OBJECTIVETo observe dystrophin and utrophin expression in muscle tissues of Duchenne muscular dystrophy (DMD) mouse model (dko mouse) after having been treated with bone marrow mesenchymal stem cells (MSC) transplantation.
METHODSThe fifth generation of MSCs, cultured in vitro, was transplanted into dko mice by tail vein. The fluorescent expression of dystrophin and utrophin in gastrocnemius muscle tissue of dko mouse was detected and the average optical density of positive fibers was calculated.
RESULTSMSCs that had been cultured for three generations had good homogeneousness and the immunological reaction after vein transplantation was low. There was an increasing tendency of dystrophin and utrophin fluorescent expression in sarcolemma of dko mouse within 5-20 weeks. Significant difference existed in fluorescent average optical density of positive fibers fifteen weeks before and after cell transplantation.
CONCLUSIONSMSC has strong plasticity both in vitro and in vivo. MSC has a trend to reach the injured muscle tissues and turn into muscle fibers, which express dystrophin and utrophin. There is some plerosis function for myatrophy of dko mouse by MSC transplantation.

OBJECTIVETo study the clinical efficiency, electroencephalogram (EEG) changes and cognitive improvements of ketogenic diet (KD) in children with refractory epilepsy.
METHODSTwenty pediatric patients (7-61 months in age) with refractory epilepsy were recruited between August 2012 and August 2013. KD therapy was performed on all participants for at least 3 months based on a fasting initiation protocol with the lipid-to-nonlipid ratio being gradually increased to 4 : 1. Seizure frequency, type and degree were recorded before and during KD therapy. A 24 hours video-electroencephalogram (V-EEG) examination and Gesell Developmental Scale assessment were performed prior to KD therapy, and 3, 6, 9 months after KD therapy.
RESULTSSix patients became seizure free after KD therapy, with a complete control rate of 30%. Seizure frequency reduction occurred in 13 (65%) patients, EEG improvement in 8 (40%) patients, and improvement in Gesell Developmental Scales (gross motor and adaptability in particular) in 6 (30%) patients. The KD therapy-related side effects were mild.
CONCLUSIONSKD therapy is safety and effective in reducing seizure frequency and improving EEG and cognitive function in children with refractory epilepsy.

Objective To investigate the prevalence and distributing feature of overweight and obesity in Han, Uygur and Hazakh population in adults from Xinjiang. Methods Four-stage selected random samples with maternal age at 35 or over were used to analyze the prevalence and distributing feature of self-reported congestive heart failure in different nationalities, age, sex. The sampled adult population were collected from 6 localities(Urumqi, Kelamayi, Fukang, the Turfan Basin locality, Hetian locality, Yili Hazakh autonomous prefecture), 23 municipalities and 7 locality and 5 autonomous counties in Xinjiang. Results 16 460 people were surveyed. The prevalence rates of overweight and obesity were 36.1% and 26.9% in Han, Uygur and Hazakh population in Xinjiang,respectively from February, 2007. The prevalence rates of overweight and obesity were 41.4% and18.4% in Han population, 34.9% and 28.9% in Uygur population, but 32.8% and 40.1% in Hazakh population. The prevalence rate of overweight and obesity was higher in males(x2= 135.00, P<0.05).The prevalence rates of overweight and obesity were different between different ethnic groups(x2=338.232, P<0.05). The prevalence of overweight was highest in Han population, with the highest seen in Hazakh population. The prevalence rates of overweight and obesity were increasing with age (x2=246.80,P<0.05). The overweight rate in 45-54 year olds and the obesity rate in 55-64 year olds reached their peak values. Results from logistic regression model analyses indicated that the prevalence of overweight and obesity in Xinjiang were statistically associated with age, educational level, jobs, smoking and alcohol consumption. Conclusion The prevalence rates of overweight and obesity were much higher in the population of Xinjiang but different among ethnicities. The prevalence of overweight was the highest in Han male population and the rate of obesity in Hazakh male population was the highest.
