ObjectiveTo observe the clinical efficacy of Sanren Runchang formula in treating constipation-predominant irritable bowel syndrome (IBS-C) by regulating the brain-gut axis and the effects of the formula on serum levels of 5-hydroxytryptamine (5-HT), vasoactive intestinal peptide (VIP), and substance P (SP). MethodsA randomized controlled design was adopted, and 72 IBS-C patients meeting Rome Ⅳ criteria were randomized into observation and control groups (36 cases).The observation group received Sanren Runchang formula granules twice daily, and the control group received lactulose oral solution daily for 4 weeks. IBS Symptom Severity Scale (IBS-SSS), IBS Quality of Life Scale (IBS-QOL), and Bristol Stool Form Scale (BSFS) were used to assess clinical symptoms, and bowel movement frequency was recorded. The Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were employed to evaluate psychological status. ELISA was employed to measure the serum levels of 5-HT, VIP, and SP. ResultsThe total response rate in the observation group was 91.67% (33/36), which was higher than that (77.78%, 28/36) in the control group (χ2=4.50, P<0.05). After treatment, both groups showed increased defecation frequency and BSFS scores, decreased IBS-SSS total score, abdominal pain and bloating scores, IBS-QOL health anxiety, anxiety, food avoidance, and behavioral disorders scores, SAS and SDS scores, serum 5-HT and VIP levels, and increased SP levels (P<0.05, P<0.01). Moreover, the observation group showed more significant changes in the indicators above than the control group (P<0.05, P<0.01). The SP level showed no significant difference between the two groups. During the 4-week follow-up, the recurrence rate was 5.88% in the observation group and 31.25% in the control group. No adverse events occurred in observation group, and 2 cases of mild diarrhea occurred in the control group. ConclusionSanren Runchang formula demonstrated definitive efficacy in alleviating gastrointestinal symptoms and improving the psychological status and quality of life in IBS-C patients, with a low recurrence rate. The formula can regulate serum levels of neurotransmitters such as 5-HT and VIP, suggesting its potential regulatory effect on the brain-gut axis through modulating neurotransmitters and neuropeptides. However, its complete mechanism of action requires further investigation through detection of additional brain-gut axis-related biomarkers.

ObjectiveTo explore the interaction and competitive binding of Homo sapiens long intergenic non-protein-coding RNA 1134 (LINC01134) to CCCTC-binding factor CTCF, affecting the transcription of cyclin-dependent kinase inhibitor (p21) and influencing the proliferation of A549 cells, in order to investigate the possible mechanism of Astragali Radix and Hedyotis diffusa (A-H) in inhibiting A549 proliferation by regulating this axis. MethodsRNA-binding protein immunoprecipitation (RIP) assays were conducted to examine the interaction between LINC01134 and CTCF, and chromatin immunoprecipitation (ChIP) assays were used to study the effect of LINC01134 overexpression on the interaction between CTCF and p21. Stable A549 cell lines (oe-NC and oe-LINC01134) were established using lentiviral transfection, and each group was treated with 10% A-H drug-containing serum. Real-time PCR and Western blot analyses were performed to detect the effects of A-H on the expression of LINC01134, CTCF, and p21 in A549 cells. Cell counting kit-8 (CCK-8) and colony formation assays were used to assess the effects of A-H on A549 cell proliferation via LINC01134. Flow cytometry was employed to evaluate the effects of A-H on the A549 cell cycle through LINC01134, and Western blot was used to detect changes in cell cycle proteins. ResultsCompared with the IgG group, the oe-CTCF group showed a significantly increased abundance of LINC01134 aggregates (P0.01). Compared with the oe-Vector group, p21 abundance in CTCF complexes was significantly reduced in the oe-LINC01134 group (P0.01). Compared with the 10% blank + oe-LINC01134 group, the 10% A-H + oe-LINC01134 group reversed the expression of LINC01134 and p21 (P0.05), but had no significant regulatory effect on CTCF. Compared with the 10% blank + oe-LINC01134 group, the 10% A-H + oe-LINC01134 group reversed cell viability at 72 h (P0.05), inhibited malignant proliferation (P0.05), and reversed the proportions of cells in the G0/G1 and S phases (P0.01). Furthermore, compared with the 10% blank + oe-LINC01134 group, the 10% A-H + oe-LINC01134 group reversed the expression of Cyclin D1, CDK4, Cyclin E, CDK2, phosphorylated retinoblastoma protein (p-Rb), and E2F transcription factor 3 (E2F3) (P0.01). ConclusionA-H regulates the LINC01134-CTCF-p21 axis to block the G1/S phase transition of A549 cell cycle, accelerate cellular senescence, and inhibit malignant proliferation.

