Objective To explore the methods and clinical value of transrectal ultrasound (TRUS) in detecting rectal gastrointestinal stromal tumor(GIST) with head scanning probe.Methods A total of 12 patients had the ultrasonic examination through the rectum with the head scanning probe.Preoperative ultrasonic findings were compared with the pathological results.Results Of the 12 patients,the patients were divided into three groups,including 3 cases with low-degree severity,6 cases with moderate-degree severity and 6 cases with high-degree severity.The lymph node metastasis was not found near intestines.Rectal GIST appeared as a hypoechoic mass with clear limit、regular form and expanded growth under TRUS.The CDFI showed abundant flow in the tumor and TRUS had an overall accuracy rate of 75.0%(9/12)in the diagnosis of rectal GIST.The accuracy of TRUS in the staging diagnosis of rectal GIST was 83.3%(10/12).Conclusion The TRUS with the head scanning probe is of great value for pre-operative diagnosis and staging of rectal GIST.Rectal water window and felicitous check-up technique can enhance the accuracy of TRUS.

Objective To study the clinical value of color Doppler ultrasonography in typing tuberculous epididymitis.Methods The appearances of color Doppler ultrasound and the findings on operation were analysed in 33 patients with tuberculous epididymitis.Results Of the 33 patients,epididymis appeared as diffusely and heterogeneously enlarged lesions with increased flow in 2 cases,appeared as nodular lesions in 13 cases including nodi with echofree space in 3 cases, nodi with high-level echo patches in 3 cases, and low echo-level nodi in 7 cases. Multiple lesions in scrotum were detected in 17 cases, of whom epididymis up to 11 cases appeared as diffusely enlarged heterogeneous lesions with flow increased.The sonographic appearancs of tuberculous epididymitis could be divided into 3 types:diffusion type, nodus type and complicated type. Nodus type included 3 subtypes: purulence type, calcification type, and cheese type.The accuracy rate of ultrsound diagnosis was 87.9%.Conclusions Testis is easy to be involved when epididymitis appears as diffusion type, so surgical treatments should be early.Purulence type and complicated type need surgical treatments while calcification type does not. Antituberculous drug treatments can be tried before surgical treatments in cheese type.Sonography of urinary system is helpful for the diagnosis of asymptomatic tuberculosis in urinary system when tuberculous epididymitis is first suspected on sonography.

Objective To evaluate the diagnostic role of multi-slice CT(MSCT)angiography for tumors of intra-abdominal testes.Methods MSCT angiography of 5 cases with seminoma of intra-abdominal testes proved by surgery and pathology was analyzed.All patients were male,and the age ranged from 33 to 59 years with the mean of 43.6 years.Results(1)The arterial-supply of tumors completely came from the testicular artery of the same side.The arteries went into tumors from the posterior side.(2)The tumors had comparatively large volume with complete or incomplete amicula.The tumor density of 3 cases was inhomogeneous.The degree of entity augmentation of 5 patients was about 14—25 HU.Conclusion MSCT angiography can reveal the tumor vessel and is essential for the diagnosis of tumors of intra-abdominal testes.

OBJECTIVETo investegate the role of calcineurin (CaN) and its downstream nuclear factor of activated T-cells (NFATc3) in abdominal aorta restenosis following balloon dilatation in rats.

METHODSSD rats were randomly divided into sham-operated group, balloon group and cyclosporine A (CsA) group. The rats in the latter two groups were subjected to abdominal aorta injury with balloon dilatation, and those in CsA group were treated with CsA at the daily dose of 12.5 mg/kg from 3 days before the surgery to the end of the experiment. Thirty days afer the injury, histological analysis of the arterial wall was carried out with HE staining and immunohistochemistry. The expressions of CaN and NFATc3 in the abdominal aortas were detected with rea1-time PCR, and serum concentration of MCP-1 was determined using enzyme-linked immunosorbent assay.

