OBJECTIVE@#To analyze the correlation between the mRNA levels of breast cancer resistance protein (BCRP) and lung-specific X protein (LUNX) genes with pathological types and stages of patients with non-small cell lung cancer (NSCLC) and their significance for prognosis.@*METHODS@#Eighty nine patients with NSCLC admitted to Huaihe Hospital of Henan University between June 2015 and June 2018 were recruited, with 55 patients with benign lung lesions admitted during the same period of time selected as the control group. The mRNA levels of BCRP and LUNX genes were detected in the peripheral blood samples from the two groups, and their correlation with the clinicopathological characteristics and prognosis of the patients was analyzed.@*RESULTS@#The expression rates of BCRP and LUNX mRNA in the NSCLC group were significantly higher compared with the control group (P < 0.05). The level of BCRP mRNA of the NSCLC patients has correlated with the degree of differentiation and TNM staging (P < 0.05), but not with gender, age, smoking, pathological types and lymph node metastasis (P > 0.05). The level of LUNX mRNA of them has correlated with the degree of differentiation, TNM staging and lymph node metastasis (P < 0.05), but not with gender, age, smoking, and pathological types (P > 0.05). Compared with those with no expression, the overall survival rate of patients with BCRP and LUNX expression was significantly lower (P < 0.05). The degree of differentiation, TNM staging, lymph node metastasis, and expression of the BCRP and LUNX mRNA may all affect the prognosis of the patients.@*CONCLUSION@#The levels of BCRP and LUNX mRNA in the peripheral blood of patients with NSCLC are significantly increased. The expression of BCRP mRNA is correlated with the degree of differentiation and TNM staging, whilst the expression of LUNX mRNA is correlated with the differentiation degree, TNM staging and lymph node metastasis. Both may be used as independent predictors for the prognosis of patients with NSCLC.

Objective:To investigate the relationship between serum leukocyte-associated immunoglobulin-like receptor 2 (LAIR2) expression and cellular immune function, prognosis in patients with non-small cell lung cancer.Methods:From April 2016 to April 2017, 90 patients with non-small cell lung cancer who were treated in Shangqiu first people’s Hospital were taken as the lung cancer group, and they were grouped into the survival group and the death group according to whether the patients died within 5 years. Another 84 patients with benign pulmonary mass were selected as the control group. The levels of CD4+[ (28.26±5.14) % vs (47.02±6.73) %], CD8+ [ (23.76±5.84) % vs (30.12±6.03) %] and CD4+/CD8+ [ (1.17±0.30) % vs (1.56±0.50) %] in peripheral blood immune cells were detected by flow cytometry; the serum LAIR2 level was detected by enzyme-linked immunosorbent assay (ELISA) , and the average serum LAIR2 level of patients with non-small cell lung cancer was applied as the boundary, and they were grouped into a low LAIR2 expression group and a LAIR2 high expression group; Pearson correlation was applied to analyze the correlation between serum LAIR2 level and immune cell level in patients with non-small cell lung cancer; Kaplan-Meier curve was applied to analyze the relationship between serum LAIR2 level and 5-year survival rate of patients with non-small cell lung cancer; and multivariate COX regression analysis was applied to analyze the factors affecting 5-year mortality in patients with non-small cell lung cancer.Results:The level of serum LAIR2 [ (69.55±13.12) ng/ml vs. (20.64±7.13) ng/ml] in the lung cancer group was significantly higher than that in the control group, and the levels of CD4 +, CD8 + and CD4+/CD8+ were significantly lower than those in the control group ( P<0.05) . The serum LAIR2 level in patients with TNM stage III+IV (77.32±13.09) ng/ml, poorly differentiated tissue (78.14±13.26) ng/ml, and lymph node metastasis (79.02±13.81) ng/ml was significantly higher than that in patients with TNM stage I+II (64.37±12.89) ng/ml, medium/well differentiated tissue (64.32±12.73) ng/ml, and no lymph node metastasis (62.92±12.85) ng/ml ( P<0.05) . The levels of CD4 +, CD8 + and CD4 +/CD8 + in the LAIR2 high expression group were significantly lower than those in the LAIR2 low expression group ( P<0.05) . Serum LAIR2 level in patients with non-small cell lung cancer was negatively correlated with CD4+, CD8+ and CD4+/CD8+ levels ( r=-0.510, -0.496, -0.494, P<0.05) . The 5-year survival rate of patients with high LAIR2 expression was lower than that of patients with low LAIR2 expression ( r=6.375, P<0.05) . LAIR2 was an independent risk factor for 5-year death in patients with non-small cell lung cancer ( P<0.05) . Conclusion:LAIR2 is highly expressed in serum of patients with non-small cell lung cancer, and its expression level is closely related to cellular immune function and prognosis.
