2Semaglutide降低2型糖尿病患者的心脑血管事件风险显示文摘心血管疾病是2型糖尿病患者发生并发症和死亡的主要原因。最近的一些临床试验报告,一种钠-葡萄糖协同转运蛋白-2抑制剂(依帕列净)和一种胰高血糖素样肽-1(GLP-1)类似物(利拉鲁肽),能够改善心血管高风险的2型糖尿病患者的心血管结局。Semaglutide是GLP-1的一种类似物,半衰期长达约1周,可以一周一次皮下注射,但是尚不清楚其对2型糖尿病患者的心血管效应;由于Semaglutide目前处于开发阶段,尚未被批准用于治疗2型糖尿病。Marso SP Bain SC Consoli A 王建中 2016中华肾病研究电子杂志2016,5,5:141
3Effect of preoperative regional artery chemotherapy on proliferation and apoptosis of gastric carcinoma cells显示文摘AIM: To study the effects of preoperative regional arterychemotherapy (PRACT) in inducing growth inhibition andapoptosis of gastric carcinorna (GC) calls.METHODS: TUNEL ( terminal-deoxynucleotidyl-transferaseTdT-mediated dUTP-fluorescein and labeling) method andimmunohistochemical techniques were used to detect thestate of apoptosis and proliferation of GC cells inhistopathologic sections. A total of 110 cases of GC and 68cases of metastatic lymph node with or without PRACT wereadopted. Correlations between apoptosis index (Al),proliferation index (PI) and PRACT and prognosis wereanalysed.RESULTS: The apoptosis index (Al) was significantly higherin the PRACT group (12.5 ‰ + 4.33‰) than in the untreatedgroup (7. 1‰ + 3. 43 ‰, P < 0. 001 ), whereas theproliferation index (PI) in the PRACT group (33.8 % ± 8.8% ) was eignificantly lower than that in untreated group (43.6 % + 12.8 %, P<0.01). Both Al and PI were correlated tothe differentiation degree of GC in PRACT group, the Al inthe differentiated group was higher than that inundifferentiated group (P<0.001), but the PI was lower inthe differentiated group than that of the undifferentiatedgroup ( P < 0.01 ). The Al of GC cells in metastatic lymphnode was also significantly higher in the PRACT group (7.9‰+ 3.41‰) than in the untreated group (3.6 ‰ + 2.93 ‰,P < 0.01 ), though the PI of GC cells in metastatic lymphnodes in the PRACT group (17. 2 % + 6. 8 % ) wassignificantly lower than that in the untreated group (26.7 %+ 9. 3 %, P < 0. 01 ). The severity of histopathologicchanges was significantly higher in the PRACT group than inthe untreated group ( P < 0.05). In addition, postoperativesurveys demonstrated that the 5-year survival rate of GCpatients in the PRACT group was significantly higher than thatof patients in the untreated group (P<0.01).CONCLUSION: Preoperative regional artery chemotherapy(PRACT) showed inhibitory action on the growth of GC cellsmainly through inhibiting proliferation and inducing theapoptosis of tumor cells. PRACT can improve the prognosisof GC patients also.Tao, HQ Zou, SC 2002World Journal of Gastroenterology2002,8,3:49

14Fischer Plots of Wumishan Cyclothems,Precambrian Records of Third-OrderSea-Level Changes显示文摘The Mesoproterozoic Wumishan Formation ((1310 ± 20 ) Ma - (l 207 ± 10) Ma) in Jixian, Tianjin represents a succession of 3 300 meter thick carbonate strata where are the best developed stromatolite biostromes and thrombolite bioherms. These biostromes and bioherms, together with tidal-flat dolomites and muddy dolostones, form Wumishan cyclothems with approximately symmetrical faciessuccession fabrics, which belong to carbonate meter-scale cyclic sequences of peritidal type. These cyclothems are overlain by lagoon dolomitic mudstones and shales and by frequently developed paleosol layers, indicating that the boundary of Wumishan cyclothems is marked by an instantaneously-exposed punctuated surface. Viewed form the regularly vertical stacking patterns of Wumishan cyclothems in long-term sequences, 26 third-order sequences may be discerned in Wumishan Formation. These thirdorder sequences may also be incorporated into six second-order sequences. In order to study the variation range of third-order sea-level changes and the formation period of third-order sequence, 626 cyclothems are discerned in the middle and upper parts of Wumishan Formation where the outcrops are well developed. In terms of