Objective:To explore the mechanism of Amomi Fructus in ameliorating ethanol-induced gastric ulcer (GU) in mice using metabolomics, network pharmacology and molecular docking techniques.Methods:The mice were divided into the blank group, model group, aqueous extract of Amomi Fructus group, volatile oil of Amomi Fructus group, combined aqueous extract and volatile oil of Amomi Fructus group and omeprazole group according to the random number table method, with 10 mice in each group. The blank and model groups were gavaged with sodium carboxymethyl cellulose, the Amomi Fructusaqueous extract group was gavaged with 0.152 5 g/kg of Amomi Fructus aqueous extract, the Amomi Fructus volatile oil group was gavaged with 26 μl/kg of Amomi Fructus volatile oil, the Amomi Fructus aqueous extract and volatile oil combined group was gavaged with 0.152 5 g/kg+26 μl/kg of Amomi Fructus aqueous extract and volatile oil synergistic solution, and the omeprazole group was gavaged with 5.2 mg/kg of omeprazole, 1 time/day, which was administered continuously for 7 d. The gastric ulcer model was established by using ethanol 2 h after the last administration, and the pathological changes of gastric histology were observed by using HE staining; the main differential metabolites were detected by UPLC-Q-TOF-MS/MS non-targeted metabolomics technique, and the metabolic pathway enrichment analysis was carried out; the potential targets and key pathways of the anti-GU action of Amomi Fructus were predicted by network pharmacology; the "metabolite-response-enzyme-gene" network was established by combining the serum metabolomics and network pharmacology; and the key targets were verified by molecular docking technology.Results:HE staining showed that the gastric mucosa of mice in the model group was severely damaged, with cellular tissue damage and inflammatory cell infiltration, whereas the drug administration group showed some protective effects; the results of non-targeted metabolomics showed that 2 metabolites were up-regulated and 17 metabolites were down-regulated in sera of mice in the co-administration group of aqueous extract and volatile oil of Amomi Fructus compared with the control group, and the 19 metabolites were strongly correlated and well clustered, involving nicotinic acid and nicotinamide metabolism, citric acid cycle, glyoxylate and dicarboxylic acid metabolism, phenylalanine metabolism, alanine, aspartate and glutamate metabolism and other metabolic pathways; the results of network pharmacology showed that Amomi Fructus improved GU by affecting target proteins, such as STAT3, AKT1, SRC, and TLR4, which were closely linked to the signaling pathways of cancer pathway, human cytomegalovirus infection, and lipids and atherosclerosis; the joint analysis of network pharmacology and the combined analysis of network pharmacology and metabolomics identified the glycerophospholipid metabolic pathway as the main metabolic pathway in which Amomi Fructus may exert gastroprotective effects; the molecular docking results showed that the main active component of quercetin had a better binding ability to the key targets.Conclusion:Amomi Fructus exerts a protective effect on ethanol induced GU model by regulating the glycerophospholipid metabolism pathway, providing theoretical basis for further research on Amomi Fructus.

ObjectiveTo investigate the anti-inflammatory, antioxidant, and goblet cell-stimulating effects of a suspension of Ophiopogon japonicus (L. f.) Ker Gawl. (O. japonicus, Mai Dong) extract combined with hyaluronic acid (HA) in the mouse model with dry eye disease (DED).MethodsA DED mouse model was induced using benzalkonium chloride (BAK), followed by treatment with O. japonicus extract-containing eye drops at varying concentrations. Experimental groups included a normal control, a DED model control, a positive control, and an O. japonicus extract-treated group. Corneal fluorescein staining and tear break-up time (TBUT) were used to assess tear film stability and ocular surface integrity. Enzyme-linked immunosorbent assay (ELISA) measured inflammatory factor levels in corneal and conjunctival tissues, whereas Western blot (WB) analyzed key antioxidant and inflammatory markers, including nuclear factor erythroid 2-related factor (2Nrf2) and heme oxygenase 1 (HO-1). Periodic acid-schiff (PAS) staining and immunofluorescence were used to evaluate goblet cell density and mucin secretion.ResultsO. japonicus extract significantly improved corneal damage, reduced fluorescein staining scores, prolonged TBUT, and increased tear secretion. It downregulated inflammatory markers, including interleukin-8 (IL-8), interleukin-1β (IL-1β), and interferon-γ (IFN-γ) while upregulating Nrf2, HO-1, and the interleukin-13 (IL-13)/IFN-γ ratio, alleviating oxidative stress and inflammation. PAS staining showed increased conjunctival goblet cell density and restored mucin secretion, enhancing tear film stability.ConclusionO. japonicus extract demonstrated significant anti-inflammatory, antioxidant, and goblet cell-stimulating effects in a DED model, with good biocompatibility and promising therapeutic potential. Future research should optimize extraction processes and validate their efficacy and safety in clinical settings.

