| 1 | Ecosystem carbon stocks and their changes in China's grasslands显示文摘The knowledge of carbon(C) stock and its dynamics is crucial for understanding the role of grassland ecosystems in China's terrestrial C cycle.To date,a comprehensive assessment on C balance in China's grasslands is still lacking.By reviewing published literature,this study aims to evaluate ecosystem C stocks(both vegetation biomass and soil organic C) and their changes in China's grasslands.Our results are summarized as follows:(1) biomass C density(C stock per area) of China's grasslands differed greatly among previous studies,ranging from 215.8 to 348.1 g C m-2 with an average of 300.2 g C m-2.Likewise,soil C density also varied greatly between 8.5 and 15.1 kg C m-2.In total,ecosystem C stock in China's grasslands was estimated at 29.1 Pg C.(2) Both the magnitude and direction of ecosystem C changes in China's grasslands differed greatly among previous studies.According to recent reports,neither biomass nor soil C stock in China's grasslands showed a significant change during the past 20 years,indicating that grassland ecosystems are C neutral.(3) Spatial patterns and temporal dynamics of grassland biomass were closely correlated with precipitation,while changes in soil C stocks exhibited close associations with soil moisture and soil texture.Human activities,such as livestock grazing and fencing could also affect ecosystem C dynamics in China's grasslands. | Anwar MOHAMMAT | 2010 | Science China(Life Sciences)2010，53，7： | 52 |
| 2 | Biomass carbon stocks and their changes in northern China's grasslands during 1982-2006显示文摘Grassland covers approximately one-third of the area of China and plays an important role in the global terrestrial carbon(C) cycle.However,little is known about biomass C stocks and dynamics in these grasslands.During 2001-2005,we conducted five consecutive field sampling campaigns to investigate above-and below-ground biomass for northern China's grasslands.Using measurements obtained from 341 sampling sites,together with a NDVI(normalized difference vegetation index) time series dataset over 1982-2006,we examined changes in biomass C stock during the past 25 years.Our results showed that biomass C stock in northern China's grasslands was estimated at 557.5 Tg C(1 Tg=1012 g),with a mean density of 39.5 g C m-2 for above-ground biomass and 244.6 g C m-2 for below-ground biomass.An increasing rate of 0.2 Tg C yr-1 has been observed over the past 25 years,but grassland biomass has not experienced a significant change since the late 1980s.Seasonal rainfall(January-July) was the dominant factor driving temporal dynamics in biomass C stock;however,the responses of grassland biomass to climate variables differed among various grassland types.Biomass in arid grasslands(i.e.,desert steppe and typical steppe) was significantly associated with precipitation,while biomass in humid grasslands(i.e.,alpine meadow) was positively correlated with mean January-July temperatures.These results suggest that different grassland ecosystems in China may show diverse responses to future climate changes. | Anwar MOHAMMAT | 2010 | Science China(Life Sciences)2010，53，7： | 60 |
| 3 | 慢性乙型肝炎患者肝脏良性占位的发病率及其特点:基于39450例彩色多普勒超声的病例对照研究显示文摘目的调查慢性乙型肝炎(CHB)患者中肝脏良性占位性病变的发病率,以普通人群为对照,分析其高发的风险因素及其与小肝癌的鉴别要点。方法回顾性分析2016年1月~2017年12月于南方医院肝脏中心就诊的17 721例CHB患者的影像学资料及相关临床资料,与同期在南方医院健康管理中心行常规体检的21629例普通人群进行比较分析。结果与普通人群相比,CHB患者的肝囊肿、肝血管瘤、肝硬化结节发病率更高,局灶性结节性增生的发病率更低(分别为11.8%vs 8.7%、8.2%vs 1.6%、20.6%vs 2.4%、0.006%vs 0.042%,均P<0.05),肝细胞腺瘤的发病率无统计学差异(P>0.05)。肝囊肿和肝硬化结节的发病率随年龄增长而升高,其中男性发病率高于女性(P<0.001);肝血管瘤的发病率在30~49岁患者中最高,无性别差异(P>0.05)。肝脏良性占位的超声表现多为内部回声均匀,边界清晰,形态规则:肝血管瘤常为高回声(83.32%,1579/1895),与小肝癌相比,它的四周与内部血流信号较少,固有动脉流速更低,门静脉流速更高;肝硬化结节多为强、弱混合回声(79.60%,7637/9595),结节内部和周边无血流信号,当其体积增大,伴内部回声发生不均匀改变时,提示恶变概率升高;肝囊肿常表现为内部无回声,后方回声增强。结论CHB患者较普通人群更易发生肝囊肿、肝血管瘤和肝硬化结节;其发病率与年龄、性别相关。本研究总结的肝脏良、恶性占位,特别是肝硬化结节的超声声学和血流学特征,能够为早期识别肝脏占位的性质提供重要线索和依据。 | 任彦瑜 袁国盛 周宇辰 胡承光 刘俊维 Muhammad Ikram ANWAR 唐淬蓉 李园 于文轩 周元平 戴琳 | 2019 | 南方医科大学学报2019，39，10： | 25 |
