OBJECTIVE To explore the influencing factors for successful detoxification in patients undergoing methadone maintenance therapy. METHODS A retrospective selection of 161 methadone maintenance therapy patients from the South Branch of Zhongshan Second People’s Hospital (including methadone maintenance treatment sites in Shiqi District, Xiqu District, Development Zone of Zhongshan City) from January 1, 2012, to January 1, 2025, was conducted as the study object. Data collected included patients’ sociodemographic information, drug abuse history, laboratory test results, medication records, etc. Patients were divided into the unsuccessful detoxification group and the successful detoxification group based on whether methadone detoxification was achieved. Univariate, univariate Cox regression, and multivariate Cox proportional hazards regression were used for influencing factor analysis, and the Kaplan-Meier method was employed for survival analysis. RESULTS Among the 161 methadone maintenance therapy patients, 96 were in the successful detoxification group and 65 in the unsuccessful detoxification group, yielding a successful detoxification rate of 59.63%. Multivariate Cox proportional hazards regression analysis revealed that age, registered residence status, age at first drug use, and duration of drug abuse were key influencing factors for successful detoxification in methadone maintenance therapy patients (P<0.05). Specifically, the successful detoxification rate for patients with Zhongshan local registered residence was 8.364 times higher than that for patients with non-local registered residence; for every 1-year increase in patient age, the successful detoxification rate decreased by 22.7%; for every 1-year increase in age at first drug use, the successful detoxification rate rose by 33.4%; and for every 1-year increase in duration of drug abuse, the successful detoxification rate increased by 33.5%. Survival analysis showed that the successful detoxification rate in the methadone low-dose group (≤30.8 mg) was significantly higher than that in the methadone high-dose group (>30.8 mg) (P=0.015), and the successful detoxification rate in the population with Zhongshan local registered residence was significantly higher than that in those with non-local registered residence (P<0.001). CONCLUSIONS Age, registered residence status, age at first drug use, and duration of drug abuse are key influencing factors for successful detoxification in patients undergoing methadone maintenance therapy, and the last methadone dose may be associated with successful detoxification.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

This article systematically analyzed the historical evolution of the origin, scientific name, producing area, quality evaluation, harvesting and processing, and other aspects of Quisqualis Fructus by consulting the ancient materia medica, medical books, prescription books, local literature and combining with the modern literature and standards, summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes, in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research, Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty, and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty, which has been consistently used throughout subsequent dynasties, and there were also aliases such as Junziren, Sijunzi, and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica, a plant belonging to the family Combretaceae. In modern times, its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007, the Flora of China(English edition) designated Q. indica var. villosa as a synonym of Q. indica. Today, the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records, the producing areas of Quisqualis Fructus were Guangdong, Hong Kong, Macao, Guangxi, Hainan, Sichuan and Fujian, and then gradually expanded to Yunnan, Taiwan, Jiangxi and Guizhou. Since the Song dynasty, two major production regions have gradually emerged in Sichuan, Chongqing and Fujian. Currently, it is primarily cultivated in Chongqing, Guangxi and other areas, with Chongqing yielding the highest output. Since modern times, superior quality has been defined by large size, a purple-black surface, plump grains, and a yellowish-white kernel. According to ancient herbal records, the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar, mostly used raw after shelling or with the shell intact, it underwent processing methods such as cleaning, slicing, mixing, steaming, roasting, stewing, and frying. Currently, the harvesting period is autumn, followed by sun-drying or low-heat drying, with processing methods including cleaning, stir-frying, and stewing. In ancient and modern literature, the records of the properties, functions and indications of Quisqualis Fructus are basically the same, that is, sweet in taste, warm in nature, predominantly non-toxic, belonging to the spleen and stomach meridians. It possesses effects of insecticide, decontamination and invigorating spleen for ascariasis, enterobiasis, abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations, limiting use for those with spleen-stomach deficiency-cold, refraining from drinking hot tea during medication, and avoiding excessive intake. Based on the textual research, it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements, and the raw products is recommended for medicinal use if not specified.

