Objective: To evaluate the effect of glucocorticoid on the treatment of acute cerebral stroke. Methods: Seventy-six patients with acute cerebral infarction were randomly divided into two treatment groups which included the group of intravenous infusion with dexamethasone 10 mg, Xuesaitong 0.4 g, and sodium citicoline 0.5 g Qd,and the group without dexamethasone treatment. Results: The infarction area enlarged on CT scan and the deficits of neural function accelerated in dexamethasone group. There was no change on CT scan and no neural function deterioration in patients without dexamethasone treatment. Conclusion:Side effect is obtained with the early use of dexamethasone for the treatment of acute ischemic cerebral stroke.

Objective To investigate the possible risk factors for the progression of abdominal aortic calcification (AAC) in MHD patients.Methods Total of 170 patients on MHD between June 2014 and October 2014 in the dialysis center of the Second Hospital of Tianjin Medical University were included prospectively.Lateral lumbar radiography were applied to evaluate patients' AAC score (AACs) at baseline and after two-years of follow-up respectively.According to the change of AACs,the patients were divided into rapid AAC progression group and non-rapid AAC progression group.Multivariable Logistic regression models were used to determine the risk factors for the progression of AAC in MHD patients.Results At baseline,the presence of AAC (AACs≥1) was 43.5％(74/170).The mean follow-up duration was 27.6(24.7,28.0) months.AACs were available in 111 patients,and the presence of AAC was 78.4％(87/111).During the follow up,36 patients developed new AAC;rapid AAC progression was seen in 54 patients,and non-rapid AAC progression was seen in 57 patients.Multivariate Logistic regression analysis demonstrated that hyperphosphatemia (OR=4.373,95％ CI 1.562-7.246,P=0.005) and high density lipoprotein (HDL) (OR=0.031,95％CI 0.003-0.338,P=0.004) were independent risk factors for AAC progression in MHD patients.Conclusions Hyperphosphatemia and low HDL may promote the progression of AAC.Well-controlled serum phosphate and lipid metabolism may slow the progression of vascular calcification,reducing cardiovascular morbidity and mortality.
