稳心颗粒对心房颤动患者射频消融术后早期复发的影响

目的 观察稳心颗粒对心房颤动患者射频消融术后早期复发的影响。 方法 入选拟行房颤射频消融术的住院患者,其中试药组 35例（稳心颗粒组）和对照组 36例。患者射频消融术后常规给予胺碘酮和华法林,试药组加用稳心颗粒。观察两者入院时及术后3个月血清氨基末端B型钠尿肽原（NT-proBNP）水平、入院时及术后3个月左房内径大小及早期复发情况。结果 试药组早期复发率为9%,对照组早期复发率为31%,两组比较差别有显著意义（P<0.05）;术后3个月两组NT-proBNP水平及左房内径呈下降趋势,且试药组明显低于对照组(P<0.05)。结论 稳心颗粒能够减少房颤射频术后早期复发,降低NT-proBNP水平及缩小左房内径。     

检验教学必须与临床实践相结合

探讨中等卫校生化检验教学人员必须与临床实践相结合，才能提高检验教学质量、丰富教学内容、增强动手操作能力、弥补学校仪器设备的不足。使学生学有所用，学有所成。     

希氏束起搏的研究进展

生理性起搏是心脏起搏与电生理领域的研究热点,希氏束起搏因为最大限度地保留生理性心室激动顺序,被认为是最具生理性的起搏模式。该文介绍希氏束起搏的定义、电生理特点与临床研究进展。     

浅谈动物实验工作人员的安全和防护

中等卫校医学教育的突出特点之一是它的实践性，重视理论与实践相结合。中等卫校培养出的学生不仅要具备扎实的专业理论基础知识，还必须有较强的实践能力。实践性教学是提高学生实践能力，培养实用型人才的重要手段，而动物实验则是进行实践教学的重要环节。从事动物实验的工作人员，由于经常接触动物，他们存在着很多安全隐患，如动物房舍和关养动物的笼具、动物实验仪器设备、水电设施等方面，还有机械性、理化性、生物性以及实验人员操作不当引起的隐患，必须加以重视，平时要做好必要的保健和防护措施。本人根据自己的工作经验总结体会如下，与同行们探讨。     

警惕日常饮食中的18种致癌因素

癌症的发生与饮食有密切的关系。有研究（《科学》杂志2007年1月）表明，30％的癌症死亡是由饮食不当造成的。饮食中动物脂肪（以不饱和脂肪为主）过多、蔬菜和水果过少，烹饪方法不科学、进食方式不合理等都是致癌的主要因素。     

The diameter of coronary artery is enlarged in patients with dilated cardiomyopathy

Background Dilated cardiomyopathy(DCM) is a primary cardiomyopathy characterized by the enlargement of left ventricle or biventricular and left ventricular systolic dysfunction, without any obvious stenosis of coronary arteries. However, it remains unclear that whether the diameter of coronary artery is different from those of normal population, because few studies directly assessed the diameter of the coronary artery in patients with DCM. The study aimed to evaluate the diameter of coronary arteries in DCM patients and its influence on prognosis for DCM patients. Methods Fifty-seven DCM patients and fifty-nine patients presenting with atypical chest pain and normal coronary angiography were enrolled in the study. A coronary angiography image analysis system was used to measure the diameters at 5 mm from the opening of the left main coronary artery(LM), left anterior descending(LAD) and left circumflex coronary(LCX) arteries, and the right coronary artery(RCA) of both groups. Follow-up study through telephone over a period of 2 years was performed. Spearman rank correlation and logistic regression were used to evaluate the correlations of the diameter of coronary arteries with the risk of nonfatal heart failure event. Results Diameters of the LM, LAD, LCX, and RCA in DCM group were significantly larger than those of the control group(P 0.001). During a follow-up of 2 years, the nonfatal heart failure event occurred in 9 patients of DCM group, but not in control group. Spearman rank correlation analysis showed diameters of the LM, LAD, and LCX were correlated with the risk of nonfatal heart failure event, respectively(P 0.05). While the diameter of RCA showed no correlation with the risk of nonfatal heart failure event(P =0.583). Whereas logistic regression analysis showed there were no correlation between diameters of the LM,LAD, LCX, and RCA and the risk of nonfatal heart failure event(P 0.05). Conclusions The coronary arteries of DCM patients show a larger diameter without any obvious stenosis, which may not correlate with the risk of heart failure event.
