无关节的

Superior border in all 13 subjects treated with fixed inclined bite??plate. MRI??signs of glenoid fossa remodeling at anterior??inferior border of post??glenoid spine were noted in 2 of 13 subjects. Condylar??fossa relationship changes were unconspicuous before and after treatment.

结果： 13例患者MRI结果均可见到髁突后上部发生改建，有新骨形成的表现；2例可见到关节窝改建，位于关节后结节的前缘下方，治疗前后髁突在关节窝中位置无明显变化。

Results There was no significant difference in complication rate in three groups.The time when shoulder joint circumduction and ear touching recover completely both has a positive correlation with the time when shoulder joint motion starts.

结果 术后7天、14天患肢并发症的发生率前两组高于第3组，但差异无统计学意义；术后1个月、2个月、3个月及6个月患肢并发症的发生率三组差异无统计学意义；患肢肩关节环转运动、摸耳运动恢复时间分别与患者术后肩关节活动时间呈正相关。

MRI can display not only in hyperosteogeny,but changing in articular meniscus,anticular cartilage,ligament and hydrarthrosis as well.MRI also shows instructive bearings in individualizing treatment and increases early diagnosis rate.

它是一种无创伤、无辐射、信息多的新方法，不仅能显示骨质病变，尤其能显示半月板、关节软骨、韧带及关节腔积液等病变情况，能提高早期诊断率，对治疗个体化有指导意义。

The results were expressed in mean±1SD. Pearson X~2 test and One-way ANOVA test were used. The data analyzed using the SPSS (version 11.5). Results: The sensitivity, specificity, positive and negative value of US for the LPEH model on the children cadaver were 88%, 84%, 79%, 91%, respectively. With regard to the thickness of femora head cartilage, the thickness of the anterior layer or posterior layer, there were no significant differences among three groups. However, the anterior layer was thicker than the posterior layer in three groups. The fluid in hip joint was detected in all of 21 symptomatic hips, which was clear commonly (90%) in early procedure. The amount of fluid in anterior recess showed a positive correlation with age (p .05). No fluid was detected in the asymptomatic and normal hips (2mm). The mean maximum width of inferomedial recess was significantly larger than that of anterior recess (12.50±4.04mm vs.4.35±0.8mm, p 0.05) in the symptomatic hip joints. The echogenic entrapped labral plicaes were demonstrated in the inferomedial recess in all of 21 children with LPEH, whose length and width ranged from 5.3mm-25.0mm (mean,15.6±5.6mm) and from 4.0mm-17.0mm (mean,8.9±7.8mm).

结果1，尸体LPEH髋关节模型的超声诊断敏感性、特异性分别为88％、84％，阳性预测值、阴性预测值分别为79％、91％。2，21例患儿的LPEH患髋(21侧)、健髋(21侧)，以及21例正常儿童健髋(42侧)的超声检查显示：髋关节周围软组织及股骨头无形态结构差别；股骨头软骨厚度无统计学差异(3.5±0.5mm vs.3.6±0.4mm vs.3.6±0.5mm，p＞0.05)；关节囊前层及后层厚度无统计学差异(前层厚度2.79±0.74 mm vs.2.56±0.40mm vs.2.56±0.72mm；后层厚度2.70±0.82mm vs.2.48±0.54mm vs.2.44±0.58mm，p＞0.05)，但LPEH患髋关节囊前、后层均较后二组有增厚趋势。3，LPEH患髋均存在关节腔内积液，且早期较为清晰；积液以髋关节内下间隙明显，内下间隙较前间隙明显增宽(12.50±4.04mm vs.4.35±0.8mm，p＜0.05)，其内见嵌顿滑膜唇皱襞呈稍强回声的占位性团块，长约15.6±5.6mm，宽约8.9±7.8mm，90.5％(19／21)嵌顿皱襞内未见血流信号。4，所有LPEH患髋治疗后超声复诊均显示正常。

Results High purine diet is the main diet habit of the gout people, young and middle aged male prefer to alcohol. The cause of gout in young and middle aged male is drinking mass of alcohol and strenuous exercise,while old aged male is catching cold,changing weather and the use of diuretic. Young and middle aged male will first outbreak at the first metatarsophalangeal joint,involve in single joint,while old aged male at the knee and ankle,involve in two to three joints. Old aged male always go with hypertension, coronary heart disease and diabetes,the rate is significantly higher than that in young and middle aged male(P＜0.05), while the rale of hyperlipemia is similar in two groups.

结果 两组患者均嗜好高嘌呤饮食，中青年男性饮酒明显多于老年男性患者；发病诱因方面中青年男性主要有剧烈运动、大量饮酒，而老年男性主要是感冒、天气变化及使用利尿剂；中青年男性痛风首发第一跖趾关节为多，多数累及单关节，而老年男性则以膝、踝等大关节为多，累及2～3个关节；老年男性合并高血压、冠心病、糖尿病的概率比中青年男性多，两者差异有统计学意义(P＜0.05)，但两者合并高脂血症的概率则无明显差异。

Results Extensive and diffuse synovial hyperplasia can be seen in patients with RA;synovial pannus formation can be seen in 25 cases.

结果RA组病人均可见广泛、弥漫的滑膜增生，其中25例病人可见滑膜血管翳形成，而OA组仅7例病人可见轻度滑膜增厚，未见滑膜血管翳形成者(X2=55.78P.005)；RA组关节软骨及软骨下骨改变较严重且弥漫，而OA组软骨退变则较局限，且以关节摩擦大的部位受损为著，其软骨下骨改变较为局限，常常见于IV软骨退变；关节腔积液、半月板及韧带改变，在OA组与RA组之间无差异。

The human cartilages are composed of chondrocyte and extracellular matrix,the form of chondrocytes are hypertrophy and the quantity are less;the ECM of cartilage are compised of type II collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury,the ommilayer injury ofcartilage can be recovered by marrow,but because of without stimulation mechanism,the new tissues are merely fibrocartilages,they can not be coincide with hyaline cartilage in menchanics;the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation,thus,the plerosis of articular catilage can not depend on the proliferation of local chondrocyte.Ever since,people tried their best to find a way to reconstruct articular cartilage.

造成人体关节软骨损伤的原因主要为创伤和关节炎，关节软骨全层损伤可由于骨髓中间充质干细胞的高速增殖修复，但这种修复由于缺乏相应的刺激机制，只能形成纤维软骨，而不能形成符合关节生理、力学要求的透明软骨；单纯软骨部分损伤软骨组织内无血管，软骨细胞迁移迟缓，无法使损伤区域软骨细胞再生，因此，关节炎及关节创伤后的软骨修复不能依赖于软骨细胞的增殖和迁移。

Results T-2 toxin could cause rat articular chondroncytes degeneration, necrosis, and appeared many blank areas free cells. Weigert/Van Gieson staining showed obvious collagen fasciculi emergence could be seen. Scanning electronic microscope showed the surface of articular cartilage was wave and rough. Collagen fasciculi ruptured and stack up, and presented a typical 揳rticular dryness?phenomenon. ELISA results indicated, at the stage of 3 month, the level of rat serum CTX-II in T-2 toxin group was higher than that in control group, and the difference had a markedly significance.
