This study explored the prescription pattern of traditional Chinese medicine(TCM) in the treatment of hypertensive left ventricular hypertrophy(LVH), so as to provide a relevant theoretical basis for the clinical diagnosis and treatment of hypertensive LVH. The study systematically searched the databases of CNKI, Wanfang, VIP, and SinoMed to screen out the qualified literature on TCM treatment of hypertensive LVH and used Microsoft Excel 2021 to establish the relevant prescription database. It also counted the frequency, property, flavor, and meridian affiliation of TCM in the prescriptions and classified their efficacy. The study used Lantern 5.0 and Rstudio software to analyze the hidden structural models and association rules of the high-frequency TCM with a frequency of >3.50% and adopted Origin 2024 software to visualize the data, so as to explore the prescription pattern of TCM in treating hypertensive LVH. The results showed that a total of 128 TCM prescriptions were included, involving 163 TCM with a total frequency of 1 242. The high-frequency TCM included Salviae Miltiorrhizae Radix et Rhizoma, Uncariae Ramulus Cum Uncis, Gastrodiae Rhizoma, Poria, and Chuanxiong Rhizoma, with the main efficacy from blood-activating and stasis-resolving herbs, tonic herbs, and liver-calming and wind-extinguishing herbs. The latent structure analysis(LSA) identified 10 latent variables, 20 latent classes, 7 comprehensive clustering models, and 23 core prescriptions. It was speculated that the common syndromes of hypertensive LVH included blood stasis obstructing the collaterals, ascending hyperactivity of liver Yang, Yin deficiency with Yang hyperactivity, and intermingled phlegm and blood stasis. The association rule analysis yielded 33 strong association rules, with the highest comprehensive association rule being Gastrodiae Rhizoma→Uncariae Ramulus Cum Uncis. Hypertensive LVH is characterized by asthenia in origin and asthenia in superficiality, with Yin deficiency and Qi deficiency as the origin and blood stasis and phlegm as the superficiality. Clinical treatment focuses on activating blood circulation, resolving stasis, tonifying Qi, and nourishing Yin, combined with syndrome-specific therapies such as calming wind and stopping convulsions, clearing heat, eliminating dampness and resolving phlegm, and promoting diuresis and reducing swelling.

Ferroptosis, a programmed cell death modality discovered and defined in the last decade, is primarily induced by iron-dependent lipid peroxidation. At present, it has been found that ferroptosis is involved in various physiological functions such as immune regulation, growth and development, aging, and tumor suppression. Especially its role in tumor biology has attracted extensive attention and research. Breast cancer is one of the most common female tumors, characterized by high heterogeneity and complex genetic background. Triple negative breast cancer (TNBC) is a special type of breast cancer, which lacks conventional breast cancer treatment targets and is prone to drug resistance to existing chemotherapy drugs and has a low cure rate after progression and metastasis. There is an urgent need to find new targets or develop new drugs. With the increase of studies on promoting ferroptosis in breast cancer, it has gradually attracted attention as a treatment strategy for breast cancer. Some studies have found that certain compounds and natural products can act on TNBC, promote their ferroptosis, inhibit cancer cells proliferation, enhance sensitivity to radiotherapy, and improve resistance to chemotherapy drugs. To promote the study of ferroptosis in TNBC, this article summarized and reviewed the compounds and natural products that induce ferroptosis in TNBC and their mechanisms of action. We started with the exploration of the pathways of ferroptosis, with particular attention to the System X_c^--cystine-GPX4 pathway and iron metabolism. Then, a series of compounds, including sulfasalazine (SAS), metformin, and statins, were described in terms of how they interact with cells to deplete glutathione (GSH), thereby inhibiting the activity of glutathione peroxidase 4 (GPX4) and preventing the production of lipid peroxidases. The disruption of the cellular defense against oxidative stress ultimately results in the death of TNBC cells. We have also our focus to the realm of natural products, exploring the therapeutic potential of traditional Chinese medicine extracts for TNBC. These herbal extracts exhibit multi-target effects and good safety, and have shown promising capabilities in inducing ferroptosis in TNBC cells. We believe that further exploration and characterization of these natural compounds could lead to the development of a new generation of cancer therapeutics. In addition to traditional chemotherapy, we discussed the role of drug delivery systems in enhancing the efficacy and reducing the toxicity of ferroptosis inducers. Nanoparticles such as exosomes and metal-organic frameworks (MOFs) can improve the solubility and bioavailability of these compounds, thereby expanding their therapeutic potential while minimizing systemic side effects. Although preclinical data on ferroptosis inducers are relatively robust, their translation into clinical practice remains in its early stages. We also emphasize the urgent need for more in-depth and comprehensive research to understand the complex mechanisms of ferroptosis in TNBC. This is crucial for the rational design and development of clinical trials, as well as for leveraging ferroptosis to improve patient outcomes. Hoping the above summarize and review could provide references for the research and development of lead compounds for the treatment for TNBC.

