AIM: To determine whether Helicobacter pylori (H. pylori)infected children have reduced body weight (BW) and height (BH) growth, and if H. pylori eradication may restore growth while improving serum acylated ghrelin. METHODS: This longitudinal cohort study with oneyear follow-up enrolled 1222 children aged 4 to 12 years old into an observation cohort (18 with and 318 without H. pylori ) and intervention cohort (75 with and 811 without). The 7-d triple therapy was used for eradication in the intervention cohort. The net increases of BW and BH as well serum acylated ghrelin after oneyear follow-up were compared between successful eradicated H. pylori-infected children and controls. RESULTS: In the observation cohort, the H. pylori - infected children had lower z score of BW (-1.11 ± 0.47 vs 0.35 ± 0.69, P = 0.01) and body mass index (BMI) (0.06 ± 0.45 vs 0.44 ± 0.73, P = 0.02) at enrollment and lower net BW gain after one-year follow-up (3.3 ± 2.1 kg vs 4.5 ± 2.4 kg, P = 0.04) than the non-infected controls. In the intervention cohort, the H. pylori - infected children had lower z score of BMI (0.25 ± 1.09 vs 0.68 ± 0.87, P = 0.009) and serum acylated ghrelin levels (41.8 ± 35.6 pg/mL vs 83.6 ± 24.2 pg/mL, P < 0.001) than the non-infected controls. In addition to restoring decreased serum ghrelin levels (87.7 ± 38.0 pg/mL vs 44.2 ± 39.0 pg/mL, P < 0.001), the H. pylori - infected children with successful eradication had higher net gains (P < 0.05) and increase of z scores (P < 0.05) of both BW and BH as compared with non-infected controls after one-year follow-up. CONCLUSION:H. pylori-infected children are associated with low serum acylated ghrelin and growth retardation. Successful eradication of H. pylori restores ghrelin levels and increases growth in children.

Fluorescence imaging is a non-invasive and highly sensitive bioimaging technique that has shown remarkable strides in plant science. It enables real-time monitoring and analysis of biological and pathological processes in plants by labeling specific molecular or cellular structures with fluorescent probes. However, tissue scattering and phytochrome interference have been obstacles for conventional fluorescence imaging of plants in the ultraviolet and visible spectrum, resulting in unsatisfactory imaging quality. Fortunately, advances in near-infrared(NIR) fluorescence imaging technology(650-900 nm) offer superior spatial-temporal resolution and reduced tissue scattering, which is sure to improve plant imaging quality. In this review, we summarize recent progress in the development of NIR fluorescence imaging probes and their applications for in vivo plant imaging and the identification of plant-related biomolecules. We hope this review provides a new perspective for plant science research and highlights NIR fluorescence imaging as a powerful tool for analyzing plant physiology, adaptive mechanisms, and coping with environmental stress in the near future.

Is a split-dose regimen of 2 L polyethylene glycol plus ascorbic acid tolerable for colonoscopy in an early morning visit to a comprehensive medical check-up?

World Journal of Gastroenterology 2017年第6期23卷 1030-1037页

作者： Ji Yeon Seo Changhyun Lee Eun Hyo Jin Mi Hyun Yun Joo Hyun Lim Hae Yeon Kang jong in yang Su Jin Chung Sun Young yang Joo Sung Kim Department of Internal Medicine and Healthcare Research Institute Healthcare System Gangnam CenterSeoul National University Hospital Department of Nursing Healthcare System Gangnam CenterSeoul National University Hospital

To evaluate the effectiveness and tolerability of a split-dose 2 L polyethylene glycol (PEG)/ascorbic acid (AA) regimen for healthy examinees who visited for comprehensive medical check-up in the early *** February 2015 to March 2015, examinees of average risk who were scheduled for a colonoscopy in the morning were retrospectively *** 189 examinees were divided into split-dose and non-split-dose groups. The adequacy of bowel preparation for the split-dose group vs the non-split-dose group was 96.8% vs 85.2%, respectively, P < 0.001, and the compliance of the last meal restriction was 74.6% vs 58.2%, respectively, P < 0.001. The sleep disturbance (P < 0.001) was more prevalent in the split-dose group, however the willingness to repeat the same preparation method (P = 0.243) was not different in both groups. The split-dose regimen was the most important factor influencing adequate bowel preparation in multivariate analysis (HR = 10.89, 95%CI: 6.53-18.17, P < 0.001).CONCLUSIONA split-dose regimen of 2 L PEG/AA for an early morning colonoscopy was more effective and showed better compliance for diet restriction without any difference in satisfaction and discomfort. Introducing a split-dose regimen of 2 L PEG/AA to morning colonoscopy examinees is effective and tolerable in a comprehensive medical check-up setting.

Brain activation patterns associated with sexual orientation in homosexual male and female: a case study with 3.0T fMRI

引用

Journal of Biomedical Science and Engineering 2011年第3期4卷 196-199页

作者： Gwang-Won Kim Gwang-Woo Jeong jong-Chul yang 不详

This study was performed to clarify the sexual orien-tation in a 19-year-old homosexual male and a 20-year-old homosexual female by using a functional magnetic resonance imaging (fMRI) with viewing male and female erotic nude pictures. The sex hor-mone levels of the homosexual male and female were in the normal range of healthy heterosexual males and females, respectively. In both homosexuals more significant brain activities were observed while view-ing the nude pictures of the same genetic sex than those of the opposite sex in the frontal cortex, parietal cortex, occipital cortex, anterior cingulate gyrus, amygdala, midbrain, hippocampus, orbitofrontal cortex, parahippocampal gyrus, thalamus, globus pallidus, and putamen, which are known to be re-sponsive to sexual arousal. The homosexual male and female showed a tendency toward higher sexual arousal to the same genetic sex as comparison with the opposite sex. This finding may be useful to un-derstand the different neural mechanisms on sexual arousal in homosexuals.
