ObjectiveBased on the theory of "spleen governing transportation and transformation"， this study investigates the efficacy of Atractylodis Macrocephalae Rhizoma processed with Aurantii Fructus Immaturus juice（AMR-AFI） in improving slow-transit constipation（STC）， as well as the synergistic regulatory mechanism involving the microbiota-metabolism axis， thereby elucidating the scientific basis of its processing theory. MethodsAnimals were randomly divided into the control group， model group， positive drug（mosapride） group（3 mg·kg^-1）， and low-， medium-， and high-dose groups of AMR-AFI（3.9， 7.8， 15.6 g·kg^-1）. Except for the control group， the remaining five groups were induced with STC using loperamide hydrochloride. Following modeling， interventions were administered. All groups received continuous administration for 15 d， during which fecal samples， colon tissue， and serum were collected. Constipation improvement was assessed by measuring fecal moisture content and small intestinal propulsion rate， histological morphology of colonic tissue was observed via hematoxylin-eosin（HE） staining， and the levels of interleukin（IL）-6， tumor necrosis factor（TNF）-α， and IL-2 in serum were detected using enzyme-linked immunosorbent assay（ELISA）. Furthermore， the microbial community structure in mouse feces was analyzed by 16S rRNA sequencing， while transcriptomic sequencing was employed to screen differentially expressed genes in colonic tissue， followed by gene ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） enrichment analyses. Finally， Spearman correlation analysis was conducted to explore the association between differential microbiota and differential genes. ResultsCompared with the control group， the intestinal propulsion rate and fecal moisture content in the model group were significantly decreased（P<0.01）， while serum levels of IL-6， TNF-α， and IL-2 were significantly elevated（P<0.01）. HE staining showed damage and shedding of colonic mucosal epithelial cells， along with a reduction in goblet cells in the model group. In comparison with the model group， all treatment groups improved the pathological state of the colonic mucosa to varying degrees and reduced serum levels of IL-6， TNF-α， and IL-2（P<0.01）. Among these， the high-dose group of AMR-AFI significantly increased the intestinal propulsion rate and fecal moisture content of rats（P<0.05， P<0.01）. Further transcriptomic analysis revealed that a total of 104 differentially expressed genes were identified from comparisons between the model group and the control group， as well as between the model group and the high-dose group of AMR-AFI. These genes were mainly enriched in pathways closely related to STC pathogenesis， such as arachidonic acid metabolism and aldosterone-regulated sodium reabsorption. 16S rRNA sequencing results indicated that AMR-AFI reversed the structural imbalance of the gut microbiota in model mice， increased species richness， downregulated the relative abundance of pro-inflammatory bacteria such as Parasutterella， and enriched beneficial and butyrate-producing bacteria， including Lachnospiraceae_NK4A136_group， Ruminococcaceae， and Lachnospiraceae. Spearman correlation analysis further showed that the beneficial bacteria enriched in the AMR-AFI group were negatively correlated with genes involved in the arachidonic acid metabolic pathway and positively correlated with genes in the aldosterone-regulated sodium reabsorption pathway. In contrast， pro-inflammatory bacteria in the model group exhibited the opposite correlation trends. ConclusionAMR-AFI can effectively exert synergistic therapeutic effects on STC by regulating intestinal microbiota， arachidonic acid-mediated inflammatory metabolism， and aldosterone-regulated water-salt balance pathways.

