Objective To explore the role of ubiquitin-proteasome pathway for the gelsolin protein degradation in pancreatic cancer.Methods Pancreatic cancer cell lines BxPC-3 and PANC-1 were first treated with specific 26s proteasome inhibitor lactacystin.Immunoblots of cell lysates were probed for gelsolin expression.To determine whether gelsolin was conjugated to ubiquitin,proteins extracted from the cells with or without lactacystin were immunoprecipitated with anti-gelsolin antibody,followed by Western blot analysis.Results The expression of gelsolin protein increased obviously after treatment with lactacystin in BxPC-3 cells for 12 h.Using anti-gelsolin antibody to immunoprecipitate gelsolin protein and followed by Western blot using anti-ubiquitin monoclonal antibody,it was found that inhibition of proteasome pathway by lactacystin resulted in accumulation of ubiquitylated forms of gelsolin protein.In PANC-1 cell line,there was no significant changes of gelsolin after treatment with lactacystin.Conclusion Ubiquitin-proteasome dependent degradation may be an important regulatory mechanism for gelsolin down-regulation in pancreatic cancer cells.

Objective To investigate the effects of different depth of anesthesia on ScvO2 and ABL in elderly patients with gastrointestinal cancer. Methods Totally 55 elderly patients undergoing gastrointestinal sur-gery were randomly divided into deep anesthesia group(BIS40-49)(group D,n=27)and light anesthesia group (BIS50-59)(group S,n = 28). While SVV value was fixed,fluid management was conducted while monitoring CVP. HR,MAP,the change of central venous oxygen saturation and lactic acid index were recorded in different time points. Results Propofol dosage in group D and group S indicated statistical significance(P<0.05). ScvO2 in group S in T3~T5 was higher than that in T0 and the difference was statistically significant(P < 0.05). Com-pared with ScvO2 in T3 in group D,that in group S was significantly higher and the difference was statistically sig-nificant(P<0.01),but no significant difference was found in other time point in 2 groups(P>0.05). There was no significant difference between and within ABL groups in each time period(P>0.05). There was no significant difference in terms of other indicators between 2 groups. Conclusions For elderly patients with gastrointestinal surgery,shallow anesthesia can improve tissue oxygenation and reduce the amount of anesthetics.

OBJECTIVEAngiotensin-converting enzyme 2 (ACE-2) has been identified as a functional receptor of severe acute respiratory syndrome coronavirus (SARS-CoV), so its gene was cloned and eukaryotic expressed for further insight into mechanisms in SARS-CoV entry and pathogenesis, as well as development of a safe and reliable neutralization assay for SARS-CoV.

METHODSTotal RNA was extracted from right atrial tissue of a patient with right heart failure resected during a valvular replacement surgery by Trizol one-step method, and the full-length ACE-2 encoding gene was acquired by RT-nested-PCR. The ACE-2 encoding gene was then cloned into pcDNA4/HisMax-TOPO eukaryotic expression vector to construct the recombinant plasmid pcDNA4/ ACE-2, which was then transfected into 293 T cell and ACE-2 eukaryotic transient expression was detected by Western Blot. Syncytia inhibition assay was established to detect SARS-CoV neutralizing antibody, and compared parallelly with SARS pseudovirus neutralization assay.

RESULTSThe recombinant plasmid pcDNA4/ ACE-2 could express ACE-2 protein in eukaryotic cells and induce cell-cell fusion between S protein- and ACE2-expressing cells. This cell-cell fusion assay could be used to detect SARS-CoV neutralizing antibody.

CONCLUSIONSARS-CoV receptor ACE-2 gene was successfully cloned and eukaryotic expressed, and used to establish syncytia inhibition assay for SARS-CoV neutralizing antibody assay.

