“…Ultrasonic solid to liquid extraction method and solvent extraction separation were adopted for producing proanthocyanidins extract from Sanguisorba. The extraction separation method can specifically be referred in the literatures [7] . b.Test and Determination of Ability to Resist Liposome Peroxidation [ 8] Lecithin liposome oxidation method induced by Fe 2 + was used to test and determine sample's ability to resist liposome peroxidation.…”

We introduced the oxidation method of Lecithin liposome which induced by Fe2+ and fluorescence chemiluminescence method. The method used to determine the ability of the proanthocyanidin extracted from Sanguisorba of inhibit liposome peroxidation, scavenge superoxide anion(O2－.) and hydroxyl free radical(·OH). We carried out a comparative analysis with rutin, extract of Grape Seed and vitamin E (VE) in antioxidant ability. As revealed in the results, compared the extract of Grape Seeds and VE, the inhibition ratio of proanthocyanidin extracted from Sanguisorba to inhibit liposome peroxidation is 1.62 and 7 times, scavenge superoxide anion (02－.) is 1.6 and 10.15 times and scavenge hydroxyl free radical（.OH）is 1.9 and 29.5 times, respectively. The results demonstrate that proanthocyanidin extracted from Sanguisorba show better antioxidant ability, which further revealed that resource of sanguisorba is more worth exploiting and applying.

“…However, with the rapid development of urbanization in recent years, those of affairs of harm to residents and visitors have already happened in many cities and urban regions. From 2000 to 2005, the reports about the attacks to inhabitants are over one thousand in different regions spreading about 17 provinces, municipalities and autonomous regions such as Shanghai, Chongqing, Shandong, Jiangsu, Shaanxi, Zhejiang, Anhui, Hunan, Hubei, Guangdong, Guangxi, Fujian, Hainan, Sichuan, Yunnan, Guizhou and so on, and there are about a total of 60 people stinged to death (no news reports are not included) [3].…”

The traditional removal method of a vespiary is labor-costing with characteristics of low efficiency and safety. According to the work high above the ground with hidden risk of the vespiary removal, a mechanical vespiary exsector was designed. The exsector is driven by a high speed motor, and the vespiary is removed by a cutting wire with high revolution speed. The cutting part can rotate 90 through drawing a pulling rope. A 2-layer sealing mechanism is operated through another pulling rope. The vespiary exsector has overall characteristics of small scale, light weight and good dexterity. Orthogonal experiment results show that factors of cutting speed and feed speed significantly contribute the width of cutting slot at the significance levels of 0.01 and 0.05 respectively, and the optimum cutting parameters are: cutting speed 10000rpm, feed speed 0.04m/s and diameter of the cutting wire 2mm.
