RESUMO

BACKGROUND: Acute ankle injuries are commonly seen in emergency rooms, with significant social impact and potentially devastating consequences. While several clinical practice guidelines (CPGs) related to ankle injuries have been developed by various organizations, there is a lack of critical appraisal of them. The purpose of this systematic review is to identify and critically appraise evidence-based clinical practice guidelines (EB-CPGs) related to acute ankle injuries in adults. METHOD: We conducted searches in the Cochrane Library, MEDLINE, EMBASE databases, WHO, and reviewed 98 worldwide orthopedic association websites up until early 2023. Two authors independently applied the inclusion and exclusion criteria, and each evidence-based clinical practice guideline (EB-CPG) underwent independent critical appraisal of its content by all four authors using the Appraisal of Guidelines for REsearch and Evaluation (AGREE II) instrument. AGREE II scores for each domain were then calculated. RESULTS: This review included five evidence-based clinical practice guidelines. The mean scores for all six domains were as follows: Scope and Purpose (87.8%), Stakeholder Involvement (69.2%), Rigour of Development (72.5%), Clarity of Presentation (86.9%), Applicability (45.6%), and Editorial Independence (53.3%). CONCLUSION: The number of EB-CPGs related to ankle injuries are limited and the overall quality of the existing evidence-based clinical practice guidelines (EB-CPGs) for ankle injuries is not strong, with three of them being outdated. However, valuable guidance related to Ottawa rules, manual therapy, cryotherapy, functional supports, early ambulation, and rehabilitation has been highlighted. Challenges remain in areas such as monitoring and/or auditing criteria, consideration of the target population's views and preferences, and ensuring editorial independence. Future guidelines should prioritize improvements in these domains to enhance the quality and relevance of ankle injury management. SYSTEMATIC REVIEW: Systematic review.

RESUMO

With the rapid development of the national economy, power security is very important for the security of the country and people's happiness. Electricity is an important energy source for a country. Even if the power system malfunctions for a short period of time, it would cause incalculable losses to social production and people's lives. Among them, one of the most important reasons for power system faults is the occurrence of power line faults, so diagnosing faulty lines has great research significance. On the basis of analyzing the structure and working principle of the deep learning model convolutional neural network (CNN), this article used the CNN model to diagnose faults in power lines and analyzed the simulation results. It was found that different CNN structures have different fault diagnosis accuracy for power lines. The fewer the number of batches in the network structure and the more the number of training sessions, the higher its fault determination accuracy. In the power line fault diagnosis based on three deep learning algorithms, the CNN has the highest stable fault diagnosis accuracy of 100%; the recursive neural network has the second stable fault diagnosis accuracy of 93.4%; the deep belief network has the lowest stable fault diagnosis accuracy of 91.5%. In the comparison of power line fault diagnosis stability, the accuracy standard deviation of CNN is close to 0, and they are also the most stable in power circuit fault diagnosis. The stability of algorithmic recurrent neural networks is between the two, and the accuracy standard deviation of deep belief networks is 1.84% when trained 12 times. Their fault diagnosis stability is also the worst.

RESUMO

Sterile tissue injury, such as by acute kidney injury, is common in the clinic and frequently associated with respiratory compromise and hypoxemia. We previously described signaling components released by the injured kidney that drive a remote inflammatory response in the lung. How this caused the resultant hypoxemia remained unclear. Here, we report that sterile kidney tissue injury induces rapid intravascular "neutrophil train" formation in lung capillaries, a novel form of neutrophil swarming. Rapid swarming is enhanced by decreased deformability of circulating neutrophils that impedes their lung capillary passage. Classical lung monocytes are required for neutrophil train formation and release CXCL2 to attract and retain stiffened neutrophils in lung capillaries which reduces capillary perfusion. We thus discovered a novel feature of kidney-lung crosstalk after sterile kidney tissue injury, capillary perfusion deficits that lead to reduced oxygenation despite proper alveolar function and ventilation, unlike in infectious inflammatory lung processes, such as bacterial pneumonia.

