In this study, we synthesized (±)-tylophorine malate (NK-007), an analog of tylophorine (DCB3503), and analyzed its anti-inflammatory effect in vivo using a dextran sulfate sodium (DSS)-induced colitis model and an acetic acid-induced colitis model. As indicated by disease activity index (DAI) and degree of macroscopic colonic damage, NK-007 can significantly suppress colitis. To delineate the underlying mechanism, we have explored the influence of NK-007 on the production of TNF-α by murine primary bone marrow-derived dendritic cells (BMDCs) as well as monocyte/macrophage cell line Raw 264.7 triggered by lipopolysaccharide (LPS). For both types of innate immune cells, NK-007 showed a potent TNF-α inhibitory effect, and has in addition reduced the expression of IL-12 in BMDCs. Moreover, Raw cells treated with NK-007 also showed decreased phosphorylation of NF-κB, which may explain the protective immune-regulatory effect of NK-007 for experimental colitis. 相似文献

Boron neutron capture therapy (BNCT) is a tumor-selective radiation therapy using α and 7Li particles, which are produced by the reaction of neutron with boron (10B), and taken up by the tumor. The authors report their first experience of BNCT on a patient with no history of surgery, chemotherapy or conventional radiotherapy for papillary cystadenocarcinoma in the upper lip. 相似文献

目的:了解结核患者自我效能感与社会支持的现状并分析其相关性。方法:采用一般资料问卷、慢性病自我效能量表(Self-Efficacy for Managing Chronic Disease 6-Item Scale,SECD6)和肖水源研发的社会支持量表(Social Sating Rating Scale,SSRS)对154名结核患者进行问卷调查,并对二者进行Pearson相关性分析。结果:本组结核患者的自我效能总分为36.41±13.97,其中症状管理得分为24.40±9.84,疾病共性管理得分为12.01±5.48,社会支持总分为36.86±8.74,其中客观支持得分为7.73±2.57,主观支持得分为21.97±6.63,利用度得分为7.16±1.98。Pearson相关分析结果显示:结核病患者社会支持与自我效能感总分呈正相关(r=0.565,P<0.001)。结论:结核患者的自我效能和社会支持均处于中等水平,社会支持与自我效能呈密切相关。建议护理人员采取知识宣教、患者互助、医患交流、亲属陪护等多方面的干预措施,以增加患者的自我效能。 相似文献

Attachment style is a relatively stable trait linked to emotion regulation and coping as measured by questionnaire responses. An increasing number of functional brain imaging studies have explored the neural underpinnings of attachment style during emotional processing. However, until now, an overall picture of brain regions involved in this trait remained unexplored. Here, we conducted a meta-analysis of 12 peer-reviewed studies on attachment style using activation likelihood estimation (ALE) in functional magnetic resonance imaging (fMRI). We observed a significant negative correlation between avoidance attachment scores and activation of left inferior frontal gyrus to emotional stimuli, implying an inhibition processing for emotional stimuli in people with high avoidance attachment. In addition, there was a significant positive correlation between anxiety attachment scores and activation of left amygdala during emotional processing, which suggested an increased vigilance to emotional stimuli. 相似文献

Non-suicidal self-injury (NSSI) is a significant behavioral problem among adolescents all over the world. This study examined the longitudinal relationship between peer victimization and NSSI, as well as the buffering effects of self-compassion and family cohesion on this relationship. Data were collected at two time points from 525 secondary school students (226 girls; Mage = 12.97, SD = 1.02) in China. Results showed that peer victimization (marginally) significantly predicted NSSI over time even after controlling for Wave 1 NSSI. This association was weakened under the condition of high levels of self-compassion. Findings of this study emphasize the buffering effect of self-compassion in the relationship between peer victimization and NSSI, and are informative for prevention and intervention of this behavioral problem. 相似文献

The present study was aimed to evaluate the effect of apigenin 8-C-glucoside (Vitexin) and chlorogenic acid on epileptic mice induced by pilocarpine and explored its possible mechanisms. Intraperitonial administration of pilocarpine (85 mg/kg) induced seizure in mice was assessed by behavior observations, which is significantly (p > 0.05) reduced by apigenin 8-C-glucoside (AP8CG) (10 mg/kg) and chlorogenic acid (CA) (5 mg/kg), similar to diazepam. Seizure was accompanied by an imbalance in the levels of Gamma-aminobutyric acid (GABA) and glutamate in the pilocarpine administered group. Moreover, convulsion along with reduced acetylcholinesterase, increased monoamine oxidase and oxidative stress was observed in epileptic mice brain. AP8CG and CA significantly restored back to normal levels even at lower doses. Further, increased lipid peroxidation and nitrite content was also significantly attenuated by AP8CG and CA. However, CA was found to be more effective when compared to AP8CG. In addition, the mRNA expression of N-methyl-d-aspartate receptor (NMDAR), mGluR1 and mGlu5 was significantly (P ≤ 0.05) inhibited by AP8CG and CA in a lower dose. The mRNA expression of GRIK1 did not differ significantly in any of the group and showed a similar pattern of expression. Our result shows that AP8CG and CA selectively inhibit NMDAR, mGluR1 and mGlu5 expression. Modification in the provoked NMDAR calcium response coupled with neuronal death. Hence, these findings underline that the polyphenolics, AP8CG and CA have exerted antiepileptic and neuroprotective activity by suppressing glutamate receptors. 相似文献

Paroxysmal kinesigenic dyskinesia is a rare disorder, and there are few reports of Asian patients with this condition. We reviewed the clinical features of all patients with idiopathic paroxysmal kinesigenic dyskinesia (PKD) seen at a major neurological centre in Malaysia. The charts of 11 patients with idiopathic PKD seen between 1995 and 2008 were reviewed retrospectively. The male:female ratio was 9:2. Ten patients were of Chinese ethnicity, and one was Malay. Three patients (from two families) had a family history of PKD. The involuntary movement was dystonia in 73% of patients. In one patient, attacks were precipitated by vestibular stimulation. One patient had generalized epilepsy. Another patient who did not have epilepsy demonstrated epileptiform discharges. Only slightly over one-quarter of patients had a positive family history. Males, and people of Chinese ancestry, seem to be affected more frequently by PKD in certain Asian populations. 相似文献
