Objective: To evaluate the efficacy of neoadjuvant chemotherapy (NACT) in the treatment of locally advanced olfactory neuroblastoma (ONB), and to explore the factors related to the efficacy of NACT. Methods: A total of 25 patients with ONB who underwent NACT in Beijing TongRen Hospital from April 2017 to July 2022 were retrospectively analyzed. There were 16 males and 9 females, with an average age of 44.9 years (ranged 26-72 years). There were 22 cases of Kadish stage C and 3 cases of stage D. After multiple disciplinary team(MDT) discussion, all patients were treated sequentially with NACT-surgery-radiotherapy. Among them, 17 cases were treated with taxol, cis-platinum and etoposide (TEP), 4 cases with taxol, nedaplatin and ifosfamide (TPI), 3 cases with TP, while 1 case with EP. SPSS 25.0 software was used for statistical analysis, and survival analyses were calculated based on the Kaplan-Meier method. Results: The overall response rate of NACT was 32% (8/25). Subsequently, 21 patients underwent extended endoscopic surgery and 4 patients underwent combined cranial-nasal approach. Three patients with stage D disease underwent cervical lymph node dissection. All patients received postoperative radiotherapy. The mean follow-up time was 44.2 months (ranged 6-67 months). The 5-year overall survival rate was 100.0%, and the 5-year disease-free survival rates was 94.4%. Before NACT, Ki-67 index was 60% (50%, 90%), while Ki-67 index was 20% (3%, 30%) after chemotherapy [M (Q₁, Q₃)]. The change of Ki-67 before and after NACT was statistically significant (Z=-24.24, P<0.05). The effects of age, gender, history of surgery, Hyams grade, Ki-67 index and chemotherapy regimen to NACT were analyzed. Ki-67 index≥25% and high Hyams grade were related to the efficacy of NACT (all P<0.05). Conclusions: NACT could reduce Ki-67 index in ONBs. High Ki-67 index and Hyams grade are clinical indicators sensitive to the efficacy of NACT. NACT-surgery-radiotherapy is effective for patients with locally advanced ONB.

OBJECTIVE: To explore the transcriptional gene expression profile up-regulated in human macrophages stimulated by interferon-γ (IFN-γ) and the underlying intracellular signaling mechanisms. METHODS: RNA-seq was used to sequence and compare the differential gene expression profiles of human macrophage cell line U937 before and after IFN-γ stimulation, and the significantly up-regulated genes were screened out, which were verified by fluorescence-based real-time quantitative polymerase chain reaction (qPCR) in U937 and THP1 cell lines, respectively. JAK/STAT, MAPK/ERK and PI3K/AKT pathway inhibitors were added to simultaneously to the cultured U937 cells upon IFN-γ priming to detect their effects on the expressions of the up-regulated genes to explore the key regulatory mechanisms. RESULTS: RNA-seq and qPCR results showed that, the well-recognized chemokines CXCL9, CXCL10 and CXCL11, the APOL family including APOL1, APOL2, APOL3, APOL4, APOL6 and GBP family GBP1, GBP2, GBP3, GBP4 and GBP5 as well were significantly up-regulated in IFN-γ-stimulated U937 cells. JAK/STAT3 pathway inhibitor inhibited the upregulation of APOL1, APOL4, GBP1, GBP4 and GBP5 genes induced by IFN-γ, while MAPK/ERK pathway inhibitor inhibited the upregulation of CXCL10 gene. PI3K/AKT pathway inhibitor inhibited the upregulation of APOL1,APOL4, APOL6, GBP1 and GBP5 genes induced by IFN-γ, all three signal pathway inhibitors could inhibit the upregulation of CXCL9 gene, and none of them could inhibit the upregulation of APOL3 gene. CONCLUSION Upon IFN-γ stimulation, some family molecules of APOL and GBP in macrophages are significantly up-regulated, and PI3K/AKT, JAK/STAT3 and MAPK/ERK pathways have positive regulation on their expressions, respectively.

