Abstract
ABSTRACT Chronic wounds, including those caused by venous and arterial insufficiency, diabetic complications, and pressure-induced ulcers, pose significant treatment challenges. Negative pressure wound therapy has been increasingly used for managing these wounds. This treatment aims to promote wound healing, prepare the wound bed for further surgical intervention, minimize the risk of infection, and potentially shorten the time to wound healing. Considering variances in techniques applied in different regions globally, there is an emerging need to comprehensively evaluate the effectiveness of negative pressure wound therapy on chronic wounds. Unfortunately, detailed descriptions of the techniques applied to achieve negative pressure are often lacking in existing literature abstracts, posing challenges for direct comparisons. This review aims to analyze the application of negative pressure wound therapy in the treatment of chronic wounds, summarize its advantages and disadvantages, and further explore the potential value and future research direction of negative pressure wound therapy in the repair of chronic wounds.

Abstract
Background Chronic infectious wounds seriously affect patients' quality of life. Aim To assess the effect of whole course seamless nursing mode on patients with chronic infectious wounds. Methodology One hundred patients treated between January 2019 and December 2020 were randomly divided into control and observation groups (n=50) that were given routine nursing and whole course seamless nursing, respectively. Their pain score, comfort score, wound healing time, wound healing effect, psychological state scores, sleep indices, quality-of-life scores and degree of satisfaction with nursing were compared. Results Observation group had lower pain score and higher comfort score than those of control group after nursing (P<0.05). Compared with control group, observation group had shorter wound healing time and higher grade-A wound healing rate (P<0.05). The SDS and SAS scores of observation group were lower than those of control group (P<0.05). Observation group also had significantly shorter sleep latency, longer actual sleep time, lower PSQI score, as well as higher quality-of-life score and overall satisfaction rate than those of control group (P<0.05). Conclusion For patients with chronic infectious wounds, whole course seamless nursing effectively relieves wound pain, facilitates wound healing, improves comfort, psychological state and sleep status, and makes them more satisfied.

A meta-analysis on the efficacy of vacuum sealing drainage combined with autologous platelet-rich plasma in the treatment of Grade 2 and Grade 3 diabetic foot ulcers. Int Wound J 2023; 20:1033-1041. [PMID: 36111514 PMCID: PMC10031232 DOI: 10.1111/iwj.13956] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 08/25/2022] [Accepted: 08/26/2022] [Indexed: 11/29/2022] Open
Abstract
This meta-analysis aims to systemically evaluate the efficacy of vacuum sealing drainage (VSD) combined with autologous platelet-rich plasma (PRP) in the treatment of diabetic foot ulcers (DFU). The China HowNet, China Biomedical Literature, VIP periodical resource integration service platform, Wanfang, Embase, Cochrane Central, and PubMed databases were retrieved using the computer. The retrieval period was up to July 2021. Randomised controlled trials on VSD combined with PRP in the treatment of DFU were collected. Those trials that met the inclusion criteria were included for meta-analysis using RevMan 5.3 software. A total of 13 articles were included. In the trial group, 477 patients with DFU were treated with VSD combined with PRP, while in the control group, 482 patients with DFU were treated with conventional dressings and/or VSD. The meta-analysis showed that, compared with the control group, VSD combined with PRP has significant advantages in shortening healing time (standardised mean difference [SMD] = -0.87, 95% confidence interval [CI]: -1.07 to -0.67, P < .00001), improving ulcer healing rates (odds ratio = 4.01, 95% CI: 2.95 ~ 5.46, P < .00001), and reducing hospital stays (mean difference = -15.29, 95% CI: -16.05 to -14.54, P < .00001), but the differences in dressing change times (SMD = -1.27, 95% CI: -2.71 to 0.17, P = .08) and hospitalisation expenses (SMD = -0.16, 95% CI: -13.40 to 13.07, P = .98) were not statistically significant. VSD combined with autologous PRP has good curative efficacy in the treatment of DFU and is a better treatment option. However, this treatment is limited in patients with platelet dysfunction, thrombocytopenia, leukaemia, and poor general condition.

