4桑叶多糖对早期断奶仔猪生长性能、腹泻、血液指标和肠道菌群的影响显示文摘研究旨在探讨日粮补充桑叶多糖(MLPs)对早期断奶仔猪生长性能、腹泻、血液生化指标和肠道菌群的影响。共选取(28±2)日龄、体重为(9.18±0.46)kg的'杜洛克×长白×约克夏'杂交断奶仔猪150头,随机分成5个处理组,每组6个重复,每个重复5头猪。饮食处理如下:对照组(CT):基础日粮(BD);低剂量桑叶多糖组(LT):0.3 g·kg-1MLPs+BD;中剂量桑叶多糖组(MT):0.6 g·kg-1MLPs+BD;高剂量桑叶多糖组(HT):0.9 g·kg-1MLPs+BD;抗生素处理组(AT):0.15 g·kg-1金霉素+BD。分别在第0、10、21天的早晨,每头猪空腹测量体重并记录采食量,这些数据用来计算平均日增重(ADG)、平均日采食量(ADFI)和料重比(F/G)。每天两次(上午和下午)对每头仔猪的腹泻状况进行检查并记录。在试验结束时,收集血液样本用于生化分析,并收集盲肠、结肠和直肠内容物进行识别和量化相关的肠道菌群。研究结果表明,MLPs处理组间的日增重、平均日采食量和料重比无显著差异(P>0.05),但低剂量组(LT)、中剂量组(MT)、高剂量组(HT)的平均日采食量高于对照组(CT)和抗生素组(AT)。并且,LT、MT和HT组的料重比低于CT和AT组。与CT和AT组相比,LT、MT和HT组仔猪的腹泻发病率也显著降低(P<0.05)。生化分析表明,MLPs各处理组仔猪的血糖(GLU)水平均显著低于CT或AT组(P<0.05)。MT和HT组血液尿素氮(BUN)水平与CT和AT组存在显著差异(P<0.05),HT组T3水平显著高于CT和AT组(P<0.05)。虽然MLPs各处理组的T4水平与AT组并没有显著差异(P>0.05),但MT组的胰岛素样生长因子Ⅰ(IGF-Ⅰ)和生长激素(GH)水平较CT或AT组均显著升高(P<0.05)。LT、MT和HT 3组在抑制肠道大肠杆菌生长和促进肠道乳酸杆菌和双歧杆菌生长的整体效果上均优于CT和AT组。值得注意的是,与CT和AT组相比,HT组(0.9 g·kg-1MLPs)对抑制肠道大肠杆菌以及促进肠道有益菌群具有更显著效果(P<0.05)。结果表明,日粮添加桑叶多糖可以改善早期断奶仔猪肠道菌群的生态环境,降低腹泻率,提高整体生长性能。Zhao X J Lin L Luo Q L Ye M Q Luo G Q Kuang Z S 2015饲料博览2015,0,7:7

6Characterisation of Neonicotinoid and Pymetrozine Resistance in Strains of Bemisia tabaci(Hemiptera:Aleyrodidae)from China显示文摘Four strains of the Q biotype and one of the B biotype of the whitefly Bemisia tabaci collected from China were characterised for resistance to four neonicotinoid insecticides and pymetrozine.Q biotype strains showed moderate to strong resistance to imidacloprid,thiamethoxam and acetamiprid,but little or no cross-resistance to dinotefuron.Resistance to neonicotinoids was consistently associated with resistance to pymetrozine,despite the latter having a distinct(though unresolved)mode of action.The single B biotype strain proved largely susceptible to all the insecticides investigated.Resistance in the Q biotype strains was associated with over-expression of a cytochrome P450 monooxygenase gene,CYP6CM1,whose substrate specificity presumably accounts for the observed cross-resistance profiles.RAO Qiong XU Yong-hua LUO Chen ZHANG Hong-yu Christopher M Jones Greg J Devine KevinGorman Ian Denholm 2012Journal of Integrative Agriculture2012,11,2:7
7肠系膜下动脉根部淋巴结清扫联合血管低位或高位结扎治疗直肠癌的效果观察显示文摘目的:在结直肠癌手术中,与肠系膜下动脉高位结扎相比,保留左结肠动脉的低位结扎在淋巴结清扫、吻合口漏和肿瘤学结果方面仍存在争议。本研究通过回顾性病例分析探讨腹腔镜直肠癌前切除术中肠系膜下动脉高位结扎或低位结扎对患者近期和远期疗效的影响。方法:回顾性分析2013年至2016年在仁济医院行腹腔镜直肠癌前切除术的614例患者的临床资料,比较低位结扎组和高位结扎组的临床人口学特征、手术时间、IMA根部淋巴结清扫数目、围手术期并发症、术后3年和术后5年的总生存率和无病生存率。两组之间比较采用t检验或χ^(2)检验,生存率采用Kaplan-Meier生存曲线以及Log-rank检验分析。以P<0.05为差异有统计学意义。孙凌宇 俞旻皓 骆洋 LUO Y YU M H HUANG Y Z 2021结直肠肛门外科2021,27,4:6

