| 1 | Carcinoma of the stomach: A review of epidemiology, pathogenesis, molecular genetics and chemoprevention显示文摘Carcinoma of the stomach is still the second most common cause of cancer death worldwide, although the incidence and mortality have fallen dramatically over the last 50 years in many regions. The incidence of gastric cancer varies in different parts of the world and among various ethnic groups. Despite advances in diagnosis and treatment, the 5-year survival rate of stomach cancer is only 20 per cent. Stomach cancer can be classified into intestinal and diffuse types based on epidemiological and clinicopathological features. The etiology of gastric cancer is multifactorial and includes both dietary and nondietary factors. The major diet-related risk factors implicated in stomach cancer development include high content of nitrates and high salt intake. Accumulating evidence has implicated the role of Helicobacter pylori (H. pylori) infection in the pathogenesis of gastric cancer. The development of gastric cancer is a complex, multistep process involving multiple genetic and epigenetic alterations of oncogenes, tumor suppressor genes, DNA repair genes, cell cycle regulators, and signaling molecules. A plausible program for gastric cancer prevention involves intake of a balanced diet containing fruits and vegetables, improved sanitationand hygiene, screening and treatment of H. pylori infection, and follow-up of precancerous lesions. The fact that diet plays an important role in the etiology of gastric cancer offers scope for nutritional chemoprevention. Animal models have been extensively used to analyze the stepwise evolution of gastric carcinogenesis and to test dietary chemopreventive agents. Development of multitargeted preventive and therapeutic strategies for gastric cancer is a major challenge for the future. | Siddavaram Nagini | 2012 | World Journal of Gastrointestinal Oncology2012，4，7： | 87 |
| 2 | Epidemiology of pancreatic cancer显示文摘Cancer of the pancreas remains one of the deadliest cancer types. Based on the GLOBOCAN 2012 estimates, pancreatic cancer causes more than 331000 deaths per year, ranking as the seventh leading cause of cancer death in both sexes together. Globally, about 338000 people had pancreatic cancer in 2012, making it the 11^(th) most common cancer. The highest incidence and mortality rates of pancreatic cancer are found in developed countries. Trends for pancreatic cancer incidence and mortality varied considerably in the world. A known cause of pancreatic cancer is tobacco smoking. This risk factor is likely to explain some of the international variations and gender differences. The overall five-year survival rate is about 6%(ranges from 2% to 9%), but this vary very small between developed and developing countries. To date, the causes of pancreatic cancer are still insufficiently known, although certain risk factors have been identified, such as smoking, obesity, genetics, diabetes, diet, inactivity. There are no current screening recommendations for pancreatic cancer, so primary prevention is of utmost importance. A better understanding of the etiology and identifying the risk factors is essential for the primary prevention of this disease. | Milena Ilic Irena Ilic | 2016 | World Journal of Gastroenterology2016，22，44： | 95 |
| 3 | Helicobacter pylori infection and risk of gastric cancer in Changle County,Fujian Province,China显示文摘AIM To evaluate the effects of Helicobacterpylori infection and other environmental factorson the development of gastric cancer.METHODS A population-based case-controlstudy was conducted in Changle County,FujianProvince.The primary gastric cancer cases werehistologically confirmed or diagnosed by surgerybetween,January 1996 and March 1998.Healthycontrols were randomly selected and matched byage,sex,and neighborhood of residence.Atotal of 101 pairs were included in the study.Specially trained interviewers conducted face-to-face interviews with the subjects according toa standardized questionnaire.Helicobacterpylori infections were measured by serum IgGantibody to Helicobacter pylori.ConditionalLogistic Regression analysis was used.RESULTS The presence of IgG antibody toHelicobacter pylori was 63.7% in studysubjects,56.0% in patients with cardiac cancer,and 60.5% in patients with non-cardiac gastriccancer.The risk factors of gastric