the total thickness and the formation period of Mesoproterozoic Wumishan Formation, the crust subsidence rate in the sedimentary period of Wumishan Formation is supposed to be 3 meters at each interval of 100 thousands years. Based on this assumption, Fischer plot might be designed to simulate the third-order sea-level changing pattern.Mei Mingxiang Faculty of Earth Sciences and Mineral Resources, China University of Geosciences, Beijing 100083 Ma Yongsheng China Petrochemical Corporation (SINOPEC), Beijing 100029 Zhou Hongrui Du Benming Luo Zhiqing Guo Qingyin Faculty of Earth Sc 2001Journal of China University of Geosciences2001,12,1:11

16Maize ZmFDR3 localized in chloroplasts is involved in iron transport显示文摘Iron is an essential nutrient for plant metabolism such that Fe-limited plants display chlorosis and suffer from reduced photosynthetic efficiency. Differential display previously identified genes whose expression was elevated in Fe-deficient maize roots. Here,we describe the functional characterization of one of the genes identified in the screen,ZmFDR3 (Zea maize Fe-deficiency-related). Heterologous functional complementation assays using a yeast iron uptake mutant showed that ZmFDR3 functions in iron transport. ZmFDR3 contains a domain found in FliN-proteins of the type III secretion system and is predicted to localize to the thylakoid of plastids. Fluorescence immunocytochemistry showed that ZmFDR3 is localized in the plastids of roots,stems and leaves,with high expression found in guard cell chloroplasts. Transgenic tobacco expressing a 35S-ZmFDR3 construct contains elevated iron content,displays well arranged thylakoid membranes and has photosynthetic indices that are higher than those of the wild type. Together,these results suggest that ZmFDR3 functions in chloroplast iron transport.HAN JianHui1,SONG XiuFang1,LI Peng1,YANG HuiJun2 & YIN LiPing1 1 College of Life Science,Capital Normal University,Beijing 100048,China 2 Department of Biological Sciences,University of South Carolina,Columbia,SC 29208,USA 2009Science China(Life Sciences)2009,52,9:7
17Establishing the presence or absence of chronic kidney disease:Uses and limitations of formulas estimating the glomerular filtration rate显示文摘The development of formulas estimating glomerular filtration rate(eG FR) from serum creatinine and cystatin C and accounting for certain variables affecting the production rate of these biomarkers, including ethnicity, gender and age, has led to the current scheme of diagnosing and staging chronic kidney disease(CKD),which is based on e GFR values and albuminuria.This scheme has been applied extensively in various populations and has led to the current estimates of prevalence of CKD. In addition, this scheme is applied in clinical studies evaluating the risks of CKD and the efficacy of various interventions directed towards improving its course. Disagreements between creatinine-based and cystatin-based e GFR values and between e GFR values and measured GFR have been reported in various cohorts. These disagreements are the consequence of variations in the rate of production and in factors, other than GFR, affecting the rate of removal of creatinine and cystatin C. The disagreements create limitations for all e GFR formulas developed so far. The main limitations are low sensitivity in detecting early CKD in several subjects, e.g., those with hyperfiltration, and poor prediction of the course of CKD. Research efforts in CKD are currently directed towards identification of biomarkers that are better indices of GFR than the current biomarkers and,particularly, biomarkers of early renal tissue injury.Ahmed Alaini Deepak Malhotra Helbert Rondon-Berrios Christos P Argyropoulos Zeid J Khitan Dominic SC Raj Mark Rohrscheib Joseph I Shapiro Antonios H Tzamaloukas 2017World Journal of Methodology2017,7,3:7
