BACKGROUND:Exercise as a form of active rehabilitation can improve the dysfunction caused by peripheral nerve injury,and different exercise modalities target different lesion sites and recovery mechanisms. OBJECTIVE:To comprehensively analyze the application and mechanisms of different exercise modalities in functional recovery from peripheral nerve injury. METHODS:A computerized search was conducted in PubMed and CNKI databases for relevant literature published before January 2024.The search terms used were"peripheral nerve injury,spinal cord,exercise,cerebral cortex,muscle atrophy,mirror therapy,blood flow restriction training"in both English and Chinese.Finally,77 articles were included for review. RESULTS AND CONCLUSION:Peripheral nerve injury can cause systemic pathological changes such as skeletal muscle atrophy,corresponding spinal cord segmental lesions,and sensorimotor cortex remodeling.Aerobic exercise can improve dysfunction by enhancing the immune response,promoting glial cell polarization,and promoting the release of nerve growth factor.Blood flow restriction exercise can regulate the secretion of muscle growth factor,promote muscle growth and enhance muscle strength.Mirror movement has a good effect in activating the cerebral cortex and reducing cortical remodeling.Different exercise modalities have potential benefits in functional recovery after peripheral nerve injury;however,there are still some problems and challenges,such as the choice of exercise modalities,the control of exercise intensity and frequency,and the detailed analysis of mechanisms.

BACKGROUND:The capability of repairing articular cartilage damage is very limited,and tissue engineering technology provides new therapeutic options for repairing damaged cartilage,in which the interaction and induction between chondrocytes,bone marrow mesenchymal stem cells,and synovial mesenchymal stem cells is the basis of autologous healing of cartilage damage. OBJECTIVE:To construct the chondrocyte-bone marrow mesenchymal stem cell-synovial mesenchymal stem cell co-culture system to simulate the in vitro microenvironment of chondrocytes,and to explore the optimal cell inoculation ratio,meanwhile to observe the effects of icariin-containing serum on the proliferation of chondrocytes and the chondrogenic differentiation of stem cells in the system. METHODS:Rat knee chondrocytes,bone marrow mesenchymal stem cells and synovial mesenchymal stem cells were extracted,cultured and identified,and a chondrocyte-bone marrow mesenchymal stem cell-synovial mesenchymal stem cell non-contact co-culture system was constructed according to different cell inoculation ratios.After 72 hours of co-culturing,the chondrocyte proliferative activity and phenotypic ability were observed,and the co-culture system with the best overall effect was selected.New Zealand white rabbits were gavaged with icariin solution(0.25 mg/mL)to prepare icariin-containing serum,and cultured in conventional complete medium(high sugar DMEM culture medium containing 10%fetal bovine serum and 1%double antibody by volume)as the control group,while the experimental group was intervened by adding 10%icariin-containing serum by volume on the basis of above.The proliferative activity of chondrocytes and the expression of collagen type II were tested for the two groups after 24 and 48 hours.The differentiation of bone marrow mesenchymal stem cells and synovial mesenchymal stem cells into chondrocytes in the co-culture system was tested by immunofluorescence staining after 14 days. RESULTS AND CONCLUSION:(1)The three kinds of cells grew normally adherently to the wall in different ratios of co-culture,where chondrocytes showed the best proliferative activity and phenotypic ability in the co-culture system when chondrocytes:bone marrow mesenchymal stem cells:synovial mesenchymal stem cells=2:1:1.(2)Compared with the control group,the proliferative activity and type II collagen expression of chondrocytes in the experimental group were significantly increased after 24 hours(P<0.01),and the two groups still had difference after 48 hours(P<0.05).The two groups showed obvious chondrogenic differentiation of bone marrow mesenchymal stem cells and synovial mesenchymal stem cells after 14 days(P<0.01),and some of the cells appeared round or oval,and the cytoplasmic type II collagen immunofluorescence staining was positive.The fluorescence intensity of the experimental group was significantly higher than that of the control group(P<0.01).(3)The results showed that the chondrocyte-bone marrow mesenchymal stem cell-synovial mesenchymal stem cell co-culture system could be successfully established by the non-contact co-culture method,and the best chondrocyte proliferative activity and phenotypic ability could be obtained when the cell ratio was 2:1:1.Icariin-containing serum had the promoting effect on chondrocyte proliferation,and chondrogenic differentiation of bone marrow mesenchymal stem cells and synovial mesenchymal stem cells in the system.

