Abstract

Objective To investigate the effect of vacuum sealing pressure drainage（VSD） combined with antibacterial dressing on wound healing and the expression of transforming growth factor β1（TGF-β1） and cyclin D1 in granulation tissue of diabetes foot ulcer after artificial dermis transplantation. Methods From January 2019 to June 2021, 60 patients with diabetes foot who were treated in the Burn and Plastic Surgery Department of General Hospital of Southern Theatre Command were selected and randomly divided into the control group and the observation group randomly(n=30, each). The patients in the control group received artificial dermis transplantation; On the basis of the control group, the patients in the observation group were treated with VSD and alginate dressing. The wound appearance of the two groups was observed. The levels of basic fibroblast growth factor(bFGF), epidermal growth factor (EGF) and vascular endothelial growth factor(VEGF) in serum, wound area, VAS score, and the levels of cyclin D1, TGF-β1 in wound tissue were measured. The exudates of the two groups were cultured for bacteria. Results The patients were followed up for 3 months. During the follow-up period, there was no ulcer recurrence in the observation group, but 5 cases in the control group. The scar hyperplasia of the patients in the observation group was light, and the skin had better elasticity and integrity. After treatment, the wound area of both groups was reduced, and that of the observation group was less than that of the control group(P＜0.05). After treatment, the coverage area and coverage rates of granulation tissue in the two groups were increased compared with those before treatment, and the observation group were higher than the control group(P＜0.05). After treatment, the VAS scores of patients in both groups decreased(P＜0.05), and the observation group was lower than that in the control group(P＜0.05). After treatment, the levels of serum bFGF, EGF and VEGF in the two groups increased(P＜0.05), and those in the observation group were higher than those in the control group at each time point(P＜0.05). After treatment, 5 strains of bacteria were cultured in the observation group, the bacterial infection rate was 13.33%(4/30), and 9 strains were cultured in the control group, the bacterial infection rate was 36.67%(11/30). The bacterial infection rate in the observation group was lower than that in the control group(P＜0.05). After treatment, the levels of cyclin D1 and TGF-β1 in wound tissues of both groups increased, and those in the observation group waere higher than those in the control group(P＜0.05). Conclusion VSD combined with antibacterial dressing has a significant effect on wound healing of diabetes foot ulcer after artificial dermis transplantation, which can increase the levels of Cyclin D1 and TGF-β1 in granulation tissue of patients, and increase the levels of bFGF, EGF and VEGF in serum.

Abstract

Acrylic powder coating has excellent anti-aging function and often used as an environmentally friendly topcoat coating. In order to understand its anti-corrosion performance and anti-corrosion mechanism for the purpose of expanding its application, the corrosion behavior and mechanism of intact acrylic powder coatings in marine environment and the defect of acrylic powder coating had been investigated using CASS test, immersion test and AC impedance method. Results showed that the transparent acrylic powder coatings with a thickness of 80 μm and 120 μm respectively had a few blisters on the edge of the scratch after treated by a 240 h CASS test. For the powder coating with a thickness of 120 μm, the maximum and minimum widths of corrosion products around the scratch were about 3.5 mm and 0.5 mm respectively, and the adhesion to the surface was level 0, indicating that the coating had good CASS resistance. After an immersion of 30 d, the amount of corrosion products generated around the scratch of 120 μm coating was smaller than that of 80 μm coating, revealing that 120 μm coating had better immersion resistance. Furthermore, the EIS of scratch specimens in 0.6 mol/L NaCl solution showed that the electric double layer capacitance decreased rapidly firstly and then tended to be stable, and the corrosion rate increased with the prolonging of immersion time. The impedance of the intact acrylic powder coating decreased from about 1010～1011Ω·cm2 to 106 Ω·cm2 after an immersion in 0.6 mol/L NaCl solution for 720 h. The barrier effect of these two kinds of coatings was basically the same after a 360 h immersion. Besides, as the aluminum alloy material covered with acrylic powder coating had poor corrosion resistance, the acrylic powder coating was not suitable to be used alone as the coating system for the automobile aluminum wheel hub or the alumimum alloy material. Hence, it is recommended to use composite coating system as the coating scheme for automobile aluminum alloy wheel hub.

Abstract

To study the characteristics of sandstone crack propagation under hydraulic coupling, sandstone laboratory tests were conducted under different seepage pressures and confining pressures. Under the same effective confining pressure, it is shown that the rock brittleness index becomes higher as the seepage pressure increases, while the crack initiation stress, the crack damage stress, and the peak stress decrease gradually. The initial volumetric strain of the crack decreases, and the volumetric strain of crack propagation decreases firstly and then increases afterward. The growth rate of the crack axial strain and the crack circumferential strain are both increasing that corresponding to the damage stress and the peak stress, however, no obvious relation is observed between the growth rate of the crack volume strain and the seepage pressure. Under the same seepage pressure, the initiation stress, damage stress, and peak stress gradually increase as the effective confining pressure increases. In addition, the growth rates of the crack axial strain, circumferential strain and volumetric strain increase gradually during deformation that corresponds to the crack initiation stress, damage stress and peak stress, respectively. When comparing the different growth rates of crack strain for a tested sandstone specimen, it is found that the strain growth rates have the following order: the crack axial strain > the crack circumferential strain > the crack volume strain.

