耐力训练过程中大鼠体内糖储备及胰岛激素变化与黄芪、生脉穴位注射的干预效应

目的:穴位注射疗法在临床应用较多,但在运动医学领域研究不多。观察穴位注射黄芪、生脉对耐力训练大鼠糖储备和运动能力的影响。方法:实验于2004-07在陕西师范大学完成。①实验分组:健康雄性SD大鼠32只,体质量180～220g,随机抽签法分为安静对照组、训练对照组、生理盐水组、药物注射组,每组8只。②实验方法:建立穴位注射黄芪、生脉大鼠的耐力跑台训练实验模型,安静对照组安静笼饲养。训练对照组、生理盐水组、药物注射组先于动物跑台上进行5周适应性训练,之后跑速每周递增,5d/周,共5周;然后进行2周的大强度耐力训练,30min/d,7d/周,共2周。训练对照组、生理盐水组、药物注射组第8周第1天以速度为35m/min运动至力竭。③实验评估:7周后取材测定肝糖原、肌糖原、血清胰岛素、胰高血糖素的变化。实验中对动物处置符合动物伦理学标准。结果:纳入大鼠32只,均进入结果分析。①通过大强度耐力训练,药物注射组与其他3组相比,肝糖原含量均升高(P<0.05);训练对照组肌糖原比安静对照组降低(P<0.05),生理盐水组与训练对照组相比则显著性升高(P<0.01)。②训练对照组胰岛素比安静对照组明显降低(P<0.01);生理盐水组及药物注射组都能抑制这种降低的趋势(P<0.01);药物注射组胰高血糖素较安静对照组、训练对照组要高,且有显著性差异(P<0.01)。结论:穴位注射黄芪、生脉使大强度耐力训练大鼠体内糖储备显著增加,同时可以提高胰岛激素水平,从而提高了大鼠的运动能力。     

富氢水对大鼠超比例随意皮瓣存活的影响

目的观察富氢水对大鼠超比例随意皮瓣微循环血流量及存活面积的影响。方法将2~3个月的SD大鼠72只随机分为对照组、富氢水组,每组36只。术前2周,富氢水组自由饮用富氢盐水,对照组自由饮用生理盐水。在大鼠背部制作蒂在尾部的9.0 cm×1.5 cm矩形随意皮瓣。激光多普勒血流监测仪检测皮瓣微循环血流量,HE染色,光镜下观察皮瓣组织学改变。术后1、3、7 d计算皮瓣存活率。结果富氢水组近蒂部、中部血流量与对照组比较明显升高,差异有统计学意义(P0.05);术后7 d,富氢水组皮瓣存活率明显高于对照组,差异有统计学意义(P0.05)。结论饮用富氢水对超比例随意皮瓣的缺血再灌注损伤具有明显的保护作用,可改善超比例皮瓣微循环血流量,从而提高皮瓣的存活率。

耐力运动增加糖尿病大鼠血清瘦素水平的研究

目的：探讨耐力运动与体重调节密切相关的血清瘦素水平的关系，观察耐力运动对正常大鼠和糖尿病大鼠体重、血糖、血清胰岛素和血清瘦素的影响。方法：将实验动物分成4组，分别为正常对照组、正常耐力运动组、糖尿病组、糖尿病耐力运动组。所有运动组按Ploug方法进行游泳训练。结果：正常耐力运动组大鼠8周游泳训练后的血清瘦素浓度较运动前显著降低。糖尿病耐力运动组大鼠8周游泳训练后的血糖浓度较运动前降低35％，血清胰岛素浓度较运动前升高38％，血清瘦素浓度较运动前升高40％，8周期间每周体重增加数明显回升。结论：正常生理状态耐力运动能降低血清瘦素水平，这是机体为维持自身体重稳定和能量平衡的一种适应性反应；而在STZ糖尿病状态下，瘦素似乎与胰岛素关系更密切，耐力运动在降低血糖、改善机体对胰岛素敏感性的同时，似乎也改善了对瘦素的敏感性，耐力运动可增加糖尿病大鼠血清瘦素的水平。

Guns and Knives in New Mexico: Patterns of Penetrating Trauma, 1978–1993

Objective: To identify patterns of nonfatal and fatal penetrating trauma among children and adults in New Mexico using ED and medical examiner data.
Methods: The authors retrospectively sampled in 5-year intervals all victims of penetrating trauma who presented to either the state Level-1 trauma center or the state medical examiner from a 16-year period (1978–1993). Rates of nonfatal and fatal firearm and stabbing injury were compared for children and adults.
Results: Rates of nonfatal injury were similar (firearm, 34.3 per 100,000 person-years; stabbing, 35.1). However, rates of fatal injury were significantly different (firearm, 21.9; stabbing, 2.7; relative risk: 8.2; 95% confidence interval: 5.4, 12.5). From 1978 to 1993, nonfatal injury rates increased for children (p = 0.0043) and adults (p < 0.0001), while fatal penetrating injury remained constant. The increase in nonfatal injury in children resulted from increased firearm injury rates. In adults, both stabbing and firearm nonfatal injury rates increased.
Conclusions: Nonfatal injury data suggest that nonfatal violence has increased; fatal injury data suggest that violent death rates have remained constant. Injury patterns vary by age, mechanism of trauma, and data source. These results suggest that ED and medical examiner data differ and that both are needed to guide injury prevention programs.     

