RESUMEN
Chemotherapy is a well-established method for treating cancer, but it has limited effectiveness due to its high dosage and harmful side effects. To address this issue, researchers have explored the use of photothermal agent nanoparticles as carriers for precise drug release in vivo. In this study, three different sizes of polydopamine nanoparticles (PDA-1, PDA-2, and PDA-3) were synthesized and evaluated. PDA-2 was selected for its optimal size, encapsulation rate, and drug loading rate. The release of the drug from PDA-2@TAX was tested at different pH and NIR laser irradiation levels. The results showed that PDA-2@TAX released more readily in an acidic environment and exhibited a high photothermal conversion efficiency when exposed to an 808 nm laser. In vitro experiments on ovarian cancer cells demonstrated that PDA-2@TAX effectively inhibited cell proliferation, highlighting its potential for synergistic chemotherapy-photothermal treatment.

Liver disease is a global health problem that affects the well-being of tens of thousands of people. Dihydroquercetin (DHQ) is a flavonoid compound derived from various plants. Furthermore, DHQ has shown excellent activity in the prevention and treatment of liver injury, such as the inhibition of hepatocellular carcinoma cell proliferation after administration, the normalization of oxidative indices (like SOD, GSH) in this tissue, and the down-regulation of pro-inflammatory molecules (such as IL-6 and TNF-α). DHQ also exerts its therapeutic effects by affecting molecular pathways such as NF-κB and Nrf2. This paper discusses the latest research progress of DHQ in the treatment of various liver diseases (including viral liver injury, drug liver injury, alcoholic liver injury, non-alcoholic liver injury, fatty liver injury, and immune liver injury). It explores how to optimize the application of DHQ to improve its effectiveness in treating liver diseases, which is valuable for preparing potential therapeutic drugs for human liver diseases in conjunction with DHQ.

Currently, skin injuries have a serious impact on people's lives and socio-economic stress. Shikonin, a naphthoquinone compound derived from the root of the traditional Chinese medicine Shikonin, has favorable biological activities such as anti-inflammatory, antibacterial, immunomodulatory, anticancer, and wound-healing-promoting pharmacological activities. It has been reported that Shikonin can be used for repairing skin diseases due to its wide range of pharmacological effects. Moreover, the antimicrobial activity of Shikonin can play a great role in food and can also reduce the number of pathogenic bacteria in food. This paper summarizes the research on the pharmacological effects of Shikonin in recent years, as well as research on the mechanism of action of Shikonin in the treatment of certain skin diseases, to provide certain theoretical references for the clinical application of Shikonin, and also to provides research ideas for the investigation of the mechanism of action of Shikonin in other skin diseases.

The skin, the largest organ in the human body, mainly plays a protective role. Once damaged, it can lead to acute or chronic wounds. Wound healing involves a series of complex physiological processes that require ideal wound dressings to promote it. The current wound dressings have characteristics such as high porosity and moderate water vapor permeability, but they are limited in antibacterial properties and cannot protect wounds from microbial infections, which can delay wound healing. In addition, several dressings contain antibiotics, which may have bad impacts on patients. Natural active substances have good biocompatibility; for example, ginsenoside Rg3 has anti-inflammatory, antibacterial, antioxidant, and other biological activities, which can effectively promote wound healing. Some researchers have developed various polymer wound dressings loaded with ginsenoside Rg3 that have good biocompatibility and can effectively promote wound healing and reduce scar formation. This article will focus on the application and mechanism of ginsenoside Rg3-loaded dressings in wounds.

Large bone defects due to trauma, infections, and tumors are difficult to heal spontaneously by the body's repair mechanisms and have become a major hindrance to people's daily lives and economic development. However, autologous and allogeneic bone grafts, with their lack of donors, more invasive surgery, immune rejection, and potential viral transmission, hinder the development of bone repair. Hydrogel tissue bioengineered scaffolds have gained widespread attention in the field of bone repair due to their good biocompatibility and three-dimensional network structure that facilitates cell adhesion and proliferation. In addition, loading natural products with nanoparticles and incorporating them into hydrogel tissue bioengineered scaffolds is one of the most effective strategies to promote bone repair due to the good bioactivity and limitations of natural products. Therefore, this paper presents a brief review of the application of hydrogels with different gel-forming properties, hydrogels with different matrices, and nanoparticle-loaded natural products loaded and incorporated into hydrogels for bone defect repair in recent years.

