ObjectiveThis study aimed to establish a monocrotaline (MCT)-induced pulmonary arterial hypertension (PAH) rat model to systematically evaluate the protective effect of Xiao Qinglongtang (XQLT) on right cardiac function in model rats and further elucidate the underlying regulatory mechanism. MethodsSixty male SD rats were randomly assigned to the normal group, model group, XQLT low-, medium-, and high-dose groups (XQLT-L/M/H), and the beraprost sodium tablet group (BST). Except for the normal group, rats in all other groups were given a single subcutaneous injection of MCT (60 mg·kg-1) to induce PAH. Three weeks after injection, rats in the XQLT-L/M/H groups were administered XQLT intragastrically at 3.07, 6.14, 12.28 g·kg-1·d-1, respectively. Rats in the BST group received beraprost sodium at 12.6 μg·kg-1·d-1, and rats in the model group received an equal volume of saline. All treatments lasted for 3 weeks. Right ventricular systolic pressure (RVSP) was measured by right ventricular catheterization. Cardiac function was assessed by echocardiography. The right ventricle was weighed to calculate the right ventricular hypertrophy index (RVHI). Hematoxylin-eosin (HE) staining, Masson staining, and transmission electron microscopy were used to observe myocardial morphology. Serum metabolomic changes were analyzed using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Data-independent acquisition (DIA) proteomics was used to detect differentially expressed (DE) proteins in the right ventricle, and Western blot was used to measure the expression of uncoupling protein 3 (UCP3), phosphatidylinositol 3-kinase catalytic subunit p110α (PIK3CA), L1 cell adhesion molecule (L1CAM), and quinone oxidoreductase (CRYZ). UPLC-MS/MS was used to analyze the chemical components of XQLT. ResultsCompared with the normal group, the model group showed significantly increased RVSP and RVHI (P<0.05), along with pathological changes in myocardial morphology. Compared with the model group, all XQLT-treated groups exhibited reductions in RVSP and RVHI as well as significant improvements in cardiac function and myocardial morphology. Among the XQLT groups, XQLT-M showed the most pronounced effects (P<0.05), comparable to the BST group. Serum metabolomics revealed 105 differential metabolites in the XQLT groups versus the model group [variable importance in projection (VIP) >1, P<0.05], including 58 upregulated and 47 downregulated metabolites. KEGG enrichment analysis indicated that XQLT intervention downregulated phenylalanine metabolism (P<0.01) and upregulated unsaturated fatty acid biosynthesis (P<0.05). Proteomics analysis showed that 982 DE proteins were identified in the MCT groups versus the normal group, including 455 upregulated and 527 downregulated proteins (|fold change (FC)| >1.3, P<0.05). Compared with the model group, 237 DE proteins were identified in the XQLT groups, including 124 upregulated and 113 downregulated proteins (|FC| >1.3, P<0.05), with 57 overlapping DE proteins. KEGG enrichment suggested that XQLT mainly modulated pathways related to mineral absorption, ribosomal biogenesis, peroxisomes, glycolysis/gluconeogenesis, spliceosomes, and thyroid hormone signaling. Western blot analysis showed that, compared with the model group, XQLT increased the expression of UCP3, PIK3CA, and L1CAM, while decreasing the expression of CRYZ (P<0.05). ConclusionXQLT exerts a protective effect on right heart function in MCT-induced PAH rats, and its mechanism is associated with maintaining myocardial homeostasis and alleviating right ventricular remodeling.

