Objective To investigate serum alpha2-Heremans-Schmid glycoprotein ( AHSG ) level and its relationship with associated clinical parameters in subjects with simple overweight and obesity. Methods Forty-nine subjects with obesity ( OB group) , 176 subjects with overweight ( OW group) , and 327 individuals with normal weight ( NW group) were randomly enrolled. The clinical data were collected and serum levels of AHSG and adiponectin ( APN) were determined by ELISA. The associations of serum AHSG level with other clinical parameters were assessed by Pearson correlation analysis and multiple linear regressive model. Results Serum AHSG levels were higher in OW and OB groups than that in NW group[(276. 30 and 302. 10 vs 241. 60)μg/ml], being especially higher in OB group (P<0. 05 or P<0. 01). Serum AHSG level in NW group was positively associated with fasting plasma glucose, homoeostasis model assessment of insulin resistance index, C-reactive protein (CRP), triglycerides, and free fatty acids ( FFA ) , but negatively associated with age and APN. In OW and OB groups, AHSG was also positively associated with body mass index, waist hip ratio(WHR), and low density lipoprotein cholesterol(P<0. 05 or P<0. 01) except the aforementioned clinical parameters. In multiple linear regression model, AHSG was positively associated with WHR, CRP, and FFA, and was negatively associated with APN ( P<0. 05 or P<0. 01). Conclusion The raised AHSG level in overweight and obese subjects may be a risk factor for obesity-related diseases.

Objective To investigate the indications, techniques and results of laparoscopic hepatectomy. Methods The clinical data and follow-up results of 463 patients who received laparoscopic hepatectomy at our institute were retrospectively analyzed. Results From March 1, 2007 to March 31, 2011, 463 cases of laparoscopic hepatectomy were successfully carried out. Of the 463 patients,165 were with primary liver cancer, 29 with metastatic liver cancer, 143 with hepatic hemangioma, 81with hepatolithiasis and 45 with other benign liver diseases (including hepatic angiomyolipoma, hepatocellular adenoma, focal nodular hyperplasia and chronic liver abscess). The surgical approaches included laparoscopic left lateral lobectomy (93 cases), left hepatectomy (71 cases), extended left hepatectomy (4 cases), right hepatectomy (29 cases), right posterior lobectomy (24 cases), hepatectomy of segment Ⅵ (56 cases), extended right hepatectomy (2 cases), central hepatectomy (8 cases) and hepatectomy of segments Ⅶ/Ⅷ, Ⅳa, caudate lobe and the junction of segment Ⅵ and Ⅶ (41 case).Nonanntomic and wedge resection were performed on 121 patients, and combined resection on 14 patients. The mean operation time, blood loss, length of hospital stay and incidence of postoperative complications were (244.71 ± 105. 07) minutes, (460. 26±425.81) ml, (15.51 ±4.36) days and 9.29%, respectively. And no operative death occurred. In the 194 cases with malignant liver lesions,185 cases were followed up for 2 to 50 months. The 1 year and 3 year overall and disease free survival rate were 90. 8% and 87.9% , 84.2% and 73. 7% respectively. Conclusions As a means of minimally invasive surgical approach, laparoscopic hepatectomy can be selectively adopted for the treatment of all kinds of liver diseases which located at different parts of the liver, with the advantages of smaller trauma, quick recovery and cosmetic benefits. The short-term results of laparoscopic hepatectomy is superior to and its long-term results is equal to that of open surgery. Benign liver diseases, small hepatocellular carcinoma and metastatic liver cancer are the good indications for laparoscopic hepatectomy.

ObjectiveTo investigate the efficacy of laparoscopic hepatectomy for regional hepatolithiasis.MethodsThe clinical data of 81 patients with regional hepatolithiasis who received laparoscopic hepatectomy at the Southwest Hospital from March 2007 to March 2011 were retrospectively analyzed.Based on the classification of the Guideline for the diagnosis and treatment of hepatolithiasis 2007 version and indications for open surgery,hepatic lobes with calculi,biliary stricture or dilated bile ducts were resected laparoscopically after preoperative examination.Bile ducts of the remnant hepatic lobes were explored using fiber choledochoscope or electronic choledochoscope for the prevention of residual stones. Results Laparoscopic hepatectomy was successfully performed on 72 patients,and the other 9 patients were converted to open surgery. Left lateral lobectomy ( segments Ⅱ,Ⅲ ) was performed on 20 patients,left hemihepatectomy ( segments Ⅱ,Ⅲ,Ⅳ ) on 30 patients,right posterior lobectomy ( segments Ⅵ,Ⅶ ) on 11 patients,right anterior lobectomy ( segments Ⅴ,Ⅷ ) on 6patients,right hemihepateetomy (segments Ⅴ,Ⅵ,Ⅶ,Ⅷ ) on 9 patients,hepatic Ⅲ segmentectomy on 2 patients and hepatic Ⅵ segmentectomy on 3 patients.Gallbladders were resected,and intermittent portal triad clamping was performed on 15 patients.Hepateetomy combined with biliary exploration and stone removal was performed on 57 patients.The mean operation time and operative blood loss were (328 ± 80)minutes and (451 ±288) ml,respectively.No operative mortality was observed.Sixteen patients had postoperative complications,including pulmonary infection in 2 patients,pleural effusion in 4 patients,encapsulated effusion in the resection margin in 6 patients,abdominal infection and abscess in 2 patients and wound infection in 2 patients.Of the 16patients with complications,9 were cured by medicine,6 by pleural or abdominal drainage and 1 by wound debridement.The mean duration of hospital stay was ( 13 + 6)days.The intraoperative stone clearance rate was 96% (69/72),and the residual stone in 3 patients were removed by choledochoscopy.Sixty-nine patients were followed up for 7-55 months,7 patients had symptoms of cholangitis and 2 patients had common bile duct stone recurrence.ConclusionsLaparoscopie hepatectomy is sate and effective for regional hepatolithiasis.Accurate positioning of the stones and lesions pre- and intra-operatively,reasonable designing of the parenchymal transection plane,and anatomical liver resection are the key points for achiving good therapeutic effects.

