Methods: The relationship between the progression of Coxsarckie virus B3(CVB3) viral myocarditis and experimental autoimmune myocarditis and MIP-2γ mRNA expression in mouse was studied by TaqMan real-time fluorescent quantitative RT-PCR. Results: MIP-2γ mRNA expression rose on 3 to 5 d after CVB3 infection, reached peak on 7 d, and returned to normal level until 14 d, which corresponded well with the disease course. The MIP-2γ mRNA expression level rose significantly on the day 18 d after immunization with porcine cardiac myosin, which was consistent with pathological examination. Conclusion: MIP-2γ may be involved in the pathogenesis of myocarditis.展开更多
自然流产病因复杂,包括胚胎因素、母体因素、环境因素和免疫功能异常等,约50%~60%的流产与胚胎染色体异常有关。报告1例因2次自然流产行夫妇外周血染色体核型分析和荧光原位杂交(fluorescence in situ hybridization,FISH)检测的情况。...自然流产病因复杂,包括胚胎因素、母体因素、环境因素和免疫功能异常等,约50%~60%的流产与胚胎染色体异常有关。报告1例因2次自然流产行夫妇外周血染色体核型分析和荧光原位杂交(fluorescence in situ hybridization,FISH)检测的情况。妻子染色体核型未见明显异常,丈夫染色体核型46,XY,t(1;11)(p36.2;q24)。丈夫携带的t(1;11)平衡易位可能是导致该家庭反复流产的原因。该案例验证了FISH检测对于可疑亚端粒结构重排的应用价值。展开更多
