ObjectiveTo reveal the mechanism of Zuogui Jiangtang Jieyu prescription against damage to hippocampal synaptic microenvironment via suppressing glutamate receptor 2 (GluR2)/Parkin signal-mediated mitophagy in rats with diabetes-related depression (DD). MethodsEighty male SD rats underwent adaptive feeding for 5 days before the study. Ten rats were randomly assigned to the normal group. The model of DD rats was established with the rest by 2-week high-fat diet + streptozotocin (STZ) tail intravenous injection + 28 days of chronic unpredictable mild stress (CUMS) combined with isolation. The rats were randomly divided into a normal group, a model group, a GluR2 blocker group (5 μg·kg-1), a GluR2 agonist group (10 μg·kg-1), a metformin + fluoxetine group (0.18 g·kg-1 metformin + 1.8 mg·kg-1 fluoxetine), and high- and low-dose Zuogui Jiangtang Jieyu prescription groups (20.52 and 10.26 g·kg-1, respectively). The rats in the GluR2 blocker group and the GluR2 agonist group were continuously injected with CNQX and Cl-HIBO in the dentate gyrus of the hippocampus once a week starting from stress modeling, respectively, while the metformin + fluoxetine group and the high- and low-dose Zuogui Jiangtang Jieyu prescription groups were continuously given intragastric administration for 28 d at the same time of stress modeling. Depression-like behavior was evaluated by open field and forced swimming experiments. The levels of serum insulin and adenosine triphosphate (ATP) in hippocampus were detected by biochemical analysis. The levels of 5-hydroxytryptamine (5-HT) and dopamine (DA) in hippocampus were detected by enzyme-linked immunosorbent assay (ELISA). The autophagosomes of hippocampal neurons were observed by transmission electron microscopy. The morphology and structure of dendrites and spines of hippocampal neurons were evaluated by Golgi staining. Western blot detected the expression levels of GluR2 and Parkin proteins in hippocampus. The expression levels of GluR2, Parkin, regulating synaptic membrane exocytosis protein 3 (RIMS3), and postsynaptic density protein 95 (PSD95) in the dentate gyrus of the hippocampus were detected by immunofluorescence. ResultsCompared with the normal group, the model group exhibited reduced total activity distance in the open field and increased immobility time in forced swimming (P<0.01), lowered levels of serum insulin and ATP, 5-HT, and DA in hippocampus (P<0.01), increased autophagosomes of hippocampal neurons, significantly damaged morphology and structure of dendrites and spines of hippocampal neurons, decreased expression levels of GluR2, RIMS3, and PSD95 in hippocampus, and an increased Parkin expression level (P<0.05, P<0.01). Compared with the model group, the GluR2 blocker group and the GluR2 agonist group showed aggravation and alleviation of the above abnormal changes, respectively (P<0.05, P<0.01). The above depression-like behavior was significantly improved in the high- and low-dose Zuogui Jiangtang Jieyu prescription groups to different degrees. Specifically, the two groups saw elevated levels of serum insulin and ATP, 5-HT, and DA in hippocampus (P<0.05, P<0.01), restrained increase in autophagosomes and damage to morphology and structure of dendrites and spines of hippocampal neurons, up-regulated protein expression levels of GluR2, RIMS3, and PSD95, and down-regulated Parkin expression level (P<0.05, P<0.01). ConclusionZuogui Jiangtong Jieyu prescription can ameliorate the mitophagy-mediated damage to hippocampal synaptic microenvironment in DD rats, the mechanism of which might be related to the regulation of GluR2/Parkin signaling pathway.

