| 2 | Minimally invasive radical pancreatectomy for left-sided pancreatic cancer:Current status and future perspectives显示文摘Minimally invasive distal pancreatectomy with splenectomy has been regarded as a safe and effective treatment for benign and borderline malignant pancreatic lesions.However,its application for left-sided pancreatic cancer is still being debated.The clinical evidence for radical antegrade modular pancreatosplenectomy(RAMPS)-based minimally invasive approaches for leftsided pancreatic cancer was reviewed.Potential indications and surgical concepts for minimally invasive RAMPS were suggested.Despite the limited clinical evidence for minimally invasive distal pancreatectomy in left-sided pancreatic cancer,the currently available clinical evidence supports the use of laparoscopic distal pancreatectomy under oncologic principles in wellselected left sided pancreatic cancers.A pancreasconfined tumor with an intact fascia layer between the pancreas and left adrenal gland/kidney positioned more than 1 or 2 cm away from the celiac axis is thought to constitute a good condition for the use of margin-negative minimally invasive RAMPS.The use of minimally invasive(laparoscopic or robotic)anterior RAMPS is feasible and safe for margin-negative resection in wellselected left-sided pancreatic cancer.The oncologic feasibility of the procedure remains to be determined;however,the currently available interim results indicate that even oncologic outcomes will not be inferior to those of open radical distal pancreatosplenectomy. | Chang Moo Kang Sung Hwan Lee Woo Jung Lee | 2014 | World Journal of Gastroenterology2014，20，9： | 21 |
| 3 | Mitochondria-targeting drug conjugates for cytotoxic, anti-oxidizing and sensing purposes:current strategies and future perspectives显示文摘mitochondrial-targeting moieties to anticancer drugs, antioxidants and sensor molecules. Among them, the most widely applied mitochondrial targeting moiety is triphenylphosphonium(TPP), which is a delocalized cationic lipid that readily accumulates and penetrates through the mitochondrial membrane due to the highly negative mitochondrial membrane potential. Other moieties, including short peptides,dequalinium, guanidine, rhodamine, and F16, are also known to be promising mitochondrial targeting agents. Direct conjugation of mitochondrial targeting moieties to anticancer drugs, antioxidants and sensors results in increased cytotoxicity, anti-oxidizing activity and sensing activity, respectively,compared with their non-targeting counterparts, especially in drug-resistant cells. Although many mitochondria-targeted anticancer drug conjugates have been investigated in vitro and in vivo, further clinical studies are still needed. On the other hand, several mitochondria-targeting antioxidants have been analyzed in clinical phases I, II and III trials, and one conjugate has been approved for treating eye disease in Russia. There are numerous ongoing studies of mitochondria-targeted sensors. | Gantumur Battogtokh Yeon Su Choi Dong Seop Kang Sang Jun Park Min Suk Shim Kang Moo Huh Yong-Yeon Cho Joo Young Lee Hye Suk Lee Han Chang Kang | 2018 | Acta Pharmaceutica Sinica B2018，8，6： | 17 |
| 4 | Prognostic significance of the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients with stage Ⅲ and Ⅳcolorectal cancer显示文摘AIM To evaluate the prognostic value of the neutrophil-tolymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) in patients with colorectal cancer(CRC).METHODS Between April 1996 and December 2010, medical records from a total of 1868 patients with CRC were retrospectively reviewed. The values of simple inflammatory markers including NLR and PLR in predicting the long-term outcomes of these patients were evaluated using Kaplan-Meier curves and Cox regression models.RESULTS The median follow-up duration was 46 mo(interquartile range, 22-73). The estimation of NLR and PLR was based on the time of diagnosis. In multivariate Cox regression analysis, high NLR (≥ 3.0) and high PLR(≥ 160) were independent risk factors predicting poor long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. However, high NLR and high PLR were not prognostic factors in patients with stage Ⅰ and Ⅱ CRC.CONCLUSION In this study, we identified that high NLR (≥ 3.0) and high PLR (≥ 160) are useful prognostic factors to predict long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. | Jae Hyun Kim Jun Yeop Lee Hae Koo Kim Jin Wook Lee Sung Gyu Jung Kyoungwon Jung Sung Eun Kim Won Moon Moo In Park Seun Ja Park | 2017 | World Journal of Gastroenterology2017，23，3： | 16 |
