Objective To analyze the MSCT features of subepithelial lesions of the urinary bladder.Methods Thirty-one patients with subepithelial lesions of the urinary bladder proved by pathology were enrolled in this study.The MSCT findings were analyzed. Results Among the 3 1 cases with subpeithelial lesions of the urinary bladder,7 cases were non-epithelial tumors (including 3 cases of leiomyomas,2 cases of paragangliomas,1 case of hemangioma and 1 case of granulocytic sarcoma),and other 24 cases were inflammatory/reactive lesions,all as cystitis glandularis.MSCT findings were as follows:paragangliomas were solitary masses with homogeneous density,smooth border and wide base,with rapid wash-in and wash-out enhancement pattern and peak enhancement in the arterial phase.Hemangiomas and leiomyomas both presented as single round mass with slight enhancement.Granulocytic sarcoma appeared as diffuse bladder wall thickening with pebble-like projections,and slight enhancement.Cystitis glandularis was characterized by local thickening of the bladder wall with nodular or aquatics-like uplift,and was also characterized by diffuse thickening,with slight and progressive enhancement in 22 cases,and significant enhancement in venous phase in 2 cases.Conclusion The subepithelial lesions of urinary bladder may present with tumor-like appearance.The key characteristic feature for cystitis glandularis is local thickening of the bladder wall with nodular or aquatics-like uplift.Rapid wash-in and wash-out enhancement pattern is considered to be diagnostically significant for paragangliomas.However,the rest of the lesions overlap in the imaging appearances,and the diagnosis should be combined with clinical manifestations to improve the accuracy of preoperative diagnosis.

TSCI have dyskinesia and sensory disturbance that can cause various life-threaten complications. The patients with traumatic spinal cord injury (TSCI), seriously affecting the quality of life of patients. Based on the epidemiology of TSCI and domestic and foreign literatures as well as expert investigations, this expert consensus reviews the definition, injury classification, rehabilitation assessment, rehabilitation strategies and rehabilitation measures of TSCI so as to provide early standardized rehabilitation treatment methods for TSCI.

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.

Lycophytes and seed plants constitute the typical vascular plants. Lycophytes have been thought to have no paleo-polyploidization although the event is known to be critical for the fast expansion of seed plants. Here, genomic analyses including the homologous gene dot plot analysis detected multiple paleo-polyploidization events, with one occurring approximately 13-15 million years ago (MYA) and another about 125-142 MYA, during the evolution of the genome of Selaginella moellendorffii, a model lycophyte. In addition, comparative analysis of reconstructed ancestral genomes of lycophytes and angiosperms suggested that lycophytes were affected by more paleo-polyploidization events than seed plants. Results from the present genomic analyses indicate that paleo-polyploidization has contributed to the successful establishment of both lineages-lycophytes and seed plants-of vascular plants.
