Objective To explore the influencing factors forcerebral small vessel disease(CSVD)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 160 patients with T2DM admitted to the Department of Endocrinology our hospital were enrolled in this study from January 2024 to March 2024,and divided into simple T2DM group(n=107)and T2DM combined with CSVD(CSVD,n=53)group according to the combination of CSVD.The general information and biochemical indicators were compared between the two groups.Logistic regression analysis was used to analyze the influencing factors for CSVD in patients with T2DM,and ROC curve was used to evaluate the diagnostic efficacy of CSVD markers.Results The CSVD group showed significantly higher values than the T2DM group(P<0.05)in the following parameters:DM duration,serum uric acid,cystatin C(CysC),neutrophils,monocytes,C-RP,monocyte-to-high-density lipoprotein cholesterol ratio(MHR),and PAC-1 levels.Conversely,the CSVD group had significantly lower levels of LDL-C,lymphocytes,and albumin-to-globulin ratio(A/G)compared to the T2DM group(P<0.05).Logistic regression analysis indicated that A/G,CysC,MHR,and DM duration were influencing factors for T2DM complicated with CSVD.Receiver operating characteristic(ROC)curveanalysis demonstrated that the combined prediction model incorporating A/G,CysC,MHR,and DM duration yielded an area under the curve of 0.88,indicating good predictive performance.Conclusions A/G,CysC,MHR,and duration are independent risk factors for CSVD in patients with T2DM.Early identification of these items may facilitate the prevention of CSVD in patients with T2DM.

Objective:To investigate the effect and mechanism of donor-Ag specific T cell vaccination on inducing specific immune tolerance of allogenic liver transplantation and the mechanism of immune privilege of liver transplantation .Methods:CBA mice were recipients,B6 mice were donors,T cell vaccination (TCV) were made from the attenuated spleen cells of CBA mice ,which were stimulated by Con A and were challenged with the spleen cells of B 6 mice.There are 3 groups in this experiment:Transplant control group:Orthotopic liver transplantation ( OLT) were performed with the recipients of CBA mice and donors of B 6 mice;Flt3-L treating group:OLT were performed with the recipients of CBA mice and donors of B 6 mice treated with Flt3-L;TCV group:OLT were performed with the recipients of CBA mice inoculated with TCV and donors of B 6 mice treated with Flt3-L.Median survival time (MST) of liver grafts was recorded, IL-4, IL-10 and IFN-γin peripheral blood were tested after transplantation in each group .One-way mixed lymphocyte reaction ( MLR) were carried out with effectors of spleen cells from CBA mice and stimulator of spleen cells from B 6 mice at the 5th day after transplantation.The apoptosis of liver graft infiltrating cells (GICs) were analyzed by flow cytometric analysis at the 5th day after transplantation.Results: Flt3-L treating donor activated allogenic acute rejecting reaction , TCV vaccinating recipient before and after transplantation significantly depressed the acute immune rejecting reaction mediated by Flt 3-L.The liver grafts were accepted by recipient without the presence of Flt 3-L.The cytokines test show that the serum value of IL-4 and IL-10 were increased in Transplant control group and TCV group ,but decreased in Flt3-L treating group.The value of IFN-γwas increased in Flt3-L treating.
