Results The supratentorial lesions involved the occipital lobe in 4, frontal lobe in 3, fronto-occipital lobe in 2, temporo-occipital lobe in 3, lateral ventricle in 1 case and the saddle region in 1. All the lesions were large in volume and most of them presented heterogeneous signals in MRI. Of the 14 cases, 12 showed cystic degeneration and necrosis, 2 had hemorrhage and 6 showed signs of emptied small blood vessels. Twelve cases had heterogeneous enhancement and 2 had moderate enhancement. Pathologically, 10 cases of neuroblastomas were identified, along with 3 ganglioneuroblastomas and 1 atypical rhabdoid tumor.

结果 病灶位于顶叶4例，额叶3例，枕顶叶2例，颞枕叶3例，侧脑室1例，鞍区1例，病灶普遍较大，病灶绝大多数信号不均匀，病灶内可见囊变／坏死（12例）、出血（2例）、流空小血管影（6例），增强后病灶呈明显不均匀强化（12例），中等强化2例；神经母细胞瘤10例，节细胞神经母细胞瘤3例，非典型横纹肌样瘤1例。

Three-dimensional Matrigel constructs contained aleolar forming units comprised of cells displaying AE2 cellular ultrastructure while expressing the SpC gene and gene product. The addition of tissue-specific growth factors induced formation of branching, sacculated epithelial structures reminiscent of the distal lung architecture.

通过对细胞亚微结构的观察和对SpC基因及其表达产物的分析，研究者发现培养体系中肺组织形成单位中具有能向肺泡II型上皮细胞分化的细胞；而通过添加组织特异性的生长因子，他们还发现这一做法会促进培养组织形成具有分支和囊状上皮结构的类似终末肺泡组织的形态结构。

Methods The cells of LLC-PK1,Hela,Caki-1,T24 and fibroblast were incubated on 96-w ell plate with addition of diffe-rent concentration of cystic fluid of ACDK and t hat of simple renal cyst. After 24 hours for reaction, MTT method was used to de termine and compare the proliferative activity of 5 cell lines.

将LLC-PK1， Hela， T24， Caki-1和成纤维细胞接种于96孔培养板中，经过24h培养，加入不同浓度的ACDK和单纯肾囊肿的囊内液作用24h，用MTT法测定培养细胞的增殖活性，比较两者之间对细胞增殖的抑制作用。

Objective To investigate the mechanisms of hair cell generation and regeneration, a primary culture system of utricular sensory epithelial cells of the rat was established.

目的 建立大鼠椭圆囊感觉上皮细胞( utricular sensory epithelial cell， USEC )的原代培养体系，为研究毛细胞再生机制提供大量来源一致的细胞。

The results showed that the expression of calm3 and trm112l genes had no remarkable differences in oocytes and 8-cells stage embryos, but were significantly different in blastocysts. It was supposed that these two genes were possibly maternal genes, and they might be involved in oocyte maturation and zygotic genome activation.

结果显示，在卵母细胞和8细胞期胚胎，基因calm3和trm112l的表达量无显著性差异，而在囊胚期的表达量与前两个时期的表达量存在显著性差异，推测这两个基因在牛胚胎发育过程中的表达可能属于母型调控，提示该基因在卵母细胞成熟和合子基因激活中起一定作用。

RESULTS: The encysted larvae of albendazole treated group became significantly damaged,most worms were shrunken and surrounded by inflammatory cells.

结果：阿苯达唑治疗组，囊包幼虫的结构明显破坏，虫体缩小与断裂，部分虫体被吸收，囊包内伴有炎细胞浸润。

To explore the existence and dynamic changes of the Golgi body-like structure in the log-phase and encysting trophozoites (6, 12, 18 hours) of Giardia lamblia, these trophozoites were stained with C6-NBD ceramide, a specific marker for Golgi body in eukaryotic cells, and then they were observed with fluorescence microscopy.

目的 探讨类高尔基体结构在蓝氏贾第鞭毛虫滋养体和成囊不同时段的存在情况及其动态变化机理。方法用可特异性标记真核细胞高尔基体的荧光染料C6-NBD神经酰胺，标记有活性的蓝氏贾第鞭毛虫滋养体及成囊6、12、18h虫体，并用荧光显微镜观察。

A quantitative assay of OM and M in biological specimen was established on their characteristics Everted gut sac and Caco-2 cell model were used to study the intestinal absorption kinetics of OM and M.

通过大鼠外翻肠囊和Caco-2细胞这两种肠吸收模型对OM和M的肠吸收特征及吸收动力学进行了研究，两种方法都显示OM的肠吸收主要为经细胞旁路被动扩散吸收，而M的肠吸收主要为经细胞通路被动扩散吸收。

In ovariectomy group, ovaries on both sides were extirpated at sterile. In implantation group, the APA-microencapsulated ovarian cells were implanted into abdomen of the ovariectomized rats. In estrogen replacement therapy group, diethylstilbestrol was injected into abdomen of ovariectomized rats (0.2 mg/kg/3 d).

将40只雌性Wistar大鼠随机分为4组：去势组于无菌条件下切除双侧卵巢；微囊移植组手术摘除双侧卵巢后腹腔移植包裹卵巢细胞的海藻酸钠-多聚赖氨酸-海藻酸钠微囊；雌激素替代治疗组手术摘除双侧卵巢后腹腔注射乙烯雌酚 0.2 mg/kg，每3 d注射1次。

Basaloid squamous cell carcinoma of the esophagus is rare, historically confused for adenoid cystic carcinoma, and recently shown to behave similar to conventional, keratinizing esophageal squamous cell carcinoma.

食管基底细胞样鳞状细胞癌罕见，组织学上易与腺样囊性癌相混淆。最近有研究表明，食管BSCC生物学行为类似普通角化型食管鳞状细胞癌。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
