| 1 | 中国有壳变形虫Argynnia(Vucetich,1974)属的修订及若干环境重建问题探讨显示文摘有壳变形虫是一类具外壳的陆相淡水根足纲(Rhizopoda)原生动物,广泛栖息于湖泊、泥炭、沼泽、土壤等各种淡水潮湿环境,由于其壳体具有很好的抗腐蚀性而在沉积物中保存下来,近年来广泛应用于泥炭和湖泊湿地的古环境重建研究中。大部分有壳变形虫是世界广泛分布的,但是也有一些种类具有一定的地带性分布格局。形态学和分子生物学的研究均已表明阿吉尼亚虫属(Argynnia Vucetich,1974)与梨壳虫属(Nebela Leidy,1874)有较大差别,而我国传统的有壳变形虫分类系统仍将它们统一划为梨壳虫属(Nebela)。本文在对神农架大九湖泥炭湿地有壳变形虫标本形态学观察的基础上,结合前人研究资料,将阿吉尼亚虫属(Argynnia)从梨壳虫属(Nebela)中分离出来,修正了我国传统的分类系统,并讨论了其生物地理学意义,目前在我国发现该属的2个种,即具尾阿吉尼亚虫Argynnia caudata(Leidy,1876)和齿口阿吉尼亚虫Argynnia dentistoma(Penard,1890)。本文还探讨了因有壳变形虫分类标准的差异可能引起的生态学转换函数和古环境重建问题。 | 秦养民 张文静 李鸿凯 Edward A.

| 2 | Dependence of dynamic contour and Goldmann applanation tonometries on peripheral corneal thickness显示文摘AIM:To determine the effects of peripheral corneal thickness(PCT) on dynamic contour tonometry(DCT) and Goldmann applanation tonometry(GAT).METHODS:A cross-sectional study.We created a software which calculates the corneal contour(CC) as a function of the radius from the corneal apex to each pixel of the contour.The software generates a central circumference with a radius of 1 mm and the remainder of the cornea is segmented in 5 rings concentric with corneal apex being its diameter not constant around the corneal circumference as a consequence of the irregular CC but keeping constant the diameter of each ring in each direction of the contour.PCT was determined as the mean thickness of the most eccentric ring.Locally weighted scatterplot smoothing(LOWESS) regression was used to determine the pattern of the relationship between PCT and both DCT and GAT respectively.Thereafter,two multivariable linear regression models were constructed.In each of them,the dependant variable was intraocular pressure(IOP) as determined using GAT and DCT respectively.In both of the models the predictive variable was PCT though LOWESS regression pattern was used to model the relationship between the dependant variables and the predictor one.Age and sex were also introduced control variables along with their first-degree interactions with PCT.Main outcome measures include amount of IOP variation explained through regression models(R2) and regression coefficients(B).RESULTS:Subjects included 109 eyes of 109 healthy individuals.LOWESS regression suggested that a 2 nd-degree polynomial would be suitable to model the relationship between both DCT and GAT with PCT.Hence PCT was introduced in both models as a linear and quadratic term.Neither age nor sex nor interactions were statistically significant in both models.For GAT model,R2 was 17.14%(F=9.02;P=0.0002),PCT linear term B was-1.163(95% CI:-1.163,-0.617).PCT quadratic term B was 0.00081(95% CI:0.00043,0.00118).For DCT model R2 was 14.28%(F=9.29;P=0.0002),PCT linear term B was-0.712(95% CI:-1.052,-0.372),PCT quadratic term was B=0.0005(95% CI:0.0003,0.0007).CONCLUSION:DCT and GAT measurements are conditioned by PCT though this effect,rather than linear,follows a 2^(nd)-degree polynomial pattern. | Federico Saenz-Frances Claudia Sanz-Pozo Lara Borrego-Sanz Luis Ja?ez Laura MoralesFernandez Jose Maria Martinez-de-la-Casa Julian Garcia-Sanchez Julian Garcia-Feijoo Enrique Santos-Bueso | 2017 | International Journal of Ophthalmology(English edition)2017，10，10： | 1 |

