慢性萎缩性胃炎伴上皮内瘤变人群中医体质分布研究

目的?分析慢性萎缩性胃炎（CAG）伴上皮内瘤人群中医体质分布规律。方法?回顾性分析2015年2月1日—2017年12月31日在福建中医药大学附属第二人民医院门诊及体检中心行胃镜检查的CAG伴上皮内瘤变受试者及单纯CAG受试者资料，将240例CAG伴上皮内瘤变受试者作为研究组，240例单纯CAG受试者作为对照组，收集患者一般信息、发病部位、中医体质结果等信息，分析不同年龄CAG伴上皮内瘤变发生率与性别的关系，分析性别、年龄、CAG伴上皮内瘤变发生部位与中医体质分布情况的关系，比较CAG伴上皮内瘤变和单纯CAG的中医体质分布情况。结果?240例CAG伴上皮内瘤变患者，不同年龄组CAG伴上皮内瘤变发生率差异有统计学意义（P<0.05），56~65岁年龄段发病多见。CAG伴上皮内瘤变体质分布（兼挟体质纳入其中）：血瘀质27例，湿热质100例，气郁质60例，阴虚质33例，痰湿质38例，气虚质45例，阳虚质48例，平和质5例，特禀质5例，以湿热质为主。男性人群以湿热质为主，其次是痰湿质和气郁质；女性人群中以气郁质、气虚质为主，其次是阳虚质。湿热质（11.6%）好发于45~55岁年龄段，气郁质（7.8%）、痰湿质（4.4%）和气虚质（5.3%）好发于56~65岁年龄段，阴虚质（3.6%）、阳虚质（6.6%）好发于>65岁年龄段。CAG伴上皮内瘤变质发生部位以胃窦为主，其次是胃体、胃角，发生部位和体质分布差异无统计学意义（P>0.05）。CAG伴上皮内瘤变人群以湿热质为主，其次是气郁质，然后是阳虚质和气虚质。单纯萎缩性胃炎也是以湿热质为主，其次是阳虚质、气虚质、气郁质。两组间体质分布差异有统计学意义（P<0.05）。结论?CAG伴上皮内瘤变人群中，男性发病率较女性高，发病年龄段中老年人多见，男性人群体质以湿热质为多，女性人群以气郁质、气虚质为主。发病部位与中医体质无明显相关性，CAG伴上皮内瘤变和单纯CAG体质分布具有明显差异。

Significant impact of cryopreserved amniotic membrane on acute ocular Stevens-Johnson syndrome and toxic epidermal necrolysis

The ocular surface is covered by an epithelium encompassing an area including the cornea,the limbus and the conjunctiva bordered by the upper and lower lids.The healthy state of the ocular surface epithelium depends on a stable and protective preocular tear film when the eye is open.A stable preocular tear film is governed by sound ocular surface defense that involves effective neuroanatomic integration of compositional and hydrodynamic factors by two neural reflexes (1).     

人格特质对二胎返岗护士产适应水平的影响

目的 了解二胎返岗护士适应水平现状,并探讨人格特质对其返岗适应水平的影响。方法 2018年1-12月,采用便利抽样法选取山东省3所三级甲等医院360名护士为研究对象,采用一般资料调查表、艾森克人格问卷、护士产后返岗适应问卷对其进行调查。结果 护士产二胎后返岗适应水平均分为(2.16±0.51)分;外向型人格特征与返岗适应水平呈正相关(r=0.540,P<0.001),精神质、神经质人格特征与返岗适应水平均呈负相关(r=-0.410,P<0.001;r=-0.350,P<0.001)。多元线性回归分析结果显示,年龄、返岗时间、工作负荷、返岗培训、内-外倾向、精神质、神经质是护士产二胎后返岗适应的独立影响因素。结论 护士产二胎后返岗适应处于中等偏下水平,人格特质、生育年龄、返岗时间、工作负荷、返岗培训为其影响因素,护理管理者可结合人格特质等特点采取管理策略,提高护士产二胎后返岗适应的水平。

Tandem pore TWIK-related potassium channels and neuroprotection

TWIK-related potassium channels(TREK) belong to a subfamily of the two-pore domain potassium channels family with three members, TREK1, TREK2 and TWIK-related arachidonic acid-activated potassium channels. The two-pore domain potassium channels is the last big family of channels being discovered, therefore it is not surprising that most of the information we know about TREK channels predominantly comes from the study of heterologously expressed channels. Notwithstanding, in this review we pay special attention to the limited amount of information available on native TREK-like channels and real neurons in relation to neuroprotection. Mainly we focus on the role of free fatty acids, lysophospholipids and other neuroprotective agents like riluzole in the modulation of TREK channels, emphasizing on how important this modulation may be for the development of new therapies against neuropathic pain, depression, schizophrenia, epilepsy, ischemia and cardiac complications.
