目的 探讨眼底豹纹斑密度（FTD）及视盘旁萎缩弧（PPA）与眼轴长（AL）的相关性,为眼底定量化在儿童近视防控的应用提供科学依据。方法 本研究随机抽取广州市荔湾区两所小学三年级学生作为研究对象,在校园视力筛查的过程中同时采集AL、CR和眼底彩照。使用AI软件对眼底彩照进行量化分析,量化指标包括不同区域和范围的FTD及PPA面积大小,根据眼轴长度分为三组：A组（AL<23 mm）;B组（23 mm≤AL<24 mm）;C组（24 mm≤AL）。结果 共有398例右眼被纳入统计分析,年龄范围8~11岁,中位数是9岁,男性人数占55.1％。三组组间AL、AL/CR和SE比较均有统计学差异（P<0.05）。A组与B组相比,FTD在后极部整体范围、黄斑中心3 mm区域、黄斑中心3 mm区域上方区域具有统计学差异（P<0.05）,C组与B组相比,PPA面积及FTD在后极部整体范围、视盘为中心4.5 mm范围、黄斑为中心直径3 mm和6 mm范围均具有统计学差异（P<0.05）,Spearman相关性分析表明,AL与PPA（r=0.443）和FTD（r=0.322）呈正相关（P<0.001）。亚组相关性分析表明,A组仅黄斑为中心直径3 mm上方范围FTD与AL呈正相关（P=0.028）,B组PPA、黄斑中心直径3 mm及其上方范围FTD与AL呈正相关（P<0.05）,C组仅PPA与AL呈正相关（P=0.005）。结论 眼底定量对于儿童近视防控具有潜在价值,PPA和FTD与AL呈正相关性,不同区域和范围FTD与AL相关性具有一定差异性,黄斑中心直径3 mm范围及其上方范围与眼轴相关性最强。FTD在短眼轴阶段就可以作为生物标记物预测近视严重程度,而PPA主要在长眼轴阶段体现生物标记物的作用。

Objective To investigate the correlation between fundus tessellated density（FTD）and peripapillary atrophy（PPA）with axial length（AL）,providing a scientific basis for the application of fundus quantification in the prevention and control of myopia in children．Methods This study randomly selected third-grade students from two primary schools in Liwan District,Guangzhou City,as research subjects．Axial length（AL）,corneal radius（CR）,and fundus color photographs were collected simultaneously during the school vision screening process．AI software was utilized to perform quantitative analysis on the fundus color photographs,with quantification indicators including the area size of PPA and FTD in different regions and ranges．Subjects were divided into three groups based on axial length：Group A（AL<23 mm）;Group B（23 mm≤AL<24 mm）;Group C（AL≥24 mm）．Results A total of 398 right eyes were included in the statistical analysis,with an age range of 8 to 11,a median age of 9,and 55.1% were male．There were significant statistical differences in AL,AL/CR,and spherical equivalent（SE）among the three groups（P<0.05）．Compared with Group B,Group A showed significant statistical differences in FTD in the overall posterior pole,the 3 mm diameter area centered on the fovea,and the superior area of the 3 mm foveal center（P<0.05）．Compared with Group B,Group C showed significant differences in PPA area and FTD in the overall posterior pole,the 4.5 mm diameter area centered on the optic disc,and the 3 mm and 6 mm diameter areas centered on the fovea（P<0.05）．Spearman correlation analysis indicated that AL was significantly positively correlated with PPA（r=0.443）and FTD（r=0.322）（P<0.001）．Subgroup correlation analysis showed that in Group A,only the FTD in the superior area of the 3 mm diameter centered on the fovea was significantly positively correlated with AL（P=0.028）．In Group B,PPA and FTD in the 3 mm diameter and superior area centered on the fovea were significantly positively correlated with AL（P<0.05）．In Group C,only PPA was significantly positively correlated with AL（P=0.005）．Conclusions Fundus quantification holds potential value for the prevention and control of myopia in children．PPA and FTD show significant positive correlations with AL,with varying degrees of correlation in different regions and ranges of FTD with AL．The 3 mm diameter area centered on the fovea and its superior area have the strongest correlation with the eye axis．FTD can serve as a biomarker to predict the severity of myopia in the early stages of eye axis elongation,while PPA primarily manifests as a biomarker in the later stages of elongation．

