2.Progress in inflammatory cardiomyopathy
International Journal of Pediatrics 2011;38(2):141-143
Viral myocarditis can cause severe myocardial injury and even acute heart failure, then evolve into dilated cardiomyopathy, known as inflammatory cardiomyopathy. Immune reaction plays a key role in the transformation from viral myocarditis into dilated cardiomyopathy, including virus RNA continuous replication,immune-mediated injury, cellular apoptosis, other cellular immune response , myocardial antibodies and other humoral immune response. In the clinical treatment, besides anti-heart failure and cardiac nutrition, the use of ribavirin, α1-receptor blockers, β-receptor blockers, calcium channel blockers, angiotensin converting enzyme inhibitors and spironolactone should be emphasized.

Herald of Medicine 2017;36(8):843-846
With the development of clinical pharmacy in hospital,the demand for pharmacy intravenous admixture services (PIVAS) has been gradually increased.By being built inside the pharmacies,PIVAS of this hospital has created a full range of integrated pharmacy service platform.With independent research and development of information management system,innovative design of the modules and equipments based on the concept of internet of things,and integration of artificial and computerized checking,PIVAS of this hospital has formed a system of prevention and control chain,it has been deepening the connotation of clinical pharmacy services,and providing higher quality pharmacy services to clinical drug using.
4.Learning needs of nursing students for nursing English in senior high vocational school
Chinese Journal of Medical Education Research 2013;(1):99-102
Objective To understand the learning needs of nursing students for nursing English in senior high vocational school.Methods A survey was carried out among 982 three-year nursing students in grade 2007-2009 in Cangzhou medical college by questionnaire.The data collected were analyzed using descriptive statistics with SPSS 17.0.Results Most students (93.0%) believed that nursing English was important and had a strong desire for most English skills,especially speaking and listening ability.They (90.7%) expected nursing teachers to take charge of or participate in teaching work and some students (30.6%) were dissatisfied with teaching material.They depended on teachers' instruction and preferred learning in real situations.Conclusions Nursing students in senior high vocational school have strong needs for nursing English,but there is a gap between current teaching situation and learning needs,which the course designers and teachers should take into full consideration in order to make the teaching more effective.
5.Comparative analysis of retrieval results from PubMed and Embase.com
Chinese Journal of Medical Library and Information Science 2014;(9):75-77
Objective To recommend the appropriate retrieval tools for scientific researchers and improve their re-trieval efficiency by comparatively analyzing the retrieval results from PubMed and Embase .com.Methods Eight retrieval terms from different subjects were used to retrieve PubMed and Embase .com by subject headings and basic retrieval methods than can automatically transfer their function .Results Six different results were retrieved from PubMed and Embase.com with 8 retrieval terms.Conclusion The recall ratio is higher in Embase.com than in PubMed when they are retrieved by subject headings while the accuracy ratio is higher in PubMed than in Embase . com when they are retrieved by basic retrieval methods than can automatically transfer their function although error transformation occurs in both PubMed and Embase.com.
6.Current situation of reference service in library and its problems to which attention should be paid
Chinese Journal of Medical Library and Information Science 2015;(6):59-61
Reference service is one of the key tasks in library.The current situation of reference service in library and its problems were analyzed from the need of readers, and the problems to which attention should be paid were pointed out from its convenience and time-effectiveness .
8.Construction of pEGFP-N1-TGF-β1 recombinant plasmid and transfected it into primary cultured AEC-Ⅱ of neonatal piglet using lipofectamine 2000
Chinese Journal of Emergency Medicine 2016;25(1):50-56
Objective To construct pEGFP-N1-TGF-β1 recombinant plasmid and transfect it into primary cultured neonatal piglet type Ⅱ alveolar epithelium cell (AEC-Ⅱ) by using lipofectamine 2000,in order to provide basis of methodology for producing recombinant plasmids for transplantation of transfected AEC-Ⅱ into ALI/ARDS animal model lungs.Methods PCR primers were designed to amplify the human TGF-β1 cDNA fragment from plasmid.XhoI and EcoRI were used for double digesting the empty plasmid pEGFP-N1 and cDNA fragment of human TGF-β1.Then the products of double enzyme digestion by using T4 DNA ligase were connected and transformed into DH5α and cultured over night for 16 hours.The structure of recombinant plasmid was identified by using PCR and base sequencing to verify the correctness of pEGFP-N1-TGF-β1 recombinant plasmid.It was then transfected into primarily cultured AEC-Ⅱ by lipofectamine2000 mediated transfection and cultured for another 48 hour.Plasmid DNA (pEGFP-N1-TGF-β1 recombinant plasmid) and lipofectamine 2000 were added into serum-free DMEM respectively,then DNA suspension and Lipofectamine 2000 suspension were blended together and added into cells.After 24-48 hours later,the expression level of enhanced green fluorescent protein (EGFP) was evaluated under fluorescence microscope.Results The structure of vector was verified as pEGFP-N1-TGF-β1 recombinant plasmid by using PCR and base sequencing.Green fluorescence found in some cells showed that the pEGFP-N1-TGF-β1 recombinant plasmids had been successfully transfected into primary cultured AEC-Ⅱ,however,the transfection efficiency still need tobe further improved such as repeating the transfection procedure once again or using adenovirus mediated transfection method to improve the efficiceny and to transplant the cells into animal lungs eventually.Conclusions pEGFP-N1-TGF-β1 recombinant plasmid was successfully constructed and,for the first time,transfected into primarily cultured AEC-Ⅱ of newborn piglets.This established method should be useful for investigation of therapeutic effect and outcomes of lung with experimental acute lung injury.
9.THE RESEARCH ON THE PROLIFERATION AND DIFFERENTIATION OF MOUSE PRIMORDIAL GERM CELLS IN VITRO
Acta Anatomica Sinica 1955;0(03):-
Objective To research on the proliferation and differentiation in vitro of primordial germ cells. Methods We got plenty of primordial germ cells(PGCs) by co-culture of PGCs with sertoli cells(SCs).The primary cells formed embryoid bodies(EBs) by suspension culture.furthermore,these EBs were plated on gelatin-coated culture plates for spontaneous differentiation. Results We got plenty of PGCs by coculture.Primary PGCs and passaged PGCs for histochemistry staining with AKP and immunohistochemistry staining for SSEA-1 display positive character.The EBs by suspension culture differentiated into epithelial-like,fibroblast-like and neuronal-like cells in vitro. Conclusion Primordial germ cells can proliferate and keep the character of stem cells by co-culture with SCs.PGCs can form EBs by suspension culture,most of these EBs can differentiate into neuronal-like cells,they also can differentiate into epithelial-like and fibroblast-like cells in vitro.
