ObjectiveTo observe the changes in the levels of different subtypes of epidermal growth factor receptor (ErbB), namely ErbB1, ErbB2, ErbB3, and ErbB4, in the spinal dorsal horn of inflammatory pain model rats, and to explore their mechanism of mediating hyperalgesia as well as the intervention mechanism of electroacupuncture at "Zusanli (ST 36)" and "Kunlun (BL 60)". MethodsThe study was divided into five parts. In experiment 1, 14 Sprague Dawley (SD) rats were randomly divided into control and inflammatory pain group (7 rats each group) to observe the pain behavior and the protein expression of different ErbB receptor subtypes in the spinal dorsal horn. In experiment 2, 30 rats were randomly divided into control group 1, inflammatory pain group 1, and low-, medium-, and high-concentration TX1-85-1 groups, with 6 rats in each group, to observe the effect of inhibiting spinal ErbB3 on inflammatory pain. In experiment 3, 12 rats were randomly divided into control virus group and ErbB3 knockdown virus group, with 6 rats in each group, to observe the effect of knocking down ErbB3 in the spinal dorsal horn on inflammatory pain. In experiment 4, 44 rats were randomly divided into control group 2, inflammatory pain group 2, electroacupuncture group, and sham electroacupuncture group, with 11 rats in each group, to observe the effect of electroacupuncture. In experiment 5, 40 rats were randomly divided into control group 3, inflammatory pain group 3, electroacupuncture group 1, and electroacupuncture + NRG1 group, with 10 rats in each group, to observe the effect of activating ErbB3 on electroacupuncture. A rat model of inflammatory pain was established by subcutaneous injection of 100 μl of complete Freund's adjuvant into the sole of the unilateral hind foot of SD rats. Rats in the low-, medium-, and high-concentration TX1-85-1 groups were intrathecally injected with ErbB3 inhibitor TX1-85-1 on day 5 to day 7 after modeling. Rats in the ErbB3 knockdown virus group were injected with ErbB3 knockdown virus packaged with adenovirus vector-based short hairpin RNA (shRNA) into the spinal dorsal horn in situ 3 weeks before modeling. Rats in each electroacupuncture group received electroacupuncture at bilateral "Zusanli (ST 36)" and "Kunlun (BL 60)" from day 1 to day 7 after modeling, with dense-sparse waves at a frequency of 2 Hz/100 Hz and a current of 0.5-1.5 mA for 30 minutes once a day. Rats in the electroacupuncture + NRG1 group were intrathecally injected with ErbB3 ligand recombinant human neuregulin-1 (NRG1) after electroacupuncture intervention from day 5 to day 7 after modeling. The mechanical withdrawal threshold and thermal withdrawal latency of rats were measured on day 1, 3, 5, and 7 after modeling to evaluate behavior, and Western Blot was used to detect the protein and phosphorylation levels of each ErbB subtype in the spinal dorsal horn. ResultsCompared with the control group, rats in the inflammatory pain group showed decreased mechanical withdrawal threshold and thermal withdrawal latency of rats, and increased expression of phosphorylated ErbB3 (p-ErbB3) protein in the spinal dorsal horn on days 1, 3, 5, and 7 after modeling (P<0.01). On day 5 and day 7 after modeling, compared with the inflammatory pain group 1, the mecha-nical withdrawal threshold and thermal withdrawal latency of rats in the medium- and high-concentration TX1-85-1 groups increased, and the expression of p-ErbB3 protein decreased (P<0.05). On day 1, 3, 5, and 7 after modeling, compared with the control virus group, the mechanical withdrawal threshold and thermal withdrawal latency of rats in the ErbB3 knockdown virus group increased (P<0.05). On day 5 and day 7 after modeling, compared with the inflammatory pain group 2 and the sham electroacupuncture group, the mechanical withdrawal threshold and thermal withdrawal latency of rats in the electroacupuncture group increased, and the expression of p-ErbB3 protein decreased (P<0.05). On day 5 and day 7 after modeling, compared with the electroacupuncture + NRG1 group, the mechanical withdrawal threshold and thermal withdrawal latency of rats in the electroacupuncture group 1 increased (P<0.05). ConclusionThe p-ErbB3 in the spinal dorsal horn involved in hyperalgesia in rats with inflammatory pain, and electroacupuncture at "Zusanli (ST 36)" and "Kunlun (BL 60)" can alleviate inflammatory pain by inhibiting the expression of p-ErbB3 protein in the spinal dorsal horn of rats.

