对妇科腹腔镜手术后恶心呕吐与麻醉方法的简述
随着工业制造的迅速发展,相关学科的融合为开展新技术和新方法奠定了尤为鉴定的基础,加之临床医生手术操作的娴熟,使得许多开放性手术被腔内手术取代,这大大增加了患者为手术选择的机会。腹腔手术作为近年来新发展起来的微创手术方法,在妇科外科手术中已得到十分广泛的应用。本文通过对相关临床资料进行分析,对妇科腹腔镜手术后恶心呕吐与麻醉方法的选择做一综述。

公共政策分析方法在卫生政策研究中的应用
公共政策学是一门综合性学科,本身没有很强的理论体系,其理论体系主要借鉴其它学科,包括政治学、经济学、社会学、管理学等.然而,公共政策学有一套独特的政策分析方法.在公共政策过程分析中,首先要把政策问题界定清楚.公共政策界定问题有两个条件,需要同时满足:第一,没有解决的办法,就不是问题;第二,只有有解,才是问题.公共政策和其它学科对问题思考的不同在于:其它学科一般强调对问题的存在性思考,而公共政策强调问题的行动性思考,如果无所行动,就不是问题.

医疗仪器的安全标准研究及医疗电气安全性测量的方法
随着现代电子技术和生物医学技术在医学实践中的不断应用和飞速发展,已经导致由多台设备组成的比较复杂的系统来取代单台医用电气设备,对患者进行诊断、治疗或监护.越来越多的这种系统是由原先不同专业领域制造使用的设备通过直接相连或间接相连而组成.为保护患者、操作者和环境的需要,国际电工委员会颁布了IEC60601-1-1(1992-06)和第一号修订件(1995-10).我国正在拟定GB9706.1标准的并列标准GB9706.1.1医用电气系统安全要求.

凉血化瘀法治疗重型肝炎立法依据探析
凉血化瘀法是温病治疗学中的重要治法,具有清热解毒、凉血散邪、化瘀通络等作用.我们通过对该法作用原理的深入研究,发现热瘀搏结是本法的主要运用指征[1,2],而热瘀搏结亦是重型肝炎关键的病理环节.近年来我们将凉血化瘀法运用于重型肝炎的治疗,取得了较为满意的疗效.经临床研究及动物实验,结果显示凉血化瘀方药在改善肝功能、提高存活率、减轻和修复肝细胞病理损害、抗肝细胞凋亡等方面有较好的效果.现就凉血化瘀法治疗重型肝炎的立法依据作一探讨分析,以期有助于中医药治疗重型肝炎研究的深入和发展.

清肺凉血化瘀法治疗急性发作期慢性支气管炎的临床研究
慢性支气管炎(下称慢支)属中医学咳嗽、痰饮、喘证等范畴,对其病机的认识,着眼于气分失调者众,而究其血分失常者鲜.所以,在治法上亦多注重调气,或宣散肺气,或肃降肺气等,多忽略调血之法.近年来,诸多学者对活血化瘀治疗慢支可提高疗效的认识渐趋肯定,但对凉血化瘀法治疗该病,在国内外文献中尚未见报道.数年来,我们在临床上应用清肺凉血化瘀法治疗急性期慢性支气管炎病人取得了较好疗效.为了阐明凉血化瘀法治疗慢支的有效性和科学性,笔者对其进行了临床研究,现将研究结果总结如下.

从循证医学展望中医药临床研究与实践
循证医学(Evidence-based Medicine,EBM)是以证据为基础的医学.它强调从系统研究中获取证据,并重视临床实践中个人经验与系统研究中所获得的科学证据相结合,是临床流行病学和现代信息学与临床医学结合的典范,在国际临床医学领域正日益受到重视和普遍运用.循证医学在我国方兴未艾,借鉴循证医学模式开展中医药临床研究与实践,对提高中医药临床科研水平、解决中医临床的重大诊疗问题、推动中医药现代化进程使其走向世界具有重要意义.本文试从循证医学角度探讨中医药临床研究与实践的现状和发展趋势.

