Objective To analyze the characteristics of adverse drug reactions （ADR） reported in Sixth People’s Hospital South Campus, Shanghai Jiaotong University from 2021 to 2023, to provide reference for promoting rational clinical drug use. Methods ADR data reported in our hospital were collected retrospectively, including patients’ basic information, drugs causing adverse reactions, types of adverse reactions and outcomes. Descriptive analysis methods were used to summarize and analyze the data. Results A total of 979 cases of ADR were reported in our hospital from 2021 to 2023. The highest proportion of patients with ADR occurred in the age range of 31 to 50, and more male patients （63.5%）. The top five drugs involved with adverse reactions were antibiotics （48.8%）, Chinese medicine injections（19.2%）, vitamins（7.5%）, Chinese traditional medicine（7.2%）, equine tetanus immunoglobulin（6.3%）. Among antibiotics, cefuroxime, ceftazidime and cefotiam were the majority. The organs/systems involved in all ADR were mainly skin and accessories damage （55.4%）. The clinical manifestations were rash, itching, and maculopapular rash. Conclusion From 2021 to 2023, the most common drugs causing adverse drug reactions in our hospital were mainly antibacterial drugs, and the rational clinical use of antibacterial drugs still needs to be concerned.

Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.

Osteoporosis is a common bone disease， whose incidence is still on the rise， posing great challenges to patients and society. This review mainly studies the pathogenesis of osteoporosis from the aspects of oxidative stress， inflammatory response， and glucolipotoxicity-induced injury and clarifies the efficacy and mechanism of some active ingredients of traditional Chinese medicine against osteoporosis through the integration of in vitro and in vivo experiments. The experimental results suggest that some active ingredients can improve bone resorption markers and maintain bone homeostasis by modulating inflammation， oxidative stress， etc. These active ingredients regulate osteoporosis through the receptor activator of nuclear transcription factor-κB （NF-κB） ligand （RANKL） pathway， osteoprotegerin （OPG） pathway， Wnt/β-catenin pathway， NF-κB pathway， mitogen-activated protein kinase （MAPK） pathway， adenosine monophosphate （AMP）-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway， and oxidative stress pathway. This review provides ideas for the progress of the prevention and treatment of osteoporosis with the active ingredients of traditional Chinese medicine， aiming to provide new potential lead compounds and reference for the development of innovative drugs and clinical therapy for the treatment of osteoporosis.

Assessment is an indispensable and critical activity in the educational process. In the recent decades, with the birth and development of competence-based educational paradigm, the rationale behind assessment is shifting from "assessment of learning" to "assessment for learning". Workplace-based assessment (WPBA), which aims to improve the quality of both learning and teaching through assessment in real workplace circumstances, is a set of assessment tools that conforms to the new concepts of medical education. In this article, with the purpose to promote the application of WPBA and thus enhance the quality of dental education in our country, a thorough discussion is performed regarding the core principles, tools, advantages of WPBA as well as attentions that should be noted when applying WPBA. It is recommended to establish a longitudinal assessment system which employs various WPBA tools and assesses the development of students' competencies through the whole educational process. Such a dynamic assessment system may be helpful to provide all-rounded and competent dental talents who can eventually benefit the society.

In order to meet the needs of the comprehensive development of life sciences and medicine,and fulfill the coher-ence and intersectionality of undergraduate experimental courses,it is necessary to break the teaching contents of conventional single experiment courses,and carry out the teaching reform of tumor comprehensive experimental course.Molecular biology and immuno-logy are two basic subjects which are closely related to the scientific research of life science,basic medicine and clinical medicine.Meantime,they are important sources for students to acquire skill training and scientific thinking as well.In this study,we try to inte-grate the experimental courses about the analysis and intervention of tumor-related genes based on the molecular biology and immunology technologies,facilitating to establish a new tumor comprehensive experimental course system.The course focuses on the development of students'logical thinking,and simulates the scientific research process through database screening,experimental operation,experi-mental report and paper writing,so as to significantly improve undergraduates'interest in scientific research and their ability to com-bine theory with practice,and cultivate students'rigorous scientific and innovative thinking ability as well as their ability to compre-hensively analyze and solve problems.It lays a solid foundation for future postgraduate related scientific research.At the same time,it is helpful to train teachers with multi-disciplinary knowledge reserves,and promote the coordinated development of scientific research through teaching.

