ABSTRACT
Twenty-seven patients with subclinical hyperthyroidism(SH)complicated by paroxysmal atrial fibrillation(PAF)were treated with methimazole plus bisoprolol.All patients were examined by Doppler echocardiogram and 24 h ambulatory electrocardiograms before and 3 months after treatment.Serum FT3,FT4,and TSH levels were measured with RIA.The results showed that low-dose methimazole therapy could improve the left ventricular diastolic function(P < 0.01)and help maintain sinus rhythm.The incidence of subclinical hypothyroidism was low.Low-dose methimazole was effective and safe in patients with SH complicated by PAF.
ABSTRACT
This paper analyzes the routine failures and operating flow of full-functional DR-EIDOS3000 and points out the design deficiencies of the detector stand,the elevating table and the console.At last,some countermeasures are suggested for the hidden trouble.
ABSTRACT
Radioactive Protective aprons are used to reduce radiation dose during fluoroscopy and exposure.Tears,cracks and holes can be detected by X-ray inspection.By establishing the rejection criteria,routine inspection and renew,the radioactive safety can be acheieved.