ObjectiveTo optimize and validate the optimal sequential alcohol-water extraction process of modified Banxia Xiexintang(MBXT) based on pharmacodynamic evaluation, combined with the G1-entropy weight method and Box-Behnken response surface methodology, and to systematically and comprehensively analyze the material basis of this formula, providing a scientific basis for its quality control and industrial production. MethodsRats were randomly divided into the normal group, model group, metformin group, and MBXT water extraction, water extraction and ethanol precipitation, sequential ethanol-water extraction groups. Except for the normal group, a polycystic ovary syndrome with insulin resistance(PCOS-IR) model was established in all rats via a high-fat diet combined with letrozole induction. Enzyme-linked immunosorbent assay(ELISA) biochemical assay kits and hematoxylin-eosin(HE) staining were used to compare sex hormone levels in serum and ovarian histopathology, thereby screening extraction process routes. Based on this, a comprehensive score was constructed using the G1-entropy weight method based on the transfer rates of index components(berberine hydrochloride and baicalin) and the dry extract rate. Box-Behnken response surface methodology was then utilized to optimize the extraction process parameters. Finally, the chemical constituents of the sample from the optimal process were qualitatively analyzed by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap mass spectrometry(UPLC-Q-Orbitrap-MS). ResultsPharmacodynamic findings revealed that compared with the normal group, serum testosterone(T) and luteinizing hormone(LH) levels were significantly elevated in the model group, while estradiol(E2) and follicle-stimulating hormone(FSH) levels were significantly decreased(P<0.01), with polycystic changes observed in ovarian tissues. Compared with the model group, all treatment groups significantly reversed the changes in sex hormone levels, with the sequential ethanol-water extraction group showing the optimal effect in improving the aforementioned indicators and pathological morphology, followed by subsequent process optimization. The optimized process involved adding 12 times the amount of 70% ethanol for extracting twice, each lasting 120 min, and adding 12 times the amount of water for extracting thrice, each lasting 90 min. Validation test results showed that under optimal process conditions, the average transfer rates of berberine hydrochloride and baicalin were 76.05% and 93.38%, respectively. MS analysis identified a total of 377 compounds, including 112 flavonoids, 41 terpenoids, 28 organic acids, 22 coumarins, and 8 alkaloids, while elucidating the cleavage patterns of key components. ConclusionThe optimized sequential ethanol-water extraction process is stable and feasible, effectively preserving the material basis of MBXT for treating PCOS-IR. It further clarifies the main chemical composition of this formula, providing a scientific basis for the development and quality control of its preparations.

ObjectiveTo evaluate the therapeutic effects of modified Banxia Xiexintang(MBXT) on polycystic ovary syndrome with insulin resistance(PCOS-IR) rats and reveal its potential mechanisms based on the integrated analysis of transcriptomics and metabolomics. MethodsFemale SD rats were selected, and a PCOS-IR model was established by intragastric administration of letrozole combined with a high-fat diet for 21 days. The modeled rats were randomly divided into the model group, MBXT low-, medium-, and high-dose groups(6.62, 13.23, 26.46 g·kg-1), and metformin group(0.158 g·kg-1), with a normal group set up separately. After 14 days of administration, the estrous cycle was observed, ovarian morphology was examined by hematoxylin-eosin(HE) staining, and the levels of testosterone(T), estradiol(E2), follicle-stimulating hormone(FSH), and luteinizing hormone(LH) in serum were detected by enzyme-linked immunosorbent assay(ELISA). Serum metabolites and ovarian tissue gene expression were detected using ultra-performance liquid chromatography-quadrupole-electrostatic orbitrap mass spectrometry(UPLC-Q-Orbitrap-MS) and RNA-Seq technology, respectively, followed by multi-omics integrated analysis. ResultsPharmacodynamic findings revealed that all MBXT dose groups could reversed abnormal estrous cycles in PCOS-IR rats, improve polycystic ovarian lesions, and normalize dysregulated serum hormone levels(T, LH, E2, FS, P<0.05, P<0.01). Metabolomic analysis revealed that compared with the model group, MBXT reversed 278 differential metabolites such as estrone and S-formylglutathione, mainly involving pathways such as steroid hormone biosynthesis, glutathione metabolism, and lipid peroxidation regulation. Transcriptomic analysis identified 434 differentially expressed genes, and enrichment analysis revealed that MBXT significantly regulated lipid peroxidation defense systems, including glutathione metabolism, peroxisome function, and fatty acid metabolism, thereby intervening in ferroptosis processes. It also engaged in inflammation-related pathways such as the chemokine signaling pathway. Integrated analysis revealed that both metabolomics and transcriptomics co-enriched metabolic pathways associated with ferroptosis and fatty acid metabolism. And key Hub genes[such as Ras-related C3 botulinum toxin substrate 2 gene(Rac2) and Fas ligand gene(Faslg)] showed significant correlations with differential metabolites. ConclusionMBXT can effectively ameliorate reproductive dysfunction and metabolic disorders in PCOS-IR rats. Its mechanism may be related to remodeling the immune-metabolism network, particularly by regulating MHC-mediated immune responses, inhibiting local ovarian ferroptosis, and enhancing steroid hormone synthesis pathways.

