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 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.

AIM: Studies reveal that, cytokines play an important role in the process of various inflammatory reaction, wound repair and cell mutation, also, cytokines are expected to be a novel indicator of ratiocinating wound time. This study was designed to explore the changes in gene expression of interlukin-1? (IL-1?) and interlukin-1? (IL-1?) during the skin wound healing process in mice at different phases. METHODS: The experiment was carried out in the laboratory of Forensic Medicine Department of China Criminal Police University from March 2006 to December 2007. ①Thirty-five BALB/c inbred male white mice of cleaning grade, aged 25-27 g, were used in this study. ②Skin wound model was induced by injuries in the area of 1.0 cm away from two sides of spinal column, without affection on muscles. Three pairs of injuries were established in each mouse. Five animals were decapitated under anesthesia at 0, 3, 6, 12 hours and 1, 3, 6 days, respectively, whereas those at 0 hour were taken as controls. ③The white blood cells at different phases were observed under microscope after immunochemical staining. Real-time quantitative polymerase chain reaction method was applied to detect gene expression of IL-1? and IL-1?. RESULTS: Thirty-five BALB-c inbred male white mice were all involved in the result analysis. ①Skin wound was weakly positive during 0-5 hours after injury; the positive reaction was attenuated during 6-24 hours, and positive cells increased, of which macrophages were dominant. Infiltration of massive leucocyte neutrophils and a small quantity of mononuclear cells were detectable at 1 day; mononuclear cells increased during 2-4 days, and reached a peak at 3 days. In control group, the epidermis, folliculus pili, glandulae sebaceae and coil gland were all weakly positive. ②IL-1? and IL-1? were expressed at early phase after injury, and two expressing peaks were found at 6 and 72 hours, then decreased to normalized levels at 6 days after injury. CONCLUSION: Genet expression of IL-1? and IL-1? in damaged tissues has a regularity with wound time, and can be used for reference to estimate early injury age in forensic cases.

Objective To evaluate surgical management of ruptured abdominal aortic aneurysm (RAAA).Methods Clinical data of 36 RAAA patients undergoing emergent graft replacement or endovascular aortic repair (EVAR) from May 2002 to July 2013 were retrospectively analyzed.25 and 21 patients were associated with hypertension and chronic obstructive pulmonary disease respectively.33 patients were treated with graft replacement.3 patients received endovascular treatment and 1 patient converted to open surgery.Results Perioperative death occurred in 3 patients including severe hemorrhagic shock in 1 patient,cardiac arrest in 1 patient and multiple organ failure in 1 patient.During follow up for 3 to 61 months,no operation related complication,such as artificial graft infection happened.Conclusions Emergent operation including open surgery and EVAR is crucial for RAAA treatment.Early diagnosis,excellent operative techniques and effective perioperative management are measures conducive to lowering the mortality rate of RAAA.

Leber congenital amaurosis (LCA) is one of the main inherited retinal diseases causing congenital blindness.LCA is also characterized by genetic heterogeneity and variable clinical phenotypes.Recent years,a lot of molecular genetic studies related with its pathogenesis have been performed.So far,20 causative genes have been identified that account for LCA.Some correlations between genotype and clinical phenotype have also been found.Those specific clinical manifestations may help to identify the mutant gene that causes the LCA.This review summarized the causal genes,their roles in the pathogenesis of LCA,coupled with relationship between specific gene and Corresponding phenotype,which will assist the clinician in patient diagnosis and counseling.

Objective To investigate the clinic significance of serum carbohydrate antigen ( CA)125 for cirrhosis. Methods 88 patients with type B posthepatitic cirrhosis (male 46,female 24,average age 45?24 years) were divided into three group (A stage35,B stage 28,C stage 25) according to Child-pugh integration. 36 healthy persons as normal controls were studied(male 20,female 16,average age 42?22 years). Serum CA125 was measured by ELISA. We investigated the alteration of serum CA125 with hepatic functional classification. Results The levels of serum CA125 in cirrhosis patients were markedly higher than those in control subjects(P
