| 1 | Nutritional risk index as a predictor of postoperative wound complications after gastrectomy显示文摘AIM:To investigate the correlation between the nutritional risk index (NRI) and postoperative wound complications.METHODS:From January 2008 through June 2008,669 patients who underwent curative gastrectomy for gastric cancer were included in a retrospective study.Medical records of consecutive patients were collected and analyzed to determine postoperative wound complication rates.The NRI was assessed on the fifth postoperative day and other possible risk factors for the incidence of wound complications were analyzed to identify the factors affecting postoperative wound complications.Patients with other postoperative complications were excluded from the study.RESULTS:On the 5th postoperative day,the NRI showed a malnutrition rate of 84.6% among postoperative patients.However,postoperative wound complications occurred in only 66/669 (9.86%) patients.Of the patients with wound complications,62/66 (94%) belonged to the malnourished group (NRI < 97.5),and 4/66 (6%) patients to the non-malnourished group (NRI ≥ 97.5).The only factor correlated with wound complications was the NRI on the 5th postoperative day (odds ratio of NRI ≥ 97.5 vs NRI < 97.5:0.653;95% confidence interval:0.326-0.974;P=0.014) according to univariate analysis as well as multivariate analysis.CONCLUSION:This study suggests that malnutrition immediately after surgery may play a significant role in the development of wound complications. | Cheong Ah Oh Dae Hoon Kim Seung Jong Oh Min Gew Choi Jae Hyung Noh Tae Sung Sohn Jae Moon Bae Sung Kim | 2012 | World Journal of Gastroenterology2012，18，7： | 25 |
| 2 | High-temperature Oxidation Behavior of Zircaloy-4 and Zirlo in Steam Ambient显示文摘The oxidation characteristics for Zircaloy-4 and Zirlo in the temperature range of 700-1200°C under steam supply condition were investigated by using a modified thermo-gravimetric analyzer.The specimens were oxidized for 3600 s at each temperature and then quenched in a furnace.The oxidation rate constants were measured from the weight gains to evaluate the oxidation behavior in Zircaloy-4 and Zirlo.The weight gain rates of Zirlo were lower than those of Zircaloy-4,leading to the low rate constants.The different oxidation behaviors between both cladding materials were considered to be due to the difference in their chemical compositions. | Hyung Hoon Kim Jun Ho Kim Jin Young Moon Ho Seong Lee Jeong Joo Kim Young Suck Chai | 2010 | Journal of Materials Science & Technology2010，26，9： | 7 |
| 3 | Transparent-cap-fitted colonoscopy shows higher performance with cecal intubation time in difficult cases显示文摘AIM:To investigate the efficacy of cap-fitted colonoscopy(CFC) with regard to cecal intubation time.METHODS:Two hundred and ninety-five patients undergoing screening colonoscopy at Gospel Hospital,Kosin University College of Medicine were enrolled in this randomized controlled trial between January and December 2010.Colonoscopies were conducted by a single endoscopist.Patient characteristics including age,sex,body mass index,history of abdominal surgery,quality of preparation,and the presence of diverticulosis were recorded.RESULTS:One hundred and fifty patients were allocated into a CFC group and 145 into a non-CFC(NCF) group.Cecal intubations were achieved in all patients.Cecal intubation time in the CFC group was significantly shorter than in the NCF group for specific conditions:age ≥ 60 years,prior abdominal surgery,and poor bowel preparation.The number of detected adenomas was higher in the CFC group than in the NCF group(P = 0.040).CONCLUSION:CFC facilitated shortening of the cecal intubation time in difficult cases,and was more sensitive for detecting adenomas than was NCF. | Hyung Hun Kim Seun Ja Park Moo In Park Won Moon Sung Eun Kim | 2012 | World Journal of Gastroenterology2012，18，16： | 7 |