BACKGROUND:Ferroptosis is closely associated with the pathogenesis of ischemic stroke,and targeting ferroptosis is a promising regimen for the treatment of ischemic stroke,but the specific regulatory targets are unclear. OBJECTIVE:To screen ferroptosis-related characterized genes in ischemic stroke by bioinformatics and machine learning methods and validate them by cellular experiments to investigate the role of ferroptosis in ischemic stroke. METHODS:Eligible ischemic stroke-related datasets and ferroptosis expression datasets were selected based on GEO database and FerrDb database,and ferroptosis-related differential genes were screened by t-test.GO functional enrichment analysis with KEGG signaling pathway enrichment analysis was performed for ferroptosis-related differential genes.Characterized genes for ferroptosis in ischemic stroke were screened by PPI network analysis and machine learning.The reliability and biological functions of the characterized genes were explored using ROC analysis and GSEA analysis,followed by cell experiment.HT22 cells were divided into control and ischemic stroke groups.No intervention was made in the control group,and 0.1 mM H2O2 was added to the ischemic stroke group for 24 hours to simulate cellular oxidative stress injury and ferroptosis.The ferroptosis and the expression of characterized genes were verified by real-time fluorescence quantitative polymerase chain reaction(RT-PCR)and western blot assay. RESULTS AND CONCLUSION:(1)Forty-five ferroptosis-associated differential genes were obtained,and GO and KEGG enrichment analyses revealed that the differential genes were closely associated with oxidative stress,autophagy,ferroptosis,adipocytokine signaling pathway,and mitochondrial metabolism.(2)A total of one ferroptosis characterized gene,nuclear factor erythroid 2-related factor 2(NFE2L2),was identified by the MCODE plugin and cytoHubba plugin in the PPI network with the LASSO algorithm and SVM-RFE algorithm in machine learning.(3)Receiver operating characteristic curve analysis of NFE2L2 revealed that the diagnostic prediction models constructed in the training and validation sets had good accuracy and specificity.GSEA analysis of NFE2L2 revealed that the characterized gene was involved in the regulation of ischemic stroke pathogenesis through immunity,inflammatory response,amino acid metabolism,and neurofactor regulation.(4)RT-PCR and western blot analyses showed that the acyl coenzyme A synthetase long chain family,member 4(ACSL4)mRNA and protein expression levels were significantly higher in the ischemic stroke group compared with the control group(P<0.05),and the glutathione peroxidase 4(GPX4)mRNA and protein expression levels were significantly lower in the ischemic stroke group(P<0.05).Compared with the control group,the mRNA and protein expression levels of the characterized gene NFE2L2 were significantly higher in the ischemic stroke group(P<0.05).(5)It suggests that ischemic stroke is closely related to ferroptosis,and targeting the characterized gene NFE2L2 may provide certain ideas and directions for the study and treatment of ischemic stroke.

