ObjectiveThis paper aims to observe the role of Danlou tablet in treating coronary heart disease (CHD) with phlegm-stasis intermingling syndrome in minipigs by improving platelet function and explore the potential pharmacological mechanism of Danlou tablet in regulating platelet function by using proteomics technology. MethodsThirty Bama minipigs were randomly divided into a normal control group (6 pigs) and a high-fat diet group (24 pigs). After 2 weeks of high-fat diet feeding, the high-fat diet group was randomly subdivided into a model group, an atorvastatin group (1 mg·kg-1), and Danlou tablet groups (0.6 g·kg-1 and 0.3 g·kg-1). All groups continued to receive a high-fat diet for 8 weeks after the procedure. The normal control group was given a regular diet, underwent only coronary angiography, and did not receive an interventional injury procedure. The model group and each administration group were fed a high-fat diet. Two weeks later, they underwent a coronary angiography injury procedure. After the procedure, drugs were mixed into the feed every morning for 8 consecutive weeks, with the minipigs maintained on a continuous high-fat diet during this period. Quantitative proteomics technology was further used to study platelet proteins, and differential proteins were obtained by screening. Bioinformatics analysis was performed to analyze key regulatory proteins and biological pathways involved in the therapeutic effect of Danlou tablet on CHD with phlegm-stasis intermingling syndrome. ResultsCompared with the normal control group, the model group showed a significant increase in total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) of minipigs' serum (P<0.01), a significant shortening in prothrombin time of (PT) (P<0.01), a coagulation function index, and an increase in whole blood viscosity (P<0.01) and platelet aggregation rate (P<0.01). Moreover, the platelet morphology was altered, and the contents of endothelin-1 (ET-1) and nitric oxide (NO) were significantly increased (P<0.01). Hemodynamic parameters were obviously abnormal, including significantly decreased systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), left ventricular systolic pressure (LVSP), and left ventricular maximal positive dp/dt (LV+dp/dtmax) (P<0.01). Left ventricular maximal negative dp/dt (LV-dp/dtmax) was significantly increased (P<0.01). Besides, there were myocardial cell hypertrophy, obvious edematous degeneration, massive interstitial inflammatory cell infiltration, high degree of fibrosis, and coronary endothelial atherosclerosis. TC and TG levels in minipigs' serum were significantly reduced in Danlou tablet groups with 0.6 g·kg-1 and 0.3 g·kg-1 (P<0.05, P<0.01), compared with those in the model group. LDL-C was decreased in the Danlou tablet group with 0.6 g·kg-1 (P<0.05). The whole blood viscosity under low and high shear conditions was significantly reduced in the Danlou tablet group with 0.6 g·kg-1 (P<0.05). In groups with all doses of Danlou tablet, maximum aggregation rate (MAR) and average aggregation rate (AAR) were significantly decreased (P<0.05, P<0.01), and platelets' morphological changes such as pseudopodia extension were reduced. ET-1 levels in the serum were significantly reduced. In the Danlou tablet group with 0.6 g·kg-1, NO level in the serum was reduced (P<0.05). In groups with all doses of Danlou tablet, DBP and MAP were significantly increased (P<0.05). In the Danlou tablet group with 0.6 g·kg-1, LVSP and LV+dp/dtmax were significantly increased (P<0.05, P<0.01), and LV-dp/dtmax was significantly decreased (P<0.05). In groups with all doses of Danlou tablet, edematous degeneration in myocardial tissue was milder, and coronary artery lesion degree was significantly alleviated. Compared with the normal control group, there were 94 differentially expressed proteins in the model group, including 81 up-regulated and 13 down-regulated proteins. Compared with the model group, the Danlou tablet group with 0.6 g·kg-1 showed 174 differentially expressed proteins, including 100 up-regulated and 74 down-regulated proteins. A total of 30 proteins were reversed after Danlou tablet intervention. Bioinformatics analysis revealed that its pharmacological mechanism may exert anti-platelet activation, aggregation, and adhesion effects through biological pathways such as regulation of actin cytoskeleton, platelet activation pathway, Fcγ receptor-mediated phagocytosis, as well as proteins such as growth factor receptor-bound protein 2 (GRB2), Ras-related C3 botulinum toxin substrate 2 (RAC2), RAC1, and heat shock protein 90 alpha family class A member 1 (HSP90AA1). ConclusionDanlou tablet can effectively reduce platelet activation and aggregation, exerting a good therapeutic effect on CHD with phlegm-stasis intermingling syndrome in minipigs. Its pharmacological mechanism may involve regulating biological pathways such as actin cytoskeleton and platelet activation pathway, as well as proteins like GRB2, RAC2, RAC1, and HSP90AA1, thereby exerting a pharmacological effect in anti-platelet activation, aggregation, and adhesion.

