[Q]: High mobility group box 1 (HMGB1) protein has been identified as a novel pro-inflammatory cytokine in coronary artery disease (CAD). We investigated the relationship between serum HMGB1 level and the severity of coronary artery stenosis.', 'Serum HMGB1 concentration in patients was measured by ELISA. All patients underwent coronary angiography and were assigned into groups according to the quartile of HMGB1 level.', 'HMGB1 level in USAP group was higher than that in control and SAP group. HMGB1 level in SAP group was higher than that in control group (p<0.05). Gensini scores in the highest quartile group (group IV), group III and group II were all significantly higher than that in the lowest quartile group (group I). There was significant correlation between angiographic Gensini score and serum level of HMGB1 (r=0.710, p<0.05). However, in subgroup analysis, we found that serum HMGB1 level was only correlated with angiographic Gensini score in SAP patients (r=0.786, p<0.05), but not USAP patients.
[A]: Is increased serum HMGB1 related to the severity of coronary artery stenosis?


[Q]: IQ-domain GTPase-activating protein 1 (IQGAP1) binds to Dishevelled (Dvl) and functions as a modulator of Dvl nuclear localization in Xenopus embryos. However, the relationship between IQGAP1 and Dvl in tumor tissues is unclear.', 'We used immunohistochemistry to assess the expressions of IQGAP1 and Dvl in a cohort of 111 non-small cell lung cancer (NSCLC) patients. Association of their localization expressions with clinicopathological factors was also analyzed.', 'The positive rate of IQGAP1 in primary tumors was 48.6% (54/111) for its cytoplamic expression, 9.0% (10/111) for nuclear expression and 31.5% (35/111) for membranous expression; the positive rate of Dvl was 65.8% (73/111) for cytoplamic expression, 9.9% (11/111) for nuclear expression and 10.8% (12/111) for membranous expression. Coexpression rate of IQGAP1 and Dvl was 77.8% (42/54) in the cytoplasm, 80.0% (8/10) in the nucleus and 8.6% (3/35) in the membrane. Coexpression of IQGAP1 and Dvl in the cytoplasm and nucleus were significantly correlated (P<0.05), but not in the membrane (P>0.05). The positive expression rates of cyclin D1 and c-myc were significantly higher in the group of IQGAP1 and Dvl coexpression in the nucleus than that in the cytoplasm. Coexpression rate of IQGAP1 and Dvl in the cytoplasm and nucleus was significantly higher in lymph nodal metastases (63.3%, 19/30) than in primary growths (38.3%, 31/81), correlating with poor prognosis. Five-year survival time after resection in the group with their coexpression in the cytoplasm and nucleus was significantly lower than that with no coexpression (44.705±3.355 vs 58.403±2.543 months, p<0.05).
[A]: Is coexpression of IQ-domain GTPase-activating protein 1 ( IQGAP1 ) and Dishevelled ( Dvl ) correlated with poor prognosis in non-small cell lung cancer?


[Q]: The objective of this study was to describe a pattern of recovery and histological nerve cell loss in Sprague-Dawley rats exposed to severe brain ischemia and to compare it to that of Wistar rats.', 'Ether- and ketamine-anesthetized Sprague-Dawley rats were exposed to 3, 5, 6 and 10 min of normothermic severe brain ischemia (4 groups) induced by hypotension and neck compression. In group No. 5, the brain temperature was rapidly lowered, after 10 min of ischemia, to 30 degrees C during 45-50 min of recirculation. Wistar rats (group No. 6) served as controls (10-min normothermic ischemia).', 'In Sprague-Dawley (S-D) rats, post-ischemic audiogenic seizures (PAS) increased with the duration of ischemia and reached 86% (6/7 rats), after 10 min of ischemia. Mortality rate was high (50% = 7/14 rats). No seizure activity was observed after 10 min of ischemia in 6 Wistar (W) rats, and all survived. In the S-D rats, 10 min of ischemia produced histopathological damage in all brain regions examined, except in the thalamus. Damage was less severe in the W rats. Post-ischemic hypothermia ameliorated hippocampal and cortical nerve cell damage, but had no effect on the incidence of PAS activity and mortality. In W rats, hippocampal nerve cell loss was much less severe than in the S-D rats and cortical damage was not observed.
[A]:
Does post-ischemic hypothermia ameliorate ischemic brain damage but not post-ischemic audiogenic seizures in rats?
