OBJECTIVE: To explore the predictors of hematologic responses of non-transfusion-dependent β-thalassemia (NTDT) to thalidomide. METHODS: 33 patients with NTDT who treated with thalidomide in the 923rd Hospital of the Joint Logistics Support Force of the People's Liberation Army from May 2016 to June 2019 were included in the study. The basic data, hematological indexes, degree of treatment response and genetic background of the patients were analyzed. RESULTS: The baseline fetal hemoglobin (HbF) level of main responders (MaR) was significantly higher than that of minor responders (MiR) and no responders (NR) (P=0.001). And the baseline HbF level was positively correlated with hemoglobin increment after treatment (r=0.601). Genetic background analysis showed that the frequencies of the genotype CT of HBG2 rs7482144 (P=0.031), the genotypes CT/CC (P=0.030) and the minor allele C (P=0.015) of HBS1L-MYB rs9399137, the genotypes AT/TT (P=0.030) and the minor allele T (P=0.028) of HBS1L-MYB rs4895440, the genotypes AG/GG (P=0.030) and the minor allele G (P=0.028) of HBS1L-MYB rs4895441 (P=0.030) in MaR group were significantly higher than those in MiR and NR groups. Comparing the area under the ROC curve (AUC) of the above indicators to predict the main response, the results demonstrated that the predictive value of baseline HbF level was significantly better than rs7482144 (0.91 vs 0.72, P=0.003), rs9399137 (0.91 vs 0.74, P=0.022), rs4895440 (0.91 vs 0.74, P=0.023) and rs4895441 (0.91 vs 0.74, P=0.023), but there was no significant difference in the predictive value between combined single nucleotide polymorphisms (SNPs) (0.91 vs 0.88, P=0.658）and baseline HbF combined SNPs (0.91 vs 0.97, P=0.132). The AUC value of baseline HbF predicting the efficacy of thalidomide as the main response was 0.91, the cut-off value was 27.4%, the sensitivity was 100%, and the specificity was 58.3% (P=0.001). CONCLUSION The hematologic response of NTDT to thalidomide is variable and complex. Compared to genetic background, baseline HbF may be a simpler and more efficient tool to predict efficacy response.

OBJECTIVE: To explore the relationship between the expression levels of JARID1B,Hes1 and MMP-9 genes and the stages of chronic myelogenous leukemia(CML) and the curative effect of imatinib mesylate (IM). METHODS: Peripheral blood samples of 15 cases of CML in chronic phase and 10 cases of CML in progressive phase were collected from the Hematology Department of Taihe Hospital affiliated to Hubei University of Medicine and 15 cases of healthy people in the Physical Examination Center. CML patients were divided into effective group and ineffective group based on the efficacy after treatment with IM, then real-time PCR was used to detect the expression levels of JARID1B, Hes1 and MMP-9 mRNA, finally, the differences in the level of gene expression and their correlations with CML stages and IM curative efficacy were analysed. RESULTS: The expression levels of Hes1 and MMP-9 in initially diagnosed patients in chronic and progressive phase without IM treatment were significantly higher than those of health people（P＜0.05）. There was no significant difference in the expression level of JARID1B between chronic phase patients and health people（P＞0.05）, but the expression level of JARID1B in the progressive phase patients was higher than that of health people （P＜0.05）. The expression levels of JARID1B and Hes1 in the IM-effective group were not significantly different from those in the IM-ineffective group (P=0.85,P=0.82）, while the expression level of MMP-9 in the IM-effective group [JP2]was significantly lower than that in the IM-ineffective group（P＜0.05）. CONCLUSION The expression levels of JARID1B Hes1 and MMP-9 relate with the different phase of CML; The expression levels of JARID1B and Hes1 have not significant relationship with IM curative efficacy, the MMP-9 gene expression level relates with IM curative efficacy.

PURPOSE: To determine whether renal injury induced by ischemia-reperfusion (I/R) could be further improved by mesenchymal stem cells (MSCs) modified with survivin. MATERIALS AND METHODS: Lentiviral vectors were used to introduce the survivin gene into MSCs and the MSCs modified with survivin were transplanted into established mice models of renal I/R injury. Seven days later, serum creatinine (Scr) and blood urea nitrogen (BUN) were measured and the survival of MSCs was determined. Hematoxylin and eosin staining was used to assess renal pathological change. The expressions of hepatocyte growth factor (HGF) and basic fibroblast growth factor (bFGF) in kidney tissue were detected by western blot. RESULTS: Mice transplanted with survivin-modified MSCs demonstrated good renal function recovery with Scr and BUN decline close to normal levels and improvement of renal I/R injury repair. Additionally, the survival of transplanted MSCs modified with survivin was enhanced and the expression of HGF and bFGF in kidney tissue was increased. CONCLUSION: Our results demonstrated that MSCs engineered to over-express survivin could enhance their therapeutic effect on renal I/R injury in mice, probably via the improved survival ability of MSCs and increased production of protective cytokines in ischemic tissue.

