Surgical site infections (SSIs) post-thoracoscopic radical resection in lung cancer patients pose significant clinical challenges. This study aims to comprehensively identify the independent risk factors that influence the occurrence of SSIs following thoracoscopic radical resection for lung cancer. The study employed a retrospective analysis of 130 patients who underwent thoracoscopic radical resection for lung cancer. Inclusion and exclusion criteria were clearly defined, and ethical approvals were obtained. Patients were monitored for SSIs via clinical and biochemical markers, with data comprehensively gathered from electronic health records. Statistical analysis was rigorously conducted using SPSS v27.0, with methodologies including t-tests, Chi-square tests and logistic regression. The study aimed to identify independent risk factors for SSIs and incorporated a multidimensional assessment approach to provide robust, clinically relevant findings. Univariate analysis revealed surgical duration ≥3 h, non-usage of antibiotics, presence of diabetes and elevated levels of C-reactive protein (CRP) and procalcitonin (PCT) as significant correlates for SSIs. Multivariate analysis substantiated these factors as independent risk variables: surgery duration (odds ratio [OR] = 9.698, p < 0.05), presence of diabetes (OR = 6.89, p < 0.05), elevated CRP (OR = 7.306, p < 0.05) and elevated PCT (OR = 6.838, p < 0.05). Conversely, antibiotic administration served as a protective factor (OR = 0.572, p < 0.05). Surgical duration of 3 h or more, diabetes and elevated levels of CRP and PCT significantly heighten the risk for SSIs after thoracoscopic radical resection in lung cancer patients. Perioperative antibiotic administration acts as a protective factor. Clinicians should implement tailored preventative strategies to mitigate these identified risks.
Psoriasis and chronic ulcers not only significantly impair quality of life but also pose a challenge in dermatological treatment. This study aimed to identify new therapeutic targets and biomarkers for psoriasis and chronic ulcers by comparing their gene expression profiles. The gene expression profiles of psoriatic, wound and chronic ulcer patients, as well as healthy controls, were determined via RNA extraction and next-generation sequencing of biopsies. In order to identify biomarkers, functional enrichment, differential expression analysis and machine learning algorithms were implemented. It is worth mentioning that the genes IL17A, TNF, KRT16, MMP9, and CD44 exhibited substantial correlations with the pathogenesis of the conditions being studied. As evidenced by their AUC-ROC values approaching 0.90, machine learning models accurately identified these biomarkers. The differential gene expression was consequently validated via qRT-PCR, which highlighted the increased expression of matrix remodelling enzymes and inflammatory cytokines. Additionally, genes essential for maintaining epidermis integrity and facilitating wound healing exhibited downregulation. These insights into the molecular mechanisms of psoriasis and chronic ulcers pave the way for the development of targeted therapies, offering hope for improved treatment strategies.
This meta-analysis evaluated the role of evidence-based nursing interventions in preventing pressure ulcers in patients with stroke. Computer systems were used to retrieve randomised controlled trials (RCTs) on evidence-based nursing interventions for patients with stroke and comorbid pressure ulcers from PubMed, EMBASE, Scopus, Cochrane Library, China National Knowledge Infrastructure, Chinese Biomedical Literature Database and Wanfang Data from database inception until April 2023. Two researchers independently screened the literature, extracted the data and evaluated the quality of the included studies according to the inclusion and exclusion criteria. RevMan 5.4 software was used for the meta-analysis. A total of 23 articles with results on 2035 patients were included, with 1015 patients in the evidence-based nursing group and 1020 patients in the routine nursing group. The meta-analysis results showed that evidence-based nursing interventions significantly reduced the incidence of pressure ulcers in patients with stroke (5.22% vs. 22.84%, odds ratio [OR]: 0.18, 95% confidence interval [CI]: 0.13–0.24, p < 0.001), delayed the onset of pressure ulcers (standardised mean difference [SMD]: 3.41, 95% CI: 1.40–5.42, p < 0.001) and improved patient quality of life (SMD: 2.95, 95% CI: 2.35–3.56, p < 0.001). Evidence-based nursing interventions are effective at preventing pressure ulcers in patients with stroke, delaying the onset of pressure ulcers and improving their quality of life. Evidence-based nursing should be promoted for patients with stroke. However, owing to differences in sample size between studies and the methodological inadequacies of some studies, these results should be verified by large, high-quality RCTs.
