文摘Atractylodes macrocephala Koidz.(A.macrocephala)is a medicinal and edible plant species belonging to the Compositae family.Its rhizome serves both therapeutic and nutritional purposes in China.This investigation led to the isolation of thirteen novel rearranged 9(8→7)-abeo-eudesmane-type sesquiterpenoid dimers(SDs),atramacronins A-M(1-13),three eudesmane-type SDs,atramacronins N-P(14-16),and two previously identified meroterpenoids,atrachinenin G(17)and atrachineninΙ(18),from Atractylodes macrocephala.Structure elucidation was accomplished through comprehensive spectroscopic analysis and single-crystal X-ray diffraction.Compounds 1,4-7,9,and 10 exhibited notable cytotoxicity against Hep3B,HepG2,and Huh7 cell lines,with half maximal inhibitory concentration(IC_(50))values ranging from 3.71 to 13.99μmol·L^(-1).
文摘This commentary critically appraises the study by Li et al which pioneered the exploration of the triglyceride-glucose(TyG)index as a prognostic marker in hepatitis B virus-related advanced hepatocellular carcinoma patients undergoing combined camrelizumab and lenvatinib therapy.While we acknowledge the study’s clinical relevance in proposing an easily accessible metabolic biomarker,we delve into the mechanistic plausibility linking insulin resistance to immunotherapy response and angiogenic inhibition.We further critically examine the methodological limitations,including the retrospective design,the populationspecific TyG cut-off value,and unaddressed metabolic confounders.We highlight the imperative for future research to validate its utility across diverse etiologies and treatment settings,and to unravel the underlying immunometabolic pathways.
文摘BACKGROUND Sorafenib has been the conventional treatment for advanced hepatocellular carcinoma(HCC)since 2008.While radiological complete responses are extremely rare,improved supportive care and multidisciplinary approaches in clinical practice may explain the recent increase in case reports and retrospective series documenting such responses.CASE SUMMARY This case series describes 3 patients with advanced HCC who achieved durable complete responses using first-line sorafenib therapy,even in the presence of portal vein thrombosis or extrahepatic spread,and highlights the potential for sustained remission in selected patients.Dermatologic toxicity and non-viral etiology may correlate with favorable outcomes;however,reliable predictive biomarkers for sorafenib response are lacking.CONCLUSION Future research into the etiology and molecular differences in HCC is necessary to develop more personalized therapy options.
文摘BACKGROUND The treatment technology of liver cancer is progressing.In addition to traditional surgical resection,combined therapies of immunotherapy based on immune checkpoint inhibitors,chemotherapy,and transcatheter arterial chemoembolization for hepatocellular carcinoma are more and more widely used.Accurate preoperative diagnosis of liver cancer will provide important information for comprehensive treatment and prognosis evaluation of liver cancer.Sonazoidcontrast-enhanced ultrasound is not only helpful for the qualitative diagnosis of liver lesions,but also has great potential in the diagnosis of histological differentiation of liver cancer.AIM To assess the differentiation of hepatocellular carcinoma(HCC)by utilizing the parameters and imaging features of Sonazoid-contrast-enhanced ultrasound(CEUS).METHODS A retrospective analysis was conducted on the CEUS data of 239 lesions through case-control study.These patients received Sonazoid-CEUS within one week before surgery and were confirmed as HCC by postoperative pathology.Within the cases,patients were further categorized into well-differentiated and poorlydifferentiated group.Time-intensity curves of the region of interest in both arterial and Kupffer phases were generated,allowing for the acquisition of quantitative parameters to assess the diagnostic efficacy in distinguishing lesions between these two groups and determining an appropriate cut-off value.RESULTS Univariate analysis showed that the absolute value of enhancement intensity(EIAV),intensity ratio(IR)and intensity difference(ID)in Kupffer phase were statistically different between the groups with different degree(P=0.015,P=0.000,P=0.000).The sensitivity and specificity were 40.2%,82.4%,80.4% and 78.1%,86.9% and 74.5%,respectively,for differentiating HCC lesions with EIAV≥56.384 dB,IR≥1.215 and ID≥9.184 dB.The area under the receiver operating characteristic curve were 0.590,0.877,0.815.There was no significant difference in the parameters of arterial phase,including peak time,initial growth time,rise time and the absolute value of peak intensity of lesions between the two groups(P>0.05).Multivariate analysis showed that the level of alphafetoprotein(AFP)and IR were risk factors for poor differentiation(P=0.001).CONCLUSION Among the parameters of Sonazoid-CEUS,IR in Kupffer phase exhibits superior diagnostic efficacy with high sensitivity and specificity in the diagnose of pathological differentiation of HCC.Combined with preoperative AFP level,a more accurate diagnosis will be obtained.Compared with portal vein phase,Kupffer phase showed the ability to identify HCC lesions more sensitive.These findings hold significant guiding implications and reference value for clinical practice.