| 4 | Clinical outcomes of isolated renal failure compared to other forms of organ failure in patients with severe acute pancreatitis显示文摘AIM To assess differences in clinical outcomes of isolated renal failure(RF) compared to other forms of organ failure(OF) in patients with severe acute pancreatitis(SAP).METHODS Using a prospectively maintained database of patients with acute pancreatitis admitted to a tertiary medical center between 2003 and 2016, those with evidence of persistent OF were classified to renal, respiratory, cardiovascular, or multi-organ(2 or more organs). Data regarding demographics, comorbidities, etiology of acute pancreatitis, and clinical outcomes were prospectively recorded. Differences in clinical outcomes after development of isolated RF in comparison to other forms of OF were determined using independent t and Mann-Whitney U tests for continues variables, and χ~2 test for discrete variables.RESULTS Among 500 patients with acute pancreatitis, 111 patients developed persistent OF: mean age was 54 years, and 75(67.6%) were male. Forty-three patients had isolated OF: 17(15.3%) renal, 25(21.6%) respiratory, and 1(0.9%) patient with cardiovascular failure. No differences in demographics, etiology of acute pancreatitis, systemic inflammatory response syndrome scores, or development of pancreatic necrosis were seen between patients with isolated RF vs isolated respiratory failure. Patients with isolated RF were less likely to require nutritional support(76.5% vs 96%, P = 0.001), ICU admission(58.8% vs 100%, P = 0.001), and had shorter mean ICU stay(2.4 d vs 15.7 d, P < 0.001), compared to isolated respiratory failure. None of the patients with isolated RF or isolated respiratory failure died.CONCLUSION Among patients with SAP per the Revised Atlanta Classification, approximately 15% develop isolated RF. This subgroup seems to have a less protracted clinical course compared to other forms of OF. Isolated RF might be weighed less than isolated respiratory failure in risk predictive modeling of acute pancreatitis. | Amir Gougol Mohannad Dugum Anwar Dudekula Phil Greer Adam Slivka David C Whitcomb Dhiraj Yadav Georgios I Papachristou | 2017 | World Journal of Gastroenterology2017，23，29： | 20 |
| 5 | Essential oils used in aromatherapy: A systemic review显示文摘Nowadays, use of alternative and complementary therapies with mainstream medicine has gained the momentum. Aromatherapy is one of the complementary therapies which use essential oils as the major therapeutic agents to treat several diseases. The essential or volatile oils are extracted from the flowers, barks, stem, leaves, roots, fruits and other parts of the plant by various methods. It came into existence after the scientists deciphered the antiseptic and skin permeability properties of essential oils. Inhalation, local application and baths are the major methods used in aromatherapy that utilize these oils to penetrate the human skin surface with marked aura. Once the oils are in the system, they remodulate themselves and work in a friendly manner at the site of malfunction or at the affected area. This type of therapy utilizes various permutation and combinations to get relief from numerous ailments like depression, indigestion, headache, insomnia, muscular pain, respiratory problems, skin ailments, swollen joints, urine associated complications etc. The essential oils are found to be more beneficial when other aspects of life and diet are given due consideration. This review explores the information available in the literature regarding therapeutic, medical, cosmetic, psychological, olfactory, massage aromatherapy, safety issues and different plants used in aromatherapy. All the available information was compiled from electronic databases such as Academic Journals, Ethnobotany, Google Scholar, PubM ed, Science Direct, Web of Science, and library search. | Babar Ali Naser Ali Al-Wabel Saiba Shams Aftab Ahamad Shah Alam Khan Firoz Anwar | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，8： | 20 |
