Objective To explore the application of plasma 7 microRNA (miR7) testing in the differential diagnosis of very early-stage hepatocellular carcinoma (HCC). Methods This study is a multicenter real-world study. Patients with single hepatic lesion (maximum diameter≤2 cm) who underwent plasma miR7 testing at Zhongshan Hospital, Fudan University, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Anhui Provincial Hospital, and Peking University People’s Hospital between January 2019 and December 2024 were retrospectively enrolled. Patients were divided into very early-stage HCC group and non-HCC group, and the clinical pathological characteristics of the two groups were compared. The value of plasma miR7 levels, alpha-fetoprotein (AFP), and des-gamma-carboxy prothrombin (DCP) in the differential diagnosis of very early-stage HCC was evaluated using receiver operating characteristic (ROC) curves and area under the curve (AUC). In patients with both negative AFP and DCP (AFP＜20 ng/mL, DCP＜40 mAU/mL), the diagnostic value of plasma miR7 for very early-stage HCC was analyzed. Results A total of 64 528 patients from 4 hospitals underwent miR7 testing, and 1 682 were finally included, of which 1 073 were diagnosed with very early-stage HCC and 609 were diagnosed with non-HCC. The positive rate of miR7 in HCC patients was significantly higher than that in non-HCC patients (67.9% vs 24.3%, P＜0.001). ROC curves showed that the AUCs for miR7, AFP, and DCP in distinguishing HCC patients from the non-HCC individuals were 0.718, 0.682, and 0.642, respectively. The sensitivities were 67.85%, 43.71%, and 44.45%, and the specificities were 75.70%, 92.78%, and 83.91%, respectively. The pairwise comparison of AUCs showed that the diagnostic efficacy of plasma miR7 detection was significantly better than that of AFP or DCP (P＜0.05). Although its specificity was slightly lower than AFP and DCP, the sensitivity was significantly higher. Among patients negative for both AFP and DCP, miR7 maintained an AUC of 0.728 for diagnosing very early-stage HCC, with 67.82% sensitivity and 77.73% specificity. Conclusions Plasma miR7 testing is a potential molecular marker with high sensitivity and specificity for the differential diagnosis of small hepatic nodules. In patients with very early-stage HCC lacking effective molecular markers (negative for both AFP and DCP), miR7 can serve as a novel and effective molecular marker to assist diagnosis.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

OBJECTIVE To investigate the effect of Jianpi Yangzheng(JPYZ)formula regulating tumor-associated macrophage(TAM)exosomes on anoikis in gastric cancer and its mechanism.METHODS TAM model was established by inducing human mononuclear THP-1 cells in vitro;M0,TAM and TAM+JPYZ formula exosomes were extracted by ultracentrifugation and co-incuba-ted with gastric cancer cells.Flow cytometry was used to detect the effect of exosomes in each group on anoikis in gastric cancer cells.A BALB/c transplanted tumor mouse model was constructed,and the expression level of apoptotic proteins in transplanted tumors was detected by Western blot.Label-free mass spectrometry proteomics and bioinformatics were used to analyze the differential proteins in gastric cancer cells before and after intervention;Western blot and qPCR experiments were used to detect the expression level of dif-ferential protein isocitrate dehydrogenase 1(IDH1),and ubiquitination experiments were used to detect the ubiquitination level of IDH1;kits were used to detect the levels of α-ketoglutarate(α-KG),NADPH/NADP+,glutathione(GSH/GSSG)and reactive oxy-gen species(ROS)content.RESULTS The anoikis rate of gastric cancer cells was reduced after TAM exosomes intervention(P<0.05,P<0.01),while it was significantly increased after TAM+JPYZ exosomes intervention(P<0.05,P<0.01).In the in vivo mouse experiment,the ratio of Cleaved Caspase-3/Caspase-3 in the tumor of the TAM exosome group was reduced(P<0.05),while the ra-tio was significantly increased after TAM+JPYZ exosome intervention(P<0.05).Proteomic analysis showed that IDH1 was significant-ly different after intervention,and was related to tricarboxylic acid cycle metabolism.Compared with the M0 group,the IDH1 ubiquiti-nation level of gastric cancer cells in the TAM group with exosome intervention was increased,the levels of α-KG,NADPH/NADP+and GSH/GSSG were significantly increased,and the ROS content was reduced(P<0.05),while TAM+JPYZ exosomes could reverse the above phenomenon.CONCLUSION JPYZ Formula can regulate TAM exosomes to cause ubiquitin degradation of IDH1 in gas-tric cancer cells,reduce the level of tricarboxylic acid cycle metabolism in gastric cancer cells,promote ROS accumulation,induce anoikis in gastric cancer,and thus inhibit the development of gastric cancer.

