Objective To explore the changes of tumor necrosis factor-?(TNF-?) in serum and cerebrospinal fluid(CSF) of children with acute lymphoblastic leukemia (ALL) and acute myelogenous leukemia(AML) and its clinical significance.Methods TNF-? in serum and CSF were measured by radioimmunoassay and CSF samples were obtained from 31 cases of childhood acute leukemia before treatment, on complete remission(CR), and continuous CR.Results Serum TNF-? was in ALL and AML before treatment [(24.35?4.84) pmol/L and(28.65?5.12) pmol/ L],which were significantly higher than those of healthy controls[(11.2 8? 1.69) pmol/L, P

Objective To evaluate the histocompatibility of novel manufactured xenogenic tendon matrix materials by an animal experimental study.Methods The study was conducted on 15 dogs,weighing 10-13 kg.The prepared xenogenic tendon matrix materials were implanted into the bilateral area of spine in dogs subcutaneously (experimental group),and the implantation of silicon served as control group.The animals were killed 14,30,60 days after surgery and the specimens were processed in laboratory to receive gross and histology observation.The histological sections were stained with hematoxylin-eosin and analyzed by light microscopy.Scores were assigned to the inflammatory process and statistically compared by two related samples with non-parametric test.Results All dogs survived well during the embedded test.There was no tissue necrosis,effusion or inflammation at all implantation sites in both groups during the test.The xenogenic implant materials promoted slight to moderate inflammation process after 14 days,with no statistically significant difference compared to the control.However,after 30 days,there was a regression of inflammation.After 60 days,it was observed the presence of well-organized connective tissue,and few inflammatory cells.Score evaluation of inflammation response at different time after operation of two groups showed no statistically significant difference (P＞0.05).Conclusions The new xenogenic tendon matrix materials are considered biocompatible with subcutaneous tissue.

Renal impairment is one of frequent and serious complications in patients with multiple myeloma (MM) and is associated with a higher incidence of infections and early death rate. The catalytic activity of Bence Jones proteins (BJP) affects the clinical processes of patients with MM, and can lead to renal impairment. Scientists point out that BJP have peptidolytic and nucleolytic activity, which can lead porcine kidney proximal tubule (LLC-PK1) to apoptosis in vitro experiments. By treating the cytotoxic BJP with serine protease inhibitor (DFP), BJP lost not only their catalytic activity, but also the cytotoxic effects. Therefore, further research on BJP will helpful to understand the pathogenesis of renal impairment in MM patients and may provide a new idea and measure for the treatment of MM with renal impairment. This article reviews the basic research and progress on the catalytic activity of BJP.

Objective:To investigate the m echanism of D- amino acid oxidase/D- Alanine system in killing K5 6 2 e cells in vitro.Methods:The killing effects of D- Ala on K5 6 2 e cells stably expressing DAAO and GFP were observed.H2 O2 production by DAAO+ cells were m easured by the phenol red oxidation assay.L owry method was used to determ ine the protein quantities of cells and fluorescent intensities of GFP+ cells were assayed by flow cytom eter.Results:KDf Gd cells were killed completely after treated with 2 5 mm ol/L D- Ala for 2 4 h.The effect of D - Ala at 2 0 m mol/L on KDf Gd cells increased apparently within 4 8h,but the same effect was not observed if D - Ala was below 15 m mol/L .The cytotoxicity of D- Ala in KDf Gd cells was more sensitive than in parental K 5 6 2 e cells.The H2 O2 levels in the medium were consistent with the killing effects of D- Ala.Conclusion:The killing effects of DAAO/D- Ala system is m ediated by H2 O2 .

Hypereosinophilic syndromes (HES) are a heterogeneous group of uncommon disorders which characterized by marked peripheral eosinophilia and function damage of target organ, with different etiologies, mechanisms and therapies in different subtypes. Formerly the prognosis was very poor, nowadays with great development in science and medicine, we can understand HES much better in classification, diagnosis and therapy, including the development of novel targeted therapies, such as tyrosine kinase inhibitors and humanized monoclonal antibodies, which increased the treatment selection and complexity of therapeutic decisions in HES. This review discusses the classification of HES and characters of different subtypes, including therapeutic methods, which can help clinical doctors to have a good understanding of HES.

Renal damage is one of the most common complications and cause of death in patients with multiple myeloma (MM). The studies have pointed out that early renal impairment is risk factor for progress of this disease, timely diagnosis and prompt intervention therapy are very important to improve the prognosis and survival of MM patients. Therefore, the diagnosis of early renal damage is crucial for clinical treatment. The progress on detection of early renal damage parameters and their value are reviewed in this article.

The 8p11 myeloproliferative syndrome (EMS) is named as stem cell leukemia/lymphoma syndrome, and is an aggressive neoplasm associated with chromosomal translocations involving the fibroblast growth factor receptor 1 (FGFR1) tyrosine kinase gene on chromosome 8p11-12. EMS is a syndrome characterized by peripheral blood leucocytosis with eosinophilia, myeloid hyperplasia of bone marrow, and T-cell lymphoblastic leukemia/lymphoma. Clinically, EMS is an aggressive disease with a short chronic phase before rapid transformation into acute leukemia. Its prognosis is poor. The only curative option for patients with EMS at this time appears to be bone marrow or stem cell transplantation. At the molecular level, all cases carry a chromosomal abnormality involving the FGFR1 gene at chromosome 8p11. The novel chimeric proteins foster dimerization and ligand-independent activation of FGFR1 tyrosine kinase, subsequently promoting activation of downstream pathways involved in proliferation and malignant transformation of cells. Currently, 13 translocations and 1 insertion have been identified. Here, the current review mainly focuses on molecular genetic features, pathogenic mechanisms and therapy of EMS.

This study was aimed to investigate the clinical characteristics and treatment of patients with autoimmune disease combined with non-Hodgkin lymphoma (NHL). The clinical characteristics and pathologic patterns of 6 patients with NHL who concurrently suffered from autoimmune diseases were analysed retrospectively from aspects of clinical course, pathologic features, and therapy. Treatment outcomes for autoimmune diseases and NHL were observed. The results showed that 6 patients included 4 females and 2 males, range in age from 28 to 65 years with a median age of 56 years. The autoimmune diseases are Sjogren's syndrome (SS, 2 cases), rheumatoid arthritis (RA, 2 cases), ulcerative colitis (UC, 1 case) and Crohn's disease (CD, 1 case). The NHL diseases located not only in the lymph node (n = 3) but also in extranodal sites (n = 3). Histologically, 3 cases were diffuse large B cell lymphoma (DLBCL), 2 cases were extranodal nasal NK/T lymphoma (ENKL) and 1 case was peripheral T cell lymphoma, not otherwise specified. Based on CD10, Bcl-6 and MUM1 expression patterns, all 3 DLBCL were classified as non-GC subtype. EBER positive tumor cells were detected in 2 case of ENKL. 5 patients achieved a complete remission (83%) and 1 patient was primary drug-resistant after CHOP chemotherapy or involved radiotherapy. Median survival from the time of lymphoma diagnosis was 3 years. 1 patient showed clinical improvement of the SS symptoms, 2 patients (CD and UC) showed stable state of disease and 2 patients with RA and 1 patient with SS needed continuing treatment for their autoimmune diseases after chemotherapy for NHL. It is concluded that the development of NHL is one of the most serious complications in patients with autoimmune diseases. There is an increased frequency of non-GC subtype DLBCL. CHOP combined with or without radiotherapy proves to be effective for autoimmune disease patients with aggressive NHL but ineffective for concurrent autoimmune diseases.
