After signs of risk have been happened in risk management of medical equipment at present, reports are taken step by step. So there is a report not timely, incomplete information, it is difficult to monitor, and many other problems. With the improvement of risk management requirements; the development of the information technology s apply, and increasing sources of information used for risk early warning analysis. This paper analyzes the requirement of risk management, and proposes a total solution of enterprise risk early warning based on EAI. It will make managers accurately and fully grasp the risks, find risk signs timely, speed up the response to risk.

In vitro differentiation of bone marrow stromal stem cells (BMSCs) into neural cells has been a hot study in neuroscience. Presently, under some experimental conditions, tissue-specific stem cells have been shown to give rise to cell lineages not normally found in the organ or tissue of residence. BMSCs have been reported to generate skeletal cells, gastric cardiac cells, oval hepatocytes, as well as glia and neuron-like cells. Cells from postnatal bone marrow were induced to proliferate and differentiate into gila and neurons. The present study explored the characteristics of its transformation.

BACKGROUND:In recent years, the use of chimeric antigen receptor modified T cells (CAR-T cells) has achieved good results in the treatment of hematological malignancies. OBJECTIVE:To summarize the CAR-T technology, and its anti-tumor mechamism, progress in the treatment of hematological malignancies as well as its safety and coping strategies. METHODS:A search of PubMed, CNKI, Wanfang by computer was performed for articles related to CAR-T published from January 2010 to January 2016, using the keywords of CAR-T in English and Chinese, respectively. RESULTS AND CONCLUSION:The main principles that CAR-T cells fight against tumors are as follows: (1) resistance to immune escape through down-regulation of MHC; (2) production of interleukin-6, -10 indirectly influences the growth of tumor cells; and (3) tumor microenvironment changes inhibit tumor growth. The use of CAR-T in the treatment of hematological malignancies has been developed by leaps and bounds in recent years. Current studies concerning B cell lymphoma mainly focus on anti-CD19 CAR-T cells that have certain therapeutic effects on acute myeloid leukemia and acute lymphoblastic leukemia. However, its safety and effectiveness have yet to be studied.

Monoclonal gammopathy of undetermined significances (MGUS) is a premalignant clonal disorder occurring in 4.2 ％ of adults ＞50 years old,and is associated with a 1％ risk every year of progression to multiple myeloma (MM),light-chain amyloidosis and related conditions.Differential diagnosis of asymptomatic and symptomatic monoclonal gammopathies is the determinant for starting therapy.Most patients with MGUS need frequent assessment and follow-up.A few patients with MGUS might progress into smoldering MM and symptomatic MM,or develop into light chain diseases such as AL amyloidosis and light chain deposition disease caused by M-protein,who should be followed with effective therapy.The above were in detail reviewed in the 54th American Society of Hematology (ASH) annual meetina.

Objective To construct the human Alzheimer's disease (AD) specific single chain anti‐bodies (scFv) library for sceening human AD scFv to Aβ1‐42 oligomers .Methods RNA was isola‐ted from 40 ml peripheral blood taken from 18 AD patients .Variable heavy (V H ) and variable light (VL ) genes were amplified by RT‐PCR and linked to the scFv fragments that were then cloned into the phage vector pCANTAB5E .The scFv library was constructed by electroporating E .coli TG1 cells into the pCANTAB5E and rescuing the assistant phage M13K07 .Results The total RNA was extracted .The VH and VL genes were amplified .Electropharesis showed that the length of VH and VL genes was 360bp and 300bp respectively and the length of linked scFv was 750bp .The 2 .4 × 109 scFv library was thus constructed and identified by BstN I digestion .Elec‐tropharesis showed that the length of BstN I‐digested scFv fragments varied ,indicating that the library is of a good diversity .Conclusion The human AD phage scFv library we constructed lays a foundation for screening the antibodies to Aβ1‐42 oligomers and the treatment of AD .

BACKGROUND:In recent years, with the development of China Marrow Donor Program and the improvement of human leukocyte antigen (HLA) typing technique, novel aleles of human leukocyte antigen have been discovered constantly in China. OBJECTIVE:To identify and confirm a novel HLA alele in a Chinese individual. METHODS: A new HLA alele was found during routine human leukocyte antigen genotyping by PCR-sequence specific oligonucleotide probes and sequencing-based typing. RESULTS AND CONCLUSION:The HLA-B locus hybridization probe reaction patterns of this sample did not match with any known HLA-B aleles or alelic combinations. Exons 2, 3 were sequenced in both directions using HLA-B sequence primer and group-specific sequencing primer. The obtained sequence had 2nts change from B*07:02:01 at nt 226 and nt 228 where A->G (codon 76 ATA->GTG) and resulting in a coding change, 76 isoleucine (I) was changed to valine (V). This nucleotide sequence has been submitted to the GenBank nucleotide sequence database and it is available under the accession number HM989017. A novel HLA alele, HLA-B*07:110, was identified, and was named officialy by the WHO Nomenclature Committee.

Objective:To explore the counselor verbal response modes of psychic hot-line counseling and its characteristics.Methods:Through a qualitative study with category analysis method,8 pieces of audio recordings were collected,in each of which the entire duration was between 30 minutes to 50 minutes.And all of these record-ings were transcribed word by word.Meaningful 1202 pieces were deeply analyzed.Results:There were 5 core counselor verbal response types in hot-line counseling,greeting response,set-up response,listening response,follow-up response,and affecting response,all of which had 24 concept categories.All of the online counselors used the 5 types of verbal response.The listening response and follow-up response were the highest frequent types.Greeting response and set-up response were used mostly in the initial stage of counseling.Listening response,and follow-up response were used mostly in the stage of describing problem.Affecting response was sharply increased in the stage of analyzing problem.Greeting response and set-up response were used mostly in last stage of counseling.Conclu-sion:It suggests that there are 5 core counselor verbal response types and 24 concept categories in hot-line counse-ling.The listening response and follow-up response are the highest frequent types.Different types of verbal re-sponse modes used by counselor in different stages due to different intention.

Objective To explore the value of T wave alternans (TWA) in prediction ventricular arrhythmias in post-op TOF children. Methods The characteristics of TWA were retrospectively analyzed in 36 post-op TOF patients and 120 age-matched normal children. The relationship of sustained TWA and ventricular arrhythmias was also analysed. Results Compared with normal children, the incidence of sustained TWA was significantly increased in post-op TOF group (χ2=6.98, P<0.05). In post-op TOF patients, the incidence of ventricular arrhythmia was much higher when sustained TWA was present (χ2=10.41, P<0.05). Conclusions There exists electrophysiological basis for ventricular arrhythmia in post-op TOF children. Sustained TWA has important value in prediction of ventricular arrhythmia of post-op TOF.
