非自杀性自伤行为（NSSI）是指个体在没有自杀意图的情况下，故意对自己身体进行伤害的行为。近年来，NSSI在全球范围内整体呈上升趋势，尤其在青少年群体中日益普遍，这与青少年的年龄特点、心理及生物学特征、社会压力等因素密切相关。有研究表明，NSSI是自杀行为的独立危险因素，不仅对青少年健康造成严重影响，也给家庭和社会带来了沉重的负担。因此，本文通过系统回顾NSSI相关文献，阐述其流行病学现况、影响因素和干预措施，旨在为早期识别高危人群、预防青少年NSSI行为的发生以及制定相应的干预策略提供科学依据。
Non-suicidal self-injury（NSSI）is the behavior in which an individual intentionally inflicts harm on his or her own body without suicidal intent．In recent years，NSSI has been on the rise globally，especially among adolescents，which is closely related to the age characteristics，psychological and biological characteristics，and social pressure．Some studies have shown that NSSI is an independent risk factor for suicidal behavior，which not only poses a serious impact on the health of adolescents，but also imposes a heavy burden on families and society．Therefore，this article systematically reviews relevant literatures on NSSI，mainly elaborating the epidemiological status，influencing factors and interventions．We aim to provide a scientific basis for the early identification of high-risk populations，the prevention of NSSI in adolescents and the development of corresponding intervention strategies
目的 了解广东省罗定市中小学教师的职业倦怠情况,为制定政策提供初步依据。方法 采用中文版Maslach职业倦怠量表(C-MBI)对罗定市42所中小学共590名毕业班教师进行评估。结果 受访者的情感衰竭(emotional exhaustion, EE)和知识枯竭(intellectual burnout, IB)因子分显著高于全国常模(P＜0.05),个人成就感降低(reduced personal accomplishment, PA)因子分显著低于全国常模(P＜0.01)。女性受访者的去个性化(depersonalization, DP)、EE和IB因子分均显著高于男性受访者,PA因子分显著低于男性受访者(P均＜0.01)。结论 广东省罗定市中小学毕业班教师的职业倦怠高于全国平均水平,女性教师的职业倦怠感高于男性教师。
Objective To investigate job burnout among primary and secondary teachers in Luoding city and to provide a preliminary basis for policy formulation. Methods We randomly selected 590 graduating class teachers from 42 primary and secondary schools in Luoding. The outcome variable of burnout was measured by the Chinese Maslach Burnout Inventory for primary and secondary school teachers (C-MBI). Results Emotional exhaustion (EE) score and intellectual burnout (IB) score in respondents were both significantly higher than the national norm used as reference (P＜0.05), reduced personal accomplishment (PA) score was significantly lower than the national norm (P＜0.01). The factor scores of DP, EE and IB were obviously higher in female respondents than that those in the male, while the score of PA was obviously lower (all P＜0.01). Conclusion The level of burnout in these teachers is significantly higher than the national average, and the burnout in female teachers is more serious.
目的 检测抑郁障碍患者血清中IL-2和TNF-α水平,探讨IL-2和TNF-α水平与认知功能情况相关性。方法 采用酶联免疫吸附法(ELISA)检测100例抑郁障碍患者(观察组)和100例健康人(对照组)的血清IL-2、TNF-α的水平,并结合汉密尔顿抑郁量表(HAMD)观察患者抑郁障碍的严重程度,应用Loewenstein 认知评定量表评定患者的认知状态情况进行相关分析。结果 与对照组相比,观察组的IL-2、TNF-α的水平明显更高(P<0.05)。IL-2、TNF-α的水平与HAMD,LOTCA总分呈正相关(P<0.05)。结论 抑郁障碍患者血清中IL-2、TNF-α的水平与抑郁障碍患者的严重程度和认知状态情况呈正相关。
Objective To study the levels of serum IL-2 and TNF-α in depressed patients and theircorrelations with the cognitive function. Methods 100 depressed patients (observation group) and 100 healthy people (control group) were enrolled to this study and we compared their levels of serum IL-2 and TNF-α detected by enzyme-linked immunosorbent (ELISA) from two groups. The correlation analyses of the serum IL-2 and TNF-α levels with the severity of depression of depressed patients observed with Hamilton depression scale (HAMD), and the serum IL-2 and TNF-α levels with the cognitive function evaluated with Loewenstein were conducted. Results The levels of serum IL-2 and TNF-α in the observation group were significantly higher than control group (P<0.05).There were positive correlations between the levels of IL-2 and TNF-α and HAMD scores and between the levels of IL-2 and TNF-α and LOTCA scores (P<0.05). Conclusion The levels of serum IL-2 and TNF-α in the depressed patients were positively correlative with the severity of depression and their cognitive function.
