The results of experiment show the optimal extraction condition of Gardenia Yellow: refluxing and extracting three times with 50 percent ethanol in 55℃, water-bath and extracting 4 to 5 hours, Gardenia Yellow extract solution is separated by X-5 absorption resin, and then with 30 percent ethanol, getting Geniposide white crystal, the determining purity by HPLC come to 99.1% and can be used as standard, the part doffing by 70% ethanol can be concentrated to get more pure Gardenia Yellow pigment.

实验证明了栀子黄的最佳提取条件：50%的乙醇回流提取3次，55℃水浴加热，提取时间为4-5个小时。栀子黄提取液经X-5大孔吸附树脂分离，用30%乙醇溶液洗脱，纯化得到栀子苷白色晶体，HPLC检测纯度达99.1%，可做标准品使用。70%乙醇洗脱部分浓缩可得栀子黄产品，精制后产品纯度有显著提高。

The making process includes: setting insulating solid film on one horizontal rotating carrier with particle detecting unit and etching with single particle beam in the incident angle of 9.6-90 deg to penetrate the film, shifting the film relatively to the single particle beam and etching for the next time, and so on until the film is rotated by one turn to obtain truncated cone shaped, double turned truncated cone shaped or cylindrical single nanometer hole.

本发明将固体绝缘薄膜置于带有粒子检测装置的一个可水平旋转的载体上，用单粒子束刻蚀该薄膜，单粒子束入射角大于等于9.6°、小于等于90°，并且单粒子束在该薄膜底部、顶部、或二者之间与薄膜旋转轴交叉，待单粒子束完全穿透该薄膜后，固体绝缘薄膜底部的粒子监测器反馈使该薄膜被穿透处与单粒子束相对移动1荆再刻蚀，如此反复，直至固体绝缘薄膜旋转一周，获得圆台形、双倒圆台形或圆筒形的单纳米孔。

Three parts of eluates, 20%, 50% and 95% ethanol eluate were obtained, separately.

结果甲醇直接提取所得到的共有峰为7个，而经大孔树脂柱层析后50%乙醇洗脱物得到共有峰11个。

The hospital can make very difficult operations such as resection of hepatic lobes, ablation of encephaloma, radiofrequency catheter ablation of preexcitation syndrome with atrical-ventricular tachycardia, installation and monitoring of permanent artificial pacemaker, artificial joint replacement of femoral necrosis, total hip revision arthro-replacement, posterior vitrectomy combined with autologous serum blocking macular hole, mouth floor jow and neck combined radical operation of oral carcinoma etc..

医院能开展肝叶切除术、脑瘤摘除术、射频消融治疗综合症合并室上性心动过速、永久性人工心脏起搏器安装与监测、股骨坏死人工关节置换术，全髋翻修置换术、后段玻璃体切除术、气液交换术、自身血清封闭黄斑裂孔，口腔癌口底颌劲联系根治术等高难度手术。

The anatomic femoral attachment site of the FCL, slightly proximal and posterior to the lateral epicondyle, 20 was isolated, and an eyelet pin was drilled proximomedially across the distal femur through the center of the FCL femoral attachment site. A 7-mm reamer was then reamed to a depth of 25 mm over the eyelet pin, and a 7-mm bioabsorbable screw tap was used to tap the tunnel.

FCL在股骨外上髁后侧稍靠近端的解剖学附着点[20]离断，通过股骨FCL附着点的中心穿过股骨远端在靠内侧用小针钻孔，然后用7mm扩孔钻顺小钉扩至深度为25mm，使用7mm可吸收螺钉攻丝形成隧道。
