Yanjiahella gen. nov., a distinctive fossil taxon from the Early Cambrian Yanjiahe Biota in Yichang, Hubei Province, is characterized by： 1） an overall body plan composed of a stalk and a calyx （also arms in some species）; 2） a stalk with closely spaced, transverse wrinkles and a medial, longitudinal ridge; and 3） a calyx preserved with three-dimensional radiating striations, as well as a probable madreporite in some specimens. Three species that can be assigned to this genus, which are Y. ancarpa sp. nov., Y. monocarpa sp. nov., and Y. biscarpa sp. nov. Yanjiahella is comparable to certain echinoderm taxa in terms of morphology and some biological structures, which might indicate the early evolution and diversification of ancestral echinoderm lineages from the early Early Cambrian Yangtze Platform. The discovery of putative echinoderms in the Yanjiahe Biota provides significant clues about the origination and evolution of the deuterostome phylum Echinodermata.

The influence of substrate temperature on microstructure, electrical and optical properties of in situ- textured zinc oxide （ZnO） films fabricated by metal organic chemical vapor deposition （MOVCD） had been investigated. Results indicated that the substrate tempera- ture played a very important role on preparation of ZnO thin film. With the raising of temperature, firstly ZnO crystals were perpendicular to the substrate, then they were grown inclining toward the substrate, finally ZnO crystals grown in layers but not regular. Consequently, ZnO film surface morphology changed from smooth to a pyramid structure and then disappeared little by little. Moreover, it was also found in this study that ZnO film was characterized with high crystallinity, low resistivity （2.17 x 10 2） and high transmittance （〉 80%）. These results suggested that ZnO thin film is suitable for front electrode of silicon thin film solar cell.

This paper presents the influence of process parameters, such as argon (Ar) flow rate, sputtering power and substrate temperature on the band gap of Al-doped ZnO film, Al-doped ZnO thin films were fabricated by radio frequency (RF) magnetron sputtering technology and deposited on polyimide and glass substrates. Under different Ar flow rates varied from 30 to 70 sccm, the band gap of thin films were changed from 3.56 to 3.67 eV. As sputtering power ranged from 125 to 200W, the band gap was varied from 3.28 to 3.82 eV; the band gap was between 3.41 and 3.88 eV as substrate temperature increases from 150°C to 300°C. Furthermore, the correlation between carrier concentration and band gap was investigated by HALL. These results demonstrate that the band gap of the Al-doped ZnO thin film can be adjusted by changing the Ar flow rate, sputtering power and substrate temperature, which can improve the performance of semiconductor devices related to Al-doped ZnO thin film.

关键词： Al-doped ZnO thin films band gap carrier concentration argon (Ar) flow rate sputtering power substrate temperature

目的:探讨原发性闭角型青光眼(PACG)患者行青光眼白内障联合手术后3个月的屈光状态以及相关影响因素。方法:前瞻性临床研究。选择2018年12月至2019年9月于吉林大学第二医院眼科中心行小梁切除联合白内障超声乳化摘除及人工晶状体植入术(简称青白联合术)的PACG合并白内障患者51例(51眼)。术前用药后眼压≤21 mmHg(1 mmHg=0.133 kPa)患者作为正常眼压组(24例),>21 mmHg作为高眼压组(27例)。所有患者术前使用AL-scan测量前房深度(ACD)、眼轴长度(AL)、角膜曲率,并通过该仪器内置的SRK-T公式预测术后屈光度。随访至术后3个月行综合验光。根据术后屈光误差(RE)将患者分为近视误差组(RE0.5 D)、无屈光误差组(-0.5 D≤RE≤0.5 D)。正常眼压组与高眼压组患者术后屈光误差分布比较采用卡方检验,近视误差组与远视误差组患者术前生物参数比较采用独立样本t检验,手术前后生物参数比较采用配对样本t检验。结果:正常眼压组患者术后近视误差4例(17%),远视误差3例(12%),无屈光误差17例(71%);高眼压组患者近视误差7例(26%),远视误差16例(59%),无屈光误差4例(15%)。高眼压组患者术后AL缩短程度大于正常眼压组患者,组间差异有统计学意义(t=-4.308,P<0.001)。远视误差组患者术前ACD浅于近视误差组患者,术前AL短于近视误差组患者,组间差异比较均有统计学意义(t=3.226,P=0.03;t=4.993,P<0.001);近视误差组与远视误差组间的角膜曲率差异无统计学意义(t=-1.143,P=0.263)。术后RE与术前ACD、AL均呈负相关(r=-0.32,P=0.023;r=-0.52,P<0.001),与术前角膜曲率无相关性(r=0.15,P=0.101)。结论:相对于术前眼压正常的PACG患者,术前高眼压患者青白联合术后屈光误差发生的比例更高,且大多是远视屈光误差。另外,PACG患者青白联合术后总体上存在术前ACD越浅,AL越短,术后屈光状态越倾向于远视的趋势。

目的:评估存在瞳孔散大的青白联合术后患者行改良瞳孔成形术的临床疗效。方法:回顾性研究。连续性纳入2021年1月至2023年6月就诊于吉林大学第二医院青光眼科青白联合术后瞳孔散大的患者32例(32眼),行改良瞳孔成形术。分别于术前及术后3个月检查最佳矫正视力(BCVA)、瞳孔直径、眼压、周边虹膜前粘连范围、双眼平衡对比度和抑制深度,并采用青光眼生活质量问卷(GQL-15-CHI)和青光眼视觉功能问卷(GVFQ-40)调查评估主观视觉质量。采用配对t检验比较手术前后各项检测指标和问卷评分。结果:共32例(32眼)青白联合术后大瞳孔患者顺利接受改良瞳孔成形术治疗,年龄55~76(64.2±8.5)岁,随访时长3个月。LogMAR的BCVA由术前1.39±0.86,提高至术后的0.92±0.63(t=7.15,P=0.017);瞳孔直径由术前的(6.18±0.30)mm,缩小至术后的(4.02±0.41)mm(t=24.82,P0.05)。术后3个月视觉功能质量问卷总体评分显著低于术前(t=-3.32,P=0.034),其中眩光畏光、视觉运动能力、识别能力、夜视能力的术后3个月评分低于术前(t=-8.31,P=0.002;t=-4.34,P=0.036;t=-4.58,P=0.029;t=-6.93,P=0.005),移动能力和阅读能力手术前后比较差异无统计学意义(P>0.05)。结论:对于存在瞳孔散大变形的青白联合术后患者,改良瞳孔成形术在提高患者术后视力,开放房角,有效控制眼内压的同时,还可明显提升患者的视觉生活质量。
