12019新型冠状病毒基因组特征和流行病学:病毒起源和受体结合的意义显示文摘研究者对来自9例新型冠状病毒肺炎住院患者的支气管肺泡灌洗液样本和培养的分离株进行了下一代测序。从这些个体中获得了严重急性呼吸综合征-冠状病毒2(severe acute respiratory syndrome-coronavirus 2,SARS-CoV-2)的完整和部分基因组序列。利用Sanger测序连接病毒重叠群以获得全长基因组,cDNA末端快速扩增确定终端区。对这些SARSCoV-2基因组和其他冠状病毒基因组进行了系统进化分析,以确定该病毒的进化史并有助于推断其可能的起源。刘青(译) 刘莉(审校) Lu R Zhao X Li J Niu P Yang B Wu H Wang W Song H Huang B Zhu N Bi Y Ma X Zhan F Wang L Hu T Zhou H Hu Z Zhou W Zhao L Chen J Meng Y Wang J Lin Y Yuan J Xie Z Ma J Liu WJ Wang D Xu W Holmes EC Gao GF Wu G Chen W Shi W Tan W 2020中华高血压杂志2020,28,3:516
2Study of the mechanisms of acupuncture and moxibustion treatmentfor ulcerative colitis ratsinview of the gene expression of cytokines显示文摘AIM To observe the effect of acupuncture and moxibustion on the expression of IL 1β and IL 6 mRNA in ulcerative colitis rats. METHODS The SD rat ulcerative colitis model was created by immunological method associated with local stimulation. Colonic mucosa was prepared from human fresh surgical colonic specimens, homogenized by adding appropriate amount of normal saline and centrifuged at 3000*!r/*!min . The supernatant was collected for measurement of protein conentration and then mixed with Freund adjuvant. This antigen fluid was first injected into the plantae of the model group rats, and then into their plantae, dorsa, inguina and abdominal cavities (no Freund adjuvant for the last injection) again on the 10th, 17th, 24th and 31st day. When a certain titer of serum anti colonic antibody was reached, 2% formalin and antigen fluid (no Freund adjuvant) were administered separately by enema. The ulcerative colitis rat model was thus set up. The animals were randomly divided into four groups: model control group (MC, n =8), electro acupuncture group (EA, n =8), herbs partition moxibustion group (HPM 8), normal control group (NC, n =8). HPM: Moxa cones made of refined mugwort floss were placed on the medicinal pad (medicinal pad dispensing: Radix Aconiti praeparata, cortex Cinnamomi, etc ) for Qihai (RN 6) and Tianshu (ST 25, bilateral) and ignited. Two moxa cones were used for each acupoint once a day and 14 times in all. EA: Tianshu (bilateral) and Qihai were stimulated by the intermittent pulse with 2Hz frequency, 4mA intensity for 20 minutes once a day and 14 times in all. After treatment, rats of all four groups were killed simultaneously. The spleen was separated and the distal colon was dissected. Total tissue RNA was isolated by the guanidinium thiocyanate phenol chloroform extraction method. RT PCR technique was used to study the expression of IL 1β and IL 6 mRNA. RESULTS IL 1β and IL 6 mRNAs were not detected in the spleen and colonic mucosa of the NC rats, whereas they were significantly expressed in that of the MC rats. IL 1β and IL 6 mRNAs were markedly lower in the EA and HPM rats than that in MC rats. There was no significant difference between the levels of IL 1β and IL 6 mRNAs in the EA and HPM rats. The expressions of IL 1β and IL 6 mRNAs were nearly the same in the spleen and colon of all groups. CONCLUSION Acupuncture and moxibustion greatly inhibited the expression of IL 1β and IL 6 mRNA in the experimental ulcerative colitis rats.Wu HG Zhou LB Pan YY Huang C Chen HP Shi Z Hua XG 1999World Journal of Gastroenterology1999,5,6:45

7Magnetic resonance evaluation of transplanted mesenchymal stem cells after myocardial infarction in swine显示文摘Objectives To trace and evaluate intracoronary transplanted mesenchymal stem cells(MSCs) labeled with superparamagnetic iron oxide(SPIO) by using magnetic resonance imaging(MRI) in a swine model of myocardial infarction (MI).Methods MSCs were transfected with a lentiviral vector carrying the gene encoding green fluorescent protein (GFP) and labeled in vitro with SPIO.Two weeks after MI, swine were randomized to intracoronary transplantation of dual -labeled MSCs(n = 10),MSCs-GFP(n = 10) and saline(n = 5).MRI examination was performed with a 1.5T clinical scanner at 24 hours,3 weeks and 8 weeks after cells transplantation. Signal intensity(SI) changes,cardiac function and MI size were measured