ObjectiveTo investigate the mechanism of modified Banxia Xiexintang(MBXT) in improving ovarian dysfunction in polycystic ovary syndrome with insulin resistance(PCOS-IR) rats by inhibiting ferroptosis through the adenosine monophosphate(AMP)-activated protein kinase(AMPK)/fatty acid synthase(FASN)/glutathione peroxidase 4(GPX4) signaling pathway. MethodsSeventy-six female SD rats were randomly divided into a normal group(n=13) and a modeling group(n=63). The modeling group established a PCOS-IR model by intragastric administration of letrozole combined with a high-fat diet for 21 days. After successful modeling, these rats were randomly divided into the model group, MBXT low-, medium-, and high-dose groups(6.62, 13.23, 26.46 g·kg-1), metformin group(0.158 g·kg-1), and high-dose of MBXT combined with ferroptosis inducer Erastin group(15 mg·kg-1), with 10 rats in each group. After 14 days of intervention, ovarian pathological morphology was observed by hematoxylin-eosin(HE) staining, the mitochondrial ultrastructure of granulosa cells was observed by transmission electron microscopy(TEM), ovarian reactive oxygen species(ROS) levels were detected by dihydroethidium(DHE) probe, biochemical methods were used to detect Fe2+, malondialdehyde(MDA), glutathione(GSH) and other indicators in ovarian tissues, serum sex hormone and insulin levels were measured by enzyme-linked immunosorbent assay(ELISA), and the protein expressions of AMPK, FASN, acyl-CoA synthetase long-chain family member 4(ACSL4), GPX4, and solute carrier family 7 member 11(SLC7A11) in ovarian tissues were detected by Western blot. ResultsCompared with the normal group, the model group showed polycystic changes in the ovaries, with atrophy of mitochondria in granulosa cells and increased membrane density. Serum levels of testosterone(T), luteinizing hormone(LH), and insulin were significantly increased(P<0.01). The levels of ROS, MDA, 4-hydroxynonenal(4-HNE), and Fe2+ in ovarian tissues were significantly elevated(P<0.01), while adenosine triphosphate(ATP), GSH, and reduced nicotinamide adenine dinucleotide phosphate (NADPH) levels were significantly decreased(P<0.01). The phosphorylation levels of AMPK and acetyl-CoA carboxylase (ACC), as well as the protein expressions of SLC7A11, GPX4, and ferroptosis suppressor protein 1(FSP1) were significantly downregulated(P<0.01), whereas the expressions of FASN, ACSL4, and nuclear receptor coactivator 4(NCOA4) were significantly upregulated(P<0.01). Compared with the model group, MBXT intervention at various doses improved the above pathological changes and biochemical indicators in a dose-dependent manner, with the high-dose group showing the most significant effect(P<0.01). Compared with the MBXT high-dose group, the high-dose of MBXT combined with ferroptosis inducer Erastin group restored ovarian ferroptosis characteristics in rats, with increased ROS and lipid peroxidation products, and altered expressions of key proteins(P<0.05, P<0.01). ConclusionMBXT can effectively improve ovarian function and metabolic disorders in PCOS-IR rats. Its mechanism may be related to activating the AMPK/ACC signaling pathway, downregulating FASN and ACSL4 to reduce lipid peroxidation substrates, and restoring glucose-6-phosphate dehydrogenase/phosphoglycerate dehydrogenase(G6PD/PHGDH) metabolic flux to enhance the GPX4/FSP1 antioxidant defense system, thereby inhibiting ferroptosis in ovarian granulosa cells.

