ABSTRACT
Objective To explore the application value of comparative imaging combined with multimedia teaching in the five-year undergraduate intemship teaching of nuclear medicine.Metbods 70 undergraduates internship in the nuclear medicine department of our hospital from June 2017 to February 2018 were divided into the control group and experimental group,35 in each group.The control group adopted traditional teaching method,and the experimental group adopted comparative imaging combined with multimedia teaching for internship teaching.The theoretical test scores,the evaluation of the self-perception of the teaching process and the teaching feedback of the two groups were compared.Results The theoretical test scores of the experimental group students were significantly higher than those of the control group,including the noun explanation [(26.60 ± 0.51) vs.(22.20 ± 0.58)],the short-answer question [(26.80 ± 0.37) vs.(22.40 ± 0.60)],the essay question [(36.00 ± 0.71) vs.(27.40 ± 1.03)] and total score [(92.40 ± 0.93) vs.(71.80 ± 0.37)].The satisfactions with the evaluation of the self-perception in the teaching process and the teaching feedback in the experimental group were also much better than those of the control group.Conclusion The application of comparative imaging combined with multimedia teaching in the practice teaching for undergraduate students in nuclear medicine could effectively improve the clinical practice teaching quality and actively promote the development of the teaching of nuclear medicine.
ABSTRACT
Objective To investigate the treatment of acute obstructive colorectal cancer.Methods The clinical data of 26 cases with acute obstructive colorectal cancer were analysed retrospectively and relevant literatures were reviewed.Results Radical right hemicolectomy was performed in 9 patients with obstructive right colonic cancer.Among 17 patients with obstructive left colorectal cancer,one-stage radical resection was perfomed in 12 cases,including one-stage anastomosis in 4 cases and Hartmann's operation in 8 cases.Palliative colostomy was performed in 3 cases.Right hemicolectomy and sigmoid colon loop colostomy was performed in 1 case of rectum cancer with ascending colon strangulation.One case refused surgery.Two cases died of MODS and 1 case with inflammatory ileus recovering from conservative treatment after operation.In the course of disease,septic shock and MODS happened in 3 cases,lung infection in 5 cases,heart disease in 2 cases and Hypoalbuminemia in 16 cases.Conclusions One-stage radical colectomy and anastomosis should be performed in patients with obstructive right colonic cancer.In order to reduce toxin absorption and prevent the deterioration of disease,Bowel decompression and removal of inflammatory exudate should be performed in patients with obstructive left colorectal cancer according to the damage control theory.Then effective and safe operation should be chosen in accordance with patients' status.Anti-infection and nutrition support treatment must be strengthened after operation.
