BACKGROUND: The primary limitation to kidney transplantation is organ shortage. Recent progress in gene editing and immunosuppressive regimens has made xenotransplantation with porcine organs a possibility. However, evidence in pig-to-human xenotransplantation remains scarce, and antibody-mediated rejection (AMR) is a major obstacle to clinical applications of xenotransplantation. METHODS: We conducted a kidney xenotransplantation in a brain-dead human recipient using a porcine kidney with five gene edits (5GE) on March 25, 2024 at Xijing Hospital, China. Clinical-grade immunosuppressive regimens were employed, and the observation period lasted 22 days. We collected and analyzed the xenograft function, ultrasound findings, sequential protocol biopsies, and immune surveillance of the recipient during the observation. RESULTS: The combination of 5GE in the porcine kidney and clinical-grade immunosuppressive regimens prevented hyperacute rejection. The xenograft kidney underwent delayed graft function in the first week, but urine output increased later and the single xenograft kidney maintained electrolyte and pH homeostasis from postoperative day (POD) 12 to 19. We observed AMR at 24 h post-transplantation, due to the presence of pre-existing anti-porcine antibodies and cytotoxicity before transplantation; this AMR persisted throughout the observation period. Plasma exchange and intravenous immunoglobulin treatment mitigated the AMR. We observed activation of latent porcine cytomegalovirus toward the end of the study, which might have contributed to coagulation disorder in the recipient. CONCLUSIONS 5GE and clinical-grade immunosuppressive regimens were sufficient to prevent hyperacute rejection during pig-to-human kidney xenotransplantation. Pre-existing anti-porcine antibodies predisposed the xenograft to AMR. Plasma exchange and intravenous immunoglobulin were safe and effective in the treatment of AMR after kidney xenotransplantation.

Dendritic cells (DCs) serve as the primary antigen-presenting cells in autoimmune diseases, like rheumatoid arthritis (RA), and exhibit distinct signaling profiles due to antigenic diversity. Type II collagen (CII) has been recognized as an RA-specific antigen; however, little is known about CII-stimulated DCs, limiting the development of RA-specific therapeutic interventions. In this study, we show that CII-stimulated DCs display a preferential gene expression profile associated with migration, offering a new perspective for targeting DC migration in RA treatment. Then, saikosaponin D (SSD) was identified as a compound capable of blocking CII-induced DC migration and effectively ameliorating arthritis. Optineurin (OPTN) is further revealed as a potential SSD target, with Optn deletion impairing CII-pulsed DC migration without affecting maturation. Function analyses uncover that OPTN prevents the proteasomal transport and ubiquitin-dependent degradation of C-C chemokine receptor 7 (CCR7), a pivotal chemokine receptor in DC migration. Optn-deficient DCs exhibit reduced CCR7 expression, leading to slower migration in CII-surrounded environment, thus alleviating arthritis progression. Our findings underscore the significance of antigen-specific DC activation in RA and suggest OPTN is a crucial regulator of CII-specific DC migration. OPTN emerges as a promising drug target for RA, potentially offering significant value for the therapeutic management of RA.

The guidelines advocate for preoperative neoadjuvant radiotherapy and chemotherapy in cases of middle and low locally advanced rectal cancer. While some patients achieved pathological complete response (pCR), which is favorable and allows for potential organ preservation, treatment sensitivity varies and not all patients reach pCR. Identifying the factors influencing pCR is important for enhancing the effectiveness of neoadjuvant therapy and improving patient outcomes. Previous research has identified various factors associated with response to neoadjuvant therapy, which can serve as predictors of pCR. This study reviews recent literature on imaging, pathological, genetic, and molecular characteristics, laboratory indices, and therapeutic factors related to tumor response, both domestically and internationally. The aim is to summarize the latest advancements in understanding the factors associated with pCR in patients with locally advanced middle and low rectal cancer undergoing neoadjuvant therapy, thereby providing a theoretical foundation for standardized clinical treatment approaches.