ObjectiveTo investigate the difference in the level of biliary calprotectin between patients with cholangiocarcinoma and those with choledocholithiasis. MethodsClinical data and bile samples were collected from 34 patients with cholangiocarcinoma and 78 patients with choledocholithiasis who were diagnosed and treated with endoscopic retrograde cholangiopancreatography in The First Affiliated Hospital of Anhui Medical University from May 2021 to September 2022. Fluorescence lateral flow immunoassay was used to measure the levels of calprotectin， hemoglobin， and lactoferrin in bile. The Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups； the Spearman correlation test was used for correlation analysis； the DeLong test was used for comparison of the area under the ROC curve （AUC）. ResultsCompared with the choledocholithiasis group， the cholangiocarcinoma group had significant increases in the levels of calprotectin ［4 795.50 （2 286.79‍ ‍—‍ ‍20 179.73） ng/mL vs 411.16 （67.03‍ ‍—‍ ‍1 991.88） ng/mL， Z=5.572， P<0.001］ and fluoride ［115.70 （109.10‍ — ‍125.50） mmol/L vs 106.60 （98.60‍ ‍—‍ ‍114.40） mmol/L， Z=2.702， P=0.007］. The patients with cholangiocarcinoma were further divided into high cholangiocarcinoma group and low cholangiocarcinoma group， and there was no significant difference between the two groups in the level of calprotectin ［3 867.71 （2 235.66‍ — ‍26 407.40） ng/mL vs 4 795.50 （2 361.15‍ — ‍13 070.53） ng/mL， Z=0.129， P>0.05］. Biliary calprotectin level was correlated with white blood cell count， hemoglobin concentration， and lactoferrin concentration in bile （r=0.316， 0.353， and 0.464， all P<0.05）. The ROC curve analysis showed that biliary calprotectin （with a sensitivity of 79.4% and a specificity of 75.6%）， blood CA19-9 （with a sensitivity of 82.4% and a specificity of 78.2%）， and their combination （with a sensitivity of 88.2% and a specificity of 73.1%） had good sensitivity and specificity in the diagnosis of cholangiocarcinoma. ConclusionThere is an increase in the level of biliary calprotectin in patients with cholangiocarcinoma， and therefore， it might become a biomarker for the diagnosis of cholangiocarcinoma.

