| 1 | Anthropogenic emission inventories in China:a review显示文摘The development of reliable anthropogenic emission inventories is essential for both understanding the sources of air pollution and designing effective air-pollution-control measures in China. However, it is challenging to quantify emissions in China accurately, given the variety of contributing sources, the complexity of the technology mix and the lack of reliable measurements. Over the last two decades,tremendous efforts have been made to improve the accuracy of emission inventories, and significant improvements have been realized. More reliable statistics and survey-based data have been used to reduce the uncertainties in activity rates and technology distributions. Local emission factors and source profiles covering various sources have been measured and reported. Based on these local databases, improved emission inventory models have been developed for power plants, large industrial plants and the residential,transportation and agricultural sectors. In this paper, we review the progress that has been made in developing inventories of anthropogenic emissions in China. We first highlight the major updates that have been made to emission inventory models and the underlying data by source category. We then summarize the sector-based estimates of emissions of different species contained in current inventories. The progress that has been made in the development of model-ready emissions is also presented. Finally, we suggest future directions for further improving the accuracy of emission inventories in China. | Meng Li Huan Liu Guannan Geng Chaopeng Hong Fei Liu Yu Song Dan Tong Bo Zheng Hongyang Cui Hanyang Man Qiang Zhang Kebin He | 2017 | National Science Review2017，4，6： | 100 |
| 2 | A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s). | QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China | 2003 | Chinese Science Bulletin2003，48，10： | 121 |

| 5 | Risk factors for complications associated with upper gastrointestinal foreign bodies显示文摘AIM: To investigate predictive risk factors associated with complications in the endoscopic removal of foreign bodies from the upper gastrointestinal tract.METHODS: We retrospectively reviewed the medical records of 194 patients with a diagnosis of foreign body impaction in the upper gastrointestinal tract,confirmed by endoscopy,at two university hospital in South Korea.Patient demographic data,including age,gender,intention to ingestion,symptoms at admission,and comorbidities,were collected.Clinical features of the foreign bodies,such as type,size,sharpness of edges,number,and location,were analyzed.Endoscopic data those were analyzed included duration of foreign body impaction,duration of endoscopic performance,endoscopic device,days of hospitalization,complication rate,30-d mortality rate,and the number of operationsrelated to foreign body removal.RESULTS: The types of upper gastrointestinal foreign bodies included fish bones,drugs,shells,meat,metal,and animal bones.The locations of impacted foreign bodies were the upper esophagus(57.2%),mid esophagus(28.4%),stomach(10.8%),and lower esophagus(3.6%).The median size of the foreign bodies was 26.2 ± 16.7 mm.Among 194 patients,endoscopic removal was achieved in 189,and complications developed in 51 patients(26.9%).Significant complications associated with foreign body impaction and removal included deep lacerations with minor bleeding(n = 31,16%),ulcer(n = 11,5.7%),perforation(n = 3,1.5%),and abscess(n = 1,0.5%).Four patients underwent operations because of incomplete endoscopic foreign body extraction.In multivariate analyses,risk factors for endoscopic complications and failure were sharpness(HR = 2.48,95%CI: 1.07-5.72; P = 0.034) and a greater than 12-h duration of impaction(HR = 2.42,95%CI: 1.12-5.25,P = 0.025).CONCLUSION: In cases of longer than 12 h since foreign body ingestion or sharp-pointed objects,rapid endoscopic intervention should be provided in patients with ingested foreign bodies. | Kyong Hee Hong Yoon Jae Kim Jae Hak Kim Song Wook Chun Hee Man Kim Jae Hee Cho | 2015 | World Journal of Gastroenterology2015，21，26： | 35 |
