Objective To study the clinical and genetic features of Lowe syndrome. Methods The clinical data and test results of OCRL gene from two children with Lowe syndrome were analyzed. The related literatures were reviewed. Re-sults Two male patients all presented with low molecular proteinuria, hypercalciuria, rickets and nephrolithiasis. Patient 2 had renal tubular acidosis, glycosuria and cryptochism. Patient 1 was found to have abnormal vision and congenital cataract soon after birth and treated surgically. Patient 1 also had psychomotor retardation and the cranial magnetic resonance ima-ging (MRI) showed agenesis of the corpus callosum. Patient 2 did not have obviously extra-renal symptoms, but was found to have mild cataract by a meticulous ophthalmological examination. MRI showed cerebral hypoplasia and myelination delay and mental retardation was gradually appeared during follow-up. Two OCRL gene mutations were detected. A splice site mutation NG_008638.1:g.46846-46848delTAA/insC was found in patient 1 and a frame shift mutation NM_000276.3:c.321delC in exon 5 was found in patient 2. Both mutations were not reported previously. Conclusions The diagnosis of Lowe syndrome is mainly by clinical manifestations and test of OCRL gene. Lowe syndrome needs to be included in the differential diagnosis of a patient with congenital cataract and renal tubulopathy. Two novel mutations in the OCRL gene were identiifed.

Full length cDNAs of Cucumber mosaic virus(CMV)CB7 strain,causing necrosis on Nicotiana glutinosa,were obtained by RT-PCR,using viral genomic RNAs as templates.cDNAs of CMV-CB7 genomic RNAs were cloned and sequenced and results indicated that RNA1,2 and 3 was 3 356 nt,3 045 nt and 2 218 nt,respectively(accordingly Accession Number EF216866,DQ785470 and EF216867).Infectious RNA transcripts from cDNA clones of CMV-CB7 were inoculated onto N.glutinosa and the seedlings of host plants displayed necrosis symptom,whist that of CMV-Fny induced typical mosaic symptoms.Through pseudorecombination between CMV-CB7 and CMV-Fny genomic RNAs,the genetic determinant of necrosis phenotype was mapped to RNA2.Chimeric infectious clones consisting of partial sequences of RNA2 derived from CMV-CB7 and CMV-Fny,respectively,were obtained by Overlapping PCR.Pathogenic analysis with those chimeric RNA2 revealed that 2b gene or 3' UTR of CMV-CB7 RNA2 was responsible for the necrotic pathotype.Northern blotting analysis reflected that both necrotic and non-necrotic viruses accumulated to similar levels of genomic RNAs in host plants.Therefore,necrotic phenotype induced on N.glutinosa was not related to the level of accumulation of CMV genomic RNAs.

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.
