Objective To investigate the associations of a single-nucleotide polymorphisms (SNPs) in the interleukin (IL)-6 gene with the migraine of a Han Chinese northeastern population.Methods We collected 252 patients of the migraine attack,who were diagnosed at People' s Hospital of Liaoning Province from March 2012 to June 2013,all being Han nationality in the northeast of China.At the same time,we collected 270 healthy people over the same period who had health examination or were healthy workers of People' s Hospital of Liaoning Province.We used polymerase chain reaction and gene sequencing to analyze the genotype and allele frequencies of the-572G/C (rs1800796) IL-6 polymorphisms between migraine cases (n =252;including migraine without aura (MO) group (n =168) and migraine with aura group (n =84);the male group (n =109) and the female group (n =143)) and control group (n =270;the male group (n =116) and the female group (n =152)),as well as analyzed the genotype and allele frequencies distribution between the subgroups.Results We found higher frequencies of the distribution of the C/C genotype and the C allele of the-572G/C polymorphism in migraine cases than in control group (32.54％ (82/252) vs 19.63％ (53/270),x2 =12.061,P =0.002;55.56％ (280/504) vs 45.37％ (245/540),x2 =10.818,P =0.001),higher distribution frequencies of the C/C genotype and the C allele in female group (21.83％ (55/252) vs 12.59％ (34/270),x2 =10.187,P =0.006;33.73％ (170/504) vs 26.48％ (143/540),x2 =10.073,P =0.002).Between MO group and controls,these distribution frequencies had statistically significant difference (24.60％ (62/252) vs 19.63％ (53/270),x2 =18.172,P=0.000;39.88％ (201/504) vs 45.37％ (245/540),x2 =17.307,P=0.000).After correction by conditional Logistic regression,the frequency distribution difference of the C/C genotype between the migraine cases and controls remained statistically significant (OR =22.861,95％ CI 5.218-27.098,P =0.023).Conclusion Our data indicate that the SNPs of the IL-6 are associated with migaine and the C/C genotype increases the migraine susceptibility in a Han Chinese northeastern population.

Objective To investigate the value of high frequency magnetoencephalography signals in the localization of refractory temporal lobe epilepsy. Methods Retrospective analysis was performed in 10 patients with refractory temporal lobe epilepsy admitted to and accepted surgery in our hospital from January 2015 to December 2015. Surgical approaches of these patients were determined according to the results of long-term video EEG monitoring (VEEG), MR imaging, and conventional and high-frequency magnetoencephalography (MEG). MEG positioning analysis was performed after the surgery; followed up for 12 months was performed to evaluate the surgical efficacies. Results The surgery was effective in all the 10 patients; 5 patients achieved Engel grading Ⅰ, 2 patients achieved Engel grading Ⅱ, and 3 patients achieved Engel grading Ⅲ. The results of high-frequency MEG analysis indicated that 8 lesions were consistent with the surgical sites, enjoying good results; while the positioning error of the 2 patients was large. Conclusions The localization analysis of high-frequency neuromagnetic signals has the potential to determine epileptogenic zones preoperatively for epilepsy surgery. High-frequency oscillation is a new biomarker for the diagnosis of epilepsy.

Ossification of the spinal ligaments (OSL) is characterized by the appearance of pathologic bone tissue within the spinal ligamentous tissue. OSL tends to occur in the cervical and thoracic segments with important cause of spinal stenosis. Compression of the spinal cord or nerve roots by ossified masses can lead to severe neurological dysfunction, which has a tremendous impact on the quality of life of patients. However, the exact etiology and pathogenesis of OSL are still unclear. Epigenetic regulation is widespread in organisms and refers to the appearance of heritable changes in gene expression without alteration in genomic DNA sequence. As an important form of biodiversity regulation, epigenetic regulation plays an important role in development of several diseases. Epigenetic regulation has multiple manifestations in OSL, including DNA methylation, histone modifications, and non-coding RNA regulation. Sequencing tools, such as gene microarrays, have revealed significant differences in DNA methylation profiles and non-coding RNA expression between ossified and normal spinal ligaments. These differences can cause abnormal expression of osteogenesis-related target genes through direct or indirect pathways, thus affecting the ossification process of spinal ligaments. In addition, interactions between these epigenetic regulatory mechanisms constitute a large and complex regulatory network. Consequently, an in-depth understanding of the role of different epigenetic regulatory mechanisms and the linkages between them in the initiation and progression stages of OSL is expected to provide a valuable reference for the clinical diagnosis and treatment of OSL-related diseases.
