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.

Diabetic cardiomyopathy (DCM) is one of the most common complications of diabetes mellitus and is a major threat to global health. As a key mechanism in the occurrence and progression of DCM, the inflammatory response persists throughout the entire course of the DCM. The Gaozhuo theory suggests that the basic pathogenesis of inflammatory injury in DCM is the Qi deficiency of spleen and kidney and Gaozhuo invasion, and divides the pathological process into three phases: Gaozhuo invasion, turbid heat damage to the channels, and turbid blood stasis and heat junction. Among them, the Qi deficiency of spleen and kidney and the endogenous formation of Gaozhuo represent the process of inflammatory factor formation induced by glucose metabolism disorders. Turbid heat damage to the channels refers to the process of myocardial inflammatory injury mediated by inflammatory factors, and turbid blood stasis and heat junction are the process of myocardial injury developing toward myocardial fibrosis and ventricular remodeling. As the disease continues to progress, it eventually develops into a depletion of the heart Yang, leading to the ultimate regression of heart failure. According to the theory of Gaozhuo, traditional Chinese medicine (TCM) should regulate inflammatory injury in DCM by strengthening the spleen and tonifying the kidney to address the root cause, and resolving dampness and lowering turbidity to treat the symptoms. If the turbidity has been stored for a long time and turns into heat, strengthening the spleen and tonifying the kidney, and clearing heat and resolving turbidity should be the therapy. If the turbidity, stasis, and heat are knotted in the heart and collaterals, strengthening the spleen and tonifying the kidney, and resolving stasis and lowering turbidity should be the therapy. TCM compounds and monomers can regulate the inflammatory response in DCM. TCM compounds can be divided into the categories for benefiting Qi to resolve turbidity, benefiting Qi and clearing heat to resolve turbidity, and benefiting Qi and activating blood to reduce turbidity. The compounds can inhibit upstream signals of inflammation and expression of inflammatory factors, improve the inflammatory damage to myocardium and blood vessels, myocardial fibrosis, and cardiac systole and diastole, and thus slow down the onset and progression of DCM.

ObjectiveTo explore the mechanism by which Tangbikang granules improve diabetic peripheral neuropathy based on ferroptosis mediated by the adenosine monophosphate-activated protein kinase/nuclear factor erythroid 2-related factor 2 (AMPK/Nrf2) signaling pathway. MethodsA diabetes model was established using spontaneous male Zucker diabetic fatty (ZDF) rats. After successful modeling, the rats were divided into a normal group, a model group, high-, medium-, and low-dose Tangbikang granules groups, and a metformin hydrochloride group. The high-, medium-, and low-dose Tangbikang granules groups were administered by gavage at doses of 2.5, 1.25, 0.625 g·kg-1, respectively. The metformin hydrochloride group received 0.135 g·kg-1 by gavage, while the remaining groups received an equal volume of deionized water. Administration continued for 12 weeks. Blood glucose levels were measured after administration, and at 4, 8, 12 weeks. Following the 12-week intervention, the thermal pain threshold and the sciatic nerve conduction velocity (SNCV) were measured. The levels of malondialdehyde (MDA), superoxide dismutase (SOD), and adenosine triphosphate (ATP) in the sciatic nerve were measured using enzyme-linked immunosorbent assay (ELISA). Morphological changes in the sciatic nerve were observed using hematoxylin and eosin (HE) staining, and the ultrastructural changes were examined using transmission electron microscopy. The levels of glutathione peroxidase 4 (GPx4) were detected using immunofluorescence (IF) assay. The protein expression levels of p-AMPK, Nrf2, GPx4, and acyl-CoA synthetase long-chain family member 4 (ACSL4) were detected using Western blot. ResultsCompared with the normal group, the model group had significantly higher blood glucose levels after administration and at weeks 4, 8 and 12 (P<0.01). The thermal pain threshold was significantly prolonged (P<0.01), and the SNCV was significantly slowed down (P<0.01). The SOD and ATP levels significantly decreased (P<0.01), while the MDA levels significantly increased (P<0.01). Pathologically, the sciatic nerve fibers in the model group showed a dispersed structure, disordered and sparse arrangement, axonal atrophy, irregular myelin sheath halo, increased and swollen Schwann cell nuclei, obvious endoneurial fibrosis, and collagen hyperplasia. Immunofluorescence assay revealed fragmented red fluorescence and significantly reduced expression of GPx4 (P<0.01). Western blot analysis showed significantly decreased protein expression levels of p-AMPK, Nrf2, and GPx4 (P<0.01), and significantly increased expression of ACSL4 (P<0.01) in the model group. Compared with the model group, fasting blood glucose level decreased significantly in the high-dose Tangbikang granules group at weeks 4 and 12 (P<0.05). The thermal pain threshold was significantly shortened in the high- and medium-dose Tangbikang granules groups (P<0.01). The SNCV was significantly accelerated in the high- and medium-dose Tangbikang granules groups (P<0.01). The SOD levels were significantly elevated in the high-dose Tangbikang granules group (P<0.01). The MDA levels significantly decreased in all Tangbikang granules groups (P<0.01). Both the metformin hydrochloride group and the high-dose Tangbikang granules group exhibited relatively orderly and densely arranged sciatic nerve fibers with more regular myelin sheath halos. The GPx4 expression significantly increased in both the metformin hydrochloride group and all Tangbikang granules groups (P<0.01). The protein expression levels of p-AMPK, Nrf2, and GPx4 were significantly increased (P<0.01), while ACSL4 protein expression significantly decreased (P<0.01). ConclusionTangbikang granules may improve peripheral neuropathy by suppressing ferroptosis through the regulation of the AMPK/Nrf2 signaling pathway.

