本文综述了当前运动对Lepfin效应的主要研究工作。Lepfin是近年发现的能量平衡调节的激素,是Ob基因的表达产物。运动对Leptin水平的影响表现在:长期有氧运动可降低血Lepfin浓度,减少脂肪组织Ob基因的表达,而一次性运动对Lepdn表达和其血中浓度的影响研究结果不一。运动的这些效应可能依赖于运动负荷量和运动时间。 相似文献

Serum creatinine does not distinguish between various causes of graft dysfunction. Serial assay of proximal tubular enzymes
N-Acetyl-D-glucosaminidase (NAG), Alanine aminopeptidase (AAP) and Gamma glutamyl transferase (GGT) in urine was done to assess
their usefulness in distinguishing various causes of graft dysfunction. Daily serum creatinine and enzymuria were measured
in 32 consecutive renal allograft recipients for first 15 postoperative days. Graft dysfunction was defined as >20% increase
in serum creatinine and >100% increase in enzymuria over the baseline. The diagnosis of graft dysfunction was based upon clinical
criteria, ultrasonography, cyclosporin trough level, allograft biopsy, response to anti-rejection therapy and alteration of
cyclosporin dosage. Fifteen episodes of graft dysfunction were identified in 15 patients. The sensitivity and specificity
of the enzymes (NAG, AAP and GGT) for predicting graft dysfunction were 87.5%, 86.9%, 88.5% and 98.2%, 98.2%, 97.9% respectively.
There was a significant increase in enzymuria during acute tubular necrosis (ATN) and acute rejection episode compared to
cyclosporin nephrotoxicity (p<0.01). Enzymuria assay provides a simple, reliable and noninvasive method to distinguish cyclosporin
nephrotoxicity from acute tubular necrosis and acute rejection in renal allograft recipients. 相似文献

Vitamin A status was measured in 50 pre-school children with acute and persistent diarrhoea. It was measured by (a) Fluorometric
micromethod and (b) Conjunctival impression cytology (CIC). The results were compared with 25 normal children. Vitamin A status
was lower in children with persistent diarrhoea whereas the results were comparable between the children with acute diarrhoea
and control subjects. 相似文献

目的:探讨急性酒精中毒患者的护理效果。方法:回顾性分析该院急诊科2013年6月至12月收治的35例急性酒精中毒患者的救治和护理效果。结果:35例急性酒精中毒患者,有31例均在急诊科1~2天内治愈;2例并发胃出血、1例并发吸入性肺炎、1例并发右上肢桡骨骨折,经抢救病情稳定后转科。另外,针对不同的患者,采取了不同的护理措施,均获得了满意的效果。结论:急性酒精中毒患者除了应紧急抢救,防治并发症之外,还应加强对患者的护理,这不仅能提高治疗效果,而且能增强患者的生活信心,提高生活质量,有助于控制和预防复发。 相似文献

为了筛选得到对玉米茎腐病菌室内抑制活性较高的杀菌剂,采用菌丝生长速率法测定了不同化学杀菌剂对肿囊腐霉菌(Pythium inflatum)和禾谷镰孢菌(Fusarium graminearum)2种致病菌的抑制活性。结果表明,丙森锌、雷多米尔·锰锌、烯酰吗啉和氟吡菌胺4种杀菌剂对肿囊腐霉菌的毒力较高,其EC50。分别为O.40μgZmL、0.47μg/mL、0.61μg/mL和2.64μg/mL;禾谷镰孢菌对咯菌腈、戊唑醇和多菌灵3种杀菌剂的敏感性较高,其EC50分别为0.06μg/,mL、0.32μg/mL和0.85μg/mL,苯醚甲环唑和腈菌唑2种杀菌剂对禾谷镰孢菌的抑制活性稍差,其EC50。分别为1.71μg/mL和1.80μg/mL。上述筛选到的9种药剂对玉米茎腐病菌的室内抑菌活性较高,可以作为供试药剂进行大田药效试验。 相似文献

Political polarization remains perhaps the “greatest barrier” to effective COVID-19 pandemic mitigation measures in the United States. Social media has been implicated in fueling this polarization. In this paper, we uncover the network of COVID-19 related news sources shared to 30 politically biased and 2 neutral subcommunities on Reddit. We find, using exponential random graph modeling, that news sources associated with highly toxic – “rude, disrespectful” – content are more likely to be shared across political subreddits. We also find homophily according to toxicity levels in the network of online news sources. Our findings suggest that news sources associated with high toxicity are rewarded with prominent positions in the resultant network. The toxicity in COVID-19 discussions may fuel political polarization by denigrating ideological opponents and politicizing responses to the COVID-19 pandemic, all to the detriment of mitigation measures. Public health practitioners should monitor toxicity in public online discussions to familiarize themselves with emerging political arguments that threaten adherence to public health crises management. We also recommend, based on our findings, that social media platforms algorithmically promote neutral and scientific news sources to reduce toxic discussion in subcommunities and encourage compliance with public health recommendations in the fight against COVID-19. 相似文献
