Impaired wound healing is associated with hyperglycaemia in patients with diabetes. Hyperglycaemia induces protein glycation and the formation of Advanced Glycation End-Products (AGEs). The accumulation of AGEs in the body results in the structural and functional modification of tissue proteins. This study was conducted to evaluate compounds with antiglycation activities (S-Ally1 Cysteine (SAC), N-Acetylcysteine (NAC) and the mimic compound A). The extent of glycation in the presence and absence of several inhibitors was assessed via several methods including fluorescence, Sodium Dodecyl Sulphate-Polyacrylamide Gel Electrophoresis (SDS-PAGE)- silver stain, Western blotting, and Enzyme-Linked Immunosorbent Assays (ELISA). Additionally, this research aimed to evaluate and quantify the potential of Human Adipose Mesenchymal Stem Cells (hADMSCs) to uptake and release these drugs as potential therapeutics. To achieve this, hADMSCs were primed with a combination of SAC/NAC and mimic compound A and their concentrations were analysed using High-Performance Liquid Chromatography (HPLC). The SAC/NAC and mimic compound A prohibit the formation of AGEs while the Conditioned Medium (CM) from SAC/NACand compound A-loaded hADMSCs induced cell migration and tube formation in BAECs. hADMSCs provide a unique opportunity for the development of an innovative targeting and drug-delivery system which could effectively deliver therapeutics to specific regions of wounds or other damaged tissues. The data provided demonstrate the potential of hADMSCs as a drug delivery method with the potential to improve wound healing, and it may offer potential therapeutic targeting for the development of diabetic complications.
Advanced Glycation End-Products (AGEs) have been implicated in the chronic complications of Diabetes Mellitus (DM) and play an important role in the pathogenesis of atherosclerosis in human arteries. The main active compounds found in Aged Garlic Extract (AGExt) are S-Allyl Cysteine (SAC), N-Acetylcysteine (NAC) and S-allyl Mercaptocysteine (SAMC) and have powerful protective effects against oxidative stress and inhibit cellular damage by AGEs. Aims: To explore the effect of AGExt on the development of atherosclerosis also investigated the endothelial protective effects of AGExt, using Human Coronary Artery-Derived Endothelial Cells (HCAEC). The use of an optimised mixture of the above compounds required to obtain and provide maximal beneficial effects against oxidative stress, cell apoptosis and protein glycation. Results: AGExt has protective effects against the cellular damage of HCAEC. In addition, the in vivo study accessed the activity of SAC and NAC to reduce the severity of atherosclerosis formation in Apolipoprotein (ApoE-/-) DM model mouse. The compounds of AGExt in vitro had strong protective actions against the AGEs induced damage to ECs even at low concentrations (100 ng/ml). Such low concentrations may have therapeutic usefulness in patients with diabetes.
AIM:To explore the clinical value of magnetic resonance imaging (MRI) combined with serum prostate specific antigen (PSA), epithelial cadherin (sE-cadherin) and early prostate cancer antigen-2 (EPCA-2) in prostate cancer (PC) diagnosis.PATIENTS AND METHODS:Fifty patients with PC and 50 with benign prostatic hyperplasia (BPH) confirmed by pathology from January 2020 to July 2021 were studied retrospectively. All patients underwent MRI and measurement of the serum levels of PSA, EPCA-2, and sE-cadherin. The diagnostic accuracy and efficacy of these methods was compared between the groups.RESULTS:In MRI diagnosis of PC, lesions were mainly located in the peripheral zone; T2-weighted imaging of this zone showed low signal intensity, with different degrees of prostate enlargement. BPH had a clear boundary, complete capsule and central zone hyperplasia and uneven signal nodules. PC and BPH had different degrees of prostate enlargement. Serum levels of PSA, sE-cadherin and EPCA-2 in the cancer group were significantly higher than those in the BPH group (p<0.05). The diagnostic concordance of combined assessment of MRI, PSA, sE-cadherin, and EPCA-2 in differentiating PC from BPH was 93%, which was significantly higher than these approaches used alone (84%, 79%, 81% and 82%, respectively; p<0.05). The area under the receiver operating characteristics curve for the combined approach in PC diagnosis was 0.900, which was significantly higher than those for the individual methods (0.840, 0.730, 0.760 and 0.810, respectively; Z=2.343, p=0.004).CONCLUSION:MRI combined with PSA, sE-cadherin and EPCA-2 can improve the sensitivity and accuracy of PC diagnosis and has potential as a guiding scheme for early diagnosis of PC.

