ObjectiveTo elucidate the efficacy connotation of Shudi Qiangjin pills (SQP) against liver and kidney deficiency in steroid-induced osteonecrosis of femoral head (SONFH) from the perspective of the "disease-syndrome-formula" association and to clarify the underlying mechanisms based on in vivo and in vitro experiment validation. MethodsThe chemical components and the corresponding putative targets of SQP were collected from the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0, the Encyclopedia of Traditional Chinese Medicine (ETCM) v2.0, and HERB databases. The SONFH-related genes were identified based on the differential expression profiles of peripheral blood of patients with SONFH compared to the healthy volunteers, and the disease phenotype-related targets were collected from the TCMIP v2.0 database. Then, the interaction network of "SONFH-related genes and candidate targets of SQP" was constructed based on "gene-gene interaction information", and the major network targets were screened by calculating the topological characteristic values of the network followed by the functional mining according to the Kyoto Encyclopedia of Genes and Genomes (KEGG) database and the SoFDA database. After that, the SONFH rat model was prepared by lipopolysaccharide combined with methylprednisolone injection, and 2.5, 5, 7.5 g·kg-1 SQP (once per day, equivalent to 1, 2, and 3 times the clinical equivalent dose, respectively) or 7.3×10-3 g·kg-1 of alendronate sodium (ALS, once per week, equivalent to the clinical equivalent dose) was given for 8 weeks. The effect characteristics of SQP and ALS in the treatment of SONFH were evaluated by micro-computed tomography scanning, hematoxylin and eosin staining, alkaline phosphatase (ALP) staining, immunohistochemical staining, enzyme-linked immunosorbent assay, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)staining, and a comparative efficacy analysis was conducted with ALS. In addition, SONFH cell models were prepared by dexamethasone stimulation of osteoblasts, and the intervention was carried out with the medicated serum of SQP at the aforementioned three doses. Cell counting kit-8, ALP staining, ALP activity assay, alizarin red staining, and flow cytometry were employed to investigate the regulatory effect of SQP on osteoblasts. The expression levels of osteogenesis-related proteins and key factors of the target signaling axis were detected by quantitative real-time polymerase chain reaction and Western blot. ResultsThe network analysis results demonstrated that the candidate targets of SQP primarily exerted their therapeutic effects through key signaling pathways, including phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt), lipid metabolism and atherosclerosis, prolactin, chemokines, and neurotrophic factors pathways. These pathways were significantly involved in critical biological processes such as muscle and bone metabolism and the regulation of the "neuro-endocrine-immune" network, thereby addressing both modern medical symptoms (e.g., delayed skeletal maturation and recurrent fractures) and traditional Chinese medicine (TCM) symptoms (e.g., fatigue, aversion to cold, cold limbs, and pain in the limbs and joints in patients with SONFH characterized by liver and kidney deficiency syndrome. Among these pathways, the PI3K/Akt signaling pathway exhibited the highest degree of enrichment. The in vivo experimental results demonstrated that starting from the 4th week after modeling, the modeling group exhibited a significant reduction in body weight compared to the control group (P<0.05). After six weeks of treatment, all dosage groups of SQP showed significantly higher body weights compared to the model group (P<0.01). Compared with the normal group, the model group exhibited significant decreases in bone mineral density (BMD), bone volume fraction (BV/TV), trabecular number (Tb.N), osteocalcin (OCN), alkaline phosphatase (ALP) levels in femoral head tissue, and serum bone-specific alkaline phosphatase (BALP) (P<0.01), along with significant increases in trabecular separation (Tb.Sp), empty lacunae rate in tissue, and apoptosis rate (P<0.01). In comparison to the model group, the SQP intervention groups showed significant improvements in BMD, BV/TV and Tb.N (P<0.01), significant reductions in Tb.Sp, empty lacunae rate and apoptosis rate (P<0.05), and significant increases in protein levels of OCN and ALP as well as BALP content (P<0.05). The in vitro experimental results revealed that all dosage groups of SQP medicated serum showed no toxic effects on osteoblast. Compared with the normal group, the model group displayed significant suppression of osteoblast proliferation activity, ALP activity, and calcified nodule formation rate (P<0.01), significant decreases in mRNA transcription levels of OCN and Runt-related transcription factor 2 (RUNX2) (P<0.01), significant reductions in protein content of osteopontin (OPN), typeⅠ collagen (ColⅠ)A1, B-cell lymphoma-2 (Bcl-2), PI3K, and phosphorylated (p)-Akt (P<0.01), and a significant increase in apoptosis rate (P<0.01). Compared with the model group, the SQP medicated serum intervention groups exhibited significant increases in proliferation activity, ALP activity, calcified nodule formation rate, mRNA transcription levels of OCN and RUNX2, and protein content of OPN, ColⅠA1, Bcl-2, PI3K, and p-Akt (P<0.05), along with a significant decrease in apoptosis rate (P<0.01). ConclusionSQP can effectively reduce the disease severity of SONFH with liver and kidney deficiency syndrome and improve bone microstructure, with the therapeutic effects exhibiting a dose-dependent manner. The mechanism may be related to its regulation of key processes such as muscle and bone metabolism and the correction of imbalances in the "neuro-endocrine-immune" network, thereby promoting osteoblast differentiation and inhibiting osteoblast apoptosis. The PI3K/Akt signaling axis is likely one of the key pathways through which this formula exerts its effects.

