Objective:To evaluate features and underlying pathogenesis of glucose metabolic disorder in pediatric patients with hyperthyroidism.Methods:The levels of blood glucose,insulin,c-peptide,glucagon,cortisol,T 3,T 4,TSH,TGA,TMA were measured in 29 patients with hyperthyroidism.20 normal age-matched children served as controls.In addition,fasting and post-prandial 60-minute erythrocyte insulin receptor of 14 children with hyperthyroidism and 7 normal age-matched controls were measured using insulin radioreceptor assay.Results:Incidence of glucose metabolic disorder was 34.5%.Incidence of glucose metabolic disorder in patients with more than one year course was higher compared with cases with less than one year course.In hyperthyroidism with glucose metabolic disorder,levels of glucose,insulin,insulin/glucose,insulin/glucagon at post-prandial 60 minute increased significantly.Numbers of fasting insulin receptor of high and low affinity in erythrocyte membrane were lower than post-prandial insulin receptor.Conclusion:Glucose metabolic disorder with impaired glucose tolerance and insulin resistance are present in patients with hyperthyroidism.The longer the course of the disease,the higher the incidence of glucose metabolic disorder.The decrease in the number of insulin receptor in target cells might play an important role in the mechanisms of glucose metabolic disorder and insulin resistance in children with hyperthyroidism.

Purpose To observe the ultrasonographic features of periventricular-intraventricular hemorrhage (PIVH) in preterm infants, to evaluate the value of cranial ultrasound for early diagnosis of PIVH. Materials and Methods 555 cases of premature children underwent bedside cranial ultrasound examination, characteristics of their ultrasound images were retrospectively analyzed and categorized with Papile grading, gradeⅢandⅣPIVH were defined as severe bleeding. Results 125 PIVH cases (22.52%) were detected by ultrasound, of which 111 cases (88.8%) were Papile gradeⅠ, manifested as hyperechoic group localized in the rear and below lateral ventricle anterior horn and in the sulcus of hypothalamic caudate nucleuscaudate;7 cases (5.6%) were Papile gradeⅡ, manifested as increased echogenicity, irregular widen or isolated mass shadow of the choroid plexus within the triangle zone and posterior horn of the lateral ventricle;7 cases (5.6%) were Papile gradeⅢ, manifested as hyperechoic group within the lateral ventricle with ventricular dilatation. 7 cases (1.26%) were severe PIVH. Overall incidence rates of PIVH in premature children whose gestational age was <32 weeks and ≥ 32 weeks were 45.05% and 16.89% respectively; overall incidence rates of PIVH for preterm infants whose birth weight were <1500 g and ≥ 1500 g were 44.16% and 19.04%, overall incidence of PIVH of preterm infants with gestational age<32 weeks and birth weight<1500 g was significantly higher than their contemporaries with gestational age≥32 weeks and birth weight ≥1500 g, and the differences were statistically significant (χ2=40.334, 23.978; P<0.01). Conclusion Incidence of PIVH becomes higher when the gestational age of preterm child is smaller and the birth weight is lower. Performing routine cranial ultrasound examination for preterm infants is important for early diagnosis of PIVH and Papile grading, thus will instruct the clinical intervention in early stage.

Objective To investigate the clinical value of serum procalcitonin(PCT),C-reactive protein(hs-CRP),white blood cell count(WBC)and neutrophil percentage(NEU％)in the early diagnosis of sepsis caused by different pathogenic bacteria infection to provide a risk assessment for sepsis patients.Methods The clinical data of 117 patients with sepsis caused by bloodstream infection in the intensive care unit(ICU)of our hospital from Oct.2013 to Oct.2015 were retrospectively analyzed.All patients were performed blood culture before antibiotics use and divided into the G+ bacteria group and G-bacteria group according to the results of blood culture.PCT,hs-CRP,WBC and NEU％ were detected in all cases.The differences in the detection results between the two groups were analyzed and the correlation between PCT with APACHE-Ⅱ and SOFA scores was evaluated.Results Among 117 cases of sepsis,78 cases were in the G+ bacteria group and 39 cases were in the G-bacteria group;compared with the G+ bacteria group,PCT in the G-bacteria group had obvious change and the difference was statistically significant(P＜0.05),while the detection results of hs-CRP,WBC and NEU in the G-group had little change(P>0.05);the serum PCT level was positively correlated with the SOFA score in the G-bacteria group(r=0.536,P＜0.05),but had no correlation with the APACHE-Ⅱ score(P>0.05);serum PCT level had no correlation with the APACHE-Ⅱ score and SOFA score in the G+ bacteria group(P>0.05).Conclusion PCT has some value in the early differential diagnosis and prognosis of sepsis caused by different pathogens,and it is more sensitive to G-bacteria.
