Clinical Observation of Venetoclax Combined with Demethylating Agents on the Treatment of Relapsed/Refractory Acute Myeloid Leukemia / 中国实验血液学杂志

OBJECTIVE@#To investigate the efficacy and safety of venetoclax (VEN) combined with demethylating agents (HMA) in the treatment of relapsed/refractory acute myeloid leukemia (R/R AML).@*METHODS@#The clinical data of 26 adult R/R AML patients who received the combination of VEN with azacitidine (AZA) or decitabine (DAC) in Huai'an Second People's Hospital from February 2019 to November 2021 were retrospectively analyzed. The treatment response, adverse events as well as survival were observed, and the factors of influencing the efficacy and survival were explored.@*RESULTS@#The overall response rate (ORR) of 26 patients was 57.7% (15 cases), including 13 cases of complete response (CR) and CR with incomplete count recovery (CRi) and 2 cases of partial response (PR). Among the 13 patients who got CR/CRi, 7 cases achieved CRm (minimal residual disease negative CR) and 6 cases did not, with statistically significant differences in overall survival (OS) and event-free survival (EFS) between the two groups (P=0.044, 0.036). The median OS of all the patients was 6.6 (0.5-15.6) months, and median EFS was 3.4 (0.5-9.9) months. There were 13 patients in the relapse group and refractory group, respectively, with response rate of 84.6% and 30.8% (P=0.015). The survival analysis showed that the relapse group had a better OS than the refractory group (P=0.026), but there was no significant difference in EFS (P=0.069). Sixteen patients who treated for 1-2 cycles and 10 patients who treated for more than 3 cycles achieved response rates of 37.5% and 90.0%, respectively (P=0.014), and patients treated for more cycles had superior OS and EFS (both P<0.01). Adverse effects were mainly bone marrow suppression, complicated by various degrees of infection, bleeding, and gastrointestinal discomfort was common, but these could be all tolerated by patients.@*CONCLUSION@#VEN combined with HMA is an effective salvage therapy for patients with R/R AML and is well tolerated by patients. Achieving minimal residual disease negativity is able to improve long-term survival of patients.

Clinical study of 19 cases of steroid-refractory gastrointestinal acute graft-versus-host disease after allogeneic hematopoietic stem cell transplantation with fecal microbiota transplantation / 中华血液学杂志

Objective: To investigate the clinical efficacy of fecal microbiota transplantation (FMT) for treating steroid-refractory gastrointestinal acute graft-versus-host disease (GI-aGVHD) . Methods: This analysis included 29 patients with hematology who developed steroid-refractory GI-aGVHD after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in Huaian Hospital Affiliated to Xuzhou Medical University from March 2017 to March 2022. Among them, 19 patients underwent FMT treatment (the FMT group) and 10 patients did not (the control group). The efficacy and safety of FMT were assessed, as well as the changes in intestinal microbiota abundance, lymphocyte subpopulation ratio, peripheral blood inflammatory cytokines, and GVHD biomarkers before and after FMT treatment. Results: ① Complete remission of clinical symptoms after FMT was achieved by 13 (68.4%) patients and 2 (20.0%) controls, with a statistically significant difference (P<0.05). Intestinal microbiota diversity increased and gradually recovered to normal levels after FMT and FMT-related infections did not occur. ②The proportion of CD3(+) and CD8(+) cells in the FMT group after treatment decreased compared with the control group, and the ratio of CD4(+), regulatory T cells (Treg), and CD4(+)/CD8(+) cells increased (all P< 0.05). The interleukin (IL) -6 concentration in the FMT group was lower than that in the control group [4.15 (1.91-5.71) ng/L vs 6.82 (2.40-8.91) ng/L, P=0.040], and the IL-10 concentration in the FMT group was higher than that in the control group [12.11 (5.69-20.36) ng/L vs 7.51 (4.10-9.58) ng/L, P=0.024]. Islet-derived protein 3α (REG3α) was significantly increased in patients with GI-aGVHD, and the REG3α level in the FMT group was lower than that in the control group after treatment [30.70 (10.50-105.00) μg/L vs 74.35 (33.50-139.50) μg/L, P=0.021]. Conclusion: FMT is a safe and effective method for the treatment of steroid-refractory GI-aGVHD by restoring intestinal microbiota diversity, regulating inflammatory cytokines, and upregulating Treg cells.

