ObjectiveNonalcoholic fatty liver disease (NAFLD) is a metabolic stress liver injury. Ferroptosis is involved in the occurrence and development of NAFLD. Exploring the efficacy and mechanism of schisandrin B in treating NAFLD facilitates the development of strategies for the prevention and treatment of NAFLD. MethodsThe molecular structure of schisandrin B was obtained by searching against PubChem, and the related targets were predicted by SwissTargetPrediction. The active ingredients and their targets were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and the high-throughput experiment- and reference-guide database of traditional Chinese medicine (HERB). GeneCards and FerrDb were searched for the targets of NAFLD and ferroptosis. The common targets were taken as the core targets, and the protein-protein interaction network of the core targets was established. DAVID was used for gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. Finally, molecular docking was performed between schisandrin B and core targets, and the binding energy was calculated. C57BL/6 mice were fed with a methionine and choline-deficiency (MCD) diet for the modeling of NAFLD. Mice were randomized into normal, model, positive drug (essentiale), and low- and high-dose schisandrin B groups. The body mass and liver index of mice were measured after drug administration. The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the serum and those of total cholesterol (TC), triglyceride (TG), malondialdehyde (MDA), glutathione (GSH), and Fe2+ in the liver homogenate were measured by biochemical assay kits. The pathological changes of the liver tissue were observed by hematoxylin-eosin (HE) and red oil O staining. Enzyme-linked immunosorbent assay was employed to determine the levels of interleukin (IL)-6, IL-1β, tumor necrosis factor (TNF)-α, and 4-hydroxynonenal (4-HNE) in the serum. Western blotting and real-time PCR were employed to determine the protein and mRNA levels, respectively, of solute carrier family 7 member 11 (SLC7A11), solute carrier family 3 member 2 (SLC3A2), glutathione peroxidase 4 (GPX4), transferrin, and ferritin heavy chain (FTH) in the liver tissue. ResultsA total of 2 370, 2 547, and 1 451 targets of schisandrin B, NAFLD, and ferroptosis were obtained, in which 90 common targets were shared by the three. Enrichment analyses predicted 505 GO terms and 92 KEGG pathways. Molecular docking suggested that schizandrin B had strong binding affinity with the key targets of ferropstosis (SLC7A11 and SLC3A2). Animal experiments showed that schizandrin B significantly decreased the liver index, lowered the levels of ALT, AST, TC, TG, IL-6, IL-1β, and TNF-α, alleviated hepatocyte ballooning and inflammatory cell infiltration, and reduced lipid accumulation in the liver of NAFLD mice. In addition, schisandrin B significantly lowered the levels of MDA, 4-HNE, and Fe2+, elevated the level of GSH, up-regulated the protein and mRNA levels of SLC7A11, SLC3A2, and GPX4, and down-regulated the protein and mRNA levels of transferrin in the liver tissue. ConclusionSchisandrin B can alleviate NAFLD by inhibiting ferroptosis in hepatocytes.

ObjectiveTo investigate the effects of Dihuang Yinzi on the cognitive function in the mouse model of learning and memory impairments induced by scopolamine (SCOP) and explore the treatment mechanism. MethodsA mouse model of learning and memory impairment was induced by intraperitoneal injection of SCOP. Sixty male C57BL/6J mice were randomized into six groups: control (0.9% NaCl, n=10), model (SCOP 1 mg·kg-1·d-1, n=10), low-, medium-, and high-dose Dihuang Yinzi (SCOP 1 mg·kg-1·d-1 + Dihuang Yinzi 5.5, 11.0, and 22.0 g·kg-1·d-1, n=10), and donepezil (SCOP 1 mg·kg-1·d-1 + donepezil 0.84 mg·kg-1·d-1, n=10). Mice were administrated with corresponding drugs for 6 weeks. Modeling started in the 4th week, and mice in other groups except the control group were injected with SCOP intraperitoneally 40 min after daily gavage. Behavioral testing began in the 5th week, 30 min after modeling each day. The Morris water maze and novel object recognition tests were carried out to evaluate the spatial learning and memory function of mice. Nissl staining was employed to observe the survival of neurons and Nissl bodies in the hippocampal CA1 region. Western blot was employed to determine the protein levels of silent information regulator 2 (SIRT2), α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor 1 (GluA1), protein kinase A (PKA), cAMP response element-binding protein (CREB), phosphorylated-CREB (p-CREB), postsynaptic density protein 95 (PSD95), growth-associated protein-43 (GAP-43), and synaptophysin (SYN) in the hippocampus. Immunofluorescence was used to detect the expression of doublecortin (DCX) in the hippocampal dentate gyrus (DG) region. ResultsCompared with the control group, the model group showed impaired learning and memory (P<0.01), obvious neuronal damage in the hippocampal CA1 region, a reduction in neuron survival (P<0.01), a decrease in DCX expression in the hippocampal DG region (P<0.01), down-regulated proteins levels of GluA1, PKA, p-CREB/CREB, PSD95, SYN, and GAP-43 in the hippocampal tissue (P<0.05, P<0.01), and an up-regulated protein level of SIRT2 (P<0.01). Compared with the model group, the medium- and high-dose Dihuang Yinzi groups and the donepezil group showed improvements in learning and memory (P<0.05, P<0.01), while the low-, medium-, and high-dose Dihuang Yinzi groups and the donepezil group had increased neuron survival (P<0.05, P<0.01). The medium-dose Dihuang Yinzi group and the donepezil group showed increased DCX expression (P<0.05, P<0.01). The medium- and high-dose Dihuang Yinzi groups and the donepezil group showed up-regulation in the protein levels of GluA1, PKA, p-CREB/CREB, PSD95, SYN, and GAP-43 (P<0.05, P<0.01) and down-regulation in the protein level of SIRT2 (P<0.01). ConclusionDihuang Yinzi can improve the cognitive function in the mouse model of learning and memory impairments induced by SCOP by inhibiting the upregulation of SIRT2, activating the PKA/CREB signaling pathway, improving synaptic plasticity, and reducing hippocampal neuronal damage.