Skeletons play an important role in the human body, and can form gaps of varying sizes once damaged. Bone defect healing involves a series of complex physiological processes and requires ideal bone defect implants to accelerate bone defect healing. Traditional grafts are often accompanied by issues such as insufficient donors and disease transmission, while some bone defect implants are made of natural and synthetic polymers, which have characteristics such as good porosity, mechanical properties, high drug loading efficiency, biocompatibility and biodegradability. However, their antibacterial, antioxidant, anti-inflammatory and bone repair promoting abilities are limited. Flavonoids are natural compounds with various biological activities, such as antitumor, anti-inflammatory and analgesic. Their good anti-inflammatory, antibacterial and antioxidant activities make them beneficial for the treatment of bone defects. Several researchers have designed different types of flavonoid-loaded polymer implants for bone defects. These implants have good biocompatibility, and they can effectively promote the expression of angiogenesis factors such as VEGF and CD31, promote angiogenesis, regulate signaling pathways such as Wnt, p38, AKT, Erk and increase the levels of osteogenesis-related factors such as Runx-2, OCN, OPN significantly to accelerate the process of bone defect healing. This article reviews the effectiveness and mechanism of biomaterials loaded with flavonoids in the treatment of bone defects. Flavonoid-loaded biomaterials can effectively promote bone defect repair, but we still need to improve the overall performance of flavonoid-loaded bone repair biomaterials to improve the bioavailability of flavonoids and provide more possibilities for bone defect repair.

Diabetes is an epidemic in contemporary society, which seriously affects people's health. Therefore, it is imperative to develop a multifunctional wound dressing that can expedite the healing of diabetic wounds. In this study, quaternized oxidized sodium alginate (QOSA) and carboxymethyl chitosan (CMCS) formed hydrogel through Schiff base reaction, and the composite hydrogel was prepared by adding the antioxidant activity of deer antler blood polypeptide (D). The hydrogel exhibits favorable attributes, including a high swelling ratio, biocompatibility, and noteworthy antioxidant, antibacterial, and hemostatic properties. Finally, it was used to evaluate its effectiveness in repairing diabetic wounds. Upon evaluation, this hydrogel can effectively promote diabetic wound healing. It facilitates cell proliferation at the wound site, mitigates inflammatory responses, and enhances the expression of growth factors at the wound site. This suggests that this hydrogel holds significant promise as an ideal candidate for advanced wound dressings.

The current clinical treatment of diabetic wounds is still based on oxygen therapy, and the slow healing of skin wounds due to hypoxia has always been a key problem in the repair of chronic skin injuries. To overcome this problem, the oxygen-producing matrix CaO2NPS based on the temperature-sensitive dihydromyricetin-loaded hydrogel was prepared. In vitro activity showed that the dihydromyricetin (DHM) oxygen-releasing temperature-sensitive hydrogel composite (DHM-OTH) not only provided a suitable oxygen environment for cells around the wound to survive but also had good biocompatibility and various biological activities. By constructing a T2D wound model, we further investigated the repairing effect of DHM-OTH on chronic diabetic skin wounds and the mechanisms involved. DHM-OTH was able to reduce inflammatory cells and collagen deposition and promote angiogenesis and cell proliferation for diabetic wound healing. These in vitro and in vivo data suggest that DHM-OTH accelerates diabetic wound repair as a novel method to efficiently deliver oxygen to wound tissue, providing a promising strategy to improve diabetic wound healing.

Chitosan is a linear polyelectrolyte with active hydroxyl and amino groups that can be made into chitosan-based hydrogels by different cross-linking methods. Chitosan-based hydrogels also have a three-dimensional network of hydrogels, which can accommodate a large number of aqueous solvents and biofluids. CS, as an ideal drug-carrying material, can effectively encapsulate and protect drugs and has the advantages of being nontoxic, biocompatible, and biodegradable. These advantages make it an ideal material for the preparation of functional hydrogels that can act as wound dressings for skin injuries. This review reports the role of chitosan-based hydrogels in promoting skin repair in the context of the mechanisms involved in skin injury repair. Chitosan-based hydrogels were found to promote skin repair at different process stages. Various functional chitosan-based hydrogels are also discussed.
RESUMEN
Colitis can significantly impact daily life. This study utilized DSS to induce acute colitis in mice and examined the regulatory effect of arabinogalactan (AG). The findings demonstrated that AG intake effectively alleviated the phenotype of DSS-induced colitis in mice and protected against small intestine damage. Furthermore, AG suppressed the secretion of pro-inflammatory factors TNF-α and IL-1ß, while promoting the secretion of anti-inflammatory factor IL-10. It also inhibited the secretion of LPS in serum and MPO in colon tissue. Additionally, AG regulated the NF-κB/MAPK/PPARγ signaling pathway and inhibited the NLRP3 inflammasome signaling pathway, thereby ameliorating DSS-induced colitis inflammation in mice. AG also influenced the metabolism of short-chain fatty acids, particularly butyrate, in the intestinal tract of mice. Moreover, AG modulated and enhanced the composition of intestinal flora in mice with colitis, increasing the diversity of dominant flora and promoting the growth of beneficial bacteria. These results highlight the protective effects of arabinogalactan against colitis and its potential applications in the food industry.

