Interaction in classroom teaching is a bilateral activity that is difficult to control. Teachers and students are the two main aspects to realize the synchronization of teachers and students' thinking. For teachers, teachers should first make full use of multimedia resources, bring a colorful courseware into class-room teaching; secondly, teachers should stimulate students' interest in a reasonable way, so as to inject vitality into the classroom teaching; finally, teachers should mobilize the students' thinking and carefully regulate the changes in thinking between teachers and students through a proper teaching methods. In terms of students, students should not only give full play to their initiative, but also actively cooperate with teachers in order to realize the thought synchronization between teachers and students in classroom teaching and learning interaction and ultimately achieve the desired results.

Objective To analyze MRI features of breast intraductal papilloma,to improve the acquaintance of this disease.Methods The preoperative MRI images (T2 WI-SPAIR,DWI,ADC,TIC and MIP)of eight patients with breast intraductal papilloma confirmed by surgery were reviewed retrospectively,which were compared with the postoperative pathology.The morphology,distribution, enhanced methods and signal characteristics of the lesion were summarized.Results Of 8 cases,the lession was dormant,and MRI revealed three patterns:the first type was occult papilloma,which presented distention of ducts and no solid nodule in 3 cases (37.5%);the second type showed tiny nodules in bar-like dilatation of ducts in 3 cases (37.5%);and the third type presented small round nodules scattering distribued in terminal ductules in 2 cases (25%).The maximum diameter of nodular lesions was 0.4-1.0 cm(average 0.7 cm).The lesions on T2 WI-SPAIR showed equal signal intensity or mixed signals with isointensity/hypointensity,and dilatation catheter.enhancement. The ADC and TIC value were various,therefore,diagnosis of the tumor should be combined with morphology and associated symptoms. Conclusion At early stage,the occult focus of breast intraductal papilloma can be sensitively detected and localized on MRI.It reveals that MRI has advantage in showing morphology of lesion and functional imaging,which is of important value in clinical diagnosis and early treatment.

Objective To investigate the correlation between helicobacter pylori infection and pathological characteristics of gastric mucosal in the elderly.Methods Retrospective analysis was conducted in 278 patients with benign upper gastrointestinal disease from January 2014 to June 2014.The patients were examined by endoscopy and 13C-UBT,and divided into elderly group (aged 60 years and over,n=111) and non-elderly group (aged＜60 years,n=167).The relationships between Hp infection and pathological changes in gastric mucosal tissue (severe chronic inflammation,neutrophil infiltration,lymph follicles,gastric gland atrophy,intestinal metaplasia) were analyzed.Results There was no significant difference in helicobacter pylori infection rate between the elderly group and non-elderly group [27.0％ (30/111) vs.36.5％ (61/167),P＞0.05].The rate of gastric gland atrophy was higher in elderly group than in non-elderly group [13.5％ (15/111) vs.6.0％ (10/167),P=0.028].The rates of severe chronic inflammation,neutrophil infiltration,lymph follicles,gland atrophy and intestinal metaplasia were 73.6％,70.3％,14.3％,18.7％,29.7％ in patients with helicobacter pylori infection,which were higher than those in patients without helicobacter pylori infection (19.8％,3.2％,0.5％,4.3％,8.6％,respectively,all P=0.000).Removing the factor of Hp infection,the rates of glands atrophy and intestinal metaplasia were higher in elderly group than in non-elderly group (8.6％ vs.0.9％,43.3％ vs.23.0％,P=0.013 and 0.045).Conclusions Helicobacter pylori infection correlates with severe chronic gastric mucosal inflammation,neutrophil infiltration,lymph follicles formation.Gland atrophy and intestinal metaplasia are related to the Hp infection,and age is also their influencing factor.
