Objective To evaluate the effects of early tracheotomy and delay tracheotomy on the prognosis of patients with severe craniocerebral injury.Methods Data of randomized controlled test (RCT) of early tracheotomy on the prognosis of the patients with severe craniocerebral injury were retrieved by using Conchrane Library,PubMed,Embase,OVID,CBM,CNKI,Wanfang and VIPdatahase.The retrievaled time was limited from their building to March 2016,and all the index of the obtained references was accessed.Two researchers independently screened the literature in accordance with the established criteria for inclusion or exclusion.The incidence of VAP,mechanical ventilation time and ICU length of hospital stay,mortality were considered as evaluation indexes.The methodology quality of the included references was evaluated,and the Meta-analysis was performed by using Review Manager 5.3 software.Results Finally,4 randomized controlled studies (RCT) were enrolled,including 220 patients.Meta-analysis results showed that:early tracheotomy did not have any effects on VAP incidence rate (P=0.15) and fatality rate (P=0.20) of the patients with severe craniocerebral injury,there was not any statistically difference;but there was a statistically difference between the mechanical ventilation (P =0.01) and ICU hospitalization time (P =0.05).Conclusion Early tracheostomy could not significantly reduce the incidence of VAP and fatality rate of the patients with severe craniocerebral injury,but it can reduce the mechanical ventilation time and ICU hospitalization time.

Objective To set up a new method,which is sensitive,low cost,rapid and suitable for clinical application for FTO gene rs9930506 variant genotyping basing on high resolution melting (HRM) platform,and to preliminarily put into practice in susceptibility analysis for metabolic syndrome (MS) in Beijing.Methods Unlabelled probe with C3-spacer block specific for rs9930506 variant has been designed according to the Refseq from GenBank.With LC-Green plus dye pre-mixed,we scanned the signal for the genotype analysis after PCR amplification and HRM reaction.Restriction fragment length polymorphism (RFLP) and PCR-sequencing methods were designed as 2 control genotyping methods for the evaluation of accuracy and convenience.Afterwards,the HRM-based method was put into practice in metabolic syndrome patients (n =500) and control groups (n =500) for rs9930506 genotyping,and primarily study the association between rs9930506 and MS.Results All the 3 methods could genotype rs9930506 appropriately,although the 2 control methods seemed to be a little time-inefficient.The call rate of HRM-method was 100％ and sampling accuracy reached 99.3％ according to sequencing results.In the MS group,AA,AG and GG genotypes were found in 290,185 and 25 cases,respectively.And in the control group,those were found in 344,138 and 18 cases.No genotype distribution difference was detected between control group and HapMap-CHB data (P =0.520 ).The genotype distributions were all in Hardy-Weinberg equilibrium in each group.AA genotype of rs9930506 seemed to reduce the risk for MS( OR =0.626,95％CI =0.483-0.812).Conclusions The AA genotype of rs9930506 variant in FTO might be a protective factor for MS in Beijing population.The susceptibility related genotyping in clinical samples could be more rapid,precise and inexpensive with the development of HRM in genotyping.

Objective To explore the clinical features,diagnosi s and prognosis of incontinentia pigmenti.Methods Analyzing and summarizing the clinical characteristic, diagnosis and prognosis of neonatal incontinentia pigmenti in 6 neonatal infants that were hospita- lized in our department during the period from January 1 998 to December 2003 were studied,and some relevant literature were reviewed. Results 1.Three of 6 infants were male which was unusual;2.Four infants had typical skin lesions at birth and 1 case at 6 days old.Four cases had typical 3 stages o f skin lesions including the erythematous and vesicular inflammatory stage,verr ucous lesions and hyperkeratosis stage,macular hyperpigmentation stage,but the re was overlap;3.Four infants were complicated by central nervous system involv ement (two cases presented mental retardation,2 infants were temporary damage). Two cases were complicated by ocular manifestations ( one case had optical nerve atrophy and blind in left eye,the other had severe bilateral retinal lesions); 4.On specific examination 5 infants were diagnosed by skin biopsy.Gene analysis was made in 1 case,but we didn′t find the mutations of NEMO. Conclusions Incontinentia pigmenti is a rare X-linked dominant multisystem disease.It may be misdiagnosed in the initial stages.Except typical clinical features,skin biops y and gene analysis are main evidence for diagnosis.Early detection and interven tion are important for prognosis.

Objective To improve the recognition of intramedullary spinal abscess by a case of congenital dermal sinus with intramedullary spinal abscess and reduco the incidence of congenital dermal sinus with intramedullary spinal abscess.Methods Clinical,laboratory data and image of a confirmed case about one infant of congenital dermal sinus with multiple intramedullary spinal abscess were investigated,the related literature was reviewed.Results In this case,when the infant with congential dermal sinus had infection,he failed to gain antibiotic therapy, timely surgical treatment,his infection had diffused, and multiple intramedullary spinal abscess flared up.Conclusions Intramedullary spinal abscess is a rare disease.If treatment is delayed, the prognosis is poor and the mortality rate is high.MRI is the ideal investigation for diagnosis.Intramedullary spinal abscess can happen subsequent to congenital dermal sinus with infection, and cause neurological sequela. So an infant with congenital dermal sinus should be offered to avoid complication caused by infection.

Objective:Establish mass-scale purification technology of cell-derived influenza virus. Methods: A microcarrier-based process was used to produce human influenza virus in serum free-adapted Vero cells. The virus was purified in a sequence of downstream processing steps including inactivation, clarification, anion exchange chromatography, affinity chromatography and size-exclusion chromatography. Results: The recovery of HA reached 102%. 95.3% total protein, including 99.77% host cell protein, and 99.99% host cell DNA were removed during downstream processing. Conclusion: Providing a high effective purification technology for cell-derived influenza virus.
