摘要:
Abstract: The traditional herb Eleutherococcus henryi Oliv. is commonly used to treat inflammatory conditions including rheumatism, arthritis, and hepatitis, as well as mental fatigue and amnesia, according to traditional Chinese medicine (TCM) theory. Savinin is a natural lignan obtained from the roots of E. henryi. The present study was undertaken to determine whether savinin can relieve LPS-induced neuroinflammation and if so, what the mechanism is. Groups of male C57BL/6 mice were administered savinin (5, 10, 20 mg/kg) and DEX (10 mg/kg) by gavage once daily for a continuous 7 days. On the 5th day of continuous pre-administration, LPS (2.5 mg/kg) was injected into the lateral ventricles of the mice for modeling 48 h. We found that treatment with savinin decreased the levels of neuroinflammatory cytokines and histopathological alterations dramatically. Consequently, it improved the LPS-induced neuroinflammatory response in mice. Furthermore, savinin inhibited the up-regulated expression of related proteins in the activated MAPK/NF-κB and NLRP3 inflammasome signaling pathways caused by LPS. Docking studies demonstrated the binding of savinin to three receptors (MAPK, NF-κB and NLRP3) using a well-fitting mode. These findings suggest that savinin may suppress neuroinflammation induced by LPS in vivo via modulating MAPK/NF-κB and NLRP3 signaling pathways. Keywords: savinin; neuroinflammation; MAPK; NF-κB; NLRP3 inflammasome
摘要:
Trastuzumab (Tra), the first humanized monoclonal antibody that targets human epidermal growth factor receptor 2 (HER2), is commonly used alongside doxorubicin (Dox) as a combination therapy in HER2-positive breast cancer. Unfortunately, this leads to a more severe cardiotoxicity than Dox alone. NLRP3 inflammasome is known to be involved in Dox-induced cardiotoxicity and multiple cardiovascular diseases. However, whether the NLRP3 inflammasome contributes to the synergistic cardiotoxicity of Tra has not been elucidated. In this study, primary neonatal rat cardiomyocyte (PNRC), H9c2 cells and mice were treated with Dox (15mg/kg in mice or 1μM in cardiomyocyte) or Tra (15.75mg/kg in mice or 1μM in cardiomyocyte), or Dox combined Tra as cardiotoxicity models to investigate this question. Our results demonstrated that Tra significantly potentiated Dox-induced cardiomyocyte apoptosis and cardiac dysfunction. These were accompanied by the increased expressions of NLRP3 inflammasome components (NLRP3, ASC and cleaved caspase-1), the secretion of IL-β and the pronounced production of ROS. Inhibiting the activation of NLRP3 inflammasome by NLRP3 silencing significantly reduced cell apoptosis and ROS production in Dox combined Tra-treated PNRC. Compared with the wild type mice, the systolic dysfunction, myocardial hypertrophy, cardiomyocyte apoptosis and oxidative stress induced by Dox combined Tra were alleviated in NLRP3 gene knockout mice. Our data revealed that the co-activation of NLRP3 inflammasome by Tra promoted the inflammation, oxidative stress and cardiomyocytes apoptosis in Dox combined Tra-induced cardiotoxicity model both in vivo and in vitro. Our results suggest that NLRP3 inhibition is a promising cardioprotective strategy in Dox/Tra combination therapy.

摘要:
Geriatric Orthopaedic Surgery & Rehabilitation, Volume 14, Issue , January-December 2023. <br/>IntroductionOsteoporosis is a major cause of fractures and even life-threatening fractures in the elderly. Mind-body exercise is a beneficial intervention to improve flexibility, control body balance and reduce pain. We aimed to evaluate the effects of physical and mental exercise on osteoporosis in the elderly.MethodsRandomized controlled trials (RCTs) focusing on mind-body exercises for osteoporosis were included. Web of Science, PubMed, Science Direct, Medline, Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang were searched from inception to January 2023. Outcomes included bone mineral density (BMD), bone mineral content (BMC), body balance (BB), pain, indicators of bone metabolism (BMI), lower extremity function, fearing level, and quality of life (QOL). The quality of study reporting was rated by 2 reviewers independently, and Review Manager software (version 5.3) was used for meta-analysis.ResultsThirty-nine trials with 2325 participants were included. The pooled results showed that mind-body exercises have encouraging effect on elderly people with osteoporosis, especially in aspects of BMD, BMC, QOL, improving the function of lower extremity, reducing pain and fearing level. While, dance and eight-section brocade could not improve the quality of life,or dance and eight-section brocade have no effect on BMD.ConclusionsMind-body exercises may have potential efficacy for osteoporosis in the elderly. However, due to the poor methodological quality of the included trials, more clinical trials with precise methodological design and rigorous reporting are needed.