Diabetic wounds are typically chronic wounds and the healing process is limited by problems such as high blood glucose levels, bacterial infections, and other issues that make wound healing difficult. Designing drug-loaded wound dressings is an effective way to promote diabetic wound healing. In this study, we developed an SA/PVA nanofiber (SPS) containing Shikonin (SK) for the treatment of diabetic wounds. The prepared nanofibers were uniform in diameter, had good hydrophilicity and high water vapor permeability, and effectively promoted gas exchange between the wound site and the outside world. The results of in vitro experiments showed that SPS was effective in antimicrobial, antioxidant, and biocompatible. In vivo tests showed that the wound healing rate of mice treated with SPS reached 85.5 %. Immunohistochemical staining results showed that SPS was involved in the diabetic wound healing process through the up-regulation of growth factors (CD31, HIF-1α) and the down-regulation of inflammatory factors (CD68). Western blotting experiments showed that SPS attenuated the inflammation through the inhibition of the IκBα/NF-κB signaling pathway. These results suggest that SPS is a promising candidate for future clinical application of chronic wound dressings.

The wound of diabetes has long-term excessive inflammation leading to wound fibrosis and scar formation. In the process of diabetic wound healing, good wound dressing is required for intervention. In this study, we designed a dihydromyricetin-loaded hydrogel (PCD) based on phellinus igniarius polysaccharide and l-arginine modified chitosan as an alternative material to promote diabetes wound healing. PCD had a uniform porous structure, good thermal stability, excellent mechanical properties, high water absorption, excellent antioxidant and anti-inflammatory activities and good biocompatibility and biodegradability. In addition, in the full-thickness skin trauma model of diabetes, PCD significantly inhibited the JNK signaling pathway to reduce inflammatory response, and significantly down-regulated the expression of TGF-ß1, Smad2, Smad3 and Smad4 to directly inhibit the TGF-ß/Smad signaling pathway to accelerate wound healing and slow down scar formation in diabetes mice. Therefore, PCD has a broad application prospect in promoting diabetes wound healing.

The healing of wounds in diabetics is commonly delayed by recurring infections and persistent inflammation at the wound site. For this reason, we conducted a study using the electrospinning technique to create nanofiber membranes consisting of polyvinylpyrrolidone/chitosan (PVP/CS) and incorporated dihydromyricetin (DHM) into them. Infrared Fourier transform spectroscopy and scanning electron microscopy were used to analyze the nanofiber membrane. Experimental results in vitro have shown that PVP/CS/DHM has exceptional properties such as hydrophilicity, porosity, water vapor transport rate, antioxidant capacity, and antibacterial activity. Moreover, our study has demonstrated that the application of PVP/CS/DHM can significantly improve wound healing in diabetic mice. After an 18-day treatment period, a remarkable wound closure rate of 88.63 ± 1.37 % was achieved. The in vivo experiments revealed that PVP/CS/DHM can promote diabetic wound healing by suppressing the activation of TLR4/MyD88/NF-κB signaling pathway and enhancing autophagy-related protein as well as CD31 and HIF-1α expression in skin tissues. This study showed that PVP/CS/DHM is a promising wound dressing.

Various types of skin wounds pose challenges in terms of healing and susceptibility to infection, which can have a significant impact on physical and mental well-being, and in severe cases, may result in amputation. Conventional wound dressings often fail to provide optimal support for these wounds, thereby impeding the healing process. As a result, there has been considerable interest in the development of multifunctional polymer matrix hydrogel scaffolds for wound healing. This review offers a comprehensive review of the characteristics of polysaccharide-based hydrogel scaffolds, as well as their applications in different types of wounds. Additionally, it evaluates the advantages and disadvantages associated with various types of multifunctional polymer and polysaccharide-based hydrogel scaffolds. The objective is to provide a theoretical foundation for the utilization of multifunctional hydrogel scaffolds in promoting wound healing.

