[Current status of animal experiment report of acupuncture intervention in chronic fatigue syndrome based on ARRIVE guidelines and GSPC list].

OBJECTIVE: To analyze the current status of animal experiments of acupuncture in intervening chronic fatigue syndrome, so as to search formethods to improve the quality of animal experiment reports. METHODS: From the databases, such as CNKI, VIP, Wanfang, SinoMed, PubMed, Web of Science, Embase and Cochrane Library, the literature of animal experiment on acupuncture treatment for chronic fatigue syndrome was searched from January 1st, 2011 to April 2nd, 2022. Data were extracted according to the animal research reporting in vivo experiment (ARRIVE) guidelines 2.0 and gold standard publication checklist (GSPC), and statistical analysis was performed using Excel 2019. RESULTS: A total of 16 studies were finally included. The satis-faction rate of essential items in the ARRIVE guidelines 2.0 is 41.76%，while the satisfaction rate of recommended items is only 27.73% and of the GSPC is 25.89%. Out of 16 studies, 13 of them explained the reasons for animal exclusion in the experiment, 8 provided specific randomized methods, 8 described detailed information on animal species, strains, and quantities, 3 basically indicated that they had passed ethical review, 7 explained the limitations of the research. All 16 studies reported the main findings and elucidated their potential clinical or scientific value. CONCLUSION: Current animal studies on acupuncture in intervening the chronic fatigue syndrome are of certain limitation. Descriptions of multiple items are incomplete or missing, which prevents rea-ders from assessing reliability and authenticity of the animal experiment. It is recommended that in future research, experimental design, execution and report should be carried out according to the report guidelines for animal experiment to improve research quality.

Mechanism of Key Ingredient of Astragalus membranaceus on Lung Adenocarcinoma via PI3K/AKT Signaling Clarified by Utilizing Network Pharmacology Approach and Experimental Validation.

OBJECTIVE: To investigate the mechanism of the effect of Astragalus membranaceus (A. membranaceus) on lung adenocarcinoma at the molecular level to elucidate the specific targets according to the network pharmacology approach. METHODS: The active components of A. membranaceus and their potential targets were collected from the Traditional Chinese Medicine Systems Pharmacology Database. Lung adenocarcinoma-associated genes were acquired based on GeneCards, Online Mendelian Inheritance in Man (OMIM), PharmGKB, and Therapeutic Targets databases. The PI3K/AKT signaling pathway-related genes were obtained using Reactome portal. Networks of "ingredient-target" and "ingredient-target-pathway-disease" were constructed using the Cytoscape3.6.0 software. The relationships among targets were analyzed according protein-protein interaction (PPI) network. Finally, molecular docking was applied to construct the binding conformation between active ingredients and core targets. Cell counting kit 8 (CCK8) and Western blot assays were performed to determine the mechanism of the key ingredient of A. membranaceus. RESULTS: A total of 20 active components and their 329 targets, and 7,501 lung adenocarcinoma-related genes and 130 PI3K/AKT signaling pathway-related genes were obtained. According to Venn diagram and PPI network analysis, 2 mainly active ingredients, including kaempferol and quercetin, and 6 core targets, including TP53, MAPK1, EGF, AKT1, ERBB2, and EGFR, were identified. The two important active ingredients of A. membranaceus, kaempferol and quercetin, exert the therapeutic effect in lung adenocarcinoma partly by acting on the 6 core targets (TP53, MAPK1, EGF, AKT1, ERBB2, and EGFR) of PI3K/AKT signaling pathway. Expressions of potential targets in lung adenocarcinoma and normal samples were analyzed by using UALCAN portal and found that ERBB2 was overexpressed in lung adenocarcinoma tissues and upregulation of it correlated with clinicopathological characteristics. Finally, quercetin repressed viabilities of lung adenocarcinoma cells by targeting ERBB2 on PI3K/AKT signaling confirmed by CCK8 and Western blot. CONCLUSION: Our finding unraveled that an active ingredient of A. membranaceus, quercetin, significantly inhibited the lung adenocarcinoma cells proliferation by repressing ERBB2 level and inactivating the PI3K/AKT signaling pathway.

[Current state about researches on selection of experimental indexs mechanisms of acupuncture underlying improvement of chronic fatigue syndrome].

Acupuncture therapy is effective in the treatment of chronic fatigue syndrome (CFS) and has its own unique advantages. In the present paper, we reviewed the progress of experimental researches on the underlying mechanisms of acupuncture treatment of CFS in recent 10 years from: 1) regulating the immune system including the peripheral immune organ, immune cells and immune cytokines, proinflammatory and anti-inflammatory cytokines, and lowering the increase of positive rate of multiple mycoplasma infection; 2) regulating the neuroendocrine system including the hypothalamus-pituitary-adrenal axis and stress hormones, monoamine neurotransmitters, and opioid peptides; 3)raising the anti- oxidative stress ability by reducing malondiadehyde, and upregulating activities of antioxidant enzymes superoxide dismutase and glutathione peroxidase; and 4) regulating multiple cellular molecule signaling pathways revealed by genomic and proteomic technologies. In conclusion, acupuncture can relieve CFS through multiple ways and systems, which may provide some ideas for further studies on the biological mechanisms.
