ABSTRACT
Objective To explore the significance of interleukin (IL)-1β and IL-6 in serum of children with hyperuricemia (HUA). Methods 142 children including 71 children with HUA (HUA group) and 71 control children (control group), healthy and inguinal hernia children were selected as control group. 71 HUA children were subdivided into GA (gout attacks) group (n=28) and NGA (non-gout attacks) group (n=43) according to whether they had a history of acute gout attacks, including sudden monoarthritis of rapid onset with intense pain and swelling or without. Enzyme-linked immunosorbent assay was used to measure the level of IL-1β and IL-6 in serum. Results Serum IL-1β and IL-6 levels of HUA children were significantly higher than those of control group (all P0.05). The serum IL-1β and IL-6 levels of HUA children were positively correlated with WBC, neutrophils, monocytes, uric acid, ESR, CRP, BUN and Cr (all P<0.05), while not correlated with triglyceride, total cholesterol, LDL-C and HDL-C(all P<0.05). Conclusion IL-1β and IL-6 play an important role in the pathogenesis of HUA in children.
ABSTRACT
Objective To observe the levels of N-terminal pro-brain natriuretic peptide (NT-proBNP),high density lipoprotein cholesterol (HDL-C) in predicting cardiovascular damage in Kawasaki disease (KD).Methods Enzyme-linked fluorescence analysis (ELFA) technique was used to measure serum NT-proBNP levels in 406 KD patients [including 104 cases of incomplete Kawasaki disease (IKD)] at the acute phase,the convalescent stage,at the same time,the blood HDL-C,Albumin,globulin,alanine aminotransferase (ALT),C-reactive protein (CRP),red blood cell sedimentation rate (ESR),blood white cell count (WBC),hemoglobin (Hb),blood platelet count (PLT) level were tested.According to the results of echocardiography,electrocardiogram,myocardial enzymes in KD,patients were divided into two groups:two hundred and twenty-two with cardiovascular damage and 184 without cardiovascular damage group.The age,gender,fever,the first application of the intravenous gamma globulin,laboratory markers of clinical features observed above the detection levels were compared,and these parameters for each group were compared using t test or analysis of variance,the single factor which was statistically significant were received operating characteristic curve (ROC) analysis.Then the cardiovascular damage group was divided into echocardiography abnormal group and echocardiography normal group,and t test was adopted to compare the clinical parameters of the two groups.Results ① The age,lip and oral changes,the first application of intravenous gamma globulin,blood NT-proBNP,HDL-C,albumn and ALT was significantly different between the cardiovascular damage group and non cardiovascular damage group (t/x22=4.989,4.721,6.212,18.834,12.788,4.851,4.541,All P＜0.05).② When the blood NT-pro-BNP was higher than 786.5 ng/L,its sensitivity and specificity for differentiating KD with cardiovascular damage was 86.5％ and 84.8％,respectively.When the blood HDL-C was lower than 0.655 mmol/L,its sensitivity and specificity for differentiating KD with cardiovascular damage was 80.4％ and 69.4％ respectively.When the blood NT-proBNP was higher than 786.5 ng/L in addition to HDL-C lower than 0.655 mmol/L,the specificity for differentiating KD with cardiovascular damage was 91.8％.③ For the 222 cases with cardiovascular dam-age,their blood NT-proBNP,HDL-C levels were statistically significantly different between the echocardiogra-phy abnormal group and echocardiography normal group (t=3.354,4.084,All P＜0.05).④ The serum NT-proBNP,ALT levels of the 406 acute and convalescent KD patients were significantly higher than the recovery phase.The blood HDL-C,albumin level of acute patients were significantly lower than those at the recovery phase,the difference was statistically significant (t=22.335,4.951,20.334,15.073,All P＜0.05).⑤ One hundred and four children with IKD were divided into patients with cardiovascular damage (74 cases) and without cardiovascu-lar damage (30 cases),the age,lip and oral changes,the first application of intravenous gamma globulin,blood NT-proBNP,HDL-C,albumin and ALT were significantly differentbetween these two groups (t=3.083,2.157,6.423,6.409,3.649,8.658,All P＜0.05).Conclusion Blood NT-proBNP and HDL-C are good pre-dictive parameters in children with cardiovascular damage of KD,IKD.
