Objective To explore suitable anatomy for teaching methods for international medical students from multiple sources. Methods Thirteen international medical students of 6-year-programme (grade 2011) and 19 Chinese medical students of five-year-programme were taught with Chinese system anatomy(module) textbooks and Chinese-English bilingual textbook(as reference) by three-step bilingual anatomy teaching method , which includes previewing anatomical vocabulary , teaching Chinese and foreign students in the same class. Teaching effect was international tested by scale separating teaching and examing and questionnaire survey. SPSS 10.0 was used to do statistical analysis and t test was used to compare the score of Chinese medical students and international med-ical students. P<0.05 students for statistic difference. Results Average test scores of international and Chinese students in the same class were 86.2 and 88.1 respectively, with no significant difference (P﹥0.05). 92.3%(12/13) international students were satisfied with this teaching method and the same class teaching for Chinese and international students . Conclusions Three-step bilingual anatomy teaching method in the same class may be more suitable for international students from multiple sources and this teaching method is worthy of further study and practice.

Posttransplant lymphoproliferative disorder(PTLD)is one of the more serious complications of organ transplantation.From October 2021 to December 2022, 3 patients with hepatic portal PTLD were hospitalized.Conventional ultrasonography hinted at hypoechoic area in porta hepatis.Enhanced CT revealed heterogeneous enhancement of soft tissue density in porta hepatis.PET/CT indicated higher metabolism of hilar mass.Two patients underwent contrast-enhanced ultrasound. "Fast-in-and-fast-out" sign(n=1)and no enhancement in all stages(n=1)were noted.Pathological examination revealed T/NK cell lymphoma(n=2)and B cell lymphoma(n=1). In conjunctions with previous literature reports, conventional ultrasound is frequently employed for detecting early cases of PTLD during clinical follow-ups.Contrast-enhanced ultrasound and enhanced CT may aid in making a differential diagnosis of PTLD.And PET/CT has high diagnostic accuracy for PTLD.
