Abstract	Purpose: Wound repair has always been the basic method of burn surgery, but not all wounds in clinical work can regain both function and appearance. For relatively small wounds with irreversible functional damage accompanied by necrotic bone, joint and tendon exposure, and the wounds in non-functional sites with necrotic bone, tendon exposure and poor surrounding tissue conditions, the value and significance of tissue flap transplantation for wound repair are debatable. This paper discusses a new repair method as a supplementary choice for tissue flap transplantation: autologous granulation tissue and autologous thin split-thickness skin graft, which not only repairs the wound in a simple way but also avoids the cost of tissue flap transplantation. Methods: A total of 11 patients were collected from June 2019 to July 2022, with a total of 20 exposed wounds of bone, joint and tendon necrosis. During the operation, the necrotic exposed bone tissue and the completely necrotic tendon tissue were removed, and the necrotic soft tissue around the wound was completely excised until the wound appeared bleeding. We cut granulation tissue from other parts of the patient's body with a thickness of about 0.5–0.8 mm, cover the deep wound after thorough debridement with granulation tissue, and transplant autologous thin split-thickness skin to the deep wound covered with granulation tissue. The surgical area was compressed and immobilized. Results: In 11 patients, 20 wounds were surgically treated, and the wounds healed 15–25 days after the operation, and no bone tissue, joints, or tendons were exposed. No case underwent secondary surgery after surgery. Some wounds were treated with bedside allograft with the consent of the patient due to a small amount of residual granulation wound healing after transplantation. Conclusion: Using autologous granulation tissue and autologous thin split-thickness skin transplantation to repair some special wounds can not only repair the wounds simply and effectively but also avoid the cost of ...

Abstract	The dicynodont fossils from the Naobaogou Formation of Nei Mongol, China are abundant and diverse but poorly studied. In this article, one nearly complete skeleton and four cranial specimens from the Naobaogou Formation are referred to the dicynodontoid genus Turfanodon as a new species, T. jiufengensis. Previously, Turfanodon was known only from upper Permian sites in Xinjiang and Gansu. The new specimens are referred to Turfanodon based on the following characters: snout tall with steeply sloping profile, anterior tip of the snout squared off, facial region heavily pitted, nasal bosses present as paired swellings near the posterodorsal margin of the external nares, preparietal depressed, intertemporal bar long and narrow, premaxilla contacting frontal, palatal surface of premaxilla exposed in lateral view, and anterior pterygoid keel restricted to the anterior tip of the anterior ramus of the pterygoid. Turfanodon jiufengensis is differentiated from the type species, T. bogdaensis, by a contact of the lacrimal with the septomaxilla, discrete, raised nasal bosses, the dorsal edge of the erupted portion of the canine tusk slightly posterior to the anterior orbital margin, an anterior extension of the lacrimal distinctly shorter than that of the prefrontal, and a premaxillary dorsal surface with a median ridge. The holotype skeleton of T. jiufengensis includes a complete axial column with 50 vertebrae (six cervical, 23 dorsal, six sacral, and 15 caudal). Turfanodon represents the first confirmed tetrapod genus shared by the late Permian faunas of the Junggar and Ordos basins, and appears to be the first dicynodont genus distributed across both tropical and temperate zones (based on paleoclimate reconstructions). Based on tetrapod fossil content, the Naobaogou Formation can be roughly correlated to the Daptocephalus Assemblage Zone of South Africa (255–252 Ma in age).