cancer inChangle County were identified such as loweducational level[OR=3.864;95% confidenceinterval(95% CI)1.604-9.311],lowconsumption of fresh vegetables(OR=4.925;95%Cl 1.356-17.885),high intake of fish sauce(OR=10.587;95% Cl 2.821-39.738),unscheduled meals(OR=4.254;95%Cl 1.445- 12.552),and Helicobacter pylori infection(OR=3.453;95%Cl 0.901-13.224).CONCLUSION Helicobacter pylori infectionmay be important in the etiology of gastriccancer,but major risk factors other thanHelicobacter pylori are responsible for the highgastric morbidity in Changle County. | Lin Cai Shun Zhang Yu Zuo Feng Zhang | 2000 | World Journal of Gastroenterology2000，6，3： | 74 |
| 4 | Risk factors for cervical lymph node metastasis in papillary thyroid microcarcinoma: a study of 1,587 patients显示文摘Objective: The purposes of this study were to identify risk factors for cervical lymph node metastasis and to examine the association between BRAF^(V600E) status and clinical features in papillary thyroid microcarcinoma(PTMC).Methods: A total of 1,587 patients with PTMC, treated in Tianjin Medical University Cancer Institute and Hospital from January2011 to March 2013, underwent retrospective analysis. We reviewed and analyzed factors including clinical results, pathology records, ultrasound results, and BRAF^(V600E) status.Results: Multivariate logistic regression analyses demonstrated that gender(male) [odds ratio(OR) = 1.845, P = 0.000], age(< 45 years)(OR = 1.606, P = 0.000), tumor size(> 6 mm)(OR = 2.137, P = 0.000), bilateralism(OR = 2.011, P = 0.000) and extrathyroidal extension(OR = 1.555, P = 0.001) served as independent predictors of central lymph node metastasis(CLNM).Moreover, CLNM(OR = 29.354, P = 0.000) served as an independent predictor of lateral lymph node metastasis(LLNM). Among patients with a solitary primary tumor, those with tumor location in the lower third of the thyroid lobe or the isthmus were more likely to experience CLNM(P < 0.05). Univariate analyses indicated that CLNM, LLNM, extrathyroidal extension, and multifocality were not significantly associated with BRAF^(V600E) mutation.Conclusions: The present study suggested that prophylactic neck dissection of the central compartment should be considered in patients with PTMC, particularly in men with tumor size greater than 6 mm, age less than 45 years, extrathyroidal extension, and tumor bilaterality. Among patients with PTMC, BRAF^(V600E) mutation is not significantly associated with prognostic factors. For a better understanding of surgical management of PTMC and the risk factors, we recommend multicenter research and long-term follow-up. | Xiangqian Zheng Chen Peng Ming Gao Jingtai Zhi Xiukun Hou Jingzhu Zhao Xi Wei Jiadong Chi Dapeng Li Biyun Qian | 2019 | Cancer Biology & Medicine2019，16，1： | 54 |
| 5 | Gallstone recurrence after successful percutaneous cholecystolithotomy:a 10-year follow-up of 439 cases显示文摘BACKGROUND: Stone recurrence is a major problem in the medication of gallstones with gallbladder preservation. The aim of this study was to determine the long-term recurrence rate of gallstones and the clinical outcome after successful percutaneous cholecystolithotomy (PCCL) treatment, and to investigate the possible risk factors for gallstone recurrence. METHODS: After successful PCCL for gallstones, 439 patients were followed up during a 10-year period. The long-term gallstone recurrence rate and clinical outcome were evaluated. Risk factors associated with stone recurrence were identified. RESULTS: Gallstone recurrence was detected in 182 of 439 PCCL patients, giving an overall recurrence rate of 41.46%. The cumulative gallstone recurrence rate for each of the 10 post-operative years was 9.57%, 18.91%, 27.33%, 34.14%, 37.59%, 39.86%, 41.90%, 42.73%, 42.85%, and 43.21%, respectively. Among these recurrent patients, 94 were asymptomatic, 80 suffered from nonspecific upper gastrointestinal symptoms and 8 suffered from abdominal pain or biliary colic. Thirty-eight of the 182 patients were retreated with cholecystectomy. The risk factors for stone recurrence included a family history of gallstones, preference for fatty food, accompanying liver disease, multiple stones and poor gallbladder function pre-PCCL. CONCLUSIONS: In this study, the overall recurrence rate of gallstone was 41.46% during a 10-year period. The highest frequency of gallstone recurrence was during the 5th to 6th postoperative years and then continued to slowly increase. Risk factors for stone recurrence varied.We suggest that the use of PCCL in patients with gallstones should be considered carefully because of stone recurrence. | Zou, Yi-Ping Du, Ji-Dong Li, Wei-Min Xiao, Yin-Qi Xu, Hong-Bin Zheng, Fang Huang, Hui Liu, Hao-Run Li, Hu-Cheng | 2007 | Hepatobiliary & Pancreatic Diseases International2007，6，2： | 43 |
