Arch Med Sci 2022; 18:36-44. [PMID: 35154523 PMCID: PMC8826683 DOI: 10.5114/aoms/98948] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Accepted: 10/14/2018] [Indexed: 12/16/2022] Open
Abstract
INTRODUCTION Previous studies have hypothesized fibroblast growth factor 21 (FGF-21) as a potential biomarker of the inflammation associated with liver diseases, which is also receiving considerable attention for its potential application concerning the management of obesity and co-morbidities. This study aimed to analyze the response of FGF-21 after a weight loss intervention and the relationships with other putative inflammatory liver biomarkers. MATERIAL AND METHODS Sixty-six obese participants from the RESMENA study were evaluated at baseline and following a 6-month energy restriction treatment. Anthropometric, body composition by DXA, routine laboratory measurements, which included transaminases and γ-glutamyl transferase (GGT) were analyzed by standardized methods. Moreover, FGF-21, M30 fragment (M30) and plasminogen activator inhibitor-1 (PAI-I) were analyzed as recognized liver inflammatory related biomarkers with specific ELISA kits. RESULTS Most measurements related to hepatic damage, inflammation and adiposity status improved at the end of the 6-month nutritional intervention. In addition, ΔFGF-21 shifts showed statistical relationships with changes in ΔM30, ΔGGT and ΔPAI. The reduction of M30 showed significant associations with changes in transaminases. Furthermore, PAI-I changes were associated with ΔM30 and ΔGGT regardless of weight loss. A linear regression model was set up to assess the influence of ΔPAI-I and ΔM30 on the variability of ΔFGF-21 (23.8%) adjusted by weight loss. CONCLUSIONS These results demonstrated interactions of some liver inflammatory mediators, specifically M30 and PAI-I with FGF-21. Thus, more investigation about FGF-21 is required given that this protein could be a biomarker of the obesity-inflammation-liver process.

Abstract
INTRODUCTION Postoperative peritoneal adhesion is an important complication of abdominopelvic surgery. The aim of this study is to reveal the effect of platelet-rich plasma (PRP) on postoperative intraperitoneal inflammation and adhesions. MATERIAL AND METHODS Twenty-four Wistar albino rats were divided into three groups. Cecal incision and suturation was carried out for the experimental model. Intraperitoneally, 3 ml of 0.9% NaCl, 3 ml of PRP, and nothing were applied, and called as saline, PRP, and control groups, respectively. Four subjects in each group were sacrificed at the 3rd and 7th days postoperatively. Adhesion formations and giant cell, lymphocyte/plasmocyte, neutrophil, and histiocyte counts were assessed and hydroxyproline levels were measured in all groups and statistical comparisons were performed. RESULTS Except giant cell 3rd day scores, PRP had the lowest adhesion, neutrophil, lymphocyte, plasmocyte, histiocyte and fibrosis scores. Both 3rd and 7th days scores of giant cell, neutrophil, lymphocyte, plasmocyte, but only 7th days scores of histiocyte reaction and fibrosis were statistically significant (p < 0.05). Hydroxyproline levels were lower in the saline group at the 3rd day. However, at the 7th day, the levels were lower in the PRP group and no statistically significant difference was found compared to the saline group 3rd day levels (p > 0.05). CONCLUSIONS Platelet-rich plasma has a reducing effect on the postoperative peritoneal adhesions with separation of the damaged tissues, affecting the inflammation, matrix metalloproteinase, plasminogen activation or the other stages of adhesion formation.

