OBJECTIVE: To assess the effects of prolonged strenuous exercise in the form of a half-ironman (HI) race (2 km swim, 90 km bike ride and a 21 km run) on left ventricular systolic function. METHODS AND RESULTS: The study participants consisted of nine male triathletes (mean age +/- SD 32+/-5 years) who competed in the Great White North HI race. Two-dimensional transthoracic echocardiograms were obtained two to three days before the HI (prerace), immediately after completion of the HI (postrace) and 24 h after cessation of exercise. Compared with before the race, performing an HI was associated with a decline in systolic blood pressure (prerace 127.2+/-15.0 mmHg compared with after the race 116.1+/-10.2 mmHg, P<0.05), the systolic blood pressure to end-systolic cavity area ratio (a surrogate for left ventricular contractility - prerace 14.3+/-3.0 mmHg/cm(2) compared with postrace 11.0+/-2.2 mmHg/cm(2), P<0.05) and the fractional area change (prerace 54.1+/-3.8% compared with postrace 47.4+/-5.5%, P<0.05). There was also a concomitant increase in heart rate (prerace 56.3+/-9.4 beats/min compared with postrace 74.1+/-10.7 beats/min, P<0.05), the end-systolic cavity area (prerace 9.2+/-2.2 cm(2) compared with postrace 10.8+/-1.9 cm(2), P<0.05) and the end-systolic cavity area to end-systolic myocardial area ratio (prerace 0.39+/-0.08 compared with postrace 0.51+/-0.1, P<0.05), which returned toward baseline values 24 h after cessation of the HI. CONCLUSIONS: Performing an HI appears to be associated with a transient impairment in left ventricular contractility and a subsequent decline in left ventricular systolic function that tends to return toward normal values within 24 h after cessation of exercise. 相似文献

BACKGROUND/AIMS: To predict the occurrence of postoperative liver failure after hepatectomy, the clinical significance of monitoring alkaline phosphatase (ALP) has been studied, and the relationship between the change of total bilirubin and the level of ALP or gamma-glutamyl transpeptidase (gamma-GTP) after hepatectomy was evaluated. METHODOLOGY: The 163 patients, who underwent hepatectomy at our institute for the past 12 years, were divided into three groups according to the postoperative events. HF consisted of 5 patients with liver failure, HB showed the postoperative high bilirubinemia (over 5mg/dL) in 13 cases and GP were 145 cases without any postoperative problems. RESULTS: 1. The postoperative highest level of total bilirubin (T-Bil) correlated with the decreasing rate of ALP, prothrombin time (PT), total cholesterol (T-CHO) or gamma-GTP and total blood loss (p<0.01). 2. The level of ALP decreased after hepatectomy significantly and the decreasing rate was serious in HB and HF (p<0.05). 3. The recovering time to preoperative level of ALP was clearly shorter in GP than in HB and HF. 4. The level of ALP and gamma-GTP at the point where the level of T-Bil increased over 5mg/dL, was useful to distinguish between HF and HB. 5. The good correlation between postoperative level of ALP and gamma-GTP was noted. The decreasing levels of ALP and gamma-GTP were found to be critical below 80% and 55% after bisegmentectomy. Furthermore, the recovered levels of ALP and gamma-GTP were important to distinguish between HF and HB. CONCLUSIONS: Monitoring the ALP level was indicated to be useful to estimate the postoperative course of bilirubin. 相似文献

Marathon racing is a strenuous exercise that has a profound effect on many laboratory parameters. Participants in marathon races may require abstinence of exercise and the performance of laboratory assays several days after the event. The aim of this study was to evaluate the possible changes in blood cell count and biochemical parameters observed in participants in a marathon 3 days before and 3 days after and before and immediately after a cardiopulmonary exercise test. Incremental cycle ergometry up to maximal capacity was performed in 7 marathon runners, 3 days before and 3 days after the race. The % peak oxygen consumption (peak %VO2) achieved was statistically significantly lower after than before the race (p = 0.02). No statistically significant differences were observed in cardiac frequency (p = 0.148) or blood cell count (p = 0.501). Also, the concentration of sodium, potassium, calcium, magnesium, lactate dehydrogenase (LDH), phosphocreatine kinase (CPK) and glucose, measured before and immediately after the pulmonary exercise test, did not differ significantly (p < 0.5). A significant percentage of the laboratory results were outside the standard reference rates. According to our data, exercise performance, as expressed by peak %VO2, continued to be decreased in marathon runners 3 days after the race. The blood cell count and biochemical parameters did not differ significantly but many marathon runners were outside the standard reference rates. Unfortunately, only 7 subjects were available for this study. Further studies with larger samples and with samples obtained at multiple times during and after exercise are needed to clarify the effects of long-distance running. 相似文献

