Association between nocturnal sleep duration combined with snoring exposure and SGA，LGA in the first trimester of pregnancy based on birth cohort / 安徽医科大学学报

Objective @#To investigate the correlation between nocturnal sleep duration combined with snoring in the first trimester of pregnancyand small for gestational age(SGA) ，large for gestational age(LGA) ．@*Methods @#Multi- variate Logistic regression model was used to analyze the association between nocturnal sleep duration ，snoring， their combined effects and SGA，LGA. @*Results @#Compared to nocturnal sleep duration 7 to 9 h in the first trimester of pregnancy，sleep duration＜7 h was positively correlated with SGA in male newborn( OR = 4. 22，95% CI : 1. 69 - 10. 52) ; After stratified by snoring，the sleep duration of snoring women＜7 h was positively correlated with SGA ( OR = 5. 68，95% CI : 1. 02－31. 51) ，and the sleep duration of non-snoring women＜7 h was positively correlated with LGA ( OR = 2. 10，95% CI : 1. 16 －3. 81) ．@*Conclusion @#Sleep duration＜7 h in the first trimester of preg- nancy is a risk factor for SGA and LGA，and snoring may enhance the association between sleep duration＜7 h in the first trimester of pregnancy and SGA．Pregnant women should keep adequate nocturnal sleep duration to reduce the risk of abnormal neonatal weight.

CT Findings of Unusual Closed Retroperitoneal Trauma / 实用放射学杂志

Objective To analyse CT diagnosis of unusual closed retroperitoneal trauma so that to improve its diagnostic accuracy.Methods CT features of unusual closed retroperitoneal trauma confirmed by clinical data and surgery in 13 cases were analyzed.Results There were adrenal hematomas in 11 cases,among them,2 cases accompanied with renal arterial occlusion,appeared as renal arterial ruptured suddenly and "interface sign".The hematomas appeared as round,similar round or mass hyperdense shadows and in combination with periadrenal tissue injury;pancreatic rupture in 2 cases,appeared as linear area of low attenuation inside pancreas.Conclusion CT scan is an effective modality for diagnosing the unusual closed retroperitoneal trauma.Correct CT diagnosis is very important for the effective surgical treatment as well as reduction of severe complications and mortality of unusual closed retroperitoneal trauma.
