Tending of wild Heterosmilax yunnanensis / 中国中药杂志

To minimize the predatory harvest of Heterosmilax yunnanensis and maintain the sustainable utilization of its resources, a study on the tending technology of wild H. yunnanensis was carried out. The results showed that the tuber tending model had a higher seed emergence rate, shorter growth period and easier control of male and female ratios than other tending models; by removing shrubs, topping, bending pruning, controlling insects and pests and other effective technical measures, the growth period of H. yunnanensis was shortened; the average annual net income of the tending area was 1 086 yuan/mu (1 mu≈666.67 m²), which was 86.9% higher than before. This study was conducive to increasing the yield and quality of H. yunnanensis in Karst landform area, and instructive for the tending of other wild traditional Chinese medicinal herbs in this area.

Effect of Chinese Herbs Used in Treating Multiple Sclerosis on T Subsets Using Association Rules / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To analyze the effect of Chinese herbs used by Prof. LI Tao on peripheral blood T subsets in treating multiple sclerosis (MS) by using association rules and statistical methods, thereby providing evidence for optimizing prescriptions.</p><p><b>METHODS</b>Data of MS inpatients and outpatients recorded by data collecting system, Xiyuan Hospital, China Academy of Chinese Medical Sciences were resorted. The relationship between Chinese herbs and T cell subsets were analyzed using SPSS17.0 and Aprior module in SPSS Clementine 12.0.</p><p><b>RESULTS</b>Radix bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, and Radix Glycyrrhizae were most commonly used herbal combinations.Radix Aconiti lateralis preparata and Rhizoma Smilacis glabrae were often added. Radix Aconiti lateralis preparata was associated with decreased Th1 cells (confidence level 83.78%, supportive level 36.26%). Decreased Th1 cell was associated with Radix Aconiti lateralis preparata (confidence level 71.26%, supportive level 36.26%).Radix Aconiti lateralis preparata was obviously associated with decreased Th1 cells. Radix Bupleuri, Radix Paeoniae alba, bitter orange, Atractylodes , Radix glycyrrhizae, and Radix Aconiti lateralis preparata could reduce peripheral blood Th1 subsets of MS patients and elevate Th2 subsets (all P < 0.01).</p><p><b>CONCLUSIONS</b>The herbal combination of Radix Bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, Radix Glycyrrhizae, Rhizoma Smilacis glabrae, and Radix Aconiti lateralis preparata could lower peripheral blood Th1 cells and elevate Th2 cells, and prevent the relapse of MS possibly by reducing Th1 cells and elevating Th2 cells. Especially Radix Aconiti lateralis preparata played important roles in aforesaid changes of Th1 and Th2.</p>

Smilax campestris Griseb. ­Smilacaceae­: variaciones en la producción polifenoles en hojas sanas y atacadas por la oruga de la mariposa Agraulis vanillae L. ­Heliconidae­ / Smilax campestris Griseb. -Smilacaceae-: variations in polyphenol production in healthy leaves and attacked by the caterpillar of the butterfly Agraulis vanillae L. -Heliconidae-

Smilax campestris Griseb. ­Smilacaceae­ es una especie empleada en la medicina popular. Sus hojas se utilizan en infusiones para la elaboración de bebidas tónicas, amargas y digestivas. El objetivo de este trabajo es la comparación de las variaciones cuali-cuantitativas en el contenido de los polifenoles de las hojas de S. campestris sanas con las atacadas por la oruga de la mariposa Agraulis vanillae L. ­Heliconidae­. En las hojas atacadas se determinaron mayores concentraciones de los derivados de quercetina, canferol e isoramnetina con respecto a las hojas sanas. Además, se producen nuevas glicosidaciones que no están presentes en las hojas sanas. La concentración de fenoles totales es de 3,46 ± 0,62 mg de ácido tánico/gramo de material fresco en hojas sanas y de 12,96 ± 2,06 mg de ácido tánico/gramo de material fresco en hojas atacadas. Estos resultados concuerdan con estudios realizados en otras especies vegetales, donde la acción de los herbívoros genera aumento en los niveles de polifenoles. Por lo tanto, se deduce que las hojas de S. campestris modifican el metabolismo de los polifenoles como mecanismo de defensa contra predadores.
