摘要
目的探讨细胞凋亡在幽门螺杆菌（Ｈｐ）阳性胃十二指肠疾病中的意义。方法用原位凋亡细胞观察Ｈｐ对胃上皮细胞凋亡的影响。结果在Ｈｐ（＋）胃十二指肠疾病，除胃癌外均比Ｈｐ（－）的细胞凋亡率高，其顺序是十二指肠溃疡＞胃溃疡＞浅表性胃炎＞萎缩性胃炎＞胃癌。十二指肠溃疡和胃溃疡还可见到梯状ＤＮＡ现象。结论Ｈｐ可诱导细胞凋亡；细胞凋亡与细胞增殖失衡程度和水平的不同，有可能是导致不同的胃十二指肠疾病的原因之一。
Objective To
explore the significance of cell apoptosis in gastroduodenal diseases infected with H.pylori.
Methods The effects of H.pylori on the gastric epithelium were percieved by in situ apoptosis
detection and DNA ladder pattern. Results By the use of in situ apoptosis detection, its rate in
various gastroduodenal diseases infected with H.pylori except for gastric carcinoma was higher
than in those uninfected. It was in decreasing order of duodenal ulcer>gastric ulcer>superficial
gastritis>atrophic gastritis>gastric cancer. The DNA ladder could be observed in duodenal ulcer
and gastric ulcer patients. Conclusions H.pylori may enhance cell apoptosis, and perhaps
result in a diversity of gastroduodenal diseases due to the imbalance of apoptosis and cell
proliferation.
