It is found that the response of the rotation is similar for all possible ECW toroidal injection angles. The core toroidal rotation velocity increases in the co-current direction along with a rise in the plasma temperature and stored energy. The profile of the electron temperature, ion temperature and toroidal rotation velocity gradually become peaked.The change in toroidal rotation in the core increases with the ECW injection power. Different behavior is observed when the ECWs are injected into low hybrid current drive(LHCD) target plasmas, where the electron temperature and rotation profile become peaked, while the ion temperature profile flattens after ECW injection, suggesting different transport characteristics in energy and momentum.展开更多

文摘目的 探究维持性腹膜透析(MPD)患者肺动脉高压(PAH)与细胞外水(ECW)/身体总水(TBW)水平的关系。方法 回顾性分析2019年5月至2022年5月安徽医科大学第一附属医院收住院的125例MPD患者临床资料,根据超声心动图检查肺动脉压力值分为PAH组(肺动脉压力≥35 mm Hg)75例和非PAH组(肺动脉压力<35 mm Hg)50例,比较两组的一般资料、实验室指标、超声心动图参数、人体成分分析参数。采用线性回归分析、平滑曲线拟合、受试者工作特征(ROC)曲线等方式探讨MPD患者ECW/TBW水平与PAH的相关性。结果 PAH组和非PAH组的体重指数(BMI)、收缩压、血红蛋白(HGB)、脑钠肽(BNP)、细胞外水(ECW)/身体总水(TBW)、射血分数(EF)、左室质量分数(LVMI)差异均有统计学意义(P<0.05)。多因素logistic逐步回归分析结果显示,ECW/TBW(×10^(-2))[OR=1.127,95%CI:1.005~1.265,P=0.041]是MPD患者发生PAH的独立影响因素。以PAH为状态变量,ECW/TBW(×10^(-2))为检验变量绘制ROC曲线,ECW/TBW预测PAH发生的ROC曲线下面积为0.739,其临界点为47.1×10^(-2)。ECW/TBW(×10^(-2))每升高1×10^(-2),PAH发生率升高12.7%。结论 MPD患者的PAH发生与容量状态关系密切,ECW/TBW水平升高可导致PAH的发生。