| 6 | Prevalence of and risk factors for non-alcoholic fatty liver disease in a Chinese population: An 8-year follow-up study显示文摘AIM: To investigate the prevalence of and risk factors for non-alcoholic fatty liver disease(NAFLD) in a Chinese population.METHODS: A total of 1948 adults from China was followed for 8 years. A cross-sectional study was performed to investigate the prevalence of NAFLD at baseline, and then the participants were followed for 8 years to investigate risk factors for the development of NAFLD.RESULTS: A total of 1948 participants were enrolled at baseline, of whom 691 were diagnosed with NAFLD. During the 8-year follow-up, 337 baseline NAFLD-free participants developed NAFLD. They had a greaterincrease in body mass index(BMI), serum uric acid, fasting plasma glucose, very low-density lipoprotein cholesterol and a considerable decrease in high-density lipoprotein cholesterol. 123 participants who had NAFLD at baseline lost NAFLD during the 8-year follow-up period. They had a greater decrease in BMI, fasting plasma glucose, triglycerides, total cholesterol, low-density lipoprotein cholesterol, alanine aminotransferase, aspartate aminotransferase, and γ-glutamyl transpeptidase.CONCLUSION: NAFLD is prevalent in Chinese population with a rapidly increasing tendency. It can be reversed when patients lose their weight, control their hyperlipidemia and hyperglycemia, and reduce the liver enzyme levels. | Zhen-Ya Lu Zhou Shao Ya-Li Li Muhuyati Wulasihan Xin-Hua Chen | 2016 | World Journal of Gastroenterology2016，22，13： | 42 |
| 7 | Gastrointestinal radiation injury:Symptoms,risk factors and mechanisms显示文摘Ionising radiation therapy is a common treatment modality for different types of cancer and its use is expected to increase with advances in screening and early detection of cancer.Radiation injury to the gastrointestinal tract is important factor working against better utility of this important therapeutic modality.Cancer survivors can suffer a wide variety of acute and chronic symptoms following radiotherapy,which significantly reduces their quality of life as well as adding an extra burden to the cost of health care.The accurate diagnosis and treatment of intestinal radiation injury often represents a clinical challenge to practicing physicians in both gastroenterology and oncology.Despite the growing recognition of the problem and some advances in understanding the cellular and molecular mechanisms of radiation injury,relatively little is known about the pathophysiology of gastrointestinal radiation injury or any possible susceptibility factors that could aggravate its severity.The aims of this review are to examine the various clinical manifestations of post-radiation gastrointestinal symptoms,to discuss possible patient and treatment factors implicated in normal gastrointestinal tissue radiosensitivity and to outline different mechanisms of intestinal tissue injury. | Abobakr K Shadad Frank J Sullivan Joseph D Martin Laurence J Egan | 2013 | World Journal of Gastroenterology2013，19，2： | 35 |
| 8 | Prevalence of and risk factors for gallstones in Uighur and Han Chinese显示文摘AIM:To perform a single-centre survey of the prevalence of and possible risk factors for gallstones in Uighur and Han Chinese.METHODS:Complete medical data for 9455 patients were collected from the medical centre of our hospital,and the overall prevalence of gallstones as well as the prevalence in different ethnic groups was studied.The risk factors for gallstones in different ethnic groups were identified in a univariate analysis,and variables with statistical significance were analysed by unconditional multiple logistic regression,to primarily explore the similarities and differences in gallstone risk factors between different ethnic groups.RESULTS:The prevalence of gallstones was significantly higher in the Uighur population than in the Hanpopulation(22.87%vs 11.64%,P<0.05).Further