Abstract Background This study aimed to explore the effect of serum miR-101-3p combined with pepsinogen (PG) on early diagnosis of gastric cancer (GC).Methods The peripheral blood was isolated from patients with atrophic gastritis (AG), GC and healthy individuals respectively. RT-qPCR was used to detect the expression of miR-101-3p. Electrochemiluminescence (ECL) was used to reveal the carcinoembryonic antigen (CEA) expression level. Moreover, the expression of PGI and PGII was detected by ELISA. Furthermore, the area under the receiver operating characteristic (ROC) curve (AUC) was used to analyze the diagnostic efficacy of miR-101-3p and PG in early GC patients, AG patients and healthy individuals.Results There were significant differences in the expression levels of miR-101-3p, PGI and PGI/II ratio among groups (all P < 0.05). Serum miR-101-3p expression was correlated with process of invasion (P = 0.03). The miR-101-3p + PGI/II and miR-101-3p + PGI + PGI/PGII have higher diagnostic value (AUC) in AG (all P < 0.05). Meanwhile, miR-101-3p + PGI, miR-101-3p + PGI/II and miR-101-3p + PGI + PGI/II have higher AUC in GC (all P < 0.05). Moreover, miR-101-3p + PGI + PGI/II significantly (P < 0.05) improved the value of each indicator in individual diagnosis (sensitivity: 80.23, specificity: 77.05)Conclusions The miR-101-3p might take part in the progression of GC via influencing cell invasion. Furthermore, miR-101-3p + PG might be used as a novel marker for clinical diagnosis of GC.

Abstract Background This study aimed to investigate the effect of combination of plasma miR-181b, miR-196a and miR-210 on early diagnosis of pancreatic cancer (PC).Methods In our study, the plasma was isolated from patients with PC and healthy individuals, respectively. The expressions of miR-181b, miR-196a and miR-210 were detected by qRT-PCR. Moreover, the level of carbohydrate antigen 199 (CA199) was measured by electrochemiluminescence (ECL) assay. Furthermore, the area under the receiver operating characteristic (ROC) curve (AUC) was used to analyze the diagnostic efficacy of miR-181b, miR-196a, miR-210 and CA199, as well as the combination of thses miRNAs in early PC patients and healthy individuals.Results The expressions of miR-181b, miR-196a and miR-210 were significantly upregulated in PC patients. In addition, the level of CA199 was also significantly upregulated in the plasma of PC patients. The expressions of miR-181b, miR-196a and miR-210 were closely associated with lymph nodes metastasis, clinical stage and vascular invasion, but had no correlation with the patient's age, gender and tumor size. Moreover, miR-181b, miR-196a and miR-210 have lower AUC than CA199 in PC patients. The combinations miR-181b + miR-196a, miR-181b + miR-210, miR-196a + miR-210 also have lower AUC than CA199 in PC patients. It is worth noting that the combinations miR-181b + miR-196a + miR-210 have higher AUC than CA199 in PC.Conclusions Our study demonstrated that the combination of plasma miR-181b, miR-196a and miR-210 had good value for PC early diagnosis.

Abstract Background: This study aimed to explore the diagnostic value of serum miR-101-3p combined with pepsinogen (PG) on early diagnosis of gastric cancer (GC). Methods: A total of 61 atrophic gastritis (AG) and 86 GC patients, and 50 healthy volunteers were enrolled. The serum expression of miR-101-3p was measured by qRT-PCR. The serum content of carcinoembryonic antigen (CEA) was measured by Electrochemiluminescence immunoassay. The serum contents of PGI and PGII were measured by Enzyme linked immunosorbent assay. The diagnostic value of serum markers on AG and GC was analyzed by receiver operating characteristic (ROC) analysis. Results: The expression of miR-101-3p, the content of PGI and the ratio of PGI/II were significantly decreased, and the content of PGII was significantly increased in AG patients compared with those in normal controls. The changes of the above serum indicators were more obvious in GC patients than those in AG patients. The content of CEA was significantly higher in GC patients than that in AG patients. In addition, the expression of miR-101-3p was negatively associated with the submucosal infiltration in GC patients. MiR-101-3p exhibited high diagnostic value on AG (AUC 0.8493, sensitivity 80.33%, specificity 80%) and GC (AUC 0.8749, sensitivity 72.09%, specificity 86.49%). MiR-101-3p + PGI + PGI/II (AUC 0.856, sensitivity 80.23%, specificity 77.05%) exhibited a high diagnostic value in distinguishing between AG and GC. Conclusions: MiR-101-3p was a potential diagnostic marker for AG and GC. MiR-101-3p + PGI + PGI/II was effective in distinguishing between AG and GC.