ObjectiveTo investigate the migration and distribution characteristics of chemical constituents in blood and hippocampal tissues before and after vinegar processing of Citri Reticulatae Pericarpium Viride（CRPV）， and to explore the potential material basis and mechanisms underlying their regulatory effects on emotional disorders by comparing the effects of raw and vinegar-processed products of CRPV. MethodsUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was employed to characterize and identify the chemical constituents of raw and vinegar-processed products of CRPV extracts， as well as their migrating components in blood and hippocampal tissues after oral administration. Reference standards， databases， and relevant literature were utilized for compound annotation， with data processing performed using PeakView 1.2 software. Seventy male C57BL/6 mice were randomly divided into seven groups， including the blank group， model group， diazepam group（2.5 mg·kg^-1）， raw CRPV low/high dose groups（0.6， 1.2 g·kg^-1）， and vinegar-processed CRPV low/high dose groups（0.6， 1.2 g·kg^-1）， with 10 mice per group. Except for the blank group， all other groups underwent chronic restraint stress（2 h·d^-1） for 20 d. Each drug-treated group received oral administration at the predetermined dose starting 10 d after modeling， with a total treatment duration of 10 d. Following model-based drug administration， mice underwent open-field， forced swimming， and elevated plus maze tests. After anesthesia with isoflurane， whole brains were collected from each group of mice， and hippocampi were dissected. Reactive oxygen species（ROS） level in hippocampal tissues was quantified by enzyme-linked immunosorbent assay（ELISA）. Hematoxylin-eosin（HE） staining was used to observe hippocampal tissue morphology. Immunofluorescence was performed to detect neuronal nuclei（NeuN） and peroxisome proliferator-activated receptor alpha（PPARα） expressions in hippocampal tissue. Then， pharmacodynamic evaluations were conducted to assess the effects of raw and vinegar-processed CRPV on mood disorders， exploring the potential mechanisms. ResultsVinegar processing caused significant changes in the chemical composition of CRPV， with 18 components showing increased relative content and 35 components showing decreased relative content. The primary changes occurred in flavonoid compounds， including 20 flavonoids， 20 flavonoid glycosides， 3 triterpenes， 3 phenolic acids， 1 alkaloid， and 6 other compounds. Twenty-one components were detected in blood（15 methoxyflavones， 4 flavonoid glycosides， and 2 phenolic acids）， with 17 shared between raw and vinegar-processed CRPV. Seven components reached hippocampal tissues（all common to both forms）. In regulating emotional disorders， Vinegar-processed CRPV exhibited superior antidepressant-like effects compared to raw products. HE staining revealed that both treatments improved hippocampal neuronal morphology， particularly in the damaged CA1 and CA3 regions. Immunofluorescence and ELISA analyses demonstrated that both raw and vinegar-processed CRPV significantly modulated NeuN and PPARα expressions in hippocampal tissue while alleviating oxidative stress induced by excessive ROS（P<0.05）. ConclusionThe chemical composition of CRPV undergoes changes after vinegar processing， but the migrating components in blood and hippocampus are primarily methoxyflavonoids. These components may serve as the potential material basis for activating the PPARα pathway， thereby negatively regulating ROS generation in the hippocampus， reducing oxidative stress， and promoting the development of NeuN-positive neurons. These findings provide experimental evidence for enhancing quality standards， pharmacodynamic material research， and active drug development of raw and vinegar-processed CRPV.

Background: Isoliquiritigenin, a key pharmacologically active compound derived from the traditional Chinese medicine Glycyrrhizae Radix et Rhizoma, can be further modified into various high-value 5-deoxyflavones, demonstrating significant potential for pharmaceutical development. Currently, the supply of isoliquiritigenin primarily depends on plant extraction. However, heterologous synthesis using microbial cell factories presents a promising alternative, offering a solution to resource limitations caused by the dwindling availability of Glycyrrhiza uralensis. Objective: This study aimed to employ heterologous synthesis in yeast strains for the stable and high-efficiency production of isoliquiritigenin. Methods: First, a stable chassis strain for isoliquiritigenin production was constructed by integrating optimized biosynthetic pathway enzyme genes. A type IV noncatalytic chalcone isomerase-like protein and a synthetic protein scaffold system were employed to enhance the metabolic channeling of key pathway enzymes. Subsequently, yeast metabolism was fine-tuned to balance precursor supply, and cofactor engineering strategies were implemented to increase nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) availability, thereby ensuring the catalytic efficiency of the key enzyme chalcone reductase. Results: The engineered strain Y21-2 achieved a 24.4-fold increase in isoliquiritigenin titer compared to the original strain. Additionally, the proportion of the by-product naringenin chalcone was reduced by 67.8%, marking the first instance in which the ratio of C-5 hydroxylated by-products was minimized to 10.4% during the microbial synthesis of 5-deoxyflavones. Conclusion: This work provides a valuable reference for the efficient and sustainable production of isoliquiritigenin, laying a solid foundation for further pathway optimization and the biotechnological synthesis of other high-value natural 5-deoxyflavones.

