ABSTRACT
Objective@#To explore the relationship among jogging risk perception, jogging risk behavior and the incidence of jogging risk, so as to provide a feasible way to reduce the risk of college students extracurricular jogging exercise.@*Methods@#The method of convenience sampling was used to conduct a follow up survey among 470 college students at a university in Beijing participating in extracurricular jogging exercise and the sports world campus app was used to record and monitor jogging exercise. During the tracking period, the jogging related information was counted once a month, a total of 6 times. At the same time, three questionnaires were distributed in three stages to collect relevant information. SPSS 26.0 was used for the descriptive analysis, and AMOS 22.0 was used for correlational analysis.@*Results@#The risk rate of extracurricular jogging exercise of college students during the past academic year was 71.06 %, score of knowledge on jogging risk was(3.68±0.59), was (3.25±0.91)for jogging injury, and was( 3.23± 0.96)for jogging related disease. Significant negative correlation between college students jogging risk perception and jogging risk behavior ( r =-0.34), negative correlation between jogging risk perception and the incidence of jogging injuries ( r =-0.27), and positive correlation between jogging risk behavior and the incidence of jogging injuries ( r =0.28) were observed( P <0.01). PE(physical education) class was the main way of obtaining the knowledge about jogging risks among college students(43.40%). @*Conclusion@#College students show high vulnerability for extracurricular jogging related risks, and low level of perception of jogging risks and jogging injuries. Relevant measures need to be taken to improve the cognitive level of running risk among college students, so as to reduce the incidence of running risk.
ABSTRACT
Objective To explore the effects of hsa-miR-96 to A549. Method A549 were transfected with miR-96 inhibitor/mimics and shRNA-mTOR. The proliferation were detected by MTT,the expression of p21, cyclin D1,p-4E-BP,S6K were detected via RT-PCR and WB. The luciferase assay were used to anaylse the target of miR-96. Result With or without metformin treated,up-regulated the expression of miR-96 could inhibit A549 proliferation,increase p21 expression and decrease cyclin D1 expression instead. The results may related with G1 arrest which induced by miR-96 up-regulation. The ratio of firefly fluorescence value/Renilla fluorescence value was lower than that in wild type NC or mutant group. Conclusion miR-96 target with mTOR to inhibit the growth of A549.
ABSTRACT
<p><b>OBJECTIVE</b>To summarize our experience with video-assisted thoracoscopic (VATS) removal of esophageal leiomyoma located with endoscopy during operation.</p><p><b>METHODS</b>Between January 2006 and December 2010, 55 patients with esophageal leiomyoma underwent VATS enucleation. The surgical procedure was similar to that of open thoracotomy with intraoperative endoscopic location of the tumor and examination of the mucosal integrity especially for tumors less than 1 cm in diameter.</p><p><b>RESULTS</b>Of the 55 patients undergoing VATS tumor removal, 54 patients completed the procedures smoothly, and 1 patient experienced ventricular fibrillation during the operation to require an open thoracotomy. Endoscopy was used in 38 patients during the operation. VATS enucleation differed significantly from open thoracotomy in the volume of bleeding, postoperative fasting days and postoperative hospital stay (P<0.05). The symptoms were completely relieved after the operation without postoperative complications. The patients were followed up for 8 to 59 months (mean 23.0 months) and no recurrence was found.</p><p><b>CONCLUSION</b>VATS removal of esophageal leiomyomas is minimally invasive, safe and effective and can serve as the primary option for surgical removal of esophageal leiomyomas.</p>
