黄精多糖对新生大鼠大脑皮层神经细胞缺氧性凋亡的影响

目的:探讨黄精多糖对体外培养的新生大鼠大脑皮层神经细胞缺氧性凋亡的保护作用.方法:采用"Neurobasal加B27 Supplement"体外培养新生大鼠大脑皮层神经细胞,使用Hoechst 33342荧光染色、免疫细胞化学染色观察黄精多糖对缺氧复氧性神经细胞凋亡的保护作用.结果:缺氧前加入500μg/ml～1.5mg/ml的黄精多糖能显著地降低缺氧复氧培养诱导的神经细胞凋亡率,增加缺氧的神经细胞Bcl-2蛋白的表达,减少Bax蛋白的表达,提高Bcl-2/Bax比值.而缺氧12h后加入黄精多糖则无明显的抗凋亡作用.结论:缺氧前加入黄精多糖可以通过上调缺氧神经细胞Bcl-2表达、下调Bax表达和提高Bcl-2/Bax的比值以避免缺氧的神经细胞凋亡.

姜昧草的化学成分研究

姜味草Micromeria biflora Benth．为唇形科植物，全草具有类似生姜的气味，故称姜味草。本品始载明朝《滇南本草》，是云南常用中草药，资源丰富，能温中散寒、理气止痛，嫩枝叶作药茶还可预防感冒。有关文献报道含有挥发油，为进一步开发利用云南丰富的姜味草资源，本实验研究了其非挥发性部分的化学成分。从姜味草全草的乙醇提取物中，用硅胶柱色谱分离得到6个成分，

CT引导下带钩钢丝术前定位在胸腔镜下孤立性肺小结节切除术中的应用

Objective Video-assisted thoracoscopic surgery (VATS) provides a minimally invasive approach to resect small solitary pulmonary nodules (SSPN). The aim of this study is to evaluate the efficacy and safety of preoperative CT-guided hookwire localization for SSPN in VATS. Methods Hookwire was used to localize 26 SSPN under CT guidance in 24 patients (14 male, 10 female, age range 21-61 years, mean 52.3 years), preoperatively, and wedge resection was performed through VATS. The lesion size, distance from the lesion to parietal pleura, the time of localization and complications were evaluated. Results All the 26 pulmonary nodules were preoperatively detected and localized with hookwire under CT-guidance. The mean lesion size was 10.05 ± 3.08 nun in diameter, and the mean distance from lesion to parietal pleura was 10.09±2. 62 mm. The mean localization time was 20. 18±7.16 min, and then the nodules were removed by VATS within 18 ± 6. 65 min. The major complication of CT-guided hookwire localization was mild pneumothorax in 6 patients (25.0%), but no one needed chest tube drainage. The dislodgment of hookwire was found in only one patient (4.2%) during the operation, but the lesion was still successfully resected under VATS. Of those patients, 8 were confirmed to have a primary NSCLC by rapid pathologic diagnosis during VATS wedge resection, and then VATS lobectomies were performed. Condusion The preoperative CT-guided hookwire localization for small solitary pulmonary nodules is an effective and safe technique to assist VATS resection of the nodules.
