Results the safe angle range for needling yamen (gv 15) were: 16.27±7.68～29.46±7.23 degrees for males and 18.46±4.81—33.61±7.83 degrees for females; the danger angle of upward oblique insertion was negatively correlated with the extension of bowing and raising the head, that is, the larger the angle of backward raising the head, the smaller the range of danger angle of needling into the great occipited foramen.

结果：得出哑门穴安全针刺角度，男性为16.27±7.68～29.46±7.32度，女性18.46±4.81～33.61±7.83度。且向上斜刺的危险角度范围与头颅俯仰程度呈负相关，即头颅后仰角度越大，刺入枕骨大孔的危险角度范围越小。

The product is in the pore structure on the graft copolymer of styrene divinyl benzene [-N amines (CH 3) 2 The ion exchange resin], the less alkaline, in the acidic, neutral and effective exchange of inorganic acid medium. and the larger size can be adsorbed molecules in aqueous solution and the use of anion.

本产品是在大孔结构的苯乙烯二乙烯苯共聚体上接枝叔胺基[-N（CH3）2]的离子交换树脂，其碱性较弱，能在酸性、近中性介质中有效地交换无机酸，并能吸附分子尺寸较大的阴离子以及在非水溶液中使用。

Methods:(1) Silica column chromatography and LH-20 were used in phytochemistry study.(2) Based on the extraction ratio of arctiin, the best extraction procedure was acheived under the direction of L9(34) orthogonal experimental design. From 10 types of resins, the one with the maximal binding ability for Arctii was selected and silica-column choramatograpy was used in its seperation and purification procedure.(3) The animal diabetic experimental model in Wistar rats was established with streptozotocin and many biochemical factors were used to indicate the pharmacological effects of arctiin, including glycosylated hemoglobin, serum creatinine, seralbumin, monoxide nitrogen, glycerin trilaurate, cholesterol, HDL-ch, LDL-ch, Blood urea nitrogen, creatinine, SOD, ET, MDA, total Urine protein and albuminuria.
