Objective To evaluate the feasibility and safety of laparoscopic right hemihepatectomy under selective hemihepatic inflow occlusion.Methods In performing this procedure,first dissect the right hepatic portal,and under selective hemihepatic inflow occlusion,laparoscopie Peng's multifunctional operative dissector (LPMOD) was used to transect the hepatic parenchyma by stepwise curettage and aspiration.Results Procedures were successful in all six patients of benign liver diseases,though a small subcostal auxiliary incision was needed in one case to control the middle hepatic vein branch hemorrhage.Operation time was 300-540 min[mean,( 399 ± 75 ) min].The time of hepatic portal dissect was 30-75 min[mean,(51 ± 16) min].The time of liver parenchyma transection was 60-160 min[mean,( 116 ± 32) min].Intraoperative blood loss was 600-3000 ml[mean,( 1486 ± 809 ) ml].The level of ALT increased to (302-557) U/L[mean,(386 ± 85 ) U/L]after the operation,and back to normal level in 5-11 d[mean,( 7.1 ± 2.0) d].The postoperative hospital stay was 10-18 d[mean,( 12.4 ± 2.6 ) d].No severe complication occurred after the operation.Conclusions Laparoscopic right hemihepatectomy under selective hemihepatic inflow occlusion is safe and feasible.

Objective:To research the influence and mechanism of Toufeng capsule (TFC) on the concentratioin of blood active substance and single amine neurotransmitter in the brain and blood of magraine mice.Methods: We chose animal disease model of migraine made by hypodermic nitroglycerin and measured the concentration of 5 HT. NE and DA in the rat's brain and blood by means of enzymeimmunoassay experimental methods.Results: TFC could obviously increase the concentration of 5 HT and NE in the bloold and of 5 HT, DA and NE in the brain.Conclusions: TFC might improve neurosystematic regulation functions and enhance the neurotransmitters' secretion and metabolism.

Objective To study the safety and feasibility of laparoscopic left lateral sectionectomy using the Glissonian pedicel approach.Methods The root of the round ligament of the liver was exposed and the Glissonian pedicel of the left lateral section was dissected,starting from left and using the lapa roscopic Peng's multifunctional operative dissector (LPMOD).After the Glissonian pedicel of segment Ⅱ and Ⅲ was dissected,clipped and cut,the ischemic boundary showed up.The liver was transected at the boundary of the ischemic liver,and the left hepatic vein and its branches were cut. Resutts The surgery was successtully performed in 8 patients.There was no conversion to open operation.The operative time was 110- 190 (151.0±35.4) min.The time of Glissonian pedicel dissection and liver resection was 70- 135 (101.0±24.1) min.Operative blood loss was 100-300(210.0± 89.4) ml.The ALT increased by 35- 102 (75.4± 26.5) U/L after operation and decreased to a normal level in 2-6 (3.0± 1.7) d.The postoperative hospital stay was 6-10 (8.2± 1.6) d.There was no major complication.Conclusion Laparoscopic left lateral sectionectomy using the Glissonian pedicel approach is safe and feasible.
