Abstract
OBJECTIVES To explore the differential expression of messenger RNA (mRNA) in myocardial tissues of rats with sudden coronary death (SCD), and to provide ideas for the forensic identification of SCD. METHODS The rat SCD model was established, and the transcriptome sequencing was performed by next-generation sequencing technology. Differentially expressed genes (DEGs) in myocardial tissues of SCD rats were screened by using the R package limma. A protein-protein interaction (PPI) network was constructed by using the STRING database and Cytoscape 3.8.2 on DEG, and hub genes were screened based on cytoHubba plug-in. Finally, the R package clusterProfiler was used to analyze the biological function and signal pathway enrichment of the selected DEG. RESULTS A total of 177 DEGs were associated with SCD and were mainly involved in the renin-angiotensin system and PI3K-Akt signaling pathway. The genes including angiotensinogen (AGT), complement component 4a (C4a), Fos proto-oncogene (FOS) and others played key roles in the development of SCD. CONCLUSIONS Genes such as AGT, C4a, FOS and other genes are expected to be potential biomarkers for forensic identification of SCD. The study based on mRNA expression profile can provide a reference for forensic identification of SCD.

Abstract
BACKGROUND Depression is a common mental disorder and the diagnosis is still based on the descriptions of symptoms. Biomarkers can reveal disease characteristics for diagnosis, prognosis, and treatment. In recent years, many biomarkers relevant to the mechanisms of depression have been identified. This study uses bibliometric methods and visualization tools to analyse the literature on depression biomarkers and its hot topics, and research frontiers to provide references for future research. METHODS Scientific publications related to depression biomarkers published between 2009 and 2022 were obtained from the Web of Science database. The BICOMB software was used to extract high-frequency keywords and to construct binary word-document and co-word matrices. gCLUTO was used for bicluster and visual analyses of high-frequency keywords. Further graphical visualizations were generated using R, CiteSpace and VOSviewer software. RESULTS A total of 14,403 articles related to depression biomarkers were identified. The United States (34.81%) and China (15.68%), which together account for more than half of all publications, can be considered the research base for the field. Among institutions, the University of California, University of London, and Harvard University are among the top in terms of publication number. Three authors (Maes M, Penninx B.W.J.H., and Berk M) emerged as eminent researchers in the field. Finally, eight research hotspots for depression biomarkers were identified using reference co-citation analysis. CONCLUSION This study used bibliometric methods to characterize the body of literature and subject knowledge in the field of depression biomarker research. Among the core biomarkers of depression, functional magnetic resonance imaging (fMRI), cytokines, and oxidative stress are relatively well established; however, research on machine learning, metabolomics, and microRNAs holds potential for future development. We found "microRNAs" and "gut microbiota" to be the most recent burst terms in the study of depression biomarkers and the likely frontiers of future research.

Abstract
BACKGROUND The pathological diagnosis of sudden cardiac death caused by myocardial ischemia is a difficult problem. Relevant evidence shows that the expression of Egr-1 and c-fos undergo changes in the early stage of myocardial ischemia, but the detailed temporal variation of them is not clear. Therefore, the aim of this study was to observe the temporal changes in mRNA and protein expression of Egr-1 and c-fos in ischemic myocardium in rats. METHODS Sixty-six Sprague-Dawley rats were divided into the control group, the early myocardial ischemia (EMI) group, the sham operated group and the allergy group. The EMI rats were further divided into eight subgroups according to the different time points (30 min and 1, 2, 4, 8, 12, 24, and 48 h) after modeling. The mRNA and protein of Egr-1 and c-fos of each group were detected by real-time quantitative polymerase chain reaction and immunohistochemistry, respectively. RESULTS In the EMI group, Egr-1 mRNA in ischemic myocardium rose 30 min after ischemia and peaked at 2 h; the plateau was maintained up to 8 h after ischemia, and then returned to the baseline level at 12 h. The c-fos mRNA in ischemic myocardium demonstrated a consistent changing curve with that of Egr-1. The mRNA of Egr-1 and c-fos showed no significant changes in the control group, the sham operated group and the allergy group. Immunohistochemistry showed that Egr-1 protein in the myocardial ischemic area was slightly positive 30 min after ischemia, and then strongly positive at 4 and 8 h, decreased at 12 h, and was negative at 24 h. The changing trends of c-fos protein were almost the same as that of Egr-1. Immunohistochemistry of Egr-1 and c-fos protein were all negative in the control group, the sham operated group and the allergy group. CONCLUSIONS The mRNA and protein expression of Egr-1 and c-fos presented rapid and temporal changes after myocardial ischemia, and this may be helpful in distinguishing sudden death induced by myocardial ischemia from that of allergy.

