Prof. Ye Chuanhui''s Experience in Treating Nephritic Proteinuria

In the occurrence and development of glomerulonephritis, proteinuria is themain manifestation, which is easily recurrent but not easily got rid of in a short period of time. It may remain even after disappearance of the general symptoms. In some patients, there are no symptoms and signs at all in the initial stage, except proteinuria, the only distinct manifestation. Prof. Ye Chuanhui, from Chengdu University of Traditional Chinese Medicine, has accumulated rich experience for treating this disorder, which is introduced in the following.

大肠肿瘤组织中EB病毒的原位杂交检测

目的：探讨EB病毒感染与人大肠癌发生的关系。方法：用原位分子杂交法对130例人大肠癌标本中EB病毒小分子RNA片段进行检测。结果：130例标本中有6例（4.48％）癌组织呈阳性反应，其中4例为男性，4例有明显淋巴细胞浸润。结论：EB病毒感染可能与我国部分大肠腺癌的发生有关，肿瘤细胞间质中大量淋巴细胞浸润可能是EB病毒感染的重要病理学特征。     

No impact of repeated endoscopic screens on gastric cancer mortality in a prospectively followed Chinese population at high risk.

BACKGROUND: Gastric cancer (GC) is the leading cause of cancer deaths in China. Our study prospectively evaluated the impact of repeated endoscopic screens on GC mortality in a high-risk population in China. METHODS: Between 1989 and 1999, a population-based gastroscopic screening was conducted in 4,394 residents of Linqu County, China, a region with the highest rates of GC worldwide. Residents ages 35 to 64 years received initial gastroscopies with biopsies in 1989. Repeated endoscopies were performed in 1994 and 1999. Cancer occurrences and deaths were actively monitored throughout the entire period until July 2000. Mortality from GC was compared with expected values based on mortality rates obtained for Linqu in the 1990-1992 Chinese Cancer Mortality Survey. RESULTS: Between March 1989 and July 2000, 39,303 person-years were accumulated; 85 new GCs occurred, 29 (34.5%) were in early stage. Fifty-eight cases (68%) were identified at one of the screens. The number of observed deaths from GC (37) was close to the expected (36.8). The standardized mortality ratio was 1.01 (95% CI 0.72-1.37) for the entire cohort, 1.13 (95% CI 0.77-1.57) for males, and 0.65 (95% CI 0.26-1.32) for females. CONCLUSIONS: Despite high population coverage with repeated screens, no reduction in GC mortality was observed in this high-risk population in China.     

蒙药制剂中毒性药物的应用分析

蒙医学在长期的临床实践中总结和探索出较为科学的毒性药物炮制、制剂配伍和应用方法，使毒性药物在临床得到极为广泛的应用。特别是蒙药一般选用生药、多复方、用量小、服用方法简便、起效迅速，其作用较等量中药制剂强而有力，其中重要原因之一就是蒙医学擅长使用毒性药物及峻烈药材，以毒攻毒，多有奇效。成方中含有毒药物的方剂比率较高，据《蒙医成方选》一书记载：解痉镇痛药全部8个配方，白喉肿毒治疗药配方24个中有20个，     

竹林区村庄白纹伊蚊孳生特点的调查

白纹伊蚊在竹林里孳生的阳性比为75.4%;而在竹林包围的居民区阳性比为15.3%。白纹伊蚊在居民区孳生密度布雷图指数为19.4,容器指数为6.2%。居民区孳生蚊虫的主要场所是泡菜坛,泡菜坛主要孳生蚊种是骚扰阿蚊,阳性比为73.7%,其次是淡色库蚊为20.2%,贪食库蚊为14.0%,白纹伊蚊最低,为9.1%。     

梅毒诊治中存在问题及对策

目的：阐述对梅毒诊治中存在的问题并提出对策。方法：对本院检出的72例梅毒病例进行临床分析。结果：72例中44％(39／72)的患者未进行正规治疗及定期复查，51．3％。(16／39)的患者确诊后和治疗前未做滴度测定。结论：对可疑病人常规行梅毒血清学试验，早期诊断，正规足量治疗，治疗前行滴度测定，定期复查是诊治的关键。

The N-methyl-D-aspartate antagonist, MK-801, fails to protect against neuronal damage caused by transient, severe forebrain ischemia in adult rats

The neuroprotective effects of dizocilipine maleate (MK-801), a noncompetitive antagonist of the N-methyl-D-aspartate (NMDA) receptor/channel, were tested in the 4-vessel occlusion rat model of forebrain ischemia. Adult Wistar rats, treated intraperitoneally with MK-801 or saline using several different treatment paradigms were subjected to 5 (n = 208) or 15 (n = 62) min of severe, transient forebrain ischemia. In saline-treated animals, 15 min of ischemia (n = 13) produced extensive and consistent loss of pyramidal neurons in the CA1 zone of hippocampus. The degree and distribution of cell loss were not reduced by single dose preischemic administration of MK-801 at 1 (n = 7), 2.5 (n = 4), or 5 mg/kg (n = 8). In other animals subjected to 15 min of forebrain ischemia, multiple doses of MK-801 (5, 2.5, and 2.5 mg/kg) given immediately and at approximately 8 and 20 hr after cerebral reperfusion (n = 5) did not alter CA1 injury compared to saline-treated controls (n = 5). Five minutes of forebrain ischemia in saline-treated animals, (n = 82) resulted in significantly fewer (p less than 0.001) dead CA1 pyramidal cells and a greater variance compared to animals subjected to 15 min of ischemia. Power analysis of the preliminary saline-treated animals subjected to 5 min of ischemia (n = 22) indicated that 60 animals per group were necessary to detect a 15% difference between MK-801 and vehicle-treated groups. Multidose treatment with MK-801 (1 mg/kg) given 1 hr prior to 5 min of ischemia (n = 60) and again at approximately 8 and 16 hr after recirculation failed to attenuate hippocampal injury.(ABSTRACT TRUNCATED AT 250 WORDS)     

肾小球微血管构型的扫描电子显微镜观察

应用微血管铸型扫描电镜技术研究8例成人肾脏的肾小球微血管构筑,结果发现:1.输入小动脉在肾小球血管极处分为2～5支小球内小叶微动脉。输入小动脉血管铸型的直径为126.35±20.5μm。2.肾小球是由小球内小叶微动脉、毛细血管、毛细血管网小叶间交通支和毛细血管输出根所构成的近似于球状体,小球内每个毛细血管网小叶均是一个独立的机能解剖学单位;3.299个肾小球均有一支输出小动脉,只有一个肾小球有两支输出小动脉。输出小动脉的血管铸型直径为91.35±11.7μm。4.输出小动脉起始处具有毛细血管前括约肌装置,此结构在调控肾小球内的微循环血流有着重要意义。
