肾循环阻断情况下经导管动脉无水乙醇栓塞治疗大肾细胞癌的初步研究

评价经导管动脉栓塞（TAE）与经球囊封闭肾引流静脉抽吸术（TAE—ABOD）共同治疗大肾细胞癌的安全性。对25例肾细胞癌病人共行27次TAE—ABOD手术。TAE—ABOD手术包括球囊封闭肾引流静脉和经球囊导管抽吸血液的同时灌注无水乙醇2个步骤，以减少无水乙醇进入体循环的漏出量。最初的研究目标是建立一种高剂量无水乙醇注射治疗的方法．其次是评估全部病人的总体生存率。

Confirmation/Observation of Hindered E2 Strengths in ^(16,18)C

The lifetime of the first excited 2+ state in 18C was measured using an upgraded recoil shadow method to determine the electric quadrupole transition. The measured mean lifetime is 18.9±0.9(stat)±4.4(syst)ps,which corresponds to a B(E2; 2+1→0+gs) value of (4.3± 0.2±1.0) e2fm4,or about 1.5 Weisskopf units. The mean lifetime of the first 2+ state in 16C was remeasured to be about 18 ps,about four times shorter than the value reported previously. This discrepancy was explained by incorporating the γ-ray angular distribution measured in this work into the previous measurement. The observed transition strengths in 16,18C are hindered compared to the empirical transition strengths,indicating that the anomalous hindrance observed in 16C persists in 18C.