摘要:
Heterotopic ossification (HO), including hereditary and acquired HO, is the formation of extraskeletal bone in skeletal muscle and surrounding soft tissues. Acquired HO is often caused by range of motion, explosion injury, nerve injury or burns. Severe HO can lead to pain and limited joint activity, affecting functional rehabilitation and quality of life. Increasing evidence shows that inflammatory processes and mesenchymal stem cells (MSCs) can drive HO. However, explicit knowledge about the specific mechanisms that result in HO and related cell precursors is still limited. Moreover, there are no effective methods to prevent or reduce HO formation. In this review, we provide an update of known risk factors and relevant cellular origins for HO. In particular, we focus on the underlying mechanisms of MSCs in acquired HO, which follow the osteogenic program. We also discuss the latest therapeutic value and implications for acquired HO. Our review highlights the current gaps in knowledge regarding the pathogenesis of acquired HO and identifies potential targets for the prevention and treatment of HO.
摘要:
BACKGROUND: Doxorubicin (Dox), a chemotherapeutic agent known for its efficacy, has been associated with the development of severe cardiotoxicity, commonly referred to as doxorubicin-induced cardiotoxicity (DIC). The role and mechanism of action of phloretin (Phl) in cardiovascular diseases are well-established; however, its specific function and underlying mechanism in the context of DIC have yet to be fully elucidated. OBJECTIVE: This research aimed to uncover the protective effect of Phl against DIC in vivo and in vitro, while also providing a comprehensive understanding of the underlying mechanisms involved. METHODS: DIC cell and murine models were established. The action targets and mechanism of Phl against DIC were comprehensively examined by systematic network pharmacology, molecular docking, transcriptomics technologies, transcription factor (TF) prediction, and experimental validation. RESULTS: Phl relieved Dox-induced cell apoptosis in vitro and in vivo. Through network pharmacology analysis, a total of 554 co-targeted genes of Phl and Dox were identified. Enrichment analysis revealed several key pathways including the PI3K-Akt signaling pathway, Apoptosis, and the IL-17 signaling pathway. Protein-protein interaction (PPI) analysis identified 24 core co-targeted genes, such as Fos, Jun, Hif1a, which were predicted to bind well to Phl based on molecular docking. Transcriptomics analysis was performed to identify the top 20 differentially expressed genes (DEGs), and 202 transcription factors (TFs) were predicted for these DEGs. Among these TFs, 10 TFs (Fos, Jun, Hif1a, etc.) are also the co-targeted genes, and 3 TFs (Fos, Jun, Hif1a) are also the core co-targeted genes. Further experiments validated the finding that Phl reduced the elevated levels of Hif3a (one of the top 20 DEGs) and Fos (one of Hif3a's predicted TFs) induced by Dox. Moreover, the interaction between Fos protein and the Hif3a promoter was confirmed through luciferase reporter assays. CONCLUSION: Phl actively targeted and down-regulated the Fos protein to inhibit its binding to the promoter region of Hif3a, thereby providing protection against DIC.