| 5 | Prevalence of clonorchiasis in patients with gastrointestinal disease: A Korean nationwide multicenter survey显示文摘AIM: To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea.METHODS: Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire.RESULTS: Of 3080 patients with gastrointestinal diseases, 396 (12.9%) had clonorchiasis and 1140 patients (37.2%) had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 (20.9%) patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than non-infected patients [34/396 (8.6%) vs 145/2684 (5.4%), P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation (P = 0.008). Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis.CONCLUSION: Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite. | Ho Gak Kim Jimin Han Myung-Hwan Kim Kyu Hyun Cho Im Hee Shin Gwang Ha Kim Jae Seon Kim Jin Bong Kim Tae Nyeun Kim Tae Hyeon Kim Tae Hyo Kim Jae Woo Kim Ji Kon Ryu Young-Soo Moon Jong Ho Moon Sung Jae Park Chan Guk Park Sung-Jo Bang Chang Heon Yang Kyo-Sang Yoo Byung Moo Yoo Kyu Taek Lee Dong Ki Lee Byung Seok Lee Sang Soo Lee Seung Ok Lee Woo Jin Lee Chang Min Cho Young-Eun Joo Gab Jin Cheon Young Woo Choi Jae Bok Chung Yong Bum Yoon | 2009 | World Journal of Gastroenterology2009，15，1： | 15 |
| 6 | Endoscopic papillary large balloon dilation for the removal of bile duct stones显示文摘Endoscopic papillary large balloon dilation(EPLBD)with endoscopic sphincterotomy(EST)has been widely used as the alternative to EST along with endoscopic mechanical lithotripsy(EML)for the removal of large or difficult bile duct stones.Furthermore,EPLBD without EST was recently introduced as its simplified alternative technique.Thus,we systematically searched PubMed,Medline,the Cochrane Library and EMBASE,and analyzed all gathered data of EPLBD with and without EST,respectively,by using a single standardized definition,reviewing relevant literatures,published between 2003and June 2013,where it was performed with largediameter balloons(12-20 mm).The outcomes,including the initial success rate,the rate of needs for EML,and the overall success rate,and adverse events were assessed in each and compared between both of two procedures:'EPLBD with EST'and'EPLBD without EST'.A total of 2511 procedures from 30 published articles were included in EPLBD with EST,while a total of413 procedures from 3 published articles were included in EPLBD without EST.In the results of outcomes,the overall success rate was 96.5%in EPLBD with EST and97.2%in EPLBD without EST,showing no significant difference between both of them.The initial success rate(84.0%vs 76.2%,P<0.001)and the success rate of EPLBD without EML(83.2%vs 76.7%,P=0.001)was significantly higher,while the rate of use of EML was significantly lower(14.1%vs 21.6%,P<0.001),in EPLBD with EST.The rate of overall adverse events,pancreatitis,bleeding,perforation,other adverse events,surgery for adverse events,and fatal adverse events were 8.3%,2.4%,3.6%,0.6%,1.7%,0.2%and 0.2%in EPLBD with EST and 7.0%,3.9%,1.9%,0.5%,0.7%,0%and 0%in EPLBD without EST,respectively,showing no significant difference between both of them.In conclusion,recent accumulated results of EPLBD with or even without EST suggest that it is a safe and effective procedure for the removal of large or difficult bile duct stones without any additional risk of severe adverse events,when performed under appropriate guidelines. | Jin Hong Kim Min Jae Yang Jae Chul Hwang Byung Moo Yoo | 2013 | World Journal of Gastroenterology2013，19，46： | 12 |
