To integrate a terahertz pump into an ultrafast electron diffraction(UED)experiment has attracted much attention due to its potential to initiate and detect the structural dynamics both ***,the deflection of the electron probe by the electromagnetic field of the terahertz pump alters the incident angle of the electron probe on the sample,impeding it from recording structural information *** this article,we studied this issue by a theoretical simulation of the terahertz-induced deflection effect on the electron probe,and came up with several possible schemes to reduce such *** a result,a terahertz-pump-electron-probe UED experiment with a temporal resolution comparable to the terahertz period is *** also found that Me V UED was more suitable for such terahertz pump experiment.

OBJECTIVE: To investigate the effects of Gubi prescription on the expression of caveolin-1, and the phosphoinositide 3 kinase/protein kinase B(PI3 K/Akt) and Fas signal pathways in rats with knee osteoarthritis(KOA).METHODS: Forty KOA model rats were established using a modification of Hulth's method. Rats were divided into five groups by the random number method: model, positive drug(Vicolli group), and high-, medium-, and low-dose Gubi prescription groups(n = 8/group). In the sham surgery group(n = 8), only anterior and posterior cruciate ligaments of rats were exposed during surgery. A normal group(n = 8) consisted of rats with no treatment. Rats were intragastrically administered corresponding drugs once every day for eight consecutive weeks. Then, rat synovial membranes were extracted and histomorphological changes were recorded. m RNA expression was measured by *** superoxide dismutase(SOD), malondialdehyde(MDA), nitric oxide(NO), and interleukin 1β(IL-1β) levels were measured. Western blotting determined the effects of Gubi prescription on protein expressions of caveolin-1, Bax, Bcl-2, Fas, and caspase-3 in chondrocytes from KOA rats. The knee cartilage of rats was excised and cultured under aseptic conditions. After coincubation of chondrocytes with Gubi prescription-containing serum, IL-1β, and si RNA, Western blotting was used to determine the protein expressions of caveolin-1, Bax, Bcl-2, Fas, and ***: The morphological score of the articular synovium in the model group was significantly higher than in the normal group(P < 0.01). The morphological score in the high-and mediumdose Gubi prescription groups was lower than in the model group(P < 0.05). Chondrocytes from the decoction-containing serum group had a lower expression of Bax(P < 0.05), and higher expressions of Bcl-2(P < 0.05) and caspase-3(P < 0.05) compared with the model group. Chondrocytes in the decoction-containing serum group had higher expressions of Bax and Bcl-2(P <

目的探讨脂肪干细胞(ADSC)对脑缺血大鼠梗死灶周围组织轴索生长抑制因子A(Nogo-A)表达的影响。方法分离培养大鼠ADSC,线栓法制作大鼠大脑中动脉栓塞模型。大鼠分为假手术组、模型组和ADSC组。ADSC组于造模成功1 d后侧脑室注射ADSC悬液,模型组注射PBS。各组分别于术后4 d、7 d和14 d分批处死,采用反转录PCR检测梗死灶周围组织Nogo-A mRNA水平、免疫组织化学染色法和Western blot法检测梗死灶周围组织Nogo-A蛋白水平。结果与假手术组相比,模型组和ADSC组各个时间点梗死灶周围组织Nogo-A表达水平明显增加;ADSC组各个时间点梗死灶周围组织Nogo-A表达水平较模型组明显降低。结论 ADSC移植可有效抑制脑缺血后大鼠梗死灶周围组织Nogo-A的表达从而促进神经功能的恢复。
