简介：目的：探讨糖尿病视网膜病变（diabeticretinopathy，DR）患者血清中生长停滞特异基因6（growtharrestspecificgene6，Gas6）、基质细胞衍生因子（stromalcell-derivedfactor-1，SDF-1）和SDF-1β表达的变化及临床意义。方法：DR患者113例分为增殖性组（n=45）和非增殖性组（n=68），同期选取未合并DR糖尿病患者作为糖尿病组（49例）和健康者42例，检测血糖、血脂和超敏C-反应蛋白（highlysensitiveC-reactiveprotein，hs-CRP）指标，利用实时荧光定量PCR技术检测血清中Gas6、SDF-1α和SDF-1β基因表达。结果：糖尿病组、非增殖性组和增殖性组患者稳态模型的胰岛素抵抗指数（homeostasismodelassessmentforinsulinresistance，HOMA-IR）、甘油三酯（triglycerides，TG）和hs-CRP均逐渐升高，差异均有统计学意义（F=39.672、81.625、99.872，均P〈0.05），增殖性组和非增殖性组患者低密度脂蛋白（low-densitylipoprotein，LDL-C）均高于糖尿病组和健康者，而高密度脂蛋白（highdensitylipoprotein，HDL-C）均低于糖尿病组和健康者，差异均有统计学意义（F=51.974、43.824，均P〈0.05）；增殖性组、非增殖性组和糖尿病组患者血清Gas6mRNA表达量均高于健康者，增殖性组患者血清SDF-1αmRNA表达量均高于非增殖性组、糖尿病组和健康者，增殖性组和非增殖性组患者血清SDF-1βmRNA表达量均高于糖尿病组和健康者，且增殖性组患者高于非增殖组，差异均有统计学意义（F=15.381、21.589、38.942，P〈0.05）；Pearson相关分析显示，DR患者血清Gas6mRNA表达量与TG、总胆固醇（totalcholesterol，TC）和LDL-C呈正相关（r=0.228、0.241、0.209，均P〈0.05），血清SDF-1αmRNA和SDF-1βmRNA表达量均与hs-CRP呈正相关（r=0.297、0.325，P〈0.05）。结论：DR患者血清中Gas6、SDF-1α和SDF-1β基因表达水平升高，可能与患者血脂代谢异常及炎性反应有关。

简介：三、盲和低视力的原因阜阳市颖州区盲和低视力的原因中，白内障仍高居首位，占59．06％，其次为弱视，7．09％，第三位为青光眼，5．12％。（见表5）

简介：目的方法结果结论对安徽省两地人群盲和低视力及眼病的流行病学情况进行抽样调查。选择阜阳市颍州区和宣城市绩溪县,采用随机整体抽样方法,对所属居民进行眼部及其他情况的调查。两地的受检人数和受检率分别为3336人（91.40%）和3602人（92.10%）,达到抽样调查要求;两地双眼盲、单眼盲、双眼低视力和单眼低视力的患病率分别为1.05%和0.69%、1.71%和1.25%、1.02%和0.97%、0.87%和0.89%;两地盲和低视力的主要原因分别为：白内障、弱视、青光眼和白内障、眼球萎缩/缺如、青光眼;两地主要眼病都为：屈光不正、白内障、翼状胬肉和沙眼;两地的白内障手术率分别为600和278。据不完全资料估计我省盲和低视力的患病率远高于全国平均水平,盲和低视力的高发人群为50岁以上老年人,女性,孤寡,文盲,低收入者,白内障仍是最主要致盲原因,屈光不正/弱视已日益成为影响人民特别是青少年视力的最主要因素,广泛宣传正确用眼方式,推广青少年正确验光配镜方法,提高相关人员验光配镜水平对于有效降低弱视致残率至关重要。

简介：目的探讨微创玻璃体切割联合白内障超声乳化术治疗增生性糖尿病视网膜病变（PDR）的临床疗效。方法回顾性分析PDR患者16例（16只眼）均行微创玻璃体切割联合白内障超声乳化术，术中行全视网膜光凝。其中3只眼行硅油填充，6只眼行气体（C3F8）填充，术后3—6个月行硅油取出术，术后随访6个月。结果16只眼随访12个月，视网膜复位良好，12只眼矫正视力显著提高，4只眼因视神经萎缩视力无提高，3只眼后囊增生明显。结论微创玻璃体切割联合白内障超声乳化术是治疗PDR有效的方法，具有良好的临床前景。

