Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Objective To observe the effect of Danshen injection (DSI) on pulmonary fibrosis in silicosis mice, and to analyze the differential metabolic pathway on pulmonary fibrosis in silicosis using DSI by urine metabolomics. Methods The specific pathogen free C57BL/6J mice were randomly divided into control group, silicosis model group, DSI prevention group and DSI treatment group. The mice in the last three groups were given 1 mL silica suspension with a mass concentration of 50 g/L by the one-time non-exposed tracheal method, and the mice in the control group were not given any treatment. Subsequently, mice in the DSI prevention group and the DSI treatment group were given intraperitoneal injection of DSI with a dose of 5 mL/kg body weight from 24 hours after exposure to dust and from the 29th day after exposure to dust, respectively, once per day until the 56th day after exposure. Mice in the other two groups were not treated. After DSI intervention, the lung histopathological changes of mice in all groups were evaluated. The components of mouse urine metabolites were analyzed using ultra-high performance liquid chromatography-quadrupole-time-of-fight mass spectrometry method. Human Metabolome Database was used to screen the potential differential metabolites (DMs). The related metabolic pathways were analyzed using MetaboAnanlyst 5.0 Web analytics platform. Results The result of hematoxylin-eosin staining and Van Gieson staining of mouse lung tissues showed that the pulmonary alveolar structure destroyed, typical fibrotic nodules appeared, collagen fiber deposition increased, and clumpy accumulation in the silicosis model group, compared with the control group. Compared with the silicosis model group, the degree of pulmonary alveolar inflammation and fibrosis in the lung tissues of mice in the DSI prevention group was obviously reduced to close to the control group, while pulmonary alveolar inflammation and fibrosis in the lung tissues of mice in the DSI treatment group were also reduced, although the outcome was not as good as that in the DSI prevention group. The result of urine metabolomics analysis identified four DMs in the model group and control group, seven DMs were identified in the DSI prevention group and silicosis model group, seven DMs were identified in the DSI treatment group and silicosis model group. A total of three DMs pathways related to pulmonary fibrosis in silicosis model group and the protective effect of DSI prevention group were identified, including D-arginine and D-ornithine metabolism, folic acid biosynthesis and metabolism, pantothenate and succinyl coenzyme A biosynthesis pathways (all P<0.01). Conclusion DSI treatment in any time point can interfere the process of pulmonary fibrosis in the silicosis mice, while the interference is more effective in the DSI group treated right after dust-exposure. DSI interferes with the urinary metabolism pathway of silicosis mice, and the D-arginine and D-ornithine metabolism, folic acid biosynthesis and metabolism, pantothenate and succinyl coenzyme A biosynthesis pathways may participate in the inhibiting process of early pulmonary fibrosis in silicosis mice by DSI.

