Objective To study the expression characteristics of serum antinuclear antibodies (ANA) in lymphoma patients as well as their target antigens in cells, and to explore the possible relationship between lymphoma and ANA. Methods Indirect immunofluorescence was used to detect the ANA expression level in 100 cases of lymphoma and 200 population-based controls. Then the relationship between lymphoma and ANA was investigated by means of 1:2 matched with logistic regression models. Results The positive rate of ANA in lymphoma patients was higher than that in the control group [28 % (28/100) vs. 7 % (14/200)], with a statistical difference (OR= 13.66, 95 %CI 4.10-45.57, P< 0.01). The positive rate of ANA in females was higher than that in males, and the positive rate of ANA became higher with age. Lymphoma group had more complex fluorescence pattern and wider target antigen spectrum compared with the control group. Conclusions Detection of ANA in lymphoma may help in the early diagnosis,prognosis and treatment. ANA target antigen spectra of lymphoma patients are different from those in healthy people as well as patients with autoimmune disease. Further efforts should be made to identify the target antigens as well as their biological roles and clinical significances.

Objective To study the anti-tumor effects of humulon on arylamine N-acetyltransferase-1(NAT1)activity.Methods Employing HPLC,using PABA as substrate,in intact SGC-7901 cells and their cytoplasm,making PABA being acetylated to Ac-PABA by NAT1 as the activity of NAT1.Reverse transcriptase polymerase chain reaction(RT-PCR)assay was used to study the expression of the NAT1 mRNA.Results The results show that humulon could inhibit the production of Ac-PABA in intact SGC-7901 cell and the cytoplasm,the production of Ac-PABA was gradually increased with the interaction time increasing.But comparing with corresponding negative control group's,the production of Ac-PABA was decreased evidently and the humulone could inhibit the expression of NAT1 mRNA.Conclusion Humulon could prevent the occurrence and deterioration of cancer.Its mechanisms can be attributed to its effect on decreasing the production of acetylation of carcinogenic aromatic amines,which is acetylated from aromatic amines,and inhibiting the NAT1 activity and expression of NAT1 mRNA.
