ObjectiveTo investigate the effects of mitotically-associated long non-coding RNA （lncRNA MANCR） on the proliferation，migration， and epithelial mesenchymal transition （EMT） of gastric cancer （GC） cells by regulating the microRNA-50-5p （miR-150-5p）/non-metastatic melanoprotein B （GPNMB） axis. MethodsThe mRNA expressions of lncRNA MANCR，miR-150-5p， and GPNMB in 42 cases of GC tissue and adjacent tissue resected during surgery in the First Hospital of Hebei Medical University from June 2022 to September 2023 were detected by Real-time PCR. Human gastric mucosal epithelial cells GES-1 and human GC cells BGC-823 were cultured in vitro， and their lncRNA MANCR expression was detected. BGC-823 cells were randomly separated into control group （routine culture），sh-NC group （with sh-NC transfected），sh-MANCR group （with sh-MANCR transfected），sh-MANCR + anti-NC group （with sh-MANCR and anti-NC both transfected），and sh-MANCR + anti-miR-150-5p group （with sh-MANCR and anti-miR-150-5p both transfected）. The mRNA expressions of lncRNA MANCR，miR-150-5p， and GPNMB in the BGC-823 cells of all groups were analyzed. EdU staining was used to detect the proliferation of BGC-823 cells. Transwell assay was used to detect the migration and invasion of BGC-823 cells. The expressions of EMT-related proteins E-cadherin，N-cadherin，Vimentin， and GPNMB were detected by Western blot. The interactions between lncRNA MANCR and miR-150-5p and between miR-150-5p and GPNMB were analyzed by dual luciferase reporter assay. ResultsThe mRNA expressions of lncRNA MANCR and GPNMB in GC tissue were higher than those in adjacent tissue，and the expression of miR-150-5p was lower than that in adjacent tissue （P<0.05）. Compared with that in GES-1，lncRNA MANCR expression in BGC-823 cells was increased （P<0.05）. Compared with those in the sh-NC group and control group，the EdU-positive cell rate，migration number，invasion number，the mRNA expressions of lncRNA MANCR and GPNMB， and the expressions of protein，N-cadherin protein， and Vimentin protein in the BGC-823 cells in the sh-MANCR group were lower ，and the protein expressions of miR-150-5p and E-cadherin were higher （P<0.05）. Compared with those in the sh-MANCR group and the sh-MANCR + anti-NC group，the protein expressions of miR-150-5p and E-cadherin in the sh-MANCR + anti-miR-150-5p group were decreased. The EdU-positive cell rate，migration number，invasion number，mRNA expressions of GPNMB， and expressions of protein，N-cadherin protein， and Vimentin protein were increased （P<0.05）. lncRNA MANCR could target the negative regulation of miR-150-5p，and miR-150-5p could target the negative regulation of GPNMB. ConclusionKnockout of lncRNA MANCR can inhibit the proliferation，migration， and EMT of GC cells by regulating the miR-150-5p/GPNMB axis.

Objective: To investigate the effects of Zuogui Jiangtang Jieyu Formula (ZGJTJYF) on histone H3 lysine 18 lactylation (H3K18la) in the hippocampus of rats with diabetes mellitus complicated with depression (DD) and predict the regulatory genes of H3K18la. Methods: Male Sprague-Dawley rats were divided into control, model, and positive drug (metformin [0.18 g/kg] and fluoxetine [1.8 mg/kg]) groups, and the three groups were treated with high, medium, and low ZGJTJYF doses (20.52, 10.26, and 5.13 g/kg, respectively), with 10 rats per group. After treatment, the forced swimming and water maze tests were performed to assess depressive-like behaviors and cognitive function. An enzyme-linked immunosorbent assay was used to measure blood insulin, glycosylated hemoglobin, lactate levels, and lactate content in the hippocampus. Western blotting was used to detect H3K18la expression in the hippocampus. Cleavage Under Targets and lagmentation(CUT&Tag) experiments targeted hippocampal H3K18la epigenetic modification regions to analyze the transcription factors bound by H3K18la. Kyoto Encyclopedia of Genes and Genomes and Protein-Protein Interaction networks were constructed to identify key pathways and target genes regulated by H3K18la. Results: Compared with the normal group, the model group rats showed prolonged immobility time in the forced swim test, increased escape latency in the water maze experiment, decreased target quadrant distance ratio (P<0.01), increased serum lactate content, and decreased lactate content in hippocampal homogenate (P<0.01), as well as decreased H3K18la protein expression in the hippocampus (P<0.01). Compared with the model group, ZGJTJYF reduced the immobility time in the forced swim test and the escape latency in the water maze test (P<0.01), while the distance ratio in the target quadrant increased (P<0.01) in model rats. Lowered fasting blood glucose, insulin, and glycosylated hemoglobin levels (P<0.05, P<0.01) were also observed. ZGJTJYF also increased the lactate content and H3K18la protein expression in hippocampal homogenate (P<0.05, P<0.01). The DNA sequences bound by H3K18la were predominantly enriched at the transcription start sites. ZGJTJYF modulated H3K18la-associated pathways, including cell adhesion junctions, tumor growth factor-beta (TGF-β) signaling, stem cell pluripotency regulation, mitogen-activated protein kinase(MAPK) signaling pathway, and insulin resistance, leading to the identification of 12 target genes. Conclusion ZGJTJYF enhances hippocampal lactate levels and H3K18la modification in DD rats, which may regulate neural cell interactions, neurogenic stem cell function, TGF-β signaling, MAPK signaling, and insulin resistance pathways.

