OBJECTIVETo analyze the factors which influence the safety and prognosis of aorta replacement combined with coronary artery bypass grafting (CABG) for thoracic aortic aneurysm associated with coronary artery disease.

METHODSFrom May 1982 to October 2002, 67 patients with thoracic aortic aneurysm were admitted, and 24 of them combined with CABG. Of the 24 patients, 9 received descending aorta replacement combined with CABG, and the other 15 received the ascending aorta replacement combined with CABG. The treatment results were compared with the other 43 patients only undergoing the thoracic aortic replacement.

RESULTSThe mortality rate of the patients with aorta replacement combined with CABG was 13% (3/24). Though the descending aorta replacement combined with CABG could make the cardiopulmonary bypass time and selective cerebral perfusion time longer, (278 +/- 54) min and (188 +/- 59) min respectively, no significant difference was observed in postoperative complications, 3-year survival rate, 3-year-cardiac-event-free rate compared with the patients only undergoing the thoracic aortic replacement (P > 0.05).

CONCLUSIONSThe aorta replacement combined with CABG can be performed safely, and the revascularization for coronary artery disease is useful for preventing occurrence of cardiac events.

BACKGROUNDProstate stromal cells are known to regulate epithelial growth as well as support and maintain epithelial function. However, how stromal cells regulate epithelial cells and what differences among various histological/pathological prostate stromal cells in prostate cancer progression still remain unclear. This study aimed to investigate the different phenotypes of human various histological/pathological prostate stromal cells, and their role in tumor promotion.

METHODSThe different phenotypes of the human normal prostatic peripheral zonal primary stromal cells (NPPF), transitional zonal primary stromal cells (NPTF), and prostate cancer associated primary stromal cells (CAF) were examined with growth curves and Annexin V-fluorescein isothiocyanate (FITC) assay. The different effects on prostate cancer cell line C4-2B by NPPF, NPTF, and CAF were examined with MTT assay and Annexin V-FITC assay. The gene expression of different histological/pathological prostate stromal cells was profiled by microarray and hierarchical cluster analysis.

RESULTSThe growth rate of NPPF, NPTF and CAF gradually increased, followed by decreasing apoptosis. In vitro stromal-C4-2B cell line co-culture models, the proliferation and apoptosis of C4-2B cell line were differently affected by human various histological/pathological prostate stromal cells. CAF showed the most powerful effect to C4-2B cell line, as opposed to a weakest effect of NPTF. Microarray and hierarchical cluster analysis showed that the differentially expressed genes of CAF and NPPF were less than NPPF and NPTF, or CAF and NPTF. This was consistent with clinical observations that prostate cancer mostly derived from the peripheral zone and does not usually occur in the transitional zone.

CONCLUSIONNPPF, NPTF and CAF possess extremely different biological characteristics and gene expression, which may play an important role in genesis and development of prostate cancer.

OBJECTIVETo study the etiology and preventive measures of the long-term postoperative complication after esophageal replacement with colon for esophageal benign disease.

METHODSTo review the clinical data of 577 patients with esophageal replacement with colon our department, including 123 cases of esophageal benign disease. Of all, there were 25 cases-time for 11 cases following with severe complication: redundancy and dilated colon 12 cases-time, severe stricture of stoma 4, macrocyst esophagus 2, colon-stomach stoma expansion 4, mechanical obstruction of colon 3. The etiology included iatrogenic and functionality. The therapy included stricture form or resection, redundancy segment resection, obstructed segment solution and stoma resection and form.

RESULTSEight cases underwent once operation, 2 case twice, 1 case three times. After operation, 9 cases took food normally, 2 improved symptoms obviously.

CONCLUSIONSThe iatrogenic and functionality factor contributed to severe complication after esophageal replacement with colon for esophageal benign disease. The preventive measure is followed during operation: cervical esophageal-colon anastomosis exceed 2.5 centimeter, abdominal colon-stomach anastomosis reflux, channel width of colon passage, intestinal canal lay up straight. Re-operation is best choice to for local stricture, colon expansion, redundancy and dilated colon.

BACKGROUNDProstate cancer is one of the most common urogenital tumors in the world with an increasing incidence in China. Androgen deprivation therapy is the major therapeutic option for advanced prostate cancer. However, the role of androgen receptor (AR) in hormone-refractory prostate cancer still remains unclear. This work aimed to investigate the role of AR in an androgen independent prostate cancer cell line by in vitro and in vivo studies.

