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 study the standards and safety of low intensity warfarin anticoagulation therapy in elderly patients after heart valve replacement.Methods Three hundred and fifty-six patients (203 males and 153 females) aged 60-73 (64.3±5.1) years who underwent heart valve replacement in our hospital from January 2004 to June 2014 were divided into aorta valve replacement (AVR) group (n =101),mitral valve replacement (MVR) gro up (n =164),and combined AV and MV replacement group (DVR,n =91) according to their surgical procedure,and further divided into INR ＜1.6 group (n=19),1.6≤INR≤2.5 group (n=299),and INR＞2.5 group (n=38)according to their INR.The INR and incidence of thrombosis and hemorrhage were recorded during the follow-up period.Results Thrombosis occured in 5 patients (1.4％),hemorrhage was found in 49 patients (13.8％),the INR was 1.6-2.5 in the patients included in this study.No significant difference was found in the incidence of hemorrhage in AVR,MVR and DVR groups.The incidence of hemorrhage was significantly different in INR＜1.6 group,1.6≤INR≤2.5 group,and INR＞2.5 group.Conclusion Oral warfarin at the mainteinance dose of 1.6-2.5 can achieve its satisfactory anticoagulant effect in old patients after heart valve replacement.

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.

Objective To evaluate endovascular aortic repair for retrograde Stanford type A aortic dissection with an entry tear in the descending aorta.Methods From April 2006 to Dec 2012,31 patients with retrograde type A aortic dissection were treated with endovascular technique.22 patients had pleural effusion,14 patients had patent false lumen in the ascending aorta.Emergency operation was performed in 2 patients with acute right renal artery and right common iliac artery ischemia respectively.29 patients received endovascular treatment after 3 weeks conservative treatment.Chimney technique was used in 3 patients.Results All procedures were technically successful without severe complications.Ascending aorta recovered 1-3 months after operation.Pleural effusion subsided 3 days to 3 weeks after endovascular treatment.During follow-up of (31 ± 18) months,no severe complications developed,all the stent-grafts placed by chimney technique were patent.Conclusions Endovascular aortic repair can be used in the treatment of retrograde Stanford type A aortic dissection.Chimney technique can be used to reconstruct supra-aortic branches.

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.

Objective To examine the association between baseline body mass index (BMI) and overall survival (OS) in lymph node negative breast cancer patients. Methods From Jan. 1st, 1998 to Dec. 30th, 2008, 662 patients with lymph node negative breast cancer were treated at the Breast Center of Peking University Peo-ple’s Hospital. The clinical factors such as menopause status, tumor stage, body mass index (BMI), total triglyc-eride (TG), total cholesterol (TC) and glucose (GLU) were collected. The chi-square test was used to assess the association between obese and other factors. Log-Rank test and Cox regression analysis were performed to make univariate and multivariate analysis. Results The median follow up was 82 months (ranging from 2 to 209 months). The 5-year and 10-year survival was 93% and 82%. Obesity was associated with GLU and tumor stage (χ2=5.224, P=0.031; χ2=6.007, P=0.14), whereas there was no relationship between obesity and other factors. The Log-Rank test revealed statistically significant better survival for non obesity (χ2=4.693, P=0.030), normal GLU (χ2=4.678, P=0.031) and HR positive patients (χ2=7.837, P=0.005). COX regression analysis showed that BMI (χ2=3.874, P=0.049) and HR status (χ2=6.782, P=0.030) had independent influence on overall survival of node negative breast cancer patients. Conclusion Obesity is an adverse prognostic factor for lymph node negative breast cancer patients, which may be associated with obesity-related disorders such as high blood GLU.

Toll-like receptor( TLR) ,which belongs to pattern recognition receptor,is type I transmem-brane glycoprotein. TLR activates natural immune and induces several cytokines. Foreign studies have showed that bacterial infection is closely related with TLR. In this paper,the relationship between TLR and bacterial in-fection is reviewd.
