城乡发展一体化视野的社会主义新农村建设

随着改革的深化,市场导向的资源配置以及与其相联系的劳动力、土地、资金等生产要素持续“农转非“,许多地区在城镇化进程中出现了“农村空心化、农业副业化、劳力老龄化“,城乡不协调的问题越来越尖锐。如何应对这一严峻挑战是摆在我们面前的重大课题。实践经验表明,只有把城镇的有形城市化与农村的无形城市化有机结合起来,城乡差别才会逐步缩小,城镇化才能持续健康发展。新农村应当是向城镇化方向发展的农村;城镇化应当是带动农村相应发展的城镇化。城镇化的目标不是要消灭农村,而是实现城乡发展一体化。社会主义新农村建设应当是“物的新农村“和“人的新农村“建设齐头并进

我国农村经济制度创新理性思考

伴随着我国工业化、城镇化深入推进,农业、农村发展正在进入新的阶段,经济社会结构的深刻变化对创新农村经济制度提出亟待破解的课题。客观上要求全面构建农业生产经营、农业支持保护、农民财产权、农村金融服务以及城乡协调发展的制度框架,进一步解放和发展农村社会生产力,全面繁荣农村经济,加快城镇化进程,顺利跨越“中等收入陷阱“

干扰司法独立的外部因素——浅谈政党干预与司法独立

行政机关以及国家权力机关干预司法已成为社会重点关注的问题,在倡导司法独立的过程中必须搞清楚行政权力机关是如何干预司法的,又是为何干预司法的。正确设置政党对司法的有限干预是我们司法独立工作中得以深入开展的重中之重

谈WTO多哈回合谈判与中国的国家定位

WTO多哈回合谈判拉锯至今分歧根源在于全球区域经济发展的不平衡以及各国基于本国经济结构而在国际经济交往中的利益诉求不同。现今国际社会仍然缺乏一套“硬性“的国际经济法律支撑,因此争端会表现为集团政治力量之博弈。在此过程中,我国应当以现实为基础,放眼未来经济发展趋势,走“南北逢源“的中间定位

Experimental Study on the Effect of Sanchong Banxia Baizhu Tianma Decoction on the Expression of 5-HT1B/1D Receptor in the Brain of Rats with Migraine

目的探索三虫半夏白术天麻汤治疗偏头痛的作用机制。方法建立硝酸甘油致大鼠偏头痛模型,给予半夏白术天麻汤高、中、低剂量灌胃干预7 d,以苯甲酸利扎曲普坦为西药阳性对照药物,并予空白组、模型组进行对照。运用RT-PCR检测5羟色胺1B、1D(5-HT1B/1D)受体的基因表达。结果 1)对5-HT1B受体表达的影响:与空白组相比,模型组显著低于空白组(P0.05),中药中剂量组、中药高剂量组、西药组及联合用药组显著低于空白组(P0.05)。2)对5-HT1D受体表达的影响:与空白组相比,中药中剂量组显著降低(P0.05);与模型组相比,各组无显著差异(P>0.05);与中药中剂量组相比,空白组、中药低剂量组、西药组、联合用药组较中药中剂量组显著升高(P0.05)。结论 5-HT1B/1D受体调节异常为偏头痛的发病环节之一。三虫半夏白术天麻汤可以提高偏头痛大鼠脑组织5-HT1B受体的基因表达,对5-HT1D受体的基因表达具有双向调节作用,临床运用,剂量不宜过大。Objective: To explore the mechanism of Sanchong Banxia Baizhu Tianma Decoction in the treatment of migraine. Methods: Migraine model of SD rats were set up with nitroglycerin,given Banxiabaizhutianma decoction of high,medium and low-dose intervention respectively for 7 days,taking Rizatriptan Monobenzoate as a positive control drug medicine,compared with the blank control group and the model group. RT-PCR was used to test the genetic expression of the 5-HT1 B receptor and the 5-HT1 D receptor. Results: The influence on the expression of the 5-HT1 B receptor: compared with the blank control group,the model group was significantly lower than the control group(P 0.05);traditional Chinese medicine medium dose group,high dose group,western medicine group and the combination group were significantly lower than the blank control group(P 0.05). The influence on the expression of 5-HT1 D receptor:compared with the blank control group,traditional Chinese medicine medium dose group decreased significantly(P 0.05);compared with the model group,there was no significant differ ence among them(P > 0.05);compared with the traditional Chinese medicine medium dose group,the blank control group,traditional Chinese medicine low dose group,western medicine group and combination group were significantly higher(P 0.05). Conclusion: 5-HT1B/1D receptor dysregulation is one cause of the pathogenesis of migraine. Sanchong banxia baizhu tianma decoction can improve the genetic expression of 5-HT1 B receptors in migraine rats′ brains,and has a dual-direction regulation on genetic expression of the 5-HT1 D receptors. In the field of clinical application,the dose should not be too large.2012福建省中医药科研课题(wst201211

