ABSTRACT
Objective@#To explore the effects of comprehensive intervention measures targeting physical activity, sedentary, sleep and other behaviors on 24 h activity behavior of obese students in vocational colleges, so as to provide a more tailored empirical basis for intervening obese students in vocational colleges.@*Methods@#A quasi experimental design using parallel controlled, randomized grouping was conducted from January to March 2023. A total of 79 first year obese students from a vocational college in Wuxi City were selected as the intervention group (41 students) and the control group (38 students). From April to June, 2023, the control group received no intervention, while the intervention group adopted an information based and behavioral intervention approach to comprehensively intervene in 24 h physical activity, sedentary, sleep and other behaviors (120 minutes each day for 8 weeks).Wherein, information based intervention mainly used paper leaflets and social and learning software to accurately push intervention information, and behavioral intervention mainly concentrated 1 hour of physical exercise and multiple activity behavior requirements every day with the triaxial accelerometer to feedback the objective data of physical activity. Subsequently, from June to July, 2023, a one week post test and follow up survey were conducted respectively.Bouchard diary in physical activity, Weekly questionnaire and triaxial accelerometer were used to record the 24 h activity behavior of both groups of students. T-test and repeated measurement analysis of variance were used to compare the differences of 24 h activity component index time between two groups before and after intervention and examine the changes within each group.@*Results@#Before and after intervention, there was no significant difference in the time of each component index of 24 h activity behavior in the control group. However, repeated measures analysis of variance between the intervention group and the control group revealed statistically significant interaction differences in physical activity, sedentary behavior, sleep and other index time were statistically significant(pre-test and post test: F =6.45, 4.66 ,7.21,7.88; pre-test,post-test and follow up test: F =5.37,5.12,5.43,5.29; P <0.01). During the followup period, compared with the post-test data [(313.25±54.15, 601.88±65.47, 462.83±42.86, 61.92±18.53)min/d], the time of each component (physical activity, sedentary behavior, sleep, other) of the 24 h activity behavior of students in the intervention group rebounded [(298.52± 60.27 , 613.69±68.55, 442.33±45.26, 85.28±20.57)min/d], but it was better than the pre-test data [(230.45±67.42, 720.32±105.63, 369.78±32.31, 119.29±22.17)min/d], and the difference was statistically significant( F =42.46,39.45,33.41,59.43, P <0.01). During the intervention period, the physical activity, sedentary and sleep duration indicators of the intervention group students showed fluctuating patterns in the 4th and 5th weeks.@*Conclusions@#The comprehensive intervention on 24 h activity behavior among obese students in vocational colleges shows significant effectiveness, but its sustainability is insufficient. Considering the characteristics of obese students in vocational colleges, personalized intervention measures should be provided to increase physical activity and sleep time and reduce static activity time, in order to promote students to develop a healthy lifestyle.
ABSTRACT
Objective@#Based on a qualitative research method, the present study aims to explore the negative experiences and real dilemmas of adolescent with depression in the treatment and rehabilitation process, so as to provide references to promote the improvement of the treatment system for adolescent depression in China.@*Methods@#From August 2022 to November 2022, 30 adolescents with depression were selected for in-depth interviews in the inpatient department of child and adolescent psychiatry at Beijing An Ding Hospital affiliated with Capital Medical University by using the purposive sampling method, and the interview data were analyzed by using the Colaizzi method to summarize the themes.@*Results@#The real dilemmas faced by depressed adolescent during treatment and recovery included three aspects:inappropriate family coping (caregivers lacking of correct disease cognition; caregivers lacking of effective coping methods), difficulties in disease diagnosis and treatment (low rate of identification and adverse effect of treatment; medical service failing to satisfy the demands), and barriers to continued schooling (barriers to academic progress and interpersonal communication).@*Conclusion@#Adolescents with depression face real dilemmas in the process of disease treatment and rehabilitation at home, school and medical care. Caregivers disease literacy and caregiving skills should be improved. A collaborative disease management system among family, school, community and medical institutions should be established to promote adolescent depression treatment and social function recovery.
ABSTRACT
@#[摘 要] 目的：探讨长链非编码RNA（lncRNA）LINC01410对胶质瘤A172细胞增殖、凋亡和替莫唑胺（temozolomide, TMZ）敏感性的影响及其机制。方法: 用qPCR法检测胶质瘤细胞系H4、SHG-44、A172和正常星形胶质细胞HA1800中LINC01410表达水平。将LINC01410 shRNA、shRNA control和miR-205-5p 抑制剂（inhibitor）、inhibitor control转染至A172细胞，MTT法、流式细胞术分别检测400 μmol/L TMZ处理后，转染细胞的增殖活性和凋亡水平，WB法检测细胞中Bax、Bcl-2、cyclin D1、p27的表达。在线生物信息学软件LncBase分析LINC01410的靶基因，双荧光素酶报告基因实验验证LINC01410与miR-205-5p的靶向关系。结果: LINC01410在3种胶质瘤细胞中的表达水平均显著高于正常星形胶质细胞HA1800（均P<0.01），以在A172细胞中的表达水平最高（P<0.01）。转染LINC01410 shRNA和TMZ处理后，A172细胞的增殖能力下降、G1期细胞比例和凋亡率均升高（均P<0.01），细胞中Bax、p27表达水平升高而Bcl-2、cyclin D1表达水平下降（均P<0.01）。双荧光素酶报告基因实验证实LINC01410靶向结合miR-205-5p，下调LINC01410促进miR-205-5p表达。转染miR-205-5p抑制剂可逆转下调LINC01410和TMZ处理对A172细胞增殖、周期和凋亡的影响。结论: 下调lncRNA LINC01410可抑制胶质瘤A172细胞增殖、阻滞细胞周期、诱导细胞凋亡且提高对TMZ敏感性，其发生机制似与LINC01410对miR-205-5p的靶向作用有关。
ABSTRACT
Objective@#To analyze the epidemiological characteristics of coronavirus disease 2019 （COVID-19） cases reported in Ningbo from January 22 to February 22, 2020, so as to provide guidance for the prevention and control of the COVID-19 epidemic.@*Methods@#The confirmed cases of COVID-19 reported by Ningbo were selected from National Diseases Prevention and Control Information System to analyze the epidemiological characteristics by descriptive epidemiological method, including time, spatial and population distribution, clinical symptoms and exposure history.@*Results@#A total of 157 confirmed cases of COVID-19 were reported and there was no death. The first confirmed case was reported on January 22. On the incidence curve, the peak was from January 22 to February 4, with a maximum of 15 cases in a single day. The incidence curve presented sustained human-to-human transmission. The number of the cases showed a declining trend from February 5. The confirmed cases were reported in all 10 counties（cities or districts）,among which 69（43.95%）cases were reported in Haishu District. The confirmed cases were mainly 30-69 years old,accounting for 78.34%;were mainly farmers,household workers and retired people,accounting for 59.87%;and were mainly clinically mild,accounting for 87.90%.There were 51 imported cases, accounting for 32.48%. The initial confirmed case was a local case. In the early stage of the epidemic, local cases and imported cases prevalent together,which was due to the outbreak caused by the large-scale buddhist activity on January 19.This event resulted in 67 confirmed cases and 15 asymptomatic cases. There totally reported 22 clusters with 138 （87.90%）confirmed cases. @*Conclusions@# In the early stage of the COVID-19 epidemic in Ningbo, the imported cases and local cases prevalent at the same time. Most of the cases were female, aged from 30 to 69 years, and their occupation were farmers, household workers and retired people. With comprehensive measures taken, the epidemic of COVID-19 in Ningbo have been under control.