| 4 | Effects of vagus nerve preservation and vagotomy on peptide YY and body weight after subtotal gastrectomy显示文摘AIM:To investigate the relationship between the function of vagus nerve and peptide YY 3-36 and ghrelin levels after subtotal gastrectomy.METHODS:We enrolled a total of 16 patients who underwent subtotal gastrectomy due to gastric cancer.All surgeries were performed by a single skilled surgeon.We measured peptide YY 3-36,ghrelin,leptin,insulin,growth hormone levels,and body weight immediately before and one month after surgery.RESULTS:Vagus nerve preservation group showed less body weight loss and less increase of peptide YY 3-36 compared with vagotomy group(-5.56 ± 2.24 kg vs-7.85 ± 1.57 kg,P = 0.037 and 0.06 ± 0.08 ng/mL vs 0.19 ± 0.12 ng/mL,P = 0.021,respectively).Moreover,patients with body weight loss of less than 10% exhibited reduced elevation of peptide YY 3-36 level,typically less than 20% [6(66.7%) vs 0(0.0%),P = 0.011,odd ratio = 3.333,95% confidence interval(1.293,8.591)].CONCLUSION:Vagus nerve preservation contributes to the maintenance of body weight after gastrectomy,and this phenomenon may be related to the suppressed activity of peptide YY 3-36. | Hyung Hun Kim Moo In Park Sang Ho Lee Hyun Yong Hwang Sung Eun Kim Seun Ja Park Won Moon | 2012 | World Journal of Gastroenterology2012，18，30： | 6 |
| 5 | Clinical implications of neutrophil-to-lymphocyte ratio and MDSC kinetics in gastric cancer patients treated with ramucirumab plus paclitaxel显示文摘Objective: We aimed to investigate the prognostic value of neutrophil-to-lymphocyte ratio(NLR) and myeloidderived suppressor cells(MDSCs) in gastric cancer patients treated with second-line ramucirumab plus paclitaxel.Methods: A total of 116 patients with advanced or metastatic gastric cancer who receive ramucirumab plus paclitaxel were prospectively enrolled. Fresh blood samples were collected before and after treatment, and flow cytometry was performed to assess the proportions of monocytic(m MDSCs) and granulocytic MDSCs(g MDSCs).Results: Median age was 58 years and 71(61.2%) patients were male. A baseline NLR≥2.94 was associated with significantly poorer progression-free survival(PFS) and overall survival(OS) vs. an NLR<2.94(P=0.011 and P=0.002, respectively). In multivariate analysis, an NLR≥2.94 was independently associated with poorer PFS[hazard ratio(HR)=1.58;95% confidence interval(95% CI): 1.01-2.49, P=0.046] and OS(HR=1.77;95% CI:1.04-3.04, P=0.036). While m MDSC counts did not significantly change following two cycles of therapy(P=0.530),g MDSC counts decreased significantly after two treatment cycles(P=0.025) but tended to increase in patients with progressive disease after two treatment cycles(P=0.098). A progressive increase in g MDSC counts(≥44%) was associated with a significantly shorter PFS and OS vs. a g MDSC count increase <44%(P=0.001 and P=0.003,respectively).Conclusions: The baseline NLR may help guide clinical decisions during ramucirumab plus paclitaxel therapy for gastric cancer. Our g MDSC kinetics data warrant further clinical validation and mechanistic investigation. | Hyung-Don Kim Min-Hee Ryu Sangsoon Yoon Young-Soon Na Meesun Moon Hyungeun Lee Hyung Geun Song Yoon-Koo Kang | 2020 | Chinese Journal of Cancer Research2020，32，5： | 4 |