Background. Gastric cancer (GC) has a poor prognosis due to the lack of ideal tumor markers. Circular RNAs (circRNAs) are a novel type of noncoding RNA related to the occurrence of GC. Among our research, we investigated the role of hsa_circ_0005556 in GC. Materials and Methods. The expression of hsa_circ_0005556 of 100 paired GC tissues and adjacent normal tissues was detected using quantitative reverse transcription-polymerase chain reaction (qRT-PCR). A receiver operating characteristic (ROC) curve was established to evaluate the diagnostic value of hsa_circ_0005556. The correlation between the expression of hsa_circ_0005556 and corresponding clinicopathological characteristic was explored. Results. hsa_circ_0005556 was significantly downregulated in GC tissues contrasted with adjacent normal tissues (n=100, p<0.001). The areas under the ROC curve (AUC) of hsa_circ_0005556 were up to 0.773, while 64% sensitivity and 82% specificity, respectively. Moreover, its expression levels were significantly associated with differentiation (p=0.001), TNM stage (p=0.013), and lymphatic metastasis (p=0.039). GC patients of high hsa_circ_0005556 levels had a longer overall survival (OS) than those of the low group (p=0.047). Conclusion. hsa_circ_0005556 is a potential biomarker for GC, which may guide judgment of the indication of endoscopic treatment for early gastric cancer (EGC).

Abstract Background: This study aimed to examine the expression of serum miR-378 in prostate cancer (PCa) patients and healthy individuals and to identify the value of miR-378 in PCa diagnosis.Methods: The expression of serum miR-378 between groups was compared by t-test. The association between miR-378 expression and clinical characteristics of PCa patients was assessed using Chi-square test. The diagnostic value of serum miR-378 in PCa was estimated by the receiver operating characteristic (ROC) analysis.Results: The expression level of serum miR-378 in PCa patients was significantly lower than that in healthy individuals (P<0.0001). MiR-378 expression was affected by positive AR (P=0.004), large Gleason score (P=0.013) and advanced TNM stage (P=0.020), however, it had no relationship with age, serum PSA, NED rate and urine retention (all, P>0.05). The ROC curve showed that the optimal cutoff value was 1.845, giving the sensitivity and specificity of 75.21% and 89.77%, respectively. Besides, the area under the ROC curve (AUC) was 0.894, indicating serum miR-378 was of great diagnostic value in screening PCa patients from healthy controls (P<0.0001, 95%CI =0.852-0.936).Conclusions: Taken together, the increased expression of serum miR-378 might act as a potential biomarker for PCa diagnosis.

Background: The coronavirus disease 2019 (COVID-19) outbreak, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been declared a global pandemic. It is well-established that SARS-CoV-2 infection can lead to dysregulated immune responses. Arginase-1 (Arg1), which has a pivotal role in immune cells, can be expressed in most of the myeloid cells, e.g., neutrophils and macrophages. Arg1 has been associated with the suppression of antiviral immune responses. Methods: Whole blood was taken from 21 COVID-19 patients and 21 healthy individuals, and after RNA extraction and complementary DNA (cDNA) synthesis, gene expression of Arg1 was measured by real-time PCR. Results: The qPCR results showed that the expression of Arg1 was significantly increased in COVID-19 patients compared to healthy individuals (p < 0.01). The relative expression analysis demonstrated there were approximately 2.3 times increased Arg1 expression in the whole blood of COVID-19 patients. Furthermore, the receiver operating characteristic (ROC) analysis showed a considerable diagnostic value for Arg1 expression in COVID-19 (p = 0.0002 and AUC = 0.8401). Conclusion: Arg1 might be a promising marker in the pathogenesis of the disease, and it could be a valuable diagnostic tool.

Background Tumor immunology research has led to the identification of a number of tumor-associated self antigens, suggesting that most tumors trigger an immunogenic response, as is the case in osteosarcoma, where the detection of natural serum IgM antibodies might achieve the diagnosis of osteosarcoma. Natural IgM antibodies to tumor-associated proteins may expand the number of available tumor biomarkers for osteosarcoma and may be used together in a serum profile to enhance test sensitivity and specificity. Natural IgM antibodies can be consistently detected in the peripheral blood sera months to years before the tumor is diagnosed clinically. The study of the level of a potential biomarker many months (or years) prior to diagnosis is fundamentally important. Integrated circulating and imaging markers in clinical practice treating osteosarcoma have potential applications for controlling tumor angiogenesis. Objectives To study the expression of natural IgM antibodies to the tumor antigens of angiogenesis in the peripheral blood sera of osteosarcoma patients and healthy individuals, and to develop serum-based predictive biomarkers. Methods Peripheral venous blood samples were collected from 117 osteosarcoma patients and 117 patients with other tumors. All diagnosis was histologically confirmed. Staging of patients was performed according to the Enneking Surgical Staging System. The control group consisted of 117 age- and sex- matched healthy individuals. In this study, novel immunoconjugates were designed, synthesized and then used to develop a rapid, specific and sensitive enzyme-linked immunosorbent assay (ELISA) method to detect angiogenin (ANG)–IgM directly in the peripheral blood sera of humans. Results Serum ANG–IgM levels are significantly higher in osteosarcoma patients than in healthy individuals ( P < 0.005). Serum ANG–IgM levels varied widely, but were highly dependent on the concentration of IgM (r = 0.85; P < 0.0005). We found ANG–IgM in the sera of 85% of newly diagnosed osteosarcoma patients and ANG–IgM levels were significantly higher in osteosarcoma patients compared to any other tumors ( P < 0.001). Conclusions These results demonstrated that the combined biomarker ANG–IgM has greater sensitivity and specificity in early diagnosis of osteosarcoma patients than the traditional biomarkers (ANG and vascular endothelial growth factor). Circulating ANG–IgM immune complexes can potentially serve as a biomarker for increased risk of osteosarcoma, because relatively high serum levels were also detected in otherwise healthy individuals with a first degree family history of osteosarcoma and in patients with a diagnosis of benign conditions. Immunological aspects of angiogenesis for managing osteosarcoma will have a practical value in early diagnosis, prognosis and monitoring response to antiangiogenic therapy.

