Objectives This study aimed to assess the effects of modified pulmonary rehabilitation (PR) on patients with moderate to severe chronic obstructive pulmonary disease (COPD). Methods A total of 125 patients (63 in the PR group and 62 in the control group) were recruited in this study. The patients in the PR group received 12 weeks of conventional treatment, nursing, and modified pulmonary rehabilitation, while the patients in the control group underwent 12 weeks of conventional treatment, nursing, pursed-lip breathing training, and abdominal breathing training. Baseline characteristics, St. George's Respiratory Questionnaire (SGRQ), the six-minute walk test (6MWT), modified medical research council (MMRC) dyspnea scale, and lung function were compared between the two groups. Results A total of 112 patients (58 patients in the PR group and 54 patients in the control group) completed the 12-week monitoring and follow-up. The SGRQ scores, symptoms (54.933 ± 11.900), activity (52.644 ± 14.334), impact (55.400 ± 9.905), and total score (54.655 ± 10.681) of the PR group did not significantly differ in pre- and post-treatments ( P < 0.05). No significant change was also observed in the control group ( P > 0.05). 6MWT [(372.089 ± 67.149) m] was significantly improved in the PR group ( P < 0.05) but was not significantly different in the control group ( P > 0.05). MMRC (actual rank sum 1719, rank sum 2047.5) was significantly reduced in the PR group ( P < 0.05) but not in the control group ( P > 0.05). The lung function (FVC, FEV1, FEV1/FVC, FEV1% and PEF) of the patients in both groups did not significantly change ( P > 0.05). Conclusion Modified PR reduces the symptoms of dyspnea, increases exercise capacity, and improves the quality of life of patients with moderate to severe COPD.

This study mainly analyzes the related surgical and psychological factors that cause the change of thirst degree after gastrointestinal surgery, and observes the practical effect of action intervention strategy combined with the two factors on reducing postoperative thirst degree. Based on this, the clinical data of 87 patients who underwent gastrointestinal tumor resection in our hospital from January 2020 to January 2021 is retrospectively analyzed. The degree of thirst is evaluated by the visual analogue scale (VAS) and the subjects are divided into three groups: a mild group (n = 29), a moderate group (n = 35), and a severe group (n = 23), and their psychological and surgical indicators are compared and analyzed. The results show that the thirst degree and light comfort of mouth in the study group are better than those in the control group at 2 h after surgery, and there is no significant difference when compared to 6 h after surgery, but the thirst degree and oral discomfort in the control group at 6 h after surgery are significantly higher than those in the study group at 2 h after surgery. It is suggested that an action research intervention strategy with a high practical effect can effectively reduce postoperative thirst and oral discomfort.
