Research status on efficacy enhancement and toxicity reduction of Chinese medicine in treatment of malignant tumors: a review of projects supported by National Natural Science Foundation of China / 中国中药杂志

Through a retrospective analysis of the projects supported by the National Natural Science Foundation of China in the past ten years in the field of Chinese medicine for the treatment of malignant tumors, this article systematically summarized the main research contents and hotspots of Chinese medicine in efficacy enhancement and toxicity reduction. The efficacy enhancement of Chinese medicine mainly included the mitigation of molecule-targeted drug resistance, multidrug resistance, and chemotherapy resistance, synergistic efficacy enhancement, and radiotherapy sensitization. The toxicity reduction is mainly reflected in the alleviation of the side effects of radiotherapy and chemotherapy. In addition, Chinese medicine has advantages in reducing serious adverse reactions of malignant tumors, providing more options for the adjuvant treatment of tumors.

This paper introduces the application and financing of programs of efficacy material base of traditional Chinese medicine funded by the National Natural Science Foundation of China(NSFC), the Youth Science Fund and the Regional Science Fund from 2016 to 2019, and conducts analysis and summary in terms of research objects and analysis methods, with the aim to provide reference for applicants for programs of efficacy material base of traditional Chinese medicine.

Analysis on projects of ethnomedicine and ethnopharmacology funded by National Natural Science Foundation of China from 1986-2018 / 中国中药杂志

Through summarizing the applications and funding for research related to ethnomedicine and ethnopharmacology in the department of Health Sciences of the National Natural Science Foundation of China( NSFC) from 1986 to 2018,and analyzing the categories,numbers,funds and research contents of all funded projects including Mongolian,Uygur,Tibetan,Zhuang,Miao,the study is aimed to provide certain reference for the declaration of ethnic medicine project. The results showed that the national medicine project application numbers and the amount of funding growth after 2011 have increased significantly,but the overall level of research remained to be further promoted,and the lack of suitable for the study of ethnic medicine features and ways,has yet to mainland medical universities and research institutions to give more attention and jointly promote the development of basic research in the field of ethnic medicine.

Herbs protect against osteoporosis through anti-inflammation action / 中国组织工程研究

BACKGROUND: The occurrence and development of osteoporosis are shown to be directly related to the inflammatory response induced by immune dysfunction. OBJECTIVE: To summarize the mechanisms of osteoclast differentiation and formation at cellular and molecular levels, as well as the underlying mechanisms of several kinds of medical herbs against osteoporosis, thus paving ways for finding more effective and safe herbs for anti-osteoporosis.METHODS: PubMed database was retrieved using the English keywords of (osteoporosis OR bone loss) AND lipopolysaccharide AND bone resorption", and WanFang database was searched with the Chinese keywords of "osteoarthritis, receptor activator of nuclear factor-κB ligand, lipopolysaccharide,Dendrobium moniliforme,Portulaca oleracea,Ampelopsis sinica,Schizonepeta".The literatures addressing osteoporosis, inflammation and herbal medicine were screened, and those using lipopolysaccharide-induced mouse models were included. Finally, four eligible literatures were enrolled for review. RESULTS AND CONCLUSION:In vivo experiments,CT images and pathological sections of the cancellous bone in the mouse distal femur show that Dendrobium moniliforme,Purslane oleracea,Ampelopsis sinica,and Schizonepeta exert inhibitory effects on lipopolysaccharide-induced osteoporosis.In vitro experiments reveal that these four kinds of herbs fight against osteoporosis by inhibiting osteoclast differentiation and further reducing bone resorption.

Clinical outcomes of intravascular ultrasound in guiding the treatment of non-left main intermediate coronary lesions for patients with acute coronary syndrome / 南方医科大学学报

<p><b>OBJECTIVE</b>To evaluate the long-term clinical outcomes of intravascular ultrasound(IVUS) in guiding the treatment of non-left main intermediate coronary lesions for patients of acute coronary syndrome (ACS).</p><p><b>METHODS</b>A total of 25 patients with intermediate coronary lesions(stenosis of 40%-70%) confirmed by coronary angiography were performed with IVUS. When MLA≥4 mm, we deferred the PCI treatment and performed optimal medical treatment (OMT). The patient were followed up for 12 month. The primary outcome was target vessel revascularization (TVR) and secondary outcome was major adverse cardiac events (MACEs).</p><p><b>RESULTS</b>A total of 25 lesions of 25 patients were examined by IVUS. 19(76%) lesions were attenuated plaque, 4(16%)were echo-lucent plaque, 2(8%) were calcified plaque. Most of the plaque (18/25, 72%) were eccentric. Positive remodeling was found in 20(80%) lesions and negative remodeling in 5(20%) lesions with meanremodeling index of 1.17=0.15. Thrombus was found in 1 case, accounting for 4%. The diameter stenosis, area stenosis, minimal lumen area and the reference diameter mea-sured by IVUS were larger than those measured by quantitative coronary angiography (all P<0.05). One patient with non-ST segment elevated myocardiac infarction was performed revascularization because MI attacked again, and 2 patients with Unstable angina were treated with OMT but they were still rehospitalization because of angina occurred repeatedly. The incidence of TVR was 4.00%, so as 16.00% of MACE.</p><p><b>CONCLUSION</b>IVUS can be used to guide the treatment of non-left main intermediate coronary lesions for patients of acute coronary syndrome.</p>

Identification of polygala oligosaccharide esters and their metabolites in rat plasma after oral administration of ethanol extract of Kai Xin San by UHPLC-MS / 药学学报

Using a UHPLC-TOF/MS method combined with software of Masslynx V4.1 and database in the literatures, a total of 20 polygala oligosaccharide esters (POEs) were identified in 60% ethanol extract of Kai Xin San (KXS-60%E). Furthermore, 14 POEs as well as 4 POE-metabolites were identified in rat plasma. The results revealed that POEs and POE-metabolites which were identified in rat plasma, were key components in KXS-60%E and the potential bioactive compounds for KXS action in the treatment of AD.
