《医学前沿(英文)》 2010年 第4卷 第4期   页码 436-442 doi: 10.1007/s11684-010-0200-9

摘要: The recurrence of colorectal adenoma (CRA) is high. Although there are guidelines for colonoscopy surveillance after polypectomy in other countries, little is known about its recurrence rate and recurrence peak, especially in China. The aim of the present research is to investigate how long after polypectomy follow-up should take and to analyze risk factors of recurrence. 1208 patients who received polypectomies from five clinical research centers in four regions of China (Shanghai, Guangzhou, Nanjing and Beijing) were included. They were divided into 4 groups: group A (follow-up≤1 year after polypectomy), group B (follow-up 2–3 years after polypectomy), group C (follow-up 4–5 years after polypectomy), and group D (follow-up>5 years after polypectomy). The sex, age, adenoma location, size, number, and pathological characteristics were compared. On the whole, the recurrence rate was 59.46% in group A, 61.09% in group B, 78.07% in group C, and 87.12% in group D, which indicated an increased tendency with a prolonged follow-up duration. There was a significant difference between group A and C or D, and between group B and C or D (<0.01), but there was no statistical difference between group A and B. Additionally, the recurrent patients in the first year had a recurrence rate of 97.33% in the first three years (59.46/61.09), which means that the peak of recurrence was almost entirely concentrated in the first year. The recurrence rate was higher in males and the elder. The risk factors included multiple numbers, villous feature, high-grade dysplasia of medium or smaller size and location in the distal colon. In conclusion, the peak of recurrence was almost totally concentrated in the first year; meanwhile, the first year follow-up is of critical importance in China. It may not be necessary to do the follow-up examination during the second and third years, but after three years, another colonoscopy should be undertaken.

摘要: 2022 marks the 15th anniversary of the journal of Frontiers of Environmental Science & Engineering (FESE). To date, FESE has received more than 5500 submissions from more than 80 countries and our acceptance rate is ~20%. FESE has also been providing a communication and development platform by increasing its editorial board, organizing conferences, and setting up awards. We are grateful for the support from authors, reviewers, readers, and editorial colleagues to jointly make FESE an internationally recognized journal in the Environmental Science and Engineering field. FESE is becoming an important and irreplaceable forum on environmental issues. Nowadays, environmental issues have attracted tremendous attention and they call for solutions to combat pollution, to achieve carbon neutrality, to tackle climate change, and to promote sustainable development. Accordingly, research is tackling more complex challenges and FESE is conveying knowledge and technological solutions to address these challenges. FESE will implement several new initiatives in 2022. First, FESE will further increase the quality of its publications and its services to the Environmental Science and Engineering community. Second, FESE will publish articles in a more timely fashion by publishing them on a monthly basis. Third, we will introduce a new article style, “Opinion,” that will broaden our perspectives and focus. Fourth, we have been launching the first Young Talent Award which will recognize promising investigators. 2022 will certainly be a year full of passion and expectations. Hereby, we hope that FESE will march toward a higher level with the hard work from editorial board members and editorial office, the continuous support from authors and reviewers, and the close collaborations among Chinese Academy of Engineering, Tsinghua University, Higher Education Press, Springer, and other organizations. Finally, we wish you all a happy, healthy, and fruitful 2022!

摘要:

This study aimed to evaluate the effects of thyroid hormone supplementation on growth rate of children with idiopathic short stature (ISS) and low-normal serum free thyroxine FT4 who were receiving growth hormone therapy. We selected 64 prepubertal children with FT4 levels in the lowest third of the normal range as the lower FT4 group, and these children were divided randomly into two subgroups: L-thyroxine (L-T4)-treated subgroup was treated with L-T4 (0.5–3.0 g/(kg·d)) from the beginning of the study, and the non-L-T4-treated subgroup received placebo. We also selected 39 ISS children with FT4 in the upper two-thirds of the normal range as the higher FT4 group. During the first year, the lower FT4 group featured lower FT3, FT4, thyroid stimulating hormone (TSH), and insulin-like growth factor-I standard deviation score (IGF-I SDS) and significantly lower height velocity (HV) compared with the higher FT4 group. However, in the lower FT4 group, the L-T4-treated subgroup presented higher FT4, FT3, TSH, and IGF-I SDS concentrations and significantly higher HV compared with children in the non-L-T4-treated subgroup. In children with ISS, the negative effect of thyroid hormone deficiency on growth rate should be considered when FT4 level lies in the low-normal range prior to recombinant human growth hormone treatment.

Lung function and air pollution exposure in adults with asthma in Beijing: a 2-year longitudinal panel

《医学前沿(英文)》 2022年 第16卷 第4期   页码 574-583 doi: 10.1007/s11684-021-0882-1

摘要: The effect of air pollution on the lung function of adults with asthma remains unclear to date. This study followed 112 patients with asthma at 3-month intervals for 2 years. The pollutant exposure of the participants was estimated using the inverse distance weight method. The participants were divided into three groups according to their lung function level at every visit. A linear mixed-effect model was applied to predict the change in lung function with each unit change in pollution concentration. Exposure to carbon monoxide (CO) and particles less than 2.5 micrometers in diameter (PM2.5) was negatively associated with large airway function in participants. In the severe group, exposure to chronic sulfur dioxide (SO2) was negatively associated with post-bronchodilator forced expiratory flow at 50%, between 25% and 75% of vital capacity % predicted (change of 95% CI per unit: −0.34 (−0.55, −0.12), −0.24 (−0.44, −0.03), respectively). In the mild group, the effect of SO2 on the small airways was similar to that in the severe group, and it was negatively associated with large airway function. Exposure to CO and PM2.5 was negatively associated with the large airway function of adults with asthma. The negative effects of SO2 were more evident and widely observed in adults with severe and mild asthma than in adults with moderate asthma. Patients with asthma react differently to air pollutants as evidenced by their lung function levels.

