  • The Clinical Study of Using Modified Glisson Pedicle Transection Method in The Precise Hepatectomy of Hepatocellular Carcinoma

    Objective To explore the safety and feasibility of using modified Glisson pedicle transection methodin the precise hepatectomy of hepatocellular carcinoma (HCC). Methods Sixty patients with HCC, which confirmed by postoperational pathology were admitted in the study. During the surgery of experimental group (Glisson group), the segment pedicle were transected firstly using modified Glisson pedicle transection method. Then, the liver parenchyma was split follow the hepatic vein guided by intraoperative ultrasound. During the surgery of contrast group (Prigle group),the liver parenchyma was split using ultracision harmonic scalpel under intermittent pringle clamping of hilar. Results There were no significant difference in the amount of intraoperative bleeding, blood transfusion, as well as duration of surgery, serum alanine aminotransferase, total bilirubin, and length of hospital stay between the two groups (P>0.05). However, the incidence of postoperative complication was lower in Glisson group (23.3% vs. 50.0%, P<0.05). In addition, the length of tumor margin was more favorable in Glisson group 〔(2.3±0.7) cm vs. (1.5±0.6) cm, P<0.05〕. The recurrence rate of Glisson group was lower than that Prigle group, but was not different significantly (P>0.05). Conclusions The modified Glisson pedicle transection method has the same safety as traditional method in the precise hepatectomy of HCC. And it has the advantages in lower postoperative complication and more favorable tumor margin, which may reduce the recurrence rate theoretically.

  • Expression and Function of CD105 in Angiogenesis

    Objective To develop an in vitro three-dimensional angiogenesis system and analyze the expression and function of CD105 in angiogenesis. Methods After primary human umbilical vein endothelial cells (HUVEC) were purified and cultured, the microcarriers were coated with HUVEC and then embedded and cultured into fibrin gel. The angiogenesis process of HUVEC on the microcarriers was formed. The expression of CD105 during this process was detected by reverse transcription polymerase chain reaction (RT-PCR). Antisense oligodeoxynucleotide (ASODN) was used to inhibit the expression of CD105 and the changes of the angiogenesis process were analyzed quantitatively. Results HUVEC on the microcarriers which were embedded into the fibrin gel, occurred the angiogenesis process of sprouts, branches and capillary networks with lumina. During this process, CD105 was over expressed in the periods of forming sprouts and branches, and depressed in the relatively steady periods including the periods before forming sprouts and after forming capillary networks. While the expression of CD105 was inhibited by ASODN, the angiogenesis process was significantly inhibited. Conclusions The expression of CD105 is varied within the angiogenesis process, over expressing during the sprouts and branches forming periods. Inhibiting the expression of CD105 could efficiently inhibit angiogenesis.
