| 2 | Anemia after gastrectomy for early gastric cancer:Long-term follow-up observational study显示文摘AIM:To identify the incidence and etiology of anemia after gastrectomy in patients with long-term follow-up after gastrectomy for early gastric cancer.METHODS:The medical records of those patients with early gastric adenocarcinoma who underwent curative gastrectomy between January 2006 and October 2007 were reviewed.Patients with anemia in the preoperative workup,cancer recurrence,undergoing systemic chemotherapy,with other medical conditions that can cause anemia,or treated during follow up with red cell transfusions or supplements for anemia were excluded.Anemia was defined by World Health Organization criteria(Hb < 12 g/dL in women and < 13 g/dL in men).Iron deficiency was defined as serum ferritin < 20 g/dL.Vitamin B12 deficiency was defined as serum vitamin B 12 < 200 pg/mL.Iron deficiency anemia was defined as anemia with concomitant iron deficiency.Anemia from vitamin B 12 deficiency was defined as megaloblastic anemia(mean cell volume > 100 fL) with vitamin B 12 deficiency.The profile of anemia over 48 mo of follow-up was analyzed.RESULTS:One hundred sixty-one patients with gastrectomy for early gastric cancer were analyzed.The incidence of anemia was 24.5% at 3 mo after surgery and increased up to 37.1% at 48 mo after surgery.The incidence of iron deficiency anemia increased during the follow up and became the major cause of anemia at 48 mo after surgery.Anemia of chronic disease and megaloblastic anemia were uncommon.The incidence of anemia in female patients was significantly higher than in male patients at 12(40.0% vs 22.0%,P = 0.033),24(45.0% vs 25.0%,P = 0.023),36(55.0% vs 28.0%,P = 0.004),and 48 mo(52.0% vs 31.0%,P = 0.022) after surgery.Patients with total gastrectomy showed significantly higher incidence of anemia than patients with subtotal gastrectomy at 48 mo after surgery(60.7% vs 31.3%,P = 0.008).The incidence of iron deficiency was significantly higher in female patients than in male patients at 6(35.4% vs 13.3%,P = 0.002),12(45.8% vs 16.8%,P < 0.001),18(52.1% vs 22.3%,P < 0.001),24(60.4% vs 20.9%,P < 0.001),36(62.5% vs 29.2%,P < 0.001),and 48 mo(66.7% vs 34.7%,P = 0.001) after surgery.CONCLUSION:Anemia was frequent after gastrectomy for early gastric cancer,with iron deficiency being the major cause.Evaluation for anemia including iron status should be performed after gastrectomy and appropriate iron replacement should be considered. | Chul-Hyun Lim Sang Woo Kim Won Chul Kim Jin Soo Kim Yu Kyung Cho Jae Myung Park In Seok Lee Myung-Gyu Choi Kyo-Young Song Hae Myung Jeon Cho-Hyun Park | 2012 | World Journal of Gastroenterology2012，18，42： | 18 |
| 3 | Generation of a monkey with MECP2 mutations by TALEN-based gene targeting显示文摘Gene editing in model organisms has provided critical insights into brain development and diseases. Here, we report the generation of a cynomolgus monkey(Macaca fascicularis) carrying MECP2 mutations using transcription activator-like effector nucleases(TALENs)-mediated gene targeting. After injecting TALENs mRNA into monkey zygotes achieved by in vitro fertilization and embryo transplantation into surrogate monkeys, we obtained one male newborn monkey with an MECP2 deletion caused by frameshifting mutation in various tissues. The monkey carrying the MECP2 mutation failed to survive after birth, due to either the toxicity of TALENs or the critical requirement of MECP2 for neural development. The level of MeCP2 protein was essentially depleted in the monkey's brain. This study demonstrates the feasibility of introducing genetic mutations in non-human primates by site-specific gene-editing methods. | Zhen Liu Xue Zhou Ying Zhu Zhi-Fang Chen Bin Yu Yan Wang Chen-Chen Zhang Yan-Hong Nie Xiao Sang Yi-Jun Cai Yue-Fang Zhang Chen Zhang Wen-Hao Zhou Qiang Sun Zilong Qiu | 2014 | Neuroscience Bulletin2014，30，3： | 17 |

