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.

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.

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.

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 .

This paper proposed the idea of building cultivation mode of high quality medical talents in curriculum teaching by taking medical microbiology course as an example and pointed out that this can be implemented from updating education and teaching ideas,strengthening comprehensive qualities of teachers,optimizing and integrating teaching contents,reforming class teaching structure and improving teaching methods etc.

In order to adapt to the requirements of modem medical knowledge and skills for higher medical workers,and to cultivate medical students' molecular medicine quality and comprehensive ability,Weifang Medical University broke the boundaries of disciplines and constructed experimental course group in molecular medicine based on the ideas of curriculum group construction.Molecular medical knowledge was integrated into the teaching process of experimental course group,experimental teaching content system was reasonably integrated and optimized,high quality teaching team was set up,multi-level experimental teaching platform was built and student-centered teaching mode was implemented to explore the experimental teaching approach which helped medical students to form systematic molecular medicine knowledge structure and ability structure.

Objective To amplify the higA gene from the Mycobacterium tuberculosis,and to analyze the structure and function of their encoded proteins by using bioinformatics.Methods Total DNA was extracted from Mycobacterium tuberculosis.PCR of higA was performed and the products were sequenced.The biological features of the higA protein including,its physical and chemical properties,signal peptide,spatial structure and epitopes were analyzed by using software online.Results The PCR products of higA were 450 bp in length,which were consistent with the expected size.The higA protein consisted of 149 amino acids and had the following characteristics:a theoretical isoelectric point of 7.93,a fat-soluble factor of 94.30,and instability coefficient of 36.57.The higA protein had no signal peptide,containing 10 phosphorylation sites and multiple potential epitopes.Conclusion Mycobacterium tuberculosis higA gene can be amplified by PCR and the characteristics of higA protein is identified.

AIM: To develop the methods for the quantitative analysis of gallic acid and total phenolic acid in Sedum Aizoon L. METHODS: Gallic acid was analyzed by HPLC on a Hypersil BDS C_(18) column and detected at 271 nm.The mobile phase was methol-water(adjusted to pH=3.0 with H_3PO_4)(90∶10)at a flow rate of 1.0 mL/min.Total phenolic acid was analyzed by spectrophotometry at 720 nm.The colour-developing agent was the mixture solution of 0.6%FeCl_3—0.9%K_3[Fe(CN)_6](1∶0.9). RESULTS: Calibration graphs were constructed in the range of 0.343 0-1.200 ?g(r=0.999 7) for gallic acid and 0.4640-2.320 ?g/mL(r=(0.999 3)) for total phenolic acid.The average recoveries were 97.91%(n=6) for gallic acid and 99.21%(n=6) for total phenolic acid.The RSD of the methods were 1.8% and 2.0%,respectively. CONCLUSION: The methods were fast,reliable,accurate and suitable for analysis of gallic acid and total phenolic acid and quality control in Sedum Aizoon L.
