Liver injury due to acetaminophen overdose is one of the main causes of acute liver failure, with a complex pathogenesis. In this process, liver sinusoidal endothelial cell (LSEC) injury is a key early event jointly mediated by factors such as oxidative stress, cell apoptosis, and imbalance between fibrinolysis and coagulation. Subsequent LSEC dysfunction further induces sinusoidal microcirculatory disturbances, amplifies the inflammatory response, impairs the regeneration and repair abilities of the liver, and finally causes hepatocyte necrosis. This article systematically elaborates on the critical role and molecular mechanism of LSEC in acetaminophen-induced liver injury, in order to provide a theoretical basis for novel therapeutic strategies and research directions.

OBJECTIVES:
This study aimed to explore the clinical efficacy of severe early childhood caries (SECC) treatment combined with local anesthesia under general anesthesia.
METHODS:
A total of 108 children under 6 years old who underwent SECC dental treatment under general anesthesia at the Department of Pediatric Dentistry, Third Affiliated Hospital of Air Force Medical University from March to December 2023 were selected as the study subjects, with American Society of Anesthesiologists (ASA) classification of classⅠor Ⅱ. The study subjects were divided into a control group (n=54) and an experimental group (n=54) by retrieving intraoperative cases and postoperative follow-up records. The control group was given general anesthesia through inhalation combined with nasotracheal intubation, whereas the experimental group was given local anesthesia with 2% lidocaine on each treated tooth on the basis of general anesthesia. The basic information, preoperative anesthesia depth, hemodynamic changes during different surgical procedures, postoperative pain, and adverse reactions in the two groups were recorded and analyzed.
RESULTS:
No statistically significant difference was found in the basic information and preoperative anesthesia depth between the two groups (P>0.05). Among the three procedures (pulpotomy, root canal treatment, and tooth extraction), the three observed indicators in the experimental group were significantly lower than those in the control group (P<0.05). The proportion of patients in the experimental group who needed to take analgesic measures in accordance with the modified facial pain scale (FPS-R) score was significantly lower than that in the control group at postoperative wakefulness and 2 h after surgery (P<0.05). Meanwhile, no statistically significant difference was observed between the groups at 24 h after surgery (P>0.05). The proportion of patients in the experimental group who needed to take analgesic measures on the basis of the parent posto-perative pain measurement (PPPM) score was significantly lower than that in the control group when they were awake after surgery (P<0.05). No statistically significant difference was found between the groups at 2 and 24 h after surgery (P>0.05). Moreover, no statistically significant difference was observed in the incidence of adverse reactions between the two groups at 24 h after surgery (P>0.05).
CONCLUSIONS
The combination of local anesthesia during SECC dental treatment under general anesthesia results in minimal changes in intraoperative hemodynamics and mild postoperative pain response, hence worthy of clinical promotion.

Diabetic nephropathy(DN)is a significant causative factor of end-stage renal disease globally,and its pathogenesis involves dysregulation of multiple cellular and hormonal pathways.Podocytes play crucial roles in the process of DN,with the extent of podocyte injury closely associated with key pathological manifestations of renal damage,such as proteinuria,glomerular filtration rate,and glomerulosclerosis.However,due to the complexity and interplay of mechanisms contributing to podocyte injury,such as oxidative stress,abnormal lipid metabolism,and mitochondrial damage,the precise mechanisms underlying podocyte injury remain incompletely understood.This review integrated the latest research findings from both domestic and international studies on the core mechanisms of podocyte injury in DN.Furthermore,this article summarized the implications of these mechanisms for DN treatment,particularly focusing on potential therapeutic targets and the development of related pharmacological interventions derived from targeting podocyte injury pathways,so as to provide a theoretical foundation for the development of clinical therapeutic strategies for DN.

