Neutron-induced nuclear recoil background is critical to dark matter searches in the PandaX-4T liquid xenon *** this study,we investigate the features of neutron background in liquid xenon and evaluate its contribution in single scattering nuclear recoil events using three *** first method is fully based on Monte Carlo *** last two are data-driven methods that also use multiple scattering signals and high energy signals in the *** the PandaX-4T commissioning data with an exposure of 0.63 tonne-year,all these methods give a consistent result,i.e.,there are 1.15±0.57 neutron-induced backgrounds in the dark matter signal region within an approximated nuclear recoil energy window between 5 and 100 keV.

补肾安胎冲剂对人胎盘微血管内皮细胞VEGF/PI3K/Akt信号通路表达的影响

引用

环球中医药 2024年第12期17卷 2441-2448页

作者：李元琪李伟莉储继军余欣慧吴俊陆莎莎安徽中医药大学第一附属医院妇产科蒙城县中医院妇科

目的基于VEGFR-2沉默探讨补肾安胎冲剂(后文简称BSAT)对人胎盘微血管内皮细胞(human placental microvascular endothelial cells, HPMVECs)的影响，通过血管内皮生长因子(vascular endothelial growth factor, VEGF)/磷脂酰肌醇3激酶(phosphoinositide 3-kinase, PI3K)/丝苏氨酸蛋白激酶(protein kinase B,Akt)通路探索其治疗复发性流产(recurrent spontaneous abortion, RSA)的作用机制。方法在体外构建人胎盘微血管内皮细胞，随后采用转染小干扰RNA(siRNA)技术沉默VEGFR-2基因表达，并给予补肾安胎冲剂含药血清或空白血清干预，将人胎盘微血管内皮细胞分为空白血清组(PBS+空白血清)、siRNA空白血清组(PBS+VEGFR-2 siRNA+空白血清)、siRNA NC空白血清组(PBS+NC siRNA+空白血清)、siRNA药物血清组(PBS+VEGFR-2 siRNA+BSAT含药血清)、药物血清组(PBS+BSAT含药血清)予对应处理，实时荧光定量PCR、免疫荧光法及Western blot分别检测VEGF、VEGFR-2、PI3K、Akt mRNA及蛋白表达，观察在VEGFR-2基因沉默时，补肾安胎冲剂是否能通过PI3K/Akt通路介导血管新生。结果空白血清组和siRNA NC空白血清组相比，VEGF、VEGFR-2、PI3K、Akt mRNA及蛋白无明显差异(P>0.05);药物血清组细胞VEGF、VEGFR-2、PI3K、Akt mRNA及蛋白的表达明显高于空白血清组(P<0.05)。与空白血清组相比，siRNA空白血清组VEGF、VEGFR-2、PI3K、Akt mRNA及蛋白的表达明显下降(P<0.01)。siRNA药物血清组与siRNA空白血清组相比，VEGF、VEGFR-2、PI3K、Akt有明显上升(P<0.01),补肾安胎冲剂能显著提高VEGF/PI3K/Akt的低表达。结论补肾安胎冲剂通过激活HPMVECs中VEGFR-2,靶向上调PI3K/Akt表达，介导血管新生，促进母胎界面血管重构，从而对RSA发挥治疗作用。

关键词：补肾安胎冲剂复发性流产胎盘微血管内皮细胞磷脂酰肌醇3激酶/丝苏氨酸蛋白激酶信号通路血管内皮生长因子