| 6 | Validation of a serum microRNA panel as biomarkers for early diagnosis of hepatocellular carcinoma post-hepatitis C infection in Egyptian patients显示文摘AIM To investigate the prospective importance of serum micro(mi)RNAs(mi R-125 b, mi R-138 b, mi R-1269, mi R-214-5p, mi R-494, mi R375 and mi R-145) as early biomarkers for the diagnosis of hepatitis C virus(HCV)-related hepatocellular carcinoma(HCC).METHODS Two-hundred and fifty HCV4 a patients, 224 HCV4 aHCC patients, and 84 healthy controls were enrolled in the study. Expression levels of mi R214-5p, mi R-125 b, mi R-1269 and mi R-375 were quantified using quantitative real-time PCR.RESULTS Expression of the selected mi RNAs in serum wassignificantly lower in HCC patients than in the healthy controls, except for mi R-1269 and mi R-494. There was a significant difference between HCC and HCV patients, in particular for HCC and late stage fibrosis, rather than HCV patients and early fibrosis. It is obvious that mi R-1269 was significantly upregulated in HCC cases compared to hepatic fibrosis cases. Each mi RNA can show HCC progression. Multivariate logistic regression analysis indicated that the tested panel of mi RNAs(mi R214-5p, mi R-125 b, mi R-1269 and mi R-375) represent accurate and specific indictors of HCC development.CONCLUSION This study presents a panel of mi RNAs with strong power as putative diagnostic and prognostic biomarkers for HCV-induced HCC. Moreover, mi R-214-5p and mi R-1269 could be considered as early biomarkers for tracking the progress of liver fibrosis to HCC. | Moustafa Nouh Elemeery Ahmed Noah Badr Marwa Anwar Mohamed Doaa Ahmed Ghareeb | 2017 | World Journal of Gastroenterology2017，23，21： | 20 |

| 8 | Ampullary carcinoma:Effect of preoperative biliary drainage on surgical outcome显示文摘AIM: To evaluate the influence of preoperative biliary drainage on morbidity and mortality after surgical resection for ampullary carcinoma. METHODS: We analyzed retrospectively data for 82 patients who underwent potentially curative surgery for ampullary carcinoma between September 1993 and July 2007 at the Singapore General Hospital, a tertiary referral hospital. Diagnosis of ampullary carcinoma was confirmed histologically. Thirty-five patients underwent preoperative biliary drainage (PBD group), and 47 were not drained (non-PBD group). The mode of biliary drainage was endoscopic retrograde cholangiopancreatography (n = 33) or percutaneous biliary drainage (n = 2). The following parameters were analyzed: wound infection, intra-abdominal abscess, intra-abdominal or gastrointestinal bleeding, septicemia, biliary or pancreatic leakage, pancreatitis, gastroparesis, and re-operation rate. Mortality was assessed at 30 d (hospital mortality) and also longterm. The statistical endpoint of this study was patient survival after surgery. RESULTS: The groups were well matched for demographic criteria, clinical presentation and operative characteristics, except for lower hemoglobin in the non-PBD group (10.9 ± 1.6 vs 11.8 ± 1.6 in the PBD group).Of the parameters assessing postoperative morbidity, incidence of wound infection was signif icantly less in the PBD than the non-PBD group [1 (2.9%) vs 12 (25.5%)]. However, the rest of the parameters did not differ signif icantly between the groups, i.e. sepsis [10 (28.6%) vs 14 (29.8%)], intra-abdominal bleeding [1 (2.9%) vs 5 (10.6%)], intra-abdominal abscess [1 (2.9%) vs 8 (17%)], gastrointestinal bleeding [3 (8.6%) vs 5 (10.6%)], pancreatic leakage [2 (5.7%) vs 3 (6.4%)], biliary leakage [2 (5.7%) vs 3 (6.4%)], pancreatitis [2 (5.7%) vs 2 (4.3%)], gastroparesis [6 (17.1%) vs 10 (21.3%)], need for blood transfusion [10 (28.6%) vs 17 (36.2%)] and re-operation rate [1 (2.9%) vs 5 (10.6%)]. There was no early mortality in either group. Median survival was 44 mo (95% CI: 34.2-53.8) in the PBD group and 41 mo (95% CI: 27.7-54.3; P = 0.86) in the non-PBD group. CONCLUSION: Biliary drainage before surgery for ampullary cancer significantly reduced postoperative wound infection. Overall mortality was not influenced by preoperative drainage. | Sheikh Anwar Abdullah Tarun Gupta Khairul Azhar Jaafar Yaw Fui Alexander Chung London Lucien Peng Jin Ooi Steven Joseph Mesenas | 2009 | World Journal of Gastroenterology2009，15，23： | 16 |
