Objective:To investigate the mechanism of curcumin affecting HIV-1 infection co-receptor CCR5 by regulating transcription factor FOXP3.Methods:Binding sites of transcription factor FOXP3 on CCR5 promoter were predicted and analyzed by bioinformatics method.AutoDock 4.2 software was used to connect curcumin and FOXP3 flexibly.MTT assay was used to detect cyto-toxcity of curcumin on activity of Jurkat cells.qRT-PCR and Western blot were used to detect expression levels of CCR5 and FOXP3 mRNA and protein in Jurkat cells that were treated with different concentrations of curcumin.pcDNA3.1-FOXP3 expression vector was built and combined with the prediction results of transcription factors.The mutant CCR5 gene fragment was amplified by Overlap PCR,and the mutant CCR5 promoter recombinant vector pFireRluc-Mt-CCR5 was constructed.Binding site between transcription fac-tor FOXP3 and CCR5 promoter was verified by double luciferase reporter gene assay.Results:Results of JASPAR transcription factor prediction showed that there was a binding site between CCR5 promoter and transcription factor FOXP3;molecular docking results showed that curcumin could bind to the active region of FOXP3;MTT results showed that curcumin inhibited the activity of Jurkat cells after 24 hours,and the IC50 was 34.48 μmol/L.qRT-PCR and Western blot showed that expression levels of CCR5 and FOXP3 mRNA and protein were decreased in a dose-dependent manner after different concentrations of curcumin treated Jurkat cells;double luciferase reporter gene confirmed that FOXP3 could bind to CCR5 promoter,and the transcription factor FOXP3 could regulate the activity of CCR5 promoter;results of the recovery experiment of FOXP3 on curcumin showed that when the curcumin concentration was 60 μmol/L,relative value of luciferase activity in HEK293T cells with pcDNA3.1-FOXP3 and pFireRluc-Wt-CCR5 was signifi-cantly higher than that in pFireRluc-Wt-CCR5+curcumin-60 group(P<0.01).Conclusion:FOXP3 can regulate the activity of CCR5 promoter,and the mechanism may be that curcumin affects activity of CCR5 promoter by acting on binding site of FOXP3 and CCR5 promoter.

Objective This study was to develop a"Spleen Deficiency Certificate Scale for County Residents"and test its reliability.It was then developed as an objective tool for Chinese medicine evidence and symptoms for the prevention and control of chronic diseases among county residents.Methods The scale was compiled based on the team's previous foundation.The reliability of the scale was evaluated using internal consistency reliability and split-half reliability,while its validity was evaluated using structural validity,content validity,calibration validity,and discriminant validity.Results The study included 213 adults from Lanxi,of whom 155 were tested for intestinal flora.Seven scale entries were identified:Fatigue,fear of cold,bland mouth,loss of appetite,diarrhea,weak bowel movements,and tooth-marked tongue.In the reliability test,Cronbach's alpha coefficient was 0.828 and McDonald's ω coefficient was 0.825.The"stomach pain"and"bloating"entries did not meet the inclusion requirements and were recommended to be deleted.The Spearman-Brown coefficient was 0.839.The exploratory factor analysis of the two common factors explained 61.6%of the cumulative variance.The calibration validity indicated that the ratio of salivary amylase activity before and after acid stimulation was 0.826±0.253 in the group with spleen deficiency.Significant differences(P<0.05)in the genera Dialister,Shigella,Leuconostoc,Photobacterium,Trabulsiella,and Parvimonas between the spleen deficiency group and the non-spleen deficiency group.Conclusion The Spleen Deficiency Scale for County Residents demonstrates good reliability and validity.

The killing effect of radiation therapy on healthy cells has led to the creation of targeted radionuclide therapy,which effectively reduces the damage to surrounding normal cells.At present,alpha(α)and beta(β)radionuclides are the research hotspots of targeted therapy.Numerous preclinical and clinical studies have shown that radiation therapy not only has local anti-tumor effects,but also exerts systemic anti-tumor effects by triggering the body's immune response.This paper describes in detail the characteristics and clinical applications of commonly used radionuclides,and discusses the mechanism of radiation-triggered body immune response as well as the related research on the combined use of radiation therapy,targeted radionuclide therapy and immunotherapy.

Targeted radiation therapy using radionuclides is a favored approach for treating tumors.This procedure involves the delivery of drugs to the lesion site via carriers or interventional methods,followed by the emission of radiation energy that selectively irradiates the lesion tissue.This approach minimizes damage to normal tissue and achieves the desired therapeutic effect.Factors such as the type of therapeutic radionuclide,radiation energy,physical half-life,method of preparation,and toxicity determine their clinical application.In this paper,the characteristics and clinical application of therapeutic radionuclides were reviewed to providing reference for the clinical application of targeted therapeutic radionuclides.

Radiopharmaceuticals play an important role in the medical field,but they also carry certion risks and potential safety concerns.Medical institutions implement pharmacovigilance to ensure the safety of patients'drug use,including the safety of Radiopharmaceuticals.The operation and management of the pharmacovigilance system in the United States and the European Union are relatively mature.China can learn from their advanced concepts and establish our own radiopharmaciligence system.

Objective It conducted a grounded theory on the factors influencing the sense of job significance of hospital administrators to provide suggestions and references for the promotion of high-quality development of hospital management work.Methods From April to September 2023,it interviewed 23 administrators from various departments across Provinces/Cities,including Zhejiang,Heilongjiang,Guangdong,Shanghai,Henan,Jilin,Sichuan and others,using a theoretical sampling method.Employing Grounded Theory,it encoded over transcriptional information at three levels.Results Three-level coding process yielded 66 free nodes,19 initial concepts,7 main categories,and 3 dimensions,leading to the development of a theoretical model encompassing existence,relatedness,and growth.Conclusion The job meaning for hospital administrators is shaped by existence,relatedness,and growth.It recommend revising performance assessments,fostering an empowering culture,enhancing informal communication,providing professional growth pathways,and offering diverse career development options to deepen administrators'job meaning.