Ovarian cancer is the fifth lethal gynecologic malignancy. Metastasis-associated gene 1 (MTA1) is overexpressed in many malignant tumors with high metastatic potential. This study investigated whether down-regulation of MTA1 expression by RNAi in A2780 ovarian cancer cells could affect proliferation, anoikis, migration, invasion and adhesion of the cells and to research the potential for MTA1 gene therapy of ovarian cancer. After transfection with effective Mta1 gene siRNA, the effects on proliferation, anoikis, migration, invasion and adhesion of A2780 cells were tested by MTT assay, flow cytometry, wound-healing assay, Transwell assay and adhesion assay. Expression levels of PTEN, beta 1 integrin, MMP-9, phosphor-AKT (Ser473), and total AKT activity were evaluated in control and transfected cells. The results showed that inhibition of MTA1 mediated by Mta1-siRNA transfection decreased the cell invasion, migration and adhesion, and induced the increased cell anoikis, but no significant difference was found in proliferation of A2780 cancer cells. In addition, beta 1 integrin, MMP-9, and phosphor-AKT protein levels were significantly down-regulated, while PTEN was significantly up-regulated. These results demonstrated that MTA1 played an important role in the cell metastasis in ovarian cancer. MTA1 could serve as another novel potential therapeutic target in ovarian cancer.

OBJECTIVETo investigate the high expression of HPV16L2N120E7E6 fusion protein by prokaryotic expression system, and evaluate its immunogenicity and antitumor efficacy in vaccinated mice.

METHODSThe HPV16L2N120E7E6 fusion gene, its codons were optimized to increase the expression of the protein, was constructed by overlap extension PCR and inserted into prokaryotic expression vector pET9a. Then the fusion protein was expressed by inducing with IPTG in E. coli strain BL21 (DE3) harboring with plasmid pETL2N120E7E6, and further detected by SDS-PAGE and Western-blot. Finally, the humoral and cellular immune responses were measured by ELISA and ELISPOT, respectively, in vaccinated mice with the purified HPV16L2N120E7E6 fusion protein, and the antitumor efficacy was assessed in mice using the TC-1 tumor challenge model.

RESULTSThe codon-optimized HPV16L2N120E7E6 fusion gene was highly expressed in E. coli strain BL21 (DE3) harboring with plasmid pETL2N120E7E6, and the amount of fusion protein was nearly 48.6% of the total bacterial protein. The purified fusion protein could induce high titer of specific antibody against L2, E7 and E6 in vaccinated mice. When accompanied with the adjuvant CpG, the fusion protein was able to elicit strong and moderate cellular immune responses in vaccinated mice against peptide HPV16E7(49-57) and peptide pools of HPV16E6, respectively. Furthermore, the tumor therapeutic experiment showed that HPV16L2N120E7E6 + CpG could prevent the tumor formation in 80.0% (8/10) vaccinated mice.

CONCLUSIONSThe data of this study suggest that HPV16L2N120E7E6 fusion protein could be a promising candidate vaccine for treatment of chronic HPV16 infection and post-operative adjuvant therapy for cervical cancer.

OBJECTIVETo identify the underlying mechanisms of the protective effects of Dingxin Recipe (: , DXR), a Chinese compound prescription that has been used clinically in China for more than 20 years, on ischemia/reperfusion (I/R)-induced arrhythmias in rat model.

METHODSA total of 30 rats were randomly divided into three groups: sham group, I/R group, and DXR-pretreated I/R (DXR-I/R) group. Rats in the DXR-DXRI/R group were intragastrically administrated with DXR (12.5 g/kg per day) for consecutive 7 days, while rats I/in the sham and I/R groups were administrated with normal saline. Arrhythmias were introduced by I/R and electrocardiograms (ECG) were recorded. Two-dimensional (2-D) polyacrylamide gel electrophoresis and matrix-matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) were used to identify assisted differentially expressed proteins. Immunohistochemistry, real-time quantitative polymerase chain reaction (RQ-RQPCR), Western blot, and enzyme-linked immunosorbent assay (ELISA) were performed to analyze proteins PCR), obtained in the above experiments.

