Objective To explore the attentional bias to emotional faces on individuals in the remitted phase of recurrent depression through eye-tracking study.Methods Center for epidemiologic studies depression scale (CES-D) and Hamilton depression scale (HAMD) were used to the diagnosis of 24 normal individuals and 21 depressed individuals and 24 individuals in the remitted phase of recurrent depression.Emotion face pictures were chosen as experiment material and discuss the mechanism of the attentional bias of individuals in the remitted phase of recurrent depression through the analysis of eye movement index.Results First fixation duration bias score on happy expression picture of individuals in the remitted phase of recurrent depression((52.60±0.06) ％) was less than normal controls ((59.26±0.09) ％) and the depression group((53.27±0.07)％),(F(1.66)=12.32,7.23,P＜0.05).Gaze Duration Bias score on sad expression picture of individuals in the remitted phase of recurrent depression ((59.17±0.08) ％) was more than normal controls((49.67±0.07) ％),(F(1.66) =4.29,P＜0.05).Conclusion Individuals in the remitted phase of recurrent depression show no original direction bias to sad and happy expression pictures.Original attentional avoidance and total attentional maintenance to sad expression picture exist in individuals in the remitted phase of recurrent depression.

Objective To observe the differences in event related potential(ERP) during sexual arousal elicited by different types of sexual picture in adult men.Methods An implicitly emotional task and a modified oddball paradigm were used.The differences were recorded in EEG with ERP when sexual arousal was induced by heterosexual couple erotic picture,male erotic picture and female erotic picture in fifteen health men.Results The amplitudes of N2 at Fz and P3 at Pz induced by male-female erotic picture ((2.32 ± 1.70) μV,(16.62 ± 2.16) μV),male erotic picture ((1.58 ± 1.33) μ V,(15.82 ± 1.64)μV) and female erotic picture ((1.23 ± 1.47)μV,(14.54 ± 2.00)μV)were not significant differences (P ＞ 0.05).But the amplitudes of N2 and P3 elicited by neutral human picture((-6.01 ± 1.35)μV,(11.36 ± 1.81) μV) were smaller than each type erotic picture (P ＜ 0.05).There was statistical significance in PSW at Cz elicited by different types of erotic picture.The PSW elicited by male-female erotic picture((12.59 ± 1.13)μV) was significantly higher than female erotic picture((10.38 ±0.76) μV) and male erotic picture((8.80 ±0.89) μV) (P＜0.05).However,there was no significant difference in PSW component between male erotic picture and female erotic picture.Conclusion The level of sexual arousal elicited by explicit heterosexual couple erotic pictures is highest and the attention also maintains longest in heterosexual male.

Objective: To study the effect of simulating scene method in teaching neurology.Method:Simulating scene method in teaching neurology of noviciate,the student and teacher joint evaluation and comparison with controlled group were applied.Results: According to students' evaluation,simulating scene method can improved students' leaning interest,clinical performing skill and clinical thinking,which had significant difference compared with that of controlled group.According to teachers'evaluation,simulating scene method could improve students'leaning attitude and elevate the clinical performing mark,which was also significantly different compared with controlled group.Conclusions:Simulating scene method can improved students' clinical performing skill and teaching effect.

Objective To investigate the role of activities of sympathetic nerve in the pathogenesis of shoulder-hand syndrome (SHS) by analyzing the hand sympathetic skin response (SSR) at the acute stage of SHS after stroke. Methods 50 stroke patients with SHS at the acute stage were assigned as SHS group, another 50 stroke patients without SHS as control group (N-SHS group) and 50 health volunteers as health group. Every patient was subjected to the detection of bilateral hand SSR. Results The detection rates of SSR in the SHS group and N-SHS group were significantly lower than that in the Health group (P<0.01). In comparison within the SHS group, the amplitude of SSR on the affected hand was apparently higher than on the healthy hand (P < 0.05), but there was no significant difference in the SSR latencies in both hands ( P > 0 . 05 ) . In comparison with the health group , bilateral SSR latencies of the SHS group were longer than those of the health group (P<0.05) and bilateral SSR amplitudes were all lower than those of the health group (P<0.01). Conclusions The bilateral hand sympathetic skin responses could change at the acute stage of SHS after stroke, with possible presentations of central inhibition of sympathetic activity. The abnormality of SSR may be an early warning indicator in patients with hemiplegia after stroke complicated with SHS.