| 6 | Blood Lipid Profile and Prevalence of Dyslipidemia in Chinese Adults显示文摘Objective To investigate the plasma lipid levels in a national representative sample of subjects and to determine the prevalence of dyslipidemia in the Chinese population.Methods Plasma lipid profile was analyzed using the data obtained during the Chinese national nutrition and health survey(CNHS)in 2002 which involved 14 252 participants at the age of 18 years or older.Results The mean levels of total cholesterol(TC),triglyceride(TG)and high density lipoprotein cholesterol(HDL-C)in the participants were 3.81 mmol/L,1.10 mmol/L,and 1.30 mmol/L,respectively.In the groups of participants at the age of 18-44 years,45-59 years,and over 60 years the mean TC level was 3.70 mmol/L,4.09 mmol/L and 4.21 mmol/L,respectively,and the mean TG level was 07 mmol/L,1.21 mmol/L,1.20 mmol/L,1.29 mmol/L,1.33 mmol/L,and 1.33 mmol/L,respectively.The prevalence of dyslipidemia in Chinese adults was 18.6% and 22.2% in males and 15.9% in females.Dyslipidemia prevalence was higher in urban districts than in rural areas(21.0% vs.17.7%).The prevalence of hypercholesterolemia,hypertriglyceridemia,and low HDL cholesterol was 2.9%,11.9%,and 7.4% respectively among the participants.Conclusion Dyslipidemia has become one of the important health risk factors in the Chinese population.There is no significantly difference in the prevalence of dyslipidemia between the groups of participants at the age of 45-59 years and over 60 years.This study provides important lipid profile data for policy making and guideline development for the prevention of dyslipidemia in the Chinese population. | WEN-HUA ZHAO JIAN ZHANG YI ZHAI YUE YOU QING-QING MAN CHUN-RONG WANG HONG LI YING LI XIAO-GUANG YANG | 2007 | Biomedical and Environmental Sciences2007，20，4： | 22 |
| 7 | Atomically dispersed Au_1 catalyst towards efficient electrochemical synthesis of ammonia显示文摘Tremendous efforts have been devoted to explore energy-efficient strategies of ammonia synthesis to replace Haber–Bosch process which accounts for 1.4% of the annual energy consumption. In this study,atomically dispersed Au_1 catalyst is synthesized and applied in electrochemical synthesis of ammonia under ambient conditions. A high NH_4^+ Faradaic efficiency of 11.1% achieved by our Au_1 catalyst surpasses most of reported catalysts under comparable conditions. Benefiting from efficient atom utilization, an NH_4^+ yield rate of 1,305 lg h^(-1) mg_(Au)^(-1) has been reached, which is roughly 22.5 times as high as that by supported Au nanoparticles. We also demonstrate that by employing our Au_1 catalyst, NH4+can be electrochemically produced directly from N_2 and H_2 with an energy utilization rate of 4.02 mmol kJ^(-1). Our study provides a possibility of replacing the Haber–Bosch process with environmentally benign and energy-efficient electrochemical strategies. | Xiaoqian Wang Wenyu Wang Man Qiao Geng Wu Wenxing Chen Tongwei Yuan Qian Xu Min Chen Yan Zhang Xin Wang Jing Wang Jingjie Ge Xun Hong Yafei Li Yuen Wu Yadong Li | 2018 | Science Bulletin2018，63，19： | 22 |
| 8 | Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic. | Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan | 2020 | National Science Review2020，7，9： | 20 |
| 9 | Laparoscopy-assisted pylorus-preserving gastrectomy for early gastric cancer: A retrospective study of long-term functional outcomes and quality of life显示文摘BACKGROUND Laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) was known to have benefits of function-preserving surgery compared to laparoscopy-assisted distal gastrectomy (LADG). However, in clinical settings, delayed gastric emptying and esophageal reflux following LAPPG can be serious issues, making surgeons reluctant to perform LAPPG. It is unclear that LAPPG had better longterm functional outcomes and quality of life compared to LADG. AIM To evaluate the long-term functional outcomes and patient-reported quality of life of LAPPG compared to those of LADG. METHODS We reviewed the clinicopathological data of 195 patients who underwent LADG with Billroth II anastomosis and 101 patients who underwent LAPPG for cT1N0 gastric cancer in the middle third of the stomach between 2012 and 2015. Postoperative complications, nutritional parameters, and