| 3 | Prognostic factors and long-term outcomes of hilar cholangiocarcinoma:A single-institution experience in China显示文摘AIM: To evaluate the prognostic factors of hilar cholangiocarcinoma in a large series of patients in a single institution.METHODS: Eight hundred and fourteen patients with a diagnosis of hilar cholangiocarcinoma that were evaluated and treated between 1990 and 2014, of which 381 patients underwent curative surgery, were included in this study. Potential factors associated with overall survival(OS) and disease-free survival(DFS) were evaluated by univariate and multivariate analyses.RESULTS: Curative surgery provided the best long-term survival with a median OS of 26.3 mo. The median DFS was 18.1 mo. Multivariate analysis showed that patients with tumor size > 3 cm [hazard ratio(HR) = 1.482, 95%CI: 1.127-1.949; P = 0.005], positive nodal disease(HR = 1.701, 95%CI: 1.346-2.149; P < 0.001), poor differentiation(HR = 2.535, 95%CI: 1.839-3.493; P < 0.001), vascular invasion(HR = 1.542, 95%CI: 1.082-2.197; P = 0.017), and positive margins(HR = 1.798, 95%CI: 1.314-2.461; P < 0.001) had poor OS outcome. The independent factors for DFS were positive nodal disease(HR = 3.383, 95%CI: 2.633-4.348; P < 0.001), poor differentiation(HR = 2.774, 95%CI: 2.012-3.823; P < 0.001), vascular invasion(HR = 2.136, 95%CI: 1.658-3.236; P < 0.001), and positive margins(HR = 1.835, 95%CI: 1.256-2.679; P < 0.001). Multiple logistic regression analysis showed that caudate lobectomy [odds ratio(OR) = 9.771, 95%CI: 4.672-20.433; P < 0.001], tumor diameter(OR = 3.772, 95%CI: 1.914-7.434; P < 0.001), surgical procedures(OR = 10.236, 95%CI: 4.738-22.116; P < 0.001), American Joint Committee On Cancer T stage(OR = 2.010, 95%CI: 1.043-3.870; P = 0.037), and vascular invasion(OR = 2.278, 95%CI: 0.997-5.207; P = 0.051) were independently associated with tumorfree margin, and surgical procedures could indirectly affect survival outcome by influencing the tumor resection margin. CONCLUSION: Tumor margin, tumor differentiation, vascular invasion, and lymph node status were independent factors for OS and DFS. Surgical procedures can indirectly affect survival outcome by influencing the tumor resection margin. | Hai-Jie Hu Hui Mao Anuj Shrestha Yong-Qiong Tan Wen-Jie Ma Qin Yang Jun-Ke Wang Nan-Sheng Cheng Fu-Yu Li | 2016 | World Journal of Gastroenterology2016,22,8: | 40 |
| 4 | Dielectric metasurfaces for complete and independent control of the optical amplitude and phase显示文摘Metasurfaces are optically thin metamaterials that promise complete control of the wavefront of light but are primarily used to control only the phase of light.Here,we present an approach,simple in concept and in practice,that uses meta-atoms with a varying degree of form birefringence and rotation angles to create high-efficiency dielectric metasurfaces that control both the optical amplitude and phase at one or two frequencies.This opens up applications in computer-generated holography,allowing faithful reproduction of both the phase and amplitude of a target holographic scene without the iterative algorithms required in phase-only holography.We demonstrate all-dielectric metasurface holograms with independent and complete control of the amplitude and phase at up to two optical frequencies simultaneously to generate two-and three-dimensional holographic objects.We show that phaseamplitude metasurfaces enable a few features not attainable in phase-only holography;these include creating artifactfree two-dimensional holographic images,encoding phase and amplitude profiles separately at the object plane,encoding intensity profiles at the metasurface and object planes separately,and controlling the surface textures of three-dimensional holographic objects. | Adam C.Overvig Sajan Shrestha Stephanie C.Malek Ming Lu Aaron Stein Changxi Zheng Nanfang Yu | 2019 | Light(Science & Applications)2019,8,1: | 27 |

