ObjectiveTo analyze the risk factors for long-term cardiovascular events in patients undergoing long-term peritoneal dialysis （PD）， and to construct and validate a visual nomogram prediction model based on multiple parameters. MethodsA prospective cohort study was conducted， consecutively enrolling 248 maintenance PD patients （dialysis duration ≥ 3 months）. Demographic characteristics， clinical indicators， laboratory parameters， and echocardiographic indices （including left ventricular ejection fraction ［LVEF］， ratio of early diastolic mitral inflow velocity to early diastolic mitral annular velocity （E/e’）， etc.） were collected. The composite endpoint was defined as the occurrence of cardiovascular events or cardiovascular death， with non-cardiovascular death as the competing risk and loss to follow-up or the end of follow-up as censoring events. Fine-Gray competing risks model was used to screen independent predictors， based on which a nomogram model was constructed. Internal validation was performed using the Bootstrap method （1 000 resamplings）， and the concordance index （C-index） and time-dependent receiver operating characteristic （time-dependent ROC） curve were calculated to evaluate the model performance. ResultsWith a median follow-up of 29 months （interquartile range： 24–35 months）， 88 patients （35.48%） reached the composite endpoint， including 80 cases of cardiovascular events and 8 cases of cardiovascular death， and 4 patients died of non-cardiovascular causes. Multivariate Fine-Gray analysis revealed that age， diabetes mellitus， hemoglobin （HGB） level and E/e' ratio were independent influencing factors of the composite endpoint. Specifically， each 1-year increase in age was associated with a 3.0% increase in the risk of the composite endpoint （HR=1.030， P=0.006）； patients with diabetes mellitus had a 167.9% higher risk compared with non-diabetic patients （HR=2.679， P=0.007）； each 1g/L increase in HGB level contributed to a 1.5% reduction in the risk （HR=0.985， P=0.003）； and each 0.1 increase in E/e' ratio led to a 7.2% increase in the risk （HR=1.072， P=0.045）. The nomogram model had a C-index of 0.76 （95% CI： 0.698–0.820）， and the AUC of the time-dependent ROC curve reached 0.849 at 23 months of follow-up. ConclusionIncreased age， complicated with diabetes mellitus， decreased HGB， and elevated E/e' ratio are independent risk factors of long-term occurrence of cardiovascular events and cardiovascular death in patients undergoing long-term PD. The nomogram model constructed based on the above variables has good predictive value and clinical applicability， which can provide a reference for cardiovascular risk stratification and individualized intervention in long-term PD patients.

Organophosphate flame retardants (OPFRs) have been widely used as the main alternatives to bromine-based flame retardants, resulting in their widespread detection in environmental media and even in human blood. The potential health risks arising therefrom, particularly the direct impacts on the blood system, have become a focus in the field of environmental health. This article systematically reviewed the latest research progress on the hematotoxicity of OPFRs, covering three core aspects: the toxic effects aspect, which systematically elaborated on the bidirectional interference of OPFRs with coagulation function, their toxic effects on the hematopoietic system, and their disruptive effects on blood biochemical metabolism; the mechanistic analysis aspect, which dissected the multi-pathway, multi-target toxic mechanism network of OPFRs, including common pathways based on oxidative stress and inflammatory responses, the direct and indirect regulation of coagulation function mediated by nuclear receptors and endocrine disruption, and the disturbance of blood cell production at the source through disruption of the hematopoietic microenvironment; and the risk assessment aspect, which, in response to the limitations of traditional methods, focused on the application prospects and core advantages of novel approaches based on structure-activity relationships in filling data gaps and achieving precise risk prediction. This review aims to systematically summarize the research progress on the mechanisms of OPFR-induced hematotoxicity, providing systematic theoretical support for subsequent in-depth mechanistic studies, targeted epidemiological investigations, and the optimization of risk assessment models.

