Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective This study aimed to investigate the protective effects of ademetionine 1,4-butanedisulfonate (SMT) against radiation injuries.Methods ICR mice were randomly divided into 7 groups,including normal control,irradiation-only,SMT administration-only,low-,medium-and high-dosages (250,500,1 000 mg·kg-1) of SMT pre-irradiation and high-dose of SMT post-irradiation in experimental groups.Blood and immunological experiments,organs index experiment and 30-day''s survival experiment were carried out to observe the protective effects of SMT on peripheral blood and immune system,organ index and the whole body injuries.Results Compared with irradiation-only group (4.23±1.16) ×109·L-1,the number of nucleated cells in bone marrow was (11.20±4.63) ×109·L-1 in the high dose of SMT pre-irradiation.The difference between two groups was significant.Compared with irradiation-only group (19.25±9.36),the colony forming unit-spleen was (39.00±7.57) in the high-dose SMT pre-irradiation group,there was a significant difference between the two groups.The index of liver,spleen,kidney and pancreas were significantly higher than those of the irradiation-only group in SMT administration groups.The survival rate of mice treated with SMT was increased,especially for the high dose group (46% lifted) when compared with irradiation-only group.Conclusion SMT can protect mice from radiation injuries.

Objective To investigate the effect of sinomenine on the purinergic receptors A2A and P2X7 in endotoxemia mouse model and RAW264.7 macrophage model stimulated by lipopolysaccharide(LPS). Methods BALB/c mice were randomly divided into blank control group, model group and sinomenine group. Thirty minutes after the rats of sinomenine group were pretreated with intraperitoneal injection of sinomenine (40, 80, 160 mg/kg), the mice were given intraperitoneal injection of 15 mg/kg LPS to induce endotoxemia model. The serum levels of tumor necrosis factor-alpha(TNF-α) and interleukin-6(IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). The expression levels of purinergic receptor A2A and P2X7 in the liver and spleen were detected by reverse transcription-polymerase chain reaction(RT-PCR). RAW264.7 macrophages were divided into blank control group, LPS group and sinomenine group. Sinomenine group was firstly treated with sinomenine(300μmol/L) for 2 h, and then LPS group and sinomenine group were treated with LPS (100 ng/mL) for another 8 hours. TNF-α in the cell supernatant was measured by ELISA, and the expression levels of A2A and P2X7 in RAW264.7 cells were detected by RT-PCR. Results Stimulation with LPS could induce the increase of the mouse serum levels of TNF-α and IL-6 as well as the expression of A2A and P2X7 in mouse liver and spleen, and sinomenine had a counteraction on the above indexes(P<0.05) . In-vitro stimulation with LPS could induce the increase of the content of TNF-α and the expression of A2A and P2X7 in RAW264.7 cells , and sinomenine decreased TNF-α content and P2X7 expression (P<0.05) , but had an effect on enhancing A2A expression. Conclusion Sinomenine suppresses the expression of purinergic receptor P2X7 in mouse spleen and liver as well as in RAW264.7 macrophages, but its effect on the expression of A2A in various tissues and cells varies, whose related mechanism is needed further study.
