目的研究促甲状腺激素(TSH)及甲状腺自身抗体与分化型甲状腺癌(DTC)的关系。方法选择本院2022年1月-2022年12月收治100例甲状腺结节患者,根据“术后病理学结果”分良性组(良性甲状腺结节),恶性组(DTC患者)各50例,均行TSH、甲状腺自身抗体检测,检测结果分析。结果两组比较TPOAb指标无差异,P>0.05;较良性组,恶性组TSH、TgAb指标更高;恶性组TSH增高异常率(20.00%)高于良性组(8.00%);恶性组TgAb阳性率(16.00%)高于良性组(4.00%),χ^(2)=11.259,6.327;导致DTC疾病独立危险因素是TSH增高、TgAb阳性,P<0.05(具有统计学意义)。结论TSH增高、TgAb阳性是造成DTC疾病的独立危险因素,对疾病鉴别诊断有一定价值,为后期诊疗提供数据支持、改善预后,值得推崇。

A suitable channel structure can lead to efficient gas distribution and significantly improve the power density of fuel *** this study,the influence of two channel design parameters is investigated,namely,the ratio of the channel width to the bipolar plate ridge width(i.e.,the channel ridge ratio)and the channel *** impact of these parameters is evaluated with respect to the flow pattern,the gas composition distribution,the temperature field and the fuel cell output *** results show that a decrease in the channel ridge ratio and an increase in the channel depth can effectively make the distributions of velocity,temperature and concentration more uniform in each channel and improve the output capability of the fuel *** increase in the channel ridge ratio and depth obviously reduces the flow resistance and improves the flow characteristics.