摘要:
Syndecan-1 (SDC-1) was a critical membrane proteoglycan and an important component of the glycocalyx in endothelial cells, but its role in atherosclerosis remains unknown. This study attempted to investigate the role of SDC-1 in atherosclerotic-related endothelial cell injury. Bioinformatics analyzed the differential miRNAs between atherosclerosis and healthy. Subjects with coronary atherosclerosis, which were diagnosed with intravascular atherosclerosis (IVUS), were enrolled as non-vulnerable plaque and vulnerable plaque in Changsha Central Hospital. Human aortic endothelial cells (HAECs) were induced by oxidized low-density lipoprotein (ox-LDL) to construct an in vitro model. A dual luciferase reporter assay was applied to analyze the target between miR-19a-3p and SDC-1. The cell proliferation and apoptosis were detected by CCK8 and flow cytometry, respectively. SDC-1 and cholesterol efflux was determined by ELISA. The expression of ATPbinding cassette (ABC) transports A1 (ABCA1), miR-19a-3p, ABCG1 and SDC-1 genes were detected by RT-qPCR. The expressions of SDC-1, ABCA1, ABCG1, TGF-& beta;1, Smad3 and p-Smad3 proteins were detected by western blot. Our results found that miR-19a-3p was down-regulated in atherosclerosis. ox-LDL decreased miR-19a-3p expression, increased cholesterol efflux and the expression of ABCA1, ABCG1 and SDC-1 in HAECs. Vulnerable plaque tissues in patients with coronary atherosclerosis showed palpable fibrous necrosis and calcification with elevated blood SDC-1 levels. miR-19a-3p could bind to SDC-1. Overexpression of miR19a-3p promoted cell proliferation, inhibited apoptosis and cholesterol efflux, down-regulated the expression of SDC-1, ABCA1, ABCG1, TGF-& beta;1 and p-Smad3 proteins in ox-LDL-induced HAECs. In conclusion, miR19a-3p targeting SDC-1 inhibited the ox-LDL-induced activation of the TGF-& beta;1/Smad3 pathway in HAECs.

摘要:
Degeneration of the intervertebral disc is primarily caused by the loss of nucleus pulposus cells (NPCs) and extracellular matrix (ECM) (IDD). Bu-Shen-Huo-Xue-Fang (BSHXF), a traditional Chinese medicine decoction, has been used to treat IDD in clinical; nevertheless, the active components and underlying molecular mechanisms remain unknown. BSHXF improved IL-113 and H2O2 stimulation-induced injuries on NPCs by promoting cell viability, increasing ECM deposition, inhibiting cell senescence, and decreasing the levels of inflammatory factors. The active ingredients in BSHXF were identified by LC-MS/MS analysis; three active ingredients from the principal drugs, Aucubin, Tanshinol, and Tanshinone II A promoted NPC viability; and Aucubin and Tanshinol promoted NPC viability more. Aucubin and Tanshinol, respectively, improved H2O2 stimulation-induced injuries on NPCs by promoting cell viability, increasing ECM deposition, inhibiting cell senescence, and decreasing the levels of inflammatory factors. The activator of NF-cB and Wnt signaling pathways attenuated Aucubin and Tanshinol's protective effects by promoting ECM degradation and NPC senescence. Aucubin, Tanshinol, and Tanshinone II A were identified as the most potent compounds in BSHXF protection against degenerative changes in NPCs. The NF-cB and Wnt signaling pathways might be involved in the protective effects of Aucubin and Tanshinol against H2O2-induced degenerative changes.
