To explore the role of follicular helper T cell (Tfh)/ follicular regulatory T cell (Tfr) imbalance in B-cell lymphoma (BCL).
Sixteen BCL patients who were admitted to the Department of Hematology of The First People's Hospital of Yichang and 20 healthy people from December 2019 to November 2020 were enrolled and respectively divided into observation group and control group. The levels of Tfh and Tfr in peripheral blood were detected by flow cytometry. The changes of Tfh, Tfr, and Tfh/Tfr ratio were compared and the relationship between Tfh/Tfr ratio and efficacy, prognosis was analyzed.
Compared with the healthy controls, Tfh and Tfh/Tfr ratio in peripheral blood of the BCL patients increased (P<0.05, P<0.01), while levels of Tfr was decreased (P<0.01). After chemotherapy, Tfh and Tfh/Tfr ratio in peripheral blood of the BCL patients decreased significantly than before chemotherapy (P<0.01), but Tfr was no significant difference. Multivariate analysis showed that Tfh and Tfh/Tfr ratio were positively correlated with international prognostic index (IPI) score and Ann Arbor stage (r=0.626, 0.564, 0.573, 0.608, respectively), while Tfr negatively (r=-0.504, -0.542, respectively). According to the average value of Tfh/Tfr ratio at initial diagnosis, BCL patients were divided into Tfh/Tfr high ratio group and low ratio group. It was found that the complete remission (CR) rate, overall response rate (ORR), and survival time in the high ratio group were significantly lower than the low ratio group (P<0.01).
There is an imbalance of Tfh/Tfr ratio in peripheral blood of the BCL patients, and those with a high Tfh/Tfr ratio have lower CR, ORR and shorter survival time.

To investigate the effect of arsenic disulfide (AS
S
) combined with itraconazole on the proliferation, apoptosis and hedgehog pathway of diffuse large B-cell lymphoma (DLBCL) cells.
The human DLBCL cell OCI-LY3 was treated with different concentrations of AS
S
and itraconazole. Taurocholic acid chemical Cell proliferation inhibition was detected by CCK-8, cell apoptosis rate was determined by flow cytometry. The expression levels of BCL-2, BAX, SMO and GLi1 were detected by Western blot.
The DLBCL cell viability was decreased significantly at 24, 48 or 72 h as cultured with itraconazole. Along with the increasing of itraconazole concentration, the DLBCL cell viability was significantly reduced as compared with that in control group, and the results showed statistically significant(r=-0.690,r=-0.639, r=-0.833, r=-0.808, r=-0.578). The inhibitory and apoptosis rates of the cells were significantly increased as compared with those of the single drug-treated group after treated by the combination of itraconazole and AS
S
(P<0.05). The protein levels of SMO and Glil were significantly down-regulated after treated by arsenic disulfide and itraconazole alone(P<0.01). The protein expression levels of SMO and Glil was down-regulated in the combined-treatment group(P<0.01).
Itraconazole can inhibit proliferation of DLBCL cells in a concentration-and time-dependent manner. In addition, the combination of AS
S
and itraconazole show a synergistic effects, which may be related with the down-regulated protein expression of SMO and Glil of Hedgehog signaling pathway.
