Objectives: The objective of this study is to explore the relationship between college students’ emotion management ability and mental health; Methods: A total of 1000 college students from four universities in our city were selected as the object of the study, the emotion management ability of 1000 college students was analyzed by means of questionnaire, and the mental health status of college students was measured with symptom checklist (SCL)-90, the average scores of the five dimensions of college students’ emotional management ability are classified as follows: controlling negative vent > rational regulation > seeking outside support > controlling negative suggestion > positive remedy; Results: The results showed that there were obvious negative correlations between the three factors and the SCL-90 factors, such as the rational control of college students, the control of negative implications, and the control of negative venting, however, there is only a negative correlation between college students’ seeking outside help and interpersonal, paranoid, psychotic, and depressive factors, positive remedies were negatively correlated with the symptoms of compulsion, psychosis, and depressive factors, while positive remedies and paranoia factor and hostile factor are obviously related; Conclusions: In the investigation of college students’ emotional management ability, the five dimensions are closely related to their mental health status, therefore, we should pay attention to the cultivation of college students’ emotional ability and encourage them to participate in some meaningful activities to improve their mental health.

Psoas abscess has been classified into two types, namely the primary abscess, which presents with infection limited to the psoas muscle itself and is mostly pyogenic, and the secondary abscess, in which associated intra‑abdominal or skeletal conditions are present; Staphylococcus aureus is the most common causative organism in primary cases, while secondary cases are mostly associated with adjacent tissue infection, tuberculosis of the spine, or intra‑abdominal pathologies, with lumbar spine tuberculosis—due to its close anatomical association with the psoas muscle—being involved in 75%–83% of cases, and bilateral cases of psoas abscess being uncommon in the context of tubercular spinal disease.
