ObjectiveTo explore the effects of Yimei Baijiang formula （YMBJF） on colitis-associated colorectal cancer （CAC） and the nuclear factor kappaB （NF-κB） signaling pathway in mice. MethodsSixty male Balb/c mice of 4-6 weeks old were randomized into 6 groups： Normal， model， capecitabine （0.83 g·kg^-1）， and low-， medium-， and high-dose （4.63， 9.25， 18.50 g·kg^-1， respectively） YMBJF. The mouse model of CAC was established by combining azoxymethane （AOM， 10 mg·kg^-1） and dextran sulfate sodium （DSS， 2%）. At the 5^th week after the start of modeling， the capecitabine group and the YMBJF groups were respectively administrated with the corresponding doses of drugs by gavage once a day for a total of 6 weeks. The body weights and general conditions of mice were measured and observed， and the disease activity index （DAI） was scored. The tumors in the colorectal tissue were counted， and the colorectal length was measured. The histological features of the colorectal tissue in each group of mice were observed by hematoxylin-eosin （HE） staining. The levels of inflammatory cytokines including interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in the serum were determined by enzyme-linked immunosorbent assay （ELISA）. The expression and localization of proliferating cell nuclear antigen-67 （Ki67）， proliferating cell nuclear antigen （PCNA）， and phosphorylated nuclear transcription factor-κB p65 （p-NF-κB p65） proteins were observed by immunohistochemistry （IHC）. The apoptosis of tumor cells was observed by the TUNEL assay. The mRNA levels of IL-6，IL-1β， TNF-α， nuclear transcription factor-κB p65 （NF-κB p65）， NF-κB inhibitor alpha （IκBα）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in the colorectal tissue were quantified by Real-time polymerase chain reaction（Real-time PCR）. The protein levels of NF-κB p65， phosphorylated （p）-NF-κB p65， IκBα， p-IκBα， Bcl-2， and Bax in the colorectal tissue were determined by Western blot. ResultsCompared with the model group， each YMBJF group showed decreases in DAI and tumor number （P0.01）， and the medium-dose and high-dose YMBJF groups showed increases in colorectal length （P0.05）. In addition， each YMBJF group showed alleviated colorectal mucosal pathological injury， declined levels of IL-6， IL-1β， and TNF-α in the serum （P0.05）， reduced expression of Ki67 and PCNA （P0.01）， and down-regulated expression of p-NF-κB p65 （P0.05）. The apoptosis in the medium-dose and high-dose YMBJF groups increased （P0.01）. Each YMBJF group and the capecitabine group showed down-regulated mRNA levels of IL-1β， TNF-α， IL-6， NF-κB p65， and Bcl-2 （P0.05） and up-regulated mRNA levels of IκBα and Bax （P0.05）. The mRNA level of IκBα was up-regulated， and that of Bcl-2 was down-regulated （P0.05） in the high-dose YMBJF group. The protein levels of p-IκBα and Bcl-2 were down-regulated （P0.05） in each YMBJF group. The protein levels of IκBα and Bax were up-regulated in the medium-dose and high-dose YMBJF groups （P0.01）， while those of NF-κB p65 and p-NF-κB p65 were down-regulated （P0.05）. ConclusionYMBJF can reduce the number of tumors， reduce the levels of inflammatory factors， promote tumor cell apoptosis， and inhibit tumor cell proliferation by regulating the direct effector molecules of the NF-κB signaling pathway in the mouse model of CRC.

