Contrast-enhanced Ultrasound(1) Renal occupied lesions: the contrast-enhanced imaging feature of renal cell carcinomas are multiformity. It was different in time of start-enhancing and start- expurgation and intensio.3 cases revealed wash-in contemporarily and 6 cases revealed wash- in quickly in time of start-enh ancing.In time of start-expurgating, 3 cases showed wash-out quickly, 3cases revealed wash-out contemporarily,3 cases showed wash-out slowly,6 cases revealed a higher contrast enhancement and 3 cases revealed a even contrast enhancement in enhancing intension; 4 cases with renal cyst s,outline had more clear and inside had no contrast media washing in and enhancing;3cases with renal angiomyolipomas washed in slowly,washed out slowly and equal or low enhanced ; 2cases with renal columnar hypertrophy were no outline appearance and the same enhancement and ech o as the nomal rena tissue.

超声造影诊断结果：(1)肾占位性病变：9例肾透明细胞癌，其超声造影表现多种多样，造影后肾脏恶性病灶造影开始增强的时间、开始廓清的时间及增强强度不等，在开始增强的时间方面，与正常肾皮质同时灌注增强的有3例，表现为快进的有6例，在开始廓清的时间方面，快退3例，同退3例，慢退3例，在增强的强度方面，6例病灶表现为高增强，3例为等增强表现；4例肾囊性病灶，超声造影轮廓较二维超声清晰，但内部始终未见增强；3例肾血管平滑肌脂肪瘤表现为慢进慢退，回声呈等、低增强表现；2例肾柱肥大超声造影无明显包块轮廓出现，造影增强的动态变化时间、强度与正常肾组织一致。

A preferred form of the invention is a process comprising adding to a quantity of sodium which is covered with a hydrocarbon solvent boiling above 100°C., at least a chemically equivalent proportion of methyl, ethyl or a propyl alcohol, subsequently adding an approximately equivalent proportion of a dialkyl carbonate and of an alkyl phenylacetate, the alkyl groups in these two last-mentioned compounds being preferably the same as the alkyl radical of the above-mentioned lower aliphatic alcohol, heating the mixture to induce reaction and continually distilling out the alcohol formed from the reaction zone.

本发明的理想形式包括下面的工艺过程：把至少处于化学平衡的甲醇，乙醇或丙醇添加到覆盖着沸点超过一百摄氏度的碳氢化合物溶剂中，接着加入大约相同当量的二烷基碳酸酯和烷基乙酸苯酯，在刚才提到的化合物中，其烷基集团最好是和刚才提到的低级别脂肪族醇相同，然后加热反应混合物从而引导反应的进行，在反应区域通过连续蒸馏移除形成的醇类。

Process for the manufacture of a dialkylphenylethylmalonatewhich comprises adding to a quantity of sodium which is covered with a hydrocarbon solvent boiling above 100°C, at least a chemically equivalent proportion of methyl, ethyl or a propyl alcohol, subsequently adding an approximately equivalent proportion of a dialkylcarbonate and of an alkyl phenylacetate, the alkyl groups in these two last-mentioned compounds being preferably the same as the alkyl radical of the above –mentioned lower aliphatic alcohol, heating the mixture to induce reaction and continually distilling out the alcohol formed from the reaction zone and finally causing the sodio diethyl phenylmalonate so formed to interact with an ethylating agent.

生产二烷基苯基丙二酸酯的工艺过程：这包括这包括把至少处于化学平衡的甲醇，乙醇或丙醇添加到覆盖着沸点超过一百摄氏度的碳氢化合物溶剂中，接着加入大约相同当量的二烷基碳酸酯和烷基乙酸苯酯，在刚才提到的化合物中，其烷基集团最好是和刚才提到的低级别脂肪族醇相同，然后加热反应混合物从而引导反应的进行，在反应区域通过连续蒸馏移除形成的醇类。最后使所形成的钠代二乙基苯基丙二酸酯和乙基化试剂反应。

Cholesterol gallstones formed in C57L mice and fatty livers developed in AKR mice. Conclusions Biliary cholesterol hypersecretion is the key pathophysiological defect of gallstone formation, lith genes have effects on biliary cholesterol hypersecretion and susceptibility to cholesterol gallstone formation in C57L mice. Lithogenic bile is formed at the canalicular membrane and precedes the development of cholesterol gallstones. It is most likely that cholesterol and bile acid hyposecretion make the AKR strain susceptible to the development of fatty livers and resistant to gallstone formation.

结论胆道胆固醇的高分泌是胆囊胆固醇结石形成的主要病理生理基础，结石基因决定了C57L鼠肝内胆汁中胆固醇的高分泌和胆囊胆固醇结石的易患性，成石胆汁形成在肝内胆管，先于胆囊结石的形成；肝内胆汁中胆固醇和胆酸的低分泌可能与AKR鼠脂肪肝的发生和胆囊结石的免患性有关。

When induced to differentiate in the presence of Oleaceae oil (35-130 mg/ml), 3T3-L1 preadipocytes dose- dependently reduced their ability to accumulate cellular triglycerides. Cytoplasmic triglyceride droplets could also be visualized by microscopic observation. Cells treated with 130 mg/ml Oleaceae oil retained their morphology as spindly fibroblasts, while normal adipocytes take on a rounded shape filled with triglyceride droplets.

在开始刺激细胞分化的同时，以 35 mg/ml 到 130 mg/ml 不同的木樨科精油浓度处理细胞，为期八天，将分化到第八天的细胞收下来测三酸甘油酯的浓度当作分化程度的指标，结果发现随著木樨科精油浓度的增加，细胞所累积的三酸甘油酯浓度就越低，用显微镜观察即可发现细胞中脂肪油滴所占的比例明显降低。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
