Objective To evaluate the morphological characteristics of large and small infrarenal abdominal aortic aneurysm (AAA) with 64-slice spiral CT angiography (CTA). Methods Forty-five patients with infrarenal true AAA underwent CTA. The morphological characteristics of AAA were evaluated. The patients were divided into two groups: small AAA (diameter<5 cm, n=20) and large AAA (diameter≥5.0 cm, n=25). The clinical risk factors and morphological characteristics between small and large AAA were compared. The correlation between the size of AAA and the other morphological characteristics was analyzed. Results Compared to patients with small AAA, those with large AAA showed lower systolic blood pressure and larger prevalence of smoking (P<0.05). The length of aneurysms body, diameter of proximal and distal neck, the prevalence of thrombus in posterior wall, and aneurysm wall calcification score in large AAA were significantly larger than those of small AAA (P<0.05). The length of AAA was positively correlated with proximal neck angle (r=0.418, P<0.01) and diameter (r=0.411, P<0.01), whereas negatively correlated with entry angle (r=-0.478, P<0.01)and proximal neck length (r=-0.562, P<0.01). Conclusion The size of infrarenal AAA is associated with the other morphological characteristics.

Objective To study local and systemic immune response in an animal model treated with recombinant hIFN-α-2b-BCG instillation. Methods The MB49 orthotopic bladder cancer model in C57BL/6 mice was established and treated separately with rBCG, wild BCG, wild BCG combined with IFN-α-2b and PBS as the control. The changes of lymphocyte subgroups in peripheral blood were analyzed with FCM, and mTNF-α and mIL-12 in peripheral blood of mice were detected with ELISA.Immunohistochemistry was carried out to detect the local immune reaction, T cell subsets and FAS, in bladder cancer after being treated with rBCG or wBCG. Results The content of CD4+ T lymphocyte was up-regulated in the rBCG group. The CD4+/CD8+ ratio of 2. 63 was up-regulated than pretreatment, significantly different than that of wBCG group(P<0.05). ELISA assay showed that BCG significantly up-regulated the level of mTNF-α and mIL-12 in serum of orthotopie murine bladder cancer mice. The mTNF-α 806 pg/ml, mIL-12 860 pg/ml in rBCG group, was not significantly higher than those in wBCG group and combination group. The immunocompetent cell numbers with CD3, CD4,CD8 phenotype increased significantly in the tumor tissue of BCG treated group than the control(P<0.05). The results of CD4+ in rBCG group and the combination group, and CD8+ in rBCG group were significantly higher than that of the wBCG(P<0.05). The expression of Fas in tumor tissues treated with intravesical BCG was increased(P<0. 05). Conclusions The recombinant IFN-α-2b-BCG can retrieve the disproportion of systemic lymphocyte subgroups, and increases Th1-type factors and local Fas expression in orthotopic murine bladder cancer. The recombinant IFN-α-2b-BCG is effective in regulating local and systemic immune reaction in orthotopic murine bladder cancer model.

Objective To study the feasibility of Bama miniature pig model establishment of type 2 diabetes mellitus (T2DM) by high-fat and high-sugar diet combined with streptozotocin (STZ), and observe the changes in protein kinase B (PKB) and phosphorylation expressions in skeletal muscle, liver, and pancreatic tissues of the miniature pig model. Methods A total of 10 healthy male Bama miniature pigs were randomly divided into two groups:control group (n=5, fed normal diet) and diabetic model group (n=5, fed high-fat and high-sugar diet combined with STZ to establish T2DM Bama miniature pig model). The fasting plasma glucose (FPG) and fasting insulin (FINS) levels were measured, and insulin resistance (HOMA-IR) was calculated in two groups. The PKB and phosphorylation expressions in skeletal muscle, liver and pancreatic tissues were measured using Western blot assay. Results (1) After 10 months of high-fat and high-sugar diet, the body weight, FPG, FINS and HOMA-IR were significantly higher in model group than those of control group (P<0.01). (2) After STZ treatment, compared with control group, there was a further increased level of FPG and a significantly decreased level of FINS in model group (P<0.01). (3) Compared with control group, the PKB and phosphorylation expression levels in skeletal muscle, liver and pancreas were significantly lower in model group (P<0.05). Conclusion The high-fat and high-sugar diet combined with STZ can successfully establish the T2DM miniature pig model. The PKB and phosphorylation expression levels in skeletal muscle, liver, and pancreatic tissues are decreased in model pigs.

Objective To investigate the therapeutic effect of the meso-cavo-atrial shunt (MCAS) in the treatment of combined Budd-Chiari syndrome (BCS). Methods The clinical data of 17 cases of combined BCS with all or bilateral hepatic vein occlusion and long range occlusion or obstruction of inferior vena cava (IVC) were admitted to the Qilu Hospital from February 2000 to May 2004. All patients were treated by MCAS with artificial blood vessels. The pre- and postoperative clinical symptoms, the IVC and portal venous (PV) pressures, the incidence of postoperative complications and the patency rate of the artificial vessels were analyzed. The survival of patients was analyzed using the Kaplan-Meier analysis, and the data were analyzed using the chi-square test and t test. Results No patient died during the perioperative period, and the symptoms of 15 patients disappeared or were relieved after operation, with a significant difference compared with those before operation (χ2 =9.78, P <0. 05 ). Three patients had complications after the operation. The postoperative PV and IVC pressures were decreased by 1.2 cm H2O (1 cm H2O =0.098 kPa) and 18.5 cm H2O, respectively. There were significant differences in the decrease of IVC and PV pressures ( t = 2.38, 3.06, P < 0.05 ). The 1-, 3-, 5-year survival rates were 16/17, 15/17 and 14/17, respectively, and the 5-year patency rate of the artificial vessels was 14/17.Conclusions MCAS can simultaneously relieve IVC and PV hypertension for patients with combined BCS. The postoperative complication rate was decreased, the 5-year survival rate and the patency rate of the artificial vessels were improved after the treatment, so MCAS is an optional surgical method for treating combined BCS.
