The postoperative hospital stay averaged at 5.7 days. No complications occurred. Conclusion Based on these preliminary results, we conclude that laparoscopic anatomical left lateral lobectomy can be carried out safely and effectively by a surgeon with the sufficient expertise of laparoscopy and hepatobiliary surgery.

Objective To discuss the application of microsurgery in the treatment of male infertility.Methods From March 2007 to March 2012,there were totally 853 infertile men received microsurgical treatments in our department.Among them,344 patients with unilateral or bilateral varicocele underwent microsurgical varicocelectomy,60 underwent vasovasostomy (VV) and 192 underwent vastoepidystomy (VE)in microsurgical methods due to obstructive azoospermia.257 non-obstructive azoospermia (NOA) patients were performed microdissection of testicular sperm extraction (MD-TESE),at the same time,pathologic examination was done.Results ①For the varicocele patients,the pre-operative sperm density was (10 ±6) × 106/ml,the progressive sperm percentage was (16 ± 9)％.The post-operative density was (15 ± 8) ×106/ml,the progressive sperm percentage was (28 ± 14)％.The natural pregnant rate was 10.8％ (37/344).②In 60 patients undergone VV,the patent rate was 80.0％ (48/60),the natural pregnant rate was 35.0％ (21/60).In 192 VE patients,the patent rate was 53.1％ (102/192),the natural pregnant rate was 19.8％ (38/192).③In 257 NOA patients,the testicular volume,sperm retrieval rate of MD-TESE was significantly higher than that of conventional testicular sperm extraction (60.3％ vs.38.1％).Conclusion The microsurgery techniques in male infertility treatments could have some advantages such as explicit effects and decreased injuries.

Objective:To study the possible immune escape mechanisms of HCoV-OC43 from human dendritic cells(DC).Methods:HCoV-OC43 was isolated from clinical specimen using BSC-1 cells and identified by Real-time PCR,and the cytopathic effect was observed by phase contrast microscope.DCs were induced in vivo using hu-GM-CSF and IL-4 cytokines,and after 7 days of differentiation,DCs were infected by HCoV-OC43.The morphology of HCoV-OC43 infected DC was observed by transmission electron microscope,and the cytokines related to DC functions were detected by Real-time PCR after infection.DC proportion and function related co-stimulatory molecules were analyzed by flow cytometry.Results:In vitro HCoV-OC43 infected human DC model was successfully built.HCoV-OC43 can infect DC and generate immune response of DC in vitro,but no virus nucleonic acid could be detected in culture supernatant.The DC expression of IFN-α,IFN-β,CCL3 and CCL5 were significant decreased when infected with HCoV-OC43,but the expression of costimulatory molecules including HLA-DR,CD1c and CD86 were not affected by HCoV-OC43 infection.Conclusion:Human DC could be infected by HCoV-OC43 and generate immune response,but could not produce progeny virus.HCoV-OC43 may escape from immune response by suppressing the expression of IFN-α and other inflammatory cytokines and chemokines in DC.

AIM: To study the renoprotective and synergistic effects of sesamin in combination with vitamin E on nephropathy in rats with the metabolic syndrome.METHODS: Nephropathy of metabolic syndrome in rats was induced by high-fat and high-carbohydrate diet.Sesamin(30 mg?kg-1?d-1),sesamin +vitamin E [(15+20) mg?kg-1?d-1),sesamin +vitamin E(30+20) mg?kg-1?d-1] and vitamin E(20 mg?kg-1?d-1) were given to rats with metabolic syndrome at 9th week and lasted for 16 weeks.After 24 weeks,the body weight,left kidney humid weight,blood glucose(BG),blood lipids(BL),systolic blood pressure(SBP), renal function,and indexes of oxygenation and antioxygenation for renal cortex were measured.Pathological changes,collagen deposition and iNOS protein and nitrotyrosine expression of kidney were observed by HE-stain,Masson-stain and immunohistochemical method,respectively.RESULTS:(1)In high-fat and refined-sugar diet group(HFS): the levels of BG,BL,SBP,and MDA,OH and NO2-/NO3-in renal cortex were increased;the activities of T-SOD, CAT and GSH-Px in renal cortex were decreased;the expressions of iNOS protein and nitrotyrosine in kidney were up-regulated;the inflammatory cell infiltration and collagen deposition in renal glomerulus and renal interstitium were severe;the glomerular sclerosis and renal interstitial fibrosis were obvious;the renal function was deteriorated.(2)In sesamin +vitamin E [(30+20) mg?kg-1?d-1] group: the decreases in BG,BL,SBP,MDA,OH-and NO2/NO3-in renal cortex were obviously observed;the activities of T-SOD,CAT and GSH-Px in renal cortex were increased;the expressions of iNOS protein and nitrotyrosine in kidney were down-regulated;the inflammatory cell infiltration and collagen deposition in renal glomerulus and renal interstitium were improved;the glomerular sclerosis and renal interstitial fibrosis were reversed;the renal function was ameliorated.The therapeutic effect of sesamin +vitamin E[ (30+20) mg?kg-1?d-1] surpassed that of using sesamin or vitamin E alone(P