Objective To investigate the effects of Pseudomonas aeruginosa vaccine (PA) on proliferation and invasiveness of the hepatocellular carcinoma cell line MHCC97L with metastatic potential. Methods Proliferation, growth curve, plate efficiency, flow cytometry, transwell invasion assay, cell motility assay, scarification test, vascular endothelial growth factor (VEGF) and matrix metalloproteinase-2 (MMP2) protein activity were evaluated after cells were treated with PA at various concentrations. Results PA can inhibit the proliferation and plate efficiency of MHCC97L cell markedly in a dose-dependent manner. The IC50 of cells treated with PA for 48 h and 72 h was 3.1 ×108/ml and 1.9 × 108/ml, respectively. The doubling time increased and plate efficiency decreased gradually when cells treated with 0.5 × 108/ml, 1 × 108/ml and 2 × 108/ml PA (P<0.01). PA could induce cell cycle arrest at the G1 phase in a dose-dependent manner by flow cytometric analysis. The average amount of invading cell per field in cell invasion assay and motility assay were 4. 8 ± 1.3 and 8. 8±2.2 when cells treated with 1× 108/ml PA, which was significantly lower than that of control group (8. 6±2. 1 and 15. 6±1.2 ) (P<0.01) Scarification test showed that the metastatic ability of cells treated with 1 × 108/ml PA significantly lower than that in the control group. Comparison between cells treated with 1 × 108/ml PA and control group, no remarkable difference was found regarding expression of VEGF and MMP2 in supernatant of cell culture. Conclusion PA can inhibit proliferation and plate efficiency of HCC cell line MHCC97L, which is in part mediated by the cell cycle arrest at the G1 phase. PA could inhibit invasiveness of HCC cell line MHCC97L, which is unrelated to the VEGF and MMP2 protein activity.

BACKGROUND: Simultaneous pancreas and kidney transplantation (SPK) has been considered an effective therapeutic means of diabetes mellitus (including type 1 and type 2) combined with end stage uremia. Because the pancreas possesses high immunogenicity, so a feasible immunosuppressive regimen is a key to successful pancreas transplantation. OBJECTIVE: To investigate the feasible immunosuppressive regimen after simultaneous pancreas and kidney transplantation (SPK). METHODS: From January 2005 to June 2009, 9 patients with diabetic nephropathy and end stage uremia, consisting of 5 males and 4 females, received SPK. The pancreatic allograft exocrine secretion was drained into the proximal jejunum via a side-to-side duodenojujunostomy. Quadruple immunosuppressive regimen including induction of interleukin-2 receptor monoclonal antibody, tacrolimus, mycophenolate mofetil and steroid, and gradual tacrolimus monotherapy. The clinical data of the 9 patients were analyzed retrospectively. RESULTS AND CONCLUSION: SPK was successfully applied to all patients without serious surgical complications such as pancreatitis, graft dysfunction and pancreatic fistula. One patient died of cardiovascular accident in the early stage after SPK. The other 8 patients were followed up for 4-50 months. Serum creatinine decreased to normal range within 1 week after surgery. The 8 patients achieved euglycemia during early postoperative stage with insulin independence time (11.5±3.5) days and with fasting blood glucose recovery time (15.4±6.3) days. Acute rejection of the renal graft occurred in 4 patients, 1 patient died of cardiovascular accident and the other 3 recovered after antihuman thymocyte globulin or steroids bolus treatment. No rejection was noted in pancreatic grafts. These findings indicate that SPK is an effective treatment for patients with diabetes mellitus-related middle- and end-stage uremia.Quadruple immunosuppressive regime including interleukin-2 receptor monoclonal antibody induction is feasible after SPK, and such a regimen can be safely converted to tacrolimus monotherapy.