ObjectiveThe Golgi apparatus serves as a central hub in the eukaryotic secretory pathway, responsible for the processing, sorting, and trafficking of proteins and lipids. In mammalian cells, the Golgi typically forms a perinuclear ribbon-like structure composed of laterally connected cisternae stacks.The maintenance of Golgi ribbon structure depends on the balance of membrane flux across multiple intracellular trafficking pathways, yet the specific contributions of distinct trafficking branches to Golgi macroscopic morphology remain elusive. In mammalian cells, the Golgi ribbon is typically organized as a perinuclear, laterally connected structure composed of stacked cisternae, and its integrity is highly dynamic and sensitive to perturbations in membrane trafficking. This study aims to elucidate the role of coat protein complex I (COPI)-mediated retrograde transport in maintaining the Golgi ribbon and to dissect the functional relationship between the transmembrane cargo receptors LEPROT/LEPROTL1 (LEPROTs) and the COPI adaptor GOLPH3. MethodsUsing siRNA interference and gene-deficient cell lines, we selectively perturbed COPI- or adaptor protein complex 1 (AP-1)-mediated trafficking pathways in HeLa cells. To quantitatively evaluate Golgi morphology, we employed a “Golgi Angle”-based measurement to assess its circumferential distribution around the nucleus. The spatial distribution of the Golgi ribbon was quantitatively analyzed using confocal microscopy, while Golgi ultrastructure and vesicle density were examined via transmission electron microscopy. Additionally, the subcellular distribution of COPI components was assessed by immunofluorescence co-localization. ResultsSelective inhibition of COPI retrograde transport significantly induced the circumferential extension of the Golgi ribbon around the nucleus, whereas blocking AP-1-mediated anterograde transport resulted in Golgi compaction, indicating opposing roles. These results suggest that different trafficking branches downstream of ARF1 exert distinct and even antagonistic effects on Golgi morphology. LEPROTs-deficient cells exhibited a Golgi extension phenotype highly consistent with COPI impairment. Furthermore, knockdown of GOLPH3 in a LEPROTs double-knockout background produced a significant additive effect on Golgi extension, suggesting that LEPROTs and GOLPH3 play non-redundant roles in regulating COPI-related trafficking processes. Mechanistically, loss of either LEPROTs or GOLPH3 led to the aberrant accumulation of COPI components at endoplasmic reticulum exit sites, accompanied by a reduction in COPI-like vesicles around the Golgi. This redistribution indicates a defect in COPI recycling between the ER-Golgi interface and the Golgi apparatus. Ultrastructural analysis revealed that Golgi cisternae in defective cells became shorter and thicker while maintaining a stable number of stacks. In parallel, the density of Golgi-associated vesicles was markedly decreased, further supporting an impairment in COPI vesicle formation or budding processes. ConclusionThis study demonstrates that active COPI retrograde transport is a critical factor in restricting the over-connection of the Golgi ribbon and maintaining its compactness. Rather than causing fragmentation, partial disruption of COPI function leads to a distinct morphological outcome characterized by Golgi ribbon extension at the light microscopy level and cisternal remodeling at the ultrastructural level. LEPROTs and GOLPH3 cooperatively promote the recycling and vesiculation of COPI components, thereby imposing a structural constraint on the Golgi periphery. Our findings support a model in which multiple adaptor proteins act in parallel to sustain efficient COPI cycling, thereby maintaining Golgi structural homeostasis. These findings provide new cell biological evidence for the membrane trafficking basis of Golgi morphological homeostasis.

