CD4+ cells as a potential biomarker for cytomegalovirus retinitis in children with acute lymphocytic leukemia

引用

Chinese Medical Journal 2019年第3期132卷 356-359页

作者： jian-cang wang Fei-Fan Du Ming Su Xiao-Ge Yang Mei-Jie Quan Xiao-Ying Zhai Department of Ophthalmology Hebei Children's HospitalHebei Medical UniversityShijiazhuangHebei 050031China Department of Hematology Hebei Children's HospitalHebei Medical UniversityShijiazhuangHehei 050031China

To the Editor: Infection is one of the causes of death after chemotherapy in children with leukemia. About 20% to 30% acute lymphocytic leukemia (ALL) patients die from infection after chemotherapy.[1] Patients with immune deficiency, under chemotherapy, or treated with immunosuppressor are more inclined to be infected with human cytomegalovirus (HCMV) which leads to severe systematic disorders.[2] Cytomegalvirus retinitis (CMVR) is a major sight threatening disease which mainly occurs in patients with immune deficiency and results in blindness if treatment is delayed. The decrease of CD4+ T cells has been related to CMVR in immune deficiency syndrome like AIDS.[3] However, little is known about the relation between the level of T cells with different markers and the onset of CMVR in ALL patients under chemotherapy. Therefore, this study was designed to investigate the diagnostic value of T cells with different markers for cytomegalovirus retinitis after chemotherapy in patients with ALL.

盲源分离(BSS)算法通常需预先假设源信号的概率密度函数(PDF),并由此获得关键的激活函数(AF),进而从混合信号中分离出源信号。但若假设的概率密度函数与真实概率密度函数差异较大,源信号将不能被正确分离。基于峰度的盲源分离开关算法无需假设源信号的概率密度函数,可直接对独立分量分析(ICA)中的激活函数进行自适应学习。计算机仿真证明,该算法可有效进行盲源分离。
