Chemotherapy often induces oral ulcerative mucositis (OUM) in patients with cancer, characterized by severe painful inflammation. Mouth-washing with the Japanese herbal medicine hangeshashinto (HST) ameliorates chemotherapy-induced OUM in patients with colorectal cancer. Previously, we demonstrated that HST decreased interleukin 1β-induced prostaglandin E2 production in human oral keratinocytes (HOKs) and OUM-induced mechanical or spontaneous pain in rats. However, HST effects on tissue repair functions in HOKs remain unclear. Here, we examined the effects of HST on scratch-induced wound healing in vitro and in vivo. In vitro, HST enhanced wound healing mainly through scratch-induced HOK migration. Screening of the seven constituent medicinal herbs and their major components revealed that Scutellaria root, processed ginger, and Glycyrrhiza components mainly induced the scratch-induced HOK migration. Pharmacokinetic analyses indicated that the active ingredient concentrations in rat plasma following oral HST administration were below the effective doses for HOK migration, suggesting direct effects of HST in OUM. Mitogen-activated protein kinase and C-X-C chemokine receptor 4 inhibitors significantly suppressed HST-induced HOK migration. Moreover, HST enhanced tissue repair in our OUM rat model. Thus, HST likely enhanced OUM tissue repair through oral keratinocyte migration upon MAPK and CXCR4 activation and may be useful in patients with cancer-associated OUM.

日本草药 Hangeshashinto 可以增强口腔角质形成细胞的迁移,从而促进化疗引起的口腔溃疡性粘膜炎的愈合。



化疗经常会引起癌症患者的口腔溃疡性粘膜炎(OUM),其特征是严重的疼痛性炎症。使用日本草药 Hangeshashinto (HST) 漱口可改善结直肠癌患者化疗引起的 OUM。此前,我们证明 HST 可以减少人口腔角质形成细胞 (HOK) 中白介素 1β 诱导的前列腺素 E2 的产生,以及 OUM 诱导的大鼠机械性或自发性疼痛。然而,HST 对 HOK 组织修复功能的影响仍不清楚。在这里,我们在体外和体内研究了 HST 对划痕诱导的伤口愈合的影响。在体外,HST 主要通过划痕诱导的 HOK 迁移来增强伤口愈合。通过对7种药材及其主要成分的筛选发现,黄芩、炮制生姜和甘草成分主要诱导划痕诱导的HOK迁移。药代动力学分析表明,口服 HST 后大鼠血浆中的活性成分浓度低于 HOK 迁移的有效剂量,表明 HST 对 OUM 具有直接影响。丝裂原激活蛋白激酶和 CXC 趋化因子受体 4 抑制剂显着抑制 HST 诱导的 HOK 迁移。此外,HST 增强了我们的 OUM 大鼠模型的组织修复。因此,HST 可能通过 MAPK 和 CXCR4 激活后口腔角质形成细胞迁移来增强 OUM 组织修复,并且可能对癌症相关 OUM 患者有用。
