2Toothpick impaction with sigmoid colon pseudodiverticulum formation successfully treated with colonoscopy显示文摘Foreign bodies in the colon are encountered with increasing frequency, but only sporadic reports concerning their management have appeared in the literature. While most ingested foreign bodies usually pass through the gastrointestinal tract uneventfully, sharp foreign bodies such as toothpicks infrequently cause intestinal perforation and may even result in death. We report our experience with a patient with a sigmoid colon pseudodiverticulum formation, a complication of accidental ingestion of a toothpick that was diagnosed and successfully managed colonoscopically.Youn Son Chung Yong Woo Chung Sun You Moon Su Mi Yoon Min-Jeong Kim Kyoung Oh Kim Cheol Hee Park Taeho Hahn Kyo-Sang Yoo Sang Hoon Park Jong Hyeok Kim Choong Kee Park 2008World Journal of Gastroenterology2008,14,6:10

5Gender differences in clinical outcomes of acute myocardial infarction undergoing percutaneous coronary intervention: insights from the KAMIR-NIH Registry显示文摘Background There are numerous but conflicting data regarding gender differences in outcomes following percutaneous coronary intervention(PCI). Furthermore, gender differences in clinical outcomes with acute myocardial infarction(AMI) following PCI in Asian population remain uncertain because of the under-representation of Asian in previous trials. Methods A total of 13,104 AMI patients from Korea Acute Myocardial Infarction Registry-National Institute of Health(KAMIR-NIH) between November 2011 and December 2015 were classified into male(n = 8021, 75.9%) and female(n = 2547, 24.1%). We compared the demographic, clinical and angiographic characteristics, 30-days and 1-year major adverse cardiac and cerebrovascular events(MACCE) in women with those in men after AMI by using propensity score(PS) matching. Results Compared with men, women were older, had more comorbidities and more often presented with non-ST segment elevation myocardial infarction(NSTEMI) and reduced left ventricular systolic function. Over the median follow-up of 363 days, gender differences in both 30-days and 1-year MACCE as well as thrombolysis in myocardial infarction minor bleeding risk were not observed in the PS matched population(30-days MACCE: 5.3% vs. 4.7%, log-rank P = 0.494, HR = 1.126, 95% CI: 0.800-1.585;1-year MACCE: 9.3% vs. 9.0%, log-rank P = 0.803, HR = 1.032, 95% CI: 0.802-1.328;TIMI minor bleeding: 4.9% vs. 3.9%, log-rank P = 0.215, HR = 1.255, 95% CI: 0.869-1.814). Conclusions Among Korean AMI population undergoing contemporary PCI, women, as compared with men, had different clinical and angiographic characteristics but showed similar 30-days and 1-year clinical outcomes. The risk of bleeding after PCI was comparable between men and women during one-year follow up.Myunhee Lee Dae-Won Kim Mahn-Won Park Kyusup Lee Kiyuk Chang Wook Sung Chung Tae Hoon Ahn Myung Ho Jeong Seung-Woon Rha Hyo-Soo Kim Hyeon Cheol Gwon In Whan Seong Kyung Kuk Hwang Shung Chull Chae Kwon-Bae Kim Young Jo Kim Kwang Soo Cha Seok Kyu Oh Jei Keon Chae Ji-Hoon Jung KAMIR-NIH registry investigators 2020Journal of Geriatric Cardiology2020,17,11:3
6Gallbladder lymphangioma:A case report and review of the literature显示文摘Lymphangiomas are rare, benign tumors of the lymphatic system, usually present in children aged 5 years and younger. Because they are asymptomatic until the mass enlarges to cause symptoms, most lymphangiomas are diagnosed at adulthood incidentally. We experienced a case of a 60-year-old man diagnosed with a cystic lymphangioma of the gallbladder, which was successfully resected without any complication. Magnetic resonance imaging and magnetic resonance cholangiopancreatography were very helpful for the diagnosis of the cystic lesion around the gallbladder as were ultrasonography and computed tomography scan. These showed a multi-lobulated cystic mass with intact cystic duct and bile duct in the gallbladder fossa. The patient underwent an open cholecystectomy and the histological findings were consistent with a cystic lymphangioma of the gallbladder. We here report the case of cystic lymphangioma of the gallbladder with a review of the literature.Jwa-Kyung Kim Kyo-Sang Yoo Joon Ho Moon Kwang Hyuk Park Yong Woo Chung Kyoung Oh Kim Cheol Hee Park Taeho Hahn Sang Hoon Park Jong Hyeok Kim Jang Yeong Jeon Min Jung Kim Kwang Seon Min Department of Pathology Hallym University College of Medicine Anyang Korea Choong Kee Park 2007World Journal of Gastroenterology2007,13,2:3

