ABSTRACT
<p><b>OBJECTIVE</b>To discuss the feasibility of the operation of minimal invasive with gallbladder preserved via choledochoscopy.</p><p><b>METHODS</b>From February 1992 to June 2006, there were 760 patients who underwent cholecystolithiasis treated with the minimal invasive operation with gallbladder preserved via choledochoscopy, among which there were 428 males and 332 females, aged from 18 to 81 years old. All cases were diagnosed by ultrasonography and their gallbladder functions were proved normal by the examination of oral cholecystography or ECT before operation. In the operation gallstones were removed from gallbladder completely.</p><p><b>RESULTS</b>There were 612 cases who were followed up for 1-15 years and the follow-up rate was 80.5%. All patients recovered well after operation. The post-operation rate of recurrence of gallstone was 0.49%, 4.39%, 5.83%, 6.60%, 7.21% and 8.38% within the first year, the second year, the third year, the fifth year, the seventh year and the ninth year respectively, rate of recurrence of gallstone were 10.11% within both the tenth and the fifteenth year.</p><p><b>CONCLUSIONS</b>The minimal invasive operation with gallbladder preserved via choledochoscopy is effective to cholecystolithiasis patients whose gallbladder function is normal. It is a feasible operation that preserves the normal functional gallbladder and improves the patients' life quality.</p>

S801 leukemic cell line established by our department was used as cells for interferon (IFN) induction and stimulating induction. S801 cell culture of concentration of 5-8x10~6 cells/ml was used for IFN induction and IFN titer of 3.55 Lg IU/ml was obtained by classical procedure. The IFN titer obtained S801 cell cultures after pretreatment with Ciwujia eleutherosides B. D and E or polysaccharide (PES) combined with priming procedure,then using Sendai Virus as an inducer was 10-20 times higher than that in cultures without any pretreatment. These Chinese medical herbs may be the ideal IFN helpinducers. This cell line may be applied for IFN production.