Objectives:To observe the incidence of residual shunt post patent foramen ovale(PFO)closure and the effect of PFO closure in these migraine patients at one year after PFO. Methods:This retrospective study included patients who underwent PFO closure for migraine in the Second Affiliated Hospital Zhejiang University School of Medicine from January 2019 to June 2022,patients were divided into the grade 0 shunt group(n=67),the grade Ⅰ shunt group(n=10),the grade Ⅱ shunt group(n=13)and the grade Ⅲ shunt group(n=16)according to the results of contrast transthoracic echocardiography(cTTE)at 1 year after PFO closure.The incidence of postoperative migraine attacks among different groups of patients were compared.The risk factors of residual shunt after PFO closure were explored. Results:The mean age of enrolled 106 patients with migraine was(35.80±11.70)years,of which 83 patients(78.30%)were female.One year after PFO closure,the migraine attack and rating scale were significantly decreased compared to baseline in the grade 0 shunt group,in the grade Ⅰ shunt group and in the grade Ⅱ shunt group(all P<0.05),but not in the grade Ⅲ shunt group(P>0.05).The rate of significant and complete migraine was significantly higher in the grade 0 shunt group(58.21%),in the gradeⅠ shunt group(60.00%),in the grade Ⅱ shunt group(69.23%)as compared to the grade Ⅲ shunt group(18.75%,P=0.02)at one year after PFO.The rate of grade 0 shunt after PFO closure in patients with the microvesicles appearing in≥6 cardiac cycles in resting state before operation was significantly lower than in patients with the microvesicles appearing within 6 cardiac cycles and no microvesicles in resting state(24.00%vs.83.87%vs.70.00%,P=0.04).Logistic multivariate regression analysis showed that patients with microvesicles appearing beyond 6 cardiac cycles in resting state were more likely to have residual shunts in postoperative cTTE compared to the patients with negative cTTE and microvesicles appearing within 6 cardiac cycles in the cTTE in resting state before operation(OR=0.06,95%CI:0.02-0.23,P<0.01;OR=0.014,95%CI:0.05-0.41,P<0.01). Conclusions:Migraine patients who underwent PFO closure and with grade 0 to grade Ⅱ residual shunt at one year after PFO are most likely to have significant remission of migraine,while the incidence of migraine remission is low in patients with grade Ⅲresidual shunt.The incidence of residual shunt after PFO closure is higher in patients with the microvesicles appearing in 6 cardiac cycles in resting state in the cTTE before operation than in patients with the microvesicles appearing within 6 cardiac cycles and no microvesicles.

Objective To investigate the effect of staphylococcal nuclease and tudor domain containing 1(SND1)on the biological function of osteosarcoma cells and decipher the mechanism of SND1 in regulating fer-roptosis in osteosarcoma cells via SLC7A11.Methods Human osteoblasts hFOB1.19 and osteosarcoma cell lines Saos-2,U2OS,HOS,and 143B were cultured,in which the expression level of SND1 was determined.Small in-terfering RNA was employed to knock down the expression of SND1(si-SND1)in the osteosarcoma cell line HOS and 143B.The CCK8 assay kit,colony formation assay,and Transwell assay were employed to examine the effect of SND1 expression on the biological function of osteosarcoma cells.Furthermore,we altered the expression of SND1 and SLC7A11 in osteosarcoma cells to investigate the effect of SND1 on osteosarcoma ferroptosis via SLC7A11.Results The mRNA and protein levels of SND1 in Saos-2,U2OS,HOS,and 143B cells were higher than those in hFOB1.19 cells(all P<0.01).Compared with the control group,transfection with si-SND1 down-regulated the expression level of SND1 in HOS and 143B cells(all P<0.01),decreased the viability of HOS and 143B cells,reduced the number of colony formation,and inhibited cell invasion and migration(all P<0.001).The ferroptosis inducer Erastin promoted the apoptosis of HOS and 143B cells,while the ferroptosis inhibitor Fer-rostatin-1 improved the viability of HOS and 143B cells(all P<0.001).After SND-1 knockdown,Erastin reduced the viability of HOS and 143B cells,while Ferrostatin-1 restored the cell viability(all P<0.001).After treatment with Erastin in the si-SND1 group,the levels of iron and malondialdehyde were elevated,and the level of glutathione was lowered(all P<0.001).The results of in vivo experiments showed that SND1 knockdown inhibited the mass of the transplanted tumor in 143B tumor-bearing nude mice(P<0.001).Knocking down the expression of SND1 resul-ted in down-regulated SLC7A11 expression(all P<0.001)and increased ferroptosis in HOS and 143B cells(P<0.001,P=0.020).Conclusions SND1 presents up-regulated expression in osteosarcoma cells.It may inhibit ferrop-tosis by up-regulating the expression of SLC7A11,thereby improving the viability of osteosarcoma cells.

