目的：探讨无肌病性皮肌炎的临床特点。方法：回顾性分析符合Euwer提出的ADM诊断标准的5例患者的临床资料，包括临床症状体征、肌酶谱、肌电图、肌肉病理检查、胸部影像学检查、治疗方案。结果：所有患者均先后出现皮肌炎典型皮损，无肌痛或肌无力等主诉，肌酶谱、肌电图均正常。2例抗核抗体阳性，3例有肌活检非特异性改变，1例合并间质性肺炎，无患者合并恶性肿瘤。结论：皮肌炎是一种复杂的综合征，需要行全身系统检查，结合肌电图和肌肉病理检查进行综合诊断。
目的 探讨不同诊断或分类标准在脊柱关节病患者之间诊断效能、临床特点。 方法 收集2000年2月－2012年8月141例脊柱关节病患者及197例类风湿关节炎、未分化关节炎患者资料。采用3种诊断标准下对141例患者分为纽约标准（NY）组、欧洲脊柱关节病研究（ESSG）组及脊柱关节病国际评估（ASAS）组，统计患者的临床表现、骶髂关节CT、MRI、实验室指标，并加入197例类风湿关节炎未分化关节炎患者，计算和比较3种诊断的敏感性、特异性。 结果 在141例脊柱关节病中，62例符合NY标准，34例符合ESSG标准，45例只符合ASAS标准。3组患者在性别、胸廓受限、附着点炎及跖（指）炎、非甾体抗炎药及慢作用药使用、炎症因子水平方面差异无统计学意义（P＞0.05）；ASAS组则较19 NY组及ESSG组患者更年轻、病程较短，且表现有外周关节炎明显高于其余两组（P＜0.05）；NY组炎性腰背痛、脊柱活动受限、HLA-B27阳性率明显高于其余两组，且使用生物制剂比例最高，达48.38；在骨盆X线、骶髂关节CT表现关节侵蚀上，NY组较其他两组更严重。NY、ESSG、ASAS分类标准敏感性依次为43.97%、47.51%、73.76%，特异性依次为100.00%、90.86%、84.26%。 结论 ASAS分类标准敏感性高，患者更年轻、病程更短，炎性腰背痛、外周关节炎是ASAS诊断中非常重要的指标；NY组脊柱活动受限及关节侵蚀最显著，HLA-B27阳性可能是预测AS很好的指标。NY标准特异性最高，敏感性最低，而ASAS标准敏感性最高，特异性最低。
Objective To verify the predictive value of Sino System for Coronary Operative Risk Evaluation（SinoSCORE） on quality of life in patients undergoing coronary artery bypass graft （CABG） surgery. Method A total of 234 patients in Peking University People’s Hospital undergoing CABG between November 2008 and September 2010 hadcompleted the preoperative and 6-month postoperative Short Form-36 （SF-36）. There were 172 （73.5%） male patients and63 （26.5%） female patients. The average age was 63.0±10.1 years. According to the SinoSCORE， 234 patients were dividedinto three groups：low risk （SinoSCORE score less than 1 point，n=67）， medium risk （SinoSCORE score 2-5 points，n=77） and high risk （SinoSCORE score more than 6 points，n=90） group. Clinical information of the 234 patients was collected， andthe score values of all patients were calculated according to the SinoSCORE model. Statistic methods were performed toevaluate the relationship between quality of life and SinoSCORE. Results The postoperative quality of life have improvedsignificantly， but the improvement of quality of life have no significantly different between groups. There was statisticallysignificant correlation between quality of life and SinoSCORE （P＜0.05， r value at-0.150 to 0.255）.Linear regression analysis showed that SinoSCORE was significantly collected with quality of life in multiple subgroups （P＜0.05， r 2＜0.1） .Conclusion SinoSCORE have statistically correlated with quality of life， and have certain but limited predictive value on quality of life in CABG patients.
