Objective To explore changes of gray matter volume in patients with obsessivecompulsive disorder (OCD) in Chinese Han population using optimized voxel-based morphometry (VBM) ,and investigate its relationship with clinical symptoms. Methods Twenty patients with OCD and 20 age,sex and handedness matched healthy controls were scanned using 3D-T1 images on a 3.0 T MR system. The high resolution T1WI was preprocessed according to the optimized VBM protocol in Statistical Parametric Mapping (SPM5). Two-sample t test was performed to characterize the differences of the gray matter volume (GMV) between the OCD patients and healthy controls, and the correlations between the GMV and symptom severity and cumulative illness duration were examined using Pearson correlation in SPSS 16. 0, respectively.Results Compared to controls, OCD patients demonstrated increased GMV in left thalamus, right thalamus and left cerebellum after false discovery rate (FDR) correction. No areas of significantly decreased GMV was observed in OCD patients in relative to healthy controls. The mean eigenvalue ranged from 0. 5782 to 0. 889 representing the left thalamus volume of OCD patients was 0. 6813 ± 0. 0718, and that ranged from 0. 5546 to 0. 9062 was 0. 6869 ± 0. 0808 tor right thalamus. The mean eigenvalues were positively correlated in bilateral thalamus (r = 0. 94, P < 0. 01). Conclusion Using optimized VBM, the current research indicates that the pathophysiology of OCD is associated with GMV abnormalities not only in corticostriato-thalamo-cortical (CSTC) circuit, but also in the cerebellum.

BACKGROUND:The carriers made from biodegradable and biocompatible polymeric materials represent an exciting approach to increase the bioavailability and stability of oral y administered insulin by the chemical reaction or physical encapsulation of insulin.
OBJECTIVE:To mainly review the research progress of the material types, preparation methods, physicochemical characteristics, in vitro release kinetics, and bioavailability of polymeric materials adopted as oral insulin carriers.
METHODS:The first author searched PubMed, Elsevier and CNKI databases for articles (2002-01/2013-02) concerning the polymeric materials and oral insulin carriers with the key words of“polymeric biomaterials, oral insulin, carrier”in English and in Chinese.
RESULTS AND CONCLUSION:Currently, there are mainly two kinds of polymeric biomaterials used for oral insulin delivery systems, that is, natural polymeric biomaterials (such as chitosan and alginates) and synthetic polymeric biomaterials. The most commonly used synthetic polymeric materials for the preparation of these vehicles are polyesters, polyacrylates and their copolymers, which are wel known for their good biodegradability, biocompatibility, and physiological properties. Although researchers have tried to develop promptly oral insulin formulation using various technologies, the reports about clinical application or commercial success have not been seen because of several questions such as polymer material as a carrier, the lower bioavailability of insulin, the quality standards and stability of the formulation. Hence, future studies wil focus on the development of a new type of polymer-based material as carriers by choosing the new materials or modifying physical and chemical characteristics of existing polymers, to avoid gastrointestinal destruction of the insulin and increase bioavailability of insulin in the body, so as to obtain the good control ed release rate and effect.
