Objective To compare the clinical efficacy and safety differences between the triple immunosuppressive regimen of mizoribine (MZR) or mycophenolate mofetil (MMF) combined with tacrolimus (Tac) and glucocorticoids of kidney transplant recipients in one year after transplantation. Methods A single-center retrospective cohort study design was adopted. The clinical data of 156 patients who underwent the first allogeneic kidney transplantation at the Third Hospital of Peking University from January 2022 to December 2024 were included. The patients were divided into the MZR group (78 cases) and the MMF group (78 cases) based on the initial immunosuppressive regimen after transplantation. The baseline data, medication use in one year after transplantation, blood routine indicators, adverse events and clinical outcomes were compared between the two groups. For the repeated-measurement longitudinal data, repeated-measurement analysis of variance was used to evaluate the main effects of the groups, time and their interaction effects. Results At the primary efficacy endpoint, there were no statistically significant differences in the one-year survival rate, graft survival rate and incidence of acute rejection between the two groups (all P > 0.05). In terms of medication patterns and laboratory test indicators, there were significant time main effects and "time × group" interaction effects for Tac dosage (all P < 0.05). The Tac dosage in the MZR group was lower than that in the MMF group from 2 to 3 months after transplantation, and it was higher in the MZR group than in the MMF group from 7 to 12 months and one year after transplantation. White blood cell count in the MZR group was higher at one month after transplantation, and the platelet count was higher one year after transplantation (all P < 0.05). In terms of infection, the incidence of novel coronavirus and Pneumocystis jirovecii pneumonia infections in the MZR group was lower (all P < 0.05). In terms of metabolic indicators, the post-transplantation uric acid level was better in the MZR group than in the MMF group, but the total cholesterol level was higher one year after transplantation (all P < 0.05). In terms of liver function, there was a brief and mild increase in transaminase in the early stage after transplantation in the MZR group. Conclusions During the one-year follow-up after transplantation, both the MZR and MMF regimens demonstrate comparable immunosuppressive efficacy and overall safety in Chinese kidney transplant recipients. The MZR regimen shows clear advantages in reducing specific infection risks, alleviating bone marrow suppression and improving uric acid metabolism, but its potential impact on blood lipids needs to be monitored. Therefore, the MZR regimen may be an effective and safe alternative immunosuppressive option for kidney transplant recipients, especially those with high infection risk, poor hematological tolerance, or comorbid hyperuricemia.

OBJECTIVE To develop a nomogram model for prediction of the risk of sepsis in the patients with acute liver failure(ALF)and validate its clinical value.METHODS Totally 228 patients with ALF who were treated in the Fifth Medical Center of Chinese PLA General Hospital from Jan.2009 to Mar.2023 were recruited as the re-search subjects and were grouped according to the occurrence of sepsis,the clinical characteristics and results of laboratory tests were collected from the patients.The subjects were brought into multivariate logistic regression a-nalysis after the primary screening with univariate regression analysis,the independent predictive factors were screened out,and the nomogram model was established.The accuracy,calibration accuracy and clinical practica-bility of the model were assessed by means of receiver operating characteristic(ROC)curves,calibration curves and decision curve analysis(DCA).RESULTS Among the 228 patients with ALF,159(69.74％)were diagnosed with sepsis.Totally 6 independent predictive factors were screened out by the multivariate analysis,including age[odd ratio(OR)=1.098,95％CI:1.030 to 1.220],aspartate transaminase(OR=0.998,95％CI:0.996 to 0.999),white blood cells counts(OR=1.037,95％CI:1.020 to 1.064),hemoglobulin(OR=0.981,95％CI:0.962 to 0.998),lactic acid(OR=1.187,95％CI:1.022 to 1.426)and mechanical ventilation(OR=3.463,95％CI:2.340 to 5.125).The area under the curve(AUC)of the nomogram model was 0.864(95％CI:0.807 to 0.921)in the training set,0.817(95％CI:0.717 to 0.918)in the validation set,remarkably better than that of sequential organ failure assessment(SOFA)scores[0.710(95％CI:0.625 to 0.795)and 0.647(95％CI:0.515 to 0.779)].Hosmer-Lemeshow test(P=0.512)and the calibrated curves showed that the predication probability of the model was highly consistent with the actual risk,and DC A indicated that the net clinical benefit was brought more from the model than from SOFA score.CONCLUSION The age,hemoglobulin,aspartate transaminase,white blood cells counts,lactic acid and mechanical ventilation are the independent predictive factors for the sepsis in the ALF patients.The nomogram model established based on the factors has high predictive efficiency and clini-cal application value.

