4Serum Uric Acid is Associated with the Predicted Risk of Prevalent Cardiovascular Disease in a Community-dwelling Population without Diabetes显示文摘Objective To examine the association between serum uric acid levels and cardiovascular disease risk among individuals without diabetes. Methods We investigated the association between serum uric acid levels and the risk of prevalent cardiometabolic diseases, 10-year Framingham risk for coronary heart disease, and 10-year risk for atherosclerotic cardiovascular diseases(ASCVD) among 8,252 participants aged ≥ 40 years without diabetes from Jiading district, Shanghai, China. Results Body mass index, waist circumference, blood glucose, glycated hemoglobin, blood pressure, and serum lipids increased progressively across the sex-specific quartiles of uric acid(all P trend < 0.05). Compared with individuals in the lowest quartile, those in the higher quartiles had a significantly higher prevalence of obesity, hypertension, and dyslipidemia(all P trend < 0.05). A fully adjusted logistic regression analysis revealed that individuals in the highest quartile had an increased risk of predicted cardiovascular disease compared with those in the lowest quartile of uric acid. The multivariate adjusted odds ratios(ORs) [95% confidence intervals(CIs)] for the highest quartiles for high Framingham risk were 3.00(2.00-4.50) in men and 2.95(1.08-8.43) in women. The multivariate adjusted ORs(95% CIs) for the highest quartile for high ASCVD risk were 1.93(1.17-3.17) in men and 4.53(2.57-7.98) in women. Conclusion Serum uric acid level is associated with an increased risk of prevalent obesity, hypertension, dyslipidemia, 10-year Framingham risk for coronary heart disease, and 10-year risk for ASCVD among Chinese adults without diabetes.CHENG Di DU Rui WU Xue Yan LIN Lin PENG Kui MA Li Na XU Yu XU Min CHEN Yu Hong BI Yu Fang WANG Wei Qing DAI Meng LU Jie Li 2018Biomedical and Environmental Sciences2018,31,2:13
5Management of granulomatous lobular mastitis: an international multidisciplinary consensus(2021 edition)显示文摘Granulomatous lobular mastitis(GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence.Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions,etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology.The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidencebased consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM.Qian-Qian Yuan Shu-Yuan Xiao Omar Farouk Yu-Tang Du Fereshte Sheybani Qing Ting Tan Sami Akbulut Kenan Cetin Afsaneh Alikhassi Rami Jalal Yaghan Irmak Durur-Subasi Fatih Altintoprak Tae Ik Eom Fatih Alper Mustafa Hasbahceci David Martínez-Ramos Pelin Seher Oztekin Ava Kwong Cedric W.Pluguez-Turul Kirstyn EBrownson Shirish Chandanwale Mehran Habib Liu-Yi Lan Rui Zhou Xian-Tao Zeng Jiao Bai Jun-Wen Bai Qiong-Rong Chen Xing Chen Xiao-Ming Zha Wen-Jie Dai Zhi-Jun Dai Qin-Yu Feng Qing-Jun Gao Run-Fang Gao Bao-San Han Jin-Xuan Hou Wei Hou Hai-Ying Liao Hong Luo Zheng-Ren Liu Jing-Hua Lu Bin Luo Xiao-Peng Ma Jun Qian Jian-Yong Qin Wei Wei Gang Wei Li-Ying Xu Hui-Chao Xue Hua-Wei Yang Wei-Ge Yang Chao-Jie Zhang Fan Zhang Guan-Xin Zhang Shao-Kun Zhang Shu-Qun Zhang Ye-Qiang Zhang Yue-Peng Zhang Sheng-Chu Zhang Dai-Wei Zhao Xiang-Min Zheng Le-Wei Zheng Gao-Ran Xu Wen-Bo Zhou Gao-Song Wu 2022Military Medical Research2022,9,4:13
6Carbon pools and fluxes in the China Seas and adjacent oceans显示文摘The China Seas include the South China Sea, East China Sea, Yellow Sea, and Bohai Sea. Located off the Northwestern Pacific margin, covering 4700000 km^2 from tropical to northern temperate zones, and including a variety of continental margins/basins and depths, the China Seas provide typical cases for carbon budget studies. The South China Sea being a deep basin and part of the Western Pacific Warm Pool is characterized by oceanic features; the East China Sea with a wide continental shelf, enormous terrestrial discharges and open margins to the West Pacific, is featured by strong cross-shelf materials transport; the Yellow Sea is featured by the confluence of cold and warm waters; and the Bohai Sea is a shallow semiclosed gulf with strong impacts of human activities. Three large rivers, the Yangtze River, Yellow River, and Pearl River, flow into the East China Sea, the Bohai Sea, and the South China Sea, respectively. The Kuroshio Current at the outer margin of the Chinese continental shelf is one of the two major western boundary currents of the world oceans and its