遏制轻型急性胰腺炎向重症转化的非手术 治疗策略

目的 ：探讨遏制急性胰腺炎向重症转化的非手术治疗策略。方法 ：将4年间收治的286例轻型急性胰腺炎分为对照组和治疗观察组。对照组采取常规非手术治疗措施;观察组加用改善胰腺微循环，防治细胞钙超载和抑制胰酶的治疗方法。结果 ：对照组144轻型有20例转化为重症胰腺炎，14例发生全身性并发症;观察组142例轻型有8例转化为重症，2例出现全身性并发症。观察组重症患者血C-反应蛋白和Balthazar CT严重度指数在治疗后各时点较对照组明显降低。结论 ：在常规治疗的基础上加用改善胰腺微循环，防治细胞钙超载和抑制胰酶的治疗措施可能有助于阻止轻型急性胰腺炎向重症化发展。     

设立门诊健康教育室需求的调查与分析

且的调查和分析门诊设立健康教育室的可能性与必要性，使门诊健康教育工作变得更规范．更系统。更科学、更有效，更经济。方法采用发放问卷的形式，随机对2004年1月-2006年1月在上海市桌三级综合性医院门诊就诊的200例病人进行不记名调查、统计和分析．结果病人在门诊就诊时普遍认为健康教育现状不够理想，而对健康教育需求较迫切，对于开设健康教育室十分受欢迎。结论门诊设立健康教育室可将现有的医院内存在的、分散的、不同形式的健康教育工作纳入一个集中、统一的部门，有利于提高门诊健康教育质量。     

Image-directed color Doppler ultrasonography in the evaluation of superficial solid tumors

Image-directed color Doppler ultrasonography (ICDUS) studies of 86 patients with superficial solid masses yielded significantly lower resistive index (RI) values in acute inflammatory lesions, but no significant difference between the maximum systolic flow velocities (S) of the patient groups with malignant, benign, and acute inflammatory lesions. When analyzed separately, the malignant soft-tissue tumor subgroup was shown to have significantly higher mean RI compared to that of the malignant node subgroup. We conclude that RI may be useful in the differentiation of acute inflammatory masses from other pathological entities. Malignant soft-tissue tumors, especially sarcomas, may have different Doppler features from those of carcinomatous tumors. © 1995 John Wiley & Sons, Inc.     

艾灸对30例健康人甲皱微循环及血液流变学的影响

目的：探讨艾灸对健康人甲皱微循环及血液流变学的影响。方法：选择健康学员及武警战士各30例，年龄20－22岁，应用江苏协达公司生产的XDM－1型微循环电脑检测仪及北京世帝科学仪器公司生产的LG－R－80血液粘度计，LG－B－190型红细胞变形／聚集测试仪。固定专人操作，分别于艾灸前及艾灸后，测试甲皱微循环及血液流变学各项指标的变化。结果：艾灸八邪及三阴交穴后，甲皱微循环各项指标均有明显变化，经统计学处理，红细胞聚集程度、血流速度、流态积分、管周积分均有显著性差异（P＜0．05），其余各项指标虽有不同程度的改变，但无统计学意义（P＞0．05）；血液流变学各项指标亦有明显变化，经统计学处理，全血低切相对粘度、全血低切还原粘度、红细胞刚性指数、红细胞聚集指数及血浆纤维蛋白原都有非常显著性差异（P＜0．01），全血高切相对粘度有显著性差异（P＜0．05），其余各项指标虽有不同程度的改变，但无统计学意义（P＞0．05）。结论：艾灸八邪及三阴交穴后可明显改善红细胞聚集程度，降低血液粘度，加快血流速度，降低外周血管阻力。     

深圳市南山区医疗机构消毒效果分析

目的:了解南山区各医院及个体诊所卫生消毒状况。方法:对2002~2003年间区属各医院及个体诊所消毒效果的监测结果进行统计分析。结果:2002年与2003年区镇医院消毒效果平均合格率分别为94.4%和97.1%,个体诊所平均合格率分别为87.6%和89.8%。结论:区(镇)医院消毒效果优于个体诊所,空气合格率普遍较低,卫生防疫机构要加大力度进行监督检测,同时加强对医务人员进行消毒知识培训。     

