Purpose: In order to observe the therapeutic effect of electric acupuncture plus Tuina therapy for cervicogenic headache. Methods: 200 cases of the patients with cervicogenic headache were allocated randomly into electric acupuncture plus Tuina group (Group A, n=100), electric acupuncture group (Group B, n = 50) and Tuina group (Group C, n = 50) and treated respectively by electric acupuncture on cervical Jiaji (Ex-B 2)points, Fengchi (GB 20),Ashi points, Shuaigu (GB 8), Yifeng (TE 17), Touwei (ST 8) and Waiguan (TE 5) on the sick side and Tuina therapy. Results: The total effective rate was 100% in Group A, 90.0% in Group B and 88.0% in Group C, with a significant difference (P＜ 0.05). Conclusion: Electric acupuncture plus Tuina therapy is an effective method for cervicogenic headache.

OBJECTIVETo analyze the dynamic change of chemical constituents in Changium smyrnioides at different ages and give a reference for standard cultivation.

METHODThe contents of polysaccharides, mannitol and choline in the roots were determined by colorimetry. HPLC was used to analyze water-soluble components in the roots. GC-MS was used to analyze volatile oil components in the leaves. Similarity coefficient of water-soluble components was calculated by included angle cosine method.

RESULTThere was significant difference in content of the analyzed chemical constituents except polysaccharide. Contents of mannitol, physiological ash and polysaccharide in the adult plant were higher than those in the young plant. On the contrast, content of water-soluble components and choline in the young plant was higher than that in the adult plant. With the increase of the growth years, water-soluble components in the roots and volatile oil components in the leaves were gradually concentrated.

CONCLUSIONThe growth time significantly affects the chemical constituents in Ch. smyrnioides, the reasonable harvest time is from the second to the forth year after transplanting.

OBJECTIVETo analyze water-soluble components in the roots of Ch. smyrnioides among different populations that distributed in the main areas and give a reference for germplasm evaluation and quality control.

METHODWater-soluble components were extracted with the cold-soaking method and analyzed by HPLC, similarity coefficient was calculated by included angle cosine method according to relative content of major water-soluble components, and systematic relationships were constructed based on UPGMA method.

RESULTThere was significant difference in water-soluble components in root among population. Jiuhuashan population had the highest content of water-soluble extract. The content of water-soluble extract was below the pharmacopoeia standard in the root of Dalongshan population and Fushan population. There was significant difference in the HPLC chromatogram of water-soluble components in the root of Ch. smyrnioides from different populations, and the number of common peak was small. Similarity coefficient significantly ranged from 0.0306 to 0.9995 among 10 populations of Ch. smymrnioides. Water-soluble components in the root of Zijinshan population was the most unique, similarity coefficients were relatively small among Zijinshan population and the other seven populations except Hongshan population, and similarity coefficient was in a higher level of 0.9697 between Zijinshan population and Hongshan population. Water-soluble components were extremely similar in four populations that were Laoshan, Maoshan, Qinglongshan and Langyashan, and similarity coefficients among them were in a high level exceeded 0.99. 10 populations were divided into 3 groups according to clustering results.

CONCLUSIONWater-soluble components show a high diversity in the roots of Ch. smyrnioides among different populations, and can be clearly divided into 3 types.

OBJECTIVETo analyze the distribution of chemical constituents in different parts of Changium smyrnioides.

METHODThe content of polysaccharides, mannitol and choline was determined by colorimetry and the water-soluble components was determined by HPLC. similarity coefficient of water-soluble components was calculated by the included angle cosine method.

RESULTThe Contents of chemical constituents were significantly different between the leaves and the roots. The contents of choline and polysaccharides in the roots was higher than those in the leaves, but the contents of water-soluble extract and physiological ash in the leaves was higher than those in the roots. Contents of chemical constituents were also significantly different at different segments in the root, which decreased from the upper to the lower parts, increased from the outside to the inside parts except physiological ash, and the difference in horizontal segments was higher than that in vertical segments. Total peak area of water-soluble components in the leaves was 2.81 times higher than that in the roots, and gradually increased from the outside to the inside parts.

CONCLUSIONTotal content of chemical constituents in the leaves was significantly higher than that in the roots. The quality of medicinal used parts decreased gradually from the inside to the outside parts and from the upper to the lower parts in the root of Ch. smyrnioides.