| 6 | The role of vasoepididymostomy for treatment of obstructive azoospermia in the era of in vitro fertilization:a systematic review and meta-analysis显示文摘This study comprises a systematic review and meta-analysis of micmsurgical vasoepididymostomy outcomes in epididymal obstructive azoospermia.A comprehensive literature search was performed using Medline,Embase,and the Cochrane library that included all studies related to microsurgical vasoepididymostomy.Keywords included “vasoepididymostomy,”“epididymovasostomy,”“epididymal obstruction,”and “epididymis obstruction.”Event rate and risk ratio (RR)were estimated.Patency rate and pregnancy rate were investigated.The analysis comprised 1422 articles,including 42 observational studies with 2298 enrolled patients performed from November 1978 to January 2017.The overall mean patency rate was 64.1%(95%confidence interval [CI]:58.5%-69.3%;F=83.0%),and the overall mean pregnancy rate was 31.1%(95%CI:26.9%-35.7%;I^2=73.0%).We performed a meta-analysis comparing the patency rate of bilateral microsurgical vasoepididymostomy and unilateral microsurgical vasoepididymostomy and found an RR of 1.38%(95%CI: 1.21%-1.57%;P <0.00001).A comparison of the site of microsurgical vasoepididymostomy showed that caudal or corpus area was favorable for patency rate (RR =1.17%;95%CI: 1.01%-1.35%;P =0.04).Patients with motile sperm in epididymal fluid exhibited an RR of 1.53%(95%CI:1.11%-2.13%;P =0.01)with respect to patency rate. Microsurgical vasoepididymostomy is an effective treatment for epididymal obstructive azoospermia that can improve male fertility. We find that performing microsurgical vasoepididymostomy bilaterally,anastomosing a larger caudal area,and containing motile sperm in epididymis fluid can potentially achieve a superior patency rate. | Young Eun Yoon Hyung Ho Lee Sung Yul Park Hong Sang Moon Dong Suk Kim Seung-Hun Song Dae Keun Kim | 2019 | Asian Journal of Andrology2019，21，1： | 4 |
| 7 | Pancreatic hardness: Correlation of surgeon's palpation, durometer measurement and preoperative magnetic resonance imaging features显示文摘AIM To evaluate the correlation between subjective assessments of pancreatic hardness based on the palpation, objective measurements using a durometer, and magnetic resonance imaging(MRI) findings for assessing pancreatic hardness.METHODS Eighty-three patients undergoing pancreatectomies were enrolled. An experienced surgeon subjectively evaluated the pancreatic hardness in the surgical field by palpation. The pancreatic hardness was also objectivelyevaluated using a durometer. Preoperative MRI findings were evaluated by a radiologist in terms of the apparent diffusion coefficient(ADC) values, the relative signal intensity decrease(RSID) of the pancreatic parenchyma, and the diameter of the pancreatic parenchyma and duct. Durometer measurement results, ADC values, RSID, pancreatic duct and parenchyma diameters, and the ratio of the diameters of the duct and parenchyma were compared between pancreases judged to be soft or hard pancreas on the palpation. A correlation analysis was also performed between the durometer and MRI measurements.RESULTS The palpation assessment classified 44 patients as having a soft pancreas and 39 patients as having a hard pancreas. ADC values were significantly lower in the hard pancreas group. The ductal diameter and duct-to-pancreas ratio were significantly higher in the hard pancreas group. For durometer measurements, a correlation analysis showed a positive correlation with the ductal diameter and the duct-to-pancreas ratio and a negative correlation with ADC values. CONCLUSION Hard pancreases showed lower ADC values, a wider pancreatic duct diameter and a higher duct-to-pancreas ratio than soft pancreases. Additionally, the ADC values, diameter of the pancreatic duct and duct-to-pancreas ratio were closely correlated with the durometer results. | Tae Ho Hong Joon-Il Choi Michael Yong Park Sung Eun Rha Young Joon Lee Young Kyoung You Moon Hyung Choi | 2017 | World Journal of Gastroenterology2017，23，11： | 3 |
