RESUMO
The peripheral T-cell lymphoma (PTCL) is a heterogeneous group of aggressive non-Hodgkin lymphoma. The overall prognosis is poor with high risk of relapse after the first-line treatment. The 61st American Society of Hematology (ASH) Annual Meeting has covered many treatment advances of PTCL, especially for relapsed/refractory patients. The main contents include histone deacetylase inhibitors (HDACi), farnesyl transferase (FT) inhibitors, dual inhibitors of SYK/JAK signaling pathway, PI3K inhibition agent, programmed death 1 (PD-1) monoclonal antibody, anti-CD38 monoclonal antibody, and EZH1/2 dual inhibitor. New protocols and drugs have brought hope for relapsed/refractory PTCL patients.
RESUMO
Objective To explore the bioactive constituents of Gentiana rhodantha for its serum pharmacochemistry research.Methods The blood migrating constituents of Gentiana rhodantha were determined by comparing the HPLC fingerprints of the aqueous extracts,drug contained serum and blank serum.Results Twenty compounds were detected in drug contained serum,four among which were original constituents of Gentiana rhodantha,the rest might be metabolites of the original ingredients.Conclusion These twenty constituents absorbed in blood could be the bioactive components of Gentiana rhodantha.Further studies will be useful to clarify the bioactive constituents and action mechanisms of Gentiana rhodantha.
RESUMO
Objective To quantify sjTREC using a modified method in patients who underwent allogeneic hematopoietic stem transplantation (all-HSCT),and determine the level of thymic output function and analyse the influencing factors in post-allo-HSCT patients.Methods Real time quantitative PCR was used to detect sjTREC levels from the peripheral blood DNA of pre-transplantation,14 d,28 d,3 m,6 m,9 m,1 y,1.5 y,2 y,2.5 y,and above 2.5 y after HSCT,and analyse thymic output function and related factors after HSCT.sjTREC levels in 24 normal individuals were also determined to use as the normal range.Results The mean of Log (sjTREC copies/ml) in normal individuals was 3.74±0.26.Negative correlation existed between thte Log sjTREC and the age (r =-0.65,P ＜ 0.01).There was no clear association between the TREC and the gender.Log sjTREC in pre-transplantation patients was 3.09±0.52,and the levels of sjTREC in 14 d,28 d,6 m,1 y after HSCT were 1.18±0.22,2.16±0.31,1.31±0.2,1.83±0.31,respectively.There was no significant difference between normal individuals and patients 1.5 years after HSCT.The post-transplantation level of sjTREC was not related to the age,but was negatively correlated to the acute graft versus host disease (aGVHD) 1 year after HSCT.There was no difference between patients with or without aGVHD 1.5 years post-HSCT.Conclusion The modified method for detecting sjTREC is applicable to allo-HSCT.The recovery of thymic output function after allo-HSCT is slow,in which aGVHD may have a negative effect.
