Objective To establish a mathematical model to describe the skeletal class Ⅲ malocclusion of patient dental and basal bone arch form, for providing a data reference and basis for further study. Methods Thirty-five patients with skeletal classⅢmalocclusion were selected in this study for computed tomography CBCT. The data of 3-D image were analyzed, and dental arch marker (Fa) and base bone arch marker (Ba) were determined. The reference plane was determined by least square method. Software Matlab 7.0 was used to calculate two-dimensional coordinate system. Based on this, a mathematical model was established to describe the dental and basal bone arch form and then to validate the mathematical model. Results (1) The mathematical model can be used to describe the dental arch form of skeletal classⅢmalocclusion, maxillary:Y=46.12 [1-(2X/70.99)2]1.052;mandibular:Y=39.16 [1-(2X/64.51)2]1.038. (2) The mathematical model can be used to describe the basal bone arch form of skeletal classⅢmalocclusion, maxillary:Y=43.14 [1-(2X/75.09)2]1.061;mandibular:Y=39.03 [1-(2X/60.63)2]1.021. (3) Fa was located at Ba labial side in the maxilla, the distance was positive. Fa was located at Ba lingual side in the mandibular, and the distance was negative. (4) The fitting correlation coefficient of beta-function curve and each tooth on the dental and basal bone arch of skeletal class Ⅲ malocclusion were greater than 0.7 (P<0.05). Conclusion In this study, the mathematical model can be used to describe the dental and basal bone arch form of the skeletal classⅢmalocclusion, which can guide further research.

Objective To investigate the effect of Danzhijiangtang capsule on serum,fat in type 2 diabetic rats.Methods The model of type 2 diabetes mellitus rats were established by injecting small does streptozotocin(STZ)into abdomen and feeding high sucrose-fat diet.All the rats were divided randomly into five groups.The level of blood glucose,serum insulin,insulin sensitivity index,blood fat(triglyceride, cholesterol,high-density lipoprotein,low-density lipoprotein),free fatty acid after treated were examined. Results Danzhijiangtang capsule could decrease the level of blood fat.Conclusion Danzhijiangtang capsule could improve the blood fat in type 2 diabetic rats.

AIM: To study the expression of nuclear factor kappa B (NF-?B) in the L 1-L 4 spinal ganglions of adjuvant arthritis (AA) rats, to explore the neuroendocrinoimmunological mechanism of rheumatoid arthritis (RA). METHODS: The expression of the NF-?B protein was detected by immunohistochemistry method and the alteration of the active NF-?B protein (nuclear protein) was investigated by Western blotting analysis. RESULTS: The expression of NF-?B protein in L 1-L 4 spinal ganglions of AA rats was much higher than that in the healthy controls ( P
