Co3O4 hollow spheres assembled from nanoparticles have been successfully synthesized by a one-pot hydrothermal carbonization and calcination method. In this method, carbon spheres obtained through hydrothermal carbonization at a low temperature of 140 ℃ are used as sacrificial templates. The carbonization process was monitored by Fourier transform infrared spectroscopy （FT-IR） and Raman spectroscopy. Both the carbon sphere soft templates and the NH3 released from hexamethylenetetramine play key roles in the formation of these novel hollow structures. The formation of the Co3O4 hollow spheres using hydrothermal carbon spheres as templates can be attributed to the synergetic effect of metal ion adsorption and heterogeneous nucleation of Co（OH）2, which is different from the traditional adsorption theory. The as-obtained Co3O4 hollow microspheres exhibit excellent cycling performance and good rate capacity when used as electrode materials in supercapacitors, which can be attributed to the small particle size of Co3O4 and the sufficient space available to interact with the electrolytes. This facile strategy may be extended to synthesize other metal oxide hollow spheres, which may find application in sensors and catalysts due to their unique structural features.

Acta Oceanologica Sinica 2000年第1期19卷 127-135页

作者： Zhu Changshou Huang Jiaqi Lin Junzhou du qinghong Chen Xu Li Shaojing (1. Fujian Institute of Oceanology, Xiamen 361012, China 2. Department of Oceanography, Xiamen University, Xiamen 361005, China) Fujian Institute of Oceanology Xiamen 361012 China Department of Oceanography Xiamen University Xiamen 361005 China

Based on the samples collected mesoplankton net from the south part Of Taiwan Strait (22. 25 --24. 65N, 117. 50 -- 120. 00E) in August 1997, 292 species of zooplankton and 11 groups of meroplankton were identified. In the survey waters, Copepoda was dominant in either species or individual numbers. The diversity (H' ) was 5. 11 and the ratio of diversity to evenness (J ) was 7. 10, showing that the diversity of zooplankton was exceedingly high in the survey waters. Three zooplankton communities were clearly divided by systematical cluster analysis, indicating that the biotopes of these zooplankton communities may serve as the evidence for the basic status of distribution of water masses during the investigation.

OBJECTIVE: To explore the effect of Tongluojiunao injection(TLJN) prepared with Sanqi(Radix Notoginseng) and Zhizi(Fructus Gardeniae) on the interaction between brain microvascular endothelial cells(BMECs) and astrocytes in an in vitro ischemic ***: First, an in vitro model of cerebral ischemia in BMECs or astrocytes was established by oxygen-glucose deprivation(OGD). TLJN was used as a medicine of intervention. The OGD-injuredBMECs were cultured in various astrocyte-conditioned media. Cell activity, alkaline phosphatase(AKP) and γ-glutamyl transpeptidase(γ-GT) activity,interleukin-1 beta(IL-1β), and tumor necrosis factor alpha(TNF-α) content in BMECs were ***, OGD-injured astrocytes were cultured in various BMEC-conditioned media. Cell activity, as well as expression of brain-derived neurotrophic factor(BDNF) and glial cell-derived neurotrophic factor(GDNF) in astrocytes, were ***: The results of paracrine signaling of normal BMECs or astrocytes showed a protective effect on each other: conditioned media from normal astrocytes improved cell viability, AKP, and γ-GT activity, and reduced IL-1β and TNF-α content of injured BMECs; conditioned media from normal BMECs improved cell viability and expression of BDNF and GDNF in injured astrocytes. However, once the BMECs or astrocytes were injured by OGD, the protective effect decreased or disappeared. The above-mentioned protective induction was effectively recovered by TLJN ***: The therapeutic benefit of TLJN was achieved by recovering two-way induction between BMECs and astrocytes, enhancing activity of injured BMECs and astrocytes, stabilizing enzymatic barriers, promoting expression of neurotrophic factors, and inhibiting inflammatory cytokines.

目的从下丘脑-垂体-肾上腺轴(hypothalamic pituitary adrenal axis, HPA)功能及神经递质含量变化探讨自拟安神方(简称安神方)对心肾不交证失眠大鼠的作用。方法复合因素刺激及腹腔注射DL-4-氯苯基丙氨酸(para-chlorophenylalanine, PCPA)制备心肾不交证失眠大鼠模型,造模成功后随机分为模型组,安神方高、中、低剂量组及阳性对照组,另设正常组每组各10只,分别灌胃相应药物2周。戊巴比妥钠翻正实验观察造模情况,旷场实验观察大鼠的紧张和焦虑情绪,Elisa法检测大鼠血清促肾上腺皮质激素(adrenocorticotropic hormone, ACTH)、促肾上腺皮质激素释放激素(corticotropin-releasing hormone, CRH)、皮质醇(cortisol, CORT)的含量,高效液相色谱-电化学法检测大鼠下丘脑中多巴胺(dopamine, DA)和5-羟色胺(5-hydroxytryptamine, 5-HT)的含量。结果造模后模型组大鼠体质量下降(P<0.05),睡眠潜伏期延长(P<0.01),睡眠持续时间显著减少(P<0.01),说明心肾不交证失眠模型复制成功。给药后安神方3剂量组大鼠2周体质量增量升高(P<0.05),直立次数减少(P<0.05),睡眠持续时间均显著延长(P<0.01),CRH含量降低(P<0.05),安神方低、中剂量组总活动距离减少(P<0.05);安神方中、高剂量组大鼠睡眠潜伏期均显著缩短(P<0.01),DA含量均降低(P<0.05);安神方低剂量组5-HT含量升高(P<0.05)。结论自拟安神方能显著改善心肾不交证大鼠的失眠症状,推测其机制可能与抑制HPA轴兴奋、降低下丘脑DA的含量、同时升高5-HT的含量有关。