Correlation of blood flow assessed by CT perfusion imaging and microvascular ultrastructure in non-small cell lung cancer: a preliminary study / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the correlation between blood flow assessed by CT perfusion imaging and characteristics of microvascular ultrastructure in non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>twenty-eight patients with non-small cell lung cancer proven surgically and pathologically underwent perfusion CT examination. The patients were divided into a hyper-perfusion group and a hypo-perfusion group by the median value of blood flow, and then the differences of microvascular ultrastructure in the two groups were analyzed.</p><p><b>RESULTS</b>The median BF value of the 28 patients was 36.40 ml×100 g(-1)×min(-1). Take this median value as the boundary, the group with hypo-perfusion showed a significantly lower BF value than the group with hyper-perfusion [(30.84 ± 4.79) ml×100 g(-1)×min(-1) vs. (49.67 ± 10.89) ml×100 g(-1)×min(-1), t = -5.925, P < 0.001]. The group with lymph node metastasis showed a significantly lower BF value than the group without lymph node metastasis [(30.78 ± 5.24) ml×100 g(-1)×min(-1) vs. (50.73 ± 11.16) ml×100 g(-1)×min(-1), t = 3.490, P = 0.015]. The maturity of microvessels of the hyper-perfusion group was higher than that of the hypo-perfusion group. Under the electron microscope, the microvessels in the hypo-perfusion group showed a more narrow lumen, poorer integrity of basement membrane, a more close relationship between cancer cells and microvascular wall, and cancer cells were more easily seen in the microvascular lumen.</p><p><b>CONCLUSION</b>The blood flow value of CT perfusion imaging may be related with the abnormal microvascular ultrastructure, and may be helpful to the prediction of metastasis risk in NSCLC.</p>

Effects of specific siRNA targeting at bcr-abl fusion gene and its combination with p27 gene clone on chronic myeloid leukemia cell line K562 / 中国实验血液学杂志

This study was purposed to explore the effect of specific small interfering RNA targeting at bcr-abl fusion gene and its combination with p27 gene clone on the proliferation, cell cycle and apoptosis of chronic myeloid leukemia (CML) cell line K562. CML cell line K562 was used as the study object. A 21nt siRNA targeting at the fusion site of b3:a2 mRNA in bcr-abl fusion gene was designed, synthesized and transfected into the K562 cells as RNA interference group. Northern blot was used to detect the bcr-abl fusion gene, Western blot was used to detect the expression of P210 protein and apoptosis-related protein BCL-xL after the transfection. Meanwhile, p27 gene was amplified from peripheral blood mononuclear cells by RT-PCR, and was confirmed to be correct by sequencing, then p27-pcDNA3.1 vector was constructed and transfected into K562 cell line by Lipofectin. After being selected with G418, p27-pcDNA3.1-K562 cell clone stably expressing p27 was isolated. P27 protein was identified by Western blot. Finally, siRNA and p27 gene clone were together applied to K562 cells, the cell survival rate was tested by MTT. The cell cycle and the apoptosis were tested by flow cytometry. The result showed that in contrast with the control group, the expression level of bcr-abl fusion gene was much lower in siRNA group, about 18.4% of K562 cells in siRNA group were apoptotic at 24 hours after siRNA transfection, and the expression of apoptosis-associated protein BCL-xL was greatly down-regulated. The expression of P27 protein could be detected by Western blot in p27-pcDNA3.1-K562 cells. The strong inhibition of cell proliferation was observed in p27-pcDNA3.1-K562 cells, as compared with control K562 cells. The count of p27-pcDNA3.1-K562 cells in G(0)/G(1) phase increased apparently, but that in S phase declined greatly. Cell cycle was arrested in G(0)/G(1) phase. After the combination of p27-pcDNA3.1-K562 cells with specific siRNA, the percentage of apoptosis obviously increased and cell survival rate significantly declined. It is concluded that the specific siRNA distinctly inhibits the expression of bcr-abl fusion gene, and can induce K562 cell apoptosis. The combination of specific siRNA with P27 gene clone displays a synergy of inhibition and pro-apoptosis effects to K562 cells.

OBJECTIVE@#To establish the hyperlipoidemia model and observe its effect on the expression of plasma vWF, PAl-1 and t-PA after endothelial cell injury caused by the model at different time in rats.@*METHODS@#Sixty male Sprague-Dawley rats weighing (200+/-20)g were randomly divided into 6 groups (n=10 in each): high flat composition for 7 weeks (Group A7), 8 weeks (Group A8)and 9 weeks(Group A9), common bait vessel feeding for 7 weeks(Group C7), 8 weeks(Group C8) and 9 weeks (Group C9). When it reached the setting time, the rats were put to death and the serum was separated to detect the blood-fat immediately. Meanwhile, the pathological sections of the rat aorta were made to observe the endothelial injury. The blood plasma was separated and the content of the blood plasma PAl-1, t-PA and vWF was detected by ELISA assay.@*RESULTS@#(1)TG, TC and LDL of the rats intragastrically administrated high flat composition were higher than those of the control group,and HDL increased with time at first, but lowered when longer than 9 weeks. (2) There were no lesions in the aortic endothelium in all rats of Group C through optical microscope,while different lesions in the aortic endothelium in all rats of Group A were observed. (3)In the 3 groups A, the plasma vWF and PAI-1 were gradually increasing with time while t-PA gradually decreased. (4) There was no significant difference of vWF between Group A7 and Group A8. PAI-I increased gradually with the aggravation of endotheliocytes in Group A; and t-PA decreased gradually with the aggravation of endothelium in Group A.@*CONCLUSION@#(1) As intragastric administration prolongs, the plasma lipid of rats keeps increasing with the aggravation of the endodermis injury. (2) PAI-1, t-PA and vWF are the molecular markers of vascular endothelial cell injury in rats. (3) PAI-l and t-PA are more sensitive than vWF in reflecting the endothelial cell injury in hyperlipemia early metaphase.
