OBJECTIVE:To systematically review the efficacy and safety of intrathecal injection of vancomycin combined with dexamethasone in the treatment of intracranial infection,and to provide evidence-based reference in the clinic. METHODS:Re-trieved from PubMed,Medline,CJFD,VIP,Wanfang databases,randomized controlled trials(RCTs)about intrathecal injection of vancomycin combined with dexamethasone in the treatment of intracranial infection were collected. Two reviewers independently screened literature,extracted data and assessed the risk of bias of included studies according to Cochrane system review manual 5.0.1. Then Meta-analysis was conducted by Rev Man 5.2 statistical software. RESULTS:Total of 8 RCTs were included,involv-ing 543 patients. Meta-analysis showed that,compared with intravenous dripping of ceftriaxone or vancomycin,intrathecal injec-tion of vancomycin combined with dexamethasone could significantly increase response rate [RR=1.18,95%CI(1.11,1.26),P<0.001] and bacterial clearance rate of CSF[RR=1.13,95%CI(1.01,1.27),P<0.001] of intracranial infection patients,shortened treatment time [SMD=-1.60,95%CI(-1.89,-1.30),P<0.001],reduce the incidence of ADR [RR=0.48,95%CI(0.32,0.73), P<0.001]. At the same time,it also could improve changes of intracranial pressure[SMD=-1.78,95% CI(-2.10,-1.47),P<0.001],changes of protein quantitation of CSF[SMD=-0.18,95%CI(-0.25,-0.11),P<0.001] and changes of glucose quantita-tion of CSF[SMD=1.77,95%CI(0.91,2.63),P<0.001],with statistical significance. CONCLUSIONS:Intrathecal injection of van-comycin combined with dexamethasone shows good clinical efficacy for intracranial infection,improves bacterial clearance rate, shortens treatment duration,significantly lowers intracranial pressure and protein quantitation,improves glucose quantitation of cere-brospinal fluid,with good safety.

Objective To investigate the effects of Thalidomide(THD)on transdifferentiation of human fetal lung fibroblast(HFL-F) to myofibroblast(MF) induced by Transforming Growth Factor-?1(TGF-?1) and the effects on trans differentiated MF.Methods HFL-F to MF trans-differentiation was induced with 5 ?g/L TGF-?1.The effect of 50 ?g/L THD on HFL-F to MF transdifferentiation was evaluated by measuring hydroxyproline(HYP) content with alkaline hydrolysis colorimetry,?-smooth muscle actin(?-SMA) protein with Western Blot,?-SMA and collagen Ⅲ(COL Ⅲ) mRNA with semiquantitative RT-PCR.Results THD inhibited TGF-?1 induced up-regulation of HYP and COLⅢ mRNA expressions(all P0.05).For HFL-F treated with 5 ?g/L TGF-?1 for 96 h,THD inhibited COLⅢ mRNA expression(P

Objective To investigate the potential roles of pattern recognition receptor in the pathogenesis of asthma,the concentrations of serum nucleotide -binding oligomerization domain like receptors 1 (NOD1 )and Toll like receptor 1(TLR1)and Dectin and sCD14 protein were determined.Methods Blood samples were obtained from 45 cases of severe asthma(asthma group)during acute attack and convalescent period,the concentrations of serum NOD1,TLR1,Dectin and sCD14 protein were assessed using enzyme linked immunosorbent assay(ELISA),and compared with 30 healthy children(control group).Results The concentrations of NOD1,TLR1,Dectin and sCD14 protein were significantly higher in acute attack period of the asthma group[(65.53 ±19.95)ng/mL,(10.46 ±3.35)ng/mL, (80.38 ±19.51)ng/mL,(4.51 ±1.29)ng/mL]than those in the control group[(25.57 ±9.64)ng/mL,(5.54 ± 1.49)ng/mL,(47.37 ±15.16)ng/mL,(2.21 ±0.68)ng/mL](t =11.57,8.63,7.82,9.95,all P <0.01).Moreo-ver,the concentrations of serum NOD1,Dectin and sCD14 protein were dramatically decreased in convalescent period of the asthma group[(39.67 ±11.25)ng/mL,(60.04 ±16.76)ng/mL,(3.38 ±0.97)ng/mL]compared with acute asthma attack period(t =8.19,6.32,5.42,all P <0.01),while the concentration of serum TLR1 was not different between this two period (9.51 ±3.19)ng/mL(t =1.27,P >0.05).Furthermore,level of NOD1 was positively corre-lated with sCD14(r =0.49,P <0.01).Conclusion Levels of serum NOD1,TLR1,Dectin and sCD14 protein were increased in acute severe asthma,whereas,they were decreased in convalescent period.The elevation of them indicated that pattern recognition reception has synergistic function in the pathogenesis of asthma attack.

Objective To analyze the clinical characteristics and treatment Methods of severe com?plications after percutaneous tracheotomy( PDT) in neurosurgery patients,and to provide reference for the treat?ment and rescue of these patients. Methods A retrospective analysis of 578 cases after PDT was performed in Neurosurgery Intensive Care Unit ( NSICU ) of Xuanwu Hospital of Capital Medical University from 2005 to 2015. The types of complications,treatment method and prognosis were analyzed. Follow?up was 3 months to 1 year. Results Eighteen cases with severe complications,including bleeding,wound infection,asphyxia caused by tracheal mucosa suffocation,airway stenosis caused by granulation tissue,subcutaneous emphysema and neu?momediastinum,etc. After treatment and active rescue,most patients recovered,no patients die directly associated with surgery. Conclusion PDT plays an important role in the treatment of patients in NSICU,but it is still pos?sible to have serious complications,so physicians must understand and be prepared for complications,and pay more attention to prevent poor prognosis.

ObjectiveTo discuss the values of fiber bronchoscopy with three-way laryngeal mask airway continuous ventilation in 1-6 month old infants with oxygen-dependent respiratory diseases.MethodsFrom January 2010 to May 2011, 29 cases of 1-6 month old infants with oxygen-dependent respiratory diseases who underwent conventional ifber bronchoscope and 148 cases of 1-6 month old infants with oxygen-dependent respiratory diseases who underwent ifber bronchoscopy with three-way laryngeal mask airway continuous ventilation were enrolled in control and treatment groups respectively. The success rate of ifber bronchoscope and the incidence rate of complications were compared between two groups.ResultsIn the treatment group, the success rate of ifber bronchoscope was 89.2% which was signiifcantly higher than 58.6% in the control group and the rate of laryngeal edema was 9.1% which was signiifcantly lower than 35.3% in the control group. The rates of endotracheal intu-bation ventilation and postoperative hemorrhage were lower than those in the control group, but the difference was not statistical ly signiifcant.ConclusionFiber bronchoscopy with three-way laryngeal mask airway continuous ventilation is superior to the traditional ifber bronchoscope in 1-6 month old infants with oxygen dependent respiratory system diseases.
