This paper is concerned with the stability of neural networks with time-varying delays. Under assumption that the nonlinear stimulate functions are Lipschitz continuous, by means of generalized Halanay inequalities, Dini＇s derivative and functional analysis techniques, several globally exponential stability criteria are established, which are only dependent on the parameters of the system.

Objective：To obtain early results of off-pump coronarE~ artery bypass grafting（OPCAB） in patients with significant left main coronary artery（LMCA） and triple vessels stenosis by comparing with those of a similar group undergoing conventional coronary artery bypass surgery（CCAB）. Methods：Data for patients with significant LMCA and triple vessels stenosis who underwent CCAB or OPCAB were collected retrospectively between January 1999 and May 2006. Non-randomized, retrospective data analysis included demo- graphic and preoperative risk factors, operative details, clinical outcome and early follow-up. Results： The number of distal anastomo- sis and grafts varied from 3 to 6. The average number per patient was similar in the two groups （OPCAB group：3.76 ± 0.98, CCAB group：3.81 ± 1.02）. Thirty-day mortality occurred to one patient in the OPCAB group whereas two early deaths were observed in the CCAB group but did not reach statistical significance （P 〉 0.05）. The frequency of atrial fibrillation （AF）, IABP usage, mediastinitis, re-operation for bleeding （or tamponade） were similar in the two groups （P 〉 0.05）. Postoperative inotropic requirements, peak CKMB, ventilation time, blood loss, FFP, RBC transfusion need and the length of ICU-stay were all significantly lower in the OPCAB group compared with CCAB group（P 〈 0.05）.Conclusion： Significant LMCA and triple-vessel stenosis can safely and effectively undergo myocardial revascularization using OPCAB surgery. LMCA should no longer be seen as a contraindication to perform OPCAB grafting.

Objective： To Comparatively study grafts flow between on-pump and off-pump coronary bypass surgery for patients with triple coronary artery disease. Methods ： The grafts flow was studied in 100 patients of OPCAB and compared with 100 cases of CCABG by means of Medi-Stim Butterfly Flowmeter measurement intraoperatively. Results： The mean number of the distal anastomosis was 3.78＋ 1.11 in CCABG group, and 3.83 ＋ 0.93 in OPCAB group. The index of completeness of revascularization in CCABG group was 1.01 ＋ 0.08, and 1.10＋ 0.09 in OPCAB group. The flow of grafts was satisfied in all patients. The PI values were all under 5. There was no significant difference in the mean graft flow and PI value between two groups. Conclusion： OPCAB can provide the same grafts flow and similar completeness of revascularization when compared with CCABG which indicates the similar anastomosis quality of grafts in OPCAB and CCABG groups.

　　Triarylamines are an important class of compounds, because they have been used as the hole-transport layer in electroluminescent devices. [1] New palladium catalyzed methods to form arylamines have emerged recently from Hartwing and Bucchwald . [2,3] Our group have investigated unusual diboration of allenes catalyzed by palladium complex and organic iodides. [4] Here we will report that arylamines react with bromoanthrancene (or dibromoanthancene) to afford triarylamines in the presence of Ligand-palladium complex. The structures of products were de termined by 1H NMR, 13C NMR, 13C (DEPT), IR and MS (HREI and EI) spectra.……

This paper presents a class of hybrid one-step methods that are obtained by using Cramer's rule and rational approximations to function exp(q). The algorithms fall into the catalogue of implicit formula, which involves sth order derivative and s+1 free parameters. The order of the algorithms satisfies s+1≤p≤2s+2. The stability of the methods is also studied, necessary and sufficient conditions for A-stability and L-stability are given. In addition, some examples are also given to demonstrate the method presented.

AIM: To study the effect of 5-lipoxygenase inhibitors on the expression of intercellular adhesion molecule-1 (ICAM-1) inmelanoma cells. METHODS: ICAM-1 protein of human melanoma cell a375 was detected by enzyme-linkedimmunosorbent, flow cytometry and Western blot analysis. Level of ICAM-1 mRNA in a375 was evaluated byNorthern blot analysis. Adhesion of a375 to endothelial cell EC304 was analyzed by isotopic tracing. RESULTS:5-Lipoxygenase inhibitors nordihydroguaiaretic acid, AA861 and MK886, could suppress the expression of ICAM-1protein as well as of its mRNA in a375 cells and reduce the adhesion of a375 to EC304. CONCLUSION:5-Lipoxygenase inhibitors can inhibit the expression of ICAM-1 in human melanoma cells and may be valuable fortreatment of melanoma metastasis.
