【摘要】 本文从人群职业健康检查者中选择１６５８ 人，进行吸烟与非吸烟对血液中白细胞数影响的调查，结果发现吸烟与非吸烟者，已戒烟与从不吸烟者、每天吸烟量不同的各组间白细胞数有显著差异（Ｐ＜ ０ ．００１） ，戒烟１ 年内与戒烟１０ 年以上两组间白细胞变化明显（Ｐ＜ ０ ．０１） ，而戒烟１ ～１０ 年间白细胞数变化不显著（（Ｐ＞ ０ ．０５） 。确认吸烟能增加血液中白细胞数的事实，并认定随着每天吸烟支数的增加，血中白细胞数也增加。戒烟后血液中白细胞会急剧减少更多还原

【Abstract】 Objective To test the hypothesis that late recanalization of an occluded right coronary artery influences prognosis of arrhyhmias Methods Twelve patients with inferior myocardia infarction accompanied by arrhythmias have been selected Selective angiography was performed in eleven patients 24 hours after coronary artery occlusion Right coronary artery occluded in ten patients and coronary artery spasm took place severely in one patient, all of whom were performed delayed recanalization Results Of nine patients with AVB, eight cases showed no atrial ventricular node artery by CAG Seven patients showed atrial ventricular artery after PTCA and stent implantation Six patients regained normal heart rhythm One patent showed no atrial ventricular artery after the right coronary artery recanalized , whose Ⅲ°AVB permanent Two patients accompanied by sinus bradycardia regained normal rhythm after PTCA, of which one patient with inferior myocardial infarction was performed CAG a month later and showed that the second part of right coronary artery occluded; the other with old inferior myocardia infarction accompanied by frequent ventricular premature beats, short term ventricular tachycardia and Ⅱ°ⅠAVB at intervals, had little effect to medication RCA and LAD recanalized after PTCA Ventricular tachycardia and AVB did not take place by three month follow up Conclusion (1) Inferior myocardial infarction accompanied by AVB is almost due to the blood discon tinuation of atrialventricular node artery, which leads atrial ventricular conductive system to stunning; (2) As to RCA occlusion, especially accompanied by left coronary artery disease, Pay more attention to ventricular fibrilation when balloon withdrawn from occluded RCA Medication precedes balloon retratation if necessary; (3) As to myocardial infarction accompanied by arrhythmia, methods of treatment is to improve the blood supply to great extent Key words Myocardia infarction Atria ventricular block Atrial ventricular node artery Arrhythmia更多还原
