Abstract
Pathological scar is a classic problem in plastic and reconstructive surgery. Although the researches on pathological scar have been conducted for decades, the way to go to address this thorny problem still remains challenging. To the best of our knowledge, few bibliometric analysis concerning pathological scar have been reported. In this study, we set out to employ bibliometric and visual analysis to offer research status and trends of pathological scar over the period 2001-2021. All publications covering pathological scar during 2001-2021 were retrieved and extracted from the Web of Science database. We applied VOSviewer software to evaluate the keywords and research hotpots, and the online tool (http://bibliometric.com/) was used to carried out the publication trends analysis. A total of 2221 pathological scar-related articles were identified over the period 2001-2021. China is the country which had the largest volume of publications (819, 36.87%), followed by the United States (416, 18.73%), Japan (144, 6.48%), Korea (142, 6.39%), and England (118, 5.31%). Among the institutions and journals, Shanghai Jiao Tong University (167) and Wound Repair and Regeneration (85) accounted for the most papers related to pathological scar, respectively. Professor Bayat A, who had the most citation frequency (2303), made great contribution in pathological scar field. "Fibroblast", "expression", and "proliferation" were identified as the pathological scar research hotspot through analysis of the keywords. In terms of publication, China ranked first all over the world, but the numbers of publication are inconsistent with the citation frequency, ranking first and second, respectively. Shanghai Jiao Tong University and journal Wound Repair and Regeneration stand for the highest level of research in this field to a certain extent. In the early stage, the research focus was mainly on the prevention, treatment, and risk factors for recurrence of pathological scar from cases. In the later stage, the research focus was on the comprehensive management, in which the mechanism research was in-depth to the molecular and gene level.

Abstract
Objectives Keloids are benign fibroproliferative tumors that display many cancer‐like characteristics, such as progressive uncontrolled growth, lack of spontaneous regression, and extremely high rates of recurrence. Polo‐like kinase 4 (PLK4) was recently identified as a master regulator of centriole replication, and its aberrant expression is closely associated with tumorigenesis. This study aimed to investigate the expression and biological role of PLK4 in the pathogenesis of keloids. Materials and Methods We evaluated the expression of PLK4 in keloids and adjacent normal skin tissue samples. Then, we established PLK4 knockdown and overexpression cell lines in keloid fibroblasts (KFs) and normal skin fibroblasts (NFs), respectively, to investigate the roles of PLK4 in the regulation of proliferation, migration, invasion, apoptosis, and cell cycle in KFs. Centrinone B (Cen‐B), a highly selective PLK4 inhibitor, was used to inhibit PLK4 activity in KFs to evaluate the therapeutic effect on KFs. Results We discovered that PLK4 was overexpressed in keloid dermal samples and KFs compared with adjacent normal skin samples and NFs derived from the same patients. High PLK4 expression was positively associated with the proliferation, migration, and invasion of KFs. Furthermore, knockdown of PLK4 expression or inhibition of PLK4 activity by Cen‐B suppressed KF growth, induced KF apoptosis via the caspase‐9/3 pathway, and induced cell cycle arrest at the G0/G1 phase in vitro. Conclusions These findings demonstrate that PLK4 is a critical regulator of KF proliferation, migration, and invasion, and thus, Cen‐B is a promising candidate drug for keloid treatment.