strength and position directly affect the regional climate of China. These characteristics make the China Seas a typical case of marginal seas to study carbon storage and fluxes. This paper systematically analyzes the literature data on the carbon pools and fluxes of the Bohai Sea,Yellow Sea, East China Sea, and South China Sea, including different interfaces(land-sea, sea-air, sediment-water, and marginal sea-open ocean) and different ecosystems(mangroves, wetland, seagrass beds, macroalgae mariculture, coral reefs, euphotic zones, and water column). Among the four seas, the Bohai Sea and South China Sea are acting as CO_2 sources, releasing about0.22 and 13.86–33.60 Tg C yr^(-1) into the atmosphere, respectively, whereas the Yellow Sea and East China Sea are acting as carbon sinks, absorbing about 1.15 and 6.92–23.30 Tg C yr^(-1) of atmospheric CO_2, respectively. Overall, if only the CO_2 exchange at the sea-air interface is considered, the Chinese marginal seas appear to be a source of atmospheric CO_2, with a net release of 6.01–9.33 Tg C yr^(-1), mainly from the inputs of rivers and adjacent oceans. The riverine dissolved inorganic carbon (DIC) input into the Bohai Sea and Yellow Sea, East China Sea, and South China Sea are 5.04, 14.60, and 40.14 Tg C yr^(-1),respectively. The DIC input from adjacent oceans is as high as 144.81 Tg C yr^(-1), significantly exceeding the carbon released from the seas to the atmosphere. In terms of output, the depositional fluxes of organic carbon in the Bohai Sea, Yellow Sea, East China Sea, and South China Sea are 2.00, 3.60, 7.40, and 5.92 Tg C yr^(-1), respectively. The fluxes of organic carbon from the East China Sea and South China Sea to the adjacent oceans are 15.25–36.70 and 43.93 Tg C yr^(-1), respectively. The annual carbon storage of mangroves, wetlands, and seagrass in Chinese coastal waters is 0.36–1.75 Tg C yr^(-1), with a dissolved organic carbon(DOC) output from seagrass beds of up to 0.59 Tg C yr^(-1). Removable organic carbon flux by Chinese macroalgae mariculture account for 0.68 Tg C yr^(-1) and the associated POC depositional and DOC releasing fluxes are 0.14 and 0.82 Tg C yr^(-1), respectively. Thus, in total, the annual output of organic carbon, which is mainly DOC, in the China Seas is 81.72–104.56 Tg C yr^(-1). The DOC efflux from the East China Sea to the adjacent oceans is 15.00–35.00 Tg C yr^(-1). The DOC efflux from the South China Sea is 31.39 Tg C yr^(-1). Although the marginal China Seas seem to be a source of atmospheric CO_2 based on the CO_2 flux at the sea-air interface, the combined effects of the riverine input in the area, oceanic input, depositional export,and microbial carbon pump(DOC conversion and output) indicate that the China Seas represent an important carbon storage area.Nianzhi JIAO Yantao LIANG Yongyu ZHANG Jihua LIU Yao ZHANG Rui ZHANG Meixun ZHAO Minhan DAI Weidong ZHAI Kunshan GAO Jinming SONG Dongliang YUAN Chao LI Guanghui LIN Xiaoping HUANG Hongqiang YAN Limin HU Zenghu ZHANG Long WANG Chunjie CAO Yawei LUO Tingwei LUO Nannan WANG Hongyue DANG Dongxiao WANG Si ZHANG 2018Science China Earth Sciences2018,61,11:12
7Therapeutic effect of neohesperidin on TNF-α-stimulated human rheumatoid arthritis fibroblast-like synoviocytes显示文摘During the pathogensis of rheumatoid arthritis(RA),activated RA fibroblast-like synoviocytes(RA-FLSs)combines similar proliferative features as tumor and inflammatory features as osteoarthritis,which eventually leads to joint erosion.Therefore,it is imperative to research and develop new compounds,which can effectively inhibit abnormal activation of RA-FLSs and retard RA progression.Neohesperidin(Neo)is a major active component of flavonoid compounds with anti-inflammation and anti-oxidant properties.In this study,the anti-inflammation,anti-migration,anti-invasion,anti-oxidant and apoptosis-induced effects of Neo on RAFLSs were explored to investigate the underlying mechanism.The results suggested that Neo decreased the levels of interleukin IL-1β,IL-6,IL-8,TNF-α,MMP-3,MMP-9 and MMP-13 in FLSs.Moreover,Neo blocked the activation of the MAPK signaling pathway.Furthermore,treatment with Neo induced the apoptosis of FLSs,and inhibited the migration of FLSs.It was also found that Neo reduced the accumulation of reactive oxygen species(ROS)induced by TNF-α.Taken together,our results highlighted that Neo may act as a potential and promising therapeutic drug for the management of RA.WANG Xiao-He DAI Ce WANG Jun LIU Rui LI Lei YIN Zong-Sheng 2021Chinese Journal of Natural Medicines2021,19,10:10