| 8 | Risk factors for metachronous gastric carcinoma development after endoscopic resection of gastric dysplasia: Retrospective, single-center study显示文摘AIM To determine the gastric adenocarcinoma(GAC)occurrence rate and related factors,we evaluated the follow-up results of patients confirmed to have gastric dysplasia after endoscopic resection(ER).METHODS We retrospectively analyzed the medical records,endoscopic examination records,endoscopic procedure records,and histological records of 667 cases from641 patients who were followed-up for at least 12mo,from among 1273 patients who were conformed to have gastric dysplasia after Endoscopic mucosal resection(EMR)or endoscopic submucosal dissection (ESD)of gastric mucosal lesions between January 2007and August 2013 at the Chungnam National University Hospital.RESULTS The mean follow-up period was 33.8 mo,and the median follow-up period was 29 mo(range:12-87).During the follow-up period,the occurrence of metachronous GAC was 4.0%(27/667).The mean and median interval periods between the occurrence of metachronous GAC and endoscopic treatment of gastric dysplasia were 36.3 and 34 mo,respectively(range:16-71).The factors related to metachronous GAC occurrence after ER for gastric dysplasia were male sex(5.3%vs 1.0%),open-type atrophic gastritis(9.5%vs3.4%),intestinal metaplasia(6.8%vs 2.4%),and highgrade dysplasia(HGD;8.4%vs 3.2%).Among them,male sex[OR:5.05(1.18-21.68),P=0.029],intestinal metaplasia[OR:2.78(1.24-6.23),P=0.013],and HGD[OR:2.70(1.16-6.26),P=0.021]were independent related factors in multivariate analysis.Furthermore,24of 27 GAC cases(88.9%)occurred at sites other than the previous resection sites,and 3(11.1%)occurred at the same site as the previous resection site.CONCLUSION Male sex,intestinal metaplasia,and HGD were significantly related to the occurrence of metachronous GAC after ER of gastric dysplasia,and most GACs occurred at sites other than the previous resection sites. | Hee Seok Moon Gee Young Yun Ju Seok Kim Hyuk Soo Eun Sun Hyung Kang Jae Kyu Sung Hyun Yong Jeong Kyu-Sang Song | 2017 | World Journal of Gastroenterology2017，23，24： | 3 |
| 9 | Predictors for difficult cecal insertion in colonoscopy: The impact of obesity indices显示文摘AIM To identify the factors influencing cecal insertion time(CIT) and to evaluate the effect of obesity indices on CIT. METHODS We retrospectively reviewed the data for participants who received both colonoscopy and abdominal computed tomography(CT) from February 2008 to May 2008 as part of a comprehensive health screening program. Age, gender, obesity indices [body mass index(BMI), waist-to-hip circumference ratio(WHR), waist circumference(WC), visceral adipose tissue(VAT)volume and subcutaneous adipose tissue(SAT) volume on abdominal CT], history of prior abdominal surgery, constipation, experience of the colonoscopist, quality of bowel preparation, diverticulosis and time required to reach the cecum were analyzed. CIT was categorized as longer than 10 min(prolonged CIT) and shorter than or equal to 10 min, and then the factors that required a CIT longer than 10 min were examined.RESULTS A total of 1678 participants were enrolled. The mean age was 50.42 ± 9.931 years and 60.3% were men. The mean BMI, WHR, WC, VAT volume and SAT volume were 23.92 ± 2.964 kg/m2, 0.90 ± 0.076, 86.95 ± 8.030 cm, 905.29 ± 475.220 cm3 and 1707.72 ± 576.550 cm3, respectively. The number of patients who underwent abdominal surgery was 268(16.0%). Colonoscopy was performed by an attending physician alone in 61.9% of cases and with the involvement of a fellow in 38.1% of cases. The median CIT was 7 min(range 2-56 min, IQR 5-10 min), and mean CIT was 8.58 ± 5.291 min. Being female, BMI, VAT volume and involvement of fellow were significantly associated with a prolonged CIT in univariable analysis. In multivariable analysis, being female(OR = 1.29, P = 0.047), lower BMI(< 23 kg/m2)(OR = 1.62, P = 0.004) or higher BMI(≥ 25 kg/m2)(OR = 1.80, P < 0.001), low VAT volume(< 500 cm3)(OR = 1.50, P = 0.013) and fellow involvement(OR = 1.73, P < 0.001) were significant predictors of prolonged CIT. In subgroup analyses for gender, lower BMI or higher BMI and fellow involvement were predictors for prolonged CIT in both genders. However, low VAT volume was associated with prolonged CIT in only women(OR = 1.54, P = 0.034).CONCLUSION Being female, having a lower or higher BMI than the normal range, a low VAT volume, and fellow involvement were predictors of a longer CIT. | Soo Yun Moon Byung Chang Kim Dae Kyung Sohn Kyung Su Han Bun Kim Chang Won Hong Bum Joon Park Kum Hei Ryu Ji Hyung Nam | 2017 | World Journal of Gastroenterology2017，23，13： | 3 |

