RESUMEN
Objective To summarize and analyze characteristics and diagnostic value of ultrasonography in the diagnosis of 46 cases of gynecomastia sonographic image.Methods 46 cases of male breast lumps were tested by high frequency ultrasound probe The mammary glands position,thickness,border,shape,internal echo,the internal flow signals,with or without axillary lymph nodes were observed.Results There were 32 cases of unilateral disease, including 18 cases of left side,14 cases of right side,14 cases of bilateral disease.Sonographic indicated 28 cases of mammary gland tissue echo to see beneath the nipple with low echo,the boundary more clearly,more uniform internal echo;and 12 cases showed glandular tissue thickening,echogenic and showed cord -like,similar to the female gland hyperplasia sonogram;and 6 cases showed patchy irregularly echogenic area.Color Doppler performance was that the 33 cases showed glandular tissue without significant blood flow signals,10 cases showing 1 -2 strip -shaped blood flow to see in the glandular tissue,3 cases showing more abundant flow signals.Conclusion Ultrasonography has no pain,with higher diagnostic yield reproducible operation,so gynecomastia is the preferred method.
RESUMEN
Objective To explore the improve mechanism of the cerebral blood stream state in patients with cervical dizziness(CD) after treatment combined with traction and heating acupuncture.Methods The results of transcranial Doppler(TCD) were compared in 53 patients with CD being treated with traction and heating acupuncture.Results The results showed that in 53 CD cases after treatment the velocity of the blood flow of double middle cerebral arteries,posterior cerebral arteries and right anterior cerebral artery were decreased remarkablely,besides this left anterior cerebral artery.The TCD examined results got near to normal value of contrast group(P
