| 1 | 我国6个地方绵羊品种微卫星DNA多态性研究(英文)显示文摘利用聚丙烯酰胺凝胶电泳技术研究了我国蒙古羊、乌珠穆沁羊、哈萨克羊、阿勒泰羊、滩羊和藏绵羊 6个地方绵羊品种 17个微卫星标记的多态性 ,以探讨其遗传多样性、起源分化及群体间的遗传亲缘关系。结果表明微卫星标记不同位点间遗传多样性差异极显著 (P <0 0 1) ,群体间多态信息含量 (PIC)、近交程度 (Fis)和观察杂合度 (Obs .Het)差异不显著 ,但基因多样性 (genediversity)和期望杂合度 (Exp .Het)差异显著 (P <0 0 5 )。所研究的我国 6个地方绵羊品种与欧洲品种具有相似的遗传多样性 ,但具有较高的近交系数。个体和群体的聚类分析结果提示我国地方绵羊品种可能起源于两类祖先。群体间的聚类分析结果还表明 ,蒙古羊与乌珠穆沁羊分化不明显且具有较近的遗传亲缘关系 ,蒙古羊与藏绵羊间分化明显且具有较远的遗传亲缘关系。滩羊、阿勒泰羊以及藏绵羊间也具有较近的遗传亲缘关系。所研究的我国 6个地方绵羊品种的遗传分化 (Fst)与西班牙绵羊品种接近 。 | 李祥龙 巩元芳 张建文 刘铮铸 Allessio Valentini | 2004 | Acta Genetica Sinica2004，31，11： | 19 |
| 2 | More anxious than depressed:prevalence and correlates in a 15-nation study of anxiety disorders in people with type 2 diabetes mellitus显示文摘Background Anxiety disorder, one of the highly disabling, prevalent and common mental disorders, is known to be more prevalent in persons with type 2 diabetes mellitus (T2DM) than the general population, and the comorbid presence of anxiety disorders is known to have an impact on the diabetes outcome and the quality of life. However, the information on the type of anxiety disorder and its prevalence in persons with T2DM is limited. Aims To assess the prevalence and correlates of anxiety disorder in people with type 2 diabetes in different countries. Methods People aged 18-65 years with diabetes and treated in outpatient settings were recruited in 15 countries and underwent a psychiatric interview with the Mini-International Neuropsychiatric Interview. Demographic and medical record data were collected. Results A total of 3170 people with type 2 diabetes (56.2% women;with mean (SD) duration of diabetes 10.01 (7.0) years) participated. The overall prevalence of anxiety disorders in type 2 diabetic persons was 18%;however, 2.8% of the study population had more than one type of anxiety disorder. The most prevalent anxiety disorders were generalised anxiety disorder (8.1%) and panic disorder (5.1%). Female gender, presence of diabetic complications, longer duration of diabetes and poorer glycaemic control (HbA1c levels) were significantly associated with comorbid anxiety disorder. A higher prevalence of anxiety disorders was observed in Ukraine, Saudi Arabia and Argentina with a lower prevalence in Bangladesh and India. Conclusions Our international study shows that people with type 2 diabetes have a high prevalence of anxiety disorders, especially women, those with diabetic complications, those with a longer duration of diabetes and poorer glycaemic control. Early identification and appropriate timely care of psychiatric problems of people with type 2 diabetes is warranted. | Santosh K Chaturvedi Shayanth Manche Gowda Helal Uddin Ahmed Fahad D Alosaimi Nicola Andreone Alexey Bobrov Viola Bulgari Giuseppe Carra Gianluca Castelnuovo Giovanni de Girolamo Tomasz Gondek Nikola Jovanovic Thummala Kamala Andrzej Ki Nebojsa Lalic Dusica Lecic-Tosevski Fareed Minhas Victoria Mutiso David Ndetei Golam Rabbani Suntibenchakul Somruk Sathyanarayana Srikanta Rizwan Taj Umberto Valentini Olivera Vukovic Wolfgang Wolwer Larry Cimino Arie Nouwen Cathy Lloyd Norman Sartorius | 2019 | General Psychiatry2019，32，4： | 11 |
| 3 | 利用DHPLC研究我国几个地方绵羊品种黑素细胞刺激素受体基因单核苷酸多态性(英文)显示文摘利用测序及变性高效液相色谱 (DHPLC)研究了蒙古羊、哈萨克羊、滩羊和藏绵羊黑素细胞刺激素受体(MSHR)基因单核苷酸多态性 (SNP)。结果表明 ,在扩增片断长度为 4 15bp范围内存在一个T317C突变 ,DHPLC可检测到该突变并被证明是一种高通量且简便的筛选方法。通过两次DHPLC可确定两个杂合子和一个纯合子 ,第一次DHPLC可迅速检测出由于形成异源双链而呈肩峰的杂合子 (TC) ,但不能区分两个均呈单峰的纯合子 (TT或CC)。第二次DHPLC将未知纯合子与已知序列的纯合子混合后进行 ,通过判定单峰或肩峰即可推断未知纯合子的基因型。所研究的 4个绵羊群体在该突变位点均处于Hardy Weinberg平衡状态。 | 李祥龙 巩元芳 刘铮铸 张建文 Allessio Valentini | 2004 | 遗传2004，26，6： | 9 |
