OBJECTIVE: To investigate the efficacy of chemotherapy combined with antivirals in adult T-cell leukemia/lymphoma (ATLL) patients and the prognostic factors. METHODS: Forty nine patients with previously treated or treatment-nave ATLL from January 2018 to January 2021 were included in our study. The patients were divied into two groups according to whether they received antiviral treatment, twenty-seven patients were treated with chemotherapy combined with antivirals, including thirteen patients treated with recombinant interferon alpha-2b and CHOP therapy, eight patients treated with zidovudine combined with CHOP therapy, and 6 patients treated with CHOP regimen combined with interferon and zidovudine. Twenty-two patients were treated with CHOP therapy. The changes of symptom, hematological parameters, lactic dehydrogenase, β2-microglobulin, and the Ki-67 positive rate were compared between the two groups before and after treatments. The clinical efficacy of chemotherapy combined with antiviral therapy for ATLL was evaluated. The antiviral effect was assessed by detecting HTLV-1 virus copy number, and prognostic factors were analyzed. RESULTS: The median follow-up time was 14 months. Compared with the patients treated with chemotherapy alone, the patients treated with chemotherapy combined with antivirals had lower tumor and virus loads, lower white blood cell count, lower lactate dehydrogenase level, lower β2-microglobulin lever, and lower Ki-67 positive rate (all P<0.05). The total effective rate of patients treated with chemotherapy combined with antivirals was significantly higher than those of patients treated with chemotherapy alone (63.0% vs 31.8%, P=0.035). The one-year overall survival (OS) rates of chemotherapy combined with antivirals groups and chemotherapy alone group were (74.1±2.9)％ and (40.9±2.1)％ (P=0.021), respectively. The one-year progress free survival (PFS) rates were (51.9±3.3)％ and (13.6±2.8)％ (P=0.017), respectively. Multivariable Cox regression analysis showed that HTLV-1 virus load (HR=7.518, 95%CI: 2.517-36.192, P=0.013) and antiviral therapy ［HR=5.617 (95%CI 1.803-11.293), P=0.027］ were independent prognostic factors for the long-term efficacy. CONCLUSION Addition of antivirals to chemotherapy can prolong PFS and OS in ATLL patients. HTLV-1 virus load and antiviral therapy are independent prognostic factors for ATLL patients.

Objective: To explore the effect of combination regimen of interferon alpha-1b, interleukin-2 and thalidomide (ITI regimen) on minimal residual disease (MRD) in patients with acute myeloid leukemia (AML) who were in hematologic remission but MRD-positive. Methods: Eighteen patients (17 from Tumor Hospital of Zhengzhou University and 1 from the First People's Hospital of Pingdingshan City) with AML admitted from July 2016 to June 2018, who were in hematologic remission but MRD-positive were treated with different doses of ITI regimen, and the MRD levels were monitored. Results: Among 18 patients who received a conventional dose of ITI regimen for 1 to 2 months, 7 patients had undetectable MRD, 3 had significant decrease in MRD levels, 3 had elevated MRD level and had hematologic recurrence. Three patients with elevated MRD level received a higher dose of ITI regimen, 2 of them turned to MRD negative and the other 1 patient had decreased MRD level. The total response rate was 72.2%, and the response rate in patients with MRD > 1.0% was 57.1% (4/7) , and that of patients with MRD < 1.0% was 81.8% (9/11) , respectively. Conclusion: The ITI regimen can reduce the MRD level of patient with AML who are in hematologic remission but MRD-positive. The therapeutic effect could be improved by a higher dose administration of ITI regimen, and therapeutic effect may be negatively correlated with MRD level before treatment.

