The transition of cancer cells from epithelial state to mesenchymal state awarded hepatocellular carcinoma (HCC) stem cell properties and induced tumorigenicity, drug resistance, and high recurrence rate. Reversing the mesenchymal state to epithelial state by inducing mesenchymal-epithelial remodeling could inhibit the progression of HCC. Using high-throughput screening, chrysin was selected from natural products to reverse epithelial-mesenchymal transition (EMT) by selectively increasing CDH1 expression. The target identification suggested chrysin exerted its anti-HCC effect through covalently and specifically binding threonine 205 (Thr205) of alpha-enolase (ENO1). For the first time, we revealed that ENO1 bound β-catenin mRNA, and recruited YTHDF2 to identify the m6A modified β-catenin in the 3'-UTR region to degrade β-catenin mRNA. Eventually, the CDH1 gene expression was improved through the regulation of β-catenin mRNA. ENO1/β-catenin mRNA interaction might be a promising target for cellular plasticity reprogramming. Moreover, chrysin could mediate mesenchymal‒epithelial remodeling through increasing degradation of β-catenin mRNA by promoting the binding of ENO1 and β-catenin mRNA. To the best of our knowledge, chrysin is the first reported small molecule inducing β-catenin mRNA degradation through binding to ENO1. The water-soluble derivative of chrysin may be a natural product-derived lead compound for circumventing metastasis, recurrence, and drug resistance of HCC by mediating mesenchymal‒epithelial remodeling.

Colorectal inflammatory cancer transformation poses a major risk to patients with colitis. Patients with chronic intestinal inflammation have an approximately 2-3 folds increased risk of developing colorectal cancer (CRC). Unfortunately, there is currently no effective intervention available. Huangqin decoction (HQD), a well-known traditional Chinese medicine (TCM) formula, is frequently clinically prescribed for treating patients with colitis, and its active ingredients have effective antitumour efficacy. Nonetheless, the mechanism of HQD-mediated prevention of colorectal inflammatory cancer transformation remains unclear. A strategy integrating metagenomic, lipidomic, and messenger RNA (mRNA) sequencing analysis was used to investigate the regulatory effects of HQD on the gut microbiome, metabolism and potential mechanisms involved in colorectal inflammatory cancer transformation. Our study revealed that HQD suppressed colorectal inflammatory cancer transformation, which was associated with enhanced intestinal barrier function, decreased the inflammatory response, and regulation of the gut microbiome. Notably, cohousing experiments revealed that the transfer of the gut microbiome from HQD-treated mice largely inhibited the pathological transformation of colitis. Moreover, gut microbiome transfer from HQD-treated mice primarily resulted in the altered regulation of fatty acid metabolism, especially the remodeling of arachidonic acid metabolism, which was associated with the amelioration of pathological transformation. Arachidonic acid metabolism and the key metabolic enzyme arachidonic acid 12-lipoxygenase (ALOX12) were affected by HQD treatment, and no obvious protective effect of HQD was observed in Alox 12 ^-/- mice, which revealed that ALOX12 was a critical mediator of HQD protection against colorectal inflammatory cancer transformation. In summary, multiple omics analyses were applied to produce valuable data and theoretical support for the application of HQD as a promising intervention for the transformation of inflammatory CRC.

Traditional Chinese medicine (TCM) is an ancient medical system distinctive and effective in treating cancer, depression, coronavirus disease 2019 (COVID-19), and other diseases. However, the relatively abstract diagnostic methods of TCM lack objective measurement, and the complex mechanisms of action are difficult to comprehend, which hinders the application and internationalization of TCM. Recently, while breakthroughs have been made in utilizing methods such as network pharmacology and virtual screening for TCM research, the rise of machine learning (ML) has significantly enhanced their integration with TCM. This article introduces representative methodological cases in quality control, mechanism research, diagnosis, and treatment processes of TCM, revealing the potential applications of ML technology in TCM. Furthermore, the challenges faced by ML in TCM applications are summarized, and future directions are discussed.

Porcine epidemic diarrhea virus (PEDV) is an intestinal coronavirus that can cause porcine epidemic diarrhea, leading to diarrhea, vomiting, weight loss, and even death in piglets. Due to the diversity of PEDV strains, traditional vaccines are difficult to sustainably and effectively prevent and control PEDV. This article reviews the strategies and mechanisms of active substances in regulating intracellular signaling pathways, viral proteins, and microbial metabolites to enhance the host immune function against PEDV. It emphasizes the prevention of PEDV resistance and the potential harm of PEDV breaking through interspecies barriers to the human society, aiming to provide reliable theoretical support for the development of new antiviral drugs or vaccines.

