Objective: To analyze the existing problems in the construction of pneumoconiosis rehabilitation station in Beijing under the framework of ecosystem theory, and put forward countermeasures. Methods: A total of four managers directly involved in the construction of three pneumoconiosis rehabilitation stations in Beijing and 12 rehabilitation doctors working in rehabilitation stations were selected as the interviewees using the judgment sampling method. Based on the perspective of ecosystem theory, an interview outline was designed to conduct a semi-structured interview with the interview subjects. In combination with literature data, the current situation, existing problems and solutions of pneumoconiosis rehabilitation station construction were analyzed. Results: There were still deficiencies in the construction of pneumoconiosis rehabilitation stations in Beijing. At the microscale level, pneumoconiosis patients could not make full use of family resources for active and effective pulmonary rehabilitation treatment, and family members lack of effective rehabilitation guidance and assistance for patients. At the medium-scale level, the resources of primary rehabilitation institutions were insufficient, the medical support for pneumoconiosis rehabilitation was insufficient, and the pneumoconiosis rehabilitation stations lacked a unified information management and technology platform. At the macroscale level, it has not established clear and specific requirements for the construction management and evaluation of pneumoconiosis rehabilitation stations, and there was social discrimination and prejudice against pneumoconiosis patients. Conclusion: It is necessary to improve the recognition of rehabilitation in primary medical and health institutions, strengthen education on the awareness of the disease and rehabilitation skills guidance for patients and their families, strengthen the responsibilities of technical support institutions in rehabilitation stations, promote the construction of primary rehabilitation stations and personnel training, make full use of information technology, promote information exchange and knowledge sharing, and ensure the quality of rehabilitation of pneumoconiosis.

Diarrhea is a common and frequent disease in clinical practice.Many factors cause diarrhea,and numerous research method with animal models of diarrhea have been explored.Despite this,drugs for the treatment of diarrhea in clinical practice are limited,and some existing drugs are only suitable for diarrhea caused by a single factor.Therefore,the construction and selection of appropriate animal models of diarrhea are not only important for in-depth studies of the pathogenesis,but are also effective means for the clinical screening and evaluation of drugs for comprehensively preventing and treating diarrhea.This article reviews the literature on the establishment and evaluation of animal models of functional,bacterial,viral,and symptomatic diarrhea,as well as progress of therapeutic drug research,to provide a reference for animal experimental research into the prevention and treatment of diarrhea.
