Objective: To explore the distribution of traditional Chinese medicine (TCM) syndromes in children with hepatolenticular degeneration (Wilson disease, WD) based on factor analysis and cluster analysis. Methods: From November 2018 to November 2023, general information (gender, age of admission, age of onset, course of disease, clinical staging, Western medicine clinical symptoms, and family history) and TCM four-examination informations (symptoms and signs) were retrospectively collected from 757 cases of children with WD at the First Affiliated Hospital of Anhui University of Chinese Medicine, and factor analysis and cluster analysis were used to investigate TCM syndromes in children with WD. Results: A total of 757 children with WD were included, of which 483 were male and 274 were female; the median age at admission was 12.58 years, the median age at onset was 8.33 years, and the median course of disease was 24.37 months; clinical typing result indicated 506 cases of hepatic type, 133 cases of brain type, 99 cases of mixed-type, and 19 cases of other type; 36.46% of the children had no clinical symptoms (elevated aminotransferases or abnormalities in copper biochemistry); a total of 177 cases had a definite family history, and 10 cases had a suspected family history. Forty-three TCM four-examination information were obtained, with the top 10 in descending order being feeling listless and weak, brown urine, slow action, inappetence, dim complexion, slurred speech, angular salivation, body weight loss, hand and foot tremors, and abdominal fullness. In children with WD, the syndrome element of disease location was primarily characterized by the liver, involving the spleen and kidney, and the syndrome elements of disease nature were characterized by dampness, heat, and yin deficiency. Based on factor analysis and cluster analysis, five TCM syndromes were derived, which were, in order, syndrome of dampness-heat accumulation (265 cases, 35.01%), syndrome of yin deficiency of the liver and kidney (202 cases, 26.68%), syndrome of liver hyperactivity with spleen deficiency (185 cases, 24.44%), syndrome of qi and blood deficiency (79 cases, 10.44%), and syndrome of yang deficiency of the spleen and kidney (26 cases, 3.43%). Conclusion The TCM syndromes of children with WD were primarily syndromes of dampness-heat accumulation, yin deficiency of the liver and kidney, and liver hyperactivity with spleen deficiency. The liver was the main disease location, and the disease nature was characterized by deficiency in origin and excess in superficiality, excess and deficiency mixed. These findings suggest that treating children with WD should be based on the liver while also considering the spleen and kidney.

Autism spectrum disorder in children (hereinafter called "childhood autism") is a prevalent neurodevelopmental condition; however, ancient Chinese medical texts did not provide detailed accounts of it. The concept of "the sovereign fire illuminates, while the ministerial fire occupies its position" was first introduced in the Plain Questions: The Great Treatise on the Origin of Heavenly Influences chapter. Subsequent medical practitioners have elaborated on this idea, identifying the sovereign fire as the master of the spirit and governing life activities, while the ministerial fire is the assisting minister that supports the functions of the zang-fu organs. When these two are in harmony, they complement each other, collectively sustaining the body′s normal physiological functions. In the context of this theory, the pathogenesis of childhood autism is attributed to the imbalance between the sovereign and ministerial fires. The root cause lies in the mutual antagonism of these two fires, resulting in the dysfunction of the spirit. Central to childhood autism onset is the dimming of the sovereign fire and a deficiency in the spirit, while the displacement of the ministerial fire and the impaired function of the five viscera contribute significantly to the progression of the condition. Effective treatment for childhood autism involves restoring these imbalances: dispelling yin-related obstructions to illuminate the sovereign fire, nourishing the spleen and kidney to nourish the ministerial fire, and regulating the liver and lung to harmonize the sovereign and ministerial fires. The ultimate goal is to integrate body and spirit, harmonize the sovereign and ministerial fires, and restore the interconnectedness between spirit and the function of the five zang viscera. This article, based on the "the sovereign fire illuminates, while the ministerial fire occupies its position" theory, provides a novel perspective and insights for understanding and treating childhood autism through the holistic principles of traditional Chinese medicine. Emphasizing the integration of body and spirit offers new insights and approaches for the clinical management of childhood autism in traditional Chinese medicine.