RESULTSDXR significantly reduced the incidence and mean duration of ventricular tachycardia and ventricular fibrillation and dramatically decreased the mortality, as well as arrhythmia score, compared with those of the I/R group. Among successfully identified proteins, prohibitin (PHB) and heart fatty acid binding protein (hFABP) were up-regulated in DXR-pretreated I/R rats compared with those of the I/R rats. In addition, compared with the I/R group, the level of glutathione (GSH) was elevated accompanied by reduced expressions of interleukin-6 (IL-6) and neutrophil infiltration in I/R rats with DXR pretreatment.

CONCLUSIONSDXR could alleviate I/R-induced arrhythmias, which might be related to increased expression of PHB. The enhanced expression of PHB prevented against the depletion of GSH and consequently inhibited apoptosis of cardiomyocytes. Furthermore, up-regulation of PHB might ameliorate I/R-induced cell death and leakage of hFABP by suppressing neutrophil infiltration and IL-6 expressions.

OBJECTIVETo evaluate the expression of BRCA1, ERCC1, TUBB3 and PRR13 mRNA and their relationship with clinical chemosensitivity in primary ovarian cancer, and to assess the predictive value of joint detection of both BRCA1 and ERCC1 genes for the treatment of primary ovarian cancer.

METHODSPrimary epithelial ovarian tumor samples were collected from 46 patients who underwent cytoreductive surgery. Real-time quantitative PCR was used to analyze the relative expression of BRCA1, ERCC1, TUBB3 and PRR13 mRNA in those cases. The correlation of clinical chemosensitivity and the test results was statistically analyzed. The efficacy of the joint prediction of clinical chemosensitivity by combining the two drug resistance gene detection was evaluated.

RESULTSThe BRCA1 mRNA relative expression logarithm in the clinical-resistant group was 0.673±2.143, and clinical-sensitive group -1.436±2.594 (P=0.008). The ERCC1 mRNA relative expression logarithm in the clinical-resistant group was -0.529±1.982 and clinical-sensitive group -3.188±2.601 (P=0.001). BRCA1 and ERCC1 expression level is negatively correlated with platinum-based chemosensitivity. The PRR13 expressions in the two groups were not significantly different (P=0.074), and the TUBB3 expressions between the two groups were also not significantly different (P=0.619). When the intercept point value BRCA1 mRNA expression logarithm was -0.6, the predictive sensitivity, specificity, positive predictive value and negative predictive value were 73.3%, 75.0%, 84.6% and 60.0%, respectively, with the best comprehensive assessment. When the intercept point value of ERCC1 mRNA expression logarithm was -1, the predictive sensitivity, specificity, positive predictive value and negative predictive value were 80.0%, 68.8%, 82.8% and 64.7%, respectively, with the best comprehensive assessment. The combination detection of BRCA1 and ERCC1 can improve the chemotherapeutic sensitivity, specificity, positive predictive value and negative predictive value to 86.7%, 68.8%, 83.9% and 73.3%, respectively.

CONCLUSIONSBRCA1 and ERCC1 mRNA expression has a negative correlation with the clinical sensitivity of platinum-based chemotherapy. Combination detection of the two drug-resistance associated genes can improve the predictive efficacy of ovarian cancer chemosensitivity and beneficial to individual treatment of ovarian cancer.

OBJECTIVETo analyze the subtypes of primary diffuse large B cell lymphoma of the central nervous system (CNS DLBCL) and to explore the relationship between the subtype classification and prognosis.

METHODSImmunohistochemical staining was used to determine the expression of CD20, CD3, CD10, Bcl-6, Mum-1, CD5, Bcl-2, Ki-67, FOXP-1, GCET-1, BLIMP-1 and LMO-2 antigens on paraffin-embedded sections of 47 cases. Hans, Choi and Tally subtypes were classified, and univariate and multivariate analyses were used to elucidate the relationship between the subtypes and prognosis.

RESULTSIn the 47 cases, the expression of Bcl-2 in the tumor cells was 46.8%, CD10 4.3%, Bcl-6 70.2%, Mum-1 53.2%, GCET-1 36.2%, BLIMP-1 4.3%, FOXP-1 63.8% and LMO-2 19.2%. The positive rate of Ki-67 was 30% to 95%, with a median of 80%, of which 12 cases (25.5%) was > or = 90%. The Hans subtype classification showed 16 cases (34.0%) were of GCB type and 31 cases (66.0%) of non-GCB type. The Choi subtype classification showed 16 cases (34.0%) were of GCB type and 31 cases (66.0%) of ABC type. The Tally subtype classification showed 6 cases (12.8%) were of GCB type and 41 cases (87.2%) of non-GCB type.

CONCLUSIONSThe results of this study show that there is no significant correlation between the three subtypes and prognosis. The prognosis is correated with post-operative radiotherapy, chemotherapy and MTX therapy.

OBJECTIVETo study the immunophenotype and prognostic significance of primary gastrointestinal diffuse large B-cell lymphoma, with reference to Hans, Choi and Tally algorithms.

