Objective To evaluate the value of amplitude-integrated EEG(aEEG)as a quantitative predictor of neurodevelopment outcome of full-term infants with hypoxic-ischemic encephalopathy(HIE).Method EMBASE,Ovid,PubMed,Cochrane Library,Springer Database,CNKI,CSJD and Wanfang Database were searched from when the database was founded to June 30,2010 for studies about aEEG as a predictor of neurodevelopment outcome in full-term infants with HIE.Characteristic information of each articles was extracted and QUADAS items were used to evaluate the qualities of included studies.Meta-disc software 1.4 was used to perform the metaanalysis.All included studies were combined with weighted quantity; sensitivity,specificity,positive likelihood ratio,negative likelihood ratio and their 95 ％ CI were calculated.Results Eleven studies were eligible for the primary meta-analysis and totally 717 subjects were included.There was an overall sensitivity of 86％(95％ CI:81％-89％),specificity of 90％(95％ CI:86％-93％),positive likelihood ratio of 7.70(95％ CI:5.69-10.43),negative likelihood ratio of 0.17(95％ CI:0.13-0.22)and the area under the curve(AUC)of summary receiver operating characteristic curve was 0.95 for aEEG tracings to accurately predict poor outcome of HIE in full term neonates.Conclusion aEEG is a valuable bedside tool for predicting long-term neurodevelopment outcome in term infants with HIE.

Objective To explore the ideal choice of feeding artery which is used for regional arterial infusion (RAI) in severe acute pancreatitis. Methods Forty-five patients with SAP were treated with RAI. The ideal feeding artery was that can supply entire pancreas according to arteriography and can maximize concentration of drug at pancreatic tissue. The pancreatic arteriography was considered as the final objective evidence for choice. Results (1)Gastroduodenal artery was chosen as feeding artery in forty-four cases, and superior mesenterlc artery was chosen in only one case because of vascular abnormity. (2)According to splenic arteriography, blood of splenic artery was supplied to spleen chiefly, and only partial tail of pancreas was applied by splenic artery. (3)According to celiac trunk arteriography, blood of celiac trunk could be supplied to entire pancreas, but a considerable proportion of the total blood was supplied to spleen through splenic artery and liver through hepatic artery proper.Therefore, the drug utilization index was lower. (4)According to gastroduodenal arteriography, blood of gastroduodenal artery could be supplied to entire pancrea, and almost all of the blood that contains drug flowed into pancreas. Therefore, the drug utilization index was higher. Conclusions Gastroduodenal artery is the ideal choice of artery which is used for regional intra-arterial infusion in sever acute pancreatitis. Pancreatic arteriography should be applied routinely when yever acute pancreatitis was treated with RAI.

Objective:To investigate the clinical and genetic features of 3-methylglutaconic aciduria, dystonia-deafness, hepatopathy, encephalopathy, Leigh-like syndrome(MEGDHEL syndrome) caused by SERAC1 gene variation. Methods:This study retrospectively described the clinical and molecular features and prognosis of a baby boy who was transferred to Children's Hospital of Fudan University and later diagnosed with MEGDHEL syndrome in August 2016. A summary of the clinical and genetic manifestations of MEGDHEL syndrome cases reported in China and foreign areas was conducted through a literature review.Results:(1) Case report: The 2-day-old patient was transferred to Children's Hospital of Fudan University due to hyperlactic acidemia after birth. Physical examination revealed scattered petechiae and ecchymoses of the skin. Laboratory examination showed coagulation disorders and cranial MRI revealed abnormal signals in both basal ganglia. A homozygous variation of c.442C>T(p.Arg148*) in the SERAC1 gene was detected in the patient, which is a pathogenic variant included in the Human Gene Mutation Database. Both of his parents were heterozygous carriers, thereby the diagnosis of MEGDHEL syndrome was confirmed. Followed up to the age of three years and 11 months, he was found to have psychomotor retardation, spasticity, dystonia, deafness, and loss of language ability. (2)Literature review: Together with the case reported in this study, a total of 88 cases were retrieved, involving 57 different variants. The clinical features were homogenous, with onset mostly in the neonatal period (72%, 62/86), and severe reversible liver dysfunction (49%, 38/77) and neonatal hypoglycemia (44%, 35/80) were the main features. Nervous system was affected since infancy and common symptoms, included hypotonia (86%, 68/79), progressive spasticity (82%, 67/82), dystonia (80%, 66/82), intellectual disability (88%, 58/66) and sensorineural hearing impairment (74%, 59/80). Furthermore, bilateral basal ganglia involvement on cranial MRI (93%,70/75) and 3-methylglutaconic aciduria (98%,80/82) were also seen. Supportive care is currently the main management, however, the prognosis is extremely poor. Conclusions:MEGDHEL syndrome should be highly suspected when reversible neonatal liver dysfunction or hypoglycemia of unknown reasons in neonatal period, followed by progressive deafness-dystonia syndrome in infancy. As the prognosis of these patients is usually poor, genetic testing may provide an early diagnosis in neonatal period.