RESUMO

Tendon regeneration is greatly influenced by the oxidant and the inflammatory microenvironment. Persistent inflammation during the tendon repair can cause matrix degradation, tendon adhesion, and excessive accumulation of reactive oxygen species (ROS), while excessive ROS affect extracellular matrix remodeling and tendon integration. Herein, we used tannic acid (TA) to modify a decellularized tendon slice (DTS) to fabricate a functional scaffold (DTS-TA) with antioxidant and anti-inflammatory properties for tendon repair. The characterizations and cytocompatibility of the scaffolds were examined in vitro. The antioxidant and anti-inflammatory activities of the scaffold were evaluated in vitro and further studied in vivo using a subcutaneous implantation model. It was found that the modified DTS combined with TA via hydrogen bonds and covalent bonds, and the hydrophilicity, thermal stability, biodegradability, and mechanical characteristics of the scaffold were significantly improved. Afterward, the results demonstrated that DTS-TA could effectively reduce inflammation by increasing the M2/M1 macrophage ratio and interleukin-4 (IL-4) expression, decreasing the secretion of interleukin-6 (IL-6) and interleukin-1ß (IL-1ß), as well as scavenging excessive ROS in vitro and in vivo. In summary, DTS modified with TA provides a potential versatile scaffold for tendon regeneration.

RESUMO

Pseudopodium-enriched atypical kinase 1 (PEAK1) has been demonstrated to be upregulated in human malignancies and cells. Enhanced PEAK1 expression facilitates tumor cell survival and chemoresistance. However, the role of PEAK1 inhibition to anaplastic thyroid carcinoma cell (ATC) and vemurafenib resistance is still unknown. Here, we observed that targeting PEAK1 inhibited cell viability and colony formation, but not cell apoptosis in both of the 8505C and Hth74 cells in vitro. Targeting PEAK1 sensitized 8505C and Hth74 cells to vemurafenib by inducing cell apoptosis, and thereby decreasing cell viability. Mechanistically, vemurafenib treatment upregulated PEAK1 expression. Combined PEAK1 depletion and Vemurafenib treatment upregulated Bim expression. Targeting PEAK1 sensitized vemurafenib-induced apoptosis by upregulating Bim. In conclusion, vemurafenib resistance in ATC cells harboring BRAFV600E is associated with PEAK1 activation, resulting in the inhibition of pro-apoptotic Bim protein. Therefore, targeting PEAK1 may be an effective strategy to sensitize ATC harboring BRAFV600E to vemurafenib.

RESUMO

ObjectiveTo evaluate the methodological and reporting quality of clinical practice guidelines for Chinese patent medicine (CPM) with internationally recognized tools the appraisal of guidelines for research and evaluation (AGEREE) Ⅱ and reporting items for practice guidelines in healthcare (RIGHT), thereby providing refe-rence for the clinical application and future development of CPM guidelines. MethodsDatabases including CNKI, VIP, Wanfang and Sinomed were searched for CPM guidelines, as well as medlive.cn, websites of China Association of Chinese Medicine and Chinese Medical Association, and reference lists of the included papers. The quality of the guidelines was evaluated using the AGREE Ⅱand RIGHT tools, and consistency tests were performed using Interclass Correlation Coefficient, and descriptive analysis and chi-square test were used to analyze the reporting rate for each domain and the average score for each item. ResultsFinally, 140 CPM guidelines were included, of which 51 were disease-oriented and 89 were drug-oriented, all of which were issued by China. For 51 disease-oriented CPM guidelines, the highest average score of all six AGREE Ⅱ domains was 73.32% for clarity, and the lowest was 26.80% for application; for 89 drug-oriented CPM guidelines, the highest average score was 55.62% for scope and purpose, and the lowest was 31.32% for rigour of development. In terms of the seven domains of the RIGHT checklist, the highest reporting rate was 68.26% for background, and lowest was 27.45% for other areas regarding the disease-oriented CPM guidelines; the highest reporting rate was 61.31% for background, and the lowest was 4.49% for other areas regarding drug-oriented CPM guidelines. The average reporting rate was higher for disease-oriented than drug-oriented CPM guidelines in three domains of AGREE Ⅱ (rigour of development, clarity of presentation, editorial independence), as well as four domains of RIGHT checklist (basic information, evidence, funding and declaration and management of interests, and other areas). ConclusionThe overall methodology and reporting quality of the current CPM guidelines still need to be improved. It is recommended that future guideline development teams should strictly refer to the AGREE Ⅱ and RIGHT checklist, and take into account of the characteristics of CPM guidelines and relevant methodo-logical suggestions in the development and reporting of CPM guidelines, thereby guiding the clinical use of CPM in a better way.