Background: Malignant pleural effusion (MPE) is a complicated condition of patients with advanced tumors. Further dissecting the microenvironment of infiltrated immune cells and malignant cells are warranted to understand the immune-evasion mechanisms of tumor development and progression. Methods: The possible involvement of microRNAs (miRNAs) in malignant pleural fluid was investigated using small RNA sequencing. Regulatory T cell (Treg) markers (CD4, CD25, forkhead box P3), and Helios (also known as IKAROS Family Zinc Finger 2 [IKZF2]) were detected using flow cytometry. The expression levels of IKZF2 and miR-4772-3p were measured using quantitative real-time reverse transcription polymerase chain reaction. The interaction between miR-4772-3p and Helios was determined using dual-luciferase reporter assays. The effects of miR-4772-3p on Helios expression were evaluated using an in vitro system. Correlation assays between miR-4772-3p and functional molecules of Tregs were performed. Results: Compared with non-malignant controls, patients with non-small cell lung cancer had an increased Tregs frequency with Helios expression in the MPE and peripheral blood mononuclear cells. The verified downregulation of miR-4772-3p was inversely related to the Helios⁺ Tregs frequency and Helios expression in the MPE. Overexpression of miR-4772-3p could inhibit Helios expression in in vitro experiments. However, ectopic expression of Helios in induced Tregs reversed the effects induced by miR-4772-3p overexpression. Additionally, miR-4772-3p could regulate Helios expression by directly targeting IKZF2 mRNA. Conclusion Downregulation of miR-4772-3p, by targeting Helios, contributes to enhanced Tregs activities in the MPE microenvironment.

Objective: To evaluate clinical outcomes of autologous and allogeneic peripheral blood stem cell transplantation (PBSCT) for aggressive peripheral T-cell lymphoma (PTCL). Methods: From June 2007 to June 2017, clinical data of PTCL patients who underwent PBSCT were assessed retrospectively. Results: Among 41 patients, 30 was male, 11 female, and median age was 38(13-57) years old. Seventeen patients with autologous PBSCT (auto-PBSCT) and 24 patients with allogeneic PBSCT (allo-PBSCT) were enrolled in this study. Eight patients (8/17, 47.1%) in auto-PBSCT group were ALK positive anaplastic large cell lymphoma (ALCL), 7 patients (7/24, 29.2%) with NK/T cell lymphoma and 9 patients (9/24, 37.5%) with PTCL-unspecified (PTCL-U) in allo-PBSCT group (P=0.035). There were 58.8% patients (10/17) in complete response (CR) status and 11.8% (2/17) in progression disease (PD) status before transplantation in auto-PBSCT group, and 8.3% (2/24) in CR status and 45.8% (11/24) in PD status before transplantation in allo-PBSCT group (P=0.026). The 2-years cumulative overall survival (OS) were (64.0±10.8)% and (53.5±9.7)% for auto-PBSCT and allo-PBSCT respectively (P=0.543). The 2-years cumulative disease-free survival (DFS) were (57.1±12.4)% and (53.5±10.6)% for auto-PBSCT and allo-PBSCT respectively (P=0.701). In patients with dead outcomes after PBSCT, 83.3% (5/6) of death cause was relapse in auto-PBSCT and 41.7% (5/12) of death cause was relapse in allo-PBSCT. Conclusion: Both auto-PBSCT and allo-PBSCT were effective for PTCL. Allo-PBSCT maybe was better than auto-PBSCT for high-risk PTCL with poor prognosis.

OBJECTIVETo explore the factors which may have influences on hematopoietic reconstitution of the auto-peripheral blood stem cell transplantation(auto-PBHSCT).

METHODSThe successful rate, the time of hematopoietic reconstitution and implantation status at 28 days after transplantation of 177 patients received auto-PBSCT were retropectively analyzed, in order to explore the factors which may have influences on hematopoietic reconstitution.

RESULTSThe median time of neutrophil recovery was 12 days (8-21 days), implantation rate was 98.9%, all patients' neutrophil were recovered in 28 days. The median time of platelet recovery was 17 days (7-420 days), implantation rate was 95.5%, the cumulative incidence of platelet recovery at day 28 was 80.8%. Univariate analysis showed that the CD34cell number and the use of TPO had effect on neutrophils recovery time; the disease kinds, conditioning regimen and the infused CD34cell number had influence on platelets recovery time. Multivariate analysis showed that the CD34cell number was the independent influencing factor of neutrophils reconstitution time; the disease kinds, the CD34cell number were the independent influencing factors of platelet reconstitution time. Disease kinds and the CD34cell number were the independent influencing factors of hematopoietic reconstitution status of 28 days after transplantation.

CONCLUSIONIn auto-PBHSCT patients, disease kinds, conditioning regimen, the infused CD34cell number and the use of TPO have been confirmed to be independent influencing factors on hematopoietic reconstitution.

