Objective To investigate the clinical comprehensive value of finerenone in the treatment of diabetic nephropathy(DN),and to provide evidence-based medicine evidence for clinical drug decision.Methods PubMed,Web of Science,Embase,Cochrane Library,WanFang Data,CNKI and health technology assessment(HTA)official website were systematically searched to collect the systematic review/Meta-analysis and pharmacoeconomic evaluation on finerenone in treatment of DN from the inception to November 31,2023.The method of rapid HTA was used to evaluate the effectiveness,safety and economic evaluation.The innovation,suitability and accessibility of finerenone were analyzed by relevant data from drug instructions,professional websites such as the National Medical Products Administration(NMPA)and Center for Drug Evaluation,NMPA.Results In terms of effectiveness,finerenone significantly reduced the risk of the renal composite events and composite cardiovascular outcomes in DN compared with placebo and traditional mineralocorticoid receptor antagonist(MRA).In terms of safety,the incidence of adverse reactions and acute kidney injury of finerenone was similar to that of placebo and traditional MRA,but the incidence of hyperkalemia was higher than that of placebo.In terms of economy,two foreign HTA reports showed that finerenone was more economical than standard treatment.In terms of innovation,finerenone was the world's first approved non-steroidal,selective MRA innovative drug for the treatment of type 2 DN,making its efficacy and adverse reactions more advantageous.In terms of suitability,finerenone should only be taken once a day,which had good suitability in pharmaceutical properties and clinical use.In terms of accessibility,the domestic price of finerenone was lower than the international price,and it was included in the medical insurance,and the market coverage was high,it had a good affordability and availability.Conclusion Finerenone has good effectiveness and safety in the treatment of DN,but attention should be paid to the risk of hyperkalemia,and its economy requires further economic research in China.As the world's first approved non-steroidal,selective MRA innovative drug,finerenone has better innovation,suitability and accessibility.

Background::Although some well-established oncogenes are involved in cancer initiation and progression such as prostate cancer (PCa), the long tail of cancer genes remains to be defined. Goosecoid ( GSC) has been implicated in cancer development. However, the comprehensive biological role of GSC in pan-cancer, specifically in PCa, remains unexplored. The aim of this study was to investigate the role of GSC in PCa development. Methods::We performed a systematic bioinformatics exploration of GSC using datasets from The Cancer Genome Atlas, Genotype-Tissue Expression, Gene Expression Omnibus, German Cancer Research Center, and our in-house cohorts. First, we evaluated the expression of GSC and its association with patient prognosis, and identified GSC-relevant genetic alterations in cancers. Further, we focused on the clinical characterization and prognostic analysis of GSC in PCa. To understand the transcriptional regulation of GSC by E2F transcription factor 1 ( E2F1), we performed chromatin immunoprecipitation quantitative polymerase chain reaction (qPCR). Functional experiments were conducted to validate the effect of GSC on the tumor cellular phenotype and sensitivity to trametinib. Results::GSC expression was elevated in various tumors and significantly correlated with patient prognosis. The alterations of GSC contribute to the progression of various tumors especially in PCa. Patients with PCa and high GSC expression exhibited worse progression-free survival and biochemical recurrence outcomes. Further, GSC upregulation in patients with PCa was mostly accompanied with higher Gleason score, advanced tumor stage, lymph node metastasis, and elevated prostate-specific antigen (PSA) levels. Mechanistically, the transcription factor, E2F1, stimulates GSC by binding to its promoter region. Detailed experiments further demonstrated that GSC acted as an oncogene and influenced the response of PCa cells to trametinib treatment. Conclusions::GSC was highly overexpressed and strongly correlated with patient prognosis in PCa. We found that GSC, regulated by E2F1, acted as an oncogene and impeded the therapeutic efficacy of trametinib in PCa.

Immunotherapy is an important breakthrough in canc-er treatment.Unfortunately,low drug concentration in tumor sites almost ineffectively initiates immune responses and thereby severely limits immune therapy applications in clinics.Nanoma-terials are well-recognized drug delivery system in cancer thera-py.Nanographene oxide(NGO)have shown immense perti-nence for anti-cancer drug delivery owing to their ultra-high sur-face area,chemical stability,good biocompatibility and excel-lent photosensitivity.In addition,functionalized modifications on the surface of NGO increase tumor targeting and minimize cy-totoxicity.This study focuses on reviewing the literature and up-dates on NGO in drug delivery and discussing the possibilities and challenges of NGO in cancer synergetic therapy.

DPP4 is a serine exopeptidase that is immobilized on the cell membrane and plays a crucial regulatory role in various physiological and pathological activities within the human body.In addition to acting as a transcription factor to regulate the tran-scription and expression of downstream target genes,DPP4 also functions as a transcription-independent regulator through pro-tein-protein interactions.In recent studies,DPP4 has been strongly linked to various diseases,and several substances with the potential to target DPP4 have been identified.This paper mainly reviews the multifunctionality of DPP4 in regulating vari-ous aspects of energy metabolism,inflammation,tissue repair and carcinogenesis in the body.It also reviews the screening of in vitro inhibitors of DPP4 and its research progress in regulating chronic liver disease,based on the pathological development process of chronic liver disease.

Aim To investigate the effect of polyphyl-lin Ⅱ(PP Ⅱ)on autophagy of osteosarcoma(OS)cells and its related molecular mechanism.Methods U2OS and HOS cells were cultured in vitro and treated with different concentrations of PP Ⅱ(5,10,15,20 μmol·L-1)for 24 h.The changes of acid vesicles were detected by AO staining,the autophagosomes was ob-served by transmission electron microscopy,the ex-pressions of LC3B-Ⅱ/LC3B-Ⅰ,p62,caspase-3,cleaved caspase-3 were detected by Western blot,the intracellular reactive oxygen species(ROS)was detec-ted by DCFH-DA fluorescence probe,cell viability was detected by CCK-8,cell apoptosis rate was detected by Annexin V-FITC/PⅠ staining.Results PP Ⅱ signifi-cantly increased the number of acidic vesicles(P＜0.05,P＜0.01)and autophagosomes.PP Ⅱ signifi-cantly up-regulated the ratio of LC3B-Ⅱ/LC3B-Ⅰ,and down-regulated the expression level of p62 protein in a concentration-and time-dependent manner(P＜0.05,P＜0.01).PP Ⅱ significantly increased intra-cellular ROS levels(P＜0.01).Autophagy inhibitor 3-MA and CQ could reverse the regulation of cell via-bility,autophagy and apoptosis related proteins by PP Ⅱ in U2OS cells,endoplasmic reticulum stress inhibi-tor 4-PBA could also reverse the regulation of autoph-agy related proteins by PP Ⅱ in U2OS cells.Conclu-sion PP Ⅱ promotes OS cell autophagy by mediating ROS and endoplasmic reticulum stress.
