严重胸部钝性损伤后血浆PGI2、TXA2的变化及意义

目的探讨胸部钝性损伤后血浆PGI2、TXA2的变化规律，为临床救治胸部钝性损伤提供实验依据。方法利用BIM-Ⅱ型生物撞击机制备兔严重胸部钝性损伤模型；并用杏丁注射液干预血浆PGI2、TXA2的变化作为对照。分别于撞击前5min、撞击后5min、30min、2h、4h、8h、24h采颈总动脉血检测血栓素A2（TXA2）、前列环素（PGI2）的含量；于伤后24h摘取心脏作光镜检查，随机取2只兔心作电镜检查，观察心肌组织形态学改变。结果血浆PGI2浓度在伤后早期（伤后4小时）明显下降，而血浆TXA2浓度则明显升高。形态学检查心肌组织损伤较重。用杏丁注射液提高血浆PGI2浓度、降低TXA2浓度后心肌组织损伤则明显减轻。结论严重胸部钝性损伤后早期（4小时以前）血浆PGI2下降和TXA2升高可能会加重其合并的心肌挫伤。

兔心肌挫伤心功能障碍与心肌细胞内Ca2+和线粒体ATP酶的变化

目的：探讨心肌细胞内游离钙([Ca^2 ]i)和心肌ATP酶变化在心肌挫伤（MC）后心功能障碍发生机制中的意义。方法：随机选取兔36只，分为6组：正常对照、伤后2、4、8、12、24h，每组6只。经右颈总动脉插管至左心室测左室压力。采用BIM-II型生物撞击机致成MC模型。在上述时相点测定左室压力，并测定心肌细胞内[Ca^2 ]i和心肌匀浆组织及线粒体ATP酶活力。结果：心脏收缩/舒张功能受到损害，心肌细胞内[Ca^2 ]i升高，心肌匀浆组织及线粒体ATP酶下降，相关分析表明心功能障碍与心肌细胞内[Ca^2 ]i含量升高呈明显负相关，与ATP酶活性降低呈明显正相关。结论：MC后心脏功能下降，心肌细胞内[Ca^2 ]i含量升高和ATP酶活性下降可能是其原因之一。

心肌挫伤后心脏的病理生理变化

撞击伤是意外事故，特别是交通事故中的常见伤类。目前，年轻人死亡的最主要原因是交通事故伤，胸部撞击伤则是交通事故伤中引起死亡的第２位原因，仅次于颅脑创伤。在闭合性胸部创伤中，心脏创伤的发生率约为１０％～１６％。心脏创伤主要包括心肌挫伤、心脏破裂、心肌撕裂、心包损伤、冠状动脉损伤、心脏瓣膜损伤、心律紊乱及传导系统异常等，而胸部撞击所致的钝性心脏创伤则以心肌挫伤最为常见，不但发生于交通事故中，而且还发生于高处坠落、胸部受挤压及运动时［１］。心肌挫伤后常引起程度不等的心脏并发症，如低心排出量、严重心律失…

Survey and practice of reporting quality of randomized controlled clinical trials on traditional Chinese medicine

Evidence obtained from randomized controlled trials （RCTs） has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine （TCM） and results have shown that there is an urgent need for higher quality RCTs on TCM.     

TCM Treatment of Ankylosing Spondylitis by Tonifying the Kidney and Strengthening the Governor Vessel

Ankylosing spondylitis is a chronic and progressive disorder with inflammation mainly involving the central axis joints. It mainly affects the cervical spine and the lumbosacral area, with the pathogenesis closely related to the kidney and the Governor Vessel (GV). TCM holds that the syndrome is deficiency in origin and excess in superficiality, which is due to insufficiency of the kidney, deficiency of GV, and blocking of the channels with the invasion of exogenous evil, leading to poor circulation of qi and blood and malnutrition of the bones, muscles and joints. The TCM method of tonifying the kidney and strengthening GV to regulate circulation of qi and blood and check the arthralgia pain should be adopted, with the Kidney-Tonifying and GV Strengthening Decoction (益肾强督汤) prescribed.
