Objective To explore the action targets and related mechanisms of pogostemon cablin in the treatment of glioma based on network pharmacology and cellular experiments.Methods The active ingredi-ents and action targets of pogostemon cablin were collected by using databases such as the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)and the Traditional Chinese Med-icine Comprehensive Database(TCMID).The relevant targets of glioma were collected through databases such as Gene Cards and OMIM,and the network diagrams of"drug-target"and"disease-target"were estab-lished by using Cytoscape3.7.1 software.The intersection targets of pogostemon cablin for treating glioma were obtained and STRING database was used to analyzed,and their protein-protein interaction(PPI)net-work diagram was established.Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis on key targets were performed by using the DAVID database.In vitro cell experiments on key signaling pathways were conducted,U87 glioma cells were collected and divided into the control group(added to basic culture medium)and the 60,90,120 μg/mL pog-ostemon cablin groups(added to culture medium containing 60,90,and 120 μg/mL pogostemon cablin,respec-tively).CCK-8 assay and wound healing assay were used to detect the proliferation and migration ability of each group of cells,and the protein expression levels of mitogen activated protein kinase 1(MAPK1),recom-binant V-rel reticuloendotheliosis viral oncogene homolog A(RELA)phosphatidylinositol 3-kinase(PI3K),protein kinase B(Akt),phosphorylated-PI3K(p-PI3K),and phosphorylated-Akt(p-Akt)in each group of cells were detected by Western blot.Results A total of 94 main chemical constituents of pogostemon cablin were obtained.According to the screening conditions,9 effective active ingredients,239 drug target proteins,4 526 glioma related genes and 121 drug and disease common targets were identified.Protein interaction net-works discovered that Akt1,c-Jun N-terminal kinase(JUN),MAPK1,RELA,interleukin(IL)-6 and epider-mal growth factor receptor(EGFR)may be the key targets of pogostemon cablin in the treatment of glioma.GO function enrichment analysis identified 1 819 items in biological processes,109 items of cellular compo-nents and 216 items of molecular functions,which involved various aspects such as the positive regulation of the cellular metabolic process,the activity of protein homodimers,kinase activation,and membrane rafts.KEGG pathway enrichment analysis identified 181 related signaling pathways,involving anti-cancer,inflamma-tion,cell apoptosis,endocrine,immune regulation and so on,mainly including the PI3K/Akt pathway,ad-vanced glycation advanced glycation end products(AGE)/recepter for advanced glycation end products(RAGE)pathway,IL-6 pathway,and HIF-1 pathway,TNF pathway and so on.The in vitro experimental re-sults showed that compared with the control group,with the increase of the dose of the alcohol extract of pog-ostemon cablin,the cell activity decreased,the cell migration ability decreased,and the expression levels of MAPK1,RELA,p-PI3K and p-Akt proteins decreased(P＜0.05).Conclusion Pogostemon cablin can syner-gistically inhibit the development of glioma through multiple targets and pathways,and can suppress cell pro-liferation of U87 cells through the PI3K/Akt pathway.

Background:Ribosomal protein L22-like 1(RPL22L1)exerts regulatory effects on various malignant tumors such as lung cancer,prostate cancer,and cervical cancer.However,its role in colorectal cancer(CRC)remains unclear.Aims:To investigate the expression of RPL22L1 in CRC and its role in patients' prognosis and glucose metabolism of tumor cells.Methods:A total of 142 newly diagnosed CRC patients admitted to the Taizhou First People's Hospital from February 2022 to June 2024 were enrolled.The expression levels of RPL22L1 mRNA and protein were detected by quantitative real-time PCR and immunohistochemistry,respectively.The correlation between RPL22L1 expression and clinicopathological characteristics was analyzed.Kaplan-Meier survival analysis was used to evaluate the impact of RPL22L1 expression on the prognosis of CRC patients.RPL22L1 siRNA was transfected into SW480 cells to establish a low-expression cell model.Cell proliferation was assessed by CCK-8 assay,cell migration by Transwell chamber assay,and apoptosis by flow cytometry.Gene set enrichment analysis(GSEA)was performed to evaluate the effect of RPL22L1 on glucose metabolism of tumor cells.Results:The expression levels of RPL22L1 mRNA and protein were significantly higher in CRC tissues than in adjacent normal tissues(all P<0.05).The expression level of RPL22L1 mRNA was correlated with the TNM stage and carcinoembryonic antigen level of CRC(all P<0.05).Kaplan-Meier analysis showed that the cumulative survival rate of high RPL22L1 mRNA expression group was significantly lower than that of low-expression group(P=0.027).The expression level of RPL22L1 mRNA was significantly higher in SW480 cells than in normal intestinal epithelial cells(P<0.001).After inhibiting RPL22L1 expression,the proliferation and migration capacities of SW480 cells were significantly decreased(all P<0.05),the apoptosis rate was significantly increased(P=0.005),and the lactate level and relative glucose uptake level were significantly reduced(all P<0.05).GSEA indicated that RPL22L1 gene was associated with glycolysis/gluconeo-genesis(P=0.02).Conclusions:RPL22L1 is highly expressed in CRC and is associated with poor prognosis of patients,suggesting its potential as a molecular target for CRC therapy.Furthermore,RPL22L1 may promote the tumorigenesis and progression of CRC by modulating glucose metabolism.

The purpose of this study was to evaluate the application value of targeted next-generation sequencing(tNGS)for rapid detection of Mycobacterium tuberculosis.From September 2021 to October 2024,1 178 clinical samples from hospitalized pa-tients at the Non-tuberculous Mycobacteria Disease Diagnosis and Treatment Center of Guangzhou Chest Hospital were collected,in-cluding 272 sputum samples,871 broncho alveolar lavage fluid(BALF)samples,and 35 other samples.These samples were analyzed with tNGS and the liquid culture+DNA microarray chip method(referred to as the"culture identification method"),and the detection results between methods were compared.The numbers of Mycobacterium tuberculosis complex(MTBC)samples identified with tNGS and the culture identification method were 172 and 127,respectively,and the numbers of non-tuberculous mycobacteria(NTM)samples detected were 517 and 474,respectively.The detection rate of Mycobacterium was 56.88%with tNGS and was significantly lower(49.49%)with the culture identification method(χ2=13.27,P<0.05).For NTM identification,when sputum was used,the detection rate of tNGS was higher than that of the culture identification method(χ2=24.14,P<0.05).However,when BALF was used,no significant difference in detection rates was observed between tNGS and the culture identification method(χ2=3.97,P=0.06).When different sample types from the same patient were analyzed with tNGS for NTM,BALF was found to be a better choice than sputum(χ2=4.05,P<0.05).However,with the culture identification method,we observed no significant difference between sample types(χ2=2.72,P=0.10).Furthermore,both the MTBC and NTM sequences detected with tNGS were significantly higher in the culture-positive group than the culture-negative group.With increasing sequence numbers,the proportion of cases in the culture-positive group progressively rose,whereas an inverse trend was observed in the culture-negative group.With clinical diagno-sis as the reference standard,the sensitivity,specificity,and Kappa value of tNGS and the culture identification method in identifying mycobacterial diseases were 85.41%,91.32%,0.74 and 74.73%,93.15%,0.63,respectively.Compared with the culture identifica-tion method,tNGS for rapid detection of Mycobacterium exhibited excellent sensitivity,specificity and consistency,and its timeliness should help clinicians make precise individualized treatment plans earlier.
