The time-dependent accretion of cellular lesions is generally a universal trigger of aging, while mitochondrial dysfunction is a sign of aging. Dysfunctional mitochondria are identified and removed by mitophagy, a selective form of macroautophagy. Increased mitochondrial damage resulting from reduced biogenesis and clearance may promote the aging process. The primary purpose of this paper is to illustrate in detail the effects of mitophagy on aging and emphasize the associations between mitophagy and other signs of aging, including dietary restriction, telomere shortening, epigenetic alterations, and protein imbalance.The evidence regarding the effects of these elements on aging is still limited. And although the understanding of relationship between mitophagy and aging has been long-awaited, to analyze details of such a relationship remains the main challenge in aging studies.展开更多

Pancreatic pa...Solid pseudopapillary tumor of the pancreas(SPTP), also known as solid and papillary epithelial neoplasm of the pancreas, is a rare pancreatic exocrine tumor that is difficult to diagnose before surgery. Pancreatic panniculitis is a rare type that occurs in less than 3% of all patients with pancreatic diseases. We here report a 19-year-old woman who presented with persistent left upper quadrant pain without obvious cause for 1 d. The patient also developed subcutaneous nodules involving lower abdomen bilaterally and lower limbs, and subcutaneous nodules were pathologically diagnosed as pancreatic panniculitis. Plain abdominal computed tomography revealed a soft-tissue mass in the body and tail of the pancreas, which was closely associated with the gastric wall. Contrast-enhanced ultrasound showed inhomogeneous echogenicity in the anterior pancreatic body, which had blurred parenchymal demarcation of the body and tail of the pancreas. Contrast-enhanced abdominal computed tomography revealed a mixed density mass with solid and cystic components in the body and tail of the pancreas, and the solid component was markedly enhanced. The lesion was pathologically diagnosed as SPTP after laparoscopic resection.

文摘BACKGROUND Helicobacter pylori(H.pylori)infection can cause extensive apoptosis of gastric epithelial cells,serving as a critical catalyst in the progression from chronic gastritis,gastrointestinal metaplasia,and atypical gastric hyperplasia to gastric carcinoma.Prompt eradication of H.pylori is paramount for ameliorating the pathophysiological conditions associated with chronic inflammation of the gastric mucosa and the primary prevention of gastric cancer.Acacetin,which has multifaceted pharmacological activities such as anti-cancer,anti-inflammatory,and antioxidative properties,has been extensively investigated across various domains.Nevertheless,the impact and underlying mechanisms of action of acacetin on H.pylori-infected gastric mucosal epithelial cells remain unclear.AIM To explore the defensive effects of acacetin on apoptosis in H.pylori-infected GES-1 cells and to investigate the underlying mechanisms.METHODS GES-1 cells were treated with H.pylori and acacetin in vitro.Cell viability was assessed using the CCK-8 assay,cell mortality rate via lactate dehydrogenase assay,alterations in cell migration and healing capacities through the wound healing assay,rates of apoptosis via flow cytometry and TUNEL staining,and expression levels of apoptosis-associated proteins through western blot analysis.RESULTS H.pylori infection led to decreased GES-1 cell viability,increased cell mortality,suppressed cell migration,increased rate of apoptosis,increased expressions of Bax and cle-caspase3,and decreased Bcl-2 expression.Conversely,acacetin treatment enhanced cell viability,mitigated apoptosis induced by H.pylori infection,and modulated the expression of apoptosis-regulatory proteins by upregulating Bcl-2 and downregulating Bax and cleaved caspase-3.CONCLUSION Acacetin significantly improved GES-1 cell viability and inhibited apoptosis in H.pylori-infected GES-1 cells,thereby exerting a protective effect on gastric mucosal epithelial cells.

