Objective:To explore the feasibility and preliminary effect of improving the comprehensive quality of medical students by introducing the teaching model of cleft lip and palate treatment platform in medical education.Methods:A total of 40 grade two undergraduates of Shantou University medical college were randomly divided into experimental group ( n=20) and control group ( n=20). The students in the experimental group were the volunteers of Cleft lip and palate treatment center, receiving the characteristic idea and methods in clinical teaching. The control group received conventional teaching. The evaluation indicators, including the intellectual quality (60 points), moral quality (15 points), humanistic quality (5 points), physical and mental quality (10 points), social practice (10 points), were quantified by fuzzy evaluation method and a professional evaluation team was set up to evaluate the effect of teaching. SPSS 19.0 was used to perform t test for comparison between the two groups. Results:The average scores of the above items in the experimental group were respectively (51.477±2.381), (10.613±0.169), (4.228±0.124), (8.677±0.296), and (8.565±0.421), and the average total score was (83.559±2.333); the average scores of above items in the control group were respectively (49.746±3.176), (10.268±0.266), (4.008±0.195), (8.207±0.354), and (7.575±0.321), and the average total score was (79.804±3.510). Statistical difference was found in all scores except the intellectual quality score between the two group ( P<0.05). Conclusion:Though no significant difference was found in the intellectual quality, the other qualities have played important roles in improving medical students' comprehensive quality. It is significant to improve the medical students' comprehensive quality by the method of cleft lip and palate treatment platform.

Objective To study the invasive histopathological features of papillary thyroid carcinoma(PTC)with tall cell variant(TCV).Methods A retrospective analysis of 19 170 cases of PTC in Ruijin Hospital,Shanghai Jiao Tong University School of Medicine from January 2018 to May 2023 was performed to analyze and the clinicopathological features between TCV-PTC group and classic PTC(cPTC)group.Results Pathological results showed 1 380 cases in TCV-PTC group and 15 578 cases in cPTC group.TCV-PTC had higher proportion and(or)mean value in patients'age,extraglandular invasion,nerve invasion,vascular invasion,maximum diameter of cancer focus,multifocality,lymph node metastasis and BRAF mutation,but the proportion of patients with coexistent Hashimoto's thyroiditis was lower than cPTC,and all results had significant difference(P<0.05).Conclusions Compared with the cPTC,TCV-PTC has stronger local invasive characteristics and lymph node metastasis rate,which provides the basis for the subsequent clinical treatment.