8Chromosome-Level Reference Genome and Population Genomic Analysis Provide Insights into the Evolution and Improvement of Domesticated Mulberry (Morns alba)显示文摘Mulberry(Morns spp.)is the sole plant consumed by the domesticated silkworm.However,the genome of domesticated mulberry has not yet been sequenced,and the ploidy level of this species remains unclear.Here,we report a high-quality,chromosome-level domesticated mulberry(Morus alba)genome.Analysis of genomic data and karyotype analyses confirmed that M.alba is a diploid with 28 chromosomes(2/7=2x=28).Population genomic analysis based on resequencing of 134 mulberry accessions classified domesticated mulberry into three geographical groups,namely,Taihu Basin of southeastern China(Hu mulberry),northern and southwestern China,and Japan.Hu mulberry had the lowest nucleotide diversity among these accessions and demonstrated obvious signatures of selection associated with environmental adaptation.Further phylogenetic analysis supports a previous proposal that multiple domesticated mulberry accessions previously classified as different species actually belong to one species.This study expands our understanding of genome evolution of the genus Morus and population structure of domesticated mulberry,which would facilitate mulberry breeding and improvement.Feng Jiao Rongsong Luo Xuelei Dai Hui Liu Gang Yu Shuhua Han Xin Lu Chao Su Qi Chen Qinxia Song Caiting Meng Fanghong Li Hongmei Sun Rui Zhang Tian Hui Yonghua Qian Aichun Zhao Yu Jiang 2020Molecular Plant2020,13,7:10
9Investigation on a vertical radial flow adsorber designed by a novel parallel connection method显示文摘Due to the increasing global demand for industrial gas, the development of large-scale cryogenic air separation systems has attracted considerable attention in recent years. Increasing the height of the adsorption bed in a vertical radial flow adsorber used in cryogenic air separation systems may efficiently increase the treatment capacity of the air in the adsorber. However, uniformity of the flow distribution of the air inside the adsorber would be deteriorated using the height-increasing method. In order to reduce the non-uniformity of the flow distribution caused by the excessive height of adsorption bed in a vertical radial flow adsorber, a novel parallel connection method is proposed in the present work. The experimental apparatus is designed and constructed; the Computational Fluid Dynamics(CFD) technique is used to develop a CFD-based model, which is used to analyze the flow distribution, the static pressure drop and the radial velocity in the newly designed adsorber. In addition, the geometric parameters of annular flow channels and the adsorption bed thickness of the upper unit in the parallelconnected vertical radial flow adsorber are optimized, so that the upper and lower adsorption units could be penetrated by air simultaneously. Comparisons are made between the height-increasing method and the parallel connection method with the same adsorber height. It is shown that using the parallel connection method could reduce the difference between the maximum and minimum radial static pressure drop by 86.2% and improve the uniformity by 80% compared with those of using the height-increasing method. The optimal thickness ratio of the upper and lower adsorption units is obtained as 0.966, in which case the upper and lower adsorption units could be penetrated by air simultaneously, so that the adsorbents in adsorption space could be used more efficiently.Zhengshu Dai Meng Yu Daozhe Rui Xuejun Zhang Yang Zhao 2018Chinese Journal of Chemical Engineering2018,26,3:9

12Effects of acute kidney injury on acute pancreatitis patients’ survival rate in intensive care unit: A retrospective study显示文摘BACKGROUND Acute kidney injury(AKI)is one of the most common acute pancreatitis(AP)-associated complications that has a significant effect on AP,but the factors affecting the AP patients’survival rate remains unclear.AIM To assess the influences of AKI on the survival rate in AP patients.METHODS A total of 139 AP patients were included in this retrospective study.Patients were divided into AKI group(n=72)and non-AKI group(n=67)according to the occurrence of AKI.Data were collected from medical records of hospitalized patients.Then,these data were compared between the two groups and further analysis was performed.RESULTS