目的探讨血清维生素A、D水平与新生儿感染的严重程度及预后之间的关系。方法收集2020年4月至2022年4月苏州大学附属儿童医院新生儿科住院的82例新生儿感染性疾病患儿为观察组;根据新生儿危重病例评分将其分为极危重组(20例)、危重组(25例)、非危重组(37例);根据预后情况,将其分为死亡组(11例)和生存组(71例)。选取同期住院非感染新生儿80例作为对照组。比较观察组与对照组血清维生素A、D水平;比较新生儿感染不同疾病重症程度患儿血清维生素A、D水平;分析血清维生素A、D水平与新生儿感染疾病重症程度的相关性;分析新生儿感染患儿预后的影响因素;评估血清维生素A、D对新生感染患儿预后的预测价值。结果观察组维生素A、D水平低于对照组(P<0.05)。极危重组、危重组血清维生素A、D水平低于非危重组,极危重组血清维生素A、D水平低于危重组(P<0.05)。血清维生素A、D水平与新生儿感染疾病危重程度呈负相关(r=-0.458、-0.489,P<0.01)。死亡组降钙素原(PCT)、C反应蛋白(CRP)水平高于生存组,维生素A、D水平低于生存组(P<0.05)。PCT、CRP、维生素A、维生素D是新生儿感染预后的影响因素(P<0.05)。维生素A、D联合预测新生感染预后的曲线下面积高于各项单独预测。结论新生儿感染时血清维生素A、D水平与疾病严重及预后密切相关,并可以作为预测预后的有效指标。

Photodynamic therapy(PDT)is an emerging therapeutic strategy for hypertrophic scars(HS),which is heavily dependent on reactive oxygen species(ROS)***,the unsatisfactory delivery and excitation of 5-aminolevulinic acid(ALA,a commercial photosensitizer in dermatology)result in an insufficient ROS generation,and thus limit the clinical application of PDT treating HS(HS-PDT).Consequently,sophisticated transdermal co-delivery nanoethosomes(named A/A-ES)with ALA and Au nanotriangles(AuNTs)in cores are prepared via an in-situ seed-mediated growth method,and then applied to improve HS-PDT through localized surface plasmon resonance(LSPR)-enhanced ROS generation.A/A-ES display a satisfactory performance in co-delivery in HS tissue with sufficient protoporphyrin IX production and LSPR effect in cytoplasm,which is beneficial for ALA excitation as well as ROS *** vitrolvivo studies reveal that A/A-ES significantly improve HS-PDT in promoting to fibroblast apoptosis and collagen remodeling through LSPR-enhanced ROS ***,this study provides a feasible strategy that integrates transdermal delivery and LSPR to enable the beneficial effects of HS-PDT through boosting the delivery and excitation of ALA.

为克服运动目标检测中易出现的光照变化、遮挡、虚假目标等现象,提出了一种随机图像选取与自适应背景更新的运动物体检测方法。该方法从视频序列中随机选取一帧图像作为初始背景,根据变化标记矩阵对背景进行自适应迭代更新,以提取可靠的背景图像,实现运动物体的检测。实验结果表明,采用该算法提取的背景不存在混合现象,且在光照变化较大以及运动物体之间存在遮挡的情况下,能够构造出可靠的背景,检测出的目标物体清晰可见。
