Objective To evaluate if the assay of platelet-associated immunoglobulin G (PAIgG) can improve the sensitivity of monoclonal antibody immobilization of platelet antigens assay (MAIPA) in immune thrombocytopenic purpura (ITP).Methods Anti-GP Ⅱb/Ⅲa and anti-GP Ⅰb/Ⅸ autoantibodies were detected by a modified MAIPA;PAIgG was detected by competitive ELISA.MAIPA and PAIgG were done simultaneously in 190 patients with thrombocytopenia,in which 132 were diagnosed as ITP according to the diagnostic criteria Kappa test was used to analyze the concordance between MAIPA and PAIgG.Results The sensitivities of PAIgG alone or in parallel with MAIPA to ITP were 32.6% and 37.2% higher than MAIPA alone respectively,while their specifieities were 51.7% and 56.9% lower respectively.The sensitivity,specificity,positive predictive value,negative predictive value of PAIgG in series with MAIPA were all not superior to MAIPA alone.The kappa values between MAIPA and PAIgG in ITP and non-immune thrombocytopenia were 0.129 and 0.012 respectively,which meant the concordance between them was poor.Conclusion The detection of PAIgG should not be used as screening before MAIPA in distinguishing immune from non-immune thrombocytopenia.

Objective:To study the detection value of platelet activation indexes and platelet parameters in patients with hepatitis B-induced cirrhosis.Methods:40 patients with hepatitis B-induced cirrhosis in our hospital from November 2015 to August 2016 were selected as the observation group.40 healthy subjects went through physical examination during the same period were chosen as the control group.The platelet activation indexes and platelet parameters of subjects with same age in two groups were detected and compared.The detection results of the two items in patients with different stages of hepatitis B-induced cirrhosis were compared,too.Results:The PLT of observation group was lower than that of control group,while the other platelet parameters and platelet activation indexes were all higher than those of control group.The detection results of two items in patients with different stages of hepatitis B-induced cirrhosis were with significant differences,all P＜0.05.Conclusion:The platelet activation indexes and platelet parameters in patients with hepatitis B-induced cirrhosis are obviously abnormally expressed.There are significant differences among the detection results in patients with different stages.Therefore,surveillance of those indexes in patients with hepatitis B-induced cirrhosis should be strengthened.

Objective To explore establishment of indicator system to evaluate basic capacities of trainers of training for community general practitioners (GPs) to standardize their capacity building and management.Methods Questionnaire survey was conducted among 190 trainers of training for community health managers and GPs who were involved in community health-care and health-care service management in 12 districts of Shanghai to investigate what basic capacities the trainers should have.Delphi expert consultation method was used to construct an evaluation indicator system.Firstly, an evaluation form was formulated based on the preceding questionnaire.Then, two rounds of expert consultation were carried out with 28 experts specialized in general practice, training for GPs, public health and health management.The last step was to set up an evaluation indicator system based on experts' opinions with statistical analysis.Results The newly-established system consisted of five first-grade indicators including comprehensive performance, capacities and personal willingness, background of education and career, personal potential for professional development, capacity in general practice and capacity in training for GPs, and 57 second-grade indicators.Activity coefficient of the experts was all 100%, authority coefficients of the experts were 0.85,and harmonious coefficient of importance of the evaluation was 0.190 and 0.225 ( all P ＜ 0.01 ),respectively, in two rounds of Delphi consultation.Conclusions The preliminarily established indicator system to evaluate capacities of trainers of training for community GPs in diverse aspects can be used as reference for quality critria in selection of trainers of training for community GPs.

Baculovirus DNA polymerase gene belongs to an early gene of baculovirus. It is a necessary gene required for replication of virus in insect cells. It can encode DNA polymerase induced by virus. In the process of replication, DNA polymerase can bind to homologous regions and non-homologous regions, which are believed to act as the origins of virus DNA replication with other replication factors. In addition, DNA polymerase has advantages over occlusion protein and egt gene for resolving deep branching taxonomic relationships of baculovirus phylogenies.

0.05) in incidence rate for bone marrow suppression,gastrointestinal reaction,hepatic damage and mucosa damage and infection between different therapic courses.Central nervous system leukemia(CNSL) occured in one high risk case followed up at 12 month after complete remission(CR);the incidence rate was 12.5%.Conclusions HD-MTX is practicable in basic-level hospitals,as long as there are perfect preparation,fitness hydration and alkalization and leucovorin rescue being used in time.

N-acetyl-L-cysteine (NAC) capped quantum dots (QDs) were synthesized by a hydrothermal method and coated with 2-amino-2-deoxy-D-glucose (DG), polyethylene glycol (PEG), and 9-D-arginine (9R). The optical properties, morphology and structure of 9R/DG-coated CdTe QDs were characterized by ultraviolet-visible spectrometry, fluorescence spectrum, Fourier transform infrared (FTIR), proton nuclear magnetic resonance (1H NMR), liquid chromatography-mass spectrometer (LC-MS), sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and transmission electron micrographs (TEM). Furthermore, the biocompatibility, tumor targeted ability and transmembrane action of 9R/DG-coated CdTe QDs were studied. Results indicated that 9R/DG-coated CdTe QDs was constructed successfully by ligand exchange. The 9R/DG-coated CdTe QDs with the size of 8-10 nm had good dispersity and the absorbance and fluorescence peaks of CdTe QDs after modification were red shifted from 480 nm to 510 nm and 627 nm to 659 nm, respectively. In addition, the CdTe QDs modified by PEG, DG and 9R displayed good biocompatibility, high targeted ability to the cancer cells with glucose transporter type 1 (GLUT1) receptor high expression and obvious transmembrane ability.