Diabetic foot ulcer often leads to amputation, and both nutritional status and immune function have been associated with this process. We aimed to investigate the risk factors of diabetic ulcer-related amputation including the Controlling Nutritional Status score and neutrophil-to-lymphocyte ratio biomarker. We evaluated data from hospital in patients with diabetic foot ulcer, performing univariate and multivariate analyses to screen for high-risk factors and Kaplan–Meier analysis to correlate high-risk factors with amputation-free survival. Overall, 389 patients underwent 247 amputations over the follow-up period. After correction to relevant variables, we identified five independent risk factors for diabetic ulcer-related amputation: ulcer severity, ulcer site, peripheral arterial disease, neutrophil-to-lymphocyte ratio and nutritional status. Amputation-free survival was lower for the moderate-to-severe versus mild cases, for the plantar forefoot versus hindfoot location, for the concomitant peripheral artery disease versus without and in the high versus low neutrophil-to-lymphocyte ratio (all p < 0.01). The results showed that ulcer severity (p < 0.01), ulcer site (p < 0.01), peripheral artery disease (p < 0.01), neutrophil-to-lymphocyte ratio (p < 0.01) and Controlling Nutritional Status score (p < 0.05) were independent risk factors for amputation in diabetic foot ulcer patients and have predictive values for diabetic foot ulcer progression to amputation.
Amputations related to diabetic foot ulcers (DFU) are associated with high morbidity and mortality rates. Glycaemic control and close follow-up protocols are essential to prevent such ulcers. Coronavirus disease (COVID) related restrictions and regulations might have a negative impact on patients who are with DFU or candidates for DFU. We retrospectively analysed 126 cases that had DFU underwent amputation surgery. Comparative analyses were done between cases that were admitted before COVID restrictions (Group A) and cases admitted after COVID restrictions (Group B). Two groups were homogenic demographically. There was no significant difference between groups in terms of mortality (p = 0.239) and amputation rates (p = 0.461). The number of emergent cases in the pandemic period doubled the number in pre-pandemic period even though this finding was not statistically significant (p = 0.112). Fastly adapted consulting practice and follow-up protocols to compensate for the problems created by COVID-related regulations seem to be effective in terms of mortality and amputation rates.
This meta-analysis aimed to evaluate the impact of autologous platelet concentrates (APCs) on wound area reduction based on randomized controlled trials (RCTs). A comprehensive search was conducted in PubMed, Embase, China National Knowledge Infrastructure (CNKI), Web of Science, and the Cochrane Library to identify relevant literature. The primary outcome measure was the percentage of wound area reduction. Secondary outcome measures included wound healing time and the incidence of infection. A total of 14 studies were included in the meta-analysis. The results showed that the percentage of wound area reduction was significantly greater in the APCs group compared to conventional treatments (standardized mean difference [SMD] 1.98, 95% confidence interval [CI]: 1.27–2.68, p < 0.001). Subgroup analysis revealed that the percentage of wound area reduction varied based on wound location, follow-up duration, and type of APCs used. The healing time and incidence of infection presented no significant difference between the two groups. The findings suggest that APCs can effectively reduce wound areas when compared to conventional treatments, without increasing the risk of infection. In addition, the effectiveness of APCs in wound area reduction may vary depending on factors such as wound location, type of APCs used, and follow-up duration.
Among the assortment of available dressings aimed at promoting wound healing, moist dressings have gained significant popularity because of their ability to create an optimal environment for wound recovery. This meta-analysis seeks to compare the effects of moist dressing versus gauze dressing on wound healing time. A comprehensive literature search was conducted, encompassing publications up until April 1, 2023, across multiple databases including PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), and Cochrane Library. Stringent criteria were used to determine study inclusion and evaluate methodological quality. Statistical analyses were performed utilizing Stata 17.0. A total of 13 articles, encompassing 866 participants, were included in the analysis. The findings indicate that moist dressing surpasses gauze dressing in terms of wound healing time (standard mean difference [SMD] −2.50, 95% confidence interval [CI] −3.35 to −1.66, p < 0.01; I 2 = 97.24%), wound site infection rate (odds ratio [OR] 0.30, 95% CI 0.17 to 0.54, p < 0.01; I 2 = 39.91%), dressing change times (SMD −3.65, 95% CI −5.34 to −1.97, p < 0.01; I 2 = 96.48%), and cost (SMD −2.66, 95% CI −4.24 to −1.09, p < 0.01; I 2 = 94.90%). Subgroup analyses revealed possible variations in wound healing time based on wound types and regions. This study underscores the significant advantages associated with the use of moist dressings, including expedited wound healing, reduced infection rates, decreased frequency of dressing changes, and lower overall treatment costs.
