OBJECTIVE: To evaluate the diagnostic value of the expression levels of cytokines interleukin-6(IL-6), interleukin-10 (IL-10) and chemokine （C-X-C motif） ligand-13 (CXCL-13) in cerebrospinal fluid (CSF) for central nervous system infiltration of lymphoma. METHODS: Forty patients diagnosed as lymphoma or acute lymphoblastic leukemia in General Hospital of Northern Theater Command from July 2020 to July 2021 were collected and recorded their CSF indexes, including pressure, protein, Pandy test, nucleated cell count, glucose and chlorine content in CSF. The levels of cytokines IL-6, IL-10 and CXCL-13 were detected by Enzyme-linked immunosorbent assay. RESULTS: The patients were divided into CNSI (central nervous system infiltration) group and non-CNSI group, the average levels of IL-6, IL-10, CXCL-13 and IL-10/IL-6 ratio in CNSI group were higher than those in non-CNS group, but the difference of IL-10/IL-6 ratio between the two groups was statistically significant (P<0.05). Then the patients were divided into protein elevated(n=14) group and protein normal group(n=26), the levels of IL-6 ［ (5.78±2.69) pg/ ml］ and CXCL-13 ［(0.83±0.59) pg/ml］ in protein elevated group were significantly higher than those in the protein normal group ［IL-6: (2.41±1.16) pg/ml; CXCL-13: (0.38±0.18) pg/ml］ (P<0.05). Further analysis of the expression levels of the cytokines in non-CNSI group (n=32), IL-6, IL-10, CXCL-13 level and IL-10/IL-6 ratio in the protein elevated group (n=12) were higher than those in the protein normal group (n=20), but the difference was not statistically significant. CONCLUSION The levels of IL-6, IL-10 and CXCL-13 in CSF of lymphoma patients with CNS infiltration were higher than those in non-CNS infiltration group, and those in patients with protein elevated group are higher than those in the protein normal group.

UNLABELLED: AbstractObjective: To analyze the expression of FOSB in acute myeloid leukemia （AML） and its correlation with prognosis of the patient based on the large sample data. METHODS: The genome, transcriptome, gene chip and clinical information from multiple public databases were statistical analyzed. RESULTS: The expression of FOSB gene in AML patients was significantly higher than that in normal people. The prognostic analysis of the 163 patients showed that the patients with high FOSB expression showed longer OS and EFS than those with FOSB low expression. The patients were further divided into chemotherapy group and allogeneic hematopoietic stem cell transplantation (allo-HSCT) group according to the treatment method, and then each group was divided into two subgroups (FOSBhigh, FOSBlow) according to the median expression level of FOSB. In the allo-HSCT group, the patients with FOSB high expression was longer event-free survival (EFS: P=0.017) and overall survival (OS: P=0029). At the same time, allo-HSCT in patients with high FOSB expression could improve the prognosis of the patients (Chemotherapy vs Allo-HSCT, OS: P<0.001, EFS: P=0.007). Multivariate analysis showed that the high expression of FOSB was an independent favorable prognostic factor for EFS and OS (EFS: HR=0.501， P=0.019; OS: HR=0.461， P=0.009) of the patients. CONCLUSION The high expression of FOSB indicated a good prognosis for acute myeloid leukemia.

OBJECTIVE: To compare the operation complexity and accuracy of traditional splint impression technique and impression technique with prefabricated rigid connecting bar system for full-arch implants-supported fixed protheses in vitro. METHODS: Standard mandibular edentulous model with six implant analogs was prepared. The implants were placed at the bone level and multiunit abutments screwed into the implants. Two impression techniques were performed: the traditional splint impression technique was used in the control group, and the rigid connecting bar system was used in the test group. In the control group, impression copings were screwed into the multiunit abutments and connected with autopolymerizing acrylic resin. Open tray impression was fabricated with custom tray and polyether. In the test group, cylinders were screwed into the multiunit abutments. Prefabricated rigid bars with suitable length were selected and connected to the cylinders with small amount of autopolymerizing acrylic resin, and open tray impression was obtained. Impression procedures were repeated 6 times in each group. The working time of the two impression methods were recorded and compared. Analogs were screws into the impressions and gypsum casts were poured. The gypsum casts and the standard model were transferred to stereolithography (STL) files with model scanner. Comparative analysis of the STL files of the gypsum casts and the standard model was carried out and the root mean square (RMS) error value of the gypsum casts of the control and test groups compared with the standard model was recorded. The trueness of the two impression techniques was compared. RESULTS: The work time in the test group was significantly lower than that in the control group and the difference was statistically significant [(984.5±63.3) s vs. (1 478.3±156.2) s, P < 0.05]. Compared with the standard model, the RMS error value of the implant abutments in the test group was (16.9±5.5) μm. The RMS value in the control group was (20.2±8.0) μm. The difference between the two groups was not significant (P>0.05). CONCLUSION The prefabricated rigid connecting bar can save the chair-side work time in implants immediate loading of edentulous jaw and simplify the impression process. The impression accuracy is not significantly different from the traditional impression technology. The impression technique with prefabricated rigid connecting bar system is worthy of clinical application.

Objective: To explore the gene-lifestyle interaction on coronary heart disease (CHD) in adult twins of China. Methods: Participants were selected from twin pairs registered in the Chinese National Twin Registry (CNTR). Univariate interaction model was used to estimate the interaction, via exploring the moderation effect of lifestyle on the genetic variance of CHD. Results: A total of 20 477 same-sex twin pairs aged ≥25 years were recruited, including 395 CHD cases, and 66 twin pairs both had CHD. After adjustment for age and sex, no moderation effects of lifestyles, including current smoking, current drinking, physical activity, intake of vegetable and fruit, on the genetic variance of CHD were found (P>0.05), suggesting no significant interactions. Conclusion: There was no evidence suggesting statistically significant gene-lifestyle interaction on CHD in adult twins of China.

