对“训练负荷应大于比赛负荷”的两点质疑：兼论负荷安排的经济性原则   总被引：4，自引：0，他引：4  

刘建和 《成都体育学院学报》1996,22(1):84-87

在肯定“训练负荷应大于比赛负荷”口号的巨大历史功效的同时，对其中两点模糊不清之处提出了质疑：训练负荷能否在所有构成因素方面均大于比赛负荷？大于之处大多少为宜？之后，初步论证了负荷安排中经济性原则的科学性。  相似文献

崔丽萍  史大卓  杨锡让 《体育学刊》2002,9(2):29-30

目的：通过观察不同剂量CLT和FT对于垂体后叶素引起的急性心肌缺血大鼠心电图的影响，探讨其抗大鼠急性心肌缺血、保护心肌的作用。方法：灌胃给药7d，尾静脉注射垂体后叶素2次．并描记心电图。结果：第2次注射后15min，造模组和FT组ST-T的升高超过1mV．出现急性心肌缺血，并且心肌缺血阳性率升高；CLT小、大剂量组ST—T升高值明显降低，心肌缺血阳性率明显减少。结论：CLT有预防和减轻大鼠急性心肌缺血的作用，FT没有此作用。  相似文献   

运动负荷与生理负荷的定位与解析   总被引：12，自引：3，他引：9  

王广虎  胡健 《成都体育学院学报》1996,22(4):96-96,22(4)

运动负荷与生理负荷是两个有区别的不同概念。生理负荷是描述人体系统机能状况改变的内部参量，其性质是一种状态量。运动负荷是描述人体行为动态过程的外部参量，其性质是一种过程量。运动内容，运动强度，运动数量，运动密度是构成运动负荷的基本要素  相似文献

Ecological principle meets cancer treatment: treating children with acute myeloid leukemia with low-dose chemotherapy

Standard chemotherapy regimens for remission induction of pediatric acute myeloid leukemia (AML) are associated with significant morbidity and mortality. We performed a cohort study to determine the impact of reducing the intensity of remission induction chemotherapy on the outcomes of selected children with AML treated with a low-dose induction regimen plus granulocyte colony stimulating factor (G-CSF) (low-dose chemotherapy (LDC)/G-CSF). Complete response (CR) after two induction courses was attained in 87.0% (40/46) of patients receiving LDC/G-CSF. Post-remission therapy was offered to all patients, and included standard consolidation and/or stem cell transplantation. During the study period, an additional 94 consecutive children with AML treated with standard chemotherapy (SDC) for induction (80/94 (85.1%) of the patients attained CR after induction II, P = 0.953) and post-remission. In this non-randomized study, there were no significant differences in 4-year event-free (67.4 vs. 70.7%; P = 0.99) and overall (70.3 vs. 74.6%, P = 0.69) survival in the LDC/G-CSF and SDC cohorts, respectively. After the first course of induction, recovery of white blood cell (WBC) and platelet counts were significantly faster in patients receiving LDC/G-CSF than in those receiving SDC (11.5 vs. 18.5 d for WBCs (P < 0.001); 15.5 vs. 22.0 d for platelets (P < 0.001)). To examine the quality of molecular response, targeted deep sequencing was performed. Of 137 mutations detected at diagnosis in 20 children who attained hematological CR after two courses of LDC/G-CSF (n = 9) or SDC (n = 11), all of the mutations were below the reference value (variant allelic frequency <2.5%) after two courses, irrespective of the treatment group. In conclusion, children with AML receiving LDC/G-CSF appear to have similar outcomes and mutation clearance levels, but significantly lower toxicity than those receiving SDC. Thus, LDC/G-CSF should be further evaluated as an effective alternative to remission induction in pediatric AML.  相似文献   

Review:Study progress in therapeutic effects of traditional Chinese medicine monomer in severe acute pancreautis     

ZHANG Xi-ping  LIU Da-ren  SHI Yan 《Journal of Zhejiang University. Science. B》2007,8(2)