ObjectiveTo observe the pharmacodynamic efficacy of phlorizin in improving hepatic glycolipid metabolism disorders in type 2 diabetic mellitus (T2DM) rats and to explore its mechanism of action based on the insulin receptor substrate-1 (IRS-1)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. MethodsA high-fat diet and streptozotocin (STZ) were used to establish T2DM rat models. The rats were randomly assigned into six groups: the blank control group, model group, metformin group (300 mg·kg-1), and phlorizin high-dose (100 mg·kg-1) and low-dose groups (25 mg·kg-1). The rats were given intragastric administration for 6 weeks. The changes in body weight and fasting blood glucose (FBG) were observed, and the oral glucose tolerance test (OGTT) was carried out. The levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), glycated serum protein (GSP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) in serum were detected by an automatic biochemical analyzer. The levels of fasting insulin (FINS), interleukin (IL)-1β, IL-6, and tumour necrosis factor (TNF)-α were detected by enzyme-linked immunosorbent assay (ELISA). The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) were detected by the biochemical assays. The pancreas index, liver index, and insulin resistance index were calculated. Hematoxylin-eosin (HE) staining was used to evaluate the pathological changes in liver and pancreatic tissues. The immunofluorescence method was used to detect the changes in insulin and glucagon in pancreatic tissue. Western blot was used to detect the expression of related proteins in the IRS-1/PI3K/Akt pathway of liver tissue and its downstream glycogen synthase kinase-3β (GSK-3β) and forkhead box transcription factor O1 (FoxO1) proteins. ResultsCompared with the blank control group, the body weight of rats in the model group continued to decrease, while the FBG level increased significantly. The area under the OGTT blood glucose curve (AUC), GSP, TC, TG, LDL-C, IL-1β, IL-6, TNF-α, MDA, pancreatic index and liver index increased significantly, while the levels of HDL-C, SOD, and FINS decreased significantly (P0.05, P0.01). Histological results showed that the pancreatic islets of rats in the model group exhibited atrophy and severe structural abnormalities. The insulin-positive β-cells decreased significantly (P0.01), while the glucagon-positive α-cells increased significantly (P0.01). Inflammatory cell infiltration and partial necrosis were observed in the liver tissues of the model group rats. The expressions of p-IRS-1/IRS-1, p-GSK-3β/GSK-3β, and p-FoxO1/FoxO1 proteins in the liver of the model group increased significantly (P0.01), while the expressions of p-PI3K/PI3K and p-Akt/Akt proteins decreased significantly (P0.01). Compared with the model group, the diabetic symptoms of rats in all administration groups were improved. The changes in body weight and FBG were close to those of the blank control group. The levels of OGTT-AUC, GSP, TC, TG, LDL-C, MDA, IL-1β, IL-6, TNF-α and the pancreatic index, liver index were obviously reduced (P0.05, P0.01), while the levels of HDL-C, SOD, and FINS obviously increased (P0.05, P0.01). The pathological changes of the pancreas and liver in rats in all treatment groups were effectively improved. The insulin-positive β-cells in the pancreas increased significantly (P0.01), while the glucagon-positive α-cells decreased significantly (P0.01). The protein expressions of p-IRS-1/IRS-1, p-GSK-3β/GSK-3β, and p-FoxO1/FoxO1 in the liver were significantly reduced (P0.01), while the protein expressions of p-PI3K/PI3K and p-Akt/Akt significantly increased (P0.01). ConclusionPhlorizin reversed the weight loss and abnormal increase of FBG in T2DM rats, improved blood lipid profiles, oxidative stress, and inflammatory levels, alleviated insulin resistance, and had certain protective effects on the liver and pancreas. The hypoglycemic mechanism may involve regulating the IRS-1/PI3K/Akt signaling pathway to inhibit the activities of GSK-3β and FoxO1, thereby promoting liver glycogen synthesis and suppressing hepatic gluconeogenesis, ultimately improving glycolipid metabolism disorders.

