ABSTRACT
Objective:To explore the relationship between emotional trauma and depressive symptoms.Methods:In November 2021, a total of 1 650 university students were assessed using scales including childhood trauma questionnaire (CTQ), distress tolerance scale (DTS), rumination response scale (RRS) and the depression anxiety stress scale (DASS). SPSS 20.0 and AMOS 25.0 software were used to analyze the data with Spearman correlation analysis, Mann-Whitney U test and mediation analysis. Results:The differences of DTS, RRS and DASS were significant between high and low trauma group(all P<0.01). Emotional trauma (16.70(6.09)) was negatively correlated with distress tolerance(10.95(2.15)) ( r=-0.26, P<0.01), and positively correlated with rumination(39.51(10.74)) and depression(4.93(5.76)) ( r=0.31, 0.38, both P<0.01). The testing of mediating effect indicated that emotional trauma had direct effect ( β=0.20, P<0.001) and indirect effect on depression through distress tolerance and rumination. Conclusion:Emotional trauma, distress tolerance and rumination are important factors influencing depression, and it could provide guidance for undergraduate psychological intervention of depression.
ABSTRACT
Objective: To observe the effect of strengthening qi and nourishing yin recipe (SQNY recipe) on the expressions of estrogen receptor ? (ER?) and CyclinD1 of Lewis lung cancer in C57BL/6 mice with immunohistochemistry, and discuss the mechanism of its anti-proliferation and anti-metastasis effects, and analyse the correlation between ER? and CyclinD1. Methods: Twenty-four C57BL/6 mice were randomly divided into three groups. They were all transplanted with Lewis lung cancer cells, and received the interventions the next day as follows: tumor-bearing control group was fed with 0.9% NaCl, and TCM group was treated with SQNY recipe, and DDP group was given intraperitoneal DDP injection. All of mice were killed on the 20th day, weighed the tumor and counted lung metastases to calculate the inhibition rates of tumor growth and metastasis. The expressions of ER?, CyclinD1 in tumor tissues were detected by immunohistochemistry. Results: The inhibition rates of tumor growth and metastasis were 35.02% and 54.20% in TCM group, and were 41.18% and 39.02% in DDP group, respectively (all P
