Salvia miltiorrhiza (S. miltiorrhiza) represents a crucial component of traditional Chinese medicine, demonstrating effects on blood circulation activation and stasis removal, and has been widely utilized in asthma treatment. This study isolated a novel phenolic acid (S1) from S. miltiorrhiza and investigated its anti-asthmatic activity and underlying mechanisms for the first time. An allergic asthma (AA) model was established using ovalbumin (OVA). The mechanism of S1's effects on AA was investigated using multi-factor joint analysis, flow cytometry, and co-culture systems to facilitate clinical asthma treatment. S1 (10 or 20 mg·kg^-1) was administered daily to mice with OVA-induced AA (OVA-AA) during days 21-25. The study examined airway responsiveness, lung damage, inflammation, and levels of immunoglobulin E (IgE), PGD2, interleukins (IL-4, 5, 10, 13, 17A), tumor necrosis factor α (TNF-α), GM-CSF, CXCL1, CCL11, and mMCP-1. Additionally, mast cell (MC) activation and degranulation were explored, along with T helper type 17 (Th17)/Treg immune cells and TLR4 pathway biomarkers. The antagonistic activity of that specific antagonist of TLR4 (TAK-242) (1 µmol·L^-1), a specific TLR4 blocker, against S1 (10 µmol·L^-1) was examined in co-cultured 16HBE cells and bone marrow-derived cells (BMDCs) or splenic lymphocytes (SLs) induced with LPS (1 µg·mL^-1) to elucidate the TLR4 pathway's mediating role. S1 demonstrated reduced airway responsiveness, lung damage, and inflammation, with downregulation of IgE, PGD2, interleukins, TNF-α, GM-CSF, CXCL1, CCL11, and mMCP-1. It also impeded MC activation and degranulation, upregulated IL-10, and influenced Th17/Treg immune cell transformation following OVA challenge. Furthermore, S1 inhibited the TLR4 pathway in OVA-AA mice, and TLR4 antagonism enhanced S1's positive effects. Analysis using an OVA-AA mouse model demonstrated that S1 alleviates AA clinical symptoms, restores lung function, and inhibits airway response. S1's therapeutic effects occur through regulation of Th17/Treg immune cells and inflammation, attributable at least partially to the TLR4 pathway. This study provides molecular justification for S1 in AA treatment.

Obesity is a significant risk factor for cancer and is associated with breast cancer metastasis. Nevertheless, the mechanism by which alterations in systemic metabolism affect tumor microenvironment (TME) and consequently influence tumor metastasis remains inadequately understood. Herein, we found that perturbations in circulating metabolites induced by obesity promote metastasis-like phenotypes in breast cancer. Oleoylcarnitine (OLCarn) concentrations were elevated in the serum of obese mice and humans. Administration of exogenous OLCarn induces metastasis-like characteristics in breast cancer cells. Mechanistically, OLCarn directly interacts with the Arg176 site of adenylate cyclase 10 (ADCY10), leading to the activation of ADCY10 and enhancement of cAMP production. Mutations at Arg176 prevent OLCarn from binding to ADCY10, disrupting the ADCY10-mediated activation of cyclic adenosine monophosphate (cAMP) signaling pathway. This activation promotes transcription factor 4 (TCF4)-dependent kinesin family member C1 (KIFC1) transcription, thereby driving breast cancer metastasis. Conversely, the neutralization of both ADCY10 and KIFC1 through knockdown or pharmacological inhibition abrogates the oncogenic effects mediated by OLCarn. Hence, obesity-induced systemic environmental changes lead to the aberrant accumulation of OLCarn within the TME, making it a potential therapeutic target and biomarker for breast cancer.

