Objective:To evaluate the efficacy and safety of daratumumab in treating patients with monoclonal immunoglobulin deposition disease (MIDD) with renal injury.Methods:A case-series analysis study was conducted in MIDD patients with renal injury who received daratumumab treatment at the Department of Nephrology, Ruijin Hospital, affiliated to Shanghai Jiao Tong University School of Medicine, from December 2021 to October 2023. The clinical data of patients at the time of diagnosis and during the follow-up period were collected. Hematological and renal responses were assessed and adverse reaction events were recorded.Results:Seven patients diagnosed with MIDD were included in this study, with a male-to-female ratio of 5∶2 and age of 46 (43, 52) years. One patient was light-heavy chain deposition disease, and the remaining 6 patients were light chain deposition disease. Among them, 5 patients had received prior treatment (1-2 lines of treatment with the regimen of cyclophosphamide, bortezomib and dexamethasone), while 2 patients were newly treated, one of whom had already started hemodialysis at diagnosis. Prior to receiving monoclonal antibody treatment, difference of serum free light chain (dFLC) among the 7 patients was 52 (7, 295) mg/L. Excluding 1 patient on dialysis, the remaining 6 patients had 24-hour urinary protein of 1.1 (0.2, 4.7) g, serum creatinine of 178.5 (157.8, 279.8) μmol/L and estimated glomerular filtration rate of 33.9 (24.2, 41.1) ml·min -1·(1.73 m 2) -1. The daratumumab treatment was 17 (10, 20) infusions, with treatment duration of 17 (9, 23) months and follow-up time of 24 (13, 32) months. After treatment, among 5 previously treated patients, hematological response evaluation showed that 1 patient with baseline dFLC <20 mg/L and minimal residual disease negativity upon re-examination, while the remaining 4 patients achieved hematological responses of complete response or better. Renal response evaluation revealed that, except for 1 patient with partial response, the other 4 patients achieved very good partial response (VGPR) or better. Among 2 newly diagnosed patients, both achieved hematological efficacy at least VGPR, with one achieving renal complete response, while the other one remaining dialysis- dependent. Overall, dFLC of 7 patients was 4.9 (2.1, 11.5) mg/L. Among 6 non-dialysis patients, 24-hour urinary protein was 0.19 (0.06, 0.42) g, serum creatinine was 153.0 (120.8, 188.0) μmol/L and estimated glomerular filtration rate was 40.4 (35.2, 57.3) ml·min -1·(1.73 m 2) -1. No severe adverse reactions were observed during daratumumab treatment. Conclusion:The application of daratumumab in the treatment of MIDD with renal injury is effective and well tolerated, achieving high-quality hematological responses, with high renal responses reaching or exceeding VGPR and improvement of renal function.

OBJECTIVES:
To assess the preliminary efficacy and safety of a dose-intensified C5VD regimen (cisplatin, 5-fluorouracil, vincristine, and doxorubicin) in children with locally advanced hepatoblastoma.
METHODS:
This prospective study enrolled 24 children with newly diagnosed, locally advanced hepatoblastoma who received the dose-intensified C5VD regimen at Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine, and Shanghai Children's Hospital between January 2020 and December 2023. Clinical characteristics, treatment outcomes, and chemotherapy-related toxicities were analyzed.
RESULTS:
Of the 24 patients, 13 were male and 11 were female, with a median age at diagnosis of 18.7 months (range: 3.5-79.4 months). All patients achieved complete macroscopic resection of hepatic lesions without liver transplantation. Serum alpha-fetoprotein levels decreased significantly after two chemotherapy cycles. During a median follow-up of 38.4 months (range: 15.8-50.7 months), all patients maintained continuous complete remission, with 3-year event-free survival and overall survival rates of 100%. Across 144 chemotherapy cycles, the incidence rates of grade 3-4 neutropenia, thrombocytopenia, and infections were 97%, 77%, and 71%, respectively; no treatment-related deaths occurred. Notably, 5 patients (21%) developed Brock grade ≥3 hearing loss, of whom 1 required a hearing aid.
CONCLUSIONS
The dose-intensified C5VD regimen demonstrates significant efficacy with an overall favorable safety profile in the treatment of newly diagnosed, locally advanced pediatric hepatoblastoma. Grade 3-4 myelosuppression and infection are the predominant toxicities. However, high‑dose cisplatin-induced ototoxicity remains a concern, highlighting the need for improved otoprotective strategies.