Background Exposure to benzo[a]pyrene (BaP) may impair lung function through various mechanisms; however, it remains uncertain whether BaP induces ferroptosis in lung tissue cells, resulting in lung function impairment. Objective To investigate the ferroptosis of lung tissue cells triggered by subchronic BaP exposure in mice and its correlation with lung injury, and to explore the function of ferroptosis in BaP-induced lung tissue damage. Method Seventy-two healthy 3-weeks-old male C57BL/6J mice were acclimatized for 1 week and then randomly divided into six groups: control group (corn oil 10 mL·kg⁻¹), low-dose BaP group (2.5 mg·kg⁻¹), medium-dose BaP group (5 mg·kg⁻¹), high-dose BaP group (10 mg·kg⁻¹), BaP+ferrostatin-1 (Fer-1) group (10 mg·kg⁻¹+1 mg·kg⁻¹), and Fer-1 group (1 mg·kg⁻¹), with 12 mice each group. Corn oil and BaP were administered via gavage every other day, followed by an intraperitoneal injection of Fer-1 the subsequent day, throughout a period of 90 d. Whole-body plethysmography was applied to detect lung function; hematoxylin-eosin staining (HE) and Masson staining were used to observe lung tissue injury and fibrosis; microscopy of alveolar epithelial cells was conducted to reveal mitochondrial morphology; biochemical assays were used to measure the content of tissue iron, malondialdehyde (MDA), and glutathione (GSH), as well as the activity of glutathione peroxidase (GSH-Px); Western blotting and real-time quantitative PCR (RT-qPCR) analyses were performed to reveal the protein and mRNA expression of ferroptosis markers. Results Compared to the control group, the high-dose BaP group showed a significant increase in expiration time (Te) (P<0.01), and a significant decrease in ratio rate of achieving peak expiratory flow (Rpef), tidal volume (TVb), peak inspiratory flow (PIF), minute volume (MVb), and peak expiratory flow (PEF) (P<0.05 or 0.01). Based on the results of HE and Masson staining, partial destruction of alveolar structures, thickening of alveolar walls, infiltration of inflammatory cells, significant thickening of tracheal walls and a large deposition of collagen fibers in lung tissue were observed in the medium- and high-dose BaP groups. By microscopy, the alveolar epithelial cells exposed to low-dose BaP showed condensed chromatin, and the mitochondria exposed to medium and high-dose BaP showed wrinkles, increased mitochondrial membrane density, and diminished mitochondrial cristae. Compared to the control group, in the medium- and high-dose BaP groups, the lung tissue iron content and the expression levels of ACSL4 protein and mRNA significantly elevated (P<0.01 or 0.05), while the mRNA expression level of SLC7A11 significantly decreased (P<0.05); in the high-dose BaP group, the MDA content, COX2 protein, and PTGS2 mRNA expression levels significantly increased (P<0.05 or 0.01), GSH content and GSH-Px activity, GPX4 protein and mRNA expression levels, and the expression level of SLC7A11 protein significantly decreased (P<0.01 or 0.05). The ferroptosis inhibitor Fer-1 markedly reversed respiratory function, morphology, mitochondrial alterations, and the aforementioned ferroptosis-related biochemical indicators. Conclusion Subchronic exposure to BaP can induce ferroptosis in mice lung tissue cells, resulting in compromised lung function.

OBJECTIVE To explore the main factors influencing the blood concentration of duloxetine， and provide a scientific basis for the individualized use of duloxetine. METHODS Retrospective analysis was conducted on 434 inpatients with depressive disorders at the First Hospital of Hebei Medical University， who were treated with duloxetine and underwent blood concentration monitoring between January 2022 and April 2024. The study examined the impact of various factors， including gender， age， body mass index （BMI）， gene phenotypes， combined medication， drug type （original/generic）， and genotyping results of gene single nucleotide polymorphism loci， on blood concentration and the concentration-to-dose （C/D） after dose adjustment. RESULTS The blood concentration of duloxetine was 76.65 （45.57， 130.31） ng/mL， and C/D was 0.96 （0.63， 1.60） ng·d/（mL·mg）. The blood concentration of duloxetine was positively correlated with the daily dose of administration （R2＝0.253 7， P＜0.001）. Blood concentration of duloxetine in 38.94% of patients exceeded the recommended range specified in the guidelines. Gender， age， BMI， combined use of CYP2D6 enzyme inhibitors， and CYP2D6 and CYP1A2 phenotypes had significant effects on C/D of duloxetine （P＜0.05）. CONCLUSIONS The patient’s age， gender， BMI， combined medication， and genetic phenotypes are closely related to the blood concentration of duloxetine.

