| 1 | Gastric leptomeningeal carcinomatosis: Multi-center retrospective analysis of 54 cases显示文摘AIM: To identify the clinical features and outcomes of infrequently reported leptomeningeal carcinomatosis (LMC) of gastric cancer.METHODS: We analyzed 54 cases of cytologically confirmed gastric LMC at four institutions from 1994 to 2007.RESULTS: The male-to-female ratio was 32:22, and the patients ranged in age from 28 to 78 years (median,48.5 years). The majority of patients had advanced disease at initial diagnosis of gastric cancer. The clini-cal or pathologic tumor, node and metastasis stage ofthe primary gastric cancer wasin 38 patients (70%).The median interval from diagnosis of the primarymalignancy to the diagnosis of LMC was 6.3 mo, rang-ing between 0 and 73.1 mo. Of the initial endoscopic f indings for the 45 available patients, 23 (51%) of the patients were Bormann typeand 15 (33%) patientswere Bormann type. Pathologically, 94% of cases proved to be poorly differentiated adenocarcinomas. Signet ring cell component was also observed in 40% of patients. Headache (85%) and nausea/vomiting (58%) were the most common presenting symptoms of LMC. A gadolinium-enhanced magnetic resonance imaging was conducted in 51 patients. Leptomeningeal enhancement was noted in 45 cases (82%). Intrathecal (IT) chemotherapy was administered to 36 patients-primarily methotrexate alone (61%), but also in combi-nation with hydrocortisone/± Ara-C (39%). The median number of IT treatments was 7 (range, 1-18). Concomitant radiotherapy was administered to 18 patients, and concomitant chemotherapy to seven patients. Sev-enteen patients (46%) achieved cytological negative conversion. Median overall survival duration from the diagnosis of LMC was 6.7 wk (95% CI: 4.3-9.1 wk). In the univariate analysis of survival duration, hemoglobin, IT chemotherapy, and cytological negative conversion showed superior survival duration (P = 0.038, P = 0.010, and P = 0.002, respectively). However, in our multivariate analysis, only cytological negative conversion was predictive of relatively longer survival duration (3.6, 6.7 and 14.6 wk, P = 0.030, RR: 0.415, 95% CI: 0.188-0.918).CONCLUSION: Although these patients had a fatal clinical course, cytologic negative conversion by IT chemotherapy may improve survival. | Sung Yong Oh Su-Jin Lee Jeeyun Lee Suee Lee Sung-Hyun Kim Hyuk-Chan Kwon Gyeong-Won Lee Jung Hun Kang In Gyu Hwang Joung-Soon Jang Ho Yeong Lim Young Suk Park Won Ki Kang Hyo-Jin Kim | 2009 | World Journal of Gastroenterology2009，15，40： | 10 |
| 2 | Clinicopathologic significance of expression of nuclear factor-kB RelA and its target gene products in gastric cancer patients显示文摘AIM:To assess the prognostic significance of nuclear factor-kB (NF-kB) and its target genes in gastric cancer. METHODS:The tumor tissues of 115 patients with gastric cancer were immunohistochemically evaluated using monoclonal antibodies against NF-kB RelA. Preoperative serum levels of vascular endothelial growth factor (VEGF), interleukin-6 (IL-6) were assessed via enzyme-linked immuno-sorbent assay. C-reactive protein (CRP) and serum amyloid A (SAA) were measured via immunotrubidimetry. RESULTS:Positive rate of NF-kB RelA was 42.6%. NF-kB RelA expression in tumor tissues was also related to serum levels of IL-6 (P = 0.044) and CRP (P = 0.010). IL-6, SAA, CRP were related to depth of invasion, VEGF and SAA were correlated with lymph node metastasis. IL-6, VEGF, SAA and CRP were related to the stage. Univariate analysis demonstrated that immunostaining of NF-kB RelA, levels of IL-6, VEGF, SAA were significantly related with both disease free survival and over-all survival (OS). Multivariate analysis verified that NF-kB RelA [hazard ratio (HR): 3.40, P = 0.024] and SAA (HR: 3.39, P = 0.045) were independently associated with OS. CONCLUSION: Increased expression of NF-kB RelA and high levels of serum SAA were associated with poor OS in gastric cancer patients. | Hyuk-Chan Kwon Sung-Hyun Kim Sung Yong Oh Suee Lee Ji Hyun Lee Jin Seok Jang Min Chan Kim Ki Han Kim Su-Jin Kim Seong-Geun Kim Hyo-Jin Kim | 2012 | World Journal of Gastroenterology2012，18，34： | 9 |

| 4 | Antioxidative phytoceuticals to ameliorate pancreatitis in animal models: An answer from nature显示文摘Despite enthusiastic efforts directed at elucidating critical underlying mechanisms towards the identification of novel therapeutic targets for severe acute pancreatitis(SAP), the disease remains without a specific therapy to be executed within the first hours to days after onset of symptoms. Although earlier management for SAP should aim to either treat organ failure or reduce infectious complications, the current standard of care for the general management of AP in the first hours to days after onset of symptoms include intravenous fluid replacement, nutritional changes, and the use of analgesics with a close monitoring of vital signs. Furthermore, repeated evaluation of severity is very important, as the condition is particularly unstable in the early stages. In cases where biliary pancreatitis is accompanied