With the widespread application of drug-eluting stent(DES)technology and rapid advancement in stent bioengineering,the efficacy and safety of percutaneous coronary intervention(PCI)have significantly improved.Howev-er,the incidence of in-stent restenosis(ISR)remains a critical issue,with approximately 1％to 2％of patients requiring repeat revascularization annually.Given the global implantation of millions of DES each year,ISR has emerged as a major clinical challenge demanding urgent resolution.The pathological mechanisms underlying DES-ISR are complex and heter-ogeneous,and with continuous progress in intracoronary imaging techniques,these mechanisms and classifications have been further elucidated.Concurrently,therapeutic tools and strategies for ISR are undergoing ongoing development and optimization.This review summarizes recent research progress and achievements in the definition,classification,patho-logical mechanisms,imaging characteristics,and treatment approaches related to DES-ISR.

Objective To analyze the changes of neutrophil-to-albumin ratio(NPAR),monocyte-to-lymphocyte ratio(MLR),neutrophil-to-lymphocyte ratio(NLR)and interleukin-17A(IL-17A)in patients with severe autoimmune encephalitis(AE)and the predictive value of their combined detection for prognosis.Methods A total of 105 patients with severe AE admitted from May 2021 to April 2025 were selected as the severe group.During the same period,35 patients with mild-to-moderate AE and 35 healthy controls were enrolled in a 3:1:1 ratio as the mild-to-moderate group and control group respectively.The levels of NPAR,MLR,NLR and IL-17A were compared among the three groups.Patients with severe AE were observed for one month.According to the prognosis of patients,they were divided into poor prognosis subgroup[modified Rankin scale(mRS)score≥3,n=31]and good prognosis subgroup(mRS score<3,n=74).The levels of NPAR,MLR,NLR and IL-17A in the two groups were compared,to analyze the correlation between NPAR,MLR,NLR and IL-17A levels and mRS score in patients with severe AE,and to evaluate the predictive value of combined detection of the four indicators for prognosis in these patients.Results The levels of NPAR,MLR,NLR and serum IL-17A in mild-to-moderate group and severe group were higher than those in control group,which were higher in the severe group than in the mild-to-moderate group(P<0.05).The course of disease in the poor prognosis group was longer than that in the good prognosis group,and the proportion of patients with γ-aminobutyric acid B receptor antibody and the levels of NPAR,MLR,NLR and serum IL-17A were higher than those in the good prognosis group(P<0.05).Higher levels of NPAR,MLR,NLR and serum IL-17A were all risk factors for poor prognosis of patients with severe AE(OR=2.445,4.319,2.502,1.791,P<0.05).The levels of NPAR,MLR,NLR and serum IL-17A were positively correlated with the mRS score of patients with severe AE(r=0.546,0.519,0.554,0.561,P<0.001).The area under the receiver operating characteristic(ROC)curve(AUC)of NPAR,MLR,NLR and IL-17A detected in combination in predicting the prognosis of patients with severe AE was higher than that of the four indicators detected alone(P<0.05).Conclusion The changes in NPAR,MLR,NLR and IL-17A levels in patients with AE were closely related to the severity and prognosis of the disease.In the meantime,higher levels of NPAR,MLR,NLR and serum IL-17A were risk factors for poor prognosis,and the combined detection of the four indicators could effectively improve the predictive value for prognosis in patients with severe AE.

Human immunodeficiency virus(HIV)is the pathogen of acquired immune deficiency syndrome(AIDS).The vi-rus is a highly contagious and highly pathogenic disease caused by the virus attacking the human immune system,which remains a ma-jor global public health problem.Interferon(IFN)is a key cytokine with antiviral and cell-regulatory properties,involved in functions such as cell proliferation,innate and adaptive immune responses.The JAK/STAT signaling pathway is a signal transduction pathway stimulated by cytokines that is involved in many important biological processes such as cell proliferation,differentiation,apoptosis,and immune regulation.With the further in-depth research on AIDS,it has been revealed that IFN and the JAK/STAT pathway play crucial roles in the activation and replication of HIV-1 in target cells.This paper summarizes the structure,signal transduction,and regulatory mechanisms of IFN and the JAK/STAT pathway,and explores the mechanism of IFN-regulated JAK/STAT signaling path-way in HIV-1.It is expected to provide new treatment strategies for the clinical treatment of AIDS.
