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

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.

早期肠内复方谷氨酰胺在重症急性胰腺炎治疗中的应用疗效

目的:分析早期肠内复方谷氨酰胺在重症胰腺炎(severe acute pancreatitis,SAP)治疗中的应用疗效.方法:选取2012-01/2014-01青海红十字医院接收治疗的108例S A P患者.采用随机数表法将108例患者分为观察组和对照组,各54例.给予对照组患者早期肠内营养,给予观察组患者谷氨酰胺联合早期肠内营养.对比两组治疗后的疗效、肝肾功能和急性生理与慢性健康状况Ⅱ(acute physiology and chronic health evaluationⅡ,APACHEⅡ)评分,并比较两组患者治疗前后血清肿瘤坏死因子α(tumor necrosis factoral pha,TN F-α)、C反应蛋白(highsensitivity C-reactive protein,hs-CRP)、白介素1B(interleukin 1B,IL-1B)、IL-8、IL-6的水平.结果:治疗前两组患者的APACHEⅡ评分、谷丙转氨酶(alanine transaminase,ALT)、血尿素氮(blood urea nitrogen,BUN)、总胆红素(total bilirubin,TBIL)、谷草转氨酶(aspartate transaminase,AST)和Scr均高于治疗后,治疗后观察组患者的APACHEⅡ评分、ALT、BUN、TBIL、AST和Scr较对照组患者较低,比较两组间差异统计学具有意义(P0.05).治疗后两组患者的血清TNF-α、hs-CRP、IL-1B、IL-8、IL-6的水平与治疗前比较下降,IL-10升高,比较两组间差异统计学具有意义(P0.05).治疗后观察组患者的血清TNF-α、hs-CRP、IL-1B、IL-8、IL-6的水平均低于对照组患者,IL-10高于对照组患者,比较两组间差异统计学具有意义(P0.05).结论:早期肠内复方谷氨酰胺能够显著改善SAP患者的全身炎症状态,具有较好的临床疗效,可以在临床上进一步推广和使用.

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.