化疗药物对轴型皮瓣血运影响的组织学观察

目的探讨抗癌药物动脉灌注后对局部轴型皮瓣血运影响的组织学评价。方法在猪腹部的腹壁上动脉插管灌注抗癌药物,10d后在猪腹部形成以腹壁上血管为蒂的岛状皮瓣,通过对灌注区域轴型血管供养的岛状皮瓣的成活率、光镜、透射电镜及血管铸型透明标本的组织学观察,显示其血管结构及构筑的变化。结果抗癌药物用于局部动脉灌注后,使局部轴型血管支配的血管网有损伤的表现,岛状皮瓣远端的血运显著降低。结论抗癌药物经动脉灌注后可影响局部轴型皮瓣的血运,使皮瓣血供的安全范围缩小,为提高相关修复手术的成功率提供可靠的科学依据。     

Ultrasound Biomicroscopic Dark Room Provocative Test

Purpose : To compare the clinical application value of Ultrasound biomicrsocpic dark room provocative test with the traditional dark room test in screening primary angle closure glaucoma (PACG).Methods: 22 eyes with PACG in prodromal stage and 30 eyes with deep anterior chamber and wide angle of 15 normal persons were observed in this trail. All 52 eyes were performed traditional dark room provocative test and ultrasound biomicorosopic darkroom test respectively. With different positive diagnostic criteria, the sensitivity of the two methods were compared using chi-squared analysis.Results : After staying in the dark room for 2 hours, In case group, IOP in 10 of 22 eyes rose more than 1. 07kPa(1kPa = 7.5mmHg), in 12 eyes less than 1.07kPa or had no changes; appositional angle closure were found by Goldmann gonioscopy in 8 eyes : 3 eyes in two quadrants, 5 eyes in more than two quadrants; the appositional angle closure was found by UBM in 15 eyes; 3 eyes in one quadrants, 5 eyes in two quadrants, 7 eyes     

A study of blood supply of liver tumors using duplex Doppler ultrasound and color Doppler flow imaging

Summary With the use of duplex Doppler ultrasound and color Doppler flow imaging(CDFI), the characteristics of blood supply in neoplasma were studied in 51 cases of 60 liver tumors, and compared with the results of surgery, pathological examination and hepatic anerial angiography. The result showed that: 1. Doppler blood flow signals could be detected in all hepatic carcinomas, and in 10 cases of 18 hemangiomas, significant difference was observed (P<0.001); 2. Doppler blood flow spectra showed pulsatile pattern in 41 of 42 hepatic carcinomas, and in 6 of 10 hemangiomas (P<0.01); and 3. the peak flow velocity was obviously lower in hemangioma group than in hepatic carcinoma group (20.34±23.93 vs 64.74±30.18 cm,P<0.001). The characteristics of CDFI show that hemangiomas and hepatocellular carcinomas are different. It can, therefore, be concluded that the blood supply of hepatic carcinomas mainly comes from hepatic arterial system, and is of value in duplex Doppler ultrasound and CDFI.     

新型生物指示剂在紫外线消毒方面的应用

用一种可穿透紫外线的可溶性菌膜作为生物指示剂,检查紫外线的消毒效果。当紫外线剂量为12000μw·s/cm²时可杀灭99.9%以上金黄色葡萄球菌;50000μw·s/cm²可杀灭99.9%以上枯草杆菌芽孢。并且证明杀菌效力不完全取决于紫外线强度的高低,而照射剂量的大小在消毒效果中起关键作用。应用时根据不同消毒对象,调节照射时间,计算所需照射剂量,即可达到保证消毒质量的目的。应用新型生物指示剂检查紫外线消毒效果除简化操作程序外,还可以提高细菌回收的准确度及试验的重复性。