简介：糖尿病视网膜病变（DR）是作为一种常见的糖尿病并发症，对其发病机制的研究一直是关注的焦点。经典的糖尿病视网膜病变的发病机制假说集中与多元醇通路的异常、蛋白质非酶糖基化产物的堆积、蛋白激酶C及氨基己糖途径有关。聚腺苷二磷酸核糖聚合酶（PARP）作为统一机制中的一个关键分子，与DR发病机制及其防治密不可分，对其进行适当干预，可成为DR治疗的重要方法之一。

简介：目的探讨玻璃体腔注射雷珠单抗辅助23G玻璃体切割治疗增殖期糖尿病视网膜病变的优质护理。方法通过对28例28眼采用玻璃体腔注射雷珠单抗辅助玻璃体切割治疗糖尿病患者并发视网膜增殖期病变存在的主要护理问题，针对患者治疗各阶段，责任护士提供全程、连续、系统的优质护理服务，加强护患沟通，提高护理质量，缩短手术时间，减少并发症的发生。结果24眼一次性手术复位成功（85．7％）术后三个月取出硅油，其中有4例伴有晶状体混浊的同时行晶状体超声乳化联合人工晶体植入术；4例硅油填充下仍然存在下方局限性视网膜增殖，术后三个月取出硅油再次切割增殖膜然后注入C3F8气体填充，随访至气体完全吸收，视网膜复位。结论对玻璃体腔注射雷珠单抗辅助23G玻璃体切割治疗增殖期糖尿病视网膜病变的患者提供优质护理，可缩短手术时间，减少并发症的发生，提高病人及家属的满意度，提升患者的康复效果，是手术取得成功的关键因素。

简介：目的:通过测定糖尿病性白内障患者血清中糖代谢指标、胰岛素抵抗与房水和血清中炎症因子的水平,探讨其相关性。方法:随机选取我院2017-02/2018-01糖尿病性白内障患者69例(观察组)和白内障患者65例(对照组),检测两组患者血清中糖化血红蛋白(HbA1c)、空腹血糖(FPG)、空腹胰岛素(FINS)的水平,计算胰岛素抵抗指数(HOMA-IR);同时检测房水和血清中的胰岛素样生长因子-1(IGF-1)、白细胞介素-6(IL-6)含量,对HbA1c、HOMA-IR与房水和血清中IGF-1、IL-6含量进行相关性分析。结果:对照组血清中的FPG、HbA1c、HOMA-IR,以及房水和血清中IGF-1、IL-6含量显著低于观察组,差异有统计学意义(均P<0.05)。HbA1c与房水及血清中的IGF-1和IL-6均呈正相关(P<0.05)。HOMA-IR与房水及血清中的IGF-1和IL-6均呈正相关(P<0.05)。结论:糖尿病性白内障患者HbA1c、HOMA-IR与房水及血清中的IGF-1、IL-6含量具有相关性,通过对上述指标的测定可以辅助判断病情。

简介：目的了解上海市普陀区4-7岁儿童阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的患病率及相关危险因素,探讨问卷调查在筛选疑似病例中的价值。方法以班级为单位采取整群抽样的方法从上海市普陀区幼儿园及小学一年级中抽取4-7岁学生6000例,由学生家长填写问卷,再从中随机抽取无打鼾或轻微打鼾者10例,有频繁打鼾症状的儿童42例,行多导睡眠监测。结果实际调查人数5040（应答率为84.0%）,有效问卷4045份（有效率为80.23%）,按睡眠呼吸暂停低通气指数（AHI）≥5次/h、最低血氧饱和度（LSaO2）≤0.94为标准,根据多导睡眠监测结果,估算上海市4-7岁儿童OSAHS的患病率为3.91%。AHI与腺样体肥大相关性较强（偏相关系数为0.373）;将问卷中打鼾、憋气、反复翻身、夜尿发生率等选项分配一个0-4分的数值,调查问卷得分与AHI呈正相关（r=0.518）。问卷中打鼾、张口呼吸选项的敏感度较高（95%、87%）,特异性一般（67%、79%）;憋气、憋醒选项敏感度一般（66%、29%）,特异度较高（93%、100%）;夜尿及反复翻身选项无统计学意义（P〉0.05）。结论上海市普陀区4-7岁儿童OSAHS的患病率估计为3.91%,腺样体肥大为患病主要原因;设计合理的调查问卷可用于初步筛选儿童OSAHS疑似病例,对早期诊断和治疗具有重要参考价值。
