[Show abstract][Hide abstract] ABSTRACT: The aim of our meta-analysis was to summarize quantitatively the association of genetic polymorphisms with cerebral palsy (CP).
We identified 16 studies on the association of genetic polymorphisms with CP in Pubmed, Elsevier Science Direct, Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure, and Wanfang. Eleven of these studies (involving a total of 2533 cases and 4432 controls) were used in the current meta-analysis. A study was included if (1) it was published up to September 2010 and (2) it was a case-control study. We excluded one study of family members because the analysis was based on linkage considerations. Meta odds ratios and 95% confidence intervals based on fixed-effects models or random-effects models were dependent on Cochran's Q statistic. We examined the relationship between alleles, as well as genotypes and susceptibility to CP.
Meta-analysis was performed for 17 genetic polymorphisms: apolipoprotein E (ε2,ε3,ε4), methylenetetrahydrofolate reductase (MTHFR) (rs1801133), coagulation factor II (rs1799963]), coagulation factor V (rs6025), coagulation factor VII (rs5742910/rs6046), interleukin-6 (IL-6) (rs1800795), endothelial nitric oxide (rs1800779/rs1799983/rs3918226), fibrinogen β-polypeptide (rs1800790), plasminogen activator inhibitor 1 (rs1799768/rs7242), TNF-β lymphotoxin α precursor (rs1041981), adducin 1 (α) (rs4961), ADRB2 (rs1042714), and tumour necrosis factor α (rs1800629). We found a significant association between CP and IL-6 (rs1800795) [C vs G: odds ratio (OR) 1.79, 95% confidence interval (CI) 1.44-2.22, p<0.001; CC+GC vs GG: OR 1.72, 95% CI 1.29-2.29, p=0.002; CC vs GG+GC: OR 2.17, 95% CI 1.52-3.09, p<0.001], but no other genetic polymorphisms.
This meta-analysis demonstrated that CP is associated with the genetic polymorphism IL-6 (rs1800795).

Rat models of Sprague-Dawley rats congenitally infected by HCMV were made. Field excitatory postsynaptic potentials (EPSPs) were recorded in the hippocampal slices of offspring rats (50-65days) to study alterations of LTP /DP in area dentate gyrus (DG) of the hippocampus after congenital infection. The Ca(2+) and mRNA level of calmodulin (CaM) in the hippocampus neurons of the experiment group (congenital infected by HCMV) and the control group were measured;The input/output (I/O) curves of the EPSP slope PS amplitude in area DG in experiment group were significantly depressed when compared to control group (P<0.05). LTP of the EPSP slope and PS amplitude in area DG of the hippocampus was 137±4% (EPSP) and 225±11% (PS) in control rats and 115±9% (EPSP) and 163±7% (PS) in experiment rats (EPSP: F=25.29,P<0.05;PS: F=74.33 P<0.05, two-way ANOVA with Tukey test); DP of the EPSP slope and PS amplitude was 86±3% (EPSP) and 85±2% (PS) in control rats and 94±5% (EPSP) and 93±4% (PS) in congenitally infected rats (EPSP: F=5.62, P<0.05;PS: F=4.22, P<0.05, two-way ANOVA with Tukey test) . At the same time, intracellular [Ca(2+)] and mRNA level of CaM in the hippocampus neurons of the experiment group were significantly increased than that of in the controls ([Ca(2+)]: P<0.01;CaM mRNA: P<0.01) . The results demonstrate that congenital HCMV infection could reduce the range of synaptic plasticity in the Sprague-Dawley rats, which may trigger the dysfunction of learning and memory through disrupting the calcium balance.

[Show abstract][Hide abstract] ABSTRACT: To study the efficacy of conductive education combined with Frenkel training in the improvement of balance function in children with cerebral palsy.
One hundred and fifteen children with cerebral palsy were randomly administered with conductive education and Frenkel training (study group, n=60) or conventional training (control group, n=55). Activities of daily living (ADL) scale and gross motor function measurement (GMFM) of physical performances were used to assess the balance function.
The scores of ADL scale and GMFM of physical performances in both the study and the control groups increased after training. The study group showed higher scores of ADL scale (37.91+/-10.12 vs 34.18+/-6.13; p<0.05)and GMFM (62.93+/-15.00 vs 54.53+/-14.11) than the control group (p<0.05).
Conductive education combined with Frenkel training is more effective for the improvement of balance function in children cerebral palsy.