Objective To explore the regulation of Chaihuang Qingyi Huoxue Granule on intestinal microecological changes in rats with severe acute pancreatitis (SAP) and the potential mechanism for its treatment of SAP. Methods Forty-eight rats were randomly divided into sham operation group (SHAM),SAP model group (SAP),and Chaihuang Qingyi Huoxue Granule (CH)group,with 16 rats in each group. Each group was further divided into 12 h and 24 h subgroups. The SAP model was induced by retrograde injection of 5％ sodium taurocholate into the pancreaticobiliary duct through duodenal wall. The SHAM and SAP groups received normal saline by gavage,while the CH group received 1.2 g·kg-1 Chaihuang Qingyi Huoxue Granule solution by gavage every six hours. At 12 h and 24 h after operation,eight rats from each group were sacrificed to collect abdominal aortic blood,pancreatic and ileal tissues for analysis. Ascites,pancreatic and ileal tissues were observed. Serum amylase(AMY) and lipase (LPS) levels were measured biochemically. Pathological changes in pancreatic and ileal tissues were investigated by HE staining. Claudin-1 protein expression in ileal tissue was detected by Western Blot. Changes in the intestinal flora of ileocecal contents were analyzed by 16S rDNA high-throughput sequencing. Results Compared to the SHAM group at the same time points,the SAP group exhibited extensive pancreatic edema and necrosis. Serum AMY and LPS levels,pancreatic and ileal histopathological scores increased,and Claudin-1 protein expression in ileal tissue markedly decreased (all P<0.05). The differences in abundance of microbial community increased,while the evenness of community composition reduced. The microbial richness showed no significant change (P>0.05),but the microbial diversity decreased(P<0.05). Proteobacteria were dominant intestinal bacteria. Relative abundances of Oscillospira,Ruminococcus,Bifidobacterium,and Bacteroides S24-7 decreased,whereas relative abundances of Shigella and Allobaculum increased. The differences in abundance of microbial community reduced,and the evenness of community composition increased. The microbial richness showed no significant change(P>0.05),but the microbial diversity increased (P<0.05). Firmicutes and Bacteroidetes were the dominant intestinal bacteria. Relative abundances of Oscillospira,Ruminococcus,Bifidobacterium,and Bacteroides S24-7 increased,whereas relative abundances of Shigella and Allobaculum decreased. After the intervention of CH,pathological damage in ileal tissue was improved. The expression of Claudin-1 protein in the intestinal mucosal barrier increased compared to the model group(P<0.05). The differences in abundance of microbial community reduced,and the evenness of community composition increased. CH group showed an increase in some beneficial bacteria and decrease in pathogenic bacteria compared to model group. Conclusion Chaihuang Qingyi Huoxue Granule may reduce pancreas injury in rats with SAP,which may be involved in modulating the intestinal microecology and improving intestinal mucosal barrier function.

Objective To understand the recognition and coping strategies of ICU nurses on post-ICU syndrome in family members of patients during hospitalisation so as to provide a reference for handling post-ICU syndrome of the family members of patients.Methods A phenomenological approach within qualitative research was adopted.Semi-structured in-depth interviews were conducted with 15 ICU nurses from 3 wards of the Second Affiliated Hospital of South China University.Colaizzi 7-step method was applied to analyse and refine the interview data themes.Results Three main themes and nine sub-themes were identified and they were insufficient cognition of post-ICU syndrome of the family members(limited understanding of post-ICU syndrome in family members,difficulty in recognising or ignoring symptoms,uncertainty about the impact of post-ICU syndrome),active coping with post-ICU syndrome of the family members(coping mainly through listening and explaining,coping mainly through verbal and physical actions,diligent patient care)and various factors hindering nurses'coping with post-ICU syndrome of the family members(compassion fatigue,high ICU work intensity,limited contact time with family members).Conclusion ICU nurses have insufficient understanding of post-ICU syndrome with the family members of patients during hospitalisation.It requires to enhance a comprehensive understanding in ICU nurses about post-ICU syndrome of the family members of patients and to optimise coping strategies to alleviate negative emotions of the family members.Additionally,efforts should be made to overcome factors that hinder nurses'coping with post-ICU syndrome of the family members of patients and to promote a harmonious relationship between medical staff and patients.