Background Shift work is increasingly common in modern industries as economic globalization continues to advance, and has been associated with type 2 diabetes mellitus (T2DM). Objective To investigate the independent and interactive effects of shift work types and physical labor intensity on the risk of T2DM within an occupational cohort of petroleum workers, aiming to provide a scientific basis for reducing the risk of T2DM among workers engaged in shift work and physical labor. Methods This cohort study enrolled petroleum workers who underwent occupational health examinations at Karamay Central Hospital in Xinjiang from 2013 to 2015. Using stratified sampling, employees aged 20–60 years who had been actively employed and had been working in their current positions for at least one year were selected. A total of 3720 participants completed the baseline questionnaire survey and health examination, and follow-up was conducted in 2023. T2DM was diagnosed according to the 2020 Chinese Guidelines for the Prevention and Treatment of Type 2 Diabetes. Shift work type was categorized into fixed day shift, two-shift rotation, three-team two-shift rotation, four-team three-shift rotation, and other shift schedules. Physical labor intensity was classified as light, moderate, heavy, and extremely heavy according to the Classification of Physical Labor Intensity for Petroleum Field Operations (SY/T 6358—2008). Poisson regression models were used to estimate the associations of shift work type, physical labor intensity, and their joint exposure categories with T2DM risk after adjustment for potential confounders. Results A total of 3473 participants completed follow-up. Poisson regression analysis showed that shift work type was associated with T2DM risk. After adjustment for confounders, compared with fixed day shift workers, those engaged in two-shift rotation, three-team two-shift rotation, four-team three-shift rotation, and other shift schedules had higher risks of T2DM, with RRs of 2.17 (95%CI: 1.44, 3.27), 1.86 (95%CI: 1.16, 2.97), 1.85 (95%CI: 1.17, 2.93), and 2.15 (95%CI: 1.20, 3.88), respectively. T2DM risk also differed across physical labor intensity groups, with the extremely heavy group showing the highest risk (RR=2.26, 95%CI: 1.44, 3.56), followed by the heavy group (RR=1.91, 95%CI: 1.29, 2.82). Compared with workers exposed to fixed day shift + light intensity, increased T2DM risks were observed in those exposed to fixed day shift + heavy intensity (RR=2.38, 95%CI: 1.16, 4.72) or extremely heavy intensity (RR=2.64, 95%CI: 1.13, 5.82); two-shift rotation + light (RR=2.71, 95%CI: 1.11, 6.14), moderate (RR=3.38, 95%CI: 1.43, 7.34), heavy (RR=3.61, 95%CI: 1.52, 7.84), or extremely heavy intensity (RR=4.93, 95%CI: 1.87, 11.12); three-shift two-team rotation + light (RR=2.75, 95%CI: 1.14, 6.19), moderate (RR=3.08, 95%CI: 1.14, 7.51), or heavy/extremely heavy intensity (RR=4.06, 95%CI: 1.77, 8.50); four-shift three-team rotation + heavy/extremely heavy intensity (RR=3.89, 95%CI: 1.78, 7.84); and other shift types + heavy/extremely heavy intensity (RR=4.57, 95%CI: 1.55, 11.30). Conclusion This study demonstrates that various types of shift work significantly increase the risk of T2DM, and that concurrent exposure to high physical labor intensity exacerbates this risk. Regular blood glucose monitoring and targeted health interventions are recommended for workers exposed to rotating shift schedules and high physical work intensity.