Circular RNAs (circRNAs) and microRNAs (miRNAs) have been emerging as new players in acute myeloid leukemia (AML). Hsa_circ_0005774 (circ_0005774) is an upregulated circRNA in pediatric AML, while its role is uncovered. Thus, we intended to measure the function and mechanism of circ_0005774 in AML leukemogenesis. Real time-quantitative PCR revealed that circ_0005774 was highly expressed in blood of pediatric AML patients and AML cells (HL-60 and NB4), accompanied with downregulated miRNA-192–5p (miR-192–5p) which was a crucial tumor-associated and leukemia-related miRNA. Circ_0005774 was abundant in miRNA response element according to CSCD software, and miR-192–5p was identified as a target of circ_0005774, as evidenced by RNA immunoprecipitation and dual-luciferase reporter assays. Cell viability assay, flow cytometry and western blotting were performed to measure cell functions. Accordingly, blocking circ_0005774 and/or overexpressing miR-192–5p could enhance apoptosis rate of HL-60 and NB4 cells, but suppress cell viability and cell cycle entrance, accompanied with depression of proliferation markers including proliferating cell nuclear antigen (PCNA), CyclinD1 and B cell lymphoma 2 (Bcl-2). Meanwhile, depleting miR-192–5p counteracted the role of circ_0005774 knockdown in AML cells. Uncoordinated 51-like kinase 1 (ULK1) was previously demonstrated to be associated with diagnosis, prognosis and therapeutic strategy for AML, and restoring ULK1 could abrogate miR-192–5p overexpression-induced effects in HL-60 and NB4 cells. Notably, ULK1 was a downstream target of miR-192–5p and indirectly modulated by circ_0005774. In conclusion, circ_0005774 knockdown repressed cell proliferation and promoted apoptosis of AML cells partially through regulating miR-192–5p/ULK1 axis.

However, the role of miR4284 in non-small cell lung cancer (NSCLC) is largely unknown. The aim of this study was to investigate the expression and biological role of miR-4284 in NSCLC. Patients and Methods: The qRT-PCR assay was applied to detect the expression of miR4284 in NSCLC tissues and cell lines. Kaplan–Meier curve method and multiple Cox regression analyses were used to explore the prognostic factors for postoperative NSCLC patients. The CCK-8 assay was carried out to measure the proliferative abilities of A549 and H1299 cells. Transwell migration and invasion assays were used to determine the cell migratory and invasive capabilities of NSCLC cells. Results: miR-4284 expression was upregulated in NSCLC tissues and cell lines. High expression of miR-4284 was correlated with poor differentiation, positive lymph node metastasis, and advanced TNM stages. In addition, postoperative patients with higher expression of miR-4284 exhibited a shorter overall survival time than those with lower expression of miR-4284. Moreover, the upregulation of miR-4284 accelerated cell proliferative, migratory, and invasive abilities of A549 and H1299 cells, while the downregulation of miR-4284 inhibited these cellular capabilities. Conclusion: miR-4284 was noticeably upregulated in NSCLC and associated with a poor prognosis of postoperative NSCLC patients. miR-4284 promoted the proliferation, migration, and invasion of A549 and H1299 cells. This study indicated that miR-4284 might serve as a prognostic biomarker and a potential therapeutic target for postoperative NSCLC patients.

