Abstract
Chemotherapy-induced oral mucositis (COM) is a common adverse effect of cancer chemotherapy. Several clinical studies reported that repetitive use of mouthwashes containing 2.5-6.25% Hangeshashinto (HST), a Kampo formula, relieves COM, but the effect is insufficient. To solve this problem, we produced an oral ointment of 12% HST extract (considered quantitatively equivalent to 20% commercially available HST), which will increase the local concentrations of its active ingredients and prolong the contact time with COM. In this study, we evaluated the pharmaceutical properties (spreadability and stability) of HST oral ointment. In addition, its safety (oral mucosal irritation) and therapeutic effects on 5-fluorouracil-induced oral mucositis were evaluated in male Syrian hamsters. The HST ointment showed good spreadability and stability for more than 8 weeks at 4 °C. In the oral mucosal irritation test, topical application of HST ointment (0.2 g) three times per day for 14 days had no adverse effect on the oral mucosa of hamsters. In hamsters treated with 5-fluorouracil (60 mg/kg) twice, COM was induced by a submucosal injection of 5% acetic acid into the cheek pouch. When HST ointment (50 µg) was topically applied to the mucositis area once per day for 12 days, the area and macroscopic score of mucositis were significantly decreased, and the depth of the wound tended to be reduced compared with the lactose ointment-treated control animals. These findings suggest that HST oral ointment shows good properties in spreadability, stability, and safety, and elicits a therapeutic effect in an animal model of COM.

Abstract
OBJECTIVE How could we transfer knowledge about healing plants from other cultures? We analyzed the results of literature search in two exemplary fields-oral mucositis and polyneuropathy. MATERIALS AND METHODS In both systematic searches of existing literature, we found 57 studies investigating 68 plants from different traditional cultures (16 Western Medicine, 14 Persian Medicine, 9 Japanese, 10 Chinese, and 8 other sources). We analyzed studies regarding their ingredient plants and reproducibility in relation to the system of origin. RESULTS Western and Persian Medicine trials investigate single plants, whereas Japanese and Chinese trials focus on mixtures and decoctions. European folk medicine knows of only 50% of plants used in both Asian cultures. The used ingredients and dosages were reproducible in all analyzed trials except TCM studies. CONCLUSIONS Herbal knowledge has been transferred from all folk medicines worldwide. However, Western oncologists should be aware that Traditional Chinese Medicine herbs are still a black box of knowledge for us until today.

Abstract
Purpose Hangeshashinto (TJ-14), a Kampo medicine comprising seven types of herbs, has been used in Japan to alleviate the side effects associated with anticancer drug treatments. However, the pharmacological effects of this medicine currently remain unclear. The present study aimed to demonstrate the efficacy of TJ-14 against anticancer drug-induced stomatitis, the pain associated with which may have a negative impact on mastication and swallowing. Methods Mucositis was induced in Sprague-Dawley rats by cancer chemotherapy. Changes in body weight, stomatitis grades, histopathological scores, and oral bacterial counts were examined among TJ-14-treated, saline-treated, and Control (no treatment) rats. In vitro studies, including cell proliferation and wound healing assays, using epidermal keratinocyte and fibroblast cell lines were conducted. Results The local application of TJ-14 exerted strong antibacterial effects and attenuated oral chemotherapy-induced stomatitis in rats. TJ-14 also increased the viability and invasion of epidermal keratinocytes and fibroblasts. Conclusion The present results demonstrated the potential of TJ-14 to attenuate chemotherapy-induced stomatitis.

