| 1 | Serum leptin levels and insulin resistance are associated with gallstone disease in overweight subjects显示文摘AIM: To establish an association between the serum leptin levels and the development of gallstone disease (GD).METHODS: We carried out a non-matched case-controlled study in a university hospital in Mexico City. Two hundred and eighty-seven subjects were included: 97 cases with gallstones and 190 controls. Body mass index (BMI), fasting plasma leptin, insulin, serum lipid, and lipoprotein levels were measured. Insulin resistance was calculated by homeostasis model assessment (HOMA-IR). Unconditional logistic regression analysis (univariate and multivariate)stratified by BMI was used to calculate the risk of GD.RESULTS: The multivariate conditional regression analysis revealed a model for those patients with BMI <30. The selected variables in the model were HOMA-IR index with OR = 1.31, P= 0.02 and leptin higher than median with OR = 2.11, P= 0.05. In the stratum of BMI ≥30, we did not find a useful model.CONCLUSION: We concluded that insulin resistance and the development of GD appears to be associated with serum leptin levels in subjects with overweight, but not in obese subjects with similar metabolic profiles. | Nahum Méndez-Sánchez Luisa B Bermejo-Martínez Yolanda Vi(n|~)als Norberto C Chavez-Tapia Irina Vander Graff Guadalupe Ponciano-Rodríguez Martha H Ramos Misael Uribe | 2005 | World Journal of Gastroenterology2005，11，39： | 11 |
| 2 | Lymphomatous involvement of gastrointestinal tract: Evaluation by positron emission tomography with ^(18)F-fluorodeoxyglucose显示文摘AIM: To demonstrate the 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) findings in patients with non-Hodgkin's lymphoma (NHL) involving the gastrointestinal (GI) tract and the clinical utility of modality despite of the known normal uptake of FDG in the GI tract.METHODS: Thirty-three patients with biopsy-proven gastrointestinal NHL who had undergone FDG-PET scan were included. All the patients were injected with 10-15 mCi FDG and scanned approximately 60 min later with a CTI/Siemens HR (+) PET scanner. PET scans were reviewed and the maximum standard uptake value (SUVmax) of the lesions was measured before and after the treatment,if data were available and compared with histologic diagnoses.RESULTS: Twenty-five patients had a high-grade lymphoma and eight had a low-grade lymphoma. The stomach was the most common site of the involvement (20 patients). In high-grade lymphoma, PET showed focal nodular or diffuse hypermetabolic activity. The average SUVmax±SD was 11.58±5.83. After the therapy,the patients whose biopsies showed no evidence of lymphoma had a lower uptake without focal lesions.The SUVmax±SD decreased from 11.58±5.83 to 2.21±0.78. In patients whose post-treatment biopsies showed lymphoma, the SUVmax±SD was 9.42±6.27. Low-grade follicular lymphomas of the colon and stomach showed diffuse hypermetabolic activity in the bowel wall (SUVmax 8.2 and 10.3, respectively). The SUVmax was 2.02-3.8 (mean 3.02) in the stomach lesions of patients with MALT lymphoma.CONCLUSION: 18F-FDG PET contributes to the diagnosis of high-grade gastrointestinal non-Hodgkin's lymphoma,even when there is the normal background FDG activity. Furthermore, the SUV plays a role in evaluating treatment response. Low-grade NHL demonstrates FDG uptake but at a lesser intensity than seen in high-grade NHL. | Sith Phongkitkarun Vithya Varavithya Toshiki Kazama Silvana C Faria Martha V Mar Donald A Podoloff Homer A Macapinlac | 2005 | World Journal of Gastroenterology2005，11，46： | 6 |
| 3 | Smoking is not associated with nonalcoholic fatty liver disease显示文摘瞄准:分析在吸烟和不含酒精的脂肝疾病(NAFLD ) 之间的关系。方法:这是一张健康人口的代表性的研究,在墨西哥在一所大学医院的一个检查单位执行了城市。我们注册了 933 个题目, 368 个当前的吸烟者(盒子) 和从来没吸过的 565 个人(控制) 。人口统计、新陈代谢、生物化学的变量在二个组被测量。NAFLD 被超声和新陈代谢的症候群根据 ATPIII 决定。结果:548 个男人(205 个盒子和 343 控制) 和 337 个女人(114 个盒子和 223 控制) 的一个总数在分析被包括。盒子和控制之间的统计差别仅仅在高血压流行被观察(6.6% 对 11.3% , P <
0.05;盒子和控制分别地),高密度的脂蛋白( 1.00 +/- 0.26 对 1.06 +/- 0.28 mmol/L , P <
0.005 ), triglycerides ( 2.18 +/- 1.49 对 1.84 +/- 1.1 mmol/L , P <
0.001 ),并且红细胞沉降率( 11.3 +/- 9.3 对 13.5 +/- 11.9 mm/h , P <
0.001 )。没有差别在 NAFLD 的流行被观察(22.27% 对 29.68% , P = NS ) 并且新陈代谢的症候群(41.69% 对 36.74% , P = NS ) 。Univariate 分析证明吸烟不是为 NAFLD 的一个风险因素(或 = 0.89, 95% CI 0.65-1.21 ) 。结论:在 NAFLD 流行的差别都没在当前的吸烟者和不抽烟的人之间被观察,并且而且,没有差别在重吸烟者(超过 20 包装 / 年) 被观察,显示在吸烟和 NAFLD 之间没有关系。 | Norberto C Chavez-Tapia Javier Lizardi-Cervera Oliver Perez-Bautista Martha H Ramos-Ostos Misael Uribe | 2006 | World Journal of Gastroenterology2006，12，32： | 2 |
