ABSTRACT
Objective To study the correlation between TCM constitutions and sleep quality in the elderly population in Hunan Province; To provide a basis for improving sleep quality and adjusting the unbalanced constitutions of the elderly. Methods Multi-stage stratified sampling combined with convenient sampling method was used. TCM constitution rating scale, Pittsburgh sleep quality index, and self-designed general demographic, health and lifestyle questionnaire were used to conduct cross-sectional survey of elderly people living in Hunan Province. Results PSQI scores were negatively correlated with the balanced constitution, and positively correlated with unbalanced constitution, and sleep disturbance was closely related to yang deficiency and qi deficiency. The damp heat, phlegm-dampness, blood stasis, yin deficiency and qi deficiency got the highest scores in the five factors of sleep latency, sleep duration, sleep efficiency, sleep disorders and daytime dysfunction respectively. Conclusion Sleep problems of the elderly in Hunan Province are more prominent, and constitutions and sleep quality affect each other. Different TCM constitutions of sleep disorders in the elderly are different, and should be adjusted according to the constitutions.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the application of MS-CT and 3D reconstruction in diagnosis and treatment of vascular malformations in head and neck.</p><p><b>METHODS</b>20 cases with vascular malformations in head and neck underwent MS-CT and 3-D reconstruction. Then the treatment was determined based on the results of MSCT scanning. The postoperative results were evaluated.</p><p><b>RESULTS</b>The images of MS-CT showed the edge of vascular malformations partially or completely in 16 cases of venous malformations. The lesion's anatomic site and 3-D position was obtained. The 3-D images also showed the overexpanded supply arteries in 4 case of arteriovenous malformations. 2 case of venous malformations in lip underwent resection and healed completely. 12 cases of venous malformations in buccal and floor of mouth were treated with compartmentalized sclerotherapy with partial lesion involution. 2 case of venous malformations in mouth floor were treated with operation followed by sclerotherpy with partial lesion involution. 4 cases of arteriovenous malformations were treated with Superselective Artery Embolization with partial lesion involution.</p><p><b>CONCLUSION</b>MS-CT and 3D reconstruction can play an important role in diagnosis and treatment of vascular malformations in head and neck.</p>

<p><b>OBJECTIVE</b>To evaluate the diagnostic value of multi-slice spiral CT (MSCT) three dimensional (3D) reconstruction for maxillofacial diseases.</p><p><b>METHODS</b>Sixty patients with maxillofacial diseases underwent the scanning of MSCT with 3D reconstruction. Among them, 34 patients with maxillofacial fracture, 10 patients with maxillofacial tumors and tumor-like diseases, and 16 patients with congenital deformities. The MSCT scanned with slice thickness of 2 mm. The methods of 3D reconstruction included multi-planar reconstruction (MPR), shaded surface display (SSD), and volume rendering (VR). The results were compared with what was observed during operations.</p><p><b>RESULTS</b>Totally 36 cases of maxillofacial fracture were shown by 2D or 3D imaging and were validated by the observations during operation. The MSCT with 3D reconstruction imaging was significantly superior to 2D axial imaging in maxillofacial fracture. Three dimensional imaging could clearly show the spacial anatomy of facial, fragment displacement, and tracing fracture lines. However, 2D imaging had better effectiveness than 3D imaging in observing deep structure and fine fracture. In maxillofacial tumors and tumor-like diseases, 3D imaging was significantly superior to 2D axial imaging in showing the tumor shape and spacial relationships between tumors and surrounding structures. Two dimensional imaging and MPR imaging were excellent to reveal internal structure and pathological changes of tumors. 2D imaging and MPR imaging also achieved better results in showing tumors extended to soft tissues. In maxillofacial congenital deformities, 3D imaging were superior than 2D imaging.</p><p><b>CONCLUSION</b>3D imaging has an important value in the diagnosis and clinical assessment of maxillofacial fracture, tumor-like diseases, and congenital deformities.</p>