Abstract
PURPOSE Oral mucositis is a common, painful side effect of cancer treatment-be it locoregional (e.g. irradiation) or systemic (e. g. chemotherapy). Phytotherapy is often used by patients to alleviate symptoms. However, knowledge on which medical plants are recommended by literature about Traditional European Medicine (TEM), their effect(s) on symptoms and their efficacy is severely lacking. Therefore, we developed a novel approach to assess traditional knowledge of herbals used in TEM and searched the online databases for studies reporting effects of these plants. METHODS At first, online research did not yield a satisfying number of studies (MESH terms: "mucositis" OR "stomatitis" AND "herbal" OR "herbal medicine"). Trials were labelled by the country conducting the study. In parallel, we compiled a list of 78 plants recommended for treating oral mucositis by screening 14 books on TEM. Then, a "hit list" of the plants most often mentioned was composed and used further for a second online investigation using the Latin plant designations as MESH term. Studies of both online searches were pooled for analysis. RESULTS There is a gap between traditional knowledge and trials investigating medical plants used by TEM. Overall, herbal remedies alleviate oral mucositis and especially, gingivitis well. There is good evidence for using Matricaria recutita L., Salvia officinalis L., Calendula officinalis L. and Thymus spp. L. for treating oral mucositis. CONCLUSION Clinical trials investigating medical plants known in TEM are rare. However, following our research strategy, we could extrapolate four plants with good evidence for alleviating symptoms of oral mucositis and gingivitis.

Abstract
BACKGROUND Oral ulcerative mucositis causes severe pain during eating and speaking, resulting in poor quality of life for patients with cancer undergoing chemoradiotherapy. Recently, some basic and clinical studies demonstrated that hangeshashinto, a traditional Japanese herbal medicine, alleviated oral ulcerative mucositis-induced pain. Here, we review a recently revealed pain mechanism underlying oral ulcerative mucositis in a preclinical rat model and the pharmacological analgesic effect of hangeshashinto. HIGHLIGHT In a rat model of experimentally induced oral ulcerative mucositis, the mucosal surface of the ulcerative region is damaged, which increases oral bacterial loading in the mucosa and prostanoid production. Chemotherapeutic drugs exaggerate the pathological condition and cause severe pain. The pain-related TRP channels, TRPV1, TRPA1, and/or TRPV4, mediate spontaneous and mechanical pain in oral ulcerative mucositis models. Swab application of hangeshashinto had a prolonged localized analgesic effect on oral ulcerative mucositis, even in a chemotherapy-treated oral ulcer model. Two ingredients of hangeshashinto, gingerol and shogaol, strongly inhibit voltage-activated sodium channels (though they have agonistic effects on TRPV1 and TRPA1), which confers hyposensitivity to the oral mucosa. Their analgesic effects on oral ulcerative mucositis are accompanied by accelerated delivery of drugs (other saponin-containing herbal extracts) into the ulcerative region. CONCLUSION Elucidation of the pain mechanism of oral ulcerative mucositis and analgesic mechanism of hangeshashinto will allow identification of novel therapeutic approaches against oral ulcerative mucositis-induced pain in patients. The traditional Japanese herbal medicine hangeshashinto is a reliable drug with supporting scientific evidence.

Abstract
Chemotherapy is nowadays the main treatment of human cancers. Chemotherapeutic agents target rapidly dividing cancer cells to suppress tumor progression, however, their non-specific cytotoxicity often leads to significant side effects that might be intolerable to cancer patients. Multi-component herbal products have been used for thousands of years for the treatment of multiple human diseases. This study aims to systematically summarize and evaluate the experimental and clinical evidences of the efficacy of multi-component herbal products in improving chemotherapy-induced side effect. Literature was retrieved from PubMed database and evaluated based on the side effects described. Multi-component herbal products were found to be effective in ameliorating the neurotoxicity, gastrointestinal toxicity, hematological toxicity, cardiotoxicity, hepatotoxicity and nephrotoxicity. Both experimental and clinical evidences were found, indicating the potential of applying multicomponent herbal products in the clinical treatment of chemotherapy-induced side effects. However, the lack of mechanistic and pharmacokinetic studies, inconsistency in product quality, as well as insufficient clinical evidence suggested that more investigations are urgently necessary. In all, our review shed light on the potential of using multi-component herbal products in the clinical management of chemotherapy-induced toxicity and side effects. We also discussed the potential threats of natural products for cancer treatment and compared the advantages of using herbs to conventional chemical drugs.