摘要:
The study uses an LMJSS‐TMT‐UPLC‐MS method to spatially map amine metabolites to brain histopathological changes including neuron loss, glial cell activation, and neurogenesis. This integrated study explains the mechanisms of posttraumatic brain injury brain damage and repair. It also uncovers the therapeutic mechanisms of traditional Chinese medicine, Xuefu Zhuyu decoction. Abstract Introduction Spatial changes of amine metabolites and histopathology of the whole brain help to reveal the mechanism of traumatic brain injury (TBI) and treatment. Methods A newly developed liquid microjunction surface sampling–tandem mass tag–ultra performance liquid chromatography–mass spectrometry technique is applied to profile brain amine metabolites in five brain regions after impact‐induced TBI at the subacute stage. H&E, Nissl, and immunofluorescence staining are performed to spatially correlate microscopical changes to metabolic alterations. Then, bioinformatics, molecular docking, ELISA, western blot, and immunofluorescence are integrated to uncover the mechanism of Xuefu Zhuyu decoction (XFZYD) against TBI. Results Besides the hippocampus and cortex, the thalamus, caudate‐putamen, and fiber tracts also show differentiated metabolic changes between the Sham and TBI groups. Fourteen amine metabolites (including isomers such as L‐leucine and L‐isoleucine) are significantly altered in specific regions. The metabolic changes are well matched with the degree of neuronal damage, glia activation, and neurorestoration. XFZYD reverses the dysregulation of several amine metabolites, such as hippocampal Lys‐Phe/Phe‐Lys and dopamine. Also, XFZYD enhances post‐TBI angiogenesis in the hippocampus and the thalamus. Conclusion This study reveals the local amine‐metabolite and histological changes in the subacute stage of TBI. XFZYD may promote TBI recovery by normalizing amine metabolites and spatially promoting dopamine production and angiogenesis.

摘要:
Hepatic leukemia factor (HLF), a transcription factor, is dysregulated in many cancers. This study investigates the function of HLF in prostate cancer (PCa) and its relation to tensin 1 (TNS1). Clinical tissues were collected from 24 PCa patients. Duke University 145 (DU145) and PC3 cells overexpressing HLF were established. HLF signaling was downregulated in PCa tissues compared to adjacent tissues and in DU145 and PC3 cells compared to prostate epithelial cells RWPE-1 or prostate stromal cells (WPMY-1). PCa cell lines with overexpression of HLF had reduced proliferative, migratory, and invasive activity, increased apoptosis, and cell mitosis mostly in the G0/G1 phase. HLF induced the TNS1 transcription to activate the p53 pathway. Depletion of TNS1 reversed the anti-tumor effects of HLF on PCa cells and tumor growth and metastasis in vivo. In summary, our findings suggest that HLF suppressed PCa progression by upregulating TNS1 expression and inducing the p53 pathway activation, which might provide insights into novel strategies for combating PCa.
摘要:
Background: Intracranial teratomas or other cystic lesions with atypical imaging manifestations can still be frequently seen clinically. The specific reasons for unusual imaging manifestations need to be further explored.Observation(s): A case of adult teratoma in the posterior fossa with unusual imaging manifesta-tions was reported. The chemical composition of its cystic fluid was quantitatively detected, and in vitro imaging simulation experiments were performed on some fluid substances with similar cystic fluid properties to explore the reasons for special imaging manifestations. The content of inorganic substances and protein in the cystic fluid were both low, with no melanin detected. In vitro experiments revealed that MR T1 signals could increase with protein content rising and changes in MR T2 signals presented no obvious correlation with it. CT values increased gradually with protein concentration rising. The substances with similar viscosity had similar CT values, whereas substance viscosity showed no significant correlation with changes in MR signals.Conclusion: The abnormality of imaging manifestations cannot be confirmed as the result of "high protein content", nor can it be simply attributed to bleeding. Further research is required for the impact of the combination of paramagnetic particles and biofluid on imaging.

摘要:
Essential proteins play important roles in the development and survival of organisms whose mutations are proven to be the drivers of common internal diseases having higher prevalence rates. Due to high costs of traditional biological experiments, an improved Transfer Neural Network (TNN) was designed to extract raw features from multiple biological information of proteins first, and then, based on the newly-constructed Transfer Neural Network, a novel computational model called TNNM was designed to infer essential proteins in this paper. Different from traditional Markov chain, since Transfer Neural Network adopted the gradient descent algorithm to automatically obtain the transition probability matrix, the prediction accuracy of TNNM was greatly improved. Moreover, additional antecedent memory coefficient and bias term were introduced in Transfer Neural Network, which further enhanced both the robustness and the non-linear expression ability of TNNM as well. Finally, in order to evaluate the identification performance of TNNM, intensive experiments have been executed based on two well-known public databases separately, and experimental results show that TNNM can achieve better performance than representative state-of-the-art prediction models in terms of both predictive accuracies and decline rate of accuracies. Therefore, TNNM may play an important role in key protein prediction in the future.

