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。     

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.     

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。     

Correlation between levels of serum immunoglobulin、complement and immunopathology in glomerular disease

目的 探讨肾小球疾病免疫球蛋白、补体水平与免疫病理的相关性.方法 112 例肾小球疾病患者,14 例健康人测定血清免疫球蛋白及补体,112 例肾小球疾病患者,112 例患者行肾活组织病理检查.结果 112 例肾小球疾病患者 IgG 升高 11 例(9.82%),降低 29 例(25.89%),IgA 升高 33 例(29.46%),降低 2 例(1.79%).IgM 升高 7 例(6.25%),降低 3 例(2.68%),三种免疫球蛋白的变化有显著差异(x2=70.587,P=O.000);C3 减低 29 例(25.89%),C4减低 32 例(28.57%),两者比较无显著差异(X2=0.203,P=0.653).免疫荧光阳性率依次为C3(50%)>lgA(49.11%)>IgG(40.18%)>lgM(21.43%)>C4(14.29%)(x2=49.303,P=0.000);免疫荧光 IgA 阳性者血清 lgA 水平较阴性者高(P=0.042),C3、CA阳性者血清 C3、c4 水平较阴性者低(P=0,P=0.007),IgG、IgM 阳性者血清 IgG、lgM 水平与阴性者比较无差异(P=0.136,P=0.383).结论 肾小球疾病存在体液免疫紊乱,测定血清免疫球蛋白、补体及行肾组织免疫病检有助于了解体液免疫状况,估计疾病活动度,判断疗效,但两种检查之间无明显的相关性,可相互补充,不能相互替代.     

The action of(±)-MDMA on medial prefrontal cortical neurons is mediated through the serotonergic system

The mechanism of action of systemitically administered(±)-MDMA (3, 4-methylenedioxymethamphetamine) on spontaneously active neurons in the medial prefrontal cortex (mPFc) of chloral hydrate anesthetized rats was examined using standard single unit extracellular recording techniques. Intravenously administered MDMA dose-dependently decreased the firing rates of the majority of mPFc neurons in control rats. In contrast, in rats that were pretreated withp-chlorophenylalanine (PCPA), which depletes the brain serotonin (5-hydroxytryptamine, 5-HT) content by inhibiting tryptophan hydroxylase, the rate-limiting enzyme in the synthesis of 5-HT, MDMA was largely ineffective in inhibiting the firing of mPFc cells. In PCPA-treated animals, the administration of 5-hydroxytryptophan (5-HTP), which presumably restored the brain 5-HT content, but notl-DOPA, reinstated MDMA's inhibitory action in PCPA-treated rats. In rats that were pretreated withα-methyl-p-tyrosine (AMPT), which depletes the brain dopamine (DA) content by inhibiting tyrosine hydroxylase, the rate-limiting enzyme in the synthesis of DA, MDMA inhibited the firing of all of the mPFc cells. MDMA's effect on mPFc neurons was reversed by 5-HT receptor antagonists such as granisetron and metergoline. These results strongly suggest that MDMA exerts its action on mPFc cells indirectly by releasing endogenous 5-HT.