Objective To explore the correlation between the ratio of free triiodothyronine/free thyroxine(FT3/FT4)and the early-phase insulin secretion index(ΔI30/ΔG30)in type 2 diabetes mellitus(T2DM)patients with normal thyroid function.Methods 200 patients with T2DM with normal thyroid function in Hebei General Hospital from September 2019 to June 2021 were selected and divided into the Q1 group with FT3/FT4≤0.26(n=67),the Q2 group with 0.27≤FT3/FT4≤0.29(n=67),and the Q3 group with FT3/FT4≥0.30(n=66)according to the tertiles of the FT3/FT4.The general data,biochemical indicators and islet functions of the three groups were compared,and the relationship between the FT3/FT4 ratio and the ΔI30/ΔG30 as well as the islet β cell function was analyzed.Results The fasting insulin(FIns),2 h postprandial insulin(2 hIns),homeostatic model assessment of islet β cell(HOMA-β)and area under the curve of insulin(AUCI)in Q3 group were higher than those in Q1 and Q2 groups(P<0.05),2 h postprandial blood glucose(2 hPG)in Q3 group was lower than those in Q1 and Q2 groups(P<0.05).Systolic blood pressure in Q2 group was higher than those in Q1 group(P<0.05).Compared with Q1 group,diastolic blood pressure,body mass index(BMI),alanine aminotransferase(ALT),fasting C-peptide(FC-P),area under curve of C-P(AUCC),2 h postprandial C-peptide(2 hC-P)and ΔI30/ΔG30 in Q3 group were significantly higher(P<0.05),and HbA1c was significantly lower(P<0.05).Spearman correlation analysis showed that Δ I30/Δ G30,HOMA-β,AUCI,AUCC and HOMA-IR were positively correlated with BMI,ALT,FC-P,2 hC-P,FIns,2 hIns and FT3/FT4(P<0.05),it was negatively correlated with HbA1c and 2 hPG(P<0.05).Linear regression analysis showed that ΔI30/ΔG30,HOMA-β,AUCI and AUCC were the influencing factors of FT3/FT4 after adjusting for confounding factors.Conclusions ΔI30/ΔG30,HOMA-β,AUCI and AUCC are the influencing factors of FT3/FT4 in T2DM patients with normal thyroid function,suggesting that FT3/FT4 is higher in patients with better islet β cell secretion function.

Objective:To compare the treatment time stability, inter- and intra-fraction errors, and clinical target volume (CTV) to planning target volume (PTV) margin expansions under different gated window settings in deep inspiration breath hold (DIBH) radiotherapy for breast cancer, and to analyze the correlation between organ at risk (OAR) dose optimization and changes in lung volume.Methods:A retrospective analysis was conducted on 65 patients with left-sided breast cancer who received DIBH radiotherapy after modified radical mastectomy. CT simulation positioning was performed using 2 mm or 3 mm gated window for DIBH, followed by target delineation, treatment planning, and dose verification. During treatment, setup errors guided by cone beam CT (CBCT), intra-fraction monitoring errors, and treatment times were recorded. The coefficient of variation (CV) of treatment time was calculated for both gated window settings. Based on inter- and intra-fraction error distributions, the expansion distance of the CTV were determined using the van Herk formula. Dosimetric differences between DIBH and free-breathing (FB) plans for the left lung, heart, and left anterior descending coronary artery (LAD) were compared. Spearman correlation analysis was performed between the relative increase in left lung volume and the relative reduction in OAR dose. Paired t-tests were used for inter-group comparisons. Results:The mean CV of the 3 mm gated window group was 0.08±0.03, which was lower than that of the 2 mm group (0.10±0.04; t=-3.91, P<0.001). The setup errors of the 2 mm group in the X, Y, and Z directions were (1.27±1.03), (1.68±0.94), (1.90±1.25) mm, respectively-significantly smaller than those of the 3 mm group [(1.81±1.41), (2.07±1.69), (2.93±1.90) mm; t=-5.80, -2.33, -5.33; P<0.001,=0.014,<0.001). Setup errors for both groups were within the 25%-75% range and all below 5 mm. The intra-fraction deviations of the 2 mm group in the X, Y, and Z directions were (0.54±0.33), (0.79±0.44), (0.70±0.53) mm, respectively, significantly smaller than those of the 3 mm group [(0.62±0.43), (0.93±0.66), (0.87±0.67) mm; t=-3.87, -3.46, -2.71,all P<0.001). The mean intra-fraction errors of both groups were within 1 mm, with greater deviations in the Y and Z directions than those in the X direction. The CTV expansion margins for the 2 mm group in the X, Y, and Z directions were 4.21, 5.35, 5.99 mm, respectively, while those for the 3 mm group were 5.81, 6.89, 9.06 mm. Compared with FB, DIBH significantly reduced the doses to the left lung, heart, and LAD (all P<0.01). The increase in left lung volume was moderately negatively correlated with the reduction in left lung D mean ( r=-0.43, P=0.028), and highly negatively correlated with the dose reductions to the heart and LAD (both P<0.001). Conclusions:The variability in respiratory gated window settings can lead to differences in treatment time stability as well as inter- and intra-fraction errors, consequently affecting CTV-to-PTV margins. The DIBH technique demonstrates significant dosimetric benefits in reducing radiation exposure to the left lung, heart, and LAD. Volumetric expansion of the left lung is strongly and inversely correlated with the reduction in radiation dose to both the heart and LAD.

