MRI对先天性心脏位置异常的诊断价值

目的：探讨磁共振成像（MRI）对先天性心脏位置异常的诊断价值,方法：对本组患儿10例,应用超导磁共振仪,选用心电图门控自旋回波技术（SE）,电影磁共振（cine-MRI)及磁共振造影（MRA）进行诊断,所有病例均经X光胸片和二维彩色多普勒超声心动图检查,其中3例同时进行心血管造影（Angio)检查,一例经手术治疗,结果：MRI准确显示本组患者的心脏和／或内脏位置异常,诊断结果包括右旋心4例,镜像右位心3例,中位心2例及孤立性左位心1例。结论：MRI能准确诊断先天性心脏位置异常。     

血清唾液酸含量诊断胃疾病探讨

测定慢性浅表性胃炎１５例,萎缩性胃炎５例,胃溃疡１５例,胃癌９例患者血唾液酸（ＳＡ）的含量。结果表明在４组胃疾病中,胃癌、胃溃疡ＳＡ比慢性浅表性胃炎高。经统计学处理（方差分析）差别有高度显著性（Ｆ＝９１７,Ｐ＜００１）。结论：定期测定ＳＡ含量,对胃部疾患的随访和病情变化有着重要意义。     

Symptomatic Abdominal Aortic Aneurysm with Inferior Vena Cava Malposition

A 66-year old woman was admitted with an acute symptomatic abdominal aortic aneurysm. After preoperative assessment, she was directly operated on via transperitoneal approach.

Intraoperatively, a left-sided inferior vena cava was diagnosed. The preoperative study of the abdominal computed tomography had not revealed this venous malformation.

Retroperitoneal venous anomalies are a major source of unexpected haemorrhage during aortic reconstruction. Thus, for optimal preoperative preparation, a systematic close examination of the preoperative contrast enhanced CT scan of the abdomen is advised.     

Accuracy of patient-specific instrumentation in anatomic and reverse total shoulder arthroplasty

Purpose:Glenoid component malposition is associated with poor function and early failure of both anatomic and reverse total shoulder arthroplasty. Glenoid positioning is challenging particularly in the setting of bone loss or deformity. Recently, the use of computer assistance has been shown to reduce implantation error. The aim of this study is to evaluate the accuracy of patient-specific instrumentation in cases of anatomic and reverse shoulder replacement in vivo.Methods:Twenty patients underwent total shoulder arthroplasty using a computed tomography (CT)-based patient-specific instrumentation (PSI) system, ten anatomic and ten reverse. Preoperative three-dimensional digital templating of glenoid component position was undertaken and surgery then performed using a custom-made guide. Postoperative CT scans were used to compare final implanted component position to the preoperatively planned position in the same patient.Results:Final component position and orientation closely reflected the preoperatively templated position. Mean deviation in the glenoid version from planned was 1.8° ±1.9° (range, 0.1°–7.3°). Mean deviation in inclination was 1.3° ±1.0° (range, 0.2°–4.5°). Mean deviation in position on the glenoid face was 0.5 ± 0.3 mm (range, 0.0–1.3 mm) in the anteroposterior plane and 0.8 ± 0.5 mm (range, 0.0–1.9 mm) in the superoinferior plane. Actual achieved version was within 7° of neutral in all cases except for one where it was deliberately planned to be outside of this range.Conclusion:PSI in both anatomic and reverse shoulder arthroplasty is highly accurate in guiding glenoid component implantation in vivo. The system can reliably correct bony deformity.     

不同术式对腹透导管移位的影响及其透析效果观察

为探讨不同术式对腹透管移位的影响及其使用效果,将患者随机分成两组：①前置组：将腹透管置入陶氏腔;②后置组：将腹透管置入直肠后。结果发现：后置组导管移位的发生率较前置组明显降低,两组出入液时间、超虑量无显著差异。说明后置式置管方式能有效地减少导管移位,同时有较好的使用效果。     

卧位旋牵推拿治疗寰枢关节紊乱综合征

目的：探讨卧位旋牵推拿法治疗寰枢关节紊乱综合征的临床疗效及作用机理。方法将60例寰枢关节紊乱综合征患者随机分为治疗组与对照组,各30例。治疗组采用放松类手法加卧位旋牵法治疗;对照组仅使用放松类手法治疗。2个疗程后观察疗效。结果治疗组总有效率90.00％,明显优于对照组73.33％,差异有统计学意义（P ＜0.05）。结论卧位旋牵法治疗寰枢关节紊乱综合征可解除肌肉紧张,松解黏连,纠正寰枢关节紊乱,恢复患者活动功能。     

悬灸三阴交治疗胎位不正临床观察

目的 探索一种矫正胎位的更简便易行的方法。方法 将120例患者随机分为治疗组和对照组各印例，治疗组悬灸三阴交穴，每日1次，4次为1疗程；对照组悬灸至阴穴，每日1次，4次为1疗程。结果 治疗组痊愈率和有效率分别为90．0％96．7％；对照组分别为86．7％和95．0％。结论 悬灸三阴交矫正胎位疗效确切。
