Veterinary Dermatology, Volume 36, Issue 6, Page 862-869, December 2025.ABSTRACT Background Chronic cases of canine otitis externa (OE) often develop infections with Pseudomonas aeruginosa (PA). Given the organism's high level of resistance, veterinary surgeons often turn to compounded solutions. Limited data describing the stability and potency of compounded ceftazidime (CAZ) solutions are available, which may affect ...

超声介导微泡破裂法对VEGF体外转染成纤维细胞蛋白表达影响的实验研究
Zhongguo shiyan zhenduanxue, 2008 目的利用ELISA检测法观察诊断剂量的超声介导微泡破裂法对VEGF体外转染成纤维细胞蛋白表达的影响并探讨该种转染方法的最佳超声条件。方法实验分组:单纯VEGF质粒转染组;超声+造影剂微泡+VEGF质粒转染组,该组并根据MI（机械指数）分为三组1.2;1.4;1.6。转染后利用ELISA法对各组成纤维细胞的VEGF蛋白表达进行定量检测;利用锥虫蓝染色法比较不同超声强度对细胞活性的影响。结果VEGF质粒转染成纤维细胞后,24h开始即有较高水平的VEGF蛋白表达,表达量于48 h7、2 h呈下降趋势;超声 ...

TIPE expression in gastric cancer and its clinical significance [PDF]
, 2015 背景及意义：胃癌是严重危害人类健康的最常见的恶性肿瘤之一，发病率位居所有恶性肿瘤的第二位，死亡率列所有恶性肿瘤的第三位，目前临床上大多数患者确诊胃癌时已是中晚期，根治性手术仍然是胃癌的主要治疗方式，也是唯一有希望治愈胃癌的手段，但手术效果不佳，直接影响愈后。因此深入研究胃癌发生、发展的分子机制，可为胃癌早期诊断提供依据，同时也为临床治疗提供有效的靶点治疗，具有重要的临床意义。肿瘤坏死因子α诱导蛋白8（Tumornecrosisfactor-αinducedprotein-8，TIPE，TNFAIP8 ...

Hydrocortisone Aceponate for Chronic Otitis: Long‐Term Efficacy
Veterinary Dermatology, Volume 36, Issue 6, Page 870-878, December 2025.Effective management of otitis externa (OE) requires addressing all contributing factors to prevent chronicity and recurrence. Evidence on the long‐term efficacy of topical corticosteroids in preventing recurrence and secondary infections remains limited. This retrospective noncontrolled study evaluated the efficacy of hydrocortisone aceponate (HCA) in