OBJECTIVE: To explore clinical characteristics of sinonasal malignant melanoma and curative effect of the combined modality therapy. METHOD: Clinical data of 6 cases with sinonasal malignant melanoma was retrospectively analyzed. All patients received surgery and postoperative radiotherapy. In addition, 3 cases received postoperative chemotherapy which scheme was CDBT and bioimmunotherapy consisted of INF-α and IL-2 after surgery, of which, 2 cases received one cycle of preoperative chemotherapy. RESULT: Six cases were followed up. The survival time ranged from 15 months to 98 months. The average survival time was 62.7 months. Analyzed by direct method, the 1-year, 3-year and 5-year survival rates were 100%, 83% and 67% respectively. Three cases which received the combined modality therapy, of whch, 2 cases received preoperative chemotherapy have survived by now. CONCLUSION The combined modality therapy should be adopted in case of sinonasal malignant melanoma with operation indication. For the patients who can not be operated recently Postbiopsy, it was beneficial to improve the efficacy of therapy that one cycle of preoperative chemotherapy and bioimmunotherapy should be implemented.

OBJECTIVETo compare the effects of Bushen Jiedu Recipe (BJR) and Jianpi Jiedu Recipe (JJR) containing plasma on dendritic cells (DCs) of chronic hepatitis B virus (HBV) infection patients under different immune states.

METHODSRecruited were 36 chronic HBV infection outpatients from First Affiliated Hospital of Hunan University of Traditional Chinese Medicine from April 2010 to January 2011. They were assigned to the immune tolerance group (18 cases) and the immune clearance group (18 cases).Another 10 healthy subjects were recruited as the healthy control group. Their anticoagulated peripheral venous blood was respectively collected. The peripheral blood mononuclear cells (PBMCs) were isolated and further extracted for incubating DCs. The DCs were intervened by BJR and JJR containing plasma. The morphology of DCs was identified. The expressions of CD1alpha, CD80, CD86, and HLA-DR were detected. The level of interferon-alpha (IFN-alpha) in the supernatant was observed by ELISA.

RESULTSThe CD80 expression level was lower in the immune clear group than in the healthy control group before intervention (P < 0.05). The expression levels of CD80, CD86, and HLA-DR were lower in the immune tolerance group than in the healthy control group before intervention (P < 0.05).The IFN-alpha expression level was lower in the immune tolerance group and the immune clearance group than in the healthy control group before intervention (P < 0.05). The expression levels of CD80, HLA-DR, and IFN-alpha were lower in the immune tolerance group than in the immune clearance group before intervention (P < 0.05). Compared with the same group before intervention, the CD80 expression significantly increased in each treatment group (P < 0.05). After intervention the expression levels of CD80 and HLA-DR were higher in the immune tolerance group than in the immune clearance group in the same time phase, and the CD86 expression level was higher in the BJR group than in the immune clearance group in the same time phase, showing statistical difference (P < 0.05).

CONCLUSIONSThe middle dose BJR and the small dose JJR both could promote the recovery of DCs in chronic HBV infection patients. Besides, BJR showed more prominent effects on the function of DCs in chronic HBV infection patients in the immune tolerance stage.

To evaluate the efficacy and safety of interferon-alpha-2b (IFN-&alpha;-2b) in polycythemia vera patients(PV patient) with or without post-polycythemic myelofibrosis (post-PV MF), 30 patients with mutated JAK2V617F were enrolled in this study, from which 29 patients were evaluable. The percentage of mutated JAK2V617F allele (V617F%) was evaluated by real-time polymerase chain reaction (RT-PCR) before and after treatment with IFN-&alpha;-2b. The correlation of V617F allele burden with the major clinical outcomes was studied. Adverse effects appeared in patients was observed. The results showed that the median follow-up was 24 (12 - 42) months for 29 evaluable patients. Complete hematologic response was achieved in 10%, 48%, 72% and 78% of patients after treatment for 6, 12, 24 and 36 months respectively. The detection of V617F allele burden revealed that the molecular remission of patients (V617F%) was achieved in 41%, 76%, 89% and 89% after treatment for 6, 12, 24 and 36 months respectively. Molecular complete remission (JAK2V617F undetectable) was achieved in 4 patients, lasted from 6 to 12 months after IFN-&alpha;-2b discontinuation. The decrease of V617F% in patients with post-PV MF was significantly higher than that in patients without post-PV MF (53 ± 18% vs 32 ± 22%, respectively; p = 0.031) after treatment for 12 months. PV patients had a good tolerance to IFN-&alpha;-2b. It is concluded that IFN-&alpha;-2b can decrease the mutated V617F allele burden. Patients with PV, especially with post-PV MF, can achieve molecular remission after treatment with IFN-&alpha;-2b.