AKI is more likely to occur in male AP patients(P=0.009).AP patients in AKI group exhibited a significantly higher acute physiologic assessment and chronic health evaluation II score,higher Sequential Organ Failure Assessment score,lower Glasgow Coma Scale score,and higher demand for mechanical ventilation,infusion of vasopressors,and renal replacement therapy than AP patients in non-AKI group(P<0.01,P<0.01,P=0.01,P=0.001,P<0.01,P<0.01,respectively).Significant differences were noted in dose of norepinephrine and adrenaline,duration of mechanical ventilation,maximum and mean values of intra-peritoneal pressure(IPP),maximum and mean values of procalcitonin,maximum and mean serum levels of creatinine,minimum platelet count,and length of hospitalization.Among AP patients with AKI,the survival rate of surgical intensive care unit and in-hospital were only 23%and 21%of the corresponding rates in AP patients without AKI,respectively.The factors that influenced the AP patients’survival rate included body mass index(BMI),mean values of IPP,minimum platelet count,and hospital day,of which mean values of IPP showed the greatest impact.CONCLUSION AP patients with AKI had a lower survival rate and worse relevant clinical outcomes than AP patients without AKI,which necessitates further attention to AP patients with AKI in surgical intensive care unit.Ni Shi Guo-Dong Sun Yuan-Yuan Ji Ying Wang Yu-Cheng Zhu Wan-Qiu Xie Na-Na Li Qiu-Yuan Han Zhi-Dong Qi Rui Huang Ming Li Zhen-Yu Yang Jun-Bo Zheng Xing Zhang Qing-Qing Dai Gui-Ying Hou Yan-Song Liu Hong-Liang Wang Yang Gao 2021World Journal of Gastroenterology2021,27,38:8
13Effects of closing and reopening live poultry markets on the epidemic of human infection with avian influenza A virus显示文摘Live poultry markets(LPMs) are crucial places for human infection of influenza A(H7N9 virus).In Yangtze River Delta,LPMs were closed after the outbreak of human infection with avian influenza A(H7N9) virus,and then reopened when no case was found.Our purpose was to quantify the effect of LPMs' operations in this region on the transmission of influenza A(H7N9) virus.We obtained information about dates of symptom onset and locations for all human influenza A(H7N9) cases reported from Shanghai,Jiangsu and Zhejiang provinces by May 31,2014,and acquired dates of closures and reopening of LPMs from official media.A two-phase Bayesian model was fitted by Markov Chain Monte Carlo methods to process the spatial and temporal influence of human cases.A total of 235 cases of influenza A(H7N9) were confirmed in Shanghai,Jiangsu and Zhejiang by May 31,2014.Using these data,our analysis showed that,after LPM closures,the influenza A(H7N9) outbreak disappeared within two weeks in Shanghai,one week in Jiangsu,and one week in Zhejiang,respectively.Local authorities reopened LPMs when there was no outbreak of influenza A(H7N9),which did not lead to reemergence of human influenza A(H7N9).LPM closures were effective in controlling the H7N9 outbreak.Reopening of LPM in summer did not increase the risk of human infection with H7N9.Our findings showed that LPMs should be closed immediately in areas where the H7N9 virus is confirmed in LPM.When there is no outbreak of H7N9 virus,LPMs can be reopened to satisfy the Chinese traditional culture of buying live poultry.In the long term,local authorities should take a cautious attitude in permanent LPM closure.Jian Lu Wendong Liu Rui Xia Qigang Dai Changjun Bao Fenyang Tang Yefei Zhu Qiao Wang 2016The Journal of Biomedical Research2016,30,2:7
14Adsorption of rare earth ions using carbonized polydopamine nano carbon shells显示文摘Herein we reported the structure effects of carbon nano-shells prepared by the carbonization of polydopamine for the adsorption of rare earth elements(REEs) for the first time. Solid carbon spheres, 60 nm carbon shells and 500 nm carbon shells were prepared and evaluated for adsorption and desorption of REEs. The adsorption performance of carbon nano-shells for REEs was far superior to the solid carbon spheres. In addition, the effect of acidity on the adsorption and desorption properties was discussed. The good adsorption performance of the carbon nano-shells could be attributed to their pore structure, specific surface area, and the presence of both amine and carbonyl groups from the grafted dopamine.孙晓琦 LUO Huimin Shannon M.Mahurin LIU Rui HOU Xisen DAI Sheng 2016Journal of Rare Earths2016,34,1:6

