目的环氧合酶是广泛表达于大脑各区域的一类同功酶,主要用于治疗疼痛与炎症。最近研究还发现环氧合酶在大脑相关疾病的病理生理过程中扮演关键角色。本文运用慢性压力动物模型,对环氧合酶抑制剂的保护作用做一探讨。方法每只小鼠每天被迫游泳 6 min,共持续 15 天。结束后进行行为学(包括活动能力、焦虑以及记忆能力)和生化指标(包括脂质过氧化、亚硝酸盐水平、还原性型谷胱甘肽和过氧化氢酶水平)的检测。结果持续15天的强迫性游泳会损伤小鼠活动能力,引起焦虑样行为的产生,并削弱记忆力。在生化指标方面,脂质过氧化和亚硝酸盐水平均显著提高,还原型谷胱甘肽和过氧化氢酶活力则显著降低。此外,环氧合酶抑制剂,包括甲氧萘丙酸、罗非考昔、美洛昔康、尼美舒利和伐地考昔,都能显著减缓这些损伤。结论环氧合酶抑制剂可被用来治疗慢性疲劳综合症。

目的环氧和酶(COX)抑制剂和脂肪氧化酶(LOX)抑制剂已被证实具有神经保护作用,但对其具体机制目前研究甚少。喹啉酸具有兴奋毒性作用,通过激活NMDA受体,引起类似于亨廷顿舞蹈症(Huntington’s Disease,HD)的症状,包括行为、形态以及生化水平上的各种异常。本研究旨在探讨咖啡酸(LOX特异性抑制剂)和罗非考昔(COX特异性抑制剂)各自以及两者连用对喹啉酸引起的大鼠神经毒性的改善和修复作用。方法在大鼠右侧纹状体内注射喹啉酸,诱导神经毒性。随后每天给大鼠口服咖啡酸或罗非考昔,或两者同时服用。用一系列行为学及生化检测方法检测咖啡酸和罗非考昔,以及两者连用对喹啉酸诱导的大鼠行为变化及谷胱甘肽氧化还原紊乱的改善和修复作用。结果在纹状体注射喹啉酸不仅能降低大鼠体重,引起运动失调,而且能破坏纹状体内氧化还原间的平衡,表现为谷胱甘肽水平降低,以及氧化谷胱甘肽水平升高。长期服用咖啡酸或罗非考昔,以及两者连用都能显著减轻喹啉酸引起的行为变化,修复氧化还原水平的平衡。而当剂量为2.5mg/kg时,咖啡酸未表现出任何保护作用。结论本实验结果表明,大脑的兴奋性中毒有可能通过改变谷胱甘肽的水平影响氧化与抗氧化间的平衡。环氧合酶和脂肪氧化酶通路都可能参与了喹啉酸诱导的神经毒性过程。这些结果为治疗HD提供了研究靶点。

作者： kumar puneet Gupta 重庆医科大学

学位级别：硕士

OBJECTIVE: The aim of this study was to investigate the differences in the time and image quality of reconstructed cerebral angiograms between volume CT digital subtraction angiography （VCTDSA） and conventional CT angiography（CTA） with bone elimination technique. MATERIALS AND METHODS: Thirty-two patients with cerebrovascular diseases, who underwent VCTDSA in our department, were further remodeled cerebral vessels with both VCTDSA and conventional CTA. Cerebral vessels were displayed with 3D volume rendering （3D VR） and 3D maximum intensity projection （3D MIP）, respectively. The post-processing time and the image quality were then compared. RESULTS: The image quality with VCTDSA vessel reconstruction was excellent. Compared with conventional CTA, VCTDSA had an advantage in displaying the integrity of vessels, the range of intracranial arteries and veins, and also in lessening the remained high density shadows （ p＜0.001）. The time of post-processing by VCTDSA （mean: 6.87±2.96 min） was much shorter than that of conventional CTA （mean: 14.37±1.66 min）（ p＜0.001）. There was a significant positive correlation between the post-processing time and the subtraction image quality with VCTDSA （ r=0.79, p＜0.001）. CONCLUSION: VCTDSA is a fast, accurate and feasible method for the sensitive assessment of cerebrovascular structures and can be used as a powerful tool in the diagnosis of cerebrovascular diseases. Compared with conventional CTA, VCTDSA has an advantage in displaying the integrity of vessels, the range of intracranial arteries and veins, and also in lessening the remained high density shadow. The post-processing time of VCTDSA is significant shorter than that of conventional CTA.

Journal of Tuberculosis Research 2017年第2期5卷 118-128页

Introduction: Reports indicate that fluorescent staining of smears increases sensitivity of direct microscopy;so ZN staining is being replaced with fluorescent microscopy in RNTCP in India. Chemical processing and sputum concentration may also improve sensitivity of microscopy. Objective: To compare the sensitivity and specificity of microscopy for AFB using ZN and fluorescent stains in direct and concentrated specimen with culture as gold standard. Methods: Morning sputum specimen of patients, suspected of having pulmonary tuberculosis, over a period of 6 months was subjected to direct microscopy using fluorescent stain;the same slide was over-stained with ZN stain. Same sputum sample was concentrated by Petroff’s method and subjected to fluorescent microscopy followed by ZN microscopy and finally to culture for AFB. Results: Sensitivity of fluorescent stained concentrated sputum samples was maximum and of ZN stained unprocessed sputum samples was minimum. Specificity of three of the methods was equal at 0.96 but of ZN stained concentrated sputum smears was 0.97. Sensitivity of total fluorescent stains was 0.85 (Specificity 0.96) and sensitivity of total ZN stained smears was 0.80 (Specificity 0.96). Discussion: We used same smear for fluorescent and ZN stains, so smear related variability is decreased. Blinding for microscopy was practically complete. Conclusion: The sensitivity of sputum microscopy for AFB can be increased by concentrating the sputum and using fluorescent microscopy. The specificity remains high in all the methods.
