The erythroid-specific enzyme δ-aminolevulinate synthase 2 (ALAS2) is a key rate-limiting factor in heme biosynthesis,with its expression increasing in late-stage erythropoiesis to meet heme demands (Sadlon et al., 1999). Zebrafish (Danio rerio) is a well-established model for studying erythropoiesis due to its genetic tractability and optical transparency (Zhang and Hamza, 2019;Zhang et al., 2021). The Tol2-mediated Gal4-UAS system has been widely applied for gene and enhancer trapping in zebrafish (Asakawa and Kawakami, 2009). However, reliable Gal4 enhancer-trap lines for erythropoiesis remain limited. Here, we report a transgenic zebrafish line with erythroid-specific Gal4FF expression under the control of the endogenous alas2 promoter, offering a more precise erythroblast labeling than the gata1a reporter line. This model provides a valuable tool for erythroid-specific investigations of blood flow dynamics and gene function.展开更多

Methods: Sixty patients with diagnosis of CHD-UAP confirmed and differentiated to be Qi-deficiency and blood stasis by TCM were randomly divided into two groups and treated, on the basis of Western drug-therapy, with Tongxinluo capsule (通心络胶囊, TXL) and Huoxue Tongmai capsule (活血通脉胶囊, HXTM) respectively by way of oral taking three times a day, 3 capsules every time, with 1 month as one therapeutic course. The number of CEC in patients' blood circulation was counted before and after treatment. Besides, the number of CEC in 30 healthy persons was also counted for control. Results: The number of CEC in CHD-UAP patients was significantly higher than that in the healthy persons (P<0.01). After the patients were treated with CH, either TXL or HXTM, it significantly decreased (P<0.01)with insignificant difference between the two treated groups. Conclusion: CEC in CHD-UAP patients is severely damaged and endothelial function in disorder, Chinese herbs have protective effect on patients' CEC.展开更多

In this study, the essence of Qi is explored in the view of circulation of blood and interstitial fluid. METHODS: Because the concept of Qi is complicated, Qi deficiency syndrome (QDS) is chosen to probe the relationship between of Qi deficiency and Qi-blood circulation (QBC). We analyze Qi-blood theory in terms of WM, set up a hemodynamic model to describe QBC, and review clinical research on QDS in the view of blood-interstitial fluid circulation. RESULTS: QDS is caused by imbalances of substance exchanges between blood and interstitial fluid, leading to an increase in the interstitial liquid volume or a decrease in nutrients and retention ofmetabolic wastes in interstitial fluid. CONCLUSION: This study describes the essence of Qi, providing support for further research on theories of Qiand Qi-blood circulation inTCM.展开更多

文摘Erythroid cells, the predominant circulating blood cells, are essential for oxygen and carbon dioxide transport (Obeagu, 2024).Their production, erythropoiesis, involves the coordinated synthesis of globin chains and heme molecules to assemble hemoglobin(Zhang et al., 2021). The erythroid-specific enzyme δ-aminolevulinate synthase 2 (ALAS2) is a key rate-limiting factor in heme biosynthesis,with its expression increasing in late-stage erythropoiesis to meet heme demands (Sadlon et al., 1999). Zebrafish (Danio rerio) is a well-established model for studying erythropoiesis due to its genetic tractability and optical transparency (Zhang and Hamza, 2019;Zhang et al., 2021). The Tol2-mediated Gal4-UAS system has been widely applied for gene and enhancer trapping in zebrafish (Asakawa and Kawakami, 2009). However, reliable Gal4 enhancer-trap lines for erythropoiesis remain limited. Here, we report a transgenic zebrafish line with erythroid-specific Gal4FF expression under the control of the endogenous alas2 promoter, offering a more precise erythroblast labeling than the gata1a reporter line.

文摘Intracerebral hemorrhage(ICH) is a significant and growing threat to human health,with increasing incidence.Promoting blood circulation and removing blood stasis therapy(PBCRBS),a Traditional Chinese Medicine therapy,can be an adjuvant therapy to benefit patients with ICH by improving clinical efficacy.However,in theory,using PBCRBS to treat ICH carries the risk of hematoma enlargement and rebleeding,which has led to controversy over its application in ICH treatment.To demonstrate the effectiveness and safety of PBCRBS in treating ICH,this review first analyzes the pathological and physiological basis of ICH and secondly,the cascade of response after ICH and the involvement of cytokines and signaling pathways in this process.Finally,experimental and clinical studies on the treatment of ICH with PBCRBS over the past decade were retrieved from the Pub Med and China National Knowledge Infrastructure databases,and the content of these studies was used to summarize commonly used herbs with PBCRBS effects and their mechanisms of action.Through analysis,hypertension has been identified as the most common cause of ICH.Heme,interleukin,reactive oxygen species,coagulation promoting particles and other induced mass effects,inflammation,oxidative stress,and coagulation cascade reactions lead to brain damage following ICH.This review includes 56 experimental studies and 83 clinical studies summarizing 28 commonly used herbs,demonstrating the positive impact of PBCRBS as an adjuvant therapy for ICH.In summary,PBCRBS appears effective and safe for treating ICH.

