ObjectiveTaking Aurantii Fructus Immaturus juice(AFI)-processed Atractylodis Macrocephalae Rhizoma(AMR) as an example, this study aims to systematically compare the volatile and non-volatile components of AMR and its processed products, investigate the key differential components, evaluate their anti-inflammatory activities, and elucidate the synergistic mechanism of processing. MethodsThe chemical compositions of volatile and non-volatile components in AMR and AFI-processed AMR were systematically characterized using gas chromatography-mass spectrometry(GC-MS) and ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS), with relative mass fractions and response values determined separately. Volatile components were identified through searches in the National Institute of Standards and Technology(NIST)17 database, comparison with retention index(RI) and fragmentation pattern matching. Non-volatile components were identified by searching Waters Traditional Chinese Medicine (TCM) spectral library, in conjunction with PubChem and MassBank, characteristic fragmentation patterns and response values were also used to support identification. Differential components were screened using principal component analysis(PCA), orthogonal partial least squares-discriminant analysis(OPLS-DA), with variable importance in the projection(VIP) value >1. Components with high log2fold change(FC) among major differential groups were selected as those exhibiting significant changes before and after processing. The anti-inflammatory activity of the differential compounds was evaluated by assessing their effects on nitric oxide(NO) production in a lipopolysaccharide(LPS)-induced RAW264.7 macrophage model. Enzyme-linked immunosorbent assay(ELISA) was used to detect the effects of the differential components on tumor necrosis factor(TNF)-α, interleukin(IL)-1β, IL-6, and monocyte chemotactic protein(MCP)-1 levels, and immunofluorescence(IF) was employed to assess their effects on nuclear transcription factor(NF)-κB p65 translocation, thereby elucidating the underlying molecular mechanisms. ResultsA total of 36 compounds were identified in the volatile components of AMR and AFI-processed AMR, among which, sesquiterpenes and monoterpenes were significantly increased after processing. In the non-volatile components, 36 compounds were identified, and the main differential components were flavonoids, sesquiterpenoids, and triterpenoids. Flavonoids were the primary differential components distinguishing AMR from its processed products, representing compounds directly introduced during processing. Five compounds, including atractylenolide Ⅲ, tangeritin, nobiletin, hesperidin and narirutin, were selected as representatives of three classes based on their most prominent differential expression among different compound types for subsequent anti-inflammatory activity studies. The results showed that 100 μmol·L-1 tangerine and narirutin could significantly inhibit LPS-induced NO production(P<0.01) in a concentration-dependent manner. Tangeritin was able to significantly inhibit the levels of TNF-α and MCP-1 secreted by RAW264.7(P<0.05), while narirutin significantly inhibited the levels of TNF-α, IL-1β, MCP-1 and IL-6(P<0.01). IF revealed that both tangeritin and narirutin significantly blocked the translocation of NF-κB p65 from the cytoplasm to the nucleus. ConclusionAFI-processed AMR significantly alters the chemical composition profile of AMR, and the newly introduced flavonoid components during processing may be key to its enhanced anti-inflammatory effects.

Employing bibliometric methods and adhering to principles of textual research, this study systematically investigated prescription source, formula name, composition evolution, dose evolution, origin, processing, ancient and modern applications of Xiaofengsan. Xiaofengsan, also known as Renshen Xiaofengsan and Chantui Xiaofengsan, was first recorded in the Taiping Huimin Hejijufang(hereafter referred to as Jufang) of the Southern Song dynasty. The formula composition included Schizonepetae Spica, Glycyrrhizae Radix et Rhizoma, Chuanxiong Rhizoma, Notoptery Rhizoma et Radix, Bombyx Batryticatus, Saposhnikoviae Radix, Poria, Cicadae Periostracum, Pogostemonis Herba, Ginseng Radix et Rhizoma, Magnoliae Officinalis Cortex and Citri Reticulatae Pericarpium, a total of 12 medicinal materials. In terms of the evolution of formula composition, formulas across dynasties largely aligned with those recorded in Jufang, with only minor variations in application. The results of the formula dosage research indicated that one dose of medication in Jufang corresponded to the following modern dosages:Schizonepetae Spica of 82.6 g, Glycyrrhizae Radix et Rhizoma of 82.6 g, Chuanxiong Rhizoma of 82.6 g, Notoptery Rhizoma et Radix of 82.6 g, Bombyx Batryticatus of 82.6 g, Saposhnikoviae Radix of 82.6 g, Poria of 82.6 g, Cicadae Periostracum of 82.6 g, Pogostemonis Herba of 82.6 g, Ginseng Radix et Rhizoma of 82.6 g, Magnoliae Officinalis Cortex of 20.65 g and Citri Reticulatae Pericarpium of 20.65 g, the origins of all the constituent drugs were consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The results of the investigation into the decoction method indicated that the aforementioned drugs should be finely ground into powder(pass through the No.5 sieve), and 8.26 g was taken for each dose, which was taken with the clear liquid obtained by steeping tea leaves in boiling water for several minutes. This mixture was administered three times daily, 30 min after meals. The ancient functional indications of this formula mainly involved dispelling wind-heat, eliminating pathogenic factors and regulating the middle Jiao. It primarily treated all wind-heat syndromes manifesting as skin diseases, predominantly affecting the upper body, especially the head and face. The diseases involved in modern applications were mostly dermatological diseases, including urticaria, eczema, atopic dermatitis and others. In this paper, by combing the relevant ancient literature, the key information of Xiaofengsan was textual researched, in order to provide reference for the modern application and development of this formula.

