50 000 bp)was extracted from frozen gastric cancer tissue and their corresponding normal samples and used for RLGS assay.The genome DNA was digested by methylation-sensitive restriction enzyme Not Ⅰ, and labeled by radioisotope ~(32)p,then separated by two-dimensional electrophoresis and autoradiography. Experimental conditions for each step were optimized step by step.DNA fragment sequences for the dots on scanning profile were identified according to the human RLGS database.Results RLGS assay was set up and used to get the RLGS profiles of the representative tested samples successfully.These profiles can display more than 1 200 available dots averagely,the profiles of high quality DNA sample can display more than 1 800 dots which is the average level at an excellent RLGS lab,discrepant dots which had weaken or enhanced signals and their sequence information were obtained.The result can be reproduced.Conclusion The RLGS assay is established,stabilized for detection of DNA methylation of tissue samples.

The reproduction of Helicoverpa armigera nucleopolyhedrovirus in the midgut epithelia cells and the other sensitive tissues was observed by electron microscopy. The reproducing viruses in the midgut epithelia cells were mostly without envelopes, and thte polyhedrons were seldom formed. The reproduciing viruses in the other sensitive cells were with envelopes, and packed in polyhedrons.

Objective To investigate effects of Kanglaite injection on proliferation, cycle and apoptosis of human breast cancer MCF-7 cells;To discuss its relevant mechanism. Methods Logarithmic growth phase cells were divided into control group and Kanglaite-treatment group (10, 20, 40μL/mL). Cells were cultured in RPMI-1640 for 24 h before drug treatment. The inhibition rate of Kanglaite injection on proliferation of human breast cancer MCF-7 cells was detected by MTT assay. Apoptosis and cell cycle of MCF-7 cells were detected by flow cytometry. Changes in cell nucleus were determined by Hochest staining assay. Protein expressions of Bcl-2 and Bax were detected by ELISA and Western blot. Results Kanglaite injection for 12 h, 24 h or 48 h resulted in a significant inhibition of MCF-7 cells proliferation (P<0.05, P<0.01);Compared with the control group, Kanglaite injection-treated cells showed increased percentage in G2/M and G0/G1 phases (P<0.001, P<0.01), but showed decreased percentage in S phase (P<0.01), and apoptosis rate increased (P<0.05, P<0.001). Kanglaite injection significantly decreased protein expression of Bcl-2, and enhanced protein expression of Bax of MCF-7 cells (P<0.01, P<0.001). Conclusion Kanglaite injection can inhibit the proliferation of human breast cancer MCF-7 cells, decrease cell cycle and induce apoptosis, the mechanism is related with decreasing protein expression of Bcl-2 and enhance the protein expression of Bax.

AIM:To construct hybrid nucleic acid vaccines which contain Plasmodium falciparum merozoite surface protein 1 (MSP1 ) block 1 7gene and gene fragment coding for several T cell epitopes. METHODS:MSP1 block 1 7gene of FUP strain was connected with a polyvalent gene fragment which contains several T cell epitopes from MSA1 ,MSA2 ,RESA,IL- 1 and Tetanus toxin,the connected gene fragment (hybrid gene,HG) was cloned into eukaryotic expression plasmid p CDNA3.1 (- ) ,VR1 0 1 2 for intracellular expression,VR1 0 1 2 /TPA for secretion,the recombinants were identified by PCR and restriction enzyme digestion. RE- SUL TS &CONCLUSION:The hybrid nucieic acid vaccines:VR1 0 1 2 /HG,VR1 0 1 2 /TPA/ HG and p CDNA3.1 /HG were successfully constructed.

In recent years, there has been a comprehensive reform of higher medical education in the Medicine School of Wuhan University. According to the need for reform, the teaching of neurology has to be changed from the traditional form to a new form, and be integrated into the clinical pathophysiology and therapeutics (CPPT) courses. Currently neurology in CPPT takes the form of theoretical lectures, case discussions, combined with practical lessons to observe sections under the microscope and clinical practice, for the cultivation of students'!self-learning ability and clinical thinking. In the commissioning process, it exposes some problems in teaching process due to the characteristics of the course in neurology. For example, the knowledge of neuroanatomy is insufficient and review lessons relatively too short, and the teaching effect may be worse due to the fact that teachers have busy clinic work. In addition, students participate in case discussions with less enthusiasm. To solve these problems, we take some measures to promote teaching reform in neurology, such as increasing the review hours of neuroanatomy section in the CPPT neurology, training a group of specialized medical teachers to enrich and stabilize teacher team, adjusting the content and form of discussion class to improve students'!interest and participation, and increasing assistant jobs by the student to assist discussion teaching.