Abstract
INTRODUCTION MicroRNAs (miRNAs) are endogenous small noncoding RNA molecules involved in modulation of cancer progression. Here, we investigated the possible role of miR-144 in non-small cell lung cancer (NSCLC) development. MATERIAL AND METHODS The expression of miR-144 and TLR2 in NSCLC tissue and cell lines was determined by quantitative real-time PCR (qPCR). The TargetScan database was used to predict potential target genes of miR-144. Luciferase assay was used to verify the interaction between TLR2 and miR-144. TLR2 protein expression was measured by western blot. The secretion of interleukin (IL)-1β, IL-6 and IL-8 in A549 cells was detected by an ELISA kit. Cell migration and invasion were evaluated by wound healing assay and transwell assay, respectively. RESULTS Our results showed that miR-144 was downregulated in NSCLC tissue and cell lines when compared with the normal tissues and cell line (p < 0.05). The protein level of TLR2 in NSCLC tissue and cell lines was significantly higher than that in normal lung tissues. Dual luciferase reporter gene assay showed that miR-144 could bind to the 3'UTR of TLR2 specifically. Up-regulation of miR-144 significantly decreased the expression of TLR2. Up-regulation of miR-144 or down-regulation of TLR2 could decrease cell migration, invasion and secretion of IL-1β, IL-6 and IL-8 in A549 cells. Moreover, overexpression of TLR2 rescued the inhibitory effects of miR-144 on migration, invasion and inflammatory factor secretion of A549 cells. CONCLUSIONS miR-144 could inhibit the migration, invasion and secretion of IL-1β, IL-6 and IL-8 through downregulation of TLR2 expression in A549 cells.

Abstract
Introduction Chronic heart failure (CHF) is a leading cause of deaths induced by cardiovascular disease. This study aimed to investigate the protective effects of emodin in CHF rats and explore the related mechanisms. Material and methods A total of 56 Wistar rats were used to construct CHF model using the coronary artery ligation. The effects of emodin on cardiac function and inflammation were analyzed in the CHF rats. Expression of miR-26b-5p in the CHF model before and after emodin treatment was estimated by quantitative real-time polymerase chain reaction. The effects of miR-26b-5p on cardiac function and inflammation were also assessed, and its target gene was predicted and confirmed in rat cardiomyocyte H9c2. Results Emodin treatment could significant improve the cardiac function and inflammation evidenced by the increased increased ejection fraction (EF), fractional shortening (FS), left ventricular systolic pressure (LVSP) and maximum of the first differentiation of left ventricular pressure (+LV dP/dtmax) and decreased atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), left ventricular end diastolic pressure (LVEDP), interleukin (IL)-6, tumor necrosis factor α (TNF-α) levels. Expression of miR-26b-5p was downregulated in the CHF rats (CHF 0.442 ±0.131 vs. Sham 1.044 ±0.160), and this suppressive effect was rescued by emodin (Emodin 0.902 ±0.132 vs. CHF 0.442 ±0.131). The overexpression of miR-26b-5p in CHF rats led to improved cardiac function and inflammatory response. In addition, the emodin-induced increased EF, FS, LVSP and +LV dP/dtmax and decreased ANP, BNP, LVEDP, IL-6 and TNF-α were all abrogated by the knockdown of miR-26b-5p. The target prediction results revealed that PTEN was a target gene of miR-26b-5p in H9c2 cells. Conclusions All the results indicated that emodin serves a protective role in CHF via regulation of the miR-26b-5p/PTEN pathway. Emodin may be an effective therapeutic agent for CHF treatment.

Abstract
ZnO-based nanomaterials are a subject of increasing interest within current research, because of their multifunctional properties, such as piezoelectricity, semi-conductivity, ultraviolet absorption, optical transparency, and photoluminescence, as well as their low toxicity, biodegradability, low cost, and versatility in achieving diverse shapes. Among the numerous fields of application, the use of nanostructured ZnO is increasingly widespread also in the biomedical and healthcare sectors, thanks to its antiseptic and antibacterial properties, role as a promoter in tissue regeneration, selectivity for specific cell lines, and drug delivery function, as well as its electrochemical and optical properties, which make it a good candidate for biomedical applications. Because of its growing use, understanding the toxicity of ZnO nanomaterials and their interaction with biological systems is crucial for manufacturing relevant engineering materials. In the last few years, ZnO nanostructures were also used to functionalize polymer matrices to produce hybrid composite materials with new properties. Among the numerous manufacturing methods, electrospinning is becoming a mainstream technique for the production of scaffolds and mats made of polymeric and metal-oxide nanofibers. In this review, we focus on toxicological aspects and recent developments in the use of ZnO-based nanomaterials for biomedical, healthcare, and sustainability applications, either alone or loaded inside polymeric matrices to make electrospun composite nanomaterials. Bibliographic data were compared and analyzed with the aim of giving homogeneity to the results and highlighting reference trends useful for obtaining a fresh perspective about the toxicity of ZnO nanostructures and their underlying mechanisms for the materials and engineering community.