| 11 | Aqueous levels of erythropoietin in acute retinal vein occlusion with macular edema显示文摘AIM:To investigate the aqueous erythropoietin(EPO)levels and associated factors in patients with acute retinal vein occlusion(RVO).METHODS:The aqueous EPO level was measured in patients with macular edema(ME)secondary to acute branched retinal vein occlusion(BRVO)or central retinal vein occlusion(CRVO).Aqueous fluid from cataract patients served as the control.We also evaluated whether aqueous level of EPO was associated with factors such as serum EPO level,non-perfusion area,central macular thickness(CMT),and arterio-venous(AV)transit timeRESULTS:Twenty-seven RVO patients(16 BRVO,11CRVO)and 9 control subjects were enrolled in the study.The aqueous EPO level(mU/mL)was higher in RVO(68.2±54.3)than that in the control subjects(12.9±5.9).More specifically,the aqueous EPO level was higher in CRVO(118.9±52.1)than that in BRVO(33.3±10.8).However,no differences were found in serum EPO levels among three groups.CMT in RVO patients had a positive correlation with the aqueous EPO level(r=0.66).Also,in terms of non-perfusion area,the aqueous EPO levels were more elevated in the ischemic subgroup than in the non-ischemic subgroup in both BRVO and CRVO.CONCLUSION:Aqueous EPO levels are elevated in patients with macular edema secondary to recent onset RVO.Patients with CRVO have higher EPO levels than those with BRVO.The aqueous EPO level in RVO has a positive correlation with CMT and is associated with non-perfusion area.These results suggest that the aqueous EPO level could be associated with retinal ischemia and may be involved in the pathogenesis of macular edema secondary to RVO. | Hyun Jin Shin Hyung Chan Kim Jun Woong Moon | 2014 | International Journal of Ophthalmology(English edition)2014，7，3： | 2 |
| 12 | Crystal Facet Engineering of TiO_(2) Nanostructures for Enhancing Photoelectrochemical Water Splitting with BiVO_(4) Nanodots显示文摘Although bismuth vanadate(BiVO4)has been promising as photoanode material for photoelectrochemical water splitting,its charge recombination issue by short charge diffusion length has led to various studies about heterostructure photoanodes.As a hole blocking layer of BiVO4,titanium dioxide(TiO_(2)) has been considered unsuitable because of its relatively positive valence band edge and low electrical conductivity.Herein,a crystal facet engineering of TiO_(2) nanostructures is proposed to control band structures for the hole blocking layer of BiVO4 nanodots.We design two types of TiO_(2) nanostructures,which are nanorods(NRs)and nanoflowers(NFs)with different(001)and(110)crystal facets,respectively,and fabricate BiVO4/TiO_(2) heterostructure photoanodes.The BiVO4/TiO_(2) NFs showed 4.8 times higher photocurrent density than the BiVO4/TiO_(2) NRs.Transient decay time analysis and time-resolved photoluminescence reveal the enhancement is attributed to the reduced charge recombination,which is originated from the formation of type II band alignment between BiVO4 nanodots and TiO_(2) NFs.This work provides not only new insights into the interplay between crystal facets and band structures but also important steps for the design of highly efficient photoelectrodes. | Mi Gyoung Lee Jin Wook Yang Hoonkee Park Cheon Woo Moon Dinsefa M.Andoshe Jongseong Park Chang‑Ki Moon Tae Hyung Lee Kyoung Soon Choi Woo Seok Cheon Jang‑Joo Kim Ho Won Jang | 2022 | Nano-Micro Letters2022，14，3： | 2 |