Experimental Study on the Basic Effect of Huatan Anshen Decoction and on Orexin Expression in Hypothalamus of Insomnia Rats

目的：研究化痰安神方治疗失眠症的药效学基础及其对失眠大鼠下丘脑食欲素表达的影响,揭示本方部分药效学机制。方法：通过小鼠自发活动实验、戊巴比妥钠阈下及阈上睡眠协同实验探索化痰安神方治疗失眠症的药效学基础;通过对氯苯丙氨酸（PCPA）制造失眠大鼠模型,分为中药组、西药组、空白组、模型组,每组干预7天,使用免疫组化检测实验大鼠下丘脑食欲素（Orexin）。结果：（1）化痰安神方可抑制小鼠自发活动,与空白组比较,具有显著差异（P〈0.01）;（2）对戊巴比妥钠阈下入睡率的影响：中药组、对照组、西药组实验小鼠入睡率分别为：65%、72%和100%,西药组入睡率明显高于中药组、对照组（P〈0.01）;睡眠持续时间,中药组长于西药组（P〉0.05）,西药组长于对照组（P〈0.05）;（3）对戊巴比妥钠阈上睡眠情况的影响：中药组睡眠持续时间明显长于西药组（P〈0.01）,西药组长于对照组（P〈0.01）;（4）对氯苯丙氨酸（PCPA）致失眠大鼠各组下丘脑食欲素表达水平无差异（P〉0.05）。结论：化痰安神方具有一定的镇静催眠作用,可明显延长失眠患者的持续睡眠时间,其作用机理可能不是通过调节食欲素水平这一途径。Objective： To study the basic effect of Huatan Anshen decoction and the effect on orexin expressions in Hypothalamus of insomnia rats and reveal the partial pharmacodynamics mechanism. Methods： Spontaneous activity in mice and synergistic action test of pentobarbital sodium were observed to study the basic effect of Huatan Anshen decoction. The second part, through para chlorophenylalanine （PCPA） making rat model of insomnia, divided into Chinese medicine group and Western medicine group, blank group, model group, each group of rats were intervened for 7 days, Hypothalamus Orexin was detected by immunohistochemisty. Results： （1） Huatan Anshen Decoction can inhibit the spontaneous activity of mice, compared with the control group, with significant difference （P〈0.01）. （2） Effect on the rate of sleep pentobarbital sodium： Chinese medicine group and control group, western medicine group mice sleep rates were： 65%, 72% and 100%. The rate of western medicine group was significantly higher than that of traditional Chinese medicine group and control group （P〈0.01）. Sleep duration： Chinese medicine group was longer than the western medicine group （P〈0.05）, the western medicine group was longer than the control group （P〈0.05）. （3）Sleep duration of Chinese medicine group was significantly longer than the western medicine group （P〈0.01）, and the western medicine group was significantly longer than the control group（P〈0.01）. （4） There was no difference in the expression level of orexin （P〈0.05） in the hypothalamus of insomnia rats induced by phenylalanine （PCPA）. Conclusion： Huatan Anshen decoction has sedative and hypnotic effects, can prolong the duration of sleep in patients withinsomnia. The mechanism of Huatan Anshen decoction to prolong the duration of sleep in patients with insomnia may not be regulated by the level of orexin pathways.2013福建省中医药科研课题（批准号：wzln201311
