This paper elaborates on the generation and characteristics of plasma, as well as its mechanisms of action on cancer cells when used alone, including the production of reactive oxygen and nitrogen species, and damage to cancer cell membranes, and organelles. It emphasizes the synergistic mechanisms observed when plasma is combined with various anticancer drugs (e.g., chemotherapeutic agents, targeted drugs, and immunotherapies). The analysis focuses on enhancing drug uptake, promoting the activation of drug action targets, and improving the tumor microenvironment. These insights provide a theoretical basis for optimizing plasma-drug combination therapy for cancer.展开更多

文摘Background:The increasing incidence of cancers and infectious diseases worldwide presents a significant public health challenge that requires immediate intervention.Our strategy to tackle this issue involves the development of pharmaceutical formulations that combine phytopolyphenols(P),targeted drugs(T),and metal ions(M),collectively referred to as PTM regimens.The diverse pharmacological properties of PTM regimens are hypothesized to effectively reduce the risk factors associated with both cancers and infectious diseases.Methods:The effects of the pharmaceutical agents on the proliferation of cultured cancer cells and pathogens were assessed after 72 h and 48 h,respectively,using the MTT(3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide)assay and optical density at 600 nm(OD600).The synergistic effects of drug combinations were evaluated by combination index(CI),where CI<1 indicates synergism,CI=1 indicates addition,and CI>1 indicates antagonism.Efficacy index(EI)was also calculated.Assays of efflux pump ATPase activities were conducted using a colorimetric method.Results:This study evaluated the anticancer and antibacterial efficacy of PTM regimens that included phytopolyphenols(specifically curcumin(C)and green tea polyphenols(G)),repurposed drugs(memantine(Mem),thioridazine(TRZ),cisplatin(Cis),and 5-fluorouracil(5FU)),and ZnSO_(4)(Zn)across three cultured cancer cell lines and four cultured pathogens.The most effective regimens,GC·Mem·Zn and GC·TRZ·Zn,significantly enhanced the anticancer efficacy(EI)of cisplatin across the three cancer lines(OECM-1,A549 and DLD-1)by 7,11 and 21;7,9,and 17 fold,respectively,while the enhancements for 5-fluorouracil were 5,6 and 12;5,5 and 9 fold,respectively.Furthermore,these PTM regimens demonstrated substantial synergistic inhibition of Na^(+)-K^(+)-Mg^(2+)-ATPase and Mg^(2+)-ATPase in the cultured cancer cells,as well as a reduction in biofilm formation by the four cultured pathogens,suggesting their potential to address the challenges of multidrug resistance in cancers and infectious diseases.Conclusion:Given that all drugs incorporated in the PTM regimens have been clinically validated for safety and efficacy,particularly regarding their synergistic selective anticancer efficacy,inhibition of efflux pump ATPase,and antibiofilm formation of pathogens,these regimens may offer a promising therapeutic strategy to alleviate the severe side effects and drug resistance typically associated with chemotherapeutic agents.Further preclinical and clinical investigations are warranted.

文摘Background Hypertension is associated with an increased risk of calcific aortic valve stenosis(CAVS).However,the directionality of causation between blood pressure traits and aortic stenosis is unclear,as is the benefit of antihypertensive drugs for CAVS.Methods Using genome-wide association studies(GWAS)summary statistics,we performed bidirectional two-sample univariable mendelian randomization(UVMR)to assess the causal associations of systolic blood pressure(SBP),diastolic blood pressure(DBP),and pulse pressure(PP)with CAVS.Multivariable mendelian randomization(MVMR)was conducted to evaluate the direct effect of hypertension on CAVS,adjusting for confounders.Drug target mendelian randomization(MR)and summary-level MR(SMR)were used to estimate the effects of 12 classes of antihypertensive drugs and their target genes on CAVS risk.Inverse variance weighting was the primary MR method,with sensitivity analyses to validate results.Results UVMR showed SBP,DBP,and PP have causal effects on CAVS,with no significant reverse causality.MVMR confirmed the causality between hypertension and CAVS after adjusting for confounders.Drug-target MR analyses indicated that calcium channel blockers(CCBs),loop diuretics,and thiazide diuretics via SBP lowering exerted protective effects on CAVS risk.SMR analysis showed that the CCBs target gene CACNA2D2 and ARBs target gene AGTR1 were positively associated with CAVS risk,while diuretics target genes SLC12A5 and SLC12A1 were negatively associated with aortic stenosis risk.Conclusions Hypertension has a causal relationship with CAVS.Managing SBP in hypertensive patients with CCBs may prevent CAVS.ARBs might exert protective effects on CAVS independent of blood pressure reduction.The relationship between diuretics and CAVS is complex,with opposite effects through different mechanisms.
