| 1 | Collagen/hyaluronan based hydrogels releasing sulfated hyaluronan improve dermal wound healing in diabetic mice via reducing inflammatory macrophage activity显示文摘Sustained inflammation associated with dysregulated macrophage activation prevents tissue formation and healing of chronic wounds.Control of inflammation and immune cell functions thus represents a promising approach in the development of advanced therapeutic strategies.Here we describe immunomodulatory hyaluronan/collagen(HA-AC/coll)-based hydrogels containing high-sulfated hyaluronan(sHA)as immunoregulatory component for the modulation of inflammatory macrophage activities in disturbed wound healing.Solute sHA downregulates inflammatory activities of bone marrow-derived and tissue-resident macrophages in vitro.This further affects macrophage-mediated pro-inflammatory activation of skin cells as shown in skin ex-vivo cultures.In a mouse model of acute skin inflammation,intradermal injection of sHA downregulates the inflammatory processes in the skin.This is associated with the promotion of an anti-inflammatory gene signature in skin macrophages indicating a shift of their activation profile.For in vivo translation,we designed HA-AC/coll hydrogels allowing delivery of sHA into wounds over a period of at least one week.Their immunoregulatory capacity was analyzed in a translational experimental approach in skin wounds of diabetic db/db mice,an established model for disturbed wound healing.The sHA-releasing hydrogels improved defective tissue repair with reduced inflammation,augmented pro-regenerative macrophage activation,increased vascularization,and accelerated new tissue formation and wound closure. | Sophia Hauck Paula Zager Norbert Halfter Elke Wandel Marta Torregrossa Ainur Kakpenova Sandra Rother Michelle Ordieres Susann Räthel Albrecht Berg Stephanie Möller Matthias Schnabelrauch Jan C.Simon Vera Hintze Sandra Franz | 2021 | Bioactive Materials2021，6，12： | 7 |
| 2 | Relationship between HER-2 overexpression and brain metastasis in esophageal cancer patients显示文摘AIM:To study if HER-2 overexpression by locally advanced esophageal cancers increase the chance of brain metastasis following esophagectomy.METHODS:We retrospectively reviewed the medical records of esophageal cancer patients who underwent esophagectomy at University of Iowa Hospitals and Clinics between 2000 and 2010.Data analyzed consisted of demographic and clinical variables.The brain metastasis tissue was assayed for HER-2 overexpression utilizing the FDA approved DAKO Hercept Test.RESULTS:One hundred and forty two patients were reviewed.Median age was 64 years(36-86 years).Eighty eight patients(62%) received neoadjuvant chemoradiotherapy.Pathological complete and partial responses were achieved in 17(19%) and 71(81%) patients.Cancer relapsed in 43/142(30%) patients.The brain was the first site of relapse in 9/43 patients(21%,95% CI:10%-36%).HER-2 immunohistochemistry testing of the brain metastasis tissue showed that 5/9(56%) cases overexpressed HER-2(3+ staining).CONCLUSION:HER-2 overexpression might be associated with increased risk of brain metastasis in esophageal cancer patients following esophagectomy.Further studies will be required to validate this observation. | Taher Abu Hejleh Barry R DeYoung Eric Engelman Jeremy M Deutsch Bridget Zimmerman Thorvardur R Halfdanarson Daniel J Berg Kalpaj R Parekh William R Lynch Mark D Iannettoni Sudershan Bhatia Gerald Clamon | 2012 | World Journal of Gastrointestinal Oncology2012，4，5： | 5 |
| 3 | 异源nifA基因对苜蓿中华根瘤菌nifA突变体的互补分析显示文摘为深入研究苜蓿中华根瘤菌NifA的特性,分别用组成型表达的慢生型大豆根瘤菌和紫云英根瘤菌的nifA基因互补苜蓿中华根瘤菌nifA突变体,观察其共生表型.结果表明,慢生型大豆根瘤菌和紫云英根瘤菌nifA基因不能互补苜蓿中华根瘤菌nifA突变体的共生表型.以苜蓿中华根瘤菌nifA突变体为遗传背景,利用全基因组微阵列实验比较分析引入异源nifA基因后产生的基因表达谱的变化.结果显示,苜蓿中华根瘤菌自身NifA蛋白引起238个基因的表达发生变化.这些表达差异的基因分属共生、能量和中心代谢、持家、细胞结构与运输等生物学功能组.慢生型大豆根瘤菌、紫云英根瘤菌和阴沟肠杆菌的NifA蛋白分别引起了20,7和9个基因的表达发生变化.这些基因主要是固氮相关基因,但差异不及苜蓿中华根瘤菌NifA互补菌明显.以苜蓿中华根瘤菌nifH启动子与lacZ融合基因为报道基因,研究nifH的表达.结果指出,慢生型大豆根瘤菌和紫云英根瘤菌的NifA蛋白只能部分激活苜蓿中华根瘤菌nifH的表达,激活水平分别为苜蓿中华根瘤菌NifA蛋白激活率的70%和50%,与微阵列实验结果相符. | 姚振华 田哲贤 戴小密 Anke Becker 李健 严海芹 肖琰 朱家璧 俞冠翘 Silvia Rüberg 王忆平 邹华松 | 2006 | 科学通报2006，51，19： | 4 |
| 4 | nifA突变的苜蓿根瘤菌在根瘤中的转录组学分析显示文摘用全基因组微阵列比较了根瘤中苜蓿根瘤菌1021的nifA突变菌和野生菌的基因表达谱.分析结果表明,nifA的缺失引起601个基因的表达发生变化.这些基因分别属于生物大分子的合成代谢、三羧酸循环及呼吸代谢以及结瘤固氮过程等多个功能组,预示着根瘤中细菌的生长状态发生了显著的变化.在根瘤中,fixK以及受其激活的基因在nifA突变菌中的表达量显著高于野生菌.定量实时PCR分析表明,根瘤中fixLJ的转录水平在nifA突变菌中显著高于野生菌.通过统计学方法从13个表达发生显著变化的基因的上游调控序列中找到推测的NifA结合位点. | 田哲贤 邹华松 李健 张远涛 刘影 俞冠翘 朱家璧 Silvia Rüberg Anke Becker 王忆平 | 2006 | 科学通报2006，51，15： | 3 |