11Modified technique of advanced core decompression for treatment of femoral head osteonecrosis显示文摘BACKGROUND Osteonecrosis of the femoral head(ONFH)is a destructive condition most commonly affecting young and middle-aged patients.The leading consequence of ONFH is often a significant articular disability.Effective joint-preserving surgical treatments are urgently needed for patients with early stage ONFH when outcomes of treatment are in general better than the advanced stage disease.AIM To introduce a new surgery procedure called percutaneous expanded core decompression and mixed bone graft technique,which is a new way of jointpreserving surgical treatments.METHODS The clinical data of 6 patients with ONFH diagnosed and treated with the procedure called percutaneous expanded core decompression and mixed bone graft technique at The First Hospital of Qiqihar from March 2013 to August 2019 were retrospectively analyzed;the follow-up ended in December 2019.RESULTS There were 6 male patients with an average age of 43 years in our study.Gratifying results have been obtained from the comparison of Harris hip score,visual analogue scale,and imaging examination before and after operation.CONCLUSION This new modified technique is simple,safe,and reliable.No serious perioperative complications were observed in our cases.Advantages of the single blade expandable reamer are obvious.The adjuvant substance is inexpensive and easy to obtain.Thus,this technique is an effective joint-preserving surgical treatment for patients with early stage of ONFH.Lin Lin Yan Jiao Xian-Guo Luo Jin-Zhu Zhang He-Liang Yin Li Ma Bo-Ran Chen Derek M Kelly Wei-Kuan Gu Hong Chen 2020World Journal of Clinical Cases2020,8,13:3

14Terahertz Semiconductor Quantum Well Devices显示文摘For eventually providing terahertz science with compact and convenient devices,terahertz (1~10THz) quantum-well photodetectors and quantum-cascade lasers are investigated.The design and projected detector performance are presented together with experimental results for several test devices,all working at photon energies below and around optical phonons.Background limited infrared performance (BLIP) operations are observed for all samples (three in total),designed for different wavelengths.BLIP temperatures of 17,13,and 12K are achieved for peak detection frequencies of 9.7THz(31μm),5.4THz(56μm),and 3.2THz(93μm),respectively.A set of THz quantum-cascade lasers with identical device parameters except for doping concentration is studied.The δ-doping density for each period varies from 3.2×1010 to 4.8×1010cm-2.We observe that the lasing threshold current density increases monotonically with doping concentration.Moreover,the measurements for devices with different cavity lengths provide evidence that the free carrier absorption causes the waveguide loss also to increase monotonically.Interestingly the observed maximum lasing temperature is best at a doping density of 3.6×1010cm-2.Liu H C Luo H Ban D Waichter M Song C Y Wasilewski Z R Buchanan M Aers G C SpringThorpe A J Cao J C Feng S L Williams B S Hu Q 2006Journal of Semiconductors2006,27,4:2
15纳米光子结构软膜紫外光固化纳米压印(英文)显示文摘紫外光固化纳米压印是实现纳米结构批量复制的一种新技术.其特点是低成本和高分辨,而且可以达到极高的套刻精度.为了得到大面积图案的均匀复制,可用聚二甲基硅氧烷(PDMS)制备透光的压印软模板.其母版图案可由高分辨率电子束曝光和反应离子刻蚀的方法在硅片基底上获得,然后用浇注的方法将图案转移到PDMS上.本实验特别发展了紫外光固化纳米压印适用于软膜压印的双层膜图型转移技术.该双层膜由廉价的光胶和聚甲基丙烯酸甲脂(PMMA)构成.对光胶层的压印可用普通的光学曝光仪实现.然后再将图案用反应离子刻蚀的方法转移到PMMA层中.为了证明方案的可行性,在两种不同材料的半导体基片上压印了三角晶格的光子晶体和准晶结构的图案,并用剥离的方法将它们转移到金属薄膜上,最后成功地进行了硅片刻蚀实验.相信这一纳米制做方法对大面积纳米光子结构和光学集成芯片的制造是普遍适用的.SHI J WANG Z M BAO K PEROZ C BELOTTI M XU L P LUO C X SUN M H ZHANG B JI H OUYANG Q CHEN Y 2006纳米技术与精密工程2006,4,3:2

20Hepatology Research|预测慢性乙型肝炎患者何时停用核苷(酸)类似物及停药后乙型肝炎复发的生物标志物显示文摘HBV感染是一个严重的全球健康问题。目前有两大类药物被推荐用于治疗HBV感染,包括核苷(酸)类似物和干扰素。由于接受核苷(酸)类似物治疗的患者较难实现停药后功能性治愈,需要长期的核苷(酸)类似物治疗;并且一旦过早停药,复发和肝炎恶化的可能性会增加。近年研究表明,HBeAg阴性患者停止长期核苷(酸)类似物治疗后,相对较高比例的患者保持了无治疗缓解状态,甚至实现了HBsAg清除。这些发现对终身服用核苷(酸)类似物的必要性提出了挑战。南方医科大学南方医院的Luo等对可以预测核苷(酸)类似物停药的病毒学指标进行了综述。检索的数据库为PubMed,使用慢性乙型肝炎、预测、停药等关键词按条件进行检索,最终对84篇文章进行了综述。蒋德科 LUO M ZHOU B HOU J 2022临床肝胆病杂志2022,38,6:2