OBJECTIVE: To investigate the effects of dasatinib on the maturation of monocyte-derived dendritic cells (moDCs) derived from healthy donors (HDs) and chronic myelogenous leukemia (CML) patients. METHODS: Peripheral blood mononuclear cells (PBMCs) were isolated from HDs (n=10) and CML patients (n=10) who had got the remission of MR4.5 with imatinib treatment. The generation of moDCs from PBMCs was completed after 7 days of incubation in DC I culture medium, and another 3 days of incubation in DC II culture medium with or without 25 nmol/L dasatinib. On the 10th day, cells were harvested and expression of molecules of maturation related marker were assessed by flow cytometry. The CD80⁺CD86⁺ cell population in total cells was gated as DCs in the fluorescence-activated cell storting (FACS) analyzing system, then the expression of CD83, CD40 or HLA-DR in this population was analyzed respectively. RESULTS: The proportion of CD80⁺CD86⁺ cells in total cells didn't show a statistical difference between HD group and patient group (89.46%±9.70% vs 87.39%±9.34%, P=0.690). Dasatinib significantly enhanced the expression of the surface marker CD40 (P=0.008) and HLA-DR (P=0.028) on moDCs derived from HDs compared with the control group, while the expression of CD83 on moDCs didn't show a significant difference between dasatinib group and the control group (P=0.428). Meanwhile, dasatinib significantly enhanced the expression of the surface marker CD40 (P=0.023), CD83 (P=0.038) and HLA-DR (P=0.001) on moDCs derived from patients compared with the control group. CONCLUSION For CML patients, the same high proportion of moDCs as HDs can be induced in vitro, which provides a basis for the application of DC-based immunotherapy strategy. Dasatinib at the concentration of 25 nmol/L can efficiently promote the maturation of moDCs derived from HDs and CML patients in vitro. Dasatinib shows potential as a DC adjuvant to be applied in DC-based immunotherapy strategies, such as DC vaccine and DC cell-therapy.

OBJECTIVE: To observe the mutation and expression of TCF3 gene in Burkitt's lymphoma (BL), and explore its effect on the proliferation of BL cells and clinical efficacy and prognosis. METHODS: The mutation and expression of TCF3 in tumor tissues from BL patients were observed by the second-generation sequencing and real-time quantitative PCR. The proliferation and apoptosis of lymphoma cells after TCF3 knocked down were observed by siRNA interference technique and CCK-8 method. Survival analysis was used to observe the relationship between TCF3 mutation and the treatment efficacy and prognosis of BL patients. RESULTS: There were high frequency mutation rate (mutation rate was 23.7%) and high expression of TCF3 in BL patients. After TCF3 knocked down, cell proliferation was inhibited and apoptosis was promoted. In TCF3-siRNA group and control group, the cell proliferation rate at 48 h was (50.2±5.9)% and (96.6±11.4)%, and apoptosis rate was 30.1% and 1.5%, respectively, which showed significantly different between the two groups (P<0.001, P=0.005). The complete remission rate of patients with TCF3 mutation was low. The complete remission rate of mutant group and wild-type group was 44.4% and 82.8%, respectively (P=0.023). The 2-year progression-free survival rate and overall survival rate of the patients with TCF3 mutation was 55.6% and 61.0%, respectively, which was lower than 83.2% and 85.2% of the patients without mutation, but the differences were not statistically significant. CONCLUSION There are mutation and abnormal expression of TCF3 in patients with BL. Patients with TCF3 mutations have low remission rate and poor prognosis.

OBJECTIVE: To investigate the clinical value of oligoclonal bands (OB) in patients with multiple myeloma (MM). METHODS: The laboratory test and clinical data of 624 newly diagnosed MM patients admitted to Blood Diseases Hospital of Chinese Academy of Medical Sciences from January 2013 to December 2019 were retrospectively analyzed, including 30 patients with OB, and the clinical characteristics, treatment effects and survival of OB and non-OB patients were analyzed and compared. RESULTS: OB occurred in 11.8% (22/187) of patients who received autologous stem cell transplantation(ASCT) and only 1.8% (8/437) of patients who did not receive ASCT (P=0.000). The median time to the appearance of oligoclonal bands was 3.2(0.6-10.5) months after transplantation. The M protein types of oligoclonal bands mainly include IgG κ, IgG λ, IgM λ and λ light chains. In the presence of oligoclonal bands, 90% of patients were evaluated as complete remission (CR) and above. There were no statistically significant differences in disease stage, tumor burden, and genetic abnormalities between OB and non-OB patients. Among the all patients, the prognosis of OB patients was significantly better than that of non-OB patients, and OB patients showed deeper disease remission (significantly higher CR rate, MRD negative rate, and longer MRD negative duration). Among patients who underwent ASCT, OB patients showed earlier immune recovery, but the depth of treatment response and survival outcomes were similar between OB and non-OB patients, it was no statistically difference. Although OB patients showed earlier immune reconstitution, this did not translate into better survival, suggesting that the better prognosis of OB patients was mainly related to deeper and durable remission rather than early immune reconstitution. Further analysis in patients who received ASCT and obtained MRD negative indicated that there was no additional survival benefit in patients with OB. CONCLUSION The better prognosis of OB patients may be related to the deeper treatment response, but not to the early immune reconstitution. The appearance of OB is only a sign of deep remission and early immune reconstitution in patients, it cannot be translated into survival benefit of MM patients.
