[Abstract]:[Objective] 1. To detect the expression of microRNA-9, microRNA-21 and microRNA-501 in serum and plasma of patients with non-small cell lung cancer (NSCLC), and to explore the possibility of microRNA-9, microRNA-21 and microRNA-501 as biomarkers in peripheral blood of NSCLC patients with high sensitivity and specificity. To explore the expression of microRNAs in serum and plasma. 3. To analyze the relationship between the expression of microRNAs in serum and plasma and clinicopathological parameters in patients with non-small cell lung cancer, and to compare the expression of microRNAs with serum tumor markers currently used in clinic, to explore whether the microRNAs can be used to monitor the recurrence of non-small cell lung cancer. [Methods] 1. To collect the case data of patients who met the admission criteria and collect the fasting blood (anticoagulant 10ml, non-anticoagulant 10ml) in the morning after admission. Serum and plasma were separated and stored in Jie. MicroRNAs were extracted from serum and plasma of healthy people, non-small cell lung cancer patients, and amplified by qRT-PCR to detect the expression of microRNAs. The expression levels of microRNAs were compared among the three groups. The relative expression of microRNAs-21 and microRNAs-501 was formulated as follows: 2-delta CT.3. The expression levels of microRNAs-9, microRNAs-21 and microRNAs-501 in serum, plasma and clinical pathological parameters of lung cancer and serum tumor markers were analyzed. The sensitivity and specificity of serum tumor markers CEA, CA125, CA153, CA199, CA242, CA724, FER, CYFRA21-1, NSE and SCC were calculated respectively, and the area under ROC curve was calculated. [Results] 1. The expression levels of serum and plasma microRNAs-9, microRNA21 in healthy people and patients with non-small cell lung cancer were high, and the difference was statistically significant (P 0.05). There was no significant difference in the expression of - 501 between healthy and non-small cell lung cancer patients (P 0.05). 2. The expression level of serum microRNA-9 in healthy group was 1.15 [0.76] and non-small cell lung cancer group was 3.39 [3.75]. Compared with healthy group, the expression level of non-small cell lung cancer group was higher than that in healthy group, the difference was statistically significant (P 0.05). The expression level of serum microRNAs-501 in healthy group was 1.84 [2.04] and that in non-small cell lung cancer group was 2.30 [3.02] and that in healthy group was higher than that in healthy group (P 0.05). The expression level of serum microRNAs-501 in healthy group was 1.84 [2.04] and that in non-small cell lung cancer group was 2.30 [3.02] respectively. There was no significant difference between the two groups (P 0.05). The expression level of plasma microRNAs-9 in healthy group was 1.12 [0.70] and that in non-small cell lung cancer group was 3.41 [3.73]. Compared with healthy group, the expression level of plasma microRNAs-21 in non-small cell lung cancer group was higher than that in healthy group, the difference was statistically significant (P 0.05). The expression level of plasma microarray-501 in healthy group was 1.84 [2.06] and that in lung cancer group was 3.27 [3.60] and that in non-small cell lung cancer group was higher than that in healthy group (P 0.05). There was no significant difference between the two groups (P The expression of microRNA-9 and microRNA-21 was not correlated with sex, age, TNM stage and metastasis (P 0.05). MicroRNA-21 was not correlated with pathological type (P 0.05). MicroRNA-9 was correlated with pathological type (P 0.05). The level of microRNA-9 in peripheral blood circulation increased (P 0.05). The increased levels of microRNAs in peripheral blood circulation were associated with the increased levels of FER, Cyfra21-1, NSE and CA153, (P 0.05). 6. The specificity and sensitivity of detecting microRNAs-9 and microRNAs-21 in peripheral blood circulation of patients with non-small cell lung cancer were not completely superior to those of tumor markers CEA, CA125, CA153, CA199, CA242, CA724, FER, CYFRA-12, NSE, SC, CA242, CA724, FER, CYFRA-12, NSE, and SCE. Among them, the area under the ROC curve of microRNAs-9 was 0.75, and the diagnostic accuracy was moderate. 7. The specificity, sensitivity and area under the ROC curve of the four combined tumor markers (microRNAs-9, CEA, CA724, CYFRA21-1) were 95.0%, 82.0% and 0.950 respectively. The diagnostic accuracy of microRNAs-9 and microRNAs-21 was high in peripheral blood circulation of non-small cell lung cancer patients. Detecting the expression of microRNA-9 and microRNA-21 in peripheral blood circulation can be used for the diagnosis of non-small cell lung cancer. MicroRNA-9 and microRNA-21 in peripheral blood circulation have the potential to become biomarkers of non-small cell lung cancer. The expression level can improve the diagnostic accuracy of non-small cell lung cancer, reduce the false positive rate, and is more specific and sensitive.
