2017年许昌市居民慢性病防治素养水平现状分析

目的了解许昌市居民慢性病防治素养水平现状,为制定慢性病健康促进与健康教育措施提供理论依据。方法采用多阶段分层整群抽样和随机抽样结合进行抽样,对许昌市城乡非集体居住的15～69岁常住人口进行居民健康素养问卷调查。结果 2017年共调查全市15～69岁常住人口3 704人,收回有效问卷3 687份,有效率为99.54%。加权后,2017年许昌市居民慢性病防治素养水平为11.05%。单因素分析显示,城乡分布、不同年龄、文化程度、职业的居民慢性病防治素养水平差异有统计学意义。城市居民为16.95%,高于农村居民的9.25%。工人和农民最低,分别为6.92%和6.39%。15～24岁组最高,为15.39%;65～69岁组最低,为3.01%。大专/本科及以上组最高,为32.75%;小学及以下组最低,为4.44%。居民慢性病防治素养水平呈现出随着年龄增加而降低、随学历升高而升高的分布特点。结论许昌市居民慢性病防治素养处于较低水平,应倡导多部门、多专业、多学科协作,大力普及慢性病防治相关知识和技能,提高居民慢性病防治素养水平,同时积极探索针对中老年人和低文化程度人群的慢性病防治健康教育形式。

血必净注射液对呼吸机相关性肺炎的影响

目的:观察血必净注射液对呼吸机相关性肺炎(VAP)的影响,探索较单用抗菌药物更有效的治疗方法。方法:选择2006-2013年我院老年病科VAP 51例。治疗组26例在应用抗菌药物基础上给予血必净注射液静脉滴注。对照组25例单用抗菌药物治疗。结果:治疗组的VAP总有效率65.38%,对照组为44.00%,两组比较有显著性差异(P<0.01)。治疗组抗菌药物平均使用时间8天,对照组抗菌药物平均使用时间10天,两组比较差异显著(P<0.05)。治疗期间未发现治疗组有明显副作用,包括皮肤过敏、出血等。结论:抗菌药物联合血必净注射液治疗VAP疗效肯定,有效缩短了抗菌药物的使用时间,减少了抗菌药物用量,值得临床推广。     

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).

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.