Objective To elucidate the effect of curcumol on hepatic stellate cell iron death and epithelial-mesenchymal transition(EMT),and to investigate the molecular mechanism of its anti-liver fibrosis effect.Methods A model of hepatic stellate cell activation was constructed using normal cultured hepatic stellate cells in vitro,and the cells were divided into blank group and experimental-L,-M,-H groups.The blank group was given DMEM complete culture solution for normal culture;the experimental-L,-M,-H groups were given DMEM complete culture solution containing 12.5,25.0 and 50.0 mg·L-1 curcumol for 48 h of intervention.The effects of curcumol on the proliferation of hepatic stellate cells was observed by CCK-8.The expression levels of glutathione peroxidase 4(GPX4)and solute carrier family 7 member 11(SLC7A11)were detected by Western blot.The expression levels of E-cadherin and N-cadherin were detected by immunofluorescence.Results The cell proliferation rates of the experimental-M,-H groups and blank group were(68.97±5.61)％,(61.91±4.40)％and(118.07±10.01)％;the relative expression levels of GPX4 were 0.37±0.04,0.28±0.03 and 0.58±0.05;the relative expression levels of SLC7A11 were 0.38±0.04,0.28±0.03 and 0.60±0.05;E-cadherin levels were 6.76±1.09,9.57±1.73 and 2.05±0.72;N-cadherin levels were 5.66±0.66,3.44±0.78 and 10.37±0.66.The differences of above indicators were statistically significant between the blank group and the experimental-M,-H groups(P＜0.05,P＜0.01).Conclusion Curcumol promotes iron death in hepatic stellate cells,thereby inhibiting hepatic stellate cell EMT,which may be its molecular mechanism to prevent and treat liver fibrosis.

Objective To explore the role of Panax notoginseng saponins(PNS)in regulating the expression of sortilin and ATP-binding cassette transporter A1(ABCA1)in macrophages,and the effect of PNS on inhibiting formation of foam cells and the potential mechanism of PNS adjusting sortilin expression and cholesterol metabolism.Methods The macrophages were divided into five groups as follows:group A(only added with cell culture),group B(transfected with negative control lentivirus),group C(transfected with lentivirus-mediated sortilin overexpression),group D(transfected with lentivirus-mediated sortilin overexpression+60 μg·mL-1PNS),group E(transfected with lentivirus-mediated sortilin overexpression+10 μmol·L-1 mitogen-activated protein kinase kinase(MEK)inhibitor PD98059+60 μg·mL-1 PNS).The protein contents of sortilin,ABCA1,extracellular signal-regulated kinase(ERK)and phosphorylated-ERK(p-ERK)were evaluated with Western blot.All the cells in five groups were cultured with 50 μg·mL-1ox-LDL to form foam cells.The lipid in macrophages was investigated with red O assay.Results The relative expression levels of sortilin protein were 1.00±0.08,0.91±0.15,2.28±0.13,1.62±0.09 and 2.01±0.08;the relative expression levels of ABCA1 protein were 1.00±0.01,0.92±0.07,0.29±0.04,0.66±0.09 and 0.44±0.07;the ratios of p-ERK/ERK protein were 1.00±0.09,0.92±0.05,1.03±0.12,2.00±0.12 and 1.64±0.14;the contents of lipid in macrophages were(4.82±2.19)％,(6.70±0.88)％,(44.56±4.15)％,(27.66±3.25)％and(41.67±5.45)％.Except the ratios of p-ERK/ERK,the other parameters between group C and group A were statistically significant difference(all P＜0.01).Meanwhile,there were also statistically significant difference between group D and group C as well as group D and group E(P＜0.05,P＜0.01).Conclusion PNS inhibits the lipid accumulation in macrophages through upregulating ABCA1 and downregulating sortilin,and ERK signaling pathway may be as one of important mechanisms influencing the expression of sortilin and ABCA1 mediated by PNS.

