Through this issue, we found that with 2% NaOH-NALC digested within 10 minutes in the rapid decomposition of the viscous sputum, in ensuring the effectiveness of digestion at the same time not too much because of the role of NaOH to kill bacteria (time to 20 minutes), and would not affect the role of magnetic particles; quantitative simulation of self-made through the application of clinical samples, we compared the acid-fast stain and auramine O staining of the detection limit, auramine O fluorescence staining against the backdrop of a clear dark green light acid-fast stain of Mycobacterium tuberculosis than the white background of the red eye-catching TB is more capacity, auramine O staining in the detection limit of 0.05 to 0.001 between Maxwell, higher than the acid-fast stain of Michael's 0.05 units, The former is more sensitive; In addition, the accumulation of magnetic nanoparticles of the samples after the smear, in the microscope show the number of TB was significantly higher than that of the specimens has not been enriched.

通过本次课题，我们发现用2%NaOH-NALC消化液可在10分钟内迅速裂解痰液的粘性介质，在保证消化效果的同时不会由于NaOH过强的作用杀死细菌（时间控制在20分钟内），亦不会影响磁性颗粒的作用；通过应用自制定量模拟临床标本，我们比较了抗酸染色和金胺O荧光染色的检出限，金胺O荧光染色黑暗背景下发出明显绿色亮光的结核杆菌较抗酸染色白色背景中的红色结核杆菌更容醒目，金胺O荧光染色的检出限在0.05~0.001个麦氏单位之间，高于抗酸染色的0.05个麦氏单位，前者敏感度较高；另外，经过磁性纳米颗粒富集作用后的标本涂片，在镜下显示其结核杆菌数量明显高于未经过富集的标本。

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.
