Chemotherapy as a routine method for clinical treatment of cancer has disadvantages such as significant toxicity and strong resistance. In order to improve the efficacy of the drugs and reduce the by-effects, we tried to combine static magnetic field (SMF) with cisplatin or adriamycin. The growth of Hepa1-6 cells treated with the static magnetic field (SMF) combined with cisplatin or adriamycin was significantly inhibited, as detected with MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide) test. Combined treatment group cells underwent significant morphological changes as observed by HE (Hematoxylin and eosin) staining under optical microscope. Cell cycle analysis indicated that SMF increased the ratio of cells arrested in G2/M phase caused by cisplatin, and when treated with SMF combined with adriamycin, cells were almost arrested in G1 and G2/M phase. SCGE test showed that SMF can enhance the ability of cisplatin or adriamycin to promote cell DNA damage. Atomic force microscope observation found that the combination of antitumor drugs and magnetic field treatment induced larger and deeper holes on the cell membrane, and surface structure damage is serious. The combination of antitumor drugs and magnetic field technology effectively inhibits the growth of tumor cells, and reduces drug doses. The results implicate this method as potential cancer therapy.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
