However, at the beginning of PVR process, stimulated and activated by the initiative factors, RPE begin to dislocate from Bruchs membrane , migrate, proliferate, dedifferentiate, transdifferentiate and secrete provisinal extracellular matrix proteins, followed by membrane formation and contraction on both surfaces of the neuroretina and in the vitreous body, resulted in tractional retinal detachment.

PVR发生后，RPE受到始动因素的刺激，开始活化，脱离原位，去分化，移行、增生、发生表型转化等，并分泌细胞外基质(extracellular matrix， ECM)，最终在视网膜前后表面和玻璃体内形成具有收缩能力的增生膜，造成牵拉性视网膜脱离。

It is well known that retinal pigment epithelial cells are predominant proliferative cells in PVR which is an excessively wound healing response occurring after RPE cell wounding. The activated RPE cells migrate from their normal, sessile state to vitreous and onto both surfaces of the retina, in which they begin to dedifferentiate, migrate, proliferate, change phenotype and secrete ECM.

既往研究证明视网膜色素上皮(retinal pigmentepithelial，RPE)细胞是参与PVR的主要细胞，PVR是视网膜脱离后RPE细胞损伤的一种自我修复过程，是一种过度的眼内创伤修复反应；RPE细胞在正常位置上处于静止状态，而在某些病理条件下，如视网膜裂孔形成和视网膜脱离后，RPE细胞脱离原位，开始去分化、移行、增生、发生表型转化并分泌胶原等ECM，最终在视网膜前后表面和玻璃体内形成具有收缩能力的增生膜，造成牵拉性视网膜脱离。

A total of 150 mesenchymal neoplasms of the GI tract, abdominal cavity, and retroperitoneum were retrieved from consult and surgical pathology archives, including 54 GISTs (8 KIT-negative; 13 desmin-positive), 17 GI leiomyosarcomas, 11 GI mural leiomyomas, 13 leiomyomas of the muscularis mucosae, 12 gastric schwannomas, 15 inflammatory myofibroblastic tumors, 9 cases of mesenteric desmoid fibromatosis, 10 dedifferentiated liposarcomas, and 9 malignant peripheral nerve sheath tumors.

我们从会诊病例及活检病例中找出150例间叶性肿瘤（来自胃肠道、腹腔和后腹膜），其中包括54例GISTs（8例KIT阴性、13例desmin阳性）、17例GI道平滑肌肉瘤、11例GI道肌壁间平滑肌瘤、13例GI道粘膜肌层平滑肌瘤、12例胃的神经鞘瘤、15例炎性肌纤维母细胞瘤、9例肠系膜韧带样纤维瘤、10例去分化型脂肪肉瘤和9例恶性外周神经鞘膜瘤。

None of the GISTs, desmoid tumors, inflammatory myofibroblastic tumors, schwannomas, dedifferentiated liposarcomas, or malignant peripheral nerve sheath tumors showed cytoplasmic reactivity for smoothelin.

所有GISTs、韧带样纤维瘤、炎性肌纤维母细胞瘤、神经鞘瘤、去分化脂肪肉瘤和恶性外周神经鞘膜瘤病例的瘤细胞浆均不表达smoothelin。

a three steps sequence therapy was designed for patients suffered post dural puncture headache total 45 cases:step one,patient keep supine recumbence,and intravenous injection of ringer's solution 1000ml with intramuscular injection of tramadol 100mg was administrated. if pdph could not relieve within 24hr,the next step should be use. step two,drinking a cup of coffee three times a day for patients who were allowed to eating or intravenous injection ketamine 0.5mg/kg for patient in fasting diet.

选择椎管内麻醉后发生头痛的病例共45例，按设定的序贯疗法分别为a：去枕平卧1d，每天补液量增加1000ml平衡液，肌注曲马多100mg，无效时进入b和c；b：能进食者给予市售咖啡饮品，每天三次；c：不能进食者静脉注射氯胺酮0.5mg/kg，连用2d；以上治疗无效时进入d：行硬膜外填充自体血10ml。

No matter what kinds of sarcomatous elements are found in a retroperitoneal dedifferentiated liposarcoma, its clinical behavior is not the same as high grade fibrosarcomas, leiomyosarcomas, osteosarcomas, chondrosarcomas, rhabdomyosarcomas, or MPNST.

无论在腹膜后去分化型脂肪肉瘤中发现何种类型的其他肉瘤成分，它的临床行为都与高级别纤维肉瘤、平滑肌肉瘤、骨肉瘤、软骨肉瘤、或恶性外周神经鞘膜瘤不同。

Using sodium silicate solution as the binder of zinc-rich coating ,zinc powder as the filler,distilled water as the solvent,and adding thicker,solidifier,sodium silicate inorganic zinc-rich coating s were prepared.

以硅酸钠溶液为成膜基料，锌粉为颜填料，去离子水为溶剂，加入增稠剂，固化剂等助剂，制备钠水玻璃富锌涂料；应用红外光谱分析、流变学测量和耐液性观察，研究钠水玻璃富锌涂料的固化机理。

The HUVECs retained spindled shaped or cobblestone appearance and positively stained by anti-CD31. DAPI staining showed that 90％of scaffolds surface was reendothelialized and endothelial cells were distributed evently on the surface forming a confluent monolayer.

脱细胞支架细胞成分完全脱去，胞外基质保存完好；分离的细胞培养一周后，细胞呈梭形或多角形，核仁清晰，大小均匀，呈典型的铺路石样；免疫荧光检测可见细胞胞浆内有颗粒状红色阳性信号，说明Ⅷ因子相关抗原染色阳性；膜表面有蓝色阳性信号，说明CD31抗原染色阳性。

RT-PCR show an increase expression of mRNA of MMP-1, MMP-3 and IL-1β in OA synovia tissue in ovariectomized rabbits. Estrogen supplement could decrease the expression, an enhancement effect could observed with progestin.

RT-PCR法半定量检测结果发现，去势后兔膝OA滑膜组织中MMP-1、MMP-3和IL-1β mRNA表达增加，给予雌激素对三者的表达均有抑制作用，加用孕激素可使这一抑制作用增强。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