RESUMO

Recommendation formation is a key component of clinical practice guidelines for Chinese patent medicine (CPM), and should encompass the determination of the strength and direction of the recommendation, the rationale for the recommendation, and the methodology for implementing the recommendation. Recommendations can be formed through formal consensus and informal consensus. The strength and direction of recommendations for CPM guidelines should be determined by considering the quality of evidence for CPMs, the priority of the clinical questions, the pros and cons of efficacy and adverse effects, patient acceptance, the feasibility of the recommendation and the availability of resources, social fairness, economic benefits, and other influencing factors. In order to better guide guideline developers to consider these factors more rationally, this article provideed a detailed explanation of each factor in the context of the characteristics of TCM.

RESUMO

Recommendations for Chinese patent medicine (CPM) based on key information on rational drug use are one of the important conditions for enhancing guideline enforceability as well as facilitating guideline implementation. In this study, we discussed in detail of the key information on the rational use of CPM in five aspects, which are dosage, drug discontinuation, drug-drug and drug-food interactions, safety and economy. Following the process of multi-source search, synthesis and prioritization, it is suggested to collect key information on the rational use of CPM from a multi-source search of drug instructions, policy documents, literature, and clinical experts' experiences. Then the searched information should be summarized and prioritized with the principle that taking drug instructions as the basis and other-sources information for check and supplementation. Finally, methodological recommendations for the retrieval and synthesis of key information on rational drug use in guideline recommendations has been formed.

RESUMO

The retrieval and evaluation of evidence is the basis for the development of clinical practice guidelines for Chinese patent medicine. As traditional Chinese medicine has a different development trajectory and utilization characteristics from modern medicine, there is certain differences in terms of evidence composition, retrieval and integration.This paper discussed multi-source body of evidence on Chinese patent medicine based on modern evidence-based medicine and ancient medical literature, and summarized the retrieval strategy as well as the possible problems and solving methods. For different types of evidence on Chinese patent medicine, the corresponding evaluation tools have been recommended, and the order to integrate the evidence based on the quality of the evidence from high to low is suggested. Finally, a multi-source based evidence retrieval-evaluation-integration scheme for Chinese patent medicine has been formed, which will provide a methodological reference for practitioners in the development of clinical practice guidelines for Chinese patent medicine.

RESUMO

The identification of clinical questions for clinical practice guidelines of Chinese patent medicine (CPM) is important for subsequent evidence retrieval, evaluation of evidence quality, formation of recommendations. This paper described a methodological proposal for the identification of clinical questions for CPM guidelines to highlight the characteristics of Chinese patent medicine and reflect its effect in specific stage of the disease. Considering four aspects, namely, the drug of Chinese patent medicine (D), the specific disease stage (S), comparison (C), and specific outcome (O), DSCO framework has been proposed to formulate the clinical questions. Multi-source information through scientific research, policy or standard documents, and clinical data are suggested for collecting clinical questions, and clear selection criteria should be set to finalize the clinical questions to be addressed by the guideline. In addition, the above process needs to be transparently and publicly reported in order to ensure the clarity and completeness of the guidelines.

RESUMO

This paper summarized the key points and methods in terms of the establishment of the guideline working group and the management of conflict of interests, trying to provide reference for the development of clinical practice guidelines for Chinese patent medicine (CPM). The establishment of the working group is the first important step for developing CPM guidelines. Considering the characteristics of the clinical practice guidelines for CPM, this study suggests that the three key elements of ‘multidisciplinarity’, ‘clinical relevance’ and ‘geographical representativeness’ should be put focus on when forming the working group. The guideline advisory committee, clinical expert group, evidence systematic evaluation group, secretary group and the external review group should be established. All group members should clarify the conflict of interest, and the process and management method of the conflict of interest should be clearly reported.

RESUMO

The irrational use of Chinese patent medicines (CPM) is becoming more and more prominent, which makes the demand for clinical practice guidelines of CPM gradually increase. In order to make domestic scholars understand the latest developments and existing problems of the CPM guidelines, and promote its development, this paper introduced the concept of CPM guidelines, summarized the characteristics of the two development modes, namely “taking CPM as the key” and “taking disease/syndrome as the key”, and analyzed the current methodological status of developing and reporting CPM guidelines. Based on the existed problems, three suggestions have been put forward to optimize the quality of CPM guidelines, which were clarifying the target users and scope of CPM guidelines, establishing an open and transparent mechanism of the personnel involvement and process steps, and formulating implementable and operable recommendations for the use of CPM.

