儿童孤立性直肠溃疡综合征（SRUS）是一种较为罕见的慢性直肠疾病,儿童发病率低且缺乏明确统计学数据。该病主要表现为便血、排黏液便和排便不尽感,临床诊断较为困难,常易误诊为其他疾病。其发病机制尚不明确,可能与排便习惯异常、直肠黏膜异常、血管异常以及遗传易感性等多种因素有关,其中 CHEK2 基因的 p.H371Y 突变可能在发病机制中起关键作用。诊断需综合病史、体格检查以及排粪造影、超声内镜、肠镜检查与组织病理活检等多种辅助检查手段。治疗上目前尚无统一指南,主要包括改善饮食和排便习惯、生物反馈治疗、药物治疗、内镜下治疗和外科手术治疗等,但总体治疗难度较大且复发率较高。本文对儿童 SRUS 的流行病学、发病机制、临床表现、诊断和治疗等方面的研究进展进行综述,旨在提高临床医师对该病的诊疗水平,为未来进一步的研究提供参考依据。

       Solitary rectal ulcer syndrome（SRUS）in children is a chronic and benign disease of the rectum characterized by ulcers. The clinical incidence of SRUS in children is not high, but it is prone to misdiagnose and miss diagnosis,which can delay the optimal treatment opportunity. This article reviews the research progress on the epidemiology,pathogenesis, clinical manifestations, diagnosis and treatment of SRUS in children, aiming to improve the diagnostic and therapeutic level of clinicians.

       目的   分析原发性肾病综合征（PNS）患儿在糖皮质激素（激素）治疗后淋巴细胞亚群及免疫因子的水平变化，以探讨PNS耐药机制。方法   选取PNS患儿共71例，正常对照组108例，收集PNS患者在激素治疗前、后及正常对照组儿童的淋巴细胞亚群［CD4⁺ 、CD8⁺ 、CD4⁺ /CD8⁺ 、CD19⁺ 和自然杀伤（NK）细胞］及免疫因子水平，并分析激素治疗后激素敏感患儿和激素耐药患儿相关指标的差异。结果  PNS患儿淋巴细胞亚群及免疫因子水平异常，激素治疗后PNS患儿总免疫球蛋白E（IgE）水平［767.50（270.25，1 937.50）IU/mL vs 311.00（62.70，757.00）IU/mL］（P=0.008）下降，而CD4⁺ T细胞比例［（33.88±7.42）% vs（38.25±7.16）%］（P=0.004）升高，激素治疗敏感患儿NK细胞比例高于激素治疗耐药患儿［（8.39±4.60）% vs（4.72±1.99）%］（P=0.034），IgE水平低于耐药患儿［311.00（62.70，633.00）IU/mL vs783.00（88.05，1 290.00）IU/mL］（P＜0.001）。结论  PNS患儿淋巴细胞亚群分布及免疫球蛋白水平异常，激素治疗可影响患儿CD4⁺ T细胞比例及IgE水平，并且NK细胞比例和IgE水平与患儿激素耐药相关。

       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.