Abstract
BACKGROUND p300, a transcription co-activator, plays an important role in multicellular organisms and inflammation. However, the mechanism of p300 in type 2 diabetes nephropathy (T2DN) remains largely unknown. Our aim is to explore the mechanism of p300 in T2DN. METHODS A T2DN mice model was induced by db/db transgenic mice or a high fat diet for 24 weeks. The levels of IL-6 and TNF-α were examined by real-time PCR (RT-PCR) in the renal cortex and by an enzyme linked immunosorbent assay (ELISA) in the serum of the T2DN mice. p300 siRNA was used to knockdown the expression of p300, and His-tagged-p300 plasmid was used to overexpress the p300 protein level in podocytes. Hematoxylin-eosin staining (H&E) and Masson trichrome analysis were used to detect the kidney pathology in T2DN. RESULTS The levels of IL-6 and TNF-α were significantly increased in T2DN. p300 was significantly increased in T2DN. Consistently, p300 silencing significantly suppressed the inflammatory response and the overexpression of p300 significantly promoted the production of IL-6 and TNF-α in T2DN. CONCLUSIONS This study demonstrated that the production of IL-6 and TNF-α, and the expression of p300, were increased in T2DN. Furthermore, P300 significantly promoted the activation of the NF-κB subunit p65 through a direct association with p65 in T2DN, subsequently enhancing the production of IL-6 and TNF-α.

Autogenously derived regenerative cell therapy for venous leg ulcers. ACTA ACUST UNITED AC 2018; 3:e156-e163. [PMID: 30775606 PMCID: PMC6374579 DOI: 10.5114/amsad.2018.81000] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2018] [Accepted: 10/09/2018] [Indexed: 12/23/2022]
Abstract
Introduction Venous leg ulcers (VLUs), which arise from chronic venous insufficiency in the lower limbs, are a major cause of morbidity and significantly negatively impact patients’ health-related quality of life. Treatment of venous ulcers can be either conservative or surgical. Despite appropriate treatment, VLUs can be resistant to healing. Clinical results of treatment of venous foot ulcers with adipose-derived autologous stem cells, which did not improve despite the surgical treatment of the underlying venous pathology in the following case series, are reported. Material and methods Between April 2015 and January 2016, a total of 31 patients who had undergone surgery for underlying venous pathology but the venous ulcer had not healed were included in the study. The mean venous ulcer size was 3.6–6.2 cm (range: 2 to 8 cm by 3 to 9 cm). All patients were treated with adipose-derived autologous stem cells prepared using the MyStem Regenerative Adipose-Derived Stem Cell Purification Kit (MyStem LLC, USA). The ulcer diameter was measured and recorded in the third, sixth and twelfth months. The follow-up time was 12 months after ulcer healing. Results Eighteen ulcers demonstrated complete healing at the 12th month. Thirteen ulcers exhibited serious contraction and epithelialization even though the ulcer was not completely closed. At the 12th month, the ulcer size was reduced by 96.00 ±1.74% in these patients. The reduction in the ulcer area based on the month analyzed was significant (p = 0.001; p < 0.01). After the ulcers healed, the patients were followed for recurrence for one year. Recurrent ulcers were observed at the treated sites in 3 of 31 patients (9%). No adverse events, such as infection, inflammation, or tissue reactions, were observed. Conclusions Application of cell therapy in venous leg ulcer is currently used exclusively in patients not responding to the standard treatment. Autogenously derived regenerative cell therapy for VLUs can be considered as an additional treatment to primary surgical therapy.