ObjectiveTo investigate the molecular mechanism by which Yifei Xuanfei Jiangzhuo prescription regulates the nuclear factor-κB (NF-κB)/NOD-like receptor protein 3 (NLRP3) signaling pathway to improve neuronal function in vascular dementia (VaD) rats. MethodsA VaD model was established by intermittently clamping the bilateral common carotid arteries (CCA) combined with bilateral vascular occlusion (2-VO). Eighty-four SD rats were randomly divided into a blank group, sham group, model group, piracetam group (0.2 g·kg-1), and low-, medium-, and high-dose Yifei Xuanfei Jiangzhuo prescription groups (6.09, 12.18, and 24.36 g·kg-1). Drug administration began on day 7 after surgery, once daily for 28 consecutive days. Behavioral experiments were used to evaluate learning and spatial memory. Hematoxylin-eosin (HE) staining was applied to observe pathological morphological changes in the CA1 region of the hippocampus. Transmission electron microscopy was used to examine the ultrastructure of hippocampal neurons. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) was used to detect neuronal apoptosis in the CA1 region. Immunohistochemistry was performed to determine the positive expression rate of neuronal nuclear antigen (NeuN). Immunofluorescence single staining was used to assess nuclear expression of NF-κB p65 in brain tissue. Western blot was used to detect the protein expression levels of inhibitor of κB kinase (IKK), NF-κB p65, NLRP3, Caspase-1, apoptosis-associated speck-like protein (ASC), and interleukin-1β (IL-1β). ResultsCompared with the blank group, the model group showed a significant reduction in platform-crossing frequency (P0.01), aggravated hippocampal injury, a significant increase in neuronal apoptosis (P0.05), decreased NeuN positivity in the CA1 region (P0.05), increased nuclear expression of NF-κB p65 (P0.05), and significantly elevated expression of p-IKK, p-NF-κB p65, NLRP3, cleaved Caspase-1, ASC, and cleaved IL-1β (P0.05). Compared with the model group, all drug-treated groups improved learning and spatial memory in VaD rats, alleviated hippocampal pathological injury and neuronal apoptosis, and protected neuronal ultrastructure. Yifei Xuanfei Jiangzhuo prescription at doses of 12.18 and 24.36 g·kg-1 reduced hippocampal expression levels of p-IKK, p-NF-κB p65, NLRP3, Caspase-1, ASC, and cleaved IL-1β in VaD rats (P0.05), showing dose-dependent inhibition of the NF-κB/NLRP3 signaling pathway. ConclusionYifei Xuanfei Jiangzhuo prescription may exert neuroprotective effects by regulating the NF-κB/NLRP3 signaling pathway, thereby reducing neuroinflammation and inhibiting hippocampal neuronal apoptosis.

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.

By consulting relevant literature of ancient herbal books and processing specifications, this paper made a systematic research and analysis of Ostreae Concha, including the name, producing area, harvesting, quality, historical evolution of processing, relevant processing specifications, modern processing technology, and changes in chemical composition and pharmacological effects before and after processing, in order to provide documentary evidence for the research on processing technology and the establishment of quality standards. According to the textual research, it is known that Ostreae Concha has a long history of being used in medicine, and there have been many aliases and local names in each historical period. Shennong's Classic of the Materia Medica(Shennong Bencaojing) began to use Muli as the correct name, which has continued to use to today, and there were also aliases such as Muge, Zuogu Muli and Haoke. Ostreae Concha has a wide range of localities and irregular harvesting periods. The ancients believed that its left shell was of superior quality, but this has not been seen in modern. And there were many kinds of processing methods of Ostreae Concha, such as grinding, roasting, calcining, frying, simmering, quenching and so on, and the calcining was still in use. The different editions of Chinese Pharmacopoeia from 1963 to 2020 contain only calcined Ostreae Concha, and the local processing specifications mainly include three kinds of processed products(calcined products, salt-soaked products and vinegar-soaked products). Modern processing research mainly focuses on process optimization, changes in chemical composition and pharmacological effects, and the research methods are relatively single. Overall, there are currently issues such as inconsistent processing standards, unclear process parameters and imperfect quality standards, which are not conducive to the quality control and standardized clinical use of Ostreae Concha. Therefore, it is necessary to further investigate the pharmacological substance basis of Ostreae Concha and its processed products in order to elucidate the processing mechanism, standardize the processing technology and improve the quality standard.

