ObjectiveThis paper aims to investigate the material basis of the anti-inflammatory efficacy and mechanism of action of Bushen Tongdu prescription （BSTDP）. MethodsThe chemical components of BSTDP and its blood-absorbed components in vivo were systematically identified by using ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry （UPLC-LIT-Orbitrap-MS）. Network pharmacology was employed to screen blood-absorbed bioactive components and potential targets of this formula. A protein-protein interaction （PPI） network of core targets was constructed to conduct enrichment analysis. Molecular docking was further utilized to verify the binding affinity between key components and targets. The inflammatory model was established and verified in vivo by using a transgenic zebrafish Tg （mpx： GFP）. At three days post-fertilization （3 dpf）， larvae of zebrafish were randomly assigned to blank group， model group， positive drug dexamethasone acetate group （75 μmol·L^-1）， and BSTDP groups with low， medium， and high doses （500， 1 000， and 2 000 mg·L^-1）. The distribution and quantity of neutrophils in the yolk sac region were observed under a fluorescence microscope. The mRNA expression levels of key genes in the toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor kappa-B （NF-κB） signaling pathway and inflammatory factors including interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α） were detected by Real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsA total of 120 chemical components were identified in BSTDP， among which 26 original components were confirmed by using serum pharmacochemical methods. A total of 227 common targets linking rheumatoid arthritis （RA） and the blood-absorbed components were screened by network pharmacology. It is suggested that pseudobrucine， vomicine， sinapine， rehmannioside， cinnamyl alcohol glycoside， and methylephedrine exert anti-inflammatory effects by acting on core targets including protein kinase B1 （Akt1）， signal transducer and activator of transcription 3 （STAT3）， tumor necrosis factor （TNF）， TLR4， mitogen-activated protein kinase 14 （MAPK14）， and phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit α （PIK3CA）， thereby modulating multiple signaling pathways such as TLR4 and NF-κB. In vivo verification in zebrafish demonstrates that the maximum tolerable concentration of Bushen Tongdu Formula is 2 000 mg·L^-1. Compared to those in the blank group， zebrafish in the model group showed a significantly higher number of neutrophils in the yolk sac region （P<0.01） and rising mRNA levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β （P<0.01）. Compared to that in the model group， the number of neutrophils was significantly reduced in BSTDP groups with medium and high doses， as well as the dexamethasone acetate group （P<0.05， P<0.01）. There was no statistically significant difference in the low dose group. The mRNA expression levels of TLR4， MyD88， NF-κB， TNF-α， IL-6， and IL-1β were significantly down-regulated （P<0.05， P<0.01）. ConclusionThis paper identifies the material basis of the efficacy of BSTDP， demonstrating that the formula can exert an anti-inflammatory effect through the TLR4/MyD88/NF-κB signaling pathway. The results provide scientific experimental evidence for its further clinical application.

Abstract To clarify the service targets, service contents, and safeguard mechanisms of the basic public service program for student vision health management, the study grounded in the current status of child and adolescent myopia prevention and control in China and integrated with the practical experience and innovative practices of Wuhan National Demonstration Area for Student Vision Health Management, takes education as the main thread and schools as the base, consolidating resources from multiple stakeholders including education administrative departments, schools, families, and professional technical service institutions. Centering on four core components—vision health education, monitoring and record keeping, risk prevention and control, and dynamic management, the study constructs a multi tiered basic public service system for vision health management of primary and secondary school students. It further proposes the use of an intelligent management platform and a "three tier color coded early warning" mechanism (red, yellow, blue) to prevent and control student myopia at the source, providing schools with replicable and operable implementation pathways to enhance the level of student vision health management.

