| 1 | Sini powder ameliorates the inflammatory response in rats with stress-induced non-alcoholic fatty liver disease by inhibiting the nuclear factor kappa-B/pyrin domain-containing protein 3 pathway显示文摘OBJECTIVE: To evaluate the effectiveness of Sini powder for the treatment of non-alcoholic fatty liver disease(NAFLD) in rats and the molecular mechanisms involved.METHODS: A rat model of stress-induced NAFLD was established by a combination of long-term tethering and feeding of a high-fat, high-calorie diet. These rats were then intragastrically administered with either simvastatin, Sini powder, or vehicle for 1 week. The body mass and field test scores for each group were recorded weekly. Serum aspartate aminotransferase and alanine aminotransferase activities, and triglyceride, total cholesterol,and free fatty acid concentrations were measured.Liver tissue histopathology was examined on hematoxylin and eosin-stained paraffin sections and oil red O-stained frozen sections. The hepatic m RNA expression of nuclear factor kappa-B(NF-κB),NOD-, LRR-, and pyrin domain-containing protein 3(NLRP3), apoptosis-associated speck-like protein containing CARD(ASC), and caspase-1 were measured by reverse transcription-polymerase chain reaction(RT-PCR). The hepatic protein concentrations of NF-κB and NLRP3, ASC, caspase-1, interleukin-1β(IL-1β), interleukin-6(IL-6), and the serum concentrations of IL-1β and IL-6 were measured by enzyme-linked immunosorbent assay.RESULTS: Compared with the Blank group, rats in the Compound model group showed significant pathologic manifestations of NAFLD, and the expression of NF-κB, NLRP3, ASC, caspase-1, IL-1βand IL-6 were significantly higher(all P < 0.01). Both simvastatin and Sini powder significantly ameliorated the NAFLD pathology and the abnormal expression of NF-κB, NLRP3, ASC, caspase-1, IL-1β, and IL-6(all P < 0.01).CONCLUSION: Sini powder inhibits the inflamma-tory response in rats with NAFLD, which is mediated by NF-κB/NLRP3, IL-1β, and IL-6, reduces the effects of psychological stress, and improves lipid metabolism. Therefore, Sini powder may be effective for the treatment of stress-related NAFLD through multiple mechanisms. | Mu Jie Cheng Fafeng Wang Qingguo Wang Xueqian Zhu Wenxiang Ma Chongyang Yin Xiangjun Ren Beida Lian Yajun Du Xin Zhang Haixia Liu Shuling Zhang Shuang | 2020 | Journal of Traditional Chinese Medicine2020，40，2： | 9 |
| 2 | Possible mechanisms underlying treatment of Alzheimer’s disease with Traditional Chinese Medicine: active components, potential targets and synthetic pathways of Bulao Elixir显示文摘OBJECTIVE: To elucidate the mechanisms underlying the treatment of Alzheimer’s disease(AD) with Traditional Chinese Medicine(TCM), by examining the active components, potential targets and synthetic pathways of Bulao Elixir(BLE).METHODS: The Absorption, Distribution, Metabolism, Excretion(ADME)/Toxicology(T) calculation was used to screen the active components of Bulao Elixir. Based on the TCM Systems Pharmacology Analysis Platform(TCMSP database) and a text mining tool(GoPubMed database), we predicted and screened the active components of Bulao Elixir and its therapeutic targets for AD. Using the Database for Annotation, Visualization and Integrated Discovery(DAVID), we obtained the targets for AD. Cytoscape software was used to establish a network map of the active component-target and target-pathway of Bulao Elixir. Gene function, related biological processes and signaling pathways were analyzed using the DAVID database.RESULTS: Twelve active components were selected from 196 components of Bulao Elixir. Among 2209 targets, 102 effective targets were selected, and 30 important targets were identified via matching with the disease targets. After further analysis, 14 core targets were identified. Enrichment analysis revealed that most of these important targets were involved in multiple biological processes, including apoptosis, inflammatory reactions, and cell regulation cycles. The synthetic pathways for AD treatment were identified after analyzing and confirming the relevant pathways, providing potentially useful information for diagnosis and treatment methods for AD.CONCLUSION: The current study elucidated the potential treatment mechanisms of Bulao Elixir in AD using network pharmacology, providing a foundation for further clarification of its treatment targets. | Ren Beida Cheng Fafeng Wang Xueqian Wan Yuxiang Ji Wenting Du Xin Zhang Shuang Liu Shilling Ma Chongyang Xiong Yiliang Hao Gaoting Wang Qingguo | 2020 | Journal of Traditional Chinese Medicine2020，40，3： | 4 |
| 3 | Qinzhi Zhudan formula improves memory and alleviates neuroinflammation in vascular dementia rats partly by inhibiting the TNFR1-mediated TNF pathway显示文摘Objective: The Qinzhi Zhudan formula(QZZD) exhibits a prominent therapeutic effect in the treatment of vascular dementia(VaD). This study combined a network pharmacology approach and experimental validation to identify the underlying biological mechanism of QZZD against VaD.Methods: Male Wistar rats received bilateral common carotid artery occlusion(BCCAO) surgery, and after4 weeks of intragastric administration of QZZD, the therapeutic effect was assessed using the Morris water maze test and cerebral blood flow(CBF) assessment. Hematoxylin and eosin staining, Nissl staining, and electron microscopy were used to measure the histopathological changes in the neurons of rats. The effect of QZZD treatment on hippocampal neurotransmitters was assessed by high-performance liquid chromatography with electrochemical detection and liquid chromatography mass spectrometry.Immunofluorescence was used to observe VaD-induced microglia activation. The inflammatory cytokine levels were assessed by enzyme linked immunosorbent assay. Western blot was used to examine the TNFR1-mediated TNF pathway, which was screened out by network pharmacology analysis.Results: QZZD treatment alleviated pathological changes and neuronal damage in VaD rats and attenuated their cognitive impairment. In addition, QZZD increased CBF and the expression of acetylcholine and 5-hydroxytryptamine in the hippocampal region. Notably, QZZD inhibited microglial activation and the expression of IL-6 and TNF-a. Network pharmacology and western blot indicated that QZZD inhibited the levels of TNFR1, NF-κBp65, p-ERK, TNF-a, and IL-6, which are related to the TNFR1-mediated TNF signaling pathway.Conclusion: QZZD clearly improved learning and memory function, reduced brain pathological damage,elevated CBF and hippocampal neurotransmitter levels, and alleviated neuroinflammation of VaD rats partly by inhibiting the TNFR1-mediated TNF pathway, indicating its potential value in the clinical therapy of VaD. | Shuling Liu Fafeng Cheng Beida Ren Wenxiu Xu Congai Chen Chongyang Ma Xiaole Zhang Feifei Tang Qingguo Wang Xueqian Wang | 2022 | Journal of Traditional Chinese Medical Sciences2022，9，3： | 0 |