Low-intensity pulsed ultrasound prevents angiotensin II-induced aortic smooth muscle cell phenotypic switch via hampering miR-17-5p and enhancing PPAR-γ. Eur J Pharmacol 2021; 911:174509. [PMID: 34547245 DOI: 10.1016/j.ejphar.2021.174509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 09/14/2021] [Accepted: 09/15/2021] [Indexed: 10/20/2022]
Abstract
Vascular events can trigger a pathological phenotypic switch in vascular smooth muscle cells (VSMCs), decreasing and disrupting the plasticity and diversity of vascular networks. The development of novel therapeutic approaches is necessary to prevent these changes. We aimed to investigate the effects and associated mechanisms of low-intensity pulsed ultrasound (LIPUS) irradiation on the angiotensin II (AngII)-induced phenotypic switch in VSMCs. In vivo, AngII was infused subcutaneously for 4 weeks to stimulate vascular remodeling in mice, and LIPUS irradiation was applied for 20 min every 2 days for 4 weeks. In vitro, cultured rat aortic VSMCs (RAVSMCs) were pretreated once with LIPUS irradiation for 20 min before 48-h AngII stimulation. Our results showed that LIPUS irradiation prevents AngII-induced vascular remodeling of the whole wall artery without discriminating between adventitia and media in vivo and RAVSMC phenotypic switching in vitro. LIPUS irradiation downregulated miR-17-5p expression and upregulated peroxisome proliferator-activated receptor gamma (PPAR-γ) expression. The PPAR-γ activator rosiglitazone could mimic the favorable effects of LIPUS irradiation on AngII-treated RAVSMCs. In contrast, GW9662 could impede the LIPUS-mediated downregulation of RAVSMC proliferation and inflammation under AngII stimulation conditions in vivo and in vitro. Also, the miR-17-5p agomir has the same effects as GW9662 in vitro. Besides, the inhibitory effects of GW9662 against the anti-remodeling effects of LIPUS irradiation in AngII-induced RAVSMCs could be blocked by pretreatment with the miR-17-5p antagomir. Overall, LIPUS irradiation prevents AngII-induced RAVSMCs phenotypic switching through hampering miR-17-5p and enhancing PPAR-γ, suggesting a new approach for the treatment of vascular disorders.

Abstract
OBJECTIVE To investigate the effect of vacuum sealing drainage (VSD) after early woundabrasion (WA) in diabetic patients with deep second degree burn (DSDB). METHODS This prospective study selected 89 diabetic patients with DSDB treated in our hospital. Using the random number table method, the patients were divided into the control group (44 cases with conventional treatment after early WA) and observation group (45 cases with VSD treatment after WA). Wound healing, fungal infection rate, serum levels of inflammatory factors and vascular endothelial growth factor (VEGF), and adverse reactions in both groups were compared. RESULTS After 2 weeks of treatment, the total effective rate of observation group was higher than that of control group, and the incidence of adverse reactions showed an opposite trend (both P<0.05). Compared with the control group, the wound healing time was shortened, the wound healing rate was increased, and the fungal infection rate was decreased in the observation group (all P<0.05). Compared with before treatment, serum TNF-α levels in both groups were decreased, while serum levels of IL-10, IL-4 and VEGF were increased after treatment, and the changes in the observation group were more obvious (all P<0.05). CONCLUSIONS In diabetic patients with DSDB, VSD after early WA can effectively reduce the incidence of fungal infection, reduce inflammation, improve VEGF level, and facilitate wound healing.