By conducting a meta-analysis of relevant clinical studies on the treatment of advanced gastric cancer (GC) using laparoscopic and open surgeries, we aimed to evaluate the impact of these two surgical approaches on postoperative surgical site infections (SSIs) in patients with advanced GC. We aimed to provide evidence-based support for preventing SSIs in postoperative patients with advanced GC. From database establishment until May 2023, we systematically searched PubMed, Cochrane Library, MEDLINE, Embase, China National Knowledge Infrastructure, and Wanfang Data databases for relevant studies comparing laparoscopic and open surgeries for the treatment of advanced GC. Two researchers independently performed the literature screening and data extraction based on predefined inclusion and exclusion criteria. The meta-analysis was conducted using STATA 17.0. Twenty articles involving 3084 patients met the inclusion criteria, including 1462 patients in the laparoscopic group and 1622 cases in the open surgery group. The meta-analysis results revealed that the incidence of postoperative SSIs was significantly lower in the laparoscopic group than in the open surgery group (odds ratio = 0.341, 95% confidence interval: 0.219–0.532, p < 0.001). The current evidence indicates that laparoscopic radical gastrectomy can significantly reduce the incidence of postoperative site infections in patients with advanced GC.
Despite the fact that machine learning (ML) algorithms to construct predictive models for pressure injury development are widely reported, the performance of the model remains unknown. The goal of the review was to systematically appraise the performance of ML models in predicting pressure injury. PubMed, Embase, Cochrane Library, Web of Science, CINAHL, Grey literature and other databases were systematically searched. Original journal papers were included which met the inclusion criteria. The methodological quality was assessed independently by two reviewers using the Prediction Model Risk of Bias Assessment Tool (PROBAST). Meta-analysis was performed with Metadisc software, with the area under the receiver operating characteristic curve, sensitivity and specificity as effect measures. Chi-squared and I 2 tests were used to assess the heterogeneity. A total of 18 studies were included for the narrative review, and 14 of them were eligible for meta-analysis. The models achieved excellent pooled AUC of 0.94, sensitivity of 0.79 (95% CI [0.78–0.80]) and specificity of 0.87 (95% CI [0.88–0.87]). Meta-regressions did not provide evidence that model performance varied by data or model types. The present findings indicate that ML models show an outstanding performance in predicting pressure injury. However, good-quality studies should be conducted to verify our results and confirm the clinical value of ML in pressure injury development.
A novel autologous heterogeneous skin construct (AHSC) was previously shown to be effective versus standard of care (SOC) treatment in facilitating complete wound healing of Wagner 1 diabetic foot ulcers in an interim analysis of 50 patients previously published. We now report the final analysis of 100 patients (50 per group), which further supports the interim analysis findings. Forty-five subjects in the AHSC treatment group received only one application of the autologous heterogeneous skin construct, and five received two applications. For the primary endpoint at 12 weeks, there were significantly more diabetic wounds closed in the AHSC treatment group (35/50, 70%) than in the SOC control group (17/50, 34%) (p = 0.00032). A significant difference in percentage area reduction between groups was also demonstrated over 8 weeks (p = 0.009). Forty-nine subjects experienced 148 adverse events: 66 occurred in 21 subjects (42%) in the AHSC treatment group versus 82 in 28 SOC control group subjects (56.0%). Eight subjects were withdrawn due to serious adverse events. Autologous heterogeneous skin construct was shown to be an effective adjunctive therapy for healing Wagner 1 diabetic foot ulcers.