ObjectiveThis paper aims to observe the protective effect of Huamoyan granules on knee osteoarthritis (KOA) and explore whether its protective effect is oriented toward an anti-inflammatory direction by regulation of macrophage polarization, which can effectively inhibit the progression of pathological inflammatory response, reduce the release of inflammatory pain mediators, and downregulate the protein expression level of transient receptor potential vanilloid 1 (TRPV1), so as to provide experimental evidence for its clinical application and investigate its action mechanism. MethodsAfter adaptive feeding, Sprague-Dawley (SD) rats were randomly divided into six groups: sham group, model group, celecoxib group, and high, medium, and low-dose synovitis granule groups (9.6, 4.8, 2.4 g·kg-1). The administration dose of celecoxib capsules was 20 mg·kg-1. There were 10 rats in the sham group and 12 rats in the model group and each administration group. A KOA animal model was established by means of intra-articular injection of sodium iodoacetate into the knee joint. From the 10th day of the experiment, each administration group was given intragastric administration at a dose of 10 mL·kg-1 for 4 weeks. General conditions of rats in each group were assessed daily. The pressure pain threshold (PPT) to mechanical stimulation and joint diameter were recorded. X-ray examination was performed on the right knee joints of rats for imaging analysis. Enzyme linked immunosorbent assay (ELISA) was performed to detect the tumor necrosis factor-α (TNF-α), serum interleukin-1β (IL-1β), and other pro-inflammatory cytokines in rat serum samples, as well as the expression levels of neurogenic inflammatory mediators such as nerve growth factor (NGF) and calcitonin gene-related peptide (CGRP). Histopathological changes in the knee joint synovial tissues were examined by hematoxylineosin (HE) staining. Safranin O-fast green staining was performed to observe and evaluate the degree of knee cartilage lesions. Western blot was employed to quantitatively analyze TRPV1, p38 mitogen-activated protein kinase (p38 MAPK), and phosphorylated (p)-p38 MAPK in rat knee synovial tissues. Immunofluorescence (IF) was used to measure and assess M1/M2 macrophage polarization. ResultsCompared with those in the sham group, the circumference and joint diameter of the right knee were markedly enlarged in the model group (P<0.01), while PPTs of rats showed a significant reduction (P<0.01). The contents of IL-1β, TNF-α, CGRP, and NGF in rats' serum were significantly elevated (P<0.01), and the synovial Krenn score was increased (P<0.01). The Mankin score of cartilage tissue was increased (P<0.01), and the protein expressions of TRPV1 and p-p38 MAPK/p38 MAPK were significantly upregulated (P<0.01). The experimental intervention significantly reduced the proportion of pro-inflammatory M1 macrophages in the total macrophage population (P<0.01), and the percentage of M2 macrophages was decreased (P<0.01). The M1/M2 macrophage ratio was significantly elevated (P<0.01). Knee joint diameters of all dose groups of Huamoyan granules and the celecoxib group were reduced (P<0.01) compared with those of the model group, and the PPT recovery speeds in the high and medium-dose groups of Huamoyan granules were more obvious (P<0.05). The contents of IL-1β, CGRP, and NGF in the rats' serum in all administration groups were significantly reduced (P<0.05, P<0.01), and the content of TNF-α in rats' serum was significantly reduced (P<0.01). All dose groups of Huamoyan granules demonstrated significant reductions in both synovial Krenn score (P<0.05, P<0.01) and protein expression of TRPV1 and p-p38 MAPK/p38 MAPK in rats' synovial tissues (P<0.01). The percentage of M1 macrophages in the synovial tissues of the celecoxib group and all dose groups of Huamoyan granules was decreased (P<0.01). The percentage of M2 macrophages was increased (P<0.05), and the M1/M2 ratio was decreased (P<0.01). ConclusionHuamoyan granules can alleviate the inflammatory response of KOA, reduce the release of inflammatory pain mediators, and downregulate TRPV1 protein expression by regulating macrophage polarization. Its mechanism may be related to the TRPV1/p38 MAPK signaling pathway, thereby achieving the effect of improving peripheral pain hypersensitivity in KOA.

