Objective To investigate the effect of resistance training on the rehabilitation of patients after hip replacement with the framework of the theory of planned behavior(TPB).Methods A total of 85 patients of hip fracture patients in Gansu Provincial Hospital of Traditional Chinese Medicine from July 2022 to April 2023 were selected as research objects.The patients were separated into intervention group(n=43)and control group(n=42)by random sampling.Both groups were treated with routine nursing,and the intervention group was given resistance training based on TPB.The intervention time was 3 months.The Harris hip score(HHS),36-item short form(SF-36)score and Barthel index(BI)scores of the two groups were compared before intervention,1 month and 3 months after intervention,as well as the functional exercise compliance score of the patients 3 months after intervention.Results After 1 month and 3 months of intervention,the HHS,SF-36 score and BI score of intervention group were better than those of control group,and after 3 months of intervention,the executive ability of functional exercise in intervention group was significantly higher than that of control group,and the mean difference was significant(P＜0.05).Conclusion Resistance training led by TPB can effectively improve the functional exercise compliance of patients after total hip arthroplasty,improve the muscle strength,balance ability and joint stability of patients,and then improve the daily activity ability and quality of life.

Osteoporosis is a chronic skeletal disease characterized by low bone mass， destruction of bone tissue microarchitecture， and imbalance of bone homeostasis， leading to increased bone fragility and increased risk of fractures. Oxidative stress caused by the disruption of the balance between excess reactive oxygen species （ROS） and the anti-oxidative system is an important factor in the occurrence and progression of osteoporosis. Nuclear factor E₂-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） is an important anti-oxidative stress pathway. Nrf2 is a primary factor in regulating cellular oxidative stress. Activating Nrf2 can stimulate the expression of HO-1. HO-1 is a key enzyme whose metabolites are bile green Oxygen， carbon monoxide， and free iron. The metabolites can scavenge ROS， thereby exerting an antioxidant effect in cells. At present， domestic and foreign scholars have reported that the Nrf2/HO-1 signaling pathway is closely related to the occurrence and development of osteoporosis and the mechanism of drugs. Chinese medicine can effectively solve the insufficiency of western medicine with multi-target， multi-channel， and multi-level advantages. Chinese medicine can resist oxidative stress， inflammatory response， and apoptosis by regulating the Nrf2/HO-1 signaling pathway， thus treating osteoporosis. This article reviewed the relationship between Nrf2/HO-1 signaling pathway and its key target protein factors and osteoporosis， to clarify the important role of the Nrf2/HO-1 signaling pathway in osteoporosis. At the same time， a systematic summary of Chinese medicines targeting and regulating the Nrf2/HO-1 signaling pathway for the treatment of osteoporosis was conducted， to provide a theoretical basis for further precise treatment of osteoporosis.
