Neurogenic bowel dysfunction (NBD) manifested as constipation and fecal incontinence often occurs after spinal cord injury (SCI).NBD affects patients' quality of life and is an urgent clinical problem to be solved.The mechanism of NBD is related to central and autonomic nervous system dysfunction,intestinal nervous system dysfunction,changes in intestinal microorganism composition and abnormal content of neurotransmitters.The evaluation method of NBD is mainly based on scoring and imaging,which lacks unified criteria,and the treatment method for NBD is the combination of traditional Chinese and Western medicine.The author summarizes the mechanism,evaluation method,treatment and nursing of NBD in order to provide new insight into these aspects to improve clinical efficacy.

After the articular cartilage injury, the metabolic level is increased during the progressive degeneration, the chondrocytes secrete a variety of inflammatory factors, and the original cell phenotype is gradually changed. For a long time, a large number of researchers have done a lot of researches to promote anabolism of chondrocytes and to maintain the stability of chondrocyte phenotype. There are many molecular signaling pathways involved in the process of promoting cartilage repair. This review focuses on the key signaling molecules in articular cartilage repair, such as transforming growth factor-beta and bone morphogenetic protein, and reveals their roles in the process of cartilage injury and repair, so that researchers in related fields can understand the molecular mechanism of cartilage injury and repair widely and deeply. Based on this, they may find promising targets and biological methods for the treatment of cartilage injury.
