Journal of Geoscience and Environment Protection 2024年第1期12卷 33-50页

作者： Justus Renatus Mbawala Huixin Li Daudi Mikidadi Ndabagenga Jiani Zeng Peter Nicky Mlonganile Collaborative Innovation center on Forecast and Evaluation of Meteorological Disasters/Key Laboratory of Meteorological Disaster Ministry of Education School of Atmospheric Sciences Nanjing University of Information Science and Technology Nanjing China National Meteorological Training Centre Kigoma Tanzania Tanzania Meteorological Authority (TMA) Forecasting Office Kilimanjaro International Airport (KIA) Kilimanjaro Tanzania

Extreme weather and climatic phenomena, such as heatwaves, cold waves, floods and droughts, are expected to become more common and have a significant impact on ecosystems, biodiversity, and society. Devastating disasters are mostly caused by record-breaking extreme events, which are becoming more frequent throughout the world, including Tanzania. A clear global signal of an increase in warm days and nights and a decrease in cold days and nights has been observed. The present study assessed the trends of annual extreme temperature indices during the period of 1982 to 2022 from 29 meteorological stations in which the daily minimum and maximum data were obtained from NASA/POWER. The Mann-Kendall and Sen slope estimator were employed for trend analysis calculation over the study area. The analyzed data have indicated for the most parts, the country has an increase in warm days and nights, extreme warm days and nights and a decrease in cold days and nights, extreme cold days and nights. It has been disclosed that the number of warm nights and days is on the rise, with the number of warm nights trending significantly faster than the number of warm days. The percentile-based extreme temperature indices exhibited more noticeable changes than the absolute extreme temperature indices. Specifically, 66% and 97% of stations demonstrated positive increasing trends in warm days (TX90p) and nights (TN90p), respectively. Conversely, the cold indices demonstrated 41% and 97% negative decreasing trends in TX10p and TN10p, respectively. The results are seemingly consistent with the observed temperature extreme trends in various parts of the world as indicated in IPCC reports.

pplying biodegradable osteosyntheses avoids the disadvantages of titanium osteosyntheses. However, foreign-body reactions remain a major concern and evidence of complete resorption is lacking. This study compared the physico-chemical properties, histological response and radiographs of four copolymeric biodegradable osteo-synthesis systems in a goat model with 48-months follow-up. The systems were implanted subperiosteally in both tibia and radius of 12 Dutch White goats. The BioSorb FX [poly(70LLA-co-30DLLA)], Inion CPS [poly([70–78.5] LLA-co-[16–24]DLLA-co-4TMC)], SonicWeld Rx [poly(DLLA)], LactoSorb [poly(82LLA-co-18GA)] systems and a negative control were randomly implanted in each extremity. Samples were assessed at 6-, 12-, 18-, 24-, 36-, and 48-month follow-up. Surface topography was performed using scanning electron microscopy (SEM). Differential scanning calorimetry and gel permeation chromatography were performed on initial and explanted samples. Histological sections were systematically assessed by two blinded researchers using (polarized) light microscopy, SEM and energy-dispersive X-ray analysis. The SonicWeld Rx system was amorphous while the others were semi-crystalline. Foreign-body reactions were not observed during the complete follow-up. The SonicWeld Rx and LactoSorb systems reached bone percentages of negative controls after 18 months while the BioSorb Fx and Inion CPS systems reached these levels after 36 months. The SonicWeld Rx system showed the most predictable degradation profile. All the biodegradable systems were safe to use and well-tolerated (i.e., complete implant replacement by bone, no clinical or histological foreign body reactions, no [sterile] abscess formation, no re-interventions needed), but nanoscale residual polymeric fragments were observed at every system’s assessment.

背景手术期间输入红细胞与原位肝移植患者的不良预后有关。实验性研究已经证实血小板可导致肝脏再灌注损伤，但是输注同种异体血小板对患者预后的影响尚未见详细的研究。本研究中，我们评估了不同血液制品对原位肝移植患者预后的影响。方法对1989年到2004年之间行第1次原位肝移植的433例患者与预后有关的29个变量，包括血液制品输注等进行了研究。各项数据采用单因素和多因素逐步Cox比例风险模型法进行了统计分析，并对血小板输注采用校正倾向评分分析法以控制使用血液制品中的选择性偏差。结果输注血液制品的移植患者比例从1989～1996年的100％下降到1997～2004年的74％。在单因素和多因素分析中，移植的指征、输注血小板和红细胞是预测移植患者1年生存率最重要的因素。这些危险因素与终末肝病分型评分和garnofsky评分等已被公认的肝脏疾病指数无关。输注血小板和红细胞呈剂量依赖性影响1年生存率，输注每单位血小板的危险比为1．377（P=0．01），输注每单位红细胞的危险比为1．057（P=0．001）。经校正倾向性评分分析证实，血小板输注对生存率有负面影响。结论本项回顾性研究表明，除红细胞外，血小板输注也是影响原位肝移植术后存活的独立危险因素。这些研究结果对肝移植受体的临床液体输注具有重要意义。