文摘In the inflammatory microenvironment,there are numerous exosomes secreted by immune cells(Macrophages,neutrophils,dendritic cells),mesenchymal stem cells(MSCs)and platelets as intercellular communicators,which participate in the regulation of inflammation by modulating gene expression and releasing anti-inflammatory factors.Due to their good biocompatibility,accurate targeting,low toxicity and immunogenicity,these exosomes are able to selectively deliver therapeutic drugs to the site of inflammation through interactions between their surface-antibody or modified ligand with cell surface receptors.Therefore,the role of exosome-based biomimetic delivery strategies in inflammatory diseases has attracted increasing attention.Here we review current knowledge and techniques for exosome identification,isolation,modification and drug loading.More importantly,we highlight progress in using exosomes to treat chronic inflammatory diseases such as rheumatoid arthritis(RA),osteoarthritis(OA),atherosclerosis(AS),and inflammatory bowel disease(IBD).Finally,we also discuss their potential and challenges as anti-inflammatory drug carriers.

文摘Hepatocellular carcinoma(HCC)is a common malignancy that is driven by multiple genes and pathways.The aim of this study was to investigate the role and specific mechanism of the actin-interacting protein zyxin(ZYX)in HCC.We found that the expression of ZYX was significantly higher in HCC tissues compared to that in normal liver tissues.In addition,overexpression of ZYX in hepatoma cell lines(PLC/PRF/5,HCCLM3)enhanced their proliferation,migration and invasion,whereas ZYX knockdown had the opposite effects(SK HEP-1,Huh-7).Furthermore,the change in the expression levels of ZYX also altered that of proteins related to cell cycle,migration and invasion.Similar results were obtained with xenograft models.The AKT/mTOR signaling pathway is one of the key mediators of cancer development.While ZYX overexpression upregulated the levels of phosphorylated AKT/mTOR proteins,its knockdown had the opposite effect.In addition,the AKT inhibitor MK2206 neutralized the pro-oncogenic effects of ZYX on the HCC cells,whereas the AKT activator SC79 restored the proliferation,migration and invasion of HCC cells with ZYX knockdown.Taken together,ZYX promotes the malignant progression of HCC by activating AKT/mTOR signaling pathway,and is a potential therapeutic target in HCC.

文摘Aging, subjected to scientific scrutiny, is extensively defined as a time-dependent decline in functions that involves the majority of organisms. The time-dependent accretion of cellular lesions is generally a universal trigger of aging, while mitochondrial dysfunction is a sign of aging. Dysfunctional mitochondria are identified and removed by mitophagy, a selective form of macroautophagy. Increased mitochondrial damage resulting from reduced biogenesis and clearance may promote the aging process. The primary purpose of this paper is to illustrate in detail the effects of mitophagy on aging and emphasize the associations between mitophagy and other signs of aging, including dietary restriction, telomere shortening, epigenetic alterations, and protein imbalance.The evidence regarding the effects of these elements on aging is still limited. And although the understanding of relationship between mitophagy and aging has been long-awaited, to analyze details of such a relationship remains the main challenge in aging studies.

文摘Amyloid-beta-induced neuronal cell death contributes to cognitive decline in Alzheimer’s disease.Citri Reticulatae Semen has diverse beneficial effects on neurodegenerative diseases,including Parkinson’s and Huntington’s diseases,however,the effect of Citri Reticulatae Semen on Alzheimer’s disease remains unelucidated.In the current study,the anti-apoptotic and autophagic roles of Citri Reticulatae Semen extract on amyloid-beta-induced apoptosis in PC12 cells were first investigated.Citri Reticulatae Semen extract protected PC12 cells from amyloid-beta-induced apoptosis by attenuating the Bax/Bcl-2 ratio via activation of autophagy.In addition,Citri Reticulatae Semen extract was confirmed to bind amyloid-beta as revealed by biolayer interferometry in vitro,and suppress amyloid-beta-induced pathology such as paralysis,in a transgenic Caenorhabditis elegans in vivo model.Moreover,genetically defective Caenorhabditis elegans further confirmed that the neuroprotective effect of Citri Reticulatae Semen extract was autophagy-dependent.Most importantly,Citri Reticulatae Semen extract was confirmed to improve cognitive impairment,neuronal injury and amyloid-beta burden in 3×Tg Alzheimer’s disease mice.As revealed by both in vitro and in vivo models,these results suggest that Citri Reticulatae Semen extract is a potential natural therapeutic agent for Alzheimer’s disease via its neuroprotective autophagic effects.