| 6 | Therapeutic potential of Gastrodia elata Blume for the treatment of Alzheimer's disease显示文摘Several studies have demonstrated that the Chinese herb Gastrodia elata Blume can protect against amyloid beta-peptide (Aβ)-induced cell death. To investigate the possible therapeutic effects of Gastrodia elata Blume on Alzheimer's disease, we established a rat model of Alzheimer's disease by injecting Aβ 25-35 into bilateral hippocampi. These rats were intragastrically administered 500 or 1 000 mg/kg Gastrodia elata Blume per day for 52 consecutive days. Morris water maze tests showed that Gastrodia elata Blume treatment significantly improved the spatial memory of Alzheimer's disease rats. Congo red staining revealed that Gastrodia elata Blume significantly reduced the number of amyloid deposits in the hippocampus of these rats. Western blot analysis showed that choline acetyltransferase expression in the medial septum and hippocampus was significantly increased by the treatment of Gastrodia elata Blume,while Ellman method showed significant decrease in the activity of acetylcholinesterase in all three regions (prefrontal cortex,medial septum and hippocampus). These findings suggest that long-term administration of Gastrodia elata Blume has therapeutic potential for Alzheimer's disease. | Guang-Biao Huang Tong Zhao Sushma Shrestha Muna Hong-Mei Jin Jong-Il Park Kyu-Sik Jo Bo-Hee Lee Soo-Wan Chae Sun-Young Kim Soo-Hyun Park Eun-Ock Park Eun-Kyung Choi Young-Chul Chung | 2013 | Neural Regeneration Research2013,8,12: | 21 |

| 8 | 不同剂量右美托咪定对腹腔镜胆囊切除术中各指标及术后镇静的影响显示文摘目的腹腔镜胆囊切除术中腹内压增加和二氧化碳吸收可引起明显的交感神经兴奋,致血压升高,心率增快。有效控制这些交感反应能减少并发症,有利于患者及时恢复。文中旨在研究不同剂量右美托咪定对腹腔镜胆囊切除术中血压、心率和术后镇静的影响。方法选择2018年1月2日至2018年2月9日荆州市中心医院肝胆外科拟行择期腹腔镜胆囊切除术的患者60例。根据术中是否输注右美托咪定随机分成3组:对照组(仅泵注等量等渗盐水)、低剂量组[0.5μg/(kg·h)右美托咪定]、高剂量组[1.0μg/(kg·h)右美托咪定],每组20例。在麻醉前、切皮前、气腹后0 min、10 min、20 min、放气后即刻、拔管前、苏醒前和苏醒后各时间点记录患者血压、心率、脉氧饱和度(SpO_2)、气道峰压、呼末二氧化碳分压(PetCO_2)、拔管后Ramsay镇静评分等。结果高剂量组拔管时间、恢复室留观时间较对照组、低剂量组明显延长(P<0.05)。放气后即刻,与对照组心率[(75.60±15.59)次/min]比较,高剂量组[(64.80±8.59)次/min]、低剂量组[(65.85±10.30)次/min]明显下降(P<0.05),苏醒前、苏醒后亦明显下降(P<0.05)。气腹后0 min至放气后即刻,高剂量组气道峰压明显高于对照组、低剂量组(P<0.05)。苏醒前,高剂量组Ramsay评分[(2.65±0.48)分]明显高于对照组[(2.30±0.57)分]、低剂量组[(2.25±0.44)分],差异有统计学意义(P=0.015)。结论右美托咪定持续泵注可稳定心率,但随着泵注速度或剂量的增加,可增加拔管后的镇静深度,明显延长拔管时间及恢复室留观时间。因此临床麻醉中使用右美托咪定时以不超过0.5μg/(kg·h)为宜。 | Kumar Shrestha 王力甚 | 2018 | 医学研究生学报2018,31,12: | 17 |
| 9 | 澜沧江和怒江流域的气候变化及其对径流的影响显示文摘采用VIP(Vegetation Interface Processes)模型和HIMS(Hydro-Informatic Modeling System)模型,模拟分析了1957—2012年澜沧江和怒江流域(简称两江流域)水资源量的演变。根据CMIP5 RCP2.6,RCP4.5和RCP8.5情景预测,模拟了2030年代和2050年代流域水资源的变化。研究发现,过去50年间,两江流域的气温都呈升高趋势,但海拔较高的上游地区升幅大于下游。年总降水量的变化趋势不明显,但春季降水增加趋势明显。两江流域年总水资源量为650亿~850亿m^3,水资源总量长期变化趋势不明显,其中澜沧江的波动性(1.884,最大与最小之比)大于怒江。空间上水资源量呈现北低-南高的格局。在未来,两江流域气温仍呈增加趋势,降水呈增加趋势,径流呈增加趋势,空间变异性趋小,但较强的季节性变化对水资源安全仍具有较大的挑战性。 | 刘苏峡 丁文浩 莫兴国 王盛 刘昌明 罗贤 何大明 Sagar Ratna Bajracharya Arun Bhakta Shrestha Nand Kishor Agrawal | 2017 | 气候变化研究进展2017,13,4: | 17 |
| 10 | Nano-formulations for transdermal drug delivery:A review显示文摘Transdermal drug delivery refers to a means of delivering drugs through the surface of the skin for local or systemic treatment. The drug functions after absorption through the skin into the systemic circulation via capillary action at a certain rate. Use of traditional physical and chemical enhancers to improve the transdermal permeation rate by increasing drug solubility, diffusion coefficient, and reservoir effect is not feasible owing to the toxic side effects of the overuse of chemical penetration enhancers. Nanoformulations generally vary in size and range from 10 nm to 100 nm. The smaller particle size leads to increased drug permeability, stability, retention, and targeting, making nano-formulations suitable for transdermal drug delivery. The different applications of nano-formulations(vesicles or nanoparticles and nanoemulsions) have been widely studied. Here, the classification, characteristics, transdermal mechanism, and application of the most popular nano-formulations in transdermal drug delivery system are reviewed. | Xingli Zhou Ying Hao Liping Yuan Sushmita Pradhan Krista Shrestha Ojaswi Pradhan Hongjie Liu Wei Li | 2018 | Chinese Chemical Letters2018,29,12: | 17 |