| 4 | Hepatorenal syndrome: Update on diagnosis and treatment显示文摘Acute kidney injury(AKI) is a common complication in patients with end-stage liver disease and advanced cirrhosis regardless of the underlying cause. Hepatorenal syndrome(HRS), a functional form of kidney failure, is one of the many possible causes of AKI. HRS is potentially reversible but involves highly complex pathogenetic mechanisms and equally complex clinical and therapeutic management. Once HRS has developed, it has a very poor prognosis. This review focuses on the diagnostic approach to HRS and discusses the therapeutic protocols currently adopted in clinical practice. | Olga Baraldi Chiara Valentini Gabriele Donati Giorgia Comai Vania Cuna Irene Capelli Maria Laura Angelini Maria Ilaria Moretti Andrea Angeletti Fabio Piscaglia Gaetano La Manna | 2015 | World Journal of Nephrology2015，4，5： | 5 |

| 6 | Effect of early propranolol administration on portal hypertensive gastropathy in cirrhotic rats显示文摘AIM:To investigate any protective effect of early propranolol administration in the development of portal hypertensive gastropathy in cirrhotic rats. METHODS:For the development of liver cirrhosis and portal hypertensive gastropathy,60 rats underwent ligation of the left adrenal vein and complete devascularization of the left renal vein,followed by phenobarbital and carbon tetrachloride(CCl4) administration.After two weeks of CCl4 administration, the rats were randomly separated into two groups.In group A,propranolol was continuously administered intragastrically throughout the study,whereas in group B normal saline(placebo)was administered instead. Hemodynamic studies and vascular morphometric analysis of gastric sections were performed after complete induction of cirrhosis. RESULTS:Vascular morphometric studies showed higher numbers of vessels in all mucosal layers in the control group.Statistical analysis revealed a significantly higher total vascular surface in the control group compared to the propranolol group,but with no statistically significant difference between the mean vascular surfaces between the groups.Our study clearly shows that the increased mucosal blood flow is manifested by a marked increase of vessel count. CONCLUSION:Early propranolol's administration in portal hypertensive cirrhotic rats seems to prevent intense gastric vascular congestion that characterizes portal hypertensive gastropathy. | Savas Rafailidis Charalampos Demertzidis Konstantinos Ballas Michail Alatsakis Nikolaos Symeonidis Theodoros Pavlidis Kyriakos Psarras Valentini Tzioufa-Asimakopoulou Athanassios Sakadamis | 2009 | World Journal of Gastroenterology2009，15，34： | 3 |
| 7 | Empirical estimates of regional carbon budgets imply reduced global soil heterotrophic respiration显示文摘Resolving regional carbon budgets is critical for informing land-based mitigation policy.For nine regions covering nearly the whole globe,we collected inventory estimates of carbon-stock changes complemented by satellite estimates of biomass changes where inventory data are missing.The net land–atmospheric carbon exchange(NEE)was calculated by taking the sum of the carbon-stock change and lateral carbon fluxes from crop and wood trade,and riverine-carbon export to the ocean.Summing up NEE from all regions,we obtained a global‘bottom-up'NEE for net land anthropogenic CO_(2)uptake of–2.2±0.6 Pg C yr^(-1)consistent with the independent top-down NEE from the global