Quantitative real-time PCR was used to evaluate the transcription levels of IL-4, IL-5, IL-13, IL-4 receptor α (IL-4Rα), transforming growth factor-β receptor Ⅰ (TGF-βRⅠ) and sex-determining region Y(SRY)-box 4 (SOX4) in CD4+ T cells.Plasma concentrations of IL-4 and transforming growth factor-β(TGF-β) were measured by enzyme-linked immunosorbent assay. \u0000 \u0000 \u0000Results \u0000(1)Compared with control group, the proportion of Th2 cells, expression levels of Th2-associated cytokines (IL-4, IL-5 and IL-13) and histone H4 acetylation levels associating with IL-4 promoter and Va enhancer, increased remarkably during acute KD(all P<0.05), and restored after IVIG therapy(all P<0.05). Meanwhile, all the former items in KD patients with coronary artery lesions (CAL) were higher than those in patients with non-coronary artery lesions (NCAL) (all P<0.05).

Positive correlations between binding abilities of p300 with IL-4 (promoter and Va enhancer) and the expression of IL-4 promoter and Va enhancer were detected in patients with acute KD (r=0.72, 0.43, all P<0.05). Furthermore, binding abilities of p300 and CBP with IL-4 promoter and Va enhancer in CAL group were higher than those in NCAL group (all P<0.05).

Among 24 cases who underwent CSF detection, 10 patients (41.7%) had slightly increased white blood cells, 2 patients (8.3%) had elevated protein, 6 patients (25.0%) had positive MOG antibody, and CSF-restricted oligoclonal band was negative in all 24 patients.Twenty-five cases (89.3%) showed brain magnetic resonance imaging (MRI) abnormalities, including cerebral white matter (20/28 cases), cerebellum (10/28 cases), cerebral gray matter (9/28 cases), thalamus/basal ganglia (6/28 cases), brainstem (6/28 cases), optic nerve (5/28 cases), and corpus callosum (4/28 cases).

There were significant differences in sex ratio, onset age, course of disease, inducement, Addis count of urinary red cells, 24-hour proteinuria, blood urea nitrogen, serum creatinine, serum albumin and serum IgA levels among different clinical manifestations (all P< 0.05). Pathological grouping indicated that there were significant differences in sex ratio, onset age, course of disease, family history, Addis count of urinary red cells, 24-hour proteinuria, blood urea nitrogen, serum creatinine, serum albumin, serum IgA and C3 levels among different pathological groups (all P< 0.05). The BP neural network prediction model was then constructed based on the above indicators, and the accuracy of the prediction model was measured to be 61.19% by using the leave one out method. \u0000 \u0000 \u0000Conclusions \u0000By comparing the differences of various indicators under different clinical manifestations and pathological types, a BP neural network prediction model for renal pathology in children with hematuria as the main manifestation is established.The model can accurately predict renal pathology with the help of related indicators, and provides a basis for determining the time of kidney biopsy. \u0000 \u0000 \u0000Key words: \u0000Hematuria; Renal pathology; BP neural network; Prediction","PeriodicalId":9843,"journal":{"name":"中华实用儿科临床杂志","volume":"35 1","pages":"365-369"},"PeriodicalIF":0.0,"publicationDate":"2020-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48174681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