目的 总结新生儿红斑狼疮(NLE)的临床特征和预后,提高对NLE的认识。方法 回顾分析2015年1月—2020年12月在广州市妇女儿童医疗中心住院诊治的19例NLE的临床资料,并进行文献复习。结果 收集19例新生儿红斑狼疮,男10例,女9例。皮肤受累者19例;心血管系统受累者7例,其中心电生理异常7例:Ⅲ度房室传导阻滞(AVB)2例,交界性心律1例,Ⅱ度AVB 2例,完全性左束支传导阻滞(CLBBB)1例,T波低平1例;扩张型心肌病(DCM)1例;房间隔缺损1例。血液系统受累者3例;消化系统受累者7例。患儿抗SSA或抗SSB阳性18人,抗核抗体阳性18人,dsDNA阳性2人,抗RNP阳性3人。孕母产前诊断系统性红斑狼疮4例,干燥综合征8例,未分化结缔组织病1例,无任何临床症状6例(有无诊断疾病),其中10例予糖皮质激素治疗。随访时间5月~62月,随访18例。心血管系统受累者的预后差异大,2例Ⅲ度AVB予心脏起搏器治疗,1例交界性心律者建议安装起搏器。1例CLBBB并DCM者的内科治疗效果差。2例Ⅱ度AVB 者无明显临床症状。T波低平者复查为正常。随访中未发现患儿及其母亲有新发自身免疫性疾病。结论 新生儿红斑狼疮临床表现以心血管系统受累为突出特征,其房室结外病变需引起关注。患儿和其母亲的长期随访非常重要。

Objective To summarize the clinical features and prognosis characteristics of neonatal lupus erythematosus (NLE).Methods The clinical data of 19 cases of NLE who were hospitalized in Guangzhou Women and Children's Medical Center from January 2015 to December 2020 were retrospectively analyzed,and the literature was reviewed.Results A total of 19 cases of neonatal lupus erythematosus were enrolled,10 males and 9 females.There were 19 cases of cutaneous lesions; 7 cases of cardiac system involvement,including 7 cases of electrophysiological abnormalities: 2 cases of third-degree atrioventricular block (AVB),1 case of junctional heart rhythm,2 cases of second-degree AVB,1 case of complete left bundle branch block (CLBBB),1 case of low T-wave.Dilated cardiomyopathy(DCM)was found in 1 case,and atrial septal defect was found in 1 case.There were 3 cases of blood system abnormalities and 7 cases of digestive system problems.Eighteen children were positive for anti-SSA or anti-SSB test,18 were positive for ANA,2 were positive for dsDNA,and 3 were positive for anti-RNP.Four cases of mother was prenatal diagnosed with systemic lupus erythematosus,8 cases of Sjgren's syndrome,1 case of undifferentiated connective tissue disease,and 6 cases without any clinical symptoms,among them,10 cases were treated with glucocorticoids.The follow-up time varied from 5 months to 62 months,and 18 cases were followed up.The prognosis of patients with cardiac system involvement varied greatly.Two patients with third-degree AVB were treated with pacemaker,and 1 patient with junctional rhythm was recommended to install pacemaker.The patient with CLBBB and DCM had poor outcome with medical treatment.Two patients with second-degree AVB had no clinical symptoms,and the low T-wave one returned to normal.During the follow-up,no new autoimmune diseases were found in the children and their mothers.Conclusions The clinical manifestations of neonatal lupus erythematosus are prominently characterized by involvement of the cardiovascular system,and the extranodal lesion need to be paid attention to.Long-term follow-up of children and their mothers is critically important.