| 7 | Removal of formaldehyde over Mn_xCe_(1- x)O_2 catalysts: Thermal catalytic oxidation versus ozone catalytic oxidation显示文摘MnxCe1-xO2(x:0.3–0.9)prepared by Pechini method was used as a catalyst for the thermal catalytic oxidation of formaldehyde(HCHO).At x=0.3 and 0.5,most of the manganese was incorporated in the fluorite structure of Ce O2to form a solid solution.The catalytic activity was best at x=0.5,at which the temperature of 100%removal rate is the lowest(270°C).The temperature for 100%removal of HCHO oxidation is reduced by approximately 40°C by loading 5 wt.%Cu Oxinto Mn0.5Ce0.5O2.With ozone catalytic oxidation,HCHO(61 ppm)in gas stream was completely oxidized by adding 506 ppm O3over Mn0.5Ce0.5O2catalyst with a GHSV(gas hourly space velocity)of 10,000 hr-1at 25°C.The effect of the molar ratio of O3to HCHO was also investigated.As O3/HCHO ratio was increased from 3 to 8,the removal efficiency of HCHO was increased from 83.3%to 100%.With O3/HCHO ratio of 8,the mineralization efficiency of HCHO to CO2was 86.1%.At 25°C,the p-type oxide semiconductor(Mn0.5Ce0.5O2)exhibited an excellent ozone decomposition efficiency of 99.2%,which significantly exceeded that of n-type oxide semiconductors such as Ti O2,which had a low ozone decomposition efficiency(9.81%).At a GHSV of 10,000 hr-1,[O3]/[HCHO]=3 and temperature of 25°C,a high HCHO removal efficiency(≥81.2%)was maintained throughout the durability test of 80 hr,indicating the long-term stability of the catalyst for HCHO removal. | Jia Wei Li Kuan Lun Pan Sheng Jen Yu Shaw Yi Yan Moo Been Chang | 2014 | Journal of Environmental Sciences2014，26，12： | 9 |
| 8 | Removal of VOCs from gas streams with double perovskite-type catalysts显示文摘Double perovskite-type catalysts including La2 CoMnO_6 and La_2 CuMnO_6 are first evaluated for the effectiveness in removing volatile organic compounds(VOCs), and single perovskites(La CoO_3, LaMnO_3, and La Cu O3) are also tested for comparison. All perovskites are tested with the gas hourly space velocity(GHSV) of 30,000 hr^(-1), and the temperature range of100–600°C for C_7H_8 removal. Experimental results indicate that double perovskites have better activity if compared with single perovskites. Especially, toluene(C_7H_8) can be completely oxidized to CO_2 at 300°C as La2 Co MnO_6 is applied. Characterization of catalysts indicates that double perovskites own unique surface properties and are of higher amounts of lattice oxygen,leading to higher activity. Additionally, apparent activation energy of 68 k J/mol is calculated using Mars-van Krevelen model for C7 H8 oxidation with La2 Co Mn O6 as catalyst. For durability test, both La2 Co Mn O6 and La_2 CuMnO_6 maintain high C7 H8 removal efficiencies of 100% and98%, respectively, at 300°C and 30,000 hr^(-1), and they also show good resistance to CO_2(5%) and H2 O(g)(5%) of the gas streams tested. For various VOCs including isopropyl alcohol(C_3H_8 O),ethanal(C_2H_4O), and ethylene(C_2H_4) tested, as high as 100% efficiency could be achieved with double perovskite-type catalysts operated at 300–350°C, indicating that double perovskites are promising catalysts for VOCs removal. | Kuan Lun Pan Guan Ting Pan Siewhui Chong Moo Been Chang | 2018 | Journal of Environmental Sciences2018，30，7： | 8 |
| 9 | 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 |
| 10 | Inhibitory activities of microalgal fucoxanthin againstα-amylase,α-glucosidase, and glucose oxidase in 3T3-L1cells linked to type 2 diabetes显示文摘Postprandial hyperglycemia is an early indication of type 2 diabetes and the target of many anti-diabetic and anti-obesity studies.