analysis of risk factors for gallstones based on the different ethnic areas revealed that age was a risk factor for gallstones in both groups;triglycerides,body-mass index(BMI)and high-density lipoprotein were risk factors for gallstones in the Han population,while total cholesterol(TC),gender and fatty liver were risk factors in the Uighur population.The Uighur patients were older than the Han patients,and had higher BMI,TC,low-density lipoprotein,female rate and fatty liver rate,while the incidence of hypertension was lower than that in the Han patients.CONCLUSION:The prevalence of and risk factors for gallstones differ between the Uighur and Han populations. | Li Zhu Aikebaier Aili Cheng Zhang Aili Saiding Kelimu Abudureyimu Xinjiang Medical University | 2014 | World Journal of Gastroenterology2014，20，40： | 39 |
| 9 | Prediction of risk factors for lymph node metastasis in early gastric cancer显示文摘AIM:To explore risk factors for lymph node metastases in early gastric cancer(EGC) and to confirm the appropriate range of lymph node dissection.METHODS:A total of 202 patients with EGC who underwent curative gastrectomy with lymphadenectomy in the Department of Surgery,Xinhua Hospital and Ruijin Hospital of Shanghai Jiaotong University Medical School between November 2003 and July 2009,were retrospectively reviewed.Both the surgical procedure and the extent of lymph node dissection were based on the recommendations of the Japanese gastric cancer treatment guidelines.The macroscopic type was classified as elevated(type Ⅰ or Ⅱa),flat(Ⅱb),or depressed(Ⅱc or Ⅲ).Histopathologically,papillary and tubular adenocarcinomas were grouped together as differentiated adenocarcinomas,and poorly differentiated and signet-ring cell adenocarcinomas were regarded as undifferentiated adenocarcinomas.Univariate and multivariate analyses of lymph node metastases and patient and tumor characteristics were undertaken.RESULTS:The lymph node metastases rate in patients with EGC was 14.4%.Among these,the rate for mucosal cancer was 5.4%,and 8.9% for submucosal cancer.Univariate analysis showed an obvious correlation between lymph node metastases and tumor location,depth of invasion,morphological classification and venous invasion(χ 2 = 122.901,P = 0.001;χ 2 = 7.14,P = 0.008;χ 2 = 79.523,P = 0.001;χ 2 = 8.687,P = 0.003,respectively).In patients with submucosal cancers,the lymph node metastases rate in patients with venous invasion(60%,3/5) was higher than in those without invasion(20%,15/75)(χ 2 = 4.301,P = 0.038).Multivariate logistic regression analysis revealed that the depth of invasion was the only independent risk factor for lymph node metastases in EGC [P = 0.018,Exp(B) = 2.744].Among the patients with lymph node metastases,29 cases(14.4%) were at N1,seven cases were at N2(3.5%),and two cases were at N3(1.0%).Univariate analysis of variance revealed a close relationship between the depth of invasion and lymph node metastases at pN 1(P = 0.008).CONCLUSION:The depth of invasion was the only independent risk factor for lymph node metastases.Risk factors for metastases should be considered when choosing surgery for EGC. | Gang Ren Rong Cai Wen-Jie Zhang Jin-Ming Ou Ye-Ning Jin Wen-Hua Li | 2013 | World Journal of Gastroenterology2013，19，20： | 31 |
| 10 | Cardiovascular risk factors for acute stroke: Risk profiles in the different subtypes of ischemic stroke显示文摘Timely diagnosis and control of cardiovascular risk factors is a priority objective for adequate primary and secondary prevention of acute stroke. Hypertension, atrial fibrillation and diabetes mellitus are the most common risk factors for acute cerebrovascular events, although novel risk factors, such as sleep-disordered breathing, inflammatory markers or carotid intima-media thickness have been identified. However, the cardiovascular risk factors profile differs according to the different subtypes of ischemic stroke. Atrial fibrillation and ischemic heart disease are more frequent in patients with cardioembolic infarction, hypertension and diabetes in patients with lacunar stroke, and vascular peripheral disease, hypertension, diabetes, previous transient ischemic attack and chronic obstructive pulmonary disease in patients with atherothrombotic infarction. This review aims to present updated data on risk factors for acute ischemic stroke as well as to describe the usefulness of new and emerging vascular risk factors in stroke patients. | Adrià Arboix | 2015 | World Journal of Clinical Cases2015，3，5： | 29 |
