Objective To evaluate the safety and feasibility of laparoscopic left hepatectomy in patients with primary hepatic carcinoma. Methods Retrospective analysis was conducted in clinical data of left hepatectomy from 2007 to 2014,including 47 cases of laparoscopic hepatectomy and 46 cases of open hepatectomy. The intraoperative and postoperative data of the two surgical methods were compared to evalu-ate whether laparoscopic left hepatectomy is safe and feasible. Results The tumor size were bigger in the open hepatectomy [(56. 57 ± 24. 56) mm vs. (64. 11 ± 33. 39) mm,P=0. 218]. The laparoscopic left hepatectomy resulted in shorter operation time [(217. 53 ± 60. 22) min vs.(306.80±119.91)min],andtherewasasignificantlydifference(P<0.05).Theintraoperativebloodlosswerelesserinthelaparo-scopic left hepatectomy [(350. 21 ± 197. 98) mL vs. (556. 74 ± 471. 41) mL],and there was a significantly difference (P<0. 05). The lap-aroscopic left hepatectomy had a smaller intraoperative blood transfusion rate (12. 8% vs. 32. 6%,P<0. 05). The length of ICU stay,time for gastroentestinal function recovery, postopetative hospital stay were shorter than those of open left hepatectomy (P<0. 05). There was no significant difference of postoperative complication rate between them (14. 9% vs. 23. 9%,P=0. 271). The survival rates of 1-and 3-year after operation in patients with laparoscopic left hepatectomy were 91. 5% and 83. 0% respectively,while 84. 8% and 76. 1% in patients un-derwent open hepatectomy. The tumor-free survival rates 1-and 3-year after operation were 74. 5% and 59. 6% in patients with laparoscopic left hepatectomy respectively,while 65. 2% and 54. 3% in patients underwent open hepatectomy. Conclusion Laparoscopic left hepatectomy for primary hepatic carcinoma is safe and feasible. Laparoscopic left hepatectomy could be a consideration as the standard surgical methods for hepatic carcinoma.

Objective To probe the relationship between the patients′ prognosis and the gene of multidrugs and drug resistance in uveal melanoma. Methods The gene expression of cyclin D1, epithelial growth factor receptor (EGFR), non metastasis gene 23 (nm 23), P glucose protein (P gp), multidrug resistance relation protein (MRP) and lung resistance protein (LRP) expression in 96 cases of uveal melanoma were detected by depigment immunohistochemistry. The patients with complete anamnesis data were observed continuously, and the follow up results were classified. Results Among the 96 cases of uveal melanoma, the epithelioid cell type was in 21, the mixed cell type in 56, and the spindle cell type in 19; including 76 at intraocular stage and 20 at extraocular stage. As the level of metastasis suppress gene nm 23 expression decreased and the level of cyclin D1 and EGFR expression increased, the expression level of drug resistance genes increased. The levels of LRP and MRP had negative correlation to the expressions of nm 23 and postive correlation to the expressions of nm 23, Cyclin D1 and EGFR. In 58 patients′ who were observed continuously, 19 died in 5 years and 26 survived over 5 years. Conclusion There are significant association between patients′ prognosis and multidrug and drug resistance gene in uveal melanoma.

Objective To investigate the impact of reduced glutathione(GSH) on the prolifera- tion,oxidative stress and transforming growth factor?1(TGF-?1) expression of human hepatocytes and hepatic stellate cells(HSCs)(LX-2 cell line).Methods Human hepatocytes and HSCs were incubated with various concentrations of GSH(0.5—50 mmol/L or 0.5—10 mmol/L).The effects of GSH on the proliferation of hepatocytes and HSCs were studied by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphennyhera- zolium bromide colorimetric assay.Human hepatocytes and HSCs were co-cultured with GSH and ferric nitrilotriacetic acid,superoxide dismutase (SOD) activity and malondialdehyde (MDA) contents were detected.HSCs were incubated with high(5.0 mmol/L),media(2.5 mmol/L) and low (0.5 mmol/L) concentrations of GSH,the expressions of TGF-?1 mRNA and protein were detected by ELISA and real- time PCR.Results In concentration ranged from 2.5 to 10 mmol/L,the GSH could promote the pro- liferation of hepatocytes but no HSCs,significantly increased the activity of SOD and decrease the con- tents of MDA in hepatocytes and HSCs,and inhibited the expression of TGF-?1 in HSCs.Conclusions GSH can not only promote the proliferation of hepatocytes,but also protect hepatocytes and HSCs from oxidative stress,and inhibit the secretion of TGF-?1 in HSCs.GSH may play a role in hepatocellular protection,antioxidation and anti-fibrosis.

