Objective To explore the inflnence of autologous peripheral blood hematopoietic stem cell transplantation (auto-HSCT) for lymphoma process on the quality of patients blood coagulation.Methods Plasma samples were collected before the conditioning and on day 0,7,14,28,35 follow auto-HSCT from 20 patients.The following parameters were measured:prothrombin time (PT),activated partial thromboplastin time (APTT),fibrinogen (FIB) and D-dimer(D-Di).Results Compared with the values before conditioning,a significant rise in the FIB values was detected on day 7 and day 14 after auto-HSCT,no essentially change in the FIB values was detected on day 21 and day 28 and day 35 after auto-HSCT.Other coagulation parameters investigated(PT.APTT.D-Di) remained essentially unchanged.All of the patients not concurrent thrombotic disease.Conclusion Lymphoma patients with autologous peripheral blood hematopoietic stem cell transplantation appear abnormality in coagulant function.Clinical doctors should concern.

Objective To explore the mechanism of tripterygium wilfordii polyglycoside tablets for elderly patients with relapsing refractory immune thrombocytopenic purpura (ITP),and to seek the theoretical basis for Chinese medicine treatment of this disease.Methods The clinical data of 79 patients with relapsing refractory ITP were retrospectively analyzed.According to whether the combined use of tripterygium wilfordii polyglycoside,they were divided into the control group (35 cases) and the observation group (44 cases).The control group was treated with platelet and tranexamic acid,sulfasalazine,sulforaphane sodium,hemagglutinin and other symptomatic hemostasis treatment.The observation group in symptomatic hemostasis support on the basis of treatment with tripterygium wilfordii polyglycoside tablets.The CD4+/CD8+ ratio and CD4+ CD25+ Treg expression were compared between the two groups.Results The CD4+/CD8+ ratio,CD4+ CD25+ Treg and platelet count in the control group before treatmentwere (0.96 ± 0.36),(1.21 ± 0.67) ％,(13.14 ± 6.92) × 109/L,respectively,which of the observation group were (0.92 ± 0.37),(1.19 ± 0.59) ％,(11.51 ± 6.21) × 109/L,respectively,there were no statistically significant differences between the two groups (all P ＞ 0.05).The CD4+/CD8+ ratios in peripheral blood of the observation group at 2 weeks,3 weeks and 4 weeks after treatmentwere (1.04 ±0.56),(1.55 ±0.34),(1.59 ±0.41),respectively,there were statistically significant differences between the two groups (t =9.994,9.797,all P ＜ 0.05).The CD4+ CD25+ Treg proportions in the observation group at 2 weeks,3 weeks and 4 weeks after treatmentwere (1.01 ± 0.61) ％,(1.06:±:0.57) ％,(5.92 ± 0.65) ％,respectively,there was statistically significant difference between the 4 weeks after treatment and before treatment(t =5.378,P ＜ 0.05).The CD4+/CD8+ ratios in the peripheral blood of the control group were (1.01 ±0.60),(0.89 ±0.50) and (0.96 ±0.51),respectively,and the CD4+ CD25+ Treg in control group at 2 weeks,3 weeks and 4 weeks after treatment proportions were (0.99 ±0.72)％,(1.15 ±0.66)％,(1.22 ±0.56)％,respectively,there were no statistically significant differences between before and after treatment (all P ＞0.05).There were statistically significant differences in the CD4+/CD8+ ratio and CD4+ CD25+ Treg expression between the observation group and control group at 4 weeks after treatment (t =8.589,P ＜ 0.01;t =2.369,P ＜ 0.05).There was no statistically significant difference in the platelet count between the two groups(P ＞ 0.05),but the symptoms of bleeding of the observation group was lighter at 3 weeks after treatment.Conclusion Tripterygium wilfordii polyglycoside improves the expression of CD4+/CD8+ and CD4+ CD25+ Treg in peripheral blood of elderly patients with relapsed or refractory ITP.It is an ideal drug for the treatment of relapsed and refractory ITP in the elderly,it is worth further study.
