ABSTRACT
BACKGROUND:Cell death and neuroinflammation are two important targets in the treatment of spinal cord injury.Pyroptosis is a programmed cell death closely related to neuroinflammation and targeted inhibition of pyroptosis after spinal cord injury is a promising therapeutic strategy. OBJECTIVE:To summarize the molecular mechanism,positive and negative regulatory factors and therapeutic strategies of pyroptosis in spinal cord injury. METHODS:The search terms were"spinal cord injury,pyroptosis,nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3),Caspase,Gasdermin D(GSDMD),IL-1β,IL-18"and 93 English literatures included in PubMed and Web of Science were finally selected for review. RESULTS AND CONCLUSION:As a newly discovered programmed cell death,pyroptosis has been shown to play an important role in the secondary injury stage after spinal cord injury.Among the regulatory factors of pyroptosis after spinal cord injury,CD73,NRF2,GDF-11,dopamine,FANCC and miR-423-5P could inhibit pyroptosis,while TLR4 and Aopps could promote pyroptosis.In terms of treatment,the active ingredients of traditional Chinese medicine(paeonol,tripterine,betulinic acid,piperine,kaempferol,and camptothecin),exosomes of various cell origins,and some drugs(metformin,topotecan,lithium,zinc,and carbon monoxide-releasing molecule 3)can effectively inhibit pyroptosis and reduce secondary spinal cord injury,but the toxicity and specific dose of these drugs need to be further studied.The specific molecular mechanism by which pyroptosis aggravates spinal cord injury is still poorly understood.The role of non-classical pathways and other inflammasomes is worth further exploration.At present,the research on pyroptosis after spinal cord injury only stays at the animal experiment stage.There are no related clinical studies and no approved targeted therapeutic drugs.(6)The application of pyroptosis after spinal cord injury has great potential,and its specific regulatory mechanism should be further studied in the future to provide a new target for the treatment of spinal cord injury.
ABSTRACT
Since smart phones have been developed, significant advances in the function of mobile phone due to the development of software, hardware and accessories have been reached. Till now, smart phones have been engaged in daily life with an increasing impact. As a new medical model, mobile phone medicine is emerging and has found wide spread applications in medicine, especially in diagnosing, monitoring and screening various diseases. In addition, mo bile phone medical application shows great potential trend to improve healthcare in resource-limited regions due to its advantageous features of portability and information communication capability. Nowadays, the scientific and technological issues related to mobile phone medicine have attracted worldwide attention. In this review, we summarize state-of-the-art advances of mobile phone medicine with focus on its diagnostics applications in order to expand the fields of their applications and promote healthcare informatization.