Pollen allergen-induced allergic rhinitis(AR),also known as seasonal allergic rhinitis(SAR),typically manifests during the period of pollen dissemination by anemophilous plants.The prevalence of SAR has more than doubled over the past three decades.The etiology of SAR is multifaceted,involving factors such as pollen allergens,environmental and climatic conditions,genetic predispositions,and the immunological status of the individual.Animal models provide a critical tool for elucidating the mechanisms underlying AR and advancing the development of effective preventive and therapeutic strategies.This review synthesizes the recent pertinent domestic and international literature on pollen-sensitized AR animal experiments.It systematically delineates the factors influencing the efficacy of these models,including the selection of animal strains,the production and associated challenges of sensitizing agents,specifically pollen antigens,the utilization and limitations of adjuvants,the procedural steps involved in model creation,and the method ologies for evaluating model effectiveness.The insights provided are intended to offer guidance and support for the development of appropriate animal models of pollen-induced AR,thereby facilitating both fundamental and applied research in this area.

Objective: To analyze serological and molecular characteristics of asymptomatic HBV infection in HBV surface antigen positive (HBsAg+) blood donors from Dalian. Methods: The prevalence of HBsAg was analyzed among blood donors in Dalian between 2013 and 2022. Randomly selected HBsAg+ blood samples were subjected to HBV serological testing, HBV viral DNA quantification, and HBV genotyping. Results: Over this ten-year period, the prevalence of HBsAg decreased from 1.25% to 0.50% among blood donors in Dalian. Donors who tested positive for HBsAg prior to donation using a rapid test (RT) accounted for 92.5% of all HBsAg+ donors identified. A total of 240 confirmed HBsAg+ blood donors were randomly selected, including 125 donors with positive results and 115 with negative results in the pre-donation rapid test. HBsAg+ donors were mainly males (71.2%), with a median age of 42, and 97.5% of them being first-time donors. Based on HBV serological profiles, three stages of infection were identified: early infection (2.9%), suspected acute hepatitis (0.8%), and chronic infection (96.3%). The dominant HBV genotypes were C (68.9%) and B (28.4%). Among chronic HBV infection individuals, donors infected with HBV genotype B were older than those infected with genotype C (median age: 45y vs 38.5y, P<0.05). Additionally, they showed significantly lower HBsAg levels with a narrower distribution range than those infected with genotype C [median: 23.2 IU/mL (range: <0.05-7 910 IU/mL) vs 968 IU/mL (range: <0.05-3.4×10 ), P<0.05]. However, no significant difference was observed in the HBV DNA loads between these two genotypes (P>0.05). Conclusion: Between 2013 and 2022, the prevalence of HBsAg among blood donors in Dalian showed a year-over-year decline. Chronic infection was predominant among HBsAg+ first-time blood donors. The characteristics of chronic infection in blood donors differed significantly depending on the viral genotype, manifesting as differences in age of infected individuals and HBsAg level distribution.

The incidence and mortality of colorectal cancer （CRC） in China have been on a steady rise. Current therapeutic approaches can curb the progression of CRC to a certain extent， but issues such as toxic side effects， high metastasis rate， and high recurrence rate cannot be ignored. In recent years， alkaloid components derived from traditional Chinese medicine （TCM） have demonstrated tremendous potential in the prevention and treatment of CRC due to their diverse structures， complex mechanisms， and broad biological activities. Representative alkaloids such as matrine， berberine and evodiamine exert anti-CRC effects through multiple pathways： regulating signaling pathways including Wnt/β-catenin， nuclear factor-κB， signal transducer and activator of transcription 3， and phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin； inhibiting the proliferation， migration， and invasion of CRC cells； inducing cell apoptosis and autophagy； arresting the cell cycle progression； regulating the gut microbiota； suppressing cellular glycolysis； and inducing ferroptosis.

