Tuina alleviates neuropathic pain through regulate the activation of microglia and the secretion of inflammatory cytokine in spinal cord

Journal of traditional chinese Medicine 2024年第4期44卷 762-769页

作者： WU Zhiwei ZHU Qingguang KONG Lingjun SONG Pengfei ZHOU Xin GUO Guangxin ZHANG Shuaipan HE Tianxiang CHENG Yanbin FANG Min Yueyang Hospital of Integrated traditional chinese and Western Medicine Shanghai University of Traditional Chinese Medicine institute of Tuina Shanghai Institute of Traditional Chinese Medicine Shuguang Hospital Shanghai University of Traditional Chinese Medicine Department of Acupuncture and Tuina Shanghai University of Traditional Chinese Medicine

OBJECTIVE: To observe the analgesic effects of Tuina on neuropathic pain(NPP) and the underlying mechanisms. METHODS: Forty-eight Sprague-Dawley(SD) rats were assigned by random into three treatment groups: sham, chronic constriction injury(CCI), and Tuina. Each group contained sixteen rats. CCI model was generated by ligating the right sciatic nerve. Behavioral changes of CCI were assessed by the paw withdrawal threshold(PWT) and paw withdrawal latency(PWL). In addition, biochemical techniques such as immunofluorescence staining, enzyme-linked immunosorbent assay(ELISA) and Western blotting were used to profile levels of microglia activation and inflammatory factors in the spinal dorsal horn(SDH) of rats. Tuina(clockwise pressing and rubbing) was performed at Chengshan(BL57) to observe the analgesic effects on CCI rats and the underlying mechanisms. RESULTS: Rats with CCI experienced significant reduction in the PWT and PWL of the right hind paw relative to CCI group at day 3. Tuina treatment rescued this situation significantly on days 10 and 14. Besides, Iba-1, microglia M1 receptor CD68, tumor necrosis factor-α(TNF-α), and interleukin-1β(IL-1β) were higher in the right SDH for CCI group compared to the sham group on day 14. As expected, Tuina partially downregulated the CCI-induced overexpressed Iba-1, CD68, TNF-α, and IL-1β in the SDH of CCI model. CONCLUSION: Tuina induces a time-dependent cumulative analgesic effect in CCI rats by inhibiting the activation of microglia and the secretion of IL-1β and TNF-α in SDH.

From ancient wisdom to modern science:Gut microbiota sheds light on property theory of traditional chinese medicine

引用

Journal of Integrative Medicine 2024年第4期22卷 413-444页

The property theory of traditional chinese medicine(TCM) has been practiced for thousands of years,playing a pivotal role in the clinical application of TCM. While advancements in energy metabolism,chemical composition analysis, machine learning, ion current modeling, and supercritical fluid technology have provided valuable insight into how aspects of TCM property theory may be measured, these studies only capture specific aspects of TCM property theory in isolation, overlooking the holistic perspective inherent in TCM. To systematically investigate the modern interpretation of the TCM property theory from multidimensional perspectives, we consulted the chinese Pharmacopoeia(2020 edition) to compile a list of chinese materia medica(CMM). Then, using the Latin names of each CMM and gut microbiota as keywords, we searched the PubMed database for relevant research on gut microbiota and CMM. The regulatory patterns of different herbs on gut microbiota were then summarized from the perspectives of the four natures, the five flavors and the meridian tropism. In terms of the four natures, we found that warm-natured medicines promoted the colonization of specific beneficial bacteria,while cold-natured medicines boosted populations of some beneficial bacteria while suppressing pathogenic bacteria. Analysis of the five flavors revealed that sweet-flavored and bitter-flavored CMMs positively influenced beneficial bacteria while inhibiting harmful bacteria. CMMs with different meridian tropism exhibited complex modulative patterns on gut microbiota, with Jueyin(Liver) and Taiyin(Lung) meridian CMMs generally exerting a stronger effect. The gut microbiota may be a biological indicator for characterizing the TCM property theory, which not only enhances our understanding of classic TCM theory but also contributes to its scientific advancement and application in healthcare.
