Objective To study the correlation between Periostin, interleukin-33 (IL-33), and chronic cough after thoracoscopic lobectomy in patients with coronary artery bypass grafting (CABG) combined with lung cancer. Methods A total of 102 lung cancer and coronary heart disease patients at Tianjin Chest Hospital from January 2022 to January 2024 were prospectively enrolled, and they were divided into a chronic cough group (n=42) and a non-chronic cough group (n=60) based on whether chronic cough occurred after surgery. Serum levels of Periostin and IL-33 were measured on the 1st, 7th, and 14th days post-lobectomy. The Pearson method was employed to analyze the correlation between Periostin and IL-33 levels and the severity of cough. Univariate and multivariate logistic regression analyses were conducted to identify factors influencing the occurrence of chronic cough. Additionally, receiver operating characteristic (ROC) curve analysis was utilized to assess the potential value of serum Periostin and IL-33 levels in predicting postoperative chronic cough. Results In patients with chronic cough, the peripheral blood Periostin and IL-33 levels measured on days 7 and 14 were significantly higher than those in patients with non-chronic cough, and the interactions between the two groups and at different time points were significant (P<0.001). The degree of cough was positively correlated with the levels of Periostin and IL-33 on days 7 and 14 (P<0.05), but had no significant correlation with the levels on day 1 (P>0.05). In patients with lung cancer, after thoracoscopic lobectomy, Periostin [OR=1.619, 95%CI (1.295, 2.025)] and IL-33 [OR=1.831, 95%CI (1.216, 2.758)] on day 7 and Periostin [OR=1.952, 95%CI (1.306, 2.918)] and IL-33 [OR=1.742, 95%CI (1.166, 2.603)] on day 14 were identified as risk factors for chronic cough. ROC curve analysis showed that the sensitivity of Periostin on day 7 was 69.05%, the specificity was 71.67%, and the area under the curve (AUC) was 0.756 [95%CI (0.616, 0.893)]. The sensitivity of Periostin on day 14 increased to 71.43% and the specificity was 76.67%, AUC was 0.762 [95%CI (0.633, 0.898)]. At the same time, the critical value of IL-33 on day 7 was 45.03 pg/mL, the sensitivity and specificity were both 83.33%, the AUC was 0.884 [95%CI (0.789, 0.980)], and the critical value of IL-33 on day 14 was 56.01 pg/mL, the sensitivity was 85.71%, the specificity was 80.00%, and the AUC was 0.899 [95%CI (0.799, 0.999)]. Joint logistic regression analysis of Periostin and IL-33 levels on days 7 and 14 showed showed that the sensitivity was 95.24%, the specificity was 95.00%, and the AUC reached 0.993 [95%CI (0.979, 1.000)]. Conclusion Periostin and IL-33 levels, measured at various time points, are abnormally elevated following thoracoscopic lobectomy in patients with combined CABG and lung cancer. These levels significantly correlate with cough severity. Given their predictive potential for chronic cough, these markers are deemed valuable biomarkers.

