No accepted standard currently exists to classify asphyxia and define its subtypes. Sauvageau and Boghossian proposed an asphyxia classification system in 2010 that divided asphyxia into suffocation, strangulation, mechanical asphyxia, and drowning. Here, we present a modification of this classification system. We propose to classify asphyxia into four main categories: suffocation, strangulation, mechanical asphyxia, and complicated asphyxia. Suffocation includes smothering and choking as well as confined spaces, entrapment, and vitiated atmosphere. Strangulation is subdivided into hanging, ligature strangulation, manual strangulation, and other unspecified strangulation. Mechanical asphyxia includes positional and traumatic asphyxia. Finally, complicated asphyxia is defined as cases with two or more identifiable mechanisms of asphyxia. In this study, we review autopsy cases from 2012 diagnosed as asphyxia and classify them according to our proposed asphyxia classification system. In 24.7% of cases, the age range was 40-49 years, and 51.9% were men. The most common method of asphyxia was hanging (245 cases, 55.1%), followed by ligature or manual strangulation (53 cases, 11.9%). Most hangings were suicides; smothering, ligature, and manual strangulation were usually homicides. Eighteen cases were complicated asphyxia. This classification provides a simplified, unified, and useful tool to classify and understand deaths due to asphyxia.

4.Review and analysis on the meridian research of China over the past sixty years.
Chinese journal of integrative medicine 2015;21(5):394-400
The meridian research situation and various meridian hypotheses of China in the past sixty years between 1950 and 2013 are summarized in the paper; possible existed problems in the process of current meridian research are analyzed. Based on previous research results, we proposed that the essence of meridian can not be explained by the reductive analysis method, meridian research should be carried out under the guidance of overall concept of Chinese medicine theory. In this paper, combined with coherence theory of biophoton, we put forward the quantum interference hypothesis of meridian, which provides a possible research idea for meridian study.

PURPOSE: To evaluate the predictability of amount of hemothorax in the patients with blunt chest trauma, supine chest AP radiographs of 66 patients were reviewed and statistically analyzed. MATERIALS AND METHODS: In 66 patients, rib fractures were present in 53 patients, hemothorax in 46 patients, pneumothorax in 25 patients, and pulmonary contusions in 18 patients. Width and length of hemothorax were measured on supine chest AP radiograph, and were correlated with known drained amount of hemothorax. The presence and number of rib fracture, pulmonary contusion, subcutaneous emphysema, fracture of scapula and clavicle, and total opacification of hemithorax were also correlated with the drained amount of hemothorax. RESULTS: In multiple logistic regression analysis, width of hemothorax had the highest correlation with drained amount of hemothorax(regression coefficient 0.718, p value 0.00005). The presence and number of rib fracture, scapular fracture, subcutaneous emphysema were also correlated with drained amount of hemothorax. But length of hemothorax, pulmonary contusion, clavicular fracture, total opacification of hemithorax were not correlated with drained amount of hemothorax. CONCLUSION: Measured width of hemothorax in supine chest AP radiograph is the most reliable predictor for estimation of the amount of hemothorax, and may also be used as an indication for the application of closed thoracostomy in the treatment of hemothorax.

Journal of Dental Hygiene Science 2024;24(3):160-170
Background:
This study aimed to analyze trends in qualitative research within the field of dental hygiene, focusing on paperspublished in Korean journals from 2000 to 2023. As dental hygienists play a crucial role in preventive oral health, understanding the breadth and depth of qualitative research in this field is essential for advancing practice and education.
Methods:
This descriptive survey research study analyzed 23 qualitative studies using the Consolidated Criteria for ReportingQualitative Research (COREQ) as a framework. Studies were selected through a comprehensive search of Korean databases. The analysis covered research topics, participant types, methodological approaches, and adherence to COREQ domains, including“Research Team and Reflexivity,” “Study Design,” and “Analysis and Findings.”
Results:
The analysis revealed that most studies employed a phenomenological methodology (36.4%). Additionally, 87.0% of thestudies mentioned Institutional Review Board (IRB) approval and only 8.7% utilized qualitative data analysis software. The studies primarily focused on oral care for the elderly, communication, and the experiences of dental hygienists. Furthermore, 95.7% of the studies included participant quotations, but only 56.5% checked data saturation.
Conclusion
This study highlights the need for a more diverse methodological approach in dental hygiene research. Journalsshould also emphasize strict adherence to IRB guidelines and encourage the use of qualitative data analysis software to enhance the rigor of research. By strengthening the systematic foundation of qualitative research in dental hygiene, the field can better address clinical challenges and expand the understanding of dental hygienists’ work environments.

Objective:To investigate the expression of inositol 1, 4, 5-triphate receptor (IP 3R)-glucose-regulated protein 75 (Grp75)-voltage dependent anion channel 1 (VDAC1)-mitochondrial Calcium uniporter (MCU) Calcium axis molecules in proteinuria and to explore its upstream regulator. Methods:Sixteen Sprague Dawley rats were divided into control group (6 rats) and Adriamycin (ADR) group (10 rats). Nephropathy rat model was established by single injection of ADR through tail vein.The glomerular expression of IP 3R, Grp75, VDAC1, MCU and the activation marker of mammalian target of Rapamycin complex 1 (mTORC1) were analyzed by immunohistochemical staining.In cultured mouse podocyte, ADR was used to induce podocyte injury, and the Everolimus of different concentrations was applied for intervention.The expression of the Calcium axis molecules and apoptosis marker was analyzed. Results:Compared with control group, the glomerular expression of IP 3R (0.02±0 vs.0, P<0.001), Grp75 (0.04±0 vs.0, P<0.001), VDAC1 (0.04±0 vs.0.01±0, P<0.001), and MCU (0.05±0.01 vs.0.01±0, P<0.001) were significantly increased in ADR-induced nephropathy rats, and the activation marker of mTORC1 (0.57±0.01 vs.0.18±0, P<0.001) was increased as well.In cultured mouse podocytes, compared with control group, the expression of Grp75 (1.89±1.17 vs.0.16±0.08, P=0.001), VDAC1 (1.59±0.34 vs.0.20±0.07, P=0.006), and MCU (1.56±0.38 vs.0.46±0.35, P=0.014) were obviously increased in ADR induced podocytes, and the activation marker of mTORC1 (2.12±0.08 vs.0.39±0.09, P<0.001) was also increased.Compared with the ADR induced podocytes, the expression of Grp75 (0.26±0.20 vs.1.89±1.17, P=0.001), VDAC1 (0.40±0.26 vs.1.59±0.34, P=0.014) and MCU (0.60±0.32 vs.1.56±0.38, P=0.029) in podocytes treated with ADR and 1.0 nmol/L Everolimus were remarkably decreased, accompanied with the decrease of mitochondrial calcium [(2 664.00±140.57) U vs.(3 025.16±180.92) U, P=0.023] and apoptosis marker cleaved Caspase-3 (0.55±0.28 vs.1.48±0.45, P=0.011). Conclusions:The over-production of IP 3R-Grp75-VDAC1-MCU Calcium axis molecules accompanied with the hyper-activation of mTORC1 was involved in ADR induced nephropathy rats.mTORC1 inhibitor decreased the expression of Calcium axis molecules in mouse podocytes, which might involve in the mechanism of mTORC1 inhibitor′s effects on podocyte.
