Objective To determine the serum levels of triggering receptor expressed on myeloid cells-1 (TREM-1), analyse its relationship with inflammatory factors, and explore its clinical values. Methods Serum concentrations of TREM-1, TNF-α, IL-8 and IL-1β in 19 patients with early acute pancreatitis (AP) were measured by enzyme-linked immunoadsorbent assay and the relationship among them was analyzed, and it was compared with those of 20 normal controls. Results In patients with early AP, serum levels of TNF-α, IL-8, IL-1β and TREM-1 were (52.26±12.98) pg/ml, (20.18±9.81) pg/ml, (35.57 ± 13.34) pg/ml and (83.09 ± 32.49) pg/ml;while they were (18.69 ± 6.42) pg/ml, (9.81 ± 4.80) pg/ml, (14.94 ± 5.16) pg/ml and (8.44±8.42) pg/ml in control group, and there was significant difference between the two groups (P < 0.01). TREM-1 was positively correlated with other inflammatory factors in patients with early AP, and it had a sensitivity of 77.8%, specificity of 70.0% for prognosis prediction, which was better than TNF-α, IL-8, IL-1β. Conclusions TREM-1 may influence the leveLs of inflammatory factors and to some extent predict the early prognosis of AP.

Objective To study the relationship between fragile histidine traid (FHIT), pituitary tumor transforming gene-1 (PTTG-1) in thyroid tumor tissue. Methods The expression of FHIT and PTTG-1 were detected by immunohistocbemistry in 96 eases (56 carcinoma,40 adenoma). Results Compared with thyroid adenoma, the expression of FHIT decreased (P <0.01) ,PTTG-1 increased in thyroid carcinoma(P <0.01). The expression of FHIT is different in thyroid carcinoma in eancerometastasis to non-cancerometastasis (P < 0. 01), prognosis index (≥65) and prognosis index(< 65) (P < 0.01 and P < 0.05) ; There also was statistically significant differences between the expression of PTTG in thyroid carcinoma (P <0.05 and P <0.01). Conclusion FHIT and FTTG-1 may be an important reference significance in the differentiation of benign and malignant thyroid tumor tissue, and may serve as useful prognostic markers.
