RESUMO
Objective To investigate the result of diagnosis and surgery of stageⅠnon-small cell lung cancer (NSCLC).Methods The survival of 47 stageⅠNSCLC patients performed surgery were retrospectively analyzed.Results There were 21 cases who were diagnosed by routine physical examination.The 1～,3～,5～year survival rates of the group of lobectomy were 93.8%,79.3% and 54.6% respectively.The1～,3～,5～year survival rates of wedge resection were 75.7%,42.6% and 35.7% respectively.There were statistical significances of the survival rates between the two groups(P
RESUMO
Objective To investigate the myocardial protective effects of“integrated strategy”with HOE-642 plus modified K/Mg on canine heart grafts.Methods Sixteen donors-recipient pairs of adult canines were divided into the“integrated strategy”group,i.e.,donor hearts were protected with HOE-642 plus K/Mg(IS,n=8)and the routine method(RM,n=8)group.Both groups un- derwent hypothermia stored for 4 h,followed by orthotopic transplantation.Cardiac heamodynamics was measured and myocardial ultrastructure and myocardial water content were evaluated.Results One of 8 animal died of aortic anastomoses leakage in each group,and the rest could wean from car- diopulmonary bypass successfully.Preservation of left ventricular contractility,as well as left ventric- ular compliance was significantly better in the IS group than in the RM group(P＜0.05),also,per- centage of myocardial water content was significantly lower in the IS group than in the RM group(P＜0.05).Myocardial ultrastructures were not damaged significantly in both groups,however,better myocardial preservation were seen in the IS group.Conclusion Both the clinically used“routine meth- od”and“integrated strategy”might provide safe donor heart preservation for 4 h,but the later scheme conferred more optimal effects with alleviating the myocardial swelling,preserving myocardial ultra- structure integrity and enhancing postischemic-reperfusion cardiac functional recovery.
