目的：探讨经阴道超声（TVS）诊断子宫肌瘤的准确性及监床应用价值。方法：回顾分析2007年1月～2007年8月143例子宫肌瘤的经腹壁及经阴道超声检查的图像表现和诊断。结果：经腹壁超声诊断子宫肌瘤125例发现146个肌瘤；经阴道超声诊断140例发现166个肌瘤。与经腹壁相比，经阴道超声敏感性提高了12．05％，准确性提高了10．49％。经阴道超声诊断子宫肌瘤的准确率为97．82％，经腹壁超声诊断子宫肌瘤的准确率为87．41％。结论：经阴道超声诊断子宫肌瘤准确率更高，对诊断小肌瘤更有价值。     

经腹—会阴部途径联合超声扫查法诊断盆腔静脉曲张症

本文报道了经腹－会阴部途径联合超声扫查法对３６例经造影证实的盆腔静脉曲张症患者进行观察、分析，结果诊断符合率为１００％，较单独经腹部途径的７８％或经会阴途径的８３％为高。提出两种方法的联合应用互补了方法学上的不足，具有肯定的临床应用价值。     

谈引经药

引经药，始见于张洁古《珍珠囊》，其意系为随经选取能引导其他药物的药力，直达某一病变的经络脏腑部位之药，如：手足太阳经，羌活、藁本；手足少阳经；柴胡，足阳明经，升麻、葛根等。这些药物主要作为各经用药的向导，所以叫做引经药，属于方剂君臣佐使组成中的使药的一类药物。为了正确了解和使用这类药，更好地发挥其在整个处方中的作用，特谈如下：     

股动脉介入治疗致脊髓损伤二例

经股动脉插管介入治疗实体肿瘤为有创治疗，偶有并发症发生，但严重并发症罕见，引起脊髓损伤导致截瘫极少报道。我院开展经股动脉插管介入治疗近２万人次，发生脊髓损伤２例。现报告如下。例１男，５３岁。原发性肝癌，外院经股动脉插管化疗１次，２个月后经我院手术切除...     

肝脏局灶性结节性增生的临床病理特征与处理

作者回顾性分析了15例肝脏局灶性结节性增生（FNH）的临床特点、综合影像表现及病理特征，发现患者以中青年为主，男女比为3：1；经B超、CT、MRI综合影像学诊断，订前5例明确为FNH；11例经手术切除，4例经穿刺活检病理诊断为FNH。该结果提示，FNH经多种影像学检查及综合分析虽可获得初步诊断，但仍有误诊，应首选手术治疗，对于穿刺活检确诊者可以随诊观察。     

胰岛素经眼给药的药物代谢动力学

用国产胰岛素在54只新西兰大耳白家兔体内观察其经眼给药后药物代谢动力学特征。结果表明：分子量约为6000的胰岛素滴眼后能有效地进入血液循环，体内药物动力学为开放性一级动力学一房室模型。消除半衰期为40-60min，与静脉注射相比，消除半衰期明显延长，达峰时间为20-50min。金属络合剂EDTA对胰岛素的经眼吸收有促进作用，经眼给药后体内药物的浓度呈现出剂量依赖性。     

子宫平滑肌瘤病经静脉延伸至右侧心腔的影像学诊断

目的 探讨子宫平滑肌瘤病经静脉延伸至右侧心腔的影像学特点及诊断。方法 对5例子宫平滑肌瘤病经静脉延伸至右侧心腔的病例进行回顾分析，5例均行胸部X线平片、超声心动图，3例行电子束CT(EBCT)检查，2例行MRI和DSA检查。结果 3例行EBCT检查者中2例诊断为子宫平滑肌瘤(肉瘤可能)，肿瘤经静脉延伸至右侧心腔并侵及肺动脉(1例病理诊断为子宫平滑肌瘤病，1例未手术)，另1例诊断为子宫平滑肌瘤经静脉延伸至右侧心腔(未手术)；2例行MR和DSA检查诊断为子宫平滑肌瘤经静脉延伸至右侧心腔。5例患者中3例病理诊断为平滑肌瘤病。结论 子宫平滑肌肿瘤可以经静脉延伸至右侧心腔，罕见，称为子宫平滑肌瘤病，临床有一定特点。CT、MRI、DSA有相应的征象，影像学表现常呈生物学恶性征象，但积极手术治疗仍可得到良好临床效果。

