抗心磷脂抗体、抗β_(2)糖蛋白Ⅰ抗体与不明原因胚胎反复种植失败相关性分析

目的探讨抗心磷脂抗体(ACA-IgM;ACA-IgG)、抗β_(2)糖蛋白Ⅰ抗体(A-β_(2)GPI-IgM;A-β_(2)GPI-IgG)与不明原因胚胎反复种植失败的相关性。方法回顾性分析北部战区总医院2019年1—12月收治的不明原因胚胎反复种植失败的218例患者(B组)和接受胚胎移植且临床确定妊娠的321例孕妇(A组)的临床资料。记录两组研究对象的一般资料,并比较ACAIgM、ACA-IgG、A-β_(2)GPI-IgM、A-β_(2)GPI-IgG阳性率。结果A组ACA-IgM、ACA-IgG、A-β_(2)GPI-IgM、A-β_(2)GPI-IgG阳性率分别为3.11%(10/321)、4.67%(15/321)、1.87%(6/321)、1.56%(5/321),B组分别为6.88%(15/218)、8.25%(18/218)、3.66%(8/218)、3.21%(7/218)。两组ACA-IgM、ACA-IgG、A-β_(2)GPI-IgM、A-β_(2)GPI-IgG阳性率比较,差异均无统计学意义(P>0.05)。结论抗心磷脂抗体、抗β_(2)糖蛋白Ⅰ抗体与不明原因胚胎反复种植失败无明显相关性。

血清半胱氨酸蛋白酶抑制剂C检验在诊断高血压患者早期肾损伤中的价值探析

目的分析Cys C(血清半胱氨酸蛋白酶抑制剂C)检验在诊断高血压患者早期肾损伤中的价值。方法选取我院收治的159例原发性高血压疑似合并早期肾损伤患者为研究对象,根据99mTc-DTPA(99mTc-二乙三胺五醋酸)清除率为标准,将159例原发性高血压患者分为肾损伤组与对照组,肾损伤组63例,对照组96例,均进行Cys C检测,分析Cys C在原发性高血压早期肾损伤中的诊断价值。结果肾损伤组患者血清Cys C值显著高于对照组(P<0.05),有统计学意义;且早期肾损伤组血清Cys C>1.26 mg/L发生率显著高于对照组,有统计学意义(P<0.05)。结论血清半胱氨酸蛋白酶抑制剂C检验在高血压患者早期肾损伤中的诊断价值显著,值得推广。

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).     

低密度脂蛋白在2型糖尿病骨质疏松中的作用研究进展

2型糖尿病及骨质疏松已成为我国最主要的慢性代谢性疾病。2型糖尿病常伴有血脂紊乱，常表现为低密度脂蛋白升高，而越来越多的研究表明血脂通过不同的方式影响骨代谢，其机制可能是通过抑制骨髓间充质干细胞成骨分化，通过RANK/RNAKL/OPG信号通路及炎症反应调节破骨细胞等方式调节骨代谢。

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.