Abstract
OBJECTIVES To study the expression change of pro-brain natriuretic peptide (proBNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in sudden death of coronary atherosclerotic heart disease, and to explore its application in forensic diagnosis. METHODS Myocardial and blood samples were collected from normal control group, sudden death of coronary atherosclerotic heart disease group and single coronary stenosis group (20 cases in each group). The expression of proBNP in myocardial samples were detected by immunohistochemical staining and Western blotting, and that of BNP mRNA were detected by reverse transcription PCR (RT-PCR). The content of NT-proBNP in plasma were detected by ELISA. RESULTS Immunohistochemical staining showed positive expression of proBNP in both sudden death of coronary atherosclerotic heart disease group and single coronary stenosis group. There was no positive expression in normal control group. For sudden death of coronary atherosclerotic heart disease group and single coronary stenosis group, the relative expression of proBNP protein and BNP mRNA in myocardial tissue and the NT-proBNP content in plasma were higher than that of normal control group (P<0.05). The NT-proBNP content in plasma of sudden death of coronary atherosclerotic heart disease group was higher than that of single coronary stenosis group (P<0.05). CONCLUSIONS In myocardial ischemia condition, the higher expression of proBNP in cardiac muscle cell shows that the detection of NT-proBNP in plasma can be useful to differentially diagnose the degree of coronary atherosclerotic heart disease and determine whether the sudden death due to coronary atherosclerotic heart disease.

Abstract
OBJECTIVES To explore the value of mast cell tryptase and brain natriuretic peptide(BNP) in the differential diagnostic of sudden death due to hypersensitivity and coronary atherosclerotic heart disease. METHODS Totally 30 myocardial samples were collected from the autopsy cases in the Department of Forensic Pathology, Shanxi Medical University during 2010-2015. All samples were divided into three groups: death of craniocerebral injury group, sudden death of hypersensitivity group and sudden death of coronary atherosclerotic heart disease group, 10 cases in each group. Mast cell tryptase and BNP in myocardium were detected by immunofluorescence staining and Western Blotting. RESULTS Immunofluorescence staining showed that the positive staining mast cell tryptase appeared in myocardium of sudden death of hypersensitivity group and coronary atherosclerotic heart disease group. Among the three groups, the expression of mast cell tryptase showed significantly differences through pairwise comparison (P<0.05); The expression level of BNP in sudden death of coronary atherosclerotic heart disease group were significantly higher than the sudden death of hypersensitivity group and death of craniocerebral injury group (P<0.05). The difference of the expression level of BNP between the sudden death of hypersensitivity group and the death of craniocerebral injury group had no statistical significance (P>0.05). CONCLUSIONS The combined detection of the mast cell tryptase and BNP in myocardium is expected to provide help for the forensic differential diagnosis of sudden death due to hypersensitivity and coronary atherosclerotic heart disease.

Abstract
AIM: To investigate the expression of mast cell tryptase and carboxypeptidase A in drug-related fatal anaphylaxis.
METHODS: The expression of mast cell tryptase and carboxypeptidase A in 15 autopsy cases of drug-related fatal anaphylaxis and 20 normal autopsy cases were detected. First, the expression of mast cell tryptase was determined in stomach, jejunum, lung, heart, and larynx by immunofluorescence. Different tissues were removed and fixed in paraformaldehyde solution, then paraffin sections were prepared for immunofluorescence. Using specific mast cell tryptase and carboxypeptidase A antibodies, the expression of tryptase and carboxypeptidase A in gastroenterology tract and other tissues were observed using fluorescent microscopy. The postmortem serum and pericardial fluid were collected from drug-related fatal anaphylaxis and normal autopsy cases. The level of mast cell tryptase and carboxypeptidase A in postmortem serum and pericardial fluid were measured using fluor enzyme linked immunosorbent assay (FEIA) and enzyme linked immunosorbent assay (ELISA) assay. The expression of mast cell tryptase and carboxypeptidase A was analyzed in drug-related fatal anaphylaxis cases and compared to normal autopsy cases.
RESULTS: The expression of carboxypeptidase A was less in the gastroenterology tract and other tissues from anaphylaxis-related death cadavers than normal controls. Immunofluorescence revealed that tryptase expression was significantly increased in multiple organs, especially the gastrointestinal tract, from anaphylaxis-related death cadavers compared to normal autopsy cases (46.67 ± 11.11 vs 4.88 ± 1.56 in stomach, 48.89 ± 11.02 vs 5.21 ± 1.34 in jejunum, 33.72 ± 5.76 vs 1.30 ± 1.02 in lung, 40.08 ± 7.56 vs 1.67 ± 1.03 in larynx, 7.11 ± 5.67 vs 1.10 ± 0.77 in heart, P < 0.05). Tryptase levels, as measured with FEIA, were significantly increased in both sera (43.50 ± 0.48 μg/L vs 5.40 ± 0.36 μg/L, P < 0.05) and pericardial fluid (28.64 ± 0.32 μg/L vs 4.60 ± 0.48 μg/L, P < 0.05) from the anaphylaxis group in comparison with the control group. As measured by ELISA, the concentration of carboxypeptidase A was also increased more than 2-fold in the anaphylaxis group compared to control (8.99 ± 3.91 ng/mL vs 3.25 ± 2.30 ng/mL in serum, 4.34 ± 2.41 ng/mL vs 1.43 ± 0.58 ng/mL in pericardial fluid, P < 0.05).
CONCLUSION: Detection of both mast cell tryptase and carboxypeptidase A could improve the forensic identification of drug-related fatal anaphylaxis.