by acute cholangitis or in cases where biliary stasis is suspected,an early endoscopic retrograde cholangiopancreatography is recommended.However,practice guidelines regarding the treatment of pancreatitis are suboptimal.In chronic pancreatitis,conservative management strategies include lifestyle modifications and dietary changes followed by analgesics and pancreatic enzyme supplementation.Recently,attention has been focused on phytoceuticals or antioxidants as agents that could surpass the limitations associated with currently available therapies.Because oxidative stress has been shown to play an important role in the pathogenesis of pancreatitis,antioxidants alone or combined with conventional therapy may improve oxidativestress-induced organ damage.Interest in phytoceuticals stems from their potential use as simple,accurate tools for pancreatitis prognostication that could replace older and more tedious methods.Therefore,the use of antioxidative nutrition or phytoceuticals may represent a new direction for clinical research in pancreatitis.In this review article,recent advances in the understanding of the pathogenesis of pancreatitis are discussed and the paradigm shift underway to develop phytoceuticals and antioxidants to treat it is introduced.Despite the promise of studies evaluating the effects of antioxidants/phytoceuticals in pancreatitis,translation to the clinic has thus far been disappointing.However,it is expected that continued research will provide solid evidence to justify the use of antioxidative phytoceuticals in the treatment of pancreatitis. | Jong-Min Park Sooyeon Lee Mi Kyung Chung Sung-Hun Kwon Eun-Hee Kim Kwang Hyun Ko Chang Il Kwon Ki Baik Hahm | 2014 | World Journal of Gastroenterology2014，20，44： | 5 |
| 5 | Effect of polyethylene glycol on electrochemically deposited trivalent chromium layers显示文摘The structural characteristics of the trivalent chromium deposits and their interfacial behavior in the plating solution with and without polyethylene glycol molecules were observed by using various electrochemical methods such as cyclic voltammetry,open circuit potential transition,electrochemical impedance spectroscopy,scanning electron microscopy and X-ray photoelectron spectrometry.It is shown that the polyethylene glycol molecules make the reductive current density lower in the trivalent chromium plating system and promote a hydrogen evolution reaction through their adsorption on the electrode surface.And the trivalent chromium layer formed from the polyethylene glycol-containing solution has somewhat higher density of cracks on its surface and results in a lower film resistance,lower polarization resistance,and higher capacitance in a corrosive atmosphere.It is also revealed that the formation of chromium carbide layer is facilitated in the presence of polyethylene glycol,which means easier electrochemical codeposition of chromium and carbon,not single chromium deposition. | Joo-Yul LEE Man KI M Sik-Chol KWON | 2009 | 中国有色金属学会会刊:英文版2009，19，4： | 5 |
| 6 | Stomach cancer screening and preventive behaviors in relatives of gastric cancer patients显示文摘AIM:To investigate gastric cancer screening and preventive behaviors among the relatives of patients with gastric cancer[i.e.,gastric cancer relatives(GCRs)].METHODS:We examined the Korean National Health and Nutrition Examination Survey 2005(KNHANESⅢ) database and compared the gastric cancer screening and preventive behaviors of GCRs(n=261)with those of non-GCRs(n=454)and controls without a family history of cancer(n=2842).RESULTS:The GCRs were more likely to undergo gastric cancer screening compared with the control group(39.2%vs 32.3%,adjusted odds ratio:1.43,CI:1.05-1.95),although the absolute screening rate was low.Dietary patterns and smoking rates did not differ significantly between the groups,and a high proportion of GCRs reported inappropriate dietary habits(i.e.,approximately 95%consumed excessive sodium,30% were deficient in vitamin C,and 85%were deficient in dietary fiber).CONCLUSION:The gastric cancer screening and preventive behaviors of GCRs have yet to be improved.To increase awareness among GCRs,systematic family education programs should be implemented. | Jung Min Kang Dong Wook Shin Young Min Kwon Sang Min Park Min Sun Park Jin Ho Park Ki Young Son Be Long Cho | 2011 | World Journal of Gastroenterology2011，17，30： | 4 |