The lung collaterals form a network that branches from the lung meridian, traversing the lung system and extending across the body′s surface. Lung collateral disease refers to the structural alterations or dysfunction in these collaterals caused by external or internal pathogens. Research into the structural and physiological functions of children′s lung collaterals, as well as the pathogenesis and syndrome differentiation for treating lung collateral diseases in children, holds significant value in guiding the prevention and treatment of pediatric respiratory conditions. Drawing on the theory of collateral disease, the clinical insights of both historical and contemporary physicians, and modern research findings—while considering the unique physiological and pathological characteristics of children′s respiratory systems—this study provides a foundational summary of the morphology and spatial distribution of children′s lung collaterals. The characteristics of these collaterals are highlighted as thin, sparse, short, narrow, brittle, and tender. From this structural understanding, the unique physiological functions of children′s lung collaterals are analyzed. The study further explores the interactions between pathogenic factors and lung collaterals, elucidating the pathogenesis and progression of children′s lung collateral diseases. It proposes treatment principles centered on "seeking treatment in the collaterals and employing the method of unblocking collaterals, "which align with the unique features of pediatric lung collaterals. Common treatment approaches, and relevant prescriptions for managing these diseases are summarized. This paper lays the foundation for a theoretical system encompassing the structure, function, pathogenesis, and syndrome differentiation for treating children′s lung collateral diseases. It offers valuable insights for the clinical diagnosis and management of pediatric respiratory diseases linked to collateral dysfunction and serves as a reference for the systematic development of a broader theoretical framework for children′s collateral diseases.

Multiple system atrophy (MSA) is a rare neurodegenerative disease with complex clinical manifestations, presenting substantial challenges in clinical diagnosis and treatment. Its symptoms and the eight extraordinary meridians are potentially correlated; therefore, this article explores the association between MSA symptom clusters and the eight extraordinary meridians based on their circulation and physiological functions, as well as their treatment strategies. The progression from deficiency to damage in the eight extraordinary meridians aligns with the core pathogenesis of MSA, which is characterized by "the continuous accumulation of impacts from the vital qi deficiency leading to eventual damage". Liver and kidney deficiency and the emptiness of the eight extraordinary meridians are required for the onset of MSA; the stagnation of qi deficiency and the gradual damage to the eight extraordinary meridians are the key stages in the prolonged progression of MSA. The disease often begins with the involvement of the yin and yang qiao mai, governor vessel, thoroughfare vessel, and conception vessel before progressing to multiple meridian involvements, ultimately affecting all eight extraordinary meridians simultaneously. The treatment approach emphasizes that "the direct method may be used for joining battle, but indirect method will be needed in order to secure victory" and focuses on "eliminate pathogenic factors and reinforce healthy qi". Distinguishing the extraordinary meridians and focusing on the primary symptoms are pivotal to improving efficacy. Clinical treatment is aimed at the target, and tailored treatment based on careful clinical observation ensures precision in targeting the disease using the eight extraordinary meridians as the framework and core symptoms as the specific focus. Additionally, combining acupuncture, daoyin therapy, and other method may help prolong survival. This article classifies clinical manifestations based on the theory of the eight extraordinary meridians and explores treatment.

Objective: To analyze the relationship between microorganisms and endodontic disease by using 16 S rDNA sequencing to compare the composition of the microbial community in the root canals of teeth with pulpitis and apical periodontitis. Methods: Clinical samples were collected from teeth requiring root canal treatment.The total DNA of the bacteria in the samples and the gene fragments of the V3-V4 highly variable region on the 16S rDNA fragments were amplified through PCR.After sequencing by NovaSeq,statistical and bioinformatic analysis,including phylogenetic analysis,diversity analysis and analysis of group differences,were performed. Results: In total,6 teeth with pulpitis and 7 teeth with apical periodontitis were collected,and a total of 8 510 OTUs were obtained after next-generation sequencing,and the analysis of bacterial diversity showed that the difference between pulpitis and apical periodontitis in terms of the composition of the bacterial flora was statistically significant(P<0.05).In particular,the relative abundance of Proteobacteria,Acidobacteriota and Actinobacteriota phylum was significantly higher in the roots of teeth affected by pulpitis than apical periodontitis.The relative abundance of Bacteroidota phylum and Synergistota phylum was significantly higher in the root canals of teeth with apical periodontitis. Conclusion There is a complex diversity of infecting microorganisms in the root canals of teeth affected by endodontic diseases.The microbial communities in the infected root canals of pulpitis and apical periodontitis show some differences,and changes in the microbial composition of the root canals may be associated with the development of endodontic diseases.