| 11 | Follow-up of intestinal metaplasia in the stomach: When, how and why显示文摘Gastric cancer remains the second most frequent cause of cancer-related mortality in the world. Screening programs in some Asian countries are impractical in the majority of other countries worldwide. Therefore, follow-up of precancerous lesions is advisable for secondary gastric cancer prevention. Intestinal metaplasia (IM) is recognized as a precancerous lesion for gastric cancer, increasing the risk by 6-fold. IM is highly prevalent in the general population, being detected in nearly 1 of every 4 patients undergoing upper endoscopy. The IM prevalence rate is significantly higher in patients with Helicobacter pylori (H. pylori) infection, in first-degree relatives of gastric cancer patients, in smokers and it increases with patient age. IM is the 'breaking point' in the gastric carcinogenesis cascade and does not appear to regress following H. pylori eradication, although the cure of infection may slow its progression. Gastric cancer risk is higher in patients with incomplete-type IM, in those with both antral and gastric body involvement, and the risk significantly increases with IM extension over 20% of the gastric mucosa. Scheduled endoscopic control could be cost-effective in IM patients, depending on the yearly incidence of gastric cancer in IM patients, the stage of gastric cancer at diagnosis discovered at surveillance, and the cost of endoscopy. As a pragmatic behavior, yearly endoscopic control would appear justified in all IM patients with at least one of these conditions: (1) IM extension > 20%; (2) the presence of incomplete type IM; (3) first-degree relative of gastric cancer patients; and (4) smokers. In the remaining IM patients, a less intensive (2-3 years) could be proposed. | Angelo Zullo Cesare Hassan Adriana Romiti Michela Giusto Carmine Guerriero Roberto Lorenzetti Salvatore MA Campo Silverio Tomao | 2012 | World Journal of Gastrointestinal Oncology2012，4，3： | 25 |
| 12 | Complications of radiofrequency ablation of hepatic tumors:Frequency and risk factors显示文摘Radiofrequency ablation(RFA)has become an important option in the therapy of primary and secondary hepatic tumors.Surgical resection is still the best treatment option,but only a few of these patients are candidates for surgery:multilobar disease,insufficient liver reserve that will lead to liver failure after resection,extra-hepatic disease,proximity to major bile ducts and vessels,and co-morbidities.RFA has a low mortality and morbidity rate and is considered to be safe.Thus,complications occur and vary widely in the literature.Complications are caused by thermal damage,direct needle injury,infection and the patient’s co-morbidities.Tumor type,type of approach,number of lesions,tumor localization,underlying hepatic disease,the physician’s experience,associated hepatic resection and lesion size have been described as factors significantly associated with complications.The physician in charge should promptly recognize high-risk patients more susceptible to complications,perform a close post procedure follow-up and manage them early and adequately if they occur.We aim to describe complications from RFA of hepatic tumors and their risk factors,as well as a few techniques to avoid them.This way,others can decrease their morbidity rates with better outcomes. | Alexandre Zanchenko Fonseca Stephanie Santin Luiz Guilherme Lisboa Gomes Jaques Waisberg Marcelo Augusto Fontenelle Ribeiro Jr. | 2014 | World Journal of Hepatology2014，6，3： | 24 |
| 13 | Risk factors for early recurrence of small hepatocellular carcinoma after curative resection显示文摘BACKGROUND:Poorer prognosis is seen in patients with hepatocellular carcinoma (HCC) after curative hepatic resection with early recurrence (≤1 year) than in those with late recurrence (>1 year).This study aimed to identify risk factors for postoperative early recurrence of small HCC (≤3 cm in diameter).METHODS:The study population consisted of 158 patients who underwent curative resection for small HCC between January 2002 and July 2004.Risk factors for early recurrence were analyzed.RESULTS:Thirty-three (20.8%) patients developed early recurrence after surgery.Univariate analysis showed