AIM: To investigate the effect of single immunoglobin IL-1 receptor related protein (SIGIRR) on damage of alveolar epithelial cells in acute lung injury induced by lipopolysaccharide. METHODS: The acute alveolar epithelial cell injury model was constructed by stimulation of A549 cells with LPS. In order to over-express SIGIRR, the A549 cells were transferred with eukaryotic expression vector containing full length SIGIRR cDNA. The transcriptional activity of NF-κB was measured by dual-luciferase reporter assay system. The concentrations of IL-1β, TNF- α and IL-6 were detected by ELISA. The levels of these inflammatory factors between the transfected cells and untransfected cells were compared. RESULTS: The over-expression of SIGIRR inhibited the transcriptional activity of NF-κB. The increases in IL-1β, TNF-α and IL-6 concentrations in alveolar epithelial cells induced by LPS were observed. CONCLUSION: SIGIRR in alveolar epithelial cells inhibits TLR4 signals triggered by LPS and attenuates the inflammatory reactions in alveolar epithelial cells, which plays a protective role against the acute damage of the alveolar epithelial cells.

Objective To investigate the relationship between acute biliary pancreatitis (ABP) and anomalous pancreaticobiliary duetal union (APBDU). Methods 131 patients with ABP were enrolled to test the serum total bilirubin (TB), alanine amintransferase (ALT), aspartate amintransferase (AST), alkaline phosphates (ALP), γ-glutamyl transferase (γ-GT). All the patients received medical treatment, and then these tests were performed again. Thereafter, all the patients underwent selective surgery and intra-operative cholangiography was performed to observe the pancreaticobiliary duetal union. Results 27 patients (20.6%) with APBDU were found in 131 patients. Among them, 8 cases (29.6%) was B-P subtype (TypeⅠ), 16 cases (59.3%) was P-B subtype (TypeⅡ) , and the remaining 3 cases was mixed subtype (TypeⅢ). A significant decrease of ALT, AST, ALP, γ-GT after non-surgical treatment in both group of APBDU and NAPBDU was noted (P<0.05). The serum levels of ALT, AST,γ-GT in APBDU patients were (71.81± 23.19) U/L, (47.85±27.87) U/L, (52.86±31.49) U/L, respectively; and in NAPBDU patients were (51.96±15.40) U/L, (40.77±16.58) U/L, (34.86±26.47) U/L. The difference was statistically significant (P<0.05). Condusions APBDU is an important etiology of ABP.

Objective To investigate the clinical value of the test injection at popliteal arteries on 64-slice CTA in lower extremity peripheral arterial occlusive disease (PAOD). Methods Twenty-eight patients with PAOD referred for 64-slice CTA were enrolled consecutively in the study. Test injection was performed at bilateral popliteal arteries (the level of knee joints) and the clinic value of the peak value and the time to peak was analyzed. The relationship between the time to peak and the peak value was evaluated with Pearson test. The time to peak was used for programming of the CT angiographic acquisitions with fast scanning mode. The quality of visualization of each arterial segment was determined independently by two radiologists. Results Fifty-four (96%, 54/56) time-attenuation curves were obtained in 28 patients. The wide interindividual variation in the peak value and the time to peak was observed in 52 curves of 26 patients with range of 60-178 HU,21-46 s and an average of (135±28) HU,(31±6) s, respectively. The difference in the peak value and the time to peak between bilateral popliteal arteries was also observed with range of 10-80 HU and an average of (32±18) HU in 19 patients,with range of 1-12 s and an average of (5±3) s in 21 patients. There was negative relationship between the peak value and the time to peak (r=-0.526, P<0.01). The CTA images were of good (598 segments) or medium quality (12 segments) in 99% segments (610/616). Conclusions The test injection at popliteal arteries was useful for 64-slice CTA in the patients with PAOD, as it could accurately specify the delay time of CT angiographic acquisitions.