文摘Prostatic carcinoma(PCa)has become one of the most common cancers among men worldwide,with both incidence and mortality rates steadily rising.Although current treatments are effective in the early stages of PCa,many cases eventually progress to castration-resistant prostate cancer(CRPC),and led to treatment failure.To develop new therapeutic strategies to ameliorate the survival of PCa patients then has pressed the need on medicinal researchers.Of traditional Chinese medicinal herbs,Angelica gigas Naka(AGN),and its major pyranocoumarins were broadly reported on the effect of anti-PCa.However,existing reviews mainly focus on decursin(D),decursinol angelate(DA),and decursinol(DOH),without fully exploring other coumarins in AGN.Moreover,most reviews discuss general anticancer effects,with limited emphasis on PCa specifically.This review made a comprehensive summary of the coumarin components of AGN,and depicted the anti-PCa effects and mechanisms,giving a solid research support for drug discovery and development.This review also featured pharmacokinetic advantages and therapeutic potential of DOH,in order to suggest possibilities to overcome the in vivo transformation limitations of D and DA,and shed light on CRPC treatment.We also recommend future studies focus on more in vivo evidence,safety and toxicity evaluation,and clinical validation in humans.

文摘BACKGROUND Rhabdomyosarcoma(RMS)is a type of malignant tumor originating from rhabdomyocytes or mesenchymal cells differentiating into rhabdomyocytes.Hepatic pleomorphic RMS is a rare malignant liver tumor.Hepatic sarcomatoid carcinoma is also a rare epithelial malignant tumor originating from the liver;it is characterized by the coexistence of both carcinomatous and sarcomatoid spindle cell components.CASE SUMMARY This paper reports a special case of an elderly woman whose initial liver puncture biopsy showed pleomorphic RMS.After chemotherapy with the vincristine+doxorubicin+cyclophosphamide regimen,the alpha-fetoprotein level increased significantly.Therefore,a second liver puncture was performed,the pathological result of which was hepatic sarcomatoid carcinoma.Next-generation sequencing revealed MET gene amplification with an average copy number of 9 in the tumor tissue;however,both fluorescence in situ hybridization and immunohistochemical tests were negative for MET amplification.The treatment regimen was adjusted to chemotherapy combined with immunotherapy;however,the disease progressed rapidly,and the overall survival was only 6 months.CONCLUSION By sharing the diagnosis and treatment process of this patient and reviewing the relevant literature,we aim to help clinicians enhance their understanding of two rare diseases,namely pleomorphic RMS and sarcomatoid carcinoma of the liver.

