ABSTRACT
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.
ABSTRACT
@#Objective To summarize the results of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) IgG antibody, total antibody and cellular immune function of COVID-19 convalescent patients one year after discharge, and to analyze the correlation between the SARS-CoV-2 antibody and the indexes of immune function. Methods A total of 41 confirmed COVID-19 patients discharged from Chengdu Public Health Clinical Medical Center from January to April 2020 and followed up one year after discharge were included in the study as the research group, including 18 males and 23 females with an average age of 47.83±12.95 years. The results of SARS-CoV-2 IgG, total antibody and immune function indexes one year after discharge were collected in order to discuss the correlation of SARS-CoV-2 and cellular immune function. A total of 40 healthy employees of the hospital vaccinated against COVID-19 were randomly selected as the vaccine group, including 10 males and 30 females with an average age of 43.90±6.86 years. The SARS-CoV-2 antibodies between the two groups were compared. Results CD8+T cell count was higher and CD4+T/CD8+T was lower in male patients than those in female patients (all P<0.05). The IgG and total antibodies in patients with re-detectable positive RNA test were both higher than those in patients without re-detectable positive RNA test, but the differences were not statistically significant (P=0.158, 0.060). The positive rate of SARS-CoV-2 IgG in the research group was 80.5% (33/41). SARS-CoV-2 IgG was positively correlated with total antibody (P<0.001). There was a positive correlation between CD4+T cell count and SARS-CoV-2 IgG (r=0.455, P=0.003). The positive rate of SARS-CoV-2 IgG, SARS-CoV-2 IgG amount and total antibody amount in the research group were significantly higher than those in the vaccine group (all P<0.001). Conclusion SARS-CoV-2 IgG of most COVID-19 patients one year after discharge is positive, and their SARS-CoV-2 total antibody is significantly higher than people vaccinated against COVID-19, which suggests that patients infected with SARS-CoV-2 can obtain lasting protection, but the protection may be gradually weaken over time. The degree of antibody attenuation in patients with re-detectable positive RNA test may be weaker. In the convalescence stage, the dynamics of SARS-CoV-2 IgG may be closely related to cellular immune function.

ABSTRACT
Objective To analyze the characteristics of cellular immune function and its prognostic risk factors in patients with community-acquired pneumonia (CAP). Methods The clinical data of patients diagnosed as CAP admitted to department of respiratory and critical care medicine of the Second Affiliated Hospital of Anhui Medical University from June 2018 to February 2019 were retrospectively analyzed. The patients were divided into survival group and death group according to the mortality at discharge and 28-day survival after hospital discharge; in addition, they were divided into bacterial group, fungi group and mixed infection group according to pathogen results at discharge. The differences of general clinical characteristics, arterial blood gas analysis indexes, plasma albumin, cellular immune function, inflammatory cytokines, the length of hospital stay among groups were analyzed. The correlation between the prognosis-related indicators in patients were analyzed by Pearson test or Spearman test, and Logistic regression model was used to analyze the risk factors of patients in non-survival group. Results 106 patients were finally enrolled, 69 of whom were survived, and 37 dead. Among 56 patients with pathogen results, 27 were diagnosed as bacterial infection, 11 as fungal infection, and 18 with mixed infection. Compared with the survival group, plasma albumin level, total T cell count, CD4+ T cell count, CD8+ T cell count were decreased in the death group, temperature, pH, acute physiology and chronic health evaluationⅡ(APACHEⅡ), procalcitonin (PCT), interleukin-6 (IL-6), C-reactive protein (CRP) were increased, and the length of hospital stay was significantly shortened. While there was no significant difference in gender, age, mean arterial pressure, arterial oxygen pressure, CD4+/CD8+, regulation T cell/effect T cell (TREG/TEF) between the two groups. Correlation analysis showed that plasma albumin, the length of hospital stay, APACHEⅡ score, CD4+ T cell count, CD8+ T cell count, CD4+/CD8+, PCT, IL-6, CRP were correlated with death (r value was -0.480, -0.209, 0.203, -0.279, -0.270, 0.271, 0.247, 0.410, 0.329, all P <0.05). Logistic regression analysis showed that plasma albumin, CD4+ T cell count, CD8+ T cell count, CD4+/CD8+decreased; APACHEⅡ score, PCT, IL-6, and CRP increased; the length of hospital stay were correlated with death, and all were independent risk factors for death in CAP patients (all P < 0.05). Correlation analysis showed that the APACHEⅡ score was negatively related to plasma albumin (r = -0.375, P < 0.05), positively related to CRP and IL-6 (r value was 0.363 and 0.333 respectively, both P < 0.05); negative correlation between plasma albumin and IL-6 (r = -0.372, P < 0.05), PCT and CD4+ T cell count (r = -0.354, P < 0.05), CRP and the length of hospital stay (r = -0.356, P < 0.05). There were no significant correlations between the others. There was no significant difference in cellular immune function or inflammatory factor expression between different pathogenic infections. Conclusions Cellular immune dysfunction, hypoproteinemia, APACHEⅡ score and elevated inflammatory index are all influential factors for the death of CAP patients. Apart from conventional anti-infective treatment, the symptoms of hypoproteinemia and cellular immune function can predict the severity and prognosis of CAP patients.
