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 objective of the present study is to explore the effect of inhibition of ERK on arsenic trioxide - induced apoptosis in gastric cancer cell line.

本研究的目的是通过检测抑制ERK对As_2O_3诱导的胃癌细胞凋亡有无影响，探讨ERK在As_2O_3诱导胃癌细胞凋亡的信号转导途径中的作用。

Recent studies found that ischemic brain damage is resulted from many reasons such as functional rearrangement of glia cells, an ion balance disorder, lipide peroxidation induced by free radicals, and changes of neurotransmitters.

许多继发性因素，如缺血后神经胶质细胞功能的重新安排，离子平衡紊乱，自由基引起的脂质过氧化损伤，以及神经递质的改变等可诱导神经细胞死亡，继而导致脑损伤，但有关缺血性细胞死亡机制目前还无定论。

Mutant mice than in wild-type controls, and tetrodotoxin or bicuculline application abolished the difference between the genotypes. Studies on human oligodendroglioma cells revealed that GABA played a protective role on Ca〓 overload induced by OGD or glutamate and phaclofen, GABA〓 receptor antagonist, could significantly block the protection.

结果表明：①电凝大脑中动脉后Ca〓2.3-／-鼠脑梗死率和缺血后运动障碍明显重于Ca〓2.3+／+鼠；②Ca〓2.3-／-鼠海马脑片CA1区缺氧后钙超载明显高于Ca〓2.3+／+鼠；③Na〓通道阻滞剂TTX和GABA〓受体阻断剂bicuculline可显著缩小遗传表型之间的差异；④GABA对缺氧无糖及谷氨酸所致的人胶质细胞瘤细胞Ca〓超载有明显的保护作用，此作用可被GABA〓受体阻断剂phaclofen拮抗。

According to the Wakitanis standard, the group A has the best plerosis effect on the repairing of articular cartilage defect compared with the other groups. It had been proved to have the significantly difference from all the control groups by statistics disposal.

Histological observation showed that normal structure was observed in all the groups before being harvested or after being preserved for 30 minutes. However, the more severe structure damage was observed in HPCs or hepatic sinusoidal cells with the more prolonged rewarm ischemia.

形态学观察发现，四组供肝于离体前及低温保存30分钟时的组织结构均无明显异常改变；而在复温缺血期间，各组供肝肝实质细胞及肝窦内皮细胞则表现有不同程度的结构损伤，且在程度上也与复温缺血时间呈明显的平行关系。

Thirty-seven of 38 patients with follow-up are alive without disease and 1 is alive with disease (median 59 mo follow-up duration, range: 8 to 108 mo). Six cases showed myxoid liposarcoma with spindled growth (spindle cell myxoid liposarcoma); these arose in 5 females and 1 male (median age 14 y) and involved the thigh in 40% of cases.

随访的38例都存活，其中37例无再发，1例伴病（随访中位时间为59个月，范围：8至108个月）。6例黏液样脂肪肉瘤的瘤细胞生长方式为梭形（梭形细胞黏液样脂肪肉瘤），患者为5名女性、1名男性（中位年龄14岁），40%病例的肿瘤发生于大腿。

Histological observation was done under phase contrast microscope and scanning electron microscope respectively....

结论SIS的细胞相容性良好，不影响BMSCs的形态，对细胞生长和功能表达无抑制作用，可以用作骨组织工程的支架材料。

The results showed that the number of BrdU-positive cells of the malnourished immature rats was significantly bigger than that of the well-nourished age-matched control rats in the dentate gyrus but not in the subventricular zone.

结果表明，营养不良幼鼠齿状回的细胞增殖和神经生发明显高于营养良好的幼鼠而脑室下层的细胞增殖数量在两者却无明显差异。

BACKGROUND: Studies demonstrated that incisor continuously growing is due to lack of epithelial root sheath formation. However, researches regarding whether receptor activator of nuclear factor κB ligand and osteoclast has correlation with continue root development is poorly understood.

背景：研究表明小鼠不断生长的切牙是由于切牙仅有颈环而无上皮根鞘的形成，但是破骨细胞分化因子核因子κB受体活化剂配体和破骨细胞与不断生长的牙根发育是否相关，目前研究较少。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.