α-Glucosidase and α-amylase are the crucial factors in regulating starch digestion and glucose absorption,making them key targets for many studies to treat postprandial hyperglycemia.We studied the inhibitory activities of microalgal fucoxanthin against rat-intestinalα-glucosidase and pancreaticα-amylase along with the antidiabetic eff ect to induce diff erentiation in 3T3-L1 pre-adipocytes using Oil Red-O staining.Fucoxanthin displayed strong hindrance activities towardα-amylase in a concentration-dependent manner,with an IC50 value of 0.68mmol/L,whereas weak inhibitory activity against α-glucosidase,with an IC 50 value of 4.75 mmol/L.Fucoxanthin also considerably elevated glucose oxidase activity in 3T3-L1 cells by 31.3%at 5μmol/L.During adipocyte differentiation,fucoxanthin showed lipid accumulation in 3T3-L1 cells with no cytotoxicity up to 20μmol/L.However,fucoxanthin had no inhibitory activity on glucose-6-phosphate dehydrogenase.These results suggest that fucoxanthin might be useful for the prevention of obesity or diabetes by inhibiting carbohydrate-hydrolyzing enzymes and lipid accumulation and be utilized as an ingredient for a functional food or dietary supplement. | KAWEE-AI Arthitaya KIM Aaron Taehwan KIM Sang Moo | 2019 | Journal of Oceanology and Limnology2019，37，3： | 7 |
| 11 | Optimization of Culturing Condition and Medium Composition for the Production of Alginate Lyase by a Marine Vibrio sp. YKW-34显示文摘Carbohydrases secreted by marine Vibrio sp. YKW-34 with strong Laminaria cell wall degrading ability were screened, and among them alginate lyase was found to be dominant. The effects of medium composition and culturing condition on the produc- tion of alginate lyase by marine Vibrio sp. YKW-34 in flask were investigated in this study. In the culture medium of marine broth, no alginate lyase was produced. The activity of the alginate lyase, after being induced, reached 5 UmL–1. The best inoculum volume and inoculum age were 10% and 12 h, respectively. The optimal temperature for alginate lyase production was 25℃. The fermentation medium was composed of 0.5% of Laminaria powder and 0.2% of KNO3 with an initial acidity of pH 8.0. Alginate could induce alginate lyase production but not as efficiently as Laminaria powder did. The addition of fucoidan, cellulose and glucose had nega- tive effect on the alginate lyase production. Other kinds of nitrogen sources, such as yeast extract, beef extract and peptone, had posi- tive effect on the growth of the microorganism and negative effect on alginate lyase production. In addition, the time course of algi- nate lyase production under the optimized condition was described. The optimal harvest time was 48 h. | FU Xiaoting LIN Hong KIM Sang Moo | 2008 | Journal of Ocean University of China2008，7，1： | 6 |
| 12 | 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 |
| 13 | Catalytic removal of phenol from gas streams by perovskite-type catalysts显示文摘Three perovskite-type catalysts prepared by citric acid method are applied to remove phenol from gas streams with the total flow rate of 300 mL/min, corresponding to a GHSV of10,000/hr. LaMnO_3 catalyst is first prepared and further partially substituted with Sr and Cu to prepare La_(0.8)Sr_(0.2)MnO_3 and La_(0.8)Sr_(0.2)Mn_(0.8)Cu_(0.2)O_3, and catalytic activities and fundamental characteristics of these three catalysts are compared. The results show that phenol removal efficiency achieved with La_(0.8)Sr_(0.2)Mn_(0.8)Cu_(0.2)O_3 reaches 100% with the operating temperature of 200°C and the rate of mineralization at 300°C is up to 100%, while the phenol removal efficiencies achieved with La_(0.8)Sr_(0.2)MnO_3 and LaMnO_3 are up to 100% with the operating temperature of 300°C and 400°C, respectively. X-ray photoelectron spectroscopy(XPS) analysis shows that the addition of Sr and Cu increases the lattice oxygen of La_(0.8)Sr_(0.2)Mn_(0.8)Cu_(0.2)O_3, and further increases mobility or availability of lattice oxygen. The results indicate that La_(0.8)Sr_(0.2)Mn_(0.8)Cu_(0.2)O_3 has the best activity for phenol removal among three catalysts prepared and the catalytic activity of phenol oxidation is enhanced by the introduction of Sr and Cu into LaMnO_3. Apparent activation energy of 48 k J/mol is calculated by Mars–Van Krevelen Model for phenol oxidation with La_(0.8)Sr_(0.2)Mn_(0.8)Cu_(0.2)O_3 as catalyst. | Dai Ling Chen Kuan Lun Pan Moo Been Chang | 2017 | Journal of Environmental Sciences2017，29，6： | 5 |