Background:Intestinal microbiota dysbiosis and impaired intestinal barrier,leading to bacterial translocation,are involved in acute pancreatitis(AP)exacerbation.Antimicrobial peptides participate in the regulation of intestinal microbiota,yet their changes and roles in the course of AP are unclear.Aims:To investigate the dynamic changes and significance of antimicrobial peptides in the ileum and pancreas among three classical AP models.Methods:Three AP mouse models were established by using cathelicidin plus lipopolysaccharide(CAE+LPS),sodium taurocholate(N-Tau)and L-arginine(L-Arg),respectively.The pathological changes of pancreatic and ileal tissues were observed and scored.Real-time PCR was applied to detect the expression levels of the proinflammatory cytokines,and antimicrobial peptides including lysozyme(LZM),secretory phospholipase A2(sPLA2),angiogenin 4(Ang4),regenerating islet-derived protein 3(REG3)family,β-defensin family,cathelicidin-related antimicrobial peptide(CRAMP),and glycoprotein 2(GP2)in ileum and/or pancreas.The association between expressions of antimicrobial peptides and the injuries of pancreas and ileum was analyzed.Results:Pancreatic and ileal injuries could be observed in all three AP models in different time points with various degrees.The pathological scores of the CAE+LPS and N-Tau models reached the highest level and then declined from 0-72 h,while those of L-Arg model progressively increased within 72 hours.Compared with the corresponding controls,the mRNA levels of LZM,sPLA2,and Ang4 in ileal tissue,and the mRNA levels of CRAMP,GP2,and β-defensins in pancreatic tissue,were generally downregulated in all three AP models(all P<0.05).CAE+LPS and N-Tau models showed a trend of initial decrease followed by partial recovery,while L-Arg model exhibited a gradual downregulation trend.The mRNA levels of REG3β and REG3γ in ileum upregulated and reached the peak at 48 h or 24 h and downregulated significantly at 72 h in all three AP models(all P<0.05);while in pancreatic tissue,both REG3β and REG3γ were generally upregulated in all three AP models(all P<0.05),but fell back in CAE+LPS and N-Tau models at 72 h.The mRNA levels of ileal β-defensins upregulated significantly in the early stage of the disease(12 h)in all three AP models(all P<0.05),and then gradually decreased.Spearman correlation coefficient analysis showed that the expressions of ileal LZM,sPLA2,and Ang4,as well as the pancreatic CRAMP,GP2,and β-defensins,were significantly negatively correlated with the pancreatic and ileal pathological scores in all three AP models(all P<0.05);but the expression of REG3β in the pancreas was significantly positively correlated with the pancreatic and ileal pathological scores(all P<0.05).Conclusions:The expressions of LZM,sPLA2,and Ang4 in the ileum,as well as the expressions of CRAMP,GP2,β-defensin family,and REG3β in the pancreas of the three classical AP models,dynamically changed with the severity of the disease.Ileal and pancreatic antimicrobial peptides may affect the injuries of pancreas and intestine during AP by regulating intestinal microbiota.

This study aims to investigate the effect of salvianolic acid B (Sal B), the active ingredient of Salvia miltiorrhiza, on H9C2 cardiomyocytes injured by oxygen and glucose deprivation/reperfusion (OGD/R) through regulating mitochondrial fission and fusion. The process of myocardial ischemia-reperfusion injury was simulated by establishing OGD/R model. The cell proliferation and cytotoxicity detection kit (cell counting kit-8, CCK-8) was used to detect cell viability; the kit method was used to detect intracellular reactive oxygen species (ROS), total glutathione (t-GSH), nitric oxide (NO) content, protein expression levels of mitochondrial fission and fusion, apoptosis-related detection by Western blot. Mitochondrial permeability transition pore (MPTP) detection kit and Hoechst 33342 fluorescence was used to observe the opening level of MPTP, and molecular docking technology was used to determine the molecular target of Sal B. The results showed that relative to control group, OGD/R injury reduced cell viability, increased the content of ROS, decreased the content of t-GSH and NO. Furthermore, OGD/R injury increased the protein expression levels of dynamin-related protein 1 (Drp1), mitofusions 2 (Mfn2), Bcl-2 associated X protein (Bax) and cysteinyl aspartate specific proteinase 3 (caspase 3), and decreased the protein expression levels of Mfn1, increased MPTP opening level. Compared with the OGD/R group, it was observed that Sal B had a protective effect at concentrations ranging from 6.25 to 100 μmol·L^-1. Sal B decreased the content of ROS, increased the content of t-GSH and NO, and Western blot showed that Sal B decreased the protein expression levels of Drp1, Mfn2, Bax and caspase 3, increased the protein expression level of Mfn1, and decreased the opening level of MPTP. In summary, Sal B may inhibit the opening of MPTP, reduce cell apoptosis and reduce OGD/R damage in H9C2 cells by regulating the balance of oxidation and anti-oxidation, mitochondrial fission and fusion, thereby providing a scientific basis for the use of Sal B in the treatment of myocardial ischemia reperfusion injury.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.
