Abstract Adolescents are a high risk group for non suicidal self injury (NSSI), and the severity of the issue has been increasing. However, stigma originating from self perceptions, the public, and healthcare professionals poses significant barriers to help seeking and recovery among adolescents with NSSI. The paper systematically reviews the main intervention strategies targeting NSSI related stigma in adolescents, along with their effectiveness, from three perspectives: educational approaches, contact based interventions, and public advocacy against stigma, aiming to inform the development of a scientific, effective, and multi stakeholder collaborative integrated intervention framework to provide a basis for reducing and ultimately eliminating stigma associated with adolescent NSSI.

The mandibular condyle is a critical growth center in craniofacial bone development, especially during postnatal stages. Postnatal condyle osteogenesis requires precise spatiotemporal coordination of growth factor signaling cascades and hierarchical gene regulatory networks. Plagl1, which encodes a zinc finger transcription factor, is a paternally expressed gene. We demonstrate that PLAGL1 is highly expressed in cranial neural crest cell (CNCC)-derived lineage cells in mouse condyles. Using the CNCC-derived lineage-specific Plagl1 knockout mouse model, we evaluate the function of PLAGL1 during postnatal mouse condyle development. Our findings show that PLAGL1 contributes significantly to osteoblast differentiation, and its deficiency impairs osteogenic lineage differentiation, which consequently disrupts mandibular condyle development. Mechanistically, insulin-like growth factor 2 (IGF2) in complex with IGF-binding proteins (IGFBPs) has been identified as the principal PLAGL1 effector responsible for osteogenic regulation during postnatal condyle morphogenesis. Plagl1 deficiency significantly downregulates the IGF2/IGFBP pathway, leading to disordered glucose metabolism, defective extracellular matrix organization, and impaired ossification. Exogenous IGF2 treatment rescues impaired osteoblast differentiation caused by Plagl1 deficiency. In conclusion, the PLAGL1-IGF2 axis is a critical regulator of osteogenesis during mandibular condyle development.

Objective To analyze the adverse reaction reports （ADRs） of drug-induced liver injury in recent ten years, explore the characteristics and related rules of drug-induced liver injury, and provide reference for clinical safe drug use. Methods ADRs in our hospital from 2011 to 2021 which belonged to drug-induced liver injuries were collected, and Pareto analysis was carried on. Results In 259 ADR reports, the most common type of drug-induced liver injury was hepatocellular injury （37.84%）. The age of drug-induced liver injury was mainly over 46 years, totaling 195 （75.28%）. Drugs were mainly distributed in cardiovascular system medicine （44.02%）, anti-infective medicine （23.94%）and anti-tumor medicine （11.58%）. Among the cardiovascular drugs, atorvastatin calcium 40mg and over 40mg were the highest proportion, with 53 cases （46.49%）. The main anti-infectious drugs were cephalosporins （29.03%）, carbapenem （19.35%）， antifungal （17.74%）and quinolones （11.29%）. Adverse reactions occurred within 6 days （69.88%）, the duration of adverse reactions was 1-2 weeks （31.66%）, and most patients were improved （47.88%） or cured （37.07%）. Conclusion For middle-aged and elderly patients, when the application of cardiovascular system drugs, anti-infective drugs or anti-tumor drugs, it is necessary to monitor the liver function changes of patients for at least 6 days. If there are abnormalities, the drugs should be stopped or given treatment in time, to avoid the progress of drug-induced liver injury.

"Toxicity Testing in the 21st Century—A Vision and Strategy"proposed by the National Research Council of US has brought innovative directives and objectives for toxicity evaluation and risk assessment,pushing forward the next generation of toxicity testing and risk assessment.In this initiative,the concept of adverse outcome pathways(AOPs)has emerged as a prominent methodology,capturing the attention of toxicologists and researchers due to its promising applications in recent years.The quantitative AOP(qAOP)is an extension of the adverse outcome pathway,which is built upon the foundational qualitative adverse outcome pathway model and leverages mathematical frame-works to depict dose-response and/or response-response relationships.This article reviews the princi-ples and advancement surrounding qAOP,introduceds two prevalent methodologies for constructing qAOP,Bayesian network models and regression models,and demonstrates diverse applications of qAOP.Actual cases are used to underscore the transformative role of qAOP in contemporary toxicology and risk assessment practices.