RESULTSIntimal hyperplasia with irregular thickness of the neointima was observed in the aorta of rats with ballon injury. In rats with CsA treatment, the area of the intimal layers and the ratio of the intimal to the medial layers were obviously lower than those in the balloon injury group (P<0.05). Compared to those in the sham-operated group, the expressions of calcineurin protein and mRNA and NFATc3 mRNA in the arterial wall and serum level of MCP-1 increased significantly in the ballon injury group (P<0.05). CsA treatment significantly suppressed aorta restenosis and the alterations of CaN, NFATc3 and serum MCP-1 induced by ballon dilatation (P<0.05).

CONCLUSIONSCaN-NFATc3 signal transduction pathway mediates restenosis of rat abdominal aorta following ballon dilatation, and CsA can attenuate the restenosis by suppressing this pathway.

The paper is aimed to investigate the effect of cyclosporine A (CyA) on the pharmacokinetics of ginkgolide B (GB) in rats, and to look for the mechanism of the changes in pharmacokinetic behaviors of GB. GB concentration in plasma, brain homogenate and urine samples of rats was determined by LC-MS. Effects of CyA on plasma levels, brain distributions as well as urinary excretions after intravenous administration of GB were evaluated. CyA co administrated intravenously at 10 mg kg(-1) or 20 mg kg(-1) significantly increased AUC(0-360 min) (P < 0.01) and decreased total CL of GB in rats. While co administrated CYP3A inhibitor itraconazole (ICZ) has no appreciable effect on the pharmacokinetic behavior of GB. CyA increased the brain uptake of GB in a dose-dependent manner. The brain distribution of GB was significantly increased at 5 min by different doses of CyA (P < 0.001), while at 20 and 60 min only high dose of CyA could significantly increase the levels of GB in the brain (P < 0.01 and P < 0.001). Different P-gp inhibitors CyA or verapamil (VER) or digoxin (DGX) decreased the urinary GB excretion, the urinary excretion of GB in 0-8 h were about 34.8% (P < 0.001), 59.4% (P < 0.001) and 79.7% (P < 0.05) of the control, separately. No appreciable effect of ICZ was observed on urinary excretion of GB. Coadministration of P-gp inhibitors CyA could significantly increase the plasma level, accelerate the brain distribution and decrease the urinary excretion of GB.

OBJECTIVETo study the relationship between angiogenesis and lymphangiogenesis with the expression of vascular endothelial growth factor C (VEGF-C) and VEGFR-3 in human non-small cell lung cancer (NSCLC).

METHODSSamples of 76 NSCLC cases with the neighboring noncancerous tissue were studied using anti- VEGF-C, VEGFR-3 and CD34 antibodies. Assessment of lymphatic vessel density and microvessel density (MVD) were performed.

RESULTSVEGF-C expression in NSCLC was associating with the differentiation of tumor cells (P = 0.009). Expression of VEGF-C and VEGFR-3 was significantly associated with lymph node metastasis (P = 0.008 and P = 0.013 respectively) and lymphatic invasion (P = 0.027 and P = 0.020 respectively). A significant positive correlation was found between VEGF-C in cancer cells and VEGFR-3 in lymphatic endothelial cells (P = 0.009). The number of lymphatic vessels (P = 0.006) and microvascular (P = 0.046) in VEGF-C positive tumors was significantly larger than in VEGF-C-negative tumors. Lymphatic vessel density was closely related to lymph node metastasis (P = 0.010), lymphatic invasion (P = 0.019) and clinical stages (P = 0.015). MVD was closely related to blood metastasis (P < 0.001) and clinical stages (P < 0.001). Patients with positive VEGF-C expression had a worse prognosis than those with a negative VEGF-C expression (P < 0.001).

CONCLUSIONSVEGF-C/VEGF-D in NSCLCs, are related to lymphangiogenesis and angiogenesis, as well as to the occurrence and the development of lung cancers. VEGF-C promotes intratumoral lymphangiogenesis via VEGFR-3, resulting facilitated invasion of cancer cells into the lymphatic vessels. VEGF-C expression can be a useful predictor of poor prognosis in NSCLC.