Avian coccidiosis, an acute parasitic disease that mainly harms chicks, is widely prevalent across the world, which poses a serious threat to poultry industry. Because of the single prophylactic formulations, veterinary clinical treatment of coccidiosis mainly relies on chemically synthesized agents, polyether ionophores and Chinese herbal medicines. The introduction of novel anticoccidial drugs is slow for a long period of time, and there is an increasing problem of anticoccidial drug resistance following long-term use, which has become an urgent problem to be solved in poultry industry. This review summarizes the levels of anticoccidial drug resistance across China from 2018 to 2023, and analyzes the resistance to various anticoccidial agents in coccidia. It is indicated that the overall prevalence of anticoccidial drug resistance is high in coccidia, and development of novel anticoccidial agents and products with reduced antibiotics use and alternatives of antibiotics is of an urgent need.

Mild cognitive impairment due to Alzheimer′s disease is an inevitable pathological stage in the early development of Alzheimer′s disease, which can be classified as "microlumps in the brain collaterals" in traditional Chinese medicine. Based on the theory of latent toxin blocking collaterals, this article discusses the etiology and pathogenesis, clinical sequelae, and traditional Chinese medicine intervention strategies for mild cognitive impairment due to Alzheimer′s disease. The onset of mild cognitive impairment due to Alzheimer′s disease is very similar to the latent pathogen theory, which states that "the latent pathogen is latent and then develops, the poison is deep and difficult to cure, and the development can be recognized but the latent pathogen cannot be detected." Combining clinical experience, our team believes that the basic nature of the disease is a slight deficiency and a slight excess of symptoms. A slight deficiency of the five zang viscera and six fu viscera as root and a latent toxin colling collaterals of qi, fire, phlegm, and blood stasis as manifestaion. These usually start from the qi depression and develop into phlegm coagulation and blood stasis, then end up in latent toxin and gradually become the healthy qi deficiency. Therefore, the deficiency of vital qi and incubation of evil, latent toxin blocking collaterals the pathogenesis of early intervention of this disease should be carried out, upholding the idea that "the upper workman treats the disease before it is diagnosed." The principle of strengthening vital qi to eliminate pathogenic factors, slowing down and promoting pathogenic factors elimination, establishing the method of supporting correctness and wisdom, simultaneously detoxifying and clearing the blood stasis, pattern differentiation as the main and the disease differentiation as the first, combining the disease and pattern, and adjusting the macroscopic and microscopic, focusing simultaneously on eliminating and replenishing, dispel phlegm and remove blood stasis, achieve a strong vital qi and the elimination of evil, and enhance intelligence, delay or even block the progression of mild cognitive impairment due to Alzheimer′s disease, improve patients′ quality of life, and provide a theoretical basis for the early clinical prevention and treatment of Alzheimer′s disease.

OBJECTIVE To investigate the effect mechanism of Gualou guizhi granule on neurological function and synaptic plasticity in rats with cerebral ischemia-reperfusion injury. METHODS The rats were randomly divided into sham operation group, model group and Gualou guizhi granule group (3.6 g/kg), with 6 rats in each group. The cerebral ischemia-reperfusion injury model was established by the suture occlusion method. Two hours after modeling, the model rats were given relevant medicine or normal saline intragastrically, once a day, for 7 consecutive days. After the last medication, the neurological function of rats was evaluated [calculated by modified neurological severity scores (mNSS) and corner turning percentage]; the neuronal apoptosis rate of brain histiocyte in the ischemic side of rats was detected in each group; the positive expressions of growth associated protein 43 (GAP43) and microtubule associated protein 2 (MAP2) were detected; protein expressions of neuron-specific nuclear protein (NeuN), synaptophysin-1 (Syn-1), postsynaptic density protein-95 (PSD-95), peroxisome proliferators-activated receptor γ (PPARγ), brain-derived neurotrophic factor (BDNF) and tropomyosin receptor kinase B (TrkB), as well as mRNA expressions of NeuN, Syn-1 and PSD-95 were detected. RESULTS Compared with the model group, mNSS, corner turning percentage and neuronal apoptotic rate were decreased significantly in Gualou guizhi granule group (P<0.01); GAP43 represented weak immunoreactivity, and MAP2 represented moderate immunoreactivity; protein expressions of NeuN, Syn-1, PSD-95, PPARγ, BDNF, TrkB and mRNA expressions of Syn-1, NeuN, PSD-95 were all increased significantly (P<0.05 or P<0.01). CONCLUSIONS Gualou guizhi granule can promote synaptic plasticity by activating BDNF/TrkB signaling pathway, thus playing a protective role in cerebral ischemia-reperfusion injury in rats.