| 9 | Prognostic value of site-specific metastases in pancreatic adenocarcinoma: A Surveillance Epidemiology and End Results database analysis显示文摘AIM To evaluate the prognostic value of site-specific metastases among patients with metastatic pancreaticc arcinoma registered within the Surveillance, Epidemiology and End Results(SEER) database.METHODS SEER database(2010-2013) has been queried through SEER*Stat program to determine the presentation, treatment outcomes and prognostic outcomes of metastatic pancreatic adenocarcinoma according to the site of metastasis. In this study, metastatic pancreatic adenocarcinoma patients were classified according to the site of metastases(liver, lung, bone, brain and distant lymph nodes). We utilized chi-square test to compare the clinicopathological characteristics among different sites of metastases. We used Kaplan-Meier analysis and log-rank testing for survival comparisons. We employed Cox proportional model to perform multivariate analyses of the patient population; and accordingly hazard ratios with corresponding 95%CI were generated. Statistical significance was considered if a two-tailed P value < 0.05 was achieved. RESULTS A total of 13233 patients with stage Ⅳ pancreatic cancer and known sites of distant metastases were identified in the period from 2010-2013 and they were included into the current analysis. Patients with isolated distant nodal involvement or lung metastases have better overall and pancreatic cancer-specific survival compared to patients with isolated liver metastases(for overall survival: lung vs liver metastases: P < 0.0001; distant nodal vs liver metastases: P < 0.0001)(for pancreatic cancer-specific survival: lung vs liver metastases: P < 0.0001; distant nodal vs liver metastases: P < 0.0001). Multivariate analysis revealed that age < 65 years, white race, being married, female gender; surgery to the primary tumor and surgery to the metastatic disease were associated with better overall survival and pancreatic cancer-specific survival.CONCLUSION Pancreatic adenocarcinoma patients with isolated liver metastases have worse outcomes compared to patients with isolated lung or distant nodal metastases. Further research is needed to identify the highly selected subset of patients who may benefit from local treatment of the primary tumor and/or metastatic disease. | Hani Oweira Ulf Petrausch Daniel Helbling Jan Schmidt Meinrad Mannhart Arianeb Mehrabi Othmar Schob Anwar Giryes Michael Decker Omar Abdel-Rahman | 2017 | World Journal of Gastroenterology2017，23，10： | 13 |
| 10 | DNA methylation,microRNAs,and their crosstalk as potential biomarkers in hepatocellular carcinoma显示文摘Epigenetic alterations have been identified as a major characteristic in human cancers.Advances in the field of epigenetics have contributed significantly in refining our knowledge of molecular mechanisms underlying malignant transformation.DNA methylation and microRNA expression are epigenetic mechanisms that are widely altered in human cancers including hepatocellular carcinoma(HCC),the third leading cause of cancer related mortality worldwide.Both DNA methylation and microRNA expression patterns are regulated in developmental stage specific-,cell type specific-and tissue-specific manner.The aberrations are inferred in the maintenance of cancer stem cells and in clonal cell evolution during carcinogenesis.The availability of genome-wide technologies for DNA methylation and microRNA profiling has revolutionized the field of epigenetics and led to the discovery of a number of epigenetically silenced microRNAs in cancerous cells and primary tissues.Dysregulation of these microRNAs affects several key signalling pathways in hepatocarcinogenesis suggesting that modulation of DNA methylation and/or microRNA expression can serve as new therapeutic targets for HCC.Accumulative evidence shows that aberrant DNA methylation of certain microRNA genes is an event specifically found in HCC which correlates with unfavorable outcomes.Therefore,it can potentially serve as a biomarker for detection as well as for prognosis,monitoring and predicting therapeutic responses in HCC. | Sumadi Lukman Anwar Ulrich Lehmann | 2014 | World Journal of Gastroenterology2014，20，24： | 11 |

