ObjectiveTo explore the role of flurochloridone (FLC) on osteogenic differentiation and the potential mechanism of inhibiting bone formation, and to provide new insights into bone health risks associated with FLC pesticide exposure. MethodsNeonatal rat skull differentiation primary osteoblast model was used to investigate the effects of 1, 10 and 100 μmol·L-1 FLC exposure on cell viability, osteogenic differentiation alkaline phosphatase (ALP) activity, and bone mineralization nodule formation, respectively. The potential mechanism underlying the inhibition of FLC on osteoblast differentiation was analyzed using osteogenic differentiation gene chip technique, and the expression of key genes and proteins in the pathway was validated using reverse transcription polymerase chain reaction (RT-PCR) and protein immunoblotting (Western blot) methods. ResultsExposure to FLC at a concentration of 100 μmol·L⁻¹ reduced cell proliferation, ALP activity, and the formation of mineralized nodules in primary osteoblasts. Gene chip analyses revealed that exposure to 10 μmol·L⁻¹ FLC induced 15 differentially expressed genes (DEGs). Among these, MMP9 and Tnf were up-regulated, while Nkx3⁃2, Tuft1, Bmp2, Col12a1, Pparg, Enam, Igf1, Bmp5, Bmp3, Calcr, Egf, Igfbp3, and Col14a1 were down-regulated. Results of protein-protein interaction analyses and gene ontology enrichment analyses indicated that FLC inhibited the BMP/SMAD pathway involved in osteogenic differentiation. FLC suppressed the protein expression of BMP2 and Osterix, as well as the expression of key genes critical for osteogenic differentiation and ossification, such as BMP2, Runx2, SMAD1, and SMAD5 in the BMP/SMAD pathway. ConclusionFLC affects osteogenic differentiation and bone formation potential by regulating the BMP/SMAD axis and the expression of osteogenic genes, suggesting its potential risk in bone metabolism.

To analyze the treatment strategy for a 78-year-old female patient with mismatch repair deficient (dMMR) gastric cancer who achieved long-term survival. After third-line chemotherapy failed, gene testing showed ARID1A p.Gln748fs, c.2733-1G>T variation, with PD-L1 TPS 30%, CPS 60%. The nivolumab was employed, and two weeks later, the best response was partial response (PR). During the fourth-line immunotherapy maintenance treatment, progression of left adrenal metastasis was observed. The expression of human epidermal growth factor receptor-2 (HER-2) was positive, and the antibody drug conjugate disitamab vedotin (RC48) was chosen for treatment. After 10 months of treatment with nivolumab combined with RC48, the best efficacy was assessed as stable disease (SD), with a progression free survival (PFS) of up to 12 months. Radiotherapy was employed, and immunotherapy was maintained, allowing the patient to achieve a PFS of 18 months again. During immunotherapy, a clinical pharmacist developed a personalized pharmaceutical care plan for this patient. At the last follow-up, this patient achieved 78 months of long-term survival.

Objective:To explore the effectiveness of rapid cycle deliberate practice (RCDP) in training newly hired nurses′comprehensive emergency competence and to provide references for enhancing their capabilities.Methods:A quasi-experimental study was conducted using purposeful sampling. From September to December 2022, newly hired nurses at Liaocheng Second People′s Hospital were selected as research subjects and randomly assigned to a controlor an observation group using random number table. The control group received traditional group drill training, while the observation group underwent RCDP training. The study compared pre- and post-training scores of emergency theory and skill assessments, scores on the Chinese version of the Perceived Cognitive Ability Scale in Emergency Situations (PCAS), and training satisfaction levels between the two groups.Results:Each group comprised 30 nurses. The control group consisted of 3 males and 27 females, with a mean age of (22.70 ± 1.09) years; the observation group included 2 males and 28 females, with a mean age of (22.93 ± 0.87) years. Post-training comprehensive emergency competence assessment scores was (89.19 ± 1.47) in the control group and (93.00 ± 1.41) in the observation group, with a statistically significant difference ( t = - 4.60, P<0.01). The scores and total scores of PCAS in the observation group were (34.23 ± 1.91), (12.70 ± 1.62), (10.03 ± 1.52) and (56.97 ± 3.09), respectively, which were higher than the (31.70 ± 2.42), (11.90 ± 1.16), (9.10 ± 1.42), and (52.47 ± 3.65) in the control group, the difference between the two groups were statistically significant ( t value were - 5.16 - - 2.20, all P<0.05). The total score of training satisfaction of nurses in the observation group was (41.93 ± 2.53) points, and the difference was statistically significant compared with the (33.80 ± 2.58) pointsin the control group ( t = - 12.33, P<0.01). Conclusions:The application of the RCDP method in training newly recruited nurses′comprehensive emergency competence effectively enhances their learning enthusiasm and initiative, thereby improving training outcomes.