文摘Iron is one of the necessary metal elements in the human body.There are numerous factors that control the balance of iron metabolism,and its storage and transportation mechanisms are intricate.As one of the most energyintensive tissues in the body,the retina is susceptible to iron imbalance.The occurrence of iron overload in the retina leads to the generation of a significant quantity of reactive oxygen species.This will aggravate local oxidative stress and inflammatory reactions and even lead to ferroptosis,eventually resulting in retinal dysfunction.The blood-retinaretinal barrier is eventually harmed by oxidative stress and elevated inflammation,which are characteristics of retinal vascular disorders.The pathophysiology of retinal vascular disorders may be significantly influenced by iron.Recently,iron-chelating agents have been found to have antioxidative and anti-inflammatory actions in addition to iron chelating.Therefore,iron neutralization is considered to be a new and potentially useful therapeutic strategy.This article reviews the iron overload in retinal vascular diseases and discusses the therapeutic potential of iron-chelating agents.
文摘Introduction About 72%of human genome is transcribed to non-coding RNAs,which have captivated researchers a lot for shedding light on their pivotal roles in regulating the initiation and progression of various diseases,including cancers[1].Among these,long non-coding RNAs(lncRNAs)have emerged as key players in the complex landscape of gene regulation.LncRNAs perform a variety of roles,including scaffolding to encourage the interaction of related proteins,decoys to thwart transcriptional factors from the target gene’s promoter,sponges of linked miRNA to prevent target gene destruction,and guide molecules to recruit components for chromatin remodeling[1].Many cancers are closely related to age[2-5]and such patients are expected be increased gradually as almost 20%of the world’s population will be 65 or older by 2030[6]and those over the age of 65 have an 11-fold higher incidence of cancer than people under that age[7].As one of the typical hallmarks of aging[8],cellular senescence is Cellular senescence is induced by stressful insults and certain physiological processes and is characterized by a prolonged and essentially irreversible cell-cycle arrest with secretory features,macromolecular damage,and altered metabolism[9].Here,we aim to provide insights of the intersection between lncRNAs,cellular senescence,and urinary tumors,unraveling the potential implications and therapeutic avenues within this multifaceted network.

文摘BACKGROUND Circulating tumor cell(CTC)count and neutrophil-to-lymphocyte ratio(NLR)are both closely associated with the prognosis of hepatocellular carcinoma(HCC).AIM To investigate the prognostic value of combining these two indicators in HCC.METHODS Clinical data were collected from patients with advanced HCC who received im-mune therapy combined with targeted therapy at the Department of Oncology,the Affiliated Hospital of Southwest Medical University,Sichuan,China,from 2021 to 2023.The optimal cutoff values for CTC programmed death-ligand 1(PD-L1)(+)>1 or CTC PD-L1(+)≤1 and NLR>3.89 or NLR≤3.89 were evaluated using X-Tile software.Patients were categorized into three groups based on CTC PD-L1(+)counts and NLR:CTC-NLR(0),CTC-NLR(1),and CTC-NLR(2).The relationship between CTC-NLR and clinical variables as well as survival rates was assessed.RESULTS Patients with high CTC PD-L1(+)expression or NLR at baseline had shorter median progression-free survival(m-PFS)and median overall survival(mOS)than those with low levels of CTC PD-L1(+)or NLR(P<0.001).Mean-while,patients in the CTC-NLR(2)group showed a significant decrease in mPFS and mOS.Cox regression analysis revealed that alpha-fetoprotein(AFP),CTC PD-L1(+),and CTC-NLR were independent predictors of OS.The time-dependent receiver operating characteristic curve showed that the area under the curve of CTC-NLR at 12 months(0.821)and 18 months(0.821)was superior to that of AFP and CTC PD-L1(+).CONCLUSION HCC patients with high CTC PD-L1(+)or NLR expression tend to exhibit poor prognosis,and a high baseline CTC-NLR score may indicate low survival.CTC-NLR may serve as an effective prognostic indicator for patients with advanced HCC receiving immunotherapy combined with targeted therapy.

