VEGF和NOS在口腔鳞癌组织中的表达

目的:研究口腔鳞癌组织血管内皮生长因子(VEGF)、诱导型一氧化氮合酶(iNOS)、内皮型一氧化氮合酶(eNOS)的表达与癌细胞增殖的相关性。方法：应用免疫组化方法检测64例口腔鳞癌手术切除标本VEGF、iNOS、eNOS和增殖细胞核抗原(PCNA)的分布及表达。结果：①39例(60.94％)口腔鳞癌组织表达VEGF，42例(65.63％)表达iNOS；45例(70.31％)表达eNOS；②VEGF与iNOS的表达具有明显相关性，VEGF与eNOS的表达无明显相关性；③表达VEGF的口腔鳞癌PCNA标记指数(PLI)明显高于不表达VEGF的口腔鳞癌；表达iNOS的口腔鳞癌PLI明显高于不表达iNOS的口腔鳞癌。表达eNOS的口腔鳞癌PLI与不表达eNOS的口腔鳞癌无显著性差异(P＞0.05)。结论：①VEGF与iNOS的表达具有明显相关性，说明iNOS在VEGF的生成和发挥作用过程中起重要作用；②PLI随着VEGF和iNOS表达的增加而增加；提示二者对口腔鳞癌细胞增殖具有促进作用。     

食管造影及温度监测指导环肺静脉消融治疗心房颤动

Objective Because of the severe consequences of an atrial esophageal fistula,it is vital to avoid this complication. The most safe way is to avoid ablating the segment of esophagus behind left atrium (LA). What we do is to image the relationship of esophagus to posterior LA wall and real-time esophageal tem-perature monitoring to ablate the posterior LA wall. Methods Sixty-four patients with paroxysmal atrial fibrilla-tion (PAF) were enrolled to pulmonary veins (PV) isolation. Swallowing a radiocontrast agent at the same time when imaging of LA to observe the relationship of esophagus to posterior LA wall and according to the different relationship between the segment of esophagus behind LA and PV, the esophagus were divided into type Ⅰ , type Ⅱ and type Ⅲ. A esophageal temperature probe was inserted and advanced into the esophagus directly posterior to the LA. Three steps ablation strategy and real-time esophageal temperature monitoring were applied to guide the PV isolation. The procedure was interrupted when the esophageal temperature was 39℃ until] the tempera-ture renormalized and ended when PV were isolated. Results There were 48 type ⅠI , 11 type Ⅱ and 5 type Ⅲ esophagus in the 64 patients. After three steps ablation,all PV isolations were completed. Only 18.8% of the patients needed to ablate the posterior LA close to the esophagus. Conclusion Only one PV ostiolum close to the posterior LA wall in most PAF patients and many of them can achieve complete PV isolation without ablating the posterior LA close to esophagus which could minimize the risk of esophageal injury dramatically.