Liver injury caused by type-II diabetes mellitus (DM) is a significant public-health concern worldwide. We used chitosan (CS) to modify dihydromyricetin (DHM)-loaded liposomes (DL) through charge interaction. The effect of CS-modified DL (CDL) on liver injury in mice suffering from DM was investigated in vivo and in vitro. CDL exhibited superior antioxidant capacity and stability. Pharmacokinetic analyses revealed a 3.23- and 1.92-fold increase in the drug concentration-time curve (953.60 ± 122.55 ng/mL/h) in the CDL-treated group as opposed to the DHM-treated group (295.15 ± 25.53 ng/mL/h) and DL-treated group (495.31 ± 65.21 ng/mL/h). The maximum drug concentration in blood (Tmax) of the CDL group saw a 2.26- and 1.21-fold increase compared with that in DHM and DL groups. We observed a 1.49- and 1.31-fold increase in the maximum drug concentration in blood (Cmax) in the CDL group compared with that in DHM and DL groups. Western blotting suggested that CDL could alleviate liver injury in mice suffering from DM by modulating inflammatory factors and the transforming growth factor-ß1/Smad2/Smad3 signaling pathway. In conclusion, modification of liposomes using CS is a viable approach to address the limitations of conventional liposomes and insoluble drugs.

In this paper, a hydrogel material with efficient antibacterial, hemostatic, self-healing, and injectable properties was designed for the treatment of diabetic wounds. Firstly, quaternary ammonium salts were grafted with oxidized sodium alginate, and quaternized oxidized sodium alginate (QOSA) was synthesized. Due to the introduction of quaternary ammonium group it has antibacterial and hemostatic effects, at the same time, due to the presence of aldehyde group it can be reacted with carboxymethyl chitosan (CMCS) to form a hydrogel through the Schiff base reaction. Furthermore, deer antler blood polypeptide (DABP) was loaded into the hydrogel (QOSA&CMCS&DABP), showing good swelling ratio and bacteriostatic effect. In vitro and in vivo experiments demonstrated that the hydrogel not only quickly inhibited hepatic hemorrhage in mice and reduced coagulation index and clotting time in vitro, but also significantly enhanced collagen deposition at the wound site, accelerating wound healing. This demonstrates that the multifunctional hydrogel materials (QOSA&CMCS&DABP) have promising applications in the acceleration of skin wound healing and antibacterial promotion.

The healing of diabetic wounds has long been a significant challenge in the field of medicine. The elevated sugar levels surrounding diabetic wounds create a conducive environment for harmful bacterial growth, resulting in purulent infections that impede the healing process. Thus, the development of a biomaterial that can enhance the healing of diabetic wounds holds great importance. This study developed electrospun dressings for wound healing by combining traditional Chinese medicine and clay. The study utilized electrospinning technology to prepare polyvinyl alcohol (PVA) nanofiber membranes containing ASB and HNTs. These ASB@HNTs-PVA nanofiber membranes demonstrated rapid hemostasis, along with antibacterial and anti-inflammatory properties, facilitating the recovery of type 2 diabetic (T2D) wounds. Various analyses were conducted to assess the performance of the composite nanofiber membrane, including investigations into its biocompatibility and hemostatic abilities through antibacterial experiments, cell experiments, and mouse liver tail bleeding experiments. Western blot analysis confirmed that the composite nanofiber membrane could decrease the levels of inflammatory factors IL-1ß and TNF-α. A type 2 diabetic mouse model was utilized, with wounds artificially induced on the backs of mice. Application of the nanofiber membrane to the wounds further confirmed its anti-inflammatory effects and ability to enhance wound healing in vivo.
RESUMEN
With the improvement of modern living standards, the challenge of diabetic wound healing has significantly impacted the public health system. In this study, our objective was to enhance the bioactivity of taxifolin (TAX) by encapsulating it in liposomes using a thin film dispersion method. Additionally, polyvinyl alcohol/carboxymethyl chitosan-based hydrogels were prepared through repeated freeze-thawing. In vitro and in vivo experiments were conducted to investigate the properties of the hydrogel and its effectiveness in promoting wound healing in diabetic mice. The results of the experiments revealed that the encapsulation efficiency of taxifolin liposomes (TL) was 89.80 ± 4.10 %, with a drug loading capacity of 17.58 ± 2.04 %. Scanning electron microscopy analysis demonstrated that the prepared hydrogels possessed a porous structure, facilitating gas exchange and the absorption of wound exudates. Furthermore, the wound repair experiments in diabetic mice showed that the TL-loaded hydrogels (TL-Gels) could expedite wound healing by suppressing the inflammatory response and promoting the expression of autophagy-related proteins. Overall, this study highlights that TL-Gels effectively reduce wound healing time by modulating the inflammatory response and autophagy-related protein expression, thus offering promising prospects for the treatment of hard-to-heal wounds induced by diabetes.