RESUMO

Bioadhesives have been widely used in hemostasis and tissue repair, but the overmoist and wet nature of wound surface (due to the presence of blood and/or wound exudate) has led to poor wet adhesion of bioadhesives, which interrupts the continuous care of wounds. Here, a thirsty polyphenolic silk granule (Tan@SF-pwd-hydro), which absorbs blood and exudate to self-convert to robust bioadhesives (Tan@SF-gel-hydro) in situ, was facilely developed in this study for enhanced wet adhesion toward hemostasis and tissue repair. Tan@SF-pwd-hydro could shield wounds' wetness and immediately convert itself to Tan@SF-gel-hydro to seal wounds for hemorrhage control and wound healing. The maximum adhesiveness of Tan@SF-gel-hydro over wet pigskin was as high as 59.8 ± 2.1 kPa. Tan@SF-pwd-hydro is a promising transformative dressing for hemostasis and tissue repair since its hemostatic time was approximately half of that of the commercial hemostatic product, CeloxTM, and its healing period was much shorter than that of the commercial bioadhesive product, TegadermTM. This pioneering study utilized adverse wetness over wounds to arouse robust adhesiveness by converting thirsty granules to bioadhesives in situ, creatively turning adversity into opportunities. The facile fabrication approach also offers new perspectives for manufacturing sustainability of biomaterials.

RESUMO

The diabetic chronic wound healing is extremely restricted by issues such as hyperglycemia, excessive exudate and reactive oxygen species (ROS), and bacterial infection, causing significant disability and fatality rate. Herein, the chitosan/silk fibroin nanofibers-based hierarchical 3D sponge (CSSF-P/AuGCs) with effective exudate transfer and wound microenvironment modulation are produced by integrating cascade reactor (AuGC) into sponge substrates with parallel-arranged microchannels. When applied to diabetic wounds, the uniformly parallel-arranged microchannels endow CSSF-P/AuGCs with exceptional exudate absorption capacity, keeping the wound clean and moist; additionally, AuGCs efficiently depletes glucose in wounds to generate H2O2, which is then converted into HClO via cascade catalytic reaction to eliminate bacterial infection and reduce inflammation. Experiments in vitro demonstrated that the antibacterial activity of CSSF-P/AuGCs against S. aureus and E. coli was 92.7 and 94.27 %, respectively. Experiments on animals indicated that CSSF-P/AuGC could cure wounds in 11 days, displaying superior wound-healing abilities when compared to the commercial medication Tegaderm™. This versatile CSSF-P/AuGCs dressing may be an attractive choice for expediting diabetic wound healing with little cytotoxicity, providing a novel therapeutic method for establishing a favorable pathological microenvironment for tissue repair.

RESUMO

Elevated levels of circulating tumor necrosis factor receptors 1 and 2 (cTNFR1/2) predict chronic kidney disease (CKD) progression; however, the mechanisms of their release remain unknown. Whether acute kidney injury (AKI) drives cTNFR1/2 elevations and whether they predict disease outcomes after AKI remain unknown. In this study, we used AKI patient serum and urine samples, mouse models of kidney injury (ischemic, obstructive, and toxic), and progression to fibrosis, nephrectomy, and related single-cell RNA-sequencing datasets to experimentally test the role of kidney injury on cTNFR1/2 levels. We show that TNFR1/2 serum and urine levels are highly elevated in all of the mouse models of kidney injury tested, beginning within one hour post injury, and correlate with its severity. Consistent with this, serum and urine TNFR1/2 levels are increased in AKI patients and correlate with the severity of kidney failure. Kidney tissue expression of TNFR1/2 after AKI is only slightly increased and bilateral nephrectomies lead to strong cTNFR1/2 elevations, suggesting the release of these receptors by extrarenal sources. The injection of the uremic toxin indoxyl sulfate in healthy mice induces moderate cTNFR1/2 elevations. Moreover, TNF neutralization does not affect early cTNFR1/2 elevations after AKI. These data suggest that cTNFR1/2 levels in AKI do not reflect injury-induced TNF activity, but rather a rapid response to loss of kidney function and uremia. In contrast to traditional disease biomarkers, such as serum creatinine or BUN, cTNFR1/2 levels remain elevated for weeks after severe kidney injury. At these later timepoints, cTNFR1/2 levels positively correlate with remaining kidney injury. During the AKI-to-CKD transition, elevations of TNFR1/2 kidney expression and of cTNFR2 levels correlate with kidney fibrosis levels. In conclusion, our data demonstrate that kidney injury drives acute increases in cTNFR1/2 serum levels, which negatively correlate with kidney function. Sustained TNFR1/2 elevations after kidney injury during AKI-to-CKD transition reflect persistent tissue injury and progression to kidney fibrosis.

