RESUMEN
Objective To compare the walking abilities of an unilateral transfemoral amputee with four different prosthetic knee joints, to provide a reference for clinical prosthetic prescription. Methods An unilateral transfemoral amputee was asked to wear four kinds of pros-thetic knee joints, mechanical four-bar, pneumatic four-bar, hydraulic and intelligent prosthetic knee joints, and evaluated with Timed Up and Go Test, indoor 6-Minute Walk Test, Static Stand Balance Test and a 1000-meter Outdoor Walking Ability Test, wearing Intelligent De-vice for Energy Expenditure and Activity. Results The amputee consumed the least energy and walked the fastest with intelligent prosthetic knee joint. Conclusion There are some difference in walking ability with different prosthetic knee joints.

RESUMEN
OBJECTIVE@#To describe and analyze the clinical features of nasal respiratory epithelial adenomatoid hamartom and improve the levels of diagnosis and treatment.@*METHOD@#Fourteen cases of nasal respiratory epithelial adenomatoid hamartom confirmed by pathology were collected and analyzed.@*RESULT@#In 14 cases, primary complaint of Hyposmia(or Anosmia)and nasal obstruction were occured in 13 and 11 cases respectively. Four cases had past history of endoscopic sinus surgery because of the diagnosis of nasal polyps. Polypoid neoplasms could be seen in the bilateral olfactory clefts. Sinus CT showed soft tissue shadows in bilateral nasal cavity and mucous membrane thickening in different sinus. Endoscopic sinus surgery were utilized to eliminate focus in all cases. All cases weren t recurred after 2-20 months' following-up visitings.@*CONCLUSION@#Nasal respiratory epithelial adenomatoid hamartom is so rare that clinical and pathological doctors have limited knowledge of it. It has its own characteristics from the clinical symptoms, signs to sinus CT although they are nonspecific. So we should improve the understanding about it to avoid misdiagnosis or missed diagnosis.
