The Notch signaling pathway is a highly conserved classical developmental pathway,which plays a critical role in cell-fate decision by modulating proliferation, differentiation and apoptosis. There is increasing evidence that abnormal Notch pathway is correlated with occurrence and development of many tumors. Notch signaling plays dual roles in a wide range of B-cell malignancies. It serves as either an oncogene or a tumor suppressor. Notch signaling pathway may be a novel target for B-cell malignancies therapy.

Accurate imaging of lymphoma is essential for optimal management. Positron emission tomography(PET-CT),by providing both anatomic and functional information,is fundamentally altering staging,monitoring of response,response assessment,and choice of treatment modality for lymphomas, including Hodgkin lymphoma. This imaging technique, when used carefully in conjunction with standard testing,increases the sensitivity of lesion detection, provides an opportunity to monitor the quality of response during treatment, permits separation of fibronecrotic scartissue from viable tumor, and adds prognostic information.PET-CT has become integral to modern lymphoma management, but as a relatively new diagnostic technique,it is still being studied and neither its full potential nor its major limitations are fully understood. Discussed herein are recent observations from clinical trials and single-center experiences with PET-CT to explore its advantages and limitations from a clinician’ s point of view.

Primary light-chain (AL) amyloidosis is a rare, fatal and clonal plasma cell dyscrasia. The bortezomib-based treatment has improved the survival of AL amyloidosis patients, but the prognosis of advanced patients is still poor. More effective novel agents are urgently needed. At the 62nd American Society of Hematology (ASH) Annual Meeting, the clinical data of a variety of new drugs (such as anti-CD38 monoclonal antibody, bcl-2 inhibitor combined with statins and CAEL-101, etc.) were reported.

Objective: To compare the biotype and genetic similarity between groups of commensal and pathogenic strains of candida species. Methods:Random amplified polymorphic DNA (RAPD) was used to analyse the type of Candida albicans. Results: 12 pathogenic isolates of Candida albicans, 3 commensal isolates of Candida abicans and 3 isolates of pathogenic non-albicans were obtained. The similarity coefficient of albicans with non-albicans was 51.7% by RAPD. Intra-candida similarity coefficient was more than 70%. Both the commensal and pathogenic isolates showed the genetically similar to C. albicans. Intro-isolate DNA polymorphism was observed by RAPD. Conclusion: Both the commensal and pathogenic groups contain a major cluster of genetically similar C. albicans isolates.

Objective To observe clinical effect of treating pelvic effusion with twenty five tastes podophyllum pill combined with antibiotics, microwave. Methods 182 cases patients with inflammatory pelvic effusion were randomly divided into two groups. The treatment group was treated with twenty five tastes podophyllum pill combined with antibiotics、microwave, and the control group was treated with antibiotics combined with microwave. The absorption, symptoms disappeared and cure situations of pelvic effusion were observed between control group and treatment group after treatment.Results The complete absorption, symptoms disappeared and cure situations of pelvic effusion in the treatment group was significantly higher than that of the control. The total effective rate of the treatment group was 100%, and the total effective rate of the control group was 87.5%, which has a significant difference (P<0.05) .Conclusion The treatment of twenty five tastes podophyllum pill combined with antibiotics, microwave on pelvic effusion is better than western medicine.

Objective:To explore the expression of GITR/GITRL in rheumatoid arthritis(RA)and its correlation with clinical features of the disease.Methods:Fifty three RA patients,35 osteoarthritis(OA)patients and 35 healthy volunteers were included in the study.The real-time-fluorescence quantitative PCR method was used to analyze the expression level of GITR/GITRL mRNA.Using fluorescence-activated cell sorting(FACS),the expression of GITR on CD4+CD25+ T cells in peripheral blood monouuclear cells(PBMC)was detected.The levels of Anti-CCP antibody,C-reactive protein(CRP),erythrocyte sedimentation rate(ESR)and rheumatoid factor(RF)of the RA patients were measured at the same time.Results:It was shown that the level of GITR/GITRL mRNA and the percentage of GITR+ T cells in the CD4+CD25+ T cell subpopulation[12.38?5.72/16.41?10.16,(28.12?16.85)%] were significantly higher than those of the OA group [9.59?5.87/12.09?7.53,(21.01?14.42)%,P

Objective To understand the clinical profiles of arthritis after human parvovirus B19(B19) infection.Methods Four cases were described and the clinical and laboratory characteristics were analyzed. Results The median onset age of the 4 patients(2 females and 2 males)was 34 years old.Typical clinical manifestations included joint symptoms,flu-like malaise and erythematous rash.Anti-Bl9 IgM antibodies were all positive in 4 patients.B19 DNA was detected in blood samples of 3.Other types of arthritis were excluded. No relapses were noticed after followed-up of 1～3 years.Conclusion The Anti-B19 lgM and B19 DNA should be detected in patients suffer from arthritis with unknown origin.

Objective:To elucidate the characterization of antigen-specific memory T cells from PPD~+ individuals after stimulation with BCG in vitro.Methods:PBMCs were isolated from PPD~ -/+ normal human peripheral blood and stimulated with BCG. The level of IFN-? in the culture supernatants was assayed by ELISA and the frequency of IFN-?-producinging cells was detected by ELISPOT. The subsets and frequency of cytokine-producing cells were determined at a single cell level by flow cytometry.Results:After stimulation with BCG, PBMCs from PPD~+ but not PPD~- individuals produced significantly high levels of IFN-? in culture supernatants detected by ELISA(P

AIM To set up the model of stom- effects of its treatment drugs. METHODS To ap-ach smooth muscle cells contraction and assess the ply the culture of isolated stomach fundus smooth muscle cells in rats in vitro and to obtain the mixture of stomach smooth muscle cells. The cells were examined with the Trypan blue dilution technology under microscope and the length of cells and the contraction rate of muscle cells were adopted to the evaluation index of effects. The change of cells in different time was observed and calculating the survival rate and time of cells. The selected neuro-medium and its antagonist, such as acetyl-choline chloride (ACh) and atropine, 5-HT and domperidone(Domp) , histamine( His) and diphen-hydramine(Diph) were added to the mixture cells so as to provoke irritant reaction observe the effects of drugs. RESULTS Obtaining cells in stomach fundus smooth muscle was more than 1 X 106 in each rat by this way, and the survival rate and time of cells was 95% and 2. 5 h. The contraction of cells was observed after adding ACh 5-HT or His ,and the effects of these agents were antag- onized by antagonist atropine, Domp and Diph respectively. The effects of maximum contraction of ACh in concentration 1?10-8 mol ? L-1 was 38%, and in 5-HT may exist two receptors, and the maximum rate was 20. 7% and 10. 5% respectively. The effective dose of contraction was 1 X 10-13 -1?10-10 mol ? L-1 induced by His, the contraction effects was significantly weakened in high of 1 ?10-10 mol ? L-1 and antagonized by Diph. CONCLUSION The smooth muscle cells by digesting stomach fundus smooth muscle of rats would be more than 95% survivors and survival time was more than 2. 5 h. ACh,5-HT and His could induce the contraction of smooth muscle cells, and the effects of contraction were antagonized by atropine, Domp and Diph respectively.