摘要:
Diabetes mellitus (DM) is a chronic metabolic disorder characterized by hyperglycemia resulting from insulin secretion defects or insulin resistance. The global incidence of DM has been gradually increasing due to improvements in living standards and changes in dietary habits, making it a major non-communicable disease that poses a significant threat to human health and life. The pathogenesis of DM remains incompletely understood till now, and current pharmacotherapeutic interventions are largely inadequate, resulting in relapses and severe adverse reactions. Although DM is not explicitly mentioned in traditional Chinese medicine (TCM) theory and clinical practice, it is often classified as “Xiaoke” due to similarities in etiology, pathogenesis, and symptoms. With its overall regulation, multiple targets, and personalized medication approach, TCM treatment can effectively alleviate the clinical manifestations of DM and prevent or treat its complications. Furthermore, TCM exhibits desirable therapeutic effects with minimal side effects and a favorable safety profile. This paper provides a comprehensive comparison and contrast of Xiaoke and DM by examining the involvement of TCM in their etiology, pathogenesis, treatment guidelines, and other relevant aspects based on classical literature and research reports. The current TCM experimental research on the treatment of DM by lowering blood glucose levels also be generalized. This innovative focus not only illuminates the role of TCM in DM treatment, but also underscores the potential of TCM in DM management.

摘要:
[ABSTRACT] Male infertility is a significant cause of psychosocial and marital distress in approximately 50% of couples who are unable to conceive, with male factors being the underlying cause. Guijiajiao (Colla Carapacis et Plastri, CCP) is a Traditional Chinese Medicine commonly used to treat male infertility. The present study aimed to investigate the potential mechanisms underlying the preventive effects of CCP on male infertility. An infertile male rat model was established using cyclophosphamide (CTX), and CCP was administered for both treatment and prevention. Fecal microbiota transplantation (FMT) was also performed to explore the role of gut microbiota in the CCP-mediated prevention of male infertility in rats. Sperm motility and concentration were determined using a semiautomatic sperm classification analyzer. Subsequently, histopathological analysis using HE staining was performed to examine the changes in the small intestine and testis. Moreover, the serum levels of lipopolysaccharide (LPS) and testosterone were measured by ELISA. In addition, immunohistochemistry was conducted to detect CD3 expression in the small intestine, while RT-qPCR was employed to assess the expressions of interleukin-1 beta (IL-10), cluster of differentiation 3 (CD3), Monocyte chemoattractant protein-1 (MCP-1), and C-X-C motif chemokine ligand 10 (CXCL-10) in the small intestine and epididymis. Finally, gut microbiota was analyzed by 16S rRNA sequencing. CCP improved sperm motility, number, and concentration in CTX-induced infertile male rats. CCP increased the serum testosterone level, inhibited the immune cell infiltration of the intestinal lamina propria, and promoted the aggregation of CD3+ T cells in CTX-induced male infertility rats. CCP also inhibited the expressions of MCP-1, CXCL-10, and IL-10 in the epididymis of male infertility rats. At the genus level, CTX led to a reduction in the abundance of Lactobacillus, Clostridia_UCG.014, and Romboutsia in the intestinal tract of rats. In contrast, CCP decreased the abundance of Ruminococcus and increased the abundance of Romboutsia in infertile male rats. Additionally, FMT experiments proved that the gut microbiota of CCP-treated rats facilitated testicular tissue recovery and spermatogenesis while also reducing the serum LPS level in infertile male rats. CCP improves the spermatogenic ability of infertile male rats by restoring gut microbiota diversity and inhibiting epididymal inflammation.

