As a Chinese herbal medicine used in East Asia for thousands years, Cortex Magnoliae Officinalis (CMO) was observed to possess a protective effect against OH-induced DNA damage in the study. To explore the mechanism, the antioxidant effects and chemical contents of five CMO extracts were determined by various methods. On the basis of mechanistic analysis, and correlation analysis between antioxidant effects & chemical contents, it can be concluded that CMO exhibits a protective effect against OH-induced DNA damage, and the effect can be attributed to the existence of phenolic compounds, especially magnolol and honokiol. They exert the protective effect via antioxidant mechanism which may be mediated via hydrogen atom transfer (HAT) and/or sequential electron proton transfer (SEPT). In the process, the phenolic-OH moiety in phenylpropanoids is oxidized to the stable quinine-like form and the stability of quinine-like can be ultimately responsible for the antioxidant.

The protective effect of Naoxingtong (NXT) on rat cerebral microvascular endothelial cell (rCMEC) was investigated. rCMEC was injured in vitro by incubating for 4 hours at 100% NO in a hypoxia chamber. After treated with NXT-containing serum, the cellular viability rate (90.3%) was significantly elevated when compared with that of control group and the inhibitive rate of lactic dehydrogenase activity (9.2%) was far lower than the control group with dose-dependent effect. The results indicate that NXT can increase viability of rCMEC, and protect cell membrane from injury during hypoxia.

Effects of Naoxintong (NXT, a formula of Chinese Materia Medica)-containing serum on Nitrogen monoxide (NO) and calcitonin gene related peptide (CGRP) in rat cerebral microvascular endothelial cells (rCMEC) was investigated, rCMEC was injured in vitro by incubating for 4 hours at 100% NO in a hypoxia chamber. The results indicated that NXT could antagonize the reduction of NO and CGRP secreted by rCMEC during hypoxia, the effect of which was dose-dependent. After treated with NXT-containing serum at dosage of 5.0 - 30 and 50 -1.1 g/kg/U respectively, the amount of NO and CGRP secreted by rCMEC were remarkably increased during hypoxia in vitro.

[6]-Gingerol is known as the major bioactive constituent of ginger. In the study, it was observed to effectively protect against ${\bullet}OH$-induced DNA damage ($IC_{50}$ $328.60{\pm}24.41{\mu}M$). Antioxidant assays indicated that [6]-gingerol could efficiently scavenge various free radicals, including ${\bullet}OH$ radical ($IC_{50}$ $70.39{\pm}1.23{\mu}M$), ${\bullet}O_2{^-}$ radical ($IC_{50}$ $228.40{\pm}9.20{\mu}M$), $DPPH{\bullet}$radical ($IC_{50}$ $27.35{\pm}1.44{\mu}M$), and $ABTS{^+}{\bullet}$radical ($IC_{50}$ $2.53{\pm}0.070{\mu}M$), and reduce $Cu^{2+}$ ion ($IC_{50}$ $11.97{\pm}0.68{\mu}M$). In order to investigate the possible mechanism, the reaction product of [6]-gingerol and $DPPH{\bullet}$ radical was further measured using HPLC combined mass spectrometry. The product showed a molecular ion peak at m/z 316 $[M+Na]^+$, and diagnostic fragment loss (m/z 28) for quinone. On this basis, it can be concluded that: (i) [6]-gingerol can effectively protect against ${\bullet}OH$-induced DNA damage; (ii) a possible mechanism for [6]-gingerol to protect against oxidative damage is ${\bullet}OH$ radical scavenging; (iii) [6]-gingerol scavenges ${\bullet}OH$ radical through hydrogen atom ($H{\bullet}$) transfer (HAT) and sequential electron (e) proton transfer (SEPT) mechanisms; and (iv) both mechanisms make [6]-gingerol be oxidized to semi-quinone or quinone forms.

Objectives : This study was conducted to suggest new alternative methods to improve pharmacopuncture and Korean medicine research by analyzing the injection route, pharmacological effect, and status studies of Chinese herbal injections. Methods : 130 types of marketed and licensed Chinese herbal injection were searched from National Medical Products Administration (NMPA) of China. CNKI, PubMed, EMBASE, and the 2020 edition of the Chinese Pharmacopoeia were used to collect additional information. 'Herbal injection' and 'Chinese herbal injection' were used as keywords. All data were collected mainly on the treatment of Chinese herbal injection. But data which were not related to the relevant research or Chinese herbal injection were excluded. Results : Intramuscular injection accounted for more than half of the single injection route (51%). Acupoint and intramuscular injections accounted for 55% of dual injection routes. Acupoint, intravenous, and intramuscular injections accounted for the largest proportion (76%) of the multiple routes of injections. As for the pharmacological effect, injection for cardiovascular diseases accounted for 29%. About the number of raw herbal materials, single herbal material was the most common. Twelve intervention studies all tested intravenous injections, and half of them investigated cardiocerebrovascular diseases. All were given by intravenous injection. In the side effect section, the most common symptoms were nausea and vomiting. Conclusions : Through the results, it is expected to be used for research and development of new pharmacopuncture and herbal medicine.

Objectives The purpose of this study is to analyze studies about the effects of topical application of Chinese herbal medicine for allergic rhinitis within randomized controlled trials (RCT). Methods The search database includes KJTK (Korean Traditional Knowledge Portal), OASIS (Oriental Medicine Advanced Searching Integrated system), CNKI (China National Knowledge Infrastructure), PubMed, and EMBASE. We used the following key search terms: "allergic rhinitis", "traditional Chinese medicine", "traditional Korean medicine", "Chinese herbal medicine", "randomized controlled trial", "clinical study", "nasal spray", and "nasal drop" Results Five studies were selected for analysis. Three studies used nasal spray of Chinese herbal medicine and two studies used nasal drops of Chinese herbal medicine for the intervention. Frequently used herbs were Magnoliae Flos (辛夷), Scutellariae Radix (黃芩), Coptidis Rhizoma (黃連), and Astragali Radix (黃芪). For the outcome measures, studies used symptom score, questionnaire of Quality of Life, nasal airway resistance, or laboratory studies. From all 5 studies, it has been shown that topical application of Chinese herbal medicine was effective for improving symptoms of allergic rhinitis. Two out of five studies showed statistical difference between study group and control group. Conclusions This study shows that topical application of Chinese herbal medicine can improve symptoms of allergic rhinitis. Well-designed RCT studies with low risk of bias and studies with outcome measures for assessing the immunomodulatory effects are necessary to confirm these findings.