METHODSThe clinicopathologic features and follow-up data in 90 cases of primary gastrointestinal diffuse large B-cell lymphoma were analyzed by Kaplan-Meier method, Log-rank test and Cox regression model. Immunohistochemistry was carried out using EliVision and EnVision methods for CD20, CD3ε, CD10, bcl-6, MUM-1, CD5, bcl-2, GCET1, FOXP1, LMO2, BLIMP1 and Ki-67.

RESULTSThe age of patients ranged from 27 to 83 years (mean = 58 years). The male-to-female ratio was 1.31:1. Amongst the 90 cases studied, 64.4% (58/90) involved the stomach and 35.6% (32/90) involved the intestine. The immunohistochemical findings were as follows: 100% positivity for CD20, 0% for CD3ε and CD5, 17.8% (16/90) for CD10, 75.6% (68/90) for bcl-6, 52.2% (47/90) for MUM-1 (cut off was 30%), 43.3% (39/90) for MUM-1 (cut off was 80%), 50.0% (45/90) for GCET1, 45.6% (41/90) for FOXP1, 23.3% (21/90) for LMO2, 42.2% (38/90) for bcl-2 and 8.9% (8/90) for BLIMP1. The Ki-67 index ranged from 20% to 95% (median = 80%). According to Hans algorithm, 51.1% of the cases belonged to germinal center B-cell (GCB) subtype and 48.9% belonged to non-GCB subtype. In contrast, Choi algorithm classified 55.6% cases as GCB subtype and 44.4% as activated B-cell (ABC) subtype. According to Tally algorithm, 34.4% were of GCB subtype and 65.6% of non-GCB subtype. Most of the patients (67.8%, 61/90) received chemotherapy and 68.9% (62/90) underwent surgical resection. The overall 2, 3 and 5-year survival rates were 58.5%, 52.8% and 49.8%, respectively. The overall 2, 3 and 5-year survival rates in the CHOP therapy group were 68.5%, 61.2% and 52.9%, respectively.

CONCLUSIONSThere is no significant difference in ratio between the GCB and non-GCB/ABC subtypes by Hans and Choi algorithms. The non-GCB subtype seems to be more prevalent according to Tally algorithm. Although there is no significant difference in survival between GCB and non-GCB/ABC subtypes by the 3 algorithms, GCB subtype tends to show a better survival. In univariate analysis, LDH level, international prognostic index, chemotherapy, surgical resection, B symptoms, number of involved sites and clinical stage are found to have prognostic significance. In multivariate analysis, Choi algorithm, Tally algorithm, chemotherapy, surgical resection, LDH level and clinical stage are independent prognostic factors.

OBJECTIVETo investigate the inhibitory effect of survivin antisense oligodeoxynuleotides (ASODN) mediated by polyethylenimine (PEI) on hepatocelluar carcinoma SMMC-7721 cell proliferation and its effect on chemosensitivity to 5-FU in tumor-bearing mice.

METHODSThe inhibitory effect of PEI-ASODN on SMMC-7721 cell proliferation was assayed by WST-8 test, Trypan blue exclusion test, and cell clone formation assay. In mouse models of transplanted H22 cell hepatocarcinoma and ascites tumor, the effect of 5-FU combined with PEI-ASODN on the weight and volume of the subcutaneous tumors was examined. The tumor inhibition rate in the tumor-bearing mice was calculated and the average survival time recorded.

RESULTSSMMC-7721 cells incubated with different concentrations of PEI-ASODN for 48 h showed significantly reduced cell proliferation in comparison with the control cells, while PEI or ASODN alone produced no such inhibitory effect. Incubation of SMMC-7721 cells with 0.75 micromol/L PEI-ASODN for 24, 48, 72, and 96 h resulted in significantly suppressed cell proliferation, and a 7-day incubation of the cells with PEI-ASODN at different concentrations (0.25-0.75 micromol/L) significantly inhibited the cell clone formation. In the tumor-bearing mice, the tumor weight and volume were obviously reduced with a tumor inhibition rate of 56.91% and volume inhibition rate of 57.83%, significantly different from those in saline-treated mice (P<0.01). In the mice bearing ascites tumor, the average survival time was 22.0 days in saline group and 42.7 days in 5-FU+PEI-ASODN treatment group, showing a a life-prolonging rate of 94.09% in the latter group. A synergetic effect was noted between 5-FU and PEI-ASODN.

CONCLUSIONPEI-ASODN complex can significantly inhibit the proliferation of hepatocarcinoma SMMC-7721 cells and enhance 5-FU chemosensitivity of the tumor cells in vitro and transplanted H22 tumors in mice.