摘要:

Systematic reviews and meta-analyses are playing an increasingly important role in clinical research and practice. This study aimed to measure the scientific production of systematic review and meta-analysis from the three major regions of China: the Mainland (ML), Hong Kong (HK), and Taiwan (TW). English articles on systematic review and meta-analysis from ML, HK, and TW from 2001 to 2010 were retrieved from the PubMed database. The total number of articles, impact factors (IF), and articles published in high-impact journals were conducted for quantity and quality comparisons among the three regions. There were 1 587 published articles from ML (1 292), HK (203), and TW (92) during the past ten years. The annual total numbers of articles in the three regions increased significantly from 2001 to 2010 (from 13 to 677). The number of articles from ML has exceeded that from TW since 2001, and surpassed that from HK in 2003. The accumulated IF of articles from ML (3 488.24) was higher than those from HK (493.16) and TW (216.39). HK had the highest average IF of 3.31, followed by ML of 2.90 and TW of 2.85. Researchers from HK published a larger proportion of papers in high-impact journals than those from ML and TW. The Cochrane Database of Systematic Reviews was the most popular journal in China. Chinese authors have been very active to enhance the systematic review and meta-analysis research over the past ten years, especially in ML. The gap between ML and the other two regions has been narrowed. But there is still considerable room for Chinese authors to improve their studies on systematic review and meta-analysis.

Ammonia adsorption on graphene and graphene oxide: a first-principles study

Yue PENG, Junhua LI

《环境科学与工程前沿(英文)》 2013年 第7卷 第3期   页码 403-411 doi: 10.1007/s11783-013-0491-6

摘要: Motivated by the recent realization of graphene sensor to detect gas molecules that are harmful to the environment, the ammonia adsorption on graphene or graphene oxide (GO) was investigated using first-principles calculation. The optimal adsorption and orientation of the NH molecules on the graphene surfaces were determined, and the adsorption energies ( ) as well as the Mulliken charge transfers of NH were calculated. The for the graphene are small and seem to be independent of the sites and orientations. The surface epoxy or hydroxyl groups can promote the adsorption of NH on the GO; the enhancement of the for the hydroxyl groups is greater than that for the epoxy groups on the surface. The charge transfers from the molecule to the surfaces also exhibit the same trend. The Br?nsted acid sites and Lewis acid sites could stably exist on the GO with surface hydroxyl groups and on the basal, respectively.

摘要: From 2006 to 2009, the aggregate energy intensity of China fell by 14.38%, which means that China has made substantial progress towards its goal of achieving approximately a 20% reduction in energy intensity during the period of the 11th FYP (Five-Year Plan). This paper describes some new properties of the mechanism for the decrease in China’s energy intensity since the beginning of the 11th FYP. First, compared with the period of the 10th FYP, technical, structural, and residential energy-savings have been improved to a certain extent. Secondly, unlike the dynamic mechanism before 2000, technical energy savings have been the main driver of momentum since the beginning of the 11th FYP. Next, although structural energy savings are not the main factor, they are still a key factor for the decrease in energy intensity. Finally, residential energy savings are still a stable driver of momentum for the decline in China’s energy intensity.

摘要: Malaria is highly prevalent in Nigeria and accounts for approximately 40% of global malaria mortality. However, most reports on severe malaria in Nigeria are from hospital-based studies without accurate information from communities; thus, malaria-related deaths in the community are left untracked. This study aimed to describe the prevalence and pattern of severe malaria in a community in Northwestern Nigeria. A cross-sectional study was conducted among 2–10-year-old children in Sokoto, in August and December 2016, to determine the endemicity of malaria based on Plasmodium falciparum prevalence rate (PfPR2-10) and to describe the disease pattern. Severe malaria was diagnosed according to the World Health Organisation criteria. Data were described using Stata version 15. The prevalence of non-anaemia severe malaria was higher than expected (2.6%), considering the endemicity pattern which was mesoendemic based on a PfPR2-10 of 34.8%. The mean age of children with severe malaria was 3.73 years, and the male–female ratio was 2:1. However, 54.0% of the patients had hyperparasitaemia. A relatively high prevalence of non-anaemia severe malaria was found in Wamakko. This finding suggests the need to identify and treat cases in the community using modifications of current strategies, particularly seasonal malaria chemoprophylaxis.

摘要: Toxic elements in the atmosphere can enter and accumulate in the human body, seriously impacting human health. In this study, we analyzed a 14-year (1995–2008) measurement of three toxic elements (As, Cd and Cr) in PM in Hong Kong, China. The pollution of these toxic elements in Hong Kong was not serious. The trend analysis showed that As and Cr in PM increased at a statistically significant level ( <0.05) during the 14-year period, while the Cd in PM did not change significantly. Typical seasonal variations were observed for all three toxic elements, largely in relation to the Asian monsoon. Hourly 10-day backward trajectories were computed and categorised into four groups. The continental air masses showed much higher concentrations of the three toxic elements than the marine air masses. The abundances of As and Cd in the PM were much higher in the continental air masses than those in the marine air masses, while the abundances of Cr showed an opposite pattern. The trends of the three toxic elements in East China’s air mass were consistent with those in the overall data set of Hong Kong. Examination of the toxic element data recorded at urban sites and a roadside site also indicated a large contribution of external air masses to particulate As and Cd in Hong Kong. These results suggest that the long-range transport from the mainland of China is the dominant contributor to particulate As and Cd, while both local and long-distance sources determine the particulate Cr in Hong Kong.