Objective: To analyze the therapeutic effect of repeated hepatectomy on recurrent hepatocellu-lar carcinoma and prognostic factors. Methods: We retrospectively analyzed the clinicopathologic data of 48 patients who underwent repeated hepatectomy for recurrent hepatocellular carcinoma between July 1995 and July 2003. Overall survival rate and disease-free survival (DFS) rate were calculated by Kaplan-Meier meth-od. Prognostic factors were analyzed by univariate and multivariate analysis. Results: The median survival of 48 patients was 36.4 months. The overall 1-, 3-, and 5-year survival rates were 81.3%, 45.8%, and 27.1%, re-spectively. The disease-free 1-, 3-, and 5-year survival rates were 70.8%, 25.0%, and 16.7%, respectively. Univariate analysis showed that TNM stage of primary tumor, TNM stage of the recurrent tumor, vascular in-vasion, recurrent tumor size (>5cm) and recurrence-free interval were prognostic risk factors for overall surviv-al. While TNM stage of primary tumor, recurrent tumor size (>5cm), TNM stage of recurrent tumor, vascular in-vasion, pathological grading of recurrent tumor, preoperative AFP and recurrence-free interval were prognos-tic risk factors for DFS. Multivariate analysis showed that recurrence-free interval and TNM stage of recurrent tumor were independent prognostic risk factors for overall survival. While recurrence-frae interval and recur-rent tumor size (>5cm) were independent prognostic risk factors for DFS. Conclusion: Short recurrence-free in-terval (≤24 months), recurrent tumor size (>5cm) and TNM stage of recurrent tumor indicate poor prognosis of patients who received repeated hepatectomy for recurrent hepatocellular carcinoma.

Objective This study is to explore the expression of CIP2A mRNA in hepatocellular carcinoma (HCC), and its correlations with clinicopathologic features and prognosis of HCC patients.Methods CIP2A mRNA expression was analyzed in four liver cancer cell lines (Hep-G2, MHCC97,SMMC-7721 and BEI-7402), one immortalized liver cell line L-O2, neoplastic tissues and adjacent matched non-neoplastic liver tissues in 120 HCC patients and normal liver tissues of 20 cases using semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). The correlations between CIP2A mRNA and clinicopathologic features and prognosis of HCC were analyzed. Results CIP2A mRNA was detected in Hep-G2, MHCC-97H, SMMC-7721 and BEL-7402, but not in L-O2.The positive rate of CIP2A mRNA expression was significantly increased in HCC tissues (78.3%)than in adjacent matched non-neoplastic liver tissues (28.3%) and normal liver tissues (5.0%,P＜0. 01). CIP2A mRNA expression was correlated with tumor size, differentiation and TNM stage (P＜0.05). Patients with positive expression of CIP2A mRNA had lower overall survival and diseasefree survival rates. Conclusions CIP2A mRNA, which is highly expressed in liver cancer cell lines and HCC tissues, may be involved in hepatocarcinogenesis. CIP2A mRNA may be a valuable biomarker for assessing the prognosis of HCC.
