1例遗传性血色病继发糖尿病患者的护理

正遗传性血色病(HHC,HH),是常染色体隐性遗传疾病;因铁代谢相关基因发生突变,所编码的蛋白功能发生改变,导致体内铁吸收过多、排出减少,使组织器官中铁质进行性沉积,导致脏器功能损害,产生肝硬化、糖尿病、心肌病、心律失常、性功能减退、关节炎、皮肤色素沉着等临床病症~([1,2])。流行病学调查发现, 有20%～50% 的遗传性血色病(GH) 患者同时伴有糖尿病~([3])。HH通常在40～50岁发病,在欧洲、美洲白人中常见,男性发病率高于女性,北欧患

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).     

Glial regenerative response in the imaginal discs of Drosophila melanogaster

<正>Glial cells play a key role during nervous system development and actively participate in all the cellular processes involved in maintaining its structural robustness and functional plasticity.In response to neuronal damage,glial cells proliferate,migrate to the injured region and change their morphology,function,and behavior     

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.

CT联合MRI用于子宫内膜癌分期诊断的临床价值探讨

目的 分析研究CT联合MRI用于子宫内膜癌分期诊断的临床价值.方法 选取我院在2016年1月~2016年10月收治的60例子宫内膜癌患者作为本次的研究对象,将其按入院时间分为观察组与对照组,每组30例患者.给予对照组患者实施CT诊断,观察组患者在对照组患者的基础上加用MRI进行诊断.观察对比两组患者的分期诊断确诊率.结果 观察组患者的分期诊断确诊率为86.67%,对照组患者的分期诊断确诊率为60.00%,两组相比,差异显著,且P<0.05,具有统计学意义.结论 在子宫内膜癌的分期诊断中,使用CT联合MRI进行诊断,能够显著提高患者的确诊率,对患者往后的治疗有着重要的意义,其所得的数据具有较高的临床价值,值得各大医院进行推广和实行.
