Aggressive B-cell lymphoma is characterized by malignant behaviour and rapid progression.Patients are prone to drug resistance or relapse of disease.The 19th European Hematology Association (EHA)annual congress explored several aspects about aggressive B-cell lymphoma.PET-CT examination provided new tools for the indication of prognosis.The elevated dose of rituximab improved the outcome of elderly male patients.Novel drugs or methods including bortezomib,ABT-199,combined targeted therapy and CNS prophylaxis have shown encouraging results in various clinical trials which provide new hope for patients with aggressive B-cell lymphoma.

Hodgkin lymphoma (HL) originates from the lymphoid hematopoietic tissues and has a good treatment outcome with relatively high cure rate.Early stage HL is curable with abbreviated chemotherapy plus involved-filed radiotherapy or chemotherapy alone.However,patients with refractory or relapsed disease still lack effective treatment.In recent years,with the application of risk stratified treatment,novel drugs such as brentuximad vedotin,and PET-CT evaluation,significant progress has been made in prognosis and treatment of HL

Objective To investigate the efficiency of biology function of ITIH4 gene silenced by small interfering RNA (siRNA) on ovarian cancer.Methods The four pairs ITIH4 gene siRNA interference fragments(ITIH4-546,ITIH4-795,ITIH4-917 and ITIH4-1568) were designed respectively,and transfected into HO8910pm cells with ITIH4 mRNA high expression by liposomal method transiently.Quantitative PCR method was used to detect the ITIH4 mRNA expression in HO8910pm cells transfected with interference fragment.The ITIH4 917 was selected as the best silencing effect of siRNA interference fragment and then the recombinant plasmid expression vector pGPU6/GFP/Neo-shRNA-ITIH4-917 was constructed and transfected into HO8910pm cells.The stably transfected cells-pGPU6/GFP/Neo-shRNA-ITIH4-917-HO8910pm cells was obtained by screening of aminoglycoside antibiotics (G418).The experiment was divided into three groups,namely ITIH4-917 transfection group,the HO8910pm cell group transfected with pGPU6/GFP/Neo-shRNA plasmid (empty vector group),and the HO8910pm cell group transfected with pGPU6/GFP/Neo-shRNA-ITIH4-NC the plasmid (negative control group).Fluorescence quantitative reverse transcription(RT)PCR and western blot were used to detect the ITIH4 mRNA and protein expression.The cell proliferation,the cell cycle,colony formation of cells,cells migration and invasion in vitro were determined by using methyl thiazolyl tetrazolium (MTT),flow cytometry,colony formation assay and transmembrane (transwell) small chamber method [value represented by absorbance (A)],respectively.Results The fluorescent quantitative PCR results showed that the ITIH4 mRNA expression levels in ITIH4-917 HO8910pm cells was significantly lower than that in the control cells,the relative copy number was only 0.26 ± 0.15.Also the relative copy number of ITIH4 mRNA in ITIH4-917 transfection group cells was 0.34 ±0.10,it significantly lower than that in empty vector group (1.87 ±0.12,P =0.008) and negative control group (1.58 ±0.21,P =0.032) ; Western blot results showed that the ITIH4 relative expression levels of the protein in ITIH4-917 HO8910pm group cells,empty vector group and negative control group were 0.51,1.64 and 1.74,respectively,there were statistically significant differences (0.51 vs.1.64,P =0.012; 0.51 vs.1.74,P =0.014).MTT colorimetric assay showed that the proliferation of ITIH4-917 HO8910pm group cells was significantly faster than that in the empty vector group and negative control group,and there were statistically significant differences among them (P =0.001).The S ± G2/M phase cell ratio in ITIH4-917 HO8910pm group cells was 54.2％,which was significantly higher than that in the empty vector group or negative control group (26.3％ and 31.3％,respectively,all P ＜ 0.05).The colony formation rate (55.7 ± O.7) ％ in ITIH4-917 HO8910pm group cells was also significantly higher than that in empty vector group (29.7 ±0.9) ％ (P =0.037) and negative control group (31.4 ± 0.3) ％ (P =0.043).Migration and invasion experiments showed that cell migration in ITIH4-917 HO8910pm group cells was 0.40 ± 0.18,whicht was significantly higher than that in the negative control group or empty vector (0.30 ±0.03,P =0.031 ;0.25 ±0.03,P =0.028,respectively).Although the invasive ability of ITIH4-917 HO8910pm group cells (1.31 ±0.34) was higher than that in the control cells (1.05 ±0.68) and empty vector group (1.14 ±0.08),while there were not significant difference (P ＞ 0.05).Conclusion It would be to promote the cell doubling time and increase the migration capability in HO8910pm cells that ITIH4 expression was down-regulating by ITIH4 mRNA interference.

Objective To investigate the clinical therapeutic effect of Xuebijing injection for treatment of patients with ventilator-associated pneumonia (VAP).Methods A prospective study was conducted. Forty-eight patients with confirmed diagnosis of VAP requiring mechanical ventilation admitted into intensive care unit (ICU) of Hubei Provincial Hospital of Integrated Traditional Chinese and Western Medicine between May 2013 and September 2014 were enrolled. The patients were randomly divided into observation group (26 cases) and control group (22 cases) by random number table. All patients in both groups received western conventional treatment, and the patients in observation group were treated additionally with 50 mL Xuebijing injection intravenous drip twice a day, and control group received only routine western medicine, the therapeutic course in both groups being 7 days. The changes of white blood cell count (WBC), serum procalcitonin (PCT) levels and the clinical pulmonary infection score (CPIS) were observed, and the clinical therapeutic effect and 28-day prognosis were analyzed in both groups.Results After treatment for 7 days, the WBC, PCT levels and CPIS score were decreased compared with those before treatment in the two groups, and the degree of descent in observation group was more significant than that in the control group [WBC (×109/L): 9.16±1.62 vs. 12.03±2.34, PCT (μg/L): 0.17±0.04 vs. 0.28±0.69, CPIS score: 3.31±0.97 vs. 4.23±1.15, allP < 0.05]. The effective rate of observation group was higher than that of the control group [84.6% (22/26) vs. 54.5% (12/22), P < 0.05], while the 28-day fatality rate in the observation group was lower than that of control group [11.5% (3/26) vs. 36.4% (8/22),P < 0.05].Conclusion The clinical therapeutic effect is good when patients with VAP is treated with addition of Xuebijing injection on the basis of conventional western medicine therapy, as the injection can improve the therapeutic efficacy and reduce the fatality rate.