ObjectiveTo investigate the effects of Yueju Wan on the 5-hydroxytryptamine (5-HT) signaling pathway in rats with functional dyspepsia (FD) and to explore its therapeutic mechanism in the treatment of FD. MethodsSixty Sprague-Dawley (SD) rats were randomly divided into a normal group, model group, mosapride group (1.575 mg·kg-1), and Yueju Wan low-, medium-, and high-dose groups (0.735, 1.47, and 2.94 g·kg-1, respectively). The FD rat model was established using GUO's tail-clamping stimulation combined with irregular feeding. After 14 days of modeling, rats were administered the corresponding drugs by gavage for 28 days. After treatment, gastric emptying rate and small intestinal propulsion rate were measured. Serum levels of 5-HT, tryptophan hydroxylase (TPH), and substance P (SP) were detected by enzyme-linked immunosorbent assay (ELISA), and acetylcholine (ACh) levels were determined by chemical methods. Histopathological changes in the gastric antrum were observed using hematoxylin-eosin (HE) staining. Real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot were used to assess the mRNA and protein expression levels of 5-hydroxytryptamine 4 receptor (5-HT4R), SP, and acetylcholinesterase (AChE) in colon tissue, as well as 5-hydroxytryptamine 3 receptor (5-HT3R), SP, and AChE in hypothalamic tissue. Immunohistochemistry (IHC) was used to examine the expression of 5-HT and 5-HT4R in the colon and 5-HT and 5-HT3R in the hypothalamus. ResultsCompared with the normal group, the gastric emptying rate and small intestinal propulsion rate in the model group were significantly decreased (P<0.01). Serum levels of 5-HT, SP, ACh, and TPH were significantly reduced (P<0.01). Histopathological examination revealed irregular arrangement of glands in the gastric antrum, slight mucosal atrophy, and mild inflammatory cell infiltration. The mRNA and protein expression levels of 5-HT4R, SP, and AChE in colon tissue, as well as 5-HT3R, SP, and AChE in hypothalamic tissue, were significantly decreased (P<0.01), and 5-HT protein expression in both the colon and hypothalamus was also significantly reduced (P<0.01). Compared with the model group, all Yueju Wan groups showed significantly increased gastric emptying rate and small intestinal propulsion rate (P<0.01). The glands in the gastric antrum were more regularly arranged, with no inflammatory cell infiltration observed. Serum levels of 5-HT, SP, ACh, and TPH were significantly increased (P<0.01). The mRNA and protein expression levels of 5-HT4R, SP, and AChE in colon tissue and 5-HT3R, SP, and AChE in hypothalamic tissue were significantly upregulated (P<0.05, P<0.01), and 5-HT protein expression in both the colon and hypothalamus was significantly increased (P<0.01). ConclusionYueju Wan has preventive and therapeutic effects on FD, and its mechanism may be related to regulation of the 5-HT signaling pathway, promotion of brain-gut peptide secretion, and enhancement of gastric motility.

ObjectiveTo investigate the mechanism by which Gegen Qinliantang(GQT) improves skeletal muscle insulin resistance. MethodsThe db/m mice were used as the normal group, while db/db mice were assigned to a model group, low-dose (3.12 g·kg-1), medium-dose (6.24 g·kg-1), and high-dose (12.48 g·kg-1) GQT groups, and a Western medicine group (semaglutide, 0.045 mg·kg-1),n=6 in each group. All groups received corresponding interventions. Intraperitoneal glucose tolerance test (IPGTT), intraperitoneal insulin tolerance test (IPITT), and hematoxylin-eosin (HE) staining were used to evaluate insulin resistance and therapeutic efficacy. Serum lipid levels were measured using an automatic biochemical analyzer, and apoptosis in skeletal muscle was assessed via TUNEL assay. Transcriptome sequencing combined with gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses was performed to identify differentially expressed genes (DEGs). Real-time quantitative polymerase chain reaction (Real-time PCR) was used to validate gene expression. Molecular docking was applied to evaluate the binding patterns between active components of GQT and key regulatory genes to elucidate pharmacological mechanisms. ResultsCompared with the model group, the medium-dose and high-dose GQT groups showed significantly reduced fasting blood glucose (FBG) levels (P<0.01). Triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) were markedly decreased (P<0.01), while high-density lipoprotein cholesterol (HDL-C) was significantly increased (P<0.01). IPGTT, IPITT, and HE staining demonstrated that GQT enhanced insulin sensitivity and restored skeletal muscle morphology. GQT also alleviated apoptosis in skeletal muscle tissue. Transcriptome analysis revealed that GQT primarily affected biological processes such as oxidative phosphorylation, metabolic pathways, cellular processes, and protein binding. Real-time PCR results showed that CBR2, CDK6, F830016B08Rik, IL-1β, Rab27b, and COLEC12 were key regulatory genes. Molecular docking demonstrated that CBR2, IL-1β, Rab27b, and COLEC12 formed stable binding with the main active components of GQT. The therapeutic effects of high- and medium-dose GQT were comparable to those of the semaglutide group. ConclusionGQT improves skeletal muscle insulin resistance, potentially by regulating apoptosis as part of its underlying biological mechanism.

