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.
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 paracancerous tissues were measured by reverse transcriptionpolymerase 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 paracancerous 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 paracancerous 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.
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.
Objective To explore the allocation of necessary living goods for the emergency medical rescue teams at Lushan earthquake sites. Methods The living goods requirements of 59 emergency medical rescue members at Lushan earthquake sites were investigated using a questionnaire and then analyzed, in order to provide references for the allocation of necessary living goods for emergency medical rescue teams in future. Results The top five necessary living goods for emergency medical rescue members at earthquake sites were food, drinking water, toilet, communication product, and bedclothe. The needs of bath of the members who stayed longer than 3 days were more than the members who stayed shorter than 3 days, with a significant difference (Plt;0.05). The number of living goods that female members need were more than that male members need (Plt;0.05). Conclusion For improving the work efficiency and quality of life, emergency medical rescue teams need to be equipped with not only the medical supplies, but also necessary living goods based on the length of stay and the ratio between male and female.
Objective To analyze the effects and recurrence rate of single miconazole and the miconazole plus living preparation of lactobacillus for the treatment of the uncomplicated vulvovaginal candidiasis. Methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 4, 2008) MEDLINE (1966 to January 2009); PubMed (1966 to January 2009); EMbase (1966 to January 2009); CNKI (1966 to January 2009), and the Chinese Biomedicine Database (CBM) (1966 to January 2009) to identify randomized controlled trials of single miconazole versus the miconazole plus living preparation of lactobacillus.The quality of the included trials was assessed. RevMan 5 software was used to conduct meta–analysis. Results Eight trials involving 5 156 patients were included in the effect analysis. Meta-analysis showed miconazole plus with living preparation of lactobacillus was better compared with just miconazole (RR=0.96, 95%CI 0.92 to 1.00, Z=2.12, P=0.03; RR=0.92, 95%CI 0.85 to 0.99, Z=2.17, P=0.03).Seven trials involving 4 852 patients were included in recurrence rate analysis. Meta-analysis showed miconazole plus living preparation of lactobacillus had lower recurrence rate compared with single miconazole (RR=3.72, 95%CI 1.94 to 7.13, Z=3.97, Plt;0.000 1; RR=12.85, 95%CI 8.27 to 19.96, Z=11.37, Plt;0.000 01). Conclusion Currently available evidence shows that the effect in the combined group is better, and the recurrence rate is lower.
目的:探讨Livin基因在人胆管癌组织及胆管癌细胞系中的表达情况及其与胆管癌发 生发展之间的关系。方法:采用免疫组织化学技术（SP法）检测Livin基因蛋白在45例人胆管 癌标本及及40例癌旁胆管组织、20例正常胆管组织标本中的表达；同时采用RTPCR法及SP 法检测了Livin基因mRNA和蛋白在人胆管癌细胞系QBC939及非肿瘤细胞系HT1080中表达。 结果:Livin在胆管癌组织中表达阳性率为57.8%，而癌旁胆管组织、非癌胆管组织中未能检 测到Livin表达。Livin表达与性别、年龄、肿瘤大小及肿瘤分化程度无关。在有淋巴结转组 中，Livin阳性表达率（70.4%）明显高于无淋巴结转移组（38.9%）。在人胆管癌细胞QBC939 中，Livin mRNA及蛋白均特异性表达，而非肿瘤细胞系HT1080未见Livin表达。结论:Livin 基因在人类胆管癌组织和细胞系中选择性高表达，其可能与胆管癌发生、发展及预后密切相 关。
【Abstract】ObjectiveTo report the author’s experience with the first case of an adult-to-adult living donor liver transplantation (LDLT) for Budd-Chiari syndrome (BCS) using cryopreserved vena cava graft in postheptic vena cava reconstruction. MethodsA 35-year-old male patient with a diagnosis of BCS complicated with inferior vena cava (IVC) obstruction received medical treatment and radiologic intervention for nine months, no relief of the symptoms could be achieved. Finally, the patient underwent LDLT, which required posthepatic vena cava reconstructed using cryopreserved vena cava graft. ResultsThe patient has had an uneventful course since the LDLT. ConclusionWe believe that LDLT combined with posthepatic IVC reconstruction using cryopreserved vena cava graft is considered to be a sound modality for IVC obstructed BCS.
Objective To summarize the changes of serum ceruloplasmin levels and urinary copper excretion in Wilson’s disease （WD） after living-related liver transplantation(LRLT) and orthotopic liver transplantation(OLT). Methods From September 2000 to November 2003, 140 cases liver transplantation were performed in our Liver Transplantation Center, LRLT and OLT were carried out in 26 patients with WD, three of them had fulminant hepatic failure and the others had end-stage hepatic insufficiency. All the recipients had low serum ceruloplasmin levels 〔(124.8±22.8) mg/L〕 and high urinary copper excretion 〔(1 524.8±328.6) μg/24h〕 before transplantation. The serum ceruloplasmin levels and urinary copper excretion were within normal limits in 22 donors 〔(230.4±29.6) mg/L〕 and ＜50 μg/24h〕. Results All recipients recovered satisfactorily. After operation 1, 3, 6,12 months, in OLT group, serum ceruloplasmin level and urinary copper excretion were (320.2±36.8) mg/L, (380.4±45.6) mg/L, (360.5±37.6) mg/L, (356.2±27.6) mg/L and (240.4±22.8) μg/24h, (86.5±10.6) μg/24h, (54.2±6.8) μg/24h, (46.8±3.4) μg/24h; While in LRLT group, serum ceruloplasmin levels and urinary copper excretion were (216.8±20.4) mg/L, (248.5±32.6) mg/L, (285.4±44.3) mg/L, (260.2±36.6) mg/L and (380.8±37.6) μg/24h, (150.6±24.5) μg/24h, (75.5±9.6) μg/24h, (60.3±5.8) μg/24h. Conclusion OLT and LRLT are curative procedure in WD manifested as fulminant hepatic failure and/or end-stage hepatic insufficiency. After liver transplantation, the serum ceruloplasmin level can increase to its normal range while urinary copper excretion decreases.
【Abstract】Objective To study the anatomy of the hepatic arteries and imitate the way to deal with the hepatic arteries in the living liver transplantation of the left lateral lobe.Methods Thirty normal adult livers were anatomyzed and 30 casting models of livers were observed. The lengths, diameters and distributaries of the hepatic arteries were described.Results The blood supply of the left lateral region came from proper hepatic artery, left hepatic artery and middle hepatic artery. The aberrant arteries included left inferior phrenic artery, left gastric artery and right gastric artery. They branched to supply the upper segment and the inferior segment.Conclusion There are five types of hepatic arteries to supply the left liver lobe. The anatomy of hepatic arteries should be studied and a reasonable approach to gain a liver graft should be designed before transplantation. The hepatic arteries should be dealt with so as to anastomose with recipient hepatic arteries.
Objective To investigate the clinical choice on graft size and the type of donor’s hepatectomy in adult living related partial liver transplantation. Methods The literatures in recent years on the donor’s evaluation, the size of liver grafts, the types of donor hepatectomy and safety of donor in adult living related partial liver transplantation were reviewed.Results The size of liver graft is a crucial factor related to the safety of donor and the prognosis of the recipient. GW/ESLW≥30%, GW/BW≥0.8% may be the lowest limits. Left lobe contained middle hepatic vein, extended left lobe with leftside caudle lobe, right lobe or extended right lobe contained middle hepatic vein may be the practical choice.Conclusion It is important to make a reasonable choice of liver graft according to the estimation of GW/ESLW or GW/BW, and the anatomy of liver in adult living related partial liver transplantation.