Objective To screen for genomic copy number variants(CNVs)in six neonates with Pierre Robin sequence(PRS)by Affymetrix 2.7 M chip to identify possible loci related to PRS.Methods Six neonates with PRS admitted into the Department of Neonatology,Children's Hospital of Fudan University from June 2009 to May 2010 were enrolled in this study.CNVs were detected by Cytogenetic Whole Genome 2.7 M array.Rare CNVs with potential clinical significance that deletion segments' size ＞50 kb and duplication segments' size ＞200 kb were selected based on the analysis of Chromosome Analysis Suite(ChAS)software,false positive CNVs and segments of normal population were excluded.The identified CNVs were compared with those in relative published literatures.Results(1)Among 6 PRS patients,two patients had facial deformation,two had congenital heart defects,one had congenital dysplasia of the laryngeal cartilage and one had choroidal space occupying lesion.(2)Seven rare CNVs whose size from 51-11 956 kb were identified in four neonates,including a 739 kb duplication on lp26.23-p36.22,a 6273 kb deletion on lq43-44,a 51 kb and a 55 kb deletions on 14q32.31,a 1022 kb duplication on 14q11.1-11.2,a 11 956 kb duplication on 20p13 and a 105 kb deletion on 4q23.3.(3)Published literatures showed that deletions of 1q43-44 and 14q32.31 might relate to micro/retrognathia and abnormal palate.Region of chromosome 1q43-q44 contained AKT3 and heterogeneous nuclear ribonucleoprotein U(hnRNPU)genes,and the haploinsufficiency of AKT3 and hnRNPU genes might cause developmental human microcephaly and agenesis of the corpus callosum,speech delay and seizures respectively.Region of chromosome 14q32.31 contained some C/D small nucleolar RNA,and the human imprinted 14q32 domain shared common genomic features with the imprinted 15q11-q13 loci.Conclusions This study established a method to discover whole genome CNVs in identifying novel submicroscopic deletions and duplications.Reviewing of published literatures suggested that deletions of chromosome 1q43-q44 and 14q32.31 might cause Pierre Robin sequence.

Objective To discuss the safety and effectiveness of transurethral resection of the prostate (TURP) on large-size (≥ 80 ml) benign prostatic hyperplasia (BPH).Methods Retrospective analysis of 958 BPH patients in Southwest Hospital during January 2010 to January 2013 was conducted.The patients were grouped into ≥80 ml prostate group (Group A) and ＜80 ml prostate group (Group B) according to the volume of prostate.Comparison was made between the 2 groups on the safety and effectiveness of TURP.Results There were 276 patients in Group A and 682 in Group B.No significant differences were shown in average age and preoperative American society of anesthesiology score of Group A and B.Compared with Group B,decrement in hemoglobin level and blood Na+ concentration of Group A was more significant (P＜0.01).There were more prostate tissues excised and duration of the operations was longer (P＜0.01).No significant difference was observed in peri-operative complications graded by the modified Clavien classification system,catheter durations and durations of hospital stay between the 2 groups (P＞0.05).At 6 months after the surgery,average maximum urinary flow rate (Qmax) increased from 5.9±2.9 ml/s to 17.1±8.2 ml/s for Group A and 6.1±3.0 ml/s to 17.5±6.4 ml/s for Group B,both groups showed significant increase in Qmax after surgery(P＜0.01).Six months after surgery,international prostate symptom score (IPSS) of Group A decreased from 23.7±6.1 to 5.9±4.9 while IPSS of Group B decreased from 23.1±5.5 to 6.2±4.4,both groups showed a significant decrease (P＜0.01).No significant difference was shown in IPSS,quality of life,Qmax,postvoid residual urine volume and occurrence rate of long-term complications after 6 months between the 2 groups (P＞0.05).Conclusion TURP is as safe and effective in treating large-size BPH as treating medium and small-size BPH.

BACKGROUND:In clinical application, the structure of crista lambdoidalis of L5 was unclear. It needs to expose more tissue to define L5 entry point through transverse process or superior and inferior articular process. This increased the risk of trauma and iatrogenic superior intervertebral degeneration. Therefore, it is necessary to expose L5 entry point with a minimaly invasive way. OBJECTIVE:To investigate the accuracy of L5 pedicle screw insertion with the entry point of mastoid process slope by imaging. METHODS:Mastoid process was located on the base of L5 superior articular process. A cant was formed when the highest point of L5 mastoid process backward protuberance extended inwards and downwards. The cant was defined as mastoid process slope; it was lateral to pedicle medial superior side internaly, medial to transverse process root and superior to the top of crista lambdoidalis. The slope was first easily touched and exposed in lumbar posterior surgery through paraspinal muscle space approach. Fifty patients of lumbar spine disorders were treated by L5 pedicle screws fixation through the entry point of mastoid process slope. According to preoperative radiographic and CT images, pedicle screw insertion direction of the sagittal and transverse sections was calculated. The diameter of pedicle screw was 6.5 mm. The condition of intraoperative successful rate of screws placement at one time was analyzed. The accuracy of screw placement was evaluated by postoperative radiographic and CT images. RESULTS AND CONCLUSION:With the method of the mastoid process slope, the successful rate of screw placement at one time was 96% (96/100). Totaly 100 screws were inserted into L5. According to the criterion by Gertzbein, 95 screws (95%) totaly located in pedicles and 5 screws (5%) encroached on the pedicle from medial wal. Three (3%) out of 5 inaccurately placed screws cut out less than 2 mm of the inner wal, while 2 (2%) between 2 mm and 4 mm, without neurologic deficits. The method of mastoid process slope had a high successful rate of screw placement. Combined with preoperative X-ray films and CT images could obtain a high accuracy rate of screw insertion.
