Objective To evaluate the value of early brain magnetic resonance imaging (MRI) in predicting future cerebral palsy in premature infants. Methods Searching the related literatures in PubMed,Embase,Cochrane,China Biological Medical Literature Database,China Academic Journal Full-Text Database,VIP Database and Wanfang Database.Inclusion criteria:(1) the purpose of the research was to evaluate the value of early brain MRI in predicting cerebral palsy of premature infants;(2) the type of research was prospective cohort study,randomized controlled trial,retrospective case analysis or case control studies; (3) the inspection was taken within 3 months of correction age; (4)the gold standard in diagnosing cerebral palsy was based on follow-up results,and the diagnosis criteria was clear.The sensitivity,specificity,positive and negative likelihood ratio were calculated and pooled by Stata11.0. Results Seven studies were enrolled into this meta-analysis including 772 premature infants and among which 92 were diagnosed as cerebral palsy.The pooled sensitivity was 0.93 (95％CI:0.65-0.99),specificity was 0.89 (95％CI:0.81-0.93),positive likelihood ratio was 8.19 (95％CI:4.48-14.94) and the negative likelihood ratio was 0.08 (95％CI:0.01-0.52),the area under the summary receiver operating characteristic curve was 0.95 (95％ CI:0.92-0.96).Significant heterogeneity was found (P＜0.05).When one retrospective study and one low morbidity study was removed,heterogeneity reduced significantly (P＞0.10),and predictive accuracy slightly decreased.The pooled sensitivity was 0.81 (95％CI:0.58-0.93 ),specificity was 0.82 (95％CI:0.76-0.87). Conclusions Early brain MRI has high accuracy in predicting future cerebral palsy of premature infant,especially for negative results.And for the premature infants with high risk factors,positive brain MRI result might have a higher predictive efficiency.

The purpose of this study is to obtain effective and stable bacteriocin-like substance from lactic acid bacteria. Lactobacillus buchneri KLDS1.0364,which was isolated from fermented cream,a traditional dairy product in Inner Mongolia,could produce bacteriocin-like substance. The bacteriocin-like substance produced by KLDS1.0364 was partially purified and the characteristics were studied. The bacteriocin-like substance was purified by SP-Sepharose fast flow cation exchange chromatography. The molecular weight of the bacteriocin-like substance was 21.6kD,as determined by tricine-SDS-PAGE. The bacteriocin-like substance remained stable after 30 min at 121℃ and after 2 h of incubation during pH 2～10. Complete inactivation of antimicrobial activity was observed after treatment of the bacteriocin-like substance with several proteinases. Treatment with catalase and ?-amylase did not result in any changes of antimicrobial activity. The mode of action of the bacteriocin-like substance is bactericidal. It exhibited a broad spectrum of antagonistic activity against various species of Gram-positive bacteria,Gram-negative bacteria and fungi.

AIM: To evaluate the effects and safety of intravitreal injection of triamcinolone acetonide ( TA ) or conbercept combined with macular laser grid photocoagulation in the treatment of macular edema secondary to retinal vein occlusion( RVO) . ·METHODS: Fifty cases ( 50 eyes ) with macular edema secondary to retinal vein occlusion were selected and assigned to 2 groups: intravitreal injection of TA or conbercept, and laser photocoagulation after 7d. Best corrected visual acuity ( BCVA ) , fundus examination, optical coherence tomography ( OCT ) and intraocular pressure ( IOP ) were examined before intravitreous injection and 14d, 1 and 3mo after laser, fundus fluorescein angiography(FFA) were examined 3mo after treatment. The postoperative results at each time point were compared with preoperative values. · RESULTS: Two kinds of treatment compared with preoperative, the BCVA all increased in various degrees. At 14d after intravitreous injection, 1 and 3mo after laser, the ratio of vision improved in TA group was 76%, 80%, 68%, conbercept group was 88%, 92%, 88%, BCVA of two groups in each period all had varying degrees of increase than preoperative. The best BCVA acquired at 1mo after treatment. The macular thickness after treatment was significantly lower than preoperative in two groups. At preoperative, 14d, 1 and 3mo after treatment, the macular thickness in TA group was 557. 5 ± 150. 9,301. 7±120. 1, 262. 7 ± 131. 2, 338. 1 ± 146. 5μm; the macular thickness in conbercept group was 569. 4 ± 135. 9, 282. 3 ± 133. 5, 259. 5 ± 116. 4, 307. 8 ± 122. 6μm. The macular thickness of the two groups were significantly different between preoperative and postoperative. · CONCLUSION: The combination of intravitreous injection of TA or conbercept with macular laser grid photocoagulation can be an effective method in the treatment of macular edema secondary to RVO, conbercept treatment is more effective and security.