ObjectiveTo explore the effect of serum containing Zhenwutang on myocardial mast cell apoptosis induced by angiotensin Ⅱ (AngⅡ) and the mechanism of the correlation between apoptosis and mitochondrial autophagy. MethodsIn this experiment, AngⅡ and serum containing Zhenwutang with different concentrations were used to interfere with H9C2 cardiomyocytes for 24 h, and the survival rate of H9C2 cardiomyocytes was detected by cell counting kit-8 (CCK-8) to screen the optimal concentration for the experiment. Enzyme-linked immunosorbent assay (ELISA) was used to detect the content of B-type natriuretic peptide (BNP) in cell culture supernatant, and immunofluorescence was used to detect the cell surface area to verify the construction of the myocardial mast cell model. Subsequently, the experiment was divided into a blank group (20% blank serum), a model group (20% blank serum + 5×10-5 mol·L-1 AngⅡ), low-, medium-, and high-dose (5%, 10% and 20%) serum containing Zhenwutang groups, an autophagy inhibitor group (1×10-4 mol·L-1 3-MA), and autophagy inducer group (1×10-7 mol·L-1 rapamycin). The apoptosis level of H9C2 cells and the changes of mitochondrial membrane potential were detected by flow cytometry. The lysosomal probe (Lyso Tracker) and mitochondrial probe (Mito Tracker) co-localization was employed to detect autophagy. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect Caspase-3, Caspase-9, B-cell lymphoma 2 (Bcl-2), Bcl-2-related X protein (Bax), and cytochrome C (Cyt C) in apoptosis-related pathways and the relative mRNA expression of ubiquitin ligase (Parkin), phosphatase and tensin homolog (PTEN)-induced kinase 1 (PINK1), and p62 protein in mitochondrial autophagy-related pathways. Western blot was used to detect cleaved Caspase-3, cleaved Caspase-9, Bax, Bcl-2, and Cyt C in apoptosis-related pathways, phosphorylated ubiquitin ligase (p-Parkin), phosphorylated PTEN-induced kinase 1 (p-PINK1), p62, and Bcl-2 homology domain protein Beclin1 in mitochondrial autophagy-related pathways, and the change of microtubule-associated protein 1 light chain 3 (LC3) Ⅱ/Ⅰ ratio. ResultsCCK-8 showed that when the concentration of AngⅡ was 5×10-5 mol·L-1, the cell activity was the lowest, and there was no cytotoxicity. At this concentration, the surface area of cardiomyocytes was significantly increased (P<0.01), and the content of BNP in the supernatant of culture medium was significantly increased (P<0.05). Therefore, AngⅡ with a concentration of 5×10-5 mol·L-1 was selected for the subsequent modeling of myocardial mast cells. Compared with the blank group, the model group and the autophagy inhibitor 3-MA group had a significantly increased apoptosis rate (P<0.01) and significantly decreased mitochondrial membrane potential (P<0.01). The results of immunofluorescence co-localization showed that compared with the blank group, the model group had a significantly decreased number of red and green fluorescence spots. The results of Real-time PCR showed that compared with that in the blank group, the relative mRNA expression of Bax, Caspase-3, Caspase-9, Cyt C, and p62 in the model group was significantly up-regulated (P<0.01), while the relative mRNA expression of Bcl-2, Parkin, and PINK1 was significantly down-regulated (P<0.01). In addition, the relative protein expression of Bax, cleaved Caspase-3, cleaved Caspase-9, Cyt C, and p62 was significantly up-regulated (P<0.01). The LC3Ⅱ/Ⅰ was significantly decreased, and the relative protein expression of Bcl-2, p-Parkin, p-PINK1, and Beclin1 was significantly down-regulated (P<0.01). Compared with the model group, the serum containing Zhenwutang groups and the autophagy inducer group had significantly decreased apoptosis rate (P<0.01), and the decrease ratio of mitochondrial membrane potential is significantly lowered (P<0.01) in a dose-dependent manner. Additionally, both red and green fluorescence spots became more in these groups. In the 3-MA group, the number of red and green