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.     

Laparoscopic Local Resection Based on Sentinel Node Evaluation for Early Gastric Cancer: A Preliminary Report

We previously reported that lymphatic mapping using isosulfan blue can be used to identify sentinel nodes (SNs). This study was undertaken to evaluate the feasibility of using the SN technique in treating early gastric cancer and to explore its usefulness for minimal invasive surgery. Twenty-three patients with early gastric cancer who underwent SN biopsy were retrospectively evaluated. Based on SN evaluation, individualized surgery was performed in five patients with T1N0M0 gastric cancer. When pathological examination of frozen sections revealed metastasis in SNs, we performed a standard D2 gastrectomy. Laparoscopic local resection was applied when the SN biopsy was negative. Our results showed that the success rate with SN biopsy in early gastric cancer was 100%, as were the accuracy, sensitivity, and specificity. All five patients with early gastric cancer had SNs negative for metastases both by frozen section and by postoperative pathology. Thus, all these patients underwent laparoscopic local resection without extended lymphadenectomy. We conclude that SN biopsy is a useful tool to individualize the operative procedure, and laparoscopic local resection can be safely performed using SN guidance in selected patients with early gastric cancer.     

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。     

输尿管无细胞基质移植物的制备和评价

背景：与小肠黏膜下层等材料相比，脱细胞血管具有天然管状结构，与输尿管形态结构相近，替代输尿管时仅需端端吻合即可，手术操作简单，血管外壁光滑，获取及制备方法简便等优点。 目的：拟应用同种颈动脉血管无细胞基质体外构建输尿管。 设计、时间及地点：观察性实验，于2006-09/2008-06在上海交通大学医学院附属新华医院动物实验中心完成。 材料：长风杂交白猪由上海松联实验动物公司提供。上海交通大学医学院实验动物中心提供的健康成年大鼠8只，用于血管无细胞基质的动物毒性实验。 方法：剥去猪颈动脉血管外膜，PBS冲洗若干遍，然后将血管置于pH 7.1 的PBS中4 ℃下振荡清洗，0.5%十二烷基硫酸钠振荡24 h，后使用双蒸水4 ℃下反复振荡洗涤1周，每日换双蒸水2次。对于解剖过程中肌肉残留相对稍多的血管，在双蒸水洗涤前以混合消化液37 ℃下振荡消化约2 h，再行双蒸水洗涤。制备的无细胞基质置于青、链霉素溶液中，4 ℃保存，完成脱细胞支架制备。 主要观察指标：光镜及电镜观察脱细胞后管壁无细胞基质片的主要成分。将同种异体来源内皮祖细胞培养增殖后植入血管无细胞基质，观察细胞生长情况，并进行血管无细胞基质动物毒性实验。拉力实验了解血管无细胞基质材料的收缩性能。 结果：颈动脉血管无细胞基质中已无细胞成分，无细胞基质主要由胶原成分组成。扫描电镜未见该材料表面存在细胞及细胞碎片，同时发现该无细胞基质存在孔隙样结构。体外同种异体来源的内皮祖细胞培养增殖后植入血管无细胞基质，细胞黏附于无细胞基质。血管无细胞基质按毒性分级属于无毒级。拉力实验说明该无细胞基质具有一定的韧性和牵张性。 结论：采用胰酶和十二烷基硫酸钠制备的颈动脉血管无细胞基质材料无细胞残留，具有一定的韧性和牵张性，种植于其中的种子细胞具备一定的生长能力。
