Objective To investigate the value of continuous occlusion of hepatic artery proper to intermittent Pringle maneuver in partial hepatectomy for ruptured hepatocellular carcinoma(HCC).Methods The clinical data of 36 patients(test group)who received partial hepatectomy for ruptured HCC by adding continuous occlusion of hepatic artery proper to intermittent Pringle maneuver at the Southwest Hospital were retrospectively analyzed.Thirty-six patients(control group)who received intermittent Pringle maneuver only were selected as the control.All data were analyzed using the chi-square test,Fisher exact probability and analysis of variance.Results The mean hepatic artery occlusion time of the test group was 58 minutes(range,36-98 minutes).The median blood loss of the test group was 400 ml,which was significantly less than 750 ml of the control group(F =16.47,P ＜ 0.05);78%(28/36)of patients in the test group did not receive blood transfusion,which was significantly more than 53%(19/36)of the control group(x2 =6.01,P ＜0.05).The levels of postoperative serumaspartate transaminase and total bilirubin of the 2 groups were peaked at postoperative day 2 and then decreased to the normal level 1 week later.There were no significant differences in the incidences and levels of complications between the 2 groups(x2 = 1.83,0.89,P ＞ 0.05).Conclusion The addition of continuous occlusion of hepatic artery proper to intermittent Pringle maneuver significantly reduces intraoperative blood loss and doesn't bring any adverse effects to hepatic function for partial hepatectomy in patients with ruptured HCC when compared with intermittent Pringle maneuver alone.

Fructose-1, 6-bisphosphatase (FBPase), a rate-limiting enzyme involved in the pathway of gluconeogenesis, can catalyze the hydrolysis of fructose-1, 6-bisphosphate to fructose-6-phosphate. Upon inhibiting the activity of FBPase, the production of endogenous glucose can be decreased and the level of blood glucose lowered. Therefore, inhibitors of FBPase are expected to be novel potential therapeutics for the treatment of type II diabetes. Recent research efforts were reviewed in the field of developing allosteric inhibitors interacting with the AMP binding site of FBPase.

Objective To evaluate the efficacy of mini-clamp crushing combined with saline-linked diathermy in hepatectomy for giant hepatocellular carcinoma(HCC).Methods The clinical data of 58 patients with giant HCC(diameter≥10 cm)who received hepatectomy with the mini-clamp crushing technique(miniclamp crushing group)at the Southwest Hospital from April 2006 to December 2009 were retrospectively analysed.According to the tumor size,location and Child classification,the clinical data of 58 patients with similar parameters and received hepatectomy with traditional clamp crushing technique(control group)were selected from the database to conduct the matched case-control study.All the peri-and postoperative data were compared and analysed via one-way ANOVA,chi-square test and Fisher's exact test.Results The median blood loss and transfusion of control group were 850 ml and 650 ml,which were significantly higher than 400 ml and 550 ml of mini-clamp crushing group(F=16.23,5.63,P＜0.05).Twenty-four patients in control group needed blood transfusion,which was significantly larger than 6 of mini-clamp crushing group(χ~2=14.57,P＜0.05).The median time for parenchymal transection and portal triad clamping of control group were 45 minutes and 16 minutes,which were significantly shorter than 86 minutes and 35 minutes of mini-clamp crushing group(F=12.76,11.23,P＜0.05).The numbers of patients in control group who had complications and blood loss were 43 and 28,which were significantly larger than 13 and 8 of mini-clamp crushing group(χ~2=18.69,16.11,P＜0.05).The numbers of patients who had bile leakage,encapsulated effusion of the liver cut face and hepatic insufficiency were 8,5 and 2 in control group,and were 2,3,0 in mini-clamp crushing group,with no significant difference(χ~2=3.04,0.54,2.04,P＞0.05).Conclusion Mini-clamp crushing combined with saline-linked diathermy for the treatment of g4ant HCC is mone effective and available than traditional clamp crushing in terms of reducing blood loss and complications.

As a method of choice in the treatment of ampulary carcinoma,pancreaticoduodenectomy often demands open procedure.With the development of minimally invasive techniques,laparoscopic pancreaticoduodenectomy was realized in recent years.Because laparoscopic pancreaticoduodenectomy is high technique-demanding,its popularization is restricted.With flexible robotic arnls and three-dimensional imaging,Da Vinci surgical system has overcome the shortcomings of traditional laparoscope to some extent.In March 2010.a 60-year-old female patient with ampulary carcinoma underwent Da Vinci surgical system-assisted pancreaticoduodenectomy at the Southwest Hospital.The mean operation time and blood loss were 490 minutes and 450 ml respectively,and no blood transfusion was required.Out-of-bed activity began shortly after the operation.The gastric tube was removed and fluid diet was given on postoperative day 3.The patient was discharged on postoperative day 10 without incidence of complications.The Success of this case preliminarily demonstrats that Da Vinci snrgical system-assisted pancreaticoduodenectomy is safe and feasible.
