According to pathological examinations, 6 of 18 cases were with meningiomas, 6 with metastatic tumors, 4 with inflammatory granuloma, 1 with cavernous angioma, and 1 with glioma.

本组18例病理结果：脑膜瘤6例，转移瘤6例，炎性肉芽肿4例，海绵状血管瘤1例，胶质瘤1例。术后神经功能保护良好，无手术并发症及死亡。

The nerve need not be present throughout the entire period of regeneration; once the limb has begun to grow and tissues are sufficiently differentiated, the nerve may be removed without impariment of the morphegenetic potency acquired by these tissues during their earliest stage of formation. Singer (1974) has shown that it does not matter for regeneration what type of nerve, whether motor, sensory, or autonomic, is present in the blastema.

但是再生的肋骨市是「不完全发育」，神经不会在整个再生过程中呈现出来；一旦，肋骨开始生长，而且组织得到足够的养分，神经就可以从器官器官再生的部位移除，力量，是细胞在早期形成的时间得到的Singer，则证明了：任何细胞组织，对再生来说，是不相关的，不管是运动、感觉、自动的，都在胚芽中呈现。

Objective To investigate the clinical features, causes of blindness and diagnosis of Vogt Koyanagi Harada syndrome Methods The data of 157 patients with VKH syndrome were reviewed and analyzed Patients were carefully examined with slit lamp, ophthalmoscope, three mirror lens, fundus fluorescein angiography, indocyanine green angiography and HLA typing Results Headache was noted in 73 5% of these patients Simultaneous involvement of both eyes occurred in 80 8% of these patients Chroiditis,papilledema and edema of the retina adjacent to the optic nerve were noted in 100% of these patients in the posterior uveitis stage, whereas recurrent granulomatous anterior uveitis (98 4%),"sunset glow" fundus (95 8%) and Dalen Fuchs nodules (71 2%) were the common ocular findings in the recurrent anterior uveitis stage The common causes of blindness were papillitis, exudative retinal detachment and complicated cataract in the posterior uveitis stage, anterior uveal involvement stage and its recurrent stage Poliosis (36 3%) and alopecia (35 0%) were the most common extraocular findings Early irregular patches of fluorescence, followed by localized hyperfluorescent spots were the typical findings of FFA Dilation of choroidal vessels and leakage of ICG from the choroidal vessels were the common ICGA findings The prevalence of HLA DR4 and HLA DRw53 in patients (54 9% and 71 8% respectively) was significantly higher than that in controls (14 7% and 38 2% respectively) Conclusions VKH syndrome is characterized by chroiditis, papillitis or neuroretinitis in the posterior uveitis stage, followed by a generalized uveitis with a typical recurrent granulomatous anterior uveitis Extraocular findings and relevant examinations including FFA, ICGA and HLA typing are helpful to the diagnosis of VKH syndrome

目的探讨Vogt-Koyanagi-Harada综合征患者的临床特征、盲目原因及诊断等有关问题。方法对在1996年1月至2000年12月间就诊资料完整的157例VKH综合征患者进行回顾性分析，并对裂隙灯、眼底镜、三面镜、荧光素眼底血管造影(fundus fluorescein angiography，FFA)、吲哚青绿血管造影(indocyanine green angiography，ICGA)及人类白细胞抗原分型等检查结果进行分析。结果 VKH综合征最常见的前驱症状为头痛(102例，73.5%)，双眼同时患病118例(80.8%)；后葡萄膜炎期眼部主要表现为脉络膜炎、视乳头及附近视网膜水肿(100.0%)；前葡萄膜炎反复发作期眼部表现为复发性肉芽肿性前葡萄膜炎(128例，98.4%)、晚霞状眼底改变(95.8%)及Dalen-Fuchs结节(71.2%)；后葡萄膜炎期、前葡萄膜受累期及前葡萄膜炎反复发作期导致盲目的主要原因分别为视乳头炎、视网膜脱离及并发性白内障；毛发变白(36.3%)及脱发(35.0%)是最常见的眼外表现；炎症活动期FFA典型表现为斑驳状高荧光，ICGA发现脉络膜血管扩张、通透性增高等改变；VKH综合征患者HLA-DR4及HLA-DRw53的阳性率(54.9%及71.8%)显著高于正常对照组(14.7%及38.2%)。结论 VKH综合征患者在后葡萄膜炎期眼部典型表现为双侧脉络膜炎、视乳头炎或神经视网膜炎，随后出现以反复发作的肉芽肿性前葡萄膜炎为特征的全葡萄膜炎。眼外症状及相关的辅助检查包括FFA、ICGA 及HLA分型等有助于VKH综合征的诊断。

