The recombinant human thyroid-stimulating hormone (rhTSH) can be used for differentiated thyroid cancer (DTC) preparation before ¹³¹I therapy, and follow-up. Since its approval by the American Food and Drug Administration (FDA) in 1998, rhTSH has been clinically used in European countries, the United States, and other countries for nearly 30 years. In April 2024, China’s first independently developed rhTSH agent was approved. Based on clinical experience and evidence from domestic and international studies, an expert consensus on the application of rhTSH has been developed following thorough consultations among experts. The consensus offers evidence-based recommendations to guide the appropriate use of rhTSH in clinical practice.

Hypospadias is a common congenital malformation of the genitourinary system in children. Surgery is the only way to treat hypospadias. The anatomical conditions of the penis directly affect the choice of surgical methods and prognosis. It is urgent to establish an individualized surgical strategy to adapt to different types of hypospadias in order to improve the prognosis of children. Therefore，this paper focuses on the evaluation of hypospadias anatomy，selection of surgical methods and postoperative efficacy，in order to provide reference for the establishment of individualized surgical strategies for hypospadias.

AIM:To investigate the effect of silent information regulator 1(SIRT1)on the degree of aging and apoptosis in a mouse cardiomyocyte aging model through the regulation of Wnt/β-catenin pathway.METHODS:An in vi-tro aging model was established by inducing HL-1 cells with 40 μmol/L D-galactose(D-Gal).The HL-1 cells were trans-fected with a lentivirus overexpressing SIRT1,and the transfection efficiency was verified by Western blot.Western blot was used to detect the protein expression levels of SIRT1,P53,P21,cleaved caspase-3,B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),β-catenin,Wnt3a and c-Myc.Senescence-associated β-galactosidase(SA-β-Gal)staining was used to detect cellular senescence level.MTT colorimetric assay was used to detect the cell viability,and flow cytometry was used to detect the apoptosis.RESULTS:Treatment of HL-1 mouse cardiomyocytes with D-Gal led to in-creases in the expression levels of aging-related proteins P53 and P21,as well as an increase in SIRT1 protein level.Addi-tionally,the SA-β-Gal staining showed a significant increase in the positive area(P＜0.05).The expression levels of apop-tosis-related proteins cleaved caspase-3 and Bax were elevated,while the level of the anti-apoptotic protein Bcl-2 was re-duced(P＜0.05).There was a marked decrease in cell viability(P＜0.05),and flow cytometry analysis demonstrated a significant increase in cell apoptosis rate(P＜0.05),which was positively correlated with the duration of D-Gal treatment.Overexpression of SIRT1 notably reduced both aging and apoptosis levels after 48 h of D-Gal treatment(P＜0.05).After D-Gal treatment,the expression levels of β-catenin,c-Myc and Wnt3a proteins were up-regulated.However,these levels were reduced when SIRT1 was overexpressed.Moreover,the addition of LiCl,a Wnt/β-catenin pathway agonist,resulted in increased expression levels of β-catenin,c-Myc and Wnt3a proteins compared with the group with SIRT1 overexpres-sion and D-Gal treatment(P＜0.05).CONCLUSION:SIRT1 inhibits cardiomyocyte apoptosis and alleviates cardiomyo-cyte aging through the Wnt/β-catenin pathway.

Objective To explore the role of ferroptosis in DIC through bioinformatics analysis of hub genes involved in ferroptosis in doxorubicin-induced cardiomyopathy(DIC),combined with in vitro experimental validation.Methods Divalent iron fluorescence staining confirms the occurrence of ferroptosis in myocardial cells of DIC.The GSE207737 dataset was retrieved from the Gene Expression Comprehensive Database(GEO)and intersected with the FerrDb database to identify ferroptosis-related genes.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses of the intersected genes and intersecting the genes obtained from LASSO regression analysis and SVM-SFR machine learning methods were used to obtain ferroptosis hub genes for DIC.Real-time PCR was used to validate H9C2 cells in the control and DIC model groups,and Western blotting was used to further validate those whose bioinformatics and real-time PCR results that did not match.Results Thirty-eight ferroptosis-related genes in DIC were identified,and GO and KEGG analyses showed that these genes mainly participate in cell metabolism.Five hub genes for ferroptosis in DIC were obtained using machine learning methods:Mpc1,Prdx1,Kdm4a,Alox 12b,and Tfrc.Through in vitro experiments,the mRNA expression levels of Mpc1,Prdx1,and Kdm4a were downregulated in the DIC model group compared to those in the control group(P＜0.001),whereas the mRNA expression level of Alox12b was upregulated(P＜0.001).There were no significant differences in the mRNA or protein expression levels of Tfrc(P＞0.05).Conclusion Mpc1,Prdx1,Kdm4a,and Alox12b are key genes involved in ferroptosis in doxorubicin-induced cardiomyopathy and potential targets for the prevention and treatment of doxorubicin-induced cardiomyopathy in ferroptosis.