Abstract
JC-001 is a Chinese medicine that has been used to treat liver disease; however, its significance in cancer treatment has not been characterized. In this study, we used an immunocompetent tumor model to characterize the antitumor activity of JC-001. A total of 48 Hepa 1-6 tumor-bearing C57BL/6 mice were randomly grouped into 4 groups and treated with H2O or JC-001 via oral administration. After hepatoma cell lines, including HepG2, Hep3B, SK-Hep-1, and Hepa 1-6, underwent 96 hours of JC-001 treatment, a low cytotoxic effect was observed. In contrast, no direct cytotoxic effect of JC-001 on a normal human liver cell line, THLE-3, was observed under the same incubation conditions. Using a murine tumor model, we found that tumor growth could be inhibited by JC-001 in C57BL/6 mice but not in immunodeficient mice. Histopathological analysis of tumors from C57BL/6 mice revealed immune cell infiltration in tumors from the JC-001-treated group, as observed by hematoxylin and eosin staining; in addition, Ki67, hypoxia-inducible factor-1-α, and high mobility group box 1 expression levels were suppressed in the tumors. Both the coculture assay and murine spleen mRNA quantitative PCR analyses demonstrated that JC-001 could suppress Th17 immunity. Our data suggest that JC-001 is a Chinese medicine with low cytotoxicity that can significantly suppress tumor growth by immune regulation. This herbal remedy has great potential for future clinical application in hepatoma therapy.

Hangeshashinto (TJ-14) prevents radiation-induced mucositis by suppressing cyclooxygenase-2 expression and chemotaxis of inflammatory cells. Clin Transl Oncol 2017; 19:1329-1336.

Abstract
PURPOSE Radiation-induced oral mucositis is the most common side effect of radiotherapy in head and neck cancer; however, effective modalities for its prevention have not been established. In this study, we evaluated the effectiveness of Hangeshashinto (TJ-14), a Japanese herbal medicine, for preventing radiation-induced mucositis and elucidated its effect on inflammatory responses, including inflammatory cell chemotaxis and cyclooxygenase-2 (COX2) expression, in an animal model. METHODS Syrian hamsters, 8-9 weeks old, were enrolled in this study. Animals were irradiated with a single 40 Gy dose to the buccal mucosa. Hamsters freely received a treatment diet mixed with 2% TJ-14 or a normal diet daily. The therapeutic effect was determined based on the visual mucositis score, body weight, and histological examination of infiltrated neutrophils and COX2 expression. RESULTS TJ-14 significantly reduced the severity of mucositis. The percentage with severe mucositis (score ≥3) was 100% in the untreated group and 16.7% in the TJ-14 group (P < 0.05). There was no difference in body weight change between the groups; however, weight gain in the untreated group tended to be suppressed compared to that in the TJ-14 group during the peak period of mucositis. In addition, TJ-14 inhibited the infiltration of neutrophils and COX2 expression in irradiated mucosa (P < 0.05). CONCLUSIONS TJ-14 reduced the severity of mucositis in an animal model by suppressing the inflammatory response. Because TJ-14 is inexpensive and its safety is established, it is a promising candidate for the standard treatment of radiation-induced mucositis in cancer patients.

