The Sevag deproteinization method was used to purify the crude polysaccharides that were extracted from Shengfupian in the course of this study. Subsequently, the DEAE-52 cellulose chromatography column and Sephadex G-100 co-lumn were employed to isolate the purified neutral polysaccharide fragment. Employing ultraviolet spectroscopy, infrared spectroscopy, ion chromatography, and gel permeation chromatography, the structure of polysaccharides was examined. To determine the anti-inflammatory activity of Shengfupian polysaccharides, an inflammatory response was initiated in RAW2647 cells by administering lipopolysaccharide (LPS). GPR84antagonist8 The study assessed the following factors: the presence of the CD86 antibody on the surface of M1 cells, the role of macrophages, and the quantity of NO and IL-6 present in the supernatant. Based on an immunodepression model developed in H22 tumor-bearing mice, the immunomodulatory activity of Shengfupian polysaccharides was determined through the examination of tumor growth inhibition, immune organ indices, functional assessments, and the quantification of serum cytokine concentrations. Research indicated that Shengfupian polysaccharides (MW 80,251 Da) are formed by arabinose, galactose, glucose, and fructose, in a molar ratio of 0.0004:0.0018:0.0913:0.0065. The scanning electron microscope's perspective showcased a surface exhibiting both smooth and lumpy features. In the concentration spectrum of 25-200 g/mL, Shengfupian polysaccharides exhibited negligible toxicity towards RAW2647 cells. The polysaccharides suppressed the polarization of these cells into the M1 type and diminished the concentrations of NO and IL-6 present within the supernatant. The substance's impact on phagocytosis differed significantly with concentration. At 25 grams per milliliter, it suppressed cellular phagocytosis, but a concentration range of 100-200 grams per milliliter led to enhanced phagocytosis in RAW2647 cells. 200 mg/kg of Shengfupian polysaccharides countered cyclophosphamide-induced spleen damage in mice, leading to augmented serum interleukin-1 and interleukin-6 levels, and reduced tumor necrosis factor-alpha levels. In conclusion, Shengfupian polysaccharides' anti-inflammatory and mild immunomodulatory effects could provide the mechanistic basis for Aconm Lateralis Radix Praeparaia's therapeutic actions in dispelling cold and relieving pain.

The effect of different types of adjuvant rice, including Japonica, millet, yellow, black, and glutinous rice, on the quality of rice-steamed Rehmanniae Radix (RSRR) was investigated in this study, followed by an analysis of the anti-osteoporosis effects using the optimal adjuvant type. Using a standardized UPLC-MS/MS method for catalpol and rehmannioside D quantification, a weighted scoring approach was employed to assess the impact of various auxiliary rice types on the quality of RSRR, using catalpol and rehmannioside D content, character attributes, and taste as evaluation criteria to optimize the choice of adjuvant rice. The rats' ovariectomy procedure resulted in an osteoporosis model. Following a random assignment protocol, SD rats were distributed into a sham operation group, a model group, a positive control group, and low-dose and high-dose treatment groups of Rehmanniae Radix, RSRR, steamed Rehmanniae Radix, and Epimedii Folium-RSRR. After twelve weeks of therapy, body weight, bone calcium content, and bone mineral density were examined. The highest comprehensive RSRR score, achieved using steamed Japonica rice, led to the selection of Japonica rice as the optimal adjuvant, according to the results. Rehmanniae Radix, in its RSRR form, along with steamed Rehmanniae Radix, and Epimedii Folium-RSRR, are plausible candidates for improving osteoporosis by increasing bone calcium content and bone mineral density. RSRR outperformed Rehmanniae Radix in the treatment of osteoporosis. Interestingly, a lack of significant differentiation emerged between RSRR and steamed Rehmanniae Radix. Japo-nica rice was shown in this study to be the optimal adjuvant rice for RSRR, confirming its effectiveness in mitigating osteoporosis and providing a springboard for future investigations into RSRR's pharmacological activities and underlying mechanisms.

