Objective To explore the clinical and laboratory features,and gene diagnosis method of Menkes disease (MD).Methods The clinical and laboratory features and gene diagnosis method of 2 infants with MD were reviewed.Results (1) Clinical features:both infants mentioned in this article were male.Their clinical manifestations were both began at 3-4 months age,including peculiar kinky hair,pale skin,pudgy cheeks,inguinal hernia,vessel abnormality,epilepsy and mental retardation.(2) Laboratory features:the ceruloplasmin concentrations significantly reduced to be ＜ 20 mg/L and 47 mg/L,respectively.The magnetic resonance angiogram images of case 1 showed the abnormal tortuosity of his intracranial vessels.The magnetic resonance images of case 2 showed a rapid progress from normal to severe brain atrophy within half a year.(3) Gene diagnosis:the sequencing of ATP7A gene in case 1 showed a nonsense mutation of c.2110 C ＞ T.The pathogenicity of this mutation had not been reported previously at home and abroad.The sequencing of the gene panel without pathogenic mutation was detected in case 2.But the multiplex ligation-dependent probe amplification test showed a gross deletion of ATP7A gene containing 8-12 exons.This mutation had been documented as a pathogenic mutation of MD.Both mothers of 2 patients were heterozygous mutation carriers of normal phenotype.Conclusions MD is a multisystemic disease caused by ATP7A gene mutation resulting in copper metabolism disorder.MD is inherited as an X-linked recessive trait.MD is characterized by kinky hair,connective tissue abnormalities and progressive neurodegeneration.Clinical diagnosis can be made on the basis of clinical features,findings of blood biochemical examination,and radiological findings.Gene sequencing and multiplex ligation dependent probe amplification test are the main technique widely used for genetic diagnosis.

Objective To study the significance of the expressions of HIF-1? and E-cadherin in cervical carcinoma. Methods The expressions of HIF-1? and E-cadherin (E-cad) were determined in the clinical specimens of 109 cases of cervical carcinoma, 16 cases of cervical intraepithelial neoplasm and 10 cases of normal cervical tissue with immunohistochemical assay. Results There was nearly no expression of HIF-1? in the normal cervical tissue. The positive expression of HIF-1? and E-cad were 81.4% (70/86) and 28.6% (25/86) respectively in the tissue of invasive cervical carcinoma. The rate of positive expression of HIF-1? was significantly higher in invasive cervical carcinoma than in normal cervical tissue and cervical intraepithelial neoplasm (P

RESULTS By means of above mentioned measures and management,it could control in most degree of nosocomial infection in clinical laboratory,and ensure the safety and health of the department staff. CONCLUSIONS The nosocomial infection event of clinical laboratory can be prevented by amplification of necessary rules and regulation as well as enhancement of the management.

BACKGROUND: Pedicle screw fixation is mainly used to treat thoracolumbar disorders, and accurate placement is the key to success; thereafter, how to improve the accuracy of placement and reduce the secondary nailing is an issue of concern.OBJECTIVE: To compare the advantages and disadvantages of various pedicle screw placement methods and their application value.METHODS: CNKI and PubMed databases were retrieved for clinical research concerning the pedicle screw fixation for thoracolumbar disorders published before May 2016 using the keywords of pedicle screw fixation, free-hand technique,3D-printing technology, computer navigation technology, clinical application prospect in English and Chinese,respectively. The repetitive literatures were excluded, and the advanced pedicle screw technologies were collected and evaluated in views of feasibility, universality and practicability.RESULTS AND CONCLUSION: (1) Computer-assisted navigation system and three-dimensional printing technology are the focus of research, but only applied in the treatment of pedicle congenital malformations or complicated cases. (2) Free-hand technique is still the most widely used, which is the essential skills that surgeons must master. (3) Traditional technology is still the mainstream in clinic, so improved preoperative planning, and individualized scheme are needed.

Objectives To investigate the clinical significance of degree Ⅲ meconium-stained amniotic fluid in term pregnancy.Methods Data of 857 full-term gravidas underwent cesarean section for suspected fetal distress in Peking University First Hospital from October 1,2012 to September 30,2014 were retrospectively analyzed.All patients were divided into three groups according to the diagnosis of suspected fetal distress:meconium-stained amniotic fluid group (Group 1,n=172),fetal heart abnormality group (Group 2,n=623) and meconium-stained amniotic fluid in combination with fetal heart abnormality group (Group 3,n=62).General information and fetal prognosis of the three groups were analyzed.Factors that might affect the prognosis of newborns were analyzed between the infants with or without acidosis,asphyxia or aspiration pneumonia.Analysis of variance,independent-samples t test,Chi-square test and rank-sum test were used as statistical methods.Results There were no significant differences in maternal age,gestational age at delivery,parity,nuchal cord loop(s),pH value of umbilical arterial blood and gender of newborns among the three groups (all P＞0.05).The neonatal Apgar score,neonatal asphyxia rate and rate of admitting into pediatric ward within 24 hours after birth in Group 1 were similar to those of Group 2 and 3 [1 min Apgar score:9.9±0.7 vs 9.8±0.7 and 9.8±0.7,F=0.322;5 min Apgar score:10.0±0.3 vs 10.0±0.2 and 10.0±0.0,F=0.517;neonatal asphyxia rate:1.7％ (3/172) vs 2.1％ (13/623) and 1.6％ (1/62),x2=0.129;rate of admitting into pediatric ward:16.3％ (28/172) vs 14.3％ (89/623) and 11.3％ (7/62),x2-0.978] (all P＞0.05).The incidence of neonatal aspiration pneumonia in Group 1 was higher than that of Group 2 and 3 [4.7％ (8/172) vs 3.2％ (2/62) and 1.0％ (6/623)],but the differences had no statistical significance (F=10.680,P=0.050).Conclusions Both degree Ⅲ meconium-stained amniotic fluid and abnormal fetal heart rate have the same indicating significance and should be treated actively to lower the risk of poor prognosis of the newborns.

Objective To evaluate the contrast enhanced CT manifestations of lymphoma involving cervical lymph node and to compare with features of metastatic squamous cell carcinoma. Methods CT findings of cervical lymph node were reviewed in 56 patients (male 44, female 12; age: 9-75 year, median 42 year) with untreated lymphoma and 66 patients (male 51, female 15; age: 16-76 year, median 48 year) with squamous cell carcinoma. Four patterns of enhanced nodes were identified: Type I: homogeneous enhancement with an attenuation equal or similar to that of muscle. Type Ⅱ: heterogeneous enhancement with an attenuation much higher than that of muscle. Type Ⅲ: central low density with peripheral enhancement. The enhanced rim was thick and irregular (ⅢA), or thin and regular (ⅢB). Type Ⅳ: central soft tissue density with a very thin enhanced capsule. Results There were various manifestations of cervical nodes of malignant lymphoma, more than one type of abnormalities could be found simultaneously. Type I(47/56, 83.9%) and Type Ⅳ(15/56, 26 8%) were almost exclusively found in lymphoma. Type Ⅱ was more commonly seen in squamous cell carcinoma (31/66, 47%), but was rarely seen in lymphoma (8/56, 14 3%). Type Ⅲ can be seen in both of these disease entities (lymphoma 21/56, 37 5%; squamous cell carcinoma 52/66, 78 8%) , but was more common in squamous cell carcinoma ( P
