Objective To explore the clinical efficacy of plasma exchange (PE) and double-filtration plasmapheresis (DFPP) pretreatment regimens for high-titer ABO-incompatible kidney transplantation (ABOi-KT). Methods A retrospective analysis was conducted on 31 cases of ABOi-KT with a follow-up period ≥1 year admitted to Zhongshan Hospital Affiliated to Fudan University from April 2016 to August 2025. The efficacy differences between the PE combined with rituximab (RTX) + oral triple immunosuppressive regimen and the DFPP combined with RTX + oral triple immunosuppressive regimen were compared and analyzed. The titers of blood group antibodies and serum creatinine levels before and after the operation were monitored. The survival curves and cumulative risk occurrence curves were plotted using the Kaplan-Meier method. The survival rates of recipients and transplanted kidneys and the occurrence of complications were analyzed. Results Both the PE regimen and the DFPP regimen may effectively reduce the preoperative blood group antibody titer of the recipients to ≤1∶16. The one-year survival rate of the recipients and the transplanted kidneys both reached 100% after the operation. The postoperative serum creatinine levels of recipients who received the DFPP regimen were lower and more stable. There was no statistically significant difference in the incidence of complications between the two regimens during the same follow-up period. Conclusions Both the PE and DFPP regimens are effective pretreatment regimens for ABOi-KT. The DFPP regimen has more advantages in reducing treatment operations, lowering drug dosage and maintaining the stability of postoperative renal function. For recipients with a high initial antibody titer (≥ 1∶32), individualized determination of the number and frequency of plasma processing for pretreatment may achieve ideal therapeutic effects.

Objective: To explore the correlation between allogeneic red blood cell (RBC) transfusion and healthcare-associated infections (HAIs) in patients undergoing coronary artery bypass grafting (CABG) during the perioperative period. Methods: A single-center retrospective cohort of 1,170 patients undergoing isolated CABG was analyzed. Multivariable logistic regression and restricted cubic splines (RCS) were employed to explore the nonlinear association between perioperative RBC transfusion (from intraoperative period to 72 hours postoperatively) and HAIs. Results: Among the 1,170 CABG patients, 109 patients (9.2%) received RBC transfusion during the operation or within 3 days after the operation. The risk of HAIs in those who received ≥4 units of RBCs during and within 3 days after the operation was 6.89 times higher than that in the non-transfusion group (95% CI: 3.65-17.20). Furthermore, there was a nonlinear threshold effect between the blood transfusion volume and postoperative HAIs (inflection point: 7.8 units). When the transfusion volume was ≤7.8 units, the risk of HAIs increased by 61% for each additional unit transfused (OR=1.61, 95% CI: 1.21-2.15). Beyond this threshold, no statistically significant association was observed (P=0.289). Conclusion: Perioperative RBC transfusion in CABG patients is associated with an increased incidence of HAIs. The perioperative blood transfusion volume has a curvilinear relationship with the risk of postoperative HAIs. When the blood transfusion volume is ≤7.8 units, the blood transfusion volume has a dose-dependent relationship with postoperative infection, with higher blood transfusion volumes correlating with greater postoperative infection risk. When the blood transfusion volume is >7.8 units, the relationship between the two is not statistically significant. The preventive effect of reducing RBC transfusion on HAIs requires further validation in the future.

Invasive fungal infections (IFIs) have become prominent global health threats, escalating the burden on public health systems. The increasing occurrence of invasive fungal infections is due primarily to the extensive application of chemotherapy, immunosuppressive therapies, and broad-spectrum antifungal agents. At present, therapeutic practices utilize multiple categories of antifungal agents, such as azoles, polyenes, echinocandins, and pyrimidine analogs. Nevertheless, the clinical effectiveness of these treatments is progressively weakened by the emergence of drug resistance, thereby substantially restricting their therapeutic utility. Consequently, there is an imperative need to expedite the discovery of novel antifungal agents. This review seeks to present an exhaustive synthesis of novel antifungal drugs and candidate agents that are either under current clinical investigation or anticipated to progress into clinical evaluation. These emerging compounds exhibit unique benefits concerning their modes of action, antimicrobial spectra, and pharmacokinetic characteristics, potentially leading to improved therapeutic outcomes relative to conventional antifungal regimens. It is anticipated that these novel therapeutic agents will furnish innovative treatment modalities and enhance clinical outcomes in managing invasive fungal infections.

Objective To explore the correlation of neutrophil/lymphocyte ratio(NLR),monocyte/high density lipoprotein cholesterol ratio(MHR)and mild cognitive impairment(MCI)in patients with type 2 diabetes mellitus(T2DM).Methods 159 T2DM patients hospitalized in the Department of Endocrinology,Affiliated Hospital of Xuzhou Medical University from February 2023 to April 2023 were selected.The subjects were divided into normal cognitive function(Con,n=72)group and MCI group(n=87)based on score of Montreal cognitive assessment scale(MoCA).NLR and MHR were calculated and compared between the two groups.Spearman correlation analysis was used to analyze the correlation between NLR,MHR and MoCA score.Logistic regression analysis of the factors influencing the association between T2DM with MCI.Receiver operator characteristic(ROC)curve was used to evaluate the predictive value of NLR and MHR for DM complicated with MCI.Results Compared with Con group,MCI group showed a significant increase in hemoglobin A1c(HbA1c),fasting plasma glucose,NLR,MHR,neutrophil count,monocyte count,serum creatinine,cystatin C,while high density lipoprotein cholesterol lymphocytes,visual space and executive function,naming,attention,language ability,abstract thinking,delayed memory,orientation and MoCA score decreased(P＜0.05).Spearman correlation analysis showed that there was a negative correlation between MHR,NLR and MoCA score,visuospatial and executive function,delayed recall and attention.Logistic regression analysis showed that NLR,MHR,HbA1c were all risk factors for MCI in T2DM.ROC curve analysis showed that the area under the curve of NLR combined with MHR for diagnosing T2DM with MCI was 0.872,with corresponding sensitivity of 81.6%and specificity of 87.5%.Conclusions NLR and MHR are closely related to MCI in T2DM patients.The combination of NLR and MHR have certain efficacy in prediction T2DM with MCI.

