Objective:To analyze and clarify the meaning of the concept of self-advocacy among patients with chronic diseases using the Rodgers evolutionary concept analysis method.Methods:A systematic search was conducted in databases including PubMed, Web of Science, Cochrane Library, CINAHL, Embase, Medline, VIP, Wanfang, the China National Knowledge Infrastructure, and Chinese Biomedical Literature Database for studies related to self-advocacy in chronic disease patients from February 1, 1992, to June 30, 2024. The Rodgers evolutionary concept analysis method was applied to analyze the selected literature.Results:A total of 72 articles were included in this study. The concept attributes of self-advocacy in chronic disease patients were identified as cognitive awareness, self-action, and resource integration. The antecedents involved included personal characteristics, skill learning, and available support. The outcomes covered improved symptom management, adherence to treatment plans, enhanced nursing and quality of life, and reduced demand for healthcare. The measurement tools used were the Patient Self-Advocacy Scale, Self-Advocacy Scale, Elderly Safety Advocacy Empowerment Scale, and Female Cancer Patient Self-Advocacy Scale.Conclusions:The conceptual attributes of self-advocacy in chronic disease patients were clarified through the Rodgers evolutionary concept analysis method. Future research can combine quantitative and qualitative studies to further explore the significance of self-advocacy in patients with chronic diseases.

ObjectiveBased on the experience of traditional quality evaluation， the quality of Atractylodis Macrocephalae Rhizoma（AMR） with different production methods such as direct seeding， transplanting after seedling raising， topping and non-topping， and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining， and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides， oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography（UPLC）， and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA）. ResultIn terms of traits， the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck， strong sweetness and clear aroma" recorded in ancient materia medica， followed by the 3-year-old AMR with topping after transplanting， while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect， the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang， the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition， the contents of 70% ethanol extract， fructose， glucose， sucrose， 1-kestose， atractylenolide Ⅰ， chlorogenic acid， neochlorogenic acid， cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples（P<0.05）. The contents of cellulose， 70% ethanol extract， sucrose， atractylenolide Ⅰ， atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate（P<0.05）， while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting， direct seeding and without topping（P<0.05）. ConclusionUnder the current mainstream production mode， too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield， but the accumulation of sweet substances， fragrant substances and fiber substances is insufficient， which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it， it is suggested to revise the quality standard of AMR， supplement the quantitative analysis of secondary metabolites， and strengthen the production of imitation wild AMR.

Hyaluronic acid is widely used in biomaterials, cosmetics, clinical medicine and other fields due to its good biocompatibility, degradability, hydrophilicity, tumor targeting, viscosity and other characteristics. Pharmacodynamic activities of natural small molecular products which derived from traditional Chinese medicine (TCM) are significant, but their low solubility and poor targeting limit the clinical application. Based on supramolecular properties of hyaluronic acid, in this review, numerous studies were reviewed on the improvement of solubility, bioavailability, targeting and suitable dosage forms of small molecular compounds in TCM by domestic and foreign scholars using hyaluronic acid as carrier. It provides new ideas and inspirations for exploring the potential application value of small molecule compounds in TCM and even for the research and development of new drugs.

Objective::To investigate the correlation between the characteristics and internal quality of Ophiopogonis Radix from Sichuan province through various quality evaluation, and provide reference for the formulation of grading standard of this herb. Method::For 28 batches of Ophiopogonis Radix, the characters, microscopic characteristics, thin-layer chromatography (TLC), the content of moisture, ash content, acid insoluble ash content, residues of sulfur dioxide, heavy metals, hazardous elements and paclobutrazol, water-soluble extract, contents of total saponins and three major components [ophiopogonin D (OPD), methylophiopogonanone A (MPOA) and methylophiopogonanone B (MPOB)] were determined.The relationships between various indicators and the grade of Ophiopogonis Radix were analyzed. Result::Ophiopogonis Radix exhibited specific properties in characters, microscopic characteristics and TLC.The contents of impurity, moisture, total ash, acid-insoluble ash and water-soluble extract existed differences in four grades of Ophiopogonis Radix from Sichuan province.For grade Ⅰ, grain number was 80-120 grains per 50 g, the moisture content was 11.1%-14.9%, total ash content was 1.6%-2.1%, acid-insoluble ash content was 0.03%-0.14%, water-soluble extract content was 77.0%-86.5%.For grade Ⅱ, grain number was 120-160 grains per 50 g, the moisture content was 13.1%-14.2%, total ash content was 1.3%-2.2%, acid-insoluble ash content was 0.06%-0.22%, water-soluble extract content was 75.9%-83.3%.For grade Ⅲ, grain number was 160-300 grains per 50 g, the impurity was 0.2%-8.4%, the moisture content was 12.6%-14.0%, total ash content was 1.2%-1.5%, acid-insoluble ash content was 0.06%-0.22%, water-soluble extract content was 74.0%-86.5%.For grade Ⅳ, grain number was 80-300 grains per 50 g, impurity was 1.2%-22.6%, the moisture content was 13.0%-15.4%, the total ash content was 1.4%-2.0%, acid-insoluble ash content was 0.03%-0.15%, water-soluble extract content was 79.8%-85.2%. Conclusion::It is reasonable and feasible to classify the grade of Ophiopogonis Radix from Sichuan province according to the appearance characteristics such as the grain number per 50 g and internal indexes such as impurity and water-soluble extract, which can be used as a reference for grading standards of Ophiopogonis Radix from Sichuan province.