Abstract

An asymmetrical wound dressing functions akin to human skin by serving as a protective barrier between a wound and its immediate environment. However, significant challenges persist concerning the robust adhesion and asymmetrical adhesion properties of hydrogels, particularly when applied in emergency hemostasis and wound healing contexts. Herein, the study has successfully synthesized hydrogel patches with Janus asymmetric‐adhesion, denoted as HGO‐C, exclusively comprised of natural polymers. This achievement is realized through the assembly of adhesive hydrogel (HGO) and non‐adhesive hydrogel (CGC), thereby amalgamating their distinct functionalities. The non‐adhesive hydrogel component served as a physical shield and safeguarding the wound against contamination, while the adhesive hydrogel, when in contacted with the wound surface, firmly adhered to it, swiftly arresting bleeding and facilitating wound healing. Cytocompatibility tests, hemolysis tests, antibacterial assays, and coagulation assays demonstrated excellent biocompatibility, antibacterial, and hemostatic properties of HGO‐C. Finally, the in vivo experiments, including a liver hemorrhage assay and a wound healing assay, unequivocally showed the rapid hemostatic and enhanced wound healing capabilities of HGO‐C. Consequently, these distinctive hydrogel patches, derived from natural polymers and characterized by their asymmetric adhesion properties, may have great potential for real‐life usage in clinical patients.

Abstract

The true triaxial loading and unloading tests on granite were conducted to obtain the mechanical characteristics of the granite in the construction area of an underground cavern. The stability of the surrounding rock, the characteristic stress, the failure mode and the brittleness characteristics were mainly analyzed in this work. In addition, the evolution laws of total energy and dissipated energy with axial strain were explored. Results show that under the true triaxial loading and unloading stress paths, the failure modes of granite are both tensile and shear composite failure, and characteristics of high damage stress and brittleness are obviously observed. A new brittleness index is proposed to evaluate rock brittleness by using volumetric strain curve. It is found that the brittleness of granite is higher under unloading conditions. In the true triaxial loading test, the change trend of total energy with axial strain goes through three stages: slow increase, rapid increase, and steady increase. In the true triaxial unloading test, the dissipated energy increases rapidly at the moment of unloading, and its proportion in the energy distribution exceeds the elastic strain energy, which becomes the main energy consumption. The energy dissipation value of the granite sample in the loading test is obviously greater than that in the unloading test. It indicates that more energy is required for samples under the loading path to produce damage, which is safer than the unloading path. The particle flow PFC3D is used to simulate the true triaxial loading and unloading test of granite in this study. The failure mode and the crack distribution of the numerical simulation results are basically consistent with results of the laboratory test. Then the numerical model is used to simulate the rapid unloading failure process of granite. It is found that the rock sample particle ejection damage will occur at the end of the model, similar to a rock burst.

Abstract

In this work, the rheological properties of four multi-wall carbon nanotubes (MWCNTs)/polyethylene (PE) composites containing 1 wt.% (mPEC1), 3 wt.% (mPEC3), 5 wt.% (mPEC5), and 10 wt.% (mPEC10) MWCNTs prepared by the masterbatch method were investigated and compared with those of the pure PE. The rheological investigation includes strain sweeping, frequency sweeping, stress relaxation behavior, yield stress, characteristic relaxation time, temperature effect on linear viscoelastic behavior, and gel behavior. It is mainly found that (1) the MWCNTs-MWCNTs interaction resulting in MWCNTs network structure in the PE matrix and the MWCNTs-PE interfacial interaction increase the storage and loss moduli of the MWCNTs/PE composite in comparison with those of pure PE; (2) the time-temperature equivalence principle is applicable only for pure PE and mPEC1; (3) for gel behavior of MWCNTs/PE composite at 160–180 °C, the φ g value decreases with the increase of temperature and the highest S g value is obtained at 170 °C.

Abstract

Objective: The causes and triggering factors of epilepsy are still unknown. The results of genome‐wide association studies can be utilized for a phenome‐wide association study using Mendelian randomization (MR) to identify potential risk factors for epilepsy. Methods: This study utilizes two‐sample MR analysis to investigate whether 316 phenotypes, including lifestyle, environmental factors, blood biomarker, and more, are causally associated with the occurrence of epilepsy. The primary analysis employed the inverse variance weighted (IVW) model, while complementary MR analysis methods (MR Egger, Wald ratio) were also employed. Sensitivity analyses were also conducted to evaluate heterogeneity and pleiotropy. Results: There was no evidence of a statistically significant causal association between the examined phenotypes and epilepsy following Bonferroni correction (p < 1.58 × 10−4) or false discovery rate correction. The results of the MR analysis indicate that the frequency of tiredness or lethargy in the last 2 weeks (p = 0.042), blood uridine (p = 0.003), blood propionylcarnitine (p = 0.041), and free cholesterol (p = 0.044) are suggestive causal risks for epilepsy. Lifestyle choices, such as sleep duration and alcohol consumption, as well as biomarkers including steroid hormone levels, hippocampal volume, and amygdala volume were not identified as causal factors for developing epilepsy (p > 0.05). Conclusions: Our study provides additional insights into the underlying causes of epilepsy, which will serve as evidence for the prevention and control of epilepsy. The associations observed in epidemiological studies may be partially attributed to shared biological factors or lifestyle confounders. [ABSTRACT FROM AUTHOR]