文摘Objective:Hepatocellular carcinoma(HCC)ranks among themost prevalentmalignant tumors globally.Metabolically associated fatty liver disease is a significant risk factor for HCC.Adiponectin,a key regulatory protein in glucolipid metabolism,presents potential as an anti-tumor target in HCC cells.The study focused on evaluating the anti-HCC properties of AdipoRon,an agonist of the adiponectin receptor.Method:Cell viability and proliferation were assessed using the cell counting kit-8 and colony formation assays,respectively.AdipoRon’s effect on HCC cell damage was evaluated via flow cytometry,apoptosis,and(lactate dehydrogenase)LDH assays.Mitochondrial function was evaluated by measuring mitochondrial membrane potential(MMP),ATP levels,and Complex I activity.Additionally,mitochondrial reactive oxygen species(ROS)and calcium(Ca^(2+))levelswere analyzed usingMitoSOXRed and Rhod-2 AM probes,respectively.Results:Our findings indicated that AdipoRon suppressed the proliferation of HCC cells and triggered apoptosis,with both effects being dose-dependent.Furthermore,AdipoRon caused a decrease in mitochondrial membrane potential,ATP levels,and Complex I activity,alongside the generation of mitochondrial ROS.Notably,AdipoRon disrupted intracellular Ca^(2+)homeostasis by causing mitochondrial Ca^(2+)overload due to release fromthe endoplasmic reticulum(ER).Additionally,AdipoRon promoted Ca^(2+)release from the ER by activating the PLC-IP3-IP3R pathway.The resulting mitochondrial Ca^(2+)overload enhances the anti-HCC effect when combined with chemotherapeutic drugs.Conclusions:Therefore,our study demonstrates thatAdipoRon promotesmitochondrial Ca^(2+)overload and apoptosis in HCC cells by activating the PLC-IP3-IP3R signaling pathway.AdipoRon has the potential to become an effective anti-HCC drug.
文摘BACKGROUND Approximately 30%of patients with head and neck cancer experience adverse effects caused by anxiety and depression.Considering the high prevalence,implementing customized interventions to ease adverse emotional states is imperative.AIM To evaluate the efficacy of cognitive behavioral therapy(CBT)-based psychological interventions in improving the psychological well-being and quality of life(QoL)of patients with laryngeal carcinoma.METHODS This study enrolled 120 patients admitted from February 2022 to February 2024.The control group,comprising 50 participants,received standard supportive psychological care,while the research group,consisting 70 participants,underwent CBT-based interventions.Several clinical outcomes were systematically assessed that included postoperative recovery metrics(duration of tracheostomy and nasogastric tube dependence and length of hospitalization),psychological status(Self-Rating Anxiety Scale and Self-Rating Depression Scale),nutritional markers(serum albumin and hemoglobin levels),sleep quality(Self-Rating Scale of Sleep and Athens Insomnia Scale),and QoL(Functional Assessment of Cancer Therapy-Head and Neck).RESULTS The results demonstrated that the research group experienced superior outcomes,with significantly reduced durations of tracheostomy and nasogastric tube dependence,as well as shorter hospital stays,compared with the control group.Additionally,the research group exhibited markedly lower post-intervention Self-Rating Anxiety Scale,Self-Rating Depression Scale,Self-Rating Scale of Sleep,and Athens Insomnia Scale scores,along with minimal but higher change in serum albumin and hemoglobin levels compared with the control group.All five domains of Functional Assessment of Cancer Therapy-Head and Neck showed notable improvements in the research group,exceeding those observed in the control group.CONCLUSION CBT-based psychological support positively affects the mental well-being and QoL of patients with laryngeal carcinoma,highlighting its potential for broader clinical application.