Aging is an inevitable, physiological process of the human body, leading to deterioration in bodily function and increased susceptibility to various diseases. Effective endogenous therapeutic strategies for anti-aging and related diseases remain limited. Exercise confers multifaceted benefits to physical health by augmenting osteogenic and myogenic processes, enhancing cardiovascular and nervous system function, and attenuating chronic inflammation. Angiogenesis and lymphangiogenesis play pivotal roles in anti-aging, tissue repair, and immune response modulation, underscoring their potential as therapeutic targets for age-related diseases. Modulating angiogenic and lymphangiogenic pathways may provide a promising strategy for mitigating vascular decline and immune system dysfunction associated with aging. Exercise-induced endogenous angiogenesis and lymphangiogenesis can exert beneficial effects on physiological function, thereby representing a potential therapeutic paradigm for combating age-related decline and diseases. This review offers a thorough summary of the present knowledge regarding angiogenesis and lymphangiogenesis induced by exercise, encompassing the underlying mechanisms and the effects in different organs. In addition, it explores the potential of physical activity as a non-pharmacological intervention for anti-aging strategies and disease management, offering novel insights into the intersection of physical activity, aging, and disease progression.

Lung cancer is the leading cause of cancer-related deaths worldwide,with metastasis being the primary cause of mortality in lung cancer patients,and its prevention and control efficacy remain limited.In recent years,immunothera-py has emerged as a promising direction for overcoming the bottleneck of metastasis.Macrophages,as essential components of innate immunity,participate in the entire process of tumor initiation and progression.Tumor-associated macrophages(TAMs)represent the most abundant immune population in the tumor microenvironment(TME),displaying both anti-tumor M1-like and pro-tumor M2-like phenotypes.The latter promotes tumor invasion and metastasis,angiogenesis,lymphangiogenesis,immune suppression,and reactivation of dormant disseminated tumor cells(DTCs),thereby facilitating tumor metastasis.In recent years,traditional Chinese medicine(TCM)has shown significant efficacy in inhibiting tumor metastasis and has been extensively validated.It exerts anti-tumor effects by reducing the recruitment of TAMs,inhibiting M2-like polarization,and modulating cytokines and proteins in the TME.This paper reviews the relationship between TAMs and lung cancer metastasis,elucidates the targets and mechanisms of TCM in regulating TAMs to prevent and treat lung cancer metastasis,aiming to pro-vide insights into lung cancer prevention and treatment.

Objective:To explore the application effect of rotating skin flap in the repair of skin and soft tissue defects in the perineum.Methods:A retrospective analysis was conducted on the data of 9 patients with perineal soft tissue defects treated in the Department of the First Affiliated Hospital, Wenzhou Medical University from January 2022 to March 2024. Among them, 8 cases were soft tissue defects after extensive resection of Paget′s disease in the perineum, and 1 case was soft tissue defects after treatment of severe urethral stricture. The defect area ranged from 4 cm×1.5 cm to 30 cm×35 cm, and all wounds were repaired with rotating skin flaps, For patients with excessive area, rotating skin flaps were used to cover important areas, combined with autologous skin and artificial skin to cover the remaining wounds. Patients with urethral stricture were treated with free oral mucosal reconstruction of the urethra combined with rotational skin flap coverage. The donor site was directly sutured or autologous skin was transplanted.Results:After surgery, the recipient skin flaps of 9 patients survived and the donor area healed. After a follow-up of 9-15 months, the skin flap survived well, with skin color approaching normal, and the donor site wound healed well. Eight patients with Paget′s disease did not show any recurrence, among which one patient with extensive wound expansion had good recovery of the perineal skin flap coverage area, and small-scale chronic ulcers appeared in the skin graft area. The skin flap of the patient with urethral stricture had recovered well, and the shape of the penis was good, without any urethral stricture, urinary fistula, sinus tract, etc.Conclusions:The rotational skin flap has a clear therapeutic effect on perineal soft tissue defects and is suitable for repairing perineal skin and soft tissue defects.

