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 angiogenic effect of leptin on grainy fat transplantation. Methods Grainy fat was obtained from the Wistar rat subcutaneous tissue in the abdomen. It was then mixed with 0.9 % NS and 20 ng/ml leptin and transplanted in the head subcutaneously. The transplanted tissue was taken out after 10, 20 and 40 days and was stained with AKP histochemistry and actin immunohistochemistry. The microvessel density was measured by medical imagine analysis system. The data were analyzed with SPSS software. Results The values of microvessel density in leptin groups were 0.12 ?0.04?m 2/?m 2 after 10 days and (6.83?1.86)?10 -2 ?m 2/?m 2 after 20 days. This was obviously high as compared with (1.49?0.88)?10 -2 ?m 2/?m 2 and (4.32?2.11)?10 -2 ?m 2/?m 2 in saline groups in the same observing periods ( P

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.

Objective To study Chinese medicine and Western medicine preventing the anaphylaxis of ionic-type radiography agent,to solve the anaphylaxis in brain enhancment CT.Methods Eight hundred and forty cases have been diagnosed in brain enhancement CT at our hospital,from Fed.1995 to May 2000.Results Chinese medicine,ginger,pinellia and hormone medicine were all useful in preventing the anaphylaxis of ionic-type radiography agent in brain enhancement CT.Conclusion Chinese medicine:ginger and pinellia could prevent the anaphylaxis of ionic-type radiography agent.

Objective To evaluate the possibility and efficiency of early lung cancer screening using low-dose spiral CT,and to investigate the effects of prognosis of lung cancer. Methods 3005 routine chests check-up were carried on the low-dose prospect research of the SHIMADZU 7800 TX spiral CT. According to the result by tracing and long-term CT follow-up based on the baseline screening, biopsy or surgical excisions were recommended in "malignant change" or enlarged nodules. Two doctors separately interpreted all the images blindly.Results 29.9 rate of nodules in all of cases were detected. Smoking group was 1.3 times incidence of non-smoking. A whole incidence of lung cancer was 1.2, including 2.9 in people at high risk of lung cancer and 0.9 in common people. The sensitivity and specificity of lung cancer screening using low-dose spiral CT were 82.9 and 88.8 respectively, and the diagnostic accuracy of lung cancer screening in diameter of nodules less than 10 mm was high than in ones more than 10 mm. Histologically, 33 non-small cell lung cancers (19 stageⅠ, 10 stageⅡand 4 stageⅢ), 2 small cell lung cancers and 1 scar carcinoma were proved based on baseline screening by biopsy or surgery. By the end of 2007, the average survival for clinical stageⅠlung cancer was more than 4 years, clinical stageⅡwas 2～3 years and clinical stageⅢ was 1～2 years. Conclusion Low-dose spiral CT is of high sensitive and specificity in detecting early lung cancer. Preliminary screening study indicates that low-dose spiral CT can greatly improve the likelihood of detection for early lung cancer and situation of survival.

Objective To study the application of the array comparative genomic hybridization (Array-CGH) for the detection of chromosomal disorders in newborns.Method The Array-CGH technique was used to analyze the whole genome of the patients who were suspected of chromosomal disease in neonatal ward of our hospital from January to December in 2014,and further verification in genomic unbalanced ectopia was carried out by FISH (fluorescence in situ hybridization,FISH).Result Among 514 patients,104 were found carrying chromosomal abnormalities with a detection rate of 20.2％.The most common chromosomal disease is the Down syndrome syndrome (24 cases),followed by the chubby Willy and Angel syndrome(17 cases),while the Wolf-Hirschhorn syndrome in 5 cases,Williams syndrome in 5 cases and the Criduchat syndrone in 5 cases.The results of FISH were consistent with Array-CGH.Conclusion The technique of Array-CGH can be used to scan the whole genome of children with unknown disease.As a high-throughput and rapid research method,this technique has important clinical significance in the screening of chromosomal diseases.

Objective To investigate celecoxib self-microemulsifying drug delivery system (CXB-SMEDDS) that was developed to increase the dissolution rate and oral bioavailability of celecoxib.Methods The formulation of CXB-SMEDDS was optimized by pseudo-ternary phase diagrams analysis.The appearance, morphology, particle size distribution and in vitro drug release behavior of CXB-SMEDDS were investigated after diluted by water.The bioavailability of CXB-SMEDDS was determined by oral administration to rats compared with CXB suspension.Results An optimized formulation was selected: Medium chain triglycerides as oil phase, Tween 20 as surfactant, Transcutol HP as cosurfactant.The ratio of oil phase, surfactant and cosurfactant was 2∶9∶9.Upon mixing with water, CXB-SMEDDS formed a clear and transparent microemulsion solution with homogeneous small spherical under transmission electron microscopy.For particle size of CXB-SMEDDS was found to be (57.6±14.2) nm.The in vitro dissolution test indicated a significant improvement in release characteristics of CXB.The AUC of CXB-SMEDDS and CXB suspension were (5.54±0.94) and (3.32±0.59) mg·L-1·h, respectively.The relative bioavailability was 166.9%.Conclusion The SMEDDS can significantly increase celecoxib dissolution in vitro and bioavailability in vivo.