| 14 | Role of inflammasome regulation on immune modulators显示文摘Inflammatory responses are essential in eliminating harmful substrates from damaged tissue and inducing recovery.Several cytokines participate in and facilitate this response. Certain cytokines such as interleukin(IL)-1β and IL-18 are initially produced in precursor form in response to toll-like receptor(TLR) ligands and undergo maturation by inflammasomes, which are cytosolic multi-protein complexes containing nucleotide-binding oligomerization domain(NOD)-containing protein 2-like receptors(NLRs). Immune modulators targeting inflammasomes have been investigated to control inflammatory diseases such as metabolic syndrome. However, most immune modulators possessing anti-inflammasome properties attenuate production of other cytokines, which are essential for host defense. In this review, we analyzed the effect of anti-inflammasome agents on the production of cytokines which are not regulated by inflammasome and involving in initial immune responses. As a result, the infiammasome inhibitors are put into three categories: non-effector, stimulator, or inhibitor of cytokine production. Even the stimulator of cytokine production ameliorated symptoms resulting from inflammasome activation in mouse models. Thus, we suggest ideal immune modulators targeting inflammasomes in order to enhance cytokine production while inhibiting cytokine maturation. | Huijeong Ahn Hyuk Moo Kwon Eunsong Lee Pyeung-Hyeun Kim Eui-Bae Jeung Geun-Shik Lee | 2018 | The Journal of Biomedical Research2018，32，6： | 5 |
| 15 | α-Glucosidase Inhibitory Activities of Lutein and Zeaxanthin Purified from Green Alga Chlorella ellipsoidea显示文摘α-Glucosidase inhibitors are used therapeutically to treat type-2 diabetes mellitus. Through a bioassay-guided fractionation technique, three carotenoids,(all-E)-lutein,(all-E)-zeaxanthin and(9-Z)-zeaxanthin, were purified from the green alga Chlorella ellipsoidea, in which(all-E)-lutein and(9-Z)-zeaxanthin had potent α-glucosidase inhibitory activity. IC_(50) values of(all-E)-lutein and(9-Z)-zeaxanthin were 70 and 53.5 μmol L^(-1) against Saccharomyces cerevisiae α-glucosidase, respectively, with non-competitive inhibition. In addition, IC_(50) values of(9-Z)-zeaxanthin against Bacillus stearothermophilus and rat-intestinal α-glucosidase were 805.1 and 671.2 μmol L^(-1), respectively. The K_i values of(all-E)-lutein and(9-Z)-zeaxanthin against S. cerevisiae α-glucosidase were 78.1 and 16.5 μmol L^(-1), respectively. Therefore, C. ellipsoidea carotenoids might be utilized as a novel candidate to prevent type-2 diabetes mellitus related disorders in food and medical industry. | QI Jia KIM Sang Moo | 2018 | Journal of Ocean University of China2018，17，4： | 4 |

| 17 | Inhibitory effects of rapamycin on the different stages of hepatic fibrosis显示文摘AIM:To investigate and compare the inhibitory effects of rapamycin in the different stages of liver fibrosis.METHODS:We performed bile duct ligation(BDL)in male Wistar rats(n=24).The experimental rats were classified into four groups:the BDL+/Rapa-group(untreated control,n=4),the BDL+/Rapa+group(treated14 d after BDL,n=8),the BDL+/Rapa++group(treated on the day after BDL,n=8),and the BDL-/Rapagroup(un-treated,sham-operated control,n=4).The BDL+/Rapa+and BDL+/Rapa++groups were administered rapamycin(2 mg/kg)for 28 d.The liver tissues were tested by immunohistochemical staining forα-smooth muscle actin(α-SMA)and cytokeratin.RESULTS:The liver mRNA levels of transforming growth factor(TGF)-β1 and platelet-derived growth factor(PDGF)were measured using the polymerase chain reaction.The protein levels of liver p70s6K and p-p70s6k were determined using Western blotting.