Abstract
The traditional Japanese herbal medicine hangeshashinto (HST) has beneficial effects for the treatment of oral ulcerative mucositis (OUM) in cancer patients. However, the ingredient-based mechanism that underlies its pain-relieving activity remains unknown. In the present study, to clarify the analgesic mechanism of HST on OUM-induced pain, we investigated putative HST ingredients showing antagonistic effects on Na+ channels in vitro and in vivo. A screen of 21 major ingredients using automated patch-clamp recordings in channel-expressing cells showed that [6]-gingerol and [6]-shogaol, two components of a Processed Ginger extract, considerably inhibited voltage-activated Na+ currents. These two ingredients inhibited the stimulant-induced release of substance P and action potential generation in cultured rat sensory neurons. A submucosal injection of a mixture of [6]-gingerol and [6]-shogaol increased the mechanical withdrawal threshold in healthy rats. In a rat OUM model, OUM-induced mechanical pain was alleviated 30min after the swab application of HST despite the absence of anti-bacterial and anti-inflammatory actions in the OUM area. A swab application of a mixture of [6]-gingerol and [6]-shogaol induced sufficient analgesia of OUM-induced mechanical or spontaneous pain when co-applied with a Ginseng extract containing abundant saponin. The Ginseng extract demonstrated an acceleration of substance permeability into the oral ulcer tissue without an analgesic effect. These findings suggest that Na+ channel blockage by gingerol/shogaol plays an essential role in HST-associated analgesia of OUM-induced pain. This pharmacological mechanism provides scientific evidence supporting the use of this herbal medicine in patients suffering from OUM-induced pain.

AIMS Sinonasal mucosal malignant melanoma (SNMMM) is a rare disease. The aim of the present study was to describe its clinicopathological features and prognosis in a Chinese population. METHODS Data on 83 SNMMM patients were collected and analyzed. A survival analysis was performed using the Kaplan-Meier method and a log-rank test. RESULTS The most common presenting symptoms of SNMMM were nasal obstruction, epistaxis, and bloody rhinorrhea. Histopathologically, 38 cases (45.78%) were amelanotic. Five cell types (epithelioid, undifferentiated, plasmacytoid, spindle, and clear) were identified. Positive staining for human melanoma black-45 and Melan-A was diagnostic of SNMMM. Advanced age, multiple tumor sites, and amelanotic-type SNMMM indicated a worse outcome (p = 0.008, p = 0.009, and p = 0.013, respectively). Neither adjuvant therapy nor the tumor stage was associated with overall survival. CONCLUSIONS SNMMM is an uncommon disease with atypical symptoms. Its histopathological appearance is variable, especially in the amelanotic type. Thus, immunohistochemistry is important in the diagnosis, and it should be performed according to the histology.

Abstract
OBJECTIVE Recent studies have demonstrated that mouthwash made with the traditional Japanese medicine hangeshashinto exhibits anti-inflammatory action and alleviates oral mucositis scores, including pain complaints, in patients undergoing chemoradiotherapy. However, no study has demonstrated the mechanism underlying how hangeshashinto provides pain relief in oral ulcers. DESIGN The analgesic effects on pain-related behaviors following the topical application of hangeshashinto were evaluated in an oral ulcer rat model treated with acetic acid using recently developed methods. Indomethacin, the representative anti-inflammatory agent, was intraperitoneally administered. The tissue permeability of the oral mucosa was histologically evaluated after applying the fluorescent substance FluoroGold. RESULTS The topical application of hangeshashinto in ulcerative oral mucosa suppressed mechanical pain hypersensitivity over 60 min, without any effects on healthy mucosa. The same drug application also inhibited oral ulcer-induced spontaneous pain. Indomethacin administration failed to block the mechanical pain hypersensitivity, though it did largely block spontaneous pain. Topical anesthesia with lidocaine showed hyposensitivity to mechanical stimulation in healthy mucosa. In the ulcer regions in which the oral epithelial barrier was destroyed, deep parenchyma was stained with FluoroGold, in contrast to healthy oral mucosa, in which staining was limiting to the superficial site. CONCLUSIONS Hangeshashinto leads to long-lasting analgesic effects, specifically in the ulcer region by destroying the epithelial barrier. Hangeshashinto alleviates oral ulcer-induced pain in inflammation-dependent and/or independent manner.
