Objective: To construct a lentiviral vector of RNA interference(RNAi) of TGF-?1 gene. Methods: Three target sequences were selected according to TGF?1 mRNA sequence firstly,then three pairs of oligonucleotide sequences according to these target sequences and one pair of negative control oligonucleotide sequence were designed and synthesized. The annealed oligonucleotide fragments were subcloned into pRNA-U6/Lenti plasmid. After identified by restriction enzyme digestion and sequencing ,these plasmids were cotransfected along with ViraPowerTM Lentiviral Packaging Mix into 293FT cells for the package of lentiviral particles. Then the lentiviral vector particles were transfected into Hela cells and TGF-?1 expression in the transfected cells was assayed by Real-Time PCR and ELISA. Results: It was confirmed by digestion and sequencing that lentiviral vectors had the correct structure and could express high titer of virus. After transfected into Hela cells,TGF-?1 expression was decreased significantly by two of these lentiviral vectors at both the protein and mRNA level and the first vector had the best interefence efficiency. Conclusion: The lentivirus RNAi vector of TGF-?1 was constructed successfully.

Objective To explore the feasibility and value of ultrasonography during choledocholithotomy with fibroptic choledochoscope. Methods Fifty-one cases of intrahepatic bile duct stones after cholecystomsy as diagnosed by pre-operative examination with ultrasound, CT, magnetic resonance imaging from Jan. 2007 to Dec. 2008, underwent conventional lithotomy through fibroptic choledochoscope first, and then high-frequency probing with ultrasonography was done directly over the surface of liver to detect the existence of any residual stone in the bile duct. The position of residual stone, if there was any, was then accurately determined and removed through fibroptic choledochoscope under the guidance of ultrasonography. Results Of 51 patients who had undergone lithotomy through fibroptic choledochoscope, 12 patients were found to have residual stones in their bile ducts after operation. The rate of complete calculus removal was 76.5%, and of residual stones was 23.5%. Of the 12 patients with residual stones, 7 patients were found to have residual stones in their intrahepatic bile ducts complicated with deformed bile duct, 5 patients were found to have residual stones in their intrahepatic bile ducts complicated with stricture of bile duct. All residual stones in intrahepatic bile ducts of 12 patients were accurately located and then completely removed under the guidance of operative ultrasonography through fibroptic choedochoscope without any complications. Conclusions The difficulties of residual stones after lithotomy may be overcome by localization with ultrasonography and removal under the guidance of atfrasonography, so the technique is of practical value in clinical application.

Objective To evaluate the feasibility and value of percutaneous transhepatic multiple biliary drainage introduced under ultrasound guidance in treatment of advanced portal cholangiocarcinoma. Methods Thirty-two patients were accurately diagnosed as advanced portal cholangio carcinoma according to preoperational examination of ultrasound,enhanced computed tomography,nuclear magnetic resonance or endoscopic retrograde cholangiopancreatography (ERCP) in the hospital from Jan. 2006 to Dec. 2008. After making a reasonable therapeutic plan,3 or 4 drainage-tubes were successfully inserted in intrahepatic bile duct in turn using Seldinger technique under ultrasound guidance. Thus,retained bile was effectively drained from intrahepatic bile ducts. The changes in jaundice index after treatment and complications were observed,follow-up was performed during the patients' surviving period,and therapeutic effect was evaluated comprehensively. Results Of the 32 patients drained through multiple bile drainage-tubes,19 received 3 draining tubes simultaneously,and 13 with 4 bile drainage-tubes,with a total of 109 bile drainage-tubes inserted into all the patients. Bile drainage-tubes were inserted into all target bile ducts successfully in a 100% successful rate. 4-8 weeks after operation,the jaundice disappeared completely in 28 cases and decreased significantly in 4 cases. For all the cases,complication occurred in only 2 patients,and it disappeared after symptomatic treatment. The shortest survival time was 4 months,and the longest was for 15 months after operation. Conclusions For those patients with advanced portal cholangiocarcinoma,and the tumor could not be surgically resected,percutaneous transhepatic multiple biliary drainage is correct option,which is effective and safe,and it was valuable in relieving malignant obstructive jaundice.