| 5 | Kinematics and Dynamics Analysis of a Quadruped Walking Robot with Parallel Leg Mechanism显示文摘It is desired to require a walking robot for the elderly and the disabled to have large capacity,high stiffness,stability,etc.However,the existing walking robots cannot achieve these requirements because of the weight-payload ratio and simple function.Therefore,Improvement of enhancing capacity and functions of the walking robot is an important research issue.According to walking requirements and combining modularization and reconfigurable ideas,a quadruped/biped reconfigurable walking robot with parallel leg mechanism is proposed.The proposed robot can be used for both a biped and a quadruped walking robot.The kinematics and performance analysis of a 3-UPU parallel mechanism which is the basic leg mechanism of a quadruped walking robot are conducted and the structural parameters are optimized.The results show that performance of the walking robot is optimal when the circumradius R,r of the upper and lower platform of leg mechanism are 161.7 mm,57.7 mm,respectively.Based on the optimal results,the kinematics and dynamics of the quadruped walking robot in the static walking mode are derived with the application of parallel mechanism and influence coefficient theory,and the optimal coordination distribution of the dynamic load for the quadruped walking robot with over-determinate inputs is analyzed,which solves dynamic load coupling caused by the branches' constraint of the robot in the walk process.Besides laying a theoretical foundation for development of the prototype,the kinematics and dynamics studies on the quadruped walking robot also boost the theoretical research of the quadruped walking and the practical applications of parallel mechanism. | WANG Hongbo SANG Lingfeng HU Xing ZHANG Dianfan YU Hongnian | 2013 | Chinese Journal of Mechanical Engineering2013，26，5： | 12 |
| 6 | Severe acute pancreatitis due to tamoxifen-induced hypertriglyceridemia with diabetes mellitus显示文摘The side effects of tamoxifen are generally mild, including the effect on lipoprotein metabolism. However, there are few cases of severe tamoxifen induced hypertriglyceridemia. Hypertriglyceridemia is a marked risk factor for acute pancreatitis and approximately 2% to 5% of cases of acute pancreatitis are related to drugs. We report on tamoxifen-induced hypertriglyceridemia and acute pancreatitis in a 40 years old woman with type 2 diabetes mellitus occurred by dexamethasone. She was treated with insulin infusion and fenofibrate, and goserelin acetate was started instead of tamoxifen after discharge from the hospital. Also, probable pathogenic hypotheses about the correlation between tamoxifen and dexamethasone induced type 2 diabetes mellitus on severe acute pancreatitis are provided. Clinicians should take care of risks of severe acute pancreatitis on using tamoxifen, especially for patients with dexamethasone induced diabetes mellitus. These individuals should undergo pre-post tamoxifen lipid screening and careful history taking of drugs, including dexamethasone. | Young Ae Kim Sol Lee Ji Woong Jung Yu Jin Kwon Gyeong Bok Lee Dong Gue Shin Sang Su Park Jin Yun Yong-Seog Jang Dong Hui Cho | 2014 | Chinese Journal of Cancer Research2014，26，3： | 12 |

| 8 | Genome-wide Dissection of Co-selected UV-B Responsive Pathways in the UV-B Adaptation of Qingke显示文摘Qingke (Tibetan hulless barley) has long been cultivated and exposed to long-term and strong UV-B radiation on the Tibetan Plateau, which renders it an ideal species for elucidating novel UV-B responsive mechanisms in plants. Here we report a comprehensive metabolite profiling and metabolite-based genome-wide association study (mGWAS) using 196 diverse qingke and barley accessions. Our results demonstrated both constitutive and induced accumulation, and common genetic regulation, of metabolites from different branches of the phenylpropanoid pathway that are involved in UV-B protection. A total of 90 significant mGWAS loci for these metabolites were identified in barley-qingke differentiation regions, and a number of high-level metabolite trait alleles were found to be significantly enriched in qingke, suggesting co-selection of various phenylpropanoids. Upon dissecting the entire phenylpropanoid pathway, we identified some key determinants controlling natural variation of phenylpropanoid content, including three novel proteins, a flavone C-pentosyltransferase, a tyramine hydroxycinnamoyl acyltransferase, and a MYB transcription factor. Our study, furthermore, demonstrated co-selection of both constitutive and induced phenylpropanoids for UV-B protection in qingke. | Xingquan Zeng Hongjun Yuan Xuekui Dong Meng Peng Xinyu Jing Qijun Xu Tang Tang Yulin Wang Sang Zha Meng Gao Congzhi Li Chujin Shu Zexiu Wei Wangmu Qimei Yuzhen Basang Jiabu Dunzhu Zeqing Li Lijun Bai Jian Shi Zhigang Zheng Sibin Yu Alisdair R.Fernie Jie Luo Tashi Nyima | 2020 | Molecular Plant2020，13，1： | 9 |