Abstract
In recent years, researchers are exploring innovative green materials fabricated from renewable natural substances to meet formulation needs. Among them, biopolymers like chitosans and biosurfactants such as sugar fatty acid esters are of potential interest due to their biocompatibility, biodegradability, functionality, and cost-effectiveness. Both classes of biocompounds possess the ability to be efficiently employed in wound dressing to help physiological wound healing, which is a bioprocess involving uncontrolled oxidative damage and inflammation, with an associated high risk of infection. In this work, we synthesized two different sugar esters (i.e., lactose linoleate and lactose linolenate) that, in combination with chitosan and sucrose laurate, were evaluated in vitro for their cytocompatibility, anti-inflammatory, antioxidant, and antibacterial activities and in vivo as wound care agents. Emphasis on Wnt/β-catenin associated machineries was also set. The newly designed lactose esters, sucrose ester, and chitosan possessed sole biological attributes, entailing considerable blending for convenient formulation of wound care products. In particular, the mixture composed of sucrose laurate (200 µM), lactose linoleate (100 µM), and chitosan (1%) assured its superiority in terms of efficient wound healing prospects in vivo together with the restoring of the Wnt/β-catenin signaling pathway, compared with the marketed wound healing product (Healosol®), and single components as well. This innovative combination of biomaterials applied as wound dressing could effectively break new ground in skin wound care.

Abstract
Background Acute myocardial infarction (AMI)-induced excessive myocardial fibrosis exaggerates cardiac dysfunction. However, serum Wnt2 or Wnt4 level in AMI patients, and the roles in cardiac fibrosis are largely unkown. Methods AMI and non-AMI patients were enrolled to examine serum Wnt2 and Wnt4 levels by ELISA analysis. The AMI patients were followed-up for one year. MI mouse model was built by ligation of left anterior descending branch (LAD). Findings Serum Wnt2 or Wnt4 level was increased in patients with AMI, and the elevated Wnt2 and Wnt4 were correlated to adverse outcome of these patients. Knockdown of Wnt2 and Wnt4 significantly attenuated myocardial remodeling and cardiac dysfunction following experimental MI. In vitro, hypoxia enhanced the secretion and expression of Wnt2 and Wnt4 in neonatal rat cardiac myocytes (NRCMs) or fibroblasts (NRCFs). Mechanistically, the elevated Wnt2 or Wnt4 activated β-catenin /NF-κB signaling to promote pro-fibrotic effects in cultured NRCFs. In addition, Wnt2 or Wnt4 upregulated the expression of these Wnt co-receptors, frizzled (Fzd) 2, Fzd4 and (ow-density lipoprotein receptor-related protein 6 (LRP6). Further analysis revealed that Wnt2 or Wnt4 activated β-catenin /NF-κB by the co-operation of Fzd4 or Fzd2 and LRP6 signaling, respectively. Interpretation Elevated Wnt2 and Wnt4 activate β-catenin/NF-κB signaling to promote cardiac fibrosis by cooperation of Fzd4/2 and LRP6 in fibroblasts, which contributes to adverse outcome of patients with AMI, suggesting that systemic inhibition of Wnt2 and Wnt4 may improve cardiac dysfunction after MI.

Abstract
Skin fibrosis is the excessive deposition of extracellular matrix in the dermis. Cutaneous fibrosis can occur following tissue injury, including burns, trauma, and surgery, resulting in scars that are disfiguring, limit movement and cause significant psychological distress for patients. Many molecular pathways have been implicated in the development of skin fibrosis, yet effective treatments to prevent or reverse scarring are unknown. The Wnt signaling pathways are known to play an important role in skin homeostasis, skin injury, and in the development of fibrotic skin diseases. This review provides a detailed overview of the role of the canonical Wnt signaling pathways in regulating skin scarring. We also discuss how Wnt signaling interacts with other known fibrotic molecular pathways to cause skin fibrosis. We further provide a summary of the different Wnt inhibitor types available for treating skin scarring. Understanding the role of the Wnt pathway in cutaneous fibrosis will accelerate the development of effective Wnt modulators for the treatment of skin fibrosis.

