METHODS: Eighty patients with SAP were randomized and received 100 mL/d of 20% AGD intravenously for 10 d starting either on the day of (early treatment group) or 5 d after (late treatment group) admission. Groups had similar demographics, underlying diseases, Ranson score, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, and Balthazar’s computed tomography (CT) score at the beginning of the study and underwent similar other medical and nutritional management. RESULTS: The duration of acute respiratory distress syndrome (2.7 ± 3.3 d vs 12.7 ± 21.0 d, P < 0.01), renal failure (1.3 ± 0.5 d vs 5.3 ± 7.3 d, P < 0.01), acute hepatitis (3.2 ± 2.3 d vs 7.0 ± 7.1 d, P < 0.01), shock (1.7 ± 0.4 d vs 4.8 ± 3.1 d, P < 0.05), encephalopathy (2.3 ± 1.9 d vs 9.5 ± 11.0 d, P < 0.01) and enteroparalysis (2.2 ± 1.4 d vs 3.5 ± 2.2 d, P < 0.01) and hospital stay (28.8 ± 9.4 d vs 45.2 ± 27.1 d, P < 0.01) were shorter in the early treatment group than in the late treatment group. The 15-d APACHE Ⅱ score was lower in the early treatment group than in the late treatment group (5.0 ± 2.4 vs 8.6 ± 3.6, P < 0.01). The infection rate (7.9% vs 26.3%, P < 0.05), operation rate (13.2% vs 34.2%, P < 0.05) and mortality (5.3% vs 21.1%, P < 0.05) in the early treatment group were lower than in the late treatment group.CONCLUSION: Early treatment with AGD achieved a better clinical outcome in SAP patients.展开更多

METHODS: The cervical spondylosis model in rats was established by destroying the stability of cervical posterior column. The cord segments C4-6 and gastric antrum were collected 3 mo and 5 mo after the operation. Rats with the sham operation were used as controls. The expressions of c-Fos, caspase-3 and IL-1β in the cervical cord and gastric antrum were determined by immunohistochemistry and/or Western blot. RESULTS: Immunohistochemical staining showed a few c-Fos, caspase-3 and IL-1β-positive cells in the cervical cord and antrum in the control. There was a significant increase in c-Fos, caspase-3 and IL-1β expression in model groups compared to the control groups at 3 mo and 5 mo after operation. More importantly, there was a significant (P < 0.05) increase in c-Fos, caspase-3 and IL-1β expression in the model group rats at 3 mo compared to those at 5 mo after the operation (c-Fos: 11.20 ± 2.26 vs 27.68 ± 4.36 in the cervical cord, 11.3 ± 2.3 vs 29.3 ± 4.6 in the gastric antrum; caspase-3: 33.83 ± 3.71 vs 36.32 ± 4.01 in the cervical cord, 13.23 ± 3.21 vs 26.32 ± 4.01 in the gastric antrum; IL-1β: 42.06 ± 2.95 vs 45.91 ± 3.98 in the cervical cord, 26.56 ± 2.65 vs 32.01 ± 2.98 in the gastric antrum). Western blotanalysis showed time-dependent changes of caspase-3 and IL-1β protein in the cervical cord and gastric antrum of rats with cervical spondylosis; there was no significant expression of caspase-3 and IL-1β protein in the control group at 3 mo and 5 mo after the sham operation, whereas there was a significant difference in caspase-3 and IL-1β protein levels between the model group rats followed up for 3 mo and those for 5 mo (P < 0.05). CONCLUSION: There is a significant association of c-Fos, caspase-3 and IL-1β expressions in the gastric antrum with that in the spinal cord in rats with cervical spondylosis, suggesting that the gastrointestinal function may be affected by cervical spondylosis.展开更多
