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.

OBJECTIVE:
To observe the clinical efficacy of wrist-ankle acupuncture in the treatment of functional frequent premature ventricular contractions (PVCs).
METHODS:
A total of 64 patients with functional frequent PVCs were randomly divided into an observation group and a control group, 32 cases in each group. The observation group was treated with wrist-ankle acupuncture at bilateral upper 1 and upper 2 on the wrist. The control group received sham acupuncture at the same points as the observation group. Both groups were treated once every day from Monday to Friday, with the needles retained for 60 min each time, for a total of 4 weeks. The TCM syndrome score, the 24-hour PVC count, and MOS 36-item short form health survey (SF-36) score were compared between the two groups before and after treatment, and the clinical efficacy was evaluated after treatment.
RESULTS:
After treatment, the TCM syndrome scores and the 24-hour PVC counts in both groups were reduced compared with those before treatment (P<0.01), and the above indexes in the observation group were lower than those in the control group (P<0.01). After treatment,scores of all SF-36 items in the observation group were increased compared with those before treatment (P<0.01); in the control group, the scores of general health (GH), social function (SF) and role-emotional (RE) were increased compared with those before treatment (P<0.05). After treatment, scores of all SF-36 items in the observation group were higher than those in the control group (P<0.01). The total effective rate in the observation group was 90.6% (29/32), which was higher than 46.9% (15/32) in the control group (P<0.01).
CONCLUSION
Wrist-ankle acupuncture has a significant clinical efficacy in the treatment of functional frequent PVCs. It can effectively improve symptoms such as chest tightness and palpitations, reduce 24-hour PVC count, and improve patients' quality of life.

Objective:
To study the effect of metformin sensitizing pancreatic cancer cells with radiotherapy, with a focus on elucidating the underlying mechanisms of radiotherapy resistance. In particular, the role of the PERK/P-eIF2/ATF4 signaling pathway in mediating these effects was preliminarily explored.
Methods :
Pancreatic cancer cell lines(PANC-1 and PANC-2) were categorized into control, radiotherapy, and drug treatment groups. Following the respective treatments, cell proliferation inhibition was assessed using the CCK-8 assay, colony formation assays, and cell death staining. Senescence was quantified by β-galactosidase(SA-β-Gal) staining. The expression of cell cycle regulators(P21, P16, γ-H2AX), apoptosis markers(Bax, Bcl-2, Cleaved caspase-3), and pathway-related proteins(PERK, P-eIF2, ATF4) was evaluated by Western blot and immunofluorescence. To further investigate the role of the PERK/P-eIF2/ATF4 axis in metformin-mediated modulation of pancreatic cancer cell senescence and radiosensitization, selective inhibitors(GSK2606414) and agonists(MK-28) of PERK were employed.
Results :
Radiotherapy markedly upregulated senescence-associated markers(P21, P16, γ-H2AX, and β-galactosidase activity) in pancreatic cancer cells. Senescent cells exhibited enhanced proliferative activity and increased tumor volume both in vitro and in vivo. Metformin mitigated radiotherapy-induced senescence by reducing the expression of senescence markers and significantly suppressing the clonogenic and proliferative capacity of treated cells. Mechanistically, radiotherapy activated the PERK signaling pathway, leading to increased expression of PERK, P-eIF2, and ATF4, thereby driving cellular senescence. Pharmacological inhibition of PERK reduced β-galactosidase activity, while PERK activation further promoted the expression of senescence-associated proteins—an effect that was reversed by metformin.
Conclusion
Metformin inhibits the activation of the PERK/P-eIF2/ATF4 signaling pathway in pancreatic cancer cells following radiotherapy, thereby delaying cellular senescence and reducing the associated radiotherapy resistance of senescent cells. This modulation contributes to the sensitization of pancreatic cancer cells to radiotherapy.

Diabetic kidney disease (DKD) is a common microvascular complication of diabetes. "Internal heat leading to zheng" is the core pathogenesis of DKD, while "glucose toxicity" is transformed from subtle substances through "internal heat" and the cementation of various pathological products, which is pivotal to the transformation of diabetes to DKD. "Glucose toxicity" is characterized by deep and widespread heat, caused by various pathological factors, and its sticky nature makes it difficult to resolve, which can cause severe damage to the kidney collaterals. In the early stage of "glucose toxicity", it is yang pathogen, which can be transformed into yin pathogen in the later stage with disease progression. In clinical practice, treatment should be based on disease staging, with attention on grasping the pathogenesis of "internal heat leading to zheng" and identifying the nature of "glucose toxicity". During the diabetic period, clearing heat is the primary method, often using modified Yueju Pill and Dachaihu Decoction. In the early stage of DKD, treatment primarily focuses on clearing and penetrating latent heat to treat DKD, aiming to prevent toxic heat from transitioning from qi to blood. The approach emphasizes clearing heat and re-penetrating, detoxification, and re-clearing, often using a self-made modified Qingre Xiaozheng Decoction. In the middle and late stages of DKD, the focus shifts to clearing heat, eliminating zheng, strengthening vital qi, and dispelling turbidity, with commonly used treatments including the self-made modified Xiezhuo Xiaozheng Formula, Jingui Shenqi Pill, and Zhenwu Decoction.