RESUMO

Tissue adhesives have been widely used in biomedical applications. However, the presence of a hydrated layer on the surface of wet tissue severely hinders their adhesion capacities, resulting in ineffective wound treatment. To address this issue, a dry particle dressing (plas@SF/tann-hydro-pwd) capable of removing the hydrated layer and converting in situ to bioadhesives (plas@SF/tann-hydro-gel) was fabricated via simple physical mixing based on the hydrophobic-hydrogen bonding synergistic effect and Schiff-base reaction. It was found that the plas@SF/tann-hydro-gel bioadhesive, which was changed from plas@SF/tann-hydro-pwd dressing by adsorption of water, exhibited good wet adhesion to diverse biological tissues. In addition, the wet adhesion qualities of the plas@SF/tann-hydro-gel adhesive was studied under a variety of demanding conditions, including a wide range of temperatures, varying pH levels, highly concentrated salt solutions, and simulated fluids. Experiments on animals had showed that the adhesive plas@SF/tann-hydro-gel has superior wet adhesion qualities and superior wound healing properties compared to the commercial product Tegaderm™. This study develops a new wet-adhesion technique employing dry particle dressing to eliminate the hydrated layer over wet tissues for the in situ creation of gel bioadhesives for wound healing.

RESUMO

This study aimed to investigate the mechanism of "Trichosanthis Fructus-Allii Macrostemonis Bulbus" (GX) on phlegm and blood stasis syndrome (PBSS) rats combining the methods of network pharmacology and experimental verification. Animal experiment ethical requirements were approved by the Ethical Committee Experimental Animal Center of Anhui University of Chinese Medicine (grant number: AHUCM-rats-2021070). Based on the HPLC-Q-TOF-MS analysis and database, 69 chemical constituents of GX and 163 targets of GX for the treatment of phlegm and blood stasis-related cardiovascular diseases were obtained. Then, key targets such as serine/threonine kinase 1 (Akt1), tumor necrosis factor (TNF), interleukin 6 (IL6), vascular endothelial growth factor A (VEGFA), cellular tumor antigen p53 (Tp53) were screened. Pathway analysis showed that the targets of GX in the treatment of phlegm and blood stasis-relate cardiovascular diseases were mainly involved in PI3K/Akt signaling pathway, sphingolipid metabolism, platelet activation, hypoxia inducible factor-1 (HIF-1), ras-proximate-1 (rap1) and other signaling pathways. In addition, molecular docking analysis showed that apigenin, cucurbitacin D, linolenic acid and kaempferol and other key components had potential binding ability with Akt1, TNF, IL6, VEGFA and Tp53. In the animal experiments, compared to the phlegm and blood stasis syndrome group, GX could significantly improve the traditional Chinese medicine syndrome score, blood lipid, vascular endothelial structure disorders and reduce serum endothelin-1 (ET-1) level, increase serum nitric oxide (NO) and endothelial nitric oxide synthase (eNOS) levels, which could restore aortic endothelial function. In addition, the expression of intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in aorta could be significantly reduced, which could improve the vascular endothelial injury of aorta. Western blot revealed that GX could significantly decrease the phosphorylation levels of phosphoinositide 3-kinase (PI3K) and Akt in aorta. This study revealed the mechanism of GX in treatment of phlegm and blood stasis-relate cardiovascular diseases is consistent with the characteristics of multiple ingredients, multiple targets and multiple pathways. In addition, this study also clarified that the reversal of pathological of phlegm and blood stasis syndrome rats may be related to GX inhibiting PI3K/Akt signaling pathway, which could improve vascular inflammation and vascular endothelial function injury.