OBJECTIVETo investigate the therapeutic efficacy of allogeneic peripheral blood hematopoietic stem cell transpdantation (allo-HSCT) for T lymphoblastic lymphoma (T-LBL).

METHODSThe clinical data of 14 adult patients with T-LBL treated with allo-HSCT were collected, the hematopoietic reconstruction, survival and relapse, as well as overall survival (OS) rate, event-free survival (EFS) rate of 1, 3 and 5 years were analysed retrospectively.

RESULTSAll the patients were engrafted with neutrophil successfully, the median time of absolute neutrophil count >0.5 × 10(9)/L was 13 (10-19) d; 13 patients were engrafted with platelets successfully, the median time of Plt count >20 × 10(9)/L was 17 (12-62) days. The acute GVHD occurred in 6 patients, but among them only 1 case with 3 grade of aGVHD; out of 14 patients, 5 developed chronic GVHD. The transplant-related mortality at 100 days was 7.1% (1/14), mainly from coronary heart disease and pulmonary infection. The median follow-up time was 26.5 months, the estimated 1, 3 and 5 year OS rate was 85.7%, 47.6% and 38.1%, respectively, and estimated 1, 3 year EFS rate was 85.7%, 34.4% and 34.1%, respectively. The relapse rate was 42.8% (6/14) and the median relapse time was 22.5% months after transplantation. Up to now, 7 patients still survive, 1 patient out of them have survived for 103 months.

CONCLUSIONThe allo-HSCT is a safe and effective method for treatment of T-LBL.

OBJECTIVE: To explore the immune cytotoxic effect and the maximum non-effect dose of trichloroethylene( TCE) on Jurkat T cells in vitro. METHODS: i) Naive and activated Jurkat T cells were treated with different concentrations of TCE( 0. 10, 0. 50, 1. 00, 2. 00, 5. 00, 10. 00 mmol / L). Phorbol-12-myristate-13-acetate and ionomycin were used as agonist. No TCE was used in the control group and dimethyl sulfoxide( DMSO) was used as the solvent group. The morphology of Jurkat T cells was observed using a light microscope and the survival rate of Jurkat T cells was investigated using CCK-8 essay after cells were cultured for 24,48 and 72 hours. ii) Nave and activated Jurkat T cells were treated with different concentrations of TCE( 0. 00,0. 02,0. 20,2. 00 mmol / L). The apoptosis of cells was detected using flow cytometry and the level of interleukin-2( IL-2) in supernatant was detected using enzyme linked immunosorbent assay after cells were cultured for 24,48 and 72 hours. RESULTS: i) Cytotoxic effect was observed after cells were exposed to 10. 00 mmol / L TCE for 24 hours. Cells dispersed,cell volume diminished,cell membrane ruptured,cytoplasm condensed and increased outflow of intercellular organelles. The effect of interaction between exposure dose and exposure time was statistically significant on cell survival rate( P < 0. 01). Compared with the control and DMSO groups at the same time points,there were no significant differences in the 0. 10,0. 50,1. 00 and 2. 00 mmol / L TCE treatment groups in cell survival rates in three different time points( P > 0. 05),while the cell survival rates of 5. 00 and 10. 00 mmol / L TCE treatment groups were significantly decreased( P < 0. 01). ii) When TCE concentration was 0. 00-2. 00 mmol / L,there were no significant differences in the main effect of exposure dose and interactions of between exposure dose and cell type or exposure time on cell apoptosis rate( P > 0. 05). Compared with the same time points and groups of naive Jurkat T cells,the levels of IL-2 of activated Jurkat T cells were significantly increased( P < 0. 01). In the three different time points,the level of IL-2 of activated Jurkat T cells increased in accordance with the TCE exposure dose,showing a dose-effect relationship( P < 0. 01). The level of IL-2 of activated Jurkat T cells increased in accordance with TCE exposure time,showing a time-effect relationship( P < 0. 01). CONCLUSION:s TCE at the level of 2. 00 mmol / L had no observed effect in Jurkat T cells. High doses of TCE( ≥5. 00 mmol / L) showed cytotoxic damages to naive and activated Jurkat T cells and low doses of TCE( ≤2. 00 mmol / L) could stimulate activated Jurkat T cells secrete IL-2 in a dosedependent and time-dependent manner.
