Alzheimer's disease （AD） is a common type of dementia， primarily characterized by cognitive and behavioral impairments as well as deficits in learning and memory. The progression of AD has imposed a significant economic burden on society and families. However， its exact pathogenesis has not yet been fully elucidated. Currently， available therapeutic drugs are limited and are often accompanied by serious adverse effects. Traditional Chinese medicines （TCMs） and their extracts are mostly natural products and possess advantages such as multi-pathway regulation and relatively few adverse reactions. Experimental studies have shown that TCMs exhibit great potential in the prevention and treatment of AD. For example， Huanglian Jieduang， Danggui Shaoyaosan， Kaixin San， Liuwei Dihuangwan， Buyang Huanwutang， as well as Ginseng Radix et Rhizoma， Astragali Radix， Uncariae Ramulus cum Uncis， Coptidis Rhizoma， Gardeniae Fructus， Ginkgo Folium， Salviae Miltiorrhizae Radix et Rhizoma， and Curcumae Longae Rhizoma， can reduce β-amyloid deposition， inhibit excessive Tau protein phosphorylation， restore mitochondrial function， alleviate oxidative stress， suppress neuroinflammation and apoptosis， repair synaptic function， and improve gut microbiota. This article mainly summarizes the effects of several TCMs and compound prescriptions on AD， aiming to provide a reference for subsequent TCM-based treatment of AD.

Objective:To investigate the short-term and long-term effects of competency-oriented BOPPPS combined with scenario simulation teaching model on team emergency rescue skills training for healthcare professionals in Xizang.Methods:Forty-four healthcare professionals who participated in team emergency rescue training at Bianba People's Hospital from May 2022 to May 2023 were selected as study subjects. The BOPPPS combined with scenario simulation teaching model was applied in the clinical teaching of acute myocardial infarction. Before the training, the post competency was assessed using the Self-Directed Learning Instrument. The short-term teaching effects were evaluated using skill assessment and questionnaire after the training, and the long-term teaching effects were evaluated using the same questionnaire after six months.Results:Post-training skill assessment scores of the trainees were (50.45±6.68) for skill operation, (7.80±0.97) for humanistic communication, and (16.28±1.52) for team cooperation, which were significantly higher than pre-training scores ( P<0.05). Among self-directed learning abilities, "I enjoy finding answers to questions" was positively correlated with the humanistic communication scores, and "I can connect new knowledge with my personal experiences" was negatively correlated with skill operation scores ( P<0.05). The score of long-term emergency rescue skill improvement (4.27) was significantly higher than that after the training in the short term (3.98) ( P<0.05), while there were no significant decreases in career confidence and team collaboration ability ( P>0.05). Conclusions:The post competency-oriented BOPPPS combined with scenario simulation teaching model contributes to improving the team emergency rescue skills of healthcare professionals in Xizang, stabilizing their career confidence, and stimulating their self-learning ability. It is suitable to promote this teaching model in the clinical skills training of healthcare professionals in Xizang.

Alzheimer's disease(AD)is the most common neurodegenerative disorder worldwide,characterized primarily by cognitive impairment and memory dysfunction.Its pathological mechanisms involve the toxic accumulation of amyloid β-protein(Aβ),hyperphosphorylation of Tau protein leading to neurofibrillary tangles,mitochondrial dysfunction,synaptic impairment,cholinergic system dysfunction,neuroinflammation,and oxidative stress.Current clinical treatments for AD include acetylcholinesterase inhibitors and N-methyl-D-aspartate antagonists,which can improve cognitive function but fail to slow disease progression and often have side effects.Research indicates that traditional Chinese medicine(TCM)may regulate the phosphatidylinositol 3-kinase/protein kinase B(PI3K/AKT)signaling pathway,promoting neuronal survival,inhibiting neuroinflammation,reducing oxidative stress,preventing apoptosis,and decreasing Aβ deposition,thus improving the symptoms of AD.This review summarizes the mechanisms by which individual TCM components,extracts,and formulas may regulate the PI3K/AKT pathway in the treatment of AD,with the aim of providing a theoretical foundation for the application of TCM in AD therapy.