AIM: To explore the clinical application effect of visual training equipment combined with conventional corrective treatment on children with ametropic amblyopia(AMA).METHODS: Prospective randomized control study. A total of 188 children(376 eyes)with AMA treated in our hospital from June 2021 to December 2022 were selected, and they were divided into two groups using a random number table. The conventional correction group(94 cases, 188 eyes)received conventional correction treatment, while the visual training group(94 cases, 188 eyes)received visual training equipment combined with conventional correction treatment, both lasted for 12 mo. The best corrected visual acuity, diopter, eye accommodation function, adverse reactions, amblyopia recurrence rates, and clinical efficacy were compared between the two groups at 6 and 12 mo after treatment.RESULTS:The two groups each had 8 cases(16 eyes)detached, the rate of loss to follow-up was 8.5%, and 86 cases(172 eyes)were included in each group. There were statistically significant differences in the best corrected visual acuity, diopter, amplitude of accommodation, accommodation facility and accommodative lag between the two groups of children before and after treatment(all P<0.05). The total effective rate of the visual training group(98.8%)was higher than that of the conventional correction group(91.9%; P<0.05). There was no statistically significant difference in the total effective rate of clinical efficacy between the two groups in different age groups and different degrees of amblyopia(all P>0.05). There was no statistically significant difference in the incidence of redness and swelling between the two groups(P>0.05). The recurrence rate of amblyopia in the visual training group(1.2%)was lower than that in the conventional correction group(8.1%; P<0.05).CONCLUSION: The combination of visual training equipment and conventional correction therapy has a significant clinical effect on children with AMA, which can effectively correct visual acuity, adjusting diopter and improve eye accommodation function, and recurrence rate of amblyopia is low and safety is high.

ObjectiveTo investigate the effect and molecular mechanism of exosomes derived from bone marrow mesenchymal stem cells（BMSC-exos） modified with Bushen Yisui capsule（BSYS）-containing serum on promoting the differentiation and maturation of OLN-93 oligodendrocytes by regulating miR-15b/Wnt signaling pathway. MethodsOLN-93 cells were divided into 5 groups， including the normal（NC） group， BMSC-exos group， BSYS-BMSC-exos group， BSYS-BMSC+LV-miR-15b-5p inhibitor-exos group， and BSYS-BMSC+LV-miR-15b-5p NC-exos group. DiR staining was used to observe the uptake of Exos by OLN-93 cells. The effective dosage of BSYS-BMSC-exos on OLN-93 cells was assessed by cell proliferation and activity assay（CCK-8）. Stable BMSCs lentiviral transfection strains were established to inhibit miR-15b-5p expression in both BMSCs and their exos， and transfection efficiency was verified by real-time fluorescent quantitative polymerase chain reaction（Real-time PCR） detection of miR-15b-5p. The expressions of 2′，3′-cyclic nucleotide 3′-phosphodiesterase（CNPase） and myelin proteolipid protein（PLP） in OLN-93 cells were detected by immunocytochemistry（ICC） and Western blot. The mRNA expressions of miR-15b-5p and Wnt3a in OLN-93 cells were detected by Real-time PCR， and the protein expression of Wnt3a was measured by Western blot. The expression levels of key molecules in the Wnt/β-catenin signaling pathway of OLN-93 cells， including glycogen synthase kinase（GSK）-3β， β-catenin， and T-cell specific transcription factor 4/transcription factor 7-like 2（TCF4/TCF7L2）， were measured by Real-time PCR and Western blot. ResultsDiR-labeled Exos were efficiently taken up by OLN-93 cells. The CCK-8 assay results indicated that 20 mg·L^-1 of BSYS-BMSC-exos exhibited the most significant effect in enhancing OLN-93 cell viability（P<0.01） and this dosage was selected for subsequent experiments. Following lentiviral transfection of BMSCs， Real-time PCR results revealed that miR-15b-5p was significantly suppressed in BMSCs（P<0.01）， and miR-15b-5p was also notably inhibited in BSYS-BMSC-exos（P<0.01）. ICC analysis further revealed an increase in the number of differentiated， mature CNPase and PLP-positive cells following BSYS-BMSC-exos treatment（P<0.01）. Western blot results demonstrated that the protein expression of CNPase and PLP was significantly enhanced with BSYS-BMSC-exos treatment（P<0.01）. Additionally， BSYS-BMSC-exos also increased the expression levels of miR-15b-5p and p-β-catenin proteins in OLN-93 cells， while decreased the mRNA and protein expressions of Wnt3a， as well as the mRNA expressions of β-catenin and TCF4/TCF7L2， and the protein expression level of p-GSK-3β（Ser9） was significantly reduced（P<0.05， P<0.01）. After the transfection of miR-15b-5p inhibitor into BSYS-BMSC-exos， the above effects were significantly diminished（P<0.05， P<0.01）. ConclusionBSYS-BMSC-exos facilitate the differentiation and maturation of OLN-93 cells， and its mechanism is related to the upregulation of miR-15b-5p in OLN-93 cells， which inhibits the expression of Wnt3a and thereby suppresses the Wnt signaling pathway.
