RESUMO
Objective:To explore the correlation between ascending aortic elasticity and coronary blood flow reserve (CFR)in patients with hypertension.Methods:A total of 60 patients with essential hypertension were regarded as hypertension group,another 50 normotensive subjects were enrolled as normal control group during the same period. Ascending aortic dilation (D),stiffness (β)and CFR were measured and calculated by tissue Doppler ultrasound,then compared between two groups.Pearson correlation analysis was used to analyze the correlation amongβ,D and CFR.Results:Compared with normal control group,there were significant reductions in D [(3.59±0.30)10-6 cm2/d vs.(2.88±0.77)10-6 cm2/d]and CFR [(3.23±1.16)vs.(2.02±0.63)],and significant rise inβ[(3.54 ±1.52)vs.(5.46±1.98)]in hypertension group,P<0.05 or<0.01. Pearson correlation analysis indicated thatβwas significant inversely correlated with CFR (r=-0.413,P=0.005),while D was significant positively correla- ted with CFR (r=0.384,P=0.003 ).Conclusion:Reduced ascending aortic elasticity is significantly correlated with coronary blood flow reserve.
RESUMO
Objective To investigate manifestations of chronic obstructive parotitis (COP) under sialoendoscope and to evaluate curative effects of duct dilatation and drug perfusion for COP. Methods Twelve patients with COP were examined by sialoendoscopy. Treatment was performed by duct dilatation and gentamycin perfusion one week later. Results There were 11 cases of sialodochitis (complicated by sialostenosis in 7 cases, including 4 cases of polyps and 2 cases of mucus embolism, and simple sialodochitis in 4 cases) and 1 case of simple sialostenosis. Follow-up for 4 weeks showed that results were excellent in 4 cases, good in 7 cases, and poor in 1 case. Conclusions Sialoendoscopic exploration with dilatation procedure and drug perfusion offers certain short-term curative effects in the management of COP.