Severe acute pancreatitis (SAP) is a common acute abdomen clinical problem characterized by high mortality, multiple complications, complicated pathogenesis and difficult treatment. Recent studies found traditional Chinese medicine (TCM)monomers have markedly good effect for treating SAP. Many TCM monomers can inhibit pancreatin, resist inflammation, improve microcirculation and immunoloregulation, etc. to block the pathological progress of SAP in multiple ways, reduce complications and lower mortality with rapid effects. It is significant for enhancing SAP treatment to deeply understand the current situation in TCM monomers for treating SAP and take precious references therein. This article summarizes the treating effects and mechanisms of TCM monomers for SAP in recent years.  相似文献   

劝转与涅檠——从《狂人日记》与《凤凰涅榘》看鲁迅和郭沫若的救世思想     

王雨海 《信阳师范学院学报(哲学社会科学版)》2005,25(4):94-98

鲁迅与郭沫若通过狂人和凤凰形象的塑造对当时社会进行了深刻的解剖和批判，展示了早期先进知识分子的特点和作用，同时，他们提出了拯救社会的方式和方法：鲁迅主张通过劝转使人吃人的社会过渡到真正的人的社会；郭沫若则主张通过涅榘让旧世界毁灭，诞生一个崭新的世界。这两种方式体现了鲁迅与郭沫若不同的主体态度和人生选择，也显现了他们在救世思想上的分歧和不同。  相似文献   

青年学生四肢急性运动损伤救治和预防研究     

王国基熊茂湘  张轶群尹建文 《娄底师专学报》2006,(6):95-97

分析4年收治的235例大、中学生四肢急性运动损伤，发现75．3％为轻微皮肤和软组织挫、擦、裂伤，18．3％（43／235）遗留瘢痕；24、7％属于高能量损伤导致肌腱韧带和骨质、关节严重损伤，5．1％（12／235）遗留活动功能障碍，认为缺乏安全保护意识是导致损伤的主要原因，而及时、正确的救治才能有效减少并发症和后遗症的发生，切实改善运动场地条件、加强保护、防止暴力冲撞、维持良好的纪律，才是预防运动损伤的基本措施。  相似文献   

Relationships between colleague ratings and faculty compensation     

John Muffo 《Research in higher education》1979,10(1):25-35

Rankings of graduate and professional programs have become commonplace since Cartter's study for the American Council on Education was published in 1966. Much of the research up to the present has focused on discovering proxy variables, such as departmental size, which correspond to departmental ratings, as well as observing how the ratings of departments change over time. This study examines the relationship between the peer ratings reported by Roose and Andersen in 1970 and resource allocation patterns, represented by average salary figures, among fifty major American universities. It also shows the relationship of these ratings and other resource allocation measures within one of the fifty institutions. Results indicate that among the fifty universities, average salaries are higher at the highly rated institutions than at the lower rated ones, with senior professors being the chief beneficiaries of the higher wage scales. Similarly, within one institution the senior professors of higher ranked departments are better paid, compared to their junior colleagues, than those of lower rated departments. The higher rated departments share commonalities as to proportion of senior professors and teaching load assignments as well. Both across and within universities, departments found to be prestigious by Roose and Andersen do tend to exhibit common characteristics concerning resource allocation procedures.Presented at the Annual Forum of the Association for Institutional Research, Houston, Texas, May 1978.  相似文献   

Study progress on mechanism of severe acute pancreatitis complicated with hepatic injury   总被引：4，自引：0，他引：4  

ZHANG Xi-ping  WANG Lei  ZHANG Jie 《Journal of Zhejiang University. Science. B》2007,8(4):228-236

Study on the action mechanism of inflammatory mediators generated by the severe acute pancreatitis(SAP) in mul-tiple organ injury is a hotspot in the surgical field.In clinical practice,the main complicated organ dysfunctions are shock,res-piratory failure,renal failure,encephalopathy,with the rate of hepatic diseases being closely next to them.The hepatic injury caused by SAP cannot only aggravate the state of pancreatitis,but also develop into hepatic failure and cause patient death.Its complicated pathogenic mechanism is an obstacle in clinical treatment.Among many pathogenic factors,the changes of vasoac-tive substances,participation of inflammatory mediators as well as OFR(oxygen free radical),endotoxin,etc.may play important roles in its progression.  相似文献