| 14 | Low skeletal muscle mass is associated with non-alcoholic fatty liver disease in Korean adults: the Fifth Korea National Health and Nutrition Examination Survey显示文摘BACKGROUND: Sarcopenia and non-alcoholic fatty liver disease(NAFLD) share similar pathophysiological mechanisms, and the relationship between sarcopenia and NAFLD has been recently investigated. The study investigated whether low skeletal muscle mass is differentially associated with NAFLD by gender in Korean adults.METHODS: We conducted a cross-sectional analysis of the data from the Fifth Korea National Health and Nutrition Examination Survey. The skeletal muscle index(SMI) was obtained by the appendicular skeletal muscle mass divided by the weight. NAFLD was defined as a fatty liver index(FLI) ≥60 in the absence of other chronic liver disease.RESULTS: Among the included subjects, 18.3%(SE: 1.4%) in men and 7.0%(SE: 0.7%) in women were classified as having FLI-defined NAFLD. Most of the risk factors for FLI-defined NAFLD showed a significant negative correlation with the SMI in both genders. Multiple logistic regression analysis showed that low SMI was associated with FLI-defined NAFLD, independent of other metabolic and lifestyle parameters in both genders [males: odds ratio(OR)=1.35; 95% confidence interval(CI): 1.17-1.54; females: OR=1.36; 95% CI: 1.18-1.55]. The magnitude of the association between FLI-defined NAFLD and low SMI was higher in middle aged to elderly males(OR=1.50; 95% CI: 1.22-1.84) than in males less than 45 years of age(OR=1.25; 95% CI: 1.02-1.52) and in premenopausal females(OR=1.50; 95% CI: 1.12-2.03) than in postmenopausal females(OR=1.36; 95% CI: 1.20-1.54).CONCLUSIONS: Low SMI is associated with the risk of FLIdefined NAFLD independent of other well-known metabolic risk factors in both genders. This association may differ according to age group or menopausal status. Further studies are warranted to confirm this relationship. | hee yeon kim chang wook kim chung-hwa park jong young choi kyungdo han anwar t merchant yong-moon park | 2016 | Hepatobiliary & Pancreatic Diseases International2016，15，1： | 7 |

| 17 | Three Tier Fog Networks: Enabling IoT/5G for Latency Sensitive Applications显示文摘Following the progression in Internet of Things(IoT) and 5G communication networks, the traditional cloud computing model have shifted to fog computing. Fog computing provides mobile computing, network control and storage to the network edges to assist latency critical and computation-intensive applications. Moreover, security features are improved in fog paradigm by processing critical data on edge devices instead of data centres outside the control plane of users. However, fog network deployment imposes many challenges including resource allocation, privacy of users, non-availability of programming model and testing software and support for the heterogenous networks. This article highlights these challenges and their potential solutions in detail. This article also discusses threetier fog network architecture, its standardization and benefits in detail. The proposed resource allocation mechanism for three tier fog networks based on swap matching is described. Results show that by practicing the proposed resource allocation mechanism, maximum throughput with reduced latency is achieved. | Romana Shahzadi Ambreen Niaz Mudassar Ali Muhammad Naeem Joel J.P.C.Rodrigues Farhan Qamar Syed Muhammad Anwar | 2019 | China Communications2019，16，3： | 6 |
