目的:探讨眼附属器淋巴瘤(OAL)的发病情况、临床表现及病理分型,以提高临床诊治水平。

方法:选取2005-08/2013-07在华西医院眼科确诊的OAL患者147例,收集患者的一般情况、临床表现、临床检查(影像学、病理学)结果、治疗及预后情况等临床资料进行回顾性研究。

结果:本研究纳入OAL患者147例,其中男91例(61.9%),女56例(38.1%); 年龄3.5~87岁; 病程20d~10a; 发病部位以眼眶最多见(106/147); 最常见的临床表现为眼部包块、眼睑肿胀、眼球突出; 病理分型以黏膜相关淋巴组织边缘区B细胞淋巴瘤最多见(112/147),且其预后最好,而弥漫大B细胞淋巴瘤、结外NK/T细胞淋巴瘤,鼻型预后最差。

结论:OAL病理类型复杂,发病部位和临床表现多样,免疫组织化学染色是OAL鉴别诊断的重要依据,其预后与病理类型密切相关。  相似文献

BackgroundWe investigated the relationships between serum choline and betaine levels with metabolic syndrome-related indices in the general population of Newfoundland.Methods1081 adults were selected from the CODING study. Serum choline and betaine levels were measured. Major confounding factors were controlled in all analyses.ResultsPartial correlation and linear regression analysis showed that serum choline levels were positively associated with systolic blood pressure (r: 0.124), serum TG levels (r: 0.132) and negatively correlated with serum glucose levels (r: −0.121) in males (p < 0.01 for all). In females, serum choline levels were positively correlated with serum TG, TC and HDL levels (r: 0.104 to 0.148, p < 0.05 for all). Serum betaine levels were negatively associated with serum TG, TC, LDL and insulin levels, and with atherogenic index and HOMA-IR index in males (r: −0.081 to −0.179, p < 0.05 for all). In females, serum betaine levels were negatively associated with serum TG, hsCRP and insulin levels, and with HOMA-IR index (r: −0.092 to −0.213, p < 0.05 for all). Moreover, subjects with serum choline levels in the highest tertile showed highest serum TG levels and systolic blood pressure in males, and highest serum lipids levels in females. Subjects with the highest serum betaine levels had the lowest serum lipids levels, atherogenic index, IR severity in males, and the lowest serum TG and hsCRP levels, and IR severity in females.ConclusionLow serum choline and high serum betaine levels are associated with favorable components of metabolic syndrome in general adults.  相似文献

方法:选取2016-09/12间在四川大学华西医院眼科近视手术中心行ICL/TICL植入术的高度近视性屈光不正患者25例43眼,常规检查裸眼视力(uncorrected visual acuity, UCVA)、最佳矫正视力(best corrected visual acuity,BCVA)、屈光度、眼压、角膜内皮细胞计数、对比敏感度和屈光矫正对生活质量的影响问卷(the quality of life impact of refractive correction questionnaire,QIRC)评分,收集术后1d, 1wk,1、3mo随访数据,采用重复测量方差分析、 LSD-t检验和配对样本t检验进行数据处理。

结果:术后UCVA和BCVA较术前提高,且各个时间点差异均有统计学意义(均P<0.01); 术后各个时间点等效球镜较术前降低,差异有统计学意义(均P<0.01),且术后各个时间点两两比较差异无统计学意义(均P>0.05)。术后3mo安全指数为1.38±0.24,有效指数为1.22±0.15。术前和术后各个时间点眼压的比较,差异无统计学意义(F=1.464,P=0.215),术后3mo内皮细胞密度较术前差异无统计学意义(t=-0.544, P=0.586)。术后高频对比敏感度优于术前水平,差异有统计学意义(12.0c/d:F=4.347,P=0.010; 18.0c/d:F=4.539,P=0.005); 低频变化差异无统计学意义(3.0c/d:F=1.094,P=0.354; 6.0c/d:F=1.325,P=0.271)。术后QIRC问卷评分与术前比较差异无统计学意义(F=2.669,P=0.094)。

结论:ICL V4c植入术是一种安全、有效地矫正高度近视性屈光不正的手术方式。  相似文献

AIM: To explore the pathogenesis of asymmetric primary open angle glaucoma (POAG) in both eyes by comparing the intraocular pressure (IOP) of patients who sleep in different positions and to investigate the relationship between IOP variations and sleep positions. METHODS: One hundred and thirty-one patients with asymmetric POAG and forty-six healthy volunteers were enrolled. All participants completed a questionnaire that provided information about their sleep laterality. The cup disc ratio (C/D) and visual field defect established binocular asymmetry. The IOP of both eyes was measured using iCare parameters after the patients were asked to change body position. The “worse” and “better” eyes were identified according to the diagnosis, whereas the “dependent” and “independent” eyes were defined according to the lateral position. RESULTS: No significant difference in sleep laterality was observed between healthy people and patients with POAG (F=3.195, P=0.362). Among the enrolled patients, the IOP of the dependent eye was always greater than that of the independent eye in the lateral position (P<0.05). In the patients with binocular asymmetric POAG, the questionnaire clearly showed that 85.7% of left side preferences were found their left eyes to be the worse eyes and the right eyes of 71.4% patients with a right side preference were the more serious. When the asymmetric C/D ratio was greater than or equal to 0.2, the worse eye of patients with POAG and a preferred sleeping position was the dependent eye (χ2=16.762, P=0.001). CONCLUSION: A higher IOP was measured in the dependent eye in the lateral position. The long-term tendency to choose a lateral sleeping position might lead the dependent eye to manifest more severe symptoms than the independent eye. Thus, the lateral sleeping position might be one cause of asymmetric POAG.  相似文献