| 9 | Timing of upper gastrointestinal endoscopy does not influence short-term outcomes in patients with acute variceal bleeding显示文摘AIM To examine the association between the timing of endoscopy and the short-term outcomes of acute variceal bleeding in cirrhotic patients.METHODS This retrospective study included 274 consecutive patients admitted with acute esophageal variceal bleeding of two tertiary hospitals in Korea. We adjusted confounding factors using the Cox proportional hazards model and the inverse probability weighting(IPW) method. The primary outcome was the mortality of patients within 6 wk.RESULTS A total of 173 patients received urgent endoscopy(i.e., ≤ 12 h after admission), and 101 patients received nonurgent endoscopy(> 12 h after admission). The 6-wk mortality rate was 22.5% in the urgent endoscopy group and 29.7% in the non-urgent endoscopy group, and there was no significant difference between the two groups before(P = 0.266) and after IPW(P = 0.639). The length of hospital stay was statistically different between the urgent group and non-urgent group(P = 0.033); however, there was no significant difference in the inhospital mortality rate between the two groups(8.1% vs 7.9%, P = 0.960). In multivariate analyses, timing of endoscopy was not associated with 6-wk mortality(hazard ratio, 1.297; 95% confidence interval, 0.806-2.089; P = 0.284).CONCLUSION In cirrhotic patients with acute variceal bleeding, the timing of endoscopy may be independent of short-term mortality. | Jeong-Ju Yoo Young Chang Eun Ju Cho Ji Eun Moon Sang Gyune Kim Young Seok Kim Yun Bin Lee Jeong-Hoon Lee Su Jong Yu Yoon Jun Kim Jung-Hwan Yoon | 2018 | World Journal of Gastroenterology2018，24，44： | 8 |
| 10 | Evaluation of esophageal function in patients with esophageal motor abnormalities using multichannel intraluminal impedance esophageal manometry显示文摘AIM: To evaluate the functional aspect of esophageal motility in healthy subjects and in patients who were referred for esophageal function testing using multichannel intraluminal impedance-esophageal manometry (MII-EM), and to assess the clinical utility of MII-EM. METHODS: From September 2003 to January 2004, we performed the MII-EM on healthy volunteers and all the patients who were referred for esophageal function testing. Each patient received 10 liquid and 10 viscous swallows. We analyzed the results, the impedance and the manometric findings. Some of the subjects had additional ambulatory 24-h pH study performed to diagnose gastroesophageal reflux disease (GERD). RESULTS: Among 89 studied subjects, the MII-EM findings showed normal esophageal motility in 50 (56.17%), ineffective esophageal motility (IEM) in 17 (19.10%), nutcracker esophagus in 7 (7.86%), achalasia in 4 (4.49%), and scleroderma esophagus in 11 (12.35%) cases. The completeness and the speed of bolus transit were in the order of nutcracker esophagus, normal manometry and IEM. Some of the swallows showing normal manometry and IEM had incomplete transit. In the achalasia and scleroderma esophagus, almost all the swallows had incomplete transit. The body amplitudes were higher for the swallows with complete transit than for the swallows with incomplete transit. There was not a significant difference in the manometric and impedance findings between the subjects with and without GERD. CONCLUSION: MII-EM is a useful tool in assessing theesophageal function in the patients having esophageal motility abnormality. The primary factors influencing the bolus transit are the amplitude of the esophageal body and normal peristalsis. | Yu Kyung Cho Myung-Gyu Choi Jae Myung Park Jung Hwan Oh Chang Nyol Paik Joon Wook Lee In Seok Lee Sang Woo Kim In-Sik Chung | 2006 | World Journal of Gastroenterology2006，12，39： | 8 |
