Patent competition has become one of the key issues of global competitions in economy,science and technology. In hospitals, the patent management strategy provides guidance for and impels knowledge innovation. However, hospital management is quite weak in China, which may have been caused by various reasons, such as the over enthusiasm for published paper and the technological achievement contrasted with negligence in patent application and exploitation. In the paper, countermeasures are proposed,which include the whole process management during the scientific research, setting up detail targets and standard procedures for patent management, training patent management staff, et al.

The management of hospital medical periodicals is now facing many realistic problems such as management system of editorial department, ability of editorial team, quality of articles and outside living environment. Co-publishing periodicals with pharmaceutical enterprises, with foreign publications and innovating publishing model of periodicals have been adopted by some domestic hospitals. By studying cases of periodical management innovation, and summing up the latest domestic point of view on medical periodical management, this paper held the view that the hospital medical periodicals management should be grouped into the framework of hospital scientific research management. Basically, the hospital should focus on solving the problem of management system in priority;developing in a way of specialization, collectivization and brand-orientation;establishing of a high-level editorial team;strengthening international communication and publishing periodicals according to international rules.

Currently,research and practice in the of hospital management in China are at low level.This paper agrees that the innovation of hospital research management should be based on scientific knowledge management,knowledge communities is a core component of knowledge management implementation in hospitals.This paper descripts the method that how to buide the knowledge community,for example,the types of knowledge community,hospital knowledge system,and the job title based knowledge map and process-oriented knowledge map.

Clinical work is the core of a hospital. The level of the clinical work and scientific research are the major indexes for the evaluation of a hospital or a clinician. However, there seems contradiction between the clinical work and scientific research. For hospital administration and clinicians, it is important to adopt clinical work as the center, and conduct research around the clinical practice, which will facilitate the transition from the scientific research to clinical application. Eventually the clinical work will improve and medical science will develop.

The genetic analysis of herpesviruses has been a constant challenge, due to the large, complex genomes of herpesviruses and mutagenesis of viral genes by conventional recombination methods in cell culture. Recently, a completely new approach for full-length infectious clones of herpesviruses based on bacterial artificial chromosomes (BACs) has been developed. This technique allows the maintenance, propagation and genetic modification of the viral genome as a BAC plasmid in E.coli, thus making the procedures fast, safe and effective in prokaryotic cells. This technique also makes it possible for the reconstitution of viral progeny or mutants by transfection of the BAC plasmid into eukaryotic cells, thereby facilitating the analysis of viral gene functions in the context of genome. In this presentation, Epstein-Barr virus was used as an example to describe the principle, establishment of the technique and mutation introduction into the BAC plasmid, and to discuss the perspective in the use of BAC-cloned herpesviruses.

Objective To evaluate the diagnostic value of serum M-type phospholipase A2 receptor(PLA2R) antibody detection for the diagnosis of idiopathic membranous nephropathy(IMN) by meta analysis.Methods By searching the databases of PubMed,Emabse,Wanfang and CNKI from inception to May,2017,all the literatures referred to serum PLA2R antibody for the diagnosis of IMN in both English and Chinese were reviewed and selected according to the inclusion and exclusion criteria.QUADAS was used to assess the quality of eligible studies.Meta-disc 1.4 was used to analyze heterogeneity and pooled effectsize and Stata 12.0 was used to analyze publication bias.Results A total of 20 studies with high quality were included.Heterogeneity test indicated there was no threshold effect.The pooled sensitivity was 0.69 (95 ％ CI:0.67 to 0.72),the pooled specificity was 0.97 (95 ％ CI:0.96 to 0.98) and the summary area under curve was 0.880.Sensitivity analysis indicated that the result was stable.Deek's funnel plot indicated there was no publication bias.Conclusion The sensitivity of detection of serum PLA2R antibody was acceptable for the diagnosis of IMN with high specificity,so more attention on PLA2R antibody should be paid in the clinical practice.

Epstein-Barr virus (EBV) is a human herpesvirus associated with important human diseases, including infectious mononucleosis syndrome, malignant lymphoma, and nasopharyngeal carcinoma. The mechanism of EBV entry into host cells remains a subject of intensive research. After decades of study, researchers have identified several key proteins and different patterns of EBV intrusion into host cells. The viral surface glycoproteins, gp350/220, gp42, gB, gH, and gL, are involved in interactions with the CR2 receptor on the surface of B lymphocytes during viral entry. However, the majority of epithelial cells lack CR2 receptor expression, which makes viral invasion much more complex than in B lymphocytes. Three different models have been proposed to explain how EBV enters epithelial cells: (1) "transfer of infection", mediated by B lymphocytes or Langerhans cells; (2) EBV utilizes its own proteins during the process of fusion with the cell membrane; and (3) progeny virions arising from EBV-infected epithelial cells cross lateral membranes into adjacent epithelial cells. This review will discuss the relevant mechanism of viral entry into B lymphocytes and epithelial cells during EBV infection.

To obtain a number of penicillinases and degrade penicillin in milk by using the penicillinases,the gene encoding penicillinase was amplified by PCR from Bacillus cereus ATCC10987,cloned into pET28a(+) ,transformed into E. coli BL21;analysis of SDS-PAGE and penicillinase activity of the recombinant protein were done under induction of IPTG and the result showed that the maximum penicillinase activity reached 480 U/mL;the purity of penicillinase purified by Ni2+ Purification System was more than 90%;the immobilized penicillinases were obtained by sodium periodate method and the residual quantity of penicillin in milk(containing 0.5 U penicillin G/mL) was less than 4 ppb after degraded by the immobilized penicillinase.

Objective To report the clinical effect of primary percutaneous coronary intervention(PCI)in patients with acute myocardial infarction(AMI).Methods A retrospective study was accomplished on the clinical data of 13 AMI patients who underwent PCI from March 2004 to April 2006.Results The infarct-related artery (IRA)was successfully recanalized by primary PCI for 12 AMI patients,without major complications occurred in these cases during hospitalization.Conclusion Primary PCI should be firstly chosen for treatment of AMI in the hospitals which could carry out PCI.
