妊娠期细菌性阴道病的研究进展

细菌性阴道病(BV)属于阴道分泌物紊乱综合征,是由较高浓度的特征性需氧菌和厌氧菌替代了正常的乳杆菌引起的。妊娠期细菌性阴道病发病率高,可引起早产和足月前胎膜早破等不良妊娠结局。目前国际上对于筛查和治疗妊娠期BV仍存在很多争议,本文对BV的阴道内环境菌群及微生态平衡与失衡、临床特点、实验室诊断以及治疗进行综述,以对BV有更深的认识,减少BV诱发的盆腔炎、子宫内膜炎、不孕不育或流产、早产或出生低体重儿、产后感染等妇产科疾病,保障妇女身体健康以及优生优育具有一定意义。

长链非编码RNA在急性髓系白血病中的研究进展

长链非编码RNA(lnc RNA)并非“转录噪音”，其可在转录前、转录后及表观遗传水平调节基因表达从而参与疾病的发生、发展。大量研究表明，lnc RNA的异常表达在急性髓系白血病的发生、发展以及耐药等方面起着重要作用。Lnc RNA可通过作用于靶基因并调控相关信号通路参与急性髓系白血病的发生、发展以及耐药，检测其表达量具有一定的预后价值。因此，本文就lnc RNA在急性髓系白血病中的研究进展作一简要论述，希望能为临床诊断和靶向治疗提供思路。     

正常角膜及圆锥角膜的生物力学特性比较研究

Objective To compare the corneal hysteresis (CH) and corneal resistance factor (CRF) measured with the Ocular Response Analyzer (ORA) in normal and keratoconic eyes. Methods It was a case-control study. Random selected 96 normal eyes and 46 keratoconic eyes in the same period were included in this study. Normal eyes were divided into 2 groups: high corneal astigmatism (≥3.00 D) and low-to-moderate corneal astigmatism (<3.00 D). Keratoconic eyes were also divided into 3 groups based on Amsler-Krumeich classification: mild (stage Ⅰ), moderate (stage Ⅱ) and severe (stage Ⅲ/Ⅳ). CH and CRF were compared between groups and the areas under ROC curves of the CH and CRF were calculated. Results The mean CH and CRF were (7.1±1.6) mm Hg and (6.3±1.5) mm Hg in keratoconic eyes compared with (10.1±1.3) mm Hg and (10.5±1.6) mm Hg in normal eyes. The difference were statistically significant(t=-11.813, -14.943 ;P<0.001). In normal eyes, there was no difference of CH or CRF between the high corneal astigmatism and low-to- moderate corneal astigmatism (t=0.373,0.095; P>0.05). In keratoconic eyes, there was a significant negative correlation between CH and the keratoconus grade (r=-0.627, P<0.001) and the same relationship was found between CRF and the keratoconus grade (r=-0.587, P<0.001). In multiple linear regression analysis, CH was correlated with central corneal thickness (CCT) and corneal curvature (r=0.320, -0.375;P<0.05) and CRF was correlated with corneal curvature in keratoconic eyes (r=-0.441 ,P<0.01), while they were only correlated with CCT in normal eyes (r=0.367,0.459;P<0.001). The areas under ROC curves of the CH and CRF were 0.9282 and 0.9731 (Z=20.462,38.305 ;P<0.0001), the difference between them was significant (Z =7.134,P=0.008). Conclusions The CH and CRF were significantly lower in keratoconic eyes than in normal eyes, especially on CRF. The long-term follow-up of CH and CRF may provide information for evaluation of progression of keratoconus. They may be included as indicators for detecting keratoconus.     

载脂蛋白H基因多态性与高血压肾损害及肾实质性高血压

目的探讨载脂蛋白H(ApoH)基因多态性与高血压肾损害及肾实质性高血压的关系.方法采用PCR-单链构象多态技术(PCR-SSCP),对黑龙江地区96例高血压-肾功能正常患者(EH-NRF)、92例高血压-肾功能衰竭患者(EH-CRF)和104例肾实质性高血压-肾功能正常患者(RH-NRF)、112例肾实质性高血压-肾功能衰竭患者(RH-CRF)及100例健康对照者(NC)的ApoH基因多态性进行检测.结果黑龙江地区汉族人ApoH基因3号外显子存在G341A(Ser88Asn)多态,EH-NRF及EH-CRF组G341A(Ser88Asn)多态A等位基因频率高于 RH-NRF、RH-CRF及NC组(P<0.05,P<0.01);EH-CRF 组A等位基因频率高于EH-NRF组(P<0.05);RH-NRF及RH-CRF组等位基因频率与NC组差异无显著意义.结论 G341A(Ser88Asn)多态A等位基因可能是黑龙江地区汉族人高血压的遗传危险因素,但不能用ApoH基因多态性来解释肾性高血压,说明高血压并发尿毒症与尿毒症并发高血压存在不同的遗传基础.     

三个候选基因多态性与糖皮质激素性骨质疏松症关联的研究

目的探讨护骨素（OPG）A163G、瘦素受体（LEPR）Gln223Arg和过氧化物酶体增殖物激活受体γ（PPARγ）C161T3个单核苷酸多态性（SNPs）与糖皮质激素性骨质疏松症（GIO）的关系。方法选择哈尔滨医科大学附属第一医院肾内科患者采用限制性片断长度多态性法,在208例健康对照组、168例非GIO组和104例GIO组中分析A163G、Gln223Arg和C161T多态性的基因型分布;应用双能X线骨密度仪（DEXA）测定股骨、腰椎等部位的骨密度。结果在单基因研究中,GIO组患者与健康对照组比较,A163G和C161T基因型和等位基因频率差异有显著意义（P〈0.05）;采用多基因联合分析,OPGGG纯合子中,PPARγTT纯合子GIO患病率显著增高（OR=2.04,95%CI1.26～3.67,P=0.02）。结论OPG A163G和PPAR γC161T多态性可能与GIO的发病相关;在GIO人群中,OPG A163G和PPAR γC161T多态可能有协同作用。