Delayed effects of prolonged exercise on serum lipoproteins 总被引:2,自引:0,他引:2
The delayed lipoprotein changes after a 3-hour running test were examined in 14 moderately trained young male subjects. Fasting blood samples were obtained one day before, immediately before, and one, two, and four days after the race. Nonfasting samples were collected immediately after, one, and three hours after exercise. Three hours after the race, the ratio of unesterified cholesterol to cholesteryl esters was significantly increased, and one and two days after the race it was significantly decreased compared to the preexercise value. The HDL2/HDL3 ratio, measured by density-gradient ultracentrifugation was one and three hours after the running significantly elevated. However, no redistribution of the HDL2/HDL3 cholesterol ratio determined by a precipitation method with polyanions was found at this time. One day postexercise HDL cholesterol rose significantly above the preexercise value, and this was associated with an elevation of the HDL3 subfraction. On the following day a significant increase of HDL2 cholesterol and the HDL2/HDL3 cholesterol ratio was found. The apolipoproteins A-I, A-II, and B, measured by radial immunodiffusion, did not change during the first hours and the first two days after the race. On the second postexercise day the Lp(a) lipoprotein rose significantly above the preexercise value. Compared with the preexercise level the LCAT activity was significantly elevated three hours after the race and significantly decreased two days later. The present study suggests that during the first few days after prolonged exercise a number of plasma lipoprotein changes take place that are similar to those observed after a period of physical training. 相似文献

Changes in plasma leptin and insulin action with resistive training in postmenopausal women 总被引:4,自引:0,他引:4
OBJECTIVE: To determine the effects of 16 weeks of resistive training alone (RT) and with weight loss (RT+WL) on insulin action, plasma leptin concentrations and leptin's relationship to beta-cell sensitivity to glucose, resting metabolic rate (RMR), and plasma catecholamines in older women. SUBJECTS: Fifteen obese postmenopausal women aged 50-69 y. MEASUREMENTS: Body composition (by dual-energy X-ray absorptiometry), RMR (by indirect calorimetry), insulin action (by 2 h hyperglycemic clamps; 7.9 mmol/l above basal plasma glucose levels), plasma leptin and insulin (by RIA), and plasma catecholamines (by enzymatic methods). RESULTS: RT and RT+WL resulted in significant improvements in muscular strength (P<0.01) with no changes in maximal oxygen consumption. Body weight, fat mass and percent body fat did not change with RT, but decreased with RT+WL (P<0.001). Fat-free mass and RMR increased after training when both groups were combined (P<0.05). The insulin response during the last 20 min of the 2 h hyperglycemic clamps decreased 16% after RT (P=0.05), 43% after RT+WL (P<0.05), and 29% in the entire group (P<0. 01) without any changes in glucose utilization. Plasma leptin levels did not change after RT, but decreased by 36% after RT+WL (P<0.05). Baseline leptin levels correlated with body weight (r=0.68, P<0.01), body fat mass (r=0.77, P<0.001), and RMR (kcal/d; (r=0.69, P<0.005), but not with baseline norepinephrine or epinephrine levels. Plasma leptin levels correlated with basal insulin (r=0.73, P<0.005), and approached significance with the 0-10 min and 100-120 min insulin response to hyperglycemia before training (both r=0.51, P=0.07). In the entire group, the change in insulin response from 100-120 min during the clamp correlated with the change in leptin levels (r=0.60, P<0.05), but this was not independent of changes in fat mass. CONCLUSIONS: Although changes in leptin levels were not related to changes in RMR or plasma catecholamines after RT with and without weight loss, the increase in insulin action after training and weight loss may be related to the decrease in leptin levels that were mediated by the loss of body fat in the obese, postmenopausal women.

Background
While the promotion of health-related fitness is thereby widespread, less focus is currently being given on the biological influence that physical activity might exert on results of laboratory testing. As such, this study was undertaken to assess the kinetics of liver injury markers following physical exercise.Design and methods
Total and direct bilirubin as well as the activity of biochemical markers of liver injury including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), gamma-glutamyl transpeptidase (GGT) and creatine kinase (CK), were measured before and after a half-marathon.Results
Significant increases occurred for GGT, AST, LDH, CK, total and direct bilirubin immediately after the run. AST, LDH, CK, total and direct bilirubin were still increased 24 h thereafter, whereas GGT decreased after 6 h. None of the athletes exceed the upper reference limit for ALT, ALP and GGT, whereas significant variations were instead observed for LDH, AST, CK, total and direct bilirubin.Conclusions
Taken together, the results of our prospective investigation clearly attest that an acute bulk of aerobic physical exercise, such as a half-marathon, might produce significant changes in the activity of traditional biomarkers of liver injury, which should be carefully considered when investigating physically active individuals undergoing laboratory testing. 相似文献13.

