Objective To explore the CT finding of inflammatory myofibroblastic tumor (IMT)in the rare abdominal or pelvic, and compare their pathologies,to improve the accuracy of diagnosis and understanding of the disease.Methods The imaging,clinical and pathological data of 1 7 cases with IMT in the rare abdominal or pelvic were analyzed retrospectively.1 1 cases were performed with plain and enhanced scan,3 cases had plain scan only,and 3 cases had enhanced scan only.Results Among the 1 7 cases,8 cases were male,9 cases were female;1 5 cases were single,2 cases were multiple;4 cases were located in the stomach,colon or bladder,3 cases located in spleen,1 case located in kidney or urachus.Among those,2 lesions located in the colon cavity presented as soft tissue, it was difficult to distinguish the lesion from the adjacent intestinal contents since the small intestinal hypotonic CT examination was not performed and the intestinal filling was poor,thus those lesions were missed diagnosed with CT plain scan.The remaining 15 cases presented as soft tissue density as well,among those,9 cases presented with clear border while 6 cases with blurred border;the peripheral fat space of 4 cases were blurred and presented as infection and exudation,5 cases were accompanied with lymph node enlargement around the lesion;the density of 10 cases were uneven,among those,1 IMT lesion in bladder presented with linear calcification,1 IMT lesion in gastric antrum presented with nodular ossification in the center,9 cases showed obvious necrosis and cystic degeneration;5 cases showed even.After contrast administration,the lesions were enhanced mildly,moderately or significantly.The enhancement type were various,presented as uniform or nonuniform delayed enhancement.Vessel shadow was observed in 10 cases during arterial phase.All of the 17 lesions were primary, and no recurrence was found during follow-up.Conclusion The feature of IMT in the abdominal or pelivic including the following:the peripheral area of the lesion presenting as infection or exudation,the lesion showing uniform or nonuniform delayed enhancement, and vessel shadow observed in the lesion during arterial phase;in addition,calcification of the edge or central of the lesion occasionally happens,while ossification of the lesion is quite rare.

The proportion of the elderly population in China is increasing.How to truly achieve elderly care and medical services through medical-nursing combined care is an important problem that urgently needs to be solved.Taking Beijing as an example,this paper analyzed the development situation of medical-nursing combined care in Beijing,conducted field research on the three main models of medical-nursing combined care in Beijing,as well as summarized the difficulties and challenges faced by different models from the perspective of organizations and institutions.It suggested to further integrate and coordinate the Beijing-Tianjin-Hebei policies of medical-nursing combined care,accelerate the implementation of long-term care insurance,strengthen the professional training of elderly care talent teams,enhance the standardized construction and supervision of elderly care institutions,and vigorously develop technological and intelligent elderly care.