| 10 | Factors associated with use of gastric cancer screening services in Korea显示文摘AIM: To identify the factors associated with participation in gastric cancer screening programs. METHODS: Using data from the Korea National Health and Nutrition Examination Survey 2005 (KNHANES Ⅲ), a nationwide health-related surveyin Korea, a cross-sectional study was performed to investigate the multiple factors associated with gastric cancer screening attendance among persons aged at least 40 years. The study population included 4593 individuals who completed a gastric cancer screening questionnaire and had no previous cancer history. Four groups ofindividual-level or environmental level covariates were considered as potential associated factors.RESULTS: Using KNHANES Ⅲdata, an estimated31.71% of Korean individuals aged at least 40 years adhered to gastric cancer screening recommendations. Subjects who graduated from elementary school[adjusted odds ratio (aOR), 1.66; 95% CI: 1.21-2.26], middle/high school (aOR, 1.38; 95% CI: 1.01-1.89), and university or higher (aOR, 1.64; 95% CI: 1.13-2.37) were more likely to undergo gastric cancer screening than those who received no formal education at all. The population with the highest income tertile had more attendance at gastric screening compared to those with the lowest income tertile (aOR, 1.36; 95% CI: 1.06-1.73). Gastric screening was also negatively associated with excessive alcohol consumption (aOR, 0.71; 95% CI: 0.53-0.96). A positive attitude to preventive medical evaluation was significantly associated with better participation in gastric cancer screening programs (aOR, 5.26; 95% CI: 4.35-6.35). CONCLUSION: Targeted interventions for vulnerable populations and public campaigns about preventive medical evaluation are needed to increase gastric cancer screening participation and reduce gastric cancer mortality. | Young Min Kwon Hyung Taek Lim Kiheon Lee Be Long Cho Min Sun Park Ki Young Son Sang Min Park | 2009 | World Journal of Gastroenterology2009，15，29： | 2 |

| 12 | Foldable and washable textile-based OLEDs with a multi-functional near-room-temperature encapsulation layer for smart e-textiles显示文摘Wearable electronic devices are being developed because of their wide potential applications and user convenience.Among them,wearable organic light emitting diodes(OLEDs)play an important role in visualizing the data signal processed in wearable electronics to humans.In this study,textile-based OLEDs were fabricated and their practical utility was demonstrated.The textilebased OLEDs exhibited a stable operating lifetime under ambient conditions,enough mechanical durability to endure the deformation by the movement of humans,and washability for maintaining its optoelectronic properties even in water condition such as rain,sweat,or washing.In this study,the main technology used to realize this textile-based OLED was multi-functional nearroom-temperature encapsulation.The outstanding impermeability of TiO_(2)film deposited at near-room-temperature was demonstrated.The internal residual stress in the encapsulation layer was controlled,and the device was capped by highly crosslinked hydrophobic polymer film,providing a highly impermeable,mechanically flexible,and waterproof encapsulation. | So Yeong Jeong Hye Rin Shim Yunha Na Ki Suk Kang Yongmin Jeon Seungyeop Choi Eun Gyo Jeong Yong Cheon Park Ha-Eun Cho Junwoo Lee Jeong Hyun Kwon Sung Gap Im Kyung Cheol Choi | 2021 | npj Flexible Electronics2021，5，1： | 2 |
| 13 | Preoperative serum carbohydrate antigen 19-9 levels predict early recurrence after the resection of early-stage pancreatic ductal adenocarcinoma显示文摘BACKGROUND Pancreatic ductal adenocarcinoma(PDAC)is a serious disease with a poor prognosis.Only a minority of patients undergo surgery due to the advanced stage of the disease,and patients with early-stage disease,who are expected to have a better prognosis,often experience recurrence.Thus,it is important to identify the risk factors for early recurrence and to develop an adequate treatment plan.AIM To evaluate the predictive factors associated with the early recurrence of earlystage PDAC.METHODS This study enrolled 407 patients with stage I PDAC undergoing upfront surgical resection between January 2000 and April 2016.Early recurrence was defined as a diagnosis of recurrence within 6 mo of surgery.The optimal cutoff values were determined by receiver operating characteristic(ROC)analyses.Univariate and multivariate analyses were performed to identify the risk factors for early recurrence.RESULTS Of the 407 patients,98 patients(24.1%)experienced early disease recurrence:26(26.5%)local and 72(73.5%)distant sites.In total,253(62.2%)patients received adjuvant chemotherapy.On ROC curve analysis,the optimal cutoff values for early recurrence were 70 U/mL and 2.85 cm for carbohydrate antigen 19-9(CA 19-9)levels and tumor size,respectively.Of the 181 patients with CA 19-9 level>70 U/mL,59(32.6%)had early recurrence,compared to 39(17.4%)of 226 patients with CA 19-9 level≤70 U/mL(P<0.001).Multivariate analysis revealed that CA 19-9 level>70 U/mL(P=0.006),tumor size>2.85 cm(P=0.004),poor differentiation(P=0.008),and non-adjuvant chemotherapy(P=0.025)were significant risk factors for early recurrence in early-stage PDAC.CONCLUSION Elevated CA 19-9 level(cutoff value>70 U/mL)can be a reliable predictive factor for early recurrence in early-stage PDAC.As adjuvant chemotherapy can prevent early recurrence,it should be recommended for patients susceptible to early recurrence. | Sarang Hong Ki Byung Song Dae Wook Hwang Jae Hoon Lee Woohyung Lee Eunsung Jun Jaewoo Kwon Yejong Park Seo Young Park Naru Kim Dakyum Shin Hyeyeon Kim Minkyu Sung Yunbeom Ryu Song Cheol Kim | 2021 | World Journal of Gastrointestinal Surgery2021，13，11： | 2 |