atmospheric carbon budget during 2000–2009.This estimate is so far the most comprehensive global bottom-up carbon budget accounting,which set up an important milestone for global carbon-cycle studies.By decomposing NEE into component fluxes,we found that global soil heterotrophic respiration amounts to a source of CO_(2)of 39 Pg C yr^(-1)with an interquartile of 33–46 Pg C yr^(-1)—a much smaller portion of net primary productivity than previously reported. | Philippe Ciais Yitong Yao Thomas Gasser Alessandro Baccini Yilong Wang Ronny Lauerwald Shushi Peng Ana Bastos Wei Li Peter A.Raymond Josep G.Canadell Glen P.Peters Rob J.Andres Jinfeng Chang Chao Yue A.Johannes Dolman Vanessa Haverd Jens Hartmann Goulven Laruelle Alexandra G.Konings Anthony W.King Yi Liu Sebastiaan Luyssaert Fabienne Maignan Prabir K.Patra Anna Peregon Pierre Regnier Julia Pongratz Benjamin Poulter Anatoly Shvidenko Riccardo Valentini Rong Wang Grégoire Broquet Yi Yin Jakob Zscheischler Bertrand Guenet Daniel SGoll Ashley-P.Ballantyne Hui Yang Chunjing Qiu Dan Zhu | 2021 | National Science Review2021，8，2： | 3 |
| 8 | Management of single pulmonary metastases from colorectal cancer:State of the art显示文摘Colorectal cancer(CRC)is one of the most common causes of death from cancer.Lung seeding occurs in approximately 10%of patients surgically treated for primary CRC with radical intent:the lung is the most common site of metastases after the liver.While surgical treatment of liver metastases is widely accepted to affect long-term outcomes,more controversial and not standardized is the therapy for CRC patients developing lung metastases.Experience suggests the potential curative role of pulmonary metastasectomy,especially in oligometastatic disease.However,the optimal strategy of care and the definition of prognostic factors after treatment still need to be defined.This review focused on the uncommon scenario of single pulmonary metastases from CRC.We explored pertinent literature and provide an overview of the epidemiology,clinical characteristics and imaging of single pulmonary metastases from CRC.Additionally,we identified the best available evidence for overall management.In particular,we analyzed the role and results of locoregional approaches(surgery,radiotherapy or ablative procedures)and their integration with systemic therapy. | Marco Chiappetta Lisa Salvatore Maria Teresa Congedo Maria Bensi Viola De Luca Leonardo PetraccaCiavarella Floriana Camarda Jessica Evangelista Vincenzo Valentini Giampaolo Tortora StefanoMargaritora Filippo Lococo | 2022 | World Journal of Gastrointestinal Oncology2022，14，4： | 2 |
| 9 | Orthostatic hypotension,an often-neglected problem in community-dwelling older people:discrepancies between studies and real life显示文摘Orthostatic hypotension (OH)is a common condition in older persons.According to the 2011criteria,OH is defined by a sustained reduction of systolic blood pressure of 20 mmHg or a 10mmHg-fall of diastolic blood pressure,[1] Its prevalence increases with age and according to a recent systematic review the pooled prevalence in community dwelling older people is 22.2%.[2]Although OH is largely explained by concurrent clinical conditions (in particular, hypertension,diabetes,malnutrition,vascular encephalopa- thy,anemia,Parkinson's disease)[3],aging per se determines a series of physiological dysfunctions potentially representing its biological substratum (e.g.,reduction in barore- flex-mediated cardiovascular function,altered salt and water balance at renal level,impaired cardiac diastolic filling).It is also noteworthy that age-related changes in pharmacokinetic and pharmacodynamic mechanisms of drugs (especially in the context of polypharmacy)also increase the risk of OH. | Sarah Damanti Dario Consormi Annalisa Valentini Benedetta Cerasoli Martina Biotto Federica Conti Marta Clerici Pasqualina Iannuzzi Emanuela Manzo Paolo D Rossi Simona Ciccone Matteo Cesari | 2018 | Journal of Geriatric Cardiology2018，15，10： | 2 |

