Objective:To analyze the results of lymphocyte subsets and 12 plasma cytokines in patients with tuberculosis by flow cytometry and to evaluate their diagnostic efficacy in these patients.Methods:This is a retrospective case-control study. A total of 128 patients with evidence of tuberculosis disease or clinically confirmed tuberculosis who were admitted to the 8th Medical Center of PLA General Hospital from January 2022 to December 2023 were included. According to the location of mycobacterium tuberculosis infection, the patients were divided into the pulmonary tuberculosis group (83 cases) and the extrapulmonary tuberculosis group (45 cases), and 100 healthy age-and sex matched people who underwent health check up during the study period were selected as the control group. Flow cytometry was used to detect peripheral blood lymphocyte subsets and 12 plasma cytokines [including 10 pro-inflammatory factors: interleukin (IL)-5, interferon (IFN)-α, IL-2, IL-6, IL-1β, IFN-γ, IL-8, IL-17, IL-12P70, Tumor necrosis factor (TNF)-α, and two anti-inflammatory factors: IL-4, IL-10] in participants of all groups. Spearman correlation method was used to analyze the correlation between lymphocyte subsets and cytokines, binary Logistic regression was used to screen the TB related factors, and receiver operating curve (ROC) was used to evaluate the diagnostic efficacy of TB related factors.Results:Compared with the control group, the absolute number of CD3 +T lymphocytes, CD3 +CD8 +T lymphocytes, CD3 +CD4 +T lymphocytes, NK cells and B cells were lower in pulmonary tuberculosis group and extrapulmonary tuberculosis group (all P<0.05). Except for IL-1β, the levels of other 11 cytokines are all significantly higher in the pulmonary tuberculosis group (all P<0.01), and the levels of IL-6, IFN-γ, IL-17, TNF-α, IL-4 and IL-10 were significantly higher in extrapulmonary tuberculosis group (all P<0.05). Compared with extrapulmonary tuberculosis group, the level of IL-8 was higher in pulmonary tuberculosis group ( P=0.026). Spearman correlation analysis showed that IL-6, IFN-γ and IL-8 were negatively correlated with the absolute numbers of CD3 +T lymphocytes, CD3 +CD8 +T lymphocytes, CD3 +CD4 +T lymphocytes, NK cells and B cells (IL-6: R2=-0.30, -0.28, -0.32, -0.26, -0.28; IFN-γ: R2=-0.36, -0.31, -0.37, -0.25, -0.36; IL-8: R2=-0.14, -0.13, -0.16, -0.14, -0.22; all P<0.05), IL-10 was negatively correlated with the absolute number of CD3 +CD4 +T lymphocytes, NK cells and B cells ( R 2=-0.14, -0.19, -0.21, all P<0.05); Binary Logistic regression analysis showed that IL-6, IFN-γ, IL-8 and IL-10 were the related factors of tuberculosis ( OR=1.809, 1.136, 0.910, 2.218, all P<0.05), ROC curve analysis showed that the AUC of IL-6, IFN-γ, IL-8 and IL-10 in the joint diagnosis of tuberculosis was 0.845, the sensitivity was 0.766, and the specificity was 0.820. Conclusion:The lower absolute number of lymphocyte subsets and cytokine levels in patients with pulmonary tuberculosis and extrapulmonary tuberculosis indicate that their immune function is in a low state, and the higher levels of pro-inflammatory factors (IL-6, IFN-γ, IL-8) and anti-inflammatory factor (IL-10) indicates the higher inflammatory status, and evaluation of these 4 cytokines has satisfactory diagnostic efficacy for tuberculosis.