| 11 | Proton therapy for hepatocellular carcinoma:Current knowledges and future perspectives显示文摘Hepatocellular carcinoma(HCC) is the second leading cause of cancer-related death, as few patients can be treated with currently available curative local modalities. In patients with HCC where curative modalities are not feasible, radiation therapy(RT) has emerged as an alternative or combination therapy. With the development of various technologies, RT has been increasingly used for the management of HCC. Among these advances, proton beam therapy(PBT) has several unique physical properties that give it a finite range in a distal direction, and thus no exit dose along the beam path. Therefore, PBT has dosimetric advantages compared with X-ray therapy for the treatment of HCC. Indeed, various reports in the literature have described the favorable clinical outcomes and improved safety of PBT for HCC patients compared with X-ray therapy. However, there are some technical issues regarding the use of PBT in HCC, including uncertainty of organ motion and inaccuracy during calculation of tissue density and beam range, all of which may reduce the robustness of a PBT treatment plan. In this review, we discuss the physical properties, current clinical data, technical issues, and future perspectives on PBT for the treatment of HCC. | Gyu Sang Yoo Jeong Il Yu Hee Chul Park | 2018 | World Journal of Gastroenterology2018，24，28： | 8 |

| 13 | One-year clinical outcomes in invasive treatment strategies for acute ST-elevation myocardial infarction complicated by cardiogenic shock in eld-erly patients显示文摘Objective To investigate the clinical outcomes of an invasive strategy for elderly (aged≥75 years) patients with acute ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS). Methods Data on 366 of 409 elderly CS patients from a total of 6,132 acute STEMI cases enrolled in the Korea Acute Myocardial Infarction Registry between January 2008 and June 2011, were collected and analyzed. In-hospital deaths and the 1-month and 1-year survival rates free from major adverse cardiac events (MACE;defined as all cause death, myocardial infarction, and target vessel revascularization) were reported for the patients who had undergone invasive (n=310) and conservative (n=56) treatment strategies. Results The baseline clinical characteristics were not significantly different between the two groups. There were fewer in-hospital deaths in the invasive treatment strategy group (23.5%vs. 46.4%, P<0.001). In addition, the 1-year MACE-free survival rate after invasive treatment was significantly lower compared with the conservative treatment (51%vs. 66%, P=0.001). Conclusions In elderly patients with acute STEMI complicated by CS, the outcomes of invasive strategy are similar to those in younger patients at the 1-year follow-up. | Yeon Pyo Yoo Ki-Woon Kang Hyeon Soo Yoon Jin Cheol Myung Yu Jeong Choi Won Ho Kim Sang Hyun Park Kyung Tae Jung Myung Ho Jeong | 2013 | Journal of Geriatric Cardiology2013，10，3： | 7 |
| 14 | Catalytic performance of hierarchical H-ZSM-5/MCM-41 for methanol dehydration to dimethyl ether显示文摘Micro-mesoporous composite molecular sieves H-ZSM-5/MCM-41 were prepared by the hydrothermal technique with alkali-treated H-ZSM-5zeolite as the source and characterized by scanning electron microscopy,transmission electron microscopy,energy dispersive spectroscopy,X-ray diffraction,N2 adsorption-desorption measurement and NH3 temperature-programmed desorption.The catalytic performances for the methanol dehydration to dimethyl ether over H-ZSM-5/MCM-41 were evaluated.Among these catalysts,H-ZSM-5/MCM-41 prepared with NaOH dosage (nNa/nSi) varying from 0.4 to 0.47 presented excellent catalytic activity with more than 80%methanol conversion and 100%dimethyl ether selectivity in a wide temperature range of 170—300℃,and H-ZSM-5/MCM-41 prepared with nNa/nSi=0.47 showed constant methanol conversion of about 88.7%,100% dimethyl ether selectivity and excellent lifetime at 220℃.The excellent catalytic performances were due to the highly active and uniform acidic sites and the hierarchical porosity in the micro-mesoporous composite molecular sieves.The catalytic mechanism of H-ZSM-5/MCM-41 for the methanol dehydration to dimethyl ether process was also discussed. | Yu Sang Hongxiao Liu Shichao He Hansheng Li Qingze Jiao Qin Wu Kening Sun | 2013 | Journal of Energy Chemistry2013，22，5： | 7 |

