BACKGROUND:Lateral retinacular release is effective to treat anterior knee pain, but it has not been confirmed through the parameters of the knee joint. OBJECTIVE: To analyze the relevant parameters on the axial X-ray films of the patela before and after lateral retinacular release and then to find out the efficient parameters for patelofemoral joint disorders on the axial X-ray film of the patela, which are of most clinical significance. METHODS: Fifty patients with anterior knee pain were included randomly who admitted at the Department of Joint Surgery, Affiliated Hospital of Jining Medical University from February 2009 to December 2013, including 45 cases of Outerbridge I-III undergoing arthroscopic lateral retinacular release+articular cartilage repair and 5 cases of Outerbridge IV undergoing lateral retinacular release+knee joint surface replacement. RESULTS AND CONCLUSION:After lateral retinacular release, the congruence angle, patelofemoral index and tilt angle were al reduced significantly (P < 0.05 orP < 0.01), but there was no change in the lateral patelofemoral angle (P > 0.05). The patelar trajectory restored to the corresponding central position of the femoral condyle, and meanwhile, no joint hematoma, deep vein thrombosis and patelar subluxation occurred. These findings indicate that the lateral retinacular release is of great significance for treatment of anterior knee pain induced by lateral patelofemoral compression.

目的：探讨视频宣教在老年人肺功能测定中的应用效果。方法：选择年龄﹥70岁的老年患者100例，随机分为观察组和对照组，每组50例。观察组患者实施肺功能测试前观看宣教视频和操作者讲解相结合；对照组患者在肺功能测试前讲解相关知识。比较两组患者肺功能检测成功率，并记录操作检查时间。结果：观察组肺功能检测成功率明显高于对照组，所用时间少于对照组，两组比较差异均有统计学意义（ P ﹤0.05）。结论：视频宣教有利于提高老年患者肺功能检测的成功率及缩短肺功能检测时间。

BACKGROUND: The abnormality of some parameters such as congruence angle has statistical significance on anterior knee pain has been confirmed under CT measurement, but has not been confirmed through clinical operations. OBJECTIVE: To analyzes the relationship between the parameter of knee joint and anterior knee pain through measuring the parameters such as congruence angle, patel ofemoral index, lateral patel ofemoral angle and tilt angle. METHODS: Fifty patients with anterior knee pain caused by varying degrees of atel ofemoral cartilage damage were included, and the parameters such as congruence angle, patel ofemoral index, lateral patel ofemoral angle and tilt angle were measured on the patel ar X-ray axial film. The parameters were compared with those of the other 50 patients without anterior knee pain and only with meniscus injury. RESULTS AND CONCLUSION: There were significant differences in congruence angle, patel ofemoral index and tilt angle on the patel ar X-ray axial film, and there was no significant difference in lateral patel ofemoral angle. The congruence angle and patel ofemoral index have important diagnosis value for the patients with anterior knee pain caused by patel ofemoral joint disorders and are considered as the most effective parameters which has clinical efficacy for the patients with patel ofemoral joint disorders.

Objective:To compare the effect of invenous infusion of two type vein detained needles:the safe type vein detained needle and average type vein detained needle.Methods:Two thousands cases with acute coronary syndrome were randomly divided into two groups:the safe type vein detained needle(1 000 examples),the average type vein detained needle(1 000 examples),comparising the sussess rate of one puncture,the failed extracting the intertnal noodle,and the needle injuries and acceptance of price.Results:We find that the sussess rate of one puncture and the failed extracting the intertnal noodle of the safe type vein detained needle are higher than the average groups(P0.05),the injury rate and acceptance of price are lower(P0.05).Conclusion:The safe type vein detained needle is better than the average type vein detained needle in acute coronary syndrome.

<正>血管迷走反射是冠状动脉介入术后的常见并发症,可发生在术中、术后,如不能及早发现而延误治疗可导致不可挽回的后果,术前给予患者护理干预,术中、术后细心观察,及早发现迷走神经反射患者并精心护理是保证患者尽早脱离危险的关键。

目的 探讨自体骨植骨应用于全髋关节置换术(THR)中髋臼缺损的临床疗效.方法 对50例(50髋)髋臼缺损的全髋关节置换术进行分析,根据骨缺损情况进行髋臼自体骨植骨(结构性植骨、颗粒植骨).结果 50例获平均随访24.2个月,49例髋臼植骨处愈合.术后2周Harris评分67～82分,平均79.5分;术后1年86.5～94.6分,平均91.3分.结论 髋臼自体骨植于髋臼骨缺损处,可以恢复髋臼的完整性,增加髋臼的骨覆盖,提高THR术后髋臼假体的稳定性.

目的 探讨人工髋关节翻修重建术的翻修原因和临床疗效.方法 对2005年6月至2009年6月行人工髋关节翻修重建术28例患者进行随访,用Harris评分法,对人工髋关节翻修重建术的临床疗效进行评估.结果 28例患者术后随访6～48(34.0±8.6)个月.27例患者疼痛消失,关节功能恢复良好,1例患者因翻修术后发生感染,给予清创灌洗及抗生素抗感染治疗后得到控制.术前Harris评分(45.0±14.9)分,术后(89.0±10.2)分,术前与术后Harris评分比较差异有统计学意义(t=4.58,P=0.0042).结论 疼痛性无菌性假体松动是人工髋关节置换术主要的翻修原因,术中应根据患者年龄、骨缺损的类型等选择不同的假体类型,规范手术操作,加强功能锻炼,提高临床疗效.