This study aimed to provide scientific evidence for predicting quality markers(Q-markers) of Elephantopus scaber by establishing UPLC fingerprint of E. scaber from different geographical origins and determining the content of 13 major components, as well as conducting in vitro anti-cancer activity investigation of the main components. The chromatographic column used was Waters CORTECS UPLC C_(18)(2.1 mm×150 mm, 1.6 μm), and the mobile phase consisted of acetonitrile and 0.1% formic acid solution(gradient elution). The column temperature was set at 30 ℃, and the flow rate was 0.2 mL·min~(-1). The injection volume was 1 μL, and the detection wavelength was 240 nm. The UPLC fingerprint of E. scaber was fitted using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine(2012 edition) to determine common peaks, evaluate similarity, identify and determine the content of major components. The CCK-8 assay was used to explore the inhibitory effect of the main components on the proliferation of lung cancer cells. The results showed that in the established UPLC fingerprint of E. scaber, 35 common peaks were identified. Thirteen major components, including neochlorogenic acid(peak 1), chlorogenic acid(peak 2), cryptochlorogenic acid(peak 3), caffeic acid(peak 4), schaftoside(peak 6), galuteolin(peak 9), isochlorogenic acid B(peak 10), isochlorogenic acid A(peak 12), isochlorogenic acid C(peak 18), deoxyelephantopin(peak 28), isodeoxyelephantopin(peak 29), isoscabertopin(peak 31), and scabertopin(peak 32) were identified and quantified, and a quantitative analysis method was established. The results of the in vitro anti-cancer activity study showed that deoxyelephantopin, isodeoxyelephantopin, isoscabertopin, and scabertopin in E. scaber exhibited inhibition rates of lung cancer cell proliferation exceeding 80% at a concentration of 10 μmol·L~(-1), higher than the positive drug paclitaxel. These results indicate that the fingerprint of E. scaber is highly characteristic, and the quantitative analysis method is accurate and stable, providing references for the research on quality standards of E. scaber. Four sesquiterpene lactones in E. scaber show significant anti-cancer activity and can serve as Q-markers for E. scaber.

China is rich in antimony, boron, and vanadium mineral resources, which have been detected in environmental water bodies and drinking water. During the revision process of the "Standards for Drinking Water Quality (GB5749-2006)", research and evaluation are focused on three indicators: antimony, boron and vanadium. Vanadium is added and the limit value of boron is adjusted. This study reviews and discusses the technical contents related to the revision of the antimony, boron and vanadium, including the environmental presence levels, exposure status, health effects, and the revision of the standard limits of these three indicators. Suggestions are also made for the implementation of this standard.

To establish and identify induced pluripotent stem cells (iPSCs) derived from patients with Aicardi-Goutières syndrome (AGS) with TREX1 gene 667G>A mutation, and obtain a specific induced pluripotent stem cell model for Aicardi-Goutières syndrome (AGS-iPSCs). A 3-year-old male child with Aicardi-Goutieres syndrome was admitted to Zhongshan People's Hospital in December 2020. After obtaining the informed consent of the patient's family members, 5 ml peripheral blood samples from the patient were collected, and mononuclear cells were isolated. Then,the peripheral blood mononuclear cells(PBMCs) were transduced with OCT3/4, SOX2, c-Myc and Klf4 by using Sendai virus, and PBMCs were reprogrammed into iPSCs. The pluripotency and differentiation ability of the cells were identified by cellular morphological analysis, real-time PCR, alkaline phosphatase staining (AP), immunofluorescence, teratoma formation experiments in mice. The results showed that the induced pluripotent stem cell line of Aicardi-Goutieres syndrome was successfully constructed and showed typical embryonic stem-like morphology after stable passage, RT-PCR showed mRNA expression of stem cell markers, AP staining was positive, OCT4, SOX2, NANOG, SSEA4, TRA-1-81 and TRA-1-60 pluripotency marker proteins were strongly expressed. In vivo teratoma formation experiments showed that iPSCs differentiate into the ectoderm (neural tube like tissue), mesoderm (vascular wall tissue) and endoderm (glandular tissue). Karyotype analysis also confirmed that iPSCs still maintained the original karyotype (46, XY). In conclusion, induced pluripotent stem cell line for Aicardi-Goutières syndrome was successfully established using Sendai virus, which provided an important model platform for studying the pathogenesis of the disease and for drug screening.