Objective:To investigate the clinical characteristics and risk factors for recurrence of perianal abscess in children.Methods:A retrospective study was conducted on the clinical data of 161 children with perianal abscess who were hospitalized in the Children's Hospital affiliated to Zhengzhou University from January 2015 to December 2022.Based on whether or not recurrence occurred after treatment，the patients were divided into the recurrence group(58 cases) and the simple group(103 cases).The clinical manifestations，laboratory examination indexes，and recurrence risk factors of children with perianal abscess were analyzed.Results:The effective rate of treatment for 161 children with perianal abscess was 64.0% (103/161),and 58 cases had recurrent abscess or fistula formation.The main orientations of the lesions were at the 3 o'clock position in 62 cases (38.5%) and at the 9 o'clock position in 67 cases (41.6%) in the lithotomy site.Bacterial culture of drainage fluid from perianal abscesses was positive in 61 (37.9%) children and the pathogens were Klebsiella pneumoniae in 48 cases,Staphylococcus aureus in 7 cases and Escherichia coli in 6 cases.The recurrence group mainly had underlying diseases including 38 cases of Crohn's disease，15 cases of chronic diarrhoea，and 5 cases of immunodeficiency,while the simple group had 3 cases of Crohn's disease，36 cases of chronic diarrhoea，and 2 cases of immunodeficiency，with 62 cases（60.1%）had no underlying diseases.The recurrence group showed significant statistical differences in gender（ χ2= 4.347， P=0.041），age（ χ2= 4.071， P=0.045），abscess size（ χ2= 6.298， P=0.008），abscess with fistula（ χ2= 10.928， P<0.001），combined with underlying diseases（ χ2= 10.673， P<0.001），fever（ χ2= 6.215， P=0.014），growth retardation（ χ2= 8.273， P=0.004），malnutrition（ χ2=4.521， P=0.038），hospitalization cost（ t=5.581， P=0.021），and hospital stay（ t=5.309， P=0.036）compared to the simple group.Additionally，the recurrence group showed significant statistical differences in white blood cells（ t=6.873， P=0.006），C-reactive protein（ t=7.631， P=0.003），fecal calprotectin（ t=10.073， P<0.001），albumin（ t=4.587， P=0.025），interleukin-6（ t=11.648， P<0.001），tumor necrosis factor-α（ t=7.803， P=0.021），lymphocyte count（ t=8.478， P=0.011），CD4 +/CD8 + ratio（ t=10.674， P<0.001），and IgA（ t=6.437， P=0.002）compared to the simple group.Multivariate Logistic regression analysis showed that abscess with fistula，Crohn's disease，low IgA，low CD4 +/CD8 + ratio，and high fecal calprotectin were high risk factors for recurrence of perianal abscess in children. Conclusion:Children with perianal abscesses have a high recurrence rate and are prone to fistula formation.Perianal abscess with fistula，Crohn's disease，low IgA，low CD4 +/CD8 +ratio，and high fecal calprotectin are high risk factors for recurrence in children.

Purpose This study aims to explore the effect of peroxisomal membrane protein 4(PXMP4)on the migration and invasion of cervical cancer(CC)cells,as well as the epithelial-mesenchymal transition(EMT)process.Methods Bioinformatics and immunohistochemical analysis were employed to examine the expression of PXMP4 in CC tissues and its correlation with clinical pathological characteristics.Western blot and RT-qPCR were used to detect the expression of PXMP4 in CC cells.CCK-8 assay,scratch healing assay,and Transwell invasion assay were utilized to assess the proliferation,migration,and invasion capabilities of CC cells.Western blot was conducted to measure the expression of N-cadherin,E-cadherin,vimentin,phosphorylated ERK(p-ERK),and total ERK proteins in cervical CC.Results The TCGA database showed that the mRNA expression level of PXMP4 was significantly elevated in non-paired CC tissues(P=0.000 29),while the GEO database showed that the mRNA expression level of PXMP4 was sig-nificantly elevated in paired CC tissues(P=0.02).Immunohistochemical analysis showed that PXMP4 was primarily localized in the cytoplasm and cell membrane,with a positive rate of 70.31％(45/64)in CC tissues,significantly higher than 29.69％(19/64)in adjacent tissues.Clinical pathological analysis found that PXMP4 expression was as-sociated with maximum tumor differentiation(P=0.000 328)and lymph node metastasis(P=0.000 226),but not with age(P=0.637)or tumor diameter(P=0.304).CCK-8 assay,wound healing assay,and Transwell invasion as-say demonstrated that interference with PXMP4 inhibited the proliferation,invasion,and migration of CC cells,while overexpression of PXMP4 promoted these processes.Western blot results indicated that interference with PXMP4 signif-icantly increased E-cadherin expression and decreased N-cadherin,vimentin,and p-ERK expression(P＜0.05).Conversely,overexpression of PXMP4 led to a significant decrease in E-cadherin and an increase in N-cadherin,vim-entin,and p-ERK expression(P＜0.05).Additionally,stimulation of CC cells with different concentrations of the U0126 inhibitor significantly increased E-cadherin expression and decreased N-cadherin,vimentin,and p-ERK expres-sion(P＜0.05).Conclusion PXMP4 is highly expressed in CC tissues and is closely related to tumor differentiation and lymph node metastasis.PXMP4 promotes the EMT process of CC cells through the phosphorylated ERK1/2 signa-ling pathway.