Natural products have shown great potential in the research and development of antitumor drugs. However, their clinical application is severely limited by inherent drawbacks such as poor water solubility, low stability, and low bioavailability. Cell membrane biomimetic nanoparticles, as a novel drug delivery system, have provided new strategies to overcome this bottleneck. This review systematically summarizes the preparation methods (e.g., membrane extrusion, ultrasonic fusion, and microfluidic electroporation) and characterization techniques (e.g., particle size, Zeta potential, and membrane surface protein detection) of cell membrane biomimetic nanoparticles, with a focus on the application of these derived from various sources in delivering antitumor natural products. Cell membrane biomimetic nanoparticles are endowed with unique biological functions, including low immunogenicity conferred by stem cell membranes, prolonged systemic circulation enabled by red blood cell membranes, and homologous targeting facilitated by tumor cell membranes. Despite these advancements, the technology still faces challenges such as difficulties in large-scale production, high costs, and limited characterization methods. Future research needs to further optimize the relevant processes to promote the clinical translation of cell membrane-biomimetic nanoparticles, thereby offering an efficient and safe novel delivery approach for antitumor therapy using natural products.

Precancerous lesions of gastric cancer (PLGC) are a group of pathological changes caused by abnormalities in the structure, morphology, and differentiation of gastric mucosal epithelial cells. Since the early symptoms are hidden and non-specific, PLGC is not easy to be diagnosed and it has often developed into intermediate or advanced gastric cancer once being diagnosed and missed the best time for treatment. Accordingly, the incidence of this disease is increasing year by year, which lifts a heavy burden on the patients. The pathogenesis of PLGC is complex, involving inflammatory microenvironment, bile reflux, glycolysis, autophagy, and apoptosis. Currently, PLGC is mainly treated with anti-inflammatory and endoscopic therapies, which are difficult to curb the development of PLGC. Therefore, seeking a safe and effective therapy is an important topic of modern research. Traditional Chinese medicine (TCM), characterized by treatment based on syndrome differentiation and a holistic view, exerts effects via multiple pathways, mechanisms, and targets. Recent studies have confirmed that TCM can regulate the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR), Wnt/β-catenin, Sonic Hedgehog, nuclear factor-κB (NF-κB), Janus kinase/signal transducer and activator of transcription (JAK/STAT), hypoxia-inducible factor-1α (HIF-1α), neurogenic locus notch homolog protein (Notch), nuclear factor E2-related factor 2 (Nrf2) and other signaling pathways. By targeting these pathways, TCM can inhibit aerobic glycolysis, reduce oxidative stress, repair the inflammatory microenvironment, regulate cellular autophagy, and promote vascular normalization, thereby delaying or reversing PLGC. However, few researchers have systematically summarized the TCM regulation of PLGC-associated pathways. By reviewing the relevant articles at home and abroad, this paper summarized the roles of the above signaling pathways in the development of PLGC and the research progress in the regulation of signaling pathways by TCM in the treatment of PLGC, with a view to providing a new theoretical basis for the clinical research on PLGC and the drug development for this disease.

