ObjectiveTo investigate the protective effect and mechanism of action of flavonoid combination of Alpiniae Officinarum Rhizoma (A. officinarum) against Helicobacter pylori (H. pylori) gastritis in mice. MethodsAfter acclimatization for one week, 56 SPF-grade healthy C57BL/6J mice were gavaged with mixed antibiotics for three consecutive days. They were randomly divided into a normal group, model group, positive drug group (triple therapy group), and low- and high-dose groups (100, 200 mg·kg-1) of flavonoid combination of A. officinarum. The H. pylori gastritis mice model was established by gavage with H. pylori bacterial suspension in each group except for the normal group. After successful modeling, mice were administrated with corresponding drugs once a day for two weeks. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in gastric tissue. Rapid urease test paper was used to detect the positive rate of H. pylori. Silver staining was used to observe the H. pylori adherence on the surface of gastric tissue. Immunohistochemistry was used to detect the protein expression of interleukin-8 (IL)-8 and myeloid differentiation factor (MyD88) in gastric tissue. The serum levels of IL-6, tumor necrosis factor-α (TNF-α), IL-8, and IL-1β were detected by enzyme-linked immunosorbent assay (ELISA). The expressions of phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) protein were detected by Western blot. ResultsCompared with those in the normal group, mice in the model group had lower gastric weight coefficients, higher pH of gastric juice, 100% H. pylori infection rate, and significantly changed gastric histopathology. The expressions of IL-8 and MyD88 proteins in the gastric tissue of mice in the model group were significantly elevated, and the serum levels of inflammatory factors IL-6, TNF-α, IL-8, and IL-1β were significantly up-regulated in mice. Compared with that in the model group, the gastric weight coefficient of mice in each treatment group of the flavonoid combinations of A. officinarum was elevated (P<0.01), and the pH of gastric juice was reduced (P<0.01). The infection rate of H. pylori was reduced. The expressions of IL-8 and MyD88 proteins in the gastric tissue of mice in the treatment groups were significantly reduced (P<0.01), and the serum levels of inflammatory factors IL-6, TNF-α, IL-8, and IL-1β were significantly reduced in a dose-dependent manner (P<0.01). The flavonoid combinations of A. officinarum down-regulated the expression of PI3K and Akt proteins in H. pylori gastritis-infected cells (P<0.01). ConclusionThe protective effect of flavonoid combinations of A. officinarum against H. pylori gastritis is associated with the inhibition of H. pylori infection rate and regulation of PI3K/Akt signaling pathway, resulting in inhibiting the release of inflammatory factors.

This article systematically analyzes the historical evolution of the name, medicinal parts, origin, harvesting, processing and other aspects of Houttuyniae Herba(HH) by referring to the medical books, prescription books and other documents of the past dynasties, combined with the research materials related to modern and contemporary times, in order to provide a basis for the development of famous classical formulas containing this herb. In ancient literature, HH was often referred to as "Ji" and "Jicai", the name of "Ji" was first recorded in Mingyi Bielu during the Han and Wei dynasties, and the name of Yuxingcao was first seen in Lyuchanyan Bencao during the southern Song dynasty and has continued to this day. The origin of HH used throughout history is consistent, all of which are the whole herb or aboveground parts of Houttuynia cordata in Saururaceae family. HH recorded throughout history has a wide range of production areas, mostly self-produced self-marketing. In ancient times, fresh HH was often used as medicine by pounding its juice without involving any processing steps. Both fresh and dried products can be used as medicine, the fresh products uses the whole plant, while the dried products uses the aboveground parts, which are cleaned, selected and processed before use. Fresh products are harvested regardless of season, while dried products are harvested in both summer and autumn, with summer as the best. In ancient times, there were no specific requirements for the quality of HH, while in modern times, "intact stems and leaves with a strong fishy smell" are preferred. In addition, the medicinal properties of HH have undergone significant changes from ancient to modern times. In the early period, it was believed that its medicinal property was slightly warm, until the 1977 edition of Chinese Pharmacopoeia officially changed it to slightly cold. Both ancient and modern literature states that HH can be used for the treatment of carbuncle and malignant sores, Lyuchanyan Bencao for the first time introduced HH fresh juice can relieve summer heat, since Diannan Bencao recorded that it can be used for lung carbuncle, and gradually developed into the first choice for the treatment of lung carbuncle. Based on the research results, it is suggested that fresh herb or dried aboveground parts of H. cordata are used as medicine when developing famous classical formulas.

Aquatic organisms can secrete biomacromolecules through specialized organs, tissues, or structures, enabling adhesion to underwater material surfaces and leading to severe biofouling issues. This phenomenon adversely impacts aquatic ecosystem health and human activities. Biofouling has emerged as an emerging global environmental challenge. Adhesion serves as the foundation of biofouling, representing a critical step toward a comprehensive understanding of the adhesion mechanisms of aquatic organisms. Biomacromolecules, including proteins, lipids, and carbohydrates, are the primary functional components in the adhesive substances of aquatic fouling organisms. Research indicates that these biomacromolecules exhibit diversity in types and characteristics across different aquatic organisms, yet their adhesion mechanisms show unifying features. Despite significant progress, there remains a lack of comprehensive reviews on the adhesion mechanisms mediated by biomacromolecules in aquatic fouling organisms, particularly on the roles of lipids and carbohydrates. Through a comprehensive analysis of existing literature, this review systematically summarizes the mechanistic roles of three classes of macromolecules in aquatic biofouling adhesion processes. Proteins demonstrate central functionality in interfacial adhesion and cohesion through specialized functional amino acids, conserved structural domains, and post-translational modifications. Lipids enhance structural stability via hydrophobic barrier formation and antioxidative protection mechanisms. Carbohydrates contribute to adhesion persistence through cohesive reinforcement and enzymatic resistance of adhesive matrices. Building upon these mechanisms, this review proposes four prospective research directions: optimization of protein-mediated adhesion functionality, elucidation of lipid participation in adhesion dynamics, systematic characterization of carbohydrate adhesion modalities, and investigation of macromolecular synergy in composite adhesive systems. The synthesized knowledge provides critical insights into underwater adhesion mechanisms of aquatic fouling organisms and establishes a theoretical foundation for developing mechanism-driven antifouling strategies. This work advances fundamental understanding of bioadhesion phenomena while offering practical guidance for next-generation antifouling technology development.