The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) is higher among individuals with inflammatory bowel disease (IBD) than in the general population. Emerging evidence indicates that the development of MASLD in patients with IBD may occur independently of traditional metabolic risk factors, suggesting a unique pathophysiological mechanism distinct from conventional MASLD pathways. Bile acids (BAs), which act as critical signaling molecules in enterohepatic circulation, play an essential role in maintaining gastrointestinal homeostasis through bidirectional gut–liver axis communication. These molecules are increasingly recognized as pivotal regulators in the progression of both MASLD and IBD. While previous studies have characterized the dynamics of BA in blood or fecal samples under both conditions, a comprehensive understanding of their metabolic profiles and the associated interactions within the gut–liver axis is still lacking. This review synthesizes current evidence from studies employing BA metabolomics to investigate IBD and MASLD. By focusing on BA signatures, we summarize conserved alterations between these two conditions and their potential mechanisms of disease progression. Our review advances understanding of BA-mediated pathways in IBD and MASLD, providing a foundation for assessing their roles in contributing to the pathogenesis of MASLD in patients with IBD.

Objective:
To examine the impacts of chemotherapy/radiotherapy, targeted therapy, and combined treatment on the quality of life in patients with intermediate and advanced lung cancer.
Methods:
The patients with intermediate and advanced lung cancer undergoing chemotherapy/radiotherapy, targeted therapy, and combined treatment for the first time were recruited from a tertiary hospital in Weifang City, Shandong Province, using a quota sampling method in September 2023. Basic information was collected using a general information questionnaire, and the quality of life was assessed using the Chinese version of Functional Assessment of Cancer Therapy-General. The investigation started on the 7th day of treatment, and the follow-ups were conducted at 3 and 6 months. The quality of life in patients with different treatment regimens and at different treatment time were compared using repeated measure analysis of variance.
Results:
There were 26 chemotherapy/radiotherapy patients, 32 targeted therapy patients, and 95 combination therapy patients. There were no significant differences in age, gender, place of residence, education level, self-rated economic status, medical insurance, pathological type and disease stage among the three treatment regimens (all P>0.05). The repeated measure analysis of variance showed an interaction effect between time and group among patients receiving the three treatment regimens (P<0.05). The quality of life scores of patients receiving combination therapy decreased with extended treatment time (all P<0.05). The quality of life scores of patients receiving targeted therapy at 3 and 6 months were lower than those treated for 7 days (both P<0.05). No significant differences were observed in quality of life scores among chemotherapy/radiotherapy patients with different treatment durations (all P>0.05). At 3 and 6 months, patients receiving combination therapy had lower quality of life scores compared to those receiving chemotherapy/radiotherapy or targeted therapy (all P<0.05).
Conclusion
The decline in quality of life for patients with intermediate and advanced lung cancer undergoing chemotherapy/radiotherapy and targeted therapy is less than that for patients receiving combined therapy.

ObjectiveTo investigate the optimal ratio of goat horn replacing antelope horn in Fufang Lingjiao Jiangya pills and the blood pressure-lowering mechanism of this medicine. MethodsThe blood pressure-lowering efficacy of Fufang Lingjiao Jiangya pills with varying proportions of goat horn replacing antelope horn was evaluated on spontaneous hypertensive rats (SHR). In this experiment, 50 SHR rats were randomly grouped as follows: model (n=8), captopril (0.01 g·kg-1) (n=6), low-dose blank Fufang Lingjiao Jiangya pills (0.342 g·kg-1) (n=6), high-dose blank Fufang Lingjiao Jiangya pills (0.684 g·kg-1) (n=6), low-dose antelope horn-containing Fufang Lingjiao Jiangya pills (0.378 g·kg-1) (n=6), high-dose antelope horn-containing Fufang Lingjiao Jiangya pills (0.756 g·kg-1) (n=6), low-dose goat horn-containing Fufang Lingjiao Jiangya pills (0.378 g·kg-1) (n=6), and high-dose goat horn-containing Fufang Lingjiao Jiangya pills (0.756 g·kg-1) (n=6). Additionally, 8 WKY rats were used as the normal group. Drugs were administered by gavage for 4 weeks while an equal volume of distilled water was administered for the normal and model groups. Blood pressure was measured before administration, 3 h post administration, and biweekly thereafter. In the experiment for Fufang Lingjiao Jiangya pills with goat horn replacing antelope horn in different proportions, 48 SHR rats were