Background Co-exposure to noise and microwave radiation occurs frequently. The central nervous system has been identified as a sensitive target organ for both noise and microwave exposure individually, and the underlying mechanisms remain poorly understood. The specific biological effects resulting from co-exposure to these two factors have yet to be fully elucidated. Objective To clarify the effects of co-exposure to noise and microwave on neurobehavior and hippocampal tissue structure, and to explore the underlying mechanism through the assessment of serum cytokines. Methods C57BL/6N mice were selected and randomly assigned to a blank control group, a noise group, a microwave group, and a combined noise & microwave exposure group. To establish the exposure models, the noise group was subjected to broadband noise at 100 dB for 2 h, while the microwave group received radiation at a central frequency of 9.375 GHz with an average power density of 12 mW·cm−2 and a specific absorption rate of 2.58 W·kg−1 for 15 min. Open field and tail suspension tests assessed anxiety-like emotional behaviour; novel object recognition and Y-maze tests evaluated cognitive function. Histological changes in hippocampal tissue were examined using haematoxylin and eosin (HE) staining, and Nissl staining under light microscopy. Serum cytokine levels were measured using radioimmunoassay and enzyme-linked immunosorbent assay (ELISA). Results After 3 d of exposure, the noise, microwave, and combined exposure groups showed significant reductions in exploration frequency, duration, and distance within the central zone of the open field test compared to the control group (P < 0.01); the combined exposure group exhibited increased ratios of peripheral-to-central exploration time and distance (P < 0.05). After 7 d of exposure, compared with the control group, the noise group maintained a decrease in central zone exploration time (P < 0.01), while the combined exposure group showed persistent decline across all central zone metrics (P < 0.05) and elevated peripheral-to-central ratios (P < 0.05); compared to the microwave group, the combined exposure group showed significant less time in the central zone (P < 0.05) and higher peripheral-to-central ratios (P < 0.05). Regarding behaviour and cognition, compared with the control group, the combined exposure group showed increased immobility time in the tail suspension test after 3 d of exposure (P < 0.01). At this interval, all exposure groups demonstrated reduced frequency and duration of novel object recognition (P < 0.05), with the combined exposure group showing a marked decrease in novel arm exploration time (P < 0.01). After 7 d of exposure, compared with the control group, the noise group showed reduced novel object recognition frequency (P < 0.05), and both the noise and microwave groups exhibited decreased novel arm exploration time (P < 0.05). Pathological alterations including an increased number of hyperchromatic nuclei and depleted Nissl bodies were observed in the CA3 and DG regions across all exposure groups with the most severe lesions observed in the combined exposure group. Serum levels of central nervous system-specific protein β (S-100β), glial fibrillary acidic protein (GFAP), and corticosterone (CORT) were significantly elevated in all exposure groups compared with the control group (P < 0.05). Aquaporin-4 (AQP4) levels increased in the combined exposure group (P < 0.05), while CXC chemokine ligand 10 (CXCL10) levels rose in both the noise and combined groups compared with the control group (P < 0.05). Specifically, S-100β and CXCL10 levels in the combined exposure group were higher than those in the microwave group (P < 0.05); moreover, levels of S-100β, GFAP, CORT, AQP4, and CXCL10 in the combined exposure group were significantly higher than those in the noise group (P < 0.05). Conclusion Combined exposure to noise and microwave radiation induces pathological changes in the hippocampus of mice, increases levels of serum stress hormones and neuro-specific biomarkers. These impairments are more severe than those observed following single-factor exposure. The underlaying mechanism may be related to systemic stress response, neuronal damage, astrocyte activation, and changes in blood-brain barrier permeability, leading to emotional behavioral abnormalities and cognitive decline.

