三项结合法在腹腔镜胆囊切除术中的临床应用

目的 探讨三项结合法（前后结合、钝锐结合、顺逆结合）在腹腔镜胆囊切除术中的应用。方法 回顾分析应用三项结合法行腹腔镜胆囊切除术5 389例的临床资料。结果 5 389例患者完成腹腔镜手术，47例患者中转开腹行胆囊切除术，所有患者均痊愈出院，无大出血、胆道损伤、胆漏、胆道狭窄等并发症发生。结论 应用三项结合法行腹腔镜胆囊切除术是一种安全可靠的手术方法，值得临床推广应用。

Global Convergence of a New Restarting Three Terms Conjugate Gradient Method for Non-linear Optimizations

In this note,by combining the nice numerical performance of PR and HS methods with the global convergence property of FR method,a class of new restarting three terms conjugate gradient methods is presented.Global convergence properties of the new method with two kinds of common line searches are proved.