16Lysyl oxidase and hypoxia-inducible factor 1α: biomarkers of gastric cancer显示文摘BACKGROUND Gastric cancer(GC) is one of the main causes of cancer mortality worldwide.Recent studies on tumor microenvironments have shown that tumor metabolism exerts a vital role in cancer progression.AIM To investigate whether lysyl oxidase(LOX) and hypoxia-inducible factor 1α(HIF1α) are prognostic and predictive biomarkers in GC.METHODS A total of 80 tissue and blood samples were collected from 140 patients admitted to our hospital between August 2008 and March 2012. Immunohistochemical staining was performed to measure the expression of LOX and HIF1α in tumor and adjacent tissues collected from patients with GC. Real-time quantitative reverse transcription polymerase chain reaction(qRT-PCR) analysis was used to detect the mRNA expression levels of LOX and HIF1α in patients with GC. In addition, single-factor analysis was applied to analyze the relationship between LOX, HIF1α and prognosis of GC.RESULTS Immunohistochemical staining suggested that the expression levels of LOX and HIF1α increased in tumor tissues from patients with GC. QRT-PCR analysis indicated that mRNA expression of LOX and HIF1α was also upregulated in tumor tissues, which was in accordance with the above results. We also detected expression of these two genes in blood samples. The expression level of LOX and HIF1α was higher in patients with GC than in healthy controls. Additional analysis showed that the expression level of LOX and HIF1α was related to the clinicopathological characteristics of GC. Expression of LOX and HIF1α increased with the number of lymph node metastases, deeper infiltration depth and later tumor–node–metastasis stages. Single-factor analysis showed that high expression of LOX and HIF1α led to poor prognosis of patients with GC.CONCLUSION LOX and HIF1α can be used as prognostic and predictive biomarkers for GC.Ya-Lin Han Li Chen Rui Qin Guan-Qing Wang Xiao-Hua Lin Guang-Hai Dai 2019World Journal of Gastroenterology2019,25,15:6

18Therapeutic effect and apoptosis mechanism of lung-tonifying and expectorant decoction on lung cancer rats with Qi deficiency and blood stasis显示文摘Objective:To explore the effect and specific mechanism of lung-tonifying and expectorant decoction on lung cancer rats with Qi deficiency and blood stasis,and aim to provide a new idea on treating the disease with traditional Chinese medicine based on syndrome differentiation.Methods:A total of 60 C57BL/6J male rats were included in the study.The model of Qi deficiency and blood stasis was established in 60 rats by using multiple-factor stimulation.About 10 rats were randomly taken to verify whether the model establishment was successful and the rest of 50 rats were divided into 5 groups with 10 rats each:blank control group,cisplatin group,low dose group,medium dose group and high dose group.The blank control group was treated with normal saline,and cisplatin group was treated with cisplatin while the other three groups were treated with lung-tonifying and expectorant decoction at different doses.The volume change in transplanted tumor,tumor inhibition rate,apoptosis rate,and expression of Bc1-2,Bax.cleaved caspase-3 and cleaved caspase-9 in 5 groups were compared.Results:The rapidest growth rate of transplanted tumor volume was observed in blank control group and the slowest in cisplatin group.The growth rate was gradually decreased with the increasing dose of lung-tonifying and expectorant decoction,and the difference in growth of tumor volume among groups was statistically significant(P<0.05).The cisplatin group showed the highest tumor inhibition rate,with dose-dependent increase(P<0.05).The apoptosis rate in low dose group was higher than blank control group but lower than high dose group(P<0.05).The apoptosis rate in medium dose group was significantly higher man blank control group(P).05).The apoptosis rate in high dose group was significantly higher than control group(P<0.05).The positive expression rates of Bel-2 and Bax in all groups showed statistically significant difference(P<0.05),while expression of cleaved caspase-3 and cleaved caspase-9 in 5 groups was significantly different,with dose-dependent increase(P<0.05).Conclusions:The lung-tonifying and expectorant decoction inhibits the proliferation of tumor cells by inducing and activating the cell apoptosis in treatment of lung cancer with Qi deficiency and blood stasis,probably with good clinical therapeutic effect.Yuan Feng Ying Zhou Ying Jiang Rui Liu Jian-Zhe Li You-Ke Xie Xue-Mei Li Fang Dai 2015Asian Pacific Journal of Tropical Medicine2015,8,11:5
