Objectives To study health-related quality of life(HRQOL) of children with subclinical epileptiform electroencephalographic discharges.Methods Subjects were 30 children with subclinical epileptiform electroencephalographic discharges,50 children with clinical seizures,28 children without clinical seizures and 30 controls.Guardians completed a valid epilepsy-specific HRQOL questionnaire for children,the quality of life in children epilepsy questionnaire(QOLCE).Results Children with subclinical epileptiform electroencephalographic discharges have 8 subscales scores lower than control group,2 subscales scores higher than group with clinical seizures.Conclusions Quality of life of children with subclinical epileptiform electroencephalographic discharges is better than that of children with clinical seizures.However cognitive,behavior,daily life and social activity are impaired by subclinical epileptiform electroencephalographic discharges and lowered the HRQOL of children.

Objective To study the effects of 50 Hz magnetic fields on the in vitro proliferation of human osteosareoma cell line MG-63 with different cell densities.Methods Four different magnetic intensities(1 mT, 2 mT,3 roT,4 mT)were used to stimulate the cells,and the experiment was repeated with different cell densities. The method of MTT was employed to evaluate the level of proliferation.Results Fifty Hz magnetic fields signifi- cantly affected the level of proliferation of human osteosareoma cell line MG-63,and the 2 mT intensity exerted the greatest influence on it.The effects of the magnetic field differed with different cell densities.Conclusion The effect of 50 Hz magnetic fields on the in vitro proliferation of human osteosarcoma cell line MG-63 was not only relat- ed to the magnetic intensity,but also the cell density,

Objective To screen for differential expression of genes in bone marrow mesenchymal stem ceils (MSCs) stimulated by electromagnetic fields (EMFs) and to study the mechanism of differentiation of the bone mar- row MSCs induced by EMFs.Methods Mouse bone marrow MSCs were isolated and cultured in vitro.The third- passage cells were stimulated by EMFs,then the total RNA was extracted,purified to cDNA and reversely transcribed to yield a cRNA probe.The cRNA probes from stimulated and control cells were labelled with Cy5 and Cy3,respec- tively.The two samples were hybridized with a mouse oligo microarray,and the hybridization signals were scanned. The reverse transcriptase polymerase chain reaction (RT-PCR) was used to identify the interesting genes:Duspl and Rabl.Results A total of 153 differentially expressed genes were found comparing the stimulated group and the control group.There were 74 up-regulated genes and 79 down-regulated genes in the stimulated group.Semi-quantita- tive RT-PCR confirmed that the Duspl and Rabl mRNA expression levels of the stimulated group were up-regulated. Conclusion The gene expression profiles of the bone marrow MSCs were altered after EMF exposure.The genes are involved in cell proliferation and differentiation,transcription control,metabolism and response to stress.These re- sults provide deeper insight into the mechanism of differentiation of the bone marrow MSCs.

OBJECTIVETo prepare the quercetin self-emulsified formulation and evaluate its quality.
METHODThe quercetin self-emulsified formulation was optimized based on the quercetin solubility in different oils, and the self-microemulsified efficiency of various combinations of emulsifier and co-emulsifier evaluated using the pseudo-ternary phase diagram. The microemulsion of morphology, size and zeta potential were examined. The quercetin of solubility in self-emulsified system was tested and the formulation stability was investigated by accelerated experiment.
RESULTThe blank self-emulsified system was composed of ethyl oleate/Cremophor EUL/butanol with weight ratio of 10: 54: 36. After being dilutied with water, the morphology of microemulsion was homogeneous small spherical drops observed under the electro-microscopy. The particle size and the zeta potential were 16.3 +/- 4.6 nm and 2.1 +/- 0.8 mV, respectively. The solubility of quercetin in self-emulsifing system was (62.42 +/- 0.11) mg x mL(-1), increased 2 229 folds compared with that of in water. The quality of quercetin self-emulsified formulation was stable during the 3 months storage at 40 degrees C.
CONCLUSIONThe solubility of quercetin is significantly increased in self-emulsified system and the formulation is stable and easy to prepare.

AIM:To point the susceptible gene in Avellino corneal dystrophy family with autosomal dominant inheritance.
●METHODS: Genomic DNA was extracted from the peripheral blood samples of all individuals of the pedigree. Several microsatellite makers were selected for gene scan in the hot regions of mutation. Linkage analysis was carried out using a Linkage software package. The haplotype data were processed using Cyrillic software to define the region of the disease gene.
●RESULTS: ln our pedigree, significant evidence of linkage was obtained at marker D5S396 and D5S393 [LOD score (Z)=3. 01, recombination fraction (θ)=0. 00]. The haplotype analysis of our pedigree was located between the microsatellite markers D5S808 and D5S638.
●CONCLUSION:The pathogenic gene of the Avellino corneal dystrophy pedigree is traced to a 11. 2 cM region in the chromosome 5q.

OBJECTIVETo study changes in the radiographic appearance during weight-bearing and non-weigh-bearing in hallux valgus, and to analyse the correlation between the elasticity of plantar soft tissue of hallux valgus and the pain under the metatarsal head.
METHODSFrom May 2012 to October 2012, 240 feet of 120 patients with hallux valgus were enrolled in the study. The degrees of the pian under the metatarsal head of all the patients were observed. AP and lateral X-ray films of feet were taken on the condition of weight-bearing and non-weight-bearing. So the hallux valgus angle (HVA), the inter-metatarsal angle between the first and second metatarsals (IM1-2), the inter-metatarsal angle between the first and fifth metatarsals (IM1-5), top angle of the medial longitudinal arch (TAOTMLA),and anterior angle of the medial longitudinal arch (AAOTMLA) were measured on the X-ray films. The differences of HVA, IM1-2, IM1-5, TAOTMLA and AAOTMLA between two groups were compared, and the correlation between the changes of IM1-2, IM 1-5, TAOTMLA, AAOTMLA and the degree of the pain under the metatarsal head were analysed.
RESULTSOne hundred and forty-eight feet had the pain under the metatarsal head. The IM1-2, IM1-5 and TAOTMLA increased on weight-bearing position compared with those on non-weight-bearing position, but the HVA and AAOTMLA decreased on weight-bearing position compared with those on non-weight-bearing position. There was a moderate relationship between the changes of IM 1-2,IM1-5 and the degree of the hallux valgus deformity, as well as the relationship between the different of IM1-5 and the degree of the pian under the metatarsal head.
CONCLUSIONThe degree of the collapse of the arch of foot with hallux valgus becomes serious with its deformity increasing. The pain under the metatarsal head of hallux valgus increases with the increased changes of IM 1-2,IM 1-5 and TAOTMLA. Analysis of the X-ray observation indexes of hallux valgus on weight-bearing position and non-weight-bearing position has important significance in evaluating the degree of the collapse of the arch of foot with hallux valgus,preventing and curing the the pain under the metatarsal head.