Health communication aims to improve public health attitudes and behaviors by propagating health information. It plays an important role in promoting public health literacy and "Healthy China Initiative". The basic theories of health communication include "7 W" and Theory of Planned Behavior. Clinicians with profound medical expertise and a wealth of clinical practice play key roles in the communication, and they hold an unparalleled advantage in health communication by delivering authoritative and trustworthy information to the public. The capacity of health communication among clinicians in the nation is determined by various factors including professional characteristics, policy support, dissemination platforms and pathways, time and effort. Meanwhile, some problems in the research on the health communication capacity of clinicians remain, such as lack of well-established motivation systems, limited dissemination pathways, and imperfect evaluation frameworks. In some regions of China, health communication performance has been considered as part of the professional title evaluation for clinical physicians. Medical institutions and universities have also initiated relevant training and practice programs. It is crucial to improve evaluation frameworks, strengthen training pathways and effectiveness assessment, promote interdisciplinary integration, and enhance the role of clinicians in health communication in the future.

Objective To compare the efficacy and safety of defocus incorporated soft contact lenses(DISC)and orthokeratology(Ortho-K)for myopia control in children aged 8~15 years,and to further investigate the influence of dif-ferent baseline age and spherical equivalent(SE)on the treatment effect.Methods A retrospective cohort study was conducted,involving 197 myopic children(197 eyes)aged 8~15 years who were fitted with contact lenses at the Depart-ment of Ophthalmology,Xi'an People's Hospital(Xi'an Fourth Hospital)from May to September 2023.They were divid-ed into the DISC group(97 cases)and the Ortho-K group(100 cases).After 12 months of continuous follow-up,the chan-ges in axial length(AL)at 3,6,and 12 months after lens wear were compared between the two groups.Subgroup analysis was then performed:participants were divided into a younger subgroup(8~10 years)and an older subgroup(11~15 years)based on pre-wear age,and into a low myopia subgroup(-1.00~-3.00 D)and a moderate myopia subgroup(-3.25~-6.00 D)based on pre-wear SE.The AL changes at 3,6,and 12 months after wearing DISC or Ortho-K were com-pared between groups within these subgroups.Meanwhile,the incidence of conjunctivitis,incidence of corneal staining,corneal endothelial cell density,and corneal thickness were compared between the two groups at 12 months after lens wear.Results Inter-group comparisons showed:The change in AL in the DISC group at 3 months after lens wear was significantly lower than that in the Ortho-K group,and the difference was statistically significant(P<0.05);at 6 and 12 months after lens wear,the differences in AL change between the two groups were not statistically significant(both P>0.05).Subgroup analysis by age and SE showed:In the younger subgroup and the low myopia subgroup,the AL change in the DISC group at 3 months after lens wear was significantly lower than that in the Ortho-K group,and the differences were statistically significant(both P<0.05),but these differences disappeared at 6 and 12 months after lens wear(all P>0.05);in the older subgroup and the moderate myopia subgroup,the differences in AL change between the two groups at 3,6,and 12 months after lens wear were not statistically significant(all P>0.05).At 12 months after lens wear,there were no statistically significant differences in the incidence of conjunctivitis,incidence of corneal staining,corneal endothe-lial cell density,or corneal thickness between the DISC and Ortho-K groups(all P>0.05).Conclusion DISC demon-strates superior myopia control efficacy in the short term(3 months)for younger children and those with low myopia,but its medium-term(6 months)and long-term(12 months)efficacy converges with that of Ortho-K.Furthermore,the long-term safety of DISC is not significantly different from that of Ortho-K.

