Objective To investigate the correlation between microembolic signal (MES) and immune inflammation in patients with acute ischemic stroke. Methods The consecutive patients with acute ischemic stroke were enroled. According to the results of MES, they were divided into either a positive group or a negative group. The Immune inflammatory indexes, demographics, and baseline clinical data in both groups were compared. Multivariate logistic regression analysis was used to analyze the independent influencing factors of MES in acute ischemic stroke. Results A total of 237 patients were enroled, including 52 in the MES positive group and 185 in the MES negative group. There were significant differences in the levels of triglyceride (2. 130 ± 0. 933 mmol/L vs. 1. 811 ± 0. 962 mmol/L; t = 2. 126, P = 0. 035), plasma fibrinogen (2. 946 ± 0. 255 g/L vs. 2. 833 ± 0. 322 g/L; t = 2. 332, P = 0. 021 ), Lp-PLA2 level ( 288. 265 ± 27. 855 μg/L vs. 261. 652 ± 29. 961 μg/L; t = 2. 897, P = 0. 004 ), as wel as the proportions of CD4 + CD25high Treg (8. 695% ± 1. 461% vs. 9. 445% ± 1. 397% ; t = 3. 386, P = 0. 001), artery stenosis ≥70% (21. 15% vs. 5. 41% ; χ2 = 10. 592, P = 0. 001 ) and smal arterial occlusive stroke (9. 62% vs. 23. 24% ; χ2 = 4.667, P = 0. 031) between the MES positive group and the MES negative group. Multivariate logistic regression analysis showed that the increased plasma fibrinogen level (odds ratio [OR] 3. 257, 95%confidence interval [CI] 1. 124 - 9. 438; P = 0. 030), artery stenosis ≥ 70% (OR 3. 585, 95% CI 1. 394 -9. 219; P = 0. 008), and the decreased ratio of Treg (OR 3. 801, 95% CI 1. 190 - 12. 148; P = 0. 024) were the independent risk factors for positive MES, and smal arterial occlusive stroke was its independent protective factor (OR 0. 244, 95% CI 0. 072 - 0. 829; P = 0. 024). Conclusions MES may be associated with immune inflammation. The relationship between stroke and immune inflammation should be taken seriously.

OBJECTIVETo study the impact of total flavones from Artemisia anomala (TFAS) on activation of macrophages, cell oxidative stress, auto-nitration of CuZn-SOD, platelet aggregation and isolated vascular tension.
METHODLPS and IFN-gamma induced activation of macrophages and oxidative stress in rats; H2O2 and nitrite induced auto-nitration of CuZn-SOD; ADP, AA and collagen induced platelet aggregation in vitro in mice; PE stimulates isolated vascular tension; nitrite content of macrophages was measured by Griess assay; MTT assay and FRAP assay was applied for cell viability and total cell antioxidant capacity; auto-nitration of CuZn-SOD was measured by Western blot and colorimetric methods; platelet aggregation was detected by turbidimetry; and aorta ring relaxation was recorded by isolated vascular function experience devices for rats.
RESULTTFAS demonstrated dose dependence (25, 50, 100, 200 mg x L(-1)) on inhibiting induced macrophages NO production from generating, while increasing cell viability and total anti-oxidant capacity. Auto-nitration of CuZn-SOD was suppressed by TFAS in dose dependence (0.5, 5, 50 mg x L(-1)). TFAS showed an inhibitory effect on collagen-induced platelet aggregation at 50 mg x L(-1) and an endothelium-dependent relaxation effect on PE-induced vasoconstriction at 1 g x L(-1).
CONCLUSIONTFAS shows effect on anti-inflammation, anti-oxidation, anti-nitration, anti-platelet aggregation and vasodilatation in experiment in vitro, which may inhibit vascular inflammatory by regulating multiple target points. It is among material bases for promoting blood circulation and removing blood stasis.

OBJECTIVEThis paper aims to assess the interaction between common variations in catalase (CAT) polymorphic gene and environmental factors for antioxidant defense enzyme in modulating individual susceptibility to colorectal cancer (CRC).
METHODSA case-control study with 880 colorectal cancer cases and 848 controls was conducted to investigate whether variations in the catalase (CAT) gene, one of the genes involved in scavenging oxidative stress, influenced susceptibility to CRC.
RESULTSThe interaction between life style and genotypes as well as with their effects on colorectal cancer was deduced from the present study. Significant difference (P = 0.01) was identified in the distribution of CAT genotype between the colorectal cancer cases and the controls. The CRC cases had significantly lower mean activity than the controls (P < 0.01). Correlation analyses revealed statistically significant correlations between CAT activity and CAT genotype (P < 0.01).
CONCLUSIONThe risk of CRC was associated with smoking, low vegetable consumption, high pork and poultry consumptions, and low or high BMI. This is the first study reporting an association of polymorphism CAT-21A > T with colorectal cancer. Low CAT activity was associated with an increased risk of CRC; however, no evidence was found to support an association between CAT-21A > T polymorphism and CRC risk.

OBJECTIVETo compare multiple organ dysfunction score (MODS), the sequential organ failure assessment (SOFA) and the logistic organ dysfunction score (LODS) in predicting hospital mortality in severe sepsis.
METHODSFour hundred and three patients admitted to the ICU from December 2004 to November 2007 with a diagnosis of severe sepsis were enrolled in this study. Their MODS, SOFA, LODS and Acute Physiology and Chronic Health Evaluation (APACHE) II at admission and the highest score during hospitalization were respectively recorded and collected in regard to mortality. The discrimination of three multiple organ dysfunction score systems were assessed by the areas under the receiver operating characteristic curves (AUC).
RESULTSThe AUC of admission scores was 0.811 for LODS, 0.787 for SOFA, 0.725 for MODS, and 0.770 for APACHE II in predicting hospital mortality. All maximum scores had better power of discrimination than the admission scores (P < 0.01). The power of discrimination of LODS and SOFA were better than the MODS, either the admission or the highest, respectively (P < 0.01). However, no significant difference was observed between the LODS and the SOFA regarding mortality prediction (P > 0.05). The AUC value for the APACHE II score was much lower compared to LODS (P < 0.01). However, there was no difference in AUC value among APACHE II, SOFA and MODS (P > 0.05).
CONCLUSIONLODS, SOFA and MODS show a good discrimination power, while maximum LODS is of the highest discrimination power to predict the outcome of patient with severe sepsis.