Abstract
BACKGROUND MiR-17 is a small noncoding RNA that plays an important role in the development of tumorgenesis, which recently has emerged to be involved in regulation of inflammatory responses and angiogenesis. However, the effect and underlying mechanism of miR-17 on vascular smooth muscle cell (VSMC) phenotypic modulation have not been investigated. METHODS AND RESULTS In the current study, we observed that miR-17 expression tested by real-time polymerase chain reaction (RT-PCR) was downregulated in VSMCs administrated with platelet-derived growth factor-BB stimulation and carotid arteries subjected to wire injury, which were accompanied with decreased VSMC differentiation markers. Loss-of-function strategy demonstrated that miR-17 knockdown promoted VSMC phenotypic modulation characterized as decreased VSMC differentiation marker genes, increased proliferated and migrated capability of VSMC examined by RT-PCR and western blot analysis. Mechanistically, the bioinformatics analysis and luciferase assay demonstrated that miR-17 directly targeted Interferon Regulator Factor 9 (IRF9) and the upregulated IRF9 expression was responsible for the promoted effect miR-17 knockdown on VSMC phenotypic modulation. CONCLUSIONS Taken together, our results demonstrated that miR-17 knockdown accelerated VSMC phenotypic modulation partially through directly targeting to IRF9, which suggested that miR-17 may act as a novel therapeutic target for intimal hyperplasia management.

Abstract
Seawater (SW) immersion can increase the damage of skin wounds and produce refractory wounds. However, few studies have been conducted to investigate the mechanisms of SW immersion on skin wounds. In our current study, we investigated the effect of human adipose-derived stem cells (hADSCs) on the repair of SW-treated full-thickness skin wounds and the underlying mechanisms. The results showed that SW immersion could reduce the expression of EGF and suppress the activation of the MEK/ERK signaling pathway. At the same time, the proliferation and migration of skin stem cells were inhibited by SW immersion, resulting in delayed wound healing. However, hADSCs significantly accelerated the healing of SW-immersed skin wounds by promoting cell proliferation and migration through the aforementioned mechanisms. Our results indicate a role for hADSCs in the repair of seawater-immersed skin wounds and suggest a potential novel treatment strategy for seawater-immersed wound healing.

Efficacy of combined treatment with vacuum sealing drainage and recombinant human epidermal growth factor for refractory wounds in the extremities and its effect on serum levels of IL-6, TNF-α and IL-2. Exp Ther Med 2017; 15:288-294. [PMID: 29250151 PMCID: PMC5729703 DOI: 10.3892/etm.2017.5360] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2017] [Accepted: 10/06/2017] [Indexed: 12/27/2022] Open
Abstract
The objective of this study was to investigate the efficacy of combined treatment with vacuum sealing drainage (VSD) and recombinant human epidermal growth factor (rhEGF) for refractory wounds in the extremities, and its effect on serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and IL-2. Ninety-eight patients with refractory wounds in the extremities were recruited and randomly divided into the combined treatment group (underwent VSD and rhEGF treatment) and control group (underwent VSD only) with 49 cases each. Formation of granulation tissue on the wound surface was assessed and scored. The wound healing rate was calculated after 1 week of treatment, and the time of complete healing was recorded. Serum levels of IL-6, IL-2, and TNF-α were measured using enzyme-linked immunosorbent assay. After 1 week of treatment, granulation tissue formation on wound surfaces was significantly improved (p<0.05) compared with that before treatment in both groups. Moreover, granulation tissue formation on wound surfaces was superior in the combined treatment group than in the control group (p<0.05). The wound healing rate was 63.50±4.75% in the combined treatment group and 31.79±3.52% in the control group, and the difference was statistically significant (p<0.05). The time of complete healing was 15.11±2.24 days in the combined treatment group and 19.63±2.76 days in the control group, and the difference was statistically significant (p<0.05). The serum levels of IL-6, IL-2, and TNF-α, in the two groups were significantly lower than those before treatment (p<0.05). Moreover, the levels in the combined treatment group were significantly lower than those in the control group (p<0.05). In conclusion, combined treatment with VSD and rhEGF reduced inflammation and shortened the time of complete healing of refractory wounds in the extremities. Measurement of the levels of related inflammatory factors provided a reference for the prognosis of refractory wounds.