19Aescin-induced reactive oxygen species play a pro-survival role in human cancer cells via ATM/AMPK/ULK1-mediated autophagy显示文摘Aescin, a natural mixture of triterpene saponins, has been reported to exert anticancer effect. Recent studies show that aescin increases intracellular reactive oxygen species (ROS) levels. However, whether the increased ROS play a role in the anticancer action of aescin remains to be explored. In this study, we demonstrated that aescin (20-80 μg/mL) dose-dependently induced apoptosis and activated mammalian target of rapamycin (mTOR)-independent autophagy in human hepatocellular carcinoma HepG2 cells and colon carcinoma HCT 116 cells. The activation of autophagy favored cancer cell survival in response to aescin, as suppression of autophagy with ATG5 siRNAs or 3-methyladenine (3-MA), a selective inhibitor of autophagy, promoted aescin-induced apoptosis in vitro, and significantly enhanced the anticancer effect of aescin in vivo. Meanwhile, aescin dose-dependently elevated intracellular ROS levels and activated Ataxia-telangiectasia mutated kinase/AMP-activated protein kinase/UNC-51-like kinase-1 (ATM/AMPK/ULK1) pathway. The ROS and ATM/AMPK/ULK1 pathway were upstream modulators of the aescin-induced autophagy, as N-acetyl-L-cysteine (NAC) or ATM kinase inhibitor (KU-55933) remarkably suppressed aescin-induced autophagy and consequently promoted aescin-induced apoptosis, whereas overexpression of ATG5 partly attenuated NAC-induced enhancement in aescin-induced apoptosis. In conclusion, this study provides new insights into the roles of aescin-mediated oxidative stress and autophagy in cancer cell survival. Our results suggest that combined administration of the antioxidants or autophagic inhibitors with aescin might be a potential strategy to enhance the anticancer effect of aescin.Bin Li Guo-liang Wu Wei Dai Gang Wang Hao-yuan Su Xue-ping Shen Rui Zhan Jia-ming Xie Zhong Wang Zheng-hong Qin Quan-gen Gao Gen-hai Shen 2018Acta Pharmacologica Sinica2018,39,12:5
20Contemporary review of minimally invasive pancreaticoduodenectomy显示文摘AIM To assess the current literature describing various minimally invasive techniques for and to review short-term outcomes after minimally invasive pancreaticoduodenectomy(PD). METHODS PD remains the only potentially curative treatment for periampullary malignancies, including, most commonly, pancreatic adenocarcinoma. Minimally invasive approaches to this complex operation have begun to be increasingly reported in the literature and are purported by some to reduce the historically high morbidity of PD associated with the open technique. In this systematic review, we have searched the literature for high-quality publications describing minimally invasive techniques for PD-including laparoscopic, robotic, and laparoscopicassisted robotic approaches(hybrid approach). We have identified publications with the largest operative experiences from well-known centers of excellence for this complex procedure. We report primarily short term operative and perioperative results and some short term oncologic endpoints. RESULTS Minimal y invasive techniques include laparoscopic, robotic and hybrid approaches and each of these techniques has strong advocates. Consistently, across all minimally invasive modalities, these techniques are associated less intraoperative blood loss than traditional open PD(OPD), but in exchange for longer operating times. These techniques are relatively equivalent in terms of perioperative morbidity and short term oncologic outcomes. Importantly, pancreatic fistula rate appears to be comparable in most minimally invasive series compared to open technique. Impact of minimally invasive technique on length of stay is mixed compared to some traditional open series. A few series have suggestedthat initiation of and time to adjuvant therapy may be improved with minimally invasive techniques, however this assertion remains controversial. In terms of shortterms costs, minimally invasive PD is significantly higher than that of OPD. CONCLUSION Minimally invasive approaches to PD show great promise as a strategy to improve short-term outcomes in patients undergoing PD, but the best results remain isolated to high-volume centers of excellence.Rui Dai Ryan S Turley Dan G Blazer 2016World Journal of Gastrointestinal Surgery2016,8,12:5