文摘Short-chain fatty acids,metabolites produced by the fermentation of dietary fiber by gut microbiota,have garnered significant attention due to their correlation with neurodegenerative diseases,particularly Parkinson’s disease.In this review,we summarize the changes in short-chain fatty acid levels and the abundance of short-chain fatty acid-producing bacteria in various samples from patients with Parkinson’s disease,highlighting the critical role of gut homeostasis imbalance in the pathogenesis and progression of the disease.Focusing on the nervous system,we discuss the molecular mechanisms by which short-chain fatty acids influence the homeostasis of both the enteric nervous system and the central nervous system.We identify key processes,including the activation of G protein-coupled receptors and the inhibition of histone deacetylases by short-chain fatty acids.Importantly,structural or functional disruptions in the enteric nervous system mediated by these fatty acids may lead to abnormalα-synuclein expression and gastrointestinal dysmotility,which could serve as an initiating event in Parkinson’s disease.Furthermore,we propose that short-chain fatty acids help establish communication between the enteric nervous system and the central nervous system via the vagal nerve,immune circulation,and endocrine signaling.This communication may shed light on their potential role in the transmission ofα-synuclein from the gut to the brain.Finally,we elucidate novel treatment strategies for Parkinson’s disease that target short-chain fatty acids and examine the challenges associated with translating short-chain fatty acid-based therapies into clinical practice.In conclusion,this review emphasizes the pivotal role of short-chain fatty acids in regulating gut-brain axis integrity and their significance in the pathogenesis of Parkinson’s disease from the perspective of the nervous system.Moreover,it highlights the potential value of short-chain fatty acids in early intervention for Parkinson’s disease.Future research into the molecular mechanisms of short-chain fatty acids and their synergistic interactions with other gut metabolites is likely to advance the clinical translation of innovative short-chain fatty acid-based therapies for Parkinson’s disease.

文摘OBJECTIVE: Based on comparison between fundamental theories of Traditional Chinese Medicine (TCM) and Western Medicine (WM) and modern scientific research on meridians, we find that "Qi" in TCM is closely related to tissue fluid. In this study, the essence of Qi is explored in the view of circulation of blood and interstitial fluid. METHODS: Because the concept of Qi is complicated, Qi deficiency syndrome (QDS) is chosen to probe the relationship between of Qi deficiency and Qi-blood circulation (QBC). We analyze Qi-blood theory in terms of WM, set up a hemodynamic model to describe QBC, and review clinical research on QDS in the view of blood-interstitial fluid circulation. RESULTS: QDS is caused by imbalances of substance exchanges between blood and interstitial fluid, leading to an increase in the interstitial liquid volume or a decrease in nutrients and retention ofmetabolic wastes in interstitial fluid. CONCLUSION: This study describes the essence of Qi, providing support for further research on theories of Qiand Qi-blood circulation inTCM.

文摘OBJECTIVE:To explore the blood circulation activating effect and mechanism of Sanqi(Radix Notoginseng)in vivo,using a venous thromboembolism(VTE)rat model.METHODS:We established the VTE rat model,and then intervened with low molecular weight hepa-rin(LMWH),as well as low,medium and high doses of Sanqi(Radix Notoginseng),to observe the blood circulation activating effect of Sanqi(Radix Notoginseng)on VTE rats.RESULTS:After the treatment with high concentrations of Sanqi(Radix Notoginseng),the pulmonary thromboembolism was alleviated,and the lower limb thrombosis was markedly improved.Moreover,the expression quantities of plasma activated partial thromboplastin time,prothrombin time and D-dimer,as well as endothelin,von Willebrand factor,and plasminogen activator inhibitor-1 in thrombosis segment tissues were markedly down-regulated;while those of nitric oxide and tissue-type plasminogen activator were up-regulated.After low and medium concentration Sanqi(Radix Notoginseng)treatment,no obvious improvement was observed in each index.Moreover,the high concentration Sanqi(Radix Notoginseng)showed comparable efficacy to the positive drug LMWH.CONCLUSION:This data suggests that high concentration of Sanqi(Radix Notoginseng)is effective in preventing and treating VTE.
文摘Objective: To explore the clinical efficacy of the principle of activating blood circulation to break stasis (ABCBS) and its influence on platelet membranous protein particle (GMP-140) and D 2 dimer (D-dimer) before and after treatment. Methods: Eighty-eight patients with blood stasis syndrome (BSS) of acute cerebral infarction (ACI) were randomly divided into two groups, both of which were treated with conventional treatment, i.e. with western medicine (WM), with Salvia injection added through intravenously dripping.One of the two groups was used as the control and the other group as the treated group who had ABCBS herbs orally taken in addition. The duration of treatment course for both groups was 3 weeks. Results: There were changes in both groups over clinical symptoms, nerve function deficit scoring and GMP-140, D-dimer, but the treated group showed significantly better than that of the control group, ( P <0.05). Conclusion: ABCBS principle could serve as an important auxiliary treating method for BSS of ACI, as it can effectively alter the blood of ACI patients which was viscous, condense, coagulant and aggregating.

文摘To reveal the resonance suppression mechanism of the blood circulation in dragonfly wings,a numerical modeling method of dragonfly wings based on Voronoi diagrams is proposed,and the changes in mass,aerodynamic damping,and natural frequencies caused by blood circulation in veins are investigated.The equivalent mass of blood,boundary conditions,and aerodynamic damping are calculated theoretically.Modal analysis and harmonic response analysis of wing models with different blood circulation paths are performed using the finite-element method(FEM).The vibration reduction ratioδis introduced to compare the damping efficiency of different mass regions.Finally,a natural frequency testing device is constructed to measure the natural frequencies of dragonfly wings.The results indicate that the shape,mass,and natural frequencies of the dragonfly wing model constructed by numerical method agree well with reality.The mass distribution on the wing can be altered by blood circulation,thereby adjusting the natural frequencies and achieving resonance suppression.The highestδof 1.013 is observed in the C region when blood circulates solely in secondary veins,but it is still lower than theδof 1.017 when blood circulates in complete veins.The aerodynamic damping ratio(1.19–1.79%)should not be neglected in the vibration analysis of the beating wing.
