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.

Idiopathic intracranial hypertension (IIH) is a neurological disorder characterized by an unexplained increase in intracranial pressure that primarily affects obese women of childbearing age, but individuals of any age, gender, or weight may also be affected. Its signature symptoms include disc edema, headache, visual disturbance, and throbbing tinnitus. Due to potentially serious complications, such as vision loss, accurate diagnosis and appropriate treatment management are critical to improving patients' quality of life. Ophthalmologists play a key role in the treatment process, as about half of patients first visit the eye department. Diagnosis of IIH depends not only on clinical presentation, but also on the exclusion of other diseases that may cause similar symptoms, and imaging and other tests to ensure an accurate diagnosis. In order to improve diagnostic accuracy and treatment efficiency, multidisciplinary collaborative diagnosis and treatment mode is advocated, especially in the face of patients with complex trauma or systemic diseases, which can effectively shorten the treatment time and ensure patient safety. Future research directions include establishing China's IIH epidemiological database, exploring clinical diagnosis and treatment methods and basic scientific research, aiming at forming diagnosis and treatment standards suitable for China's national conditions, improving medical level and improving patient prognosis. At the same time, a deeper understanding of the different forms of IIH will better serve the affected populations.

Objective To identify clinicopathological parameters that differentiate between very high-risk and ordinary high-risk gas-trointestinal stromal tumors(GISTs)to provide guidance for clinical treatment and follow-up monitoring.Methods A retrospective cohort study was conducted,collecting 174 cases of high-risk GISTs initially diagnosed and surgically resected at Tianjin Medical University Cancer Institute and Hospital between January 1st,2011,and December 31st,2019.Based on long-term follow-up data,the X-tile software was used to identify key parameters for screening very high-risk GISTs from ordinary high-risk GISTs,and the results were validated by using high-risk GIST cases from the cBioPortal database.Results Among the 174 high-risk GIST cases,the X-tile software indicat-ed that the maximum tumor diameter of 14 cm,the mitotic count of 14/5 mm2,and the Ki-67 proliferation index of 10%were the optimal cutoff values for distinguishing very high-risk GISTs from ordinary high-risk GISTs.Univariate survival analysis confirmed that these cutoff values were associated with progression free survival(PFS,all P<0.05).Multivariate survival analysis confirmed that the maximum tumor diameter≥14 cm(HR=5.727,P<0.01),mitotic count≥14/5 mm2(HR=2.454,P=0.047),and Ki-67 proliferation index≥10%(HR=2.275,P=0.047)were independent risk factors for tumor progression in high-risk GIST patients.High-risk GISTs with any one of the three parameters more than or equal to its optimal cutoff value were defined as very high-risk GISTs,and the other GISTs were defined as ordinary high-risk GISTs.Compared to very high-risk GIST patients,the ordinary high-risk GIST patients had superior PFS(P<0.01),and a trend toward better overall survival(OS,P=0.082).Stratified analysis showed that,in subgroups of patients with gastric or non-gas-tric primary tumors,those receiving or not receiving adjuvant therapy,and those with KIT proto-oncogene,receptor tyrosine kinase(KIT)gene mutations,ordinary high-risk GIST patients all exhibited superior PFS compared to very high-risk GIST patients(all P<0.05).Both PFS and OS of ordinary high-risk GIST patients in the cBioPortal database were better than those of very high-risk GIST patients(both P=0.001).Stratified analysis of the cBioPortal database data showed that,in subgroups of patients with gastric or non-gastric primary tu-mors,those who received adjuvant therapy,and those with KIT gene mutations,ordinary high-risk GIST patients all exhibited superior PFS compared to very high-risk GIST patients(all P<0.05);conversely,among patients who did not receive adjuvant therapy,very high-risk GIST patients showed a trend toward poorer PFS(P=0.366).Conclusions This study has established a method utilizing commonly used clinical parameters to distinguish very high-risk GISTs in clinical practice.However,further validation through multicenter studies with larger sample sizes is still required.

Objective:To investigate the preventive and therapeutic effects and mechanisms of Dachaihu decoction(DCD)on dextran sodium sulfate(DSS)-induced ulcerative colitis(UC)and liver injury in mice,as well as the association between DCD benefits and gut microbiota modulation.Methods:Mice were treated with DCD(20.10 and 10.05 g/kg)for 2 weeks,with free access to drinking water containing 3%DSS in the second week to induce UC.Histopathological examination,RT-qPCR and 16S rRNA sequencing were used to investigate the effect of DCD on UC mice.Results:DCD pretreatment significantly alleviated weight loss,bloody diarrhea with mucus,histopathological abnormalities of the colon,and colon shortening in mice with DSS-induced UC.In addition,DCD pretreat-ment significantly upregulated the levels of Occludin,ZO-1,and MUC-2 in the colon and protected the intestinal barrier of mice.DCD pretreatment also alleviated inflammatory cell infiltration in the colon and the liver and significantly reduced the expression levels of the proinflammatory factors such as IL-1β,IL-6,TNF-α,iNOS,COX-2,and NLRP3,thereby exerting a protective effect against UC and liver injury.It should be noted that DCD corrected gut micro-biota imbalance in UC mice by enriching probiotic bacteria such as Lactobacillus and Bifidobacterium and reducing harmful bacteria such as Norank_f_Desulfovibrionaceae and Escherichia-Shigella.Conclusion:DCD can alleviate DSS-induced UC and exert a liver-protecting effect by protecting intestinal barrier,inhibiting inflam-mation,and regulating gut microbiota.
