RESUMO
ObjectiveTo investigate the difference in bilateral lower limb muscle synergy mode during gait in patients after unilateral anterior cruciate ligament reconstruction. MethodsElectromyography from bilateral lower limb muscles during gait were collected from twelve male and eight female patients after unilateral anterior cruciate ligament reconstruction in Affiliated Hospital of Wuhan Sports University, from April to June, 2023. The data were analyzed using non-negative matrix decomposition algorithm to extract the number of muscle synergies in the affected and unaffected legs, the time to peak activation of muscle synergies and the relative weights of the muscles. ResultsSix types of muscle synergy were identified in the unaffected leg of males during gait, while five types were identified in the affected leg, lacking synergy 2 that mainly from the tibialis anterior muscle. Six types of muscle synergy were identified in both legs in females during gait. There was no significant difference in the time to peak activation of muscle synergies between both legs in males (P > 0.05). However, the time to peak activation of muscle synergies increased in females in the affected leg for synergy 3 and synergy 5 (P < 0.05). The relative weight of the rectus femoris was lower in synergy 1 in the affected leg in males (P < 0.05). For female, the relative weight of the vastus lateralis was higher and the relative weight of the biceps femoris was lower in synergy 2 in the affected leg in females (P < 0.05); while the relative weight of the rectus femoris was lower in synergy 3 (P < 0.05), and the relative weight of the biceps femoris was lower in synergy 6 (P < 0.05). ConclusionMales would freeze the muscle synergy dominating ankle dorsiflexion in affected leg to enhance ankle stability, and reduce the relative weight of rectus femoris during the loading response phase to weaken the knee landing cushioning. However, females would delay the activation of synergies dominating in loading response phase and the mid-stance phase, enhance the relative weight of vastus lateralis during the loading response phase, and reduce the relative weights of rectus femoris in the loading response phase and the relative weight of biceps femoris in the mid-stance phase, to limit knee flexion.
RESUMO
Objective To analyze the relationship between expression level of protein O-fucosyltransferase 1(POFUT1)and tumor immune infiltration level and prognosis of patients,and explore the value of POFUT1 in tumor immunotherapy.Methods Based on the pan-cancer data,R software was used to analyze the changes in POFUT1 expression levels of various tumor tissues and their correlation with the risk ratio of various tumor patients,and screen for tumor types related to patient prognosis and POFUT1 expression.Through the String database,a protein interaction network was constructed,POFUT1-associated genes were screened,and functional enrichment analysis was performed.The estimate software package was used to analyze the correlation between POFUT1 expression and immune infiltration score in selected tumor tissues.The TIMER database was used to analyze the correlation between the expression level of POFUT1 and various levels of immune cell infiltration,and the correlation between the infiltration level of immune cells and the prognosis of patients.Results The expression levels of POFUT1 were significantly high in 14 types of tumors(P<0.05),and were associated with poor prognosis of low-grade gliomas,lung adenocarcinoma,and thyroid cancer(Hazard Ratio>1,P<0.05).POFUT1 and its associated genes were highly involved in Notch signaling pathway,lymphocyte activation and immune regulation processes.The expression level of POFUT1 was positively correlated with the infiltration degree of B cells,CD8+T cells,CD4+T cells,macrophages,neutrophils and dendritic cells in low-grade gliomas,as well as positively associated with the infiltration level of neutrophils in LUAD,and B cells,CD4+ T cells and macrophages in thyroid cancer(|r|>0.2,P<0.05).The high infiltration levels of the above 6 types of immune cells were correlated with the poor prognosis of patients with low-grade glioma(Hazard Ratio>1,P<0.05).Conclusion POFUT1 was highly involved in the process of immune regulation,affecting the immune infiltration level of some tumors and further influencing patient prognosis.It may have the potential to become a target for tumor immunotherapy.
RESUMO
Objective:To construct an artificial intelligence (AI)-assisted system based on deep learning for corneal in vivo confocal microscopy (IVCM) image recognition and to evaluate its value in clinical applications. Methods:A diagnostic study was conducted.A total of 18 860 corneal images were collected from 331 subjects who underwent IVCM examination at Renmin Hospital of Wuhan University and Zhongnan Hospital of Wuhan University from May 2021 to September 2022.The collected images were used for model training and testing after being reviewed and classified by corneal experts.The model design included a low-quality image filtering model, a corneal image diagnosis model, and a 4-layer identification model for corneal epithelium, Bowman membrane, stroma, and endothelium, to initially determine normal and abnormal corneal images and corresponding corneal layers.A human-machine competition was conducted with another 360 database-independent IVCM images to compare the accuracy and time spent on image recognition by three senior ophthalmologists and the AI system.In addition, 8 trainees without IVCM training and with less than three years of clinical experience were selected to recognize the same 360 images without and with model assistance to analyze the effectiveness of model assistance.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2021-K148).Results:The accuracy of this diagnostic model in screening high-quality images was 0.954.Its overall accuracy in identifying normal/abnormal corneal images was 0.916 and 0.896 in the internal and external test sets, respectively.Its accuracy reached 0.983, 0.925 in the internal test sets and 0.988, 0.929 in the external test sets in identifying corneal layers of normal and abnormal images, respectively.In the human-machine competition, the overall recognition accuracy of the model was 0.878, which was similar to the average accuracy of the three senior physicians and was approximately 300 times faster than the experts in recognition speed.Trainees assisted by the system achieved an accuracy of 0.816±0.043 in identifying corneal layers of normal and abnormal images, which was significantly higher than 0.669±0.061 without model assistance ( t=6.304, P<0.001). Conclusions:A deep learning-based assistant system for corneal IVCM image recognition is successfully constructed.This system can discriminate normal/abnormal corneal images and diagnose the corresponding corneal layer of the images, which can improve the efficiency of clinical diagnosis and assist doctors in training and learning.