ObjectiveTo explore and verify the key pathway of Zuogui Jiangtang Jieyu prescription in the treatment of diabetes with depression by means of gene set enrichment analysis （GSEA） and short time-series expression miner （STEM）. MethodSD rats were randomly divided into six groups， including a normal group， a model group， high， medium， and low dose groups of Zuogui Jiangtang Jieyu prescription， and a positive drug group. The model of diabetes with depression was established by high-fat feeding， streptozotocin （STZ） injection， and chronic mild unpredictable stress. The high， medium， and low dose groups of Zuogui Jiangtang Jieyu prescription were orally administered at 20.52， 10.26， and 5.13 g·kg^-1 respectively. The positive drug group was orally administered 0.18 g·kg^-1 metformin and 1.8 g·kg^-1 fluoxetine. The rats in the normal group and model group were administered with an equal volume of distilled water. After 28 days， the animals were tested for depressive-like behaviors and cognitive function using the forced swimming test and Morris water maze. Fasting blood glucose was measured using blood glucose test strips. Cholesterol and triglyceride levels were measured using enzyme-linked immunosorbent assay （ELISA）. Three hippocampus samples were randomly selected from the normal group， the model group， the high dose group of Zuogui Jiangtang Jieyu prescription for high-throughput transcriptome sequencing. Differential gene analysis， GSEA analysis， and STEM analysis were used to screen the key pathways and target genes of Zuogui Jiangtang Jieyu prescription in the treatment of diabetes with depression. Key target genes were validated using real-time fluorescence quantitative PCR （Real-time PCR）. The expression of the signal protein mediated by the target genes was detected by Western blot. ResultCompared with the results in the normal group， the fasting blood glucose， cholesterol， and triglyceride levels in the model group were significantly increased （P<0.01）. Moreover， the immobility time in the forced swimming test was significantly increased， while the time to climb the platform was significantly prolonged， and the search distance in the target quadrant was significantly reduced in the Morris water maze test （P<0.05，P<0.01）. Compared with the model group， the high dose of Zuogui Jiangtang Jieyu prescription significantly reduced the levels of blood glucose， cholesterol， and triglycerides in rats with diabetes with depression （P<0.05，P<0.01）， reduced the immobility time in the forced swimming test， shortened the stage time in the Morris water maze test， and increased the search distance ratio in the target area （P<0.05，P<0.01）. Transcriptome sequencing differential analysis showed that the normal group had 1 366 differentially expressed genes compared to the model group， while the model group had 1 149 differentially expressed genes compared to the high dose group of Zuogui Jiangtang Jieyu prescription， with 581 intersecting genes. The GSEA results showed that there were 9 sets of differentially expressed genes between the normal group and the model group， and 43 sets of differentially expressed genes between the model group and the high dose group of Zuogui Jiangtang Jieyu prescription， with 7 intersecting gene sets. STEM analysis showed that according to the analysis order of the normal group， model group， and high dose group of Zuogui Jiangtang Jieyu prescription， two significantly different trend clustering groups were obtained. One key gene set for axonal guidance， as well as key target signal elements Sema3c， Sema7a， Robo3， Epha8， and Epha7， were identified through synthesizing the three analysis results. Real-time PCR validated that compared with the results in the normal group， the mRNA expression of Robo3， Sema7a， and Epha7 in the hippocampus of the model rats was significantly reduced （P<0.05， P<0.01）. Compared with the model group， the high dose of Zuogui Jiangtang Jieyu prescription significantly increased the mRNA expression of Robo3， Sema7a， and Epha7 （P<0.05， P<0.01）. Western blot results showed that compared with the results in the normal group， the Sema7a， ITGB1， and FAK protein expression in the hippocampus of the model group was significantly reduced （P<0.01）. Compared with the model group， the high dose of Zuogui Jiangtang Jieyu prescription significantly increased the protein expression of Sema7a， ITGB1， and FAK in the hippocampus （P<0.05，P<0.01）. ConclusionZuogui Jiangtang Jieyu prescription may treat diabetes with depression by regulating axonal guidance based on the Sema7a/ITGB1 signaling pathway.
