im To study the structure-function relationship of hTNFα . Methods We compared the cytotoxicity, receptor binding ability and toxicity in animal body of wild type(wt)hTNFα with its mutants including R2K-, N30S-, R32W-, L157F-hTNFα , and two multi-site mutants(R32W-L157F-hTNFα and R2K-N30S-R32W-L157F-hTNFα ). Results We found that the two multi-site mutants remained similar cytotoxicity to several human tumor cell lines as wild type hTNFα . However, their cytotoxicity to L929 cells were decreased sharply as compared with those of wt hTNFα . The two multi-site hTNFα mutants had lower binding activity with hTR75 than hTR55. We also found that compared with the wild type, the LD50 of the mutant R32W-L157F-hTNFα was decreased about 300 fold and the dose of mutant R2K-N30S-R32W-L157F-hTNFα resulted in 30％ death was 700 folds lower than LD50 of wt hTNFα . To certify the systematic toxicity of the mutant R2K-N30S-R32W-L157F-hTNFα , we assayed its toxicity to monkeys and found that its systematic toxicity was lower than that of wt hTNFα. Conclusion A 4-site mutants(R2k-N30S-R32W-L157F-hTNFα )of hTNFα is obtained, which the mutant may possess potential application value in clinical therapy.

Objective To investigate the clinical value of medical image-three dimensional visible system (MI-3DVS) in percutaneous transhepatic cholangioscopy lithotripsy (PTCSL) for the treatment of hepatolithiasis.Methods The clinical data of 66 patients with hepatolithiasis (55 were from the First People's Hospital of Shunde City and 11 were from the Zhujiang Hospital) were retrospectively analyzed.The images of computed tomography were three-dimensionally reconstructed with MI-3DVS.The location,number,size,shape of the stones were figured out,and the operation strategies of PTCSL were designed according to the types of the disease.The clinical value of MI-3DVS was evaluated according to the operation results and postoperative recovery of patients.All the patients were followed up via telephone or out-patient re-examination.Results Liver,biliary system,stones and blood vessels were three-dimensionally reconstructed with the MI-3 DVS,and the size,number,shape,location of the stones and location,degree,length of the biliary stricture and its anatomical relationship with adjacent blood vessels were clearly displayed.The coincidence rate of planned and actual operations was 95.5％ (63/66).The mean operation time,intraoperative blood loss,rate of stone clearance,complication rate and duration of hospital stay of 63 patients were (117 ± 9) minutes,(18 ± 1) ml,92.4％ (61/66),6.1％ (4/66) and (15 ± 4) days,respectively.All the patients were followed up till September 2012,the median survival time was 16 months (range,1-69 months),and the recurrence rate of hepatolithiasis was 9.1％ (6/66).One patient died of tumor metastasis and multi-organ dysfunction syndrome postoperatively.Conclusion MI-3DVS could effectively improve the safety and efficiency of PTCSL for patients with hepatolithiasis.