the following significant risk factors for early recurrence in small HCC:serum alpha-fetoprotein (AFP) level >100 ng/ml,lack of tumor capsule formation,microscopic vascular invasion,high Edmonson-Steiner grades,and cytokeratin-19 (CK-19) expression (P<0.05).Multivariate stepwise logistic regression analysis showed that serum AFP level >100 ng/ml (odds ratio 2.561,95% confidence interval 1.057 to 6.206,P=0.037) and microscopic vascular invasion (odds ratio 4.549,95% confidence interval 1.865 to 11.097,P=0.001) were independent factors.CONCLUSIONS:Postoperative early recurrence is related to serum AFP level >100 ng/ml and microscopic vascular invasion in patients with small HCC.Adjuvant therapy and careful follow-up are required for patients with these risk factors. | Zhou, Yan-Ming Yang, Jia-Mei Li, Bin Yin, Zheng-Feng Xu, Feng Wang, Bin Xu, Wen Kan, Tong | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，1： | 24 |
| 14 | Multicenter case-control study of the risk factors for ulcerative colitis in China显示文摘AIM:To evaluate potential risk factors in the development of ulcerative colitis(UC) in China.METHODS:A total of 1308 patients with UC and 1308 age-matched and sex-matched controls were prospectively studied in China.The UC cases were collected from 17 hospitals in China from April 2007 to April 2010.Uniform questionnaires were designed to investigate risk factors including smoking,appendectomy,stress,socio-economic conditions,nonsteroidal antiinflammatory drugs(NSAIDs),oral contraceptives,diet,breastfeeding,infections and family sanitary conditions.Group comparisons by each factor were done using simple logistic regression analysis.Conditional logistic regression was used for multivariate analysis.RESULTS:By univariate analysis,the variables predictive of UC included feeling stress,light and heavy alcoholic drinking,spicy food,sugar consumption and infectious diarrhea,while heavy tea intake and tap water consumption were protective against UC.On multivariate analysis,the protective factor for UC was tap water consumption [odds ratios(OR) = 0.424,95%CI:0.302-0.594,P < 0.001];while the potential risk factors for UC were heavy sugar consumption(OR = 1.632,95%CI:1.156-2.305,P < 0.001),spicy food(light intake:OR = 3.329,95%CI:2.282-4.857,P < 0.001;heavy intake:OR = 3.979,95%CI:2.700-5.863,P < 0.001),and often feeling stress(OR = 1.981,95%CI:1.447-2.711,P < 0.001).Other factors,such as smoking habit,appendectomy,breastfeeding,a history of measles,rural or urban residence,education,oral contraceptives,and NSAID use have not been found to have a significant association with the development of UC in the present study.CONCLUSION:Our study showed tap water consumption was a protective factor for UC,while spicy food,heavy sugar consumption and often feeling stress were risk factors for UC in this Chinese population. | Yu-Fang Wang Qin Ou-yang Bing Xia Li-Na Liu Fang Gu Kai-Fang Zhou Qiao Mei Rui-Hua Shi Zhi-Hua Ran Xiao-Di Wang Pin-Jin Hu Kai-Chun Wu Xin-Guang Liu Ying-Lei Miao Ying Han Xiao-Ping Wu Guo-Bing He Jie Zhong Guan-Jian Liu | 2013 | World Journal of Gastroenterology2013，19，11： | 24 |
| 15 | Prevalence and risk factors of fatty liver disease in Chengdu,Southwest China显示文摘BACKGROUND:Fatty liver disease(FLD)is increasingly recognized as one of the most common chronic liver diseases in China.This study aimed to investigate the prevalence and risk factors of FLD in Chengdu,Southwest China,and to provide a relevant basis for the prevention and intervention of FLD. METHODS:Altogether 9094 subjects(4721 men and 4373 women)of over 18 years old who had received a medical checkup in the West China Hospital of Sichuan University between January and December 2007 were evaluated for FLD.FLD was diagnosed by ultrasonography.Body mass index(BMI),height,body weight,blood pressure,fasting plasma glucose(FPG),triglycerides(TG),total cholesterol (TCh),alanine aminotransferase(ALT),hepatitis B surface antigen(HBsAg),high-density lipoprotein cholesterol (HDL-C),and low-density lipoprotein cholesterol(LDL-C) were measured using routine laboratory methods. RESULTS:The overall prevalence of FLD was 12.5%,which was more than 3-fold higher in males than in females (18.9%vs.5.7%,χ2=359.624,P<0.001).The prevalence increased with age in females and males of less than 50 years.The prevalence of alcoholic,suspected alcoholic,and