ObjectiveTo investigate the mechanism by which Shaoyaotang regulates the miRNA-155-mediated suppressor of cytokine signaling 1 (SOCS1)/Janus kinase 1 (JAK1)/signal transducer and activator of transcription 1 (STAT1) signaling pathway and thereby affects macrophage polarization. MethodsThe cell-counting kit-8 (CCK-8) assay was used to detect the effect of drug-containing serum of Shaoyaotang at different concentrations on the viability of RAW 264.7 cells. A cell model of inflammation was established by stimulating RAW264.7 cells with lipopolysaccharide (LPS) at a concentration of 10 mg·L-1 The modeled cells were assigned by the random number table method into seven groups: LPS-induced M1 polarization (model), M1+miRNA-155 mimics, M1+miRNA-155 inhibitor, M1+Shaoyaotang-containing serum, M1+miRNA-155 mimics+Shaoyaotang-containing serum, M1+miRNA-155 inhibitor+Shaoyaotang-containing serum, and M1+blank serum. Enzyme-linked immunosorbent assay was employed to measure the levels of inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β)]. Immunofluorescence assay was used to detect the expression of macrophage polarization markers [inducible nitric oxide synthase (iNOS) and macrophage mannose receptor 1 (CD206)]. Real-time PCR was employed to measure the expression of miRNA-155 in cells. Western blot was performed to determine the protein levels of SOCS1, STAT1, and JAK1. ResultsCompared with the LPS-induced M1 polarization (model) group, the M1+miRNA-155 mimics group showed up-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and down-regulated expression of CD206 (P<0.05). In both the M1+miRNA-155 inhibitor group and the M1+Shaoyaotang-containing serum group, the expression levels of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS were down-regulated (P<0.05), while those of SOCS1 and CD206 were up-regulated (P<0.05). Compared with the M1+miRNA-155 mimics group, the M1+miRNA-155 mimics+Shaoyaotang-containing serum group showed down-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and up-regulated expression of SOCS1 and CD206 (P<0.05). Compared with the M1+miRNA-155 inhibitor group, the M1+miRNA-155 inhibitor+Shaoyaotang-containing serum group showed down-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and up-regulated expression of SOCS1 and CD206 (P<0.05). ConclusionShaoyaotang regulates macrophage polarization by modulating miRNA-155 expression and interfering with the SOCS1/JAK1/STAT1 signaling pathway. The findings provide new experimental evidence for the treatment of ulcerative colitis with Shaoyaotang.

ObjectiveTo investigate the potential role and underlying mechanisms of Shaoyaotang in intervening macrophage glycolytic reprogramming in ulcerative colitis (UC). MethodsForty-eight C57BL/6 mice were randomly divided into six groups: Normal control group, model group, mesalazine group (0.39 g·kg-1), Shaoyaotang group (15.54 g·kg-1), 2-deoxy-D-glucose (2-DG) group (glycolysis inhibitor, 100 mg·kg-1), and 2-DG + Shaoyaotang combined group (100 mg·kg-1+15.54 g·kg-1). Except for the normal control group, mice in the other five groups were induced to establish UC models using dextran sulfate sodium (DSS). The normal control group was administered pure water via intragastric gavage, while the other groups received intragastric gavage of mesalazine solution, intragastric gavage of Shaoyaotang, and the 2-DG group was treated with 2-DG via intraperitoneal injection. After 7 consecutive days of treatment, colonic tissues were extracted. Hematoxylin and eosin (HE) staining was performed to evaluate histopathological changes and tissue injury in the colon. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) in colonic tissues. Western blot analysis was employed to determine the expression levels of hypoxia-inducible factor-1α (HIF-1α), glucose transporter (GLUT1), lactate dehydrogenase A (LDHA), pyruvate kinase M2 (PKM2), and 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3) in colonic tissues. Immunofluorescence was conducted to detect the expression of CD206 and inducible nitric oxide synthase (iNOS) in colonic tissues. Liquid chromatography-mass spectrometry (LC-MS) was utilized to measure lactate and citrate levels in colonic tissues. ResultsCompared with the normal control group, mice in the model group exhibited a significant increase in disease activity index (DAI) scores, accompanied by colonic mucosal congestion, edema, and inflammatory cell infiltration, significantly elevated expression of the inflammatory cytokine TNF-α (P<0.05), significantly decreased IL-10 expression (P<0.05), significantly increased levels of HIF-1α, GLUT1, LDHA, PKM2, and PFKFB3 in colonic tissues (P<0.05), markedly elevated iNOS expression (P<0.05), significantly decreased CD206 expression (P<0.05), and significantly elevated lactate and citrate levels in colonic tissues (P<0.05). In contrast to the model group, the Shaoyaotang group, inhibitor group, and Shaoyaotang combined with inhibitor group demonstrated amelioration of mucosal injury in colonic tissues, markely decreased expression levels of the inflammatory cytokine TNF-α (P<0.05), elevated IL-10 expression levels, significantly decreased expression of HIF-1α, GLUT1, LDHA, PKM2, and PFKFB3 (P<0.05), markedly reduced iNOS expression levels (P<0.05), significantly increased CD206 expression (P<0.05) and significantly decreased lactate and citrate levels (P<0.05). ConclusionShaoyaotang ameliorates symptoms of DSS-induced UC in mice, and its therapeutic mechanism may be associated with regulating macrophage glycolytic reprogramming via modulation of the HIF-1α signaling pathway.

