There were 114 cases in the first group, 76 cases of duodenal ulcer, 56 males and 20 females, with an average age of 40.1 years. 38 cases of gastric ulcer, 28 males and 10 females, with an average age of 45.9 years. In the ulcer disease exacerbation period, the semiconductor laser was used to directly irradiate the ulcer area through the endoscopic optical fiber. The infrared wavelength was 960 nm and the interval was 2 to 3 d, and the ulcer healed. Group 2 82 cases, 64 cases of duodenal ulcer, male 43