Objective To explore the effects of eugenol combined with traditional Chinese medicine Wuxing music(EUG+MUSIC)on skin inflammation,behavioral characteristics,hormone and neurotransmitter levels,and the intestinal microbiota in a mouse model of 2,4-dinitrofluorobenzene(DNFB)-induced atopic dermatitis(AD).Methods A mouse model of AD was established by induction with DNFB for 21 consecutive days;throughout the study,changes in dorsal skin lesions and scratching behavior were recorded in mice and changes in dorsal skin lesions and pruritus were recorded.Mice underwent open-field,elevated 0 maze,tail-suspension,and forced-swimming tests on days 19 and 20.The mice were then sacrificed on day 21 and the organ index was calculated.Serum levels of immunoglobulin E,interleukin(IL)-4,and IL-10 were determined by enzyme-linked immunosorbent assay.Pathological changes in back-skin sections were detected by hematoxylin-eosin(HE)and toluidine blue staining,and brain levels of corticosterone,dopamine,and serotonin were measured.The composition of the intestinal microbiota was analyzed by 16S rRNA gene sequencing.Results The skin lesion score and skin inflammatory cell infiltration were significantly reduced in the EUG+MUSIC group.Regarding the behavioral tests,mice in the EUG+MUSIC group showed more active locomotion,an increased desire to explore unfamiliar environments,and increased struggling time in stressful situations.Brain levels of serotonin,dopamine,and corticosterone were also increased in the EUG+MUSIC group.16S rRNA gene sequencing showed that DNFB affected the diversity of the intestinal microbiota in AD mice,while EUG+MUSIC treatment remodeled the gut microbial composition,including increasing the relative abundance of gut microbes such as Ligilactobacillus and Lachnospiraceae and decreasing Parabacteroides and Bacteroides spp.Spearman's analysis showed significant correlations among altered gut microbiota,AD-associated skin manifestations,and anxiety-and depressive-like behaviors arising from comorbidities.Conclusions Eugenol combined with traditional Chinese medicine five-elements music therapy may have a positive effect on comorbid anxiety-and depression-like behaviors by regulating the intestinal microbiota and improving the behavioral performance in mice with AD,thus providing new ideas and method for improving AD and its associated anxiety-and depressive behaviors.

Objective To develop models for predicting response to chemotherapy combined with immunotherapy in patients with esophageal squamous carcinoma with various machine learning algorithms,and then select the optimal model.Methods A retrospective study was performed for 174 patients with esophageal squamous cell carcinoma undergoing chemotherapy combined with immunotherapy admitted in Department of Thoracic Surgery of the First Affiliated Hospital of Army Medical University from January 2022 to December 2023.The CT scans and clinical information were collected before treatment.They were randomly divided into a training set(n=122)and a testing set(n=52)in a ratio of 7∶3.CT radiomic features were extracted and selected,and then 5 machine-learning algorithms were employed to establish the prediction models,including radiomics model and clinical-radiomics model.Five-fold cross-validation was conducted on the training set,and the performance of the prediction models was evaluated on the testing set using receiver operating characteristic(ROC)curve and the F1 score.The best-performing model was further explained using local interpretable model-agnostic explanations(LIME)algorithm.Results Among the 174 patients,115(66.1%)achieved clinical remission.From the clinical information and CT images,1 clinical features and 10 radiomic features were identified.The area under of ROC curve(AUC)for the radiomics and clinical-radiomics models was 0.750(95%CI:0.616～0.883),and 0.766(95%CI:0.637～0.895),respectively.The F1 score of the optimal clinical-radiomics model was 0.829.LIME algorithm indicated that this best model demonstrated reliability in predicting individual samples.Conclusion The clinical-radiomics prediction model based on machine learning algorithm performs well,and can provide a reference for doctors'clinical decision-making by predicting the response to chemotherapy combined with immunotherapy in patients with esophageal squamous cell carcinoma.