Abstract Background Currently, the role of serum-based biomarkers such as microRNAs in cancer diagnosis has been extensively established. This study aimed to determine expression levels of bioinformatically selected miRNAs and whether they can be used as biomarkers or a new therapeutic target in patients with Acute Lymphoblastic Leukemia (ALL). Materials and Methods The expression levels of serum miR-22, miR-122, miR-217, and miR-367 in 21 ALL patients and 21 healthy controls were measured using quantitative real-time PCR. The receiver operating characteristic (ROC) curve and the associated area under the curve (AUC) was used to assess candidate miRNAs' diagnostic value as a biomarker. Results The results showed that miR-217 was markedly decreased in patients with ALL compared to controls. Moreover, miR-22, miR-122, and miR-367 were found to be upregulated. Furthermore, ROC analysis showed that serum miR-217 and miR-367 could differentiate ALL patients from the healthy individuals, while miR-22 has approximate discriminatory power that requires further investigation. Conclusion Collectively, the results suggested that miR-217 may play a tumor suppressor role in ALL, whereas miR-22, miR-122, and miR-367 could function as an oncogene. Overall, miR-22, miR-217, and miR-367 could be considered possible biomarkers for the early diagnosis of ALL.

Abstract Objective This study aimed to establish a predictive model based on the clinical manifestations and laboratory findings in pleural fluid of patients with pleural effusion for the differential diagnosis of malignant pleural effusion (MPE) and tuberculous pleural effusion (TPE). Methods Clinical data and laboratory indices of pleural fluid were collected from patients with malignant pleural effusion and tuberculous pleural effusion in Zigong First People's Hospital between January 2019 and June 2020,and were compared between the two groups. Independent risk factors or Independent protective factors for malignant pleural effusion were investigated using multivariable logistic regression analysis. Receiver operating characteristic curve (ROC) analysis was performed to assess the diagnostic performance of factors with independent effects, and combined diagnostic models were established based on two or more factors with independence effect. ROC curve was used to evaluate the diagnostic ability of each model, and the fit of the eath model was measured using Hosmer-Lemeshow goodness-of-fit test. Results Patients with MPE were older than those with TPE, the rate of fever of patients with MPE was lower than that of patients with TPE, and these differences were statistically significant (p < 0.05). Carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), cytokeratin-19 fragment antigen (CYFRA21-1), cancer antigen 125 (CA125), and glucose (GLU) levels in the pleural fluid were higher, but total protein (TP), albumin (ALB) and Adenosine deaminase (ADA) levels in the pleural fluid were lower in MPE patients than in TPE patients, and the differences were statistically significant (P<0.05). In multivariate logistic regression analysis, CEA and NSE levels in the pleural fluid were independent risk factors for MPE, whereas ADA levels in pleural fluid and fever were independent protective factors for MPE. The differential diagnostic value of pleural fluid CEA and pleural fluid ADA for MPE and TPE were higher than that of pleural fluid NSE(p<0.05) and the area under the ROC curve was 0.901, 0.892, and 0.601, respectively. Four different binary logistic diagnostic models were established based on pleural fluid CEA combined with pleural fluid NSE, pleural fluid ADA or ( and ) fever. Among them, the model established with the combination of pleural fluid CEA and pleural fluid ADA (logit (P) = 0.513 + 0.457*CEA-0.101*ADA) had the highest diagnostic value for malignant pleural effusion, and its predictive accuracy was high with an area under the ROC curve of 0.968 [95% confidence interval (0.947, 0.988)]. But the diagnostic efficacy of the diagnostic model could not be improved by adding pleural fluid NSE and fever. Conclusion The model established with the combination of CEA and ADA in the pleural fluid has a high differential diagnostic value for malignant pleural effusion and tuberculous pleural effusion, and NSE in the pleural fluid and fever cannot improve the diagnostic efficacy of the diagnostic model.
