To investigate whether Du-Huo-Ji-Sheng-Tang (DHJST) attenuate inflammation of RA related to lymphatic drainage function in vivo, we treated eight 3-month-old TNF-Tg mice with DHJST (12 g/kg) or the same volume of physiological saline once every day for 12 weeks, and 3-month-old WT littermates were used as negative control. After twelve weeks, we performed NIR-ICG imaging and found that DHJST increased the ICG clearance at the footpad and the pulse of efferent lymphatic vessel between popliteal lymph node and footpad. Histology staining at ankle joints showed that DHJST decreases synovial inflammation, bone erosion, cartilage erosion, and TRAP+ osteoclast area in TNF-Tg mice. Immunohistochemical staining by using anti-Lyve-1 and anti-podoplanin antibody showed that DHJST stimulated lymphangiogenesis in ankle joints of TNF-Tg mice. And zebrafish study suggested that DHJST promoted the formation of lymphatic thoracic duct. In conclusion, DHJST inhibits inflammation severity and promotes lymphangiogenesis and lymphatic drainage function of TNF-Tg mice.
为了研究独活寄生汤(DHJST)是否能减轻与淋巴引流功能相关的 RA 炎症,我们用 DHJST(12g/kg)或相同体积的生理盐水处理 8 只 3 月龄 TNF-Tg 小鼠,每天一次,持续 12 周,同时以 3 月龄 WT 同窝小鼠作为阴性对照。12 周后,我们进行 NIR-ICG 成像,发现 DHJST 增加了足底和腘窝淋巴结与足底之间的淋巴流出脉的 ICG 清除率。踝关节组织学染色显示,DHJST 可减少 TNF-Tg 小鼠的滑膜炎症、骨侵蚀、软骨侵蚀和 TRAP+破骨细胞面积。用抗 Lyve-1 和抗 podoplanin 抗体进行免疫组织化学染色显示,DHJST 可刺激 TNF-Tg 小鼠踝关节的淋巴管生成。斑马鱼研究表明,DHJST 可促进胸导管的形成。综上所述,DHJST 可抑制 TNF-Tg 小鼠的炎症严重程度,促进其淋巴管生成和淋巴引流功能。