OBJECTIVETo investigate the possible mechanism of action of tripterygium glycosides (TG) for treatment of Behcet's disease (BD) through observing its effect on serum levels of interleukin-1beta (IL-1beta), interleukin-2 (IL-2), tumor necrosis factor alpha (TNF-alpha) and interferon-gamma (IFN-gamma).

METHODSThirty primarily treated BD patients (BD group) were treated with TG 30 mg/d orally for 3 months, and a control group consisting of 30 healthy persons was set up. Serum levels of IL-1beta, IL-2, TNF-alpha and IFN-gamma were detected by radio-immunosorbent assay (RIA) before and after treatment respectively. And the outcomes were analyzed in combining with the clinical status of patients as well as related indices as erythrocyte sedimentation (ESR) and C-reactive protein (CRP).

RESULTSSerum levels of IL-1beta, TNF-alpha, IFN-gamma in the BD group were evidently higher (P < 0.05) than those in the control group, they all lowered significantly after 3-month TG treatment, from 10.72 +/- 1.84 microg/L, 6.64 +/- 1.05 microg/L and 8.93 +/- 1.23 microg/L to 5.71 +/- 1.04 microg/L, 4.27 +/- 0.76 microg/L and 3.44 +/- 0.72 microg/L, respectively (P < 0.05), while level of IL-2 in the BD group was insignificantly different before treatment to that in the control (though showed an increasing trend) and was unchanged after treatment (P > 0.05). TG treatment showed the effectiveness of markedly effective in 10, effective in 16 and ineffective in 4 BD patients, with the total effective rate of 86.6%. Besides, ESR and CRP levels were evidently decreased in BD patients after treatment (P < 0.05).

CONCLUSIONTG may treat BD by way of regulating the levels of IL-1beta,TNF-alpha and IFN-gamma.

AIMTo observe the changes of MMP-2, 9 level on atherosclerosis in experimental rats by treatment of 2,3,4',5-tetrahydroxystilbene-2-0-beta-D glucoside (TSG) and to investigate the mechanism of TSG in stabilizing plaque and anti-atherosclerosis.

METHODSThe atherosclerosis model of rat was made by feeding high grease food and injecting VitD3. Sixty male SD rats were randomly divided into six groups: control, Simvastatin, model and TSG 120 mg x kg(-1) x d(-1), TSG 60 mg x kg(-1) x d(-1) and TSG 30 mg x kg(-1) x d(-1). After 12 weeks, several aorta were randomly tested, model and TSG 120 mg x kg(-1) x d(-1), TSG 60 mg kg(-1) x d(-1) and TSG 30 mg x kg(-1) x d(-1). After 12 weeks, several aorta were randomly tested, model made was successful when we found plaque. And after six weeks treating, the mRNA expressions of MMP-2 and MMP-9 were measured by RT-PCR. The activities of MMP-2 and MMP-9 were measured by Western blot. The levels of CRP, IL-6 and TNF-alpha in serum were measured in biochemical method.

RESULTSData of the study demonstrated that the level of TNF-alpha, IL-6, CRP, MMP-2 and MMP-9 were remarkably decreased by TSG60, 120 mg x kg(-1) x d(-1) groups, which showed a dose-dependent effect.

CONCLUSIONTSG has the effect of anti-atherogenic and stabilizing plaque on the experimental rats with atherosclerosis, which are induced by the high cholesterol feeding and VitD3 injecting. The effect of TSG seems to be closely involved in regulating the expressions of MMP-2 and MMP-9, and inhibiting inflammation.