Objective To investigate the anticoagulation status of patients with atrial fibrillation(AF)-related acute ischemic stroke(AIS)after revascularization therapy in the real world.Methods A retrospective study was performed on patients diagnosed as AIS and AF from Jan.2019 to Jan.2022 at The Second Affiliated Hospital of Nanchang University.Patients treated with intravenous thrombolysis(IVT),endovascular thrombectomy(EVT),or both were enrolled.Clinical information,timing of anticoagulation initiation,treatment regimens,and outcomes were documented and statistically analyzed.Additionally,a questionnaire was administered to the primary physicians to understand reasons for delaying or not initiating anticoagulation.Results A total of 189 patients with AF-related AIS met the screening criteria,including 86(45.5%)cases in the IVT group,63(33.3%)cases in the EVT group,and 40(21.2%)cases in the IVT+EVT group.The mean age of 189 patients was(72.90±9.23)years old.There were 93(49.2%)female patients.Anticoagulation was initiated within 14 d after revascularization therapy in 36.0%(68/189)of patients,with the highest rate in the IVT group(58.8%,40/68),followed by the EVT group(22.1%,15/68)and IVT+EVT group(19.1%,13/68).A significant difference was found in the proportion of patients receiving anticoagulation within 14 d among the 3 groups(P=0.020).Univariate analysis was performed on the clinical data of patients who initiated anticoagulation within 14 d after revascularization therapy(68 cases)and those who delayed or did not initiate anticoagulation(121 cases).The results showed that there were significant differences in the stroke history,National Institutes of Health stroke scale(NIHSS)score before revascularization therapy,Alberta Stroke Program early computed tomography score,modified Rankin scale(mRs)score before revascularization therapy,imaging characteristics(lesions near cortex,large infarction,severe stenosis or occlusion of major intracranial arteries),revascularization therapy method,NIHSS score 3 d after revascularization therapy,and intracranial hemorrhagic transformation after revascularization therapy between the 2 groups(all P＜0.05).Multivariate logistic regression analysis indicated that higher NIHSS scores 3 d after revascularization therapy(odds ratio[OR]=1.113,95%confidence interval[CI]1.053-1.176,P＜0.001)and the presence of intracranial hemorrhage after revascularization therapy(OR=6.098,95%CI 2.004-18.193,P=0.001)were significant factors that contraindicated the initiation of anticoagulation.Large infarcts(40.8%),infarct location(35.8%),and hemorrhagic transformation after stroke(40.8%)were the common reasons cited by physicians for not initiating anticoagulation.In the 90-d prognosis of patients with AF-related AIS,6 patients had bleeding events,and 116 patients had a good prognosis(mRS score of 0-2).The 90-d good prognosis rate in the initiated anticoagulation group within 14 d after revascularization therapy(89.7%,61/68)was significantly higher than that in the delayed or non-anticoagulation group(45.5%,55/121;P＜0.001).Conclusion For patients with AF-related AIS who receive IVT,EVT or IVT+EVT,it is safe to initiate anticoagulation early after revascularization therapy,but the timing of anticoagulation in most patients is later than the currently recommended anticoagulation timing.

Background and purpose:In 2016 the National Cancer Institute(NCI)decided stopping to use NCI-60 cell lines for drug screening,suggesting that tumor cell lines were losing their value as a tool for drug discovery and basic research.The reason for NCI-60 cells'retirement'was that the preclinical studies based on traditional cellular and animal models did not obtain the corresponding expected efficacy in clinical trials.Since the major cancer behaviors,such as proliferation and metastasis,are fundamentally altered with long-term culture,the tumor cell lines are not representative of the characteristics of cancer in patients.Currently,scientists hope to create a new cancer model that are derived from fresh patient samples and tagged with details about their clinical past.Our purpose was to create patient-derived breast cancer primary cell lines as new cancer model for drug screening and basic research.Methods:Breast cancer tissues were collected in the Department of Breast Surgery,Affiliated Hospital of Guizhou Medical University.The collection of tumor tissue samples was approved by the Ethics Committee of the Affiliated Hospital of Guizhou Medical University(approval number:2022 ethics No.313),and the collection and use of tumor tissues complied with the Declaration of Helsinki.The primary breast cancer cell lines were isolated from the patient's breast cancer tissues and cultured in BCMI medium.After the cells proliferated,the media were replaced with DEME medium.Cell line STR genotyping was done to determine cell-specific genetic markers and identification.Clone formation assay and transplantation assay were done to analyze the ability of breast cancer primary cell lines to form tumors.Results:We created 6 primary breast cancer cell lines.The 6 primary breast cancer cell lines from the patients were tagged with the definitively clinicopathological features,clinical diagnosis,therapeutic regimens,clinical effectiveness and prognostic outcomes.The STR genotyping assays identified the genetic markers and determined the identities of the 6 primary breast cancer cell lines.Clone formation assays and transplantation assay showed that the proliferative capacities of the patient-derived primary breast cancer cell lines were significantly greater compared with the conventional breast cancer cell lines.Conclusion:We created a panel of 6 patient-derived primary breast cancer cell lines as new cancer model for drug screening and basic research in breast cancer.
