Objective:To screen m6A modification-related genes, and to establish a prognostic model in patients with FLT3 mutated acute myeloid leukemia(AML), especially in older patients and to evaluate the prognostic efficiency of the model.Methods:Gene expression omnibus(GEO)datasets were used to analyze abnormally expressed m6A enzymes and reading proteins in FLT3 mutated AML; Correlation analysis was used to screen m6A modified-related genes in expression profiles.By integrating TCGA and BEAT data, 83 FLT3 mutated AML patients were included, and 32 of them were older than 60 years.Univariate Cox analysis and Lasso regression were conducted to construct the risk model.Kaplan-Meier curve and time-dependent receiver operating characteristic curve(tROC)were used to evaluate the prognostic efficiency of the model; subgroup analysis was conducted in the older patients.The concordance index(C-index)and calibration curve were used to evaluate the discrimination and accuracy of the model.Results:14 m6A modification enzymes or reading proteins were abnormally expressed in patients with FLT3 mutated AML.Correlation analysis filtered out 2 476 m6A related genes in expression profile.In TCGA and BEAT integrated data, univariate Cox analysis identified 132 prognostic genes.Lasso regression selected seven candidate genes to establish the prognostic risk model, including AKAP9, AVEN, DMCA1, DPYD, FAR2, GPHN and SPECC1L.Kaplan-Meier curve showed that high-risk group of the model had significantly shorter overall survival with a hazard ratio( HR)of 5.08(95% CI: 2.54-10.14, P<0.001).The area under the curve(AUC)in tROC for 1-year survival was 0.83; the C-index of risk model was 0.737.In older patients, the hazard ratio( HR)of the risk model for 1-year overall survival was 3.40(95% CI: 1.25-9.24, P=0.017)with an AUC of 0.79. Conclusions:The risk model based on m6A modified-related genes has some predictive value in assessing the prognosis of patients with FLT3 mutated AML, especially indicative to prognosis prediction in the elderly.

The tumor microenvironment,particularly the hypoxic property and glutathione(GSH)overexpression,substantially inhibits the efficacy of cancer therapy.In this article,we present the design of a magnetic nanoplatform(MNPT)comprised of a photosensitizer(Ce6)and an iron oxide(Fe3O4)/manganese oxide(MnO2)composite nanozyme.Reactive oxygen species(ROS),such as singlet oxygen(1O2)radicals produced by light irradiation and hydroxyl radicals(·OH)produced by catalysis,are therapeutic species.These therapeutic substances stimulate cell apoptosis by increasing oxidative stress.This apoptosis then triggers the immunological response,which combines photodynamic therapy and T-cell-mediated immunotherapy to treat cancer.Furthermore,MNPT can be utilized as a contrast agent in magnetic resonance and fluorescence dual-modality imaging to give real-time tracking and feedback on treatment.

Decellularized matrix transplantation has emerged as a promising therapeutic approach for repairing tissue defects, with numerous studies assessing its safety and efficacy in both animal models and clinical settings. The host immune response elicited by decellularized matrix grafts of natural biological origin plays a crucial role in determining the success of tissue repair, influenced by matrix heterogeneity and the inflammatory microenvironment of the wound. However, the specific immunologic mechanisms underlying the interaction between decellularized matrix grafts and the host immune system remain elusive. This article reviews the sources of decellularized matrices, available decellularization techniques, and residual immunogenic components. It focuses on the host immune response following decellularized matrix transplantation, with emphasis on the key mechanisms of Toll-like receptor, T-cell receptor, and TGF-β/SMAD signaling in the stages of post-transplantation immunorecognition, immunomodulation, and tissue repair, respectively. Furthermore, it highlights the innovative roles of TLR10 and miR-29a-3p in improving transplantation outcomes. An in-depth understanding of the molecular mechanisms underlying the host immune response after decellularized matrix transplantation provides new directions for the repair of tissue defects.

Objective:
To grasp the research dynamics and development trend of the thermal environment of campus buildings in China, so as to lay the foundation for in depth research and provide a reference basis.
Methods:
Based on 479 documents in CNKI from 2000 to 2020, the documents were visualized and analyzed by keywords, including co occurrence, clustering, outbreak and author cooperation network in CiteSpace.
Results:
In the past 20 years, the research on thermal environment of campus buildings in China had gone through a period of formation development growth, and was at a high growth stage now. The word frequency of "thermal comfort, thermal environment, indoor thermal environment, natural ventilation" was greater than 50, which was a high frequency keyword. The highest outbreak rate of "green campus" was 3.75, and "university library, university building, microclimate and green building" was in the outbreak period. And LIU Jiaping, LIU Zehua, WANG Hongguang and others were highly productive authors and have formed cooperative network groups with their own cores, but the cooperation among the network groups was less to be strengthened.
Conclusion
The research dynamics of the thermal environment of campus buildings is closely related to the policy development in China, and the research on "green campus, campus energy saving optimization, and university buildings" based on human thermal comfort theory is a hot topic of continuous attention.
