ABSTRACT
Objective:To explore the risk factors of rotavirus enteritis with myocardial injury and the value of establishment of a risk map model.Methods:The clinical data of 247 patients with rotavirus enteritis in Dongfeng Hospital of Hubei University Medicine from January 2017 to December 2018 were retrospectively analyzed. They were divided into the myocardial injury group(158 patients) and the non-myocardial injury group(89 patients) according to the happening of myocardial injury, and the basic information of all patients was retrieved. Independent risk factors for mycotic enteritis with myocardial injury were analyzed by univariate analysisand multiple Logistic regression analysis.A nomogram prediction model was established using R software, and the accuracy and discrimination of the nomogram model were verified.Results:The univariate analysis showed that the age, vomiting, severe dehydration, electrolyte disturbance, acidosis, and abnormal electrocardiogram were the risk factors of rotavirus enteritis with myocardial injury ( P < 0.05). The multivariate Logistic regression analysis showed that the age ranged between 6 months and 1 year ( OR = 1.989, 95% CI 1.123-3.524), vomiting ( OR = 2.509, 95% CI 1.405-4.480), severe dehydration ( OR = 2.782, 95% CI 1.083-7.142), electrolyte disturbance ( OR = 1.655, 95% CI 1.011-3.007) and acidosis ( OR = 2.417, 95% CI 1.348-4.332) were independent risk factors for rotavirus enteritis with myocardial injury ( P < 0.05). The collinear chart prediction model established showed that it had good prediction ability. At the same time, the collinear chart model was verified using Bootstrap internal verification method. The C-index index was 0.736 (95% CI 0.704-0.768) indicated that the column of the line graph model had good accuracy and discrimination. Conclusions:Ages from 6 months to 1 year, vomiting, severe dehydration, electrolyte disturbance, and acidosis are independent risk factors for rotavirus enteritis with myocardial injury. The establishment of a related nomogram predictive model is helpful for clinical personnel to screen high-risk populations and has guiding significance in prevention and treatment measures.
ABSTRACT
Objective To investigate the clinical value of perinuclear antineutrophil cytoplasmic antibody (p-ANCA) and fecal calprotectin in predicting the severity of ulcerative colitis (UC) in children.Methods One hundred children with UC from March 2014 to March 2019 in Affiliated Dongfeng Hospital,Hubei University of Medicine were selected.According to the endoscopic severity index of ulcerative colitis (UCEIS),the children were divided into remission stage (29 cases);active stage (71cases),among whom 43 cases were mild-moderate,and 28 cases were severe.The serum levels of interleukin-6 (IL-6),procalcitonin (PCT),C-reactive protein (CRP),erythrocyte sedimentation rate (ESR),albumin,platelet,hemoglobin,white blood cell and p-ANCA were detected,and the fecal calprotectin was detected.The clinical value of each index in predicting the severity of UC was determined by receiver operating characteristic (ROC) curve.Results The course of disease,IL-6,PCT,CRP,ESR,p-ANCA and calprotectin in remission stage children were significantly lower than those in active stage children:(3.14 ± 1.25) years vs.(3.73 ± 0.89) years,(10.08 ± 4.40)/μg/L vs.(15.84 ± 3.22) μg/L,(1.02 ± 0.38) μg/Lvs.(1.38 ± 0.43) μg/L,(15.92 ± 6.13) mg/L vs.(24.30 ± 6.06) mg/L,(14.75 ± 6.42) mm/1 h vs.(25.31 ± 6.98) mm/1 h,(17.19 ± 4.76) U vs.(28.01 ± 6.12) U and (504.82 ± 127.46) μg/g vs.(717.04 ± 142.30) μg/g,and there were statistical differences (P＜0.05 or ＜0.01).The IL-6,CRP,ESR,white blood cell,p-ANCA and calprotectin in mild-moderate children were significantly lower than those in sever children:(14.56 ± 2.72) μg/L vs.(17.82 ± 2.93) μg/L,(22.01 ± 5.32) mg/L vs.(27.83 ± 5.46) mg/L,(22.31 ± 4.46) mm/1 h vs.(29.91 ± 7.70) mm/1 h,(7.33 ± 1.33) × 109/L vs.(8.38 ± 1.90) × 109/L,(25.52 ± 5.22) U vs.(31.83 ± 5.44) U and (632.80 ± 82.51) μg/g vs.(846.42 ± 11.10) μg/g,and there were statistical differences (P＜0.01 or ＜:0.05).Pearson correlation analysis result showed that,in active children,the UCEIS had high positive correlation with fecal calprotectin (r =0.707,P＜0.01),mild positive correlation with p-ANCA,ESR,IL-6,CRP and albumin (r =0.660,0.650,0.626,0.592 and 0.486;P＜0.01),and low positive correlation with PCT and white blood cell (r =0.362 and 0.245,P＜0.01 or ＜0.05).ROC curve analysis result showed that the optimal cut-off value of p-ANCA was 23.40 U,and the area under curve (AUC) in diagnosis of active stage UC was maximum (0.923),with a specificity of 93.1％ and a sensitivity of 78.9％;the optimal cut-off value of fecal calprotectin was 732.69 μg/g,and the AUC in diagnosis of active stage UC was maximum (0.937),with a specificity of 93.0％ and a sensitivity of 92.9％.Conclusions Serum p-ANCA is useful for UC disease activity diagnosis in children,while fecal calprotectin is independent predictor of the severe of UC.