[Objective] To extract hemoglobin (Hb) from red blood cells using osmotic pressure swelling method, expected to achieve a hemoglobin dissolution rate of ≥80% and a cell membrane integrity rate of ≥70%. [Methods] Human umbilical cord blood red blood cells were used as raw materials and phosphate buffer solution was used as the swelling solution for red blood cells. A three factor three-level orthogonal experiment (n=3) was conducted to determine the optimal matching conditions for selecting the osmolality molar concentration of phosphate buffer solution, pH value of hypotonic phosphate buffer solution and volume ratio of hypotonic phosphate buffer solution to washed red blood cells. Red blood cell swelling solution samples (n=6) were prepared by the optimal matching conditions and the original process conditions. The hemoglobin dissolution rate and cell membrane integrity rate were checked. In the expanded comparative experiment, red blood cell swelling solution samples (n=6) were prepared by the optimal matching conditions and the original process conditions, which was filtered by ultrafiltration membranes. The filtration time and hemoglobin yield were checked. [Results] The optimal matching conditions for preparing red blood cell swelling solution were obtained through orthogonal experiment as follows: osmotic pressure molar concentration was 30 mOsmol/Kg, pH was 7.8, and phosphate buffer to red blood cell volume ratio was 6∶1. On the basis of the above conditions, the red blood cell swelling solution sample was compared with the original process sample: the hemoglobin dissolution rate was (82.4±1.8)% vs (78.6±3.0)% (P<0.05), and the cell membrane integrity rate was (65.8±4.0)% vs (28.7±2.3)% (P<0.05). In the expanded comparative experiment, the optimal matching conditions were compared with the original process conditions: filtration time(s) (327±9) vs (434±13) (P<0.05), and hemoglobin yield was (72.3±1.2)% vs (66.0±1.4)% (P<0.05). [Conclusion] Compared with the original preparation process, the hemoglobin extraction process which optimized through orthogonal experiments greatly reduces the cell membrane fragmentation rate and minimizes the entry of cell membrane matrix into the target solution, ensuring a slightly higher hemoglobin dissolution rate, and reducing the preparation difficulty for the subsequent cell membrane separation and further purification.

The presence of physiological barriers in the eye (both external and internal) makes conventional ophthalmic medications (eye drops, ointments, gels, etc.) less bioavailable and difficult to reach the posterior segment of the eye. Although intravitreal injection can deliver drugs to the posterior segment of the eye, it has disadvantages such as infection, injury, and poor tolerance. Ophthalmic microneedle breaks through the intra- and extra-ocular barriers, enabling the drug to reach the target site accurately and to be released continuously greatly avoiding intraocular infections and injuries, and improving the bioavailability of the drug, which has obvious advantages as an ophthalmic drug delivery tool. Ophthalmic microneedle can be classified into hollow microneedle, dissolving microneedle, and coated microneedle according to the usage methods. Each type of microneedle has its own advantages and has shown satisfactory performance in the treatment of diseases such as bacterial and fungal keratitis, glaucoma, exudative age-related macular degeneration, diabetic macular edema, non-infectious uveitis, corneal neovascularization, and even choroidal melanoma.

Objective:To evaluate the clinical outcomes of combined complete preservation of chordal structure mitral valve replacement (C-MVR) with total anatomical arterial myocardial revascularization (TACR) in coronary patients with moderate-to-severe or severe ischemic mitral regurgitation (IMR).Methods:This is a retrospective multi-center case series study. Data were retrospectively collected from 127 patients with coronary artery disease with moderate to severe or severe IMR who received TACR with C-MVR from July 2015 to April 2024 in 13 hospitals in China. There were 90 males and 37 females, aged (56.5±10.7) years (range: 33 to 74 years). Perioperative data and follow-up data including left ventricular ejection fraction, left ventricular end-diastolic diameter, and patency rate of arterial grafts of patients were collected. Comparisons were made using paired sample t-test or χ2 test. Results:In this cohort of 127 patients, 67 underwent concurrent tricuspid valve repair. During surgery, 113 grafts of the left internal mammary artery (LIMA), 127 grafts of the left radial artery, 80 grafts of the right radial artery, and 110 grafts of the right internal mammary artery (RIMA) were harvested. The number of the distal anastomosis was 4.2±0.4 (range: 3 to 5). The aortic cross-clamp time and cardiopulmonary bypass time were (97.5±23.4) minutes (range: 90 to 161 minutes) and (145.4±19.2) minutes (range: 101 to 210 minutes), respectively. There was one operative death. Intraoperative placement of an intra-aortic balloon pump was performed in 21 patients to improve the left ventricular ejection. No sternal ischemic occurred. All patients completed follow-up, with a mean follow-up period of (64.3±7.5) months (range: 4 to 110 months). No major cerebrovascular events occurred during the follow-up period, and all patients survived. Left ventricular ejection fraction improved postoperatively (55.0%±5.3% vs. 41.0%±15.3%, t=17.23, P<0.01). The proportion of patients with New York Heart Association functional class ≤2 increased postoperatively (23.6% (30/127) vs. 87.3% (110/126), χ2=103.77, P<0.01). The proportion of patients with Canadian Cardiovascular Society Angina Classification ≤3 decreased postoperatively (4.8% (6/126) vs. 78.7% (100/127), χ2=142.19, P<0.01). The left ventricular end-diastolic diameter decreased postoperatively ((5.70±4.50) cm vs. (6.10±0.23) cm, t=12.15, P<0.01). Coronary multi-detector computed tomography angiography (MDCTA) follow-up was conducted for (60.5±11.7) months (range: 6 to 109 months) postoperatively. MDCTA confirmed the patency rates of the grafts: 96.4% (108/112) for the LIMA grafts, 88.9% (112/126) for the left radial artery grafts, 93.7% (74/79) for the right radial artery grafts, and 90.9% (100/110) for the free RIMA grafts. No significant differences in graft patency rates were observed between the arterial grafts ( χ2=5.24, P=0.155). Conclusion:The results of this multi-centre study demonstrate satisfactory mid-term results of C-MVR with TACR for the treatment of coronary artery disease with moderate to severe or severe IMR.