| 6 | Second-generation direct-acting-antiviral hepatitis C virus treatment: Efficacy, safety, and predictors of SVR12显示文摘AIM To gather data on the antiviral efficacy and safety of second generation direct acting antiviral(DAA) treatment with respect to sustained virological response(SVR) 12 wk after conclusion of treatment, and to determine predictors of SVR12 in this setting.METHODS Two hundred and sixty patients treated with SOF combination partners PR(n = 51), R(n = 10), SMV(n = 30), DCV(n = 81), LDV(n = 73), or 3D(n = 15).144/260 were pre-treated, 89/260 had liver cirrhosis, 56/260 had portal hypertension with platelets < 100/nL, 25/260 had a MELD score ≥ 10 and 17/260 were postliver transplantation patients. 194/260 had HCV GT1, 44/260 HCV GT3.RESULTS Two hundred and forty/256(93.7%) patients achieved SVR12(m ITT); 4/260 were lost to follow-up. SVR12 rates for subgroups were: 92% for SOF/DCV, 93% for each SOF/SMV, SOF/PR, 94% for SOF/LDV, 100% for 3D, 94% for pretreated, 87% for liver cirrhosis, 82% for patients with platelets < 100/n L, 88% post-liver transplantation, 95% for GT1 a, 93% for GT1 b, 90% for GT3, 100% for GT2, 4, and 6. 12 patients suffered from relapse, 6 prematurely discontinued treatment, of which 4 died. Negative predictors of SVR12 were a platelet count < 100/nL, MELD score ≥ 10(P < 0.0001), liver cirrhosis(P = 0.005) at baseline. In Interferonfree treatment GT3 had significantly lower SVR rates than GT1(P = 0.016). Side effects were mild. CONCLUSION Excellent SVR12 rates and the favorable side-effect profile of DAA-combination therapy can be well translated into 'real-world'. Patients with advanced liver disease, signs of portal hypertension, especially with platelets < 100/n L and patients with GT3 are in special need for further research efforts to overcome comparatively higher rates of virological failure. | Christoph R Werner Julia M Schwarz Daniel P Egetemeyr Robert Beck Nisar P Malek Ulrich M Lauer Christoph P Berg | 2016 | World Journal of Gastroenterology2016，22，35： | 2 |

| 9 | Pericytes synthesize renin显示文摘AIM: To investigate renin expression in pericytes during normal kidney development and after deletion of angiotensinogen, the precursor for all angiotensins.METHODS: We examined the distribution of renin expressing cells by immunoshistochemistry in the interstitial compartment of wild type(WT) and angiotensinogen deficient(AGT-/-) mice at different developmental stages from embryonic day 18(E18: WT, n = 4; AGT-/-, n = 5) and at day 1(P1: WT, n = 5; AGT-/-, n = 5), 5(P5: WT, n = 7; AGT-/-, n = 8), 10(P10: WT, n = 3; AGT-/-, n = 5), 21(P21: WT, n = 7; AGT-/-, n = 5), 45(P45: WT, n = 3; AGT-/-, n = 3), and 70(P70: WT, n = 2; AGT-/-, n = 2) of postnatal life. We quantified the number of pericytes positive for renin at all the developmental stages mentioned above and comparedthe results of AGT-/- mice to their WT counterparts.RESULTS: In WT mice, renal interstitial pericytes synthesize renin in early life supporting a lineage relationship with renin cells in the vasculature. The number of pericytes positive for renin per area of 0.32 mm2(density) in WT mice was maintained from fetal life till weaning age(E18 = 4.25 ± 0.63, P1 = 3.75 ± 0.48, P5 = 3.75 ± 0.48, P10 = 4 ± 0.71, P21 = 3.8 ± 0.58) and markedly decreased in adult life(P45 = 1.2 ± 0.37, P70 = 0.8 ± 0.20). On the other hand, in AGT-/- mice the density of pericytes expressing renin was not significantly different from WT mice at E18 and P1: E18 = 5.75 ± 0.50 vs 4.25 ± 0.63(P = 0.106), P1 = 9.25 ± 3.50 vs 3.75 ± 0.48(P = 0.175) but significantly increased from P5 till P70: P5 = 38.25 ± 5 vs 3.75 ± 0.48(P = 0.0004), P10 = 173 ± 7.50 vs 4 ± 0.70(P = 5.24567 × 10-7), P21 = 83 ± 6.70 vs 3.8 ± 0.58(P = 2.97358 × 10-6), P45 = 49 ± 3.50 vs 1.2 ± 0.37(P = 8.18274 x 10-7) and P70 = 17.8 ± 2.30 vs 0.8 ± 0.20(P = 3.51151 × 10-5). The AGT-/- mice showed a marked increase in the number of pericytes per field studied starting from P5, reaching its peak at P10, and then a gradually decreasing until P70. CONCLUSION: Interstitial pericytes synthesize renin during development and the number of renin-expressing pericytes increases in response to a homeostatic threat imposed early in life such as lack of angiotensinogen. | Alison C Berg Catalina Chernavvsky-Sequeira Jennifer Lindsey R Ariel Gomez Maria Luisa S Sequeira-Lopez | 2013 | World Journal of Nephrology2013，2，1： | 2 |
