Platelet additive solutions (PAS) can partly or fully substitute blood plasma during platelet storage in normal air temperature. There are some advantages such as avoiding transfusion of large volume of plasma with possible adverse reactions and circulatory overload, saving plasma for other purposes, improving storage conditions, maintaining the viability and haemostatic function of platelet at normal level, and making it easy to inactivate pathogens. There has been an increasing interest in the study of PAS in the past 20 years, the compositions of different PAS have been reported one after another, and the protective effects of PAS on platelets have become better and better. This article focuses on the advances of studies of the composition of PAS, the functions of the different compositions and platelet quality in vitro and in vivo after storage.

Objective To investigate the clinical characteristics,treatment and prognosis of hepatoblastoma (HB) patients with the central nervous system (CNS) metastasis.Methods The clinical data of 12 patients with CNS metastasis who were admitted to Beijing Tongren Hospital,Capital Medical University from January 2011 to June 2016 were retrospectively analyzed.The clinical features,treatment and prognosis of HB patients with CNS metastasis were summarized.Results (1) Clinical features:all 12 patients were diagnosed as stage-Ⅳ patients according to postoperative Children's Oncology Group (COG) stage system.The primary positions of extrahepatic metastatic characteristics were as follows:lung metastasis in 12 cases,bone metastasis in 3 cases,and adrenal metastasis in 2 cases,right atrial metastasis in 1 case,and abdominal lymph node metastasis in 1 case.Fetal and epithelial mixed type was the most common type in pathologic Pathologic classification of HB (50％,6/12 cases).CNS metastasis was detected in all 12 cases during the course of treatment.Brain metastasis were found in 11 cases of CNS imaging features,and 1 case had spinal metastatic tumors.(2) The treatment for CNS metastasis:all cases were given chemotherapy-based comprehensive treatment after being diagnosed as CNS metastasis of HB.Ten cases of CNS metastasis were treated by maintenance chemotherapy and 2 cases received chemotherapy plus intracranial tumor resection.(3) The prognosis of HB with CNS metastasis:the follow-up time was from 7 months to 54 months in 12 HB cases with CNS metastasis,and the median follow-up time was 20 months.The survival time of HB was 1-15 months,and the median survival time was 3.5 months after the diagnosis of CNS metastasis.Two cases of CNS metastasis were given intracranial tumor resection and chemotherapy and were followed up to June 2016,and survival time was 15 months and 5 months respectively.The survival time of other 10 cases without intracranial surgery was 1-6 months,and the median survival time was 3 months.By drawing survival function curve and applying Log-Rank test for CNS transfer children,the survival time of patients given intracranial tumor resection and chemotherapy was longer than those without surgery (P ＜ 0.05).Conclusions The occurrence of CNS metastasis occurred in HB patients in phase-Ⅳ patients with pulmonary metastasis.The most common site of CNS metastasis is brain metastasis,which is hematogenous metastatic pathway,and 1 case of spinal cord metastasis was considered as the local invasion and metastasis.For HB cases with CNS metastasis,the survival time is short and the prognosis is poor,but the survival time might be prolonged for the phase-Ⅳ patients with intracranial tumor resection.

Background and purpose: Natural killer/T cell lymphoma in poor effects, the production of multidrug resistance is one of the reasons to reduce the chemotherapy effect or failure. This study aimed to discuss the multidrug resistance associated protein 4 (ABCC4/MRP4) gene and multidrug resistance associated protein 5 (ABCC5/MRP5) gene expression in NK/T cell lymphoma SNK-6, YTS cell lines and NK/T cell lymphoma tissues, and the relationship between the level of ABCC4/MRP4, ABCC5/MRP5 gene expression and the clinical efifcacy. Methods:Real-time lfuorescence quantitative PCR (Real time-PCR) and immunohistochemical method (IHC) were used to detect the ABCC4/MRP4, ABCC5/MRP5 gene and protein expression. Results:Compared with the normal NK cells, ABCC4/MRP4 and ABCC5/MRP5 gene in SNK-6, YTS cell lines were highly expressed (P<0.05); Compared with rhinitis tissues, the expression of ABCC4/MRP4, ABCC5/MRP5 gene was higher in the NK/T cell lymphoma tissues (P<0.05);The expression level of ABCC4/MRP4 and ABCC5/MRP5 gene was negative correlation with clinical efifcacy (P<0.05). Conclusion: The expression of ABCC4/MRP4 and ABCC5/MRP5 gene affects the of clinical efifcacy of NK/T cell lymphoma.

This study is to explore new lead compounds by inhibition of Pin1 for anticancer therapy using temperature sensitive mutants. As Pin1 is conserved from yeast to human, we established a high-throughput screening method for Pin1 inhibitors, which employed yeast assay. This method led to the identification of one potent hits, 8-11. In vitro, 8-11 inhibited purified Pin1 enzyme activity with IC50 of (10.40 +/- 1.68) micromol x L(-1), induced G1 phase arrest and apoptosis, showed inhibitory effects on a series of cancer cell proliferation, reduced Cyclin D1 expression, was defined as reciprocally matched for protein-ligand complex in virtual docking analysis and reduced cell migration ability. In vivo, we could observe reduction of tumor volume after treatment with 8-11 in xenograft mice compared with vehicle DMSO treatment. Altogether, these results provide for the first time the involvement of 8-11 in the anticancer activity against Pin1.

OBJECTIVETo investigate cell apoptosis, mitochondrial membrane potential, cytochrome C and mechanisms of mitochondria in lymphocyte apoptosis of sepsis.

METHODSIn the research, female C57BL/6 mice whose body weight ranged from 17 to 25 grams were utilized and assigned randomly to two groups: sham operated group (Control), cecal ligation and puncture group (CLP). The present study was undertaken by using the mice splenic lymphocyte to investigate cell apoptosis, mitochondrial membrane potential, cytochrome C. The apoptosis alteration was evaluated by Annexin V-FITC/PI double staining with flow cytometry. The alteration of mitochondrial membrane potential was investigated by Rhodamine-123 staining of cells. Cytochrome C of mitochondria and cytosol was investigated by Western blot methods. Statistical analysis was performed using SPSS 11.5 for Windows software. Experiment data was indicated with mean ± standard.

RESULTSThe splenic lymphocyte apoptosis was significantly accelerated in the CLP group when compared with that in control group (17.3% ± 2.2% vs. 3.5% ± 0.5%, P < 0.05). The Rhodamine-123 fluorescent intensity in splenic lymphocyte apoptosis was reduced in CLP group (76.2% ± 1.6%). Comparison between sham group (99.6% ± 0.4%) and CLP group had statistical significance (P < 0.05). Apoptosis could induce mitochondrial cytochrome C release into cytoplasm. In the CLP group, elevation of cytochrome C in cytosol was concurrently in accordance with decline in mitochondrial cytochrome C content.

CONCLUSIONThese data suggest that mitochondria and mitochondria signal pathway play an important role in lymphocyte apoptosis of sepsis.
