Biomechanics of the golf swing in players with pathologic conditions of the forearm, wrist, and hand

Golf is an activity generally stressful to the hands and wrists and particularly can produce increasing symptoms in players with underlying problems such as hand and wrist arthritis or tendinitis. The purpose of this study was to quantitate wrist motion and club head/ball impact force in subjects with pathologic conditions of the hand, wrist, or forearm, within a laboratory environment. A regular straight-handled golf club was compared to a new BioCurve handle design that has a 19 degrees ulnar bend. We measured and compared the effect of the two grips on wrist motion, club head velocity, ball impact force, ball impact location, and isometric torsional strength in 20 subjects who had a variety of upper extremity disorders. This data was then compared to data collected in an identical fashion from golfers without such conditions. The results of our study show that there were no differences related to club handle design on impact force or impact location, club head velocity, or club head path and face angle. Wrist kinematic differences were minimal between handle designs. The differences that were significant (P less than 0.05) centered around the decreased ulnar deviation of the left hand that resulted when subjects used the BioCurve handle design, which also allowed greater resistance to torque than the straight grip club. In addition to collecting objective data, we asked subjects for their opinions of the two grips. As a whole, the normal group and the group with pathologic conditions noted more comfort, improved grip, and less shock transmission with the BioCurve handle.

老中青年急性心肌梗塞的临床特点及相关因素分析

急性心肌梗塞(acute myocardial infarction．AMI)是老年人常见的心血管疾病之一。但近年来，中青年AMI发病率有上升趋势，为了解各年龄段AMI的临床特点及其相关因素，现对某院近年来收住的AMI患者进行回顾性对比分析，现报告如下。     

Colposcopic assessment in microinvasive carcinoma of the cervix

Forty of the 87 patients with microinvasive carcinoma (MIC) of the uterine cervix who underwent surgery were diagnosed colposcopically and the results were compared with the cytological and histological diagnoses. The cytology showed preinvasive carcinoma in 20 (50.0%) patients and invasive carcinoma in 19 (47.5%) patients. A correct colposcopic diagnosis was made in nine (22.5%) patients as having microinvasive carcinoma, 21 (52.5%) patients preinvasive carcinoma and eight (20%) patients invasive carcinoma, to sum up accuracy rate as 32.1%. The abnormalities most commonly observed in colposcopy were mosaic, punctuation and white epithelium. In microinvasive carcinoma, the triad co-existed in 43% of the patients. Atypical vessels, characteristic of invasion, were found in only one third of the patients. Microinvasion, therefore, may not be evident on colposcopy alone. It is therefore necessary to apply cone biopsy, prior to definite therapy, to make an accurate assessment of the maximum depth and extent of the invasion prior to definitive therapy.     

益肾化浊注射液对慢性肾功能衰竭大鼠残余肾中细胞因子含量的影响

通过观察益肾化浊注射液对5／6肾切除大鼠残余肾中细胞因子含量的影响，益肾化浊注射液延缓慢性肾功能衰竭（CRF）模型大鼠肾功能减退的作用机理。结果显示：益肾化浊注射液可以降低5／6肾切在鼠血清肌,尿素氮（P＜0．01），下调肾组织中白细胞介素－1（IL－1）（P＜0．05），白细胞介素－8（IL－8）（P＜0．05）及肿瘤坏死因子（TNF）（P＜0．05）的总体水平，说明益肾化浊注射液可以通过下调5／6肾切除大鼠残余肾中相关细胞因子含量，抑制促炎细胞因子对肾脏的损害，从而延缓CRF的进展。     

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。
