白血病病人骨髓抑制期实施防感染措施时机的研究

目的 :研究白血病病人在化疗期间 ,不同时间实施预防感染护理的效果。方法 :对照组在化学疗法结束后给予预防感染的护理措施 ,实验组在化学疗法开始前 3～ 7d实施预防性护理措施。观察两组病人感染发生率。结果 :感染发生率实验组明显低于观察组。结论 :在化学疗法开始前实施预防性护理措施有助于降低感染发生率     

类保幼激素对三带喙库蚊幼期发育的影响

本文报告用亚致死剂量的 S—31183(类保幼激素)处理三带喙库蚊幼虫对其发育影响的研究,结果表明处理后蛹期死亡率明显高于幼虫期,并且与剂量大小有关。S—31183处理幼虫并不影响幼虫的发育时间,但可使幼虫化蛹时蜕皮受阻与羽化受到一定的抑制。

Laparoscopic Local Resection Based on Sentinel Node Evaluation for Early Gastric Cancer: A Preliminary Report

We previously reported that lymphatic mapping using isosulfan blue can be used to identify sentinel nodes (SNs). This study was undertaken to evaluate the feasibility of using the SN technique in treating early gastric cancer and to explore its usefulness for minimal invasive surgery. Twenty-three patients with early gastric cancer who underwent SN biopsy were retrospectively evaluated. Based on SN evaluation, individualized surgery was performed in five patients with T1N0M0 gastric cancer. When pathological examination of frozen sections revealed metastasis in SNs, we performed a standard D2 gastrectomy. Laparoscopic local resection was applied when the SN biopsy was negative. Our results showed that the success rate with SN biopsy in early gastric cancer was 100%, as were the accuracy, sensitivity, and specificity. All five patients with early gastric cancer had SNs negative for metastases both by frozen section and by postoperative pathology. Thus, all these patients underwent laparoscopic local resection without extended lymphadenectomy. We conclude that SN biopsy is a useful tool to individualize the operative procedure, and laparoscopic local resection can be safely performed using SN guidance in selected patients with early gastric cancer.     

危重型毛细支气管炎抢救体会：附31例分析

231例毛细支气管炎,危重型38例占16.4％,抢救成功31例占81.6％。本文讨论了危重型毛细支气管炎并多器官功能衰竭的发生与预后及平喘药物的合理选用。认为早期应用免疫疗法、迅速平喘、保护重要器官功能及合理治疗并存症是抢救成功的关键。     

应用电子计算机计算血液流变学的正常值及分析

为评价血流粘滞诸因素生理与病理的异常,对济南地区338例正常人血液流变学的各项指标进行了检测,统计了血液流变学各项指标的总平均及男女的平均值和正常范围,并计算了血液流变学各项指标间的相关系数。     

经腹及经阴道B超监测卵泡发育的评估

应用经腹及经阴道B超对68名不孕症妇女,139个月经周期进行卵泡发育及排卵监测。卵泡检出率TAUS为90.6％,TVUS为98.0％,显著高于前者,P<0.05。成熟卵泡特征影象(卵丘等)在TVUS显象率较高。TVUS监测卵泡发育更实用可靠。     

一种较好的RNA分离制备方法及其在人胚RNA提取中的应用

以钒基核苷酸复合物为核酸酶抑制剂,从人胚组织中制备总RNA,所得产品几乎不含DNA和蛋白质,经过分离Poly(A)~ mRNA,证明制品有合成cDNA的完整功能,方法比较简捷,适于大量制备以满足分离mRNA 之需,并讨论了此法的优缺点。
