Objective:Based on postmortem pericardial fluid of relevant biochemical values change to clear forensic pathology is concerned with the sudden cardiac death (myocardial infarction) identification of the possibility; To explore factors influencing the pericardial fluid change after death; Statistics in the pericardial fluid after the death of the body, the change rule of biochemical indicators provide a pericardial fluid biochemical values after the death of the body change the basis of the data; The change rule of biochemical indicators provide a pericardial fluid biochemical values after the death of the body change the basis of the data, provide more scientific basis for forensic pathology identification. Methods:Forensic pathology to collect samples in the case of the human body60cases of pericardial fluid samples, by automatic biochemical analyzer test aspertate aminotransferase(AST), sodium ion(Na+), potassium ion(K+), chloride ion(Cl-), calcium ion(Ca2+), creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH) and lactate dehydrogenase isozymes (LDH1), hydroxybutyrate dehydrogenase (HBDH), troponin I (cTn-I) a total of11indexes, get the data, using the SPSS17.0package analysis.Results:According to the cause of death is divided into cardiac disease group (n=20), the non-cardiac disease group (n=20), no disease control group (n=20).â‘ AST: Cardiac disease and non-cardiac disease group has no statistical significance (P>0.05), cardiac disease group compared with no disease control group was statistically significant (P<0.01), the cardiac disease group compared with no disease control group was statistically significant (P<0.05).â‘¡Na+, K+, Cl", Ca2+:Pairwise comparison between three groups have no statistical significance (P>0.05).â‘¢CK, CK-MB, HBDH, cTn-I:Cardiac disease group, non-cardiac disease group and no disease control group pairwise comparison between three groups have statistical significance(P<0.01).â‘£LDH, LDH1:Cardiac disease group and non-cardiac disease group, no disease control group is obvious higher, significant difference(P<0.01), the non-cardiac disease group and no disease control group is significant difference (P<0.05). Conclusion:1, cardiac disease group and non-cardiac disease group, no disease control group to compare the CK, CK-MB, LDH, LDH1, HBDH, cTn-I has statistically significant, six indicators of joint detection for the diagnosis of acute myocardial infarction to provide more value.2, the AST between cardiac disease and non-cardiac disease group is no statistical significance, the AST no disease control group to compare cardiac disease and non-cardiac disease group was statistically significant.3, cardiac disease group and non-cardiac disease group, no disease control group to compare the K+, Na+, Cl-, Ca2+has no statistically significant.4, factors such as time of death, the blood pollution, corruption has influence to the pericardial fluid biochemical values, biochemical values of testing should be performed as early as possible. |