Abstract	Jimusaria is the first reported Chinese dicynodont, previously only known from Xinjiang. Here we refer two specimens from the Naobaogou Formation, Nei Mongol, China to Jimusaria based on the following features: squamosal separated from supraoccipital by tabular, tabular contacting opisthotic, sharp and thin lateral dentary shelf expanding anteriorly into a thick swelling, nasals fused as single element, rod-like medial bar formed by footplate of epipterygoid connecting to the parabasisphenoid and periotic medially. A new species, J. monanensis, is named based on the diagnostic characters on these two specimens such as distinct caniniform buttress lacking posteroventral furrow, naso-frontal suture forming an anterior directed sharp angle, and converging ventral ridges on posterior portion of anterior pterygoid rami. In Jimusaria, the epipterygoid posteromedially contacts the parabasisphenoid and the periotic as a rod-like bar, a unique morphology unknown in any other dicynodonts. This structure probably increases the stability of the palatal complex. A similar structure might also appear in other dicynodonts as a cartilage connection. The new occurrence of Jimusaria increases the diversity of the tetrapod assemblage from the Naobaogou Formation, and further strengthens the connection between the tetrapod faunas from Nei Mongol and Xinjiang. Based on the current record, Jimusaria is one of the few tetrapod genera which survived in the end-Permian mass extinction.

Abstract	Background: Sepsis is a pathological state resulting from dysregulated immune response in host during severe infection, leading to persistent organ dysfunction and ultimately death. Senescence-associated genes (SAGs) have manifested their potential in controlling the proliferation and dissemination of a variety of diseases. Nevertheless, the correlation between sepsis and SAGs remains obscure and requires further investigation.Methods: Two RNA expression datasets (GSE28750 and GSE57065) specifically related to sepsis were employed to filter hub SAGs, based on which a diagnostic model predictive of the incidence of sepsis was developed. The association between the expression of the SAGs identified and immune-related modules was analyzed employing Cell-type Identification By Estimating Relative Subsets Of RNA Transcripts (CIBERSORT) and Microenvironment Cell Populations-counter (MCP-counter) analysis. The identified genes in each cohort were clustered by unsupervised agreement clustering analysis and weighted gene correlation network analysis (WGCNA).Results: A diagnostic model for sepsis established based on hub genes (IGFBP7, GMFG, IL10, IL18, ETS2, HGF, CD55, and MMP9) exhibited a strong clinical reliability (AUC = 0.989). Sepsis patients were randomly assigned and classified by WGCNA into two clusters with distinct immune statuses. Analysis on the single-cell RNA sequencing (scRNA-seq) data revealed high scores of SAGs in the natural killer (NK) cells of the sepsis cohort than the healthy cohort.Conclusion: These findings suggested a close association between SAGs and sepsis alterations. The identified hub genes had potential to serve as a viable diagnostic marker for sepsis.

Abstract	Objective: The purpose of the study is to investigate the clinical efficacy and long-term prognosis of acupuncture (AP) combined with atorvastatin (ATO) in treating senile essential hypertension (EH) complicated with carotid atherosclerosis (CA). Methods: 108 elderly EH patients with CA admitted to our hospital between January 2018 and September 2018 were enrolled into the study, consisting of 67 patients who received treatment of AP with ATO (AP + ATO group) and 41 patients who received treatment of ATO alone (ATO group). Comparative outcomes included clinical efficacy, blood pressure (BP), the levels of blood lipids and inflammatory factors, carotid intima-media thickness (IMT), the number of unstable carotid intima plaques, the carotid plaque area, and the incidence of adverse reactions. All patients were followed up for 3 years to evaluate their quality of life and the recurrence rate of CA. Results: The AP + ATO group presented a higher efficacy, a declined BP, and lower posttreatment levels of blood lipids and inflammatory factors than the ATO group ( Conclusion: The findings suggested that, for elderly EH patients with CA, treatment of AP with ATO offers better clinical efficacy and safety, which not only can decline the BP, but also can reduce blood lipids and plaque formation, and improve quality of life.

Abstract	Abstract Mobile edge computing (MEC) allows a mobile device to offload tasks to the nearby server for remote execution to enhance the performance of user equipment. A major challenge of MEC is to design an efficient algorithm for task allocation. In contrast to previous work on MEC, which mainly focuses on single-task allocation for a mobile device with only one task to be completed, this paper considers a mobile device with multiple tasks or an application with multiple tasks. This assumption does not hold in real settings because a mobile device may have multiple tasks waiting to execute. We address the problem of task allocation with minimum total energy consumption considering multi-task settings in MEC, in which a mobile device has one or more tasks. We consider the binary computation offloading mode and formulate multi-task allocation as an integer programming problem that is strongly NP-hard. We propose an approximation algorithm and show it is a polynomial-time approximation scheme that saves the maximum energy. Therefore, our proposed algorithm achieves a tradeoff between optimality loss and time complexity. We analyze the performance of the proposed algorithm by performing extensive experiments. The results of the experiments demonstrate that our proposed approximation algorithm is capable of finding near-optimal solutions, and achieves a good balance of speed and quality.