Objective To determine the levels of arsenic in food in Chongqing city,and to assess the levels of dietary arsenic exposure and the associated potential health risks in residents of Chongqing city.Methods By using the monitoring data on arsenic levels in food in Chongqing between 2018 and 2023 in combination with the local dietary survey data for Chongqing from the 2018 China Nutrition and Health Survey Program,and adopting the 2-dimensional Monte Carlo simulation,we made an estimate of the dietary arsenic exposure levels of Chongqing residents.The margin of exposure(MOE)method was applied to assess both non-carcinogenic risks(skin damage)and carcinogenic risks(lung cancer and urinary system cancers)associated with dietary intake of arsenic.Results Out of 4900 food samples,the detection rate of arsenic was 36.40％,with the average levels ranging from the median bound(MB)of 0.020 7 to the upper bound(UB)of 0.023 4 mg/kg.The highest average levels were found in rice and its products,with an MB of 0.0981 and a UB of 0.098 5 mg/kg.The daily average exposure to inorganic arsenic for residents of different ages,sexes,and places of residence was highest in individuals aged 3 to 6,with an MB of 1.046 μg/(kg·d)and a UB of 1.116 μg/(kg·d),and lowest among individuals aged 60 and older.Arsenic exposure was higher in males than that in females and higher in people living in rural areas compared to those in urban areas.In terms of non-carcinogenic risks,the MOE values for inorganic arsenic were always higher than 1 in various populations.As for carcinogenic risks,the MOE values were all less than 100 in various populations.Rice and its products were the main source of dietary arsenic exposure in Chongqing,accounting for 69.97％to 74.37％of the total exposure.Conclusion The non-carcinogenic risk caused by dietary arsenic exposure in Chongqing is relatively low,but there may be a certain level of carcinogenic risk.Continued attentions should be given to dietary arsenic exposure levels in young children.

Objective:To analyze the changing trends in maternal mortality ratios (MMRs) and the main cause-specific MMRs in China from 2010 to 2020, evaluate the association between MMRs and pregnancy healthcare and predict the MMRs for the next five years.Methods:Data on MMRs, the main cause-specific MMRs, and maternal healthcare in China from 2010 to 2020 were collected from China Health Statistical Yearbook. Estimated annual percent changes (EAPCs) were used to analyze the trends in MMRs and the main cause-specific MMRs in China. Average growth rate was used to describe the trend of perinatal healthcare indicators, and spearman rank correlation was used to analyze the correlation between MMRs and perinatal healthcare indicators. GM (1,1) model was established to predict the MMRs for the following five years. Results:(1) From 2010 to 2020, the EAPCs were－5.16%,－6.24%, and－4.28%, respectively, indicating downward trends in MMRs in the whole nation, urban and rural areas ( t=－0.98,－12.42 and－8.96, all P<0.001). (2) From 2010 to 2020, the main cause-specific MMRs in China from obstetric hemorrhage, hypertension during pregnancy, amniotic fluid embolism, and liver disease were all in downward trends ( t=－12.42,－5.44,－3.98 and－3.63, all P<0.001). Except for the MMR from hypertension during pregnancy in urban areas (average growth rate =0.51%), all main cause-specific MMRs in both urban and rural areas decreased significantly, especially the MMRs from hepatopathy in urban and rural areas (average growth rate=－10.40% and－13.96%). (3) The nation wide MMR was negatively correlated with maternal system management rate ( r s=－0.80, P=0.003), prenatal examination rate ( r s=－0.97, P<0.001), postpartum visit rate ( r s=－0.82, P=0.002) and hospital delivery rate ( r s=－0.98, P<0.001). Negative correlations were also found between the MMR and hospital delivery rate in both urban ( r s=－0.82, P=0.002) and rural areas ( r s=－0.95, P<0.001). (4) The GM (1, 1) models for forecasting MMRs in the whole nation, urban and rural areas were established with an accuracy of level 1. The MMR was predicted to show a downward trend in the following five years. The MMRs in China were 15.86/100 000 in 2021 and 15.13/100 000 in 2022 through prediction, similar to the 16.1/100 000 and 15.7/100 000 as announced by the government. Conclusions:The overall MMR in China shows a downward trend, and it dropped faster in urban areas than the rural areas. In addition, it is predicted that the MMR will continue to decline in the following five years, but the gap between urban and rural areas will remain.

Ginsenoside Rb1, the effective constituent of ginseng, has been demonstrated to play favorable roles in improving the immunity system. However, there is little study on the osteogenesis and angiogenesis effect of Ginsenoside Rb1. Moreover, how to establish a delivery system of Ginsenoside Rb1 and its repairment ability in bone defect remains elusive. In this study, the role of Ginsenoside Rb1 in cell viability, proliferation, apoptosis, osteogenic genes expression, ALP activity of rat BMSCs were evaluated firstly. Then, micro-nano HAp granules combined with silk were prepared to establish a delivery system of Ginsenoside Rb1, and the osteogenic and angiogenic effect of Ginsenoside Rb1 loaded on micro-nano HAp/silk in rat calvarial defect models were assessed by sequential fluorescence labeling, and histology analysis, respectively. It revealed that Ginsenoside Rb1 could maintain cell viability, significantly increased ALP activity, osteogenic and angiogenic genes expression. Meanwhile, micro-nano HAp granules combined with silk were fabricated smoothly and were a delivery carrier for Ginsenoside Rb1. Significantly, Ginsenoside Rb1 loaded on micro-nano HAp/silk could facilitate osteogenesis and angiogenesis. All the outcomes hint that Ginsenoside Rb1 could reinforce the osteogenesis differentiation and angiogenesis factor's expression of BMSCs. Moreover, micro-nano HAp combined with silk could act as a carrier for Ginsenoside Rb1 to repair bone defect.