Global public health is currently undergoing unprecedented and complex changes. The COVID-19 pandemic has exposed vulnerabilities and weaknesses of the global health system, urging nations globally to prioritize pandemic prevention and response strategies. Simultaneously, emerging infectious diseases such as mpox and avian influenza, as well as re-emerging infectious diseases including tuberculosis, AIDS, and viral hepatitis, continue to pose threats to global public health security. Moreover, the prevalence of chronic diseases remains significant, while concerns pertaining to environmental health and the well-being of children and adolescents are growing increasingly prominent. Addressing these challenges requires the formulation of effective public health policies, strengthened international cooperation, enhanced health education, improved public health literacy, and the establishment of a more resilient global public health system.

OBJECTIVES:
To investigate pharmacologically active components of Yiqi Zishen Formula (YZF) and their mechanisms for alleviating airway inflammation in mice with chronic obstructive pulmonary disease (COPD).
METHODS:
Ultra-high-performance liquid chromatography coupled with quadrupole-orbitrap mass spectrometry was employed to characterize the chemical components in YZF and YZF-medicated rat serum. A compound-disease target network was constructed based on serum components of YZF to screen the key pathways and targets using enrichment analysis. A mouse model of cigarette smoke-induced COPD was used to evaluate the anti-inflammatory effect of YZF and validate the expression of key proteins in network pharmacology-enriched pathways. Fifty male C57BL/6J mice were randomized equally into control group, COPD model group, high- and low-dose YZF treatment groups, and N-acetylcysteine treatment group. Pulmonary function of the mice was assessed using whole-body plethysmography, and lung histopathology, alveolar structure, and airway remodeling were analyzed using HE staining. The levels of IL-1β, IL-6, and TNF‑α in bronchoalveolar lavage fluid (BALF) were determined with ELISA, and pulmonary expressions of PI3K, Akt, phosphorylated Akt (p-Akt), p65, and phosphorylated p65 (p-p65) were detected using immunohistochemistry.
RESULTS:
We identified a total of 156 chemical components (including 26 flavonoids or flavonoid glycosides, 27 alkaloids, and 11 saponins) in YZF and 43 prototype components in medicated rat serum. Network pharmacology revealed 704 YZF-related targets and 1199 COPD-associated targets. Integrated analysis suggested that the anti-COPD effects of YZF were associated with the PI3K-Akt signaling pathway. In mouse models of COPD, YZF treatment significantly increased mean alveolar number and peak expiratory flow (P<0.05), reduced mean linear intercept, bronchial wall thickness, lung coefficient, and BALF cytokine levels, and suppressed the expressions of PI3K, Akt, p-Akt, p65, and p-p65 in the lung tissues.
CONCLUSIONS
YZF alleviates COPD symptoms and airway inflammation in mice possibly by inhibiting the PI3K/Akt/NF‑κB pathway through its multiple components that interact with multiple targets.

OBJECTIVE:
This study investigates the efficacy and mechanisms of Qingjie Fuzheng Granules (QFG) in inhibiting colitis-associated colorectal cancer (CAC) development via RNA sequencing (RNA-seq) and 16S ribosomal RNA (rRNA) correlation analysis.
METHODS:
CAC was induced in BALB/c mice using azoxymethane (AOM) and dextran sulfate sodium (DSS), and QFG was administered orally to the treatment group. The effects of QFG on CAC were evaluated using disease index, histology, and serum T-cell ratios. RNA-seq and 16S rRNA analysis assessed the transcriptome and microbiome change. Key pharmacodynamic pathways were identified by integrating these data and confirmed via Western blotting and immunofluorescence. The link between microbiota and CAC-related markers was explored using linear discriminant analysis effect size and Spearman correlation analysis.
RESULTS:
Long-term treatment with QFG prevented AOM/DSS-induced CAC formation, reduced levels of interleukin (IL)-1β, tumor necrosis factor-alpha (TNF-α), IL-6, and interferon γ (IFN-γ), and increased CD3+ and CD4+/CD8+ T cells ratio, without causing hepatic or renal toxicity. A 16S rRNA analysis revealed that QFG rebalanced the Firmicutes/Bacteroidetes ratio and mitigated AOM/DSS-induced microbiota disturbances. Transcriptomics and Western blotting analysis identified the nucleotide-binding oligomerization domain-containing protein 2 (NOD2)/nuclear factor kappa-B (NF-κB) pathway as key for QFG's treatment against CAC. Furthermore, QFG decreased the abundance of Bacilli, Bacillales, Staphylococcaceae, Staphylococcus, Lactobacillales, Aerococcus, Alloprevotella, and Akkermansia, while increasing Clostridiales, Lachnospiraceae, Lachnospiraceae_NK4A136_group, Ruminococcaceae, and Muribaculaceae, which were highly correlated with CAC-related markers or NOD2/NF-κB pathway.
CONCLUSION
By mapping the relationships between CAC, immune responses, microbiota, and key pathways, this study clarifies the mechanism of QFG in inhibiting CAC, highlighting its potential for clinical use as preventive therapy.