Objective To investigate the mechanism of Guizhi Tongluo Tablets(GZTLP)on improving atherosclerosis in APOE knockout mice by regulating neutrophil extracellular trapping nets(NETs).Methods After modeling,24 APOE knockout mice aged 8 weeks were randomly divided into 4 groups:GZTLP high-dose group,low-dose group,model control group and normal control group,with 6 mice in each group.GZTLP was given 1.87 mg·g-1 and 0.47 mg·g-1 intragastric administration in high-dose group and low-dose group,respectively.The normal control group and model control group were given 0.9%sodium chloride solution intragastric administration for 6 weeks,and the lipid plaque deposition in aorta was observed by gross oil red O staining.Lipid deposition in aortic root was observed by oil red O staining.The pathological changes of lipid plaques in aortic root were observed by HE staining.The levels of interleukin-1β(IL-1β)and tumor necrosis factor α(TNF-α)in peripheral blood of mice were detected by enzyme-linked immunosorbent assay(ELISA).The expression of lymphocyte antigen 6G(Ly6G),myeloperoxidase(MPO)and citrulinated histone(Cit-H3)in plaques of the aortic arch and the colocalization of Ly6G,MPO and Cit-H3 were detected by immunofluorescence assay.Results Compared with the normal control group,the aorta of mice in the model control group showed serious lipid plaque deposition,morphological damage,and a large number of inflammatory cells infiltration,the contents of serum inflammatory factors IL-1β and TNF-α were increased,and the protein expressions of Ly6G,Cit-H3 and MPO were significantly increased.Compared with model control group,GZTLP group reduced the amount of lipid plaque deposition in aorta,the arrangement of aortic cells was more regular,the inflammatory cell infiltration was improved,and the contents of serum inflammatory factors IL-1β and TNF-α were significantly decreased(P<0.05).The colocalization and the protein expression of Ly6G,MPO and Cit-H3 were significantly decreased in aortic tissues(P<0.01).Conclusions GZTLP can improve atherosclerosis,and its mechanism may be related to the inhibition of neutrophil extracellular trapping nets.

Objective: To study the serum interleukin-37 (IL-37) level changes in patients with acute coronary syndrome (ACS) and to explore the relationship between IL-37 and coronary atherosclerotic plaque.
Methods: Our research included 3 groups. ACS group, n=60, SAP (stable angina pectoris) group, n=30 and Control group, the subjects with normal coronary artery, n=15. The peripheral serum levels of IL-37 were examined by ELISA and the differences were compared among different groups.
Results: ① The serum levels of IL-37 at admission were as ACS group < SAP group < Control group, P<0.05.②Intervention could transitionally decrease IL-37 level in SAP group. With 4 weeks treatment, IL-37 levels were signiifcantly increased in both ACS group and SAP group than admission time, while they were still lower than Control group, P<0.05.③The serum level of IL-37 at admission was negatively related to IL-18 (r=-0.79, P<0.05), the ratio of IL-18/IL-37 were as ACS group>SAP group>Control group, P<0.05.④In ACS group, IL-37 level was negatively related to GRACE score (r=-0.71, P<0.05), the ratio of IL-18/IL-37 was positively related to GRACE score (r=0.73, P<0.05).⑤The diagnosis of ACS could be basically excluded if the patients with IL-37>77ug/L.
Conclusion: The serum IL-37 might be involved in the inlfammatory process in ACS patients, it could be expected as an index for ACS monitor and evaluation in clinical practice.