Objective:To discuss whether safranal affects the proliferation,migration,and phenotypic transformation of the vascular smooth muscle cells(VSMCs)in a high-glucose environment and to clarify the function of safranal in the prevention and treatment of diabetic(DM)vascular complications.Methods:The SD rats were selected as experimental subjects;primary VSMCs were cultured from rat thoracic aortas and divided into control group,25 mmol·L-1 high glucose(HG)group,HG+20 μmol·L-1 safranal group,HG+40 μmol·L-1 safranal group,and HG+80 μmol·L-1 safranal group.The cells in control group received no treatment;the cells in 25 mmol·L-1 HG group were pretreated with 25 mmol·L-1 HG;the cells in HG+20,40,and 80 μmol·L-1 safranal groups were further treated with 20,40,and 80 μmol·L-1 safranal respectively for 48 h on the basis of 25 mmol·L-1 HG group.Cell counting kit-8(CCK-8)method was used to determine the appropriate concentration of safranal and detect the viabilities of the VSMCs in various groups;cell scratch healing assay was used to detect the scratch healing rates of the VSMCs in various groups;Transwell chamber assay was used to detect the numbers of the migration VSMCs in various groups;immunofluorescence method was used to detect the fluorescence intensities of alpha-smooth muscle actin(α-SMA)and rabbit anti-osteopontin(OPN)in the VSMCs in various groups;Western blotting method was used to detect the expression levels of OPN,α-SMA,and proliferating cell nuclear antigen(PCNA)in the VSMCs in various groups.Results:Under microscope,on the 4th day of in vitro culture,the spindle-shaped or triangular cells crawled out from the edge of the thoracic aorta tissue blocks,with long spindle being the most common morphology.On the 14th,the cells gradually covered the bottom of the dish;when cell density reached 80%-90%,the characteristic"hills and valleys"growth pattern appeared.Third-generation cells were taken for immunofluorescence identification;immunofluorescence staining with VSMC-specific marker α-SMA showed positive expression of α-SMA protein in the primarily cultured VSMCs.The CCK-8 assay results showed that compared with control group,the cell viability of the cells in 160 μmol·L-1 safranal group was significantly decreased(P<0.01),indicating toxic damage to the cells.Under the conditions of safranal concentrations at 20,40,and 80 μmol·L-1 respectively,after 48 h intervention on VSMCs,no significant adverse effect on cell viability was observed;considering both the effect and toxicity of safranal,these three concentrations were used in subsequent cell experiments.After 48 h intervention,compared with control group,the activity of the VSMCs in 25 mmol·L-1 HG group was increased(P<0.001);compared with 25 mmol·L-1 HG group,the activities of the VSMCs in HG+20,40,and 80 μmol·L-1 safranal groups were gradually decreased(P<0.05).The cell scratch healing assay and Transwell assay results showed that after 48 h intervention,the scratch healing rate of the VSMCs in 25 mmol·L-1 HG group was significantly higher than that in control group(P<0.01),and the number of transmembrane cells through the Transwell chamber was significantly increased(P<0.05);compared with 25 mmol·L-1 HG group,the scratch healing rates of the VSMCs in HG+20,40,and 80 μmol·L-1 safranal groups were gradually decreased(P<0.05),and the number of transmembrane cells was decreased(P<0.05).The immunofluorescence staining results showed that compared with control group,the fluorescence intensity of α-SMA protein in the VSMCs in 25 mmol·L-1 HG group was significantly weakened(P<0.001),while the fluorescence intensity of OPN protein was significantly enhanced(P<0.001);compared with 25 mmol·L-1 HG group,the fluorescence intensities of α-SMA protein in the VSMCs in HG+20,40,and 80 μmol·L-1 safranal groups were gradually increased(P<0.05),and the fluorescence intensities of OPN were gradually weakened(P<0.05).The Western blotting method results showed that compared with control group,the expression level of α-SMA protein in the VSMCs in 25 mmol·L-1 HG group was decreased(P<0.05),and the expression levels of PCNA and OPN proteins were increased(P<0.01);compared with 25 mmol·L-1 HG group,the expression level of α-SMA protein in the VSMCs in HG+20,40,and 80 μmol·L-1 safranal groups were increased(P<0.05),and the expression levels of PCNA and OPN proteins were decreased(P<0.05).Conclusion:Safranal can inhibit the proliferation,migration,and phenotypic transformation of the VSMCs induced by high glucose.
