Forensic Progress on Death Following Carotid Sinus Inhibition
Death after carotid sinus trauma is usually attributed to death from inhibition, a type of sudden death. Currently, the number of incidents is scarce, and related studies are few. Therefore, how to determine the involvement of carotid sinus and determine the role of diseases in the cause of death has always been a difficult point in forensic investigation. This article sorts out the research literature on carotid sinus related death at home and abroad in recent years, systematically reviews the anatomic structure of the carotid sinus nerve, the clinical epidemiology of carotid sinus syndrom
Research Progress on Estimation of Postmortem Interval Using mRNA and ncRNA
Postmortem interval (PMI) estimation has always been an important and difficult issue in the field of forensic pathology. In recent years, research progress on the estimation of PMI using RNA specific variation patterns after death has been made by researchers at home and aboard. This paper summarizes the specific application methods of messenger RNA and non-coding RNA for PMI estimation based on the literatures and discusses the existing problems and development trends, in order to provide technical reference for related studies and estimation practice.
Sex Estimation of Typical Adult Vertebrae Morphology in Central China Based on CT Technique
The morphological data of the second thoracic vertebra and the third lumbar vertebra were measured by computerized tomography (CT). The sex differences were analyzed and the discrimination equation was obtained. The data of 274 adults (203 cases from experimental group and 69 cases from validation group) from central China were collected. Four linear data (maximum transverse length of vertebral body, maximum longitudinal length of vertebral body, maximum transverse length of vertebral foramen, maximum longitudinal length of vertebral foramen), one angle data (angle between spinous processes
Research Progress on Multiple Organ Damage and Mechanism of Cantharidin Poisoning
Cantharidin poisoning has been proven to cause multiple organ damage. Acute circulatory failure, acute renal failure, and multiple organ failure resulting from cantharidin poisoning are the main causes of death for patients with cantharidin poisoning. However, research on the damage of main target organs and mechanism of cantharidin poisoning is not clear. This paper reviews the latest toxicological and pathological research literatures at home and abroad related to cantharidin poisoning and comprehensively summarizes the latest research progress on the toxicological and pathological damage
Frequency Characteristics of AEPs in Normal Young Adults and Comparison of Their Response Threshold and Pure Tone Audiometry Threshold
The tests of three types of auditory evoked potentials (AEPs) were performed on normal young adults, to understand the frequency characteristics of different testing methods and the relationship between response threshold and pure tone audiometry threshold of different methods, and to discuss the forensic value of 3 types of AEPs to evaluate hearing function. Methods Twenty normal young adults were selected, their standard pure tone audiometry threshold, short-term pure tone audiometry threshold and the response threshold of 3 types of AEPs (tone burst-auditory brainstem response, 40 Hz aud