As one of the most common malignant tumors, digestive system tumors exhibit an increase in the incidence and mortality year by year. Its pathogenesis is complex, making it difficult to carry out early prevention. Autophagy is a process in which cells use lysosomes to degrade their organelles and macromolecules to maintain cellular homeostasis under the regulation of autophagy-related genes. Cellular autophagy has a dual regulatory effect on the tumor microenvironment, which always affects the occurrence and development of digestive system tumors. Therefore, the effect and mechanism of action of cellular autophagy on digestive system tumors have become a hot topic in tumor therapy in recent years. Meanwhile, the remarkable research results of targeted autophagy drugs indicate that cellular autophagy may become an important target for anti-digestive system tumors. Traditional Chinese medicine (TCM) has been widely used in the comprehensive treatment of digestive system tumors with good efficacy. A variety of active ingredients in TCM, such as flavonoids, glycosides, terpenoids, quinones, and alkaloids, can increase the expression of autophagy-associated proteins microtubule-associated protein 1 light chain 3 (LC3)Ⅱ/Ⅰ, autophagy-related gene (ATG)5, ATG7, inhibit the expression of autophagy-related protein p62 , and induce autophagy in digestive system tumor cells, thereby exerting the anti-digestive system tumor effect. By summarizing the research results in recent years on the modulation of cell autophagy by active ingredients in TCM to fight against digestive system tumors, this paper analyzed the relevant signaling pathways, regulatory factors, and functional characteristics of cell autophagy modulation, so as to elucidate the mechanism by which active ingredients of TCM induce autophagy and to provide ideas and references for clinical application.

BACKGROUND:Epidemiological studies indicate that individuals with neurodegenerative diseases exhibit a comparatively lower risk of developing the majority of cancers.Although the precise mechanisms underlying this inverse correlation remain unclear,it is noteworthy that aberrant glucose metabolism,a pathological factor common to both conditions,may significantly contribute to this association.OBJECTIVE:To review the potential relationship between cancers and neurodegenerative diseases in glucose metabolism.METHODS:PubMed was searched for relevant literature using the search terms of"cancer,neurodegenerative diseases,Alzheimer's disease,Parkinson's disease,metabolic reprogramming,glucose metabolism,aerobic glycolysis,neuroprotection,aging,"and 136 articles were finally included for analysis.RESULTS AND CONCLUSION:Cancer and neurodegenerative diseases exhibit a profound pathological correlation at the level of glucose metabolism imbalance associated with aging.Cancer cells promote uncontrolled proliferation,invasion,and metastasis through the persistent activation of aerobic glycolysis,whereas neurodegenerative diseases are characterized by a reduction in aerobic glycolysis.Restoring aerobic glycolysis may confer neuroprotective effects and delay disease progression.The key nodes of glucose metabolism demonstrate a bidirectional regulatory pattern:metabolic regulators,which are significantly upregulated or aberrantly activated in cancer,are inhibited or functionally inactivated in neurodegenerative diseases.Mitochondria play a crucial role in mediating the aging process through the regulation of reactive oxygen species homeostasis and mitochondrial autophagy.They establish regulatory networks that connect cancer and neurodegenerative diseases,and maintaining their functional homeostasis is of paramount importance for disease prevention and treatment.