ObjectiveTo investigate the mechanism by which Shenqi Yiliu prescription reverses cisplatin resistance in ovarian cancer cells by regulating the phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway-mediated glycolysis. MethodsThe human ovarian cancer A2780 cell line was intervened with progressively increasing doses of cisplatin (1 g·L-1) to establish the cisplatin-resistant cell line A2780cisR, and the cell sensitivity to cisplatin was examined by the cell counting kit-8 (CCK-8) assay. High, medium, and low (39.9, 19.95, 9.98 g·kg-1) doses of Shenqi Yiliu prescription-containing sera were used to treat A2780cisR cells for 48 h. Glucose consumption and lactate production were measured by the cuvette assay. Enzyme-linked immunosorbent assay (ELISA) was employed to determine the activities of glucose transporter (GLUT), phosphofructokinase (PFK), and pyruvate kinase (PK). Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining was used to detect apoptosis. Western blot was employed to quantify the protein levels of phosphorylated (p)-PI3K, p-Akt, p-mTOR, hexokinase 2 (HK2), pyruvate kinase M2 (PKM2), B-cell lymphoblastoma-2 (Bcl-2), Bcl-2-associated X-protein (Bax), and B-lymphoblastoma-2 gene-related promoter (Bad). Real-time PCR was conducted to determine the mRNA levels of HK2, PKM2, Bax, Bcl-2, and Bad. ResultsThe median inhibitory concentration (IC50) of cisplatin on A2780cisR cells was nearly 3 times that on A2780P cells. Compared with A2780P cells, A2780cisR cells showed increased glucose consumption, lactate production, GLUT, PFK, and PK activities, and mRNA and protein levels of p-PI3K, Akt, p-mTOR, HK2, PKM2, Bax (P<0.05), and decreased apoptosis rate and Bcl-2 expression (P<0.05). Compared with A2780cisR cells, medium- and high-dose Shenqi Yiliu prescription reduced the glucose consumption, lactate production, GLUT, PFK, and PK activities, and mRNA and protein levels of p-PI3K, Akt, p-mTOR, HK2, PKM2, Bax, and Bad (P<0.05), while increasing the apoptosis rate and Bcl-2 expression (P<0.05). ConclusionShenqi Yiliu prescription can inhibit glycolysis mediated by the PI3K/Akt/mTOR pathway to promote apoptosis, thereby reversing cisplatin resistance in ovarian cancer cells.

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.

