??OBJECTIVE To study the protective effects of sparstolonin B(8,5'-dihydroxy-4-phenyl-5,2'-oxidoisocoumarin,SsnB) on mouse with intracerebral haemorrhage(ICH). METHODS The effect of SsnB on neuronal cell death induced by Hb using a microglia-neuron transwell system was investigated. Autologous nonanticoagulated blood was collected from the tail artery of the mouse and then injected into the striatum using a syringe pump. Neurological deficit of the mouse with ICH was assessed 1, 3, 5 and 7 d after SsnB administration using modified neurological severity score system,and brain water content of the mouse cerebral tissues after ICH was measured at the same day. The concentrations of pro-inflammatory cytokines in perihematoma tissues, including interleukin-6, interleukin-1?? and tumor necrosis factor-??, were measured by ELISA assay. RESULTS The RESULTS show that SsnB significantly reduced the neurological deficit scores and the brain water content, and inhibited the levels of IL-6, IL-1?? and TNF-?? at first day and third day after ICH. CONCLUSION SsnB can improve the brain injury in mouse induced by ICH. The mechanism may involve increased the neuronal survival rate and decreased expression of pro-inflammatory cytokines of mouse after ICH. 相似文献

??OBJECTIVE To evaluate the safety of medication of vitamin B6. METHODS Clinical studies involving vitamin B6 were searched from PUBMED, EMBASE, Cochrane Library(2014,06) , LILACS and four Chinese databases, CBM,CNKI,VIP and WANFANG. National drug administration websites were also been searched. Two authors independently extracted and evaluated the included studies.Causality assessment of an adverse drug event was performed with the WHO-UMC system. RESULTS A total of 2 582 literatures were searched and 27 were included involving 805 patients. Randomized controlled trials concluded that there was no significant difference between oral use of vitamin B6 and comparison group in the incidence of adverse event. Cohort studies concluded that there was no dose-response relationship between oral vitamin B6 30-230 mg and adverse drug reaction.Case series studies, case reports and websites information concluded that the most common adverse reactions of vitamin B6 were numbness and other peripheral neuropathy.CONCLUSION Serious adverse drug reactions may occur irrespective of oral and intravenous use of vitamin B6, such as drug-induced liver damage and allergic shock. Common adverse reactions such as peripheral neuropathy needed to be closely monitored especially when overdose used. 相似文献

目的:比较腹部B超与阴道B超诊断异位妊娠的价值。方法:65例异位妊娠患者分别先后予以腹部B超与阴道B超检查,分析两种检查方式的诊断结果并与手术病理学结果进行比较,探讨两种检查方式对异位妊娠的诊断率率。结果:阴道B超的阳性确诊率为95.38%,高于腹部B超的78.46%,差异具有统计学意义(P0.05)。阴道B超对胚芽、盆腔积液、附件包块、假孕囊及心血管搏动的检出率显著高于腹部B超,差异具有统计学意义(P0.05)。结论:阴道B超诊断异位妊娠的阳性检出率明显高于腹部B超,能够减少漏诊、误诊率,且阴道B超具有简便、直观的优点。 相似文献

目的:探讨腹部B超联合阴道B超诊断方法在妇产科急腹症临床诊断中的应用价值。方法:选取本院接诊的127例急腹症患者,以手术病理学的结果作为诊断金标准,采用单纯腹部B超检查及其与阴道B超联合检查,对比2种诊断方法的应用效果,并对2种诊断方法的结果进行统计学处理。结果:经阴道及腹部超声联合检查的准确率94.48%显著高于单纯腹部检查的准确率75.59%,组间比较,差异具有统计学意义(P0.05)。结论:腹部B超联合阴道B超诊断方法对妇科急腹症进行临床检查,大大提高超声诊断的准确率。 相似文献