BACKGROUND:In China,the patient population with osteonecrosis is large,and there is an urgent need to find new preventive targets to develop more effective treatment strategies.Metabolomics studies have shown that there is an association between human metabolites and osteonecrosis,but the causal relationship between blood metabolites and osteonecrosis has not yet been clarified.OBJECTIVE:To investigate the causal relationship between blood metabolites and osteonecrosis through two-sample Mendelian randomization analysis.METHODS:The public data of 486 blood metabolites(exposure factors)and osteonecrosis(outcome factors)were collected.Data of 486 blood metabolites were derived from a genome-wide association estimate for blood metabolites published in Nature Genetics in 2014,which covered 7 824 European adults.The single nucleotide polymorphism data for osteonecrosis were obtained from the FinnGen public database R11 dataset,containing information on a total of 431 614 samples and 21 306 430 single nucleotide polymorphism loci,with 1 788 cases of osteonecrosis and 429 826 controls,with all participants being of European descent.Mendelian randomization analysis(inverse variance weighting method,MR-Egger method,and weighted median method)was performed by Rstudio software,and then the heterogeneity test,horizontal pleiotropy test and Steiger directionality test were performed to ensure the robustness and reliability of the results.RESULTS AND CONCLUSION:(1)Sixteen blood metabolites were identified as having a significant causal relationship with osteonecrosis(Pinverse variance weighting<Pfalse discovery rate<0.05).(2)Eight blood metabolites increased the risk of osteonecrosis(including four known metabolites and four unknown metabolites),specifically pantothenate,beta-hydroxyisovalerate,hippurate,salicyluric glucuronide,X-08766,X-11452,X-12776 and X-14662.(3)Eight blood metabolites could reduce the risk of osteonecrosis(six known metabolites and two unknown metabolites),including cortisol,1-palmitoylglycerol(1-monopalmitin),pyroglutamyl glycine,2-stearoylglycerophosphocholine,p-cresol sulfate,ergothioneine,X-06307,X-12092.(4)The above results suggest that there is a causal relationship between 16 blood metabolites and osteonecrosis,which is expected to be a potential target for intervention in the occurrence and treatment of osteonecrosis in the future.(5)Despite the lack of relevant data from large-scale Asian populations at present,this study provides important reference value for the field of osteonecrosis in China based on European population data.In the future,domestic medical workers may be able to achieve precise intervention for osteonecrosis by regulating metabolite levels.In addition,based on the results of this study,relevant researchers can further explore the mechanism of action of metabolites in the treatment of osteonecrosis with traditional Chinese medicine,which not only helps to deepen the understanding of traditional Chinese medical therapies but also promotes the progress of integrated traditional Chinese and Western medicine research,driving the development of personalized treatment plans that are more suitable for the characteristics of the Chinese population.

Osteoarthritis (OA), a highly prevalent degenerative joint disease worldwide, is defined by articular cartilage degradation, abnormal bone remodeling, and persistent chronic inflammation. It severely compromises patients’ quality of life, and currently, there is no radical cure. Abnormal mechanical stress is widely regarded as a core driver of OA pathogenesis, and the exploration of mechanical signal perception and transduction mechanisms has become crucial for deciphering OA’s pathophysiological processes. Piezo1, a key mechanosensitive cation channel belonging to the Piezo protein family, has recently gained significant attention due to its pivotal role in mediating cellular responses to mechanical stimuli in joint tissues. This review systematically examines Piezo1’s expression patterns, regulatory mechanisms, and pathological functions in OA, with a particular focus on its dual roles in modulating chondrocyte homeostasis and bone metabolism disorders, while also delving into the underlying molecular signaling pathways and potential therapeutic implications. Piezo1, consisting of approximately 2 500 amino acids and forming a unique trimeric propeller-like structure, is widely expressed in chondrocytes, osteocytes, mesenchymal stem cells, and synovial cells. It exhibits permeability to cations such as Ca2+, K+, and Na+, and directly responds to membrane tension changes induced by mechanical stimuli like fluid shear stress and mechanical overload. In OA patients and animal models, Piezo1 expression is significantly upregulated, especially in cartilage regions subjected to abnormal mechanical stress (e.g., human temporomandibular joint cartilage). This overexpression is closely associated with aggravated cartilage degeneration, increased chondrocyte apoptosis, accelerated cellular senescence, and intensified