Résumé
Objective:To conduct a scoping review of health behavior-related assessment tools for pregnant women with gestational diabetes mellitus (GDM).Methods:A total of 6 Chinese and English databases, including CNKI, Wanfang Database, China Biomedical Literature Database, PubMed, Web of Science Core set and Embase, were systematically searched by the terms of “gestational diabetes mellitus”，“health behavior”，“assessment”. The relevant contents of GDM health behavior-related assessment tools were retrieved for systematic analysis, and the results were normalized reported. The search period was from the establishment of the databases to February 1, 2023.Results:A total of 2 657 literatures were retrieved, and 41 literatures were finally included after screening, including 16 literatures on the development and verification of assessment tools, 2 literatures on localization of assessment tools, and 23 literatures on the application of the assessment tools. A comprehensive analysis was conducted on 18 assessment tools, including 16 original assessment tools and 2 localized assessment tools, spanning the years 1987 to 2020. The assessment content covered dietary behavior, physical activity behavior, medication adherence, blood glucose monitoring behavior, treatment adherence, self-management behavior, and health-promoting lifestyles. Among them, 7 assessment tools were validated for reliability and/or validity in pregnant women with GDM. Among the 23 studies that covered the implication of the assessment tools, the Pregnancy Physical Activity Questionnaire and Health-Promoting Lifestyle Ⅱ were the most commonly utilized tools for assessing health behaviors in pregnant women with GDM.Conclusions:There is a wide variety of assessment tools related to health behaviors in pregnant women with GDM, and the assessment content is relatively rich. However, most of the assessment tools have not been validated for their reliability and validity within the GDM population, limiting their clinical application and promotion.

Objective To explore the diagnostic value of dual syringe and dual-channel direct multi-slice computed tomography venography(MSCTV) for lower extremity deep venous obstructive disease.Methods 100 patients highly suspected deep vein thrombosis by clinic wereunderwent dual syringe and dual-channel direct MSCTV.The original data processed with technology of subtraction,and put into workstation and reconstructed with maximum intensity projection(MIP),multiplanar reformation(MPR) and volume rendering (VR).Images of deep venous obstructive lesions were analysed and graded.All patients were underwent DSA in one week.Results Direct MSCTV showed that the reconstructed images and the vascular contrast were very clear.In the evaluation of deep venous,excellent proportion was 95 ％ for the inferior vena cava,94 ％ for the common iliac vein,95 ％ for the external iliac vein,95.5 ％ for the femoral vein,96.5％ for the popliteal vein and 92 ％ for the low leg vein.Direct MSCTV displayed complete and regular vein in 8 normal patients,92 cases displayed different parts and different degrees of thrombosis.On original axial images,eccentric filling defect of vascular were showed (there were 64 multiple vein occlusion cases and 28 solitary obstruction cases).The occlusion locations in deep venous were as following:3 in the inferior vena cava,67 in the common iliac vein,28 in the external iliac vein,50 in the femoral vein,26 in the popliteal vein,89 in the anterior tibial vein,35 in the posterior tibial vein and 5 in the peroneal vein.There were 7 normal patients and 93 patients with different parts and different degrees of thrombosis.Conclusion Direct MSCTV can accurately show deep vein thrombosis,which image is clear and reliable for displaying the scope and extent of lesions of the vascular and whether the collateral circulation established.Direct MSCTV has a significant clinical value in diagnosing the thrombotic disease of deep vein obstructive lesions.

OBJECTIVE@#The utility of virtual endoscopy is compared to fiberoptic endoscopy and was also investigated with respect to accuracy of diagnosis and reproduction of images in patients with obstructive sleep apnea hypopnea syndrome (OSAHS).@*METHOD@#Twenty-one patients with OSAHS were examined by helical spiral CT axial images and fiberoptic endoscopy. The helical spiral CT axial data was reconstructed using a VE software program. The results were compared to the fiberoptic endoscopic findings done by the otolaryngologists. All the patients were examined both in the sleeping and nonsleeping status. The dimensions of soft palate, uvula, lingua and epiglottis region were evaluated.@*RESULT@#The results both in the virtual endoscopy evaluation and fiberoptic endoscopy was statistically significant difference in all of region. In the palate region, there was statistically significant difference in the left-and-right dimension, but no difference in the fore-and-aft dimension both in the sleeping and nonsleeping status.@*CONCLUSION@#The dimensions of upper airway were more difference between in the sleeping and nonsleeping status. The change of dimension was more in the left-and-right; the fiberoptic endoscopy has more diagnostic significance in evaluation of dynamic movement of the upper airway; virtual endoscopy evaluation of the upper airway was accurate in assessing stenosis width and length; virtual endoscopy added more information about anatomic structure and pathological change of the upper airway.
