Receiver operating characteristic (ROC) analysis showed that serum GPI could screen KOA patients from controls.

Collectively, elevated serum GPI concentration contributed to the progression of KOA, and targeting GPI may be useful for the therapy of KOA.

South Korea is the only Organisation for Economic Co-operation and Development (OECD) country with a high incidence of tuberculosis (TB). Healthcare workers (HCWs) have an increased risk of TB infection. QuantiFERON-TB Gold In-Tube (QFT-GIT) testing is performed for occupational health screening to detect latent TB infection (LTBI).

We evaluated the introduction of new criteria for borderline ranges for interferon-gamma release assay (IGRA) results in HCWs. The results of QFT-GIT tests in HCWs in 2017 and 2018 were collected, with high-risk HCWs having two serial test results. Existing dichotomous criteria and new criteria with borderline ranges (bor-derline negative [BN], 0.20 - 0.34 IU/mL; borderline positive [BP], 0.35 - 0.99 IU/mL) were applied to each test re-sult.

After applying the borderline range, 26.4% of the positive results were classified as BP (4% of total results), while 4.2% of the negative results were classified as BN (3.6% of total results). Among seven HCWs with initial results in the borderline range, two had repeated borderline results while 71.4% had low negative results.

We recommend the introduction of borderline ranges in the interpretation of QFT-GIT results to reduce unnecessary TB therapy in HCWs.

To explore the expression of serum TLR4 and NF-κB levels in neonatal jaundice.

A total of 63 jaundice infants admitted to our hospital from January 2017 to January 2018 were enrolled into the experimental group (34 pathological jaundice infants and 29 physiological jaundice infants). The serum TLR4 level (0.5 ng/mL as positive expression) was determined by immunohistochemical staining, and the serum NF-κB level in peripheral blood was determined by ELISA. A total of 40 healthy infants with simultaneous blood sampling and physical examination were enrolled into the control group to measure the levels of TLR4 and NF-κB which were compared between the two groups.

The levels of serum TLR4 and NF-κB in the infants in the experimental group were higher than those in normal newborns in the same period, the difference between the two groups was statistically significant (p < 0.05), and the levels of TLR4 and NF-κB showed a gradual downtrend after treatment. TLR4 expressions were positive in pathologic and physiologic jaundice infants of the experimental group, and negative in the control group. The correlation analysis showed that the elevated levels of TLR4, NF- kb, IL-Iβ, and TNF-α were risk factors for jaundice.

The elevated levels of TLR4 and NF-κB are the main factors of neonatal jaundice. TLR4, NF- kb, IL-Iβ, and TNF-α are closely related to the onset of jaundice, which can be used as an important marker in clinical diagnosis of neonatal jaundice.

CC chemokine ligand-18 (CCL-18) and CX3 chemokine ligand 1 (CX3CL1) are key factors of vascular and tissue injury in chronic respiratory diseases. Here, we investigated the value of CCL-18 and CX3CL1 in diagnosis and prognosis of patients with chronic obstructive pulmonary disease and chronic cor pulmonale (COPD&CCP).

First, we investigated the expression profile of CCL-18 and CX3CL1 in serum of COPD&CCP patients. Then the relationship of the level of CCL-18 and CX3CL1 with clinicopathological characteristics was analyzed. Subsequently, we evaluated the diagnostic accuracy of CCL-18 and CX3CL1 to discriminate COPD&CCP. The prognostic value and therapy outcome were also evaluated.

Compared to healthy subjects, the level of CCL-18 (8.01 ± 2.01 ng/mL) and CX3CL1 (2,096.11 ± 306.09 ng/mL) was significantly increased in COPD&CCP patients (p < 0.05). The upregulation of CCL-18 and CX3CL1 was significantly correlated with clinicopathological characteristics including CRP, IL-6, FIB, NT-proBNP, FEV1, FEV1/FVC, PASP, LVEF, and T wave anomaly. Fasudil ROCK inhibitor The combination of CCL-18 and CX3CL1 showed high precision for discriminating COPD&CCP with high AUC values (0.828), sensitivity (66.1%), and specificity (92.5%). Furthermore, CCL-18 and CX3CL1 acted as independent factors which lead to poor clinical benefits and indicated poor prognosis of COPD&CCP patients.

Taken together, our results indicated that CCL-18 and CX3CL1 could act as suitable biomarkers in prognosis and prognostic evaluation of COPD&CCP.

The current study aims to investigate the diagnostic value of serum proinflammatory factors, including IL-6, TNF-α, and leptin, in patients with post-traumatic osteoarthritis (PTOA).

The serum levels of IL-6, TNF-α, and leptin were detected by enzyme linked immunosorbent assay (ELISA). Pearson's correlation assay was performed to evaluate the correlation between serum levels of IL-6, TNF-α, and leptin. ROC analysis was carried out to explore the diagnostic value of IL-6, TNF-α, and leptin for PTOA patients.

Compared with the control group, the levels of IL-6, TNF-α, and leptin in the serum of patients with PTOA were significantly higher. Moreover, the levels of IL-6, TNF-α, and leptin increased along with Kellgren Lawrence (K-L) grading in patients with PTOA. Pearson's correlation analysis showed that serum IL-6 was positively correlated with TNF-α and leptin, and TNF-α was positively correlated with leptin. More importantly, the AUC of combined serum IL-6, TNF-α, and leptin levels in PTOA patients was 0.
