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。

Since curly leaf hybrid could be recognized at early stage,and displayedobvious dwarfness,choosing"Zha′ai 76"as paternal parent not only raised thehybrid-selecting efficiency from the pollinated progenies,but also raised thebreeding efficiency of apomctc dwarf roostock of apple.

鉴别宽叶型杂种较难、需时较长(2-3年生时)并需与染色体倍性鉴定法相结合，因其形态变化较小而生长势又与平邑甜茶无融合生殖苗无明显差异；鉴别光叶型杂种因父本染色体组的影响加大而从形态上容易些，但也需过氧化物同工酶法或染色体倍性鉴定法相配合；皱叶型杂种因在苗期刚出1-2片真叶时就表现明显的标志性状、能从叶片形态上准确鉴别出来，毋须染色体倍性鉴定等复杂方法；因皱叶型杂种能早期鉴别，又表现明显的矮生性，因而选用"扎矮76"做父本不仅大大提高了平邑甜茶授粉后代中选择杂种的效率，而且提高了苹果无融合生殖型实生矮砧育种的效率。

While many parents and conservative politicians are appalled by graphic images in some sex education textbooks, health experts say teachers need to offer even franker explanations of the risks of unprotected sex.

专家认为，日本青少年性问题的严重化归咎于日本人在家中羞于谈性的传统观念和社会上将少女视为性对象的不良倾向的；同时，网络的普及为网络性交易提供了温床，一些少女就为换取零用钱或礼物与网友发生性行为。

Results Loss or most loss of competence to defense sexual invasion were often observed in youth patients with chronic-he bephrenic type schizophrenia, moderate mental retardation, and in itial hypomania.

目的研究女性精神病人性防卫能力的特点和司法鉴定中应该注意的问题；方法对过去10年间鉴定过的64例案例进行回顾总结；结果性防卫能力丧失最常见于年轻的衰退期青春型精神分裂症病人、中度以上精神发育迟滞病人、首次发病的年轻轻型躁狂症病人，而其他类型的精神病人不容易发生性防卫能力丧失。

Bt cotton and corn may affect natural enemies indirectly by decreasing the population of lepidopteran insects that serve as hosts of parasitoids or predators. Population densities of predators in Bt fields were significantly higher than those in non-Bt fields treated with insecticides for control of target pests.

杀虫剂用量的减少，降低了对天敌的杀伤力，Bt田中捕食性天敌的种类和数量均显著高于常规施药田；但Bt田内靶标害虫数量的减少和质量的降低，在一定程度上影响了寄生性天敌的种类和数量。

In consideration of endogeneity problems, we use the trivariate probit model which estimate three equations- employment, liver disease and drinking . Finally we used WESML (weighted exogeneous sampling maximum likelihood) method to correct the bias caused by choosing specific sample.

其中，我们考量了肝病与饮酒习惯分别对於就业的内生性问题，并且在trivariate probit模型中使用工具变数来得到一致性的估计结果，最后，我们利用WESML (weighted exogeneous sampling maximum likelihood)的估计方式来修正因为选取某特定样本，所造成估计结果缺乏代表性的问题。

In addition, the clinical data of 96 FAP cases clinically diagnosed between 1985 and 2000 were analyzed retrospectively, which included clinical (enteral and apenteric manifestations, methods of diagnosis and screening, surgical modality and follow-up findings).

我们认为结肠镜是FAP最可靠、最有效的临床诊断方法并在家系成员筛选中可发挥重要作用；CHRPE是具有高度特异性和敏感性的辅助诊断方式，可作为对未成年家系成员筛选的首选方法；FAP常伴发上消化道病变包括胃窦部增生性息肉，十二指肠腺瘤发病率高，但癌变少见；腹腔硬纤维瘤是FAP的严重结肠外病变，术后复发率高；FAP术后如直肠粘膜有残留，其腺瘤复发及癌变危险性高，应定期结肠镜随访。

OBJECTIVE:To study the mechanism of hirudin on preventing and curing proliferative vitreoretinopathy,by observing the pathological changes of fundus oculi and eye with ophthalmoscope and light microscope respectively of the experimental traumatic PVR model rabbit and measuring the changes of platelet derived growth factor in corpus vitreum and flash electroretinogram of the model rabbit eye when PVR model rabbit is treated with injection of hirudin into the eye ball.

目的：通过观察水蛭素对实验性外伤性增生性玻璃体视网膜病变中眼底和眼病理的改变以及对血小板源性生长因子和闪光视网膜电图的影响，从而探讨水蛭素防治PVR的作用机制。
