Chronic Kidney Isograft and Allograft Rejection

In this study antigen-independent factor in the pathogenesis of chronic rejection of organ transplants was examined.Kidney isografts and allografts were transplanted orthotopically into bilaterally nephroectomized rat recipients and studied functionaaly,morphologically and immunohistologically,at serial intervals up to 52 weeks after transplantation.Allograft recipients developed progressive proteinuria after 12 weeks,with gradual renal failure ultimately leading to death.At the same time,morphological changes,including progressive arteriosclerosis and glomerulosclerosis ,tubular atrophy and interstitial fibrosis,developed.Immunohistologically,macrophages infiltrated glomeruli during this period and cytokines became unregulated.Our results showed that antigen-independent functional and morphological changes occurred in long-tern kidney isografts and mimicked those appearing much earlier in allografts that reject chronically.Initial injury and extent of functioning renal mass is suggested to be important factor for such late changes.     

健康教育在糖尿病病人中的应用

目的：通过对患者在住院过程中的系统教育，使患者了解自己疾病的知识，提高患者对糖尿病的认知水平和自我管理能力，养成良好的健康行为和生活方式，从而提高生活质量。方法：采用集体、个体、自学等形式进行教育。结果：通过培养，患者掌握了一些基本的操作技能，明显缩短了住院日，同时激发了护士与患者学习专业知识的热情，减少或延缓了并发症的发生。结论：①健康教育是一个护患双边活动过程。②通过教育，可不断提高护士的自身修养和专业知识水平。③健康教育是糖尿病患者学习糖尿病知识，提高自我护理能力的有效途径。     

利多卡因宫旁阻滞麻醉在人工流产中的应用

人工流产手术虽然时间短,一般不需麻醉,但毕竟是手术操作,也给受术者带来一定的痛苦[1]。患者由此产生恐惧心理,甚至发生人流综和症等一系列并发症。我院门诊针对这种情况在人流手术中采用利多卡因宫旁阻滞麻醉,取得良好效果,现报道如下。1资料与方法1.1一般资料2005年3月至200

头胸导联、常规导联心电图诊断冠心病的比较——与冠脉造影结果对照

同步记录72例拟诊冠心病患者头胸导联(HC)及常规导联(wilson)心电图(ECG),并与冠脉造影结果对照。结果:HC与Wilson导联ECG对冠心病诊断的敏感性分别为88.9％与81.5％,特异性33.3％与27.8％,准确性75％与68.1％;二组导联对比无明显差异(P>0.05);对右心室梗塞、缺血及左心室后壁缺血.HC导联的敏感性(91.7％)及准确性(94.4％)均显著高于Wilson导联(12.5％、70.8％,P<0.01),并与冠状动脉病变程度呈高度正相关。HC导联优于Wilson导联。     

Mid-p confidence intervals for the poisson expectation

Conventionally a confidence interval (CI) for the standardized mortality ratio is set using the conservative CI for a Poisson expectation, μ. Employing the mid-P argument we present alternative CIs that are shorter than the conventional ones. The mid-P intervals do not guarantee the nominal confidence level, but the true coverage probability is only lower than the nominal level for a few short ranges of μ. The implications for mid-P confidence intervals of various proposed definitions of two-sided tests for discrete data are discussed.     

Application of enzyme linked immuno-electrophoresis for the diagnosis of tuberculosis]

The technique of Enzyme linked immuno-electrophoresis (ELIEP) was established to detect the specific antibody against tubercle bacilli. The results of 730 cases showed that the sensitivity of this method is 97.33%, and the specificity, 97.5%. Thus this method is more sensitive than the ELISA methods which had bean published. The manipulation of ELIEP is simple, convenient, and fast, reagent stable. This method may be used in diagnosis of tuberculosis with reliability and efficiency.     

喉癌患者染色体对致突变剂诱发畸变的敏感性研究

采用平阳霉素作为诱变剂，对２８例喉癌患者和２３例正常人做外周血淋巴细胞染色体对诱变剂敏感性研究，结果显示喉癌患者的染色体总畸变率、每细胞染色单体断裂率（ｂ／ｃ值）和细胞畸变率分别为１．９８％±０．０５％，０．５７％±０．３５％和４２．８％±１２％。正常人则分别为０．９４％±０．０４％，０．２８％±０．１２％和２７％±１２％。经统计学处理，喉癌患者组与正常人组的差异有高度显著性。并结合实验结果探讨了染色体对致突变剂的敏感性与患喉癌风险的关系。
