RESUMEN
Objective:To investigate the application effect of the teaching model of massive open online course (MOOC)+small private online course (SPOC) in the undergraduate clinical teaching of Fundamentals of Surgery.Methods:A total of 30 undergraduate medical trainees in the five-year program were randomly divided into experimental group and control group, with 15 trainees in each group. With the chapter of basic surgical procedures as an example, the trainees in the control group received traditional teaching, and those in the experimental group received MOOC+SPOC teaching. Theoretical assessment and surgery simulation were performed at one week after the course to evaluate the teaching effect. SPSS 17.0 was used for the t-test and the chi-square test. Results:The experimental group had a theoretical assessment score of (92.5±6.4) points and a basic skill operation score of (91.7±2.2) points, while the control group had a theoretical assessment score of (85.3±7.3) points and a basic skill operation score of (83.6±6.4) points. The experimental group had an excellent rate of 60% (9/15) in theoretical assessment and 66.7% (10/15) in basic skill operation test, while the control group had an excellent rate of 40% (6/15) in theoretical assessment and 33.3% (5/15) in basic skill operation test. The experimental group had significantly higher scores and grades than the control group ( P<0.05). Conclusion:MOOC+SPOC teaching can significantly enhance the understanding of theoretical knowledge and the mastery of operational skills among trainees and improve teaching effect, and therefore, it has a good application prospect.
RESUMEN
Objective To investigate the prevalence of anxiety and depression one month before idiopathic benign paroxysmal positional vertigo (BPPV) episode. Methods Patients from Vertigo Clinic of Department of Neurology, West Campus, Chaoyang Hospital, were enrolled from January 2014 to June 2016. For patients with first visiting idiopathic BPPV, Hamilton Anxiety Scale and Hamilton Depression Scale were used at the consulting room by an experienced neurologist to reflect the emotional state one month before idiopathic BPPV episode. The occurrence rate of mood disorders was compared with usual model. Results One hundred and eighty five patients with idiopathic BPPV, aged 28 to 82 (57.6±12.0) years, 19.5% (36/185) being male, 80.5% (149/185) being female, were enrolled into this research. No anxiety, probable anxiety, definite anxiety and severe anxiety accounted for 15.1% (28/185), 33.0% (61/185), 47.6% (88/185) and 4.3% (8/185), respectively;no depression, probable depression, definite depression and severe depression accounted for 18.4% (34/185), 48.6% (90/185), 29.2% (54/185) and 3.8% (7/185), respectively;no mood disorders, probable mood disorders, definite mood disorders and severe mood disorders accounted for 11.4% (21/185), 33.5% (62/185), 49.2% (91/185) and 5.9% (11/185), respectively;total definite mood disorders and severe mood disorders accounted for 55.1% (102/185), higher than usual model (14.4%)Conclusion Anxiety and depression is common before idiopathic BPPV episode.
RESUMEN
Intravenous thrombolysis has been proved as an effective therapy for acute ischemic stroke.However,symptomatic intracranial hemorrhage (sICH) occurred after thrombolysis will affect the recovery of patients,even endangers life when it is serious.Therefore,determining the risk factors for sICH after thrombolysis is helpful to select appropriate patients for thrombolytic therapy.The risk factors for slCH after thrombolysis include advanced age,male gender,obesity,higher National Institutes of Health Stroke Scale scores,hypertension,diabetes or higher blood glucose,atrial fibrillation,delayed thrombolysis time,antiplatelet therapy,anticoagulation therapy,and leukoaraiosis.However,some of the risk factors still have conflicting reports.Further large sample clinical studies are needed to confirm them.
RESUMEN
Objective To observe the clinical effects and nursing therapy of Jinchuangkangjungao ointment and infrared therapy in the treatment of chronic skin ulcers .Methods Seventy-five patients with chronic skin ulcers were divided into two groups :the experimental group(n=39) and the control group(n=36) .Jinchuangkangjungao ointment and infrared therapy were applied to the experimental group and the control group underwent conventional treatment ,including debridement ,dressing change and iodine wet compressing .The two group were both given basic nursing therapy .The effect and healing time were observed after 30 days . Results The experimental group′s total effective rate(92 .31% ) was significantly better than that of the control group(69 .44% ) , with significant difference(P<0 .01);The healing time of the experimental group[(11 .98 ± 6 .05)d] was significantly shorten than the control group[(16 .96 ± 7 .13)d] ,with significant difference(P<0 .05) .Conclusion Jinchuangkangjungao ointment combined with infrared therapy had noticeable effect in the treatment of chronic skin ulcers .
RESUMEN
AIM: To investigate whether three-dimensional time-of-flight magnetic resonance angiography (3D TOF MRA) can be used as a reliable screening tool for evaluation of intracranial vascular stenosis and occlusive disease before stent implantation. METHODS: Thirty-three patients with suspected intracranial arterial stenosis received 3D TOF MRA and digital subtraction angiography (DSA) examinations in Chaoyang Hospital Affiliated to Capital Medical University between March 2007 and April 2008,and were included for this study. Two physicians blindly estimated stenosis,patient history,and clinical information of 363 vascular segments from 33 patients,including bilateral internal carotid artery (ICA),anterior cerebral artery (ACA),middle cerebral artery (MCA),posterior cerebral artery (PCA),vertebral artery,and basilar artery (BA). Stenosis was categorized as 30%-49%,50%-69%,70%-99%,and 100%. For each kind of stenosis,sensitivity,specificity,positive predictive value,negative predictive value,K and P values of MRA were calculated,respectively,as compared to DSA. RESULTS: A total of 42 diseased vascular segments were identified. Compared to DSA,for intracranial stenosis 50%-69%,3D TOF MRA showed sensitivity 100%,specificity 96.8%,positive predictive value 62.1%,negative predictive value 100%,K value 0.751,and P value 0.000; For intracranial stenosis 70%-99%,the corresponding value was 100%,98.6%,70.6%,100%,0.821,and 0.000,respectively; For intracranial stenosis 30%-49%,it was 25.0%,99.7%,66.7%,98.3%,0.356,and 0.000,respectively.CONCLUSION: For high sensitivity and specificity to intracranial stenosis 100%,70%-99%,or 50%-69%,compared to DSA,3D TOF MRA is a reliable screening tool for preoperational evaluation of intracranial vascular stenosis and occlusive disease.
