Interaction in classroom teaching is a bilateral activity that is difficult to control. Teachers and students are the two main aspects to realize the synchronization of teachers and students' thinking. For teachers, teachers should first make full use of multimedia resources, bring a colorful courseware into class-room teaching; secondly, teachers should stimulate students' interest in a reasonable way, so as to inject vitality into the classroom teaching; finally, teachers should mobilize the students' thinking and carefully regulate the changes in thinking between teachers and students through a proper teaching methods. In terms of students, students should not only give full play to their initiative, but also actively cooperate with teachers in order to realize the thought synchronization between teachers and students in classroom teaching and learning interaction and ultimately achieve the desired results.

The adjustment of Laboratory Medicine to the first class subject is both challenges and opportunities. In order to meet the requirements of the modern laboratory medicine on the improved knowl-edge and skill, Weifang Medical University sets a goal of cultivatinghigh-qualified and applicative profes-sional personnel of Laboratory Medicine Science. To realize that, we build a new curriculum system with features of Medical Laboratory Science, including the theoretical curriculum system and the practical teach-ing system. The theoretical curriculum system breaks the traditional framework of the old curriculum which designed according to the discipline category, builds a new curriculum system of platform and module, scientifically integrates the basic course group in clinical laboratory medicine, and adds the course of clinical examination skills with its own professional characteristics. In the practical teaching system, we focus on the cultivation of practice ability and innovation ability, encourage the students to go to the hospital and company earlier, and promote the integration of production, teaching and research in various approaches.

Objective To explore the T‐SPOT .TB technology in latent tuberculosis infection (LTBI) who immunosuppres‐sive therapy results in screening for latent tuberculosis infection prevention and control to provide a new basis .Methods Applica‐tion of T‐SPOT .TB kit 162 immunosuppressed patients need to be applied to detect M .tuberculosis‐specific T cells ;while doing all cases tuberculin (TST ) skin test ;of which 28 cases of T‐SPOT .TB‐positive patients before screening technique using anti‐TNF‐αbiologics were given prophylactic treatment of anti‐TB drugs for 4 months and followed a year .Results The positive rates and ac‐curacy rate of T‐SPOT .TB assay were 36 .4% and 94 .9% ,while the positive rates and accuracy rate of TSTs were 28 .4% and 69 .6% .The difference between T‐SPOT .TB assay and TST were statistical significance(P < 0 .05) .Through our 28 cases of T‐SPOT .TB positive screening technology ,prophylactic anti‐TB drugs to treat patients for 4 months and 1 year of follow‐up ,no case of tuberculosis occurred .Conclusion These results demonstrate that the performance of T‐SPOT .TB is better than the classic TST for detection of LTBI in patients receiving immunosuppressive therapy for treatment of systemic autoimmune disorders .The T‐SPOT .TB assay will be a useful tool in early and rapid diagnosis of latent tuberculosis infection .T‐SPOT .TB for LTBI patients di‐agnosed with prophylactic anti‐TB drug treatment is necessary ,has important clinical significance .

Rabies is a deadly zoonos caused by rabies virus, the case fatality almost is 100%following suffering from this dis-ease.Recently, the incidence of rabies tends to increase in China.A rapid, accurate, economical, simple and convenient, easy to be widely used method for rabies virus detection in laboratory is urgently needed.This paper reviews the nucleic acids diagnosis techniques of rabies virus from the nucleic acids detection methods based on PCR, NASBA, LAMP, Genechips and analyzes the advantages and disadvantagesof the above-mentioned methods, which provides a reference for rapid laboratory diagnosis of rabies virus to efficently prevent and control rabies.

ABSTRACT:The aim of the present study was to investigate the inhibitory effects of TLR7 on Mycobacterium tuberculosis . TLR7 on infected RAW264 .7 cells was activated by chemical synthesis of TLR7 activation motif ssRNA .Activated RAW264 .7 cells were inoculated with Mycobacterium tuberculosis ,quantitative PCR method was applied to detect the phagocytosis rate of cell to bacteria at different time after infection .Cytokine production was measured by ELISA from cell supernatant .Cells were cultured on Roche medium and counted after sterile cracked with TritonX‐100 and diluted with PBS .Scanning electronic micro‐scope ( SEM ) was applied to detect the morphological changes of cells treated with TLR7 activation motif ssRNA .The highest phagocytosis rate of bacteria of RAW264 .7 cells was at 3 hours post infection (P>0 .05) .Compared with that of the control group ,treatment after 36 hours intracellular bacterial quantity in ssRNA treated group was lower (P<0 .05) ,levels of IL‐12 (P<0 .05) and IL‐4 (P<0 .05) were increased .For treatment after 48 hours ,level of IL‐4 (P<0 .05) was decreased ,and TNF‐α (P<0 .05) was increased .For treatment after 3 hours ,cell morphology of the ssRNA group was obviously better than the control group and appeared lots of phagosomes .Results suggested that TLR7 could enhance macrophages in killing Myco‐bacterium tuberculosis by forming phagosomes and regulating cytokines production ,and TLR7 activation motif ssRNA could be used in the treatment of tuberculosis .

The culture of modern medical talents is the requirements of the times on cultivating talents of Medical Laboratory of Medical College. In order to establish a high level teaching team and im-prove the quality of teaching and personnel training, through the reform of the traditional teacher training way, we created the teacher training mode of multi echelon teachers including department, university, domestic and international training ways. New curriculum teaching system framework was established which was based on theoretical teaching, practical teaching and scientific research. Besides, innovative and pro-gressive practice teaching platform was set up which included basic experiment, clinical skills, professional training, and practice in company. Course of Clinical Examination Skills was opened. The teaching team achieved some results in the above teaching reform.

OBJECTIVE: To determinate the catalpol contents in dried rehmannia root and Taohong Siwu Decoction containing rehmannia root with high performance liquid chromatography (HPLC). METHODS: Catalpol was separated on a YWG-C18 column using water-acetonitrile (99.4:0.6) as mobile phase and detective wavelength at 210 nm. RESULTS: The linear curve of tested catalpol concentration within the range of 0.0536-5.3600 microg/microl was ideal (n=5, r=0.999 7). The average recovery rate of the dried rehmannia root and Taohong Siwu decoction was 98.7% (RSD=0.48%) and 98.2% (RSD=1.29%) respectively. CONCLUSION: HPLC method is accurate and valuable for the quality control of Radix Rehmanniae and Taohong Siwu Decoction.
