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。

The high scores of AgNOR and the positive of C-erbB-2 indicates a high degree of malignance of patients with endometrial carcinoma.

AgNOR值增高提示患者可能患有子宫内膜腺癌且提示子宫内膜腺癌恶性程度高，如合并C-erbB-2蛋白的阳性表达率增高可进一步提示患者患有子宫内膜腺癌。

The identified proteins were divided into two following categories: one is regulatory proteins, for example, caffeic acid 3-O-methyltransferas, HSP70, glyoxalase I , actin, and so on. They are involved in protein biosynthesis and processing, cellular structural organization and stress responses. The other is function proteins, for instance, ascorbate peroxidase, cytoplasmic malate dehydrogenase, cytosolic phosphoglycerate kinase, S-adenosyl methionine synthetase, ATP synthase, and so on. They are involved in photosynthesis, photorespiration, redox homeostasis, and metabolisms.

通过分析可以将这些差异蛋白分为两大类：第一类是调节性蛋白，如咖啡酸三氧转甲基酶，热激蛋白70，醛酮变位酶I，肌动蛋白等，它们主要参与蛋白质的合成和加工、胁迫响应、细胞骨架稳定等过程；第二类是功能性蛋白，如抗坏血酸过氧化物酶，细胞质苹果酸脱氢酶，细胞质磷酸甘油酸激酶，S-腺苷蛋氨酸合成酶，ATP合酶等，它们则参与氧化还原平衡、光合作用、光呼吸和各种代谢等过程。

Methods The expression of COX-2 and Survivin of 30 cases of SACC and 20 cases of normal salivary gland was examined with immunohistochemical technique.

采用免疫组织化学检测30例涎腺腺样囊性癌及20例正常涎腺组织中COX-2与Survivin蛋白的表达情况。

The construction of recombinant UNPase provided a basis for the research on biocatalysed synthesis of adenosine. In comparison with uridine, inosine was the better donar of pentose-1-phosphorate. In the reaction mixture composed of 30 mmolL^(-1)inosine, 10 mmolL^(-1) adenine, and 30 mmolL^(-1) pH 7.5 phosphate buffer and 0.5% wet cells gave a high yield of 85.57% at 60℃ in 3h.
