AIM:To investigate the effect of hydrogen sulfide ( H2 S) on high glucose ( HG)-induced injury of the mouse podocyte cell line MPC5.METHODS: The cultured MPC5 cells were randomly divided into 4 groups: HG group, normal glucose (NG) group, NG+DL-propargylglycine (PPG) group, and HG+NaHS group.After treated for a certain time, the cells were collected for further detection .The expression of zonula occludens-2 (ZO-2), nephrin,β-cate-nin and cystathionine γ-lyase ( CSE) was determined by Western blotting .RESULTS:High glucose significantly reduced the expression of nephrin, ZO-2 and CSE (P<0.05), while the level of β-catenin was elevated obviously (P<0.05), all in a time-dependent manner.NG+PPG inhibited the levels of ZO-2 and nephrin significantly (P<0.05), and increased the level of β-catenin (P<0.05), all in a PPG concentration-dependent manner.HG+NaHS induced a more significant increase in the levels of ZO-2 and nephrin as compared with HG group (P<0.01), whereas a severe reduction of β-cate-nin in HG+NaHS group was observed as compared with HG group .Compared with NG group , the expression of ZO-2 and nephrin was decreased obviously , and the level of β-catenin was increased in HG +NaHS group.CONCLUSION:Down-regulation of CSE contributes to hyperglycemia-induced podocyte injury .Exogenous H 2 S protects against hyperglycemia-in-duced podocyte injury , possibly through up-regulation of ZO-2 and subsequent suppression of Wnt/β-catenin pathway .

Hypoxic-ischemic encephalopathy(HIE)is a major cause of newborn mortality and childhood disability.Despite hypothermia treat-ment being the current standard method,it has its limitations and often produces unsatisfactory out-comes.Additionally,due to time and equipment constraints,hypothermia treatment cannot be promptly administered,leading to high mortality rates or varying levels of neurological impairments even after treatment.Hence,the exploration of al-ternative and effective treatment methods for HIE has become a challenging and highly researched topic in the field of neonatology.Research has shown that HIE induces intricate changes in the neurological system at the physiological,cellular,and molecular levels.Circular RNA(circRNA)exhib-its high expression in the central nervous system and plays a role in regulating physiological and pathophysiological processes.Therefore,circRNA holds promise as a potential therapeutic target for HIE.This article provides a comprehensive over-view of the regulatory effects of circRNA on differ-ent types of neural cells in HIE,aiming to offer new theoretical foundations for the treatment of HIE.

Ischemic stroke has always been a thorny problem in the field of cerebrovascular research due to its complex injury mechanism,high incidence,and disability rate.It is essential to find new and effective interventions and neuroprotective strategies.Interleukin-33(IL-33),as one of the newly discovered members of the IL-1 family,is currently the focus of global academic research,and serum stimulation-2(ST2)is the main receptor for its action.In this paper,the current research status of the IL-33/ST2 signaling pathway in ischemic stroke was reviewed,to clarify the protective mechanism of IL-33/ST2 signaling pathway in ischemic stroke,including amplification of regulatory T cell,regulation of inflammation,and improvement of white matter,to provide new ideas for the treatment of ischemic stroke.