| 6 | Anatomical characterization of central, apical and minimal corneal thickness显示文摘·AIM: To anatomically locate the points of minimum corneal thickness and central corneal thickness(pupil center) in relation to the corneal apex.·METHODS: Observational, cross-sectional study, 299 healthy volunteers. Thickness at the corneal apex(AT),minimum corneal thickness(MT) and corneal thickness at the pupil center(PT) were determined using the pentacam. Distances from the corneal apex to MT(MD)and PT(PD) were calculated and their quadrant position(taking the corneal apex as the reference) determined:point of minimum thickness(MC) and point of central thickness(PC) depending on the quadrant position. Two multivariate linear regression models were constructed to examine the influence of age, gender, power of the flattest and steepest corneal axes, position of the flattest axis, corneal volume(determined using the Pentacam)and PT on MD and PD. The effects of these variables on MC and PC were also determined in two multinomial regression models.·RESULTS: MT was located at a mean distance of 0.909 mm from the apex(79.4% in the inferior-temporal quadrant). PT was located at a mean distance of 0.156 mm from the apex. The linear regression model for MD indicated it was significantly influenced by corneal volume(B =-0.024; 95% CI:-0.043 to-0.004). No significant relations were identified in the linear regression model for PD or the multinomial logisticregressions for MC and PC.·CONCLUSION: MT was typically located at the inferiortemporal quadrant of the cornea and its distance to the corneal apex tended to decrease with the increment of corneal volume. | Federico Saenz-Frances Martha Cecilia Bermúdez-Vallecilla Lara Borrego-Sanz Luis Jaez J osé Marìa Martinez-de-la-Casa Laura Morales-Fernandez Enrique Santos-Bueso Julián Garcia-Sanchez Julián Garcia-Feijoo | 2014 | International Journal of Ophthalmology(English edition)2014，7，4： | 0 |

| 8 | Correlations between corneal and optic nerve head variables in healthy subjects and patients with primary open angle glaucoma显示文摘AIM: To correlate corneal variables(determined using the Pentacam) with optic nerve head(ONH) variables determined using the Heidelberg retina tomograph(HRT)in healthy subjects and patients diagnosed with primary open angle glaucoma(POAG).·METHODS: Measurements were made in 75 healthy eyes and 73 eyes with POAG and correlations examined through Pearson correlation coefficients between the two sets of variables in the two subject groups. The corneal variables determined were corneal volume(CVol), central corneal thickness(CCT), overall corneal thickness(Ov CT), the mean thickness of a circular zone centered at the corneal apex of 1 mm radius(zone I) and the mean thickness of several concentric rings, also centered at the apex until the limbus, each of 1 mm width(zones II to VI respectively). The ONH variables were determined using the HRT.· RESULTS: The following pairs of variables were correlated in the control group : CCT- disc area( DAr)(-0.48; P <0.0001), Zone I-DAr(-0.503; P <0.0001) and Zone II-DAr(-0.443; P <0.0001); and in the POAG group:CCT-cup-to-disc area ratio(CDRa)(-0.402; P <0.0001),Zone I-CDRa(-0.418; P <0.0001), Zone II-CDRa(-0.405;P =0.006), Zone I-cup shape measure(CSM)(-0.415; P =0.002), Zone II-CSM(-0.405; P =0.001), Zone IV-height variation contour(HVC)(0.378; P =0.002); Zone V-HVC(0.388, P <0.0001).· CONCLUSION: In the healthy subjects, significant negative correlation was detected between central andparacentral corneal thickness and optic disc area. In contrast, the POAG patients showed significant negative correlation between central and paracentral corneal thickness and the cup-disc ratio and CSM, and positive correlation between peripheral corneal thickness and HVC. | Federico Saenz-Frances Luis Janez Lara Borrego-Sanz Clara Berrozpe-Villabona Jose Maria Martinez-de-la-Casa Laura Morales-Fernandez Julian Garcia-Sanchez Enrique Santos-Bueso Julian Garcia-Feijoo | 2015 | International Journal of Ophthalmology(English edition)2015，8，6： | 0 |
