In addition, Tβ4 treatment significantly promoted wound healing (p < 0.01) and increased the Wnt1 and β-catenin expression levels (p < 0.01). Moreover, FH535 significantly restrained the Wnt/β-catenin pathway-correlated protein levels (p < 0.01) and wound healing. </sec> <sec> <title>Conclusion:</title> Tβ4 can promote scald wound healing in rats and may play a role via evoking Wnt/β-catenin pathway activation. </sec>

Neuroprotective Potential of Bacopa monnieri: Modulation of Inflammatory Signals

Background: To date, much evidence has shown theincreased interest in natural molecules and traditional herbal medicine as alternative bioactive compounds to fight many inflammatory conditions, both in relation to immunomodulation and in terms of their wound healing potential. Bacopa monnieri is a herb that is used in the Ayurvedic medicine tradition for its anti-inflammatory activity. Objective: In this study, we evaluate the anti-inflammatory and regenerative properties of the Bacopa monnieri extract (BME) in vitro model of neuroinflammation. Methods: Neuronal SH-SY5Y cells were stimulated with TNF and IFN and used to evaluate the effect of BME on cell viability, cytotoxicity, cytokine gene expression, and healing rate. Results: Our results showed that BME protects against the Okadaic acid-induced cytotoxicity in SH-SY5Y cells. Moreover, in TNF and IFN primed cells, BME reduces IL-1, IL-6, COX-2, and iNOS, mitigates the mechanical trauma injury-induced damage, and accelerates the healing of wounds. Conclusion: This study indicates that BME might become a promising candidate for the treatment of neuroinflammation.

Molecular Mechanism of Extractum Liquidum Drug Loading Materials on Promoting Chronic Wound Tissue Repair Through Phosphatidylinositol 3 Kinase/Protein Kinase B/Hypoxia Induction Factor 1α Signal Pathway

To solve the shortcomings of traditional Zeji extractum liquidum (traditional Chinese medicine used for wound healing), and to explore the effect of Zeji Etractum Lquidum (ZLE) Nano Materials (ZLENM) on chronic wound (CW) healing and its molecular mechanism. 30 SD rats were divided into 3 groups in random: control group (Ctrl group), model group (CW group), and treatment group (ZLENM group). The results of wound healing rate showed that, in contrast with the CW, the healing rate of back wounds in the ZLENM group was greatly increased on the 7th and 14th days (P < 0.05). In contrast with the Ctrl, the rats in the CW and the ZLENM groups had greatly increased CD31 positive staining on the 7th and 14th days (P < 0.05), and the CW was lower than the ZLENM group (P < 0.05). In contrast with the 7th day, the MVD in the CW and the ZLENM groups was greatly reduced on the 14th day (P < 0.05). Western blot analysis of the expression of related signal molecules showed that the expressions of P-Akt, P-PI3K, HIF-1α, and VEGFR2 protein in the wounds in the CW and ZLENM groups were greatly increased in contrast with the Ctrl (P < 0.05), and CW was lower than ZLENM group (P < 0.05). In conclusion, ZLENM can promote wound healing and increase the number of wound angiogenesis in CW rats. The mechanism is related to the activation of phosphatidylinositol 3 kinase/protein kinase B/hypoxia induction factor 1α (PI3K/AKT/HIF-1α) signaling pathway.

Association of great saphenous vein diameter and clinical severity score after treatment of severe chronic venous insufficiency with foam sclerotherapy