ABSTRACT
Objective To explore the correlation between the distribution of uric acid (UA) level and the biochemical indicators which reflect the degree of organ lesions among hospitalized children.Methods Patients who were hospitalized to the Department of Pediatrics and received the blood UA test from June 2012 to October 2013 were included,23 217 cases in total.The biochemical analyzer-Japan's Olympus AU 2700 was used to detect blood biochemistry; and uricase-peroxidase coupling method was used to detect blood UA.Among these patients,2 099 cases whose UA level exceeded the normal level.Then the patients' gender,age,primary diagnosis and UA level were recorded; and the distribution of their UA level was described.The Chi-square or Fisher test was used to assess the incidence rate.At the same time,each blood biochemical indicators of the patients with high UA level were recorded ; and the relationships between the blood UA of the 1 650 patients with complete records and each blood biochemical indicator were analyzed with Pearson correlation analysis.Results The incidence rate of hyperuricemia among the hospitalized children was 9.04％(2 099/23 217).In particular,the incidence rate among boys and girls was 6.5t％(890/13 657) and 12.65％ (1 209/9 560) respectively (x2 =256.9,P＜0.05).The incidence rate of hyperuricemiin different diseases was as follows:in the critical illness 36.93％ (113/306),neonatal disease 20.34％ (922/4 533),urinary system diseases 12.08％ (47/389),circulatory system diseases 11.67％ (21/180),nervous system diseases 11.05％(112/1 014),digestive diseases 10.50％(190/1 810),infectious diseases 10.18％(120/1 179),blood diseases 7.58％ (55/726),endocrine system diseases 5.74％ (17/296),autoimmune diseases 4.24％ (48/1 131),respiratory diseases 3.90％ (454/11 653) respectively (x2=1423.0,P＜0.05).The incidence of hyperuricemia at younger than one month was 18.31％(929/5 075),younger than one year old was 4.22％ (359/8 501),younger than six years old was 10.68％(600/5 618),younger than 15 years old was 5.24％ (211/4 023) respectively (x2=858.5,P＜0.05).Blood UA was positively correlated to urea nitrogen,creatinine,lacticdehydrogenase,α-hydroxy-butyrate dehydrogenase,creatine kinase and creatine kinase-MB (r=0.426,0.44,0.324,0.367,0.413,0.431,P＜0.05).Blood UA was not correlated to fructosamine,blood glucose,triglycerides,total cholesterol,low-density lipoprotein and high density lipoprotein.Conclusion The incidence of hyper-uricemia among hospitalized children is high; and the incidence among children with severe diseases and newborn babies is high; followed by in children with urinary system and circulatory system diseases.The blood UA level is closely related to the blood biochemical indicators which reflect the lesions of heart and kidney.
ABSTRACT
Objectives To explore the change of interleukin-17 (IL-17) in Kawasaki disease (KD). Methods Fourty KD pediatric patients, among them 12 patients with echocardiographic abnormalities in acute phase, 25 age-matched non-KD patients were enrolled. The level of serum IL-17 was measured by enzyme linked immunosorbent assay in acute and convalescent phase of KD patients and non-KD patients. At the same time, C-reactive protein (CRP), globulin, albumin were detected. Results In acute phase of KD patients, the level of serum IL-17 were signiifcantly higher than that in convalescent phase of KD patients and non-KD patients (P0.05). In acute phase of KD patients with echocardiography abnormalities, the level of serum IL-17 was signiifcantly higher than that with non-echocardiography abnormalities (P<0.05). The level of serum IL-17 in acute phase of KD patients were positively correlated with CRP and globulin (r=0.750, 0.750, P<0.05), and negatively correlated with albumin (r=-0.779, P<0.05). Conclusions IL-17 may be involved in KD immune pathogenesis. Serum IL-17 is one of the activity index of KD, which associ-ated with cardiovascular damages.
ABSTRACT
For observation on clinical therapeutic effect of modified Wei Er Fang on gastric precanceraus lesion (GPL), 90 cases of GPL were divided into 3 groups, the treatment group treated with modified Wei Er Fang, the control group I treated with Wei Fu Chuan and the control group I with Bismuth subcitrate, 30 cases each group. Results indicated that the total effective rate for clinical symptoms was 96. 67% in the treatment group which was significant different from 60. 00% in the control group I (P 0. 05), but the therapeutic effect on heterotypic proliferation in the treatment group was superior to those in the two control groups. It is showed that modified Wei Er Fang has a better action of reversing gastric precancerous lesion.