survey results of the European Organization for Research and Treatment of Cancer Questionnaire C30 and STO22 questionnaire were compared between the two groups. RESULTS The serum hemoglobin level was significantly higher in the LAPPG group than in the LADG group (P < 0.001). In the endoscopic findings, incidence of bile reflux was lower (P < 0.001);however, the incidence of residual food was higher in the LAPPG group than in the LADG group (P < 0.001). Regarding the quality of life score, the LAPPG group had a better physical functioning score (86.7 vs 90.0, P = 0.032) but also greater pain and reflux when compared to the LADG group [8.3 vs 16.7 in pain, 11.1 (interquartile range, 0, 22.2) vs 11.1 (interquartile range, 11.1, 33.3) in reflux, P = 0.034 and 0.001, respectively]. CONCLUSION LAPPG is beneficial to recovery of anemia and to bile reflux, however, it might be unfavorable in terms of pain and reflux symptoms compared to LADG with Billroth II anastomosis. | Bang Wool Eom Boram Park Hong Man Yoon Keun Won Ryu Young-Woo Kim | 2019 | World Journal of Gastroenterology2019，25，36： | 18 |
| 10 | Phase 1 clinical trial demonstrated that MUC1 positive metastatic seminal vesicle cancer can be effectively eradicated by modified Anti-MUC1 chimeric antigen receptor transduced T cells显示文摘Recent progress in chimeric antigen receptor-modified T-cell(CAR-T cell) technology in cancer therapy is extremely promising, especially in the treatment of patients with B-cell acute lymphoblastic leukemia. In contrast, due to the hostile immunosuppressive microenvironment of a solid tumor, CAR T-cell accessibility and survival continue to pose a considerable challenge, which leads to their limited therapeutic efficacy. In this study, we constructed two anti-MUC1 CAR-T cell lines. One set of CAR-T cells contained SM3 single chain variable fragment(sc Fv) sequence specifically targeting the MUC1 antigen and co-expressing interleukin(IL) 12(named SM3-CAR). The other CAR-T cell line carried the SM3 sc Fv sequence modified to improve its binding to MUC1 antigen(named p SM3-CAR) but did not co-express IL-12. When those two types of CAR-T cells were injected intratumorally into two independent metastatic lesions of the same MUC1+ seminal vesicle cancer patient as part of an interventional treatment strategy, the initial results indicated no side-effects of the MUC1 targeting CAR-T cell approach, and patient serum cytokines responses were positive. Further evaluation showed that p SM3-CAR effectively caused tumor necrosis, providing new options for improved CAR-T therapy in solid tumors. | Fengtao You Licui Jiang Bozhen Zhang Qiang Lu Qiao Zhou Xiaoyang Liao Hong Wu Kaiqi Du Youcai Zhu Huimin Meng Zhishu Gong Yunhui Zong Lei Huang Man Lu Jirong Tang Yafen Li Xiaochen Zhai Xiangling Wang Sisi Ye Dan Chen Lei Yuan Lin Qi Lin Yang | 2016 | Science China(Life Sciences)2016，59，4： | 16 |

| 12 | Role of surgical resection for multiple hepatocellular carcinomas显示文摘AIM:To clarify the role of surgical resection for multiple hepatocellular carcinomas(HCCs)compared to transarterial chemoembolization(TACE)and liver transplantation(LT). METHODS:Among the HCC patients who were managed at Yonsei University Health System between January 2003 and December 2008,160 patients who met the following criteria were retrospectively enrolled:(1) two or three radiologically diagnosed HCCs;(2)no radiologic vascular invasion;(3)Child-Pugh class A;(4) main tumor smaller than 5 cm in diameter;and(5) platelet count greater than 50 000/mm3.Long-term outcomes were compared among the following three treatment modalities:surgical resection or combined radiofrequency ablation(RFA)(n=36),TACE(n=107), and LT(n=17).The survival curves were computed using the Kaplan-Meier method and compared with a log-rank test.To identify the patients who gained a survival benefit from surgical resection,we also investigated prognostic factors for survival following surgical resection.Multivariate analyses of the prognostic factors for survival were performed using the Cox proportional hazard model. RESULTS:The overall survival(OS)rate was significantly higher in the surgical resection group than in the TACE group(48.1%vs 28.9%at 5 