Objective: To investigate the anticancer activity of Luteolin (Lu) and its synergism effect with bacillus calmette-guerin (BCG) on human bladder cancer cell line BIU-87. Methods: Cultured BIU-87 cells were treated with different concentrations of Lu alone or the combination of Lu with BCG. MTT assay was used to measure the cell proliferation inhibition, and IC50 was calculated. Cell cycle and apoptosis were analyzed by lfow cytometry with propidiumiodide (PI) staining and Annexin-V FITC/PI dual parameter markers to clarify the mechanism of inhibiting cell proliferation and inducing apoptosis. Caspase-3 and phosphorylated c-Jun N-terminal kinases (P-JNK) expression were measured to detect the apoptosis signal pathways of Lu in cancer cells. Results: Both Lu and BCG apparently inhibited the cell proliferation and induced the apoptosis dose-dependently, and microscope observation showed morphological changes in the apoptosis. Flow cytometry indicated that Lu arrested the cell cycle at G2 phase (P<0.05). It sensitized BCG-induced cytotoxicity and cell apoptosis, and upregulated expression of caspase-3 and activation of JNK (P<0.05). Conclusion: As an effective anticancer agent, Lu can sensitize the effect of BCG by inducing the cell cycle arrest and apoptosis. hTis synergism effect is achieved by activation of caspase-3 and JNK. Combination of Lu with BCG may be one of the potential treatment for bladder cancer.

Objective To investigate the correct diagnosis and treatment of myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene. Methods A case of patient who was diagnosed as myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene was reported, and the literature was reviewed. Results The patient was diagnosed as typical T-lymphoblast lymphoma (T-LBL) by the lymph node pathologic diagnosis, while the diagnosis of myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene was made correctly by the whole examination and analysis. The patient acquired deep complete remission quickly after taking the low dose of imatinib. Conclusions Myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene are a rare hematologic tumor. Though pathological diagnosis is the golden standard for lymphoma, sometimes the other factors should be taken into consideration and make an overall analysis of clinical picture and a correct view of the pathological diagnosis, which could avoid the misdiagnosis and improper treatment.

We prepared the isosorbide-5-mononitrate pulsatile controlled-release pellets (PCRP) and studied the influencing factors in vitro. The isosorbide-5-mononitrate (5-ISMN) pellets prepared by extrusion-spheronization technology were coated with swelling material as the inner coating swelling layer, and with ethylcellulose aqueous dispersion as the outer coating controlled layer. The influences of the coating materials of the swelling layer, the coating levels of the swelling layer and controlled layer,and the pH values of the media on the release of 5-ISMN from PCRP were investigated. The drug release from the pellets was pulsatile. The ISMN-5-PCRP, with a lag time of 5 h and more than 80% released within the following 1.5 h,were prepared by using the low-substituted hydroxypropyl cellulose as the inner swelling layer with 15% (weight) in coating thickness, and the ethylcellulose aqueous dispersion as the outer controlling layer with 13% (weight) in coating thickness.

Objective To summarize the common complications of chronic lymphocytic leukemia (CLL). Methods 203 cases of CLL patients from the Institute of Hematology and Blood Diseases Hospital, CAMS & PUMC, were retrospectively reviewed and followed up.The common complications of CLL were also summarized. Survival analysis was used to analyze the prognostic value of these common complications. Results 40 (19.7 %) patients sustained infectious complications,and the respiratory tract infections were the most common type (75.6 %). 15 (7.4 %) patients complicated with autoimmune diseases (AID), and the autoimmune hemolytic anemia(AIHA) were the most common type(31.3%). 8(3.94 %) patients suffered from secondary cancers, including lung cancer, etc.3(1.48 %) patients developed other high-grade lymphomas, 2 of them transformed to prolymphocytic leukemia (PLL), 1 of them transformed to diffuse large B cell lymphoma (DLBCL) which was called Richter syndrome. Complicating infections and secondary cancers or transformations were associated with poor prognosis.Complicating AIDs was not an adverse prognostic factor. Conclusion Infections, AIDs and secondary cancers or transformations are common complications of CLL patients.Lung is the most common infectious site, and AIHA is the most common AID type,none secondary cancer s incidence rate is specifically higher than the others. Infections and secondary cancers or transformations indicate poor prognosis.
