BACKGROUND:The repair process of myocardial injury involves complex cellular and molecular mechanisms,especially mitochondrial calcium homeostasis,macrophage autophagy and pyroptosis pathways.Traditional Chinese medicine(TCM)has shown significant clinical efficacy in improving myocardial injury,but its mechanism of action needs to be thoroughly investigated. OBJECTIVE:To investigate the role of mitochondrial calcium homeostasis-mediated macrophage autophagy and pyroptosis pathways in myocardial injury,and to summarize the progress of TCM in this field. METHODS:A computerized search was performed for relevant literature from the database inception to March 2024 in the Web of Science,PubMed and CNKI.The search terms were"mitochondrial calcium homeostasis,macrophage autophagy,macrophage pyroptosis,traditional Chinese medicine,myocardial injury,myocardial injury reperfusion"in Chinese and English.Through literature review,we analyzed the relationship between mitochondrial calcium homeostasis and macrophage autophagy and pyroptosis,explored the mechanism of their roles in myocardial injury,and summarized the pathways of multi-targeted,multi-pathway effects of TCM. RESULTS AND CONCLUSION:The maintenance of mitochondrial calcium homeostasis has been found to be closely related to the normal function of cardiomyocytes.Macrophages can participate in the repair process of myocardial injury through autophagy and pyroptosis pathways.Autophagy contributes to cell clearance and regulation of inflammatory response,while pyroptosis affects myocardial repair by releasing inflammatory factors.TCM regulates mitochondrial calcium homeostasis and macrophage function through multiple mechanisms.For example,astragalosid regulates calcium homeostasis by lowering mitochondrial membrane potential and inhibiting cytochrome C,and epimedium glycoside plays a role in reducing β-amyloid deposition.In addition,herbal compounds and single drugs promote myocardial repair by activating or inhibiting specific signaling pathways,such as PI3K/AKT and nuclear factor-κB signaling pathways.Future studies should focus on the interactions between mitochondrial calcium homeostasis,autophagy and pyroptosis pathways,as well as how TCM can exert therapeutic effects through these pathways to provide new strategies and drugs for the treatment of myocardial injury.

BACKGROUND:Estrogen receptor α can act as an upstream protein to regulate the expression and phosphorylation level of adenosine monophosphate-activated protein kinase(AMPK).Activation of the estrogen receptor α-AMPK signaling pathway promotes osteogenic proliferation and differentiation.OBJECTIVE:To explore the molecular mechanism of estrogen receptor α regulating AMPK and its effect on osteoblast proliferation and differentiation at osteoblast cell line and molecular biology levels.METHODS:(1)The passaged MC3T3-E1 mouse embryonic osteoblasts were divided into three groups:blank control group,mock group(transfected with pCDNA3.1 control plasmid),and estrogen receptor α group(transfected with pCDNA3.1-estrogen receptor α overexpression plasmid),and RT-qPCR and western blot methods were used to detect the hepatic kinase B1,CaMKKβ,and AMPKα1 mRNA,protein and phosphorylation levels.(2)ChIP-qPCR was used to demonstrate that estrogen receptor α interacts with the hepatic kinase B1 promoter.Dual luciferase assay was used to demonstrate that estrogen receptorα interacts with the hepatic kinase B1 promoter region to activate its transcriptional expression.(3)The cells were divided into three groups:mock+shNC group,estrogen receptor α+shNC group,and estrogen receptor α+shLKB1 group.Changes in the expression levels of hepatic kinase B1,phosphorylated hepatic kinase B1,and phosphorylated AMPKα1 proteins in the cells were detected by western blot.(4)The cells were divided into four groups:mock group,estrogen receptor α group,estrogen receptor α+5 μmol/L Compound C(AMPK inhibitor)group,and estrogen receptor α+10 μmol/L Compound C group.The expression of proteins related to the AMPK signaling pathway and related to osteogenesis and osteoinductivity were detected by western blot method.Cells were transfected for 24 hours and then subjected to osteogenic induction for 14 days.Alkaline phosphatase staining was performed and cell viability in each group was detected.Mineralized nodule formation was detected by alizarin red staining at 21 days of osteogenic induction.(5)The cells were transfected and pretreated with different concentrations of AMPK inhibitor in corresponding groups,and cell viability was detected by cell counting kit 8.RESULTS AND CONCLUSION:(1)Estrogen receptor α activates the AMPK signaling pathway in MC3T3-E1 cells.(2)Estrogen receptor α promotes liver kinase B1 transcription and mediates AMPK signaling pathway activation.(3)Estrogen receptor α promotes the proliferation and differentiation of MC3T3-E1 cells by activating the AMPK signaling pathway,and the expression of AMPKα1,p-AMPKα,osteoprotegerin,osteopontin,and Runx2 proteins was down-regulated under the intervention of AMPK inhibitor,and the viability of osteoblasts was decreased.(4)To conclude,estrogen receptor α activates the AMPK signaling pathway by acting on liver kinase B1 promoter,promotes osteoblast proliferation and osteogenic differentiation,and prevents osteoporosis.