Objective:To screen bile acid-related characteristic genes in IgA nephropathy (IgAN) based on the feature gene selection algorithm in the machine learning method, aiming to exploring the molecular biological mechanisms and biomarkers of IgAN.Methods:The gene expression data and sample grouping information of GSE93798, GSE116626 and GSE35487 were downloaded from the Gene Expression Omnibus (GEO). Bile acid-related gene sequences were obtained from the Molecular Signatures Database (MSigDB). R language was used to identify differentially expressed genes between IgAN samples and healthy control samples. Candidate genes were obtained by intersecting differentially expressed genes and bile acid-related genes. The least absolute shrinkage and selection operator (LASSO) algorithm in machine learning was used to screen the feature genes in the candidate genes as biomarkers, and the feature genes in the training set and validation set were analyzed by the rate of change index. Receiver operating characteristic curve (ROC) method was used to evaluate the diagnostic value of identified bile acid related characteristic genes for IgAN. Gene set enrichment analysis (GSEA) was used to analyze the Spearman correlation between the characteristic genes and all other genes and their related metabolic pathways. The expression of disease-characteristic genes in the kidney tissues of IgAN rats was validated by real-time PCR.Results:Gene expression information from kidney tissue samples of 20 IgAN cases and 22 healthy controls were obtained from GEO database. A total of 204 bile acid-related genes including 24 pathways were obtained from MSigDB. The results of gene differential expression analysis showed that 333 genes in the kidney tissues of IgAN patients were differentially expressed compared with those of healthy controls, including 102 up-regulated genes and 231 down-regulated genes, among which 12 differentially expressed genes were related to bile acid genes, as follows: NR1H4,SLC23A1, ALDH8A1, FABP1, ALB, SLC27A2, DIO1, CYP8B1, BBOX1, PIPOX, AKR1C1 and SLC10A2. Five characteristic genes ( NR1H4, SLC23A1, FABP1, ALB and AKR1C1) were screened by LASSO regression algorithm.ROC analysis results showed that in GSE93798 cohort genes, the AUC of NR1H4, SLC23A1, FABP1 and ALB genes with differential expression was >0.95 respectively in diagnosing IgAN, and that of AKR1C1 genes with differential expression was >0.85 in diagnosing IgAN. The gene expression data of SLC23A1 in GSE35487 cohort was missing. ROC analysis results of other four genes showed that the AUC of differential expression of ALB gene for IgAN was >0.95 respectively, that of NR1H4 gene was >0.70, and that of both FABP1 and AKR1C1 gene was >0.60. In the GSE116626 cohort genes, the AUC of five disease characteristic genes ( NR1H4, SLC23A1, FABP1, ALB, AKR1C1) for diagnosing IgAN was >0.60, respectively. These results suggested that 5 characteristic genes have certain distinguishing ability between IgAN group and control group. GSEA results were displayed that the characteristic genes were related to butyric acid metabolism, propionic acid metabolism, arginine and proline metabolism, valine leucine and isoleucine degradation, fatty acid metabolism, etc. These results suggested that five characteristic genes might be related to IgAN through the above metabolic mechanisms. The verification results of five bile acid characteristic genes in the rat model of IgAN in the kidney tissue showed that the expressions of four genes, NR1H4, SLC23A1, FABP1 and ALB, were higher than those of the control group, and there was no statistical significance in the expression of AKR1C1 gene between the two groups. Conclusions:The expression of bile acid-related characteristic genes is abnormal in the kidney tissue of IgAN patients. Four bile acid-related differentially expressed genes, NR1H4, SLC23A1, FABP1 and ALB, are expected to be biomarkers for non-invasive diagnosis and therapeutic targets .

Objective:To establish a framework of entrustable professional activity indicators for non-anesthesiology residents during rotation in the Department of Anesthesiology, standardize the training process, and provide an effective evaluation method.Methods:Based on literature review and discussions, a preliminary expert consultation questionnaire was developed. From July to November 2024, a modified Delphi method was adopted and relevant experts were invited to assess the importance, validity, and feasibility of each indicator using a 5-point Likert scale. The results were used to screen and refine the entrustable professional activity indicators for non-anesthesiology residents during rotation in the Department of Anesthesiology.Results:In the two rounds of expert consultation, the valid questionnaire return rate reached 100.00%, with an expert judgment basis coefficient of 0.73 and a familiarity coefficient of 0.90. Based on expert feedback, the final framework retained 3 first-level indicators and 12 second-level indicators. Modifications included renaming "Anesthesia Management" to "Anesthetic Drug Management", swapping the order of "Intraoperative Emergency Management" and "Airway Management", and removing the indicator "Resuscitation Assessment".Conclusions:This study preliminarily developed a framework of entrustable professional activity indicators for non-anesthesiology residents during rotation in the Department of Anesthesiology. The framework provides a simple and practical competency evaluation method for standardized training, which can enhance training quality and effectiveness.
