The modified outside-in suture: vertical repair of the anterior horn of the meniscus after decompression of a large meniscal cyst

This article describes a modified suture technique designed for the vertical repair of the anterior horn of the meniscus after arthroscopic decompression of a large meniscal cyst. This procedure comprises of three steps: first, the meniscus was pierced vertically using a suture hook and a No. 0 PDS suture. Second, both ends of the No. 0 PDS on the femoral and tibial surfaces of the meniscus were pulled to the outside of the joint capsule using a spinal needle preloaded with suture material. Finally, a skin incision was made adjacent to the suture materials, and both ends were tied. We recommend this technique not only for the vertical repair of the anterior horn of the meniscus after decompression of large meniscal cyst, but also to repair a longitudinal tear of the meniscus.

Ruptured distal anterior choroidal artery aneurysm.

Ruptured aneurysms of the distal anterior choroidal artery (AchA) are extremely rare and management is dictated by clinical presentation. This report describes a rare patient with a distal AchA aneurysm and subarachnoid and intraventricular haemorrhage. A 60-year-old woman presented with a sudden onset of severe headache and vomiting. No aneurysms could be found on initial angiograms. A repeat angiogram performed 10 days after admission demonstrated an aneurysm in a branch of the cisternal segment of the left AchA without a definite neck. Surrounding vessels showed multifocal stricture and dilatation. Microsurgical clipping was not performed because the patient died suddenly due to pulmonary failure. The aetiology of the aneurysm in this case and surgical strategy are discussed.     

中药膳食配合运动干预对肥胖性脂肪肝的影响

目的 探讨中药膳食配合运动干预对肥胖性脂肪肝的影响。方法 将68例脂肪肝患者随机分为对照组和观察组各34例。对照组常规给予低脂饮食和易善复、大黄庶虫丸等降酶保肝治疗；观察组按常规方法治疗外，采用中医辨证施食予以活血化淤、健脾利湿的中药膳食疗法配合运动干预．疗程均为1年。结果 治疗后观察组体重、甘油三酯、总胆固醇、谷丙转氨酶等显著低于对照组（均P〈0．01）。结论 中药膳食配合运动干预对肥胖性脂肪肝疗效显著。     

腺苷与异丙酚预处理对犬心肌缺血再灌注损伤的保护作用

目的探讨腺苷与异丙酚预处理对犬心肌缺血再灌注损伤的保护作用。方法 21只杂种犬,雌雄不拘,随机分为3组(n=7):缺血再灌注组(A组)、异丙酚预处理组(B组)、异丙酚与腺苷联合预处理组(C组)。A组冠状动脉的左前降支结扎60min后松开结扎,再灌注:120min;B组缺血前30min经静脉以5．6mg·kg-1·h-1速率持续泵注异丙酚30min;C组缺血前10min经主动脉根部一次性注入腺苷(10mmol·L-1,10ml),其余处理同B组。记录心脏血液动力学指标,并行节段性室壁运动评分(RWMS)。结果缺血即刻出现了缺血性心电图的变化。与基础值比较,A组缺血期及再灌注期 LVEDP升高,CO、SV、LVEF、CPP、RPP降低,再灌注期MAP降低,HR减慢,B、C组上述缺血再灌注诱导的血液动力学变化减弱,A组缺血期及再灌注期RWMS增加,但B、C组缺血期RWMS低于A组(P< 0．05或0．01)。结论异丙酚预处理对犬心肌缺血再灌注损伤有一定的保护作用,腺苷预处理并未增强其保护作用。     

Efficacy and safety of herbal medicines for idiopathic Parkinson's disease: a systematic review.

The objective of this study is to assess the efficacy and safety of herbal medicines (HMs), as a monotherapy or adjunct therapy, compared to placebo or conventional approaches in the treatment of idiopathic Parkinson's disease (PD). We conducted a systematic review of randomized controlled trials from both conventional and alternative medicine sources. Outcome measures were overall improvement, quality of life, reduction of levodopa dose, and adverse events. Nine studies were included, each testing a different HM. Six of the trials had limited internal validity due to major flaws in design, including the lack of proper randomization; insufficient blinding; unclear inclusive criteria in terms of diagnostic criteria, baseline staging, and duration of disease; lack of proper sample size calculation; and insufficient data analysis. Imbalances in gender and ethnicity among the patients in the included trials were observed. No major adverse events emerged, and no specific pattern was detected from the trials describing such data. In addition to major methodological defects, heterogeneity in (1) HM tested, (2) control treatment, and (3) outcome measure hindered in-depth data analysis and synthesis. Current evidence is insufficient to evaluate the efficacy and safety of various HMs. Further studies with improved trial design and reporting, with assessment on cost-effectiveness, quality of life, and qualitative data are warranted.     

东南欧国家旋毛虫病的流行现状

旋毛虫病在东南欧的巴尔干半岛及临近国家的流行现状各不相同,在保加利亚、塞尔维亚和黑山、罗马尼亚及克罗地亚,猪和人的旋毛虫感染率均较高;在波斯尼亚和黑塞哥维那则具有中度的旋毛虫感染率;在匈牙利已有多年未发现人体旋毛虫病,但近2年来已发现了散发的猪旋毛虫病。旋毛虫病在东南欧国家的再度肆虐,提示旋毛虫病能够突破食品安全体系和兽医检疫的薄弱环节,从而可导致地区性、全国性甚至国际性的旋毛虫病扩散。该文对旋毛虫病在东南欧国家的历史、分布、流行现状、感染来源、虫种及再度肆虐的原因等进行了综述。     

分瓶法测定果蝇吸入麻醉药半数麻醉有效浓度

β-胡萝卜素立体异构体对环磷酰胺处理小鼠免疫功能的比较研究

就β-胡萝卜素立体异构体对环磷酰胺处理小鼠的免疫功能影响进行了比较研究。结果显示β-胡萝卜素立体异构体对外磷酰胺造成的免疫功能低下具有不同程度的改善作用，提高胸腺和脾脏指数，增强脾脏细胞对刀豆素A（ConA）的反应性和NK活性，血清溶菌酶含量也有所增加。综合各项指标，9-顺式和全反式混合物的作用最明显，提示一定浓度的9-顺式对于提高β-胡萝卜素对机体的总体作用是有一定意义的。
