Objective To explore the expressions of Survivin and VEGF and relationship between them in hepatocellular carcinoma(HCC).Methods The expressions of Survivin protein and VEGF protein in 50 HCC.30 cirrhosis and 10 normal tissues were assessed by immunohistochemical method.The expressions of Survivin mRNA and VEGF mRNA in 50 HCC,30 cirrhosis and 10 normal tissues were assessed by in situ hybridization.Results The expressions of Survivin and VEGF in cancer tissues,cirrhosis tissues,normal tissues weresignificantly different. The expression of Survivin in HCC tissues was stronger than that in cirrhosis,but the expreesion of VEGF in cirrho- sis was stronger than that in HCC tissues.Conclusion The expression of survivin.is closely associated with the ex- pression of VEGF in HCC and they take positive correlation.The abnormal expressions of Survivin and VEGF are closely associated with the development of HCC.They may play important roles in the development of HCC.

OBJECTIVETo explore clinical effect of vacuum sealing drainage (VSD) combined with discontinuous windowing technique for repairing large area exposed wounds of Achilles tendon.

METHODSFrom July 2009 to May 2014, 11 patients with large exposed wounds of Achilles tendon were treated, including 5 males and 6 females with an average age of 43 years old (aged from 7 to 65 years old). Among them, 4 cases were skin necrosis caused by heavy objects abrasion and contusion; 3 cases were caused by distal tibiofibula fractures; 3 cases were caused by bicycle-spoke injuries; 1 case was caused by diabetes. Areas of exposed Achilles tendon were from 6 cmx3 cm to 14 cmx5 cm without tendon rupture or bone exposed. After debridement, discontinuous fenestration on Achilles tendon was made by knife blade parallel with longitudinal axis of Achilles tendon, combined with Vacuum Sealing Drainage (VSD) treatment.

RESULTSAfter drainage treatment with one VSD cycle (5 to 7 days), abundant fresh granulation tissues were growing on all wounds and survived well after the second phase dermatoplasty. All patients were followed up for 12 to 24 months, the color of skin flap was good, the texture was soft without burst. At 3 to 4 months after operation, subcutaneous fat was appeared under the flap, the skin was sliding, movement of ankle joints was good. No delayed Achilles tendon rupture were occurred.

CONCLUSIONVacuum sealing drainage (VSD) combined with discontinuous fenestration is a simple, safe and effective method for repairing large area exposed wounds of Achilles tendon,which could minimize the secondary damage caused by wounds of skin flap grafting.

OBJECTIVETo investigate the surgical treatment and prognosis for recurrent colon cancer after curative resection.

METHODSThe clinical data of 102 recurrent colon cancer cases from January 1997 to December 2005 were analyzed retrospectively. Obtained data were analyzed by Statistical Package for the Social Sciences (Release 11.5, SPSS, Inc). The related factors were underwent chi2 analysis,survival analysis were estimated using the Kaplan-Meier method and compared using the Log-rank test. COX regression was used in multivariate analysis.

RESULTSUnivariate analysis revealed that obstruction of primary tumors, CEA level before reoperation, number of recurrence, time of recurrence, and reoperation type were significant statistically. COX regression analysis revealed that number of recurrence, reoperation type was the most important prognostic factor.

CONCLUSIONThe recurrent colon cancer still need active surgical treatment in order to prolong the survival time.

OBJECTIVETo evaluate the effect and safety of transurethral prostatectomy with the bipolar plasmakinetic technique (PKRP) in the treatment of benign prostate hyperplasia (BPH).

METHODSA total of 712 BPH patients underwent transurethral prostatectomy with the bipolar plasmakinetic technique. The patients averaged 70.6 years of age and 52 g (range 35-102 g) in estimated prostate weight preoperatively. Comparative analyses were made on the maximum urine flow rate (Qmax), residual urine volume and scores on IPSS and QOL obtained pre- and post-operatively.

RESULTSThe operations lasted 20-120 minutes (mean 51 min), the resected tissues weighed 15-96 g (mean 46 g), and no transurethral resection syndrome (TURS) occurred. The catheters were removed 4 -5 days after surgery. The patients were followed up for 1 -52 months (mean 27.6 mo). Obvious reduction was observed in the average Qmax from 4.7 ml/s preoperatively to 19. 1 ml/s postoperatively, in the mean IPSS score from 26.6 to 5. 8, and in the mean QOL score from 5.4 to 1.7, all with significant differences (P < 0.01).

CONCLUSIONTransurethral prostatectomy with the bipolar plasmakinetic technique is a safe and effective means for the treatment of BPH.

OBJECTIVETo investigate the surgical treatment of ovarian metastasis from colorectal cancer.

METHODSThe clinical data of 62 cases suffering from ovarian metastasis from colorectal cancer, collected from Jan. 1990 to Dec. 2005, were analyzed retrospectively.

RESULTSThe median survival time of 62 colorectal cancer patients with ovarian metastasis was 23 months. The median survival time of 19 patients with simple ovary metastasis was 31 months, while that of 43 patients with ovary and other organ metastasis was 21 months. The median survival time of 28 patients (45.2%) treated with radical resection was 31 months, while that of 34 patients (52.8%) treated with palliative resection was 20 months, the difference between two groups was significant. Fifty-one patients (82.3%) were treated with double-sided ovarian resection, and 42 of them (17.7%) received hysterectomies at the same time. Eleven patients received one-sided ovarian resection, and 8 of them were resected the metastatic ovaries on the other side in 3 to 10 months.

