推拿在高校体育实践中的运用状况

推拿在我国各大高校中已有初期运用,其在高校的体育实践课和运动健康方面的保障均有成功案例,这对高校体育实践产生了一定影响。本文通过对推拿在高校体育实践中运用状况的分析,从不同角度阐述这些应用的影响及作用,以及推拿对于高校体育发展的意义。     

还原型谷胱甘肽联合甘草酸二铵对腹部开放伤后海水浸泡犬肝功能损伤的治疗作用

Objective To investigate effect of reduced glutathione and diammonium glycyrrhizinate on the treatment of hepatic damage in experimental dogs following open abdominal injuries coupled with seawater immersion. Methods Twenty-four dogs with open abdominal injuries were randomly divided into 3 groups: the control group (given with simple observation after 1.5 h seawater immersion); the routine treatment group (given routine care and fluid transfusion after 1.5 h seawater immersion) ; the hepatic treatment group (given routine are, fluid transfusion and hepatic treatment as well, after 1.5 h seawater immersion). Each group consisted of 8 dogs. Blood samples were taken at different time points to measure total bilirubin (TB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), prothromin time (PT), endotoxin, tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), and pathological examination was also made at the same time. Results For the control group, contents of TB, ALT, AST and LDH increased significantly and survival time was less than 24 hours. Contents of TB, ALT, AST and LDH of the routine treatment group also increased significantly, but survival time of all the experimental animals was mere than 24 hours. Reduced glutathione and diammonium glycyrrhizinate could reduce the extent of lesion quite significantly 12～24 hours following open abdominal injuries. Conclusions Reduced glutathione and diammonium glycyrrhizinate seemed to have good effects on the treatment and prevention against hepatic damage induced by trauma coupled with seawater immersion. It could be used as a primary means for the treatment of such kind of hepatic damage.     

不同低浓度罗哌卡因低位硬膜外镇痛对运动神经阻滞的临床观察

目的 观察不同低浓度罗哌卡因（ropivacaine,Rop）低位硬膜外镇痛对运动神经的阻滞作用。探讨罗哌卡因低位硬膜外镇痛的最佳药物浓度。方法 随机选择我院67例下腹部择期手术患者，术后随机分为5个治疗组（A、B、C、D、E）和一个对照组（F），3h后硬膜外腔用药。前5组使用不同浓度罗哌卡因（A：0.1%;B:0.15%;C:0.2%;D:0.25%;E:0.3%），F组使用0.9%生理盐水。注药前后20分钟分别观察、记录以下项目：1.视觉模拟评分（Visual analogue scale,VAS）；2.阻滞区运动神经反射；3. 下肢指令运动。结果 不同低浓度罗哌卡因均有程度不同的术后镇痛作用。对运动神经的阻滞作用A、B、C三组与对照组无显著性差异（P＞0.05），而D、E两组有显著性差异（P＜0.05）。结论 选择浓度为0.2%的罗哌卡因低位硬膜外镇痛既可以有效地发挥术后镇痛作用，又最大程度地减少了对运动神经的阻滞作用，有利患者术后恢复。     

推拿治疗老年高血压及对动态血压负荷的影响

目的研究推拿治疗老年高血压及对动态血压负荷的影响。方法选择60例轻、中度高血压患者，随机分为推拿治疗组30例，药物对照组组30例。结果推拿治疗组总有效率为83．3％。药物对照组为86．7％；治疗组主要症状疗效前后对比有显著性差异（p〈0．05），治疗组治疗后动态血压负荷值明显降低，较治疗前差异有显著性（p〈0．01，p〈0．05）。结论推拿治疗老年高血压疗效显著，推拿可降低动态血压负荷。     

Abdominal aortic aneurysm repair and colonic infarction: a risk factor appraisal

OBJECTIVE: Colonic infarction is a recognized complication of abdominal aortic aneurysm (AAA) surgery. The clinical difficulty in establishing the diagnosis combined with the patient's poor physiological status is usually associated with a fatal outcome. We assessed our experience with this problem to identify a possible risk factor profile for these patients. METHOD: Patients records were identified from the operative logs, intensive care unit, Hospital Inpatient Enquiry system and vascular unit databases over a 6-year period. RESULTS: A total of 405 patients underwent AAA repair during this period; 140 as emergency ruptures. Nine patients were identified from the databases with known colonic infarction (2.2%). One was a woman. The mean age was 70 years. Seven patients had emergency ruptures (5%). Twenty independent risk factors were analysed using univariate and multivariate logistic regression models. Significant risk factors identified by using a multivariate analysis included the nature of the presenting patient, preoperative hypotension, prolonged cross-clamp time, intra-operative ischaemia and postoperative acidosis. Confirmatory diagnosis was made by colonoscopy in eight patients. One patient survived following the salvage surgery. The mean duration of survival was 10.5 days. The overall mortality was 89% of patients. CONCLUSION: In our unit infrarenal AAA repair has a 2.2% rate of colonic infarction. A definitive diagnosis is best made by colonoscopy. A risk factor profile for the development of colonic infarction may be constructed on the basis of specific clinical parameters. Earlier intervention on the basis of this profile may ultimately reduce the current excessive mortality.     

Effects of seawater immersion combined with open abdominal injury on the expression of NF-κB,and IκBαof small intestine in rats

Objective To observe effects of seawater immersion combined with open abdominal injury on the expression of NF-κB,and IκBαas well as the change pattern in rats. Methods Ninety-one Wistar rats were randomly divided into 3 groups: the control group (n =7), the open abdominal injury group(n =42) and open abdominal injury combined with 1-hour seawater immersion group ( n =42). The expression of NF-κB,andIκBαin small intestine tissues was measured by Western blot and statistical analyses were also made in the study. Results The expression of NF-κB,in the seawater immersion combined with open abdominal injury group increased significantly 3 hours after injury, when compared with that of the open abdominal injury group(P<0. 05), whereas the expression of NF-κB, of the pure injury group was slightly lower than that of the control group, but no statistical differences could be seen between them(P>0.05). The change pattern in the expression of IκBαwas quite the opposite to that of NF-κB. Conclusions NF-κB seemed to be rapidly and persistently involved in the whole inflammatory response to trauma induced by opened abdominal injury and seawater immersion, when a comparison was made with the pure open abdominal injury group. Injuries for the rats in the open abdominal injury combined with seawater immersion group were serious, and the feedback mechanism for NF-κB was not established for quite a long time.
