EML4-ALK是肺癌诱发基因之一,属于融合基因,2007年由日本学者首次报道。在非小细胞肺癌(non-small-celllung carcinoma,NSCLC)患者中EML4-ALK表达阳性率约为3%~8%。EML4-ALK融合基因存在多种不同结构的变异体,其中3种变异体占大多数,其他变异体相对较少。目前尚无标准的、快速简便的检测EML4-ALK的方法,使其临床应用推广受到限制,有待进一步研究。新近的临床研究发现,EML4-ALK阳性率和患者是否吸烟高度相关,也与年龄、腺癌以及表皮生长因子受体(epidermal growth factor receptor,EGFR)和KRAS基因是否突变等因素相关。其中不吸烟或轻度吸烟的NSCLC患者EML4-ALK阳性率高达9.4%,而在吸烟的患者中其阳性率只有2.9%,两者存在显著性差异。EML4-ALK表达阳性与EGFR、KRAS突变呈负相关。在NSCLC患者中EML4-ALK表达和EGFR、KRAS突变很少同时存在。EML4-ALK的抑制剂TAE684和PF02341066等目前已进入Ⅲ期临床试验,前期研究取得了较好的疗效。EML4-ALK现已成为NSCLC治疗的新靶点,EML4-ALK抑制剂为肺癌的个体化治疗提供了新的可选择方案,也可作为不能耐受化疗的患者的治疗药物。  相似文献

目的:探讨EML4-ALK融合基因在新疆维吾尔族NSCLC患者中的表达及其对预后的影响.方法:应用免疫组化法及FISH法检测新疆维吾尔族和汉族NSCLC患者EML4-ALK融合基因表达情况,并分析新疆维吾尔族NSCLC患者EML4-ALK融合基因表达与临床病理特征的关系及对预后的影响.结果:新疆维吾尔族、汉族NSCLC患者EML4-ALK融合基因表达阳性表达率分别为21.00%、9.00%,经统计学检验发现不同民族NSCLC患者EML4-ALK融合基因阳性表达率存在统计学差异,新疆维吾尔族NSCLC患者EML4-ALK融合基因阳性表达率明显高于汉族;新疆维吾尔族NSCLC患者EML4-ALK融合基因表达与年龄、性别、吸烟、临床分期、病理切片类型有关,年龄≤55岁、女性、不吸烟、临床分期高、病理切片类型为腺癌的新疆维吾尔族NSCLC患者EML4-ALK融合基因阳性表达率较高;EML4-ALK融合基因阳性表达的新疆维吾尔族NSCLC患者中位总生存时间为22个月(95%CI,11个月~26个月),不同EML4-ALK融合基因表达总生存时间没有统计学差异.结论:新疆维吾尔族NSCLC患者EML4-ALK融合基因阳性表达率较高,多见于年龄≤55岁、女性、不吸烟、临床分期高、病理切片类型为腺癌者,但EML4-ALK融合基因还不能作为独立的预后影响因素.  相似文献

Objective: To evaluatel the value of D-dimers in patients with acute aortic dissection (AAD). Methods: This study consisted of 16 patients with AAD and 27 non-AAD patients. Serum D-dimets were measured by Sta-Liatest D-DI immunoturbidimetric assay. Results: D-dimer level was higher (P < 0.001) in patients with AAD(7.91 ± 5.52 μg/ml) than that in non- AAD group(1.57±1.24 μg/ml). D-dimer was positive (>0.4 μg/ml) in all patients with AAD and in 10 control group patients (37%). Among patients with acute AAD, D-dimers tended to be higher in Stanford A than in Stanford B (8.67 ± 4.31 μg/ml vs. 3.24±1.27 μg/ml, P <0.01). D-dimer values tended to be higher in more extended disease(3.84 ± 1.65 μg/ml, 8.57 ± 3.58 μg/ml and 11.87 ± 5.69 μg/ml in thoracic aorta, thoracic and abdominal aorta, thoracic and abdominal aorta and iliacal arteries, respectively, P < 0.05 for both 8.57 ± 3.58 and 11.87 ± 5.69 vs. 3.84 ± 1.65 ). Including the control group into the analysis, we found a sensitivity of 100%, a negative predictive value of 100%, and a specificity of 66% and a positive predictive value of 64% for D-dimer in diagnosis of AAD in our patients with suspected AAD. Conclusion: D-dimer was elevated in patients with AAD. A negative D-dimer test result could be useful in excluding AAD.  相似文献

Objective: To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods: SD rats served as both donors and recipients. 4℃ sodium lactate Ringer's was infused from portal veins to donated livers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava (IVC) inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results: Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion: This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment.  相似文献

Objective To observe blood pressure change with age in salt-sensitive teenagers whose salt sensitivity were determined by repeated testing.Methods Salt sensitivity was determined through intravenous infusion of normal saline combined with volume-depletion by oral diuretic furosemide in 55 teenagers. After five years, salt sensitivity was re-examined and subject blood pressure was followed up. Blood pressure changes in salt-sensitive teenagers were compared to that of non-salt sensitive teenagers over five years.Results After 5 years, the repetition rate of salt sensitivity determined by intravenous saline loading is 92.7%. In teenagers with salt sensitivity on the baseline, both the systolic blood pressure increments and increment rates were much higher than non-salt sensitive teenagers (12.7±12.1 mmHg vs. 2.8±5.2 mmHg, P< 0.01; 12.2%± 12.0% vs. 2.5% ±4.4%, P< 0.001,respectively). There was a similar trend for diastolic blood pressure (8.4 ± 6.4 mmHg vs. 3.7 ± 6.4 mmHg, P = 0.052; 13.2% ±10.6 % vs. 6.8%± 10.1%, P = 0.053, respectively).Conclusions Salt sensitivity determined by intravenous saline loading showed good reproducibility. Blood pressure increments with age were much higher in salt-sensitive teenagers than non-salt sensitive teenagers, especially in terms of systolic blood pressure.  相似文献

Objective:To investigate the influences of urapidil and nicardipine on rabbit sinus function,atrio-ventricular node function and hemodynamics.Methods:Thirty-two Angora's rabbits were selected and randomly divided into four groups.U1 group:urapidil 0.25 mg/kg;U2 group:urapidil 0.5 mg/kg;N1 group:nicardipine 10 μg/kg;N2 group:nicardipine 20 μg/kg.All these medicine were administrated within 30 seconds.Measurements were taken before and after the administration of urapidil or nicardipine for the following data:mean blood pressure(MAP),heart rate(HR),sino-atrial conduction time(SACT),maximal sinoatrial recovery time(SNRTmax)corrected sinus node recovery time(CSNRT),index of sinus node recovery time(SNRTI),Wenckebach A-V conduction frequency (WB),and P-R interval.Results:Significant MAP and HR changes were identified in all of the four groups before and after administration of both urapidil and nicardipine.No significant changes could be found in the rest of the parameters.Intergroup analysis showed that SACT and CSNRT of N1 and N2 groups were shorter than those of the U2 group(P<0.01);the MAP decreased(P<0.01)and the HR increased drastically(P<0.01).Conclusions:Neither urapidil(0.25 mg/kg,0.5 mg/kg)nor nicardipine(10μg/kg,20μg/kg)has any significant influence on rabbit sinus function or rabbit atrio-ventricular node function.Nicardipine could be a better choice than urapidil for parafunctional sinus node patients.  相似文献