Objective:This study aims to establish an early warning diagnosis model for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and to provide a simple, rapid, and accurate auxiliary diagnosis basis for clinical practice.Methods:The sample bank of subjects (patients admitted to the Eighth Medical Center of the PLA General Hospital from September 10, 2021, to July 25, 2023) was constructed, including the model establishment cohort [SCOPD group 49, 42 males and 7 females, (69.71±11.16) years old; AECOPD group 53, 49 males and 4 females, (72.60±10.19) years old] and the model validation cohort [SCOPD group 35, 28 males and 7 females, (69.97±10.40) years old; AECOPD group 35, 33 males and 2 females, (71.43±9.67) years old]. Fasting peripheral blood samples were collected, and the expression levels of IL-5, IL-17A, and IFN-α were detected by flow cytometry. Different expression levels were analyzed by Mann-Whitney U test. Binary logistic regression analysis was used to screen the related risk factors of COPD patients in acute exacerbation. The diagnostic efficacy of the model was evaluated by the receiver operating characteristic (ROC) curve.Results:The levels of IL-5 [1.64 (0.60, 2.86) pg/ml], IL-17A [1.42 (0.88, 2.29) pg/ml], and IFN-α [0.91 (0.59, 1.81) pg/ml] in the SCOPD group were significantly decreased compared with the AECOPD group IL-5 [4.68 (2.34, 9.40) pg/ml, Z=-5.033, P<0.001], IL-17A [2.33 (1.59, 4.62) pg/ml, Z=-3.919, P<0.001], IFN-α [2.83 (0.91, 3.75) pg/ml, Z=-4.127, P<0.01] in the cohort of model establishment. The results of binary logistic regression analysis between SCOPD and AECOPD groups showed that IL-5, IL-17A, and IFN-α were independent risk factors for acute exacerbation of patients with COPD ( P<0.05). And the regression equation is Y=-2.861+0.364×IL-5+0.385×IL-17A+0.445×IFN-α. The AUC value of IL-5, IL-17A, IFN-α and combined detection was 0.866 ( P<0.001). Compared to the SCOPD group and the AECOPD group in the cohort of model validation, the receiver operating characteristic (ROC) curve showed that the combined model of three (AUC=0.858, P<0.001) could be used to diagnose the AECOPD. And the Kappa value was 0.773( P<0.05). Conclusion:The combined detection of IL-5, IL-17A, and IFN-α has high diagnostic efficacy for patients with acute exacerbation of COPD. This method provides a new potential tool for the clinical diagnosis of AECOPD and has the value of further exploration and optimization, promotion, and application.

Objective:To study the relationship between white matter injury (WMI) and brain maturity in preterm infants at full-term corrected gestational age (cGA).Methods:A retrospective study was performed in preterm infants [GA≤32 weeks or birth weight (BW) ≤1 500 g] admitted to the neonatal intensive care unit of the First Affiliated Hospital of Xi'an Jiaotong University from January 2017 to August 2018 and the Northwest Women and Children's Hospital from January 2017 to June 2017. The infants received conventional magnetic resonance imaging (MRI) at cGA 37~42 weeks. The infants were assigned into the WMI group and the control group according to the WMI scoring system, including the total maturation scores (TMS) and four sub-item scores.Results:A total of 118 premature infants were enrolled in this study (17 cases in the WMI group and 101 cases in the control group). The GA was (30.3±1.7) weeks, and BW was (1 356±268) g. The proportion of delayed TMS in the WMI group was significantly higher than the control group [58.8%(10/17) vs. 31.7%(32/101), P<0.05]. The TMS of the WMI group were significantly lower than the control group [(10.7±1.8) vs. (11.8±1.5), P<0.05]. The sub-item scores of TMS showed that the myelination [(2.8±0.6) vs. (3.1±0.4), P<0.05] and glial cell migration bands of the WMI group [(1.6±0.4) vs. (2.1±0.6), P=0.004] were significantly lower than the control group and no significant differences existed in cortical folding and involution of germinal matrix tissue scores between the two groups. Conclusions:The brain maturity of preterm infants with WMI is substantially delayed than those without WMI, including delayed myelination and delayed disappearance of glial cell migration bands.
