3.Radiofrequency ablation for the treatment of recurrent hepatocellular carcinoma:analysis of the therapeutic results and prognostic factors
Journal of Interventional Radiology 2015;(10):923-927
Based on both domestic and abroad research results concerning the local therapeutic efficacy, influence factors, survival time and prognosis of radiofrequency ablation (RFA) in treating recurrent hepatocellular carcinoma (HCC), this paper aims to make a review of medical literatures about RFA treatment of recurrent HCC that were published in Chinese and in English during the period from 2005 to 2014, and to analyze the related factors that may influence the local therapeutic efficacy and survival rate. The results indicate that the recurrent tumor size, tumor number, recurrence interval, serum alpha fetoprotein (AFP) level, serum prothrombin, etc. are important factors that will affect the therapeutic efficacy of recurrent HCC. At the same time, the results point out that the study of imaging predictors can help suggest the different recurrent types, which is very useful in making individualized follow-up strategy and in monitoring tumor recurrence. Local treatment, with RFA being the main method, together with comprehensive therapies, including other new technologies and new drugs, will improve the current clinical situation in treating recurrent HCC.

5.Analysis of Risk Factors of Recurrent Inguinal Hernia by Cox Proportional Hazard Regression Model
Chinese Journal of Bases and Clinics in General Surgery 2003;0(03):-
Objective To retrospectively analyze the risk factors of recurrent groin hernia. Methods Data came from all hernia repairs recorded in our hospital between 1991 and 2001. A total of 1 082 cases of groin hernia was analyzed through Cox proportional hazard model to determine the relative risks between recurrence and mode of admission, types of groin hernia, repair methods (traditional/tension free hernioplasty), and post operative complications.Results From 1991 to 2001,1 082 groin hernia operations were performed in our hospital, 88.9% for primary hernia and 11.2% for recurrent hernia. As compared with traditional hernia repair methods, Lichtenstein’s tension free hernioplasty technique had less relative risk for recurrent hernia repair than that for primary hernia repair. Postoperative complications and indirect hernia were linked to an increased relative risk for recurrence. Conclusion There are many factors affecting the recurrence of inguinal hernia, but the use of tension free hernia repair may decrease re recurrence of recurrent hernia.

8.Rearch and clinical application of materials to bile duct repair and reconstruction
Chinese Journal of General Surgery 1993;0(02):-
Objective To review experimental study and clinical application of materials to bile duct repair and reconstruction.Methods Comparison of different materials was made between advantages and disadvantages.Results Synthetic grafts such as vitallium,teflon are easy to handle,but have no flexion,and have foreign body reaction.Although autogenous free tissues such as venous patch and peritonium are resistant to infection,they are likley to lead to bile duct stricture because of lacking adeuqate blood supply.Vascularized neibouring tissues for repearing bile duct defect have satisfactory results.Conclusions To avoid bile duct striccture,vary measures should be taken to repair bile duct defecs;for segmental loss of bile duct,end to end anastomosis or Roux-en-Y biliary jejunal reconstruction should be applied.
9.Progress of tissue-engineered blood vessels
Chinese Journal of Tissue Engineering Research 2007;0(23):-
Vascular bypass grafting is the most common procedure for ischemic heart disease and peripheral vascular disease. Although synthetic grafts have been developed, replacement of vessels with purely synthetic polymeric conduits often leads to the failure of such graft, especially in the grafts less than 6 mm in diameter, mainly due to the early formation of thrombosis, infection and so on. Tissue engineering is a relatively new discipline that offers the potential to create vascular grafts from autologous cells and biodegradable polymer scaffolds. It has become a promising approach for generating a biocompatible vessel graft and contributing to the long-term patency rate of small-caliber grafts. This review describes the major progress in the tissue engineering vascular grafts, including the seeding cell sources, the biodegradable scaffolds, the construction technologies of tissue-engineered vessels, as well as nanotechnology.
