Objective To compare the outcomes of giant hepatic hemangioma undergoing enucleation and hepatectomy and to summarize our experience of surgical management of liver hemangioma.Methods A retrospective study was conducted in patients undergoing giant hepatic hemangioma resection (lager than 10 cm in size) in General Hospital of PLA,during 2006 through 2014.Patients were divided into two groups according to the types of operation.Results Of 145 patients with giant liver hemangioma,81 underwent enucleation and 64 had hepatectomy.The differences of tumor size (12.0 cm vs.15.5 cm,u =3.68,P ＜0.01),time of operation (210 min vs.280 min,u =3.89,P ＜ 0.01) and the ratio of inflow control (81.5％ vs.56.3％,x2 =10.91,P ＜ 0.01) of enucleation and hepatectomy was significant.The difference of intraoperative blood loss (500 ml vs.800 ml,u =1.85,P =0.07) and the postoperative morbidity (8.6％ vs.7.8％,x2=0.03,P =0.86) was not statistically significant.There was no inhospital mortality in both groups.Conclusions Both of enucleation and hepatectomy are effective operative approaches for giant liver hemangioma,patients with liver hemangioma should be prudently chosen for surgery,and the operation type should be individualized with the guidance of precision liver surgery.

Objective To explore the relationship between diameter of liver hemangioma and operation risk.Methods The clinical data of 362 patients with liver hemangioma who were admitted to the PLA General Hospital from January 2006 to January 2014 were retrospectively analyzed.All patients were divided into the 3 groups according to diameter of gross specimen,217 with tumor diameter≥5 cm and ≤ 10 cm in the large hemangioma group,119 with tumor diameter ＞ 10 cm and ≤20 cm in the giant hemangioma group and 26 with tumor diameter≥20 cm in the extremely large hemangioma group.The operation method included open surgery and laparoscopic surgery.Hepatectomy and enucleation of liver hemangioma were major operation procedures.The operation time,volume of intraoperative blood loss,number of patients with intraoperative blood transfusion,number of patients with postoperative complications and duration of hospital stay were evaluated.Count data were analyzed using the chi-square test.Measurement data with normal distribution were presented as (x) ± s,and comparison among groups was analyzed using the ANOVA.Skewed distribution data were described as M (P25,P75),comparison among groups was analyzed by Kruskal-wallis test and pairwise comparison was done by the MannWhitney U test.Results All patients underwent operation successfully without perioperative death,including 315 receiving open surgery (175 in the large hemangioma group,114 in the giant hemangioma group and 26 in the extremely large hemangioma group) and 47 receiving laparoscopic surgery (42 in the large hemangioma group and 5 in the giant hemangioma group).The operation time,volume of intraoperative blood loss,number of patients with blood transfusion,number of patients with postoperative complications and duration of hospital stay were 160 minutes (125 minutes,205 minutes),300 mL (100 mL,500 mL),31,5 and 8 days (7 days,9 days) in the large hemangioma group,220 minutes (175 minutes,275 minutes),500 mL (300 mL,1 000mL),36,5 and 9 days (8 days,10 days) in the giant hemangioma group,330 minutes (280 minutes,420 minutes),1 975 mL (800 mL,4 000mL),20,7 and 11 days (9 days,13 days) in the extremely large hemangioma group,respectively,with significant differences (x2 =84.24,80.94,53.65,31.54,47.67,P ＜ 0.05).The operation time,volume of intraoperative blood loss,number of patients with intraoperative blood transfusion and duration of hospital stay were compared,showing significant differences between large hemangioma group and giant hemangioma group (Z =6.39,6.51,x2 =11.29,Z =4.73,P ＜ 0.05),with significant differences between large hemangioma group and extremely large hemangioma group and between giant hemangioma group and extremely large hemangioma group (Z =7.28,6.91,x2=51.22,Z =5.57,P ＜ 0.05;Z =5.33,4.86,x2=17.69,Z =3.5 1,P ＜ 0.05).Seventeen patients had postoperative complications with an incidence of 4.70％ (17/362),intra-abdominal hemorrhage were detected in 7 patients,perihepatic effusion in 4 patients,pleural effusion in 3 patients,bile leakage in 2 patients and fat liquefaction of abdominal incision in 1 patient.There was no significant difference in the number of patients with postoperative complications between large hemangioma group and giant hemangioma group (x2 =0.41,P ＞ 0.05).There were significant differences in the number of patients with postoperative complications between large hemangioma group and extremely large hemangioma group and between giant hemangioma group and extremely large hemangioma group (x2 =24.96,11.67,P ＜ 0.05).Conclusions Diameber of liver hemangioma is associated with operation time,volume of intraoperative blood loss,number of patients with intraoperative blood transfusion,number of patients with postoperative complications and duration of hospital stay,and there is a high risk in the surgical treatment of patients with liver hemangioma diameter≥20 cm.

OBJECTIVETo develop a reserved-phase HPLC method for the determination of praeruptorin A, praeruptorin B, qianhucoumarin E in roots of Peucedanum praeruptorum.

METHODAgilent TC-C18 column (4.6 mm x 250 mm, 5 microm) was used at 30 degrees C with the mobile phase of methanol-water (75:25). The flow rate was set at 0.8 mL x min(-1). The detection wavelength was 321 nm.
