目的:观察两种手术对青光眼患者的视野和视网膜神经纤维层厚度的影响。方法:收集2015-12/2017-05我院行抗青光眼手术患者69例82眼的临床资料,根据手术方法分为EP组(EXPRESS引流钉植入术)和XQ组(小梁切除术)。于术前和术后1、3mo观察眼压、前房深度(anterior chamber depth,ACD)、前房容量(anterior chamber volume,ACV)、前房角宽度(anterior chamber angle,ACA)、瞳孔直径(pupil diameter,PD)、视力、视野光敏感度平均缺损(mean defect,MD)、视野指数矫正模式标准差(correct pattern standard deviation,CPSD)、周边视野的光敏感度(mean sensitivity,MS)、视网膜神经纤维层厚度(retinal nerve fiber layer thickness,RNFLT),并对比术后并发症情况。结果:EP组住院时间(3.08±0.42d)明显低于XQ组(4.53±1.28d),差异有统计学意义(t=6.124,P0.05)。两组患者术后RNFLT、MD、CPSD均降低,MS升高,差异有统计学意义(P<0.05);与XQ组对比,EP组术后的CPSD明显降低,差异有统计学意义(P <0. 05)。EP组术后并发症总发生率为38%,明显低于XQ组(70%),差异有统计学意义(χ2=8.094,P=0.004)。结论:与小梁切除术对比,EX-PRESS引流钉植入术更有效地减缓视野进展,更有利于患者术后视力的恢复,安全性更高,而其在RNFLT改善程度与小梁切除术效果一致。

基于模糊数学基本思想,将海水入侵程度作为评价对象,选择Cl–、Br–、SO42–、K+、SAR等5项能敏感反映海水入侵过程的水化学指标作为评价指标,通过采用改进层次分析法计算各指标权重和运用模糊数学进行综合评价,构建海水入侵程度综合评价的数学模型。以山东省招远市作为研究区,运用评价模型对该地区海水入侵程度进行评判,评价结果较单一指标评价法更加合理准确,具有较好的实用性,可为当地海水入侵防控提供科学依据。研究表明,该模型是海水入侵程度评价的一种简易高效、科学合理的方法,可推广应用。

The origin of the biota of Hainan Island, China, remains a fundamental scientific problem. Comparative studies on the biota, geological tectonics, and paleomagnetism proposed that during the Eocene, Hainan Island connected Vietnam and Guangxi, and then moved to the southeast to reach its present location. This review mainly discusses its biota origin from molecular phylogeny and palaeobotanical research. The formation and evolution of the biological groups of Hainan Island were identified via research on their genomes, phylogeny, and molecular biogeography. This research showed that the genera and species that appeared and diverged early in their evolution(i.e., before the Miocene) can be explained by the land connection between Hainan Island, Vietnam, and Guangxi during the Eocene-Oligocene. According to Southeast Asian tectonic theory, in the Middle Miocene(at about 15 million years ago), Hainan Island had moved to its present position. The population and genetic divergence of species with late divergence times(after 15 Ma) can be reasonably explained by the close proximity(or land connection) between Hainan Island and the Leizhou Peninsula, enabling genetic communication between Hainan Island and the Chinese mainland, but have exceptional cases. Conclusions have been obtained through palaeobotanical studies, showing that in the Eocene-Oligocene period, southwest China and Hainan Island had subtropical vegetation and flora. However, the fossil group in southeast China(in Maoming, near present-day Hainan Island) in the Late Eocene indicated a tropical rainforest vegetation and flora. This suggests that in the Paleogene, Hainan Island may have been located near or on the southwest border of Guangxi and northern Vietnam, rather than in its present location. The floristic division of the flora of Hainan Island basically presents a northeast-southwest inclined distribution pattern. This pattern can be explained by the counterclockwise rotation of Hainan Island during i

对济南泉域岩溶地下水系统水质进行了系统的采样分析。结果表明,泉域岩溶水已普遍受有机物污染,有机污染物检出率高达93%。检出有机物多于5项的样品多分布于大中型企业附近。在所有检出的有机物中,有机氯农药类、卤代烃类检出率最高,分别达到60%、57.8%。尽管岩溶水有机污染较普遍,但有机物含量较低,仅局部地段存在有机物超标现象。泉域岩溶水有机污染特征受控于工业企业分布及地下水流场,在济南侵入岩体南缘附近形成了近长方形的岩溶水有机污染区,面积达156 km2。污染区南部地带是济南市工业集中区,灰岩浅埋,防污性能差,另外由于地下水径流方向与侵入岩体南缘线近垂直,进入灰岩含水层的有机污染物随地下水径流向北运移,造成埋藏于火成岩体之下的埋藏型岩溶水也受到污染。
