目的探讨幽门螺杆菌（Ｈｐ）感染在功能性消化不良（ＦＤ）患者胃排空功能障碍中的作用．方法采用放射性同位素γ－照相法观测了５６例ＦＤ患者胃固－液体排空情况，并用胃窦粘膜印片Ｇｉｅｍｓａ染色及石蜡切片ＨＥ，Ｗ＿Ｓ银染色镜检Ｈｐ．结果ＦＤ患者餐后３０，６０及９０ｍｉｎ时的胃排空率均显著低于正常对照组（Ｐ＜００５－００１）；ＦＤ患者Ｈｐ感染率无明显增高（Ｐ＞００５），Ｈｐ阳性组与阴性组在３个时相的胃排空率差异均无显著性（Ｐ＞００５）结论ＦＤ患者胃排空功能与Ｈｐ感染无关
Objective To investigate the role of Helicobacter pylori (Hp) infection in gastric emptying dysfunction in patients with functional dyspepsia (FD). Methods Gastric-fluid emptying in 56 patients with FD was observed by radioisotope γ-photogrammetry. Gemsa staining and paraffin section HE staining were performed on antral gastric mucosa, and Hp was detected by silver silver staining. Results The gastric emptying rate of FD patients at 30, 60 and 90 min after meal was significantly lower than that of the normal control group (P <005-001). The incidence of Hp infection in FD patients was not significantly higher (P0.05) There was no significant difference in gastric emptying rate between Hp positive group and negative group at 3 time points (P> 005). Conclusion The gastric emptying function in FD patients was not related to Hp infection