| 12 | 钢管混凝土拱桥徐变影响分析显示文摘基于龄期调整有效模量法推导出钢管混凝土轴心受压构件徐变系数公式,采用该公式对钢管混凝土轴心受压构件进行徐变分析。由徐变预测结果与试验数据比较可知,在CEB-FIP 78、CEB-FIP 90及ACI 209R等3种典型徐变系数模式中,ACI 209R模式较其它两种徐变系数模式更为合理。采用ACI 209R徐变系数模式对1座跨径380 m的大跨钢管混凝土铁路拱桥进行徐变分析,并与CEB-FIP 78模式计算结果进行比较,结论可为其它钢管混凝土拱桥的徐变分析提供参考。 | 李生勇 李凤芹 陈宝春 K M SHRESTHA | 2011 | 铁道学报2011,33,3: | 13 |
| 13 | Broadband achromatic dielectric metalenses显示文摘Metasurfaces offer a unique platform to precisely control optical wavefronts and enable the realization of flat lenses,or metalenses,which have the potential to substantially reduce the size and complexity of imaging systems and to realize new imaging modalities.However,it is a major challenge to create achromatic metalenses that produce a single focal length over a broad wavelength range because of the difficulty in simultaneously engineering phase profiles at distinct wavelengths on a single metasurface.For practical applications,there is a further challenge to create broadband achromatic metalenses that work in the transmission mode for incident light waves with any arbitrary polarization state.We developed a design methodology and created libraries of meta-units—building blocks of metasurfaces—with complex cross-sectional geometries to provide diverse phase dispersions(phase as a function of wavelength),which is crucial for creating broadband achromatic metalenses.We elucidated the fundamental limitations of achromatic metalens performance by deriving mathematical equations that govern the tradeoffs between phase dispersion and achievable lens parameters,including the lens diameter,numerical aperture(NA),and bandwidth of achromatic operation.We experimentally demonstrated several dielectric achromatic metalenses reaching the fundamental limitations.These metalenses work in the transmission mode with polarization-independent focusing efficiencies up to 50%and continuously provide a near-constant focal length over λ=1200–1650 nm.These unprecedented properties represent a major advance compared to the state of the art and a major step toward practical implementations of metalenses. | Sajan Shrestha Adam C.Overvig Ming Lu Aaron Stein Nanfang Yu | 2018 | Light(Science & Applications)2018,7,1: | 13 |
| 14 | Xanthogranulomatous cholecystitis mimicking gallbladder carcinoma:An analysis of 42 cases显示文摘AIM: To review and evaluate the diagnostic dilemma of xanthogranulomatous cholecystitis(XGC) clinically.METHODS: From July 2008 to June 2014, a total of 142 cases of pathologically diagnosed XGC were reviewed at our hospital, among which 42 were misdiagnosed as gallbladder carcinoma(GBC) based on preoperative radiographs and/or intra-operative findings. The clinical characteristics, preoperative imaging, intra-operative findings, frozen section(FS) analysis and surgical procedure data of these patients were collected and analyzed.RESULTS: The most common clinical syndrome in these 42 patients was chronic cholecystitis, followed by acute cholecystitis. Seven(17%) cases presented with mild jaundice without choledocholithiasis. Thirtyfive(83%) cases presented with heterogeneous enhancement within thickened gallbladder walls on imaging, and 29(69%) cases presented with abnormal enhancement in hepatic parenchyma neighboring the gallbladder, which indicated hepatic infiltration. Intra-operatively, adhesions to adjacent organs were observed in 