ABSTRACT
Objective To investigate the peripheral blood mucosa-associated constant T cell (MAIT) expression in children with bronchial asthma and its relevance to severity.Methods Ninetyeight children with bronchial asthma who were treated in Affliated Dongfeng Hospital from May 2016 to May 2019 were selected as the asthma group.Another 60 healthy children who underwent health checkup during the same period were as control group.The levels of MAIT were detected by flow cytometry analyzer using BD FACSAria Ⅱ flow cytometry,and the lung function was detected by Yage lung function tester.The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficacy of peripheral blood MAIT for bronchial asthma.Pearson analysis was used to examine the relationship between MAIT cells and pulmonary function.Results There were no significant differences in the general data of gender,age,and body mass index between the two groups (P ＞ 0.05).The asthma control test (ACT) score,the percentage of first second forced expiratory volume occupied estimated value (FEV1％),the percentage of first second forced expiratory volume occupied forced vital capacity (FEV1/FVC),the percentage of peak expiratory flowoccupied estimated value (PEF),and MAIT cells in asthma group were significantly lower than those in control group (P ＜ 0.05).Serum MAIT identified bronchial asthma and healthy controls with an area under curve (AUC) of 0.900,with a sensitivity of 82.65％,and a specificity of 85.00％.Serum MAIT identified the mild-sustained group and the healthy control group with an AUC of 0.910,with a sensitivity of 94.64％,and a specificity of 81.67％.Correlation analysis showed that MAIT cells in children with bronchial asthma were significantly positively correlated with pulmonary function indexes such as FEV1％,FEV1/FVC and PEF (r =0.159,0.222,0.213,P ＜ 0.05).Conclusions The peripheral blood MA1T in children with bronchial asthma is significantly reduced,which is related to the levels of lung function indicators.MA1T can be used as one of the indicators for the diagnosis and clinical prognosis of patients with bronchial asthma.

ABSTRACT
Objective To investigate the diagnostic value of lactate dehydrogenase (LDH) isoenzymes in children with refractory mycoplasma pneumoniae pneumonia (RMPP). Methods One hundred and forty-seven children with mycoplasma pneumoniae pneumonia (MPP) in Children′s Medical Center, Dongfeng Hospital Affiliated to Hubei University of Medicine from July 2016 to July 2018 were selected. Among them, RMPP was in 54 cases (RMPP group), and non-RMPP was in 93 cases (non-RMPP group). The white blood cell count (WBC), C- reactive protein (CRP), erythrocyte sedimentation rate (ESR), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatine kinase (CK) were detected; meanwhile, the serum levels of total LDH and LDH isoenzymes (LDH1, LDH2, LDH3, LDH4 and LDH5) were measured by radioimmunoassay. Results The ESR, AST, ALT, LDH1, LDH2, LDH4, LDH5 and total LDH in RMPP group were significantly higher than those in non-RMPP group:(23.15 ± 3.62) mm/h vs. (19.45 ± 3.04) mm/h, (37.20 ± 6.82) U/L vs. (31.49 ± 4.70) U/L, (35.48 ± 5.72) U/L vs. (27.31 ± 7.22) U/L, (89.77 ± 5.26) U/L vs. (85.01 ± 7.65) U/L, (154.60 ± 22.30) U/L vs. (133.17 ± 32.82) U/L, (61.51 ± 10.09) U/L vs. (47.74 ± 11.22) U/L, (78.99 ± 12.86) U/L vs. (64.98 ± 7.14) U/L and (511.49 ± 38.90) U/L vs. (450.19 ± 47.63) U/L, and there were statistical differences (P＜0.05); there were no statistical differences in WBC, CRP, CK and LDH3 between 2 groups (P＞0.05). Logistic regression analysis result showed that the ESR, AST, ALT, LDH1, LDH4 and LDH5 were the risk factors of RMPP ( OR=0.618, 0.735, 0.785, 0.769, 0.866, 0.880; 95% CI 0.430 to 0.888, 0.596 to 0.906, 0.665 to 0.926, 0.646 to 0.917, 0.781 to 0.961, 0.803 to 0.965; P<0.01). Receiver operating characteristic curve analysis result showed that the area under curve (AUC) of RMPP predicted by LDH5 was the largest (0.857), and then by LDH4 (0.819). The critical values were 70.74 and 53.14 U/L respectively; the AUC of RMPP predicted by LDH4 combined with LDH5 was 0.914, and the critical values was 130.10 U/L, with a sensitivity of 83.3% and a specificity of 92.5% , 95% CI 0.856 to 0.954. Conclusions Serum levels of LDH4 and LDH5 are significantly increased in children with RMPP. LDH4 combine with LDH5 detection might be useful in predicting the occurrence of RMPP.
ABSTRACT
investigate the diagnostic and predictable value of the levels of serum Trx (S-Trx), urinary Trx (U-Trx) and S-Trx/U-Trx ratio in acute pyelonephritis of children. Methods A total of 120 children with urinary tract infection were divided into APN group (67 cases) and non-APN group (53 cases).In addition , 67 children with APN were assigned to severe group (23 cases )and non-severe group (44 cases).