ObjectiveTo observe the clinical efficacy and safety of Yuyin Lidan granules (YYLD) in preventing the recurrence of common bile duct stones (CBDS) in patients with liver and gallbladder dampness-heat syndrome following endoscopic retrograde cholangiopancreatography (ERCP). MethodsThis randomized, parallel, controlled trial enrolled postoperative CBDS-ERCP patients who met the inclusion and exclusion criteria. Sixty-four patients were randomly assigned to an observation group or a control group, with 32 cases in each. Both groups received conventional Western medical treatment after ERCP, while the observation group additionally received YYLD for 8 weeks. The follow-up period lasted for 1 year. The efficacy indicators included bile bilirubin levels, traditional Chinese medicine (TCM) syndrome scores, clinical efficacy rate, pancreatitis and inflammation markers, postoperative liver function, and CBDS recurrence rate at 1-year follow-up, which were used to jointly evaluate the clinical efficacy and safety of both groups. ResultsA total of 56 patients completed the study and were included in the final analysis, i.e., 29 in the observation group and 27 in the control group. Baseline characteristics were comparable between the two groups. Compared with pre-treatment and with the control group after treatment, the bile bilirubin level in the observation group significantly decreased (P<0.05). After treatment, the clinical cure and marked improvement rates were higher in the observation group than in the control group, showing a statistically significant difference in overall clinical efficacy (P<0.05). Compared with pre-treatment, the primary and secondary symptoms in the observation group, as well as the primary symptom and the secondary symptom of nausea and vomiting in the control group (weeks 4 and 8), were significantly reduced (P<0.05). Compared with the control group after treatment, the observation group showed significant reductions in the primary symptom of loose stools/constipation (day 5 and week 4) and in three secondary symptoms, i.e., bitter taste and sticky dry mouth, abdominal distension and poor appetite (throughout the treatment period), and general heaviness and fatigue (day 5 and week 4), with statistical differences (P<0.05). Compared with pre-treatment, both groups showed decreased lipase and urinary amylase levels (P<0.05). However, no significant between-group differences were observed in pancreatitis or inflammation-related indices after treatment. Compared with pre-treatment, all liver function indicators in the observation group and alanine aminotransferase ( ALT ), γ-glutamyl transferase ( γ-GT ), alkaline phosphatase (ALP), and conjugated bilirubin in the control group significantly decreased at weeks 4 and 8 (P<0.05). Compared with the control group after treatment, only serum total bilirubin and unconjugated bilirubin were significantly reduced in the observation group during the treatment period (P<0.05). ConclusionYYLD combined with conventional Western medical treatment can effectively regulate bilirubin metabolism (in bile and serum), improve TCM clinical symptoms, and prevent CBDS recurrence after ERCP in patients with liver and gallbladder dampness-heat syndrome. This regimen is safe and effective and is worthy of further clinical research and promotion.

ObjectiveTo investigate the changes in chemical components of Gardeniae Fructus(GF) before and after being charred, providing data support for research on the material basis of GF Carbonisata(GFC). MethodsUltra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Orbitrap MS/MS) was used to conduct a comprehensive analysis of the chemical components in GF and GFC under positive and negative ion modes with Compound Discoverer 3.3 software and online database. Then, principal component analysis and partial least squares-discriminant analysis in SIMCA14.1 software were used to analyze the MS data of each sample. Based on the principle of variable importance in the projection(VIP) value>1, differential secondary and primary metabolites before and after carbonization were screened. In addition, MetaboAnalyst website was used for pathway enrichment of Kyoto Encyclopedia of Genes and Genomes(KEGG), so as to provide a reference for clarifying the processing mechanism. ResultsA total of 185 components were identified, including 96 secondary metabolites and 89 primary metabolites. These components were classified into nine categories, primarily including iridoid glycosides, flavonoids, and terpenoids, their fragmentation pathways were also analyzed. Simultaneously, multivariate statistical analysis was performed on the secondary and primary metabolites, identifying 70 and 59 differential metabolites, respectively. The secondary metabolites were enriched in two metabolic pathways, including C5-branched dibasic acid metabolism and flavonoid and flavonol biosynthesis, while the primary differential metabolites were enriched in seven pathways such as linoleic acid metabolism and tyrosine metabolism. ConclusionThe chemical components of GF change significantly after carbonization, with a significant decrease in the contents of iridoid glycosides and terpenoids such as hydroxyisogeniposide, crocin Ⅱ, crocetin, and jasminoside B. while the contents of 4-hydroxycoumarin, geniposidic acid, gentiopicroside, and gardenoside methyl ester increase significantly. This change is presumed to be associated with the enhanced cooling and hemostatic effects of the processed products. The identified key components provide a basis for elucidating the material basis underlying the efficacy changes before and after carbonization.

