Objective To study the relationship between blood lipid levels, insulin therapy of pregnant women with abnormal glucose metabolism and perinatal outcomes. Methods 380 pregnant women who were diag-nosed and treated for abnormal glucose metabolism were enrolled in this study,including 24 cases with diabetes melli-tus(DM),164 eases with gestation diabetes mellitus (GDM), 192 cases with gestation impaired 81ucose tolerance (GIGT). Among the 380 cases, 136 cases were performed insulin therapy with diet controlling,244 cases diet control-ling. Results The incidence of pre-eclampsia and preterm labor in the DM group(41.7% and 41.7% )was higher than that in GIGT group(15.6% and 20.7%)and GDM group(15.9% and 18. 3%) (P<0.05). Among the three groups ,the incidence of macrosomia, polyhydranmios and fetal distress had no significant difference( P>0.05 ). While the incipience of neonatal asphyxia,hypoglycemia in the DM group were all higher than that in GDM and GIGT group ( P<0.01 ). The newborn weights in insulin therapy group( 2891.5±1330.4 g) was lower than that in diet controlling group(3751.2±1025.3 g) ( P<0.05 ). Conclusion The blood lipid level of pregnant women with gestational ab-normal glucose metabolism is one of the effective indexes to prognose perinatal outcomes. Reducing blood lipid levelcan decrease the incidence of pre-eclampsia and preterm labor,neonatal asphyxia and hypoglycemia significantly. Di-agnosing and beginning therapy as soon as possible and using insulin are important,especially to reduce the rate of macrosomia and newbem weights.

Objective To investigate the prevalence,missed diagnosis rate and causes of acute kidney injury (AKI) in hospitalized children,and its impact on hospitalization cost,length of stay and outcome.Methods The data of children admitted in Children's Hospital Affiliated to Capital Institute of Pediatrics from December 1st to 31st 2014 were collected,and those whose serum creatinine (Scr) were measured at least two times were selected.Patients were diagnosed as AKI according to the diagnostic criteria of 2012 Kidney Disease:Improving Global Outcomes,then divided into AKI group and non-AKI group,the former of which was further divided into AKI1 group (Scr peak value in normal range) and AKI2 group (Scr peak value above normal range).The causes and impact of AKI on hospitalization cost,length of stay and outcome in different groups were compared and analyzed.Results (1) Among 921 patients with at least two Scr results,170 patients met with the diagnostic criteria of AKI,including 100 males and 70 females.There were 112(65.9％) in AKI stage 1,43(25.3％) in stage 2,and 15(8.8％) in stage 3.The overall prevalence of AKI was 18.5％.With only 7cases getting diagnosed,the diagnostic rate was 4.1％,while 95.9％ of patients missed diagnosis.(2)Among AKI patients,67 cases had pre-renal causes,103 cases had intra-renal causes and mixed factors.100(58.8％) cases got complete recovery,34(20.0％) cases recovered partially and 36(21.2％)cases did not improve,including 4 cases of death.(3) The prevalence of AKI among those below 1-year old was higher than children elder than 1-year (23.0％ vs 15.5％,P=0.004).The prevalence of AKI in surgical ward was higher than medical ward (30.7％ vs 15.8％,P ＜ 0.001).(4) Compared with those in non-AKI group,there was lower age [1.1(0.2,3.5) year vs 2.0(0.3,4.9) year] and higher hospitalization time[12.5(8.0,20.0) d vs 8.0(6.0,11.0) d],hospitalization costs [25 279.2(13 822.8,48 856.7) yuan vs 12 616.9(8680.1,19 345.1) yuan] and mortality (2.4％ vs 0.3％) in AKI group (all P ＜ 0.05).(5) There were 126 cases in AKL group and 44 cases in AKI2 group.The costs of hospitalization,outcome and mortality showed no difference between two groups (all P ＞ 0.05).The hospitalization time in AKI2 group was shorter than that in AKL group (P=0.038).Conclusions Among hospitalized children the missed diagnosis rate of AKI is high.Pre-renal factor is the main cause of AKI.Children younger than 1-year old are more susceptible to AKI.AKI children have lower age and higher hospitalization time,hospitalization costs and mortality than non-AKI children.The effect of Scr fluctuation within normal levels needs to be further studied.

