多形性

Microscopically, there are spindle to oblong cells with hyperchromatism and pleomorphism.

显微镜下见深染多形性的梭形或椭圆形细胞。

The nuclei were of low to intermediate nuclear grade with minimal nuclear pleomorphism. Thirteen of 17 cases (76%) were associated with conventional high-grade invasive urothelial carcinoma and 9 cases showed very focal intracytoplasmic vacuoles mimicking signet ring cells.

瘤细胞核的核级为低到中级，伴轻微的多形性。17例中有13例（76%）与常见的高度侵袭性的尿路上皮癌相关；有9例含灶性胞浆内空泡的瘤细胞，类似印戒细胞。

ResultsMorphological features with diagnostic value were established as follows:①Irregular or round-mesh basket type nucleolus;②Malformed nucleus and lobate nucleus with fine bridge;③Perinuclear microfilaments;④Nuclear bodies;⑤Nuclear inclusion bodies;⑥Marked cell pleomorphism arranged irregularly,like a disordered stone pavement;⑦Strange cell and/or giant cancer cell were found;⑧Peculiar papillae or cell clusters were formed;⑨Specific function structure on the surface of cell differentiated poorly.

结果 确定了具有诊断意义的形态学特征：①不规则奇形核仁或网孔状核仁；②畸形核，分叶核伴细桥－核间桥形成；③核旁微丝；④核体；⑤核包涵体；⑥细胞重度多形性，排列紊乱，似乱石铺堆；⑦出现奇形细胞和/或癌巨细胞；⑧形成奇形乳头和奇形细胞簇；⑨细胞表面特异功能结构分化不良。

The mice inoculated with Coxiella burnetii intrana- sally developed interstitial pneumonia,while the primary pathological changes of mice inoculated intraperitoneally are granulomas in spleen and liver.2.The pathological changes became more severe followed the dosage increasing.3.Coxiella burnetii can be detected in spleen and liver at day 2 after inoculation.the lesion became more and more serious from day 2 to day 12.The characteristic changes were observed at day 7,and recovered at day 14. 4.The reticuloendothelial system are main target of Coxiella burnetii.The pathogen was detected in cytoplasm of monocyte -macrophages of spleen, liver, lung, and endothelioid cells of blood vessel. 5. Coxiella burnetii can be found in macrophages lysosomes by electron microscopy. Most of them are round or rod, and polymorphic shape can also be observed in different size.

结果：1、通过不同感染途径的实验证实，滴鼻感染的小鼠主要表现为间质性肺炎，而腹腔注射感染小鼠则以脾脏、肝脏肉芽肿为主要病变。2、通过不同剂量的感染实验发现，随着感染Q热立克次体剂量的加大，动物病变愈加严重。3、通过感染后不同时间的动态病理学观察发现，在腹腔注射后第2d的脾和肝脏即可发现病原体，主要脏器的病理变化从第2d到第12d逐渐加重，第7d动物的病变最典型，至感染后14d动物的受损器官已开始出现修复性变化。4、 Q热立克次体主要侵害机体的网状内皮系统，在感染小鼠的肝、脾、肺和外周血管单核巨噬细胞以及血管内皮细胞胞浆中查见病原体。5、透射电镜观察可见Q热立克次体主要位于巨噬细胞吞噬溶酶体内，呈多形性，多见圆形和杆状，大小不一。

Among these patients, nearly 1/3 displayed various skin lesions at the onset; simultaneous erythematous papules and plaques are the most common initial manifestation.

在所分析的病例中，近1/3大疱性类天疱疮患者初发表现为多形性，以同时出现红斑、丘疹/斑块多见。关键词：类天疱疮，大疱性初发皮疹临床分析

The results of respiratory mechanics, homodynamic mechanics,aterial blood gaS, and inflaInInatory factors [TNF- Q, IL-l fl, IL-6,IL-l0, and adrenomedulin] which detected in animal serumand bronchial alveolar lavage fluid obtained from tiP lObe,heart lobe, and diaPhragIn lobe of right lung seParate1y in the mongreldogs were measured before and after lung injury (including receivinglung protective ventilation).

本实验证明了 loS肺内／肺外不同源性 ARDS动物模型的差异性，而且AnDS的肺部病变存在不均一性和多形性的特点，对有关ARDS进行性低氧血症的发生机制提出了肺动静脉可能存在类似于右一左分流的肺内分流现象，以及因肺内分流而导致严重通气／血流比例失调的解释。发现小潮气十PEEP通气对肺内源性 ARDS疗效不佳，而俯卧位＋小潮气－I－ PEEP通气对肺内／肺外不同源性ARDS均有较好的疗效。。

Results: the findings on ct and mri were as follows: 57 cases of oligodendroglioma, 15 cases of ganglioglioma , 5 cases of dysembryoplastic neuroepithelial tumor , 3 cases of pleomorphic xanthoastrocytoma .conclusion:the images on ct and mri of cerebra peripheral tumor occur some characters , so ct and mri were certain worth on the diagnose and differentiate diagnose of cerebra peripheral tumor.

结果：少枝胶质瘤47例，间变性少枝胶质瘤10例，节细胞胶质瘤15例，胚胎发育不良性神经上皮瘤5例，多形黄色细胞瘤3例。结论：脑浅表肿瘤存在影像特征，ct及mri对其诊断有一定的价值。少枝胶质细胞瘤；节细胞肿瘤；胚胎发育不良性神经上皮瘤；多形性黄色星形细胞瘤；ct；mri

Skin manifestations of leukemia are varied and include leukemia cutis (direct cutaneous infiltration by leukemic cells), Sweet's syndrome, erythema multiforme, erythema nodosum, pyoderma gangrenosum, and bullous pemphigoid.

白血病的皮肤表现比较多样，包括皮肤白血病（白血病细胞直接渗入皮下）、斯威特氏综合征、多形性红斑、结节性红斑、坏疽性脓皮症以及大疱性类天疱疮。

Two pathways may belong to the same functional system, though they have some architectural difference. It has been disscussed that some neural structures in the visceral afferent pathway may have some relation to the somesthetic afferent.

在梭形细胞的树突上见到较多的对称性突触，突触前末梢含有多形性囊泡；在卵圆形细胞的远核区和树突上，常见到含圆形囊泡的末梢，与胞体和树突形成不对称性突触。

Before typical bullae appeared, patients presented with erythema, papules, papulovesicles, plaques, wheals, nodules, or erythema multiforme-like lesions, with the most common lesions being erythematous papules and plaques （occurring in 35.29% of these patients）.

在出现典型的水疱之前，表现为红斑、丘疹、丘疱疹、斑块、风团、结节、多形红斑样皮疹等多形性表现，以同时出现红斑、丘疹/斑块（占35.29%）为多见。

The X-ray diffract was used to analyze the crystal structure of the composite. Results show that after the talc was treated with blend coupling agent, the crystal structure of talc changed, and effect Intercalation phenomenon.

通过X射线衍射分析可知，用混合偶联剂对滑石粉进行预处理后，滑石粉晶体结构发生改变，产生了插层现象，使PP／滑石粉复合材料为纳米复合材料。