Parkinson's disease(PD)is a neurodegenerative disorder whose core pathological feature is the abnormal accumulation of pathological α-synuclein(α-syn)in the brain,but there are rare clinical therapeutic modalities that target this.As a hot research topic in recent years,meningeal lymphatic vessels(MLVs)play an important role in central nervous system fluid(CNS)drainage,and can promote the exocytosis and clearance of metabolic wastes such as α-syn from the brain.Regulating the morphology and function of MLVs to promote α-syn exocytosis is likely to become an influential direction for future intervention in PD research and provide new approaches for the clinical therapy of PD.In this article,we will overview 3 aspects of the structure and function of MLVs,the role of MLVs in PD,and the strategy of targeting MLVs to treat PD.

Objective:To evaluate the effects and underlying mechanisms of preoperative intestinal microbiota modulation on the recovery of prolonged postoperative ileus(PPOI)in gastric cancer patients with sarcopenia Methods:Skeletal muscle mass(SMM)was assessed using bioelectrical impedance analysis(BIA),and the skeletal muscle index(SMI)was calculated.A total of 156 gastric cancer patients with sarcopenia who underwent surgery at the Department of Gastrointestinal Surgery,Liyang People's Hospital,from January 2022 to December 2024 were randomly assigned to either the control group or the experimental group.The control group received conventional prehabilitation interventions,including nutritional support,respiratory function training,and physical exercise.The experimental group received probiotic-based intestinal microbiota modulation in addition to conventional prehabilitation interventions.Postoperative recovery indicators,including time to first flatus,incidence of postoperative complications,length of hospital stay,and hospitalization costs,were compared between the two groups.Results:Among the 156 sarcopenic gastric cancer patients,121 were male,and 35 were female.Statistically significant differences were observed between the two groups in terms of time to first flatus,incidence of postoperative complications,and length of hospital stay(P<0.05).Postoperative complications occurred in 38 patients(24.3%),with 10 cases(6.4%)in the experimental group and 28 cases(17.9%)in the control group.The time to first flatus in the experimental group was significantly shorter than in the control group(48.0 hours vs 72.0 hours,P<0.001).Conclusion:Preoperative intestinal microbiota modulation significantly reduces the incidence of PPOI and postoperative complications in gastric cancer patients with low SMI,thereby promoting postoperative gastrointestinal function recovery.

Objective To investigate the regulatory effect of Dendrobium nobile Lindl alkaloids(DNLA)on the proliferation,migration,and epithelial-mesenchymal transition(EMT)of HLEB3 cells induced by TGF-β2.Methods HLEB3 cells were cultivated in vitro and classified into the control group(DZ),the model group(TGF-β2),and the treatment group(TGF-β2+DNLA).TGF-β2 induced the EMT process of HLEB3 cells.Changes in cell morphology were observed through an inverted microscope.Cell proliferation,apoptosis,and migration were detected by CCK-8 assay,scratch test,and Transwell assay.The total RNAs of the samples were extracted for transcriptome analysis.Bioinformatics processing was employed to obtain relevant information on gene expression differences at the transcriptional level,biological processes,and related signaling pathways.The Western blot(WB)technique was utilized to detect EMT-related proteins to elucidate the mechanism of action of DNLA on lens epithelial cells.Results The study revealed that 10 μg/ml DNLA was suitable for the growth of HLEB3 cells.After 48 hours of the scratch test,the migration rate of the TGF-β2+DNLA group significantly decreased(P<0.01).The Transwell results indicated that the cell migration ability of the TGF-β2+DNLA group was notably weakened(P<0.05).Through bioinformatics,it was discovered that the prevention and treatment of posterior capsular opacification(PCO)by DNLA might be associated with cell junctions,cytoskeleton construction,and fibronectin binding.The pathogenesis of PCO may be related to multiple signaling pathways,including the TGF-β signaling pathway,TNF signaling pathway,and PI3K-Akt signaling pathway.Simultaneously,DNLA could reduce the expression levels of FNI,Smad2/3,and α-SMA proteins and increase the expression of E-cadherin protein.This indicates that DNLA can alleviate abnormal proliferation,migration,and EMT of lens epithelial cells by enhancing intercellular adhesion junctions and weakening cell migration ability,thereby playing a role in preventing and treating posterior capsular opacification.Conclusions DNLA can significantly inhibit the abnormal proliferation and migration of HLEB3 cells,alleviate the EMT process induced by TGF-β2,and prevent and control the occurrence of posterior capsular opacification and other ocular diseases.The mechanism of action might be related to the intervention of the TGF-β/smad signaling pathway and fibrosis proteins such as ZO-1 and E-cadherin.

