Methods: Following the difference in nursing style, 84 cases of elderly patients with reflux esophagitis admitted to our hospital from May 2022 to May 2023 were randomly grouped into a control group and a research group, with 42 cases each. The control group was given conventional nursing care and the research group was given refined nursing care. The psychological state and treatment adherence of the two groups of patients after the nursing intervention were compared. Results: After the nursing intervention, the self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores of the research group were lower than those of the control group (P < 0.05). The treatment compliance of the research group was better than the control group (P < 0.05). Conclusion: The implementation of refined nursing care for elderly patients with reflux esophagitis exhibited a significant effect on improving the patient’s psychological state, treatment compliance, and rehabilitation.展开更多

In clinical practice, Neiguan (PC 6) is usually selected as one of the main acupoints to treat gastrointestinal reactions induced by ① nausea and vomiting, ② hiccup, ③ gastrointestinal dyskinesia, ④ gastritis, and ⑤ intra-gastric examination, cesarean section, etc. Concerning experimental studies, the effects of Neiguan (PC 6), etc. on ① gastric electrical activities, ② gastrointestinal motion, ③ gastrointestinal hormone secretion, and ④ gastric mucosal structure were observed. Results indicated that Neiguan (PC 6) is an important and effective acupoint for treatment of gastrointestinal disorders in clinic. Stimulation of Neiguan (PC 6) induced favorable regulation of both the peripheral nervous system and central nervous system, and changes of the gastrointestinal hormone secretion may contribute to its effects in treating various disorders.展开更多
