| 1 | 妊娠性高血压视网膜变化的临床研究(英文)显示文摘目的:研究妊娠性高血压(PIH)患者视网膜变化的患病率,视网膜变化与疾病严重程度的相关性。方法:横断面研究。共收集2014-12/2015-05妊娠性高血压患者100例。所有患者均行眼底检查。单眼或双眼眼底发生变化视为阳性。妊娠性高血压分级为轻度子痫前期(血压>140/90~160/90 mmHg),重度子痫前期(血压>160/90 mmHg)和子痫前期(重度子痫前期和抽搐)。结果:患者平均年龄为23.05(19~34)岁。妊娠期为28~41wk。其中62例初产妇以及38例经产妇。轻度子痫前期,重度子痫前期和子痫前期患者占比分别为62%,26%,12%。8例患者发生视网膜变化。观察得出:高血压性视网膜病变Ⅰ级(1%),Ⅱ级(0%),Ⅲ级(2%),Ⅳ级(2%),浆液性视网膜脱离(1%)和中心性浆液性脉络膜视网膜病变(2%)。视网膜变化与PIH严重程度呈正相关,有统计学意义(P=0.0001)。结论:8%的PIH患者视网膜发生变化,视网膜变化与PIH严重程度呈正相关。 | sahana raviraj manipur pavana acharya kavitha chikkanayakanahalli venugopal lakshmi bomalapura ramamurthy | 2017 | 国际眼科杂志2017，17，6： | 4 |
| 2 | 铁鞣新方法显示文摘将铁鞣与铬鞣进行了优化结合,这种鞣制技术不仅可以加工出质量上呈的皮革制品,同时又可以满足废液中铬与铁的含量低于100mg/kg的标准。此工艺制造的皮革可耐沸水试验,阐述了其鞣制技术和鞣制机理。对铁鞣法在加工山羊绒面革和绵羊全粒面服装革中出现的问题进行了研究。用扫描电镜对鞣革的结构特性进行了研究,对成革的物理机械性能及染色特性也做了分析和阐述。 | N K Chandra Babu R Karthikeyan R Ramesh Usha Ramamurthi T Ramasami 范贵洋 李彦春 | 2007 | 中国皮革2007，36，9： | 4 |
| 3 | Stability management of high speed axial flow compressor stage through axial extensions of bend skewed casing treatment显示文摘This paper presents the experimental results to understand the performance of moderately loaded high speed single stage transonic axial flow compressor subjected to various configurations of axial extensions of bend skewed casing treatment with moderate porosity.The bend skewed casing treatment of 33%porosity was coupled with rectangular plenum chamber of depth equal to the slots depth.The five axial extensions of 20%,40%,60%,80%and 100%were used for the experimental evaluations of compressor performance.The main objective was to identify the optimum extension of the casing treatment with reference to rotor leading edge which results in maximum stall margin improvements with minimum loss in the stage efficiency.At each axial extension the compressor performance is distinctive.The improvement in the stall margin was very significant at some axial extensions with 4%–5%penalty in the stage efficiency.The compressors stage shows recovery in terms of efficiency at lower axial extensions of 20%and 40%with increase in the peak stage efficiency.Measurements of flow parameters showed the typical behaviors at near stall flow conditions.Hot wire sensor was placed at the rotor upstream in the tip region to capture the oscillations in the inlet axial and tangential velocities at stall conditions.In the absence of casing treatment the compressor exhibit abrupt stall with very high oscillations in the inlet axial and tangential velocity of the flow.The extents of oscillations reduce with bend skewed casing treatment.Few measurements were also performed in the plenum chamber and salient results are presented in this paper. | Dilipkumar Bhanudasji Alone S.Satish Kumar Shobhavathy M.Thimmaiah Janaki Rami Reddy Mudipalli A.M.Pradeep Srinivasan Ramamurthy Venkat S.Iyengara | 2016 | Propulsion and Power Research2016，5，3： | 3 |

| 5 | 纤维蛋白胶与无缝无胶自体球结膜瓣固定术治疗翼状胬肉的疗效比较(英文)显示文摘目的:比较两种大小纤维蛋白胶与无缝无胶自体球结膜瓣固定术在原发性翼状胬肉手术中的患者舒适度、移植物稳定性、移植物炎症、复发等术后并发症。方法:本研究对2014-12/2016-08共80例翼状胬肉患者(80眼)进行前瞻性介入对比研究。研究组随机抽取并分为两组,组1接受纤维蛋白胶疗法,组2采用无缝合无胶结膜自体移植固定术。每组再将等量的受试者随机平均分为两组(组1:组A+组B,组2:组C+组D)。组A(自体移植物的大小与裸眼巩膜相同)和组B(比裸巩膜大1 mm)实施纤维蛋白胶疗法;组C(自体移植物的大小与裸眼巩膜相同)和组D(比裸巩膜大1 mm)采用无缝线无胶结膜自体移植固定术。每一位患者都接受翼状胬肉切除术,并根据组别使用不同大小的自体球结膜瓣。结果:组1平均年龄为43.525,组2平均年龄为42.2。男性20例,女性60例。37例患者右眼有翼状胬肉。四组间平均手术时长相似。在术后随访期间,除结膜下出血(纤维蛋白胶组在术后1wk内明显增多)外,4组间患者的舒适度、移植物回缩、移植物炎症和移植物水肿等术后参数均相似(P<0.0001)。组2仅3例患者出现4级移植物回缩/移位。术后1wk,组A和组D各出现1例移植囊肿患者。随访6mo后,组D中2例患者复发。结论:两种方法均安全有效,术后不适及并发症少。与纤维蛋白胶疗法相比,无缝无胶疗法更加经济且效果相当。由于该手术成本低,且具有纤维蛋白胶疗法的所有优点,无缝无胶法可被认为是治疗患者非常有效的方法。 | Manipur Raviraj Sahana Chikkanayakanahalli Venugopal Kavitha Acharya Pavana Bomalapura Ramamurthy Lakshmi | 2019 | 国际眼科杂志2019，19，11： | 2 |