Alzheimer's disease (AD) is the major form of dementia in the elderly and is closely related to the toxic effects of microglia sustained activation. In AD, sustained microglial activation triggers impaired synaptic pruning, neuroinflammation, neurotoxicity, and cognitive deficits. Accumulating evidence has demonstrated that aberrant expression of deubiquitinating enzymes is associated with regulating microglia function. Here, we use RNA sequencing to identify a deubiquitinase YOD1 as a regulator of microglial function and AD pathology. Further study showed that YOD1 knockout significantly improved the migration, phagocytosis, and inflammatory response of microglia, thereby improving the cognitive impairment of AD model mice. Through LC-MS/MS analysis combined with Co-IP, we found that Myosin heavy chain 9 (MYH9), a key regulator maintaining microglia homeostasis, is an interacting protein of YOD1. Mechanistically, YOD1 binds to MYH9 and maintains its stability by removing the K48 ubiquitin chain from MYH9, thereby mediating the microglia polarization signaling pathway to mediate microglia homeostasis. Taken together, our study reveals a specific role of microglial YOD1 in mediating microglia homeostasis and AD pathology, which provides a potential strategy for targeting microglia to treat AD.

Objective To investigate the effects of fractionated low-dose ionizing radiation (LDIR) on the ferroptosis in human bronchial epithelial (HBE) cells as well as the associated differentially expressed genes (DEGs), biological processes, and signaling pathways. Methods HBE cells were exposed to different single doses of X-ray irradiation (0, 25, 50, 75, and 100 mGy) for 24, 48, and 72 h, respectively. The change in cell viability was detected by MTT assay. Cells were irradiated with 0, 25, 50, and 100 mGy X-rays 5 times, with 48 h between each irradiation and a dose rate of 50 mGy/min. Cells were harvested 24 h after irradiation for the measurement of the expression of ferroptosis-related genes SLC7A11 and GPX4 at the mRNA and protein levels, cellular iron content, and the expression of FTH1 and FTL mRNAs. High-throughput sequencing was used to screen for the DEGs in each dose group, followed by Gene Ontology-Biological Process (GO-BP) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and Gene Set Enrichment Analysis (GSEA). Results Compared with the control group, single-dose LDIR significantly increased cell proliferation at 75 mGy after 24 h (P < 0.05), at 50, 75, and 100 mGy after 48 h (P < 0.05), and at 75 and 100 mGy after 72 h (P < 0.05). Compared with the control group, at the end of the fifth fractionated LDIR, SLC7A11 and GPX4 mRNAs decreased at all doses (P < 0.05), SLC7A11 protein decreased at all doses, GPX4 protein decreased at 25 and 100 mGy, iron content increased at all doses, and FTH1 and FTL mRNAs decreased at all doses (P< 0.05). Sequencing analysis identified 248, 30, and 291 DEGs and 10, 2, and 9 ferroptosis-associated genes at the three doses compared to the control. Gene Ontology-Biological Process analysis showed that DEGs were mainly enriched in biological processes such as response to lipids, cell death, and response to unfolded proteins. Kyoto Encyclopedia of Genes and Genomes analysis showed that DEGs were mainly enriched in the JAK-STAT signaling pathway, lipids and atherosclerosis, ferroptosis, protein processing in the endoplasmic reticulum, and FoxO signaling pathway. Gene set enrichment analysis showed that DEGs were mainly enriched in ferroptosis, fatty acid degradation, and glutathione metabolism. Conclusion Fractionated low-dose radiation induced ferroptosis in HBE cells, and DEGs were predominantly enriched in biological processes and signaling pathways related to inflammation, ferroptosis, and endoplasmic reticulum stress.
