有关胃粘膜保护机制的研究正日益受到人们的重视。使用传统抑酸剂治疗胃溃疡，溃疡复发率很高，即使使用质子泵抑制剂，溃疡复发问题仍未能得到解决；幽门螺杆菌（Ｈ．ｐｙｌｏｒｉ）虽与溃疡病关系密切，但大多数感染Ｈ．ｐｙｌｏｒｉ者并不发生溃疡，证明胃粘膜自身防御机制? Research on the mechanism of gastric mucosal protection is gaining more and more attention. The use of traditional antacids in the treatment of gastric ulcer, ulcer recurrence rate is high, even with proton pump inhibitors, ulcer recurrence has not been resolved; H.pylori (H.pylori) is closely related with ulcer disease, but most infections H. Pylori does not occur ulcers, gastric mucosal defense mechanism to prove its own?