years,P<0.005). LT had the best OS rate,which was better than that of the surgical resection group,although the difference was not statistically significant(80.2%vs 48.1%at 5 years,P=0.447).The disease-free survival rates were also significantly higher in the LT group than in the surgical resection group(88.2%vs 11.2%at 5 years, P<0.001).Liver cirrhosis was the only significant prognostic factor for poor OS after surgical resection. Clinical liver cirrhosis rates were 55.6%(20/36)in the resection group and 93.5%(100/107)in the TACE group.There were 19 major and 17 minor resections. En bloc resection was performed in 23 patients,multisite resection was performed in 5 patients,and combined resection with RFA was performed in 8 patients. In the TACE group,only 34 patients(31.8%)were recorded as having complete remission after primary TACE.Seventy-two patients(67.3%)were retreated with repeated TACE combined with other therapies. In patients who underwent surgical resection,the 16 patients who did not have cirrhosis had higher 5-year OS and disease-free survival rates than the 20 patients who had cirrhosis(80.8%vs 25.5%5-year OS rate, P=0.006;22.2%vs 0%5-year disease-free survival rate,P=0.048).Surgical resection in the 20 patients who had cirrhosis did not provide any survival benefit when compared with TACE(25.5%vs 24.7%5-year OS rate,P=0.225).Twenty-nine of the 36 patients who underwent surgical resection experienced recur-rence.Of the patients with cirrhosis,80%(16/20) were within the Milan criteria at the time of recurrence CONCLUSION:Among patients with two or three HCCs, no radiologic vascular invasion,and tumor diameters≤ 5 cm,surgical resection is recommended only in those without cirrhosis. | Sung Hoon Choi Gi Hong Choi Seung Up Kim Jun Yong Park Dong Jin Joo Man Ki Ju Myoung Soo Kim Jin Sub Choi Kwang Hyub Han Soon Il Kim | 2013 | World Journal of Gastroenterology2013，19，3： | 12 |
| 13 | Garcinol inhibits esophageal cancer metastasis by suppressing the p300 and TGF-β1 signaling pathways显示文摘Metastasis causes the main lethality in esophageal cancer patient.Garcinol,a natural compound extracted from Gambogic genera,is a histone acetyltransferase(HAT)inhibitor that has shown anticancer activities such as cell cycle arrest and apoptosis induction.In this study,we investigated the effects of garcinol on the metastasis of esophageal cancer in vitro and in vivo.We found that garcinol(5-15μM)dose-dependently inhibited the migration and invasion of human esophageal cancer cell lines KYSE150 and KYSE450 in wound healing,transwell migration,and Matrigel invasion assays.Furthermore,garcinol treatment dose-dependently decreased the protein levels of p300/CBP(transcriptional cofactors and HATs)and p-Smad2/3 expression in the nucleus,thus impeding tumor cell proliferation and metastasis.Knockdown of p300 could inhibit cell metastasis,but CBP knockdown did not affect the cell mobility.It has been reported that TGF-β1 stimulated the phosphorylation of Smad2/3,which directly interact with p300/CBP in the nucleus,and upregulating HAT activity of p300.We showed that garcinol treatment dose-dependently suppressed TGF-β1-activated Smad and non-Smad pathway,inhibiting esophageal cancer cell metastasis.In a tail vein injection pulmonary metastasis mouse model,intraperitoneal administration of garcinol(20 mg/kg)or 5-FU(20 mg/kg)significantly decreased the number of lung tumor nodules and the expression levels of Ki-67,p300,and p-Smad2/3 in lung tissues.In conclusion,our study demonstrates that garcinol inhibits esophageal cancer metastasis in vitro and in vivo,which might be related to the suppression of p300 and TGF-β1 signaling pathways,suggesting the therapeutic potential of Garcinol for metastatic tumors. | Jing Wang Man Wu Dan Zheng Hong Zhang Yue Lv Li Zhang Hong-sheng Tan Hua Zhou Yuan-zhi Lao Hong-xi Xu | 2020 | Acta Pharmacologica Sinica2020，41，1： | 12 |
