The optimum conditions are: molar ratio of glycol to cyclohexanone is 1.6:1, the quantity of catalyst is equal to 0.25% of feed stocks, and the reaction time is 40 mm. H3PW12O40/MCM-48 is an excellent catalyst for synthesizing cyclohexanone ethylene ketal and its yield can reach over 80.63%.

实验表明：H3PW12O40/MCM-48是合成环己酮乙二醇缩酮的良好催化剂，在n：n＝1：1.6，催化剂用量为反应物料总质量的0.25%，环己烷为带水剂，反应时间40min的优化条件下，环己酮乙二醇缩酮的收率可达80.63%。

Base on the stress analysis, the model with unit of porcelain to metal at the labiocervical margin is better than the models with porcelain or metal only at labiocervical margin for upper central incisor restoration.

从受力分析的角度而言，金属颈环型设计适应于前磨牙和后牙的修复：瓷颈环型设计适应于前牙修复，而金-瓷混合颈环型设计则适应于任何形式的修复体。

The first synthetic route uses 1,2,4-trimethoxybenzene and chloroacetonitrile in forming 2,4,5-trimethoxy-a-chlor-acetophenone under the anhydrous condition, then the intermediate condensates with papaverine forming the core pyrro[2,l-a]isoquinoline, followed by formation and lactonization to form the lactone ring. The second synthetic route uses prepared aldehyde with prepared ethyl nitroacetate by Knoevenagel condensation to obtain 2-Nitro-3-(2,4,5-tris-methoxy-phenyl)-acrylic acid ethyl ester and 2-Nitro-3-(2,4,5-tris-benzyloxy -phenyl)-acrylic acid ethyl ester etal intermediates. The lamellarin skeleton could arise from condensation of the papaverine and these intermediates by Michael reaction, the ester group is provided for subsequent lactonization. The third synthetic route uses coumarin or indan-l,3-dione derivatives and papaverine to form lamellarin under basic conditions.

第一条路线首先从1，2，4-三甲氧基苯出发与卤乙腈作用合成卤代芳酮中间体，然后与罂粟碱反应合成开链片螺素，最后经乙酰化、去保护、成内酯环得到片螺素；第二条路线由制备的芳醛和制备的硝基乙酸乙酯经缩合得到2-硝基-3-芳基丙烯酸乙酯，然后由该中间体与罂粟碱反应，在完成关环的同时也引入酯基，最后去保护、成内酯环得到片螺素；第三条路线是由香豆素或茚二酮出发，经溴代后的中间体与罂粟碱反应，得到片螺素的基本框架。

Results: The extract of propolis had certain antineoplasm effect and the inhibition rate of propolis extract on tumor is 27.74％ and when combined with cyclophosphamide, the inhibition rate reached to 50.32％, even antagonized leucocytopenia caused by cyclophosphamide.

结果：蜂胶提取物的抑瘤率为27.74％，与环磷酰胺合用的抑瘤率为50.32％，比单用蜂胶提取物及环磷酰胺分别提高22.58％和9.03％(P＜0.05)，并能减轻环磷酰胺所致的骨髓造血功能抑制，使血液白细胞维持在正常水平(P＜0.01)。