ObjectiveThe malaria parasites remodel the host erythrocyte structure by exporting parasite proteins that interact with the membrane skeleton proteins of red blood cells (RBCs), facilitating their intracellular survival and pathogenicity. Skeleton-binding protein 1 (SBP1) is a conserved exported protein across Plasmodium species. In Plasmodium falciparum, SBP1 has been reported to interact with erythrocyte membrane skeleton proteins 4.1R and spectrin, while its contribution to erythrocyte remodeling and parasite virulence in Plasmodium berghei (Pb) remains unclear. This study aims to determine whether PbSBP1 associates with the host cytoskeletal protein 4.1R and to investigate its role in the remodeling of host RBCs and the pathogenicity of Plasmodium berghei. MethodsIn Plasmodium berghei, the relationship between PbSBP1 and the erythrocyte cytoskeletal protein 4.1R was examined using co-immunoprecipitation. A Pbsbp1 gene knockout mutant of Plasmodium berghei (Pbsbp1∆) was generated based on the principle of double crossover homologous recombination. The deformability of erythrocytes infected with Pbsbp1∆ parasites was assessed using microfluidic methods. Microchannels with an array of cylindrical pillars were used to detect modifications in infected RBC deformability. The infected RBCs were squashed between the rows and recovered between the columns and the transit velocity (μm/s) of infected RBCs travelling through the microchannel was recorded. The component of the erythrocyte membrane skeleton junctional complex, tropomodulin (TMOD), was fluorescently labeled, and the cytoskeletal network of infected erythrocytes was imaged using super-resolution stochastic optical reconstruction microscopy (STORM) to analyze ultrastructural changes in the cytoskeleton of wild-type (WT) and Pbsbp1∆-infected erythrocytes. Actin-based junctional complexes were displayed as individual clusters by the labeled TMOD in the STORM images, and the cluster densities and distances between adjacent clusters of infected RBCs were calculated. Additionally, rodent malaria models (BALB/c mice) and experimental cerebral malaria models (C57BL/6 mice) were employed to monitor the growth of Pbsbp1∆ and WT parasites during the intraerythrocytic stage and their capacity to induce cerebral malaria in mice. ResultsPbSBP1 may participate in the remodeling of infected erythrocytes through direct or indirect interaction with the erythrocyte cytoskeletal protein 4.1R. Microfluidic assays revealed that the deformability of erythrocytes infected with Pbsbp1∆ parasites was significantly enhanced compared to those infected with WT parasites. STORM imaging further demonstrated that the ultrastructure of the erythrocyte cytoskeleton in Pbsbp1∆-infected cells was altered relative to that in WT-infected erythrocytes. The distances between nearest neighbors of clusters had a tendency to increase while the cluster densities were decreased in Pbsbp1∆-infected RBCs compared to WT-infected RBCs. Subsequent phenotypic analysis indicated that the growth rate of Pbsbp1∆ parasites during the intraerythrocytic stage was significantly slower than that of WT parasites, and their ability to induce cerebral malaria in mice was also attenuated. These findings suggest that PbSBP1 is involved in the remodeling of the erythrocyte membrane skeleton, likely through its direct or indirect interaction with protein 4.1R, thereby regulating the deformability of infected erythrocytes and influencing the pathogenicity of the blood-stage parasites. ConclusionThis study establishes a role for PbSBP1 in host erythrocyte remodeling and parasite virulence, providing new research strategies for the prevention and treatment of malaria.

Exportin 1 (XPO1) is aberrantly overexpressed in various malignant tumors and can lead to the loss of anti-tumor effects of important tumor suppressor proteins such as p53, RB1, and FOXO by mediating their nuclear export. Although XPO1 inhibitor Selinexor has entered clinical application, its single-agent anti-tumor activity remains suboptimal, which is closely related to the compensatory activation of multiple signaling pathways in response to XPO1 inhibition. Focusing on the core regulatory role of XPO1 in tumor cells, this article systematically summarizes the current landscape of combination therapies involving XPO1 inhibitors and various targeted agents, including inhibitors of CDK4/6, FLT3, BET, ATR, and BCL2/MDM2, aiming to provide some reference for the development of XPO1-centered combination therapy strategies.

ObjectiveTo explore the mechanisms of Qingchang Wenzhong Decoction (清肠温中方, QWD) in treating ulcerative colitis (UC). MethodsA total of 100 male C57BL/6J mice were assigned to a pseudo-germ-free group (n=45) and a conventional group (n=55) using a random number table. Pseudo-germ-free model was established by giving antibiotic treatment and subsequently subjected to acute UC induction. After the model was successfully established, the 45 pseudo-germ-free acute UC mice were randomly allocated to a pseudo-germ-free model group, a pseudo-germ-free QWD group, and a pseudo-germ-free mesalazine group, with 15 mice in each group. The 55 conventional mice were randomly divided into a normal control group (n=10), as well as a conventional model group, a conventional QWD group, and a conventional mesalazine group, with 15 mice in each group. Except for the normal control group, acute UC models were established in all other groups. Mice in the control group received no intervention. From day 32 of the experiment, mice in the pseudo-germ-free QWD group and the conventional QWD group were administered with QWD granules at a dose of 9.71 g/(kg·d) by gavage with deionized water, while those in the pseudo-germ-free mesalazine group and the conventional mesalazine group were given mesalazine enteric-coated tablets at a dose of 151.67 mg/(kg·d) by gavage. Mice in the remaining groups received an equal volume of deionized water once daily for 7 consecutive days. On day 25 of the experiment, six mice were randomly selected from both the pseudo-germ-free group and the conventional group to measure body weight, and fecal samples were collected for 16S rDNA sequencing to compare differences in gut microbiota, including operational taxonomic units (OTUs), Shannon index, Observed_species index, and phylogenetic diversity (PD whole tree). On day 39, body weight was measured in all groups, and the disease activity index (DAI) was evaluated. Colon length and colon wet weight were recorded. Histopathological changes in colonic tissues were assessed by hematoxylin and eosin (HE) staining, and histological injury scores were determined. In addition, the expression levels of mucopolysaccharides and mucin 2 (MUC2) in colonic tissues were measured. ResultsOn day 25, there was no significant difference in body weight between the pseudo-germ-free group and the conventional microbiota group (P>0.05). Compared to the conventional microbiota group, the pseudo-germ-free group showed significantly reduced OTUs, Shannon index, Observed_species index, and PD whole tree (P<0.01). On day 39, compared to the normal control group, mice in the conventional model group showed a significant decrease in the body weight and an increase in DAI, along with increased colon wet weight, shortened colon length, markedly elevated histopathological scores, and reduced expression of mucopolysaccharides and MUC2 (P<0.01). In contrast, no significant differences were observed in these parameters in the pseudo-germ-free model group (P>0.05). Compared to the conventional model group, the conventional QWD group showed significant improvement in all measured parameters, whereas the conventional mesalazine group showed reductions only in DAI scores and colon wet weight (P<0.01). No statistically significant differences were observed among the pseudo-germ-free model group, the pseudo-germ-free QWD group, and the pseudo-germ-free mesalazine group (P>0.05). ConclusionQWD may promote the reconstruction of the intestinal mucus barrier by regulating the intestinal flora, thereby exerting a therapeutic effect on acute UC.