ObjectiveTo explore the mechanism by which the ethanol extract of Epimedium brevicornu (EEBM) intervenes in mesenchymal adipose-derived stem cells (ADSCs) to delay aging in castrated rats. MethodsForty-five 3-month-old SPF female SD rats were ovariectomized and randomly divided into model group, ADSCs treatment group, and ADSCs groups treated with low, medium, and high concentrations of EEBM (1, 50, 100 μg·L-1), referred to as the AE low, medium, and high concentration groups, with 9 rats in each group. After tail vein injection of 200 μL of the corresponding stem cell suspension, aging-related indicators including cyclin-dependent kinase inhibitor (p21), tumor suppressor gene (p53), interleukin-6 (IL-6), interleukin-8 (IL-8), superoxide dismutase (SOD), malondialdehyde (MDA), B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), cysteine-aspartic acid protease-3 (Caspase-3), and lipofuscin were measured using enzyme-linked immunosorbent assay (ELISA) and Western blot. ResultsCompared with the model group, the IL-6 content in the AE low, medium, and high concentration groups was significantly decreased (P<0.05). Lipofuscin, MDA, and IL-8 levels in the ADSCs treatment group and AE low, medium, and high concentration groups were significantly reduced (P<0.01), while SOD content was significantly increased (P<0.05, P<0.01). Compared with the ADSCs treatment group, lipofuscin and IL-8 levels in the AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01). The MDA content was significantly decreased in the AE medium concentration group (P<0.01). Compared with the model group, protein levels of p21, p53, Bax, and Caspase-3 in the ADSCs treatment group and AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01), while the Bcl-2 protein level was significantly increased (P<0.01). Compared with the ADSCs treatment group, protein levels of p21, p53, Bax, and Caspase-3 in the AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01), and the Bcl-2 protein level in the AE low concentration group was significantly increased (P<0.01). ConclusionThe results of this experiment show that EEBM-treated ADSCs or ADSCs may delay aging in castrated rats by inhibiting cell apoptosis, reducing cell cycle inhibitors and pro-inflammatory factors, enhancing antioxidant capacity, and reducing oxidative reactions. Moreover, EEBM-treated ADSCs demonstrate stronger anti-aging effects than ADSCs alone. This study provides experimental evidence supporting the clinical use of EEBM to intervene in ADSCs and delay aging.

Atopic dermatitis (AD) is a common pruritic and chronic inflammatory dermatosis in clinical practice and is one of the diseases responding specifically to traditional Chinese medicine (TCM). With the launch of biological agents and small molecule drugs and the development and implementation of guidelines of diagnosis and treatment, clinical pathways of treatment of moderate to severe AD, and consensus on the whole-process management of AD, the clinical efficacy of moderate to severe AD has been significantly improved. However, there are still many unmet clinical needs that require more effective methods to meet. In response to the Opinions of the CPC Central Committee and the State Council on Facilitating the Inheritance, Innovation, and Development of Traditional Chinese Medicine and the spirit of the National Conference on TCM, the China Association of Chinese Medicine organized more than 20 experts in TCM dermatology, Western medicine dermatology, interdisciplinary fields, and industries to discuss the difficulties and advantages of TCM in the treatment of AD. TCM treatment for AD can not only improve rash and relieve itching but also solve many concomitant syndromes. The abundant external treatment methods of TCM have advantages for different special populations and rash characteristics. The concept of treating disease before its onset in TCM is in line with the chronic disease management mode of prevention and treatment of atopic march and prevention of recurrence. In addition, TCM therapy can reduce the use of topical glucocorticoids and has good safety. Regarding the comorbidity of AD, equal emphasis on TCM and Western medicine and multidisciplinary joint treatment should be advocated to achieve maximum benefit for patients. The exchange of TCM and Western medicine has clarified the positioning and advantages of TCM intervention in AD, providing guidance for clinical and scientific research.

Uveitis is a blinding inflammatory disease that affects multiple structures within the eye, posing significant risks to patients' vision and mental health. Current treatments mainly involve glucocorticoids and immunosuppressants, which are associated with significant side effects, high relapse rates, and substantial costs. Recent research suggests that the gut microbiota may play a role in the development of uveitis through the gut-eye axis, with related metabolites also influencing disease progression. Modulating the gut microbiota or its metabolites could offer new therapeutic avenues for uveitis. This review explores the relationship between gut microbiota and various uveitis-associated diseases, such as systemic sarcoidosis, Vogt-Koyanagi-Harada syndrome, Behcet's disease, multiple sclerosis, and birdshot chorioretinopathy. It also discusses advancements in microbiota-related therapies, including probiotics and prebiotics, antibiotics, immunomodulators, phage therapy, and fecal microbiota transplantation. The aim is to provide a reference for the development of new therapies targeting specific microbial communities and genetic markers associated with uveitis, thereby promoting the realization of precision medicine.

