ABSTRACT

Dendrobium huoshanense is a precious medicinal plant belonging to Dendrobium of Orchidaceae. It is a special medicinal material and extremely scarce in Huoshan county, Anhui province. At present, D. huoshanense has been greatly protected, which also makes it possible to industrialize relying on tissue culture and artificial cultivation technology. Three main planting methods were utilized for cultivating D. huoshanense including facility cultivation, under forest cultivation and simulative habitat cultivation. Firstly, the three cultivation modes and technical characteristics of D. huoshanense were compared and analyzed, and it was found that the ecological environment of D. huoshanense cultivated in the simulated environment was closer to that of wild D. huoshanense. Secondly, based on comparing the characters and quality of three cultivation modes, the results showed that the shape of D. huoshanense cultivated in simulated environment was more similar to that of "grasshopper thigh" recorded in Bencao Jing Jizhu, and its quality was better than that of facilities and under forest cultivation. The comprehensive benefit comparison of three modes showed that the simulated cultivation had high income, the lowest input-output ratio and significant economic benefit. The quality of cultivated D. huoshanense was further evaluated from four aspects of "excellent environment" "excellent shape" "high quality" "excellent effect", which summarized the comprehensive advantages of simulative habitat cultivation of D. huoshanense as follows: the original habitat and site environment of simulated wild D. huoshanense, the closer shape to the wild, the more content of main medicinal components, and higher economic benefit and better efficacy. The quality of D. huoshanense was improved by the use of simulative habitat cultivation, which has practical significance to guide its large-scale cultivation.

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of extract of Ginkgo biloba (Egb761) on doxorubicin-associated cardiotoxicity in patients with breast cancer (BC).</p><p><b>METHODS</b>Sixty BC patients in stage IV were randomly assigned to two groups, the control group was treated with chemotherapy, using 4 cycles of PA protocol alone and the treated group with the same chemotherapy and Egb761. Changes in electrocardiogram (ECG), myocardial enzyme spectrum (MES) and ultrasono-cardiogram (USCG) before and after treatment were observed.</p><p><b>RESULTS</b>After treatment, the incidence of abnormal ECG was lower in the treated group than in the control group (6.7% vs 30.0%); significant differences were found between the two groups in the parameters of MES (P< 0.05); USCG showed significant difference between the two groups in left ventricular diastolic diameter (LVDd), left ventricular systolic diameter (LVDs), ratio of early and late diastolic transmitral peak flow velocity (E/A) and fractional shortening (FS), while there was no significant difference in ejection fraction (EF).</p><p><b>CONCLUSION</b>Egb761 is an ideal drug for preventing and reducing the acute doxorbincin-induced cardiotoxicity; it could also be helpful for alleviating the chronic cardiotoxicity.</p>
