RESUMEN
Objective@#To investigate the expression levels of serum neuron specific enolase (NSE), interleukin-1β (IL-1β)and brain derived neurotrophic factor(BDNF) in adolescents with generalized anxiety disorder(GAD), so as to provide reference for the early diagnosis and evaluation of GAD in adolescents.@*Methods@#From March 2020 to February 2023, 97 first episode adolescents with generalized anxiety disorder aged 13-18 years were selected in the study. According to the score of generalized anxiety disorder questionnaire (GAD-7) on admission, they were divided into mild moderate GAD group (58 cases) and severe GAD group (39 cases). At the same time, 90 healthy adolescents who participated in routine physical examination in the same period were selected as the control group. Variance analysis was conducted for comparison among serum NSE, IL-1β and BDNF level. LSD t was applied for further comparison, and the bivariate Pearson linear correlation analysis was carried out for the relationship among serum NSE, IL-1β and BDNF level.@*Results@#The differences among 3 groups of subjects on NSE and IL-1β, and BDNF were of statistical significance( F =10.73, 12.80, 20.67, P <0.01), and the differences between groups were statistically significant ( P <0.05). In the control group, serum NSE level was(8.70±1.35) μg/L, IL-1β was (18.42±5.43) pg/mL, both were the lowest. The levels of NSE and IL-1β in severe GAD group were(14.21±3.25) μg/L, (26.04±5.39)pg/mL, which were the highest. The serum BDNF level in control group was (27.16±4.42) ng/mL, which was the highest; and the severe GAD group was (10.46±3.27) ng/mL, which was the lowest. The bivariate Pearson linear correlation analysis showed that the serum NSE and IL-1β levels in GAD group were negatively correlated with the serum BDNF level ( r =-0.49, -0.57); the serum NSE level was positively correlated with the IL-1β level ( r =0.40) ( P <0.05).@*Conclusions@#The serum levels of NSE and IL-1β are abnormally increased in adolescents with GAD, and the serum levels of BDNF are significantly decreased. The serum levels of NSE, IL-1β and BDNF can be used as detection markers for adolescent GAD, which is helpful for early diagnosis and disease evaluation.
RESUMEN
Objective@#To investigate the change in intestinal flora in Mongolian students with anxiety,so as to provide basis for exploring the relationship between flora and secretion expression in vivo.@*Methods@#The Self rating Anxiety Scale(SAS)was used to assess anxiety in medical college students; then a semi structured interview was administered. Fecal samples that met the inclusion criteria were collected and divided into anxiety (SAS score≥50) and control groups (no anxiety, SAS score<50) according to the standard score of SAS. Samples provided by Mongolian female students were selected from each group. The total bacterial DNA was extracted from the fecal samples for PCR amplification and NovaSeq 2x250bp high throughput sequencing was performed for the V3- V4 region of 16S rDNA gene to obtain the biological information of the intestinal flora. The intergroup OTU, structural diversity, significant difference, and LEfSe analyses were performed with information mining of the literature think tanks.@*Results@#Anxiety existed in 23.86% of the Mongolian students,and 16.96% of the Han people. A Chi square test showed no significant difference in detection of anxiety between Mongolian and Han college students ( P =0.07). Analysis of the alpha diversity index showed that the Shannon index, Simpson index, Chao1 index, and Observed species did not differed significantly between the two groups( t =8.0， 9.0 ，6.0，6.5). The difference in abundance of some bacteria was significant at the Class, Order, Family, and Genus levels between the two groups( t =-2.26-2.57，-5.08-3.58，-2.65-2.09， P <0.05).@*Conclusion@#The alpha diversity index showed that there was no significant difference in the abundance and diversity of intestinal flora between the two groups. While there were significant differences at different classification levels, the results suggest that the structure of intestinal flora can change in students with anxiety.
RESUMEN
Objective@#To explore health self-management, adaptation, and perceived stress among nursing interns in medical colleges and universities under the normal prevention and control of COVID-19, and to provide a scientific basis for the health management of practice nursing students.@*Methods@#Medical colleges in the Inner Mongolia region were selected to study 263 nursing student interns by cluster random sampling. The survey was conducted using the Health Self-Management Ability Assessment Scale, the Chinese College Students Adjustment Scale and the Perceived Stress Scale.@*Results@#The total score of health self-management ability of nursing students during internship was (138.31±20.13). The total score of health self-management ability of nursing students with different educational backgrounds and different residence places was statistically significant ( F/t =3.51, 2.46, P < 0.05 ); the total adaptive score was (3.17±0.72); during the epidemic, the total score of perceived stress was (11.52±2.79), and the difference in the total score of perceived stress among nursing students with different educational backgrounds was statistically significant ( t=4.05, P <0.05). Pearson analysis showed that there was a significant negative correlation between health self-management ability, adaptation, and perceived stress among nursing students during the epidemic period ( r =-0.31, -0.35, P <0.01).@*Conclusion@#There was a close relationship between perceived stress of nursing students and health self-management and adaptation; the educators in medical colleges should actively explore strategies to improve the health self-management ability and adaptation level of nursing students to enhance the psychological adjustment ability of nursing students to maintain good physical and mental health.
RESUMEN
Objective@#To understand current situation and associated factors of brucellosis infection among students in Mongolian middle school in Abaga Banner, and to provide basis for further development of prevention and treatment strategies.@*Methods@#Serological examinations were performed on pupils and middle school students in a Mongolian middle school in Abaga Banner. Questionnaire surveys were used to investigate students knowledge of eating behaviors related to brucellosis infection.@*Results@#A total of 500 primary and middle school students were investigated, and 6 cases of brucellosis were confirmed, and the infection rate was 1.20%. There were 4 cases of male infection and 2 cases of female infection. The infection rate in boys (1.61%) was higher than that of girls (0.79%). Higher proportion was found in 14-year-old group (n=3), accounting for 17.40%. The residence period of 10-15 years includes 6 cases of all infected persons. The number of infections in Narenbaolige Town was 4, accounting for 23.40%. Univariate logistic regression analysis shows that frequent consumption of unsterilized dairy products, milking, processing lambs or slugs and infected cloth The disease was positively correlated (OR=11.80, 139.14, 8.02, P<0.05). Multivariate Logistic regression analysis showed that milking was positively correlated with brucellosis infection(OR=20.19, 95%CI=2.01-202.74, P=0.01).@*Conclusion@#The brucellosis infection of Mongolian primary and middle school students in Abaga Banner is related to a variety of related dietary factors, and its prevention and treatment should be strengthened.
RESUMEN
We identified novel non-HLA-susceptible regions for ankylosing spondylitis (AS) by applying the genome-search-metaanalysis (GSMA) method to combine the previous four AS genomewide scan studies including 479 families with 1175 affected individuals. Three original genomescans were mainly analysed for Caucasian families and one analysed for Han Mongolian families. Ten bins had both Psumrnk and Pord <0.05, suggesting these bins most likely contain AS-linked loci. The 10 bins are 6.2, 16.3, 6.1, 3.3, 6.3, 16.4, 10.5, 17.1, 2.5 and 2.9. The most significant result of linkage was on chromosome 6p22.3-p21.1 (bin 6.2, Psumrnk <0.000417), where HLA loci are located. By addition of a genome scan of Chinese origin, our GSMA result further confirmed the HLA loci as the greatest susceptible region to AS and suggested that non-HLA loci chromosome 16q, 3p, 10q, 2p, 2q and 17p, may also contain AS-linked loci. The novel loci identified in our result give hints to further studies.
