Objective To assess the imaging characters and clinical applications of triphasie spiral computer tomography (CT) scanning in ureteral lesions. Methods We analyzed of 76 eonseeutive eases of elinieaUy evidenced ureteral lesions using the cross - sec-fional images and CTU derived from triphaaie spiral CT scanning retrospectively. Results Twetny - four cases of 76 ureteral lesions pa-tients were diagnosed as ureteral tumor, resulting in severe urinary tract obstruction. The shape, size, number, regional ureter wall in-flammatory infiltration of visible mass were verified as well. Twetny- six cases were caused by ureteral stones. The "edge" sign was shown clearly. Ten cases were ureteral inflammation, characterized by different ureteral wall thickening and enhancement feature. Eight cases were ureteral tuberculosis that secondary to renal tuberculosis. Uneven ureteral wall thickening, stiffness and mild to moderate densi-ty were shown in CT scanning. Ureteral congenital malformations were found in 3 patients. The other five cases were caused by exogenous factors. CT scanning could identify the mass general profile. Conclusion Triphasic spiral CT scanning plays an important role in ureteral lesions diagnosis and differentiation from other similar diseases.

Objective To investigate the role of RhoA and Rho kinase system in the onset of labor. Methods Forty term pregnant women, who delivered through cesarean section at the Xiangya Second Hospital of Central South University from February 2007 to November 2007, were selected and divided into 2 groups: 20 in labor group and 20 in non-labor group. Another 20 non-pregnant women undergoing hysterectomy due to cervical intraepithelial neoplasia were chosen as the control. Real-time fluorescence quantitative RT-PCR and western blot were applied to detect the expression RhoA and ROCKⅠ mRNA and protein in uterine smooth muscle tissue and the correlation between the mRNA and protein expression of RhoA and ROCKⅠ were analyzed. Results (1) The mRNA expressions of both RhoA and ROCKⅠ were detected in all groups, and higher levels were found in the labor group than in the non-labor group and the control [RhoA mRNA: (3.51±0.56)×10-3 vs. (2.75±0.52)×10-3 and (2.11±0.54)×10-3; ROCKⅠ mRNA: (4.07±0.66)×10-3 vs. (2.71±0.52)×10-3 and(2.01±0.23)×10-3, P<0.01]. (2) RhoA and ROCKⅠ proteins were also identified in all three groups, and the expressions in the labor and non-labor group were higher than those of the control (RhoA protein: 0.72±0.23 and 0.64±0.17 vs. 0.46±0.15; ROCKⅠ protein: 0.56±0.14 and 0.42±0.16 vs. 0.29±0.08, P<0.01). (3) The expression of RhoA mRNA and ROCKⅠ mRNA were positively correlated in each of the three groups (r=0.73,P<0.01), and the same was found in the expression of RhoA protein and ROCKⅠ protein (r=0.37,P<0.01). Conclusion The increased expression of RhoA and Rho kinase may play an important role in the initiation of labor.

Objective To assess the imaging characters and clinical applications of triphasic spiral computer tomography(CT) scanning in ureteral lesions.Methods We analyzed of 76 consecutive cases of clinically evidenced ureteral lesions using the cross-sectional images and CTU derived from triphasic spiral CT scanning retrospectively.Results Twetny-four cases of 76 ureteral lesions patients were diagnosed as ureteral tumor,resulting in severe urinary tract obstruction.The shape,size,number,regional ureter wall inflammatory infiltration of visible mass were verified as well.Twetny-six cases were caused by ureteral stones.The "edge" sign was shown clearly.Ten cases were ureteral inflammation,characterized by different ureteral wall thickening and enhancement feature.Eight cases were ureteral tuberculosis that secondary to renal tuberculosis.Uneven ureteral wall thickening,stiffness and mild to moderate density were shown in CT scanning.Ureteral congenital malformations were found in 3 patients.The other five cases were caused by exogenous factors.CT scanning could identify the mass general profile.Conclusion Triphasic spiral CT scanning plays an important role in ureteral lesions diagnosis and differentiation from other similar diseases.

To study the clinicopathological features of breast carcinoma with responsive granuloma. MethodsFive cases of breast carcinomas with responsive granuloma were investigated by morphological observation. ResultsAll the five patients had noncaseating epithelioid granulomas. Multinucleated giant cells, predominantly of Langhans type, were present in granulomas. The granulomas were restricted to the carcinoma, and no responsive granulomas were evident in the regional lymph nodes. None of the patients had clinical evidence of systemic granulomatous disease. ConclusionDifferential diagnosis of breast carcinoma with responsive granuloma should include the carcinoma with osteoclast-like giant cells, metaplastic the carcinoma with osteoclastic giant cells, granulomatous lobular mastitis, stromal responsive giant cells, and carcinoma with sarcoidosis or tuberculosis of the breast.

CMTM3 and CMTM7 are two newly discovered anti-oncogenes,which exist in various kinds of organs and tissues and having multiple biological functions including cell proliferation,differentiation,migration,and apoptosis. Recently,it has been shown that these two anti-oncogenes have closely relationship with gastrointestinal tract tumor,which can inhibit the growth of esophageal,gastric,and colorectal cancer. In this review article,the advances in study of the relationship between these two anti-oncogenes and tumors of gastrointestinal tract were summarized.

Urotensin II (U-II), a cyclic peptide has been initially identified as a neuropeptide of teleost fish. Subsequently, U-II has been characterized in the brain of the European green frog and has also been cloned from the human genome. Human U-II (human U-II, hU-II), composed of 11 amino acid residues is rich in cardiovascular and nervous system. As an endogenous ligand for UT receptor, hU-II exerts a broad spectrum of biological actions, such as vasoconstriction and vasorelaxation, facilitating proliferation of cardiac cells, regulating the cardiac function and playing an important role in pathogenesis of some cardiovascular diseases such as coronary heart disease and cardiac failure. The effects of hU-II on cardiovascular system were briefly reviewed as follows.