Abstract
Fibrosis exists in almost all organs/tissues of the human body, plays an important role in the occurrence and development of diseases and is also a hallmark of the aging process. However, there is no effective prevention or therapeutic method for fibrogenesis. As a serine/threonine (Ser/Thr)-protein kinase, glycogen synthase kinase-3β (GSK-3β) is a vital signaling mediator that participates in a variety of biological events and can inhibit extracellular matrix (ECM) accumulation and the epithelial-mesenchymal transition (EMT) process, thereby exerting its protective role against the fibrosis of various organs/tissues, including the heart, lung, liver, and kidney. Moreover, we further present the upstream regulators and downstream effectors of the GSK-3β pathway during fibrosis and comprehensively summarize the roles of GSK-3β in the regulation of fibrosis and provide several potential targets for research. Collectively, the information reviewed here highlights recent advances vital for experimental research and clinical development, illuminating the possibility of GSK-3β as a novel therapeutic target for the management of tissue fibrosis in the future.

Abstract
The formation of keloid scars is normally induced by cutaneous injuries, however, the detailed mechanisms underlying keloid formation remain largely unknown. The present study aimed to investigate the effects of circular RNA_101238 (circ_101238) on the proliferation and apoptosis of keloid fibroblasts and to identify the underlying molecular mechanisms of these effects. Reverse transcription-quantitative (RT-q)PCR was performed to determine the expression levels of circ_101238, microRNA (miRNA/miR)-138-5p and cyclin-dependent kinase 6 (CDK6) in keloids and normal skin tissues. Following transfection with short hairpin (sh)-circ_101238, LV-circ_101238, miR-138-5p mimics, miR-138-5p inhibitors and small interfering (si)-CDK6, cell proliferation was assessed using a cell counting kit-8 assay. Furthermore, cell apoptosis was evaluated via flow cytometric analysis, while a dual-luciferase assay was performed to confirm interactions between circ_101238, miR-138-5p and CDK6. The expression levels of the proliferation marker, CDK6 and apoptosis marker, caspase-3 were determined via RT-qPCR and western blot analyses. The results demonstrated that expression levels of circ_101238 and CDK6 were significantly increased in keloid samples, while miR-138-5p expression was reduced in comparison to normal skin. Furthermore, circ_101238 was demonstrated to bind miR-138-5p, which subsequently targeted CDK6. Proliferative activity and CDK6 expression were significantly decreased in keloid fibroblasts following transfection with sh-circ_101238 or miR-138-5p mimics, while cell apoptosis was markedly increased. Furthermore, co-transfection with miR-138-5p mimics reversed the effects caused by overexpression of circ_101238. Treatment of keloid fibroblasts with si-CDK6 counteracted the biological behavior changes induced by miR-138-5p inhibitors. Additionally, transfection with LV-CDK6 reversed the effects caused by miR-138-5p mimics. Taken together, the results of the present study demonstrated that circ_101238 was upregulated in keloid tissues in comparison with normal tissues and that circ_101238 knockdown inhibited cell proliferation, while promoting apoptosis of keloid fibroblasts via the miR-138-5p/CDK6 axis. These results suggest that circ_101238 may serve as a promising therapeutic candidate for keloid therapy and that circ_101238/miR-138-5p/CDK6 signaling has the potential to regulate the growth of keloid fibroblasts.

Abstract
To study the effect of knocking down wingless-related MMTV integration site 2 (Wnt2) expression by RNAi on the growth and signaling pathways of ex vitro-cultured keloid fibroblasts (KFB).Human KFB were isolated from 10 keloid patient specimens. The KFB cells were then transfected with 4 pairs of small interfering RNA (siRNA) targeting human Wnt2, respectively. Reverse transcriptase-polymerase chain reaction and Western blot analysis were conducted to verify the knock down of Wnt2, and the expression of β-catenin glycogen synthase kinase-3β (GSK-3β) and cyclin D1 were examined.siRNA Wnt2 transfection (siWnt2) resulted in the significant inhibition of Wnt2 expression at both the mRNA and protein levels. The expression of β-catenin, GSK-3β, p-GSK-3β, and cyclin D1 at the protein level also decreased in siWnt2 cells. siWnt2 resulted in a substantially slower growth and significant delay in cell doubling time of the KFB cells compared with control groups. Further, the siRNA knock down of GSK-3β and β-catenin resulted in slower proliferation rates, respectively.Wnt2 siRNA has an inhibitive effect on keloid fibroblast proliferation, which may be a potential therapeutic approach for keloid and other human fibrotic diseases.