BackgroundThe overexpression of CXCR4, C-Met and VEGF-C present widely in breast tumors, they may be markers of resistance to treatment. However, the studies are still controversial. Thus, this meta-analysis aims to research the relationship between the overexpression of CXCR4, C-Met, VEGF-C and clinical prognosis among breast cancer patients.MethodsPubMed and EMBASE databases were searched for eligible literature. The outcomes of interest were progression-free survival (PFS), relapse-free survival (RFS) and overall survival (OS). All tests of statistical significance were two sided.ResultsA total of 7830 patients from 28 eligible studies were assessed. The overexpression of the CXCR4 and C-Met both implied significantly worse PFS compared with normal expression [HR = 2.56, 95% CI = 1.34–4.91, P = 0.005; and HR = 1.63 95% CI = 1.20–2.22, P = 0.002]. Meanwhile, if patients had high expression of CXCR4, they would have worse OS [HR = 2.56 95% CI = 1.52–4.31, P = 0.000]. However, the overexpression of C-Met did not relate to OS for breast cancer patients [HR = 1.16, 95% CI = 0.69–1.95, P = 0.570]. Meanwhile, no statistically significant different was observed with respect to PFS and OS between VEGF-C overexpression and normal expression [HR = 0.99, 95% CI = 0.64–1.52, P = 0.968; and HR = 0.76, 95% CI = 0.43–1.33, P = 0.333].ConclusionsOur meta-analysis showed that CXCR4 and C-Met were efficient prognostic factors for breast cancer. Nevertheless, highly expressing VEGF-C was not related to progression-free survival and overall survival. Due to the small samples and insufficient date, further studies should be conducted to clarify the association between the overexpression of CXCR4 or C-Met or VEGF-C and the prognosis about breast cancer patients.  相似文献

目的:比较强脉冲光(IPL)联合睑板腺按摩和单纯睑板腺按摩对睑板腺功能障碍(MGD)的短期疗效差异。方法:选取2019-10/2020-01在四川大学华西医院眼科就诊的MGD患者共40例80眼,随机分为试验组和对照组,两组均接受3次治疗,每次治疗中试验组双眼接受IPL联合睑板腺按摩,对照组双眼接受单纯睑板腺按摩,治疗时间间隔为2wk,整个试验期间两组均双眼应用玻璃酸钠每天4次,在每次治疗之前及最后一次治疗2wk后进行指标评估,从而评估IPL联合睑板腺按摩的短期疗效。结果:治疗后两组OSDI、SPEED评分均降低(P<0.05),两组间无差异(P>0.05)。两组睑板腺功能评估(MGE)、泪膜脂质层厚度(LLT)均升高,对照组升高较试验组慢,且第二、三次治疗后试验组MGE高于对照组(P<0.05)。两组泪膜破裂时间(BUT)均升高。两组角膜染色均下降,对照组下降较试验组慢,但两组间无差异(P>0.05)。两组视觉质量持续改善,但对照组改善较试验组慢,两组间无差异(P>0.05)。两组泪液分泌、不完全眨眼比例、睑板腺缺失率无明显变化(P>0.05)。所有受试者未出现皮肤、视力损害、眼压改变、眼前节炎症等并发症。结论:IPL联合睑板腺按摩与单纯睑板腺按摩对MGD均安全有效。IPL见效更快,效果可能有累积效应,在达到一定治疗次数后疗效更好。  相似文献

婴儿眼球震颤综合征(infantile nystagmus syndrome,INS)是一种先天性病理性眼球震颤,以双眼非自主性的共轭摆动和反向视动性眼球震颤为特征表现。INS患者可合并弱视、斜视及斜颈等,常有不同程度的视功能障碍。该病病因尚不明确,且无法完全治愈,应尽早对INS进行检查和适当干预。基于国内外对INS的研究成果,本文首先总结了INS目前所知的病因及发生机制; 其次,介绍了INS近年提出的检查方法与治疗方案,总结了相关临床实践中存在的问题,并在此基础上,对未来可能的研究方向给出了建议,旨在为临床应用及未来研究方向提供参考。  相似文献

目的:在民航招飞学员中研究屈光度预测远视力的模型,并初步探讨中国民航招飞远视力范围标准。
  方法:收集1219名中国民航飞行学院2006/2013年招飞体检学生的远视力和屈光度;以屈光度为自变量,远视力为因变量拟合指数回归曲线模型;依据模型计算不同屈光度对应的远视力预测值及其95%预测区间,并计算误差率,误差率=[(远视力预测值-实际均值)/实际均值]×100%。
  结果:以屈光度( x)预测远视力( y)的曲线模型为:y=0.55e0.41x+e (R2=0.968),远视力预测误差率平均为3.64%;屈光度[0.00,-3.00] D范围的远视力预测区间[0.14,0.55]与现行标准(0.3≤远视力<0.7)有交叉。结论:该模型拟合效果良好,可根据屈光度预测合理的远视力范围。建议中国民航招飞时保持屈光度标准[0.00,-3.00]D不变,将远视力标准降至0.1。  相似文献
