这篇安全新闻结论指出，一如蛋白质产品，这3种TNF-alpha拮抗剂潜在致免疫性，且会促使免疫调节严重皮肤反应，如EM、SJS和/或TEN；评估TNF-alpha拮抗剂和严重皮肤反应之间的关联，可能会因为一些共同因子而造成挑战，例如同时服用的1种或多种药物与EM、SJS和/或TEN的关联，当接受TNF-alpha拮抗剂治疗时发生任何的严重皮肤反应须有适当的诊断和治疗，以及考量替代治疗。

Results All17patients had reiteratively blood in stools.The longest medical history of these patients is of3years,the shortest is of2months.8cases showed symptoms of stomachaches;2cases showed symptoms of peritonitis.3cases resulted in positive tests in the radioactive scanning.Of the rest of the patients,1case showeda positive test in the selective arterial angiographies.Of the17patients,12recovered completely after the operation.And no recurrence was found in the following3～5years.5patients died of the recurrence of tumor and metastasis.

In this study, samples were taken during the period November 2005 to March 2007. Of total of 1109 dogs sampled, 168 Salmonella spp. were isolated, 16.0% were positive for Salmonella spp. of stray dogs; 7.4% of household dogs were positive for salmonellae. Salmonella Newport (16.7%) and Enteritids (10.7%) was the most prevalent serotype. Additionally, the result of antimicrobial susceptibility test showed that 99.4% of isolated strains (167/168) were resist to one or more than one antibiotic.
