儿童弱视715眼治疗效果的临床分析

目的：探讨儿童弱视临床特点和综合治疗效果。

方法：选取2015-07/2017-07我院确诊收治的弱视儿童393例715眼,建立弱视治疗档案,给予弱视综合疗法治疗,观察其治疗效果,并对其年龄、弱视类型、弱视程度、弱视注视性质和治疗依从性等影响疗效的临床特点进行分析。

结果：患儿393例715眼中,基本治愈者520眼(72.7%),进步者117眼(16.4%),无效者 78眼(10.9%),总有效率为89.1%。年龄、弱视类型、弱视程度、注视性质、治疗依从性等临床特点影响弱视治疗效果。

结论：儿童弱视的总体治疗效果较好。与患儿年龄、弱视类型、弱视程度、弱视注视性质和治疗依从性等临床特点关系密切。年龄偏大,弱视类型为屈光参差性弱视、斜视性弱视,弱视程度重、旁中心注视及依从性差的患儿治疗效果差。     

A pilot study on vitrectomy combined with scleral shortening for eyes with myopic macular retinoschisis——2y follow-up results

AIM:To evaluate the effect of vitrectomy combined with scleral shortening for eyes with myopic macular retinoschisis.METHODS:Thirty-seven patients with myopic macular retinoschisis who underwent pars plana vitrectomy(PPV)combined with scleral shortening were reviewed.Axial length(AL),the height of macular retinoschisis,the height of retinal detachment if existed,the diameter of macular hole if existed and best corrected visual acuity(BCVA)were obtained.The preoperative and postoperative parameters were compared.RESULTS:At postoperative 24 mo,the mean AL and height of macular retinoschisis were reduced significantly by 0.79 mm and 256.51μm(t=8.064,P<0.0001;Z=-5.086,P<0.0001)respectively.In addition,the mean height of retinal detachment and diameter of macular hole were also reduced significantly by 365.38μm and 183.68μm(Z=-4.457,P=0.000008;Z=-2.983,P=0.003)respectively.Meanwhile,the postoperative BCVA was improved markedly(Z=-2.126,P=0.033).CONCLUSION:Vitrectomy combined with scleral shortening is an effective surgical method for eyes with myopic macular retinoschisis,whether or not macular hole and retinal detachment are present.     

复杂高陡构造零偏VSP空变倾角时差校正及其处理技术

英买9井曾在白垩系巴西改组获得高产, 但该井周边部署的井油气显示并不理想。在储层和盖层均发育良好的英买9井区内, 断层对英买9井区内的油气富集具有十分重要的影响。为了研究英买9井区断层对油气聚集的控制作用, 利用英买9井区现有资料, 对泥岩涂抹因子进行了计算, 认为F6断层封闭性最好, F1断层其次。通过计算泥岩断层泥比确定有利断层的封烃高度, 再结合相邻区块已开发井位的烃柱高度, 优化计算英买9井区有利断层的封烃高度, 其中F6断层封烃高度可达19.09m, F1断层封烃高度为14.13m。研究结果对该区下一步井位部署具有一定的指导作用。     

基于视觉-前庭感知一致性的运动模拟可信度评价方法

目的提出以运动感知一致性作为运动模拟的可信度评价标准。方法以客观运动模拟测试(objective motion cueing test,OMCT)为基础,引入了视觉-前庭感知一致性理论,并以人的运动感知一致区为期望边界,从而修正运动模拟可信度评价函数。结果相比Advani-Hosman评价标准,本方法可获得更大的幅值可信度与相位可信度区域,扩大了运动模拟的边界。结论运动感知一致性更适合作为飞行训练运动模拟的可信度评价指标。     

利用PACS实施口腔内科根管治疗质量监控的初步研究

目的 探讨标准化方法监控根管治疗质量的应用效果和存在的问题.方法 5名评价者,采用随机、单盲、对照的方法,对存储于PACS中的根管治疗病例进行评价,使用社会科学统计程序(SPSS ver16.9)分析比较其评价结果.结果 随机抽取病例156例,根据根管治疗中的3个阶段4个方面分别给予评价.对于诊断片和定位片,5名评价者的评价结论无统计学差异；对于根管充填位置和密合程度的评价,存在统计学差异.结论 PACS可以作为临床质量监控的手段；管理者在使用PACS监控根管治疗质量时,应当首先进行标准化培训.     

Serum Concentrations of Antibodies against Outer Membrane Protein P6, Protein D,and T- and B-Cell Combined Antigenic Epitopes of Nontypeable Haemophilus influenzae in Children and Adults of Different Ages

Nontypeable Haemophilus influenzae (NTHi) is one of the most common etiologies of acute otitis media, rhinosinusitis, and pneumonia. Outer membrane proteins (OMPs) are the main focus in new vaccine development against NTHi, as the H. influenzae type b (Hib) vaccine does not cover noncapsulated NTHi. The OMPs P6 and protein D are the most promising candidate antigens for an NTHi vaccine, and low antibody levels against them in serum may be correlated with infection caused by NTHi. In the current study, we measured the antibody titers against P6, protein D, and their T- and B-cell combined peptide epitopes in healthy individuals of different ages. We found that children <1 month old had the lowest antibody levels against NTHi P6, protein D, and their T- and B-cell combined antigenic epitopes. Antibody titers increased at ages 1 to 6 months, peaked at 7 months to 3 years, and remained high at 4 to 6 years. The antibody titers started to decrease after 6 years and were the lowest in the 21- to 30-year group. The geometric mean titers (GMTs) of T- and B-cell combined antigenic epitopes in P6 and protein D were positively correlated with those of the protein antigens. Among 12 peptides tested, P6-61, P6-123, and protein D-167 epitopes were better recognized than others in human serum. These findings might contribute to the development of an effective serotype-independent vaccine for H. influenzae.
