ABSTRACT
Objective To investigate the relationship between urine IgG of the first hospitalized children suffered allergic purpura and recurrence within one year. Methods Used immunoturbidimetry to determine acute-stage and convalescent urine IgG of 43 children suffered allergic purpura in the first hospitalized and no recurrence within one year (no recurrence group), and of 29 children suffered allergic purpura and recurrence within one year (recurrence group), and of 28 hospitalized children suffered primary nephrotic syndrome during the corresponding time period before hormonal therapy (nephrotie syndrome group), and of 30 children done medical examination in out-patient clinic (control group), then analyzed.Results There was no significant difference of the urine IgG level in acute-stage between no recurrence group [(1.391± 0.743) g/L] and recurrence group [(1.474 ±0.658) g/L](P>0.05), while they were all lower than that in recurrence group [(2.808 ± 0.683) g/L] (P < 0.01). The level of convalescent urine IgG in nephrotic syndrome group [(0.202 ± 0.154) g/L] was obviously higher than that in no recurrence group [(0.115 ±0.103) g/L] and control group [(0.109 ±0.098) g/L](P<0.05). Conclusion Urine IgG is a significant index to judge the activity and recurrence and prognosis of pedo-allergie purpura.
ABSTRACT
Objective To investigate the relationship between bronchoalveolar lavage fluid (BALF) levels of interleukin (IL)-6, IL-8 and child bacterial pneumonia. Methods BALF levels of IL-6, IL-8 were detected by enzyme linked immunosorbent assay (ELISA) in 26 patients with bacterial pneumonia and 14 controls. Neutrophils and alveolar macrophages (AMs) of BALF were examined. Results BALF levels of IL-6, IL-8, total cell count and neutrophils of child bacterial pneumonia before treatment were significantly higher than those of pneumonia after treatment and controls (P<0.01). BALF levels of IL-6, IL-8 were significantly higher in Gram-negative infection than those in Gram-positive infection (P<0.01). BALF level of IL-6 showed positive correlation with AMs in pneumonia (r=0.7615, P<0.01). BALF level of IL-8 was correlated positively with neutrophils and AMs respectively in pneumonia (r=0.8956, r=0.6018, P<0.01). Conclusions IL-6 and IL-8 play the roles in the development of airway inflammation in child bacterial pneumonia. Detection of BALF levels of IL-6 and IL-8 is valuable to predict the state of child bacterial pneumonia.
ABSTRACT
Objective To observe the clinical effect of gonadotropin releasing hormone analogues in treatment of the girls with idiopathic central precocious puberty(ICPP). Methods Twelve girls with ICPP received therapy with GnRH-A.Before and after the end of treatment for 6 months,secondary sexual characteristics and growth velocity were observed,pelvic ultrasonic examination,X-ray bone age(BA),serum level of E_2 and LHRH stimulating test were detected,and the predicted adult height(PAH) was analysed. Results After treatment,the size of breasts,uterus and ovaries were significantly reduced.The basic and peak levels of serum LH and FSH by LHRH stimulation were also significantly reduced.The ratio of BA/CA(chronology age)was decreased.The PAH was increased. Conclusions GnRH-A can effectively depress the sexual characteristics,reduce the maturation of BA,and also improve the PAH in girls with ICPP.