中医药防治老年急性冠脉综合征的临床思路与方法
急性冠脉综合征(acute coronary syndrome,ACS)是由于冠状动脉粥样硬化斑块不稳定、斑块破裂或溃疡继发血栓形成、冠状动脉痉挛等因素导致冠状动脉管腔严重狭窄甚至完全闭塞,从而引起急性心肌缺血、损伤、坏死等的临床综合征.与较年轻患者比较,老年ACS患者多同时存在其他疾病,且冠脉病变更严重,或伴有左心室收缩或舒张功能受损,梗死心肌愈合能力低,对心肌缺血的耐受性差,因此病死率更高.

Thirty-six cases with hyperglycemia were treated with the method of promoting blood circulation and removing stasis in a course of 4 weeks. The treatment was significantly effective in correcting the abnormal viscosity of the blood by reducing the contents of total plasmic cholesterol (TC), triglyceride (TG) and apoprotein B (apoB), while the level of the apoprotein A (apoA) was elevated.

In this series of 65 cases of aplastic anemia, 26 cases were treated by the kidney-tonifying and mediating method, 19 cases by western drugs, and the remaining 20 cases only by tonifying the kidney as controls. The results showed that the kidney-tonifying and mediating method was significantly superior in the total effective rate to the method of western drugs and that of tonifying the kidney alone (P<0.01), and it was also superior in the improvement of symptoms, myelogram, and peripheral blood count to the other two methods.

Evacuating the bowels to remove internal heat is one of the major therapeutic principles in treating pediatric diseases. Since the children are incapable of controlling in take of milk or food, the accumulated foodstuffs in the body will impede the spleen and stomach in digestion and transportation. In addition, children are easy to be attacked by exopathogens, because their organs are tender and do not fully develop. Once an exopathogen gets into the interior, it will transform into heat. However, simple measures of eliminating the heat often fail in the treatment of some critical and emergent pediatric cases. We have treated such cases by the method of evacuating bowels to remove the internal heat with miracle effects and would like to share our experience with our colleagues. The following are some examples.

From January 1993 to December 1996, we treated 482 cases of cervical spondylopathy with a combined method of point-injection and needle-warming via moxibustion. Except for the cases of sympathetic nerve type and spinal cord type, the combined method was superior to traction therapy in the control group and reported as follows.Clinical DataThe Criteria of Diagnosis and Curative Effect in TCM issued by the State Administrative Bureau of TCM and Pharmacy in 1994 was adopted for the enrollment of patients of cervical spondylopathy and the pathological typing. Only the patients who had completed the treatment and with complete records were collected for analysis.

We have found that Batroxobin plays a protactive role in ischemic brain injury, which attracted us to investigate the effect of Batroxobin on apoptosis of neurons during cerebral ischemia and reperfusion. The apoptotic cells in ischemic rat brains at different reperfusion intervals were tested with method of TdT-mediated dUTP-DIG nick end labeling (TUNEL) and the effect of Batroxobin on the apoptosis of neurons was studied in left middle cerebral artery (LMCA) occlusion and reperfusion in rat models (n=18). The results showed that few scattered apoptosis cells were observed in right cerebral hemispheres after LMCA occlusion and reperfusion, and that a lot of apoptosis cells were found in left ischemic cortex and caudoputamen at 12h reperfusion, and they reached peak at 24h~48h reperfusion. However, in the rats pretreated with Batroxobin, the number of apoptosis cells in left cerebral cortex and caudoputamen reduced significantly and the neuronal damage was much milder at 24h reperfusion than that of saline-treated rats. The results indicate that administration of Batroxobin may reduce the apoptosis of neurons induced by cerebral ischemia and reperfusion and afford significant cerebroprotection in the model of focal cerebral ischemia and reperfusion.

度他雄胺PLGA微球的加速释放度试验研究
生物可降解注射微球是近三十年来药剂学的研究热点之一~[1],它能够显著延长给药间隔,大大提高患者用药的顺应性,同时维持低有效浓度,减少给药次数.聚乳酸-羟基乙酸共聚物(PLGA)由于其良好的生物相容性和可降解性,已被FDA正式批准为药用辅料.但缓释微球释放周期较长,给处方筛选和日常质量控制带来较多困难.因此,建立体外加速释放度试验方法,从而快速地评价微球的释药性质,缩短处方工艺优化的周期,有助于制剂工作者更加快速有效地进行处方分析.
