OBJECTIVETo explore the effect of glimepiride on the glucose uptake as well as glucose transporter (GLUT)-1 and GLUT-3 expression levels of rat mandibular osteoblasts in hyperglycemia.

METHODSPrimary osteoblasts were isolated and cultured. Then, the cells were placed in an osteogenic medium containing two glucose concentrations (5.5 and 16.5 mmol X L(-1)), with or without glimepiride (10 micromol x L(-1)). Glucose uptake was determined by employing 18F-deoxyglucose (18F-FDG) in the cells, and GLUT-1 and GLUT-3 expression levels were evaluated by Western blot analysis.

RESULTSGlucose at 16.5 mmol x L(-1) significantly inhibited 18F-FDG uptake and downregulated GLUT-3 protein expression in osteoblasts. Hyperglycemia increased GLUT-1 protein expression. Glimepiride significantly increased glucose uptake and upregulated GLUT-1 and GLUT-3.

CONCLUSIONGlimepiride enhance the glucose transporter in rat osteoblasts at two different glucose concentrations.

Objective To investigate the effect of Beraprost Sodium and atorvastatin in the treatment of TIA combined carotid plaques. Method 60 cases in our hospital with TIA and carotid artery plaques were randomly divided into observation group and control group, 30 cases in each group. The observation group was received beraprost natriuretic peptide and atorvastatin calcium therapy, the control group was treated with atorvastatin calcium. 12 months later,two groups were compared with carotid plaque area change and coagulation conditions. Results Carotid plaque area in observed group was significantly less than the control group (P<0.05). The differences of platelet agglutination test(PAgT), fibrinogen(Fg) , hypersensieive 3 C-reaction protein, total cholesterol(TC), high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol (LDL), TIA recurrence rate and incidence of ischemic stroke between two groups after treatment were statistically significant (P<0.05). Conclusion Beraprost Sodium and atorvastatin has a good effect in reducing carotid plaques area, adjusting blood fat and preventing TIA and ischemic stroke, It is worthy to clinical popularization and application.

Objective To investigate the related risk factors of old cerebral infarction patient.Methods Tbe related data of 248 old male patients(>65)who weared the 24-h ambulatory blood pressure monitoring at our depanment from September of 2007 to December of 2007 were retrospectively analyzed.They were divided into two groups according to WHO diagnostic criteria for cerebral infarction:cerebral infarction group(n=58)and non-cere-bral infarction group(n=147).The correlation between related risk factors with cerebral infarction were further stud-ied.Results①The result of multiple factor logistic regression analysis(α=0.05,β=0.01 is the selected criteri-on) showed:cerebral Lacunar infarction and the level of blood uric acid had the significant impact on the occurrence of cerebral infarction.To compare with non-cerebral lacunar infarction,the relative risk of cerebral infarction morbili-ty was 7.443 in cerebral lacunar infarction.The level of blood uric acid decreasing l μmol/L,the relative risk of cer-ebral infarction morbility increased 0.994.②Every ingredient of blood pressure deploy independent-samples T test showed that the highest value of systolic blood pressure(167.12±22.08)and the highest value of pulse pressure (88.03±20.81)raised up obviously compared with non-cerebral infarction group.Conclusion In old male,the incidence rate of cerebral infarction is predominantly correlated with cerebral lacunar infarction and the level of blood uric acid,and is closely correlated with the highest value of systolic blood pressure and the higheat value of pulse pressure in all the ingredients of blood pressure.

Objective To investigate the clinical significance of the levels of D-dimer and hs-CRP in the elderly patients with coronary disease. Methods One hundred and twenty-two patients with coronary disease were divided into four groups according to their clinical manifestations, there were old myocardial infarction group ( OMI, n =27 ) , stable angina pectoris group ( SAP, n = 29), acute coronary syndromes group ( ACS, n = 32) and old myocardial infarction with acute cardiovascular syndrome group (OMI + ACS,n =34). The control group included the patients without coronary disease (n =30). The patients who had infection, malignant tumors, liver and kidney dysfunction, cerebral infarction, venous embolism in lower extremities and pulmonary embolism were not included, and the patients enrolled should not be on medication of antiplatelet drugs, anticoagulants and antibiotics within the last two weeks. The levels of D-dimer and hs-CRP in all groups were determined by immunoturbidimetric assay and immune scattering assay respectively. Results In each comparison between two groups, the level of D-dimer has no significant difference between the OMI and the SAP ( P > 0. 05 ) , ACS and the OMI + ACS ( P > 0. 05 ) ; but significant difference between the OMI and the control groups ( P < 0. 05) and more significant difference between the other groups were found (P < 0. 01). As for the level of hs-CRP, there was no significant difference between the OMI and the SAP groups (P > 0. 05) or between the ACS and the OMI + ACS groups (P > 0. 05); but significant difference between the other groups (P < 0. 01). the positive relationship between the levels of D-dimer and hs-CRP have in coronary disease in the elderly patients was also found(r = 0. 81 ,P <0.01). Conclusions D-dimer and hs-CRP can be used as the clinical makers to predict the occurrence of the coronary disease in the elderly patients. D-dimer and hs-CRP can be used as the clinical makers to determine the stability of cardiovascular atherosclerotic plaque and the risk of acute cardiovascular syndrome occurrence. They can also be used as the clinical makers to predict the recurrence of the acute cardiovascular syndrome in the patients with old myocardial infarction. However, they can not be used to determine whether the patients with acute cardiovascular syndrome had old myocardial infarction already or not. The levels of D - dimer and hs - CRP are closely related in coronary disease in the elderly patients.

【Objective】 To develop an assay to determine β-lactam antibiotics using microcolumn gels and to study the β-lactam antibiotics present in the blood of patients and their clinical significances. 【Methods】 446 patients with a history of taking β-lactam antibiotics from January 2019 to June 2019 were randomly selected from Trauma Emergency Center, Department of Arthrosis, Department of Spine and Department of Bone Oncology of our hospital, and 4 mL(per capita) venous blood was collected. Irregular antibody screening, anti-globulin detection and drug antibody determination were performed by microcolumn gel method. The data of gender, age, disease, blood transfusion history and medication were collected. The test results and clinical data were retrospective analyzed. 【Results】 The yielding rate of antibody was 0.45%(2/446) in patients with a history of taking β -lactam antibiotics. 16.38%(73/446) of the samples were positive in direct antiglobulin test, and 64.38%(47/73) of them did not agglutinate with RBCs treated with drugs. The yielding rate of specific antibodies against drug was 4.93%(22/446), and the titer ranged from 2 to 128(8). 1 case of auto-IgM antibody, 1 case of blood group related antibody and 2 cases of non-specific protein adsorption were detected. The yielding rate of drug antibody in patients with blood transfusion history reached to 12.10 %(22/124), so it was also high in patients with bone tumor. 【Conclusion】 Direct antiglobulin assay is helpful for the detection of β-lactam antibodies. The negative results of antibody screening cannot completely exclude the presence of drug antibodies. The yielding rate of drug antibody can be greatly improved by specific drug antibody detection, and it was higher in transfused patients relative to non-transfused one.
