Objective To conduct a systematic study on the potential impact of long-term specialized golf training on the three-dimensional structure of the spine in adolescent children,and to reveal the biomechanical adaptation mechanism of children's spine,providing a theoretical basis for preventing potential sports injuries caused by golf training.Methods A longitudinal observational design was adopted,with 15 male adolescent children from a golf training center selected as research subjects.Three-dimensional spinal image data were collected using digital radiography at baseline,3 months and 6 months,and dynamic monitoring and analysis were performed.Results Golf training led to a series of adaptive changes in the three-dimensional structure of children's spine,mainly reflected in significant changes in pelvic tilt distance,vertebral body offset,vertebral rotation angle,pelvic rotation angle,and pelvic torsion angle.These changes exhibited a time-effect characteristic,indicating the strong adaptability of biomechanical system of children's spine.Conclusion Golf training can cause adaptive changes in the three-dimensional structure of children's spine,highlighting the need to maintain biomechanical balances of the spine and pelvis,and to take intervention measures such as symmetrical training to prevent sports injuries,improve training quality,and prolong athletic careers.

Objective To investigate the clinical effect of traditional Chinese medicine syndrome differentiation-based treatment combined with entecavir in the treatment of chronic hepatitis B. Methods A total of 80 outpatients with chronic hepatitis B were randomly divided into the observation group (n=40) and control group (n=40).The patients in the control group were treated with entecavir tablets. The patients in the observation group were given TCM syndrome differentiation-based treatment in addition to the treatment received by the control group. Clinical symptoms relief, improvement of liver function indexes, serological conversion and HBV-DNA negative rate were compared between the two groups after 48 weeks of treatment. Results The clinical symptoms of abdominal distension, fatigue, pain and anorexia were relieved better in observation group than in control groups. The difference was significant between the two groups (P<0.05). The observation group had significant therapeutic advantages over the ALT recurrence rate compared to the control group, especially 24 weeks ago (P<0.05). There was no statistically significant difference between the combined group and the control group after 12, 24, 48 weeks after treatment, and the HBV-DNA (both greater than 0.05) were clinically modified. Conclusion TCM syndrome differentiation-based treatment combined with entecavir had significant therapeutic advantages in the treatment of chronic hepatitis B, which could relieve clinical symptoms, improve liver function indexes, and converse serological changes and be worthy of clinical popularization.
