摘 要：中国的新表现主义绘画有着一个较为曲折的发展过程，本文从它的历史背景着手重点对中国的新表现主义绘画的艺术特征作一些浅析。

We report the case of a 63-year-old female who had chronic hepatitis C and who was diagnosed with hepatocellular carcinoma. Hepatic angiography showed one visible and tortuous falciform artery arising as the terminal branch of the left hepatic artery. Transcatheter arterial chemoembolization was performed via the left hepatic artery.

本文报告一位63岁慢性C型肝炎女性，诊断为罹患左肝内叶肝细胞癌，经肝动脉血管摄影显示出一条弯曲可见的镰状动脉由左肝动脉内侧分枝分出。

Selective right bronchial angiogram revealed tortuous hypervascularity which drained back to the right pulmonary vein.

选择性支气管动脉摄影，发现病变部位有丰富且纡曲血管分枝，并注入右肺静脉，疑为肺部肿瘤，连转送外科开刀，作右肺中叶切除术。

Results Among 6 cases with PCTPV, 4 cases revealed occlusion of the main branch of portal vein at the hepatic hilum, 2 cases revealed occlusion of the common portal vein, and a masslike network of tortuous veins around the hepatic hilum and many small irregular veins radiating from the network to the liver were demonstrated.

结果：6例中4例清楚显示门脉主要分支近肝门处阻塞，2例门静脉主干阻塞，代之以肿块样纡曲血管并在其周围形成向肝性放射状侧支血管影像，以及离肝性侧支循环静脉。6例CT血管成像均能对与分流或断流手术有关的血管解剖提供准确信息。

Results 33 cases of CTPV were all showed collateral veins, which were biliary collateral veins of the portal vein (n=33), gastric collateral veins (n=25), pancreaticoduodenal region collateral veins (n=14), parumbilical collateral veins (n=2). The collateral veins were appeared as soft tissue density on precontrast scan, with generally no enhancement on arterial phase, but on venous phase, they were appeared as multiple punctuate, strip, nodous or thin reticulate enhanced vessels, which were with tortuous, abnormally dilated, and cavernous in shape.

结果 33例全部显示侧支静脉，其中显示33例胆支、25例胃支、14例胰十二指肠后上静脉和2例脐旁静脉，侧支静脉CT平扫表现为软组织密度影，动脉期一般无强化，门静脉期显示多发点状、条状、结节状或细网状的强化血管影，走行扭曲，异常扩张，呈海绵样改变；22例显示门静脉栓子，14例显示肝脏灌注异常，12例显示胆系改变，25例显示脾肿大。

While the tissue spaces surrounding a few blood vessels wasAl and Fg positive,no Al or Fg positive cells were observed.In antemortem injurygroup,diffuse subarachnoid hemorrhage,cerebral edema,swelling or pyknotic neu-rons could be observed.The axons showed irregular swelling and disconnection at1～3h,marked swelling and disconnection at 6h,and retraction ball at 15h whichwas more remarkable at 24h after injury.The space between myelin sheaths andaxons was increased at 3～6h after injury.Tortuous and wavelike myelin sheathswhich adhered on axons incompletely,or even peeled off could be found from 15hto 24h after injury.Perinuclear lysis of Nissl bodies began at 24h after injury.Thenumber of GFAP positive cells in cerebrum and brain-stem increased significantlyfollowed by decrease,and then increased again,but the time courses of the changesin different areas of brain were not same.Al and Fg positive neural cells,mainlysurrounded blood vessels,with diffuse or peripherally distributed positive matter incytoplasm could be observed at 0.5h after injury.The number of Al or Fg positivecells and the intensity of immunoreaction increased with the time of injury.The areaof SYN positivity in medulla oblongata and pons decreased notably 3～6h afterinjury,then return to normal levels and continued to 24h after injury.

生前损伤组，可见广泛蛛网膜下腔出血，脑组织水肿，神经细胞肿胀，晚期神经元固缩；伤后1～3h见部分神经轴突不规则增粗、断裂，伤后6h断端膨大，伤后15h可见收缩球，至伤后24h更为明显；伤后3～6h可见部分神经髓鞘与轴突之间的间隙增宽，伤后15h髓鞘明显曲折，不完全附着在轴突两侧，甚至剥脱，持续到伤后24h；核周尼氏体减少在伤后24h才开始出现；同一部位的GFAP阳性细胞数目随损伤时间发生改变，先增多（最早在伤后0.5h），达到高峰后减少，其后又有增多趋势，但不同部位的GFAP阳性细胞数目增减的时间过程不尽相同，同时，大脑中的GFAP阳性细胞数目也有改变；伤后0.5h，可在脑干组织中见到Al和Fg阳性神经细胞，主要位于血管周围，阳性物在胞浆中呈弥散性分布，但部分细胞的阳性物仅分布于靠近胞膜的胞浆中而呈环状，随损伤时间延长，阳性细胞数目增多，反应强度增加；伤后3～6h，延髓及桥脑中的SYN阳性物面积减少，其后恢复到正常水平，并持续到伤后24h。

At the same time,it also refracted the historical changes of more than thousand years tortuous development in Chinese society.

同时，这也折射出了千余年中国社会曲折发展的历史变迁。

Peripheral ring-type, tortuous beaded shape or serpiginous tubular shape enhancement were found in 8 cases. After analysis of follow-up MRI for 7 cases, a change in location and shape of lesions was found in 2 cases.

结果：增强扫描12例，病灶均显示强化，8例病灶呈环形、串珠状或匐行管状强化。7例MRI复查发现2例病灶强化的位置及形态有改变。

She was decommissioned in 1997, and the search for a final resting place has been tortuous.

克莱蒙梭号1997年就退役了。但为她（注1）寻找一个最终安息之地的过程却一波三折。