Objective To explore the distribution characteristics of endogenous metabolites in Crocus sativus L. corms from different origins. Methods A method based on desorption electrospray ionization mass spectrometry imaging and optimized sample pretreatment was developed for directly visualize metabolites in C. sativus corms. Results In situ characterization of metabolites such as flavonoids, organic acids, amino acids, carotenoids, and cyclic enol ether terpene glycosides was achieved. L-Citruline, phenylacetylglycine, sativol, and geniposide were specifically distributed in the corms. Apigenin 7-（6''-O-acetyl）-glucoside, isorhamnetin-3-O-β-D-Glucoside, dhurrin 6'-glucoside, and Apigenin 7-O-diglucuronide were mainly distributed in the terminal bud. For compounds distributed in the corms, the highest abundance was found in corms from Shanghai, followed by Zhejiang and the lowest from Anhui. Conclusion The distribution of metabolites in different parts of C. sativus corms from different origins and the same origin varies significantly. Flavonoids and flavonoid derivatives such as isorhamnetin-3-O-β-D-Glucoside and apigenin derivatives are mainly distributed in the terminal buds, in addition, the natural plant protection agent dhurrin 6'-glucoside is also mainly distributed in the terminal corms, whereas amino acids, which are used as energy and material supplies, are mainly accumulated in the corms.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To explore the causal association of glucose-lipid metabolism and obesity indicators with myocardial infarction by a two-sample Mendelian randomization analysis.Methods:Single nucleotide polymorphisms (SNPs) related to phenotypes were obtained from genome-wide association study databases. The body mass index (BMI) and glycated hemoglobin dataset includes 99 998 samples and 8 126 035 SNPs; the waist-to-hip ratio dataset includes 224 459 samples and 2 562 516 SNPs; the waist circumference and hip circumference dataset includes 462 166 samples and 9 851 867 SNPs; the fasting glucose dataset includes approximately 12 million SNPs; the low-density lipoprotein cholesterol (LDL-C) dataset includes 201 678 samples and 12 321 875 SNPs; the high-density lipoprotein cholesterol (HDL-C), and triglycerides dataset includes 156 109 samples and 15 784 414 SNPs; and the body fat percentage, whole-body fat mass, trunk fat percentage, and trunk fat mass dataset includes 454 588 samples and 9 851 867 SNPs. This study primarily used inverse-variance weighted method to analyze the associations between various exposure factors and outcomes. Heterogeneity among SNPs was assessed using Cochran′s Q test, and horizontal pleiotropy of SNPs was examined using the MR-Egger method. Additionally, a multivariable MR approach was used to adjust for BMI, further validating associations between exposure factors and the risk of myocardial infarction. Results:Higher BMI ( OR=1.070, 95% CI: 1.041-1.100), waist-to-hip ratio ( OR=1.366, 95% CI: 1.113-1.677), LDL-C ( OR=1.638, 95% CI: 1.488-1.803), triglycerides ( OR=1.445, 95% CI: 1.300-1.606), waist circumference ( OR=1.841, 95% CI: 1.650-2.055), hip circumference ( OR=1.247, 95% CI: 1.132-1.372), body fat percentage ( OR=1.795, 95% CI: 1.568-2.055), whole-body fat mass ( OR=1.519, 95% CI: 1.381-1.670), trunk fat percentage ( OR=1.538, 95% CI: 1.374-1.723), and trunk fat mass ( OR=1.421, 95% CI: 1.294-1.561), as well as lower HDL-C ( OR=0.799, 95% CI: 0.729-0.875), have causal effects on myocardial infarction (all P<0.05). After adjusting for BMI, hip circumference, trunk fat percentage, and trunk fat mass were no longer associated with myocardial infarction. However, waist-to-hip ratio ( OR=1.457, 95% CI: 1.132-1.877), fasting glucose ( OR=1.191, 95% CI: 1.024-1.383), glycated hemoglobin ( OR=1.129, 95% CI: 1.034-1.233), LDL-C ( OR=1.592, 95% CI: 1.314-1.929), triglycerides ( OR=1.410, 95% CI: 1.279-1.553), waist circumference ( OR=1.922, 95% CI: 1.448-2.551), body fat percentage ( OR=1.421, 95% CI: 1.072-1.884), and whole-body fat mass ( OR=1.295, 95% CI: 1.031-1.626) remained positively associated with myocardial infarction, while HDL-C ( OR=0.809, 95% CI: 0.729-0.897) remained negatively associated. Conclusions:Abdominal obesity and dysregulation of glucose-lipid metabolism are risk factors for myocardial infarction. Screening for glucose-lipid metabolism (fasting glucose, HDL-C, LDL-C, triglycerides) and obesity-related indicators (waist circumference, waist-to-hip ratio, body fat percentage, and whole-body fat mass) is of great importance for the primary prevention of myocardial infarction.

