ObjectiveTo identify the pathogen species responsible for the wilt disease of Tetradium ruticarpum in Chongqing, investigate there biological characteristics, and screen effective fungicides, so as to provide a theoretical basis for disease control in production. MethodsThe pathogen was isolated via the tissue culture method. Pathogenicity was verified according to Koch's postulates. The pathogen was identified based on morphological characteristics and multi-gene phylogenetic analysis. The mycelial growth rate method was used for biological characterization of the pathogen and fungicide screening. ResultsThe pathogen colonies were nearly circular with irregular edges, white, short, velvety aerial hyphae, and pale purple undersides. Macroconidia were colorless, sickle-shaped, with 3-5 septa, while microconidia were transparent, elliptical, aseptate or with 1-2 septa. Multi-gene phylogenetic analysis showed that the pathogen clustered in the same clade as Fusarium fujikuroi with 100% support, which, combined with morphological characteristics, identified the pathogen causing wilt of T. ruticarpum in Chongqing as F. fujikuroi. The optimal conditions for the mycelial growth of F. fujikuroi were mung bean agar (MBA) with glucose as the carbon source, beef extract and yeast powder as nitrogen sources, 28 ℃, pH 7.0, and alternating light/dark conditions. The optimal conditions for sporulation were potato dextrose agar (PDA) with glucose as the carbon source, beef extract as the nitrogen source, 28 ℃, pH 7.0, and complete darkness. Among chemical fungicides, phenazine-1-carboxylic acid exhibited the strongest inhibitory effect on F. fujikuroi. Shenqinmycin and tetramycin were the most effective bio-fungicides. ConclusionThis study is the first to report F. fujikuroi as the causal agent of wilt disease in T. rutaecarpa. The chemical fungicide phenazine-1-carboxylic acid and the bio-fungicides shenqinmycin and tetramycin showed strong inhibitory effects against F. fujikuroi.

In recent years, hyperuricemia (HUA) has shown a rapidly increasing incidence and tends to occur in increasingly young people, with a wide range of cardiac, renal, joint, and cancerous hazards and all-cause mortality associations. Western medicine treatment has limitations such as large liver and kidney damage, medication restriction, and easy recurrence. The intestine is the major extra-renal excretion pathway for uric acid (UA), and the intestinal microecology can be regulated to promote UA degradation. It offers great potential to develop UA-lowering strategies that target the intestinal microecology, which are promising to provide safer and more effective therapeutic approaches. Traditional Chinese medicine (TCM) can treat HUA via multiple targets and multiple pathways from a holistic view, with low toxicity and side effects. Studies have shown that intestinal microecology is a crucial target for TCM in the treatment of HUA. However, its specific mechanism of action has not been fully elucidated. Focusing on the key role of intestinal microecology in HUA, this review explores the relationship between intestinal microecology and HUA in terms of intestinal flora, intestinal metabolites, intestinal UA transporters, and intestinal barriers. Furthermore, we summarize the research progress in TCM treatment of HUA by targeting the intestinal microecology, with the aim of providing references for the development of TCM intervention strategies for HUA and the direction of future research.