The recurrent and intractable nature of ulcerative colitis (UC), an inflammatory bowel disease, demands careful management. Coptidis Rhizoma and Bovis Calculus, historically employed as heat-clearing and toxin-removing remedies, have played a significant role in the treatment of ulcerative colitis. Employing a stimulated co-decoction process, active components berberine (BBR) from Coptidis Rhizoma and ursodeoxycholic acid (UDCA) from Bovis Calculus were integrated to yield UDCA-BBR supramolecular nanoparticles, aiming to augment therapeutic efficacy in ulcerative colitis (UC). Employing field emission scanning electron microscopy (FE-SEM) and dynamic light scattering (DLS), the analysis of supramolecular nanoparticles revealed their tetrahedral nature and an average particle size of 180 nanometers. Through the combined use of ultraviolet, fluorescence, infrared spectroscopy, high-resolution mass spectrometry, and hydrogen-nuclear magnetic resonance (H-NMR) spectroscopy, the molecular structure was characterized. The observed formation of the supramolecular nano-particle was directly linked to the mutual electrostatic attraction and hydrophobic interaction between BBR and UDCA, as shown by the results. Characteristically, supramolecular nanoparticles displayed a sustained release profile and exhibited pH sensitivity. Dextran sulfate sodium (DSS) was used to induce the acute ulcerative colitis (UC) model in mice. Supramolecular nanoparticles were found to be highly effective in reducing body mass and shortening the colon in mice with UC, resulting in a statistically significant decrease in the disease activity index (DAI) (P<0.001). This finding was significant (P<0.0001). The supramolecular nanoparticle and mechanical mixture groups demonstrated statistically significant differences in their characteristics (p<0.0001 and p<0.005). Serum levels of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) were quantified via enzyme-linked immunosorbent assay (ELISA). Results indicated a reduction in TNF-α and IL-6 levels following supramolecular nanoparticle treatment (P<0.0001), demonstrating a statistically significant difference compared to the mechanical mixture group (P<0.001, P<0.005). The effect of supramolecular nanoparticles on neutrophil recruitment to the lamina propria of the colon was observed via flow cytometry, showing a significant reduction (P<0.005) compared to the mechanical mixture group (P<0.005). Analysis of the data revealed that supramolecular nanoparticles outperformed a mechanical mixture in mitigating the symptoms of acute ulcerative colitis in mice. The study proposes innovative research into the problematic absorption of small molecules and the insufficient therapeutic outcomes associated with traditional Chinese medicine, laying the groundwork for future research on nano-drug delivery systems incorporating traditional Chinese medicine.

The springtime rains, from April to June, consistently bring about the emergence of the black spot on Pseudostellaria heterophylla in Zherong County, Fujian Province. The yield and quality of the medicinal material from *P. heterophylla* are greatly affected by black spot, a critical leaf disease. To ascertain the pathogens causing black spot, we initiated the isolation process, categorized them as belonging to the Alternaria species through the Koch's postulates, and then evaluated their pathogenicity and biological attributes. Evidence conclusively points to A. gaisen as the causal agent for the black spot disease in P. heterophylla. This conclusion stems from the consistent similarity in colony morphology, spore characteristics, sporulation patterns, and placement within the same phylogenetic clade with A. gaisen, on a tree constructed from tandem sequences of ITS, tef1, gapdh, endoPG, Alta1, OPA10-2, and KOG1077 genes, supported by a maximum likelihood value of 100% and a Bayesian posterior probability of 100%. The pathogen's mycelial growth achieved its peak performance under conditions of 25°C, pH values ranging from 5 to 8, and 24 hours of darkness. The lethal conditions, comprising a 10-minute treatment at 50 degrees Celsius, were applied to both mycelia and spores. We present here a novel finding of A. gaisen as the source of the black spot on the P. heterophylla plant, reported for the first time. The results might lay a theoretical groundwork for effective methods of controlling and diagnosing P. heterophylla leaf spot diseases.

By analyzing the impact of varying stereoscopic traction heights on the photosynthetic capacity and growth of Codonopsis pilosula, particularly during the middle and late stages of traditional flat planting, this study sought to resolve the issue of stem and leaf shading and determine the ideal traction height for maximizing yield and quality. In this experiment, three stereo-scopic traction heights were implemented: H1 (60 cm), H2 (90 cm), and H3 (120 cm). A control group, labeled CK, consisted of natural growth without traction. The experiment demonstrated that elevating stereoscopic traction heights resulted in a broader growth space for C. pilosula stems and leaves, improving ventilation, significantly increasing the average daily net photosynthetic rate of C. pilosula, promoting the absorption of intercellular CO2, lowering transpiration rates, and mitigating water evaporation.
