  • Expression of Livin in Esophageal Carcinoma and Its Correlation with P53,Bcl-2

    Abstract: Objective To investigate the expression of inhibitor of apoptosis gene Livin and its relationship with expression of P53,Bcl-2 in esophageal carcinoma tissues. Methods The expression of Livin messenger ribonucleic acid (mRNA) in 36 esophageal carcinoma tissues and 18 paracancerous tissues were measured by reverse transcriptionpolymerase chain reaction (RT-PCR) combined with silver staining technique. The expression of Livin, P53 and Bcl-2 proteins were detected by immunohistochemical method (streptavidin-peroxidase). Results RT-PCR results: Livin mRNA positive expression of esophageal carcinoma tissues was more evident than that of paracancerous tissues, the expression of both variants was simultaneous basically. Immunohistochemical results: the Livin protein positive expression rate of esophageal carcinoma tissues was higher evidently than that of paracancerous tissues(Plt;0.01). Livin protein positive expression rate of external coat of esophagus invaded by carcinoma was higher than that of tunica muscularis esophagi invaded by carcinoma(Plt;0.05); Livin protein positive expression rate of lymph node metastasis was higher than that of normal lymph node (Plt;0.05). The expression of Livin protein was not related to the expression of P53 protein(χ2=1.00,P=0.505),but it was positively related to the expression of Bcl-2 protein(χ2=10.60,P=0.003). Conclusion Aberrant expression of Livin may be a new target for diagnosis and gene treatment of esophageal carcinoma.The aberrant expression of Livinand apoptosis related gene Bcl-2 may play synergetic roles in process of carcinogenesis of esophageal carcinoma.

  • The Expression and Clinical Significance of Livin and Caspase-3 in Patients with Middle Ear Cholesteatoma

    ObjectiveTo study the expression of inhibitor of apoptosis proteins (Livin) and aspartate-specific cysteine protease-3 (Caspase-3) in patients with middle ear cholesteatoma and its clinical significance. MethodWe selected 51 patients with cholesteatoma of the middle ear treated between April 2013 and March 2014 in our department to be our study subjects. Streptaridin-perosidase immunohistochemical method was adopted to detect the expression of Livin and Caspase-3 in the middle ear cholesteatoma epithelium and normal skin of external acoustic meatus. SPSS 17.0 software package was used for statistical analysis. ResultsThe expression of Livin in cholesteatoma epithelium was significantly higher than that in the normal skin tissue of the external auditory canal (P<0.05), and the expression of Caspase-3 in cholesteatoma epithelium was significantly higher than the normal skin tissue in the external auditory canal (P<0.05). The expression of Livin and Caspase-3 in cholesteatoma epithelium was positively correlated (r=0.49, P<0.05). ConclusionsThere is a balance between apoptosis and inhibition of apoptosis in normal tissues, and when there is abnormal expression of Livin and Caspase-3 in normal tissues, it will cause cell apoptosis and apoptosis-inhibitory balance disorders, which causes middle ear cholesteatoma.

  • Expressions of Livin,Caspase-3, Bcl-2 in Lung Tissue of NSCLC and their Prognostic Significances

    Objective To study the expressions of Livin, Caspase-3 and Bcl-2 in lung tissue of nonsmall cell lung cancer ( NSCLC) , and their relationship with the clinicopathological features and prognosis of NSCLC. Methods The expressions of Livin, Caspase-3 and Bcl-2 proteins were evaluated by immunohistochemical method in 87 NSCLC samples and 40 lung benign tissues. The relationship of their expressions with the clinicopathological features and prognosis of NSCLC were analyzed by Spearman’s Rank correlation and COX Regression. Results More NSCLC tissues showed expression of Livin than lung benign tissues( 72. 41% vs 0. 0% , P = 0. 000 ) , and the expression of Caspase-3 was significantly decreased ( 67. 82% vs 87. 5%, P lt; 0. 05 ) . The proteins of Livin, Caspase-3 and Bcl-2 were detected in the endochylema but none was detected in nucelus. There was no relationship between the expression of each of these proteins and the clinicopathological features of NSCLC such as histologic type, tumor differentiation,lymph node metastasis, TNM stage, the size of tumor, and tumor site. The expression of Livin was correlated with Caspase-3 and Bcl-2 expressions ( r1 = - 0. 260, P = 0. 015; r2 = 0. 351, P = 0. 001) . Livin, Caspase-3 and Bcl-2 were not independent prognostic factors of NSCLC. Conclusions The expression of Livin and Bcl-2 are up-regulated in NSCLC. The expression of Livin is positively correlated with that of Caspase-3 and Bcl-2, they might interact with each other in the carcinogenesis and development of NSCLC. The levels of Livin, BCl-2 and Caspase-3 proteins are not independent factors affecting the prognosis of lung cancer patients.