文摘BACKGROUND The quality of a radiotherapy plan often depends on the knowledge and expertise of the plan designers.AIM To predict the uninvolved liver dose in stereotactic body radiotherapy(SBRT)for liver cancer using a neural network-based method.METHODS A total of 114 SBRT plans for liver cancer were used to test the neural network method.Sub-organs of the uninvolved liver were automatically generated.Correlations between the volume of each sub-organ,uninvolved liver dose,and neural network prediction model were established using MATLAB.Of the cases,70%were selected as the training set,15%as the validation set,and 15%as the test set.The regression R-value and mean square error(MSE)were used to evaluate the model.RESULTS The volume of the uninvolved liver was related to the volume of the corresponding sub-organs.For all sets of Rvalues of the prediction model,except for D_(n0)which was 0.7513,all R-values of D_(n10)-D_(n100)and D_(nmean)were>0.8.The MSE of the prediction model was also low.CONCLUSION We developed a neural network-based method to predict the uninvolved liver dose in SBRT for liver cancer.It is simple and easy to use and warrants further promotion and application.
文摘BACKGROUND As a less invasive technique,peroral endoscopic myotomy(POEM)has recently been widely accepted for treating achalasia with an excellent safety profile,durability,and efficacy in adults.In pediatric and geriatric patients,the treatment is more difficult.AIM To discuss the clinical outcomes of POEM in pediatric and geriatric patients with achalasia.METHODS We conducted a comprehensive search of PubMed,Embase and Cochrane Library databases from inception to July 2024.The primary outcomes were technical and clinical success.Secondary outcomes of interest included adverse events and gastroesophageal reflux disease(GERD).The pooled event rates were calculated by comprehensive meta-analysis software.RESULTS A total of 32 studies with 547 pediatric patients and 810 geriatric patients were included in this study.The pooled event rates of technical success,clinical success,GERD and adverse events of POEM for treating achalasia in pediatric patients were 97.1%[95%confidence interval(CI):95.0%-98.3%;I^(2)=0%;P<0.000],93.2%(95%CI:90.5%-95.2%;I^(2)=0%;P<0.000),22.3%(95%CI:18.4%-26.7%;I^(2)=43.874%;P<0.000)and 20.4%(95%CI:16.6%-24.8%;I^(2)=67.217%;P<0.000),respectively.Furthermore,in geriatric patients,the pooled event rates were 97.7%(95%CI:95.8%-98.7%;I^(2)=15.200%;P<0.000),93.2%(95%CI:90.3%-95.2%;I^(2)=0%;P<0.000),23.9%(95%CI:19.4%-29.1%;I^(2)=75.697%;P<0.000)and 10.8%(95%CI:8.3%-14.0%;I^(2)=62.938%;P<0.000],respectively.CONCLUSION Our findings demonstrated that POEM was an effective and safe technique for pediatric and geriatric patients with achalasia.
文摘Solid pseudopapillary tumor of the pancreas(SPTP), also known as solid and papillary epithelial neoplasm of the pancreas, is a rare pancreatic exocrine tumor that is difficult to diagnose before surgery. Pancreatic panniculitis is a rare type that occurs in less than 3% of all patients with pancreatic diseases. We here report a 19-year-old woman who presented with persistent left upper quadrant pain without obvious cause for 1 d. The patient also developed subcutaneous nodules involving lower abdomen bilaterally and lower limbs, and subcutaneous nodules were pathologically diagnosed as pancreatic panniculitis. Plain abdominal computed tomography revealed a soft-tissue mass in the body and tail of the pancreas, which was closely associated with the gastric wall. Contrast-enhanced ultrasound showed inhomogeneous echogenicity in the anterior pancreatic body, which had blurred parenchymal demarcation of the body and tail of the pancreas. Contrast-enhanced abdominal computed tomography revealed a mixed density mass with solid and cystic components in the body and tail of the pancreas, and the solid component was markedly enhanced. The lesion was pathologically diagnosed as SPTP after laparoscopic resection. Clinicians should be aware of the clinical manifestation, diagnosis, and treatment of pancreatic panniculitis and SPTP.
