ABSTRACT
Objective:To investigate the effect of high-frequency repetitive transcranial magnetic stimulation(rTMS)on cue attention in male patients with alcohol use disorder (AUD) after the acute withdrawal.Methods:A total of 90 male patients AUD who were hospitalized in the Second Affiliated Hospital of Kunming Medical University and Psychiatric Hospital of Yunnan province from May 2020 to December 2020 were enrolled, then they were divided into study group and control group using random number table.Because 18 cases fell out during the study, 36 cases were included in each of the two groups.After the alcohol withdrawal syndrome eliminated, the study group received high-frequency rTMS at 10 Hz for 14 consecutive days, and the control group was administrated by sham rTMS.At baseline and after true or sham rTMS, the cognitive psychology experiment Oddball paradigm was completed, and the behavioral data of the subjects were collected.Paired-sample t-test was used to compare the changes of the two groups before and after treatment.Data analysis were conducted using SPSS 21.0 software. Results:There was no statistical difference between the study group and the control group in terms of drinking level, cognition level and demographic data(all P>0.05). In the Oddball paradigm, compared with the control group((526.72±75.30)ms, (0.98±0.02))the reaction time((497.93±64.51)ms, t=3.145, P=0.008) and accuracy rate((0.99±0.01), t=-2.803, P=0.016) in alcohol-related cues were significantly improved in the study group after rTMS intervention, but in the control group, there were no statistical differences(both P>0.05), whether the cue was alcohol related or not. Conclusion:The results suggest that the rTMS can enhance the attention bias of alcohol-related cues and change the impulse process partly.
ABSTRACT
ObjectiveTo analyze the mental health status and the influencing factors among the residents taking standardized residency training during the outbreak and stable period of COVID-19， so as to provide theoretical basis for their mental health education. MethodsOn February 8 to February 10 and April 11 to April 13， 2020， Symptom Checklist 90 （SCL-90）， Beck Srivastava Stress Inventory （BSSI） and Simplified Coping Style Questionnaire （SCSQ） were distributed in online chat groups involving all grades of residents taking standardized residency training in the Second Affiliated Hospital of Kunming Medical University. Through two rounds of questionnaire survey， non-probability sampling method was used to obtain survey samples， and their mental status were analyzed. ResultsA total of 159 valid questionnaires were collected in the first round， and 99 valid questionnaires in the second round. The first survey showed that the total score of SCL-90 was （117.69±37.74） and the detection rate of positive symptoms in SCL-90 was 25.8%， and mainly dominated by obsession， fear and interpersonal sensitivity. In the second survey， the results showed that the total score of SCL-90 was （127.19±51.44）， and the main positive symptoms included obsession， depression and interpersonal sensitivity， with a positive detection rate of 30.3 %. The first survey found that the mental health status had significant differences among residents of different grades （χ2=7.46， P<0.05）， furthermore， the results indicated that lower grade was a risk factor while non-singleton was the protective factor of mental health status （P<0.05）， and SCL-90 total score was positively correlated with score of negative coping styles （r=0.45， P<0.01）. The second survey also classified lower grade as risk factor and non-singleton as protective factor （P<0.05）， and SCL-90 total score was positively correlated with study stress， economic pressure， interpersonal relationship， clinical practice and negative coping styles （r=0.52， 0.46， 0.55， 0.54， P<0.05 or 0.01）. ConclusionResidents under standardized residency training have obvious mental health problems during the outbreak of COVID-19， and the problems become more serious during the stable period of COVID-19.