8Calcium channel blocker monotherapy versus combination with reninangiotensin system inhibitors on the development of new-onset diabetes mellitus in hypertensive Korean patients显示文摘Background In real practice, two or more antihypertensive drugs are needed to achieve target blood pressure. We investigated the comparative beneficial actions of combination therapy of renin-angiotensin system inhibitors (RASI), with calcium channel blockers (CCB) over CCB monotherapy on the development of new-onset diabetes mellitus (NODM) in Korean patients during four-year follow-up periods. Methods A total of 3208 consecutive hypertensive patients without a history of diabetes mellitus who had been prescribed CCB were retrospectively enrolled from January 2004 to December 2012. These patients were divided into the two groups according to the additional use of RASI (the RASI group, n = 1221 and the no RASI group, n = 1987). Primary endpoint was NODM, defined as a fasting blood glucose ≥ 126 mg/dL or hemoglobin A1c ≥ 6.5%. Secondary endpoint was major adverse cardiac events (MACE) defined as total death, myocardial infarction (MI) and percutaneous coronary intervention (PCI). Results After propensity score-matched (PSM) analysis, two propensity- matched groups (939 pairs, n = 1878, C-statistic = 0.743) were generated. The incidences of NODM (HR = 1.009, 95% CI: 0.700–1.452, P = 0.962), MACE (HR = 0.877, 95% CI: 0.544–1.413, P = 0.589), total death, MI, PCI were similar between the two groups after PSM during four years. Conclusions The use of RASI in addition to CCB showed comparable incidences of NODM and MACE compared to CCB monotherapy in non-diabetic hypertensive Korean patients during four-year follow-up period. However, large-scaled randomized controlled clinical trials will be required for a more definitive conclusion.Yong Hoon Kim Ae-Young Her Seung-Woon Rha Byoung Geol Choi Se Yeon Choi Jae Kyeong Byun Yoonjee Park Dong Oh Kang Won Young Jang Woohyeun Kim Woong Gil Choi Tae Soo Kang Jihun Ahn Sang-Ho Park Ji Young Park Min-Ho Lee Cheol Ung Choi Chang Gyu Park Hong Seog Seo 2019Journal of Geriatric Cardiology2019,16,6:3
9RGD peptide and graphene oxide co-functionalized PLGA nanofiber scaffolds for vascular tissue engineering显示文摘In recent years,much research has been suggested and examined for the development of tissue engineering scaffolds to promote cellular behaviors.In our study,RGD peptide and graphene oxide(GO)co-functionalized poly(lactide-co-glycolide,PLGA)(RGD-GO-PLGA)nanofiber mats were fabricated via electrospinning,and their physicochemical and thermal properties were characterized to explore their potential as biofunctional scaffolds for vascular tissue engineering.Scanning electron microscopy images revealed that the RGD-GO-PLGA nanofiber mats were readily fabricated and composed of randomoriented electrospun nanofibers with average diameter of 558nm.The successful co-functionalization of RGD peptide and GO into the PLGA nanofibers was confirmed by Fourier-transform infrared spectroscopic analysis.Moreover,the surface hydrophilicity of the nanofiber mats was markedly increased by co-functionalizing with RGD peptide and GO.It was found that the mats were thermally stable under the cell culture condition.Furthermore,the initial attachment and proliferation of primarily cultured vascular smoothmuscle cells(VSMCs)on the RGD-GO-PLGA nanofibermats were evaluated.It was revealed that the RGD-GO-PLGA nanofibermats can effectively promote the growth of VSMCs.In conclusion,our findings suggest that the RGD-GO-PLGA nanofiber mats can be promising candidates for tissue engineering scaffolds effective for the regeneration of vascular smooth muscle.Yong Cheol Shin Jeonghyo Kim Sung Eun Kim Su-Jin Song SuckWon Hong Jin-Woo Oh Jaebeom Lee Jong-Chul Park Suong-Hyu Hyon Dong-Wook Han 2017Regenerative Biomaterials2017,4,3:3

11Sex-based differences in histology,staging,and prognosis among 2983 gastric cancer surgery patients显示文摘BACKGROUND Few studies have been conducted on sex differences in the incidence, pathophysiology, and prognosis of gastric cancer(GC).AIM To analyze the differences in GC characteristics according to sex in patients who underwent surgical treatment for GC.METHODS A total of 2983 patients diagnosed with gastric adenocarcinoma who received surgical treatment at the Seoul National University Bundang Hospital between 2003 and 2017 were included.Baseline clinicopathological characteristics, histologic type of GC, overall and GC-specific survival rates, and associated risk factors were analyzed.RESULTS Among the 2983 patients, 2005(67.2%) and 978(32.8%) were males and females, respectively.The average age of the female group(59.36 years) was significantly younger than that of the male group(61.66 years;P < 0.001).Cancer of the gastric body(P < 0.001) and diffuse-type histology(P < 0.001) were more common in females than in males.This trend was more prominent in females younger than 60 years of age, with a significantly higher proportion of diffuse-type cancer than in the male group.Regardless of sex, diffuse-type GC was more common in younger patients, and the proportion of intestinal-type GC increased with age.The overall survival rate was significantly higher in females(P < 0.001).However, this difference disappeared for GC-specific survival(P = 0.168), except for the poor GC-specific survival rate in advanced-stage cancer(stage Ⅲ or above) in females(P = 0.045).The risk factors for GC-related mortality were older age, upper location of GC, and diffuse-or mixed-type histology.In terms of comorbidities, more males died from diseases other than GC, including other malignancies such as lung cancer, hepatocellular carcinoma, and pancreatic cancer, and respiratory diseases such as interstitial lung disease and chronic obstructive pulmonary disease, while there were relatively more cardiovascular or cerebrovascular deaths in females.CONCLUSION Sex-based differences in GC were observed in clinicopathological features, including age at diagnosis, tumor location, histologic type, survival rate, and comorbidities.Yonghoon Choi Nayoung Kim Ki Wook Kim Hyeong Ho Jo Jaehyung Park Hyuk Yoon Cheol Min Shin Young Soo Park Dong Ho Lee Hyeon Jeong Oh Hye Seung Lee Young Suk Park Sang-Hoon Ahn Yun-Suhk Suh Do Joong Park Hyung-Ho Kim Ji-Won Kim Jin Won Kim Keun-Wook Lee Won Chang Ji HoonPark Yoon Jin Lee Kyoung Ho Lee Young Hoon Kim 2022World Journal of Gastroenterology2022,28,9:2

