Methods The expressions of survivin albumen in 50 cases of gastric cancer and 20 normal people were detected immunohistochemistry method and its relation with the clinical-pathological parameters of gastric cancer was analyzed.

One hand mechanical obstruct led to the increase of veinous resistance and the obstacle of microcirculation, the other hand the adhesive PMN was activated in excess, the white blood cells released a lot of enzymes, in which PMN-elastase can decompose the components of cell and many albumens, inclusive of immunoglobulin、alexin and fibrication. These components induced the injury of the pancreatic capillary vessels and cell and lysosome enzy made the tissue protein hydrolyze and produced unsaturated fatty acids, which destroyed the structure and function of cellar membrane. The inflammatory cellar factors activate other immunocytes to produce the injury and necrosis of tissue, which aggravated the pathological injury and led to shock、pyaemia and MODS. So ICAM-1 and LFA-1 played an important role in SAP. Frossard found that the expression of ICAM-1 in the rat model, especially in serum、pancreas and lung. All these showed ICAM-1 is an important factor in AP and concomitant lung injury.

胰腺小叶组织局部血管EC首先被激活，ICAM-1表达升高，与被激活的PMN表面表达的LFA-1相结合，"PMN-EC"相互作用加剧，一方面机械性阻塞毛细血管导致静脉阻力增加、微循环障碍；另一方面粘附的PMN过度吞噬或激活，当白细胞吞噬的颗粒不能被封闭隔离，连同细胞内的酶被释放出来，其中的PMN-elastase能够降解细胞基质中各种成分，水解多种蛋白，加重胰腺的毛细血管内皮细胞和腺泡的损伤；释放的溶酶体酶使组织蛋白水解，产生的不饱和脂肪酸引发脂质过氧化方应，破坏细胞膜的结构和功能；释放的炎性细胞因子，激发其他的免疫细胞的功能，导致进一步的组织损伤和坏死，加重SAP的病理损伤，最终导致休克、脓毒血症及多器官功能障碍等严重后果。

Abstract］ objective to study the pathological features and histopathological type and differential diagnosis of hepatic focal nodular hyperplasia.methods the clinicopathological characteristics of 40 cases of fnh were studied.all were evaluted by use of paraffin embedded sections and he staining before light microcope observation.results there were 28 females and 12 males fnh patients whose age were from 16 to 62 years（median 41.3）,all alpha-fetoprotein was negative and had no hepatitis history.25 cases were classic type showed characteristic central stellate fibrotic scar,composed of fibrous connestive tissue and tortuous blood vessels.8 cases were telangiectic type,the left were mixed type and adenomatoid type.conclusion fnh is a reactive proliferation of hepatic cells to local blood vessel anomalies,it is not realy a tumor.its differential diagnosis includes hepatic adenomatous hyperplasia nodule,hepatic anaplasia nodular hyperplasia,fibrolamellar hepatocellular carcinoma and hepatocellular adenoma.

目的 探讨肝局灶性结节性增生的病理形态特点、组织分型及鉴别诊断。方法分析40例肝局灶性结节性增生的临床资料，并采用石蜡包埋he染色光镜下观察其组织学特点。结果 40例肝局灶性结节性增生患者中，女28例，男12例，年龄18~62岁，平均年龄41.3岁，所有病例术前均无肝炎病史，甲胎蛋白阴性，组织学上25例为经典型，有特征性的中央纤维瘢痕，由纤维结缔组织及扭曲血管组成。8例为毛细血管扩张型，其余为混合型及腺瘤样增生型。结论肝结节性增生是一种肝细胞对局部血管的异常反应性增生，并非真性肿瘤，主要与肝腺瘤样增生性结节、肝间变性结节状增生、肝纤维板层癌及肝细胞腺瘤鉴别。
