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 typical manifestations of PHC were nodular,irregular and heterogenous enhanced regions in lesion,tumorous vessels could be seen in the arterial phase,the hyperdense regions in the arterial phases were changed to hpodense quickly in the portal phase;The characteristic findings of HCH were well-defined intense mural nodular enhancement in the arterial phase,and centripetally oriented enlargement of this nodular in the portal phase,the density of the nodular in the arterial phase were similar to that of aorta or hepatic arteries.

原发肝癌的典型表现是动脉期病灶内结节状、片状强化，并可见肿瘤血管影，强化部分在静脉期迅速呈低密度影；肝血管瘤的特征性表现为动脉期病灶边缘结节状强化，密度类似于主动脉或肝动脉，静脉期强化结节逐渐向病灶中央扩展；肝转移癌的主要表现为动、静脉期病灶边缘环状强化，中央部分无明显强化，静脉期还可见到"牛眼征"。

Typical bands were used to analyze relation with ecotypes and characters of fruits, indicating that there was no relation between typical bands and ecotypes, but some extent relation between bands and characters of fruits existed. If all cultivars were divided into freestone and clingstone, melting and nonmelting, both freestone (ratio shared total survey, 41/56=73.2%) and clingstone (ratio shared total survey, 33/79=41.8%) appeared in the loci of S_(167)-1050 bp linked marker raised by Warburton et al. It was apparently not strong linkage between the marker and the character, and exchange rate of genes was high. If combinations of S_(167)-850bp and S_(167)-1050bp or S_(167)-850bp and S_(167)-1400bp were used to distinguish characters of fruits, 6 freestone accessions without clingstone ones and 6 melting accessions without nonmelting ones displayed in the first combination of markers, 20 clingstone accessions and 2 semi-freestone ones without freestone ones appeared in the second combination of markers.

通过典型带对不同生态型、果实性状为类别进行分析，结果未发现有与生态型相吻合的特征带出现，而将供试所有品种按离核、粘核和溶质、不溶质划分归类，供试品种在Warburton等得到S_(167)-1050 bp处粘离核分子标记，出现既有离核(占供试离核41／56=73.2％)，又有粘核(占供试粘核33／79=41.8％)，可见此连锁标记连锁性不强，发生交换的机率较高，而S_(167)-850bp带和S_(167)-1050bp带同时出现时，该组包含6个离核，无粘核品种；6个溶质，而无不溶质。S_(167)-850bp和S_(167)-1400bp同时出现时，包含20个粘核品种和2个半离核品种。

When treated with different concentration of red orpiment(25～200μg/ml)for 16 hours, both NB4 and HL-60 cells showed typical apoptosis features.

The protoliths of the chlorite-actinolite schist were mainly volcanic-sedimentary rocks enriched in basalt. The chlorite-actinolite schist and the altered pillowbasalt are characterized by high contents of TiO5, P2O5 and MgO, LREE-enriched patterns with negative Eu anomalies, and "tumescence" patterns for trace elements with enrichment in Nb, Ta and Ti; these are typical characteristics of "OIB-type" alkaline basalt.

绿泥阳起石片岩的原岩主要为富含玄武岩的火山－沉积岩系，绿泥阳起石片岩和蚀变枕状玄武岩具有TiO2、P2O5、MgO含量较高和LREE富集型、无Eu异常，以及"大隆起"微量元素配分模式和富集Nb、Ta、Ti元素等地球化学特征，显示为较典型的洋岛型碱性玄武岩性质。

The ultrastructure characters of pollen grain in Brassica napus are:1There are vacuoles in cytoplasm but no starch grain in uniceelluar pollengrain.2The veget- ative nucleus of bicellular pollen grain is generally spheroidal;while the generative cell is spinde-shaped,with a big nucleus,thin layer of cytoplasmand few cell orgens,no cell wall.3In three-celled pollen grain the sperm cell is separated from the cytoplasm of vegetative cell by two layers of plasmic membrances.

2The involvement of MFT in woman is more than that in man.(3)The patients showed multiple dome-shaped, skin-colored, firm papules on the face. Some patients also present the lesions on the scalp and neck. No lesion showed the malignant tendency.(4) The histologic findings of MFT are cornified cysts and some nests of basaloid epithelial cells.(5)There were variable clinical expressions in different patients of the same family.(6) Some pedigrees were also affected by feckle or symmetrical progressive erythrokeratoderma, which were not found in MFT patients of other origin.

Dedifferentiated liposarcoma, occurring in up to 10% of well differentiated liposarcoma cases, has similar histologic features to that of undifferentiated high-grade pleomorphic sarcoma; the former develops in a background of atypical lipomatous tumors/well differentiated liposarcoma, whereas the latter shows no specific line of differentiation.
