目的 探讨晕可宁颗粒的主要药效学 ,为临床提供药效学资料及治疗学基础。方法 采用三氯甲烷破坏豚鼠一侧膜迷路感受器模型 ,探讨受试药对眼震颤、摆头及旋转的影响 ;采用内淋巴囊和内淋巴管阻塞手术复制豚鼠膜迷路实验性膜迷路积水模型 ,研究内耳组织平均中阶面积 (SMA)增加率及形态学的变化。结果 抑眩宁阳性对照组、晕可宁颗粒 (8、16g/kg)模型给药组豚鼠眼球震颤次数减少 ,差异有显著意义 (P <0 .0 5 )。成功复制了不同程度膜迷路积水豚鼠模型 ,表现为前庭膜重度膨出 ,前庭阶缩小 ,膜蜗管增大 ,SMA增加率变大 ,差异有显著意义 (P <0 .0 1) ;晕可宁颗粒灌胃后可减轻豚鼠实验性膜迷路积水的程度 ,差异有显著意义 (P <0 .0 1) ;但与空白对照组比较SMA增加率差异无显著意义 (P >0 .0 5 )。结论 晕可宁颗粒可以减轻内淋巴囊积水程度 ,对梅尼埃病症状有对抗治疗作用。 相似文献

The publication of the DSM-III rating scale in 1980 marked a definite turning point in the development of modern psychiatry. For those responsible for elaborating it, it appeared to have resulted in psychiatry being accepted as a science. However, this was at the expense of eliminating the subjective aspect, both that of the patient and that of the clinical practitioner. As a result of this, it was possible to utilize a common language which permitted high inter-scoring diagnostic accuracy. The success of the DMS-III and IV is based on their affinity with scientific ideals, and with their association with clinical medication. In focusing on target symptoms devoid of all dynamism, they implicitly relate them to bodily dysfunctions. Twenty years after the introduction of this approach presented as being atheoretical, its main justification, i.e. diagnostic accuracy, has been shown to be ill-founded, while the problems of diagnostic validity are eluded. The DSM scales have relegated mental disorders to being infinitized, and the pursuit of this approach could eventually lead to treatment by computerized psychiatry. These rating scales also lead to an impoverishment of clinical consultations; they do not take into account the possible reticence of the patient; and they generate implicit normative ideals. Even amongst their proponents, certain individuals are beginning to see that they could constitute a serious disadvantage to the progress of psychiatry. 相似文献

患者,男,41岁。全身弥漫性红斑伴严重瘙痒1年,多发淋巴结肿大3个月。PET/CT符合淋巴瘤;淋巴结病理:非霍奇金T细胞淋巴瘤,伴不规则、扭曲、脑回样核;皮肤病理:非霍奇金T细胞淋巴瘤,呈蕈样肉芽肿改变。结合患者症状、体征、影像学、病理及免疫组化结果,以及外周血T细胞基因重排均为阳性,诊断为Sézary综合征。给予化疗等一线药物治疗效果不佳。更换为含有维布妥昔单抗的治疗方案后患者红斑消退,瘙痒消失,淋巴结减小,达到完全缓解。 相似文献

目的 探讨肿瘤坏死因子受体相关因子6(TRAF6)对卡介苗(BCG)诱导巨噬细胞凋亡的调控作用。方法 Q-PCR检测活动性结核患者外周血中TRAF6的表达后利用不同感染复数的BCG感染RAW264.7细胞,在感染的不同时间通过Q-PCR和Western blot检测巨噬细胞中Caspase 3和TRAF6的表达。时间梯度试验处理组分为5组:对照组(未感染,C)、BCG感染6 h组、12 h组、18 h组和24 h组;感染复数试验处理组分为5组:对照组(未感染,C)、5 MOI组、10 MOI组、15 MOI组和20 MOI组。随后,通过小干扰RNA技术敲减RAW264.7细胞中TRAF6的表达,并结合BCG感染建立TRAF6敲减模型。TRAF6敲减实验分为4组:阴性对照组(NC)、BCG单独感染组(BCG)、TRAF6小干扰RNA单独处理组(siRNA)和TRAF6小干扰RNA与BCG共处理组(siRNA+BCG)。利用平板涂布法检测巨噬细胞菌载量变化。通过流式细胞术检测巨噬细胞凋亡率和线粒体膜电位变化。利用Western blot检测TRAF6、Caspase 3、PARP、Bcl-... 相似文献

Background and aimsIn type 2 diabetes (T2D) patients, the reduction of glycemic variability and postprandial glucose excursions is essential to limit diabetes complications, beyond HbA1c level. This study aimed at determining whether increasing the content of Slowly Digestible Starch (SDS) in T2D patients’ diet could reduce postprandial hyperglycemia and glycemic variability compared with a conventional low-SDS diet.Methods and resultsFor this randomized cross-over pilot study, 8 subjects with T2D consumed a controlled diet for one week, containing starchy products high or low in SDS. Glycemic variability parameters were evaluated using a Continuous Glucose Monitoring System.Glycemic variability was significantly lower during High-SDS diet compared to Low-SDS diet for MAGE (Mean Amplitude of Glycemic Excursions, p < 0.01), SD (Standard Deviation, p < 0.05), and CV (Coefficient of Variation, p < 0.01). The TIR (Time In Range) [140–180 mg/dL[ was significantly higher during High-SDS diet (p < 0.0001) whereas TIRs ≥180 mg/dL were significantly lower during High-SDS diet. Post-meals tAUC (total Area Under the Curve) were significantly lower during High-SDS diet.ConclusionOne week of High-SDS Diet in T2D patients significantly improves glycemic variability and reduces postprandial glycemic excursions. Modulation of starch digestibility in the diet could be used as a simple nutritional tool in T2D patients to improve daily glycemic control.Registration numberin clinicaltrials.gov: NCT 03289494. 相似文献
