    • 摘要: GATA4,as a member of the GATA transcription factor family,plays a significant role in lineage specification and trans-differentiation of cells by regulating target gene expression.In this study,the potential transcription factor binding sites in the pro-moter of Paralichthys olivaceus sox2 gene were analyzed,and a GATA4-binding motif was identified.A cleaved amplified poly-morphic sequence-based binding assay experiment was performed,and the results showed a significant binding process between the Homo sapiens GATA4 recombinant protein and the DNA fragment of P.olivaceus sox2 promoter.Luciferase reporter assay revealed that GATA4 could improve the activity of the P.olivaceus sox2 promoter.Overexpression of P.olivaceus GATA4 could also increase the sox2 mRNA expression level in flounder brain cells.Overall,our results indicate that sox2 is a target gene of GATA4 in P.oliva-ceus.Sox2 is implicated in the maintenance of stem cell pluripotency and can reprogram differentiated cells to iPS cells.In addition,sox2 is involved in the development of the central nervous system(CNS).Therefore,this study may provide a reference for exploring the function of P.olivaceus GATA4 in the regulation of pluripotent stem cells and the development of the CNS.

    • 摘要: 采用简易水解法制备了一系列CNs−Bi_(12)O_(17)Cl_(2)复合半导体材料并对其物相、光学性质和光催化降解性能进行了分析表征。X射线衍射光谱表明复合体系衍射峰与四方晶相Bi_(12)O_(17)Cl_(2)一致,紫外可见漫反射光谱证明复合材料在可见区域具有较强的光吸收能力,由此可提高光催化活性。在可见光照射下,复合体系相对于纯Bi_(12)O_(17)Cl_(2)对亚甲基蓝具有更高的降解效率,特别是具有合适组分的样品CB50可以在180 min后完全去除20 mg·L^(−1)的亚甲基蓝分子,这主要是由于CNs的引入抑制了光生载流子的复合,使复合体系表现出更高的光催化降解性能。最后,提出了可能的光催化机理。

    • 摘要: 采用序批式活性污泥反应器(ASBR),通过调整进水C/N和S/N,在活性污泥体系中探究电子受体有限的条件下,不同电子供体(有机物或者S2-)对反硝化和硝酸盐氮异化还原成铵(DNRA)过程的影响.结果 表明:较高的C/N进水条件,有利于反硝化过程的进行;而较高的S/N进水条件,更有利于DNRA过程的发生;DNRA过程的特征产物NH4+-N,在C/N/S=2:2:3、2:2:4条件下的出水中较明显,其中C/N/S=2:2:4条件下,NH4+-N浓度达到最高为10.65mg/L.说明在电子受体有限时,过量的电子供体可促使反硝化向DNRA过程转变.采用16SrRNA分子生物学技术对不同C/N/S下的微生物菌群结构进行分析,发现与氮还原相关的Proteobacteria、Anaerolineae、Bacteroidia、Actinobacteria等菌群丰度较高,且Actinobacteria菌与DNRA过程相关.不同电子供体环境下氮转移途径的研究可为污水处理过程中碳,氮,硫的同步去除提供指导.

    • 摘要: 通过对现有文献中有关护士岗位胜任力要素的文章进行系统综述,以期为构建中国特色专科护士(clinical nurse specialist,CNS)岗位胜任力评价体系提供依据。综述结果表明,国内CNS岗位胜任力研究处于初级阶段,研究工具较多,评价标准不一,影响因素研究多为横断面调查,目前的研究结果只供参考,缺乏纵向研究及针对影响因素的干预研究。CNS胜任力的提高需要参考不同层级的培训需求,制定相应的胜任力标准。国外有关CNS岗位胜任力的研究较为成熟,可借鉴国外经验,依据中国国情,统一我国CNS岗位胜任力标准,基于CNS岗位胜任力需求进行临床干预,提高我国临床CNS的岗位胜任力。