In this study, we investigated the anti-inflammatory effect and mechanism of tilianin in lipopolysaccharide (LPS)-induced RAW264.7 cells. The cell viability was detected by cell counting kit-8 (CCK-8) assay. The content of tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6) were detected by enzyme-linked immuno sorbent assay (ELISA) kits. The content of nitric oxide (NO) was assayed by Griess reagent method. The level of intracellular reactive oxygen species (ROS) was detected by 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) fluorescent probe. The protein levels of Toll like receptor 4 (TLR4), myeloid differentiation primary response gene 88 (Myd88), nuclear factors κB p65 (NF-κB p65), phosphorylated nuclear factor κB p65 (p-NF-κB p65), nuclear factor κB inhibitory protein α (IκBα) and phosphorylation nuclear factor κB inhibitory protein α (p-IκBα) were detected by Western blot. The mRNA and protein levels of NLRP3, pro-IL-1β, pro-IL-18 and pro-caspase-1 were detected by qRT-PCR and Western blot. Immunofluorescence staining was used to detect the nuclear translocation of NF-κB p65. The effect of tilianin on the TLR4/Myd88/NF-κB signaling pathway was further validated by using the TLR4 signaling inhibitor restatorvid (TAK242). The results showed that tilianin significantly reduced the levels of TNF-α, IL-6 and NO in the supernatant of RAW264.7 cells and decreased the content of intracellular ROS. Tilianin reduced the levels of TLR4, Myd88, p-NF-κB p65 and p-IκBα protein and nuclear translocation of NF-κB p65. Tilianin could reduce the protein levels of NLRP3, pro-IL-1β, pro-IL-18 and pro-caspase-1. Tilianin significantly inhibited the mRNA levels of NLRP3 and pro-IL-1β. The above research results indicated that tilianin could significantly alleviate the LPS-induced inflammatory response in RAW264.7 cells and its mechanism might be related to downregulate the TLR4/Myd88/NF-κB signaling pathway to inhibit NLRP3 inflammasome.

OBJECTIVE To investigate the correlation between gene polymorphisms and adverse drug reaction （ADR） and demands of opioids， aiming to guide personalized opioid analgesic therapy. METHODS The existing evidence-based medical data were adopted to identify gene loci related to the efficacy and ADR of opioid analgesics and select highly relevant single nucleotide polymorphism （SNP） for a clinical case-control study. The study cohort was divided into two evaluation groups： ADR assessment and drug demand assessment. The ADR assessment group included 254 cancer pain patients and was subdivided into the trial subgroup （with ADR） and the control subgroup （without ADR） based on the presence or absence of ADR following opioid usage； the two subgroups included 126 and 128 patients， respectively. The drug demand assessment group included a total of 120 cancer pain patients， who were divided into trial subgroup （equivalent to a daily dose of oral morphine ≥100 mg） and control subgroup （equivalent to a daily dose of oral morphine ＜100 mg） based on the different daily doses of opioid analgesics， with 60 patients in each subgroup. Polymorphism detection of SNP loci in these patients was performed using fluorescence in situ hybridization. SPSS 21.0 software and SNPStats genetic models were employed to compare genetic testing results between subgroups and conduct correlation analyses， aiming to evaluate the association of the selected SNP loci with opioid ADR and drug demand inclinical real-world cases. RESULTS The strongly correlated SNP loci identified were CYP2D6*10（rs1065852，C＞T）， CYP3A5*3（rs776746，A＞G），ABCB1（rs1045642，C＞T）and OPRM1（rs1799971，A＞G）. Genetic testing results indicated that the allele frequency distributions of these SNP loci conformed to Hardy-Weinberg equilibrium. Correlation analysis revealed that in the ADR assessment group， compared with control subgroup， the proportion of patients in trial subgroup with the AA genotype of OPRM1 （rs1799971， A＞G） was significantly higher （P＜0.05）； in the drug demand assessment group， compared with control subgroup， the proportion of patients in trial subgroup with the CC+CT genotype of ABCB1 （rs1045642， C＞T） was significantly higher （P＜0.05）. CONCLUSIONS The AA genotype of OPRM1 （rs1799971， A＞G） is associated with the occurrence of ADR following oxycodone use. Patients with the CC+ CT genotype of ABCB1（ rs1045642， C＞T） require higher doses of opioid analgesics.

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.
