BackgroundDepression is the main risk factor leading to suicidal ideation among college students. This study focused on observing and assessing how the combination of Five-Element Music and Eight-Section Brocade affected depression levels among medical students attending higher vocational colleges.MethodsFrom a total of 1,030 medical students studying in higher vocational colleges, we selected 160 students who showed depressive symptoms and met the specific criteria for the study. We used the SDS scale to identify these students and made them the participants of our experiment. Participants were randomly divided into four groups: the music intervention group (listening to traditional Chinese Five-Element Music for 15 min daily), the Eight-Section Brocade intervention group (practicing the Eight-Section Brocade exercises once daily, approximately 15 min), the combined intervention group (first practicing the Eight-Section Brocade exercises once, then listening to music for 15 min), and the control group (no intervention). Each group consisted of 40 participants. The three intervention groups (excluding the control group) underwent continuous intervention for 4 weeks. The SDS, SAS, and PSQI scales were used for evaluation before and after the intervention.ResultsExcept for the control group, the SDS, SAS, and PSQI scores of the other three groups were lower after the intervention than before the intervention (p 0.05). However, the students who did both music and Eight-Section Brocade showed significantly lower scores than those who did only one activity (both p

Triple-negative breast cancer (TNBC) is more aggressive than other breast cancer subtypes. Collagen type IV alpha 2 (COL4A2), a major component of the basement membrane, dynamically influences a wide range of biological processes, including cancer pathogenesis and progression. This study evaluated the effects of COL4A2 siRNA delivered by lentiviral vector to TNBC cells. COL4A2 siRNA lenti-viral vector was constructed and transfected into MDA-MB-231 and MDA-MB-468 cells. The COL4A2 mRNA levels were quantified by RT-PCR. CCK8 assay was performed to evaluate cell proliferation and migration. Cell migration and invasion assays were carried out using Transwell. Cell apoptosis and cell cycle analyses were conducted using flow cytometric approach. We found that COL4A2 mRNA levels were significantly down-regulated in MDA-MB-231 and MDA-MB-468 cells after transfection with COL4A2 siRNA. Furthermore, cell migration and proliferation were significantly decreased and the cell cycle was arrested. Our results indicated that COL4A2 siRNA significantly suppresses the migration and proliferation of TNBC cells. Inhibition of COL4A2 may be a new target for the prevention and treatment of TNBC.