BACKGROUND: The effect of intra-operative chemotherapy (IOC) on the long-term survival of patients with colorectal cancer (CRC) remains unclear. In this study, we evaluated the independent effect of intra-operative infusion of 5-fluorouracil in combination with calcium folinate on the survival of CRC patients following radical resection. METHODS: 1820 patients were recruited, and 1263 received IOC and 557 did not. Clinical and demographic data were collected, including overall survival (OS), clinicopathological features, and treatment strategies. Risk factors for IOC-related deaths were identified using multivariate Cox proportional hazards models. A regression model was developed to analyze the independent effects of IOC. RESULTS: Proportional hazard regression analysis showed that IOC (hazard ratio [HR]=0.53, 95% confidence intervals [CI] [0.43, 0.65], P  < 0.001) was a protective factor for the survival of patients. The mean overall survival time in IOC group was 82.50 (95% CI [80.52, 84.49]) months, and 71.21 (95% CI [67.92, 74.50]) months in non-IOC group. The OS in IOC-treated patients were significantly higher than non-IOC-treated patients ( P  < 0.001, log-rank test). Further analysis revealed that IOC decreased the risk of death in patients with CRC in a non-adjusted model (HR=0.53, 95% CI [0.43, 0.65], P  < 0.001), model 2 (adjusted for age and gender, HR=0.52, 95% CI [0.43, 0.64], P  < 0.001), and model 3 (adjusted for all factors, 95% CI 0.71 [0.55, 0.90], P  = 0.006). The subgroup analysis showed that the HR for the effect of IOC on survival was lower in patients with stage II (HR = 0.46, 95% CI [0.31, 0.67]) or III disease (HR=0.59, 95% CI [0.45, 0.76]), regardless of pre-operative radiotherapy (HR=0.55, 95% CI [0.45, 0.68]) or pre-operative chemotherapy (HR=0.54, 95% CI [0.44, 0.66]). CONCLUSIONS: IOC is an independent factor that influences the survival of CRC patients. It improved the OS of patients with stages II and III CRC after radical surgery.

Objective:To investigate the impact of the clinicopathological characteristics of anorectal malignant melanoma (ARMM) on the prognosis.Methods:The clinicopathological data of 40 ARMM patients undergoing surgery at the Department of Colorectal Surgery, Cancer Hospital, Chinese Academy of Medical Sciences from Apr 2012 to Apr 2022 were collected, and the impact of different clinicopathological factors and treatment modalities on the overall survival of ARMM patients was investigated using Kaplan-Meier survival analysis and multifactorial Cox proportional risk model analysis.Results:Among 40 ARMM patients , 16 were male and 24 were female. The median age of onset was 61 yr. The median follow-up period for all patients was 47 (25-69) months, with a median survival of 19 (15-23) months and 1-year and 3-year survival rates of 74.3% and 21.7%, respectively. There was no statistically significant difference in survival time between the two groups of patients receiving wide local excision and abdominoperineal resection( χ2=1.281, P=0.258). Univariate analysis showed that overall survival in patients with ARMM was related to tumour diameter, depth of infiltration, specimen margin and lymph node metastasis ( χ2=1.281, P=0.039; χ2=3.760, P=0.042; χ2=6.581, P=0.010; χ2=21.683, P<0.001), and multivariate analysis suggested that lymph node metastasis was an independent risk factor for overall survival in patients with ARMM. Conclusion:Tumour diameter, depth of infiltration, specimen margin and lymph node metastasis were important prognostic influences in ARMM, and lymph node metastasis was an independent risk factor for overall survival in ARMM patients.