ObjectiveTo observe the clinical efficacy and safety of Bushen Ruyan Formulation (补肾乳岩方, BRF) in treating premenopausal breast cancer patients of disharmony of the chong (冲) and ren (任) meridian type under endocrine intensive therapy. MethodsA total of 88 premenopausal breast cancer patients who received endocrine intensive therapy and were diagnosed with disharmony of the chong and ren meridian by traditional Chinese medicine (TCM) were included and randomly divided into a control group and a treatment group, with 44 cases in each group. The control group received ovarian function suppression (OFS) combined with endocrine therapy, while the treatment group was given oral BRF additionally. Both groups were treated for three months. The clinical efficacy was evaluated by comparing the pre- and post-treatment results of the Functional Assessment of Cancer Therapy-Breast (FACT-B), modified Kupperman score, T cell subsets (CD3+, CD4+, CD8+, CD4+/CD8+), sex hormone levels, including estradiol (E2), luteinizing hormone (LH), follicle-stimulating hormone (FSH), progesterone (P), testosterone (T), and prolactin (PRL), tumor markers, such as carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), and carbohydrate antigen 153 (CA153), TCM syndrome score, and TCM syndrome efficacy. Blood routine tests, liver function and kidney function were monitored to assess safety. ResultsThe FACT-B scores of each domains and the total scores of the treatment group increased, while the social/family status score of the control group decreased. The treatment group had significantly higher scores in all domains and total score compared to the control group (P<0.05 or P<0.01). The modified Kupperman score and TCM syndrome score of the treatment group decreased, and were lower than those of the control group (P<0.01). The levels of CD3+ and CD4+ in the treatment group increased, and were higher than those of the control group (P<0.05). Serum testosterone levels in the treatment group were lower than those in the control group (P<0.05). The total effective rate of TCM syndrome efficacy in the treatment group was 67.44%, significantly higher than the 23.26% in the control group (P<0.05). No significant abnormalities were observed in the blood routine tests or liver/kidney function indicators in either group before or after treatment. ConclusionBRF can effectively improve quality of life, alleviate symptoms, increase serum CD3+ and CD4+ levels, and enhance clinical efficacy in premenopausal breast cancer patients undergoing endocrine intensive endocrine therapy. It is also safe with no significant adverse effects.

Vascular cognitive impairment (VCI), caused by cerebrovascular dysfunction, severely impacts the quality of life in the elderly population, yet effective therapeutic approaches remain limited. Mitophagy, a selective mitochondrial quality-control mechanism, has emerged as a critical focus in neurological disease research. Accumulating evidence indicates that mitophagy modulates oxidative stress, neuroinflammation, and neuronal apoptosis. Key signaling pathways associated with mitophagy—including PINK1/Parkin, BNIP3/Nix, FUNDC1, PI3K/Akt/mTOR, and AMPK—have been identified as potential therapeutic targets for VCI. This review summarizes the mechanistic roles of mitophagy in VCI pathogenesis and explores emerging therapeutic strategies targeting these pathways, aiming to provide novel insights for clinical intervention and advance the development of effective treatments for VCI.

ObjectiveTo preliminarily explore the active components and target pathways of Angelicae Sinensis Radix-Polygonati Rhizoma (ASR-PR) herb pair in the treatment of simple obesity through network pharmacology and molecular docking, and to verify and investigate its mechanism of action via animal experiments. MethodsThe chemical constituents and targets of ASR and PR were predicted using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Targets related to simple obesity were identified by retrieving the GeneCards, Online Mendelian Inheritance in Man (OMIM), Pharmacogenomics Knowledgebase (PharmGKB), and DisGeNET databases. The intersection of drug and disease targets was used to construct an active component-target network using Cytoscape software. This network was imported into the STRING database to construct a protein-protein interaction (PPI) network, and topological analysis was conducted to identify core genes. Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and mapping were performed using the DAVID database and the Microbioinformatics platform. AutoDock 1.5.7 software was used to perform molecular docking between the top five active components and core targets. An animal model of simple obesity was established by feeding C57BL/6J mice a high-fat diet. The mice were administered ASR (2.06 g·kg-1), PR (2.06 g·kg-1), or ASR-PR (4.11 g·kg-1) for 10 weeks, while the model group received an equal volume of purified water by gavage. After the administration period, the mice were sacrificed to measure body fat weight and serum levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL). Hematoxylin-eosin (HE) staining was used to observe histopathological sections of liver and adipose tissue. Serum levels of leptin, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were determined