non-alcoholic FLD was 2.6%,3.6%,and 6.3%,respectively. Multiple logistic regression analyses showed that 10 factors (male sex,age,BMI,FPG,hypertension,TG,TCh,HDL-C, LDL-C,and ALT abnormalities)were closely related to FLD. In heavy drinkers,obesity increased the risk of FLD by 23.78-fold(95%CI,10.22-55.33),but heavy drinking was only associated with a 2-fold(95%CI,1.50-2.66)increased risk in obese subjects.CONCLUSIONS:The prevalence of FLD among a health- checkup population in Chengdu,Southwest China was lower than the published for other areas of China.FLD in Chengdu adults was found to be closely associated with sex, age,BMI,and other metabolic syndrome features. | Li, Hong Wang, You-Juan Tan, Ke Zeng, Li Liu, Li Liu, Feng-Jun Zhou, Tao-You Chen, En-Qiang Tang, Hong | 2009 | Hepatobiliary & Pancreatic Diseases International2009，8，4： | 22 |
| 16 | Prevalence and risk factors of gallbladder polypoid lesions in Chinese petrochemical employees显示文摘AIM:To investigate the prevalence and risk factors of polypoid lesions of the gallbladder (PLGs) in petrochemical employees in Ningbo, Zhejiang Province, China. METHODS:All active and retired employees aged 20-90 years (n = 11098) of a refinery and chemical plant in eastern China were requested to participate in a health survey. The participants were subjected to interview, physical examination, laboratory assessments and ultrasonography. All the participants were invitedto have a physical examination after a face-to-face interview. Fasting blood samples were obtained from the antecubital vein, and the samples were used for the analysis of biochemical values. Abdominal ultrasonography was conducted. RESULTS:A total of 10461 (7331 men and 3130 women) current and former petrochemical employees attended for screening. The overall prevalence of postcholecystectomy, gallstones and PLGs was 0.9%, 5.2% and 7.4%, respectively. Compared with the increased prevalence of either gallstones or post-cholecystectomy in older persons, PLGs were more common in the middle-aged, peaking in those aged 40-59 years. Excluding the patients with gallstones, gallstones mixed with PLGs, or those who had undergone cholecystectomy, in the remaining 9828 participants, the prevalence of PLGs in men (8.9%) was significantly higher than that in women (5.5%, P < 0.001). The analyzed risk factors with increased OR for the development of PLGs were male gender (OR = 1.799, P < 0.001), age ≥ 30 years (OR = 2.699, P < 0.001) and hepatitis B surface antigen (HBsAg) positivity (OR = 1.374, P = 0.006). CONCLUSION:PLGs are not rare among Chinese petrochemical employees. Male gender, HBsAg positivity, and middle age are risk factors for developing PLGs. | Yu-Shan Mao Yi-Feng Mai Fu-Jun Li Yan-Ming Zhang Ke-Min Hu Zhong-Li Hong Zhong-Wei Zhu | 2013 | World Journal of Gastroenterology2013，19，27： | 23 |

| 18 | Risk factors of intrahepatic cholangiocarcinoma in patients with hepatolithiasis:a case-control study显示文摘BACKGROUND:Why 3.3% to 10% of all patients with hepatolithiasis develop intrahepatic cholangiocarcinoma (ICC) remains unknown.We carried out a hospital-based case-control study to identify risk factors for the development of ICC in patients with hepatolithiasis in China.METHODS:Eighty-seven patients with pathologically diagnosed hepatolithiasis associated with ICC and 228 with hepatolithiasis alone matched by sex,age (±2 years),hospital admittance and place of residence were interviewed during the period of 2000-2008.Odds ratios (OR) and 95% confidence intervals (CI) were calculated for each risk factor.RESULTS:Among the patients with hepatolithiasis associated with ICC,the mean age was 57.7 years and 61.0% were female Univariate analysis showed that the significant risk factors for ICC development in hepatolithiasis were smoking,family history of cancer,appendectomy during childhood (under age 20),and duration of symptoms >10 years.In multivariate stepwise logistic regression analysis,smoking (OR=1.931,95% CI:1.000-3.731),family history of cancer (OR=5.175,95% CI:1.216-22.022),and duration of symptoms >10 years (OR=2.348 95% CI:1.394-3.952) were independent factors.CONCLUSION:Smoking,family history of cancer and duration of symptoms >10 years may be risk factors for ICC in patients with hepatolithiasis. | Zhen-Yu Liu,Yan-Ming Zhou,Le-Hua Shi and Zheng-Feng YinAuthor Affiliations:Molecular Oncology Laboratory and Department of Comprehensive Treatment I,Eastern Hepatobiliary Surgery Hospital,Second Military Medical University,Shanghai 200438,China Department of Hepato-Biliary-Pancreato-Vascular Surgery,First Affiliated Hospital,Xiamen University,Xiamen 361003,China | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，6： | 21 |
