ABSTRACT

Objective: To investigate the expression of Bcl-6 in newly diagnosed and young patients with diffuse large B cell lymphoma (DLBCL), and to further explore its clinical significance in young DLBCL patients with Myc positive expression (Myc+) or Bcl-2 and Myc positive expressions (Bcl-2+Myc+). Methods: Immunohistochemical (IHC) staining was used to detect the expressions of Bcl-6, Myc and Bcl-2 in 116 newly diagnosed and young patients with DLBCL, and the complete clinical and pathological data were collected. The relationship between the expression levels of Bcl-6 protein and the prognosis of young DLBCL patients with Myc+ and Bcl-2+Myc+ was retrospectively analyzed. Results: There was no significantly correlation between the expression of Bcl-6 alone and the prognosis of young DLBCL patients (P > 0.05). However, for the DLBCL patients with Myc+, the prognosis in Bcl-6 negative (Bcl-6–) group was worse than that in Bcl-6 positive (Bcl-6+) group (P < 0.05). Furthermore, the multivariate COX regression analysis showed that Bcl-6–Myc+ expression was a significant independent factor of adverse prognosis except for the international prognostic index (IPI) (P < 0.05). Meanwhile, the prognosis of DLBLC patients with Bcl-6–Bcl-2+Myc+ was significantly worse than that of the patients with Bcl-6+Bcl-2+Myc+ (P < 0.05). Conclusion: Bcl-6 negative expression can increase the risk of poor prognosis in young DLBCL patients with Myc+ or Bcl-2+Myc+.

ABSTRACT

Cancer immunotherapy uses the host′s immune system to mobilize immune cells to rec-ognize and eventually eliminate cancer cells .At present, studies in terms of cancer immunotherapy mainly focus on programmed cell death protein 1/programmed death-ligand 1 (PD-1/PD-L1) antibody, cytotoxic T-lymphocyte-associated protein 4 ( CTLA-4 ) antibody, chimeric antigen receptor T-cell immunotherapy (CAR-T), T cell receptor Immunotherapy (TCR-T), etc.Despite the fact that cancer immunotherapies elicit unprecedented durable responses in clinical therapy , they appear to be ineffective to some patients .In addition, some responders relapse and show resistance to immunotherapies even if their symptoms are re -lieved for a time .Resistance to cancer immunotherapy can be categorized into primary , adaptive and ac-quired, which can occur in every stage during the process of anti-tumor response.In this review, we discuss the known mechanisms of resistance and provide a rationale for the use of combination therapy to overcome resistance.

ABSTRACT

OBJECTIVE:To investigate the effects of Astragalus injection combined with Salmeterol propionate powder inhala-tion on pulmonary function,cytokines and blood rheology indexes of Chronic obsrnctine pulmonary disease (COPD) patients. METHODS:104 COPD patients were divided into observation group and control group according to the randorn number table meth-od,with 52 cases in each group. Control group was given routine symptomatic treatment+Salmeterol propionate powder inhalation 1 dose,bid;observation group was additionally given Astragalus injection 30 ml added into 5% Glucose injection 250 ml,ivgtt, qd,on the basis of control group. Treatment course of 2 groups lasted for 2 weeks. Clinical efficacy,pulmonary function indexes [forced expiratory volume in one second(FEV1),forced vital capacity(FVC),FEV1/FVC],CRP,cytokine [IL-6,IL-8,TNF-α] levels,blood rheology indexes (whole blood high-shear viscosity,whole blood low-shear viscosity,fibrinogen,hematokrit and plasma viscosity),and the occurrence of ADR were observed in 2 groups. RESULTS:The total effective rate of observation group (94.23%)was significantly higher than that of control group(75.00%);compared with before treatment,FEV1,FVC and FEV1/FVC of 2 groups were significantly increased after treatment,and those of observation group were significantly higher than those of control group;CRP,IL-6,IL-8 and TNF-α of 2 groups were significantly decreased,and those of observation group were signifi-cantly lower than those of control group. The whole blood high-shear viscosity,whole blood low-shear viscosity,fibrinogen,hema-tocrit and plasma viscosity of observation group were decreased significantly after treatment,and the observation group was signifi-cantly lower than the control group,with statistical significance(P<0.05). No significant ADR was found in 2 groups. CONCLU-SIONS:Astragalus injection combined with Salmeterol propionate powder inhalation is significantly effective for COPD,improves pulmonary function of patients,improves micro inflammatory state and decreases blood rheology indexes with good safety.

ABSTRACT

OBJECTIVE:To investigate the therapeutic efficacy of edaravone combined with citicoline sodium on acute cere-bral infarction and its effects on the levels of oxidative stress and inflammatory factors. METHODS:108 patients with acute cere-bral infarction were randomly divided into edaravone group(single group)and edaravone+citicoline sodium group(drug combina-tion group),with 54 cases in each group. Based on routine treatment,single group was given Edaravone injection 30 mg added in-to 100 ml 0.9% Sodium chloride injection intravenously,bid,used up within 30 min each time;drug combination group was addi-tionally given Citicoline sodium injection 0.5 g added into 250 ml 0.9% Sodium chloride injection intravenously,qd,on the basis of single group. Treatment course of 2 groups lasted for 2 weeks. NIHSS,HDS,Barthel index,oxidant stress indicator and inflam-matory factors were compared between 2 groups before and after treatment. RESULTS:After treatment,the effective rate of NI-HSS in drug combination group was 81.48%,which was significantly higher than single group(53.70%),with statistical signifi-cance (χ2=9.511,P=0.002). HDS score and Barthel index of 2 groups were significantly increased after treatment,especially in drug combination group,with statistical significance(P<0.05). Compared with before treatment,contents of MDA and ET-1 in 2 groups were decreased significantly,while SOD activity and NO content were increased significantly;the inflammatory cytokines IL-6,IL-8,IL-12 and IL-16,TNF-α were all decreased gradually,with statistical significance (P<0.05);the improvement of each indicator in drug combination group was more significant than single group,with statistical significance(P<0.05). CONCLU-SIONS:Edaravone combined with citicoline sodium show good therapeutic efficacy in the treatment of acute cerebral infarction, can decrease the levels of oxidative stress and inflammation and promote the recovery of the neurological function and the daily liv-ing ability.