ObjectiveTo investigate the effect of different visual inputs and task conditions on balance function and lower limb biomechanical characteristics in children with spastic hemiplegia. MethodsFrom March to July, 2025, 30 children aged six to nine years old with spastic hemiplegia (hemiplegia group) and 30 healthy children (control group) were selected. A 2×2×2 mixed experimental design was employed, involving groups (hemiplegia vs. healthy), tasks (single-task vs. dual-task), and vision (eyes open vs. eyes closed). One week before test, they were evaluated with Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Wee Function Independent Measurement (WeeFIM) and Wechsler Intelligence Scale for Children, Fourth Edition (WISC-Ⅳ). A 3D gait analysis system and a plantar pressure testing system were used to collect spatio-temporal parameters of walking speed, stride length, cadence and step width, kinematic parameters of hip/knee/ankle joint angles, kinetic parameters of forefoot loading ratio, center of pressure (CoP) displacement, while dual-task cost (DTC) was caculated. ResultsSpatio-temporal parameters showed that under dual-task and eyes-closed conditions, walking speed and stride length decreased while step width increased in the hemiplegia group. Significant interaction effects among group, task, and vision were observed for speed, stride length, and step width (F > 4.886, P < 0.05). Kinematic parameters indicated that during dual-tasks, the hemiplegia group exhibited increased hip flexion and decreased ankle dorsiflexion; under eyes-closed conditions, knee flexion increased. The interaction of the three factors significantly affected all joint angles (F > 4.876, P < 0.05). Kinetic parameters showed that under dual-task and eyes-closed conditions, the forefoot loading ratio and anteroposterior CoP displacement decreased, while mediolateral CoP displacement increased. The interaction of the three factors significantly affected CoP displacement (F > 4.355, P < 0.05). All the DTC was significantly higher in the hemiplegia group than in the control group, except DTC of the cadence (|t| > 14.393, P < 0.001). Correlation analysis revealed that the score of FMA-LE was strongly negatively correlated with DTC (|r| > 0.731, P < 0.01). The Functional Independence Measure for Children and Working Memory Index showed moderate negative correlations with the DTC of walking speed and cadence (|r| > 0.462, P < 0.05). ConclusionThe gait and balance of children with spastic hemiplegia are concurrently influenced by dual-tasking and visual input. The superposition of visual deprivation and dual-tasks significantly exacerbates gait abnormalities. Furthermore, is strongly correlated with motor function and working memory.

