ABSTRACT
Objective To make correct diagnosis for Rathke cleft cyst(RCC)and cystic pituitary adenomas(CPA)through retrospective analysis of characteristics of MRI.Methods RCC (n=30)and CPA (n=30)confirmed by surgery and pathology were analyzed retrospectively.Following characteristics of lesions were observed:morphology,size,location,range,T1WI signal intensity and patterns of enhancement,presence of intracystic fluid level,septum,nodule,hypointense rim on T2WI and change of the pituitary stalk.The independent sample t-test and χ2 test were used respectively to analyze differences between two groups of continuous variables and categorical variables.Results Most of RCC were oval,less than 2 cm3,under the optic chiasm and within the bilateral cavernous sinus,various for signal intensity,without or with thin-walled contrast enhancement.Intracystic nodule accounted for 40% of cases and there were double cystic nodules in 1 case.Obvious contrast enhancement of intracystic nodule was found in 1 case.Pituitary stalk was in center.Most of CPA were snowman shaped,bigger than 2 cm3,off middle line location,with compression of the optic chiasm and sellar base,had thick-walled contrast enhancement,with intracystic fluid level and septum,had hypointense rim on T2WI.The pituitary stalk was shifted.Conclusion The MRI findings of RCC and CPA are significant differences in the shape,size,intracapsular structure,enhanced performance and changes of surrounding structure.
ABSTRACT
Objective To investigate the prevalence and risk factors of chronic kidney disease (CKD) in Chengdu urban population and the prevalence of CKD in risk population.Methods Questionnaire (anamnesis,smoking,drink) of risk factors of CKD and somatoscopy (blood pressure,body height and body weight) were caried out in railman of Chengdu urban.Their blood and urine indicators (blood sugar,blood lipid,blood uric acid,blood creatinine,uromicroprotein/creatinine ratio,routine urine examination,etc) were measured.The prevalence and risk factors of CKD in Chengdu urban population and the prevalence of CKD in risk population were elucidated.Results Eligible data of 5326 subjects were enrolled in the study.After the adjustment of age and gender component,the prevalence of albuminuria was 11.54％,reduced eGFR was 5.54％,hematuria was 3.87％,and CKD was 18.32％; the recognition was 1.93％.In addition,the prevalence of albuminuria was respectively 23.79％,28.00％,14.08％; prevalence of reduced eGFR was respectively 4.76％,4.53％,3.26％; prevalence of hematuria was respectively 2.94％,3.20％,2.37％ in 3098 people with hypertension,diabetes or hyperlipaemia.Independent risk factors of albuminuria were female,hypertension,diabetes,hyperlipemia and high BMI.Independent risk factors of reduced eGFR were female,age,hyperuricemia and hypertension.Drink was negatively correlated with reduced eGFR.Independent risk factors of hematuria were female and age.Conclusions The prevalence of CKD is quite high and the recognition rate is low in the Chengdu urban populaton.Risk factors of CKD are age,female,diabetes,hypertension,hyperlipemia,hyperuricemia and high BMI.Control of the development of metabolic disease can reduce the CKD.
