Considering the weak relevance between the stages of C,D,I and O and the weak operability of CDIO theory in teaching,mind map is introduced into CDIO theory to drive medical English teaching.Firstly,how mind map and CDIO theory are mutually complementary is discussed,based on which,along the main clue of CDIO theory,a further discussion is carried out from four levels:conceiving the main structure and content of a passage,designing sentence teaching,implementing vocabulary memorization and operating self-directed learning,all with mind map as an assistance.Moreover,specific cases are used to exemplify how mind map is applied to CDIO medical English teaching.Using.mind maps in CDIO medical English teaching is highly coherent and operable.It helps to integrate the four stages of C,D,I and O and enhances teaching quality and learning efficiency.

Objective To summarize the diagnosis and surgical treatment of mesenteric cyst in children.Methods The clinical records of mesenteric cyst cases from January 2011 to December 2015 were reviewed retrospectively.The diagnosis and treatment options were analyzed, and the prognosis of laparoscopic surgery and laparotomy was compared.Results The main clinical symptoms included abdominal mass, abdominal pain, and abdominal distension.Abdominal ultrasound and/or CT scan were the diagnostic tools in all cases.Traditional laparotomy was performed in 14 cases, while laparoscopy in 7 cases (1 case switched to laparotomy).2 cases had emergency surgery due to acute abdomen, laparotomy and laparoscopy in each case.Simple cyst resections were completed in 14 cases, of which 2 cases with a small amount of residual in the mesenteric root.Intestinal resection and anastomosis were required in other 7 cases.The average time of hospital stay for laparotomy group was 12 days, and 10.14 days for laparoscopy group.There was no significant difference.All patients were discharged without postoperative complications.With 1-4 years follow-up, there was no recurrence.Conclusion The operation for mesenteric cysts depends on the relationship between the cyst and the adjacent bowel or organs, and the overall outcome is favorable.The selective use of laparoscopy will benefit more children.

An experiment of applying bilingual teaching to the course of pathology on the sophomores (students in Grade 2002) was carried out in our department in April 2004. This paper will research the feasibility and necessity of the methodology,ponder the problems in the course of teaching and put forward some suggestions in order to conduct bilingual teaching smoothly on the basis of practice and theory.

This paper explores the teaching methods of medical English terminology from three aspects: vertical and horizontal learning thinking style, DAR(division, analysis and reading) three-step terminology reading process, and diverse comparative vocabulary learning methods. In the teaching, students are guided to establish a framework of terminology learning in a macroscopic level, to interpret medical step by step and to use some of the comparative learning methods in ordinary English vocabulary learning to consolidate the learning and memory of medical terms. Through these three aspects of teaching guidance, students are helped to weave their medical terminology learning framework, to build a terminology learning library, and to turn terminology learning and application into a lasting and effective learning process.

Objective To summarize the etiology,diagnosis and treatment of three cases of duodenal perforation. Methods The data of 3 cases of children with duodenal perforation in our hospital from September 14,2016 to June 20,2017 were retrospectively analyzed. The causes,clinical features and treatment of children's duodenal perforation were summarized. Results A total of 2 males and 1 females aged 2 years,3 years and 5 years were included in the 3 cases. All 3 cases had fever history of upper respiratory tract infection before onset. Acute abdominal pain occurred after oral administration of ibuprofen several times,and all the abdominal plain films prompted pneumoperitoneum. Three cases of perforation sites were duodenal anterior wall,diameter were 0. 5-1 cm. Two cases of small amount of pneumoperitoneum were explored and repaired the duodenal perforation by 3D laparoscopic,1 case underwent laparotomy to repair the duodenal perforation due to a large number of liquid pneumoperitoneum and severe shock. Repair of 3 cases were covered with omentum. Three cases were all cured without anastomotic fistula, ulcer, adhesive intestinal obstruction or other complications. Followed-up in the department of gastroenterology,3 cases had no Helico-bacter pylori infection. Conclusion Repeatedly oral administration of ibuprofen can cause duodenal perfora-tion in children in the short term. Once the digestive tract perforation confirmed,emergency surgical explora-tion is needed. Laparoscopic repair of duodenum perforation is safe and effective and may have a faster recov-ery. We can choose exploratory laparotomy if conditions are not allowed.