Congenital blood group chimerism refers to the coexistence of two or more distinct blood types within an individual, resulting from the presence of hematopoietic cell populations with different genotypes. Consequently, red blood cells in such individuals may express different blood group antigens. Based on the timing and mechanism of formation, blood group chimerism can be classified as either congenital or acquired. Although congenital blood group chimerism is rare and involves complex mechanisms, it holds significant implications in transfusion medicine, transplantation, and obstetrics. This article reviews the formation mechanisms, detection methods, and clinical significance of congenital blood group chimerism in transfusion medicine. Particular emphasis is placed on the principles, advantages, and limitations of various detection techniques. Furthermore, the potential applications of these technologies in clinical diagnosis are discussed, providing a technical foundation for the development of precise transfusion strategies.

OBJECTIVE To evaluate the clinical comprehensive value of four Chinese patent medicines (Xuezhikang, Zhibitai, Zhibituo, Jiangzhiling) in the treatment of hyperlipidemia, and provide a reference for rational clinical drug use. METHODS A clinical comprehensive evaluation index system was established in accordance with the Evidence and Value: Impact on Decision-Making (EVIDEM) framework and Technical Guideline for Clinical Comprehensive Evaluation of Cardiovascular Drugs (2022 edition, trial implementation). CNKI, Wanfang data, VIP, PubMed, ScienceDirect, Embase and official websites were retrieved to collect the literature such as drug instructions, guidelines and consensus statements, and systematic reviews/meta-analyses for the four Chinese patent medicines. A comprehensive evaluation was conducted from seven dimensions: effectiveness, safety, economy, suitability, accessibility, innovation and characteristics of traditional Chinese medicine. RESULTS This evaluation index system included 7 first-level indicators, 15 second-level indicators and 30 third-level indicators. Xuezhikang achieved the highest comprehensive evaluation score of 81.4 points, and was classified as class Ⅰ recommendation. Zhibitai with 76.0 points and Zhibituo with 60.9 points were both classified as class Ⅱ recommendation. Jiangzhiling with 48.8 points was classified as class Ⅳ recommendation. CONCLUSIONS Xuezhikang demonstrates the optimal clinical comprehensive value for treating hyperlipidemia. Zhibitai exhibits certain advantages in terms of safety and characteristics of traditional Chinese medicine; Zhibituo shows a moderate performance in all aspects; Jiangzhiling has a relatively low score. Appropriate medicines can be selected clinically according to actual conditions and patients’ characteristics.

Chronic eczema has a high prevalence in China, significantly impacting patients’ quality of life. Leveraging the unique advantages of pattern identification/syndrome differentiation and treatment, along with a holistic approach, traditional Chinese medicine (TCM), which integrates internal and external therapies, has been widely applied in the management of chronic eczema. It has demonstrated significant efficacy and distinctive strengths in alleviating symptoms, reducing recurrence rates, maintaining disease stability, and enhancing patients’ quality of life. Oral administration of TCM(e.g. modified Longdan xiegan decoction) can improve patients’ clinical symptoms through systemic regulation. External use of TCM can directly act on the skin lesion with the help of steaming and washing, hydropathic compress, ointment and other forms. At the same time, it can effectively relieve the clinical symptoms of chronic eczema by combining with non-drug therapies such as acupuncture, moxibustion, acupoint catgut embedding, blood-letting puncture and cupping. In addition, characteristic therapies such as oral administration of TCM combined with external treatment, a combination of various external treatments and a combination of Chinese and Western medicine have also demonstrated certain advantages in regulating immune function, alleviating skin lesions, and relieving itching symptoms. These therapies cooperate with each other, creating a synergistic effect that treats both the symptoms and the root cause simultaneously. It is suggested that more high-quality, large-scale clinical research should be conducted in the future to systematically confirm the therapeutic advantages of TCM and further explore the specific molecular mechanism of action.
