两腔心及合并畸形的彩色多普勒超声心动图特征研究

Objective To probe into the color Doppler echocardiographic characteristics of bilocular heart (BH) and associated malformations. Methods Twenty patients of BH were examined with color Doppler echocardiography (CDE) and the characteristics were observed. All the CDE results were compared with angiocardiography and 14 were confirmed by operation. Results Nineteen cases were properly diagnosed based on the CDE characteristics,1 case were misdiagnosed as mitral atresia. CDE characteristics of BH were obvious:① Apical four-chamber view of two-dimensional echocardiography (2DE) showed total echo dropout in both the interatrial septum and the interventricular septum and disappearance of the intracardiac "cross". The common atrioventricular valve closed during systole and appeared as figure "8", named 2DE "8" sign. During diastole, the common atrioventricular valve opened to a common ventricle. ② Color Doppler flow imaging (CDFI) showed common intra-atrial flow signal entereda common ventricle through common atrioventricular valve during diastole in all patients and colorful reflux through common atrioventricular valve during systole in 15 cases. ③ Among the 20 eases, 16 of the common atria were situs solitus,4 were situs inversus; 10 of the common ventricles were type A,2 were type B and 8 were type C. According to the spatial relationship of the great arteries,there were 4 type Ⅰ ,7 type Ⅱ and 9 type Ⅲ.There were 18 pulmonary stenosis and 2 pulmonary hypertension. ④ In the presence of pulmonary stenosis, CDFI showed colorful shunt signals through pulmonary artery during systole. Conclusions BH and associated malformations have obvious echocardiographic characteristics. CDE has a specific value in diagnosing BH and associated malformations.

微生态制剂及其在临床上的应用

微生态制剂是根据微生态学的微生态平衡、微生态失调、微生态营养和微生态防治等理论,利用正常微生物群成员或其促进物质制成的能够调整机体微生态平衡的活的微生物制剂。又称为促生素、利生素、活菌制剂、益生素等,可分为益生菌、益生元、合生元三种类型。由于微生态制剂能够在数量或种类上补充肠道内所缺乏的正常微生物,可以调整或维持肠道内微生态平衡,增强免疫功能,促进营养物质的消化吸收,从而达到无病防病,有病治病的作用。因此,这一学科一经提出,便得到了广大生命科学工作者的足够重视,取得了迅速发展。     

人工流产术2000例临床分析

目的探讨两种人工流产术的效果。方法1800例早孕患者采用异丙酚全麻镇痛方法,200例采用传统扩宫法进行比较,分析结果。结果两组术中宫口松弛情况、术中副反应、人工流产综合征发生率差异显著（P〈0．05）。结论采用异丙酚全麻镇痛方法施术取得良好效果,值得临床推广。