Objectives: to evaluate the association of the greater saphenous vein (GSV) diameter in the treatment of patients with severe chronic venous insufficiency (C6 CEAP classification) with ultrasound-guided polidocanol foam sclerotherapy (UGFS). Methods: A prospective, descriptive and analytical study of 28 patients (30 limbs) that underwent UGFS. Patients were divided into 2 subgroups by GSV diameter (< 8 mm and ≥ 8 mm). Variables analyzed were ulcer healing, clinical intercurrences, clinical CEAP classification, Venous Clinical Severity Score (VCSS), diameter of the treated vein and presence of occlusion or recanalization by Doppler ultrasound. Patients were analyzed at the 1st, 3rd, and 6th months post-treatment. Results: The average age was 68.7 ± 10.5 years, 23 (82,1%) were women, and the average body mass index was 29.2 kg/m2. Although an improvement in VCSS score was observed during follow-up, no significant intergroup difference was noted. Seventeen (56%) limbs presented occlusion of the treated vein at the 1st month, 11 (36%) at the 3rd month, and 9 (30%) at the 6th month of follow-up. The ulcer healing rate was 56,6%. The average ulcer healing time was 90 days. Three (10%) patients presented with ulcer recurrence at the 6th month. Survival analysis showed no significant difference in ulcer healing rate between subgroups after one year of follow-up (log-rank, p = 0,178). Conclusion: There was no difference between the subgroups of large and small VSM diameter in terms of symptom severity. However, significant reduction of VCSS and pain relief was observed after foam sclerotherapy.

The Effectiveness Test Of Wound Healing Daun Gatal (Laportea Decumana) Against Mice (Mus Musculus L)

Daun Gatal (Laportea spp) is one of the shrubs that are widely distributed in Papua from the coast to the mountains. Daun Gatal (Laportea spp) has been used for generations by the Papuan people as painkillers. Daun Gatal (Laportea spp) contains compounds monoxide, tryptophan, histidine, alkaloids, flavonoids, formic acid, and anthraquinones. This content is called "antacid" because it gives a sensation like being bitten by an ant. There are many itchy leaves in the village but often they are just left to dry, wither, die, and even be thrown away. The value of this leaf is very large if it is developed not only as an itchy leaf sheet but as a pharmaceutical product. (Simaremare, et al, 2019). This is supported by several research results stating that itchy leaf extract contains compounds of the alkaloid group, glycosides, steroids (Simaremare, 2014), also contains triterpenoid compounds and formic acid (Chrystomo, et al., 2016) and (Krisna and Santanina, 2019) which states that itchy leaves provide antibacterial activity. The type of research used is experimental research. The research design used was a randomized control group pretest and posttest design. The population in this study was white mice. The samples used in this study were white mice that had met the following inclusion and exclusion criteria. Inclusion criteria were female mice, bodyweight 20-30grams, age 2-4 months while the exclusion criteria. Included in the exclusion criteria in this study were mice that were sick or died in the study conditions. The results of the Extraction of Daun Gatal (Laportea Decumana), namely the itchy leaf sample that has been weighed at a concentration of 25% obtained from a mixture of itching leaf extract (25 grams) added with water (30 ml) produces 18.5 ml. Itchy leaf extract at a concentration of 50 % was obtained from a mixture of itchy leaf extract (50 grams) added with water (30 ml) to produce 20.1 ml. Gatak leaf extract at a concentration of 75% was obtained from a mixture of itching leaf extract (75 grams) added with water (30 ml) to produce 24.3 ml. The extraction method used is extracting the extract of itchy leaves. This method was chosen because the process is simple and does not involve heating so that it can prevent damage to chemical compounds that are not resistant to heating, especially flavonoids contained in itchy leaves. Based on the results of the data on the difference in wound diameter of mice, it showed that Treatment Group 1 with 25% itching leaf extract and Treatment Group 2 with 50% itching leaf extract almost had the same healing rate. Meanwhile, Treatment Group 3 with 75% itching leaf extract had the fastest healing rate among other concentrations. In contrast to Treatment Group 3, the control group had a much longer healing rate among other concentrations.

Nanosilver Dressing in Treating Deep II Degree Burn Wound Infection in Patients with Clinical Studies