| 14 | Covalently closed-circular hepatitis B virus DNA reduction with entecavir or lamivudine显示文摘AIM: To investigate the reduction in hepatitis B virus(HBV) covalently closed-circular DNA(ccc DNA) with entecavir(ETV) or lamivudine(LAM). METHODS: This analysis included patients who had participated in the randomized Phase Ⅲ study ETV-022 comparing ETV vs LAM in nucleos(t)ide-naive, HBe Agpositive patients. Patients received ETV(0.5 mg daily) or LAM(100 mg daily) for a minimum of 52 wk. Patients were eligible to participate in this sub-study if they had paired biopsies at baseline and week 48 with evaluable measurements for hepatic HBV ccc DNA and total hepatic HBV DNA. The main objective was to compare changes in hepatic HBV ccc DNA and total hepatic HBV DNA at week 48 of ETV or LAM treatment, which was a secondary endpoint of study ETV-022. Additional post hoc analyses included linear regression analyses to assess associations of baseline levels and on-treatment changes of ccc DNA with other baseline factors [sex,age, serum HBV DNA, alanine aminotransferase(ALT), Knodell necroinflammatory score, Ishak fibrosis score, total hepatic HBV DNA, and HBV genotype], or ontreatment factors(changes from baseline at week 48 in serum HBV DNA, ALT, Knodell necroinflammatory score, Ishak fibrosis score, total hepatic HBV DNA, and HBe Ag loss at week 48).RESULTS: Overall, 305 patients(ETV = 159; LAM = 146) of ETV-022 had paired baseline and week 48 liver biopsies with evaluable measurements for hepatic HBV ccc DNA and total hepatic HBV DNA, and were included in this analysis. Baseline demographics and disease characteristics were comparable between the two arms. After 48 wk, ETV resulted in significantly greater reductions in hepatic HBV ccc DNA [-0.9 log10 copies/human genome equivalent(HGEq) vs-0.7 log10 copies/HGEq; P = 0.0033] and total hepatic DNA levels(-2.1 log10 copies/HGEq vs-1.6 log10 copies/HGEq; P < 0.0001) than LAM. Virologic, biochemical, and histologic response rates at week 48 were also greater with ETV than with LAM. Baseline HBV ccc DNA levels were positively associated with baseline levels of serum HBV DNA and total hepatic HBV DNA, and negatively associated with HBV genotype F. On-treatment changes in HBV ccc DNA levels were negatively associated with baseline levels of serum HBV DNA and baseline ALT, and were positively associated with on-treatment changes in the levels of serum HBV DNA, total hepatic HBV DNA levels, and ALT, change in Knodell necroinflammatory score, and HBe Ag loss.CONCLUSION: Forty-eight weeks of ETV resulted in greater reductions in ccc DNA and total hepatic HBV DNA than LAM, but long-term therapy may be needed for ccc DNA elimination. | Scott Bowden Stephen Locarnini Ting-Tsung Chang You-Chen Chao Kwang-Hyub Han Robert G Gish Robert A de Man Miao Yu Cyril Llamoso Hong Tang | 2015 | World Journal of Gastroenterology2015，21，15： | 11 |
| 15 | Analysis of Allergens in 5473 Patients with Allergic Diseases in Harbin, China显示文摘Objective To analyze the allergic status to common inhalant allergens and food allergens in clinical patients in Harbin in northeastern China and provide evidence to develop the prevention strategy of allergic disease. Methods The data were collected from 5473 patients with clinical suspected allergic diseases seeking medical care in the Second Affiliated Hospital of Harbin Medical University. Among these patients, 2530(46.2%) were males aged 0-86 years, the youngest was only 1 month old and 2579(47.1%) were young children and teenagers. The serum specific Immunoglobulin E(sIgE) to 14 kinds of common allergens and serum total IgE were detected by using AllergyScreen test(Mediwiss Analytic GmbH, Moers, Germany). Results In 5473 subjects the positive rate of sIgE was 33.1%(n=1813). Cow milk(6.9%) and wheat(3.1%) were the most common food allergens, followed by house dust mite mix(12.5%) and mould mix(9.4%) and the age and gender specific differences in the positive rate were significant. For the children aged <7 years the positive rates to cow milk, beef-mutton, and egg white/egg yolk were high, but the positive rates to house dust mite mix, ragweed estragon, and mould mix were low(P<0.05). For the adults the positive rates to aeroallergens were high while the rates to food allergens were low. Conclusion The results from this study showed that the food allergens in Harbin had geographic characteristics, which support the viewpoint that the environment factors play an important role in the incidence of allergic diseases.

