁明显增厚，壁内微血管尖细，排列紊乱，内层微血管密度减低；PBP立体构像显示空间结构紊乱，不规则，微血管细小，管壁不均匀增厚。与对照组相比，实验组肝门部PBP内层微血管总数明显减少（P〈0．01），肝门部PBP内层微动脉数也明显减少（P〈0．05）。实验组肝门部胆管壁呈慢性增生性炎症改变。结论 失去含氧量高的动脉血液供应时，PBP形态结构将会发生一系列改变，胆管壁组织也将发生相应的病理变化。     

围产儿与儿童胸腺的病理改变

The most outstanding pathological changes of perinatal babies and children, based on the review of the autopsy files in the 1st Affiliated Hospital of West China University of Medical Sciences, are lymphocytic depletion, and reticuloepithelial cell swelling and/or fusiform malformation in the cortex, while in the medulla apoptosis is more prominent. We suppose that these alterations are due to immaturity of cortical thymocytes, and in the diseased condition, they are easily affected by extraordinary factors, especially the influence of corticosterone inducing acute severe necrosis, so the number of lymphocytes are obviously diminished. But, in the medulla, as intact mature lymphocytes exist, physiological phenomenon such as apoptosis is rather prominent in it. While in the medulla, Hassall's corpuscles have various characteristic changes, such as cornification, calcification, fusion, cystic change and disintegration. Besides, we observed a new alteration in the thymus defined as vacuolization. All the above pathological changes reached the peak in the 28- day group; there after, they might become either worse or better according to the condition of the disease and growth of the body. However, these are still problems to be further studied separately.

家庭暴力及其应对策略

近几十年来，公众和社会逐渐认识到家庭暴力是一种主要的公共健康问题，它影响着不同种族、不同社会、不同经济背景中的个体。目前家庭暴力依然是当今社会中的一大问题。结束家庭暴力要求全体社会的共同关注，包括卫生保障部门、执法部门、社会服务系统联合起来应对家庭暴力。     

我校资产管理网络化的初步实现

1背景随着国家对教育投入逐年增加,特别是近年来重大科研项目如211工程、985项目等大批经费用于设备添置,学校固定资产急剧膨胀。同时高校规模不断拓展,综合性高校拥有2个以上校区的情况非常普遍。在这种情况下沿用旧的单机管理模式,
