Clinical application and mechanism of traditional Chinese medicine in treatment of lung cancer / 中华医学杂志(英文版)

Lung cancer is a malignant tumor characterized by a rapid proliferation rate, less survivability, high mortality, and metastatic potential. This review focuses on updated research about the clinical application of traditional Chinese medicine (TCM) as an adjuvant therapy to lung cancer treatment and the mechanisms of TCM effect on lung cancer in vitro and in vivo. We summarized the recent 5 years of different research progress on clinical applications and antitumor mechanisms of TCM in the treatment of lung cancer. As a potent adjuvant therapy, TCM could enhance conventional treatments (chemotherapy, radiation therapy, and epidermal growth factor receptors [EGFRs] tyrosine kinase inhibitors [TKIs]) effects as well as provide synergistic effects, enhance chemotherapy drugs chemosensitivity, reverse drug resistance, reduce adverse reactions and toxicity, relieve patients' pain and improve quality of life (QOL). After treating with TCM, lung cancer cells will induce apoptosis and/or autophagy, suppress metastasis, impact immune reaction, and therapeutic effect of EGFR-TKIs. Therefore, TCM is a promisingly potent adjuvant therapy in the treatment of lung cancer and its multiple mechanisms are worthy of an in-depth study.

Progress research on effect and mechanism of Chinese materia medica preventing oxaliplatin-induced neurotoxicity / 中草药

Oxaliplatin is the third generation of platinum antitumor drugs, which has the advantages of good efficacy, broad anticancer spectrum and so on. However, peripheral neurotoxicity is the main dose limiting toxicity, which affects not only its clinical application but also the quality of patients’ life. According to Chinese medicine theory, some progress has been made in the treatment of this disease by using the traditional herb with invigorating qi and activating blood and warming yang for removing obstruction in collaterals. This article summarizes the literatures in domestic and foreign countries from the aspects of Chinese prescription and active ingredients, which provides basis for clinicians to treat the neurotoxicity of oxaliplatin.

Study on lignans from Xanthii Fructus / 中国中药杂志

This project is to investigate lignans from the dried fruits of Xanthium sibiricum (Xanthii Fructus). The chemical constituents were extract by 70% ethanol and isolated by silica gel, ODS, Sephadex LH-20, MCI column chromatography. Based on comparison of their spectral data with those reported in literature, they were elucidated as (-)-pinoresinol (1), balanophonin A (2), diospyrosin (3), dehydrodiconiferyl alcohol (4), 2-(4-hydroxy-3-methoxyphenyl)-3-(2-hydroxy-5-methoxyphenyl)-3-oxo-1-propanol (5), (-)-simulanol (6), (-)-7R,8S-dehydrodiconiferyl alcohol (7), chushizisin E (8), dihydrodehydrodiconiferyl alcohol (9), 7R,8S-dihydrodehydrodiconiferyl alcohol 4-O-β-D-glucopyranoside (10), erythro-1,2-bis(4-hydroxy-3-methoxyphenyl)-1,3-propanediol (11), leptolepisol D (12), 8-O-4' neolignan 4-O-β-glucopyranoside (13), (-)-1-O-β-D-glucopyranosyl-2-{2-methoxy-4-[1-(E)-propen-3-ol]phenoxyl}-propane-3-ol(14), 1-(4-hydroxy-3-methoxy)-phenyl-2-[4-(1,2,3-trihydroxypropyl)-2-methoxy]-phenoxy-1,3-propandiol (15), threo-dihydroxy dehydrodiconiferyl alcohol (16), (-)-(2R)-1-O-β-D-glucopyranosyl-2-{2-methoxy-4-[(E)-formylviny1]phenoxyl} propane-3-ol (17). Compound 2-17 were isolated from the genus Xanthium for the first time. Compound 1 were isolated form Xanthii Fructus for the first time.

Exploring effective components of laxative effect of Anemarrhenae Rhizoma based on Chinese herbal processing theory / 中国中药杂志

Anemarrhena asphodeloides processed by salt and raw product was compared including both chemical composition and laxative function in order to find the possible active substance to cure constipation. Processed and raw Anemarrhenae laxative effect on experimental constipation models was observed as well as chemical composition using UPLC-MS technology and the total sugar content was determined by phenol sulfuric acid method. Processed Anemarrhenae water extract improved excrement more than raw which has significant difference compared with the blank group (P < 0.05). On the other hand, the total ion flow spectrum showed no significant difference in most substance, but the total sugar content was significantly higher than raw product. Anemarrhenae ancient be recognized benefitting for draining body water in traditional Chinese medicine which has been lost in modern books because it is manifested as excellent laxative effect not diuretic effect. Saccharides carbohydrate may have closely relationship with this magically effect.