RESULTS: Totally 57 rats enrolled in this study, all animals completed Hot pain allergic symptom could not be observed on rats in experimental group during the whole experimental process, but continuously appeared in discharge percentage of nerve fibers at the central end of experimental rat sciatic nerve was remarkably lower than that of the control group 6.79％Sympathetic postganglion nerve fiber budding was not obvious in the slices of entire L4-5 dorsal root neuroganglion of injury side in 6 experimental rats,and basket-shaped cell could not be observed, but sympathetic postganglion nerve fiber budding was obvious in 2 rats in control groups with altogether 41 basket-shaped cells observed.

电生理实验：实验组大鼠坐骨神经中枢端的神经纤维自发放电百分数显著低于对照组(6.79％，46 7％)。③背根神经节切片荧光染色结果：实验组6只大鼠损伤侧L4-5的全部背根神经节切片中看不到明显的交感节后神经纤维芽生，没找到篮状细胞，而在对照组2只大鼠损伤侧L4-5的全部背根神经节切片中可看到明显的交感节后神经纤维芽生，共找到篮状细胞41只。

In order to further investigate the relationship of SP and ESCs, we design two level experiments —in vitro and in vivo. In vivo, firstly, We establish the nomal rat full-thickness wounds model, and employ integrin β1 keratin 19(K19)、 keratin 15(K15)、 Brdu as ESCs markers to conform the existence of ESCs in the granulation tissue of Group Capsaicin (rats were subcutaneously injected capsaicin pre-injury to damage sensory neuron and block the secretion of neuropeptides), Group Control, and Group SP (rats were injected SP in the wound postinjury). Secondly, as diabetic skin lacking of SP due to extensive pathological changes of sensory ending, we make a hypothesis:one of the main reason of unhealing wounds on diabetic patients could be insufficient SP which lead to fewer ESCs recruitment around wounds.

在此基础上，为进一步验证P物质促进表皮干细胞向肉芽组织中募集这一重要发现，本研究首先利用β1整合素、K19、K15等干细胞标记物以及干细胞慢周期性的特点，分别在体观察了正常皮肤伤口愈合过程中SP组、辣椒素组采用特异性感觉神经毒性药物辣椒素(capsaicin皮下预注射化学性除去感觉神经从而阻止神经肽分泌、对照组肉芽组织中表皮干细胞分布特点；其次，糖尿病患者皮肤存在周围末梢神经的损伤和神经肽含量的下降，这是否会导致糖尿病皮肤伤口创缘表皮干细胞募集不足，继发伤口难愈？

In order to confirm this suspect, we choosed a cultured rat granulation tissue fibroblasts model in vitro and applied RT-PCR and cell-ELISA technology to detect the changes of firbroblasts intrinsic EGF, bFGF, TGFβ-1 with their receptors gene expressions and protein synthesises after stimulated by SP. Our purpose was to explore the possible effects and patterns imposed by SP on fibroblasts intrinsic growth factors and their receptors expressions, which maybe offer theoretical basis for promoting wound healing via improving nervous functions and regulating neuropeptides secretions.

为进一步验证这一推测，同时排除在体多因素干扰，我们采用了一种大鼠肉芽组织成纤维细胞体外培养模型，采用RT-PCR与细胞ELISA技术，检测SP刺激成纤维细胞后，成纤维细胞内源性EGF、bFGF、TGFβ-1及其受体基因表达和蛋白合成的改变情况，探讨SP对成纤维细胞内源性生长因子及其受体表达的影响以及方式，以期为经由改善神经功能、调节神经肽分泌途径促进伤口愈合提供理论依据。