  • Intraoperative Monitor and Modulation of Portal Vein Hemodynamics During Living Donor Liver Transplantation to Prevent Small-for-Size-Syndrome 

    Objective To analyze the effect of monitoring and modulating the portal vein pressure and blood flow during living donor liver transplantation (LDLT) on preventing small-for-size-syndrome (SFSS). Methods Data of forty-four LDLT recipients between Oct.2007 and Oct.2008 were reviewed. Actual graft-to-recipient weight ratio(GRWR), portal vein flow and pressure during operation and syndrome of SFSS after operation were recorded. The patients received splenectomy or splenic artery ligation according to actual GRWR, portal vein flow and pressure and WBC. Relationships between patients’ GRWR, portal vein flow, portal vein pressure and occurrence of SFSS were analyzed. Results Six patients received splenectomy and 7 patients received splenic artery ligation to decrease the portal vein flow and pressure during the operation. The portal vein flow and pressure decreased after splenectomy (Plt;0.05). The portal vein pressure decreased (Plt;0.05) and the portal vein flow had no significant change after splenic artery ligation (P>0.05). No SFSS occurred after operation. Conclusion Modulation of portal vein flow and pressure by splenectomy or splenic artery ligation during LDLT operation can decrease the portal vein flow and pressure, and which can prevent the incidence of SFSS.

  • PREVENTION OF COMPLICATIONS AFTER HEPATIC ARTERY RECONSTRUCTION IN ADULT-TO-ADULT LIVING DONOR LIVER TRANSPLANTATION

    Objective To summarize the experience of the prevention of early arterial compl ications after hepatic artery (HA) reconstruction in adult-to-adult l iving donor l iver transplantation (A-A LDLT). Methods Between January 2002and March 2008, 127 patients underwent A-A LDLT. Of the 131 donors (127 cases of right lobe graft, 4 cases of left lobe graft), there were 69 males and 62 females with a mean age of 36.2 years (range, 19-65 years); in 127 recipients, there were 109 males and 18 females with a mean age of 41.9 years (range, 18-64 years). All patients underwent microsurgical reconstruction of HA between grafts and recipients. The artery of graft was anastomosed to the right HA in 62 cases, to the proper HA in 34 cases, to the left HA in 7 cases, to the common HA in 6 cases, and aberrant right HA rising from superior mesenteric artery in 8 cases. Interposition bypass using great saphenous vein (GSV) was performed between the donor right HA and recipient common HA in 5 cases. Bypass was performed between the donor right HA and recipient abdominal aorta using GSV in 2 cases, or using cryopreserved cadaveric il iac vessels in 3 cases. Results Of these 127 cases, hepatic artery thrombosis (HAT) occurred in 2 recipients (1.6%) at 1 day and 7 days following A-A LDLT, which were successfully revascularized with GSV between right HA of donor and abdominal aorta of recipient, HAT in 1 patient occurred on the 46th postoperative day with no symptom. No other arterial compl ication such as HA stenosis and aneurysm occurred in recipients. All patients were followed up 9-67 months. At 1, 2, and 3 years, actual survival rateswere 82.2%, 64.7%, and 59.2%. No death was related to HA compl ication in peri-operative period. Conclusion The anatomic structure and variation of HA, the pathological changes, as well as surgical technique in HA reconstruction, have direct impact on the risk of postoperative compl ications of HA reconstruction.

  • TREATMENT OF MULTIPLE ARTERIES IN RENAL TRANSPLANTATION FROM LIVING RELATED DONORS

    To discuss renovascular reconstruction during l iving related donor kidney transplantation (LDKT). Methods Seventy-seven cases of LDKT from April 2006 to March 2008 were retrospectively analyzed, including 63 cases in single renal artery group and 14 cases in multi ple artery group. In multi ple artery group, there were 3 cases of three arteries and 11 cases of double arteries; 9 cases of donated left kidneys and 5 cases of donated right kidneys. Potential donors underwent fully medical evaluation before operation, including donor-reci pient human leucocyte antigen matchingand a cross match test. The donor’s operation of the incision either underneath the 12th rib approaching the dorsal lumbar was performed and the transplantation operation adopted the extraperitoneal approach in the contralateral fossa il iac. The arteries in the multiple artery group were implanted onto the external (or common) il iac artery different from the orthodox method. Results In multiple artery group, no blood transfusion during operation was performed, no compl ication occurred after operation and all donors were discharged after 7-9 days of postoperation. After a follow-up of 3 months to 1 year, all the recipients kept normal kidney function without renal tubule necrosis, renal artery embol ism, vascular stenosis, urinary fistula and ureter necrosis. The ultrasound examination showed that the transplanted kidney had good blood supply. There was no significant difference in the time of urine secretion, serum creatinine level after 1 week of operation, length of hospital ization between the multiple artery group and the single artery group (P gt; 0.05). Conclusion The accurate treatment of multiple artery anastomosis are critical for the safety of the LDKT.