This article systematically reviews and verifies the name, origin, production area, quality evaluation, harvesting, processing and other aspects of Cynanchi Atrati Radix et Rhizoma(CARR) by consulting relevant ancient and modern literature, in order to provide a basis for the development and utilization of famous classical formulas containing this herb. Through textual research, Baiwei has been the official name for CARR, though it also bears alternative names such as Chuncao, Popo Zhenxianbao, Longdan Baiwei. The mainstream base is the roots and rhizomes of Cynanchum atratum. Historical records indicate primary producing areas include Shandong, Anhui, Jiangsu, Shaanxi and Shanxi. Since the late Ming dynasty, varieties from Juxian, Yishui and Rizhao in Shandong have been highly regarded as authentic, commonly known as eastern Baiwei. Since modern times, its quality has been summarized as fine, slender, and straight fibrous roots, pale yellow exterior, whiter interior, and dryness with easy breakability are considered superior. The harvesting time before the Song dynasty was on the third day of the third lunar month, but after the Song dynasty, harvesting was possible in both spring and autumn. The initial processing methods of CARR in ancient times included drying in the shade, removing Lu(the little rhizomes which are on tap of roots), and removing mustaches, modern methods involve washing and sun-drying. During the Northern and Southern dynasties, processing methods included steaming. In the Song dynasty, drying and light stir-frying were predominant, while wine washing emerged in the Ming dynasty. Modern practices primarily involve using raw, stir-frying or honey processing. Regarding the medicinal properties of CARR, both ancient and modern texts agree it has a bitter and salty taste and is non-toxic. Records prior to the Qing dynasty predominantly describe its nature as extremely cold, while mainstream herbal texts after the Qing dynasty generally characterize it as cold. Before the Ming dynasty, there were no records of its meridian tropism. It was not until the Qing dynasty that it was recorded in the lung meridian. Modern records mainly refer to the stomach, liver, and kidney meridians. Throughout history, its main functions have been to clear heat, diuresis, nourish Yin, and replenish essence, primarily treating Yin deficiency and fever syndrome. Based on the research results, it is suggested that when developing famous classical formulas containing CARR, the dried roots and rhizomes of C. atratum can be selected as its medicinal source. If there are no specific processing requirements, raw products can be selected as medicine. If the processing requirements are specified, corresponding processed products can be selected as medicine according to the original formula requirements.

As a distinctive resource of Chinese civilization, traditional Chinese medicine (TCM) technology transfer faces significant opportunities under the background of digital and intelligent transformation, while also being constrained by unique challenges such as the complexity of its theoretical system, lengthy industrial chains, and multidimensional policy restrictions, resulting in a "high-value-high-threshold" paradox. At present, TCM technology transfer is deeply trapped in a "threefold reluctance" dilemma, i.e., unwillingness to transfer, inability to transfer, and lack of capacity to transfer. Specifically, the disconnection between scientific research evaluation systems and market demand leads to low conversion rates of research achievements, unclear ownership and compliance risks suppress innovation incentives, and the absence of professional services intensifies supply-demand mismatches. This article systematically analyzes the specific characteristics of TCM technology transfer and proposes a breakthrough pathway centered on full-chain digital and intelligent transformation. By integrating technologies such as intelligent sorting systems, blockchain-based traceability, and AI diagnostic models, the TCM ecosystem spanning "cultivation-production-service" can be reconstructed. In terms of standardization, promoting the progression from "experience-based data conversion" to "data standardization" and further to "intelligent standardization" is advocated to resolve quality control challenges. For example, a "three-no-one-full" certification system can strengthen quality trust. Policy coordination should focus on optimizing mechanisms for the transformation of scientific and technological achievements, while exploring intellectual property securitization and risk-sharing models to stimulate research momentum. In terms of internationalization, reliance on the Belt and Road Initiative platform to promote the export of geo-authentic medicinal material brands and standards is recommended to build a dual-driven model of "technology plus culture". Looking ahead, through the construction of national-level databases, the cultivation of interdisciplinary talent, and the mutual recognition of international standards, a new paradigm of "scientific intelligent manufacturing" can be formed, providing systematic solutions for the modernization of TCM and global health governance.
