This paperindicated that it was good for condensation reaction when benzene-ring bearingelectron-attaching groups. It also showed that and the 6-hydroxyl group could bereacted with acyl halide, haloid ether and halo alkene, but not with halo alkane. It wasnot only the first time to find that the reaction product of D-mannitol and aromaticaldehyde is tri-condensation derivatives, but also the first time to obtain thep-phthaldehyde-sorbitol derivatives containing eight hydroxyl groups.

In this thesis, we describe a facile and economical synthesis of-abscisic acid from keto-isophorone and 3-butyn-2-ol through ketalization, oxidization, Witting-Horner reaction, reduction with chromium sulfate and other steps in 13% total yields. Compared to the previous routes, the starting materials are more commercially available and cheaper and the synthetic process is more easily controlled in our method, but the yield of this route is still to be improved.As to isostere principle, cyclopropyl and methyl vinyl are a couple of isostere.

We didn\'t find activated points in cerebellum and deeper brain.3.Acupuncture of sham point can significantly activated BA2,6,8,13,21,37,40,44,45,47,putamen and other areas.Both the left and right side of the brain have activated points,but points on the right side are more than those on the left.Both sides of middle temporal gyms,parietal lobule,supramarginal gyms and the lentiform nucleus have obvious activated points.The activated points mainly concentrated in the cerebral cortex,the deep-activated are mainly in the putamen.4. Sham needling in sham point can significantly activate BA6, 8,9,10,18,21,37,40,43,44.The activated points are mainly distributed in the right side of the brain.The left side also has some activated points;5.In the comparasion of Acupunture and sham-needling in S J5,we find that BA8 and cerebellum have distinct regional activated points;6.In the comparasion of acupuncture in SJ5 and sham point,we find BA2 and left cerebellar regions have activated points;7.Sham needling in S J5 compared with sham point,we find BA7,8,9,18 and other areas have activated points,the main activated points are at the left brain.It is not difficult to find that the distribution of activated points are mainly in the middle brain,no obvious activated points at the temporal lobe.

The study suggested that TNF〓 and IL-1〓 might be produced in the cascade of events resulting in Wallerian degeneration and hyperalgesia following peripheral nerve compression, and increased TNF〓 and IL-1〓 mRNA may trigger other later responses in nervous system contributing to the initiation of peripheral neuropathic pain or other degeneration/regeneration processes.
提示:外周神经受压后诸如华勒氏变性、痛觉过敏等一系列反应可能有TNF〓和IL-1〓的产生,而后者的增加又会启动其它神经反应而在外周神经源性痛形成和神经退变/再生中发挥作用。

The reasons for false-positive facet blocks are multifactorial and include placebo response (18–32%) to diagnostic facet interventions, use of sedation, the liberal use of superficial LA, and the spread of injectate to paingenerating structures other than those targeted.166 Although some investigators have disputed this assertion,167,168 it is our belief that not only opioids, but sedatives such as midazolam, can lead to false-positive blocks by interfering with the interpretation of analgesic response (i.e., preventing a patient from engaging in normal activities) and virtue of their muscle relaxant properties.169 In a recent survey conducted in 500 patients receiving facet blocks or epidurals at an outpatient spine center, only 17% requested sedation.170
小关节阻滞性诊断的假阳性结果的原因是多种多样的,包括安慰剂反应(18–32%),如利用镇静剂,浅表大量应用LA以及注射液外渗到目标外的其他疼痛发生阻滞。虽然有些学者对这种论断持怀疑态度,但是我们认为不论类罂粟碱,咪达唑仑等镇静剂,都可因具有麻醉反应(如可阻止患者从事正常活动)及肌松特点而导致假阳性率。在最近一项500人的研究中,这些门诊患者接受了小关节阻滞或硬膜外阻滞,只有17%患者需要镇静剂。