Abstract
The study was aimed to explore the functions of circulating fibrocytes (CFs) on injury repair in acute lung injury/acute respiratory distress syndrome (ALI/ARDS) mice model and its clinical value as a biomarker for ALI/ARDS. ALI/ARDS mice model was established by intratracheal instillation of lipopolysaccharide (LPS). Mononuclear cells were isolated from peripheral blood of ALI/ARDS model and flow cytometry was used to measure CFs defined as cells positive for CD45 and collagen-1. Histological changes of lung tissues were evaluated by H&E staining and Masson's trichrome staining. The correlations of CFs counts with damnification of lung tissue and the severity of pulmonary fibrosis were evaluated by Pearson correlation analyses. Western blot was used to detect the protein expression of collagen-1. ELISA was applied to determine cytokine CXCL12 concentration. Clinical relevance between CFs and ALI/ARDS was investigated. The greater number of CFs in the ALI/ARDS group implied higher degree of lung injury and more severe pulmonary fibrosis. The protein expression of collagen-1 and concentration of cytokine CXCL12 in ALI/ARDS group were higher than that in control group. Clinical and prognostic analysis revealed the higher injury degree and death rates in ALI/ARDS group than those in control group, and identified a greater severity and mortality for patients with ARDS than those with ALI. ROC curve analysis indicated the counts of CFs greater than 5.85% can predict death rates with AUC = 0.928. CFs had an inhibitory effect on injury repair in ALI/ARDS mice model. This might be unfavorable as a clinical marker for progression of ALI/ARDS.

Abstract
The aim of the present study was to detect DACT1 expression levels in the lungs of children with asthma, and to investigate its role and molecular mechanisms in regulating the expression of inflammatory factors in RAW264.7 cells. DACT1, DACT2 and DACT3 expression was analyzed in biopsy specimens from 10 cases of newly diagnosed children with asthma and 10 healthy controls by reverse transcription-quantitative polymerase chain reaction, and their expression was confirmed in RAW264.7 cells. DACT1 expression was silenced by small interfering RNA or enhanced by transfection of pcDNA-3.1-DACT1 in RAW264.7 cells, and expression of β-catenin and inflammatory factors, interleukin (IL) 5, IL6 and IL13, was analyzed. Nuclear translocation of β-catenin was detected by western blot analysis, and the effect of DACT1 on β-catenin was investigated with rescue experiments. Regulation of the Wnt signaling pathway by DACT1 and β-catenin was analyzed in RAW264.7 cells after recombinant Wnt5A stimulation. DACT1, DACT2 and DACT3 were significantly upregulated in specimens from children with asthma compared with controls (P<0.05) and the expression of DACT1 was significantly more increased compared with DACT2 and DACT3 (P<0.05). Inhibition of DACT1 expression significantly suppressed IL5, IL6 and IL13 mRNA expression levels compared with the control (P<0.05), while upregulated DACT1 expression significantly increased IL5, IL6 and IL13 mRNA expression (P<0.05). DACT1 inhibited the expression and nuclear translocation of β-catenin, while overexpression of β-catenin significantly inhibited the biological function of DACT1 (P<0.05). Overexpression of β-catenin also significantly suppressed the upregulation of IL5, IL6 and IL13 mRNA induced by pcDNA3.1-DACT1 transfection (P<0.05). Following the addition of Wnt5A, overexpression of DACT1 inhibited the expression and nuclear translocation of β-catenin, and upregulated IL5, IL6 and IL13 mRNA expression. In conclusion, DACT1 was indicated to be upregulated in lung tissues from children with asthma, which could induce higher pro-inflammatory factor expression. DACT1 may act via inhibiting the expression and nuclear translocation of β-catenin, a factor in the Wnt signaling pathway. The present results suggested that DACT1 may be a potential target for the treatment of asthma.