RESUMO
Objective:To investigate the role of microRNA (miR)-497 in the formation of corneal neovascularization (CNV) induced by alkali burn and its mechanism.Methods:Forty-two wild type (WT) C57BL/6 mice aged 6 to 8 weeks, 42 CRISPR/Cas9 mediated miR-497 knockout (KO) and 42 CRISPR/Cas9 mediated overexpression transgenic (TG) C57BL/6 mice were selected and assigned as WT group, KO group and TG group, respectively.The corneal alkali burn model was established.At 3, 7, 14 and 21 days after modeling, corneal epithelium damage and stromal turbidity were scored according to slit lamp microscopy.The area of neovascularization was measured.Corneal structural changes and expression of inflammatory cells were observed by histopathological staining.The expression of CD31 in corneal tissues was detected by immunohistochemistry staining.The targeted binding relationship between miR-497 and signal transducer and activator of transcription 3 (STAT3) was detected by luciferase reporter assay.The relative expressions of miR-497, vascular endothelial growth factor A (VEGFA), tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β and macrophage inflammatory protein (MCP)-1 mRNA were detected by real-time quantitative PCR.At 14 days following modeling, the expression of STAT3 and p-STAT3 proteins in mice corneal tissues was detected by Western blot.The use and care of animals complied with the ARVO statement.The study protocol was approved by the Ethics Committee of Renmin Hospital of Wuhan University (No.2019K-K010).Results:Corneal injury, inflammatory cell infiltration and CNV occurred in mice cornea after alkali burn.Corneal epithelial injury score, corneal stromal turbidity score and CNV area increased first and reached the peak on the 14th day after modeling, and then decreased.There were significant differences in corneal epithelial injury score, corneal stromal turbidity score, CNV area and number of CD31-positive cells among various time points after alkali burn ( Fgroup=49.19, 34.56, 44.56, 77.56; all at P<0.01; Ftime=51.62, 65.62, 71.32, 46.12; all at P<0.01). Corneal epithelial injury score, corneal stromal turbidity score, CNV area and the number of CD31-positive cells were greater in KO group at various time points than in WT and TG groups, and those in WT group were greater than in TG group (all at P<0.05). In WT STAT3 co-transfected cells, the luciferase activity of the miR-497 group was significantly lower than that of the miR-negative control group and normal control group (both at P<0.05). In mutant STAT3-transfected cells, there was no significant difference in luciferase activity among all groups ( F=0.69, P=0.56). On the 14th day after modeling, the relative expression levels of miR-497 in corneal tissue of WT, KO and TG groups were 0.68±0.11, 0.41±0.06 and 1.05±0.14, respectively, which were significantly lower than 1.00±0.04, 0.56±0.07 and 1.34±0.11 before modeling (all at P<0.01). The relative expressions of STAT3 and p-STAT3 were higher in KO group than in WT and TG groups, and were lower in TG group than in WT group, and the differences were statistically significant (all at P<0.05). The expressions of VEGFA, TNF-α, IL-6, IL-1β and MCP-1 mRNA at various time points after modeling in various groups were significantly higher than before modeling, which were higher in KO group than in WT and TG groups and were lower in TG group than in WT group, and the differences were statistically significant (all at P<0.01). Conclusions:MiR-497 inhibits corneal inflammation and CNV formation induced by alkali burn.It might inhibit the activation of the inflammation signal pathway via targeting STAT3.

RESUMO
OBJECTIVE@#To study the value of plasma miRNA23-a and miRNA-451 as potential biomarkers for early diagnosis of non-small cell lung cancer (NSCLC).@*METHODS@#Fifty patients with NSCLC and 50 healthy control subjects were recruited for testing the plasma levels of miRNA23-a and miRNA-451 and their expression levels in the tumor tissues using qRT-PCR. The correlations of the plasma levels of miRNA23-a and miRNA-451 with their expressions in the tumor tissues were analyzed. The diagnostic power of CEA, miRNA23-a and miRNA-451 for NSCLC was evaluated using the receiver-operating characteristics (ROC) curves and the area under the ROC curves (AUC). In the NSCLC cell line A549, we tested the effect of inhibition of miRNA-23a and miRNA-451 on the expression levels of SPRY2 and MIF mRNA using qRT-PCR.@*RESULTS@#The expression levels of miRNA-23a and miRNA-451 in NSCLC tissues was significantly associated with smoking, tumor size, lymph node metastasis and TNM stage ( < 0.05). Compared with those in the control group, miRNA-23a level was significantly increased while miRNA-451 was significantly down-regulated in the tumor tissues and plasma of NSCLC patients. The plasma levels of miRNA-23a and miRNA-45 were strongly correlated with their expression levels in the tumor tissues. ROC analysis showed that for the diagnosis of NSCLC, the AUC, sensitivity and specificity of either miRNA-23a or miRNA-451 were significantly higher than those of CEA ( < 0.05). The combination of miRNA23-a and miRNA-451 markedly improved the AUC (0.900), sensitivity (78%) and specificity (86%) for the diagnosis. In A549 cells, inhibition of miRNA23-a and miRNA-451 resulted in significantly increased expression levels of SPRY2 mRNA and MIF mRNA, respectively.@*CONCLUSIONS@#miRNA-23a and miRNA-451 can be used as potential biomarkers for early diagnosis of NSCLC, and their combined detection can be more effective for the diagnosis.