A barbed suture has been demonstrated to be effective in shortening the stitching time and improving the aesthetic appearance of the stitches during the entire knee replacement. However, no meta-analyses have been conducted specifically to evaluate the effect of the barbed thread on wound complications relative to the conventional suture. A comprehensive search of the PubMed database, the Embase database, the Cochrane Library and the Web of Science was performed to obtain search data up to June 2023, and only randomised controlled trials were included in this meta-analysis. We used Review Manager 5.3 for data synthesis and analysis. This meta-analysis included eight studies. It was found that the use of barbed sutures did not improve the incidence of the disease, the infection of the wound, the closure of the abscess and the injury. However, because of the limited sample size of the randomised controlled trials for this meta-analysis, the data should be handled with caution. More high-quality, large-sample studies will be required to confirm the results.
Pyoderma gangrenosum (PG) is a non-infectious, neutrophilic dermatosis that was difficult to diagnose in clinical practice. Today, the PARACELSUS score is a validated tool for diagnostics. Based on this score, patients with clearly diagnosed PG were examined with regard to predilection sites. In this retrospective study, the data of patients from the University Hospitals of Essen and Erlangen were analysed in whom the diagnosis of PG could be clearly confirmed using the PARACELSUS score. A total of 170 patients, 49 men (29%) and 121 women (71%) with an average age at first manifestation of 55.5 years, could be included in the analysis. The predilection sites were identified as the lower legs in 80.6% of the patients and the extensor sides in 75.2%. Other localisations of PG were the thighs in 14.1%, mammae and abdomen in 10.0% each, back and gluteal in 7.1% each, feet in 5.9%, arms in 4.7%, genital in 3.5% and head in 2.9%. This retrospective study is the first to identify a collective of PG patients with the highest data quality using the PARACELSUS score. It could be shown that PG can basically occur on the entire integument. However, the predilection sites of PG, which have now been reliably identified for the first time, are the lower legs and in particular the extensor sides.
The meta-analysis aims to evaluate and compare the impact of the combination of stem cells (SCs) and light-based treatments (LBTs) on skin wound (SW) repair. Examinations comparing SCs to LBT with SCs for SW repair was among the meta-analysis from various languages that met the inclusion criteria. Using continuous random-effect models, the results of these investigations were examined, and the mean difference (MD) with 95% confidence intervals was computed (CIs). Seven examinations from 2012 to 2022 were recruited for the current analysis including 106 animals with SWs. Photobiomodulation therapy (PBT) plus SCs had a significantly higher wound closure rate (WCR) (MD, 9.08; 95% CI, 5.55–12.61, p < 0.001) compared to SCs in animals with SWs. However, no significant difference was found between PBT plus SCs and SCs on wound tensile strength (WTS) (MD, 2.01; 95% CI, −0.42 to 4.44, p = 0.10) in animals with SWs. The examined data revealed that PBT plus SCs had a significantly higher WCR, however, no significant difference was found in WTS compared to SCs in animals with SWs. Nevertheless, caution should be exercised while interacting with its values since all the chosen examinations were found with a low sample size and a low number of examinations were found for the comparisons studied for the meta-analysis.
A meta-analysis was performed to assess the effects of different regenerative technologies and materials on wound healing after surgical endodontic therapy and provide a reference for surgical endodontic treatment. We searched for studies on the use of regenerative technologies and materials in surgical endodontic therapy via PubMed, MEDLINE, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang Data from the time of database creation to December 2022. Two researchers independently screened the literature, extracted information based on the inclusion and exclusion criteria, and evaluated the quality of the included studies. A meta-analysis was performed using Review Manager 5.4. The results showed that the use of regenerative technologies and materials significantly reduced wound healing failures (risk ratio [RR]: 0.30, 95% confidence intervals [CI]: 0.22–0.40, p < 0.001). Moreover, autologous platelet concentrations (APCs) (RR: 0.28, 95% CI: 0.15–0.53, p < 0.001) and collagen membrane plus bovine-derived hydroxyapatite (RR: 0.27, 95% CI. 0.12–0.61, p = 0.002) were more effective in improving wound healing failure rates than collagen membrane alone (RR: 0.51, 95% CI: 0.20–1.25, p = 0.140). Our findings showed that APCs, as well as collagen membrane plus bovine-derived hydroxyapatite, significantly improved wound healing after surgical endodontic therapy. In contrast, collagen membrane alone did not significantly improve wound healing outcomes. However, currently available studies vary significantly in sample size and methodologies. Hence, high-quality randomised controlled studies with large sample sizes are necessary to validate our findings.
