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。     

Dose reduction for the management of indinavir-related toxicity in human immunodeficiency virus type 1-infected patients in Taiwan: clinical and pharmacokinetic assessment.

This study evaluated the feasibility of reducing the indinavir (IDV) dosage in Taiwanese patients receiving the standard IDV/ritonavir (RTV) dosage of 800/100 mg twice a day who had undetectable plasma human immunodeficiency virus type 1 (HIV-1) RNA but had developed IDV-related toxicities. After dosage reduction to IDV/RTV 600/100 mg twice a day, the dose-related toxicity decreased and plasma HIV RNA remained undetectable at 24 weeks post-switch in all patients. The maximal plasma concentration (Cmax) and area under the plasma concentration-time curve of IDV decreased significantly (median, 6.3 vs 4.3 microg/mL and 1892 vs 1292 microg.min/mL, p=0.01 and 0.001, respectively) but the minimal plasma concentration remained at a similar level (median, 1.0 vs 0.8 microg/mL, p=0.12). This study found that the reduction in the dosage of IDV in HIV-1 infected patients receiving the standard IDV/RTV regimen guided by therapeutic drug monitoring decreased the Cmax, dose-related toxicity and medical cost without compromising viral control.     

Inhibition of the ubiquitin-proteasome system: a new avenue for atherosclerosis.

BACKGROUND: The ubiquitin-proteasome system (UPS) is thought to be functionally active in atherosclerosis (AS) lesions. Aspirin was found to be a potent inhibitor of the UPS in some tumour studies; however, its effect on AS remains to be demonstrated in vivo. METHODS: New Zealand rabbits were placed on a normal diet (N) or on a normal diet with aspirin (NI) or on an atherogenic diet without (H) or with aspirin (HI) for 12 weeks. Proteasome activity, concentrations of plasma lipids and levels of peroxidation were determined. Ubiquitin/ubiquitin-conjugates (Ub), IkappaBalpha, phosphorylated IkappaB (pIkappaBalpha) and p65 were investigated by Western blotting or immunochemistry. RESULTS: Concentrations of plasma lipids and peroxidation levels were higher in H or HI vs. N or NI. Histological analysis showed that atheroma was increased in H. Ub and IkappaBalpha were mainly localised in subendothelium and media vascular smooth muscle cells. Western blots revealed that Ub, IkappaBalpha, and pIkappaBalpha were increased, whereas p65 was lower in HI vs. H. The activity of the 20S proteasome was functionally active in H vs. N, NI or HI, while the 26S proteasome was not affected in any of the groups. CONCLUSIONS: Aspirin can attenuate the pathogenesis of atheroma formation, the degradation of IkappaBalpha and pIkappaBalpha, and lower the expression of p65, indicating that its therapeutic effects on AS may be via inhibition of the UPS.     

腹茧症7例临床分析

目的:探讨腹茧症病因诊断和治疗的方法.方法:对2004～2006年住院7例腹茧症患者的临床资料进行回顾性分析.结果:6例有外科急腹症的表现,术前分别诊断为:消化道穿孔、十二指肠淤滞症、盆腔囊肿、盆腔子宫内膜异位症、原因不明的急性肠梗阻;另1例行胃癌手术时发现本病.7例术前均未明确诊断,经手术证实为腹茧症.术后全部治愈出院,随访无复发. 结论:腹茧症临床表现不典型,诊断困难,误诊率高,确诊需剖腹探查和病理切片.纤维包膜切除术和肠粘连松解术是治疗本病的有效方法.     

大脑中动脉支架内血栓形成1例报告

支架内血栓形成是支架置入术后的一种常见并发症。术后血管内皮损伤、胶原组织暴露和作为异物的支架均为引发血栓形成的可能机制。不能及时识别处理则成为再狭窄的重要原因。我们报告1例发生在大脑中动脉（middle cerebral artery，MCA）支架内的血栓形成，探讨其识别处理过程和可能的机制。     

通心络胶囊对冠状动脉扩张症的治疗价值

腹腔镜与开腹直肠癌低位前切除术后吻合口瘘发生率的比较

目的探讨腹腔镜与开腹直肠癌低位前切除术后吻合口瘘发生率的差异。方法2000年9月至2005年12月由同一组医师连续对距肛缘5～8cm的直肠癌患者实施腹腔镜下根治术(LP术组)53例及传统开腹根治术135例,比较两组和两组内患者造口与未造口者发生吻合口瘘的差异。结果LP术组造口与未造口者吻合口瘘的发生率分别为4.6%(1/22)与6.5%(2/31),χ~2=0.088,P>0.05;差异无统计学意义。OP术组造口与未造口者吻合口瘘的发生率分别为2.3% (1/43)与8.7%(8/92),χ~2=1.024,P>0.05;差异无统计学意义。LP术组与OP术组行造口的患者吻合口瘘发生率比较,P=0.455,差异无统计学意义;LP术组与OP术组未行造口者的吻合口瘘发生率比较,P=0.288,差异也无统计学意义。结论腹腔镜行直肠癌低位前切除术与开腹手术相比,不会增加吻合口痿的发生率。
