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.

Objective By constructing mortalin stably expressing ovarian cancer cell lines in A 2780 and A2780/cis, we demonstrate the role of mortalin in the ovarian cancer cell growth .Methods CCK-8 assay was used to measure cell viability in the overexpression mortalin group compared with the control group .The flow cytometry analysis was used to understand the effect of upregulated mortalin on the ovarian cancer cell cycle .Western blotting was used to determine the expression and phosphorylation level of MAPK /ERK and JNK/SAPK signal pathways .Results The results showed that increased expression of mortalin could accelerate ovarian cancer cell proliferation and promote G 1 transition, leading to a faster restoration of normal distribution of cell cycle .We found that mortalin overexpression significantly activated p-Raf and p-ERK1/2, but not p-JNK.Conclusion The results demonstrate that mortalin effect on the ovarian cancer cell proliferation contributes to active the MAPK-ERK signaling pathway .

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.

Objective To compare the mid-term results of video-assisted pulmonary veins isolation and box-lesion for lone atrial fibrillation.Methods Between June 2010 to November 2012,80 lone atrial fibrillation(LAF) patients underwent minimally invasive surgical ablation in Beijing Anzhen Hospital,and all of them received left atrial appendage excision and Marshall ligament break in the surgery.Among them,37 cases were performed two epicardial ablation lines in order to created box-lesion based on PVI(14 paroxysmal AF and 23 persistent AF).Follow-up was finished after discharge.Results Mean follow-up was(18.8 ± 7.4) months,and 2 patients were died with non-cardiac disease.The success rate is 78.8％ (Paroxysmal AF 87.9％;Persistent AF 72.3％).In the paroxysmal AF patients,the success rate for PVI and Box lesion treatment was 84.6％ (11/13) and 92.9％ (13/14),P =0.45;in the persistent AF patients,the success rate for PVI and Box-lesion was 58.3％ (14/24) and 87.5％ (14/16),P =0.04.Conclusion Addition of epicedial ablation lines might increase the cure rate for lone AF therapy,especially for persistent AF.

Objective:To investigate the effect of paraformaldehyde fixation on measuring the protein-protein interaction by fluorescence resonance energy transfer(FRET)to resolve the problem of FRET efficiency calculation in excess-movement cells.Methods:The C terminals of TCR ? chain(TRA)and TCR ? chain(TRB)genes,which were ideal for protein-protein interaction research,were fused with ECFP and EYFP gene respectively by fusion PCR and transferred into target cell.A grou Pcells were fixed in paraformaldehyde(0.5%)for 0.5~1h and another left alive,then these cells were subject to ECFP/EYFP FRET calculation with confocal laser scanning microscope.The ECFP/EYFP FRET efficiencies in live and fixed cell were analyzed and compared.Results:There is no significant statistical difference between the ECFP/EYFP FRET efficiencies of live cell and cell fixed with lower paraformaldehyde concentration and shorter incubation time.Conclusion:fixation with low-concentration paraformaldehyde and short-time incubation has no distinct influence on measuring protein-protein interaction,and facilitated the FRET calculation in excess-movement cells.

Objective To analyze the clinical features,treatment and prognosis of the pancreatoblastoma (PB).Methods A total of 9 patients including 4 boys and 5 girls diagnosed as pancreatoblastoma in Beijing Tongren Hospital Affiliated to Capital Medical University between July 2008 and February 2016 were enrolled.The clinical features,therapy and prognosis were analyzed.Results (1) Clinical manifestations:6 cases had abdominal mass,1 case had jaundice,2 cases had abdominal pain at the time of diagnosis;5 cases were found in caput pancreatis,2 cases were found in corpora pancreatis and 2 cases were found in cauda pancreatis;4 cases had local tumor,3 cases had local invasion,and 2 cases had liver metastasis at diagnosis.(2) Enzymology and tumor marks:elevated alpha-fetoprotein (AFP) was found in 5 cases (48.5-52 971.0 μg/L),elevated neuron-specific enolase(NSE) was found in 5 cases(22.4-53.4 pg/L),elevated carbohydrate antigen 125 (CA-125) was found in 5 cases [(40.3-122.8) × 103 U/ L],elevated carbohydrate antigen 19-9 (CA19-9) was found in 2 cases [(65.4-362.5) × 103 U/ L],elevated lactate dehydrogenase was found in 2 cases(380 ～ 838 U/L) and elevated hemodiastase was found in 2 cases (105.5-122.8 U/L).(3) Treatment and prognosis:in 9 patients,the tumors were resected at first in 6 patients,and 5 of them remitted until now,1 of them relapsed after the comprehensive treatment for 9 months.Two of the patients underwent operation after the chemotherapy,in which 1 case received complete resection but without chemotherapy after the surgery,whom relapsed 1 year later;and the other one was resected partly.But after stopping the comprehensive treatment for 6 months,the disease relapsed.One patient could not receive operate because of huge tumor size,and the chemotherapy failed to control tumor progression;the patient died without operation.Three relapsed children were still in chemotherapy.The median follow-up period was 21 months (8-98 months).Conclusions AFP may be used as monitoring indicator for PB.Complete tumor resection is an important factor affecting the outcome.Adjuvant chemotherapy may reduce recurrence and prolong survival.
