The One Health concept aims to achieve the joint health security of humans, animals and environments through cross-disciplinary, cross-sector and cross-field collaborations. This review summarizes the development of One Health and the successful practices in the prevention and control of echinococcosis, rabies, COVID-19 and schistosomiasis, as well as explores the challenges faced in applying this concept to the prevention and control of zoonoses, so as to provide insights into formulation of the integrated zoonoses control strategy and implementation of zoonoses control interventions at the human-animal-environment interface.

Objective: To explore the potential application of PAK4-PROTAC targeted degradation drug (PpD) in renal cancer immunotherapy. Methods: TIMER 2.0 and TISIDB databases were used to analyze the relationship among PAK4 expression, tumor purity and abundance of immune cell infiltration in renal tumor microenvironment (TEM).Renal cancer cell lines OS-RC-2, 786-O and ACHN were treated with 0, 125 and 250 nmol/L PpD, and the effects of Jurkat cell co-culture on the results were investigated.The cell apoptosis was detected with flow cytometry, and the expression of programmed cell death 1 ligand 1 (PD-L1) in renal cancer cells was detected with immunoblotting. Results: The high expression of PAK4 was positively related to immune purity, and inhibited the abundance of immune killer cells in TEM, such as CD8 T cells, CD4 T cells, natural killer cells and dendritic cells.With 250 nmol/L PpD treatment, there were 21.02% apoptotic cells in OS-RC-2, 29.67% apoptotic cells in 786-O, and 15.39% apoptotic cells in ACHN, respectively.However, with the same concentration of 250 nmol/L PpD treatment, cell apoptotic rate was sharply increased to 70.13% in OS-RC-2/Jurkat, 70.68% in 780-O/Jurkat, and 60.27% in ACHN/Jurkat co-culture models, respectively. Conclusion: PpD can promote apoptosis of renal cancer cells by reducing the expression of PAK4 protein, and enhance the killing effects of immune cells on tumor cells.

Along with enriching the graduate course system， the study explores innovative approaches and methods for graduate education and teaching in PTCM， and reflects on the challenges in course system construction and teaching， serving as a reference for improving the quality of graduate training， promoting the development of the PTCM discipline， and advancing teaching reform practices.

Objective To analyze the incidence of prehypertension (PHTN) and hypertension of male workers in a coal mine and investigate the influencing factors. Methods A total of 10 155 male workers in a coal mine in Shanxi Province were selected as the study subjects using the judgment sampling method. Occupational medical examination was carried out to examine the prevalence of abnormal blood pressure (including PHTN and hypertension) and its influencing factors. Results The prevalence of abnormal blood pressure was 69.9%, with a PHTN prevalence of 44.2% and a hypertension prevalence of 25.7%. The results of multinomial logistic regression analysis showed that the risk of PHTN and hypertension increased with age, drinking frequency and body mass index (all P<0.05). Workers with a pulse rate≥100 times/min had a higher risk of PHTN and hypertension than those with a pulse rate of 60-100 times/min (all P<0.05). The risk of PHTN and hypertension in workers exposed to noise, silica dust or other dust was higher than those without such occupational hazard exposure (all P<0.05). The risk of hypertension in workers with abnormal blood glucose was higher than that in workers with normal blood glucose (P<0.05). Exposure to organic solvents was associated with a higher risk of hypertension (P<0.05). Conclusion The prevalence of PHTN and hypertension among male coal miners in this mine is relatively high. The individual factors such as age, alcohol consumption, pulse rate, and body mass index, along with occupational exposure factors such as noise, silica dust, and other dusts, are influencing factors for PHTN and hypertension.

Objective To investigate the mechanism of metformin for regulating tumor-stromal cell cross-talk in breast cancer.Methods Tumor associated fibroblasts(CAFs)co-cultured with breast cancer cells were treated with metformin,and the changes in expressions of hypoxia-inducible factor-1α(HIF-1α),p-AMPK,stroma-derived factor-1(SDF-1)and interleukin-8(IL-8)in the CAFs were detected using ELISA,RT-qPCR or Western blotting;Transwell assay was used to evaluate the invasiveness of the tumor cells and its changes following treatment with exogenous SDF-1,IL-8 and TGF-β1.The effects of HIF-1α shRNA or overexpression plasmid,AMPK shRNA,and treatment with OG(a proline hydroxylase inhibitor)or 2-OXO(a proline hydroxylase activator)were examined on p-AMPK,HIF-1α,SDF-1 and IL-8 expressions and invasiveness of the CAFs.Results Metformin treatment significantly increased the expression levels of p-AMPK,SDF-1 and IL-8(P<0.05)and decreased HIF-1α expression(P<0.05)without affecting AMPK expression level(P>0.05)in the CAFs.The invasion ability of metformin-treated breast cancer cells was significantly decreased(P<0.05).Exogenous SDF-1 and IL-8,HIF-1α overexpression,and OG-induced upregulation of HIF-1α all significantly attenuated the inhibitory effects of metformin on breast cancer cell invasion(P<0.05)and HIF-1α,SDF-1 and IL-8 expressions in CAFs(P<0.05).Transfection with HIF-1α shRNA or treatment with 2-OXO significantly decreased the invasiveness of breast cancer cells(P<0.05).P-AMPK knockdown significantly suppressed the inhibitory effect of metformin on HIF-1α expression in CAFs and on invasion of breast cancer cells(P<0.05).Treatment with TGF-β1 partially decreased the inhibitory effect of metformin on HIF-1α expression in CAFs and invasiveness of the breast cancer cells(P<0.05).Conclusion Metformin suppresses HIF-1α expression in CAFs to block tumor-stromal cross talk in breast cancer.