Objective:To explore the association between aldehyde dehydrogenase 2 (ALDH2) gene polymorphisms and abnormal liver function-induced by acetaminophen (APAP) drugs.Methods:An ALDH2 gene knockout mouse model was constructed using CRISPR/Cas9 gene editing technology. The obtained heterozygous mice were mated with opposite sex of heterozygotes. Genomic DNA was extracted from the tail of the offspring mouse. The polymerase chain reaction (PCR) method was used to determine the ALDH2 genotype. APAP was further used to induce acute drug-induced liver injury models in wild-type and ALDH2 knockout mice. Blood and liver tissues of mice were collected for liver function index, HE staining, F4/80 immunohistochemistry, and other detections. The intergroup mean was compared using a one-way ANOVA. The LSD-? t test was used for pairwise comparison. Results:ALDH2 knockout mice were bred successfully. The genotyping of the offspring was segregated into the wild-type (ALDH2 +/+), heterozygous mutant (ALDH2 +/-), and homozygous mutant (ALDH2 -/-), respectively. Biochemical and histological results after APAP modeling showed that the level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin (TBil) was not significantly increased in the blank control group ( P ?

Objective To evaluate the effect of para-esophageal and para-gastric vessels(PEPGV)on endoscopic secondary prophylaxis for varices.Methods The clinical data of patients with cirrhosis-related esophagogastric varices(EGV)who underwent endoscopic variceal ligation and/or obliteration,and had hepatic venous pressure gradient(HVPG)result between January 2020 and December 2020 in Zhongshan Hospital,Fudan University were retrospectively analyzed.Patients were divided into a group without PEPGV and a group with PEPGV based on CT imaging of the portal vein.The main outcome was 2-year re-bleeding.Results A total of 69 patients were included,and 27 of them had PEPGV.There was no statistical difference in baseline characteristics,blood indexes(included hemoglobin level,prothrombin time and albumin level),HVPG,and the secondary prophylactic endoscopic treatment ways between the two groups.A total of 25 patients experienced re-bleeding within 2 years after endoscopic treatment,including 15 in the group with PEPGV and 10 in the group without PEPGV.Kaplan-Meier analysis showed that the cumulative 2-year re-bleeding rate was significantly higher in the group with PEPGV than in the group without PEPGV(60.07％vs 32.79％,P=0.022).Further multivariate Cox analysis showed that PEPGV was an independent predictor of re-bleeding after endoscopic treatment in EGV patients(HR=2.33,95％CI 1.01-5.39,P=0.047).Conclusions The PEPGV is an independent predictor of re-bleeding after endoscopic treatment in EGV patients.It is suggested that when patients with EGV receive endoscopic treatment to prevent re-bleeding,portal vascular CT is suggested to evaluate PEPGV.For patients with giant extraluminal vascular masses,fully evaluating other treatment options such as transjugular intrahepatic portosystemic shunt,or adjusting endoscopic treatment ways is recommended.

Alcoholic steatohepatitis (ASH) is a liver disease characterized by steatosis, inflammation, and necrosis of the liver tissue as a result of excessive alcohol consumption. Pregnane X receptor (PXR) is a xenobiotic nuclear receptor best known for its function in the transcriptional regulation of drug metabolism and disposition. Clinical reports suggested that the antibiotic rifampicin, a potent human PXR activator, is a contraindication in alcoholics, but the mechanism was unclear. In this study, we showed that the hepatic expression of fatty acid binding protein 4 (FABP4) was uniquely elevated in ASH patients and a mouse model of ASH. Pharmacological inhibiting FABP4 attenuated ASH in mice. Furthermore, treatment of mice with the mouse PXR agonist pregnenolon-16α-carbonitrile (PCN) induced the hepatic and circulating levels of FABP4 and exacerbated ASH in a PXR-dependent manner. Our mechanism study established FABP4 as a transcriptional target of PXR. Treatment with andrographolide, a natural compound and dual inhibitor of PXR and FABP4, alleviated mice from ASH. In summary, our results showed that the PXR-FABP4 gene regulatory axis plays an important role in the progression of ASH, which may have accounted for the contraindication of rifampicin in patients of alcoholic liver disease. Pharmacological inhibition of PXR and/or FABP4 may have its promise in the clinical management of ASH.
