16层螺旋CT对肋骨骨折的诊断价值

随着工业化进程的加速及交通事故的增加,胸部创伤日渐增多。国内报道在45 569例创伤中,胸部创伤占1·47%[1],其中肋骨骨折非常常见。随着螺旋CT检查临床应用日趋广泛,其高敏性、快速成像的特性及强大的后处理功能越来越在肋骨骨折中显现重要作用。本文对53例肋骨骨折患者的16层     

Warfarin or Low-Molecular-Weight Heparin Therapy does not Prolong Pig-To-Primate Cardiac Xenograft Function

Microvascular thrombosis is a prominent feature in cardiac delayed xenograft rejection (DXR). We investigated the impact of warfarin or low-molecular-weight heparin (LMWH) anti-coagulation on xenograft function using a heterotopic pig-to-primate model. Donor hearts were from CD46 transgenic pigs and baboon immunosuppression included tacrolimus, sirolimus, anti-CD20 and TPC, an alpha-galactosyl-polyethylene glycol conjugate. Three groups of animals were studied. Group 1 (n = 9) was treated with warfarin, Group 2 (n = 13) with LMWH and Group 3, received no anti-coagulant drugs. The median duration of xenograft function was 20 days (range 3-62 days), 18 days (range 5-109 days) and 15 days (range 4-53 days) in Groups 1 to 3 respectively. Anti-coagulation achieved the targeted international normalized prothrombin ratio (INR) and anti-factor Xa levels consistent with effective in vivo therapy yet, no significant impact on median xenograft function was observed. At rejection, a similar histology of thrombosis and ischemia was apparent in each group and the levels of fibrin deposition and platelet thrombi in rejected tissue was the same. Anti-coagulation with warfarin or LMWH did not have a significant impact on the onset of DXR and microvascular thrombosis. However, a role for specific anti-coagulant strategies to achieve long-term xenograft function cannot be excluded.     

乳腺影像学报告及数据系统:超声良恶性病变鉴别诊断初探

1992年美国放射学会制定了乳腺影像学报告及数据系统(breast imaging reporting and data system,BI-RADS),2003年第四版修订时包括了超声诊断(BI-RADS-US)。本文旨在初步探讨BI-RADS-US对于乳腺良恶性病变鉴别诊断的能力。我们收集了2006年1月至2007年3月期间、获得病理诊断的乳腺占位性病变共69例72灶。均为女性,年龄14-83岁,平均41.6岁。首先根据一般的非BI-RADS标准,做出良恶性鉴别。然后用BI-RADS-US标准进行鉴别和分级(0-6级),其中2级和3级为良性和良性可能性大,4级为性质待定,5级为恶性可能性大。计算并比较上述两种方法的准确性、敏感性、特异性。结果在72病灶中,根据非BI-RADS标准,诊断为良性者40灶,符合病理诊断者38灶(95.0%),诊断为恶性者23灶,符合病理者18灶(78.3%);诊断为性质待定者9灶。根据BI-RADS-US标准和分级,2级和3级共有37灶,与病理结果符合者为36灶(97.2%);5级有31灶,与病理符合者为22灶(71.0%);4级有4灶。非BI-RADS和BI-RADS-US的准确性各为83.3%和81.9%(P=1.000),敏感性各为91.7%和95.8%(P=1.000),特异性各为79.2%和75.0%(P=0.754)。总之,第一版BI-RADS-US在乳腺良恶性病变鉴别诊断方面的初步应用表现出较高的敏感性,而与非BI-RADS方法比较则尚无明显差别。     

手术治疗125例分化性甲状腺癌的5年随访结果分析

目的：探讨甲状腺全切除术在治疗分化性甲状腺癌中的临床应用价值。方法：采用我院1988年1月～2001年5月甲状腺全切除术或甲状腺侧叶切除加峡部切除术治疗分化性甲状腺癌125例,对其手术并发症发生、局部复发、转移情况及术后5年生存率进行回顾性对比分析。结果：甲状腺全切除术术后并发症发生率高于甲状腺侧叶切除加峡部切除术组;局部复发、转移率低于侧叶切除加峡部切除术组;5年生存率两组无显著性差异。结论：甲状腺全切除术是治疗甲状腺癌有效的手术方式,但应掌握手术指征,改进、提高手术技术,减少并发症。     

手术室护理人力资源的合理开发和利用

随着医院逐渐向企业化管理模式的迈进，人员队伍优化组合、减员增效、定编定岗等方面的问题日益突出，如何解决这个问题，是摆在基层管理者面前的一个必须思考的问题。近年来，我们在手术室人力资源管理上进行了一些探索，通过实践摸索出了一套人力资源开发和利用的方法，取得了一定成效，现将具体做法介绍如下：

浅谈乳腺叶状囊肉瘤与乳腺纤维腺瘤超声影像的相关性及临床意义

乳腺纤维腺瘤发病率在乳腺良性肿瘤中居首位,而乳腺叶状囊肉瘤在临床恶性病变中也并不罕见,有的学者报道与乳腺癌之比可达1∶20.国内有些学者认为,叶状囊肉瘤虽然可以由纤维腺瘤经肉瘤变而成,但是也可能开始时就是肉瘤.本文通过对32例经手术病理证实的病例进行回顾分析,以探讨二者超声影像的相关性及临床意义.

Differences in SLE disease activity between patients of Caucasian and South‐East Asian/Chinese background in an Australian hospital

Aim: We performed a semiprospective and retrospective review of all admissions to a single institution of systemic lupus erythematosus (SLE) patients, admitted due to active disease. The aim was to describe differences in disease activity as a cause of hospital admissions between patients originating from South‐East Asia/China (SAC) and Caucasians. Method: There were 210 patients admitted for active disease, with a total of 567 admissions for active SLE over a 16‐year period. Allowing for patients who had left our database, there was a total of 3415 patient years of observation. Results: Patients from SAC with a flare requiring admission presented earlier in their disease course and with more active disease than did Caucasians (median SLE Disease Activity Index 13 vs. 8, P= 0.002). They had longer inpatient stays (7 vs. 5 days P = 0.03). There was a trend to higher rates of re‐presentation to hospital for flare (59% in SAC patients vs. 41% in Caucasians, P = 0.09) with more subsequent admissions (3 vs. 2 P = 0.06) despite a shorter period of observation. Conclusions: South‐East Asian/Chinese were more likely to be diagnosed with class III/IV glomerulonephritis and require cyclophosphamide both at presentation and subsequent admissions. More patients from SAC were readmitted to hospital for severe central nervous system disease after their first hospital admission. In this population, lupus patients had more severe flares and more frequently required admission for these than Caucasians.     

两种比色板在前牙修复中效果分析

目的旨在探讨Vitapan Classical比色板和Vitapan3D-Master比色板在口腔修复科临床中的比色效果,以指导临床工作。方法采用修复前比色、修复体制作完成后口腔外比色以及口腔内核对颜色的方法,对比两种比色板的比色效果。结果修复体制作完成后,在口腔内、外核对颜色时,使用Vitapan3D-Master比色板的满意度高于Vitapan Classical比色板(P<0.05)。结论Vitapan3D-Master比色板颜色范围较宽,临床比色可以取得较好的效果。