ObjectiveTo explore effect of Xianlian Jiedu prescription on the recurrence of colorectal cancer (CRC) and investigate the related mechanisms. MethodsA postoperative recurrence model was established in 25 Balb/c mice by injecting CT26 cells subcutaneously into the armpit, followed by surgical removal of 99% of the subcutaneous tumor. The mice were randomly divided into model group, low-dose Xianlian Jiedu prescription (XLJDP-L) group (6.45 g·kg-1·d-1), medium-dose Xianlian Jiedu prescription (XLJDP-M) group (12.9 g·kg-1·d-1), high-dose Xianlian Jiedu prescription (XLJDP-H) group (25.8 g·kg-1·d-1), and 5-fluorouracil (5-FU) group (1×10-3 g·kg-1·d-1). The mice were euthanized after 14 days of continuous intervention, and recurrent tumor tissue was harvested. Hematoxylin and eosin (HE) staining was used to observe pathological and morphological changes in the recurrent tumor tissue. Immunohistochemistry (IHC) was employed to assess the expression of proliferating cell nuclear antigen (Ki67), vascular endothelial growth factor (VEGF), and platelet-endothelial cell adhesion molecule (CD31) in recurrent tumor tissue. The Western blot was used to detect the protein expression levels of angiopoietin-2 (ANG-2), VEGF, phosphorylated-protein kinase B (p-Akt), protein kinase B (Akt), phosphorylated-phosphatidylinositol 3-kinase (p-PI3K), and phosphatidylinositol 3-kinase (PI3K) in recurrent tumor tissue. ResultsBefore treatment, there were no statistical differences in tumor volume, tumor weight, and body mass among the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group compared to the model group, indicating model stability. After treatment, compared with those in the model group, the tumor volume and tumor weight in the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group were significantly reduced (P<0.01), showing dose dependency. Meanwhile, there were no significant differences in body weight among the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group compared to the model group. HE staining showed that compared with that in the model group, tumor tissue in the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group had loosely arranged cells, increased intercellular spaces, small and shriveled nuclei, light staining, fewer mitotic figures and atypical nuclei, and increased necrotic areas. IHC showed that compared with those of the model group, the positive rates of Ki67, VEGF, and CD31 in the recurrent tumor tissue of the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group were significantly reduced (P<0.01) in a dose-dependent manner. Western blot results showed that compared with those of the model group, the protein expression levels of ANG-2 and VEGF in the recurrent tumor tissue of the XLJDP-L, XLJDP-M, and XLJDP-H groups and the 5-FU group were significantly downregulated (P<0.05, P<0.01), and the p-Akt/Akt and p-PI3K/PI3K ratios were significantly decreased in a dose-dependent manner (P<0.05, P<0.01). ConclusionXianlian Jiedu prescription significantly inhibits the recurrence of CRC in mice after subcutaneous tumor surgery. The mechanism may involve regulating the PI3K/Akt pathway and downregulating key angiogenic proteins such as ANG-2, VEGF, and CD31.
