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.

Objective To explore the efficacy and safety of a zanubrutinib-based combination regimen as first-line treatment for patients with B-cell chronic lymphoproliferative disorder (B-CLPD). Methods A retrospective analysis was performed on 26 patients with B-CLPD, including indolent B-cell non-Hodgkin lymphoma (B-iNHL), mantle cell lymphoma (MCL), and other unclassifiable B-CLPD, who were newly diagnosed and treated at the Department of Hematology, Zhongshan Hospital (Xiamen), Fudan University between January 2021 and January 2025. Patients were divided into two groups according to the treatment regimen: BR (bendamustine plus rituximab) and ZBR (zanubrutinib combined with BR regimen). Baseline characteristics, treatment responses, and the incidence of treatment-related adverse events (TRAE) were compared between the two groups. Results No statistically significant differences in baseline characteristics were observed between the two groups. All patients completed at least four cycles of treatment. There were no significant differences between the BR and ZBR groups in partial response rate (46.2% vs 53.8%), complete response rate (53.8% vs 15.4%), overall response rate (100.0% vs 84.6%), or TRAE incidence. After the first cycle, the lymphocyte count was higher in the ZBR group than in the BR group (P=0.002); no other statistically significant differences in other hematologic parameters were observed at any treatment cycle. Conclusions In patients with B-iNHL, MCL, and other unclassifiable B-CLPD, the ZBR regimen demonstrates similar safety and response rates to the BR regimen. These findings support further investigation into the clinical value of ZBR as first-line treatment regimen in a limited course for indolent lymphoid malignancies.

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.

Diabetic kidney disease(DKD),a prevalent complication of diabetes mellitus,remains a leading cause of end-stage renal disease.Recent research has identified lipophagy,a novel mechanism in DKD pathogenesis,drawing increasing attention in the field.This paper explores the biological connotation of the"internal heat leading to Zheng"pathogenesis based on lipophagy.The study proposes that lipophagy represents the microscopic biological correlation of liver-spleen coordination in regulating spleen transport and the ascending-descending dynamics of the middle jiao.Under persistent hyperglycemia,the suppression of lipophagic activity mirrors the traditional Chinese medicine(TCM)pathophysiological process described as"excessive fire consuming healthy qi,"whereas aberrant lipid accumulation in the kidney corresponds to the dynamic aggregation and dispersion of micro-zhengjia.Lipotoxicity,a key driver of DKD progression,is interpreted as the biological manifestation of accumulated turbidity transforming into toxicity,resulting in progressive impairment of renal essence and function.The dynamic process of lipophagy dysfunction under hyperglycemia,marked by renal microangiopathy,glomerular and tubular dysfunction,and renal fibrosis,closely mirrors the pathological evolution of"micro-zhengjia"and"internal heat leading to Zheng."Consequently,TCM strategies for DKD prevention and treatment should emphasize heat regulation,stage-specific interventions,liver-spleen harmonization,metabolic modulation,early collateral protection,and blood-activating approaches.

Based on WANG Xugao's"thirty liver-regulating methods,"this paper summarized the clinical thinking of treating diabetic kidney disease from the liver.The liver is closely associated with the pathogenesis of diabetic kidney disease,including internal heat,essence depletion,latent wind,and the accumulation and dissipation of a conglomeration of kidney collateral zhengjia.WANG Xugao's"thirty liver-regulating methods"comprehensively reveals the physiological and pathological changes of the liver,as well as clinical approaches for liver treatment.Liver qi stagnation can lead to the generation of internal heat,liver stagnation and deficiency can cause essence depletion and collateral obstruction,and disharmony of the liver wood can cause internal wind disturbance,which all contribute to the progression of diabetic kidney disease at different stages.Treatment generally follows the essence of"thirty liver-regulating methods."In the early stage,treatment should focus on treating liver heat by soothing the liver qi,clearing the liver fire,and removing damp-heat to resolve stagnation and heat.In the middle stage,treatment should focus on treating liver deficiency by nourishing the liver yin to clear heat,replenishing the essence and blood to tonify deficiency,and promoting blood circulation to remove stasis,thereby strengthening the foundation and nurturing the primal essence.In the later stage,treatment should focus on treating liver wind to prevent complications and improve the patient's quality of life.Throughout the entire process,liver collaterals are treated using pungent herbs to invigorate qi and open the liver channels,relieving blood stasis and promoting circulation.In conjunction with the above methods,flexible selection of effective formulas and drug pairs should be used,each addressing specific treatment goals.

Objective:To investigate the feasibility of transcatheter edge-to-edge repair (TEER) using a short-clip strategy for patients with moderate-to-severe or greater degenerative mitral regurgitation caused by commissural prolapse.Methods:This retrospective study included patients with severe mitral regurgitation secondary to commissural prolapse who underwent TEER at the Second Affiliated Hospital of Zhejiang University School of Medicine between September 2022 and July 2024. Preoperative clinical and imaging data, intraoperative details, procedural outcomes, and 1-month postoperative follow-up results were collected.Results:A total of 19 patients were enrolled, aged (74.1±6.1) years, including 12 males. Among them, 10 patients had external commissural prolapse, and 9 patients had internal commissural prolapse. Preoperatively, all patients exhibited severe mitral regurgitation (4+), with an effective regurgitant orifice area of (0.55±0.17) cm2, left atrial volume of (104.77±36.57) ml, left ventricular end-diastolic volume of (102.29±32.47) ml, left ventricular end-diastolic dimension of (5.34±0.59) mm, and prolapse width of (1.18±0.34) cm. All procedures utilized short clips (NTR or NTW clips) to target the prolapsed commissural region and were completed successfully without intraoperative complications. At 1-month follow-up, no mortality, stroke, single-leaflet device attachment, myocardial infarction, or unplanned mitral reintervention occurred. Mitral regurgitation severity improved to ≤2+ in all patients, with left atrial volume of (74.49±33.83) ml, left ventricular end-diastolic volume of (85.90±18.05) ml, and left ventricular end-diastolic dimension of (4.93±0.37) mm (all P<0.05). Conclusion:The short-clip strategy, focusing on precise clip placement at the commissural interface, is feasible and effective for TEER in patients with severe mitral regurgitation due to commissural prolapse.