Abstract
OBJECTIVE To explore the expression of tryptase and chymase in human lung tissue of anaphylactic shock and its value for forensic medicine. METHODS With ten carbon monoxide poisoning cases as control group, the levels of tryptase and chymase were observed by immunofluorescence and analyzed using the Image Analyze and the Image-pro plus 5.0.2. The positive mast cells were counted and the levels of the tryptase and chymase were calculated respectively. RESULTS There was a statistically significant difference (P < 0.05) for the tryptase and chymase concentrations in the lung tissue between the anaphylactic shock group and the control group. CONCLUSION The levels of the tryptase and the chymase expression are greatly increased in human lung tissue of anaphylactic shock, which may provide the morphological evidence and reference for the diagnosis of anaphylactic shock in forensic practice.

Abstract
OBJECTIVE To investigate the expression of intercellular adhesion molecular-1 (ICAM-1) mRNA in contused skeletal muscle of rats using fluorescence in situ hybridization (FISH) and its relationship with the contusion interval. METHODS To make the contusion models with rats skeletal muscle. The samples were taken to extract mRNA at 0.5 h, 1 h, 6 h, 12 h, 18 h, 24 h, 30 h and from the control group after contusion respectively. FISH was performed on frozen section samples and the sections were observed using LSCM. RESULTS The expression of ICAM-1 mRNA peaked at 6 h in skeletal muscle after contusion. Its level fell to 3.46 times the level of control group at 18 h and then increased again. CONCLUSION The time-order expression of ICAM-1 mRNA in 30 hours after contusion is potentially useful for estimation of early wound age.

Abstract
OBJECTIVE To observe the effects of berberin on insulin sensitivity in high fat diet rats. METHODS Before and after ingesting berberin, glucose insulin tolerance test was used to measure the insulin sensitivity, and determining fasting blood glucose, insulin, blood lipid and muscle triglyceride content. RESULTS Compared with normal feeding rats, high fat feeding impaired insulin action (5.02 +/- 1.08 vs 8.72 +/- 0.91, P < 0.005), decreased liver glycogen level and raised fasting blood glucose, insulin and blood lipid levels. Berberin and metformin improved insulin resistance (6.31 +/- 0.95 and 6.24 +/- 0.65) and liver glycogen level in insulin resistance models, but had no effect on blood glucose, insulin, lipid levels and muscle triglyceride depots. CONCLUSION It is confirmed that berberin could raise insulin sensitivity of high fat diet rats similar to metformin.

Abstract
We present herein clinical experience of neurosurgical anesthesia and cerebral protection in 66 cases, including 27 with supratentorial mass, 28 posterior fossa tumor and 11 cerebral vascular deformity. Our methods for the control of intracranial pressure (ICP) and cerebral blood flow (CBF) during neurosurgical anesthesia were as follows: (1) avoidance of the drugs adversely influenced on ICP; (2) use of lidocaine iv. infusion; (3) prevention of hypercapnia; (4) maintenance of adequate perfusion of vital organs; (5) drainage of cerebrospinal fluid if necessary; (6) use of free radical clearing agents. We conclude that they are key points of effective control of ICP and maintenance of CBF so as to prevent cerebral ischemic effect on neurological function.
