ABSTRACT
Objective To summarize the experience of surgical treatment of venous drug-induced infective endocarditis(IE). Methods The 17 cases of drug-induced IE were found to have valvular vegetations,16 patients had involvement of tricuspid valve, 1 mitral valve associated with ventrieular septal defect. Preoperative blood culture was positive in 8 patients. The operations included tricuspid valve repair (6 cases),tricuspid valve replacement(8 cases), mitral valve replacement and VSD closure(1 cases). Results All patients were alive and discharges. After follow-up of 6 months to 6 years, 1 case had severd tricuspid alve regurgitation, 1 had haemoptysis because of incorrect anticoagulation. Conclusions This study indicated surgical intervention is effective treatment of venous drug-induced infective endocarditis.
ABSTRACT
Objective To summarize clinical data of 33 patients with off-pumb coronary artery bypass grafting(OPCABG) procedure and analyze the benefit and curative effects of OPCABG procedure. Methods From February 2002 to June 2005,33 patients with cardiac function in class Ⅱ-Ⅲ (NYHA) and left ventricular ejection fraction(LVEF) was 34%-68%,and all of them underwent coronary artery bypass grafting(CABG) surgery without cardiopulmonary bypass. Results After operation,There was no death, the cardiac function improved in various degree. Preoperative angina disappeared. Conclusion OPCABG procedure is a safe, available, effective method for coronary artery disease.
ABSTRACT
Objective To investigate the change in natural kill cell,T-ly mphocyte subset counts and effect of recovery after homologous and autologous blood transfusion.Methods 50 patients undergoing lung cancer operation were randomly divided into two groups:group A received autologous blood transfusion with 400ml and group H received homologous blood transfusion with 400ml.Venous blood samples were taken before surgery,before blood transfusion and on the 1st and 5th postoperative day for determination of T-ly mphocyte subsets and natural kill cell counts by flow cytomet.The existent ratio of 1～3 years were followed up.Results The NK cell,CD+_3 and CD+_4 counts and CD+_4/CD+_8 ratio decreased significantly on the 1st postoperative day in both groups(P
