ABSTRACT
ObjectiveTo explore the effect of Tanreqing injection combined with Ceftazide on the clinical efficacy， lung function， and laboratory inflammatory index of patients suffering from phlegm heat obstructing lung syndrome in acute exacerbation of chronic obstructive pulmonary disease （AECOPD）. MethodFrom June 2021 to June 2023， 76 patients diagnosed with phlegm heat obstructing lung syndrome in AECOPD were enrolled in the respiratory and critical medical department of Jieshou Hospital of Traditional Chinese Medicine. They were randomly divided into a control group and an observation group with 38 cases each. The control group used Ceftazidime intravenous drip and other conventional oxygen inhalation and antispasmodic treatment measures of western medicine. The observation group received Tanreqing injection intravenous drip based on the treatment of the control group， with a course of 10 days. The changes of laboratory indicators such as hs-CRP， calcitonin （PCT）， and interleukin-6 （IL-6） before and after treatment were analyzed， and the improvement of forced expiratory volume in the first second （FEV1）， forced vital capacity （FVC）， one second rate （FEV1/FVC）， assessment and improvement of the British Medical Research Society’s dyspnea index （mMRC）， self-evaluation test of chronic obstructive pulmonary disease patients （CAT）， and traditional Chinese medicine syndrome score was compared. In addition， the total effective rate between the two groups after treatment was compared. ResultAfter treatment， the hs-CRP， PCT， IL-6， FEV1， FVC， FEV1/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation of both groups improved （P<0.01）. After treatment， compared with the control group， the observation group showed more significant improvements in hs-CRP， PCT， IL-6， FEV1， FVC， FEV1/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation， and the difference was statistically significant （P<0.05，P<0.01）. The total clinical effective rate of the control group was 86.84% （33/38）， while that of the observation group was 94.74% （36/38）. The therapeutic effect of the observation group was better than that of the control group （χ2=8.471， P<0.05）. ConclusionTanreqing injection combined with Ceftazidime has obvious efficacy in the treatment of phlegm heat obstructing lung syndrome in AECOPD， which is better than the treatment of Ceftazidime antibiotics alone. It can reduce the risk of acute exacerbation， alleviate clinical symptoms， and delay the decline of lung function.
ABSTRACT
Objective@#To investigate and analyze the impact on PLT recovery of recombinant human thrombopoietin (rhTPO) in severe aplastic anemia (SAA) patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT).@*Methods@#A retrospective analysis of Hematology Division of General Hospital of Jinan Military Command was conducted in the 85 SAA cases who treated with allo-HSCT from January 2010 to March 2017. According to the administration of medicines for platelets, 85 patients were divided into rhTPO group (n=29), rhIL-11 group (n=27) and blank group (n=29), respectively. The median time of PLT ≥20×109/L, PLT ≥50×109/L, and PLT ≥100×109/L, the numbers of megakaryocytes in marrow smear (25±5) days after transplantation and the quantities of platelet transfusion were analyzed retrospectively. The adverse events of rhTPO and rhIL-11 groups were observed.@*Results@#There were no significant differences in the recovery of granulocytes and PLT ≥20×109/L among the three groups (P>0.05). The time of PLT ≥50×109/L in rhTPO group was shorter than that in blank group [16.5 (11-39) d vs 22 (14-66) d, P<0.05], as well as the time of PLT ≥100×109/L [rhTPO: 23 (12-51) d; rhIL-11: 28 (12-80) d; blank group: 35 (18-86) d, P<0.05]. Platelet transfusions were also less in rhTPO group than in rhIL-11 and blank groups [20 (10-30) U, 30 (10-50) U, 35 (10-70) U, P<0.05]. The counts of megakaryocyte in rhTPO group, rhIL-11 group and blank group were 31.5 (0-200), 12 (0-142) and 11(0-187) (P<0.05), respectively. The difference between rhTPO group and rhIL-11 group was statistically significant (P<0.05), but no difference between rhIL-11 group and blank group (P>0.05). Multivariate analysis showed that rhTPO was an independent factor for platelet recovery [HR=4.01 (95%CI 1.81-9.97), P=0.010]. The rhTPO group had no obvious adverse events.@*Conclusion@#rhTPO can promote platelet recovery of SAA patients after allo-HSCT, reduce platelet transfusion with safety.
ABSTRACT
Objective To detect the change of CD47 on T-lymphocyte subsets marked by CD3 + CD4+ and CD3+ CD8+ in the acute graft versus host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and to explore its clinical significance.Methods The peripheral blood of 30 patients was collected before and every two weeks from hematopoietic reconstitution after allo-HSCT.The expression of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ was detected by flow cytometry,and the relationship between their expression and the occurrence of aGVHD was analyzed.Results The percentage of CD3+ CD4+-and CD3+ CD8+-marked T-lymphocyte subsets showed no statistically significant difference between aGVHD group and non-aGVHDgroup [(38.95 ± 6.18)％ vs.(37.38 ± 4.6)％,and (22.35 ± 3.32)％ vs.(20.34 ±4.56) ％,respectively] (P＞0.05).The expression levels of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ was obviously increased in aGVHD group when compared to before transplantation and non-aGVHD group after transplantation,and that had no changes in non-aGVHD group when compared to before conditioning regimen after transplantation.Mean fluorescence intensity of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ [(93.70 ± 14.88) and (70.09 ± 12.51)] in aGVHD group significantly increased as compared with non-aGVHD group [(71.27-± 11.32) and (53.93 ± 8.35)] (P＜0.05).There was no significant difference in the expression of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ before and after transplantation in non-aGVHD group (P＞0.05).Moreover the expression of CD47 on T-lymphocyte subsets marked by CD3 + CD4 + and CD3 + CD8 + changed correspondingly with the outcome of aGVHD in aGVHD group.Conclusion The change of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ andCD3+ CD8+ is valuable to monitor the aGVHD after allo-HSCT,which may provide a new means for the early detection of aGVHD.
ABSTRACT
Objective To summarize the experience of improved nonmyeloablative hematopoietic stem cell transplantation(NSCT) in the treatment of severe aplastie anemia. Methods Seventeen patients with Severe Aplastic Anemia received NSCT after a nonmyeloablative conditioning.The patients were conditioned with decreased dosage of immunosuppressive agents of CTX and anti-lymphoid cell globulin or anti-thymus gland cell globulins;CsA and MMF were used to prevent the graft-versus-host disease (GVHD) after transplantation. Results 75 % of severe aplastic anemia in patients with type Ⅰ and 60 % of severe aplastic anemia in patients with type Ⅱ achieved rapid hematopoietic reconstitution, with good prognosis and implantation rate with fewer complieations and light symptoms were observed. Conclusion NSCT is an effective treatment of severe aplastic anemia.