OBJECTIVETo investigate the effect of bortezomib on prophylaxis of acute graft-versus-host disease (aGVHD) after mouse allogeneic-bone marrow transplantation (allo-BMT) and its mechanism.

METHODSC57BL/6 (H-2(b)) mice were used as donors and BALB/c (H-2d+) mice as recipients. After allo-BMT, the BALB/c mice were divided into 3 groups, ie. group A:BMT control, group B: BMT + early infusion of bortezomib (1 mg kg(-1) d(-1), day 0-3), group C: BMT + late infusion of bortezomib (1 mg kg(-1) d(-1), day 5-7). Clinical manifestations of aGVHD, pathohistological changes, survival rate and levels of recipients H-2(b) cells detected by flow cytometry in the recipient mice were observed. Monodirectional mixed lymphocyte culture (MLC) system was established ex vivo and different concentrations of bortezomib (0, 2, 4, 8 nmol/L) were added to the system. The viability of the cells was detected by CCK-8 assay and cells apoptosis by flow cytometry. The concentrations of IL-2, IFN-gamma, TNF-alpha in the supernatant were detected by enzyme-linked immunosorbent assay (ELISA).

RESULTSThe mice in group A developed typical aGVHD and all died of aGVHD within 3 weeks after transplantation, with a median survival time of (16.1 +/- 2.5) d. The symptoms of aGVHD was milder in group B than in group A, and the median survival time was significantly longer. The 60-day survival rate in group B was 70%, being significantly higher than that in other two groups(P<0.05). The mean value of donor-derived cell (H-2(b) cells) in group B was (98.1 +/- 1.1)% at 60 days. The symptoms of aGVHD was significantly severer in group C than in group A, and the median survival time was shorter. Bortezomib inhibited the cells viability in MLC system in a dose-dependent manner. After treated with 8 nmol/L bortezomib for 24 h, the inhibition ratio of cells viability was (41.4 +/- 6.0)%. The cell apoptosis rate increased gradually with bortezomib treatment for 12 h, 24 h and 36 h. After treated with 8 nmol/L bortezomib for 36 h, the apoptosis rate was (62.8 +/- 7.0)%. After treated for 24 h, the levels of IL-2, IFN-gamma and TNF-alpha in the supernatant were decreased.

CONCLUSIONSBortezomib administered immediately after allogeneic BMT can prevent aGVHD, improve the survival rate and have no influence of engraftment in the recipient mice. Delayed administration of bortezomib results in acceleration of aGVHD-induced mortality. Its mechanism maybe inhibition of the lymphocyte viability, increase of the cells apoptosis rate, and inhibition of secretion of IL-2, IFN-gamma, and TNF-alpha.

OBJECTIVETo observe the effect of Spleen-invigorating Prescription (SIP) on dendritic cell function in patients with chronic hepatitis B.

METHODSA total of 60 patients with chronic HBV of Pi-deficiency syndrome type were enrolled and randomized to 2 groups, 30 in each group. Patients in the control group were given intramuscular injection with human interferon alpha 1b, 3 times a week, while those in the treated group were given orally with SIP twice a day, the therapy lasted for 6 months. Dendritic cells (DCs) were isolated from peripheral blood and cultured, then the expression of surface markers, HLA-DR, CD86, CD80, CD40, CD14 and CD11c were detected before and after treatment by flow cytometry, and the function of DCs was also evaluated by mixed lymphocyte reaction (MLR) determination once before treatment and once after treatment.

RESULTSThe expressions of DCs' surface CD86, CD80, CD40 and CD11c in the treated group were higher (P < 0.05, P < 0.01) and the changes of stimulating index, IFN-gamma and IL-12 were superior in the treated group to those in the control group (P < 0.05).

CONCLUSIONSSIP can significantly improve DC's function, so, one of mechanisms of SIP in improving clinical efficacy may be the regulation of immune function.