AIM: To analyze the clinical outcomes of cyclosporine combined with lacrimal plug in the treatment of dry eye in patients with primary Sjögren's syndrome.METHODS: The clinical data of 60 patients(120 eyes)who were admitted to the ophthalmology department and rheumatology and immunology department of Baoding No.1 Central Hospital and were diagonosed with siogren's syndrome dry eye after multidisciplinary consultation from June 2022 to September 2023 were retrospectively analyzed. All the patients received regular treatment of primary Sjögren's syndrome, and they were divided into three groups according to treatment methods: A, B and C, with 20 cases(40 eyes)in each group. The group A received 0.3% sodium hyaluronate eyedrops, the group B received 0.3% sodium hyaluronate eyedrops plus 0.05% cyclosporine eyedrops, and the group C received 0.3% sodium hyaluronate eyedrops plus 0.05% cyclosporine eyedrops combined with binocular lacrimal plugs. The ocular surface disease index(OSDI)score, conjunctival hyperemia score, tear film breakup time(BUT), tear meniscus height(TMH), corneal fluorescein staining(FL)score and tear secretion of the three groups of patients were compared before and at 4, 8 and 12 wk after treatment. The contents of inflammatory factors such as interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)in tears were detected before and at 12 wk after treatment.RESULTS: At 4, 8 and 12 wk after treatment, the scores of OSDI, conjunctival hyperemia score and FL in the three groups of patients were lower than those before treatment, and the BUT, TMH and tear secretion were higher than those before treatment(all P<0.001). The OSDI score of the group C was lower than that of the group A and B, and the group B was lower than the group A(all P<0.001). The BUT, TMH and tear secretion of the group C were higher than those of the group A and B, with the group B higher than the group A(all P<0.001). At 12 wk after treatment, the levels of IL-6, TNF-α and IL-1β in the tears of the three groups of patients were lower than those before treatment, with the group C lower than the group A and B, and the group B lower than the group A(all P<0.001). There was no statistical significant difference in the incidence of adverse reactions among the three groups of patients(P>0.05).CONCLUSION: The combined use of cyclosporine and lacrimal plug is safe and effective in improving the clinical symptoms of patients with moderate and severe dry eye, promoting the function of tear film and cornea, increasing tears secretion, and reducing the level of tear inflammatory factors.

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.

Medicinal plants, with diverse species, high heterozygosity, and special breeding objectives, can be hardly bred with conventional hybridization techniques. Plant genetic transformation is highly selective and can specifically change the traits of plants, serving as an important technical means for the breeding of medicinal plants. The commonly used plant genetic transformation technologies include Agrobacterium-mediated transformation and particle bombardment. Agrobacterium-mediated transformation is the most widely used method, while it is not applicable to all medicinal plants due to the high specificity. Although not specific, particle bombardment is limited in application due to the low conversion efficiency and external force damage to cells and tissue. With the rise and development of nanotechnology, the emerging nanomaterial-mediated transformation has solved the problems of the above two technologies. However, limited by its late development, the mechanism of nanomaterial-mediated introduction of genetic materials into plant cells remains unclear, and thus this technology is rarely used in medicinal plants. This article summarizes the development status of several commonly used or emerging plant genetic transformation technologies such as Agrobacterium-mediated transformation, particle bombardment, and nanomaterial-mediated transformation, as well as their application in different medicinal plants. Furthermore, this article looks forward to the development trend of genetic transformation technologies for plants and their application prospects in medicinal plants and Chinese materia medica resources, aiming to provide new technical ideas for the genetic improvement and germplasm innovation of medicinal plants and inject new impetus into the sustainable development of Chinese materia medica resources.