ObjectiveTo investigate the role of microRNA-155-5p (miR-155-5p) in ulcerative colitis (UC) and study the molecular mechanism of Shaoyaotang in the treatment of UC by regulating miR-155-5p. MethodsForty-eight SPF-grade male C57BL/6 mice were selected and assigned via the random number table method into 6 groups (n=8): A blank control group, a model group, a mesalazine (0.39 g·kg-1) group, a Shaoyaotang (31.08 g·kg-1) group, a Janus kinase 1 (JAK1) inhibitor (baricitinib, 10 mg·kg-1) group, and a Shaoyaotang combined with inhibitor (baricitinib 10 mg·kg-1 + Shaoyaotang 31.08 g·kg-1) group. After successful modeling of UC by gavage of 3% dextran sulphate sodium solution, each group received corresponding drug intervention for 7 days. Shaoyaotang and mesalazine were administered by gavage, and baricitinib by intraperitoneal injection. Twenty-four hours after the last administration, mice were anesthetized by intraperitoneal injection of pentobarbital sodium, and blood was collected for determination of white blood cell count and erythrocyte sedimentation rate (ESR). Mice were then sacrificed for measurement of colon length. Hematoxylin-eosin staining was used to observe colonic pathological changes and perform pathological scoring. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was employed to determine the relative expression of miR-155-5p in the colonic tissue, and Western blot was used to determine the protein levels of JAK1, phosphorylated JAK1 (p-JAK1), suppressor of cytokine signaling 1 (SOCS1), signal transducer and activator of transcription 1 (STAT1), and phosphorylated STAT1 (p-STAT1). ResultsCompared with the blank control group, the model group showed increased disease activity index (DAI) score and pathological score, shortened colon, upregulated relative expression of miR-155-5p and protein levels of p-JAK1 and p-STAT1, downregulated protein level of SOCS1 in the colonic tissue, prolonged time of erythrocyte sedimentation, and increased white blood cell count (P<0.01). Compared with the model group, all drug-treated groups exhibited improvements in the above indicators (P<0.01). Moreover, the Shaoyaotang group showed better therapeutic effects than the mesalazine group in regulating miR-155-5p expression, related protein levels, DAI score, and colonic pathological score (P<0.01). ConclusionShaoyaotang may downregulate miR-155-5p to relieve its inhibition on SOCS1, thereby suppressing the excessive activation of the JAK1/STAT1 signaling pathway and ultimately alleviating intestinal inflammatory damage.

Objective:To explore the role and possible mechanism of ACOT11 in renal fibrosis model mice.Methods:A mouse model of renal fibrosis was established by unilateral ureteral obstruction(UUO)(Sham group and UUO7 group),and the expression of ACOT11 in the kidneys of UUO induced fibrosis mouse models was detected by protein immunoblotting and real-time fluorescence quantitative PCR(qRT-PCR).Subsequently,immunohistochemistry,Masson staining,H&E staining,PAS staining,and other experimental methods were used to detect the expression levels of fibrosis biomarkers fibronectin,α-SMA,and COL-1 in the kidneys of control and experimental group mice.In addition,by constructing ACOT11 gene knockout model mice and using the gene knockout model mice to construct a renal fibrosis model,the expression levels of fibrosis biomarkers such as fibronectin,α-SMA,COL-1,as well as fibrosis mechanism pathway related indicators TGF-β and Smad2 in the kidneys of each group of mice were further detected.Results:The results of WB and qRT-PCR experiments showed that the expression of ACOT11 in the kidney tissue of UUO model mice was significantly reduced compared to the Sham group.After knocking out the ACOT11 gene,H&E staining,PAS staining,and Masson staining showed that pathological inflammatory reactions such as abnormal glomerular and tubular structures,inflammatory cell infiltration and interstitial fibrous tissue proliferation in mice were significantly aggravated compared to the control group,and the expression of fibrosis markers Fibronectin,α-SMA,and COL-1 was significantly higher than that of the control group.Conclusion:ACOT11 plays a protective role in mice with unilateral ureteral obstruction model.After ACOT11 gene knockout,the fibrosis biomarkers of the mouse kidney increases and the degree of fibrosis worsens.

