Objective To summarize experiences in the perioperative management for combined aortic and mitral valve replacement. Methods One hundred and twenty patients undergoing double valves replacement(DVR) within 10 years were studied. Ameliorate patients' cardiac function before operation. Median sternotomy was performed. The inter-atrial sulcus approach or the right atrial septal approach was chosen, the posterior mitral leaflet and subvalvular apparatus were preserved as much as possible, and DeVega's or Kay's valvuloplasty was performed for moderate and severe tricuspid regurgitation. According to the patient's cardiac function and general condition, active medication with vasomotor drugs, and diuretics as well as intensive postoperative care were administered in the ICU. Results Seven patients died in the perioperative period (in 30 days), and the mortality rate was 5.8%. Early postoperative complications occurred in 22 cases (18%). Conclusion Comprehensive perioperative management could reduce both perioperative mortality and postoperative complications.

Objective Gambogic acid ( GA) can suppress the growth of multiple tumor cells , including gastric carcinoma , hepatoma , hematologic neoplasms and breast carcinoma , but there have been few reports about its effect on urologic neoplasms .This study was to investigate the possible mechanisms of GA inducing bladder cancer cell apoptosis and cell cycle arrest . Methods We cultured human bladder cancer BIU8-7 cell lines in vitor and treated the cells in the logarithmic growth phase with isotonic saline solu-tion (negative control)or GA at the concentrations of 1.0, 2.0, and 3.0μmol/L, respectively.We determined the expression of the Caspase-3 protein in the tumor tissue using the immunohistochemical S-P method and detected GA-induced apoptosis of the bladder cancer cells and cell cycle changes by flow cytometry . Results The expressions of the Caspase-3 protein were 4.28 ±1.86, 5.03 ± 0.78, and 6.47 ±1.31 in the 1.0, 2.0, and 3.0μmol/L GA groups, respectively, significantly higher than 2.13 ±1.27 in the nega-tive control (P<0.05).Flow cytometry showed a gradual decrease of the cells in the G 0/G1 phase and a gradual increase in the G2/M phase , but no obvious change in the S phase . Conclusion Gambogic acid can promote the apoptosis , arrest the cell cycle , and in-hibit the proliferation of bladder cancer cells by increasing the expression of the Caspase -3 protein.

OBJECTIVETo compare robot-assisted laparoscopic radical prostatectomy (RALRP) with laparoscopic radical prostatectomy (LRP) in the treatment of prostate cancer and investigate the clinical application value of RLRP.
METHODSWe retrospectively analyzed 70 cases of prostate cancer treated by RALRP and another 32 cases treated by LRP. We compared the operation time, intraoperative blood loss and transfusion, catheter-indwelling time, postoperative hospital stay, incisal margin positive rate, biochemical recurrence, and normal postoperative urinary continence and penile erectile function between the two groups of patients.
RESULTSAll the operations were successfully accomplished. RALRP exhibited a significant superiority over LRP in intraoperative blood loss and transfusion, catheter-indwelling time, and postoperative hospital stay, urinary continence and erectile function (P < 0.05).
CONCLUSIONRobot-assisted laparoscopic radical prostatectomy, with its advantages of few postoperative complications and well-preserved urinary continence and penile erectile function, is an effective, safe and minimally invasive surgical option for prostate cancer.

BACKGROUND: Adipose-derived stem cells (ADSCs) represent one of the promising cell sources for myocardial regeneration due to their easy accessibility and efficacy in the improvement of cardiac function following myocardial infarction. However, previously reported studies on the underlying mechanism of ADSCs-mediated cardioprotective effect mainly focused on the ADSCs cultured at room air. OBJECTIVE: To test the paracrine actions and anti-apoptotic effect of ADSCs under hypoxic conditions. METHODS: After isolation and culture, neonatal rat myocardial cells were injured by hydrogen peroxide and co-cultured with rat ADSCs under normoxia and hypoxia (10% O2) conditions. Ratio of reduced glutathione to oxidized glutathione (GSH/GSSG) in the cell pellet and levels of vascular endothelial growth factor (VEGF), insulin-like growth factor 1 (IGF-1), and basic fibroblast growth factor (bFGF) were tested by ELISA. Expression of apoptotic proteins Bax and Bcl-2 were determined by western blot. RESULTS AND CONCLUSION: GSH/GSSG, VEGF, IGF-1, and bFGF were decreased in neonatal rat myocardial cells injured by hydrogen peroxide. ADSCs significantly attenuated hydrogen peroxide-induced myocardial apoptosis by increasing the ratio of GSH/GSSG and the secretion of VEGF, IGF-1 and bFGF. ADSCs also down-regulated Bax expression and up-regulated Bcl-2 expression. To conclude, hypoxic conditions can enhance the anti-apoptosis and cardioprotective effects of ADSCs through the paracrine mechanism.