by enzyme-linked immunosorbent assay (ELISA), and the mRNA expression levels of epidermal growth factor receptor (EGFR) and signal transducer and activator of transcription 3 (STAT3) in liver tissue were detected by real-time quantitative polymerase chain reaction (Real-time PCR). ResultsNetwork pharmacology and molecular docking results indicated that the treatment of simple obesity by ASR-PR may involve the regulation of protein expression of core targets EGFR and STAT3 by its main components MOL009760 (Siberian glycoside A_qt), MOL003889 (methyl protodioscin_qt), MOL009766 (resveratrol), MOL006331 (4′,5-dihydroxyflavone), and MOL004941 (baicalin), thereby modulating the PI3K/Akt and JAK/STAT signaling pathways. The animal experiment results showed that compared with the normal group, the model group had significantly increased body weight, body fat weight, and serum levels of TG, TC, TNF-α, IL-6, and leptin (P<0.01). EGFR mRNA expression was significantly elevated (P<0.05), while STAT3 mRNA expression was significantly decreased (P<0.01). Histological analysis revealed disordered hepatic architecture in the model group, with pronounced lipid vacuoles, cytoplasmic loosening, lipid accumulation, and steatosis. Adipocytes in white adipose tissue (WAT) and brown adipose tissue (BAT) of the model group exhibited markedly increased diameters, reduced cell counts per unit area, and irregular morphology. Compared with the model group, the ASR-PR group significantly reduced body weight, body fat weight, serum TC, IL-6, TNF-α, leptin levels, and EGFR mRNA expression (P<0.01). TG levels were also significantly decreased (P<0.05), while STAT3 mRNA expression was significantly increased (P<0.01). Histopathological improvements included reduced size and number of hepatic lipid vacuoles and restoration of liver cell morphology toward that of the normal group. The diameter of adipocytes significantly decreased, and the number of adipocytes per unit area increased. ConclusionASR-PR may regulate the expression of key target proteins such as EGFR and STAT3 via its core active components, modulate the PI3K/Akt and JAK/STAT signaling pathways, repair damaged liver and adipose tissues, and thereby alleviate the progression of obesity in mice.

ObjectiveTo assess the therapeutic effectiveness and safety of the traditional Chinese medicine compound Shenlong decoction in addressing the symptoms of pulmonary deficiency and stasis in patients with idiopathic pulmonary fibrosis (IPF). MethodsSixty eligible patients with lung deficiency and collateral stasis syndrome of IPF were randomly assigned to the observation (30 patients) and control groups (30 patients). All patients underwent standard Western medical therapy. Additionally,the observation group received Shenlong decoction granules,while the control group received a placebo. Both treatments were packaged in four doses of 10.5 g each,taken twice daily for three months. The indexes of the patients during the treatment cycle were observed,and the main indexes include traditional Chinese medicine (TCM) syndrome scores and 6 min walk test (6MWT). The secondary indexes include pulmonary function test [actual value/expected value of total lung volume (TLC%),actual value/expected value of vital capacity(FVC%),actual/predicted diffusing capacity of the lung for carbon monoxide(DLCO%),actual/predicted forced expiratory volume in one second (FEV1%),and FEV1/ forced vital capacity (FVC)],blood gas analysis [arterial blood diathesis partial pressure of oxygen (PaO2),partial pressure of carbon dioxide (PaCO2),and arterial oxygen saturation (SaO2)],serum inflammatory factors [transforming growth factor-β1 (TGF-β1),interleukin-4 (IL-4),interleukin-13 (IL-13),interleukin-12 (IL-12),and gamma-interferon (IFN-γ)],and quality of survival evaluation [St George's Respiratory Questionnaire (SGRQ) score]. The patients' clinical manifestations were determined at the end of the treatment, and the occurrence of adverse events was recorded. ResultsA total of 53 patients completed the study,comprising 27 in the control group and 26 in the observation group. Upon completion of the treatment period,the control group achieved a total effective rate of 33.33% (9/27),whereas the observation group demonstrated a total effective rate of 53.85% (14/26),which was statistically superior to the control group (χ2=4.034,P<0.05). After the treatment,the TCM syndrome scores,6MWT,DLCO%,FEV1%,PaO2,PaCO2,TGF-β1,IL-4,IL-13,IL-12,and IFN-γ in the two groups were all significantly improved (P<0.01). Compared with those in the control group after treatment at the same period,the TCM syndrome scores,6MWT,PaO2,and PaCO2 were significantly improved in the observation group after 60 days and 90 days of medication (P<0.01). Three months after the end of medication,the SGRQ score in the observation group showed significant improvement when compared to that in the control group (P<0.05),and no severe adverse events were reported during the follow-up period. ConclusionCompound Shenlong decoction can alleviate clinical symptoms such as shortness of breath and wheezing in patients with lung deficiency and collateral stasis syndrome of IPF,enhance exercise tolerance,improve the quality of life,and have certain potential advantages in improving pulmonary function.
