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.

Chronic prostatitis is a common and frequently occurring disease in male clinics. Due to the diverse symptoms, complex etiology, unclear mechanisms, and recurrent episodes of chronic prostatitis, Western medicine often faces the challenge of limited treatment options and unsatisfactory outcomes. In order to fully leverage the unique advantages of traditional Chinese medicine (TCM) in the treatment of chronic prostatitis, the China Association of Chinese Medicine organized a discussion among experts from the fields of TCM urology, Western urology, and related pharmacy. The experts focused on the advancements in the understanding of chronic prostatitis in modern medicine, various theories on the etiology, pathogenesis, and treatment of chronic prostatitis in TCM, entry points from interdisciplinary fields, the role and advantages of TCM in the comprehensive management of chronic prostatitis, and research into mechanisms related to chronic prostatitis. After discussions, the experts concluded that chronic prostatitis is one of the diseases where TCM has a distinct advantage. TCM can effectively improve the clinical syndromes of chronic prostatitis, including urinary issues, social psychology, organ specificity, infection, nervous system problems, pain and discomfort, sexual dysfunction, etc., and can enhance the quality of life. For patients with chronic prostatitis who cannot tolerate or may not accept the adverse effects of Western medicine, as well as for those with non-inflammatory chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), those with pain as the primary symptom, those with urinary tract symptoms, those with coexisting anxiety and depression, and those with abnormal semen liquefaction, TCM-based treatment can be the main approach. Currently, the optimal diagnosis and treatment strategy for chronic prostatitis has not yet been established, and further research from perspectives such as clinical epidemiology, evidence-based medicine, and molecular biology is needed. Both TCM and Western medicine should integrate their respective strengths, clarify the role and advantages of TCM interventions based on mutual reference, and improve the diagnosis and treatment standards for chronic prostatitis in China.

OBJECTIVE:
To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients.
METHODS:
By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup.
RESULTS:
Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens.
CONCLUSIONS
There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.

This article has systematically sorted out and verified the name, origin, producing area, quality evaluation, harvesting and processing of Pruni Semen by consulting ancient materia medica, medical books, prescription books and modern literature, in order to provide a basis for the development of famous classical formulas containing Pruni Semen. The results showed that Pruni Semen, as a medicinal material, has been widely used in medical literature of past dynasties since it was collected in Shennong Bencaojing, and also included under the names such as Yuhe, Yuzi and Yuli, and aliases such as Jueli, Queli and Chexiali. The primordial plants mentioned in the past dynasties involve about 12 species of Rosaceae, but with Prunus humilis, P. japonica and P. glandulosa as mainstream varieties used in the past dynasties, while the 2020 edition of Chinese Pharmacopoeia stipulates that the basal plants are P. humilis, P. japonica and P. pedunculata. Most of the ancient records for the origin of Pruni Semen are found everywhere in high mountains, valleys and hills, modern literature records that its origin varies according to its base, for example, P. humilis and P. japonica are mainly produced in Hebei, eastern Inner Mongolia, Liaoning, Shandong and other regions of China, and P. pedunculata is mainly produced in Inner Mongolia. Modern literature summarizes its quality as faint yellow, full and fulfilling, neat and not broken, and non-oiling, and the small Pruni Semen is better than the big Pruni Semen. The ancient processing methods of Pruni Semen mainly include blanching and peeling, blanching and peeling followed by frying, and blanching and peeling followed by pounding, with the common feature of blanching and peeling. The successive editions of Chinese Pharmacopoeia stipulate that it should be pounded when used. Based on the results of the herbal textual research and the writing time of Bianzhenglu, and combined with the market survey of Pruni Semen, it is suggested that P. humilis or P. japonica should be used as the origin of Pruni Semen in Sanpiantang, and it is harvested when the fruits are ripe, the kernels are collected by removing the stones, and processed by blanching, peeling and pounding consulting the decoction method in the current edition of Chinese Pharmacopoeia.
