OBJECTIVES: Investigating the protective effect of naringenin (NAR) on the osteogenic potential of human periodontal ligament stem cells (hPDLSCs) under oxidative stress and its related mechanisms. METHODS: The oxidative damage model of hPDLSCs was established using hydrogen peroxide (H₂O₂) andthe hPDLSCs were treated with different concentrations of NAR and 0.5 μmol/L forkhead box protein O-1 (FOXO1) inhibitor AS1842856. After that, the cell counting kit-8 (CCK8) was used to determine the optimal concentrations of H₂O₂ and NAR. The alkaline phosphatase (ALP) staining and real time fluorescent quantitative reverse transcription polymerase chain reaction (qRT-PCR) were employed to assess the expression of ALP, runt-related transcription factor 2 (RUNX2) and osteocalcin (OCN) in hPDLSCs of each group. The enzyme-linked immunosorbent assay (ELISA) and 2',7'-dichlorofluorescin diacetate (DCFH-DA) staining were utilized to evaluate the expression of reactive oxygen species (ROS), malondialdehyde (MDA) and lactate dehydrogenase (LDH) in hPDLSCs. Meanwhile, qRT-PCR and western blot were used to detect the expression levels of FOXO1 and β-catenin, both are pathway related genes and proteins. RESULTS: H₂O₂ exposure led to an increase in oxidative damage in hPDLSCs, characterized by a rise in intracellular ROS levels and increased expression of MDA and LDH (P<0.05). At the same time, the osteogenic differentiation ability of hPDLSCs decreased, as evidenced by lighter ALP staining and reduced expression levels of osteogenic differentiation-related genes ALP, RUNX2 and OCN (P<0.05). Co-treatment with NAR alleviated the oxidative damage in hPDLSCs, enhanced their antioxidant capacity, and restored their osteogenic ability. The FOXO1 inhibitor AS1842856 downregulated the expression of β-catenin (P<0.05) and significantly diminished both the antioxidant effect of NAR and its ability to restore osteogenesis (P<0.05). CONCLUSIONS NAR can enhance the antioxidant capacity of hPDLSCs by activating the FOXO1/β-catenin signaling pathway within hPDLSCs, thereby mitigating oxidative stress damage and alleviating the loss of osteogenic capacity.

Objective Methyltransferase 3(METTL3)mediated N6-methyladenosine(m6A)methylation modifica-tion of transient receptor potential cation channel subfamily M member 7(TRPM7)regulates ferroptosis and malig-nant progression in cervical cancer(CESC).Methods Totally 40 patients with cervical cancer were collected.Cer-vical cancer tissues and adjacent normal tissues(≥3 cm from the edge of the tumor tissue)were sampled at opera-tion and then divided into experimental group and control group,respectively.RT-qPCR and Western blot were used to detect the differences in TRPM7 mRNA and protein expression between the two groups.TRPM7-interfering cell lines were constructed to investigate the effects of TRPM7 on CESC cells.Cell proliferation and apoptosis were assessed using 5-ethynyl-2'-deoxyuridine(EdU)assay and flow cytometry,respectively.Transwell chamber assays were employed to evaluate cell invasion and migration capabilities.The levels of ferroptosis in CESC cells were measured using kits for reactive oxygen species(ROS),malondialdehyde(MDA),glutathione(GSH),and Fe2+.Bioinformatics tools were utilized to predict methyltransferases associated with TRPM7.The interaction between METTL3 and TRPM7 was examined through RNA immunoprecipitation(RIP)and methylated RNA immunoprecip-itation quantitative PCR(Me-RIP qPCR).The effect of METTL3 on the stability of TRPM7 expression was assessed using actinomycin D assay.Results TRPM7 was highly expressed in CESC tissue and cells.Knockdown of TRPM7 significantly inhibited cell proliferation,promoted cell apoptosis,suppressed cell migration and invasion capabilities,and enhanced ferroptosis levels(P＜0.05).Bioinformatics predictions suggested that METTL3 might act as a methyltransferase for TRPM7.Interference with METTL3 gene expression significantly reduced TRPM7 pro-tein levels,decreased TRPM7 m6A modification levels,and impaired TRPM7 gene stability(P＜0.05).Conclusions METTL3 regulates CESC proliferation,apoptosis,migration,invasion,and ferroptosis by m6A meth-ylation modification of the TRPM7 gene.

It provides a detailed description of the guideline adaptation process and reporting content, which will significantly enhance the rigor, transparency, and standardization of guideline adaptations. This paper interprets and analyzes the 34 items on the checklist, with the aim of providing reference for guideline adapters to standardize the reporting process.

Liver transplantation, the only effective treatment for end stage liver disease, is characterized by complicated surgery, long surgery time, and high trauma. Patients may experience a variety of difficulties following surgery, including infection, abdominal bleeding and rejection, all of which directly affect the quality of rehabilitation. Enhanced Recovery After Surgery (ERAS), a novel perioperative management strategy, can effectively promote postoperative recovery of patients and has been extensively implemented in various fields of surgery. However, there are no scientific and universal ERAS protocols in the fields of liver transplantation in China. The first Consensus Recommendations of Enhanced Recovery for Liver Transplantation was issued by the International Liver Transplantation Society in December 2022, offering recommendations about ERAS strategies for liver transplantation recipients who receive deceased and living organ donations, and for living donors of liver transplantation. This paper provides a detailed interpretation of the key points to offer a practical reference for domestic liver transplantation perioperative ERAS management.