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 explore the mechanism by which the ethanol extract of Epimedium brevicornu (EEBM) intervenes in mesenchymal adipose-derived stem cells (ADSCs) to delay aging in castrated rats. MethodsForty-five 3-month-old SPF female SD rats were ovariectomized and randomly divided into model group, ADSCs treatment group, and ADSCs groups treated with low, medium, and high concentrations of EEBM (1, 50, 100 μg·L-1), referred to as the AE low, medium, and high concentration groups, with 9 rats in each group. After tail vein injection of 200 μL of the corresponding stem cell suspension, aging-related indicators including cyclin-dependent kinase inhibitor (p21), tumor suppressor gene (p53), interleukin-6 (IL-6), interleukin-8 (IL-8), superoxide dismutase (SOD), malondialdehyde (MDA), B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), cysteine-aspartic acid protease-3 (Caspase-3), and lipofuscin were measured using enzyme-linked immunosorbent assay (ELISA) and Western blot. ResultsCompared with the model group, the IL-6 content in the AE low, medium, and high concentration groups was significantly decreased (P<0.05). Lipofuscin, MDA, and IL-8 levels in the ADSCs treatment group and AE low, medium, and high concentration groups were significantly reduced (P<0.01), while SOD content was significantly increased (P<0.05, P<0.01). Compared with the ADSCs treatment group, lipofuscin and IL-8 levels in the AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01). The MDA content was significantly decreased in the AE medium concentration group (P<0.01). Compared with the model group, protein levels of p21, p53, Bax, and Caspase-3 in the ADSCs treatment group and AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01), while the Bcl-2 protein level was significantly increased (P<0.01). Compared with the ADSCs treatment group, protein levels of p21, p53, Bax, and Caspase-3 in the AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01), and the Bcl-2 protein level in the AE low concentration group was significantly increased (P<0.01). ConclusionThe results of this experiment show that EEBM-treated ADSCs or ADSCs may delay aging in castrated rats by inhibiting cell apoptosis, reducing cell cycle inhibitors and pro-inflammatory factors, enhancing antioxidant capacity, and reducing oxidative reactions. Moreover, EEBM-treated ADSCs demonstrate stronger anti-aging effects than ADSCs alone. This study provides experimental evidence supporting the clinical use of EEBM to intervene in ADSCs and delay aging.

Atopic dermatitis (AD) is a common pruritic and chronic inflammatory dermatosis in clinical practice and is one of the diseases responding specifically to traditional Chinese medicine (TCM). With the launch of biological agents and small molecule drugs and the development and implementation of guidelines of diagnosis and treatment, clinical pathways of treatment of moderate to severe AD, and consensus on the whole-process management of AD, the clinical efficacy of moderate to severe AD has been significantly improved. However, there are still many unmet clinical needs that require more effective methods to meet. In response to the Opinions of the CPC Central Committee and the State Council on Facilitating the Inheritance, Innovation, and Development of Traditional Chinese Medicine and the spirit of the National Conference on TCM, the China Association of Chinese Medicine organized more than 20 experts in TCM dermatology, Western medicine dermatology, interdisciplinary fields, and industries to discuss the difficulties and advantages of TCM in the treatment of AD. TCM treatment for AD can not only improve rash and relieve itching but also solve many concomitant syndromes. The abundant external treatment methods of TCM have advantages for different special populations and rash characteristics. The concept of treating disease before its onset in TCM is in line with the chronic disease management mode of prevention and treatment of atopic march and prevention of recurrence. In addition, TCM therapy can reduce the use of topical glucocorticoids and has good safety. Regarding the comorbidity of AD, equal emphasis on TCM and Western medicine and multidisciplinary joint treatment should be advocated to achieve maximum benefit for patients. The exchange of TCM and Western medicine has clarified the positioning and advantages of TCM intervention in AD, providing guidance for clinical and scientific research.
