目的:探讨IL-12A和IL-12B基因多态性与江苏人群宫颈癌的遗传易感性的关系.方法:采用病例对照研究,对经组织学确诊的宫颈癌新发病例404例按年龄和城乡频数匹配正常对照404例,以聚合酶链式反应-限制性片段长度多态性(PCR-RFLP)方法对IL-12A基因的rs568408(3'UTR G>A)、rs2243115(5'UTR T>G)和IL12B基因的rs3212227(3'UTR A>C)进行多态性检测.比较不同基因型与宫颈癌发病风险的关系.结果:在调整年龄、城乡等因素后,携带IL-12A rs568408 GA/AA和IL-12Brs3212227 AC/CC突变基因型的个体发生宫颈癌的风险较携带IL-12A rs568408 GG和IL-12B rs3212227 AA野生基因型的个体分别增加了43%(调整OR=1.43,95%CI=1.06~1.93)和30%(调整OR=1.30,95%CI=0.97~1.75),并且该两位点之间存在基因一基因相乘交互作用(P=O.048),同时携带两个突变基因型的个体发生宫颈癌的风险增加了82%(调整OR=1.82,95%CI=1.28~2.57).分层分析表明.两基因位点的联合作用在早期官颈癌患者和多产的患者中更为显著.同时携带两个突变基因型并且活产数大于2的个体发生宫颈癌的危险增加6倍(调整OR=6.00,95%CI=2.86~12.56),并且存在显著的基因环境相乘交互作用(P=046).结论:IL-12A rs568408和IL-12B rs3212227基因多态性位点可能单独或共同影响江苏人群宫颈癌发病风险,并且与个体的活产数有关.  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
