"心主神明"与"脑主神明"的再认识

首先分析了诸家对“心主神明”与“脑主神明”争论所存在的误区；其次阐明了“心主神明”并非《内经》原旨以及“神”、“神明”、“神志”的内涵；并揭示了“心神”与“脑神”的关系及其实质；最后结论说明“神明”之争是无价值的。心神说和脑神说可在“神经-内分泌-免疫网络”理论中获得完美的结合。

丰城鸡血藤中刺芒柄花素的大鼠肠吸收研究

利用大鼠在体单向肠灌流模型,采用HPLC测定灌流液中刺芒柄花素含量,分别考察刺芒柄花素质量浓度、不同肠段以及P-糖蛋白抑制剂对刺芒柄花素肠吸收的影响,得出丰城鸡血藤中刺芒柄花素在大鼠体内的肠吸收机制。实验结果显示灌流液中刺芒柄花素质量浓度对吸收速率常数(K_a)和表观吸收系数(P_app)均无显著性影响;刺芒柄花素在小肠段(十二指肠、空肠和回肠)的K_a和P_app无显著性差异显著,但其K_a显著大于在结肠处的值(P<0.05),小肠段和结肠段的P_app无显著性差异;P-糖蛋白抑制剂维拉帕米对刺芒柄花素在各肠段的K_a和P_app均有显著性差异(P<0.05)。表明刺芒柄花素在大鼠肠道内的吸收机制为被动扩散,不存在饱和吸收;其在全肠段的吸收较好,吸收窗主要在小肠,且小肠内无明显的特定吸收部位;刺芒柄花素可能是P-糖蛋白的底物。     

17-氢-9-去氢穿心莲内酯体外代谢速率及代谢产物研究

应用体外大鼠肝微粒体孵育体系,研究喜炎平注射液中主要有效成分17-氢-9-去氢穿心莲内酯(DHA)的体外代谢速率及代谢产物。将17-氢-9-去氢穿心莲内酯与加入NADPH的大鼠肝微粒体共同孵育,采用超高效液相色谱-三重四极杆串联质谱法(UHPLC-MS/MS)测定其剩余浓度,考察17-氢-9-去氢穿心莲内酯的肝微粒体代谢速率,并采用超高效液相色谱串联飞行时间质谱(UPLC-TOF-MS^E)对孵育体系中17-氢-9-去氢穿心莲内酯的代谢产物进行鉴定。研究结果显示在加入辅酶的大鼠肝微粒体中,17-氢-9-去氢穿心莲内酯代谢速率较快,其半衰期(t_1/2)和肝微粒体中清除率(CL)分别为(19.7±0.5) min和(35.1±0.8) mL·min^-1·g^-1。高分辨质谱数据结合文献信息共鉴定孵育体系中17-氢-9-去氢穿心莲内酯的9个代谢产物,主要为羟基化产物和脱氢产物。鉴定结果为筛选出活性更好的穿心莲二萜内酯类衍生物提供了一定的依据。     

药用植物金荞麦的光合特性研究

目的:研究金荞麦叶片的光合特性,为提高金荞麦的产量和质量提供依据。方法:自然条件下利用LI-6400型便携式光合系统测定金荞麦品种贵州Ⅰ号和江苏Ⅱ号孕蕾期叶片的光响应及光合日变化进程。结果:金荞麦叶片的光响应曲线符合非直角双曲线方程,贵州Ⅰ号金荞麦的光饱和点和光补偿点均高于江苏Ⅱ号金荞麦,对环境的适应能力较强。金荞麦叶片的净光合速率、光合有效辐射、蒸腾速率和气孔导度的日变化曲线均呈单峰曲线,不存在明显的"午休"现象。相关性分析表明,金荞麦叶片净光合速率与气孔导度、光合有效辐射、蒸腾速率和水分利用效率等呈正相关,与胞间CO2浓度呈负相关。结论:金荞麦为阳生植物,气孔导度、光合有效辐射和蒸腾速率是影响金荞麦叶片净光合速率的主要环境因子。

Preseptostomy Myocardial Infarction in a Patient with Complex Transposition of the Great Arteries

In transposition of the great arteries, systemic venous return is preferentially routed to the aorta, and any spontaneous or iatrogenic emboli may therefore cause organ infarction. We present a patient with transposition of the great arteries who developed myocardial infarction prior to balloon septostomy and, also, was later documented to have sustained brain infarction despite adequate precautionary measures. Minimal handling of venous sites in these patients is crucial.     

Mortality among persons with a history of Kawasaki disease in Japan: Can paediatricians safely discontinue follow-up of children with a history of the disease but without cardiac sequelae?

Aim: To clarify the question of whether patients with Kawasaki disease suffer a higher mortality rate after the incidence of the disease in comparison with age-matched healthy individuals. Methods: Between July 1982 and December 1992, 52 collaborating hospitals collected data on all patients having a new, definite diagnosis of Kawasaki disease. Patients were followed up until 31 December 2001 or their death. The expected number of deaths was calculated from Japanese vital statistics data and compared with the observed number. Results: Of 6576 patients enrolled, 29 (20 males and 9 females) died. The standardized mortality ratio (SMR: the observed number of deaths divided by the expected number of deaths based on the vital statistics in Japan) was 1.15 (95% CI: 0.77-1.66). In spite of the high SMRs during the acute phase, the mortality rate was not high after the acute phase for the entire group of patients. Although the SMR after the acute phase was 0.75 for those without cardiac sequelae, six males (but none of the females) with cardiac sequelae died during this period; and the SMR for the male group with cardiac sequelae was 1.95 (95% CI: 0.71-4.25). The mortality from congenital anomalies of the circulatory system was elevated, but no increase in cancer deaths was observed.

Conclusion: Although it was not statistically significant, the mortality rate among males with cardiac sequelae due to Kawasaki disease appeared to be higher than in the general population. On the other hand, the mortality rates for females with the sequelae and both males and females without sequelae were not elevated.