Objective: To investigate the differences in enolase and laminin levels in vaginal epithelial tissues between mice successfully infected withGardnerellaand mice not infected with Gardnerella, providing information for further exploration of the correlation between enolase and laminin levels and the incidence of bacterial vaginosis. Methods: Gardnerella strains isolated, purified, and identified from vaginal secretions of patients with bacterial vaginosis were used to infect the vagina of mice and establish a mouse model of bacterial vaginosis. Successful and failed mice was defined as successful and failed groups, respectively. Differential expression of enolase and laminin in the vaginal epithelial tissue of two groups of mice was detected by Western blot. Modeling success rate was statistically analyzed, and the expression differences of enolase and laminin was compared between two groups. Results: One strain of Gardnerella vaginalis infected 10 SPF grade KM mice, 7 mice met the diagnostic criteria for bacterial vaginosis, and 3 mice failed to model, with a success rate of 70%. Western blot was used to detect protein expression levels, and the levels of laminin and enolase in the successfully modeled mouse vaginal epithelial tissue were significantly higher than those in the failed modeling group, with statistical differences between the two groups(P<0.05). Conclusion Enolase and laminin may be involved in the occurrence of bacterial vaginosis, however, further research is needed to determine the mechanisms through which they trigger the occurrence and development of the disease.

This article employs a multidisciplinary approach encompassing traditional Chinese medicine, history, philology, and exegetics to comprehensively examine the historical evolution of auricular acupoint therapy and otomedicine. Originating in China, systematized in Europe, and currently advancing through modern research and development led by China, this study traces the historical context of otological practices. It outlines the foundational principles of otomedicine as depicted in the Huangdi Neijing, elucidates the accumulation of ancient otomedical knowledge within this framework, reviews the systematic establishment and theoretical underpinnings of auricular acupoints, and delineates the process of formulating auricular acupoint standards. Through case studies such as " ear-brain interconnection" and " ear treatment of encephalopathy", it illustrates the interdisciplinary nature of ear medicine research and development. The article aims to illuminate the historical transition from ear therapy to ear medicine within the contemporary context and the emergence of auricular point-guided ear medicine. By drawing on historical insights and looking toward the future, it provides a foundation for the ongoing development of the ear medical specialty, offering insights for integrating non-drug therapies into China&prime;s healthcare system and global health initiatives.

Glycyrrhizae Radix et Rhizoma is the most commonly used herb in ZHANG Zhongjing&prime;s Treatise on Cold Pathogenic Diseases and Synopsis of Golden Chamber. It serves as a crucial entry point for understanding ZHANG Zhongjing&prime;s prescription system. The role of Glycyrrhizae Radix et Rhizoma in ZHANG Zhongjing&prime;s prescription system differs from its current recognized efficacy. By analyzing the typhoid prescriptions and referring to ancient materia medica texts from various dynasties, this study categorizes the formulas containing Glycyrrhizae Radix et Rhizoma and identifies four fundamental efficacies associated with it: fluid retention, preservation of gastric qi, support of yang qi, and protection of the triple energizer. These basic efficacy principles align with the core treatment principles implied in ZHANG Zhongjing&prime;s prescription system, suggesting that Glycyrrhizae Radix et Rhizoma is one of the key herbs in constructing ZHANG Zhongjing&prime;s prescription system. To elucidate the logical expansion of prescriptions, formulas containing Glycyrrhizae Radix et Rhizoma are deconstructed and classified into first-order, second-order, tertiary-order, quaternary-order, and other formulas based on the affinity of the paired herbs. Similarly, the corresponding herbs are classified accordingly. Using Cinnamomi Ramulus, Zingiberis Rhizoma, Paeonia lactiflora Pall., and Ephedrae Herba as examples, the study analyzes the principles behind formulas containing Glycyrrhizae Radix et Rhizoma. ZHANG Zhongjing&prime;s prescription system strategically added or subtracted other herbs to fully utilize or extend the four fundamental effects of Glycyrrhizae Radix et Rhizoma, resulting in the majority of existing formulas through continuous expansion. This provides new insights and approaches for further in-depth study of ZHANG Zhongjing&prime;s prescription system.
