Cardiovascular disease (CVD) is one of the major complications of type 2 diabetes mellitus (T2DM), which results in a high risk of mortality. Thus, the cardiovascular safety of new anti-diabetic agents has become an important prob?lem with wide concern. There are two classes of incretine-based medications: glucagon-like peptide-1 receptor agonist (GLP-1RA) and dipeptidyl peptidase-4 (DPP-4) inhibitor (DPP-4I). It has been demonstrated that GLP-1RA and DPP-4I possesse beneficial actions in both animal models of cardiovascular dysfunction and patients with ischemic heart diseases. However, their effects on the cardiovascular system in diabetic patients with heart diseases are still uncertain. Here, we sys?tematically reviewed the effects of GLP-1RA and DPP-4I on cardiovascular system to provide more evidence of incretin-based therapy application for diabetes and complications.

Autoimmune diseases are characterized by the presence of various autoantibodies and may cause injuries to multiple organs,with kidney as the most common and important organ involved.Autoantibodies are of great importance in the diagnosis,treatment and prognosis of autoimmune renal diseases.Lupus nephritis,anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis and antiglomerular basement membrane (GBM) disease are the most common autoimmune renal diseases.Anti-C1q antibody,ANCA and anti-GBM antibody play important roles in those diseases,respectively.Appropriate and steady detecting methods are crucial to clinicians,and the results should also be interpreted with great cautions.

Objective To investigate androgen receptor (AR) expression in triple negative breast cancer(TNBC) patients and its predictive value for clinical outcomes.Methods Five hundred and sixty-eight primary breast cancer patients who received surgery treatment from January 2008 to January 2010 were included in this study.Tissue sections of surgical resection specimens were underwent estrogen receptor (ER),progesterone receptor (PR),and human epidermal growth factor receptor 2 (HER2) immunohisto chemical staining,according to the judgment for triple negative breast cancer and non triple negative breast cancer.Data on age,family history,menstruation,tumor size,tumor stage,tumor grade,pathological type and lymph node metastasis were collected for analysis.Immunohistochemical analysis of AR was done in tissue sections of triple negative breast cancer patients,Kaplan-Meier method was used to compare survival between AR(+) and AR(-) groups,and Log-rank method was used to determine the association between AR-positive expression and 5-year overall survival as well as disease free survival.Results Among 568 breast cancer patients,174 (30.6％)TNBC patients were identified,including 84 patiens with AR (-) expression and 90 patients with AR (+) expression.During 5 years' follow-up,reccurrence rate was 35.7％ (30/84) in AR (-) group and 20.0％ (18/90) in AR(+) group;5-year overall survival rate was 73.8％ in AR(-) group and 81.1％ in AR(+) group.There was no significant association between AR(+) expression and 5-year death or recurrence rate,while after adjusting for age,menstruation,tumor size and lymph node metastasis,AR (+) expression was significantly associated with decreased 5-year death and recurrence rate,adjusted hazard ratio (HR) was 0.794,95CI (0.430-1.021) and 0.722,95CI (0.451-0.965) respectively.Conclusion AR (-) expression is associated with increased risk of death and recurrence and is a promising predictive marker for poor clinical outcomes.

Objective To study and observe the changes of pancreatic blood flow and blood miR indexes of patients with pancreatic cancer.Methods 70 patients with pancreatic cancer were selected as the observation group,70 health persons of the same age at the same period were selected as the control group, then the blood flow indexes and blood miR of observation group’s lesion and tumor adjacent tissue and control group’s healthy pancreas were detected,and the detection results of control group and observation group were compared,then the above indexes of observation group with different Hemrick stages were compared.Results The lesion blood flow indexes of observation group were all obviously worse than those of control group(P<0.05),blood miR indexes were all higher than those of control group(P <0.05),the lesion and tumor adjacent tissue blood flow indexes all had obvious differences(P<0.05),and the above indexes of observation group with different Hemrick stages all had significant differences(P<0.05).Conclusion The pancreatic blood flow and blood miR of patients with pancreatic cancer all show obvious abnormal state,and the differences of indexes of patients with different Hemrick stages are all prominent, so the pancreatic blood flow and blood miR indexes all have higher value for the patients with pancreatic cancer.

Objective To determine the reversal effect of psoralen on multidrug resistance (MDR) in the harringtonine (HT)-resistant leukemic cell line HL60/HT. Method The modulating effect of psoralen on MDR in HL60 and HL60/HT cells were determined by the measurement of cell growth and viability via MTT assay. High performance liquid chromatography(HPLC) was used to analyze intracellular HT concentrations in HL60/HT and HL60 cells treated with psoralen. Result Psoralen from 1 to 20 μmol/L could reduce the value of IC50 to HT and enhance the accumulation of HT in HL60/HT cells. Conclusion Psoralen can reverse MDR of HL60/HT cells and is a potential modulator of MDR.

Objective To study the relationship between serum homocysteine level and acute type 2 diabetes mellitus complicated with cerebral infarction.Methods Patients were divided into three groups:acute diabetic cerebral infarction group including 87 patients,diabetes mellitus including 72 patients and control group including 67 healthy persons.The HCY,folic acid,VitB12 and serum lipid were determined.The data was analyzed and the relationship was discussed.Results The level of HCY in diabetic cerebral infarction group[(15.7 ±9.7)nmol/L]was much higher than that in the other two groups[(11.9±7.2)nmol/L and(13.5±6.1)nmol/L].Conclusion HCY maybe participate in occurrence and development of diabetes and pathological changes of blood vessels.It was an independent risk factor of acute cerebral infarction.

Docetaxel and vinorelbine, which were plant alkaloids, had showed the good activities as chemotherapy of breast cancer. Combination chemotherapy with docetaxel and vinorelbine had drawn more and more attention. This papers reviewed the docetaxel/vinorelbine combination treatment of breast cancer.