α-SMA expression was lowest in the BDL+/Rapa++group.TGF-β1and PDGF expression levels in the rapamycin-treated group were lower than those in the un-treated group and higher than those in the control groups(TGF-β1:0.23±0.00 vs 0.34±0.01,0.23±0.0 vs 0.09±0.00,P<0.0001;PDGF:0.21±0.00 vs 0.34±0.01,0.21±0.0 vs 0.09±0.00,P<0.0001).The p70s6k and p-p70s6k levels decreased in the treated groups and were lowest in the BDL+/Rapa++group(p70s6k:1.05±0.17 vs 1.30±0.56,0.40±0.01 vs 1.30±0.56,P<0.0001;p-p70s6k:1.40±0.5 vs 1.67±0.12,0.70±0.01 vs 1.67±0.12,P<0.0001).CONCLUSION:The results of our study indicate that rapamycin has inhibitory effects on liver fibrosis,and the treatment is most effective in the early stages of fibrosis. | Yun Jeung Kim Eaum Seok Lee Seok Hyun Kim Heon Young Lee Seung Moo Noh Dae Young Kang Byung Seok Lee | 2014 | World Journal of Gastroenterology2014，20，23： | 3 |
| 18 | Risk factors for tuberculosis after gastrectomy in gastric cancer显示文摘AIM: To examine incidence of tuberculosis(TB) in gastrectomy patients and investigate the risk factors for developing TB after gastrectomy in patients with gastric cancer.METHODS: A retrospective cohort study of gastrectomy patients with gastric cancer was performed at a university-affiliated hospital in Seoul, South Korea between January 2007 and December 2009. We reviewed patient medical records and collected data associated with the risk of TB, surgery, and gastric cancer. Standardized incidence ratios(SIRs) of TB were calculated to compare the incidence of TB in gastrectomy patients with that in the general Korean population, and risk factors for TB after gastrectomies were analyzed.RESULTS: Among the 1776 gastrectomy patients, 0.9%(16/1776) developed post-gastrectomy TB, with an incidence of 223.7 cases per 100000 patients per year. The overall incidence of TB in gastrectomy patients, adjusted by sex and age, was significantly higher thanthat in the general population(SIR = 2.22, 95%CI: 1.27-3.60). Previous TB infection [odds ratio(OR) = 7.1, P < 0.001], lower body mass index(BMI)(kg/m2; OR = 1.21, P = 0.043) and gastrectomy extent(total gastrectomy vs subtotal gastrectomy)(OR = 3.48, P = 0.017) were significant risk factors for TB after gastrectomy in a multivariate analysis.CONCLUSION: TB incidence after gastrectomy is higher than that in the general population. Previous TB infection, lower BMI, and total gastrectomy are risk factors for TB after gastrectomy in patients with gastric cancer. | Won Jai Jung Young Mok Park Joo Han Song Kyung Soo Chung Song Yee Kim Eun Young Kim Ji Ye Jung Moo Suk Park Young Sam Kim Se Kyu Kim Joon Chang Sung Hoon Noh Ji Yeong An Young Ae Kang | 2016 | World Journal of Gastroenterology2016，22，8： | 3 |
| 19 | Bevacizumab as a second- or later-line of treatment for metastatic colorectal cancer显示文摘AIM: To determine the efficacy of bevacizumab in patients with metastatic colorectal cancer (MCRC) who have failed prior chemotherapy without bevacizumab. METHODS: Between March 2002 and June 2010, 40 patients in South Korea with MCRC who were treated with bevacizumab plus chemotherapy as a second or later-line treatment were analyzed retrospectively for their overall response rate (ORR), overall survival (OS), and progression-free survival (PFS). The tumor responses were assessed using the RECIST (Response Evaluation Criteria in Solid Tumors) guidelines. RESULTS: All of the patients had progressed under prior chemotherapy without bevacizumab. Three patients (7.5%) exhibited an ORR, twenty one patients (52.5%) exhibited stable disease (SD), and fifteen patients (37.5%) exhibited disease progression. The median duration of the OS and PFS were 14.0 and 6.13 mo respectively. The median OSs were 16.60, 14.07 and 13.00 mo for second-line, third-line and fourth- or later-line treatments, respectively. The median PFSs were 7.23, 7.30 and 3.87 mo for the second-line, third-line and fourth- or later-line treatments, respectively. CONCLUSION: In patients with MCRC, bevacizumab combined chemotherapy may be beneficial during second- or later-line treatment. | Lee Chun Park Ho Sup Lee Seong Hoon Shin Seun Ja Park Moo In Park Sung Yong Oh Hyuk Chan Kwon Jin ho Baek Young Jin Choi Myoung Joo Kang Yang Soo Kim | 2012 | World Journal of Gastroenterology2012，18，10： | 3 |
