66 cases were treated with Yizhi(Intellingencebenefitted)Syrup. After treatment, the scores on behavioral appraisal markedly decreased with dramatic upgrading of learning results, marked lowering of positive soft nerve signs, the total effective rate being 84.8%. There wore also marked increase in the levels of urine NE, DA, 3-4(?)PAC, CAMP and(?)r.

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.

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 P<0.05). Serum IL-1β and IL-6 levels of HUA children in GA group were significantly higher than those of NGA group (P<0.05). Serum IL-1β and IL-6 levels of GA group in acute phase was significantly higher than those of HUA children in remission stage、NGA group and control group (P<0.05). Serum IL-1β and IL-6 levels of GA group in remission stage and NGA group was significantly higher than those of control group (P<0.05). There were no significant differences between HUA children in remission stage and NGA group (P>0.05). 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.