ObjectiveThis study aims to investigate the inhibitory effect of Wutoutang on pannus formation in adjuvant-induced arthritis (AIA) rats with wind-cold-dampness Bi syndrome and its potential mechanism. MethodA total of 40 male SD specific pathogen-free (SPF) rats were selected and divided into blank group, wind-cold-dampness Bi syndrome group [Complete Freund's Adjuvant (CFA), 200 μg], Wutoutang group (15 g·kg-1·d-1), and indometacin group (10 mg·kg-1) according to random number table method. Except for the blank group, the other groups were given wind-cold-dampness stimulation before the CFA injection. After the rats were administered for 30 days, the basic conditions, onset time, arthritis index score, and foot swelling volume of AIA rats with wind-cold-dampness Bi syndrome were observed. Finally, peripheral arterial blood, ankle joint, and synovial tissue were taken. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor A (VEGFA) protein content, and rheumatism, including anti-O (ASO), C-reactive protein (CRP), and rheumatoid factor (RF). Hematoxylin-eosin (HE) staining revealed the changes in joint histomorphology. Immunohistochemistry was used to detect the expression of HIF-1α and VEGFA, two important proteins in the ankle pathway. Quantitative real-time polymerase chain reaction (Real-time PCR) was used to reveal mRNA levels of HIF-1α, VEGFA, angiopoietin-1 (Ang-1), and angiopoietin-2 (Ang-2) in rat synovial tissue. ResultThe foot swelling volume and arthritis score of AIA rats with wind-cold-dampness Bi syndrome were substantially higher (P<0.01) compared with the blank group. Serum CRP, RF, and ASO levels were considerably elevated (P<0.01). HE staining showed obvious hyperplasia of ankle synovium and synovial inflammation, angiogenesis and pannus formation, and aggravated bone destruction, indicating successful modeling. After the intervention of Wutoutang, the onset time was delayed (P<0.01). Foot swelling volume and arthritis score were decreased (P<0.01). Serum CRP, RF, and ASO levels were significantly decreased (P<0.01). The inflammatory hyperplasia of synovial tissue, angiogenesis and pannus formation, and bone destruction were alleviated. The mRNA levels of HIF-1α, VEGFA, Ang-1, and Ang-2 in the synovial membrane were significantly decreased (P<0.05, P<0.01). The expressions of HIF-1α and VEGFA in serum and ankle joints were decreased (P<0.01). In the indomethacin group, the onset time of the disease was delayed (P<0.01). Foot swelling volume and arthritis score were decreased (P<0.01). Serum CRP, RF, and ASO levels were significantly decreased (P<0.01). HIF-1α/VEGFA/Ang signaling pathway was activated, and pathological tissue injury was improved. ConclusionWutoutang can delay the onset time of AIA rats with wind-cold-dampness Bi syndrome, reduce foot swelling volume, arthritis score, rheumatic activity, and improve joint histopathology. It can inhibit pannus formation, and its mechanism may be related to down-regulating the expression of the HIF-1α/VEGFA/Ang pathway.

By reviewing the ancient and modern literature, the name, origin, scientific name evolution, place of origin, quality, harvesting, processing, efficacy and toxicity of Asteris Radix et Rhizoma(ARR) were systematically sorted out, so as to provide reference for the development and utilization of the relevant famous classical formulas. According to textual research, ARR was first contained in Shennong Bencaojing, all generations are Ziwan for its proper name, and there are still aliases such as Ziyuan, Ziqian and Xiaobianer. Its mainstream origin in successive generations was Aster tataricus, and there are also Ligularia fischeri and others in local area of use. The medicinal parts of ARR are root and rhizome, but in modern times, the rhizome is mostly used for propagation and cultivation, so some of ARR medicinal materials only have the root without the rhizome. The earliest recorded ancient origin of ARR was now Fangxian(Hubei), Zhengding and Handan(Heibei), then the range of production areas gradually expanded, the mainstream production areas from the Song dynasty to the Ming and Qing dynasties included Hebei, Jiangsu, Anhui, Henan and other places, since modern times, two major producing areas have been formed in Anguo, Hebei province and Bozhou, Anhui province. From the quality evaluation, it is clear that from ancient times, flexible roots and purple color are the best. The ancient harvesting was mainly in lunar February or March, and then dried in the shade, and the modern harvesting is mostly in spring and autumn, and the roots are braided into pigtails and then dried in the sun or dried in the sun after 1-2 d. The ancient and modern processing method of ARR are basically the same, mainly honey processing, there are still methods of frying, steaming, vinegar sizzling, etc. Based on the results, it is recommended that the dried roots and rhizomes of A. tataricus should be used in clinical and the development of related famous classical formulas, and those whose original formulas specify the processing requirements can be processed according to the relevant requirements, while whose processing requirements are not specified should be used in the form of raw products.
