Objective To investigate the effect of therapy on the patients of gastric ulcer by antrectomy ulcer locally excision with anti-helicobacter pylori drugs.Methods According to the principal of vertical incision and parallel suture,the ulcer was locally existed by parallel axis.The area beyond the margin of ulcer one centimeter must be resected,26 cases have been performed the antrectomy retaining pylorus and gastroduoden-cstomy.After operating all of the patients had taken anti-helicobacter pylori drugs for 21 days.Results We follow up this group of patients for 5 years.Symptom that occurred preoparation disappeared in 24 cases and patients' weight increased.2 patients performed preservative therapy of posthepatitis cirrhosis.After 5 years all of them had been taken gastr ofiberscope reexamination and the result of no recurrence of ulcer and HP negative.Conclusions This method is a simple and safe procedure with quite small injury.It prevents recurrence and is fit for the physiology of human body with few postoperative complication and retain pylorus.

Objective To study the relationship between the change of T lymphocyte subsets and NK cells in esophageal cancer patients and radiotherapy effect.Methods The levels of T lymphocyte subsets and NK cells were detected by flow cytometry in 56 cases with histologically confirmed esophageal cancer treated with radiotherapy and contrasted to the healthy people.Results In patients with esophageal cancer,peripheral blood T cells,Th cells,Th / Ts were decreased significantly compared with the control group [(58.3±5.2) ％ vs (65.8±7.2) ％,(28.7±5.0) ％ vs (38.1±7.7) ％,(1.0±0.3) vs (1.6+2.7),all P ＜ 0.05],while the Ts cells were significantly increased [(28.8±5.3) ％ vs (25.4±5.7) ％,P ＜ 0.05].There was no significant difference between peripheral blood T lymphocyte subsets,Th/Ts ratio change and patient age,sex,tumor staging,histological differentiation and pathological lesions.After radiotherapy,the levels of peripheral blood T cells,Th cells,Th/Ts cell ratio and NK cells in esophageal cancer patients were increased [(66.9±4.5) ％ vs (59.4±4.9) ％,(40.6±5.6) ％ vs (29.1±4.2) ％,(1.6+0.5) ％ vs (1.0±0.4) ％,(16.2±3.9) ％ vs (14.6±3.2) ％,all P ＜ 0.05],while the Ts cells decreased [ (25.4±3.6) ％ vs (28.4±5.7) ％,P ＜ 0.05].The increasing degree of peripheral blood T cells,Th cells were closely related to the lesion progress,the difference was significant (both P ＜ 0.05).Conclusion Cellular immune function in patients with esophageal cancer is low.Detection of T lymphocyte subsets,NK cells can be used for immune monitoring of patients with esophageal cancer.
