Prof. Shan Zhaowei＇s Experience in Treating Atrophic Gastritis

Prof. Shan Zhaowei （ 单兆伟 ）, the author＇s teacher, has been engaged in TCM for more than 30 years, with profound knowledge in the treatment of diseases of the spleen and stomach, which are introduced in the following.     

The prevalence of LRRK2 Gly2385Arg variant in Chinese Han population with Parkinson's disease.

We conducted a case-control study to determine the prevalence of the LRRK2 Gly2385Arg variant in patients with Parkinson's disease in Han population in mainland China. Heterozygous LRRK2 Gly2385Arg variant was identified in 14 of 235 patients with Parkinson's disease (5.69%), but not in 214 unrelated healthy controls. Multivariate analysis indicated the frequency of Gly2385Arg variant in the female patients with early age at onset is higher than their male counterparts. The founder haplotype analysis showed the variant carriers shared the same founder. Clinically, the LRRK2 Gly2385Arg carriers presented with classical Parkinson's disease symptoms. Our study indicates that the LRRK2 Gly2385Arg variant is a potential ethnic-specific genetic risk factor of Parkinson's disease within Chinese Han ethnicity.

小剂量氯胺酮咪唑安定辅助硬膜外下剖腹产手术的临床探讨

目的对比观察剖腹产选用连续硬膜外麻醉时，辅助麻醉用药镇静及对牵拉反应抑制效果。方法选择行剖腹产手术产妇60例在硬膜外麻醉效果满意后，随机分两组各30例。Ⅰ组：哌替啶50mg，异丙嗪25mg单次静注。Ⅱ组：氯胺酮28．5mg，咪达唑仑1．42mg单次静注。分组记录用药前，1min，5min，15min及术毕产妇SpO2、RR、HR、MAP值；记录手术时间、术毕苏醒例数、术中恶心躁动例数；记录术毕产妇OAA／S评分；记录新生儿娩出时Apger评分。结果两组术中镇静、抑制牵拉反应效果均满意。两组RR、BP、HR、SpO2均平稳；术毕两组OAA／S评分均为4-5分；新生儿Apger评分均正常。结论两组方法效果确切，对产妇和新生儿安全。     

大豆皂甙和神经肽Y在下丘脑后核引起的心血管效应中的关系

微量注射大豆皂甙（Ｔｓ）到下丘脑后核（ＰＨＮ）能引起平均动脉压（ＭＡＰ）升高，心率加快，其效应与向ＰＨＮ内注入神经肽Ｙ（ＮＰＹ）相似。分别注入不能引起血压、心率发生明显变化的微量Ｔｓ、ＮＰＹ，如果合并注入ＰＨＮ则可引起血压、心率的显著变化，表明二者互有加强作用。Ａｔｒｏｐｉｎｅ可以对抗Ｔｓ、ＮＰＹ或Ｔｓ＋ＮＰＹ同时注入ＰＨＮ的升压效应，提示ＮＰＹ是通过激活脑内Ｍ受体而实现升压效应的，而Ｔｓ的心血管效应又可能是经过脑内ＮＰＹ介导和加强的。     

Clinical Observation on the Method of Supplementing Qi, Clearing away Heat and Promoting Blood Circulation for Treating 53 Cases of Gastritis Related to Pyrolic Helicobacterium

According to the clinical experience of professor Shan Zhaowei (单兆伟), the author has successfully developed Qingyou Yangwei Capsule (清幽养胃胶囊capsules for eliminating pyrolic Helicobacterium and nourishing the stomach) for treating the gastritis. Clinical research has shown that the capsule has a good curative effect on chronic gastritis related to pyrolic Helicobacterium. Among the 53 cases in the treatment group, clinical observation showed cure in 6 cases, obvious effect in 18 cases, effect in 24 cases, no effect on 5 cases, with a total effective rate of 90.5%. Of the 50 cases in the control group, cure was found in 5 cases, obvious effect in 13 cases, effect in 20 cases, no effect in 12 cases, the total effective rate being 76%. The total effective rate in the treatment group was higher than that in the control group. The rate of eliminating pyrolic Helicobacterium in the treatment group was 66.04%, similar to that in the control group. In a follow-up visit 6 months later, the recurrence rate in the treatment group was 13.33%, obviously lower than that of 41.66% in the control group.     

移植肾血管痉挛原因探讨

通过对临床37例肾移植的观察，发现术中移植肾开放血流后肾血管痉挛现象与当时血压明显相关。收缩压大于24kPa者，移植肾血管痉挛率为53．33％，收缩压低于24kPa者，移植肾血管痉挛率为9．09％。两组有显著性差异（P＜0．01）．发生血管痉挛的肾脏排尿时间较未痉挛者明显延长，分别为23±6．35min．3．8±0．86min，两组差异极显著（P＜0．01）．从而认为肾移植术中提升血压应适度，并针对移植肾血管痉挛的原因进行了讨论。     

波纹龙虱捕食蚊幼功能反应研究

作者于1991年7～9月,对波纹龙虱捕食淡色库蚊幼虫功能反应进行了研究。结果表明。在实验室条件下,波纹龙虱的捕食量随着蚊幼密度的增加而增大,其曲线符合Holling Ⅱ型功能反应,即其捕食量与猎物密度呈负加速曲线型。并根据Holling圆盘方程,建立了波纹龙虱捕食功能反应数学模型。波纹龙虱的寻找效应随着猜物密度的增加而降低。     

氟罗沙星的体内外试验相关性研究

本文研究了新型喹诺酮类药物氟罗沙星体外溶出与体内吸收之间的相关性。实验表明，本品口服吸收在血清中达峰时间较快，作用持久，消除半衰期为９．６０ｈｒ。在人工胃液中溶出速率较快，在血清达峰之前，体内吸收与体外溶出量之间呈现良好的相关性。     

Nasal septum lesions caused by chromium exposure among chromium electroplating workers

A chromium electroplating worker, suffering from epistaxis during work, was found to have nasal septum perforation. To determine the etiology and prevalence of nasal septum lesions, we conducted a survey of seven chromium electroplating factories and examined 79 workers. Forty workers from three aluminum electroplating factories were also enrolled as the reference group. Subjects were thoroughly examined by an otolaryngologist and each of them provided a blood and urine sample. A questionnaire interview regarding symptoms of the upper respiratory tract, past medical history, life style, and work history was also conducted. Air chromium concentrations were measured by taking area samples for 4–6 hours. Based on field observation and chromium measurements, we divided chromium electroplating into three different exposure zones: workers directly dealing with electroplating tanks (n = 31), other process workers (n = 29), and office workers and drivers (n = 19). Among the 79 chromium electroplating workers, there were 16 cases of nasal septum perforation, and 42 with either scar formation or ulceration; 10 chromium electroplating workers developed skin ulcers after performing chrome plating. No workers from aluminum electroplating factories had any nasal septum or skin abnormalities. There was a consistent trend between the degree of chromium exposure and the signs and symptoms related to the nose, throat, and skin. Immediate improvement of occupational hygiene is warranted.
