OBJECTIVE:To investigate new thought and method for improving the practice teaching effect of pharmacy under-graduates under the collaboration of medicine and education. METHODS:The training objectives of pharmacist team,the current sit-uations and problems of teaching that existing in the institute of pharmacy and the requirement of talents in the work were summa-rized and investigated,and then reform targets and measures were put forward. RESULTS:Training for pharmacists tream gradual-ly movedcloser to clinical pharmacists in China.The teaching work in the pharmacy department of our hospital was relatively com-plete,including relevant teaching system,practice systems and processes,training program for clinical pharmacists and develop-ment of workflow;however,there still remained some problems,including lacking of professional quality training,suitable cours-es,effective interactive medical and education scientific assessment mode and no attention for the training of clinical thinking and school-university research thinking. The above-mentioned problems needed to be solved by reforming internship tutorial system and improving the contents,establishing the school-hospital united system,emphasizing the connection between schools and teaching bases,establishing integrated teaching evaluation system and assessment criteria,strengthening clinical experience and training for clinical thinking by the teaching mode of physicians and pharmacists. CONCLUSIONS:Strengthening the collaboration of medicine and education and improving the training standards and evaluation system are helpful for improving the practice teaching quality of pharmacy undergraduates.

The Coat protein and Maturase gene of E.coli bacteriophage MS2 was amplified by PCR,then the gene was cloned into pET32a to construct the intermediate vector pET32aCP.The conservative sequence of FMDV internal ribosome entry site(IRES) was cloned into the downstream of pET32aCP bacteriophage gene to construct the prokaryotic expression vector pCPES.The recombinant plasmid pCPES transformed into E.coli strain BL21(DE3) was induced to express with 1mmol/L IPTG.The expression products were purified by sucrose density gradient centrifugation.The expression products observed by TEM were circular viruslike particles,and the diameter of these particles was about 26nm.The stability of viruslike particles was detected,and the viruslike particles was identified by RTPCR.The results showed that the viruslike particles contain the FMDV IRES RNA and have good stability.The viruslike particles have great prospect as the standard and quality control in the area of RNA virus detection.

OBJECTIVETo observe the effect of using polytetraflouroethylene (e-PTFE) tube with self-Schwann cells implanted to repair facial nerve defect.
METHODSEnzymatic digest method was used to get pure Schwann cells in short time. The e-PTFE membrane tube was used to bridge the 1.0 cm defect of facial nerve and pure self-Schwann cells were injected into the tube. As control group, the e-PTFE tube without self-Schwann cells was used in the same way. Electric physiological and histological examinations were taken in different times.
RESULTSThe effect of nerve regeneration of the experimental group was better than control group at any time. The nerve conduction velocity of the experimental group was 29.70 m/s in the 16th week, while the control groups was 23.00 m/s respectively at the same time.
CONCLUSIONIt is possible to obtain sufficient active Schwann cells by enzymatic digest method. Using e-PTFE tube to bridge the defect of facial nerve with self-Schwann cells implanted can get effect of nerve regeneration.

A growing body of evidence has indicated the important role of autophagy receptors in directing ubiquitinated or non-ubiquitinated cargos towards autophagy. Autophagy receptors bind to LC3 (microtubule-associated protein 1 light chain 3) on phagophore and autophagosome membranes, and recognize signals on cargoes in the delivery system of autophagy. However, the diverse domains in the receptor structures determine that their roles would never be limited to autophagy. Up to date, increasing numbers of the receptor proteins have been demonstrated to serve as a molecular link or switch participating in autophagic degradation, apoptosis or cell survival signals. Here, we highlight the non-autophagic roles of these receptor proteins to draw attention to this growing research topic.

Leucine zipper tumor suppressor 2 (LZTS2) is a novel tumor suppressor gene that has been increasingly recognized in recent years. Currently, many studies illustrate that LZTS2 gene, the important candidate tumor suppressor gene, is already involved in the inhibition of tumorigenesis and aberrant proliferation of tumor cells, and other functions of tumor cells. Information from these stud-ies can contribute to the formulation of new strategies for the treatment of tumors.

Kinematical alignment during total knee arthroplasty is an emerging process, and draws more and more attentions from scholars. Knee joint is close to normal joint after TKA through kinematical alighment, which has good clinical results and functional scores, and not increase failure probility. Thus, it may increase joint stress of patella-femur joint, lead to patellar maltracking and increase abrasion. The paper summarized defination and basical principle, operative method, clinical outcomes and deficiency of kinematical alignment during total knee arthroplasty, in order to choose a better way for kinematical alignment during total knee arthroplasty.

Abstract:
Occupational epidemiology aims to explore the effect of occupational hazards on the health of workers and understand
,
their mechanisms. It plays an important role in occupational health and occupational medicine.Currently occupational
, ,
exposures in the workplace are complex and diverse and multiple factors affect workers´ health at the same time. Therefore it
is important to elucidate the pathogenesis of occupational disease caused by occupational hazards and implement early
- -
intervention. System epidemiology collects data on multi level exposure and multi omics information to conduct network analysis
-
on the relationship amongrisk factors. and to study the mechanisms of exposures and health outcomes based on multi level data.
, , , ,
Using the study design of system epidemiology occupational environmental lifestyle and social factors are combined as a
,
system to evaluate the health of workers which can better evaluate the adverse health effects caused by occupational hazards.
- , ,
The studies base on multi omics design will explore the pathogenesis of occupational diseases at the molecular cellular and
tissue levels to evaluate the impact of occupational hazards on workers´ health and to explore interventions from multiple
-
perspectives to reduce the occurrence of occupational or work related diseases.
