十二指肠球部溃疡的治疗最主要的是（）。胃溃疡恶变的治疗（）。防止溃疡复发的最主要的措施是（）。
A.抑制胃酸分泌
B.保护胃粘膜
C.早期手术
D.减少胆汁反流
E.根除幽门螺杆菌（Hp）
参考答案：A,C,E
解析：
【考点】消化性溃疡的治疗。消化性溃疡的最终形成是由于胃酸-胃蛋白酶自身消化所致，这一概念即使在"Hp时代"仍未改变。而十二指肠溃疡患者的平均基础酸排量（BAO）和五肽促胃液素等刺激后的最大酸排量（MAO）常大于正常人，所以对十二指肠球部溃疡的治疗最主要的是抑制胃酸分泌；目前对溃疡恶变的主要治疗手段仍是手术切除；Hp感染是影响溃疡复发的可去除的危险因素，所以根除Hp是主要的预防办法之一。