inflammatory responses. Mechanical overload and pro-inflammatory cytokines (e.g., IL-1β) are key inducers of Piezo1 upregulation: IL-1β activates the PI3K/AKT/mTOR signaling pathway to enhance Piezo1 expression, forming a pathogenic positive feedback loop that inhibits chondrocyte autophagy, promotes apoptosis, and further accelerates joint degeneration. Mechanistically, Piezo1 mediates OA progression through multiple interconnected pathways. When activated by mechanical stress, Piezo1 triggers excessive Ca2+ influx, leading to endoplasmic reticulum stress (ERS) and mitochondrial dysfunction, which directly induce chondrocyte apoptosis. This process involves the activation of downstream signaling cascades such as cGAS-STING and YAP-MMP13/ADAMTS5. YAP, a transcriptional regulator, upregulates the expression of matrix metalloproteinase 13 (MMP13) and aggrecanase (ADAMTS5), thereby accelerating cartilage matrix degradation. Additionally, Piezo1-driven Ca2+ overload promotes the accumulation of reactive oxygen species (ROS) and upregulates senescence markers (p16 and p21), accelerating chondrocyte senescence via the p38MAPK and NF-κB pathways. Senescent chondrocytes secrete senescence-associated secretory phenotype (SASP) factors (e.g., IL-6, IL-1β), further amplifying joint inflammation. In terms of bone metabolism, Piezo1 maintains joint homeostasis by promoting the differentiation of fibrocartilage stem cells into chondrocytes and balancing bone formation and resorption through regulating the FoxC1/YAP axis and RANKL/OPG ratio. Therapeutically, targeting Piezo1 shows promising potential. Preclinical studies have demonstrated that Piezo1 inhibitors (e.g., GsMTx4) can reduce joint damage and alleviate pain in OA mice. Simultaneously, siRNA-mediated co-silencing of Piezo1 and TRPV4 (another mechanosensitive channel) decreases intracellular Ca2+ concentration, inhibits chondrocyte apoptosis, and promotes cartilage repair. Conditional knockout of Piezo1 using Gdf5-Cre transgenic mice alleviates cartilage degeneration in post-traumatic OA models by downregulating MMP13 and ADAMTS5 expression. Despite existing challenges, such as off-target effects of inhibitors, inefficient local drug delivery, and interindividual genetic variability, strategies like developing selective Piezo1 antagonists, optimizing targeted nanocarriers, and combining Piezo1-targeted therapy with physical therapy provide viable avenues for clinical translation. The authors propose that Piezo1 serves as a critical therapeutic target for OA, and future research should focus on deciphering its context-dependent regulatory networks, developing tissue-specific intervention strategies, and validating their efficacy and safety in clinical trials to address the unmet medical needs of OA patients.

ObjectiveTo investigate whether anti-programmed death-1 (PD-1) monoclonal antibody can enhance the efficacy and safety of argon-helium cryoablation combined with targeted therapy in patients with unresectable hepatocellular carcinoma (uHCC) aged 60 years or older. MethodsA retrospective analysis was performed for the clinical data of 124 patients with advanced uHCC aged 60 years or older who were treated at The Fifth Medical Center of Chinese PLA General Hospital from January 2013 to September 2024. After propensity score matching, 57 patients received cryoablation combined with targeted therapy (double combination group), while 57 received cryoablation combined with targeted therapy and anti-PD-1 monoclonal antibody (triple combination group). The indicators for efficacy assessment included objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and the incidence rate of adverse events. The Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used to plot survival curves, and the Log-rank test was used for comparison between groups. A Cox proportional-hazards regression model analysis was used to investigate the influencing factors for survival prognosis. ResultsThe triple combination group had a significantly higher ORR than the double combination group (59.6% vs 29.8%, χ2=9.083, P=0.003), while there was no significant difference in DCR between the two groups (87.7% vs 77.2%, χ2=1.516, P=0.218), and compared with the double combination group, the triple combination group had significantly longer median PFS (9.1 months vs 4.8 months, χ2=7.813, P=0.005) and median OS (26.1 months vs 13.6 months, χ2=14.199, P<0.001). The multivariate Cox proportional-hazards regression model analysis showed that triple combination treatment was an independent influencing factor for PFS (hazard ratio [HR]=0.52, 95% confidence interval [CI]: 0.35 — 0.78, P=0.001) and OS (HR=0.32, 95%CI: 0.20 — 0.51, P<0.001). There was no significant difference in the incidence rate of adverse events between the two groups (P>0.05). ConclusionTriple combination treatment with argon-helium cryoablation, targeted therapy, and anti-PD-1 monoclonal antibody can significantly improve survival benefits in uHCC patients aged 60 years or older, with a controllable safety profile.