Objective:To investigate the effect of short-term intensive insulin pump therapy on blood glucose control and renal function in type 2 diabetes mellitus (T2DM) patients with diabetic kidney disease (DKD).Methods:The clinical data of 360 T2DM patients with DKD in Shanxi Bethune Hospital from January 2022 to October 2024 were retrospectively analyzed. These patients were divided into an observation group ( n=192; treated with continuous subcutaneous insulin infusion) and a control group ( n=168; treated with conventional hypoglycemic therapy) according to the different treatment modalities; subsequently, 103 pairs of patients entered final analysis by using the propensity score matching method. The differences in glycemic control and improvement of renal function were compared between these two groups. Results:Before the treatment, the blood glucose-, blood glucose fluctuation-, and kidney function-related indicators showed no significant differences between these two groups (all P>0.05). After the treatment, fasting blood glucose, two-hour postprandial blood glucose, and average blood glucose significantly decreased in both groups and were significantly lower in the observation group than in the control group (all P<0.05). In addition, the amplitude of postprandial blood glucose fluctuation, standard deviation of intraday multi-point blood glucose, and difference between the maximum and minimum intraday blood glucose values significantly declined after treatment and were also significantly lower in the observation group than in the control group (all P<0.05). The observation group had a significantly higher total glycemic control rate and a significantly lowr incidence of hypoglycemia (both P<0.05). Finally, the 24-hour urine protein level, serum creatinine level, and urine albumin/creatinine ratio of the observation group significantly dropped after the treatment, and these results were significantly lower than those in the observation group (all P<0.05). Conclusions:Intensive insulin pump therapy benefits T2DM patients with DKD by improving glycemic control and enhancing renal function.

Objective:To investigate the current situation of professional identity and work readiness of newly graduated nursing students, explore the correlation between professional identity and work readiness, and provide a reference for promoting their professional development.Methods:From May to September 2023, a total of 584 newly graduated nursing students who were about to participate in standardized residency training were selected from 7 tertiary hospitals in the main urban area of Chongqing using cluster sampling. The general information questionnaire, Nurse Professional Identity Scale, and Nurse Work Readiness Scale were used for data collection. SPSS 23.0 was used to analyze the current situation of professional identity and work readiness among the participants.Results:A total of 536 valid questionnaires were collected, with an effective recovery rate of 91.78%. The professional identity scores of newly graduated nursing students ranged from 23 to 83 (66.94±11.38) points and the work readiness scores ranged from 115 to 370 (271.47±44.54) points, which were positively correlated ( r=0.673, P<0.001). Hierarchical regression analysis showed that professional identity entered into the influencing factor model of work readiness ( F=38.350, P<0.001), which could independently explain 50.80% of the variation in work readiness. Conclusions:The professional identity and work readiness of newly graduated nursing students are at moderate levels. Nursing educators and hospital nursing managers should pay attention to the assessment of their professional identity and work readiness, adopt scientific and effective methods to improve their work readiness, ensure a smooth professional transition, and promote their career development.

Objective To quantitatively measure the density of hydroxyapatite(HAP)(water)within lumbar vertebral bodies using the gemstone spectral imaging(GSI)material decomposition technique and to compare and analyze the clinical significance of density variations of HAP(water)in different regions of L1-L3 vertebral bodies.Methods A total of 242 patients who underwent lumbar quantitative computed tomography(QCT)scans via utilizing the GSI technique were selected.Following the scans,the HAP(water)density values in four regions(anterosuperior,posterosuperior,anteroinferior,and posteroinferior)of each L1-L3 vertebral bodies were quantitatively measured using the material decomposition technique.Based on the QCT results,all cases were divided into three groups of normal bone mineral density,osteopenia,and osteoporosis.The distributions of HAP(water)density values in the four regions within each vertebral body were compared and analyzed among the groups.Results In all three groups of patients,the highest HAP(water)density values in the L1-L3 vertebral bodies were all located in the posteroinferior region,followed by the posterosuperior region.In the normal bone mineral density group,the lowest HAP(water)density values was found in the anterosuperior region of the L1 vertebral body.In the osteopenia and osteoporosis groups,the lowest HAP(water)density values was found in the anteroinferior region of the L1-L3 vertebral bodies.Conclusion Significant differences in HAP(water)density are present across different regions within lumbar vertebral bodies,which may be related to the development of vertebral osteoporosis and the location of fractures.
