This study aims to investigate the effects of astragalus polysaccharide (APS) on diabetic retinopathy through the SHH-Gli1-AQP1 pathway. The anti-type 2 diabetes mellitus (T2DM) targets of APS were identified through comprehensive searches of drug and disease-related databases. A protein-protein interaction network was then constructed, followed by GO and KEGG enrichment analyses.Molecular docking simulations were performed to evaluate the interactions of APS and metformin with Gli1 and AQP1. An in vivo T2DM rat model was established via streptozotocin (STZ) injection and treated with metformin and varying doses of APS for 12 weeks. Histological changes in retinal cells were assessed using H&E and PAS staining. The expression levels of AQP1, Gli1, and SHH in the retina were measured using immunohistochemistry, Western blotting, immunofluorescence, and ELISA. Additionally, mRNA expression of AQP1, Gli1, and SHH was quantified by RT-qPCR. Bioinformatic analyses indicated that Gli1 and AQP1, key components of the SHH-Gli1-AQP1 signaling pathway, may be associated with T2DM. Subsequent experiments demonstrated that the STZ-induced T2DM rats exhibited significant retinal damage, which was notably mitigated by both APS and metformin treatments. Furthermore, the SHH-Gli1-AQP1 signaling pathway was found to be overactivated in STZ-induced T2DM rats. Treatment with APS and metformin significantly reduced the elevated expression levels of SHH, Gli1, and AQP1. APS effectively inhibits retinal damage of STZinduced T2DM rats by restraining the SHH-Gli1-AQP1 signaling pathway.

Objective To explore the dietary nutrition status and nutritional intervention strategy of patients with Alzheimer’s disease (AD). Methods Among the 1 332 patients with AD diagnosed at Xijing Hospital from January 2021 to December 2023 were enrolled as the study subjects. The dietary intake data of patients were collected through questionnaire surveys and dietary reviews. During the study period, 30 patients did not complete the intervention due to withdrawal or loss of follow-up. Based on the actual number of people who completed the intervention, AD patients were randomly divided into intervention group (n=651, individualized nutritional intervention strategy) and control group (n=651, routine nutritional intervention), and both groups were intervened for 3 months. The cognitive function (MMSE score and MoCA score), nutritional status (MNA scale, NRS-2002 scale), and quality of life (GQOL-74) of the two groups of AD patients were compared to evaluate the effectiveness of the intervention strategies. Results A total of 1 332 questionnaires were distributed, and 1 302 valid questionnaires were finally recovered, with an effective recovery rate of 97.75% (1 302/1 332). The survey results showed that there were no statistical differences in baseline characteristics and dietary nutrition status between the two groups of AD patients before intervention (P>0.05). After nutritional intervention, the cognitive function, quality of life, and nutritional status of patients in the intervention group were significantly improved. The MMSE score, MoCA score, MNA score, and GQOL-74 score of the intervention group were significantly higher than those of the control group, while the NRS-2002 score was lower than that of the control group (P<0.05). Conclusion Nutritional intervention strategy has a significant effect on improving nutritional status, cognitive function, and quality of life of AD patients.

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.

AIM: To investigate the effects of agkis-trodon halys venom anti-tumor component (AHVAC-) on the biological behavior of gastric cancer MKN-28 cells. METHODS: Gastric cancer MKN-28 cells were treated with the experimental concentrations (5, 10, 15 μg/mL) of AHAVC- for 24 h. Cell proliferation and toxicity assay (cell counting kit-8, CCK-8) was used to detect the inhibition rates of the cells in different concentrations of AHVAC-. The migration ability of the cells was evaluated by wound-healing and Transwell assay. The apoptosis were observed by laser confocal microscopy with annexin V-mCherry/DAPI double staining, and the apoptosis rates were analyzed by flow cytometry with annexin V-FITC/PI double fluorescence staining. The protein level of Caspease-3 was determined by Western blot. RESULTS: Compared with normal control group, the results of AHVAC- concentration groups showed that with the increase of AHVAC- concentration, the proliferative activity of MN-28 cells decreased gradually (P<0.01), the cell migration ability decreased gradually (P<0.01), and the cell apoptosis rate increased (P<0.05). The expression of apoptosis-related protein Caspease-3 was up-regulated (P<0.01). CONCLUSION: AHVAC- inhibits proliferation and migration of gastric cancer MSN-28 cells and induces apoptosis.
