摘要: 目的

探究白细胞分化抗原83 (cluster of differentiation 83,CD83)和热休克转录因子5 (heat shock transcription factor 5,HSF5)鉴别生前、死后皮肤烧伤的法医学应用价值。

方法

通过逆转录实时定量聚合酶链反应(reverse transcription real-time quantitative polymerase chain reaction,RT-qPCR),定量检测生前及死后烧伤小鼠皮肤组织和人类皮肤组织中CD83和HSF5 mRNA的表达情况。

结果

与空白对照和死后烧伤组相比,生前烧伤组小鼠CD83和HSF5的mRNA水平明显升高,且死后96 h 可检测CD83 mRNA高表达,死后72 h可检测HSF5 mRNA表达。15例人类烧伤皮肤和未烧伤自身皮肤相比,11例样本CD83和HSF5的mRNA水平在烧伤处升高(P<0.05),4例没有变化。

结论

CD83和HSP5有望作为生前烧伤鉴定的生活反应指标应用于法医学实践。

Abstract: Objective

To explore the forensic application value of cluster of differentiation 83 (CD83) and heat shock transcription factor 5(HSF5) in identifying antemortem and postmortem skin burns.

Methods

Through reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR), CD83 and HSF5 mRNA levels in the skin tissues of antemortem and postmortem burned mice and human samples were detected quantitatively.

Results

Compared with the control group and the postmortem burned group, the mRNA levels of CD83 and HSF5 in antemortem burned mice were higher. The high mRNA expressions of CD83 could be detected 96 h after death, and the mRNA expressions of HSF5 could be observed 72 h after death. Compared with undamaged skin, increased CD83 and HSF5 mRNA levels were detected in 11 out of 15 cases(P<0.05).

Conclusion

CD83 and HSF5 can be used in forensic practice as indicators for vital reaction in antemortem burn identification.