randomly grouped as follows: model, blank Fufang Lingjiao Jiangya pills (0.684 g·kg-1), antelope horn-containing Fufang Lingjiao Jiangya pills (0.756 g·kg-1), 2× goat horn-containing Fufang Lingjiao Jiangya pills (0.824 g·kg-1), 4× goat horn Fufang Lingjiao Jiangya pills (0.969 g·kg-1), and 6× goat horn Fufang Lingjiao Jiangya pills (1.112 g·kg-1). The normal group included 8 WKY rats, and the normal group and model group received an equal volume of distilled water. The treatment lasted for 2 weeks, and blood pressure was recorded at various time points (pre-administration, 3 h post administration, and on days 4, 7, 10, and 14 of administration). Serum levels of angiotensin-converting enzyme (ACE), angiotensin Ⅱ(Ang Ⅱ), renin, and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay. Histopathological changes in the heart, kidney, and thoracic aorta were observed by hematoxylin-eosin staining. The protein levels of ACE2, angiotensin Ⅱ type 1 receptor (AT1R), and angiotensinogen (AGT) in the kidney tissue were determined by Western blot, while the expression of nuclear factor (NF)-κB p65 and Toll-like receptor 4 (TLR4) in the thoracic aorta tissue was assessed by immunohistochemistry. ResultsCompared with the model group, all treatment groups showed lowered blood pressure (P<0.05, P<0.01), and the 6× goat horn-containing Fufang Lingjiao Jiangya pills group showed consistent blood pressure-lowering effect with the antelope horn-containing Fufang Lingjiao Jiangya pills group. Compared with the normal group, the model group showed elevated serum levels of ACE, Ang Ⅱ, renin, and IL-6, while the elevations were declined in the Fufang Lingjiao Jiangya pills groups (P<0.05, P<0.01). Pathological changes in the heart, kidney, and thoracic aorta were alleviated in all the treatment groups, with the 6× goat horn- and antelope horn-containing Fufang Lingjiao Jiangya pills groups exhibited the best effect. Western blot and immunohistochemistry results showed that all the treatment groups exhibited down-regulated protein levels of AT1R, AGT, NF-κB p65, and TLR4 and up-regulated protein levels of ACE2 (P<0.05, P<0.01) compared with model group, with the 6×goat horn- and antelope horn-containing Fufang Lingjiao Jiangya pills groups showcasing the best effect. ConclusionReplacing antelope horn with 6×goat horn in Fufang Lingjiao Jiangya pills can achieve consistent blood pressure-lowering effect with the original prescription. The prescription may exert the effect by inhibiting the renin-angiotensin-aldosterone system (RAAS) and TLR4/NF-κB signaling pathways.

Aromatic Chinese medicinal essential oils are volatile oils extracted from aromatic Chinese herbs, which can prevent and treat respiratory infectious diseases through multiple synergistic mechanisms including pathogen inhibition, immune regulation, and inflammatory response regulation. Essential oils are primarily used externally on the body to prevent infections and alleviate symptoms through methods like inhalation, smearing, topical application, bathing, gargling or as a suppository. They can also be utilized in the environment for disinfection and air purification, through methods like diffusion, vaporization, or spraying. The external application of essential oils extracted from Chinese aromatic herbs has the advantages of convenience, quick absorption, and simultaneous influence on both the body and mind. However, there are still challenges and deficiencies in aspects such as the positioning of functions, indications, safety, and the research on the mechanism of action. It has been proposed to combine the theory of aromatic Chinese medicinals with the characteristics of essential oils, and formulate prescriptions of Chinese medicinal essential oils under the principles of traditional Chinese medicine syndrome differentiation, and prevent and treat respiratory infectious diseases efficiently, accurately, and safely, thereby expanding the clinical application of aromatic Chinese medicinals and the preventive theory of traditional Chinese medicine.

Objective:
To explore the plasma metabonomic characteristics of patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome.
Methods:
One hundred and three patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome were enrolled from November 2023 to February 2024 in the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine and 54 healthy individuals were recruited. The general data of the two groups were analyzed, and the plasma metabolite content was detected using ultra-high performance liquid chromatography-Orbitrap mass spectrometry. Construct an orthogonal partial least squares discriminant analysis model to screen metabolites with significant intergroup changes. The variable importance in projection≥ 1, |log2FC|>1, and P<0.05 were used as the criteria for the screening of differential metabolites. Annotate differential metabolites using internal databases and the human metabolome database, and perform pathway analysis using MetaboAnalyst website.