OBJECTIVE To observe the effects of Modified shaoyao gancao decoction on intestinal transit function, intestinal flora and the contents of metabolites [γ aminobutyric acid (GABA) and 5-hydroxytryptamine (5-HT)] in slow transit constipation (STC) rats. METHODS SD rats were randomly divided into blank group (10 rats) and modeling group (30 rats), with half male and half female. The STC model was established by intragastric administration of Compound diphenoxylate tablets in the modeling group. The successfully modeled rats were randomly divided into model group, Modified shaoyao gancao decoction group [56 g/(kg·d), calculated by crude drug] and positive control group [lactulose 2.09 g/(kg·d)], with 10 rats in each group. Each administration group was given relevant medicine intragastrically, the blank group and model group received an equivalent volume of normal saline, once a day, for 14 consecutive days. During the experiment, the general situation of rats was observed in each group. After the last medication, the body weight was measured, and the Bristol score was used to evaluate the fecal characteristics. The fecal moisture content, intestinal propulsion rate, and the contents of GABA and 5-HT in intestinal content were detected; the diversity of intestinal flora in intestinal contents was investigated, and the correlation between the contents of GABA, 5-HT and relative abundance of microbiota was analyzed. RESULTS Compared with the model group, general conditions such as small body shape, sparse and rough fur, and slow movement were all improved in Modified shaoyao gancao decoction body weight, Bristol score, fecal moisture content,intestinal propulsion rate, 5-HT content, Chao1 index and Shannon index were increased significantly, while GABA content and Simpson index were decreased significantly (P<0.05). The intestinal flora of rats in the Modified shaoyao gancao decoction group could be classified as the same as the blank group, but was far from the model group; the relative abundances of Desulfobacterota, Firmicutes and Bacteroidota in this group showed a tendency of pull back, but the differences were not statistically significant compared to model group (P>0.05). Desulfobacterota was an intergroup differential factor (P<0.05). The content of GABA was negatively correlated with the relative abundance of Bacteroidota, Cyanobacteria, Patescibacteria and Actinobacteriota (P<0.05). The content of 5-HT was positively correlated with the relative abundance of Campilobacterota (P<0.05). CONCLUSIONS Modified shaoyao gancao decoction can improve the fecal properties and intestinal motility of STC rats. Its mechanism may be related to improving intestinal flora and then affecting the contents of GABA and 5-HT in intestinal contents. In addition, the contents of GABA and 5-HT may be significantly correlated with the relative abundance of specific bacterial phyla such as Bacteroidota and Campilobacterota.

This study examined the effect of islet macrophages on β-cell function changes during type 2 diabetes mellitus (T2DM) progression based on the traditional Chinese medicine theory that " moderate fire generating qi, hyperactive fire consuming qi" . T2DM is closely associated with chronic low-grade inflammation, with islet macrophages playing a central role in this process. Under physiological conditions, islet macrophages secrete anti-inflammatory and growth factors to regulate the immune response, promote cell proliferation, and support islet β-cell survival and function, reflecting the concept of " moderate fire generating qi" . However, during the pathological process of T2DM, islet macrophages become over-activated and dysfunctional, secreting large amounts of pro-inflammatory factors that trigger severe inflammatory responses and oxidative stress. This process damages islet β-cells, disrupts the islet microenvironment and blood supply, exacerbates local inflammation and structural damage, and worsens the survival environment of β-cells. Ultimately, this leads to fewer β-cells and function loss, aligning with the " hyperactive fire consuming qi" theory, where excessive fire depletes qi and blood. This study enhances the understanding and application of traditional Chinese medicine theories in modern medicine, offering a new perspective on T2DM prevention and treatment. Regulating islet macrophage function and reducing their pro-inflammatory responses may become key strategies for preserving β-cell function and slowing T2DM progression.

From the perspective of dynamic and static concept in traditional Chinese medicine, we explored the pathogenesis and treatment of attention deficit hyperactivity disorder (ADHD). ADHD is categorized into "dynamic type" and "static type" based on symptom presentation. It is believed that the core disease mechanism of static type ADHD refers to insufficiency of essence and blood, as well as the loss of nourishment of brain marrow and heart blood; the dominant mechanism of dynamic type ADHD refers to excessive use of the mind and improper diet lead to the excessive movement of dragon-thunder fire (symbolizing hyperactivity). The treatment should first differentiate between static type and dynamic type. The treatment for static type focuses on the spleen and kidney, and involves replenishing the acquired constitution to nourish the congenital, supporting the heart and spirit, and enriching the brain and marrow, so as to ensure sufficient qi and blood, abundant essence and strong spirit, thereby improving symptoms of attention deficits. The dynamic type should be treated by static method, and involves using calming medicinals to supplement, transform, and subdue to reach the aims of enriching yin and subduing yang, warming and supplementing the spleen and kidney, which helps restore the dragon-thunder fire to its balance. Based on the physiological characteristics of children, a dynamic-static differentiation and treatment system is established to provide a reference for the clinical treatment of ADHD.

