ABSTRACT
Objective:To explore the application effect of massive open online course (MOOC) combined with peer mutual assistance in cardiopulmonary resuscitation teaching.Methods:A total of 140 students in the same class of Batch 2015 were divided into the experimental group and the control group. In the teaching of cardiopulmonary resuscitation, the experimental group was based on the MOOC teaching platform, watched videos and topic tests before class, and used the peer mutual assistance in class. While the control group adopted traditional classroom teaching mode. The teaching effect of the two groups were evaluated by comparing the operation assessment scores and questionnaire survey of students' satisfaction with teaching. SPSS 22.0 was used for t-test and Chi-square test. Results:The operating assessment score of the experimental group was (82.20±2.31), and the operating assessment score of the control group was (75.80±1.72). The difference was statistically significant ( t=3.27, P<0.05). The questionnaire survey showed that the course satisfaction and learning motivation of the experimental group were better than those of the control group. In learning burden, the two groups had similar results ( P=0.739). Conclusion:MOOC combined with peer mutual assistance in cardiopulmonary resuscitation teaching can help students better master skills, improve students' course satisfaction and learning motivation, without increasing their learning burden.
ABSTRACT
Objective To investigate the effect of glutamine (GLN) treatment on neurobehavioral outcome,brain edema and inflammatory response in rats after traumatic brain injury (TBI),and to find out the role played by autophagic response in this effect.Methods Rat models with TBI in this study were established using Feeney's method.One hundred healthy male SD rats were randomly divided into five groups (n =20) to receive sham operation (group Sham),TBI (group TBI),TBI and glutamine treatment (group TBI+GLN),TBI amd autophagy inhibitor 3-methyladenine (group TBI+ 3-MA),and TBI,GLN and autophagy inhibitor (group TBI+GLN+3-MA).We measured the rats' behavioral outcomes by modified neurologic severity score (mNSS) tests at day 1,3,7 and 14 after intervention.Brain water content was measured with wet-dry weight method.The serum levels of tumor necrosis factor-α (TNF-ct),interleukin (IL)-1 and IL-4 were tested using enzyme linked immunosorbent assay.The expressions of autophagy-related factors (LC3-Ⅱ,Beclin-1) in TBI cerebral cortex were tested with Western blot.Results Compared with the Sham group,the other four groups had significantly increased levels of brain edema,mNSS,serum inflammatory factors and cerebral LC3-Ⅱ and Beclin-1 (P=0.00).Compared with the TBI group,the TBI+GLN group had less severe brain edema and improved mNSS,lower levels of TNF-α [(57.71 ±9.69) pg/ml vs.(83.37± 12.81) pg/ml,P=0.01] and IL-1 [(39.46±8.60) pg/ml vs.(69.04± 10.48) pg/ml,P=0.00],higher levels of IL-4 [(68.72± 11.18) pg/ml vs.(35.75 ± 8.40) pg/ml,P =0.04],and upregulated expressions of LC3-Ⅱ and Beclin-1 (P=0.01).Compared with the TBI+GLN group,the TBI+GLN+3-MA group had severer neurofunctional impairment,brain edema and inflammation (P＜ 0.05).Conclusions Treatment with GLN markedly reduced brain edema and improved neurobehavioral outcomes in rats with TBI by inhibiting inflammatory response in the central nervous system.The mechanism might have been the activation of the autophagic response.
ABSTRACT
Septic shock is one of the most serious diseases threatening the critically ill patients in Intensive Care Unit.How to improve the survival rate has now been most concerned and directed by critical care doctors.For that case,it is necessary to summarize and investigate the clinical cases about how to manage elderly patients with septic shock.
ABSTRACT
Sixty patients with piriformis syndrome were treated mainly by electroacupunture, Tuina plus TDP irradiation. After 10 treatments, among 60 patients, 41 cases were cured and 19 cases were improved.
ABSTRACT
Objective To discuss the value of video-assisted thoracoscopy plus minithoracotomy (VATM) in the management of thoracic diseases. Methods An 1.5 cm incision was made along the middle axillary line at the 7th costal interspace on the diseased side to introduce the thoracoscope. After the exploration of intrathoracic lesion, another incision 5~8 cm in length close to the lesion was made. The thoracic cavity was opened by way of the costal interspace. Surgical performance of exploration, dissection, hemostasis and suture was performed under thoracoscope and direct vision by using routine surgical instruments and thoracoscopic instruments. A total of 43 cases of VATM were carried out. Results The operation time was 40~150 min (mean, 67 min). The length of incision was 5~8 cm (mean, 6 cm). The chest drainage lasted 2~5 d. No postoperative complications occurred. The postoperative hospital stay was 5~8 d (mean, 6 d). Follow-up found no recurrence for 3~22 months in 18 cases of spontaneous pneumothorax and pleural effusion, and found no recurrence, distant metastasis or incision implantation for 5~20 months in 3 cases of lung cancer receiving either lobectomy or wedge resection. Simple biopsy of tumor was conducted in 6 cases of lung cancer, who obtained chemotherapy or gamma knife radiotherapy postoperatively and survived 5~21 months. Conclusions VATM is practical, minimally invasive and safe. By using routine surgical instruments it has an optimistic outlook.