Results:
There was no statistically significant difference in gender and age between the two groups.Seventeen potential differential metabolites were identified. The D-4′-phosphopantothenate, 2, 6-dichloroindophenol, 4-methylphenol, hypoxanthine, 11, 12-epoxyeicosatrienoic acids, oleamide, 3-phenyllactic acid contents were higher in patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome than in healthy individuals(P<0.05); 3-anisic acid, 3-iodo-octadecanoic acid, mebendazole, β-alanine, citric acid, trans-aconitic acid, geranyl diphosphate, lysophosphatidylcholine(18∶2), phosphatidylethanolamine(18∶1), and caprolactam contents were lower in patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome than in healthy individuals(P<0.05). Ten metabolic pathways were identified, including the key metabolic pantothenate and coenzyme A biosynthesis pathways.
Conclusion
Metabolic differences were observed between patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome and healthy individuals, and the underlying mechanism may involve the pantothenate and coenzyme A biosynthesis pathways, jointly mediated by D-4′-phosphopantothenate and β-alanine.

Objective:To investigate the methodological differences in the detection, the inflammatory markers and the pathogenic epidemiological characteristics of influenza A virus in clinical laboratories, in order to provide more diagnostic and epidemiological data for diagnosis and prevention for children with influenza A.Methods:A retrospective cross-sectional study was conducted to collect 96 731 patients with suspected influenza A from January 2016 to October 2024 in Nanyang City Center Hospital from the Clinical Laboratory Testing Information System, including 5 731 patients with confirmed influenza A, aged 5.2 (2.8, 43.7) years old. We analyzed the distribution of influenza A patients from age and mixed infections, the relationship between patient age and positive detection rate by restricted cubic spline (RCS), analyzed differences in testing methods used Kappa consistency testing and receiver operating characteristic (ROC) curves, established a model of inflammatory markers by logistic regression, as well as developed a prediction model and also the mutation of the hemagglutinin (HA) sequence of the influenza A subtype H3N2 virus using evolutionary tree analysis.Results:RCS analysis showed an inverted 'S' shaped non-linear relationship between the positive detection rate of influenza A and the age groups of the patients. Among the mixed infections, 1.43%(1 352/94 867) of the cases were combined with Mycoplasma pneumoniae infection. The Kappa values of reverse transcription PCR (RT-PCR) and serological indirect immunofluorescence assay (IFA) for detecting influenza A in nasopharyngeal swabs and alveolar lavage fluid in clinical laboratories were 0.632 and 0.809, respectively, and those of magnetic particle chemiluminescence assay were 0.614 and 0.668, respectively, and the area under curves in ROC curve of IFA and RT-PCR were 0.869 and 0.792, respectively. The inflammatory indexes were usually elevated in severe children compared with mild children. By binary logistic regression model analysis, neutrophil-to-lymphocyte ratio, D-dimer/fibrinogen and prognosis nutrition index were the risk factors and serum amyloid A/C reactive protein ratio was the protective factor for severe children with influenza A, and the OR values of the above factors were 1.760, 7.076, 1.045, and 0.719, respectively, and P<0.01. By the Bayesian Interdiction Criterion, the optimal seasonal autoregressive moving average mixed model for influenza A epidemics was ARIMA (1, 1, 1) (2, 1, 2) 12 with the highest prediction accuracy of 98.63%. The seven strains of H3N2 all belonged to the same isoforms, with nucleotide similarity of the HA gene ranging from 99.5% to 99.9%, and the glycosylation site, receptor-binding site, and the conserved amino acid residue Glycosylation sites, receptor binding sites and conserved amino acid residues remained unchanged. HA sequence analysis showed that the prevalent strains in Nanyang had undergone mutation to different degree compared with the vaccine strains. Conclusion:Scientific and rational testing and characteristic inflammatory markers in the clinical laboratory are of great clinical value in the diagnosis of children with severe influenza A. At the same time, the epidemiological monitoring of influenza A variants should be strengthened.