OBJECTIVE To investigate the mechanism through which Chaixian Huashen decoction(CXHSD)ameliorates lipopolysaccharide(LPS)-induced acute lung injury(ALI)in mice.METHODS Component analysis:the components of CXHSD extract were analyzed via ultra-high performance liquid chromatography-high resolution mass spectrometry(UPLC-Q-Exactive HFX).Network pharma-cology analysis was conducted to predict the potential active components and underlying therapeutic targets of CXHSD for ALI treatment.① Animal experiment:mice were randomly divided into the normal control group,model(LPS)group,model+dexamethasone(DEX)4 mg·kg-1 group,model+CXHSD 10 g·kg-1 group,and model+CXHSD 20 g·kg-1 group.Except for the normal control group,ALI was induced in all the mice by intratracheal instillation of LPS.Model+CXHSD groups received daily intra-gastric administration of corresponding treatments for 7 consecutive days.The model+DEX group was administered saline intragastrically for the initial 5 d,followed by DEX for the next 2 d.ALI was induced by intratracheal instillation of LPS 5 mg·kg-1 1 h after the 6th administration of CXHSD/DEX.24 h after modeling,the severity of pulmonary edema was assessed using the wet to dry weight(W/D)ratio,and hematoxylin-eosin(HE)staining was used to evaluate histopathological damage.The levels of myeloperoxidase(MPO),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),IL-1β in lung tissue homogenates and serum were measured by enzyme-linked immunosorbent assay(ELISA).The total protein concentration in bronchoalveolar lavage fluid(BALF)was measured by bicinchoninic acid(BCA)assay.Immunohistochemistry and Western blotting were used to assess the expression levels of toll-like receptor 4(TLR4),myeloid differentiation primary response 88(MyD88),zonula occludens-1(ZO-1)and occludin,as well as the phosphorylation level of nuclear factor-kappa B p65(NF-κB p65).② Cell experiment:RAW264.7 cells were divided into the cell control group,LPS 1 mg·L-1 group,LPS 1 mg·L-1+DEX 1 mg·L-1 group,and LPS 1 mg·L-1+CXHSD 50,100 and 200 mg·L-1 groups.After 24 h of culture,the nitric oxide(NO)content was measured with the nitrate reductase method,the levels of TNF-α,IL-1 β and IL-6 in the cell supernatants of each group were detected by ELISA.RESULTS Network pharmacology analysis indicated that CXHSD might alleviate ALI through the NF-κB pathway.① Com-pared with the normal control group,the W/D ratio was elevated,pathological injuries aggravated(such as alveolar wall thickening,inflammatory infiltration,and alveolar congestion),histopathological damage pronounced,MPO activity increased,and total protein concentrations in BALF raised in the model group,in which levels of TNF-α,IL-6 and IL-1 β in both lung tissue and serum became higher.Concur-rently,LPS increased the expressions of p-NF-κB p65,TLR4 and MyD88,but reduced the expressions of ZO-1 and occludin.Compared with the model group,model+CXHSD groups had their pulmonary edema and lung pathological injury ameliorated as evidenced by alleviated alveolar wall thickening,inflammatory infiltration and alveolar congestion.The levels of MPO,TNF-α,IL-1 β and IL-6 in both lung tissue and serum,and the total protein concentrations in BALF were significantly decreased in the model+CXHSD groups.Additionally,the expressions of TLR4,MyD88,and p-NF-κB p65 were significantly downregulated,while those of ZO-1 and occludin were prominently upregulated.② Compared with the cell control,the levels of TNF-α,IL-1 β,IL-6 and NO in the supernatant of RAW264.7 cells were signifi-cantly increased in the LPS group.Compared with the LPS group,in the supernatant of RAW264.7 cells treated with LPS+CXHSD at 100 mg·L-1,there was no significant difference in TNF-α levels.However,in the other groups treated with LPS+CXHSD,the levels of TNF-α,IL-1 β,IL-6,and the content of NO were significantly reduced.CONCLUSION CXHSD can alleviate LPS-induced ALI by inhibiting the TLR4/NF-κB pathway,attenuating inflammation,and preserving pulmonary barrier integrity.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective To explore the relationship between non-high density lipoprotein cholesterol(non-HDL-C)level and leptomeningeal collateral circulation in patients with acute middle cerebral artery occlusion.Methods A total of 85 patients with first-onset acute cerebral infarction with middle cerebral artery M1 segment occlusion were enrolled.According to the results of DSA,LMC circulation was assessed by American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology Collateral Circulation Assess-ment System.All patients were assigned to better LMC circulation group(score 2～4,n = 30)and worse LMC circulation group(score 0～1,n = 55),and the levels of non-HDL-C were compared between the two groups.Results The levels of LDL-C and non-HDL-C in worse LMC circulation group were significantly higher than those of the better LMC circulation group(P = 0.026,P = 0.010).non-HDL-C was an independent risk factor for the worse LMC circulation(OR = 3.019,95%CI:1.053～8.658,P = 0.04).LMC circulatory score of patients was negatively correlated with the levels of non-HDL-C level(r =-0.228,P = 0.036).The AUC of non-HDL-C predicted for the worse LMC circulation was 0.638(95%CI:0.521～0.755,P = 0.036).Conclusions non-HDL-C in patients with acute cerebral infarction was significantly related to worse LMC circulation,and was a risk factor for worse LMC circulation.It is suggested that the higher expression of non-HDL-C could be used to predict worse LMC circulation as a serological indicator.
