ABSTRACT
Objective:To explore the value of panoramic teaching in clinical practice teaching of department of respiratory medicine.Methods:A total of 35 clinical interns who had a 3-week rotation in the department of respiratory medicine from October 2019 to June 2020 were selected, and they were divided into a control group ( n=17) and a study group ( n=18) according to the order of admission. The control group used traditional teaching, and the research group used panoramic teaching. After the teaching, the teaching effect was evaluated through theoretical knowledge assessment, practical assessment and questionnaire survey. SPSS 19.0 was used for t test. Results:There was no statistically significant difference between the two groups of interns in theoretical assessment [(89.62±4.05) points vs. (90.84±4.12) points, t=-0.891, P=0.379]. The results of practice assessment (case analysis, physical examination of the department, medical history inquiry and skills manipulation) of the study group were significantly higher than those of the control group ( P<0.05). The interns in study group were better than those in control group in such aspects as learning interest, self-learning ability, self-study ability, doctor-patient communication language expression ability, literature review ability, clinical thinking ability, comprehensive analysis ability, knowledge development ability, system diagnosis ability, teamwork ability and teaching satisfaction ( P<0.05). Conclusion:Panoramic teaching can effectively improve the ability of interns to master the clinical diagnosis and treatment of respiratory medicine, improve the teaching effect, and improve the learning ability and clinical competence of interns in the future.
ABSTRACT
Objective:To investigate the role of multimodal neuronavigation intraoperative and sodium fluorescein-guided techniques in microsurgery for intracranial malignant neoplasm.Methods:A retrospective analysis was conducted on 50 patients with intracranial malignant tumors treated by microsurgery from 2016 to 2019 in Inner Mongolia People′s Hospital. Preoperative imaging included computed tomography (CT), computed tomographic angiography (CTA), magnetic resonance imaging (MRI), MRI: MRA, MRV, DWI, PWI, DTI, DTI, MRS sequence scan, and before the operation, they were fused with the functional nervous system navigation workstation of Bo Yilai to make the navigation plan. During the operation, the functional navigation was combined with low dose fluorescein sodium (2 mg/kg) for operation. Intraoperative neuronavigation was used to determine the location of the tumor and its spatial relationship with the pyramidal tract of the main fiber conduction tract and the large blood vessels, and intraoperative yellow fluorescence mode of pentero900 Zeiss microscope showed the boundary between the tumor and normal brain tissue for tumor resection.Results:There were 38 cases of glioma, 10 cases of brain metastasis of lung cancer, 1 case of brain metastasis of renal clear cell carcinoma and 1 case of spindle cell tumor. The accuracy of preoperative neuronavigation was 95%. Compared with the preoperative lesions, MRI of the head was reexamined 3 days after operation to judge the degree of tumor resection. In this group, 38 cases (76%) were totally resected and 12 cases (24%) were subtotal resected. The 6-month survival rate was 85.9%, the 12-month survival rate was 53.1%, the 18-month survival rate was 24.5%, and the survival time was (15.0 ± 3.2) months.Conclusion:Multimodal functional neuronavigation combined with fluorescein sodium staining can locate and label tumors in real time, improve tumor resection rate, and improve the prognosis of brain cancer patients.