【摘要】 目的 提高对系统性红斑狼疮(SLE)并发急腹症(AA)临床复杂性的认识,总结诊治经验。方法 对2008年以来收治20例系统性红斑狼疮并发急腹症的患者进行回顾性分析,并复习近9年相关文献。结果 系统性红斑狼疮住院患者中并发急腹症发生率2.56％；急腹症多数(80%)与系统性红斑狼疮病情活动相关,也可能由独立于系统性红斑狼疮的其他疾病引起(20%),病情复杂,容易误诊。腹部CT尤其是增强CT检查对确定系统性红斑狼疮相关急腹症病因有重要作用。结论 系统性红斑狼疮活动是系统性红斑狼疮并发急腹症最主要的原因,SLEDAI评分在系统性红斑狼疮并发急腹症鉴别诊断中有一定作用。及时诊断、正确治疗后,系统性红斑狼疮活动相关急腹症患者的预后较好。
Objective To research the transfer of adenovirus human bone morphogenetic protein 4 (Ad-hBMP-4) to human degenerative lumbar intervertebral disc cells in vitro and analyze its effect on the proteoglycan, collagen type II, and Sox9 of intervertebral disc cells. Methods Identified Ad-hBMP-4 was amplified and detected. Degenerative lumbar intervertebral disc cells were aspirated from the degenerative lumbar intervertebral disc of patients with Modic III level disc protrusion (aged, 27-50 years). The expressing position of collagen type II was identified in the intervertebral disc cells through the laser confocal microscope. The intervertebral disc cells at passage 1 were transfected with Ad-hBMP-4 as experimental group. After 3 and 6 days of transfection, RT-PCR was used to detect the mRNA expressions of proteoglycan, collagen type II, and Sox9, and Western blot to detect the expressions of proteoglycan and collagen type II proteins. Non-transfected cells at passage 1 served as control group. Results The virus titer of Ad-hBMP-4 was 5 × 106 PFU/mL. No morphological changes in the cells after transfection by Ad-hBMP-4. Collagen type II mainly expressed in the cell cytoplasm. The mRNA expressions of the proteoglycan, collagen type II, and Sox9 in experimental group at 3 and 6 days after transfection were significantly higher than those in control group by RT-PCR (P lt; 0.05), and the expressions of proteoglycan and collagen type II proteins were significantly higher than those in contorl group by Western blot (P lt; 0.05). There were significant differences between 3 days and 6 days in experimental group (P lt; 0.05). Conclusion Ad-hBMP-4 could transfect human degenerative lumbar intervertebral cells with high efficiency and promote collagen type II, proteoglycan, and Sox9 expressions. hBMP-4 may play an important role in the repair process during early disc degeneration.
Objective To evaluate the results of open arthrolysis by elevated the lateral and medial collateral l igament-musculature complex from the supracondylar ridge of the humerus in treatment of post-traumatic elbow stiffness. Methods From March 2003 to December 2007, 33 patients with post-traumatic elbow stiffness were treated with open arthrolysis by elevated the lateral and medial collateral l igament-musculature complex from the supracondylar ridge of the humerus. There were 23 males and 10 females, aged 17-70 years old (mean 41.8 years old). According to Morrey, 15 caseswere extremely serious (less than 30° extension-flexion arc) and 18 cases were serious (30-60° extension-flexion arc). The range of motion of the elbow stiffness was (32.5 ± 28.9)° and the Mayo score was 51.9±13.1 before operation. All initial fractures were healed according to cl inical examination and X-rays films. All patients present with a post-traumatic elbow stiffness and the average period from initial trauma to elbow arthrolysis was 16.9 months (2-72 months). Results Wound infection occurred in 1 patient and cured after dressing change and anti-infectious treatment. The wounds healed by first intension in 32 cases. No patient showed sign of elbow instabil ity and debil itating pain. All patients were followed up 6 months to 5 years (mean 3.3 years). At last follow up, the Mayo score was 82.3 ± 14.4 and the range of motion of elbow stiffness was (108.8 ± 36.0)°; showing significant differences when compared with preoperation (P lt; 0.05). According to Mayo evaluation, the results were excellent in 11 cases, good in 18 cases, fair in 2 cases, and poor in 2 cases, the excellent and good rate was 87.88%. Thirty-one patients achieve satisfactory results. Two patients were not satisfied with the result, but the satisfactory results were achieved by a second arthrol ysis. Conclusion Open elbow arthrolysis and postoperative rehabil itation for patients with elbow stiffness can improve joint function and ensure the stabil ity of elbows.