| 16 | 3-Dimensional liver volume assessment in patients with hepatitis B virus-related liver cirrhosis during long-term oral nucleos(t)ide analogues therapy显示文摘AIM To assess the effect of long-term oral nucleos(t)ide analogues(NUCs) therapy on liver volume change in patients with suppress hepatitis B virus(HBV)-related liver cirrhosis.METHODS We reviewed the data of na?ve patients with HBVrelated liver cirrhosis, who had taken oral NUCs therapy, between 2003 and 2007 at Chonbuk University Hospital. We analyzed two consecutive sets of abdominal computerized tomography scans-one at the time oftreatment initiation and another at the second-year follow-up. Liver volume was calculated by 3-dimensional liver extraction volumetry program.RESULTS A total of 55 patients(34 males) were included. There was 114.3 m L ± 167.8 m L(12.9% ± 17.9%) of increase in liver volume during the two years of NUCs therapy(993.8 m L ± 242.8 m L at baseline vs 1108.1 m L ± 263.3 m L at two-year follow-up, P < 0.001). The ratio of the measured baseline liver volume to the estimated standard liver volume was improved from 70.8% to 78.0%. An increase in liver volume was shown not only in patients with compensated cirrhosis(P = 0.046) but also in those with decompensated cirrhosis(P < 0.001). Significant factors for volume increases were Child-Turcotte-Pugh grade and model for end-stage liver disease score improvement without virological breakthrough. In multiple linear regression analysis, delta albumin and delta alanine aminotransferase levels showed a significant association with the increase in liver volume(P = 0.002 and 0.005, respectively).CONCLUSION Long-term oral NUCs therapy in patients with HBVrelated liver cirrhosis lead to significant increase in liver volume assessed with 3-dimensional liver extraction volumetry program. | Chang Hun Lee In Hee Kim Jin Chang Moon Seung Young Seo Seong Hun Kim Sang Wook Kim Seung Ok Lee Soo Teik Lee Dae Ghon Kim Jae Do Yang Hee Chul Yu | 2017 | World Journal of Gastroenterology2017，23，2： | 6 |

| 18 | The Relationship between Polymorphisms at 17 Gene Sites and Hypertension among the Aboriginal Tibetan People显示文摘Objective The incidence of hypertension in Tibet ranks highest among all Chinese provinces. This may be due to genetic changes caused by Tibet's unique natural environment and agrarian lifestyle, prompting us to investigated the relationship between gene polymorphisms and hypertension. Methods Blood samples were collected from 229 hypertensive participants and 372 healthy (control) participants from five Tibetan counties. Seventeen single nucleotide polymorphisms were investigated for their connection to hypertension. Results The C allele at rs2070744 of the NOS3 gene was shown to be significantly associated with hypertension (P=0.0443; OR=1.636). Additionally, the T allele of rs4961 of the ADD gene was correlated with hypertension in women (P=0.03124; OR=1.584). Conclusion In this study we found that the NOS3 and ADD genes were related to a high incidence of hypertension among Tibetans. NOS3 gene plays a role in regulating vascular tone and blood vessel diameter, which may be altered by the low-oxygen environment of Tibet. ADD is involved in water and salt metabolism, which is consistent with the high-salt diet of Tibetans. The correlations elucidated by our study were different from those of other ethnic groups, indicating that these findings may be specific to the Tibetan people. | LI Kui LIANG Yu SUN Yin ZHANG Ling Xia YI Xin CHEN Yong GU SANG LA MU WANG Jian | 2012 | Biomedical and Environmental Sciences2012，25，5： | 6 |
