目的:探讨中心静脉压(CVP)指导慢性肾脏疾病(CKD)合并冠心病(CHD)患者水化对降低造影剂肾病(CIN)风险的临床效果。方法:选择于我院心内科接受经皮冠状动脉介入治疗(PCI)的CKD合并CHD患者149例作为前瞻性观察研究对象,随机分为CVP组(73例)和对照组(76例)。CVP组根据动态监测CVP的结果每小时精细地调整水化补液速度,对照组的水化补液速度为1ml·kg^(-1)·h^(-1)[左室射血分数(LVEF)0.05)。CVP组和对照组PCI后CIN的发生率分别为5.5%和11.8%,组间比较差异无统计学意义(P=0.169)。CVP组暴露于造影剂后48h内绝对肌酐(SCr)水平显著低于对照组[(-0.01±0.43)mg/dl∶(0.07±0.31)mg/dl,P=0.005]。在住院期间和手术后90d内,CVP组累积次要不良事件发生率为6.8%,对照组为18.4%,组间比较差异有统计学意义(P=0.034)。结论:CVP指导水化较标准水化方案并不能更好地降低CIN的发生风险。

针对半波长线路主保护面临全线速动性的问题,首先分析由超长线路距离导致的基于双端量纵联保护速动性受通信固有时延的制约和现有就地量主保护原理的局限性。在此基础上,结合波速度差单端测距原理和半波长线路故障传播特性分析,提出一种超高速测距式就地主保护新原理。提出通过比较线模行波和零模行波的到达时差判断故障发生距离的新判据,并结合行波方向判据形成主保护原理,实现线路全长范围内接地故障的准全线覆盖,与现有纵联类主保护相比,动作速度提高了1~2个周波。算例仿真验证了所提保护原理的有效性和优越性。

A new passive control approach,utilizing bionic slanting riblets,is employed to mitigate the flow close to the blade endwall in a linear cascade,and its effectiveness and mechanism in controlling corner separation are investigated through numerical *** slanting riblets are positioned at the endwall upstream of the cascade channel,and the influence of riblet height,yaw angle and relative position on the control of corner separation is *** findings indicate that the application of slanting riblets can efficiently counteract corner separation across the stable operational ***,the introduction of riblets with a height of merely 0.1 times the boundary layer thickness results in a significant reduction in total pressure loss by up to 14.53%,while simultaneously enhancing the static pressure coefficient by 21.74%.Flow analysis reveals that minute vortices produced within the riblet channels tend to coalesce,forming a potent large-scale vortex near the boundary layer's base *** phenomenon results in reduced additional losses compared to conventional vortex ***,the induced vortex promotes enhanced mixing between the mainstream flow and boundary layer,inhibiting the lateral displacement of low-energy fluids within the endwall boundary ***,this delays the onset of separation vortex formation and eliminates vortex rings in the corner region,ultimately enhancing the aerodynamic efficiency of the cascade.

Gastric cancer(GC) is a prevalent and lethal malignancy worldwide, and the 5-year survival rate is less than 30%. The absence of distinctive symptoms often leads to late-stage diagnosis, contributing to a grim prognosis. Early detection is pivotal for improving the survival rates and outcomes of GC patients. Traditional diagnostic methods, including gastroscopy and histopathological examination, are restricted in the early diagnosis of GC. Conventional protein biomarkers, such as carcinoembryonic antigen(CEA), carbohydrate antigen 19-9(CA19-9), and carbohydrate antigen 72-4(CA72-4), exhibit insufficient sensitivity and specificity for GC screening, which diminishes their clinical value. Recently, novel circulating biomarkers, such as circulating tumor cells(CTCs), circulating tumor cell DNA(ct DNA), and circulating free RNA(cf RNA), have emerged as promising candidates in the burgeoning field of liquid biopsy due to their superior sensitivity and specificity. This review focuses on the latest research on blood-based biomarkers for GC diagnosis and examines the clinical potentials and challenges associated with these emerging biomarkers.