METHODSThe role of AR in the proliferation and invasion/metastasis ability of PC3-AR9 (a PC3 stable clone expressing human AR driven by natural human AR promoter) were examined with MTT assay, soft agar assay, chamber invasion assay, wound healing assay, and also with orthotopic xenograft mouse model.

RESULTSRestoring androgen receptor in PC3 cells resulted in decreased proliferation and invasion/metastasis ability in MTT, soft agar, chamber invasion and wound healing assay. In the mouse orthotopic xenograft model, PC3-AR9 resulted in smaller primary tumors and metastasis tumors, with a lower proliferation rate and higher apoptosis rate.

CONCLUSIONThe AR might function as a tumor suppressor in PC3 cells both in vitro and in vivo.

OBJECTIVE: To summarize the experience of surgical treatments of partial atrioventricular septal defect in 60 patients. METHODS: From April 1999 to April 2004, 60 patients of partial atrioventricular septal defect were operated. Fifty-eight patients were performed with suture of the cleft of mitral valve and the other 2 were given mitral valve replacement; For closure of primum ASD, 53 patients with pericardial patches and 7 with Dacron patches. Coronary sinus was baffled to left atrium with kirklin procedure in 35 cases and baffled to right atrium with McGoon procedure in other 25 cases. Correct the accompanying cardiac deformity at the same time. RESULTS: The hospital mortality was 3.3% (2/60) due to low cardic output syndrome. The incidence rate of complete atrioventricular block was 8.00% (2/ 35) in the group with Kirklin procedure and 6.06% (2/25) in the group with McGoon procedure. There was no statistical significance between the 2 groups (P > 0.05). The follow-up was from 1 month to 5 years, and there was no late death. All cardiac function were improved except middle mitral regurgitation in 1 patient. CONCLUSION Reasonable operative design, refined procedures, avoiding damage to conducting bundles and proper perioperative management are the key points in improving theraeutic effect.

OBJECTIVE: To summarize the experience of diagnosis and surgical treatment of ventricular septal defect with patent ductus arteriosus. METHODS: We retrospectively analyzed the clinical data of 102 cases of ventricular septal defect combined with patent ductus arteriosus who underwent surgical treatment. Preoperative ultrasonic cardiogram (UCG) showed ventricular septal defect combined with patent ductus arteriosus in 82 cases and ventricular septal defect in 20 cases. RESULTS: The hospital mortality was 4.9% (5/102). The reasons for death included low cardiac output syndrome (1 case), pulmonary hypertension crisis (2 cases) and respiratory failure (2 cases). In the remaining patients,the perioperative complications included lung infection (7 cases), pulmonary atelectasis (5 cases), hydrothorax (1 case), and pulmonary hypertension crisis (2 cases); and all the 15 patients recovered lastly. The pulmonary hypertension of all living patients decreased to some degree. The therapeutical effectiveness was satisfactory. CONCLUSION Ventricular septal defect with patent ductus arteriosus is easy to be confused with ventricular septal defect clinically. At the same time,it is diffcult to form a correct diagnosis in some patients by UCG preoperatively. To prevent the occurrence of perfusive lung, it is important to reinforce preoperative diagnosis and exploration during operation. Because pulmonary hypertension in patients with ventricular septal defect with patent ductus arteriosus emerges early and develops quickly, it tends to result in organic pulmonary hypertension which can make patients lose operation chances and influence the long-term therapeutical effect. Surgical operation should be performed as soon as possible. Optimal operative timing and proper perioperative management play important roles in surgical results.

OBJECTIVE: To summarize the surgical treatment of total anomalous pulmonary venous connection (TAPVC). METHODS: We retrospectively analyzed 49 patients with TAPVC as follows: 37 patients with supra-cardiac type in which 35 received anastomoses between the rear wall of the left atrium and the common pulmonary vein and the other 2 received anastomoses between the rear edge of the left atrium roof and the common pulmonary vein; another 12 patients with cardiac type who were incised the upper edge of coronary sinus, connected the common junction of pulmonary veins with the left atrium to form a new left atrium, and repaired the atrial septal defect with a pericardial patch. RESULTS: Forty-six patients recovered and 3 patients died. Thirty-eight patients were followed-up from 3 months to 8 years. The rest patients got fluent pulmonary vein drainage and their heart function resumed to NYHA I. CONCLUSION TAPVC patients should be operated on immediately at definite diagnosis. The fluency of the common pulmonary vein-left atrium anastomoses and proper postoperative care can ensure a satisfactory outcome.
