摘要
背景:六神丸是传统中药复方,具有清热解毒,散结消肿止痛之功效。现代药理证明六神丸具有抗炎、镇痛、强心、抗病毒、抗肿瘤等作用,临床上常用于各类感染性疾病、恶性肿瘤的治疗。目的:探讨六神丸对食管癌移植瘤的抑瘤作用及对微血管密度、血管内皮生长因子表达的影响。方法:通过复制人食管癌裸鼠移植瘤模型,将48只裸鼠随机分为六神丸高剂量组、六神丸中剂量组、六神丸低剂量组、顺铂组、模型组、空白组,按照给药方案用药。用药20 d后处死动物,称量瘤体质量,计算抑瘤率;免疫组化检测瘤组织微血管密度、血管内皮生长因子的表达。结果与结论:六神丸高、中、低剂量组、顺铂组的移植瘤质量明显低于模型组,差异有显著性意义(P<0.05)。六神丸高、中、低剂量各组移植瘤内微血管密度、血管内皮生长因子的表达明显低于模型组,但没有顺铂组明显。结果表明六神丸对食管癌移植瘤生长有明显抑制作用,通过下调肿瘤组织血管内皮生长因子表达活性、降低微血管密度,可能是六神丸抑瘤作用机制之一。
BACKGROUND：Liushen Pil is a traditional Chinese herbal formula, has the effects of heat-clearing and detoxicating, eliminating stagnation, detumescence and al eviating pain. Modern pharmacology verifies that Liushen Pil has anti-inflammatory, analgesic, cardiac, anti-viral, anti-tumor effects, and has been extensively used in the treatment of various infectious diseases and malignant cancer. OBJECTIVE：To investigate the inhibitory effects of Liushen Pil on esophageal cancer xenografts, and effects on microvessel density and vascular endothelial growth factor expression. METHODS：After reproducing nude mouse models of human esophageal cancer, 48 nude mice were randomly divided into high-dose Liushen Pil group, moderate-dose Liushen Pil group, low-dose Liushen Pil group, cisplatin group, model group and blank group. According to medication regimen, drugs were given. The growth of transplanted tumor of nude mice was dynamical y observed in each group. The nude mice were sacrificed after 20 days of treatment. Neoplasm weight was taken and the tumor-suppressing rate was calculated. Immunohistochemistry was used to detect microvessel density and the expression of vascular endothelial growth factor. RESULTS AND CONCLUSION：The weight of transplanted tumor was significantly lower in the high-dose Liushen Pil group, moderate-dose Liushen Pil group, low-dose Liushen Pil group, and cisplatin group than in the model group （P〈0.05）. Microvessel density and the expression of vascular endothelial growth factor were obviously lower in the each Liushen Pil group than in the model group, but not as apparent as that in the cisplatin group. Results suggested that Liushen Pil can inhibit the growth of the esophageal cancer xenografts. Liushen Pil can down-regulate the expression of vascular endothelial growth factor and reduce microvessel density, which is one of the tumor-inhibiting mechanism of Liushen Pil .
