In both clinical and animal experiments,it has been confirmed that the inflammation in brain is involved in the development of brain damage after the ischemia.However,the pro-inflammatory mechanism is extremely complicated.Recently,a growing number of reports indicates that many factors play their roles in the inflammation,such as leukocyte,interleukin-1?(IL-1?),tumor necrosis factor(TNF)and mast cells.They are released/presented in the region of cerebral ischemia and include both ischemic and secondary brain injury.

Objective To develop a real-time quantitative PCR(RQ-PCR) assay based on TaqMan technology for rapid detection and quantification of tick-born encephalitis virus (TBEV) RNA. Methods According to all the TBEV genome sequences in GenBank, RQ-PCR primers and probes were designed in the conservative regions of TBEV C gene and NS5 gene. In addition, primers for conventional PCR were designed using E gene as target. The detective system was established and validated by using TBEV MDJ01 strain. In order to examine the specificity of the system, other viruses of flavivirus were assayed with the RQ-PCR simultaneously. The TBEV standard curve was drawn respectively by measuring TCID_ 50 titre and copy number. The sensitivity of RQ-PCR and the conventional PCR assays were compared, and TBEV infected mice model was reproduced for evaluation. Results The sensitivity of RQ-PCR assay was 100copies/reaction or 1 TCID_ 50 , which was 10 fold higher than conventional PCR. The results were all negative when used to detect other flavivirus including the yellow fever virus, dengue virus type 1, 2, 3 and 4, Japanese encephalitis virus, West Nile virus. The coefficient of variability was less than 5% from inter- and intra-assay showing that both the repeatability and stability of the system were good. Conclusion A sensitive, specific and convenient RQ-PCR method has been established, which is valuable for early detection of TBEV.

Objective To assess the efficacy and safety of two kinds of arterial suture-mediated closure devices (Angioseal and Perclose) in patients after coronary arteriography(CAG) and percutaneous coronary intervention (PCI). Methods 1?020 patients (672 male, 348 female, mean age 57.8?2.4 yr) undergoing CAG or PCI were randomized into either the Angioseal group (CAG 380, PCI 120) or the Perclose group (CAG 392, PCI 128). The procedural success rate and occurance of local complications were compared between the two groups. Results Both kinds of devices had a high success rate (Angioseal 94% vs Perclose 96%) and there was no statistical difference between them. There were five cases of hematoma and no pseudoaneurysm in the Angioseal group. On the other hand, there were four cases of hematoma and three cases of pseudoaneurysm in preclose group. There was no statistal difference in terms of local complications between the 2 groups. Conclusion Both kinds of arterial suture-mediated closure devices (Angioseal and Perclose) are feasible and safe for patients undergoing CAG and PCI.

s:Objective To study the effective ingredients of Shuangshenningxin Fang (SSNX). Methods Based on analyzing the HPLC fingerprints of rat samples obtained after orally taking SSNX, the ingredients absorbed into blood were identified. The cultured cells were subject to hypoxia and reoxygenation. The leakage of lactic dehydrogenase (LDH) from cardiomyocytes was measured. Results Fifteen ingredients were detected after oral administration of SSNX. Dl-tetarhydropalmatine (Dl-THP), salvianolic acid B (Sal B), ginsenosides (Rg1) and dehydeocorydaline (DHC) were identified. Rg1 and DHC reduced the LDH leakage (P

Objective To investigate the effect of tirofiban on myocardial necrosis biomarker after percutaneous coronary interventions(PCI)in patients with aspirin resistance(AR).Methods 374 consecutive patients with aspirin 100 mg≥1 week,receiving no other antiplatelet therapy,scheduled for PCI were enrolled.all patients were given an loading dose of 300 mg clopidogrel at least 12 hours before PCI and an 75 mg maintenance dose per day.Patients were randomized into tirofiban group(n=38)and control group(n=45)after PCI.The levels of CKMB,TnI at 8,12,and 24 hours after PCI were measured in all patients;if the CK-MB,TnI value was above normal upper limitation,it was considered elevated.Results 83 patients were AR(22.2%)and 54.2%of them are females.The frequencies of CK-MB elevation were 15(39.5%)in tirofiban group and 19(42.2%)in control group,and TnI elevation was 18(47.4%)and 23(51.1%)in the two groups respectively.Conclusion Tirofiban can not decrease the elevation level of CK-MB and TnI in patients with AR after PCI.

Objective:To investigate the significance of metronomic therapy against Helicobacter pylori (HP) in the prevention of delayed emesis caused by chemotherapy of gastric cancer compared with the routine therapy. Methods:HP infection was confirmed by carbon 14 breath test in 69 patients. Combined chemotherapy was employed for the first time in the patients, who were divided into groups A and B. Metronomic therapy was administered to group A (n=33). Briefly, triplex medication against Helicobacter bacil i triplex was oral y ad-ministered:20 mg of omeprazole and 0.5 g of amoxicillin twice daily, with 200 mg of tinidazole once daily. Oral administration in group A was performed for 14 days from the start of chemotherapy. Simultaneously, 5-HT3 antagonists were applied. By contrast, group B (n=36) was treated with the oral triplex medication against Helicobacter bacilli:20 mg of omeprazole and 1 g of amoxicillin twice daily, with 400 mg of tinidazole once daily. Oral administration in group B was performed for 7 days from the beginning of chemotherapy with simultaneous application of 5-HT3 antagonists. Both groups were simultaneously treated with the 5-HT3 antagonist granisetron at 3 mg once daily during the administration of anti-HP therapy. HP infection was evaluated by immunohistochemistry before and after treatment. Results:The total effective rate for emesis in group A was 84.85%, which was significantly higher than that in group B (55.56%). Among the patients in group A, 15.15%demonstrated delayed emesis, compared with 44.44%of the patients in group B;the number of individuals was significantly lower in group A than in group B. The average number of chemotherapy cycles in group A was significantly higher than that in group B at 3.1 cycles;the difference between groups was statistically significant (P<0.05). In addition, the HP infection in group B was significantly lower than that in group A (P<0.05). Conclusion:Compared with one week of treatment with the conventional dose, two weeks of low-dose metronomic therapy against HP during chemotherapy can significantly reduce chemotherapy induced delayed emesis and can significantly reduce the degree of HP infection in patients with gastric cancer with HP infection.