15Five-year clinical outcomes of first-generation versus second-generation drug-eluting stents following coronary chronic total occlusion intervention显示文摘Background There are limited data comparing long-term clinical outcomes between first-generation (1G) and second-generation (2G) drug-eluting stents (DESs) in patients who underwent successful percutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO) lesion. Methods A total of 840 consecutive patients who underwent PCI with DESs for CTO lesion from January 2004 to November 2015 were enrolled. Finally, a total of 324 eligible CTO patients received 1G-DES (Paclitaxel-eluting stent or Sirolimus-eluting stent, n = 157) or 2G-DES (Zotarolimus-eluting stent or Everolimus-eluting stent, n = 167) were enrolled. The clinical endpoint was the occurrence of major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction (re-MI), total repeat revascularization [target lesion revascularization (TLR), target vessel revascularization (TVR), and non-TVR]. We investigated the 5-year major clinical outcomes between 1G-DES and 2G-DES in patient who underwent successful CTO PCI. Results After propensity score matched (PSM) analysis, two well-balanced groups (111 pairs, n = 222, C-statistic = 0.718) were generated. Up to the 5-year follow-up period, the cumulative incidence of all-cause death, re-MI, TLR, TVR and non-TVR were not significantly different between the two groups. Finally, MACE was also similar between the two groups (HR = 1.557, 95% CI: 0.820–2.959, P = 0.176) after PSM. Conclusions In this study, 2G-DES was not associated with reduced long-term MACE compared with 1G-DES following successful CTO revascularization up to five years.Yong Hoon Kim Ae-Young Her Seung-Woon Rha Byoung Geol Choi Se Yeon Choi Jae Kyeong Byun Yoonjee Park Dong Oh Kang Won Young Jang Woohyeun Kim Ju Yeol Baek Woong Gil Choi Tae Soo Kang Jihun Ahn Sang-Ho Park Ji Young Park Min-Ho Lee Cheol Ung Choi Chang Gyu Park Hong Seog Seo 2019Journal of Geriatric Cardiology2019,16,8:1

20Direct Synthesis of Molybdenum Phosphide Nanorods on Silicon Using Graphene at the Heterointerface for Efficient Photoelectrochemical Water Reduction显示文摘Transition metal phosphides(TMPs)and transition metal dichalcogenides(TMDs)have been widely investigated as photoelectrochemical(PEC)catalysts for hydrogen evolution reaction(HER).Using high-temperature processes to get crystallized compounds with large-area uniformity,it is still challenging to directly synthesize these catalysts on silicon photocathodes due to chemical incompatibility at the heterointerface.Here,a graphene interlayer is applied between p-Si and MoP nanorods to enable fully engineered interfaces without forming a metallic secondary compound that absorbs a parasitic light and provides an inefficient electron path for hydrogen evolution.Furthermore,the graphene facilitates the photogenerated electrons to rapidly transfer by creating Mo-O-C covalent bondings and energetically favorable band bending.With a bridging role of graphene,numerous active sites and anti-reflectance of MoP nanorods lead to significantly improved PEC-HER performance with a high photocurrent density of 21.8 mA cm−2 at 0 V versus RHE and high stability.Besides,low dependence on pH and temperature is observed with MoP nanorods incorporated photocathodes,which is desirable for practical use as a part of PEC cells.These results indicate that the direct synthesis of TMPs and TMDs enabled by graphene interlayer is a new promising way to fabricate Si-based photocathodes with high-quality interfaces and superior HER performance.Sang Eon Jun Seokhoon Choi Shinyoung Choi Tae Hyung Lee Changyeon Kim Jin Wook Yang Woon‑Oh Choe In‑Hyuk Im Cheol‑Joo Kim Ho Won Jang 2021Nano-Micro Letters2021,13,5:1
