2013年南京市畜禽产品兽药残留调查

The clinical significance of Electrocardiogram and echocardiography in the diagnosis of acute pulmonary embolism

对2013年南京主要养殖区域内的畜禽产品进行兽药残留调查研究,以保障市民动物食品安全,促进畜禽养殖业的健康发展。本调查对南京市浦口区、溧水区、江宁区、六合区、高淳区等5个主要养殖区规模化养殖场2个不同养殖季节(夏季、秋季)的畜禽产品,包括猪肉、鸡肉、鸭肉、鸡蛋、牛奶随即抽取样品800份,运用高灵敏度兽药残留快速检测卡、ELISA试剂盒以及超高效液相色谱串联质谱方法 (UPLC-MS)对样品进行定性及定量检测。结果显示:800份畜禽样品均为阴性样品或远低于国家动物源性食品安全残留限量标准。抽检样品无兽药残留或兽药残留量远低于兽药残留限量标准,可安全食用。

Objective Application and clinical significance of ECG and echocardiography in the diagnosis of acute pulmonary embolism. Methods In recent years, our hospital on 68 patients with ECG in patients highly suspected acute pulmonary embolism transthoracic echocardiography and pulmonary angiography, And to analyze the results. Results ECGshowed：TypicalSⅠQⅢTⅢ27cases,V1,V2ECGTwaveinversionin48cases,V1-V3ECGT-wave inversion in 59 cases, V1, V2ST segment elevation 0.1mV 19 cases, lead V1, V2ST-segment elevation 0.1~0.2mV 12cases, IRBBB45 cases, Pulmonary P waves in 27 cases,4 cass of atrial fibrillation, Sinus tachycardia in 28 cases;Echocardiographyshowed： Pulmonaryarterybifurcation thrombosisin 2 cases, 30 casesoftypicalrightheartincreases and moderate pulmonary hypertension, 28 cases no obvious morphological changes of right heart but mild pulmonary hypertension; Pulmonary angiography showed： Bilateral pulmonary embolism in 38 cases, 11 cases of pulmonary embolismand right, rightpulmonaryembolismin 10 cases, 9 casesoftheleftpulmonaryembolism. Conclusions ECG diagnosis of acute pulmonary embolism and determine the severity and prognosis despite a limited role, but in close connection with the disease, and pulmonary angiography and echocardiography, comprehensive analysis,comprehensive judgment, to avoid misunderstanding ECG diagnosis of pulmonary embolism, the clinical diagnostic valuegreater.
