In this paper, through a series of experiments, two series of quaternary-ammounium Gemini surfactants were synthesized, namely the pair alkylene double quaternary ammonium salt surfactant m-s-m·2Br and the pair the alkylene double quaternary ammonium salt surfactant -s-·2Br. We has carried on the attribute with the infrared spectrum to its structure, and to affected the factor which the synthesis pair the alkylene double quaternary ammonium salt surfactant responded to carry on the discussion. We has discovered the synthesis pair the ethylene double quaternary ammonium salt surfactant m-2-m·2Br optimum condition: The bromo alkane and a tetramethyl ethylene diamine mole of ratio is 3.0: 1.0, makes the solvent by the ethyl alcohol, 80℃ under responds for 48 hours in the backflow temperature; Synthesis pair alkylene double quaternary ammonium salt surfactant 12-S-12 ·2Br optimum condition: 12 tertiary amine and 1, 3- propylene dibromide (1, 4- two bromines butane) a mole of ratio is 2.2: 1.0, makes the solvent by the ethyl alcohol, responds for 48 hours in the constant temperature 80 ℃ under backflow.

In the second part of this research, the effect of the addition of ethanol on the micellization of C14TAB was studied also by ITC at temperatures of 15-40℃. The results show that with increasing ethanol concentration the cmc values first reach a minimum at an intermediate ethanol mole fraction xmin and then increase with increasing ethanol mole fraction.

Results The expression of CD146 was remarkably elevated in malignantly transformed mole than that in normal villi and non- malignant transforming mole （P〈0.01 respectively）,the sensitivity and specificity of CD146 in predicting malignant transformation of complete hydatidiform mole was 71.05% and 78.57% respectively.