OBJECTIVE: To investigate the clinicopathological features and prognosis of urinary bladder urothelial carcinoma (UBUC) with incidental prostate cancer (IPCa). METHODS: We retrospectively analyzed the clinicopathological features of 65 cases of UBUC and 38 cases of UBUC + IPCa after radical cystoprostatectomy (RCP) from January 2017 to February 2020. We compared their expressions of the immunohistochemical markers androgen receptor (AR) and (human epidermal growth factor receptor 2,HER2) between the two groups of patients, and analyzed their clinicopathological characteristics by chi-square test and their survival rates using the Kaplan-Meier method and log-rank test. RESULTS: The detection rate of UBUC + IPCa was 16.5%, and that of clinically significant IPCa was 39.5%, with preoperative PSA≥4 μg/L in 23.7% of the patients. Compared with the patients with UBUC, most of the UBUC + IPCa cases had no smoking history (73.8% vs 92.1%, P = 0.024), and fewer had histological variants (43.1% vs 10.5%, P = 0.003). The incidence rate of vascular invasion was significantly higher in the UBUC than in the UBUC + IPCa group (49.2% vs 21.1%, P = 0.005), and so was the rate of advanced cases (67.7% vs 31.6%, P<0.001). In comparison with the patients of the UBUC group, those of the UBUC + IPCa group showed remarkably higher expressions of AR (9.2% vs 31.6%, P = 0.004) and HER2 (43.1% vs 71.1%, P = 0.006). The mean overall survival time was longer in the UBUC + IPCa than in the UBUC group (48.8 mo ［95% CI: 2.5－42.6 mo］ vs 39.9 mo ［95% CI: 2.8－34.5 mo］), but with no statistically significant difference between the two groups (P = 0.608). CONCLUSION Standardized sampling of prostate samples after RCP helps to improve the detection rate of IPCa. Preoperative level of PSA is not a good predictor of IPCa. Few patients with UBUC + IPCa have a history of cigarette smoking, and the predominant histological type of the malignancy is high-grade invasive urothelial carcinoma, which is not significantly different from UBUC in prognosis. The expressions of HER2 and AR are significantly higher in UBUC + IPCa than in UBUC, suggesting that UBUC + IPCa may benefit from HER2- and AR-targeted therapy.

Objective To explore the effects of electroacupuncture on motor function in Parkinson's disease(PD)model mice and NLRP3 inflammasome-related proteins in the midbrain substantia nigra(SN).Methods C57BL/6 mice were assigned to three groups according to the random number table method:control group,model group,and electroacupuncture(EA)group,12 mice per group.The PD model was reproduced by intragastric administration of rotenone solution 10 mg/(kg·d).EA group was administered at the three selected points,"Fengfu"(GV16),"Taichong"(LR3),and"Zusanli"(ST36),with a treatment cycle of 2 weeks.The control and model groups took the same time synchronous fixation operation for the control variable.Behavioral scores and open field tests were used to detect the exercise ability of mice in each group.Tyrosine hydroxylase(TH)and α-synuclein(α-syn)in the midbrain SN of mice in all groups were measured with an immunohistochemistry test.NLRP3 and cysteinyl aspartate specific proteinase-1(Caspase-1)protein expression levels in the midbrain SN of mice in the three groups were measured using Western blotting,and interleukin-1β(IL-1β)content was determined with an enzyme-linked immunosorbent assay.Results Compared to the control group,the behavioral scores of the mice in the model group were higher(P<0.01).Compared to the model group,the behavioral scores of the mice in the EA group were lower(P<0.01).Compared to the control group,the time ratio of the relative rest state of the mice in the model group(<100 mm/s)increased significantly(P<0.01),while the time ratio of the slow motion(100～200 mm/s)and time ratio of the fast motion(>200 mm/s)state decreased significantly(P<0.01).Compared to the model group,the time ratio spent in the relative rest state of mice in the EA group decreased significantly(P<0.01),while the time ratio of the slow motion state and time ratio of the fast motion state and movement rate increased significantly(P<0.01).Compared to the control group,the TH expression level decreased in the SN in the model group(P<0.01),while α-syn increased(P<0.01).Compared to the model group,the TH expression level in the EA group increased(P<0.05),while α-syn decreased(P<0.05).Compared to the control group,the protein expressions of NLRP3 and Caspase-1 in the SN of the model group increased(P<0.01);compared to the model group,the expressions of NLRP3 and Caspase-1 in the SN of the midbrain of mice decreased after EA treatment(P<0.01).Compared to the control group,IL-1β in the SN of the mouse midbrain increased in the model group(P<0.01).Compared to the model group,IL-1β decreased in the EA group(P<0.05).Conclusion This experiment shows that stimulation of EA in"Fengfu","Taichong",and"Zusanli"can effectively reduce abnormal aggregation of the PD marker α-syn,increase TH expression,and enhance the motor dysfunction of PD model mice.The molecular mechanism is related to the regulation of the expression of NLRP3,Caspase-1,and IL-1β of inflammasome-related pathways.
