血浆置换联合双重血浆分子吸附系统人工肝治疗肝衰竭高胆红素血症患者疗效研究

目的：探讨血浆置换（plasma exchange,PE）联合双重血浆分子吸附系统（double plasma molecular adsorption system,DPMAS）即PE+DPMAS治疗前与第1次、第2次治疗后肝衰竭高胆红素血症患者的临床疗效。方法：采用回顾性分析方法，选取2020年1月至2022年5月于遵义医科大学附属医院就诊的57名肝衰竭患者，根据采取的人工肝治疗模式不同将接受PE治疗的24例患者纳入对照组，接受PE+DPMAS的33例患者纳入实验组。收集2组治疗前与2次治疗后肝衰竭高胆红素血症患者的临床资料，观察并对比2组治疗前后肝功能、凝血功能、营养状况等指标变化情况。结果：实验组与对照组治疗前总胆红素（total bilirubin,TBil）、丙氨酸转氨酶（alanine transaminase,ALT）、天冬氨酸转氨酶（aspartate aminotransferase,AST）、球蛋白（globulin,Glb）、纤维蛋白原（fibrinogen,FIB）与第1次、第2次治疗后比较差异均有统计学意义（P<0.05），但实验组治疗比对照组治疗能更...

Clinical effect of plasma exchange combined with double plasma molecular adsorption system in artificial liver support therapy for patients with liver failure and hyperbilirubinemia

In order to address the issue of wavelength selection in offshore visible light communication, this study analyzed the background light model and atmospheric turbulence channel model that impacted marine visible light communication. The key factors that influenced the quality of visible light communication were identified. Simulations of the visible light communication system under three different conditions were also conducted. These simulations provided insights into the correlation between the light source wavelength and the bit error rate. Specifically, the correlation was examined under varying communication distances, refractive index structure parameters, and field angles. The obtained results serve as a foundation for selecting the appropriate light source wavelength in offshore visible light communication.