Abstract	The consideration of isolation valves and segments is essential for evaluating the water service and resilience of water distribution systems when shutdowns are required under pipe failure. However, little work has been done on assessing the resilience response and intervention based on segments. This study investigates the impact of intervention (valve density and protection of critical segment) and response (recovery time and recovery sequence) on system resilience taking valve layout into consideration. An algorithm to identify segments based on the graph theory is proposed. Resilience is quantified using the satisfactory rate of the water supply demand. Critical segments are ranked based on resilience analysis. The resilience evaluation method is applied to a case study network. It is found that valve optimization can significantly reduce the number of valves without considerably decreasing the resilience performance. Valve density and the protection of critical segment can reduce the severity of pipe failure, while efficient recovery response can reduce the severity and shorten the duration of pipe failure simultaneously. The criticality of segments depends on the segment location and hydraulic interdependency among segments. HIGHLIGHTS The evaluation of resilience response and intervention based on valve segments is carried out for understanding the performance of water distribution systems under pipe failure.; A segment identification method is proposed to identify all segments simultaneously for visualization and resilience analysis.; Segment criticality and recovery sequence are subject to network topology and hydraulic interdependency among segments.;

Abstract	Citrus fruits are one of the popular fruit crops around the world. However, the consumption and industrial process of citrus fruits yield a large amount of wastes, especially peels, seeds and pomace. Citrus processing wastes are normally used as animal feed or even discarded directly, which have caused serious environmental pollution and economical loss. Since citrus processing wastes contain numerous phytochemicals and bioactive components, they have good application potentials in food packaging sectors. In recent years, the development of food packaging films based on citrus processing wastes has received increasing attention. Food packaging films can be prepared by using citrus processing wastes in different forms, such as the direct use of citrus peel powder and the indirect use of active compounds extracted from the wastes (especially pectin, essential oils and seed extracts). The incorporation of citrus processing wastes or their extracts significantly alters the physical properties and enhances the antioxidant and antimicrobial activities of the films. The developed films have wide applications in the preservation of aquatic products, baked food, fruits, vegetables and meats. In this review, recent advances on the development of food packaging films based on citrus processing wastes are introduced. The preparation methods, physical and functional properties, and the applications of citrus processing wastes-based packaging films are summarized.

Abstract	In this work, we have reported the biogenic supported silver nanoparticles over surface of magnetic Fe3O4 nanoparticles by using Pomegranate peel extract. The extract was used as a green reducing agent and an excellent stabilizer of the synthesized Ag NPs. Physicochemical characterization of the as-synthesized Fe3O4/Ag NPs was carried out through electron microscopy (SEM and TEM), energy dispersive X-ray spectroscopy (EDX), elemental mapping (WDX), vibrating sample magnetometer (VSM), X-ray diffraction (XRD) and inductively coupled plasma-optical emission spectroscopy (ICP-OES). The anti-ovarian cancer effects of biologically synthesized Fe3O4/Ag NPs against ovarian cancer cell lines were assessed. The anti-ovarian cancer properties of the Fe3O4/Ag NPs could significantly remove NIH: OVCAR-3‎, ES-2‎, TOV-21G cancer cell lines in a time and concentration-dependent manner by MTT assay. The antioxidant activity of Fe3O4/Ag NPs was determined by DPPH method. The Fe3O4/Ag NPs showed the high antioxidant activity according to the IC50 value. It seems that the anti-human ovarian cancer effect of recent nanoparticles is due to their antioxidant effects. After clinical study, Fe3O4/Ag NPs bio-composite can be utilized as an efficient drug in the treatment of human ovarian cancer in humans.
