2490名中老年干部钙化性主动脉瓣病的患病情况及超声心动图分析

本文分析了在2490名中老年干部中经超声心动图诊断的104例钙化性主动脉瓣病的超声心动图表现。发现其患病率随年龄增长成倍数递增,男性多于女性。该病不仅可以引起众所周知的AS,也可引起AI,以无冠瓣受累最多。轻—中度CAS及CAI尚不足以引起心脏解剖结构的明显改变,左室收缩功能也保持正常,但舒张功能却发生障碍。     

Resistance to toxin-mediated fungal infection: role of lignins,isoflavones, other seed phenolics,sugars, and boron in the mechanism of resistance to charcoal rot disease in soybean

Charcoal rot disease in soybean is caused by the fungus Macrophomina phaseolina, which is believed to infect plants from soil through the roots by a toxin-mediated mechanism. Soybean genotypes exist which are susceptible (S) or moderately resistant (MR) to charcoal rot, but the mechanism of resistance is not known. Significantly (p ≤ 0.05) higher levels of phenolics, seed coat lignin, isoflavones, sugars, and total boron were observed in MR genotype than in S genotype seeds under irrigated and nonirrigated and under experimental M. phaseolina infested and noninfested conditions, indicating a possible association of these substances with resistance to toxin-mediated infection.     

实验性急性肺血栓栓塞症肺动脉血管重构及意义

目的：探讨急性肺血栓栓塞症肺动脉血管重构及其临床意义。方法：取栓塞3～24h后的急性肺血栓栓塞症动物模型的栓塞段肺动脉，同时取正常肺动脉设实验对照组，固定液固定后送检。结果：正常肺动脉内皮细胞完整，未见平滑肌细胞迁移，肌层平滑肌呈层状，多为收缩型；肺栓塞后，肺动脉内皮细胞脱落，中层平滑肌细胞向内皮迁移，可见较多的合成型平滑肌细胞，内皮下可见类凋亡平滑肌细胞。结论：急性肺栓塞后，栓塞段肺动脉局部发生血管重构．对肺动脉高压的产生可能起着一定作用。

Inhibitory Effects of Eucommia ulmoides Oliv. Bark on Scopolamine-Induced Learning and Memory Deficits in Mice

Eucommia ulmoides Oliv. Bark (EUE) is commonly used for the treatment of hypertension, rheumatoid arthritis, lumbago, and ischialgia as well as to promote longevity. In this study, we tested the effects of EUE aqueous extract in graded doses to protect and enhance cognition in scopolamine-induced learning and memory impairments in mice. EUE significantly improved the impairment of short-term or working memory induced by scopolamine in the Y-maze and significantly reversed learning and memory deficits in mice as measured by the passive avoidance and Morris water maze tests. One day after the last trial session of the Morris water maze test (probe trial session), EUE dramatically increased the latency time in the target quadrant in a dose-dependent manner. Furthermore, EUE significantly inhibited acetylcholinesterase (AChE) and thiobarbituric acid reactive substance (TBARS) activities in the hippocampus and frontal cortex in a dose-dependent manner. EUE also markedly increased brain-derived neurotrophic factor (BDNF) and phosphorylation of cAMP element binding protein (CREB) in the hippocampus of scopolamine-induced mice. Based on these findings, we suggest that EUE may be useful for the treatment of cognitive deficits, and that the beneficial effects of EUE are mediated, in part, by cholinergic signaling enhancement and/or protection.     

脐带血有核细胞移植治疗肌萎缩侧索硬化的临床研究

目的观察脐带血有核细胞治疗肌萎缩侧索硬化（ALS）的疗效并探讨机制。方法采集新生儿脐带血,获取含干细胞的有核细胞混悬液,每份平均含有核细胞4.29×108个,通过腰椎穿刺,将其移植入蛛网膜下腔。结果移植后第5天患者单手握力较移植前平均增加1.68 kg;移植后第1个月94.46%患者病情好转;第2个月5.12%持续好转,73.04%保持稳定;第3个月36.06%保持稳定;第4个月18.85%保持稳定;第5个月10.61%保持稳定。结论脐带血有核细胞蛛网膜下腔移植在一定时间内可有效缓解ALS的临床症状。     

右旋兰索拉唑的药理学特点及在胃食管反流病治疗中的应用

虽然质子泵抑制剂(PPI)在胃食管反流病(GERD)治疗方面取得了很大的成功,但是抑酸时间不足、患者依从性差等挑战仍然存在。近期,美国FDA批准了一种新的PPI药物右旋兰索拉唑(dexlanso-prazole,日本武田公司开发,商品名:DexliantTM),目前主要用于糜烂性食管炎急性期及维持期的治疗,以及非糜烂性胃食管反流疾病烧心症状的控制。该药物采用独特的双层缓释技术,可以维持更长的作用时间,达到更好的抑酸效果,且安全性和耐受性良好。
