Discipline construction is an important part of the high-quality development of public hospitals.Under the current single multi-district development trend of public hospitals,it is necessary to layout disciplines in a scientific and systematic way to realize the coordinated development of each district at the geographical and functional levels.From the perspective of top-level design of multi-district discipline layout and practical exploration of Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine,it is proposed to clarify the functional orientation of the hospital districts from the perspective of the concept of running the hospital,national tasks and social needs.To achieve the high-quality development of the discipline and the continuous upgrading and innovation of public hospitals,it is also suggested to clarify the current situation of the discipline and determine the classified development direction by constructing a systematic disciplinary evaluation model.The transformation of scientific and technological achievements is a breakthrough to cultivate new momentum for the development of the hospital district,so as to realise the high-quality development of disciplines and the continuous upgrading and innovation of the functions of the hospital district.

Background Natural pyrethrins have long been widely used in the fields of environmental and household hygiene. Studies have reported that natural pyrethrins have potential liver toxicity, but their specific mechanisms are still unclear yet. Objective To explore the effect of natural pyrethrins on DNA damage in human liver cells. Methods This study used human liver cell QSG7701 as an in vitro testing model. After exposure to DMSO and a series of concentrations of natural pyrethrins (5, 10, 20, and 40 μg·mL⁻¹) for 6 and 24 h, reactive oxygen species (ROS) was detected by fluorescence microscopy using a fluorescence probe, thiobarbituric acid reactive substance (TBARS) by colorimetric method using a microplate reader, DNA damage by comet assay through observing DNA fragment migration under microscope, and phospho H2AX (γH2AX) and 8-oxoguanine (8-oxoG) by immunofluorescence assay using a laser confocal microscope. Results As the exposure concentration of natural pyrethrins increased, the fluorescence intensity of ROS significantly increased in a concentration-dependent manner. The differences in ROS between the 10 μg·mL⁻¹ and above groups and the control group were statistically significant (P<0.01), and the ROS levels in the 20 μg·mL⁻¹ and 40 μg·mL⁻¹ treatment groups were 2.17 and 3.05 times higher than that in the control group respectively. The TBARS level increased in a concentration-dependent manner in natural pyrethrins treated cells (P<0.01), and the levels in the 20 μg·mL⁻¹ and 40 μg·mL⁻¹ treatment groups were 2.46 and 3.01 times higher than that in the control group respectively. The results of comet assay showed trailing formation of cellular DNA in each dose group; as the exposure concentration of natural pyrethrins increased, indicators such as tail DNA content (TDNA%), tail length (TL), tail moment (TM), and Olive tail moment (OTM) increased in a concentration-dependent manner. Compared with the control group, the differences in the indicators between the 20 μg·mL⁻¹ and above groups and the control group were statistically significant (P<0.01), especially in the 40 μg·mL⁻¹ treatment groups, where TDNA%, TL, TM, and OTM were (46.92 ± 3.52) %, (64.67± 4.16) μm, 30.96 ± 2.94, and 22.64 ± 3.89, respectively. The cellular immunofluorescence results showed that natural pyrethrins induced the formation of γH2AX and 8-oxoG, the fluorescence intensities of γH2AX and 8-oxoG increased in a concentration-dependent manner, and the differences between the 10 μg·mL⁻¹ and above groups and the control group were statistically significant (P<0.01). Conclusion Natural pyrethrins could induce DNA damage in human liver cells, and ROS-mediated oxidative stress may play an important role in its liver cell genotoxicity.

Forensic science is looking for clues at a crime scene in order to reconstruct the crime scene.Classic clues include DNA and fingerprints.Forensic microbiology is a branch of forensic medicine that uses microbes as clues,providing us information about lifestyle,circadian rhythms,geographic locations,postmortem intervals,cancers,and oral or systemic diseases.Oral cavity,as the place with the second largest number of microorganisms,can provide researchers with microbial information of each ecological niche,and assist in the prediction,diagnosis and monitoring of oral or systemic diseases.This paper reviews the composition of oral microbiome,the application in oral diseases,systemic diseases and forensic medicine,with the aim of providing some references for the development of forensic microbiology based on oral microbiome.