Diabetes mellitus is a metabolic disease with high incidence and many complications,among which type 2 diabetes mellitus(T2DM)accounts for a large proportion.Current studies have shown that T2DM is accompanied by damage of liver,kidney,and other organs and its complications seriously en-danger human health.Ferroptosis generates many Reactive Oxygen Species(ROS)through the Fenton reaction,and the accumulation of ROS activates Hypoxia Inducible Factor-1(HIF-1α).As a result,the level of vascular endothelial growth factor(VEGF)is increased.Ferrostatin-1(Fer-1),a ferroptosis in-hibitor,has strong antioxidant capacity.Therefore,based on the hypoxia-inducible factor-1α/vascular endothelial growth factor(HIF-1α/VEGF)signaling pathway,we explored the therapeutic effect of Fer-1 on the liver and kidney tissues of diabetic mice.db/db mice(21～22 weeks old)were used as the model of diabetes mellitus.Ferroptosis inhibitor Fer-1 was used as the intervention drug.db/m mice served as the blank control group,and body weight and blood glucose were measured for 4 weeks.Food intake and water intake were recorded in each group.The levels of Alanine aminotransferase(ALT)and Aspartate aminotransferase(AST)in the serum were measured.ROS and Glutathione(GSH)activity in liver and kidney tissues and urinary protein content were measured.Liver and kidney tissue sections were stained with Hematoxylin-Eosin(HE),and the pathological morphology was observed under a light microscope.The protein levels of HIF-1α,VEGF,and glutathione peroxidase 4(GPX4)in liver and kidney tissues were detected by Western blot.In db/db mice,Fer-1(1 mg·kg-1,ig)could significantly reduce the a-mount of food and water intake,the levels of ALT and AST in serum,the ROS production in liver and kidney tissues,and the level of urine protein,but significantly increase the activity of GSH,thus improve the pathological conditions of liver and kidney.Fer-1 also significantly inhibited HIF-1α and VEGF pro-tein indexes and increased GPX4 protein levels in liver and kidney tissues.Although Fer-1 can not change the body weight and reduce blood glucose in diabetic mice,it can play a therapeutic role in the liver and kidney tissues of diabetic mice in the middle and late stages,and its mechanism may be related to HIF-1α/VEGF and GPX4.

In mass spectrometry-based proteomics experiments,achieving high-throughput and efficientproteolytic digestion is crucial to ensure optimal protein cleavage and enhance the depth of protein identi-fication (including the number of identified proteins and the coverage of protein amino acid sequences) .Trypsin is the most widely used protease in mass spectrometry-based proteomics due to its ability to spe-cifically cleave the carboxyl terminus of arginine and lysine.However,it was found that Trypsin has some missed enzymatic efficiency for the cleavage of lysine residues.Therefore,in actual proteomics sample preparation,a combination of Trypsin and LysC will be used to ensure adequate cleavage of lysine resi-dues.Our study revealed that the commonly employed LysC-Trypsin tandem cleavage method exerts an impact on the enzymatic cleavage of protein samples by Trypsin due to the subsequent cleavage of Trypsin by initially added LysC.Consequently,we adjusted the order of LysC and Trypsin tandem digestion,with Trypsin cleavage being performed first followed by the addition of LysC to target any missed lysine resi-dues.We comprehensively compared and analyzed three distinct sequential digestion methods,namely Trypsin-Trypsin (T-T),LysC-Trypsin (L-T),and Trypsin-LysC (T-L),in terms of their effects on pro-tein sample preparation quality.The results demonstrated that the Trypsin-LysC sequential digestion ap-proach not only minimizes missed protein lysine/arginine cleavage sites without increasing experimental costs,at the same time yielding peptides with a moderate amino acid sequence length.The use of Tryp-sin-LysC digestion enhances the adsorption and separation of peptide samples in RP-HPLC,as well as improves the depth of protein detection and amino acid sequence coverage during tandem mass spectrome-try analysis.This research work offers a novel technical solution and serves as a valuable reference for proteome sample preparation.

Objective:To study the incidence and risk factors of herpes zoster in patients with multiple myeloma and to evaluate the preventive effect of antiviral therapy.Methods:The clinical features of multiple myeloma patients with herpes zoster were retrospectively analyzed,the risk factors of herpes zoster and the effect of antiviral prophylaxis were analyzed.Results:Among 180 patients with multiple myeloma,23 cases developed herpes zoster(12.8％).The incidence of herpes zoster was 19.1％in patients with renal dysfunction and 23.5％after autologous hematopoietic stem cell transplantation(ASCT).The incidence of herpes zoster was higher in patients receiving bortezomib-containing regimens(21/137,15.3％)than that in those without bortezomib(2/43,4.7％),but there was no statistical difference(P=0.067).Antiviral prophylaxis was associated with fewer zoster infections,8/111(7.2％)developed herpes zoster in patients who received antiviral prophylaxis,and 15/69(21.7％)in those receiving no prophylaxis(P=0.005).65.2％of patients with herpes zoster did not receive antiviral prophylaxis.Multivariate analysis showed that bortezomib treatment,AHSCT and renal dysfunction were independent risk factors for multiple myeloma with herpes zoster,while antiviral prophylaxis was independently associated with reducing the risk of herpes zoster.Herpes zoster had no effect on OS in patients with multiple myeloma.Conclusion:The risk of herpes zoster in multiple myeloma patients was increased.Antiviral prophylaxis can reduce the risk of herpes zoster in patients on bortezomib-based therapy.

