Purpose To evaluate the left ventricular regional diastolic function in coronary heart disease (CHD) patients without regional wall motion abnormality by real-time three-dimensional speckle tracking imaging (RT3D-STI) to investigate the value of RT3D-STI in the diagnosis of early CHD. Materials and Methods 140 CHD patients with 420 coronary artery main branches were enrolled and divided into 4 groups according to the results of coronary angiography (CAG): normal group (101 coronary artery branches without stenosis), mild stenosis group (112 coronary artery branches with stenosis<50%), moderate stenosis group (95 coronary artery branches with stenosis 50%-75%) and sever stenosis group (112 coronary artery branches with stenosis>75%). Three dimensional full volume images were collected through the chest, and the corresponding strain imaging diastolic index (SI-DI) of each direction was calculated, their value for the diagnosis of coronary artery disease was analyzed. Results The longitudinal, area and radial SI-DI of mild coronary artery stenosis group were lower than those of normal group (P<0.05);the longitudinal, area, radial and circumferential SI-DI of moderate coronary artery stenosis group were lower than normal group (P<0.05) and the area, longitudinal and circumferential SI-DI were lower than those of the mild stenosis group (P<0.05);the longitudinal, area, radial and circumferential SI-DI were all lower than those of normal and mild stenosis group (P<0.05), and the area, longitudinal and radial SI-DI were all lower than the moderate stenosis group (P<0.05). ROC curve showed that the sensitivity of longitudinal SI-DI (84.0%) was highest, while the specificity of area SI-DI (78.9%) was the highest. Conclusion RT3D-STI has important significance for early detection and diagnosis of CHD, regional diastolic function decrease of the coronary artery supply area occurs earlier than systolic function reduction, and diastolic function is more sensitive for myocardial ischemia, as a result, SI-DI is able to reflect the stenosis degree of coronary artery in a certain extent.

Intravascular stent as a foreign body induces platelet-monocyte aggregation following implantation, mediates various actions of monocyte, induces monocyte to express tissue factors, promotes fibrin sedimentation at injury site, and accelerates inflammatory reaction of vessel wall injury. In addition, it stimulates platelet aggregation on the stent, activates platelet system and coagulation system, resulting thrombosis. Smooth muscle cells migration to injury site, neointima hyperplasia, and vessel wall reconstruction cause in-stent restenosis. The influential factors that induce restenosis include type of stent, original diseases of the host, stenosis severity before stenting and residual stenosis length after stenting. Inhibition of tunica intima hyperplasia or improvement of neointima as well as vessel wall reconstruction could effectively prevent restenosis.

Objective To evaluate urinary nuclear matrix protein(NMP 22) as an adjuvant diagnostic marker for transitional cell carcinoma of the upper urinary tract. Methods 24 patients with transitional cell carcinoma of the upper urinary tract and 20 patients with benign urinary diseass were evaluated with urinary NMP 22(cutoff level 10U/ml) and voided urinary cytology.NMP 22 was determined using a commercial test kit. Results The sensitivity and specificity of NMP 22 were 87.5% and 85.0% respectively whereas these of cytology were 58.3% and 95.0%. Conclusions Urinary NMP 22 might be an useful adjuvant diagnostic marker for transitional carcinoma of the upper urinary tract.

ObjectiveThe possibility of the hyperplasi a of prostatic outer gland was studied with transrectal ultrasound (TRUS) guided biopsies. MethodsTwenty-seven prostatic outer glands in patients suspicious for prostatic cancer (PCA) were biopsied by TRUS guided, the total sites were 47. The same site was biopsied in sagittal and longitudinal section respectively. The hypoechoic lesion was biopsied 2 times if it was discovered in the outer gland. The histological results were diagnosed in double blind. Results Twenty prostatic inner glands looked symmetrical hyperplasia; 9 outer glands became thin because of the compression, there was no compressive sign in 18 patients; there was a hypoechoic lesion in outer gland of 3 patients. Benign prostatic hyperplasia was diagnosed in the specimens of 47 sites. ConclusionsThe hyperplasia of prostatic outer gland can occur like inner gland because it is glandular tissue.

Objective To evaluate the clinical value of repeat transrectal ultrasound (TRUS) guided biopsy in prostatic cancer (PCA). Methods Repeat TRUS guided biopsy was conducted on 54 patients of the previous benign TRUS guided biopsy at high risk of PCA. Postatic specific antigen ranged in 0.5- 90.0 ?g/L(mean 16.3 ?g/L). Twenty-nine patients were abnormal in digital rectal examination, 21 patients were abnormal in TRUS. Results Forty-seven patients had 2 consecutive times of the biopsy, 6 patients had 3 consecutive times, 1 patient had 4 consecutive times in 54 patients of repeat TRUS guided biopsy. The pathological finding was confirmed in 14 PCA ( 25.9%), and 31 benign prostatic hyperplasia, 5 prostatic intra-epithelial neoplasmia, 4 chronic prostatitis. Conclusions The detection of PCA will be increased by repeat TRUS guided biopsy at high risk of PCA after the previous benign TRUS guided biopsy.

Objective To study the characteristic of the hyperplasia hypoechoic nodules in outer gland of prostate with transrectal ultrasound (TRUS) guided biopsies. Methods 42 patients were suspected of prostatic cancer (PCa) for the existence of hypoechoic nodules in their outer glands of prostate. Each nodule was TRUS guided biopsied in sagittal and longitudinal section, respectively. The histological examinations were performed in double blind. Results Among the 42 patients, there were 22 cases of benign prostate hyperplasia (52.4%) and 20 cases of prostate cancer (47.6%). Conclusions The sonographic findings of the hypoechoic nodules in outer glands included not only PCa, but also benign hyperplasia nodules. Therefore, the definitive diagnosis must dependent on pathologic examinations.