Objective To explore the change of growth hormone binding protein (GHBP) in children with idiopathic short stature(ISS).Methods Thirty children with ISS from the pediatric department in the Third Hospital of Hebei Medical University and 30 age-and sex-matched normal-stature children were selected from Sep.2006 to Jun.2008.The concentration of GHBP was measured by enzyme linked immunosordent assay.Results Serum GHBP levels in ISS subjects was (3 261.0?646.3) ?g/L,while the serum GHBP levels in normal control group was (2 026.0?497.2) ?g/L,and there was statistically significant difference between both groups(t=-20.67 P

The gammac cytokines play an important role in proliferation and survival of T cells. Blocking the gammac signals can cause the activated donor-reactive T cells losing the ability to proliferate, and getting into apoptosis pathway, which contributes to induction of the peripheral tolerance. In this study, we induced the transplant tolerance through blocking the gammac in combination with donor-specific transfusion (DST) in the cardiac transplantation. Following DST, on the day 2, 4 and 6, C57BL/6 recipients received anti-gammac monoclonal antibodies (mAbs) injection, and those in control group were not given anti-gammac mAbs. On the day 7, Balb/c cardiac allografts were transplanted. All recipients in experimental group accepted cardiac allografts over 30 days, and two of them accepted allografts without rejection until sacrifice on the 120 day. Animals only receiving DST rejected grafts within 5 days, and the mice receiving cardiac transplantation alone rejected grafts within 9 days. Our study showed that blockade of gammac signaling combined with DST significantly prolonged allograft survival, which was probably associated with inhibition of antigen-specific T-cell proliferation and induction of apoptosis.

ObjectiveTo approach the status of leprosy disabilities in newly detected cases in recent 11 years in China.MethodsBased upon the records from the National Leprosy Recording and Reporting System in National Center for STD and Leprosy Control, 24128 leprosy cases detected during 1989-1999 in China were analyzed in terms of leprosy disbility.ResultsThe proportion of disabilies in newly detected leprosy cases in 1989 in whole country was 46.49% and decreased to 32.7% in 1999, and the proportions of cases with grade Ⅱ disabilities were 25.55% (1989) and 22.06% (1999). There were 19 provinces where disability rate was more than 40%. Out of patients with disabilities, those with grades Ⅰ and Ⅱ disabilities and with deformities (loss of eyebrow, facial paralysis or saddle nose) accounted for 37.54%, 61.04% and 1.42%, respectively. There were 20 provinces where grade Ⅱ disabilities accounted for more than 50% of all patients with disabilities. The disability rates in patients aged under 15 years, 15-65 years and over 65 years were 24.74%, 39.3% and 53.33%. The patients with a delay in detection of 2 years had a disability rate of 28.95%, and those with a delay of more than 2 years and 5 years had the rates of 48.06% and 60.95%, respectively. The disability rate was 53.76% in patients with leprosy reactions. The grade Ⅱ disability rate in paucibacillary patients (28.53%) was significantly higher than that in multibacillary ones (22.03%). Conclusions Disability rate of leprosy in newly detected cases is still high although it has decreased in the recent 11 years. The rate is associated with delay in detection, leprosy reaction and leprosy type. It suggests that early detection of leprosy patients, regular treatment with multidrug therapy, and management of leprosy reactions will be the effective measures to prevent disabilities of leprosy.