fluorescence spots decreased significantly. The relative mRNA expression of Bax, Caspase-3, Caspase-9, Cyt C, and p62 was significantly down-regulated (P<0.05, P<0.01), while that of Bcl-2, Parkin, and PINK1 was significantly up-regulated (P<0.01). In the serum containing Zhenwutang groups, the relative protein expression levels of Bax, cleaved Caspase-3, cleaved Caspase-9, Cyt C, and p62 were significantly down-regulated (P<0.05,P<0.01). The LC3Ⅱ/Ⅰ was significantly increased, and the relative protein expression levels of Bcl-2, p-Parkin, p-PINK1, and Beclin1 were significantly up-regulated (P<0.01). ConclusionThe serum containing Zhenwutang can reduce the apoptosis of myocardial mast cells and increase mitochondrial autophagy. This is related to the inhibition of intracellular Bax/Bcl-2/Caspase-3 apoptosis pathway and regulation of Parkin/PINK1 mitochondrial autophagy pathway.

Objective:To evaluate the clinical outcomes of combined complete preservation of chordal structure mitral valve replacement (C-MVR) with total anatomical arterial myocardial revascularization (TACR) in coronary patients with moderate-to-severe or severe ischemic mitral regurgitation (IMR).Methods:This is a retrospective multi-center case series study. Data were retrospectively collected from 127 patients with coronary artery disease with moderate to severe or severe IMR who received TACR with C-MVR from July 2015 to April 2024 in 13 hospitals in China. There were 90 males and 37 females, aged (56.5±10.7) years (range: 33 to 74 years). Perioperative data and follow-up data including left ventricular ejection fraction, left ventricular end-diastolic diameter, and patency rate of arterial grafts of patients were collected. Comparisons were made using paired sample t-test or χ2 test. Results:In this cohort of 127 patients, 67 underwent concurrent tricuspid valve repair. During surgery, 113 grafts of the left internal mammary artery (LIMA), 127 grafts of the left radial artery, 80 grafts of the right radial artery, and 110 grafts of the right internal mammary artery (RIMA) were harvested. The number of the distal anastomosis was 4.2±0.4 (range: 3 to 5). The aortic cross-clamp time and cardiopulmonary bypass time were (97.5±23.4) minutes (range: 90 to 161 minutes) and (145.4±19.2) minutes (range: 101 to 210 minutes), respectively. There was one operative death. Intraoperative placement of an intra-aortic balloon pump was performed in 21 patients to improve the left ventricular ejection. No sternal ischemic occurred. All patients completed follow-up, with a mean follow-up period of (64.3±7.5) months (range: 4 to 110 months). No major cerebrovascular events occurred during the follow-up period, and all patients survived. Left ventricular ejection fraction improved postoperatively (55.0%±5.3% vs. 41.0%±15.3%, t=17.23, P<0.01). The proportion of patients with New York Heart Association functional class ≤2 increased postoperatively (23.6% (30/127) vs. 87.3% (110/126), χ2=103.77, P<0.01). The proportion of patients with Canadian Cardiovascular Society Angina Classification ≤3 decreased postoperatively (4.8% (6/126) vs. 78.7% (100/127), χ2=142.19, P<0.01). The left ventricular end-diastolic diameter decreased postoperatively ((5.70±4.50) cm vs. (6.10±0.23) cm, t=12.15, P<0.01). Coronary multi-detector computed tomography angiography (MDCTA) follow-up was conducted for (60.5±11.7) months (range: 6 to 109 months) postoperatively. MDCTA confirmed the patency rates of the grafts: 96.4% (108/112) for the LIMA grafts, 88.9% (112/126) for the left radial artery grafts, 93.7% (74/79) for the right radial artery grafts, and 90.9% (100/110) for the free RIMA grafts. No significant differences in graft patency rates were observed between the arterial grafts ( χ2=5.24, P=0.155). Conclusion:The results of this multi-centre study demonstrate satisfactory mid-term results of C-MVR with TACR for the treatment of coronary artery disease with moderate to severe or severe IMR.

