Objective To explore different aspects of empathy in patients with idiopathic generalized epilepsy and to study the effect of epileptiform discharges from different areas of the brain on empathy.Methods One hundred and fifty healthy controls and 62 patients with idiopathic generalized epilepsy were administered with a neuropsychological battery for basic cognitive assessment and an empathy scale after 24-hour electroencephalography monitoring.Results Compared with healthy controls,patients with epilepsy obtained significantly lower total scores and the cognitive empathy scores including perspectivetaking and fantasy subscale of the Interpersonal Reactivity Index-China (46.39 ± 9.74 vs 50.99 ± 9.97,t =-2.893,P=0.004; 23.31 ±7.10 vs 27.24 ±6.22,t =-3.974,P =0.000; 10.18 ±4.21 vs 11.84 ± 3.67,t =-2.838,P =0.005 ; 13.13 ± 4.46 vs 15.40 ± 3.84,t =-3.698,P =0.000,respectively).In contrast,the individuals with epilepsy did not score significantly different on the affective empathy,empathic concern and personal distress (P > 0.05,respectively).Patients with frontal epileptiform discharges suffered the most on the total empathy scores,cognitive empathy and perspective-taking subscale when compared with other three groups of individuals (P <0.05,respectively),whereas the groups did not differ from each other in affective empathy,empathic concern and personal distress (P >0.05,respectively).No correlation was found between the empathy ability and other cognitive neuropsychological tests.Conclusions Patients with idiopathic generalized epilepsy is not associated with a general empathy deficit,but rather with a dissociated pattern combining impaired cognitive empathy and preserved affective one,which leads to a double-dissociation,supports the notion that affective and cognitive empathies are two distinct abilities.The activation of epileptiform discharges from the frontal lobe is a key factor that could diminish the empathy ability.

With the development of data science, more and more attention has been paid to the non?invasive and quantitative method in precision radiotherapy all over the world. This paper will briefly introduce the concept of radiomics and its application in precision radiotherapy.

Objective To investigate the effects of acupuncture at bilateral ST36 (Zusanli) on attention networks in healthy subjects.Methods The attention network test was used to compare the effects of after acupuncture at ST36 with the effects of before acupuncture on the efficiency of three anatomically defined attention networks:alerting,orienting,and executive control in 40 health university students.Results The alerting network effect was significantly higher (t=4.125,P<0.001) after acupuncture ((45.60±3.49) ms) than before acupuncture ((33.20±2.88) ms).The executive control network efficiency was significantly higher (t=2.638,P<0.05) after acupuncture ((87.97±4.21) ms) than before acupuncture ((97.67±4.66) ms).The orienting network efficiency was higher after acupuncture than before acupuncture,but there was no significant difference (P>0.05).The average reaction time was significantly lower (t=4.848,P<0.001) after acupuncture ((559.13 ± 10.66) ms) than before acupuncture ((590.57±12.80) ms).Conclusions These results suggest that there are selective enhancements of the alerting and executive control networks after acupuncture,while the orienting network is spared.

Objective:To explore the relationship between spino-pelvic sagittal and coronal parameters in Lenke 1 group of adolescent idiopathic scoliosis (AIS).Methods:The subjects were retrospectively col-lected from 2005 to 2013.On the posteroanterior and lateral radiographs, apical vertebra ( AV) , Cobb an-gle of main thoracic curve (MT), pelvic incidence (PI), C7 translation ratio (C7TR) and other sagittal parameters were measured and recorded.Comparison and correlation studies were conducted between these parameters using specific softwares.Results: In the study, 51 subjects, including 18 males and 33 fe-males, were recruited, aged (14.9 ±2.0) years averagely.The apical vertebra ranged from T7 to T11,with mean MT being 49.6闭±16.7闭, and mean PI 44.7°±6.7°.Significant correlation existed between PI and PT, SS, LL, as well as between LL and SS, TK ( P <0.05) .Significant differences were found in TK, LL and SS among the different LM groups, but no difference in the other sagittal parameters.AV had no significant correlation with any sagittal parameter.MT was significantly correlated with TK, LL and SS, but its correlation with PI was not significant.Conclusion:Most of sagittal parameters were significantly corre-lated in Lenke 1 adolescent idiopathic scoliosis, forming a regulation chain of spine-pelvic sagittal balance on the basis of PI.Significant correlation exists between some sagittal and coronal parameters.

Objective To compare patient organ doses and entrance surface dose conversion coefficients in conventional radiography using medical internal radiation dose (MIRD) phantom and voxel human phantom.Methods The voxel phantom was adapted to the Monte Carlo transport code to simulate the organ doses and entrance surface dose in five common projections, and thus the dose conversion coefficients between the entrance skin dose and organ dose were calculated.The results were compared with the reported mean values which were simulated using MIRD phantom.Results The dose conversion coefficients values of organs covered or partially covered by the X-ray field ranged from 0.149-0.650 in chest postero-anterior projection, 0.067-0.382 in chest left lateral projection, 0.023-0.374 in chest right lateral projection, 0.035-0.431 in abdominal antero-posterior projection, 0.083-0.432 in lumbar spine antero-posterior projection.In chest postero-anterior projection, significant differences were most obviously observed in lung, the dose conversion coefficients difference was 54.3%.In chest left lateral projection, the dose conversion coefficients difference of liver was greatest, which was 54.5%.In chest right lateral projection, the dose conversion coefficients differences of stomach wall was most obviously 63.8%.In abdominal antero-posterior projection, dose conversion coefficients discrepancy was most obviously observed in spleen, with the value of 65.0%;while in lumbar spine antero-posterior projection, the dose conversion coefficients differences of stomach wall was most obviously 43.7%.Conclusions Compared with the stylized MIRD phantoms, the anatomical realism in voxel phantom is evident.Therefore, the dose conversion coefficients calculated by voxel phantoms are more accurate and scientific in conventional radiology.

AIM:To clarify the impact of heart shock factor 4b (Hsf4b) K65R mutation on the regulation of downstream protein expression .METHODS:Non-functional Lys mutant plasmid pWZL-blast-HA-Hsf4b/K65R was genera-ted by replacing single , homologous amino acids using KOD-Plus-Mutagenesis-Kit.Mouse lens epithelial mLEC stable cell lines expressing Hsf4b or Hsf4b/K65R were constructed by lentivirus infection .The expression of Hsf4b in the mutant and the wildtype mLEC cells was confirmed by Western blotting .The expression of Hsf4b downstream proteins such as heat shock protein ( Hsp)70, Hsp90, Hsp27 and CryAB was examined by Western blotting and real-time PCR.RESULTS:The results of PCR and DNA sequencing confirmed the successful construction of mLEC Hsf 4b/K65R mutant.The K65R mutation didn’t influence Hsf4b expression in the mLEC cells.After K65R mutation in Hsf4b, the expression levels of Hsp27 and CryAB were down-regulated and the expression of Hsp 70i and Hsp90a upregulated.CONCLUSION: pWZL-blast-HA-Hsf4b/K65R can be used to construct a stable cell line by infecting with lentivirus .Hsf4b/K65R mutation influ-ences the regulation of downstream heat shock proteins .