Objective To present the initial experience and results of laparoscopic transvaginal radical cystectomy (LATRC) with orthotopic ileal neobladder. Methods Six female patients with muscle invasive bladder carcinoma underwent LATRC with orthotopic ileal neobladder. The mean age was 61 years (range 55 to 73 years) . The LATRC with orthotopic ileal neobladder consisted of 4 major steps, namely laparoscopic cystectomy, operation on vagina, extracorporeal formation of ileal pouch and laparoscopic urethral pouch anastomosis. With 5 trocars, the bilateral pelvic lymphadenectomy was performed first The ureters were dissected just outside the bladder. Assisted by the uterine manipulator and the LigaSure system, total bladder, uterus and appendage were dissected by the laparoscopic approach. In the transvaginal step, the specimen was removed through the incision of the anterior and posterior vaginal fornix apex and the neovagina was created by the visualized suture. A 30-40 cm ileal loop was taken from the abdominal cavity, isolated, de-tubularized and reconfigured into W shaped pouch with running suture. The anti-refluxing ureter implantation was performed by inserting the 1 cm ureter into the pouch and suturing in place. The urethra neobaldder anastomosis was done under the laparoscope. Results The mean duration of surgery was 6.2 h(range from 4 to 8 h). The estimated blood loss was 665 ml (range from 400 to 1200 ml). All patients achieved urine control and had neither obstruction nor reflux proved by the intravenous pyelography 1-3 months after surgery. The mean value of neobladdermaximum capacity was 427 ml. No vesicovaginal fistula or other serious complication occurred The mean follow-up was 16 months (9-30 months). During the follow-up, there was no mortality. One patient with lymph node involvement developed liver metastasis 8 months post-operatively. Conclusions The LATRC is feasible and effective for the female patients with invasive bladder cancer. Using uterine manipulator and the transvaginal procedure makes the laparoscopic manipulation easier and simpler. The visualized incision and suture on vagina is good for recovery and reducing postoperative vesicovaginal fistula.

Objective To evaluate the efficacy of salvage radiotherapy for supraclavicular lymph node metastasis ( SLNM) after initial treatment in patients with esophageal cancer. Methods A total of 117 patients with SLNM after radical resection for esophageal cancer were enrolled as subjects from 2006 to 2012. All patients received three?dimensional radiotherapy with 1. 8?2. 0 Gy per cycle, 5 cycles a week. The survival rates were calculated using the Kaplan?Meier method and analyzed using the log?rank test. The Cox model was used for multivariate analysis. Results The follow?up rate was 100%. In all the patients, the 1?and 3?year overall survival (OS) rates were 38. 5% and 14. 1%, respectively. The 1?and 3?year OS rates were significantly higher in patients treated with salvage radiotherapy or radiochemotherapy ( n=100) than in patients without any salvage treatment (n=17)(42% vs. 18%,P=0. 008;17% vs. 0%, P=0. 008). The patients treated with radiochemotherapy ( n=32) had significantly higher 1?and 3?year OS rates than those treated with radiotherapy alone (n=68)(59% vs. 34%, 36% vs. 11%, P=0. 002) or without any salvage treatment (n=17)(59% vs. 18%, 36% vs. 0%, P=0. 002). Patients without visceral metastasis (n=80) had significantly higher 1?and 3?year OS rates than those with visceral metastasis ( n=37) ( 44% vs. 27%, P=0. 002;22% vs. 0%,P=0. 002) . Patients with supraclavicular doses of ≥60 Gy in salvage radiotherapy ( n=75) had significantly higher 1?and 3?year OS rates than those with supraclavicular doses of<60 Gy in salvage radiotherapy ( n=25) ( 75% vs. 25%,P=0. 000;24% vs. 8%,P=0. 000) . The multivariate analysis using the Cox model showed that supraclavicular doses of ≥60 Gy, mediastinal metastasis, visceral metastasis, and salvage treatment method were independent factors for survival ( P=0. 001,0. 015,0. 009, 0. 025) . Conclusions Salvage radiotherapy can improve the survival of patients with SLNM in esophageal cancer. Salvage radiotherapy or radiochemotherapy is highly recommended for patients with SLNM alone. A radiation dose of ≥60 Gy in salvage radiotherapy improves survival in patients.