Objective To investigate the cognitive impairment and risk factors in patients with systemic lupus erythematosus (SLE). Methods 65 patients with systemic lupus erythematosus were diagnosed in the Affiliated Hospital of Weifang Medical College, from January 2015 to January 2019, including 12 males and 53 females, with an average age of (32.5±13.5) years and an average length of education of (13.6±5.4) years. Sixty-five patients with non-systemic lupus erythematosus hospitalized in our hospital during the same period were selected as control group, 12 males. Fifty-three women, with an average age of (35.5+15.5) years and an average length of education of (12.5+6.5) years, were assessed by Montreal Cognitive Function Scale (MoCA) and their risk factors were analyzed by Logistic. Results Among 65 SLE patients, 32 (49.23%) had cognitive impairment, which was significantly higher than 15 (23.08%) in the control group.Compared with the MoCA scale of the control group, the scores of visual space and executive ability, naming, attention, abstraction, delayed recall, orientation and total score of SLE group were significantly lower than those of the control group. Logistic analysis showed that the course of disease was long (OR 2.01, 95% CI 1.52-5.84), combined with nervous system damage (OR 5.92, 95% CI 1.56-8.34), kidney disease (OR 3.45, 95% CI 1.34-4.72), hematological complications (OR 3.73%, 95% CI 1.05-5.68), and side effects of drugs were significant (OR 2.92, 95% CI 1.56-8.34), and hematological complications (OR 3.73%, 95% CI 1.05-5.68), insufficient social security (OR 1.45, 95% CI 1.04-4.72), and long time to achieve clinical remission (OR 2.73, 95% CI 1.05-3.68) are independent risk factors for cognitive impairment in SLE patients. Conclusion Systemic lupus erythematosus patients with high incidence of cognitive impairment, long course of disease, combined with nervous system damage, kidney disease, blood system complications, significant side effects of drugs, inadequate social security, long time to achieve clinical remission are independent risk factors for cognitive impairment of systemic lupus erythematosus.
In this study, the protective effect of valsartan against glycerol-induced acute kidney injury (AKI) in male albino rats was investigated. Valsartan is used to treat high blood pressure and congestive heart failure and can prolong lifespan following a heart attack. The rats were divided into control, AKI, AKI + valsartan 100 mg/kg bw, and AKI + valsartan 200 mg/kg bw groups. Superoxide dismutase, glutathione peroxidase, catalase, lipid peroxidation, and reduced glutathione were assessed, and histopathological, immunohistochemical and western blot analyses were performed. Valsartan supplementation in AKI rats substantially increased superoxide dismutase, catalase, glutathione peroxidase, and glutathione levels but reduced the level of lipid peroxidation. Valsartan significantly reduced the severity of the renal tubular injury, renal lesions, and necrosis. Valsartan decreased NF-κB and TLR4 mRNA expression by >50% and their protein levels by >40%. Therefore, valsartan supplementation inhibited glycerol-induced functional and pathological damage to the kidney in a concentration-dependent manner. We propose that valsartan protects rat kidney tissue by downregulating NF-κB and TLR4 expression.
The aim of this study was to explore the correlation of salazosulfamide efficacy on ankylosing spondylitis and N-acetyltransferase 1 (NAT1) gene polymorphism. Thirty-two patients with ankylosing spondylitis were recruited in the experimental group and 36 normal individuals were recruited to the control group. The experimental group received 8.0 mg of salazosulfamide (MTX) per week and the control group received isodose of normal saline. Twenty-six patients in the experimental group responded to the salazosulfamide treatment and 6 did not show response. Morning stiffness time of patients in the experimental group who responded to salazosulfamide was significantly lower than that of patients with no reaction to salazosulfamide, and similar to patients in the control group. The average tender joint count of patients in the experimental group that responded to salazosulfamide was lower than in patients with no response to treatment, and similar to patients in the control group. NAT1 gene sequencing determined that the patients sensitive to salazosulfamide treatment manifested as AA/AG at 263 locus, whereas patients not sensitive to salazosulfamide were GG. NAT1 expression was comparable between the different genotypes at the mRNA level. However, there was a significant difference of NAT1 protein between groups. Overall, salazosulfamide demonstrates curative activity for ankylosing spondylitis and we believe that NAT1 AA/GG genotype at 263 locus can promote salazosulfamide effectiveness on ankylosing spondylitis.