Background. Patients’ clinical antibiotic treatment of deep II degree burns usually fails to achieve the ideal effect; in order to avoid the late result in pigmentation, scarring, and even limb dysfunction, it also needs to deal effectively with burn wounds. Aim. The purpose of this study is to evaluate nanosilver dressing in treating deep II degree burn wound infection in patients with clinical studies. Materials and Methods. 106 burn patients were classified into the Sulfadiazine Silver Cream (SSC) group ( n = 53 ) and the Nanosilver Burn Dressing (NSBD) group ( n = 53 ). Both of them received basic wound treatment, and wound healing time and pigmentation fading away time of all patients were recorded. And the wound healing rate of the patients was calculated. Serum levels of tumor necrosis factor alpha (TNF-α) and interleukin-1beta (IL-1β) were detected pre- and posttreatment. Results. After basic treatment for all patients, Sulfadiazine Silver Cream was used in the SSC group, and Nanosilver Burn Dressing was used in the NSBD group. It was observed that after treatment, compared with the SSC group, there was significant efficiency; wound healing rate, healing time, and pigmentation fading away time were shortened in the NSBD group, and IL-1β levels were decreased, and the positive rate of bacterial culture was decreased (all P < 0.05 ). Conclusion. Nanosilver Burn Dressing in treating deep II degree burns can effectively reduce the wound infection and promote wound healing. The curative effect was distinct, which was worthy of popularization and application.

Relationship Between Caregiver Attendance at Wound Clinic Visits and Wound Healing in Patients With Diabetes: A Retrospective Multicenter Evaluation

BACKGROUND: Lower extremity wounds in patients with diabetes are significant and burdensome. PURPOSE: To evaluate retrospectively the correlation between lower limb wound outcomes in patients with diabetes and the presence of a caregiver during clinic visits. METHODS: The study was conducted in 3 outpatient wound centers in North Carolina. Patients (N = 85) were categorized into 2 groups: those who were accompanied by a caregiver at 50% or more of their visits to the wound clinic (n = 30) and those accompanied by a caregiver at fewer than 50% of their visits (n = 55). Data were evaluated using descriptive statistics and 2 sample t-tests. RESULTS: Although significant findings between the 2 groups were seen in age, race, Visit Count, Weeks in Service, Accompanied Count, and percentage of visits accompanied, the strongest meaningful correlation was in the Accompanied group between Percent Accompanied and Visit Count. In this group, the number of accompanied visits was 7.47 (range [standard deviation], 1–23 [5.2]) and the percentage was 87% (range [standard deviation], 52–100 [15]). This was stastically significant and with a moderately negative correlation (P = .04; r = -0.38). CONCLUSION: Despite negative predictors of healing, those who were accompanied by a caregiver at 50% or more of their visits demonstrated a higher healing rate and a lower number of total visits than those who were accompanied by a caregiver at fewer than 50% of their visits.

Fracture-Dedicated Prosthesis Promotes the Healing Rate of Greater Tuberosity in Reverse Shoulder Arthroplasty: A Meta-Analysis

Introduction: Reverse shoulder arthroplasty (RSA) is becoming popular in the treatment of complex proximal humeral fractures (PHFs). Greater tuberosity healing may influence functional outcomes and range of motion (ROM) of shoulder after RSA. In addition, the design of prosthesis may impact the healing rate of greater tuberosity. The purpose of this study is to know: (1) does the healing of greater tuberosity affect the functional outcomes and ROM of shoulder? and (2) does the design of prosthesis affect the healing rate of greater tuberosity?Materials and Methods: PubMed, Ovid/Embase, and the Cochrane Library were searched for studies comparing the clinical outcomes between the healed groups and the non-healed groups after RSA.Results: For functional outcomes, the results showed that the healed group had better Constant scores (CSs) (p &lt; 0.0001). For ROM, the healed group showed better flexion (p &lt; 0.0001), abduction (p = 0.02), and external rotation (p &lt; 0.00001) of shoulder. For the design of prosthesis, the mean healing rate of greater tuberosity (82.7%) in patients with fracture-dedicated prosthesis was higher than those (63.0%) in patients with standard prosthesis. Subgroup analyses showed that the CS (p = 0.12) and abduction (p = 0.96) of patients using fracture-dedicated prostheses were not different between the healed groups and the non-healed groups. Meta-regression showed that there was no significant relationship between the design of prosthesis and CS (p = 0.312), flexion (p = 0.422), or external rotation (p = 0.776).Conclusion: Our meta-analysis showed that the healed groups could obtain better functional outcomes and ROM than the non-healed groups. In addition, fracture-dedicated prostheses promoted the healing rate of greater tuberosity.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020157276, PROSPERO: CRD42020157276.