文摘Background:The regulatory mechanisms governing vasculogenic mimicry(VM)in oral squamous cell carcinoma(OSCC)remain largely undefined.This study aimed to identify critical factors and elucidate the epigenetic mechanisms underlying VM in OSCC.Methods:Bioinformatics analysis was performed utilizing single-cell RNA-seq,bulk RNA-seq,and histone H3 lysine 27 acetylation(H3K27ac)Chromatin Immunoprecipitation(ChIP)-seq data obtained from The Cancer Genome Atlas(TCGA)and Gene Expression Omnibus(GEO)databases.ChIP-qPCR was used to validate the binding of ETS transcription factor ELK4(ELK4)to the dihydrofolate reductase(DHFR)enhancer.In vitro VM formation and invasion of OSCC cells were assessed using Matrigel-based tube formation and Transwell assays,respectively.Results:Elevated expression of VM-related genes predicts unfavorable prognosis in OSCC patients.High-dimensional weighted gene co-expression network analysis(hdWGCNA)identified epithelial subcluster C4 as most strongly associated with VM and metastasis.Three co-expression modules within this subcluster exhibited significant positive correlations with both phenotypic traits.Among the 30 eigengenes from the three modules,DHFR emerged as a key regulator of VM and metastasis.Knockdown or inhibition of DHFR significantly suppressed VM formation and invasion in OSCC cells.Mechanistically,ELK4 activated DHFR transcription through direct binding to its enhancer.DHFR overexpression rescued VM and invasion impairment induced by ELK4 knockdown.Conclusion:DHFR was a pivotal enhancer-regulated gene driving VM and metastasis in OSCC.ELK4 directly binds to DHFR enhancer regions to activate its transcription,thereby promoting these malignant phenotypes.These findings identified the ELK4/DHFR axis as a promising therapeutic target for anti-angiogenic intervention in OSCC.
文摘Over the past ten years,numerous papers have been published on the use of indocyanine green(ICG)fluorescence in liver surgery for hepatocellular carcinoma(HCC).There are many different applications.The first involves targeting superficial tumors in patients with macronodular cirrhosis and an irregular liver surface.In a minimally invasive setting,the lack of tactile feedback on the hepatic surface makes detecting subcapsular HCC with ultrasound alone challenging.ICG fusion images can mimic the tactile feedback of the hand and act as an ultrasound booster.ICG fluorescence can be used to evaluate tumor residues after minimally invasive thermal ablation.ICG fluorescence imaging can also be used to identify the grade of HCC early on and evaluate the microinvasive component.
文摘BACKGROUND Hepatocellular carcinoma(HCC)is a major type of liver cancer worldwide.In advanced stages,portal vein tumor thrombosis(PVTT)and jaundice are common,whereas obstructive jaundice(OJ)is relatively rare.Both conditions markedly reduce survival and increase therapeutic complexity.Recently,hepatic artery infusion chemotherapy(HAIC)in combination with targeted immunotherapy has shown promise for advanced HCC.CASE SUMMARY We report a 47-year-old male with advanced HCC complicated by PVTT and OJ,who was admitted with marked jaundice of the skin and sclera.Imaging revealed a large hepatic mass(14.5 cm×11.3 cm)in the right lobe with associated portal vein tumor thrombus.The tertiary bile duct was only mildly dilated,making percutaneous transhepatic cholangiography drainage infeasible.The patient underwent reduced-dose HAIC,which resulted in significant tumor shrinkage and marked reduction in serum bilirubin.This improvement enabled sequential treatment with lenvatinib and camrelizumab.After six cycles,both liver function and alphafetoprotein levels improved.The patient achieved a progression-free survival of 20 months and an overall survival of 29 months.CONCLUSION HAIC can treat high-bilirubin HCC with PVTT and OJ,allowing for subsequent targeted immunotherapy.

文摘Post-translational modifications(PTMs)regulate the occurrence and development of cancer,and lactylation modification is a new form of PTMs.Recent studies have found that lactic acid modification can regulate the immune tolerance of cancer cells.The classical theory holds that prostate apoptosis response-4(PAR-4)is a tumor suppressor protein.However,our recent research has found that PAR-4 has a biological function of promoting cancer in hepatocellular carcinoma(HCC),and our analysis shows that PAR-4 can be modified of lactic acid.These research evidences suggest that PAR-4 lactylation modification may drive immune tolerance in HCC.Therefore,inhibiting PAR-4 lactylation modification is very likely to increase the sensitivity of HCC to immunotherapy.

