Searching bioactive natural compound and establishing quality evaluation standard arefocused on this experiment. Using cold immersing of 70% methanol to extract from flower ofAcanthopanax senticosus and integrating macroporous resin, silica gel column chromatography,sephadex gel to abstract. We obtained five monomer compounds (compoundⅠ-compoundⅤ),quercetin, quercetin rhamnoside, hyperin, syringoside and eleutheroside E. That five compoundswere determined by HPLC in eight parts of Acanthopanax senticosus (flower, root, leaf fruit,shoot, new shoot, phloem of shoot, skin of shoot), which provide science bases for establishingquality evaluation system and settle infarctate foundation.

本文以从刺五加花蕾中寻找具有重要生物活性的天然化合物和建立质量评价标准为主要目的，对其化学成分进行研究，采用70％甲醇冷浸的方法对刺五加花蕾中的成分进行提取，运用大孔树脂吸附色谱法、硅胶柱层析法以及葡聚糖凝胶柱层析相结合的方法进行分离，得到5种单体化合物，分别为槲皮素、槲皮素鼠李糖苷、金丝桃苷、紫丁香苷和刺五加苷E；利用高效液相色谱法对这5种化合物在刺五加花蕾中的含量进行了测定；考察了8个部位(花蕾、根、叶、果、茎干、新枝、茎韧皮部、茎皮)中这5种化合物的含量分布情况，并作一比较，为今后建立刺五加质量评价体系提供了科学依据，奠定了坚实的基础。

Methods Forty-eight patients (50 eyes) with diffuse diabetic macular edema were randomly divided into two groups: twenty-five eyes were treated with an intravitreous injection of triamcinolone acetonide (4 mg/0.1 ml), and another twenty-five were treated with a peribulbar injection of triamcinolone acetonide (40 mg/1 ml).

将48例（50眼）弥漫性黄斑水肿患者随机分为曲安奈德玻璃体腔（0.1 ml，4 mg）注射目的总结曲安奈德(triamcinolone acetonide，TA)联合黄斑部格栅样光凝对糖尿病性黄斑水肿的疗效，评估TA的两种不同给药方式的安全性。

A 8-week growth experiment was conducted to estimate the quantitative requirement of tourmaline for GIFT strain of Nile tilapia [initial body weight(15.90±0.1) g] by feeding five isonitrogenous(33%) and isoenergetic(17.2 MJ/kg) diets containing five levels of tourmaline at 0, 0.5％, 1%, 2% and 3%, respectively.

试验以（15.90±0.1） g的吉富罗非鱼为试验对象，在等氮（33%）等能（17.2 MJ/kg）的基础上，在其日粮中分别添加0、0.5％、1％、2％和3％的固相负离子粉，在循环水养殖系统中进行8周的生长试验。每种饲料设计3个重复，每桶放鱼30尾。

One-year-old seedlings of five native species including Dolichandrone cauda-felina, Syzygium jambos, Melastoma candidum, Pterospermum heterophyllu, and Schefflera octophylla were planted in pot containers and acclimated under partially shaded regime for 4 weeks. And further, seedlings of each species were divided into two groups with equivalent individuals for each group, which were exposed to the clean and the polluted site, respectively. After five months, dimensional growth parameters and dry mass allocation were measured and analysed to study the differences in response of these subtropical woody species to atmospheric pollution.

将乡土木本植物猫尾木Dolichandrone cauda-felina蒲桃Syzygium jambos、野牡丹Melastoma candidum、翻白叶树Pterospermum heterophyllum以及鸭脚木Schefflera ctophylla 1年生袋装苗盆栽，置半庇荫环境下适应4周，之后按株数均等分成两组，分别放置在南海五星污染区和广州华南植物园清洁区进行试验。5个月后进行植物构形生长参数和干物质量的测定，以探讨这5种亚热带树苗对大气污染响应的差异。