Prise en charge des entorses externes de cheville : étude clinique préliminaire sur l’efficacité du dispositif Myolux™

Ankle sprains are the most common injury of the musculoskeletal system and are associated with significant societal and economic impacts. It has been proven that classical therapeutic strategies may not be effective in preventing recurrent injuries: the recurrence rates reported in the literature can reach 73%. In order to provide an effective rehabilitation solution, a destabilizing orthosis was developed. This device is equipped with a mechanical articulator reproducing the subtalar mechanics and placed under the heel. In this paper, we present the main results of a preliminary clinical study conducted between 2004 and 2007. All subjects included in this study were treated with the abovementioned orthosis during 10 rehabilitation sessions of 30 minutes each. Data show a relatively low recurrence rate of 12% for the overall population. Moreover, it's of primary importance to note that this satisfactory ratio is largely reduced (3% of recurrence rate) for the 29 patients who performed one training session per month after the 10th initial rehabilitation sessions. Hence, the destabilizing orthosis appears to be an effective solution to prevent recurrent ankle sprains. However, joint protection requires long-term and regular training sessions. This result has motivated the development of a similar device allowing patients to perform training sessions at home. Finally, data obtained in this study are promising awaiting the final results of the comparative, multicentric and independent clinical trials currently managed by the Hospices Civils de Lyon.     

Clinical Trial Updates and Hotline Sessions presented at the European Society of Cardiology Congress 2007

This article provides information and commentaries on trials which were presented at the Hotline and Clinical Trial Update Sessions at the European Society of Cardiology Congress 2007 in Vienna. The key presentations were performed by leading experts in the field with relevant positions in the trials or registries. It is important to note that unpublished reports should be considered as preliminary data, as the analysis may change in the final publications. The comprehensive summaries have been generated from the oral presentation and the webcasts of the European Society of Cardiology and should provide the readers with the most comprehensive information of relevant publications.     

Balance and Boundaries in Grief Counseling: An Intervention Framework for Volunteer Training

Volunteers or paraprofessional counselors are commonly used to provide supportive care to the bereaved. These counselors generally are trained in basic listening skills, providing a generic, nonspecific approach to intervention that remains to be proven effective. The present paper outlines a framework that provides paraprofessionals with a broader model for intervention with the bereaved. Attention to boundaries as a helper and balance in the grief recovery are central to the model. Interventions are described that provide the paraprofessional counselor with more options for tailoring their counseling strategy to the individual. These include techniques that are presumed to be more specific to the enhancement of grief recovery.     

A new method for the simultaneous analysis of unmodified and modified urinary nucleosides and nucleobases by high performance liquid chromatography

Details are given of a new, rapid and simple pre-fractionation method and an isocratic high performance liquid chromatography system suitable for parallel analysis of nucleosides and nucleobases from urine and other biological fluids. The quantitative recovery and excellent reproducibility of the method is demonstrated by analysis of representative standard RNA catabolites. The advantage of this new method for application to biological samples is discussed.     

Adsorption of Charged Non-albumin Bound Drugs by Amorphous Silica

We investigated the in vitro drug adsorption of PQ 10150 sodium silicate gel (AIS, Santa Clara, CA) with particle size of 230 um and surface area of 400 nr/g. We observed 99% to 88% adsorption of gentamicin; a mean 91 % of disopyramide; a mean 89% of quinidine at low concentration, falling to 75% at higher concentration. Insulin was 88% adsorbed at low concentrations but less so (65%) at higher concentrations. We observed a mean 83 % adsorption of procainamide, a mean 84% of N-acetyl procainamide, 74% oflidocaine, 73% of amitriptyline; and 44% of desipramine. We found an average 14% reduction of total digoxin concentration when serum containing digoxin (2 to 33 ng/mL) was exposed to sodium silicate, while the reduction in free digoxin concentration was 16%. Five percent ethosuximide was also removed. The adsorption of theophylline, phenobarbital, acetaminophen, phenytoin, ethylene glycol, methotrexate, salicylate, thiocyanate and diazepam was minimal and not significant. We conclude that significant amounts of charged, non-albumin bound drugs can be removed by PQ 10150 sodium silicate gel.