using MRI.Correlation between MR findings and histomorphologic findings was also investigated. Results The labeling efficiency at a combination of 25μg Fe/ml SPIO and 0.8 pi/ml Lipofectamine 2000 reached 100%.SPIO labeling did not affect GFP fluorescence and dual-labeling did not affect cell proliferation(P>0.05). Multipotentiality was not affected especially for cardiomyocyte-like cells differentiation.Cardiac cell marker of a-MHC and actinin were positively expressed by immunofluorescence staining after induction.SI on T2 * WI decreased substantial- ly in the interventricular septum 24 hours after injection of MSCs.The intensity of hypo-intense signals appeared to increase throughout the later time points.Changes in SI at 24 hours,3 weeks and 8 weeks were 52.98%±10.74%,21.53%±5.40%and 6.23%±2.01%,respectively(P<0.01).DE-MRI demonstrated both dual-labeled MSCSs and MSCs-GFP could dramatically reduce the size of MI and improve cardiac function. Histological data revealed that prussian blue stain-positive cells were found mainly in the border zone which also showed green fluorescence but negative for macrophage marker(CD68).Gross pathologic examination revealed that engrafted MSCs dramatically reduce the extent of necrotic myocardium and promote the regeneration of new,contractile myocardium along the subendocardial surface of the MI. Conclusions MSCs could be efficiently and safely labeled with SPIO and GFP,and could be detected reproducibly and noninvasively in vivo using cardiac MRI.Intracoronary transplantation of dual-labeled MSCs could increase cardiac function and reduce the size of MI.KE Yang~1,PENG Chao-quan~1,XIANG Peng~1,ZHANG Cheng-xi~1, ZOU Li-yuan~1,WU Xiao~1,YA Gao~1,KANG Z huang~2,HE Ke-ke~2,LIU Jin-lai~1 (1.Department of Cardiology,The Third Affiliated Hospital, Sun Yat-sen University,Guangzhou 2.Department of Radiology, the Third Affiliated Hospital,Sun Yat-sen University, Guangzhou 5100630 3.Center for Stem Cell Biology and Tissue Engineering,Sun Yat-sen University,Guangzhou 5100120) 2011岭南心血管病杂志2011,17,S1:7
8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
9High efficiency, high power 808nm laser array and stacked arrays optimized for elevated temperature operation显示文摘Operation of 808-nm laser diode pumping at elevated temperature is crucial to many applications. Reliable operation at high power is limited by high thermal load and low catastrophic optical mirror damage (COMD) threshold at elevated temperature range. We demonstrated high efficiency and high power operation at elevated temperature with high COMD power. These results were achieved through device design optimization such as growth conditions, doping profile, and materials composition of the quantum-well and other layers. Electrical-to-optical efficiency as high as 62% was obtained through lowered threshold current, lowered series resistance and increased slope efficiency. The performance of single broad-area laser diodes scales to that of high power single bars on water-cooled copper micro-channel heatsinks or conductively-cooled CS heatsinks. No reduction in bar performance or significant spectral broadening is seen when these micro-channel coolers are assembled into 6-bar and 18-bar CW stacks for the highest power levels.Crump P A Crum T R DeVito M Farmer J Grimshaw M Huang Z Igl S A Macomber S Thiagarajan P Wise D 2004光机电信息2004,21,6:4
10BMC Medicine论文摘要汇编——糖尿病用药管理支持:糖尿病自我管理应用程序的系统评估显示文摘背景在糖尿病自我管理支持方面,智能手机应用程序越来越受欢迎。糖尿病自我管理的一个重要方面是恰当服药。本研究旨在系统地评估和描述糖尿病自我管理应用程序中的用药管理功能,及其与基于证据的最佳实践标准的一致性。方法 2018年6月,在Google Play和Apple应用程序商店中,使用英语搜索糖尿病相关术语。根据国际用药管理和糖尿病指南的评估标准,下载并评估具有用药和血糖管理功能的应用程序。结果共搜索到3 369个Android和1 799个iOS潜在相关的应用程序;其中,143个应用程序(81个Android,62个iOS)符合纳入标准,并已下载和评估。超过一半[58.0%(83/143)]的应用程序具有用药提醒功能;16.8%(24/143)的应用程序具有审查药物依从性的功能;39.9%(57/143)的应用程序允许进入服药指示;5.6%(8/143)的应用程序提供药物相关信息;4.2%(6/143)的应用程序显示鼓励服药的激励消息。只有两个应用程序鼓励用户采用辅助性疗法。在应用评估期间,观察到诸如有限的药物记录容量、错误的提醒功能、不明确的药物依从性评估,以及视觉上过度分散注意力的广告等问题。结论大部分糖尿病自我管理应用程序缺乏增强用药依从性和安全性的功能。应更加重视糖尿病应用程序中用药管理功能的设计,以提高其与基于证据的最佳实践标准的一致性。本刊编辑部(编译) HUANG Z LUM E JIMENEZ G 2019中国全科医学2019,22,29:4