Objective:To explore the characteristics of attentional bias to emotional faces of depressed college students with alexithymia.Methods:Using self-rating depression scale (SDS) and the twenty-item Toronto alexithymia scale(TAS-20), 25 low alexithymic-currently depressed undergraduates (LA-CD group), 33 low alexithymic-non depressed undergraduates(LA-ND group) and 23 high alexithymic-currently depressed undergraduates(HA-CD group) were selected from 885 valid questionnaires.Using eye tracking system, emotional face pictures were selected as stimulus materials, and the relative gaze time(attention bias score) of experimental participants was analyzed by statistical methods such as covariance analysis and adjustment analysis to explore the attentional bias of depressed college students with alexithymia.Results:(1) Under the low level of alexithymia, there was significant difference in attentional bias between college students in depression group (-0.23±0.18) and non-depressed group (0.06±0.11) ( F=55.876, P<0.01). (2) There were significant differences in relative attention bias among LA-CD group (-0.234±0.150), HA-CD group(-0.070±0.153) and LA-ND group (0.064±0.149) ( F(2, 78)=27.685, P<0.01). According to Bonferroni test, compared to the LA-CD group, the HA-CD group and LA-ND group showed less negative attentional bias.(3) The interaction between total SDS score and total TAS-20 score showed significant difference.Alexithymia played a regulatory role between total SDS score and attentional bias( β=0.333, t=3.345, P<0.01). Conclusion:Both the depressed college students with high alexithymia and the non-depressed college students with low alexithymia show less negative attentional bias.Alexithymia plays a regulatory role between depression and attentional bias.

A retrospective analysis was performed on one case of adult-onset type Ⅱcitrullinemia(CTLN2)caused by homozygous mutations of SLC25A13 genes.The patient,a 28-year-old male,had repeated limb convulsions for more than 4 years and worsened for 2 months.He usually liked to eat peanuts and meat.The brain MRI examination showed no abnormality,and anti-epileptic treatment was not effective.Further examination of blood aminotransferase,blood ammonia and citrulline were elevated,genetic testing showed that the SLC25A13 gene c.851_854del homozygous pathogenic mutation,the diagnosis was CTLN2,and the treatment was treated with a high-protein,high-fat,low-sugar diet and arginine,and there were no seizures followed up for half a year.Patients with recurrent seizures with special dietary preferences should be paid attention to the possibility of CTLN2,and genetic testing plays an important role in the diagnosis of CTLN2 and provides a basis for clinical diagnosis and treatment.

Objective:To explore the effect of rehabilitation nursing guided by precision nursing theory on the health belief and self-management behavior of patients with myocardial infarction after percutaneous coronary intervention (PCI) .Methods:Using the convenient sampling method, a total of 184 patients with myocardial infarction who received PCI treatment at Queshan County People's Hospital from January 2020 to January 2021 were selected as the research objects. According to the random number table method, they were divided into the observation group and the control group, with 92 cases in each group. The control group was given routine postoperative nursing, while the observation group was given rehabilitation nursing guided by precise nursing. Health Belief Scale and Self-management Scale were used to evaluate the effect of intervention.Results:Repeated measures analysis of variance showed that total scores of health beliefs and self-management behavior of patients in two groups existed time, the interaction effect between groups, time and between groups ( P<0.05) . Conclusions:Rehabilitation nursing guided by precision nursing theory can improve the health belief level and self-management behavior of patients with myocardial infarction after PCI.