As a common pathological state in clinical practice, Chong Mai Wei Bing (冲脉为病) is typically manifested as rebellious qi and a sense of urgency. It often involves various diseases caused by the disorder of qi circulation. From the perspectives of theoretical foundation, pathological characteristics, and clinical differentiation and treatment, this paper elaborates on the characteristics of Chong Mai (冲脉) as the cause of disease, including three main manifestations: upward qi surge, upward yin fire, and upward water-qi. Among these, the upward qi surge is further categorized into four aspects: Chong Qi (冲气) counterflow, counterflow of stomach qi, counterflow of kidney qi, and counterflow of liver qi. Three major treatment methods are proposed: pacifying the Chong Mai and reversing the counterflow, consolidating Chong Mai to subdue fire, and warming Chong Mai to resolve qi and promote water flow. This paper summarizes its practical application in clinical diagnosis and treatment, aiming to deepen the understanding of the functional and pathological mechanisms of Chong Mai, and to provide insights and methods for the traditional Chinese medicine diagnosis and treatment of various diseases.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Electromagnetic fields can regulate the fundamental biological processes involved in bone remodeling. As a non-invasive physical therapy, electromagnetic fields with specific parameters have demonstrated therapeutic effects on bone remodeling diseases, such as fractures and osteoporosis. Electromagnetic fields can be generated by the movement of charged particles or induced by varying currents. Based on whether the strength and direction of the electric field change over time, electromagnetic fields can be classified into static and time-varying fields. The treatment of bone remodeling diseases with static magnetic fields primarily focuses on fractures, often using magnetic splints to immobilize the fracture site while studying the effects of static magnetic fields on bone healing. However, there has been relatively little research on the prevention and treatment of osteoporosis using static magnetic fields. Pulsed electromagnetic fields, a type of time-varying field, have been widely used in clinical studies for treating fractures, osteoporosis, and non-union. However, current clinical applications are limited to low-frequency, and research on the relationship between frequency and biological effects remains insufficient. We believe that different types of electromagnetic fields acting on bone can induce various “secondary physical quantities”, such as magnetism, force, electricity, acoustics, and thermal energy, which can stimulate bone cells either individually or simultaneously. Bone cells possess specific electromagnetic properties, and in a static magnetic field, the presence of a magnetic field gradient can exert a certain magnetism on the bone tissue, leading to observable effects. In a time-varying magnetic field, the charged particles within the bone experience varying Lorentz forces, causing vibrations and generating acoustic effects. Additionally, as the frequency of the time-varying field increases, induced currents or potentials can be generated within the bone, leading to electrical effects. When the frequency and power exceed a certain threshold, electromagnetic energy can be converted into thermal energy, producing thermal effects. In summary, external electromagnetic fields with different characteristics can generate multiple physical quantities within biological tissues, such as magnetic, electric, mechanical, acoustic, and thermal effects. These physical quantities may also interact and couple with each other, stimulating the biological tissues in a combined or composite manner, thereby producing biological effects. This understanding is key to elucidating the electromagnetic mechanisms of how electromagnetic fields influence biological tissues. In the study of electromagnetic fields for bone remodeling diseases, attention should be paid to the biological effects of bone remodeling under different electromagnetic wave characteristics. This includes exploring innovative electromagnetic source technologies applicable to bone remodeling, identifying safe and effective electromagnetic field parameters, and combining basic research with technological invention to develop scientifically grounded, advanced key technologies for innovative electromagnetic treatment devices targeting bone remodeling diseases. In conclusion, electromagnetic fields and multiple physical factors have the potential to prevent and treat bone remodeling diseases, and have significant application prospects.
