Graves' disease,the most common disorder of hyperthyroidism,is an autoimmune disease related with autoantibody (TRAb),with the specific mechanism remaining incompletely understood.The therapies for Graves disease include three conventional methods:anti-thyroid drugs,radioiodine and surgery.Only treatment with anti-thyroid drugs is aimed at the immune factor;they can eliminate TRAb and lead to recovery ultimately.Literatures have drumed in that treatment with anti-thyroid drugs was a basic therapy for Graves' diseases,and they were the first choice to cure hyperthyroidism all over the world (except for the U.S.A).The drugs do not destroy the structure of thyroid follicle,and are safe and efficient;moreover,their effect is reversible and therefore do not cause permanent damage to the thyroid.Anti-thyroid drugs not only can be used alone,it also can be used before radioiodine or surgery.ATA chairman professor Cooper(NEJM,2005) propounded a therapy path for Graves' disease,which is helpful for clinical practice.

Objective: To measure the convergence angles of teeth in different teeth positions and different denture designs.Methods:Mesio-distal widths and labio-lingual widths were measured on 226 teeth according to three points in a line on three surfaces (gingival, middle and incise) of each tooth.The distance between every point and the counterpart point in the adjacent surface was measured.Then convergence angles were calculated. Results:The means of the angles were 4.13°±0.77°,4.14°±0.76°, 4.46°±0.95°, 4.76°±0.84° on the first and second premolar, the first and second molar,respectively . There were significant differences between the premolars and molars(P<0.05).On the dentures with the designs of monocrown, triunit-bridge and long bridge the means of the angles were 3.78°±0.74°,4.69°±0.75° and 5.08°±0.85° respectively,the angle on the denture with the design of monocrown was smaller than that of bridge (P<0.05).Conclusion:The convergence angles are different according to different teeth positions and different denture designs, so they should be adjusted according to the clinical requirements.

OBJECTIVE: To recognize the research status on the mechanism of reactive oxygen species (ROS) and NADPH oxidases in cell growth and death,and explore the effects of ROS and NADPH oxidases on cardiomyocyte differentiation.DATA SOURCES: A computer-based online search of Medline was undertaken for the articles about the action mechanism of reactive oxygen and NADPH oxidases in cell growth and death published in English between January 1997 and December 2003 with the key words of "Reactive oxygen species, NADPH oxidase, Cardiomyocytes, Differentiation, Signal transduction".STUDY SELECTION: Inclusive criteria: ①Articles on ROS production and structure and activation of NADPH oxidase and their action mechanism in cell growth and death; ②Research about the molecule mechanism of cardiomyocytes differentiation. The repetitive research and review articles were excluded.DATA EXTRACTION: Totally 132 articles about the action mechanism of ROS and NADPH oxidase and cardiomyocytes differentiation were collected, and 78 ones met the inclusive criteria.DATA SYNTHESIS: ①ROS involved in pathogenesis of many diseases were mainly from intramitochondrial electron transport chains, and NADPH oxidase was closely related with ROS production; NADPH oxidase firstly found in phagocyte was a kind of multienzyme complex, and its activity was regulated by the concentration of Ca2+ in cells and mRNA expression of its subunits. ②At present, many researchers presumed that oxidative stress was a double-edged sword, and it two-ways regulated the cell proliferation and death, in which ROS served as the second messenger in the signal transduction. Recent data showed that ROS and NADPH oxidase played important roles in cardiomyocytes differentiation; however, it was not identified which subunit of NADPH oxidase expressed in myocardial cells and its detail regulative pathway. Those problems were important for further study in the molecule mechanism of cardiomyocytes differentiation.CONCLUSION: ROS including superoxide anion (O2-), hydrogen peroxide (H2O2) and hydroxyl radical (OH-), are generated in cardiomyocytes mainly by a membrane-bound NADPH oxidase (NOX). The NOX-derived ROS, as the second passenger, play important roles in various intracellular signaling pathways. In cardiomyocytes, ROS have the potential to alter the balance between cell growth and death through these signaling pathways. Recently,ROS have been demonstrated to play a critical role in regulation of cardiomyocyte differentiation from embryonic stem cells. Research in the regulation mechanisms of ROS will contribute to our better understanding of he role of ROS and NADPH oxidase in cardicomyocyte differentiation and will lead to the identification of factors able to promote cardiac differentiation.

Objective The study is to investigate the effect of tanshinone on lung reperfusion injury. Methods 24 New-Zealand rabbits were randomly divided into two groups. In one group, the lungs were perfused and preserved with LPD solution, the other with LPD+ tanshinone solution. The isolated lungs were preserved for 18 hours and then reperfused with rewarming whole blood. After reperfusing 30 minutes the lung samples were examined by pathology, wet/dry weight and measure of NO, SOD and MDA. Results In two groups, the reperfusion injury lungs were fresh, but had partial congestion, edema and ecchymoma under naked eye, under light microscopy the structures of the pulmonary vesiculars, branchia and capillaries were complete, but the epithelial cells of the vesicles and capillaries in the LPD group were more swelling and hypertrophy than that in LPD+ tanshinone group. The wet/dry weight ratio was significantly lower in LPD+ tanshinone group than in the LPD group. NO [(2.16±2.15)μmol/g] and SOD [(37.03±18.01NU/mg] were higher in the LPD+ tanshinone group than in the LPD group [(0.68±0.33) μmol/g, (17.63±11.04)NU/mg] (all P<0.05), MDA was lower in the LPD+ tanshinone group [(0.47±0.20)μmol/mg] than in the LPD group [(0.86±0.44)μmol/mg] (P<0.05). Conclusions Tanshinone can dean oxygen free radical and is of stronger antioxidation, results in alleriating of lung reperfusing injury. Tanshinone has positive effect on preservative quality of the reperfusion injury lung.