OBJECTIVE To investigate the mechanism of Xibining Ⅱ formula in alleviating synovial inflammation and fibrosis in knee osteoarthritis (KOA) rats based on Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) pathway. METHODS Seventy-five male SD rats were randomly divided into sham operation group (Sham group), KOA group, Xibining Ⅱ low-dose group (XBNⅡ-L group, 4 g/kg), Xibining Ⅱ high-dose group (XBNⅡ-H group, 8 g/kg), and Xibining Ⅱ high-dose combined with STAT3 activator Colivelin trifluoroacetate (C-TFA) group [C-TFA group, 8 g/kg Xibining Ⅱ+ 1.0 mg/(kg·d) C-TFA], with 15 rats in each group. Except for the Sham group, the KOA model was established by anterior cruciate ligament transection in the other groups. After successful modeling, each group was given corresponding drugs by intragastric administration and (or) intraperitoneal injection once daily for 28 consecutive days. After the last medication, the pathological changes of synovial tissue of knee joint in each group were evaluated and the indicators were calculated. The levels of serum inflammatory factors were detected. The positive expressions of phosphorylated JAK2 (p-JAK2) and phosphorylated STAT3 (p-STAT3) in synovial tissue of the knee joint were detected. The expressions of JAK2/STAT3 pathway-related proteins and mRNAs in synovial tissue were detected. RESULTS Compared with the Sham group, the synovial lining cells in the KOA group showed significant proliferation and disordered arrangement; the Krenn score, fibrosis ratio, positive area percentage of p-JAK2 and p-STAT3, p-JAK2/JAK2 and p-STAT3/STAT3, protein expression of Collagen-Ⅰ and α -smooth muscle actin, the mRNA expression of JAK2, STAT3, Collagen-Ⅰ and α -smooth muscle actin, as well as serum levels of interleukin-1β and interleukin-18 were significantly increased ( P <0.05). Compared with the KOA group, the above pathological changes were significantly improved in each dose group of Xibining Ⅱ formula, and all indicators were significantly decreased ( P <0.05), with the XBNⅡ-H group showing better effects than the XBNⅡ-L group ( P <0.05). Compared with the XBNⅡ-H group, the above pathological damages were aggravated in the C-TFA group, and all indicators were significantly worsened ( P <0.05). CONCLUSIONS Xibining Ⅱ formula can alleviate synovial inflammation and fibrosis in KOA rats, and its mechanism may be related to inhibiting the activation of JAK2/STAT3 pathway.

Autosomal dominant polycystic kidney disease (ADPKD) is a systemic hereditary renal disorder and can affect multiple organs, and congenital hepatic fibrosis is one of the manifestations of liver involvement and is an important complication of ADPKD. Symptomatic management is currently the main treatment method for this disease, and disease-specific drugs such as tolvaptan have limited indications and cannot correct the underlying genetic defect. This article reports a case of ADPKD with congenital hepatic fibrosis, and sirolimus was identified as the individualized treatment regimen based on peripheral blood functional genomic analysis and drug sensitivity prediction platform. The patient achieved significant improvements in symptoms and quality of life after treatment, with a stable kidney volume. This case shows that functional genomics has a potential value in guiding individualized treatment of rare genetic disorders, which provides new treatment ideas and practice paths for similar patients.