文摘Background:Hepatocellular carcinoma(HCC)is one of the leading causes of cancer-related mortality worldwide.This study aimed to identify key genes involved in HCC development and elucidate their molecular mechanisms,with a particular focus on mitochondrial function and apoptosis.Methods:Differential expression analyses were performed across three datasets—The Cancer Genome Atlas(TCGA)-Liver Hepatocellular Carcinoma(LIHC),GSE36076,and GSE95698—to identify overlapping differentially expressed genes(DEGs).A prognostic risk model was then constructed.Cysteine/serine-rich nuclear protein 1(CSRNP1)expression levels in HCC cell lines were assessed via western blot(WB)and quantitative reverse transcription polymerase chain reaction(qRT-PCR).The effects of CSRNP1 knockdown or overexpression on cell proliferation,migration,and apoptosis were evaluated using cell counting-8(CCK-8)assays,Transwell assays,and flow cytometry.Mitochondrial ultrastructure was examined by transmission electron microscopy,and intracellular and mitochondrial reactive oxygen species(mROS)levels were measured using specific fluorescent probes.WB was used to assess activation of the c-Jun N-terminal kinase(JNK)/p38 mitogen-activated protein kinase(MAPK)pathway,and pathway dependence was examined using the ROS scavenger N-Acetylcysteine(NAC)and the JNK inhibitor SP600125.Results:A six-gene prognostic model was established,comprising downregulated genes(NR4A1 and CSRNP1)and upregulated genes(CENPQ,YAE1,FANCF,and POC5)in HCC.Functional experiments revealed that CSRNP1 knockdown promoted the proliferation of HCC cells and suppressed their apoptosis.Conversely,CSRNP1 overexpression impaired mitochondrial integrity,increased both mitochondrial and cytoplasmic ROS levels,and activated the JNK/p38 MAPK pathway.Notably,treatment with NAC or SP600125 attenuated CSRNP1-induced MAPK activation and apoptosis.Conclusion:CSRNP1 is a novel prognostic biomarker and tumor suppressor in HCC.It exerts anti-tumor effects by inducing oxidative stress and activating the JNK/p38 MAPK pathway in a ROS-dependent manner.These findings suggest that CSRNP1 may serve as a potential therapeutic target in the management of HCC.
文摘BACKGROUND Intrathyroidal thymic carcinoma(ITC)is a rare malignant epithelial tumour of thymic origin occurring within the thyroid.Histologically,it resembles thymic carcinoma,with squamous cell carcinoma being the most common subtype,and immunohistochemical staining typically exhibits features consistent with thymic neoplasms.CASE SUMMARY We report the case of a 68-year-old woman who presented with a left-sided neck mass of one year’s duration.And the neck lump had been gradually enlarging over the course of a year,reaching the size of a goose egg within six months.Thyroid ultrasound revealed a normally sized thyroid gland.A 3.9 cm×3.4 cm×2.7 cm hypoechoic lesion with irregular echogenicity was observed outside the capsule of the lower pole of the left lobe.The mass exhibited regular morphology,well-defined margins,and close adherence to the thyroid’s lower pole.Microscopic examination revealed two distinct tumour cell populations:Squamous cell carcinoma and small cell carcinoma.Immunohisto-chemical staining demonstrated divergent differentiation-one population was positive for cluster of differentiation 5 and cluster of differentiation 117,supporting thymic origin,while the other exhibited neuroendocrine differentiation with synaptophysin and chromogranin A positivity.At eight months postoperatively,the patient remained recurrence-free on chemotherapy.CONCLUSION Based on these findings,the patient was diagnosed as ITC with both squamous cell and small cell carcinoma components.To date,nearly 100 cases of ITC have been reported in the literature.However,no prior reports of ITC exhibiting both squamous cell and small cell carcinoma components.This case report provides information on the microscopic morphological features of ITC with both squamous cell and small cell carcinoma components,which can help pathologists to expands the understanding of the pathological spectrum of the disease.