    • 摘要: Objective To evaluate the clinical features of primary Sj?gren's syndrome(pSS)patients with CNS inflammatory demyelination.Methods The clinical data of 8 pSS patients with CNS inflammatory demyelination were analyzed retrospectively.Results Neurological symptoms preceded the diagnosis of pSS in 7 patients.Three patients had brain involvement and 5 patients had spinal cord involvement.Among the 3 patients with brain involvement,one patients who presented with dizziness,diplopia,dysphagia and difficult walking had demyelination lesions from medulla to C2.One patient with hearing loss and tinnitus had demyelination lesions in deep white matter of frontotemporal and parietal lobe.One patient presented with slow mental reaction and hearing loss, whose MR showed demyelination lesions in deep white matter of bilateral frontal and parietal lobe.Five patients had spinal cord involvement and the lesions predominantly located in cervical and thoracic cords.Two patients with blurred vision and myelitis underwent serum and cerebrospinal fluid inspection for anti -aquaporin-4(AQP4)antibody, which showed positive results.Among the 8 cases, except for one abandoning treatment, seven cases received treatment, five of them had good response while the other two had no obvious response.Conclusions Patients with CNS inflammatory demyelination should be screen for systemic autoimmune disease, such as pSS.If pSS patients present typical optic neuritis and longitudinal extensive transverse myelitis, AQP4 antibody is supposed to be done for diagnosis of neuromyelitis optica.%目的 探讨伴有CNS炎性脱髓鞘的原发性干燥综合征(pSS)的临床特点.方法 回顾性分析8例诊断明确的伴有CNS炎性脱髓鞘的pSS患者的临床资料.结果 8例患者中7例以CNS症状表现为首发症状.在3例出现脑损害症状的患者中,1例表现为头晕、视物重影、饮水呛咳、行走困难,其病灶位于延髓至颈髓C2段脱髓鞘病灶;1例表现为听力下降、耳鸣,病灶位于双侧额颞顶深部白质脱髓鞘病灶;1例表现为反应迟钝、听力下降,头颅MRI示双侧额顶叶深部多发脱髓鞘病灶.其余5例均为脊髓损害症状患者,单纯颈髓受累1例,单纯胸髓受累1例,颈胸腰骶髓受累1例,颈胸髓同时受累1例,胸腰段受累伴左侧颞极病灶1例.2例脊髓炎患者行血清水通道蛋白4(AQP4)抗体检测为阳性.8例患者中1例患者放弃治疗,7例患者接受治疗,其中5例好转,2例无明显疗效.结论 在CNS脱髓鞘的患者中应注意筛查是否合并系统性疾病如pSS等,在pSS患者中若出现视神经脊髓炎典型表现应查AQP4抗体以尽早诊断是否二者共病.

    • 摘要: Trachysperum ammi has been traditionally used for the treatment of neurological disorders such as depression and anxiety. To date, T. ammi has reported for its chemical constituents in different diseases condition. The traditional evidence convinced us to perform the antidepressant-like activity of methanolic extract of Trachysperum ammi (META). The antidepressant activity of META assessed by using forced swimming test (FST), tail suspension test (TST), and locomotor activity test. The seed parts of META at doses level of 50, 100 and 200 mg/kg body weight administered orally to examine the CNS stimulants activity test in mice behavioral models. Here, we reported that META significantly reduced immobility time in the FST after repeated administration of 50, 100 and 200 mg/kg to mice for 14 days. The intensity of immobility significantly reduced at all of the doses (p < 0.05) whereas, we were found the strongest effect observed at 200 mg/kg. The antidepressant-like effect of META caused the reduction (p < 0.05) in the immobility in TST of mice when orally administered with 50, 100 and 200 mg/kg for 14 days, respectively. Additionally, we were executed locomotor activity test to check the motor stimulating activity. META has employed at a dosage of 50, 100 and 200 mg/kg for 14 days, the results have found that 50 mg/kg produced the locomotion effects as similar to the control group. Interestingly, the locomotion, rearing, and defecation significantly (p < 0.05) increased at the dosage of 100 and 200 mg/kg of META. Our present findings suggest that the seed parts of Trachysperum ammi may possess antidepressant-like activity which may use as a supportive treatment to management of neurological disorders.
