ABSTRACT
Objective To investigate changes in the intraocular pressure(IOP) and anterior chamber angle in patients with chronic renal failure before and after hemodialysis. Methods Fifty?eight patients(116 eyes) with chronic renal failure were measured with Goldmann applanation tonometer and anterior segment optical coherence tomograph. The patients were divided into three groups based on gonioscopy results:the narrow angle group(22 eyes),the Iris neovascular group(3 eyes)and the open angle group(91 eyes). IOP was measured by Goldmann applanation tonometer in patients in the three groups before and after hemodialysis. Anterior chamber angle opening distance (AOD) was detected by anterior segment optical coherence tomograph before and after hemodialysis. The blood urea nitrogen,creatinine,albumin were also determined before and after hemodialysis. All changes in the parameters were analyzed with a paired t test. Results The IOP in narrow angle eyes and in neovascular eyes increased significantly after hemodialysis ,while the IOP in open angle eyes showed no significant changes. The AOD decreased significantly after hemodialysis. The blood urea nitrogen and creatinine decreased significantly in 58 patients,while albumin increased after hemodialysis. Conclusion The IOP in narrow angle eyes and in neovascular eyes increased after hemodialysis ,correlating with the resistance increase of aqueous outflow pathway and the change of plasma osmotic pressure. As a result ,it is recommended that the condition of eye of patients with chronic renal failure should be checked ,and patients should receive appropriate controlling measure or treatment before hemodialysis.
ABSTRACT
Objective To investigate the curative effect of benidipine hydrochloride on patients with coronary slow flow angina pectoris(CSFA).Methods Sixty cases patients with CSFA were randomly divided into two groups of 30 patients each.In the control group patients were received aspirin(100 mg,1 times/d) and atorvastatin(20 mg,1 times/d) as basic treatment;in the treatment group patients were received basic treatment plus benidipine hydrochloride(4 mg,1 times/d).Follow up for 6 mouths,the effectiveness rate of treatment(relief of angina and electrocardiogram of myocardial ischemia),the correction of thrombolysis in myocardial infarction(TIMI) frame count(CTFC) before and after the different intervention,and the incidence of adverse cardiovascular events were compared between the treatment group and the control group.Results The effectiveness rate of treatment in the treatment group(86.7%,26/30) was significantly higher than that in the control group(63.3%(19/30);χ2=4.356,P=0.037).There were significant reductions of CTFC in both groups after the different intervention(treatment group:(28.43±3.95) frames vs.(18.40±3.73) frames,t=10.254,P=0.000;control group:(27.87±4.14) frames vs.(21.87±4.17) frames,t=5.580,P=0.000).There was more significant reductions of CTFC in the treatment group as compared to the control group(t=2.138,P=0.037).The incidence of adverse cardiovascular events in the treatment group(10.0%(3/30)) was significantly lower than that in the control group(33.3%(10/30),P=0.028).Conclusion Benidipine hydrochloride is effective in the treatment of CSFA.
