Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Objective: To determine the clinical efficacy and mechanism of Piwei Peiyuan Pill (PPP) combined with moxibustion for treating patients with chronic atrophic gastritis (CAG) with spleen and stomach weakness syndrome. Methods: Ninety-six CAG patients with spleen and stomach weakness syndrome who met the inclusion and exclusion criteria were enrolled at the Department of Spleen and Stomach Diseases of the Second Affiliated Hospital of Anhui University of Chinese Medicine from June 2022 to December 2023. The patients were randomly divided into a control, a Chinese medicine, and a combined group using a random number table method, with 32 cases in each group (two cases per group were excluded). The control group was treated with rabeprazole combined with folic acid tablets (both thrice daily), the Chinese medicine group was treated with PPP (8 g, thrice daily), and the combined group was treated with moxa stick moxibustion (once daily) on the basis of the Chinese medicine group for 12 consecutive weeks. Gastric mucosa atrophy in the three groups was observed before and after treatment. The gastric mucosal pathological score was evaluated. The Patient Reported Outcome (PRO) scale was used to evaluate the patients′ physical and mental health status and quality of life.An enzyme-linked immunosorbent assay was used to detect serum tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-4, IL-10, IL-37, and transforming growth factor (TGF)-β levels in each group. Real-time fluorescence PCR was used to detect the relative expression levels of signal transducer and activator of transcription 3 (STAT3) and mammalian target of rapamycin (mTOR) mRNA in each group. Western blotting was used to detect the relative expression levels of proteins related to the STAT3/mTOR signaling pathway, and the adverse drug reactions and events were recorded and compared. Results: There was no statistical difference in age, gender, disease duration, family history of gastrointestinal tumors, alcohol consumption history, and body mass index among the three groups of patients.The total therapeutic efficacy rates of the control, Chinese medicine, and combined groups in treating gastric mucosal atrophy were 66.67% (20/30), 86.67% (26/30), and 90.00% (27/30), respectively (P<0.05). Compared to before treatment, the pathological and PRO scale scores of gastric mucosa in each group decreased after treatment, and TNF-α, IL-1β, IL-37, and TGF-β levels decreased. The relative STAT3 and mTOR mRNA expression levels, as well as the relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels decreased (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the control group, the pathological score of gastric mucosa, PRO scale score, TNF-α, IL-1β, IL-37, TGF-β content, relative STAT3 and mTOR mRNA expression levels, and relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels in the Chinese medicine and combined groups after treatment were reduced (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the Chinese medicine group, the combined group showed a decrease in relative STAT3, mTOR mRNA expression levels, and STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels (P<0.05). Conclusion The combination of PPP and moxibustion may regulate the inflammatory mechanism of the body by inhibiting the abnormal activation of the STAT3/mTOR signaling pathway, upregulating related anti-inflammatory factor levels, downregulating pro-inflammatory factor expression, and increasing related repair factor expression, thereby promoting the recovery of atrophic gastric mucosa, reducing discomfort symptoms, and improving the physical and mental state of CAG patients with spleen and stomach weakness syndrome.

Objective: To explore the relationship between stigma and mental resilience in adolescent epilepsy patients and associated factors, so as to provide reference for future psychological intervention in adolescent patients with epilepsy. Methods: A total of 295 adolescent patients with epilepsy from Wuhan Mental Health Center were enrolled as participants from February 2021 to October 2024. The stigma was evaluated by Kilifi Stigma Scale for Epilepsy (KSSE), and psychological resilience was evaluated by Connor-Davidson Resilience Scale (CD-RISC). Associated factors of stigma and psychological resilience in adolescent patients with epilepsy were analyzed by multivariate Logistic regression analysis. Results: In the adolescent patients with epilepsy, KSSE score was (10.90±4.13) points, with 138 cases (46.78%) at low level, 154 cases (52.20%) at moderate level and 3 cases (1.02%) at high level. CD-RISC score was (50.19±5.97) points, there were 170 cases (57.63%) at low level and 125 cases (42.37%) at high level. Multivariate Logistic regression analysis showed that disease course >3 years ( OR =2.22), family history of epilepsy ( OR = 4.18) , monthly family income ≤5 000 yuan ( OR =2.05), single parent family ( OR =2.46) and middle and high stigma level ( OR = 1.72) had a higher risk on low level of mental resilience ( P <0.05). The course of disease >3 years ( OR =2.20), family history of epilepsy ( OR =3.54), general seizure ( OR =2.12), monthly family income ≤5 000 yuan ( OR =2.70), low level of mental resilience ( OR =2.03) of adolescent epilepsy patients showed a high risk on moderate high level of stigma ( P <0.05). Conclusions The stigma level is higher, while psychological resilience is lower in adolescent patients with epilepsy. Clinically, targeted intervention should be implemented based on related factors such as stigma in addescent patients with epilepsy.

AIM: To investigate the causal effects of ceramides on retinal vein occlusion(RVO)and elucidate their potential mediating mechanisms using Mendelian randomization(MR)analysis.METHODS: Genome-wide association study(GWAS)data for four ceramide species were utilized as exposures, and RVO GWAS data from the FinnGen database as the outcome. Additionally, GWAS data for 1 400 intermediate metabolites were analyzed to identify potential mediators in the ceramide-RVO pathway.RESULTS: Two ceramide species exhibited significant causal associations with RVO: ceramide(d40:1)[IVW OR(95% CI): 0.750(0.604-0.930), P<0.05] and ceramide(d42:2)[IVW OR(95% CI): 0.771(0.632-0.941), P<0.05], suggesting protective effects. Mediation analysis revealed that ceramide(d40:1)influenced RVO risk through metabolites including 3-methylxanthine, branched/straight-chain/cyclopropyl 10:1 fatty acids, glutamine, and hydroxypalmitoyl sphingomyelin. Similarly, ceramide(d42:2)acted via N-methylhydroxyproline, the same fatty acid group, N1-methyladenosine, and the leucine-to-N-palmitoyl-sarcosinate ratio.CONCLUSION: Ceramides(d40:1)and(d42:2)confer protection against RVO, partially mediated by specific metabolic pathways.