Objective:To summarize the initial experience of 5G-ultra-long-distance robotic hepatectomy.Methods:This is a retrospective case series study. The clinical information from 5 cases of 5G ultra-long-distance robot-assisted hepatectomy performed was collected from June 2023 to October 2024, in collaboration between Sir Run Run Shaw Hospital, Zhejiang University School of Medicine in Hangzhou and Alaer Hospital, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine in Alaer, located 4 600 km apart. The patients comprised 1 male and 4 females, aged from 36 to 59 years, with an average age of 48 years. Their body mass index ranged from 20.4 to 30.9 kg/m2, with an average of 24.62 kg/m2. Preoperatively, 5 patients were diagnosed with liver disease requiring hepatectomy. The operations used 5G ultra-remote four-arm endoscopic robot surgery system. The remote control room was located in Sir Run Run Shaw Hospital (Hangzhou, Zhejiang), and the robot operating room was located in Alaer Hospital (Alaer, Xinjiang). The wired network relied on 60 Mb/s high-speed public Internet special line (China Telecom). In order to ensure the security of data transmission, the system implemented a double-layer encryption strategy for the wired network, and carried out strict debugging and verification for both the wired and wireless networks. Perioperative data and information on network performance were collected for 5 patients.Results:The surgical duration of the 5 cases of 5G ultra-long-distance robot-assisted hepatectomy ranged from 49 to 342 minutes, with an average of 184 minutes. Intraoperative blood loss varied from 5 to 800 ml, averaging 183 ml. Network performance was evaluated during the surgery, revealing an average network latency of 108.2 ms, with no significant lag or delay observed during any of the procedures. All patients recovered smoothly, with a postoperative hospital stay ranging from 5 to 10 days, averaging 7.2 days. Postoperative complications included 1 case of hypoproteinemia and 1 case of pleural effusion. Pathological examination confirmed that all cases suffered benign liver diseases (three patients with hepatic hemangioma, one with regenerative nodule in cirrhosis, and one with hepatolithiasis and choledocholithiasis).Conclusion:The preliminary exploration of clinical practice indicated that 5G-ultra-long-distance robot-assisted surgery is feasible for hepatectomy, with no severe complications affecting patients′ recovery.

Objective:To explore the efficacy and its related factors of rituximab (RTX) in the treatment of children with frequently relapsing nephrotic syndrome/steroid-dependent nephrotic syndrome (FRNS/SDNS).Methods:It was a single-center retrospective study. The clinical data of FRNS/SDNS children first treated with RTX in the First Affiliated Hospital of Sun Yat-sen University from November 1, 2016 to September 1, 2023 were collected. The number of relapse within 1 year before and after RTX treatment, the time to first relapse after RTX treatment, and the time to B-cell reconstitution were analyzed. At the first treatment, a single dose of RTX was given at 375 mg/m 2, with a maximum dose of 500 mg, once a week, for 1 to 4 doses. The count of CD19 + lymphocytes in the peripheral blood of the children was continuously monitored. If B-cell reconstruction was performed, the decision on whether to proceed to the next course of RTX treatment was made based on clinical manifestations. Kaplan-Meier method was used to analyze relapse-free survival rate after receiving RTX. Cox proportional hazards regression model was used to analyze the related factors of relapse after RTX treatment. Results:A total of 98 FRNS/SDNS children receiving RTX treatment were enrolled, including 75 males (76.5%). The age at onset was 4.0 (1.9, 7.1) years and age of receiving RTX was 11.3 (8.5, 13.5) years. There were 90 children (91.8%) achieving complete remission, while 8 patients (8.2%) did not respond to RTX treatment, and 3 patients (3.1%) progressed to end-stage kidney disease after receiving RTX. The relapse-free survival rates at 6 months and 1 year after RTX treatment were 83.3% (75/90) and 57.9% (22/38), respectively. The frequency of relapse 1 year after RTX treatment decreased compared to 1 year before RTX treatment ( Z=-7.398, P<0.001). Compared with children without relapse during the period of B-cell depletion, relapsed children had a higher number of relapse within one year after RTX treatment ( Z=5.246, P<0.001). The time to first relapse after RTX treatment was 8.3 (4.6, 13.9) months in 51 relapse patients. Compared with children receiving 1 dose of RTX in the first course, those receiving 2 or more doses had a longer time to the first relapse ( Z=2.983, P=0.003). There was no statistically significant difference in time to the first relapse between children who received mycophenolate mofetil therapy after RTX treatment and those who didn't ( P>0.05). The reconstruction time of B cells after the first course of RTX was 6.9 (5.3, 9.0) months. Compared to children receiving one dose of RTX in the first course, those receiving two or more doses had a longer B-cell reconstitution time ( Z=2.739, P=0.006). There was no statistically significant difference in B-cell reconstitution time between children who received mycophenolate mofetil therapy after RTX treatment and those who didn't ( P>0.05). Univariate Cox regression analysis showed that recurrence after calcineurin inhibitor (CNI) treatment before RTX treatment and the number of recurrence in one year before RTX treatment were correlated factors of recurrence after RTX treatment (both P<0.05). Multivariate Cox regression analysis showed that recurrence after CNI treatment before RTX treatment was an independent correlated factor of relapse after RTX therapy ( HR=3.496, 95% CI 1.245-9.818, P=0.018). Infusion reactions occurred in 10 patients (10.2%) and infections were observed in 24 patients (24.5%) during B cell depletion. No serious adverse events occurred. Conclusions:RTX is well tolerated and effective in treating FRNS/SDNS. Recurrence after CNI treatment before RTX treatment may be an independent related factor of relapse after RTX treatment.