ObjectiveTo investigate the mechanism of Acanthopanacis Senticosi Radix et Rhizoma seu Caulis extract (ASH) in treating Parkinson's disease (PD) in mice by Data-Independent Acquisition (DIA) proteomics. MethodsThe α-Synuclein (α-Syn) transgenic PD mice were selected as suitable models for PD, and they were randomly assigned into PD, ASH (61.25 mg·kg-1), and Madopar (97.5 mg·kg-1) groups. Male C57BL/6 mice of the same age were selected as the control group, with eight mice in each group. Mice were administrated with corresponding drugs by gavage once a day for 20 days. The pole climbing time and the number of autonomic activities were recorded to evaluate the exercise ability of mice. Hematoxylin-eosin staining was employed to observe neuronal changes in the substantia nigra of PD mice. Immunohistochemistry (IHC) was employed to measure the tyrosine hydroxylase (TH) activity in the substantia nigra and assess the areal density of α-Syn in the striatum. DIA proteomics was used to compare protein expression in the substantia nigra between groups. IHC was utilized to validate key differentially expressed proteins, including Lactotransferrin, Notch2, Ndrg2, and TMEM 166. The cell counting kit-8 (CCK-8) method was used to investigate the effect of ASH on the viability of PD cells with overexpression of α-Syn. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the protein and mRNA levels of Lactotransferrin, Notch2, Ndrg2, and TMEM 166 in PD cells. ResultsCompared with the control group, the model group showed prolonged pole climbing time, diminished coordination ability, reduced autonomic activities (P<0.01), and reduced swelling neurons. Compared with the model group, ASH and Madopar reduced the climbing time, increased autonomic activities (P<0.01), and ameliorated neuronal damage. Compared with the control group, the model group showed a decrease in TH activity in the substantia nigra and an increase in α-Syn accumulation in the striatum (P<0.01). Compared with the model group, the ASH group showed an increase in TH activity and a reduction in α-Syn accumulation (P<0.05). DIA proteomics revealed a total of 464 differentially expressed proteins in the model group compared with the control group, with 323 proteins being up-regulated and 141 down-regulated. A total of 262 differentially expressed proteins were screened in the ASH group compared with the model group, including 85 proteins being up-regulated and 177 down-regulated. Kyoto encylopedia of genes and genomes (KEGG) pathway analysis indicated that ASH primarily regulated the Notch signaling pathway. The model group showed up-regulation in protein levels of Notch2, Ndrg2, and TMEM 166 and down-regulation in the protein level of Lactotransferrin compared with the control group (P<0.01). Compared with the model group, ASH down-regulated the protein levels of Notch2, Ndrg2, and TMEM 166 (P<0.05) while up-regulating the protein level of Lactotransferrin (P<0.01). The IHC results corroborated the proteomics findings. The cell experiment results showed that compared with the control group, the modeling up-regulated the mRNA and protein levels of Notch2, Ndrg2, and TMEM 166 (P<0.01), while down-regulating the mRNA and protein levels of Lactotransferrin (P<0.01). Compared with the model group, ASH reduced the mRNA and protein levels of Notch2, Ndrg2, and TMEM 166 (P<0.01), while increasing the mRNA and protein levels of Lactotransferrin (P<0.05, P<0.01). ConclusionASH may Synergistically inhibit the Notch signaling pathway and mitigate neuronal damage by down-regulating the expression of Notch2 and Ndrg2. Additionally, by up-regulating the expression of Lactotransferrin and down-regulating the expression of TMEM166, ASH can address brain iron accumulation, intervene in ferroptosis, inhibit mitophagy, and mitigate reactive oxygen species damage, thereby protecting nerve cells and contributing to the treatment of PD.
