Acute renal failure (ARF) is the common critical disease caused by various factors in neonates,its clinical manifestation is the sharp decline in renal function,in a short period of time,the serum creatinine is increased and urine volume decreases.However,recently,with the progress of blood purification technology,continuous renal replacement therapy (CRRT) has been used from ARF in elderly children to the newborn.In this paper,the risk factors of neonatal ARF,diagnostic criteria,the relevant questions of CRRT treatment were reviewed.

Objective To investigate the detection results of HBsAg,anti-HCV,anti-Treponema pallidum anti-body (anti-TP )and anti-HIV in patients before transfusion and surgery. Methods Four infection indicators of 28 165 patients were detected by enzyme-linked immunosorbent assay from June 2011 to May 2012,results were an-alyzed statistically.Results Of 28 165 patients,total positive rate was 12.15% (n= 3 422),the positive rate of HB-sAg,anti-HCV,anti-TP and anti-HIV was 8.69% (n= 2 447),1.31% (n= 368),2.07% (n= 583),and 0.09% (n=24)respectively. The positive rate of HBsAg,anti-HCV and anti-HIV in male was higher than female (χ2 was 36.64,28.95,and 4.82,respectively,allP<0.05).In different age groups,positive rate of all indicators in<20 age group was lowest,while positive rates of HBsAg,anti-HCV,and anti-HIV were highest in 20-39 and 40-59 age groups,anti-TP was highest in ≥60 age group.Conclusion Detection of bloodborne pathogens before transfusion and surgery is helpful for realizing infection status of patients before transfusion and surgery.

Acute kidney injury ( AKI) in newborns is one of neonatal critical disease,the incidence of AKI is 23%and the mortality is 25%~50%in neonatal intensive care unit (NICU).AKI in newborns is ab-normal renal function due to many various unfavorable factors,such as neonatal asphyxia,low blood volume, shock,hypoxia,hemolysis,low temperature,the clinical manifestations are oliguria or anuria,electrolyte disturb-ance,acid-base imbalance, high concentrations of metabolites in plasma and renal excretion ( urea, creatinine etc.) .At present,there are no effective prevention measures.In recent years,with the progress of blood purifica-tion technology,continuous blood purification ( CBP) has been used from AKI in children to AKI in newborns. Because of the neonatal hemodynamic instability and blood characteristics of small capacity, the application of CBP in the neonatal AKI still faces many problems.The paper summarizes high risk factors and diagnostic crite-ria of AKI in newborns,related problems of neonatal CBP treatment.

Irradiation induced tumorigenesis is a complicated process involving several phases such as initiating, promoting and progressing, just like the tumorigenesis induced by other factors. While irradiation induced tumorigenesis has its particularity on molecular mechanism, though the precise process remain unclear. Generally, irradiation can cause serious damage on DNA, which may bring irreversible consequences. For example, the double strand breaks (DSB) can induce the mismatch repair reaction, resulting in mutation of some specific genes or chromosomes in irradiated cells. The mutagenesis then make for the activation of oncogene, inactivation of tumor suppressor gene, uncontrolled cell proliferation and alterations of signal transduction pathway, all these work together to promote tumorigenesis. In addition, the gene instability, cytoplast mutation and cell group by stand effects induced by irradiation also play crucial roles in the process of tumorigenesis. [

To management of syncope in children and adolescents,the primary objectives are etiological diag-nosis and risk stratification.The possible causes for syncope ranging from relatively benign conditions to potentially life -threatening events.The efficient methods of diagnosis and risk stratification are vital important to identify those syncope patients who are at short -term or long -term risk of life -threatening events,avoiding unnecessary hospitali-zation of low -risk patients.In recent years,there came up with a multitude of quantitative methods in diagnosis and risk stratification,according to clinical history and physical exam and 1 2 -lead electrocardiograph.These methods can assit front -line physicians do an optimal decision -making,especially providing valuable guidance to make a well -in-formed choice between hospitalization and outpatient referral.Nevertheless,these existing methods can not replace criti-cal assessment by an experienced physician.

Hypoxic ischemic encephalopathy (HIE) is one of the leading causes of neonatal morbidity and mortality worldwide, and it has a series of clinical manifestations of encephalopathy.Survivors often have different degrees of neurodevelopmental impairment.In addition to supporting symptomatic treatment, hypothermia is the safest and most effective treatment for the neuroprotection and the improvement of the prognosis of neonatal HIE.However, hypothermia cannot provide complete neuroprotection and is limited by gestational age, time, and facilities and so on.Therefore, clinicians and researchers actively seek for supplements and/or alternative therapies for neonatal HIE.It was reported that stem cell transplantation has a good application prospect in the treatment of HIE.Erythropoietin and xenon and melatonin may also play neuroprotective roles in HIE.In order to provide a better theoretical basis for clinical practices, this paper reviewed the research progress of neonatal HIE treatment.

Objective To explore the effect and adverse reaction of topiramate(TPM) on treating Lennox-Gastaut syndrome(LGS)(including therapeutic alliance or single ). Methods Twenty-four cases with LGS whose attacks could not be controlled by re-(gular) therapy were selected.TPM was gradually increased from low dosage till its showing effect or untolerant adverse reaction.Results Two cases were excluded because of adverse reaction and increase of attacks. The remained cases were followed up from 6 months to 15 months (average: 9 months). The total effective rate was 82.6%, 11 cases accounting for 45.8% free of attack. The tonic-clonic seizure reduced more than 50% accounting for 82.2%, the full control accounting for 66.7%. The myoclonic seizure reduced more than 50% accounting for 81.8%,the full control accounting for 58.8%.The atypical absence seizure reduced more than 50% accounting for 81.8%, the full control accounting for 63.6%. The maximum effect occurred about 2-40 weeks following TPM used, the dosage about 2-10 mg/(kg?d).The adverse reaction included anorexia (8 cases), language disorder (5 cases), drowsiness (4 cases), decrease of anamnesis (3 cases), weight loss or unchanged(3 cases), inattention (3 cases), depression (3 cases), mental bradypraxia (2 cases ), skin damage (1 case), stupor (1 case), gross hematuria(1 case).The hepatic and renal function were normal during therapy. Conclusion TPM is a new, broad-spectrum, effective and safe antiepileptics drug on treating LGS.
