Chinese Journal of Immunology 2016;(2):251-255
Objective:To perform a meta-analysis of randomized controlled trials ( RCTs) in multiple sclerosis ( MS) patients to evaluate the efficacy and safety of alemtuzumab.Methods: We searched PubMed,EMBASE,the Cochrane Library and so on up to February 2015 using the keywords:′multiple sclerosis′or ′MS′and the drug names:alemtuzumab.Two authors independently selected the articles and extracted the data.We performed meta-analysis using Review Manager ( RevMan) version 5.3 software.Results:Three RCTs with a total of 1 695 patients were selected.Compared to the interferon beta,the number of gadolinium-enhancing lesions ( odds ratio (OR)=0.33,95% Confidence interval (CI)=[0.23,0.48],P<0.000 01),the cumulative probability of sustained disability (Or=0.51,95%CI=[0.38,0.69],P<0.000 1) and the proportion of patients who had at least one relapse of MS(Or=0.42,95%CI=[0.34,0.52],P<0.000 1) were significantly less in the alemtuzumab group,meanwhile the number of new T2-hyperintense lesions (Or=0.10,95%CI=[0.01,1.75],P=0.11) showed no significant difference.Comparing adverse events between two groups, alemtuzumab treatment did not increase the frequency of serious adverse events (Or=1.00,95% CI=[0.80,1.26],P=0.99) but increase the frequency of any adverse events (Or=2.29,95% CI=[1.40,3.75],P=0.001).Conclusion: Alemtuzumab is a relatively effective and safe treatment for MS.

Objective:To evaluate a Meta-analysis of randomized controlled trials ( RCTs) in multiple sclerosis ( MS) patients to evaluate the efficacy of vitamin D as add-on therapy. Methods: Searched Pubmed,EMbase,the Cochrane Library,CNKI,Wanfang Data base and so on up to february 2016 using the keywords:multiple sclerosis or MS and the drug names:vitamin D orCholecalciferol. Two authors independently selected the articles and extracted the data. We performed meta-analysis using Review Manager ( RevMan) version 5. 3 software. Results:Four RCTs with a total of 247 patients were selected.①Compared to the placebo, the EDSS score[MD=-0. 33,95% Confidence interval (CI)= (0. 68,0. 01),P=0. 05],the annual relapse rate[MD=-0. 08, 95%CI=(-0.37,0.21),P=0.60]and the number of gadolinium-enhancing lesions[MD=-0.16,95%CI=(-0.57,0.25),P=0. 45] showed no significant difference at 12 months,meanwhile the EDSS score[MD=-0. 48,95%CI=(0. 87,-0. 09),P=0. 02] and the annual relapse rate[MD=-0. 27,95%CI=(-0. 52,-0. 02),P=0. 03] were significantly less in the vitamin D group at 24 months.②Safety evaluation:There was no hypercalcaemia in vitamin D treated patients in each studies,main adverse events reported were diarrhoea, fever, constipation, dyspepsia, headache and so on. These symptoms were mild, after stopping drug can relieve the general. Conclusion: Vitamin D as an added in the treatment of MS showed as same as the placebo in some clinical indicators. However,after a longer treatment, the clinical indicators were significantly lower in the vitamin D group. Due to limited quantity and quality of the included studies,further larger and more prolonged studies are merited to verify the above conclusion.

ObjectiveTo explore the characteristics and correlation of intelligence development and socioemotional development in 1~3 years old children with expressive language disorder,and provide a basis for early intervention.Methods125 cases with expressive language disorder(language disorder group) and 126 normal children (normal group) are evaluated in two parts (intelligence and social mood) with 0~6 years old neuropsychological development diagnosis scale and Chinese version of urban infant-toddler social and emotional assessment.Results (1)The scores in language disorder group were lower than normal group in the area of free movements (81.60±10.40 vs 89.62±7.94),adaptability (81.48±10.95 vs 91.25±8.89),language (67.46±7.20 vs 89.13±8.24),social behavior (76.61±9.73 vs 90.12±8.13) and total developmental quotient (80.17±6.39 vs 91.15±6.05) (P<0.05).(2) There were significant differences between language disorder group and normal group in the area of externalizing behavior(56.28±10.15 vs 53.57±7.91),deregulation (56.45±10.61 vs 51.11±9.32) and capabilities(46.79±9.08 vs 51.25±7.47) (P<0.05).The boys' scores in internalizing behavior were lower than the girls' (49.19±10.76 vs 54.71±9.90) (P<0.05).(3) The scores of gross motor had positive correlation with externalizing behavior (r=0.220,P<0.05).The scores of language had negative correlation with externalizing behavior and deregulation(r=-0.650,P<0.05;r=-0.470,P<0.05).The scores of social behavior had negative correlation with externalizing behavior (r=-0.208,P<0.05).There was also a negative correlation between total development and deregulation (r=-0.184,P<0.05).(4) Multiple stepwise linear regression results showed that the externalizing behavior domain and mothers' education could predict 44.1% of variances in the language area.ConclusionThe children with expressive language disorder not only show backward in level of language development,but also in the development of other areas,and also bad social behavior and emotional problems.Individualized parenting interventions should be adopted to promote these children's intelligent development in an all-round way.

Objective To explore the effect of sequential and comprehensive preventative measures on the development of premature infants' intelligence.Methods A cohort of 120 premature infants was randomly divided into an observation group and a control group,each of 60.Both groups were given routine premature infant care,but the observation group was additionally provided with sequential and comprehensive preventive intervention.It included neonatal screening,inpatient-outpatient link-up,and their parents' watching CDs explaining early childhood education and health education.All of the infants were followed up from birth to 3 years old.Their adaptive capacity,fine motor skills,language acquisition,gross motor skills and social communication were evaluated at 12,24 and 36 months old using a child intelligence developmental scale for neurological development.Development intelligence quotients (DQs) were calculated and compared.Results After 12 months,significant inter-group differences were observed in adaptability and fine motor control.At 24 and 36 months old there were also significant differences in language skills.At one,two and 3 years old the average DQ of the observation group was significantly higher than that of the control group.Significant within-group differences in average DQ were observed in both groups between 1 and 2 years old,but not between 2 and 3.Conclusion Intervention within two years after birth is critical for premature infants.Timely,sequential,integrated,preventive intervention can promote the development of intelligence and better life quality for premature infants.