40(95.2%) cases, including the duodenum, colon and stomach. Thirty cases underwent FS analysis and the remainder did not. The accuracy rate of FS was 93%, and that of surgeon's macroscopic diagnosis was 50%. Six cases were misidentified as GBC by surgeon's macroscopic examination and underwent aggressive surgical treatment. No statistical difference was encountered in the incidence of postoperative complications between total cholecystectomy and subtotal cholecystectomy groups(21% vs 20%, P > 0.05).CONCLUSION: Neither clinical manifestations and laboratory tests nor radiological methods provide apractical and effective standard in the differential diagnosis between XGC and GBC. | Yi-Lei Deng Nan-Sheng Cheng Shui-Jun Zhang Wen-Jie Ma Anuj Shrestha Fu-Yu Li Fei-Long Xu Long-Shuan Zhao | 2015 | World Journal of Gastroenterology2015,21,44: | 13 |

| 16 | Successful conservative management with methotrexate and mifepristone of cervical pregnancy显示文摘This study investigated possible effective treatments for cervical pregnancy, a rare form of ectopic pregnancy. The clinical records of 11 cases of ectopic pregnancy admitted to the Third Affiliated Hospital of Sun Yat-sen University from 1998 to 2010 were analyzed. All patients were treated with intermuscular injection of methotrexate (MTX, 50 mg), and oral mifepristone (25 mg, bid). All cases were successfully cured by conservative treatments using methotrexate plus mifepristone. Cervical pregnancy is a contributive factor to mutiple abortions and curettages. Methotrexate plus mifepristone, curettage through hysteroscopy and intracervical obturation with gauze are effective treatments of cervical pregnancy without the need for surgical intervention. | Eliza Shrestha | 2011 | The Journal of Biomedical Research2011,25,1: | 11 |
| 17 | Basic life support:knowledge and attitude of medical/paramedical professionals显示文摘BACKGROUND:Basic life support(BLS),a key component of the chain of survival decreases the arrest-cardiopulmonary resuscitation interval and increases the rate of hospital discharge.The study aimed to explore the knowledge of and attitude towards basic life support(BLS)among medical/paramedical professionals.METHODS:An observational study was conducted by assessing response to self prepared questionnaire consisting of the demographic information of the medical/paramedical staff,their personnel experience/attitude and knowledge of BLS based on the 2005 BLS Guidelines of European Resuscitation Council.RESULTS:After excluding incomplete questionnaires,the data from 121 responders(27 clinical faculty members,21 dental and basic sciences faculty members,29 house officers and 44 nurses and health assistants)were analyzed.Only 9(7.4%)of the 121 responders answered≥11,53(43%)answered 7-10,and 58(48%)answered<7 of 15 questions correctly.The clinical faculty members,house officers and nurses/HA had a mean score of 7.4±3.15,7.37±2.02 and 6.63±2.16 respectively,while dental/basic sciences faculty members attained a least mean score of 4.52±2.13(P<0.001).Those who had received cardiopulmonary resuscitation(CPR)training within 5 years obtained a highest mean score of 8.62±2.49,whereas those who had the training more than 5 years back or no training obtained a mean score of 5.54±2.38 and 6.1±2.29 respectively(P=0.001).Those who were involved in resuscitation frequently had a higher median score of 8 in comparison to those who were seldom involved or not involved at all(P<0.001).CONCLUSIONS:The average health personnel in our hospital lack adequate knowledge in CPR/BLS.Training and experience can enhance knowledge of CPR of these personnel.Thus standard of CPR/BLS training and assessment are recommended at our hospital. | Shrestha Roshana Batajoo KH Piryani RM Sharma MW | 2012 | World Journal of Emergency Medicine2012,3,2: | 11 |
