Analysis of relationship between injury and disease by cardiac functional indicators in hypertension rat after trauma / 法医学杂志

OBJECTIVE@#To observe the changes of cardiac functional indicators in spontaneously hypertension rats (SHR) suffered by struck injuries of soft tissues, form which to discuss the significance in relationship between injury and disease.@*METHODS@#SHRs were divided into four groups according to the degree, and whose thigh was struck with the homemade hit instrument. Then the blood pressure, heart rate as well as serum biochemical indicators (CK, CK-Mb, LDH, Cr, BUN, HBDH and AST) were examined. In addition, the morphological changes of heart, brain and kidney were also observed.@*RESULTS@#The observe values of heart rate and blood pressure of SHRs seemed have relation to the degree of damage, but there were no statistically significance between different hit degree groups. In terms of serum biochemical indicators, all seven indicators of the hit group had significant difference with that of the control group, and the AST CK, CK-MB levels were difference between the group of different strike degree.@*CONCLUSIONS@#Struck injuries of soft tissues can result in forepart damage of cardiac muscle. The biochemical indicators reflect the degree of injury, and they could be used as a type of objective enzymology indicators for analysis of the relationship between injury and disease in forensic practice.

Follow-up study on psychic and neuropathic delayed effects of acute organophosphorus pesticides poisoning / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To study the delayed effect on neuropsychopathy and its related factors after acute organophosphorus pesticides poisoning (AOPP).</p><p><b>METHODS</b>Two hundred and fifty-seven cases of AOPP in the observation period were chosen to follow-up 2 months later from the 4 county hospitals in Shandong Province where the incidence of organophosphorus pesticide poisoning is high.</p><p><b>RESULTS</b>Nine cases of organophosphate induced delayed polyneuropathy (OPIDP) were found and the incidence rate was 3.5%. The occurrence of OPIDP were related to the need for emergent artificial respiration, and the degree of poisoning, and the kinds of organophosphorus pesticides (Ops). The positive rate of symptoms of peripheral nerves, central nerves and psychogeny except auditory and visual hallucination after poisoning was significantly higher than that before (P < 0.05). The patient's situation of health, economy and work became statistically worse (P < 0.05).</p><p><b>CONCLUSION</b>We found some had delayed effects on neuropsychopathy after AOPP which could debase the patient's life quality. The control measure should be administered as early as possible.</p>
