Objective To experimentally study the expression of vascular endothelial growth factor after transarterial chemoembolization and its relationship with vasculogenesis and tumor cell proliferation.

目的 探讨大鼠移植性肝癌经动脉化疗栓塞后血管内皮生长因子的表达及其与血管生成和细胞增殖间的关系。

Objective To observe the clinical effect in treating metastatic liver cancer in artery interventional and vein chemotherapy with oxaliplatin, 5-fluorouracil deoxyribonucleoside and citrovorum factor, mitomycin +lipiodol.Methods 38 non-operable cases of metastatic liver cancer were given transfemoral artery chemoembolization, catheterical head was placed into tumors feeding artery(common hepatic artery, left of right hepatic artery, hepatic segmental artery), veinous chemotherapy in the next day.

目的 观察奥沙利铂(Oxaliplatin， L-OHP)联合氟尿嘧啶脱氧核苷、亚叶酸钙、丝裂霉素+超液化碘油动脉介入+静脉化疗双通路对转移性肝癌的临床疗效方法不能手术的转移性肝癌38例，经皮股动脉穿刺插管至腹腔动脉，并超选至肿瘤的供血供氧血管后灌注化疗药并栓塞，于次日再给予静脉化疗。

Results:Adhesive role of WAB tissues adhesives was worst. Fibrin Sealant's adhesive pressure was 50 pbsi in 5 min, no function to balloon catheter and fiberscape.

结果 ：WAB生物胶作用差，纤维蛋白封闭剂 5min时粘合力为 5 0pbsi，而且不会对导管有明显的粘合作用，而血管栓塞剂 5min后粘合作用为 70pbsi，但导管易与肺及支气管粘合。

Methods:Using Japan Shimadzu 1250Ma CCD DSA X machine,4F RH or 4F YASHIRO catheter and 3F SP microcatheter were employed in superselective chemoembolization for feeding artery of lung cancer and the metastases tumor with rich blood feeding in lung with lipiodol and 2～3 species chemodrug.The period of repetitive treatment was 4～6weeks.After treatment,the change of the symptoms,images of neoplasm and the survival rates were observed.

材料与方法：在日本岛津1250MA CCD数字减影X光机的引导下，使用4F RH或4F YASHIRO超滑导管及3F超滑微导管实施超选择性肿瘤滋养动脉插管，以超液态碘油及2～3种化疗药物对临床及病理证实的原发性支气管肺癌、肺富血供性转移瘤灶实施完全性化疗栓塞，重复治疗间隔时间4～6周，术后随访观察临床症状的变化、肿瘤的影像学改变、生存率等。

In fact, the cause of paradoxical gas embolism in this case was still unknown.

事实上，这个病例发生paradoxical二氧化碳栓塞的原因仍然是未知不明的。

The diagnosis of arterial gas embolism depends mainly on the medical history.

动脉气体栓塞症的诊断，主要取决於病史。

There should be a risky event preceeding to the compatible symptoms or signs of arterial gas embolism.

也就是，发病前应该有会导致动脉气体栓塞症的危险事件或处置，以及症状或病徵需与疾病的进程相吻合。

Pulmonary embolism ; Blood gas analysis ; Helix CT

肺栓塞；血气分析；螺旋CT

The main pathogenesis of arterial gas embolism is the obstructive effect of gas bubble in the end artery leading to tissue hypoxia and ischemia.

动脉气体栓塞症的主要致病机转，是气泡阻塞在末端动脉，导致组织缺氧和缺血。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
