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 investigate the association between prenatal environmental factors and attention defi-cit hyperactivity disorder(ADHD)and its symptom severity in children.Methods:Based on the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)diagnosis criteria,1 156 children with ADHD and 289 normal control children were included in this study.ADHD diagnoses were established using the Clinical Diag-nostic Interview Scale,core symptoms were assessed with the ADHD Rating Scale,and information on prenatal ex-posures were collected via self-developed questionnaires.Results:Maternal stress during pregnancy was associated with increased risk factor of ADHD in children(OR=1.22,P＜0.01).Among children with ADHD,preconception paternal alcohol consumption was positively associated with hyperactivity/impulsivity symptoms(β=0.08,P＜0.05),and maternal smoking during pregnancy was positively associated with total symptoms(β=0.07-0.09,P＜0.05).Conclusion:Maternal stress during pregnancy may increase the risk factor of ADHD in children.Both pre-conception paternal alcohol consumption and maternal smoking during pregnancy may be associated with increased ADHD symptom severity in children.

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.

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 evaluate the relationship between the mechanism of buprenorphine in attenuating neuroinflammation in microglia and the MAM domain-containing glycosylphosphatidylinositol anchor gene 1 ( MDGA1). Methods:The human microglial cell line HMC-3 was cultured in vitro and divided into 4 groups ( n=6 each) using a table of random numbers: control group (Con group), lipopolysaccharide(LPS)group, buprenorphine + LPS group (Bup+ LPS group) and buprenorphine + LPS + MDGA1 knockdown group (Bup+ LPS+ shMDGA1 group). LPS group was incubated with LPS at a final concentration of 1 μg/ml for 4 h. Bup+ LPS group was incubated with buprenorphine at a final concentration of 100 ng/ml for 1 h, followed by incubation with LPS at a final concentration of 1 μg/ml for 4 h. Bup+ LPS+ shMDGA1 group was transfected with MDGA1-specific shorthairpin RNA for knockdown, and the remaining treatment was similar to those previously described in Bup+ LPS group. The expression of MDGA1 in microglia was detected using real-time quantitative polymerase chain reaction, and the concentrations of interleukin (IL)-6, IL-1β, tumor necrosis factor-α (TNF-α), and inducible nitric oxide synthase (iNOS) in the supernatant were measured using enzyme-linked immunosorbent assay. Results:Compared with Con group, the concentrations of IL-6, IL-1β, TNF-α and iNOS in the supernatant were significantly increased, and the expression of MDGA1 in microglia was down-regulated in LPS group ( P<0.05). Compared with LPS group, the concentrations of IL-6, IL-1β, TNF-α and iNOS in the supernatant were significantly decreased, and the expression of MDGA1 in microglia was up-regulated in Bup+ LPS group ( P<0.05). Compared with Bup+ LPS group, the concentrations of IL-6, IL-1β, TNF-α and iNOS in the supernatant were significantly increased, and the expression of MDGA1 in microglia was down-regulated in Bup+ LPS+ sh MDGA1 group ( P<0.05). Conclusions:The mechanism by which buprenorphine alleviates neuroinflammation in microglia may be related to the up-regulation of the expression of MDGA1.

Objective To evaluate the clinical value of multiplex polymerase chain reaction(mPCR),serum IgM and urinary Legionella pneumophila antigen detection in the diagnosis and treatment of adult community-acquired pneumonia(CAP)for Mycoplasma pneumoniae(MP),Chlamydia pneumoniae(CP)and Legionella pneumophila(LP).Methods A total of 275 inpatients diagnosed with CAP from October 2018 to January 2022 in Beijing Tongren Hospital were selected as the study objects.275 lower respiratory tract samples,195 serum samples and 50 urine samples were collected for sanger sequencing,mPCR,serum IgM and urinary LP antigen test,respectively.With the result of sanger sequencing as the reference standard,the clinical application value of the three detection methods was evaluated.Results The infection rate of atypical pathogens in adult patients with CAP was 26.5%(73/275).The infection rates of MP,CP and LP were 21.8%(60/275),2.2%(6/275)and 2.5%(7/275),respectively.The sensitivity of mPCR,serum IgM and urinary LP antigen test were 100%(72/72),31.0%(18/58),100%(7/7),and the specificity were 99.5%(202/203),76.6%(105/137),100%(43/43),respectively.The sensitivity of serum IgM was significantly decreased in patients with time≤7 days compared to patients with time>7 days from onset to sampling(41.9%vs 14.3%),the difference was statistically significant(χ2=5.483,P<0.05).The proportion of false negative for serum IgM was the highest in 25～<41 years old(57.5%),and the difference was statistically significant among all age groups(χ2=25.069,P<0.001).The proportion of false positive for serum IgM was the highest among 41～<66 years old(37.5%),and there was no significant difference among all age groups(χ2=6.404,P=0.171).The IgM cross-reactivity rate of the three atypical pathogens was 33.3%(13/39).Conclusion Serum IgM is not suitable for the diagnosis of atypical pathogen infection in adults alone,mPCR and urinary LP antigen test have obvious advantages in the early diagnosis of CAP in adults.

Objective·To investigate the effects and molecular mechanisms of phosphatidylethanolamine(PE)on macrophage senescence and its senescence-associated secretory phenotype(SASP),as well as its pathophysiological role in liver injury.Methods·A macrophage senescence model was established using doxorubicin(DOX),followed by PE treatment.A mouse liver injury model was generated via intraperitoneal co-administration of PE and lipopolysaccharide(LPS)to investigate the effects of PE on liver injury.Senescence markers and SASP factors,including senescence-associated β-galactosidase(SA-β-gal),cell cycle inhibitor p21,tumor necrosis factor-α(TNF-α),and interleukin-6(IL-6),were evaluated using SA-β-gal staining,quantitative real-time PCR,and Western blotting.RNA sequencing(RNA-seq)was performed,followed by Gene Ontology(GO)cellular component enrichment analysis,Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis,Gene Set Variation Analysis(GSVA),and Gene Set Enrichment Analysis(GSEA),to explore the molecular mechanisms and signaling pathways by which PE promotes macrophage senescence.The expression of endoplasmic reticulum(ER)stress-related proteins,including inositol-requiring enzyme 1 α(IRE1α),spliced X-box binding protein 1(XBP1s),activating transcription factor 6(ATF6),ATF4,and C/EBP homologous protein(CHOP),was analyzed through in vivo and in vitro experiments.Results·PE significantly promoted the expression of senescence markers SA-β-gal,p21,p16 and SASP factors.RNA-seq analysis revealed that ER stress was involved in PE-induced promotion of SASP.Further experiments demonstrated that PE activated the ER stress signaling pathway,promoting macrophage senescence and the expression of SASP factors.In vivo experiments further confirmed that PE exacerbated LPS-induced liver injury in mice through ER stress.Conclusion·PE promotes macrophage senescence and the expression of SASP factors by activating ER stress signaling pathway,thereby aggravating LPS-induced liver injury.

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.
