Objective To explore the disease spectrum characteristics of hospitalized children having joined new rural cooperative medical system (NCMS) in Jinjiang, in order to provide reference for developing disease prevention and control measures for the children. Methods The disease spectrum of NCMS hospitalized children under 14 years old in Jinjiang from January to December 2013 were analyzed. Results The NCMS hospitalized children's disease attack was related to age and sex. Children in different age stages had different ranks of disease constitution, but respiratory and digestive system diseases always ranked the top 3 in each age group. The top 5 system diseases affecting children's health were respiratory diseases ( 63 . 60%) , digestive diseases ( 11 . 04%) , certain infectious and parasitic diseases (5.41%), certain conditions originated in perinatal period (3.17%), and certain consequences caused by injury, poison-ing and external causes (2.76%);The top 5 system diseases affected 85.99%of the total hospitalized children. Regard-ing to single disease rank, the top 5 diseases were all respiratory system diseases, (unspecified) bronchial pneumonia (22.83%), (unspecified) acute tonsillitis (9.26%), (unspecified) acute upper respiratory tract infection (8.99%), (unspecified) acute bronchitis (8.82%) and unspecified pneumonia (5.38%); The top 5 diseases affected 55.28% of the total hospital-ized children. Conclusion Respiratory disease is the major disease threatening the children's health in Jinjiang. It is suggested that medical and health resources be adjusted rationally, specific effective methods and measures be taken to prevent respiratory diseases, and relevant prevention and control measures be developed based on the disease constitu-tions of children in different age groups.

Objective To observe and measure the morphology of diaphragm sella under MR imaging and its parameters in patients with pituitary adenoma,and to explore its clinical significance.Methods Forty-seven patients with pituitary adenoma,admitted to our hospital from March 2012 to April 2013,were collected in our study; the traditional MR imaging of all patients were obtained preoperatively and postoperatively,and 3D-GE sequence scanning was added preoperatively.The parameters of diaphragm sella were measured and compared between patients existed invasion and without invasion,and between patients enjoyed total resection and non-total resection; and the correlation between each two parameters were analyzed.Results Concave,horizontal and convex diaphragm sellae (n=3,10 and 34,respectively) were observed; tumor height of the patients whose diaphragm sella was convex was significantly higher than that of the concave cases ([28.82±11.29] mm vs.[13.57±4.42]mm,P＜0.05).The size and elevation angle of the diaphragmal opening were positively correlated with tumor height (r=0.224,P=0.003; r=0.586,P=0.000).The size ofdiaphragmal opening in the invasive group was significantly larger than that in non-invasive group ([10.30±5.79] mm vs.[5.55 ±3.29] mm,P=0.002).The size of diaphragmal opening in non-total resection group was significantly greater than that in the total resection group ([5.58±4.14] mmvs.[11.04±4.80] mm,P=0.000),and the width of diaphragrnal opening was negatively correlated with tumor resection ratio (r=-0.576,P=0.020).Conclusions Diaphragrna sellae could be displayed satisfactorily in contrast-enhanced 3D-GE MRI.The size of the diaphragmal opening and the elevated angle of drua besides diaphragrnal opening are positively correlated with tumor height.The size of diaphragmal opening of the invasive pituitary adenoma patients is larger than that ofnon-invasive ones.The larger the diaphragrnal opening size,the more difficult the tumor being totally resected by transsphenoidal approach.