CONCLUSIONSThe patients with ovarian metastases from colorectal cancer need double-sided ovarian resection, and radical resection is able to prolong the survival time.

OBJECTIVETo evaluate the effect and safety of transurethral prostatectomy with the bipolar plasma kinetic technique (PKRP) in the treatment of benign prostate hyperplasia(BPH).

METHODSTwo hundred and ninty-seven BPH patients underwent transurethral prostatectomy with the bipolar plasma kinetic technique. The preoperative estimated weight of the prostate ranged from 35 g to 102 g, averaging 52 g.

RESULTSThe operation lasted 40 approximately 65 min, averaging 51 min. The resected tissues weighed 40 approximately 80 g, averaging 46 g. During the operation no transurethral resection (TUR) syndrome occurred. The catheter was removed 4 approximately 5 days after the operation, all with fluent urination. The patients were followed up for 2 approximately 33 months. IPSS decreased from average 31.5 preoperatively to average 6.8 postoperatively (P < 0.001). Average maximum flow-rate (Q(max)) decreased from 6.3 ml/s preoperatively to 18.6 ml/ s postoperatively (P < 0.001). Preoperative average residual urine was 97 ml and reduced to average 9 ml after the operation. Temporary incontinence occurred in 4 cases, perioperative hemorrhage in 2, and urethral stricture in 1.

CONCLUSIONTransurethral prostatectomy with the bipolar plasma kinetic technique is a safe and effective means for the treatment of BPH.

OBJECTIVETo summarize the surgical treatment experiece and to investigate the prognosis of the patients with ovarian metastasis from colorectal cancer.

METHODSThe data of 67 patients with synchronous or asynchronous ovarian metastasis from colorectal cancer surgically treated between January 1989 and December 2005 were collected and analyzed retrospectively using Statistical Package for the Social Sciences (Release 11.5, SPSS, Inc). Prognostic factors were analyzed using chi2 test. Survival analysis was estimated by the Kaplan-Meier method and compared using the log-rank test. Multivariate analysis was carried out by Cox regression.

RESULTSThe overall 1-, 3- and 5-year survival of these 67 patients was 71.0%, 18.7% and 9.2%, respectively. Univariate analysis revealed that the metastasis was confined in the ovary or pelvis only, unilateral/double ovarian metastasis, and operation mode were all statistically significant prognostic factors (P <0.05). Cox regression analysis showed that the operation mode was the most important prognostic factor (OR = 3.531, P <0.001).

CONCLUSIONSurgical treatment is still the most effective mode in the treatment for the ovary metastasis from colorectal cancer.

Objective Dexmedetomidine(Dex)is a highly selective α2 adrenoceptor agonist that reduces blood pressure and heart rate.However,its ability to provide stable hemodynamics and a clinically significant reduction in blood loss in spine surgery is still a matter of debate.This study aimed to investigate the effects of Dex on intraoperative hemodynamics and blood loss in patients undergoing spine surgery. Methods The Web of Science,MEDLINE,EMBASE,and the Cochrane Library were searched up to February 2023 for randomized controlled trials(RCTs)including patients undergoing spine surgeries under general anaesthesia and comparing Dex and saline.A fixed-or random-effect model was used depending on heterogeneity. Results Twenty-one RCTs,including 1388 patients,were identified.Dex added the overall risk of intraoperative hypotension(odds ratio[OR]:2.11;95％confidence interval[CI]:1.24-3.58;P=0.006)and bradycardia(OR:2.48;95％CI:1.57-3.93;P=0.0001).The use of a loading dose of Dex led to significantly increased risks of intraoperative hypotension(OR:2.00;95％CI:1.06-3.79;P=0.03)and bradycardia(OR:2.28;95％CI:1.42-3.66;P=0.0007).For patients receiving total intravenous anesthesia,there was an increased risk of hypotension(OR:2.90;95％CI:1.24-6.82;P=0.01)and bradycardia(OR:2.66;95％CI:1.53-4.61;P=0.0005).For patients in the inhalation anesthesia group,only an increased risk of bradycardia(OR:4.95;95％CI:1.41-17.37;P=0.01)was observed.No significant increase in the risk of hypotension and bradycardia was found in the combined intravenous-inhalation anesthesia group.The incidence of severe hypotension(OR:2.57;95％CI:1.05-6.32;P=0.04),but not mild hypotension,was increased.Both mild(OR:2.55;95％CI:1.06-6.15;P=0.04)and severe(OR:2.45;95％CI:1.43-4.20;P=0.001)bradycardia were associated with a higher risk.The overall analyses did not reveal significant reduction in intraoperative blood loss.However,a significant decrease in blood loss was observed in total inhalation anesthesia subgroup(mean difference[MD]:-82.97;95％CI:-109.04--56.90;P＜0.001). Conclusions Dex increases the risks of intraoperative hypotension and bradycardia in major spine surgery.The administration of a loading dose of Dex and the utilization of various anesthesia maintenance methods may potentially impact hemodynamic stability and intraoperative blood loss.
