Respir Res 2024; 25:70. [PMID: 38317182 PMCID: PMC10840147 DOI: 10.1186/s12931-024-02713-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Accepted: 01/28/2024] [Indexed: 02/07/2024] Open
Abstract
BACKGROUND Currently, there are no reliable clinical tools that allow non-invasive therapeutic support for patients with pulmonary arterial hypertension. This study aims to propose a low-frequency ultrasound device for pulmonary hypertension therapy and to demonstrate its potential. METHODS A novel low-frequency ultrasound transducer has been developed. Due to its structural properties, it is excited by higher vibrational modes, which generate a signal capable of deeply penetrating biological tissues. A methodology for the artificial induction of pulmonary hypertension in sheep and for the assessment of lung physiological parameters such as blood oxygen concentration, pulse rate, and pulmonary blood pressure has been proposed. RESULTS The results showed that exposure of the lungs to low-frequency ultrasound changed physiological parameters such as blood oxygen concentration, pulse rate and blood pressure. These parameters are most closely related to indicators of pulmonary hypertension (PH). The ultrasound exposure increased blood oxygen concentration over a 7-min period, while pulse rate and pulmonary blood pressure decreased over the same period. In anaesthetised sheep exposed to low-frequency ultrasound, a 10% increase in SpO2, a 10% decrease in pulse rate and an approximate 13% decrease in blood pressure were observed within 7 min. CONCLUSIONS The research findings demonstrate the therapeutic efficiency of low-frequency ultrasound on hypertensive lungs, while also revealing insights into the physiological aspects of gas exchange within the pulmonary system.

Abstract
Understanding the complex interplay of pro-inflammatory and anti-inflammatory cytokines is crucial in the field of wound healing, as it holds the key to developing effective therapeutics. In the initial stages of wound healing, pro-inflammatory cytokines like IL-1β, IL-6, TNF-α, and various chemokines play vital roles in recruiting cells for debris clearance and the recruitment of growth factors. Careful regulation and timely resolution of this early inflammation are essential for optimal wound repair. As the healing process progresses, anti-inflammatory proteins such as IL-10 and IL-4 become instrumental in facilitating the transition to later stages where pro-inflammatory cytokines promote angiogenesis and wound remodeling. This Perspective underscores the complexity of inflammatory cytokines in wound healing research and emphasizes the need for comprehensive and unbiased methodologies in their evaluation. For robust and reliable results in wound-healing research, a more holistic approach is necessary-one that considers the roles, interactions, and timing of biological molecules, alongside careful sampling and evaluation strategies.

Front Endocrinol (Lausanne) 2022; 13:1046896. [PMID: 36506057 PMCID: PMC9732241 DOI: 10.3389/fendo.2022.1046896] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Accepted: 11/09/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Diabetic foot ulcer (DFU) is one of the serious complications of diabetes, which has high disability rate and mortality. Low-intensity ultrasound combined with microbubbles in blood circulation can enhance the blood perfusion effect of local soft tissue, which has the potential to promote the healing of diabetic ulcer. Here, we report how this method was used to help the healing of two patients with chronic refractory DFUs. CASE PRESENTATION In case 1, a 56-year-old man with 3-years history of type 2 diabetes had a 3.0×2.0 cm ulcer which infected with staphylococcus aureus on his right calf for more than half a month. In case 2, a 70-year-old man with 10-years history of type 2 diabetes presented with an 8-month right heel ulcer that developed to 7.5×4.6 cm. And he also had hyperlipidemia, hypertension, and renal impairment. Both patients were enrolled in our study to receive treatment of low-intensity diagnostic ultrasound (LIDUS) combined with microbubbles. They were discharged after a 20-minute daily standard treatment for 7 consecutive days. The ulcers in both cases completely healed in 60 days and 150 days, respectively, and haven't recurred for more than one year of follow-up. CONCLUSION It is feasible, safe, and effective to use commercial LIDUS combined with commercial microbubbles in the treatment of diabetic lower extremity ulcers. This study may provide an innovative and non-invasive method for the treatment of DFUs.