胃嗜酸性肉芽肿的X线诊断

胃嗜酸性肉芽肿是一种罕见疾病，病因不明。临床上缺乏特异性表现，X线表现具有一定的特征性。我们搜集了近20年来我院收治的17例。17例均经钡餐及胃镜取活检检查．钡餐检查均诊断为本病，而胃镜取活检，病理证实为9例，其中4例经手术后病理证实，8例经激素诊断性治疗而证实。     

肾盂移行细胞癌的影像诊断

目的比较静脉尿路造影（IVU）、逆行尿路造影（RU）、B超、CT检查对肾盂移行细胞癌的诊断敏感性。方法回顾性分析28例经手术病理证实的肾盂移行细胞癌的影像学资料，18例经IVU检查；14例经逆行。肾盂造影；28例均经CT检查，其中11例为平扫，17例为平扫加增强；20例经超声检查。结果对照手术病理结果，IVU的敏感性为55，6％（10／18）；逆行肾盂造影的敏感性为92．9％（13／14）；CT检查的敏感性为89．3％（25／28）；B超的敏感性为60％（12／20）。结论RU准确率最高，CT和B超其次，IVU最低，但因IVU是无创性检查，临床依然将其作为肾盂移行细胞癌常规的首选检查方法，RU，CT和B超作为IVU重要的补充。     

Echography of the oral phase of deglutition

Neither cineradiography nor videorecording are satisfactory techniques for the dynamic study of the oral phase of deglutition. Therefore, oral swallowing was studied by means of real-time sonography (US) in 20 asymptomatic patients. Both anatomy and motility of the muscles of the mouth and tongue were clearly demonstrated. Real-time US proved thus to allow an accurate and dynamic visualization of the oral phase of deglutition.

Thermal versus suture treatment of symptomatic capsular laxity

This article reviews the clinical results of unipolar thermal capsular shrinkage in 30 patients and compares that group to similar groups previously managed by laser-assisted capsulorrhaphy or by an arthroscopic capsular shift procedure. Patients were evaluated with respect to incidence of recurrent instability, the need for reoperation, and the ability to return to previous levels of activity or sports participation. Patients were rated as satisfactory or unsatisfactory based on criteria established by Neer. The results of this study suggest that thermal capsulorrhaphy with rotator interval plication is an effective treatment alternative for multidirectional instability, with results comparable to those previously reported with open and arthroscopic procedures.     

Intraarterial digital subtraction arteriography in the diagnosis and treatment of hepatic tumors

Intraarterial digital subtraction arteriography (IADSA) was performed in 94 patients with hepatic tumors and evaluated on the following subjects: 1) visualization of small arteries in arterial phase, compared with film study, 2) visualization of faint tumor stains in hepatogram phase, compared with film study, 3) visualization of portal venous branches by intraarterial digital subtraction portography (IADSP). Interventional angiography was performed in 76 patients. Contrast dose and injection rate of IADSA was approximately a third of film study without dilution. The position of the catheter was identical in IADSA and film study. IADSPs were performed with 15-20 ml of 76% Urografin, which was injected into the superior mesenteric artery at the rate of 5 ml/sec after infusion of prostaglandin E1. Comparison in arterial phase of 67 patients showed 24 (36%) IADSAs were equal to film study. Thirty-nine (58%) were inferior but adequate for the diagnosis of hepatic tumors. Comparison in hepatogram phase showed 24 (38%) IADSAs were superior to film study and all were satisfactory for the diagnostic purposes. Ninety-eight percent of 86 IADSPs gave information about the patency of the main portal vein. Fifty-five percent of IADSPs opacified third-order portal vein branches or further. IADSA of hepatic tumors not only save time and contrast dose but was also satisfactory in image quality for interventional angiography.     

Diagnostic accuracy of sequential angio-urography with the spot-camera in clinical practice

In this perspective study the authors examined 57 patients to evaluate diagnostic accuracy of sequential angiourography (AUS) using spot-camera and image subtraction for the visualization of the vascular phase of the renal arteries. All the subjects underwent surgery or follow-up with other clinical and radiological methods. The results obtained with this technique, of low cost and simple execution, were satisfactory: accuracy 98%, sensitivity 100%, specificity 98%.