Objective To retrospectively analyze the nutritional status and growth and development situation of the children with chronic kidney disease stage 3 to 5 when they were diagnosed at the first visit.Method After searching for the data of all the hospitalized cases during January 2007 to September 2015 in the Department of Nephrology of Children's Hospital Affiliated to the Capital Institute of Pediatrics from the medical record system,data of 37 cases with complete clinical data were collected;all these cases were diagnosed as chronic kidney disease stage 3 to 5 according to the diagnostic criteria.We recorded these children's age,height,weight,body mass index,albumin,blood lipids and acidosis situation when they were first diagnosed,and then,analyzed and summarized their nutritional status and growth and development situation.Result In these 37 cases,24 cases were boys and 13 cases were girls;23 cases (62％) were shorter than the third percentile of age-sex-specific height;18 cases (49％) exhibited lower weight than the third percentile of age-sex-specific weight;5 cases (13.5％) showed lower BMI than the third percentile of height-age BMI,and 5 cases (13.5％) had obesity.The level of albumin was (37.0 ± 8.7) g/L,and no statistically significant difference was observed within each stage.In all of these cases,10 cases were hypoalbuminemia (27％),and the difference of its frequency between stage 3-4 and stage 5 was not statistically significant.Triglyceride was (2.2 ± 1.1) mmol/L.The mean level was higher than the normal range,but with no statistically significant difference within each stage;21 cases (62％) were diagnosed as hypertriglyceridemia,which were more frequent compared with the occurrence of the hypercholesterolemia (32％),the high low density lipoprotein (26％) and the low high density lipoprotein(12％).And the occurrence of decompensated metabolic acidosis in stage 5 (69％) was significantly higher than that in stage 3-4 (38％) (P =0.036 6,＜ 0.05).Conclusion Growth retardation is highly prevalent among the children with chronic kidney disease stage 3 to 5.It would become more frequent and more serious as the stage worsening.Both underweight and obesity could be observed in this kind of children.Low serum albumin level is not a sensitive indicator of malnutrition in these children.The mean value of triglyceride in the children with chronic kidney disease was higher than the normal range.And hypertriglyceridemia is the most common abnormal lipid metabolism in our study.

Objective: To compare the efficacy and safety of mycophenolate mofetil versus cyclosporine A in treating children with primary refractory nephrotic syndrome. Methods: Conducted a prospective randomized controlled clinical trial in 62 pediatric patients (including 44 boys and 18 girls), age ranged from 2.1 to 17.0 years; 32 cases presented with frequently relapsing nephrotic syndrome (FRNS) and 30 cases presented with steroid-resistant nephrotic syndrome (SRNS), who were admitted to department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics from October 2013 to October 2015. The patients received either mycophenolate mofetil (20-30)mg/(kg·d) or cyclosporine A (3-5)mg/(kg·d) randomly, on the basis of prednisone treatment. Follow-up interview was conducted regularly for at least one year. Efficacy rate, relapse rate, time required for induction of remission, relapse-free period and prednisone dosage were compared between the two groups. Results: (1) Renal histologic examination, which was available for 17 patients, revealed minimal change disease in 8 patients, mesangial proliferative glomerulonephritis (MsPGN) in five, membranous nephropathy in two, and focal segmental glomerulosclerosis (FSGS) in two. (2) Comparison of mycophenolate mofetil versus cyclosporine A in children with FRNS: There were 14 patients with FRNS in mycophenolate mofetil group and 18 patients with FRNS in cyclosporine A group respectively. The relapse rate (episodes/year) in cyclosporine A group was lower than that of mycophenolate mofetil group (1.0 (0.0, 1.0) vs. 1.0 (1.0, 3.0), Z=-2.405, P=0.016). The relapse-free period (months) in cyclosporine A group was longer than that of mycophenolate mofetil group (10.0 (5.7, 12.1) vs. 5.0 (1.0, 11.0), Z=-1.984, P=0.047). No significant difference in dosage of prednisone was found between cyclosporine A and mycophenolate mofetil groups when followed up for 1 year. (3) Comparison of mycophenolate mofetil versus cyclosporine A in children with SRNS: The efficacy rate was 6/14 in mycophenolate mofetil group and 13/16 in cyclosporine A group. The complete remission rate was 4/14 in mycophenolate mofetil group and 12/16 in cyclosporine A group (P<0.05). The time (months) required for induction of remission in cyclosporine A group was significantly shorter than that of mycophenolate mofetil group (1.0 (1.0, 2.0) vs. 3.0 (2.5, 4.0), Z=-2.529, P=0.011). No significant differences were found between the two groups with respect to relapse-free period and relapse rate. (4) Except that one patient developed hypertensive encephalopathy in cyclosporine A group, no other serious adverse events were recorded. There were no significant differences between two groups with respect to adverse events. Conclusion Our results indicated that both mycophenolate mofetil and cyclosporine A were effective in the treatment of children with refractory nephrotic syndrome. Cyclosporine A was superior to mycophenolate mofetil in preventing relapses in patients with FRNS and inducing complete remission in patients with SRNS. Although most patients were able to tolerate mycophenolate mofetil and cyclosporine A, but the toxicity and safety of cyclosporine A should be monitored closely.
