Objective: To research the method of Establishing model of polymyositis with damp-heat syndrome. Methods: 45 guinea pigs were randomly divided into three groups, group A (normal group), group B (experimental myositis group, control group), Group C (damp-heat group). In the control group, the rabbit skeletal muscle homogenate Garver,s complete adjuvant for subcutaneous immunization was used to injecting into the original guinea pigs. Besides the above-mentioned immune method, the heat-damp model method was used (feigan diet, hot and humid environment and pathogenic micro-organisms and other complex factors) to establish the polymyositis model with damp-heat syndrome. The general situations, such as the serum muscle enzymes, light microscopy, electron microscopy changes in each group were observed. Results: The results showed that the clinical performance, serum creatase, the pathological changes of skeletal muscle, lungs, liver of guinea pigs in damp-heat group were similar to the human polymyositis with damp-heat syndrome. Conclusion: The model can be used to study the human polymyositis with damp-heat syndrome, and provide the pathogenic and theoretical basis for treating polymyositis by TCM.

Objective To investigate the effect of propofol pretreatment on hippocampal monocyte chemotactic protein-1 ( MCP-1 ) and CC-chemokine receptor type 2 (CCR2) expression following forebrain ischemiarepcrfusion (I/R) in rats. Methods Twenty-four male SD rats weighing 250-300 g were randomly divided into 3 groups ( n = 8 each): group Ⅰ control; group Ⅱ I/R and group Ⅲ propofol pretreatment. Cerebral I/R was induced by clamping bilateral common carotid arteries for 10 min combined with hypotension ( MAP was maintained at 35-45 mm Hg) induced by exsanguinations in group Ⅱ and Ⅲ. In group Ⅲ propofol 50 mg/kg was injected into femoral vein immediately before cerebral ischemia. The animals were sacrificed at 6 h of reperfusion. Hippocampal tissue was obtained for detection of MCP-1 mRNA and CCR2 mRNA and their protein expression by RT-PCR and Western blot technique. Results I/R significantly increased the expression of MCP-1 and CCR2 in hippoeampal tissue as compared with control group. Propofol pretreatment significantly attenuated cerebral I/R induced increase in MCP-1 and CCR2 expression. Conclusion Propofol pretreatment can significantly inhibit forebrain I/R-induced hippocampal MCP-1 and CCP2 expression.
