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.

Objective To evaluate the sleep characteristics of the Korean children,and explore the measurement of improving the sleep qua-lity of minority nationality children.Methods The sleep time of 1 183 from 3 to 12 years age Korean children were investigated with questionnaire The sleep time of korean children in different ages and cities were compared.Results The mean time of total sleep time in Korean children was(10.06?1.29) h,which was decreasing with the age′s increasing.The difference in different ages groups was remarkable(Pa

Objective To evaluate the effects of high intensity focused ultrasound (HIFU) on hepatic cancer cells spreading in blood.Methods AFP mRNA in peripheral blood of 19 patients with hepatocellular carcinoma was detected before and after HIFU therapy by RT PCR.Results ①Before HIFU therapy, 11 of 19 cases were AFP mRNA positive (57.9%), while the control group were all negative. AFP mRNA was correlated with some clinical parameters such as serum AFP level, tumor size, portal vein embolism and extrahepatic metastasis ( P 0.05). ③After one week of HIFU therapy, the AFP mRNA positive rate of the group with tumor size less than 8 cm was much lower than that of tumor size larger than 8 cm ( P

Objective To compare the planning systems of the simplified manual intensity modulated (SMIM) irradiation and standard tangential (ST) irradiation,in order to explore the application of SMIM technique in clinic.Methods In 64 cases of breast cancers after breast conserving surgery,each underwent both SMIM and ST planning systems.SMIM planning was designed by copying additional fields for shielding the high dose areas from internal or lateral tangential field.The high dose areas were reduced by adjusting the size of the additional field and open tangential field.To optimize the SMIM planning,3 high dose areas (＞ 103% ,＞ 105% and ＞ 107%) were shielded and 3 protocols carried out.The wedges were also optimized in ST plan.The target coverage and dose homogeneity and dose of organ at risk were compared between SMIM and ST planning systems.Results When the dose was normalized to cover the volume of 95% CTV,85% of the shielded areas in optimal SMIM planning were that of ＞ 103% high dose area,and 94% of target area was covered.The study on the volume of breast CTV showed that,in the large breast group,SMIM could not only significantly reduce the high dose areas,and the maximum dose as well as the dose of organ at risk,but also enhance the dose homogeneity index.However,no such effect was not significant in the small breast group.Conclusions The simplified manual intensity modulated technique can improve target dose homogeneity in the large breast cases instead of the standard tangential technique.
