Objective: To establish an optimal extraction process of the total glycoalkaloids in Solanum tuberosum L. and then study the anti-inflammatory activity. Methods:The extraction process of the total glycoalkaloids was optimized by orthogonal design. Compared with that of the total glycoalkaloids in Rhizoma Dioscoreae Melanophymatis and fresh potato pieces, the anti-inflammatory ac-tivity of the total glycoalkaloids in Solanum tuberosum L. was evaluated by mouse ear swelling model induced by xylene, rat paw swell-ing model induced by carrageenan, granuloma model caused by cotton and blood capillary permeability experiments. Results:The opti-mal extraction conditions were as follows:the extraction temperature was 65℃, 10-fold amount of methanol was used for twice extrac-tion with 45 min per time. The total glycoalkaloids from the optimal extraction had obvious anti-inflammatory activity,and the effect was related to the content ofα-chaconine. Conclusion:The results show that the order of different factors affecting the extraction rate is ex-traction temperature> extraction time, and the total glycoalkaloids in Solanum tuberosum L. has good anti-inflammatory effects in mice and rats.

plant height.Multiple regression analysis showed that branch height from base(X_2),number of primary branches(X_4),number of effective cones per plant(X_6),number of ineffective cones per plant(X_7),number of grains per cone(X_9),and diameter of primary head(X_(10)) were the main factors affecting flower yield(Y) per plant.Multiple regression equation of flower yield per plant and six characters was Y=-3.037 0+(0.002 7) X_2+0.045 9 X_4+0.074 5 X_6+0.043 2 X_7+0.023 0 X_9+1.148 2 X_(10)(F=21.84~()).The direct effect of number of effective cones per plant was the strongest,followed by diameter of primary head.There were significant differences within the flower yield per plant and the safflor yellow A content of different species.The correlation between the safflor yellow A content and the flower yield per plant was insignificant.Conclusion High-yield and high-quality are compatible in breeding of safflower which is used as herbal medicine.Number of effective cones per plant and diameter of primary head are focused on the high yield breeding and cultivation of safflower species.The plant type of higher flower yield safflower species should have more effective cone numbers,more number of cones,number of branches,number of primary branches,bigger diameter of primary head,moderate plant height,branch height from base,and ineffective cones per plant.Of all accessions,PI 239226,PI 253540,PI 367833,and Jianyang Honghua are outstanding and optimal for cultivating in Sichuan Province.

Objective To observe the effect of Weichangshu Capsule (WCSC) in inhibiting experimental gastric ulcer and the damage of gastric mucosa in SD rats. Methods The experimental gastric ulcer rat models were established by ligation of pylorus, water immersing method and subcutaneous injection of indometacin, and rat models with acute damage of gastric mucosa were induced by hydrochloric acid- ethanol (HAE).Then the effect of WCSC in inhibiting experimental gastric ulcer and the damage of gastric mucosa in SD rats were observed. Results WCSC had obviously inhibitory effects on stress gastric ulcer, indometacin- induced gastric ulcer and HAE- induced acute damage of gastric mucosa. WCSC also inhibited the secretion of gastric juice and increased pepsase activity. Conclusion WCSC has counteraction on experimental gastric ulcer.

“Mechanical memory” approach was commonly used in the knowledge learning of traditional Chinese medicine, which makes students often feel that the knowledge is too abstract, and this method is thus ineffective. “Qihuang the way” using Unity 3D game development platform inte-grates the elements of medical knowledge of the Chinese medical history, and combines TCM theoretical knowledge learning with serious games , which can help invoke students' enthusiasm and improve learning efficiency in an entertaining way.