Cardiometabolic disease is a clinical syndrome with a causal relationship between metabolic abnormalities and cardiovascular damage. With its global incidence and related mortality rates continually rising, it has become a major health concern worldwide. The role of the gut microbiome and its metabolic products in cardiovascular metabolic health has received widespread attention, with gut microbiota dysbiosis considered a key factor in promoting the development of cardiometabolic disease. Dysbiosis disrupts the balance of the "heart-spleen-intestine" axis, leading to dysfunction of the spleen and intestines, which triggers metabolic disorders and accelerates the progression of cardiometabolic disease. Cardiac dysfunction can also negatively affect spleen and intestinal function, leading to imbalances in the heart and spleen, disharmony in Qi and blood, and exacerbating metabolic anomalies and further dysbiosis, thus forming a vicious cycle. From a modern biological perspective, the gut microbiome and its metabolic products can influence disease progression by modulating inflammatory responses and immune imbalances, leading to endothelial dysfunction and metabolic disorders, thereby increasing the risk of cardiometabolic disease. Additionally, the article proposes strategies for managing cardiometabolic disease by regulating the gut microbiome through a combination of Chinese and western medicine approaches. Traditional Chinese medicine(TCM) treatment starts from the gut microbiome, using the "heart-spleen-intestine" axis as a mediator to regulate cardiovascular metabolic health, highlighting the unique advantages of TCM in targeting the gut microbiome to treat cardiometabolic disease. This article takes the TCM theory of the "heart-spleen-intestine" axis as a starting point, discusses the pivotal role played by this axis in the connection between gut microbiome dysbiosis and the development of cardiometabolic disease, aiming to provide a new perspective for the integrated traditional Chinese and western medical research on cardiometabolic disease, offering scientific evidence and practical guidance to improve the prognosis and quality of life for patients.

The treatment of glioblastoma, the most prevalent malignant tumor in the central nervous system, poses considerable challenges. Glioblastoma multiforme, classified as a grade Ⅳ highly malignant brain glioma by the World Health Organization, is typically managed through a combination of surgery, postoperative chemotherapy, and radiotherapy. The treatment of glioblastoma is complicated by its infiltrative nature, genetic heterogeneity, and presence of the blood-brain barrier. Almost all cases of glioblastoma experience recurrence despite aggressive therapy, exploring the development of updated molecular treatment strategies that can improve overall efficacy. A crucial aspect in modern neurosurgery is the precise delineation of brain regions in terms of their anatomy and function. It serves as the fundamental basis for investigating variations in the distribution of brain gliomas. Hence, this review will elucidate the origin of glioblastomas and analyze the potential factors contributing to the spatially specific distribution of gliomas on the basis of a theoretical framework of brain connectomics research. Molecular characteristics, information pathways, tumor microenvironment landscape, and immunology will inform the analysis. We aim to identify novel biomolecular targets and therapeutic pathways to gain scientific insights for effective glioblastoma treatment.

Objective To compare the application of four domestic and foreign qualitative occupational health risk assessment methods for cement dust hazard assessment and explore their applicability, and to find out a method suitable for qualitative occupational health risk assessment of cement dust. Methods The Risk Assessment Method for Occupational Accidents and Diseases of Romania (Romania method),the Australian Occupational Health and Safety Risk Assessment Method (Australia method),MES method, and the qualitative method of International Council on Mining & Metals (ICMM) were used to assess the occupational health risk of cement dust exposure posts in seven enterprises of Chongqing. The assessment results were analyzed and compared with Spearman correlation analysis, Mann-Whitney U test and weighted Kappa consistency test after standardizing by risk ratio (RR). Results The RRs of the four methods were all positively correlated with cement dust exposure concentration (the correlation coefficients were all greater than 0.6). The Romania method, the Australia method and the qualitative method of ICMM could identify a risk difference between the key posts and non-key posts. The qualitative method of ICMM was difficult to identify high-risk posts that require priority intervention. The Romania method and Australia method had strong consistency (Kappa=0.608, P<0.01), but only the Australia method could identify high-risk posts of cement dust. Conclusion In general, the Australia method is relatively better at identifying the risk differences of cement dust hazard in different posts and is more suitable for occupational health risk assessment of cement dust with more accurate assessment results.