Colorectal cancer(CRC)is a prevalent malignancy of the digestive tract in China;it exhibits aggressive progression that is closely associated with tumor microenvironment(TME)modulation.Tumor-associated macrophages,which are pivotal immunomodulatory com-ponents of the TME,demonstrate remarkable functional heterogeneity.Among these,secreted phosphoprotein 1-positive tumor-associated macrophages(SPP1+TAMs)represent a distinct subset with well-characterized protumorigenic properties.Evidence indicates that SPP1+TAMs exhibit a unique spatial distribution pattern in CRC tissues,with pronounced enrichment at the invasive tumor front and metastatic niches.Through the secretion of SPP1 and other effector molecules,this subset orchestrates multifaceted oncogenic processes,including tumor cell adhesion,migration,angiogenesis,and metastatic dissemination.This review systematically elucidates the spatial distribution,molecular reg-ulatory mechanisms,and clinical implications of SPP1+TAMs in CRC,thereby providing a theoretical foundation for developingnovel diagnost-ic biomarkers and targeted therapeutic strategies.

Objective To investigate the therapeutic effect and potential mechanisms of allogeneic renal subcapsular transplantation of CD24+renal epithelial cells for the treatment of acute kidney injury(AKI)induced by ischemia-reperfusion(I/R).Methods CD24+renal epithelial cells were isolated from mouse kidneys using flow cytometric sorting and expanded by passaging.C57BL/6N mice were randomly divided into three groups:the normal control group(n=8,sham surgery only),the model control group(n=8,unilateral kidney I/R plus contralateral nephrectomy),and the CD24+cell treatment group(n=8,AKI model followed by renal subcapsular transplantation of CD24+cells).Mice were euthanized at 24 h after modeling and serum was collected to measure biochemical markers[serum creatinine(Scr),blood urea nitrogen(BUN),tumor necrosis factor-α(TNF-α),and interleukin-6(IL-6)].Renal tissues were subjected to pathological evaluation and macrophage staining.An M1-polarized macrophage model was established using mouse bone marrow-derived macrophages co-cultured with CD24+renal epithelial cells.The polarization state of macrophages was assessed by quantitative real-time polymerase chain reaction(qPCR)and flow cytometry.Results CD24+renal epithelial cells were successfully isolated and passaged stably.Compared with the normal control group,the model control group exhibited significantly elevated Scr and BUN levels and renal pathological damage.In contrast,the CD24+cell treatment group showed significant reduction in serum biochemical markers and pathological injury compared with the model control group,along with reduction in M1 macrophage infiltration in the kidneys(P<0.05,P<0.01).In vitro co-culture experiments demonstrated that in the CD24+co-culture group,the expression of M1 polarization-related markers in macrophages was significantly lower than that in the non-co-culture group,and the proportion of CD80+M1 macrophages in the co-culture group decreased(P<0.05,P<0.01).Conclusion Allogeneic renal subcapsular transplantation of CD24+renal epithelial cells can alleviate I/R-induced AKI by inhibiting M1 macrophage polarization through paracrine mechanisms.