Compared with the conventional laparoscopy-assisted distal gastrectomy(LADG), totally laparoscopic distal gastrectomy(TLDG) involves intracorporeal reconstruction, which can avoid the additional incision, resulting in pain reduction and early recovery. This study aimed to compare the short-term postoperative outcomes of TLDG vs. LADG in gastric cancer in a high-volume center.Methods: A retrospective cohort study was conducted on 1,322 patients who underwent laparoscopic distal gastrectomy from June 2012 to June 2017 at the National Cancer Center, Korea. LADG was performed in the early period before July 2015, and TLDG was applied in the later period. Postoperative short-term outcomes were compared in terms of complication and clinical course between the two groups. Pain score was measured by rating the pain intensity from 0 to 10 points on postoperative day(POD) 1 and 3.Results: A total of 667 patients underwent LADG and 655 patients underwent TLDG. Clinicopathologic characteristics were not different in both groups. Intraoperative estimated blood loss(EBL) was significantly lower in the TLDG group(P<0.001). Postoperative pain scores were significantly lower in the TLDG group than in the LADG group on POD 1(5.1±1.5 vs. 4.8±1.4, P=0.015). First flatus passage after operation was significantly earlier in the TLDG group(3.4±0.8 d vs. 3.2±0.6 d, P<0.001). There were no differences in postoperative complications and hospital stay between the two groups.Conclusions: Based on the reported short-term postoperative outcomes, TLDG is safe and feasible as well as LADG. Moreover, compared with LADG, TLDG can reduce intraoperative EBL and postoperative pain and enhance the bowel motility in gastric cancer surgery. | Won Ho Han Amir Ben Yehuda Deok-Hee Kim Seung Geun Yang Bang Wool Eom Hong Man Yoon Young-Woo Kim Keun Won Ryu | 2018 | Chinese Journal of Cancer Research2018，30，5： | 11 |
| 17 | Endoscopic treatment of duodenal fistula after incomplete closure of ERCP-related duodenal perforation显示文摘Endoscopic retrograde cholangiopancreatography(ERCP)is an important diagnostic and therapeutic modality for various pancreatic and biliary diseases.The most common ERCP-induced complication is pancreatitis,whereas hemorrhage,cholangitis,and perforation occur less frequently.Early recognition and prompt treatment of these complications may minimize the morbidity and mortality.One of the most serious complications is perforation.Although the incidence of duodenal perforation after ERCP has decreased to<1.0%,severe cases still require prolonged hospitalization and urgent surgical intervention,potentially leading to permanent disability or mortality.Surgery remains the mainstay treatment for perforations of the luminal organs of the gastrointestinal tract.However,evidence from case reports and case series support a beneficial role of endoscopic clipping in the closure of these defects.Duodenal fistulas are usually a result of sphincterotomies,perforated duodenal ulcers,or gastrectomy.Other causative factors include Crohn's disease,trauma,pancreatitis,and cancer.The majority of duodenal fistulas heal with nonoperative management.Those that fail to heal are best treated with gastrojejunostomy.Recently proposed endoscopic approaches for managing gastrointestinal leaks caused by fistulas include fibrin glue injection and positioning of endoclips.Our patient developed a secondary persistent duodenal fistula as a result of previous incomplete closure of duodenal perforation with hemoclips and an endoloop.The fistula was successfully repaired by additional clipping and fibrin glue injection. | Dong Wook Yu Man Yong Hong Seung Goun Hong | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，6： | 10 |
