ABSTRACT
ObjectiveTo investigate the difference of ultrasound characteristics between pure mucinous carcinoma （PMC） and fibroadenoma （FA） of the breast. MethodsUltrasound data of 50 continuous patients with breast PMC from January 2012 to January 2021 and 100 continuous patients with breast FA from June 2018 to January 2019 in Sun Yat-sen Memorial Hospital of Sun Yat-sen University were retrospectively reviewed. The ultrasound characteristics of the two groups were evaluated according to the 2013 BI-RADS Ultrasound Atlas， and the differences in age， maximum diameter and ultrasound characteristics between the two groups were compared. ResultsThe median age of PMC patients was 47 years and that of FA patients was 33 years. The age of PMC patients was higher than that of the FA group， and the difference between the two groups of patients was statistically significant （P<0.001）. The median maximum diameter of PMC patients was 2.4 cm， which was greater than that of the FA group （1.8 cm）， and the difference was statistically significant （P=0.001）. Of the PMC， 70% （35/50） were irregular， 82% （41/50） were parallel to the skin， 92% （46/50） had no circumscribed margin， 72% （36/50） were hypoechoic， and 68% （34/50） had enhanced posterior echo. Of the FA， 69% （69/100） were oval or round， 98% （98/100） were parallel to the skin， 54% （54/100） had circumscribed margin， 98% （98/100） were hypoechoic， and 75% （75/100） had no posterior features. The differences in the above ultrasound characteristics between the PMC and FA groups were statistically significant （P<0.001， P=0.001， P<0.001， P<0.001， P<0.001）. There was no significant difference between calcifications and blood flow. ConclusionsCompared with the FA group， patients with PMC are older and the diameter of the lesions are larger. On ultrasound， the morphology and margin of most breast PMC still show the growth characteristics of invasive cancer. Meanwhile， the posterior echo of PMC is enhanced， which is a unique manifestation.
ABSTRACT
To cultivate nursing students with international professional ability for higher vocational education is the key to promote the internationalization of Chinese nursing field. Through analyzing the de-veloping trends and problems of international nursing education in China, based on the international nurses' ability, and study from the nurses training model of Philippines, the international nursing training model was constructed. The paper discussed the selection and retention of students, emphasizing the cultivation of students' international nursing concept and professional English, focusing on the ISPN curriculum and the integration of theory and practice, encouraging the cooperation of international school and faculties sharing, adapting the students-centered teaching methods, and establishing a corresponding sound evaluation system.
ABSTRACT
Objective To improve the mode of clinical medicine postgraduates for specialty degree by OSCE. Methods Clinical medicine postgraduates for specialty degree of Grade 2010 and 2011 were enrolled as research objects. The OSCE scores of the students of Grade 2010 were analyzed and the problems in clinical skills training were summarized. In the last year of clinical training for the clinical medical students of Grade 2011, the reform of clinical skills training was implemented with such improvement measures as publishing last year achievement, analyzing OSCE assessment, strength-ening the supervision of the department of clinical skill training, strengthening the examination as-sessment efforts and organizing collective training. And finally the OSCE scores of the students of Grade 2011 were compared with the scores of the students of Grade 2010. SPSS 19.0 was used to analyze the OSCE scores. Quantitative data were expressed as x±s. T test and Chi-squared test were em-ployed to do statistical analysis, with the inspection level of α=0.05. Result The graduate exami-nation OSCE scores of clinical medicine professional master's degree postgraduates of Grade 2010 display that the failure rate of SP, Physical, Surgical Operation, CPR and Case analysis are more than 5%. After the improvement of clinical skill training, using independent samples t test and chi square test, and contrasting grade 2010, the failure rate of the OSCE score of Grade 2011 in physical examination, surgical operation, site emergency station, CPR station, and case analysis station is significantly improved (P<0.05). Conclusions Improving the mode of clinical skill training by OSCE and performance analysis can effectively enhance clinical competence.