Mechanisms of Dangua Recipe in Improving Glycolipid Metabolic Disorders Based on Transcriptomics. Chin J Integr Med 2021; 28:130-137. [PMID: 34755288 DOI: 10.1007/s11655-021-3337-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/13/2020] [Indexed: 10/19/2022]
Abstract
OBJECTIVE To explore the mechanisms of Dangua Recipe (DGR) in improving glycolipid metabolism based on transcriptomics. METHODS Sprague-Dawley rats with normal glucose level were divided into 3 groups according to a random number table, including a conventional diet group (Group A), a DGR group (Group B, high-calorie diet + 20.5 g DGR), and a high-calorie fodder model group (Group C). After 12 weeks of intervention, the liver tissue of rats was taken. Gene sequence and transcriptional analysis were performed to identify the key genes related to glycolipid metabolism reflecting DGR efficacy, and then gene or protein validation of liver tissue were performed. Nicotinamide phosphoribosyl transferase (Nampt) and phosphoenolpyruvate carboxykinase (PEPCK) proteins in liver tissues were detected by enzyme linked immunosorbent assay, fatty acid synthase (FASN) protein was detected by Western blot, and fatty acid binding protein 5 (FABP5)-mRNA was detected by quantitative real-time polymerase chain reaction. Furthermore, the functional verification was performed on the diabetic model rats by Nampt blocker (GEN-617) injected in vivo. Hemoglobin A1c (HbA1c), plasma total cholesterol and triglycerides were detected. RESULTS Totally, 257 differential-dominant genes of Group A vs. Group C and 392 differential-dominant genes of Group B vs. Group C were found. Moreover, 11 Gene Ontology molecular function terms and 7 Kyoto Encyclopedia of Genes and Genomes enrichment pathways owned by both Group A vs. Group C and Group C vs. Group B were confirmed. The liver tissue target validation showed that Nampt, FASN, PEPCK protein and FABP5-mRNA had the same changes consistent with transcriptome. The in vivo functional tests showed that GEN-617 increased body weight, HbA1c, triglyceride and total cholesterol levels in the diabetic rats (P<;0.05 or P<;0.01); while all the above-mentioned levels (except triglyceride) were decreased significantly by GEN-617 combined with DGR intervention (P<;0.05 or P<;0.01). CONCLUSION Nampt activation was one of the mechanisms about DGR regulating glycolipid metabolism.

Abstract
Objective This study aimed to examine the changes and significance of matrix metalloproteinase 9 (MMP9), MMP2, tissue inhibitor of metalloproteinase 1 (TIMP1), and TIMP2 in rats with lipopolysaccharide (LPS)-induced acute lung injury (ALI). Methods Wistar rats were randomly divided into a control group (injected with saline) and an ALI group (injected with LPS), then subdivided into four time points (2, 6, 12, and 24 hours). Serum tumor necrosis factor alpha and interleukin-6 levels were detected by ELISA to investigate the inflammatory reaction after LPS injection. The degree of ALI was determined by hematoxylin–eosin staining of lung tissue, the lung wet/dry weight ratio, and pulmonary permeability index. Changes in lung MMP and TIMP protein and mRNA levels were detected by western blotting and quantitative real-time polymerase chain reaction. Results Changes in the ratios of MMP9/TIMP1 and MMP2/TIMP2 were consistent with and strongly positively associated with the lung wet/dry weight ratio, the pulmonary permeability index, and serum tumor necrosis factor alpha and interleukin-6 levels in the ALI group. Conclusion ALI induced by LPS may be related to upregulation of MMP9/TIMP1 and MMP2/TIMP2 ratios.

Salvia miltiorrhiza Injection Alleviates LPS-Induced Acute Lung Injury by Adjusting the Balance of MMPs/TIMPs Ratio. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:9617081. [PMID: 32765635 PMCID: PMC7387992 DOI: 10.1155/2020/9617081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 06/10/2020] [Accepted: 07/01/2020] [Indexed: 11/26/2022]
Abstract
Salvia miltiorrhiza injection (SMI) is a classical traditional Chinese medicine, which plays an active role in the treatment of many diseases such as promoting blood circulation, removing blood stasis, reducing inflammatory reaction, and improving acute lung injury (ALI). Previous studies have shown that matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) are involved in the pathophysiological process of ALI. However, the relationship between SMI and MMPs/TIMPs remains unclear. In this study, Wistar rats were randomly divided into control group (NC), Salvia miltiorrhiza group (SM), lipopolysaccharide group (LPS), and Salvia miltiorrhiza treatment group (Tsm). The four groups were subdivided into four time points (2, 6, 12, and 24 hours), and specimens were collected after animal sacrifice at each time point. Serum TNF-α and IL-6 levels were detected by ELISA. The degree of lung injury was determined by lung tissue hematoxylin-eosin staining, lung wet/dry weight (W/D) ratio, and lung permeability index. The changes in lung MMPs/TIMPs protein and mRNA were detected by Western blot and real-time quantitative PCR. The results showed that rats injected with LPS experience acute lung injury, and the ratio of MMPs/TIMPs in lung tissues increased gradually with time. In the Tsm group, the ratio of MMPs/TIMPs decreased gradually, and likewise, the balance was gradually restored, while indicators related to lung injury were gradually declined. These data suggest that SMI alleviates LPS-induced acute lung injury; this protective effect may be related to regulation of the balance of MMPs/TIMPs ratio.
