| 3 | Effect of compound preparation Tongqiao Jiannao capsules on neural cell apoptosis and Bcl-2 and Bax protein levels in a rat model of brain ischemia/reperfusion injury显示文摘BACKGROUND:Pharmacological studies have demonstrated that compound preparation Tongqiao Jiannao capsules composed of Zexie, Baizhu, Honghua, Danshen, and Shexiang can supplement qi, activate blood circulation, relieve blood stasis, induce resuscitation for alleviating pain, relieve pain, and dilate blood vessels. OBJECTIVE: To observe the effects of Tongqiao Jiannao capsules on the levels of the anti-apoptotic protein Bcl-2 and the proapoptotic protein Bax, and verify the mechanism of action. DESIGN, TIME AND SETTING: Randomized, controlled animal experiment, performed in the Laboratory of Biochemistry and Molecular Biology, Shanxi Medical University between June 2001 and December 2002. MATERIALS: The right middle cerebral arteries of 24 healthy adult Sprague Dawley rats were occluded by the suture method. The primary Chinese herbal medicinal ingredients of Tongqiao Jiannao capsules are Zexie, Baizhu, Honghua, Danshen, and Shexiang, which were purchased from Shanxi Provincial Medicinal Material Company, China, and prepared into condensed granules in the Room for Chinese Herbal Medicine Preparation, Second Hospital, Shanxi Medical University. Bcl-2 and Bax immunohistochemical staining kits, a 3,3-diaminobenzidine(DAB) kit, and an in situ apoptosis detection kit were purchased from Wuhan Boster Bioengineering Co., Ltd., China. METHODS: Twenty-four rats were randomly and evenly divided into three groups: (1) sham-operated rats in which sutures were inserted and immediately pulled out; (2) Tongqiao Jiannao capsule-treated rats that were intragastrically administered 6.5 g/kg/d Tongqiao Jiannao capsule preparation for seven successive days prior to middle cerebral artery occlusion (MCAO); and (3) MCAO rats without any other treatments. MAIN OUTCOME MEASURES: The levels of neural cell apoptosis and Bcl-2 and Bax proteins at 24 hours post-surgery. RESULTS: In the MCAO group, the numbers of apoptotic cells and Bax-positive cells were significantly increased, while the numbers of Bcl-2-positive cells were slightly decreased compared with the sham-operated group. Bcl-2- and Bax-positive cells and apoptotic cells were primarily distributed in the ischemic penumbra. In the Tongqiao Jiannao capsule-treated group, neuronal apoptosis was inhibited, and the number of Bcl-2-positive cells was significantly increased (P < 0.01), while the number of Bax-positive cells was significantly decreased (P < 0.01), compared with the MCAO group. CONCLUSION: Tongqiao Jiannao capsules elevated Bcl-2 expression, lowered Bax expression, and inhibited cellular apoptosis during the process of cerebral ischemia/reperfusion injury. | Rui Wang Guanglai Li Wei Wang Huanying Li | 2008 | Neural Regeneration Research2008,3,8: | 1 |
| 4 | Artificial and Semi-artificial Photosynthesis(AP and SAP)Systems Based on Metal-Organic Frameworks显示文摘Recently,artificial and semi-artificial photosynthesis have attracted extensive attentions in addressing the crisis of energy from fossil fuels and reducing excessive CO_(2) emission.Metal-organic frameworks(MOFs)have been considered as ideal platforms for constructing artificial photosynthesis systems due to their unique properties like large specific surface area,high porosity and diverse framework topology,and tunable functionalities.This review discussed the characteristics,superiorities and challenges of MOF-based photocatalysts,and detailed summarization of several common design strategies for MOF-based artificial systems,including i)enhancement of light absorption,ii)acceleration of the charge separation and transfer,and iii)introduction of additional active units.Particularly,we give examples showing the applications of MOF-based photocatalysts,where the mechanisms of superior photocatalytic activity and selectivity are also analyzed,thereby providing theoretical guidance for rational design of MOF-based photocatalysts.Finally,the challenges and future research directions of MOF-based photocatalysts are prospected. | Guanglai Mo Qiao Wang Wanyue Lu Chen Wang Peng Li | 2023 | Chinese Journal of Chemistry2023,41,3: | 0 |
| 5 | Laser photolysis of ionic liquid [bmim][PF_6]显示文摘Photoinduced chemical reactions of 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF_6]) were studied by laser photolysis at a wavelength of 266 nm.Excited triplet state ~3[bmim]^+ was observed,radical cation [bmim]^(2+) and neutral [bmim] radical via photoionization were also formed.Energy transfer from ~3[bmim]^+ toβ-carotene was confirmed.Oxidation via one electron transfer from TMPD to ~3[bmim]^+ was also observed and the rate constant was determined to be 1.2×10.5 L.mol^(-1).s^(-1).The reaction of [bmim][PF_6] with hydrated electron (e_(aq)) was confirmed by laser photolysis in aqueous solution. | ZHU Guanglai WU Guozhong LONG Dewu YAO Side | 2007 | Nuclear Science and Techniques2007,18,1: | 0 |