AIMTo examine the liver mechanism with which clenbuterol (CL) is explained how to affect growth metabolism.

METHODSThe technique of chronic poly catheter was used to study the effects of CL (0.8 mg/kg b w) on the hepatic flux of nitrogen, VFA and glucose in 4 sheep.

RESULTSThe urea-nitrogen flux in CL-treated period always was lower than that in control during 24 h. The average flux of urea-nitrogen in hepatic and portal vein were decreased by 16.86% (P < 0.01) and 15.51% (P < 0.05), respectively, compared with that of control. The peptide level in hepatic vein was decreased with the treatment of CL, average flux of peptide was decreased by 38.71% (P < 0.01). But the peptide level of portal vein in CL treatment period was similar to control. Moreover, VFA level in the portal vein was enhanced by CL, the average flux of acetate in portal vein was increased by 19.49% (P < 0.01). No difference of VFA level in hepatic vein was noted between CL-treated period and control. In addition, the glucose flux in hepatic vein was obviously increased with CL treatment, the average flux of glucose was increased by 25.96% (P < 0.01). And glucose flux in portal vein was also elevated during CL-treated period.

CONCLUSIONCL can affect growth metabolism of animal with increasing nitrogen deposition, improving absorption and utilization of VFA and enhancing glucose synthesis in sheep liver.

Despite recent advances in conventional therapeutic approaches for cancer, the efficacy of chemotherapy for cancer is limited due to the drug resistance and toxic side effects during treatment. To overcome drug resistance, higher doses of the toxic chemotherapy drugs are frequently administered, thus leading to even severe adverse side effects, which have limited their clinical application. Cationic liposome as a novel non-viral carrier for co-delivery of gene and chemotherapy drugs in cancer gene therapy has already attracted more and more attention in recent years. Most importantly, this combined strategy can generate a significant synergistic effect, which can silence the related gene expression and increase the concentration of the intracellular chemotherapy drugs. This approach allows the use of a much lower dose of the chemotherapy drugs to achieve same therapeutic effect, which may have the potential for overcoming some major limitations of the conventional chemotherapy. In conclusion, co-delivery of gene and chemotherapy drugs with cationic liposome delivery system will play a vital role in the future and especially could be a promising clinical treatment for drug-resistant tumors.

OBJECTIVETo study the pathological features of uveal melanoma and to evaluate their influence on patients' prognosis.

METHODSParaffin embedded uveal melanoma tissues of 115 cases were examined using routine pathologic methods. Three histological types were classified according to the modified Callender system and patients were followed clinically. The data were done regression and survival analysis by SPSS statistic soft.

RESULTSThe patient with epithelial cell type, mixed type, and spindle cell type uveal melanoma have different life times, the average life time is 35.6 +/- 21.5 months, 63.7 +/- 37.0 months, 69.5 +/- 36.5 months in turn, patients with epithelial uveal melanoma had shorter survival time than other two types. The survival time was negatively related to the largest diameter of contact area with the sclera, the largest height and the depth of tumor invasion to the sclera.

CONCLUSIONSEpithelial uveal melanoma is more malignant than the other two types. Histological classification of this tumor combined with other pathologic features can indicate the patient's prognosis.

OBJECTIVETo explore liver X receptor alpha (LXR alpha) gene changes and their significance in nonalcoholic fatty liver disease (NAFLD) in rats.

METHODSA rat model of nonalcoholic fatty liver disease was produced with a fatty diet regime (feeding group, FG). Rats fed with normal diet served as controls (CG). The mRNA and protein expressions of LXR alpha in liver tissues were detected by reverse transcription and polymerase chain reaction (RT-PCR) and Western blot.

RESULTSThe concentration of free fatty acid (FFA) in the sera of GF rats started to increase to 0.33 mmol/L after 4 weeks of fat diet feeding, while the FFA of the CG was just 0.24+/-0.03 mmol/L, and the difference was significant (P<0.05). The concentration of ALT and AST in sera of the FG rats started to increase to 75.8 U/L and 138.9 U/L at the 8th week, much higher than those of the CG (P<0.01), and at the 12th week they increased further (P<0.01). Meanwhile, the mRNA and protein expressions of LXR alpha at the 2nd week was significantly increased to 0.62 (P>0.01) and its peak was reached at the 12th week (P<0.01). There was a significant positive correlation between the expression of LXR alpha and the degree of NAFLD.

CONCLUSIONThe changes of LXR alpha gene are closely related to the development of nonalcoholic fatty liver disease.