| 19 | Risk factors associated with early and late recurrence after curative resection of hepatocellular carcinoma: a single institution's experience with 398 consecutive patients显示文摘BACKGROUND: Surgical resection is an important curative treatment for hepatocellular carcinoma (HCC); however, some patients experience an unexpected recurrence even after hepatectomy. The present study aimed to investigate risk factors and predictive criteria for early and late recurrence of HCC after resection.METHODS: A retrospective analysis of 398 Chinese patients who received curative resection for HCC was conducted. Patients were divided into three groups: without recurrence, early recurrence and late recurrence. Prognostic factors and predictive criteria for early and late recurrence were statistically analyzed. RESULTS: The cumulative recurrence-free survival rates at1, 2, 3, 4, and 5 years were 75.5%, 58.2%, 54.1%, 40.5%, and28.7%, respectively. The distribution of the time to recurrence suggested that recurrence could be divided into early phase(before 2 years; n=164) and late phase (after 2 years; n=83)Cox's multivariate proportional hazard model analysis revealed that multiplicity of tumors (P=0.004) and venous infiltration(P=0.002) were independent risk factors associated with early recurrence. In contrast, indocyanine green retention rate at 15minutes (P=0.007), serum albumin level (P=0.045), and HBeAg status ( =0.028) proved to be significant independent adverse prognostic factors for late recurrence. Patients with at least 1of the 2 early recurrence risk factors (multiplicity of tumors ≥2and venous infiltration) or with 2 or more late recurrence risk factors are often susceptible to recurrence (P=1.36e-4 and 1.0e-6respectively).CONCLUSIONS: Early and late recurrences correlate with different risk factors and predictive criteria. Early recurrence primarily results from intrahepatic metastases, while late recurrence may be multicentric in origin. | Zheng-Gui Du Yong-Gang Wei Ke-Fei Chen Bo Li | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，2： | 20 |
| 20 | Portosplenomesenteric vein thrombosis in patients with early-stage severe acute pancreatitis显示文摘AIM To investigate the incidence and risk factors of portosplenomesenteric vein thrombosis(PSMVT) in the early stage of severe acute pancreatitis(SAP).METHODS Patients with SAP in a tertiary care setting from January 2014 to December 2016 were retrospectively reviewed. All contrast-enhanced computed tomography(CT) studies were reassessed and reviewed. Clinical outcome measures were compared between SAP patients with and without PSMVT in the early stage of the disease. Univariate and multivariate logistic regression analyses were sequentially performed to assess potential risk factors for the development of PSMVT in SAP patients. A receiver operating characteristic(ROC) curve was generated for the qualifying independent risk factors.RESULTS Twenty-five of the one hundred and forty(17.86%) SAP patients developed PSMVT 6.19 ± 2.43 d after acute pancreatitis(AP) onset. PSMVT was confirmed by contrast-enhanced CT. Multivariate stepwise logistic regression analyses showed that Balthazar's CT severity index(CTSI) scores [odds ratio(OR): 2.742; 95% confidence interval(CI): 1.664-4.519; P = 0.000], hypoalbuminemia(serum albumin level < 25 g/L)(OR: 32.573; 95%CI: 2.711-391.353; P = 0.006) and gastrointestinal wall thickening(OR: 4.367, 95%CI: 1.218-15.658; P = 0.024) were independent risk factors for PSMVT developed in patients with SAP. The area under the ROC curve for Balthazar's CTSI scores was 0.777(P = 0.000), the sensitivity was 52%, and the specificity was 93% at a cut-off value of 5.5.CONCLUSION High Balthazar's CTSI scores, hypoalbuminemia and gastrointestinal wall thickening are independent risk factors for PSMVT developed in the early stage of SAP. | Ling Ding Feng Deng Chen Yu Wen-Hua He Liang Xia Mi Zhou Xin Huang Yu-Peng Lei Xiao-Jiang Zhou Yin Zhu Nong-Hua Lu | 2018 | World Journal of Gastroenterology2018，24，35： | 20 |