This meta-analysis is intended to evaluate the effect of both robotic and open-cut operations on postoperative complications of stomach carcinoma. From the earliest date until June 2023, a full and systemic search has been carried out on four main databases with keywords extracted from ‘Robot’, ‘Gastr’ and ‘Opene’. The ROBINS-I instrument has been applied to evaluate the risk of bias in nonrandomized controlled trials. In these 11 trials, a total of 16 095 patients had received surgical treatment for stomach cancer and all 11 trials were nonrandomized, controlled trials. Abdominal abscesses were reported in 5 trials, wound infections in 8 trials, haemorrhage in 7 trials, wound dehiscence in 2 trials and total postoperative complications in 4 trials. Meta-analyses revealed no statistically significantly different rates of postoperative abdominal abscesses among patients who had received robotic operations than in those who had received open surgical procedures (OR, 0.91; 95% CI, 0.25, 3.36; p = 0.89). The incidence of bleeding after surgery was not significantly different from that in both groups (OR, 1.37; 95% CI, 0.69, 2.75; p = 0.37). Similarly, there was no significant difference between the two groups (OR, 0.78; 95% CI, 0.52, 1.18; p = 0.24). No significant difference was found between the two groups (OR, 1. 28; 95% CI, 0.75, 2.21; p = 0.36). No significant difference was found between the two groups of patients who had received the robotic operation and those who had received the surgery after the operation (OR, 1.14; 95% CI, 0.78, 1.66; p = 0.49). Generally speaking, this meta-analysis suggests that the use of robotics does not result in a reduction in certain postsurgical complications, including wound infections and abdominal abscesses. Thus, the use of a microinvasive robot for stomach carcinoma operation might not be better than that performed on the surgical site after the operation. This is a valuable guide for the surgeon to select the operative method.
Pressure ulcers (PUs) are one of the most important care-related ailments, making their prevention a pressing concern for hospital structures. Epidemiology of PU is interesting to adapt human resources and observe the impact of targeted public health measures. Very few data are presented in the French literature. In this context, a dedicated “Pressure ulcer, Wounds and Healing” task force was created in 1996 by a multidisciplinary team of physicians, administrative staff, and paramedics in the CH of Le Mans. Alongside this, an annual prevalence study was performed between 1996 and 2019 in CH of Le Mans, collecting relevant data: the number of patients who presented pressure ulcers, the number of patients who were at risk of developing pressure ulcers, and the severity of these ulcers. This study brings new data about PU epidemiology in France and shows a significant decrease in the prevalence, becoming lower than the national prevalence. Also, a significant time-related regression of the prevalence was observed, the severity level continually decreased whereas the number of geriatric patients grew and patients with PU's risk remained constant. Finally, the number of patients who developed a PU within the hospitalization decreased too. We observed a link between the creation of the task force and the evolution of pressure ulcer epidemiology, thus recommending that the same practices be adopted in other hospitals and fields of application.
In this meta-analysis, we comprehensively evaluated the effect of endoscopic retrograde appendicitis therapy (ERAT) on surgical site infections and other perioperative outcomes in patients with acute appendicitis. Relevant studies on ERAT for acute appendicitis were retrieved from PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure, and Wanfang Data, from database inception to June 2023. Statistical analyses were performed using RevMan 5.4. Heterogeneity among the included studies was analysed, and odds ratios (ORs) or standardised mean differences (SMDs), along with their respective 95% confidence intervals (CIs), were calculated. In total, 24 studies involving 1937 patients were included in the meta-analysis. ERAT reduced the surgical duration (SMD: −1.70, 95% CI: −2.24 to −1.16, p < 0.001) and length of hospital stay (SMD: −2.09, 95% CI: −2.64 to −1.53, p < 0.001) significantly more than open appendectomy (OA) did. Furthermore, ERAT decreased the incidence of surgical site wound infections (OR: 0.22, 95% CI: 0.13–0.37, p < 0.001) and postoperative complications (OR: 0.16, 95% CI: 0.11–0.21, p < 0.001) more than OA did. This study demonstrated that ERAT is a safe and effective endoscopic treatment modality for acute appendicitis, contributing to a significant reduction in the surgical duration, length of hospital stay, and incidence of surgical site wound infections and postoperative complications. Hence, ERAT has clinical significance and the potential for further application and dissemination.