To investigate the phenotype and genomic characterization of a mucoid-type Salmonella Saintpaul ST50 isolate from a urinary tract infection patient,promoting clinical diagnosis and treatment for urinary tract infections caused by Salmo-nella spp.Culture-based quantitative counts of midstream urine sample from the patient were conducted,and further biochemi-cal identification,mass spectrometry detection,serum agglutination test and antimicrobial susceptibility test(AST)were con-ducted on Salmonella isolate(2024JD5).Whole-genome sequencing(WGS)was performed on isolate 2024JD5 to predict sero-type,multilocus sequence type(MLST),resistance genes,and virulence genes.Two smooth-type of Salmonella Saintpaul ST50 were selected as comparative genomic reference strains from the Chinese local Salmonella genome database.The literature reviews of global Salmonella serotype of urinary tract infection were summarized.Specific serum agglutination confir-mation of isolate 2024JD5 failed due to characterization of the mucus type.The strain 2024JD5 was predicted as Salmonella Saintpaul(4,5,12:e,h:1,2)ST50 using WGS,and was resistant to ciprofloxacin,nalidixic acid,chloramphenicol and tetracy-cline with carrying aminoglycoside resistance genes aac(6')-Ⅰaa and aph(3)-Ⅱa,chloramphenicol resistance gene floR,tetra-cycline resistance gene tet,quinolone resistance gene qnrS1,and S83Y substitution in the gyrA gene was found in the quinolo-ne resistance determination region(QRDR).In addition,the strain 2024JD4 carried six types of non-plasmid-based mobile ge-netic elements and 144 virulence genes,including 71 secretion transporter genes and 58 fimbriae adhesion genes,respectively.Four types of fimbriae regulatory genes(csgB,csgC,fimW,fimY)were absent in comparison with smooth-type Salmonella Saintpaul.The literature reviews showed Salmonella Saintpaul was currently a rare Salmonella serotype in cases of urinary tract infections worldwide.Salmonella Saintpaul ST50 with mucoid-type is the pathogen of urinary tract infection with multi-drug resistant phenotypic and genotypic characteristics,and the high mucoid expression may be related to the compensatory mechanism of fimbriae regulatory genes absence in urinary tract colonization and adaptation.WGS combined with the Chinese local Salmonella genome database can effectively solve the diagnosis and biosafety assessments of rare Salmonella phenotypes.

Objective:To evaluate the effect of acupuncture on postoperative delirium (POD) in diabetic patients undergoing surgery under general anesthesia.Methods:In this randomized controlled trial, 92 diabetic patients of either sex, aged 30-80 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were divided into 2 groups ( n=46 each) using a table of random numbers: control group (group C) and acupuncture group (group A). Group A received acupuncture at the Baihui (GV20), Shenting (GV24) and Sishencong (EX-HN1) acupoints before anesthesia. The needles were retained for 30 min, with manual stimulation applied every 10 min for 10 s each time. After 4 stimulations, routine anesthesia was carried out. Group C received routine anesthesia only. Regional cerebral oxygen saturation was recorded on admission to the operating room (T 0), after anesthesia induction (T 1), at the start of surgery (T 2), at the end of surgery (T 3), and immediately after tracheal extubation (T 4). The POD developed within 3 days after surgery was assessed. The occurrence of needle-related adverse effects such as fainting, subcutaneous bleeding, and local paresthesia was recorded. Results:Compared with group C, the incidence of POD was significantly reduced, and the regional cerebral oxygen saturation was increased at T 1, 4 in group A ( P<0.05). Conclusions:Acupuncture can decrease the development of POD in diabetic patients undergoing surgery under general anesthesia, which is related to an increase in regional cerebral oxygen saturation.