| 11 | Hypofractionated and Low Dose Radiotherapy Combined with Temozolomide in Naive Unresectable Glioblastoma:A Pilot Study显示文摘Background/Aim: To assess safety of hypo-fractionated radiotherapy( HyRT) followed by low dose radiation therapy( LD-FRT) plus Temozolomide( TMZ) in naive unresectable Glioblastoma. Methods: Patients( ECOG < 2,age > 18) undergone to biopsy or with gross residual tumor after surgery were enrolled. HyRT( 30 Gy in ten fraction) plus TMZ was administered. From the second adjuvant cycle of TMZ,patients received LD-FRT( 0. 40 Gy twice daily over 5 days,every 28 days) for two cycles. The primary endpoints were safety and toxicity. Moreover we analyzed response,overall survival( OS) and progression-free survival( PFS). Results: Twenty patients were enrolled. Median dose of LD-FRT was 12 Gy. All toxicities were reversible. Four out of 20 patients had Partial Response( PR)and 6 experienced a stable disease( SD). Median OS and PFS were 14 and 11 months,respectively.Conclusions: HyRT followed by LD-FRT plus TMZ is safe and shows good clinical outcomes. A new study is ongoing. | Silvia Chiesa Milena Ferro Stefano Luzi Barbara Diletto Francesco Beghella Bartoli Nicola Dinapoli Gian Carlo Mattiucci Vincenzo Frascino Francesco Miccichè Cesare Colosimo Carmelo Anile Alessandro Olivi Vincenzo Valentini Mario Balducci | 2017 | 肿瘤预防与治疗2017，30，1： | 2 |
| 12 | Al_2O_3负载Cu,Fe或Ni掺杂氧化钼催化乙苯氧化脱氢(英文)显示文摘Molybdenum-based catalysts supported on Al_2O_3 doped with Ni, Cu, or Fe oxide were synthesized and used in ethylbenzene dehydrogenation to produce styrene. The molybdenum oxide was supported using an unconventional route that combined the polymeric precursor method(Pechini) and wet impregnation on commercial alumina. The samples were characterized by X-ray diffraction(XRD), N_2 adsorption-desorption isotherms, temperature-programmed reduction of H_2(H_2-TPR),and thermogravimetric(TG) analysis. XRD results showed that the added metals were well dispersed on the alumina support. The addition of the metal oxide(Ni, Cu, or Fe) of 2 wt% by wet impregnation did not affect the texture of the support. TPR results indicated a synergistic effect between the dopant and molybdenum oxide. The catalytic tests showed ethylbenzene conversion of 28%–53% and styrene selectivity of 94%–97%, indicating that the addition of the dopant improved the catalytic performance, which was related to the redox mechanism. Molybdenum oxides play a fundamental role in the oxidative dehydrogenation of ethylbenzene to styrene by its redox and acid–base properties. The sample containing Cu showed an atypical result with increasing conversion during the reaction, which was due to metal reduction. The Ni-containing solid exhibited the highest amount of carbon deposited, shown by TG analysis after the catalytic test, which explained its lower catalytic stability and selectivity. | Tiago Pinheiro Braga Ant?nio Narcísio Pinheiro Edson R.Leite Regina Cláudia R.dos Santos Antoninho Valentini | 2015 | 催化学报2015，36，5： | 2 |