Objective:To investigate the safety and efficacy of mitoxantrone liposome in the treatment of children with high-risk acute myeloid leukemia(AML).Methods:The children with high-risk AML who received the mitoxantrone liposome regimen at Wuhan Children's Hospital from January 2022 to February 2023 were collected as the observation group,and the children with high-risk AML who received idarubicin regimen were enrolled as controls,and their clinical data were analyzed.Time to bone marrow recovery,the complete remission rate of bone marrow cytology,the clearance rate of minimal residual disease,and treatment-related adverse reactions were compared between the two groups.Results:The patients treated with mitoxantrone liposome showed shorter time to recovery of leukocytes(17 vs 21 day),granulocytes(18 vs 24 day),platelets(17 vs 24 day),and hemoglobin(20 vs 26 day)compared with those treated with idarubicin,there were statistical differences(P＜0.05).The effective rate and MRD turning negative rate in the observation group were 90.9％and 72.7％,respectively,while those in the control group were 94.1％and 76.4％,with no statistical difference(P＞0.05).The overall response rate of the two groups of patients was similar.Conclusion:The efficacy of mitoxantrone liposome is not inferior to that of idarubicin in children with high-risk AML,but mitoxantrone liposome allows a significantly shorter duration of bone marrow suppression and the safety is better.

Objective:To investigate the prognostic value of minimal residual disease(MRD)detected by multi-parameter flow cytometry(MFC)in pediatric patients with acute myeloid leukemia(AML)after induction chemotherapy.Methods:A retrospective study was conducted on 97 pediatric patients initially diagnosed with AML at Wuhan Children's Hospital from August 2015 to December 2022.The study analyzed the results of MRD detection using MFC after the first and second cycles of induction chemotherapy,and its association with prognosis were analyzed.Results:Following the first cycle of induction treatment,57 of the 97 patients tested positive for MRD(MRD1+,58.8％).Subsequently,19 patients remained MRD positive(MRD2+,19.6％)after the second cycle of induction treatment.Kaplan-Meier survival analysis showed that the estimated 3-year overall survival(OS)rate of the 37(64.9％)MRD1+patients who underwent transplantation was significantly higher than that of the 20(35.1％)MRD1+patients who did not undergo transplantation(84.6％vs 40.0％,P=0.0001).Among the 35 MRD1+MRD2-patients,the 3-year OS rate of the 25 children who underwent transplantation was higher than that of the 10 children who did not undergo transplantation(87.2％vs 70.0％,P=0.3229).The 3-year OS rate of the 19 MRD1+MRD2+patients was lower than that of the 35 MRD1+MRD2-patients(57.4％vs 81.8％,P=0.059).In the 19 MRD2+patients,the 3-year OS rate of the 12 children who underwent transplantation was significantly higher than that of the 7 children who did not undergo transplantation(80.8％vs 14.3％,P=0.0007).There was no significant difference in 3-year OS between the 12 MRD1+MRD2+patients and 25 MRD1+MRD2-patients,both treated with transplantation(80.8％vs 87.2％,P=0.8868).In those not treated with transplantation,the 7 MRD1+MRD2+patients had a significantly lower 3-year OS compared with the 10 MRD1+MRD2-patients(14.3％vs 70.7％,P=0.0114).Further multivariate analysis indicated that MRD2 positivity and transplantation were both independent prognostic factors(P=0.031,0.000),while MRD1 positivity was not significantly associated with the overall prognosis of 97 patients(P=0.902).Conclusion:MRD positivity following the second cycle of induction chemotherapy is an independent risk factor for unfavorable outcomes in children with AML.MRD2 positivity indicates a poorer prognosis and can help to identify the candidates requiring transplantation.MRD2 positivity is not a contraindication for transplantation in pediatric patients,and early transplantation significantly improves the prognosis of high-risk patients.
