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.

Lenvatinib, a second-generation multi-receptor tyrosine kinase inhibitor approved by the FDA for first-line treatment of advanced liver cancer, facing limitations due to drug resistance. Here, we applied a multidimensional, high-throughput screening platform comprising patient-derived resistant liver tumor cells (PDCs), organoids (PDOs), and xenografts (PDXs) to identify drug susceptibilities for conquering lenvatinib resistance in clinically relevant settings. Expansion and passaging of PDCs and PDOs from resistant patient liver tumors retained functional fidelity to lenvatinib treatment, expediting drug repurposing screens. Pharmacological screening identified romidepsin, YM155, apitolisib, NVP-TAE684 and dasatinib as potential antitumor agents in lenvatinib-resistant PDC and PDO models. Notably, romidepsin treatment enhanced antitumor response in syngeneic mouse models by triggering immunogenic tumor cell death and blocking the EGFR signaling pathway. A combination of romidepsin and immunotherapy achieved robust and synergistic antitumor effects against lenvatinib resistance in humanized immunocompetent PDX models. Collectively, our findings suggest that patient-derived liver cancer models effectively recapitulate lenvatinib resistance observed in clinical settings and expedite drug discovery for advanced liver cancer, providing a feasible multidimensional platform for personalized medicine.

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.

Systemic mastocytosis (SM) with RUNX1-RUNX1T1 positive acute myeloid leukemia (AML) is a rare myeloid tumor with no standard treatment. Two cases of SM patients with RUNX1-RUNX1T1 positive AML treated with sequential avapritinib after allogeneic hematopoietic stem cell transplantation (allo-HSCT) were reported in Henan Cancer Hospital. Mast cell in bone marrow disappeared, C-KIT mutation and RUNX1-RUNX1T1 fusion gene remained negative. Allo-HSCT sequential avapritinib is an effective treatment for SM patients with RUNX1-RUNX1T1 positive AML.

Objective:To investigate the efficacy and safety of avapritinib in the treatment of molecular biologically positive core binding factor-acute myeloid leukemia (CBF-AML) with KIT mutation after allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:We retrospectively analyzed the clinical data of six patients with molecular biologically positive CBF-AML with KIT mutation after allo-HSCT, who were treated with avapritinib at Henan Cancer Hospital from December 2021 to March 2023, and evaluated the efficacy and safety of avapritinib.Results:After 1 month of treatment with avapritinib, the transcription level of the fusion gene decreased in six patients, and the transcription level decreased by ≥1 log in five patients. In four patients who received avapritinib for ≥3 months, the fusion gene turned negative, and the median time to turn negative was 2.0 (range: 1.0-3.0) months. Up to the end of follow-up, four patients had no recurrence. The most common adverse reaction of avapritinib was myelosuppression, including neutropenia in two cases, thrombocytopenia in two cases, and anemia in one case. The non-hematological adverse reactions were nausea in two cases, edema in one case, and memory loss in one case, all of which were grades 1-2.Conclusion:Avapritinib was effective for molecular biologically positive CBF-AML patients with KIT mutation after allo-HSCT. The main adverse reaction was myelosuppression, which could generally be tolerated.

The kidneys are one of the main excretory organs for drugs and when drugs are not excreted effectively, they can accumulate in the kidneys or in the interstitial tubules, leading to drug-induced kidney injury. The tubulointerstitium accounts for 80% of the volume of the kidney and is the primary site of response to various types of renal injury. This article focuses on drug-induced acute interstitial nephritis, highlighting its clinical symptoms, listing common induction drugs, analysing pathological features, and explaining its pathogenesis from the perspective of immune response, with the aim of providing a basic and clinical evidence for subsequent studies.