Surgical site wound infection is one of the most common postoperative complications in orthopaedic clinical practice. This study employed a meta-analysis approach to comprehensively evaluate the effect of operating room nursing interventions on the prevention of surgical site wound infections in orthopaedic surgical patients. A computer search was conducted using PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), VIP, and Wanfang databases from the inception of each database until May 2023 for randomised controlled trials (RCTs) that investigated the application of operating room nursing interventions in orthopaedic surgery. Two reviewers independently screened the literature, extracted data, and assessed study quality. The meta-analysis was conducted using Stata 17.0. A total of 29 studies involving 3567 patients were included, with 1784 patients in the intervention group, and 1783 patients in the control group. The results of the meta-analysis showed that compared with the control group, the use of operating room nursing interventions significantly reduced the incidence of surgical site wound infection after orthopaedic surgery (2.85% vs. 13.24%; odds ratio: 0.18, 95% confidence interval: 0.14–0.25; p < 0.001). Current evidence suggests that operating room nursing interventions reduce the incidence of surgical site wound infections. However, owing to the limited number and low quality of the studies, more high-quality, large-sample RCTs are needed to further verify these findings.
The present study investigated the antimicrobial and anti-biofilm effects of indigenous Lactobacillus probiotic strains on Pseudomonas aeruginosa isolated from burn wound infection in laboratory conditions. The effect of 7 probiotic strains isolated from infant faeces on the pathogenicity factors of P. aeruginosa, including protease, elastase, antibiofilm and antipyocyanin was measured. Also, diffusion methods in the well and micro broth dilution were used to evaluate the antimicrobial activity of probiotics. All tests were performed in triplicate. A negative control and a positive control were used for each test. SPSS version 22 software was used for statistical analysis, and a p < 0.05 was considered statistically significant. A total of 30 clinical isolates of P. aeruginosa were isolated. The elastolytic activity of P. aeruginosa isolates decreased after adding Cell free supernatant (CFS) of each Lactobacillus. L1, L4, L5, and L6 strains had a 100% inhibitory effect on pathogen isolates. L3 and L7 strains had the lowest inhibitory effect. The inhibitory effect of CFS extracted from lactobacilli on protease production by P. aeruginosa. L1, L4, L5, and L6 strains had an inhibitory effect on all tested isolates. L2, L3, and L7 strains had a less inhibitory effect. L4 strain had the highest inhibitory effect on pyocyanin production by P. aeruginosa (50%), followed by L5 (43.3%), L1 (40%), and L6 (23.3%) strains. L3 and L7 strains had no inhibitory effect on the pyocyanin production of P. aeruginosa isolates. It was found that the CFS of 4 isolates (L1, L4, L5, and L6) was the most active extract and had a 100% inhibitory effect against biofilm formation of all P. aeruginosa strains. The L3 strain had the least inhibitory effect against the biofilm formation of pathogens. Overall, this study showed that probiotics could be promising alternatives to combat the pathogenicity of P. aeruginosa in burn wounds.
Diabetic foot ulcer (DFU), a common intractable chronic complication of diabetes mellitus (DM), has a prevalence of up to 25%, with more than 17% of the affected patients at risk of amputation or even death. Vascular risk factors, including vascular stenosis or occlusion, dyslipidemia, impaired neurosensory and motor function, and skin infection caused by trauma, all increase the risk of DFU in patients with diabetes. Therefore, diabetic foot is not a single pathogenesis. Preclinical studies have contributed greatly to the pathogenesis determination and efficacy evaluation of DFU. Many therapeutic tools are currently being investigated using DFU animal models for effective clinical translation. However, preclinical animal models that completely mimic the pathogenesis of DFU remain unexplored. Therefore, in this review, the preparation methods and evaluation criteria of DFU animal models with three major pathological mechanisms: neuropathy, angiopathy and DFU infection were discussed in detail. And the advantages and disadvantages of various DFU animal models for clinical sign simulation. Furthermore, the current status of vitro models of DFU and some preclinical studies have been transformed into clinical treatment programs, such as medical dressings, growth factor therapy, 3D bioprinting and pre-vascularization, Traditional Chinese Medicine treatment. However, because of the complexity of the pathological mechanism of DFU, the clinical transformation of DFU model still faces many challenges. We need to further optimize the existing preclinical studies of DFU to provide an effective animal platform for the future study of pathophysiology and clinical treatment of DFU.
