Effect of Dingkundan in Adjuvant Treatment of Patients with Radiotherapy and Chemotherapy After Endometrial Carcinoma Operation / 中国实验方剂学杂志

Objective:To observe the effect of Dingkundan in adjuvant treatment of clinical symptoms， quality of life， immune function and prognosis of patients with radiotherapy and chemotherapy after endometrial carcinoma （EC） operation. Method:Patients were divided into control group （82 cases） and observation group （86 cases） according to random number table. A total of 75 patients in control group completed the study （4 patients fell off or lose visit， and 3 patients were eliminated）， while 77 patients in observation group completed the study （5 patients fell off or lose visit， and 4 patients were deleted）. After operation， patients got brachytherapy， external pelvic irradiation and chemotherapy. Patients in control group got Bazhenwan， 1 pill/time， 2 times/day， and those in observation group got Dingkundan， 7 g/time， 2 times/day. The course of treatment lasted for 4 months， and long-time follow-up data was recorded. Before treatment， and at the second and fourth month after treatment， deficiency of Qi and blood was scored. Toxic reactions after radiotherapy and chemotherapy were recorded， and incidence rate of acute and advanced radiation injury of bladder and rectum and toxicity of chemotherapeutic drugs at grade 3 or above grade 3 level were compared. And levels of T lymphocyte subsets （CD3⁺， CD4⁺， CD8⁺ and CD4⁺/CD8⁺） were detected， European collaborative quality of life Cancer Core Scale （EORTC QLQ-C30） was evaluated， and expressions of pce125 （CA125）， epididymis protein 4 （HE4）， Dickkopf-related protein-1 （DKK1）， vascular endothelial growth factor （VEGF）， matrix metalloproteinase-9 （MMP-9） and transforming growth factor-<italic>β</italic>₁ （TGF-<italic>β</italic>₁） were tested before and after treatment. The follow-up was made for every three months， and the progression （recurrence/metastasis） of patients was recorded. Result:Scores of deficiency of Qi and blood in observation group were lower than those in control group at the second and fourth week after treatment （<italic>P</italic><0.01）. Incidence rates of acute and advanced radiation injury of bladder and rectum and toxicity of chemotherapeutic drugs at grade 3 or above grade 3 level and incidence rates of bone marrow suppression， gastrointestinal toxicity， neurotoxicity were lower than those in control group （<italic>P</italic><0.05）. Five functional dimensions and overall quality of life score based on EORTC and QLQ-C30 in observation group were higher than those in control group （<italic>P</italic><0.01）， and scores of three symptom dimensions were lower than those in control group （<italic>P</italic><0.01）. Levels of CD3⁺， CD4⁺ and CD4⁺/CD8⁺ were higher than those in the control group （<italic>P</italic><0.01）， and CD8⁺ was lower than those in the control group （<italic>P</italic><0.01）. Levels of CA125， HE4， DKK1， VEGF， MMP-9 and TGF-<italic>β</italic>₁ were lower than those in the control group （<italic>P</italic><0.01）. The disease progression rate in observation group was 18.18% （14/77）， which was lower than 33.33% （25/75） in control group （<italic>χ</italic>²=4.572， <italic>P</italic><0.05）. Conclusion:In adjuvant treatment of patients with radiotherapy and chemotherapy after EC operation， Dingkundan can reduce the symptoms of Qi and blood deficiency syndrome and side effects caused by radiotherapy and chemotherapy， improve the quality of life and immune function， inhibit the expression of tumor markers and tumor growth factor， delay the progression of tumor and improve the prognosis.

Rapid determination of optimal time for peripheral blood stem cell harvest by detecting hematopoietor progenitor cell during mobilization / 中南大学学报(医学版)

OBJECTIVE@#To develop a simple method to rapidly determine the optimal time of perpheral blood stem cell harvest.@*METHODS@#We selected 5 healthy donors mobilized with granulocyte colony-stimulating factor (G-CSF) in allogenic peripheral blood stem cell transplantation (allo-PBSCT) to continuously monitor the variety of hematopoietic stem/progenitor cells (HSC/HPC) in the peripheral blood. HPC in the peripheral blood was detected by Sysmex XE-2100 fully automated hematology analyzer with an immature myeloid information channel and the CD34+ cells and colony-forming unit-granulocyte-macrophage (CFU-GM) were determined by flow cytometry and colony culture during mobilization.@*RESULTS@#HPC was positively correlated with the CD34+ cells or CFU-GM in the peripheral blood (r = 0.82 or r = 0.85, respectively). HPC, CD34+ cells, and CFU-GM in allo-PBSCT donors obviously increased on the 4th day after the mobilization, and their peaks were on the 5th day after the mobilization. But HPC varied more than CD34+ cells and CFU-GM did.@*CONCLUSION@#Sysmex XE-2100 can rapidly monitor the variety of HSC/HPC in allo-PBSCT donors mobilizated with G-CSF, and can provide a simple and economic method to determine the optimal time of peripheral blood stem cell harvest.
