Acute urinary retention(AUR)occurs frequently among astronauts on orbit.The current treatment is complex and easy to damage the urethra,which seriously affects the life and work of astronauts.In contrast,acupuncture,a traditional Chinese remedy,has shown promising results in managing urinary retention.However,the specific acupoints that could potentially prevent AUR remain uncertain due to the unique physiological conditions experienced by individuals in space compared to those on Earth.To address this gap,our research delved into the mechanisms of AUR and acupuncture within both traditional Chinese medicine and modern medical practices.We conducted a thorough literature review from Pubmed,Web of Science,CNKI,Wanfang database,VIP database and Chinese Medical Code database.A hierarchical evidence-scoring approach was utilized to analyze the included literatures,thus devised acupuncture protocols for the treatment of AUR.The outcomes of our study aim to establish a foundation for the application of acupuncture in managing AUR.

Astronauts are affected by the space environment,and there are health problems in many systems of the body,which seriously affect the on-orbit work efficiency and the health recovery after landing.Although measures have been taken,there are still deficiencies.Acupuncture can regulate the body in a multi-target,multi-level and multi-system way to protect the health of astronauts,which is an effective measure to protect the health problems of astronauts.But there is no acupoint group database for aerospace medical problems,which limits the application of acupuncture in space.The aim of this paper is to solve the possible aerospace medical problems of astronauts by acupuncture.Firstly,the acupuncture indications in aerospace medicine are determined through literature research,expert consultation and expert consensus,and then the evidence collection,evidence evaluation and evidence aggregation are carried out through the"stratified evidence evaluation method"for ancient literature,modern literature and expert experience.Finally,acupoint prescriptions were recommended based on the comprehensive score of acupoints,and acupuncture prescriptions for all acupuncture indications in aerospace medicine were integrated to form an acupoint group database,so as to contribute more Chinese wisdom and solutions to solve aerospace medicine problems.

Objective To explore the expression of basic fibroblast growth factor(bFGF) in pulmonary tissues of rats with bleomycin-induced pulmonary fibrosis and the role of bFGF in vascular injury.Methods Pulmonary fibrosis was induced in rats by intratracheal injection of bleomycin(BLM).Lung expression of bFGF proteins was assessed by SABC immunohistochemistry using bFGF monoclonal antibody and quantitative image analysis.Results The expression of bFGF in the lung tissues of BLM group was mainly distributed in bronchiole epithelial cells,muscular layers of bronchi and arterioles,and alveolar macrophage.It was higher than that in control group,with significant difference(P