Objective:To analyze the clinical characteristics and treatment outcomes of central nervous system（CNS）mucormycosis following allogeneic hematopoietic stem cell transplantation（allo-HSCT）.Methods:Clinical data of 6 patients diagnosed with CNS mucormycosis after allo-HSCT at Henan Cancer Hospital between January 2020 and December 2024 were retrospectively collected. The patients' clinical manifestations，laboratory findings，imaging features，treatment regimens，and outcomes were analyzed.Results:The incidence of CNS mucormycosis post-allo-HSCT was 0.7%（6/851）. The main clinical manifestations included impaired consciousness（5 cases），convulsions（3 cases），headache（2 cases），hemiplegia（1 case），ptosis（1 case），and mydriasis with sluggish light reflex and incomplete eye closure（1 case）. The median time from transplantation to the onset of neurological symptoms was 138 days（94-572 days）. Metagenomic next-generation sequencing（mNGS）of cerebrospinal fluid identified Rhizopus spp.（2 cases）， Rhizomucor spp.（2 cases），and Absidia spp.（2 cases）. Cranial MRI performed in five patients revealed multiple mass or patchy lesions in various regions；one patient underwent cranial CT，which showed patchy hypodense lesions in multiple areas. All patients received antifungal therapy，with 2 cases receiving combined intrathecal injection of amphotericin B liposomes；five patients died，and one survived. Conclusions:CNS mucormycosis is a rare but severe complication after allo-HSCT. Its clinical and radiological features are non-specific，posing diagnostic challenges. Intravenous administration of liposomal amphotericin B at full dosage，combined with intrathecal injection，may improve treatment efficacy.

A 20-year-old male patient with T-lymphoblastic lymphoma/leukemia received 9/10 human leukocyte antigen-compatible unrelated peripheral blood stem cell transplantation. He was transplanted with 5.91×10 8 mononuclear cells/kg and 2.88×10 6 CD34 + cells/kg, and neutrophil engraftment was obtained at +11 days and platelet engraftment at +9 days. After transplantation, he presented with repeatedly increased serum creatinine levels, BK virus (BKV) -associated hemorrhagic cystitis, and BKV viremia. BK virus nephropathy was diagnosed based on renal biopsy and metagenomic next-generation sequencing. After adjusting the immunosuppressant, intravenous immunoglobulin, and donor lymphocyte infusion treatment, the patient’s renal function deteriorated progressively, and he eventually died of multiple organ failure at +289 days.

Background and purpose:Esophageal carcinoma(ESCA)is one of the malignant tumors with high mortality rate,and the underlying mechanism of its development is largely unknown.CDC20 plays an important role in tumorigenesis,and its dysregulated expression is closely related to tumor occurrence and development.The expression of CDC20 is increased in a variety of tumors,and knocking down CDC20 can inhibit tumor cell proliferation.NLRP3 is the main component of the inflammasome,and inflammasome is also closely related to tumor occurrence and development.Here,our study aimed to investigate whether CDC20 promotes the proliferation of ESCA cells through NLRP3 and its regulatory mechanism.Methods:The expression levels of CDC20 and NLRP3 genes in ESCA patients were analyzed using The Cancer Genome Atlas(TCGA)detabase and GTEx public database.We collected clinical and pathological data and tissues from 80 ESCA patients at the First Affiliated Hospital of Xinxiang Medical College,and detected the protein expression of NLRP3 in ESCA patients through immunohistochemistry staining.This study was approved by the Ethics Committee of the First Affiliated Hospital of Xinxiang Medical College(Number:EC-021-137).We studied the effects of knocking down CDC20 and NLRP3 gene on the proliferation ability of esophageal squamous cell carcinoma cells EC9706 and KYSE150 using short hairpin RNA(shRNA)technology.Co-immunoprecipitation(Co-IP),proteasome inhibitors and ubiquitination experiments were used to detect whether CDC20 interacts with NLRP3,and to elucidate whether CDC20 regulates NLRP3 expression through the ubiquitination pathway.This study was approved by the Ethics Committee of the First Affiliated Hospital of Xinxiang Medical College(Number:EC-021-137).Results:The TCGA database analysis showed that the expression levels of CDC20 and NLRP3 mRNA were significantly higher in the cancer tissues of ESCA patients than in the adjacent tissues.The immunohistochemistry results further showed that compared with adjacent tissues,the protein expression levels of CDC20 and NLRP3 were increased in ESCA tissues.Knocking down CDC20 and NLRP3 genes inhibited the proliferation of ESCA cells.Co-IP,proteasome inhibitors and ubiquitination experiments confirmed that CDC20 interacted with NLRP3 through its leucine-rich repeat(LRR),and CDC20 stabilized its expression by promoting NLRP3 ubiquitination.Conclusion:CDC20 and NLRP3 are upregulated in ESCA tissues,and CDC20 stabilizes their expression through ubiquitination of NLRP3,promoting ESCA cell proliferation.This suggests that CDC20 and NLRP3 may be potential diagnostic targets for ESCA.