摘要:
Disorders of central nervous system (CNS) disorders are considered serious health issues. The most common CNS diseases include neurodegenerative diseases, mental disorders, demyelinating disease, ischemia-reperfusion injury, and neuroinflammation. As a natural phenolic compound, hesperidin is a flavanone glycoside with various biological effects. Increasing evidence show that the growth of CNS diseases is hindered by hesperidin. Here, we have reviewed the related literature on neuropharmacological mechanisms for the preventive and therapeutic effects of hesperidin on CNS diseases. Several cellular and animal models have been developed to evaluate the underlying neuropharmacological mechanisms of hesperidin. Additionally, clinical evidence has confirmed its neuroprotective function. Hesperidin exerts its neuroprotective properties by decreasing neuro-inflammatory and apoptotic pathways. Hesperidin function has been studied in preclinical models for CNS diseases, but little is known about its definite effect in humans. Hesperidin can effectively alleviate depression and improve cognition and memory. It is urgent to explore and discover clinical trials for further confirmation of the neuroprotective efficacy of hesperidin and to evaluate its safety profile.
摘要:
BACKGROUND: The efficacy of acupoint application in the treatment of ulcerative colitis (UC) is still controversial. The purpose of this study is to systematically evaluate the clinical efficacy and safety of acupoint application in the treatment of ulcerative colitis. METHODS: The databases of China National Knowledge Infrastructure (CNKI), Chinese Biology Medicine (CBM), VIP, Wanfang, Embase, PubMed, the Cochrane Library and Web of Science were searched. The time limit was from the establishment of the database to July 2022. The published randomized controlled trials of acupoint application in the treatment of UC were analyzed by meta-analysis and trial sequential analysis. RESULTS: A total of 13 studies were included, with a total sample size of 878 cases. Compared with conventional western medicine, acupoint application can effectively improve the effective rates of clinical comprehensive (risk ratio [RR] 1.13, 95% confidence interval [CI] 1.06-1.20, P = .0003), syndrome (RR 1.13, 95% CI 1.03-1.24, P = .009), and interleukin-4 (IL-4) (mean differences 2.62, 95% CI 1.96-3.28, P < .00001) in the treatment of UC, and reduce interferon-γ (mean differences -5.38, 95% CI -6.81 to -3.94, P < .00001). The effective rates of colonoscopy (RR 0.94, 95% CI 0.84-1.05, P = .25), pathological examination (RR 1.04, 95% CI 0.90-1.20, P = .60) and rate of adverse reaction (RR 0.55, 95% CI 0.25-1.21, P = .14) were the same. Trial sequential analysis indicated that the benefits of effective rates of clinical comprehensive and syndrome, IL-4, and interferon-γ were conclusive. Harbord regression showed no publication bias (P = .98). The evaluation of evidence quality suggested that the evidence quality of effective rates of clinical comprehensive and syndrome was moderate and the evidence quality of other indicators was low or very low. CONCLUSION: Acupoint application is a safe and effective method for the treatment of UC, and has the prospect of clinical application.

摘要:
Ischemic stroke is currently one of the biggest threats to global health due to its high mortality and dis-ability rate. Thrombolysis with intravenous alteplase remains a primary therapy for acute ischemic stroke. Nevertheless, haemorrhage may be triggered to cause secondary victimization to the patients. On the other hand, the compensatory cerebral collaterals developing in response to ischemia stroke help preserve the penumbral area where the neurons are considered to be salvageable. In this context, precisely evaluating the collateral circulation and predicting the thrombolytic risk of stroke are extremely important not only for treatment decision making but also for a good prognosis. Aiming at identifying the ischemic penumbra and precisely predicting the possible thrombolytic haemorrhage risk prior to thrombolytic therapy, we herein report a dual-targeted magnetic resonance imaging (MRI) nanoprobe based on magnetic iron oxide na-noparticles for visualizing both cerebral collateral circulation and ischemic inflammation. Focal cerebral ischemia rat models were adopted for imaging studies on 7.0 Tesla MRI with different sequences. The imaging results revealed that the nanoprobe could target the newly formed collateral vessels and in-flammatory lesions in the cerebral ischemic region, which enabled the visualization of the potential hae-morrhage sites of thrombolytic therapy apart from the ischemic penumbra. The current studies therefore offer for the first time a noninvasive approach for precisely predicting potential reperfusion haemorrhage through MRI.(c) 2022 Elsevier Ltd. All rights reserved.