OBJECTIVE: The time course of the immediate change in bone turnover after parathyroidectomy (PTX) for primary hyperparathyroidism (PHPT) is not clear. It is uncertain whether circulating interleukin-6 (IL-6) plays a role in mediating the acute withdrawal of the effects of parathyroid hormone (PTH) on bone turnover after PTX. The aims of this study were to determine the time course of immediate changes in biochemical markers of bone turnover after PTX and whether circulating IL-6 is involved in the immediate changes of bone turnover after PTX. DESIGN AND METHODS: IL-6 and bone turnover markers were measured in eight women (aged 55+/-11 years, mean+/-s.d. ) with PHTP at baseline and at 1-2h, and 1, 2, 5, 7 and 12 days after PTX. We compared the results with those from eight individually matched women (healthy controls) and five subjects undergoing major surgery (surgical controls). RESULTS: At baseline, serum levels of IL-6 and bone turnover markers were higher in PHPT than those in healthy controls (P<0.05). Serum levels of procollagen propeptides increased by 22 and 27% at days 2 and 5, respectively, compared with baseline (P<0.05). Serum tartrate-resistant acid phosphatase decreased by 2 days after PTX, and urinary collagen crosslinks decreased significantly by 21-41% within 24h (P<0.05). Serum IL-6 levels increased immediately in both PHPT and surgical controls at postoperative follow-up (repeated measures ANOVA). CONCLUSIONS: (1) PTX decreases bone resorption immediately and (2) circulating IL-6 is not involved in the changes in bone turnover immediately after PTX. 相似文献

BACKGROUND/AIMS: To examine whether serum hepatocyte growth factor and interleukin-6 levels are early parameters of postoperative liver dysfunction after hepatectomy. METHODOLOGY: The serum levels of hepatocyte growth factor and interleukin-6 were measured in 16 hepatectomized patients on the day of surgery (before surgery, immediately after hepatectomy, after completion of surgery) and on postoperative days 1, 3, and 5. Serum liver function tests were determined for 14 days after surgery and their results were correlated with serum interleukin-6 and hepatocyte growth factor levels. RESULTS: Serum interleukin-6 and hepatocyte growth factor levels were elevated after surgery and these values were higher in patients who underwent hepatectomy greater than lobectomy in magnitude. The mean maximum value of interleukin-6 appeared on day 0 and was earlier than that of hepatocyte growth factor, which was found on day 1. Serum total bilirubin and alanine aminotransferase levels reached the maximum within 5 days after surgery. Multiple regression analysis showed that serum levels of interleukin-6 and hepatocyte growth factor on day 0 after surgery were significantly correlated with the postoperative maximum total bilirubin level (P < 0.0001). The maximum interleukin-6 level but not hepatocyte growth factor significantly correlated with the postoperative maximum bilirubin level (P < 0.02). CONCLUSIONS: Both the serum interleukin-6 and hepatocyte growth factor levels are likely early indicators of postoperative liver dysfunction in patients after hepatectomy. 相似文献

AIM: To investigate the early diagnostic methods of bacterial and fungal infection in patients with chronic cholestatic hepatitis B.METHODS: One hundred and one adult in-patients with chronic hepatitis B were studied and divided into 3 groups:direct bilirubin (DBil)/total bilirubin (TBil)≥0.5, without bacterial and fungal infection (group A, n=-38); DBil/TBil<0.5, without bacterial and fungal infection (group B, n=23),DBil/TBil≥0.5, with bacterial or fungal infection (group C,rr=-40). The serum biochemical index and pulse rate were analyzed.RESULTS: Level of TBil, DBil, alkaline phosphatase (ALP) and DBiI/ALP in group A increased compared with that in group B. The level of ALP in group C decreased compared with that in group A, whereas the level of TBil, DBil and DBiI/ALP increased (ALP: 156+43, 199+68, respectively,P<0.05, TBil: 370+227, 220+206, respectively, P<0.01,DBil: 214+143, 146+136, respectively, P<0.01, DBiI/ALP:1.65+1.05, 0.78+0.70, respectively, P<0.001). The level of DBil and infection affected DBiI/ALP. Independent of theeffect of DBil, infection caused DBiI/ALP to rise (P<0.05).The pulse rate in group A decreased compared with that in group B (63.7+6.4, 77.7+11.4, respectively, P<0.001),and the pulse rate in group C increased compared withthat in group A (81.2+12.2, 63.7+6.4, respectively, P<0.001).The equation (infection=0.218 pusle rate +1.064 DBiI/ALP-16.361), with total accuracy of 85.5%, was obtained from stepwise logistic regression. Pulse rate (≥80/min) andDBiI/ALP (≥1.0) were used to screen infection. The sensitivity was 62.5% and 64.7% respectively, and the specificity was 100% and 82.8% respectively.CONCLUSION: Bacterial and fungal infection deterioratejaundice and increase pulse rate, decrease serum ALP andincrease DBiI/ALP. Pulse rate, DBiI/ALP and the equation(infection=0.218 pusle rate+1.064 DBil/ALP-16.361) arehelpful to early diagnosis of bacterial and fungal infectionin patients with chronic cholestatic hepatitis B. 相似文献

冠状动脉造影术造影剂与肾功能关系的研究 总被引:6,自引:0,他引:6
目的探讨冠状动脉造影术中造影剂对肾功能的影响。方法①按患者所用造影剂的量分成50~100ml组、100~200ml组和>200ml组。②分别测定术前、术后24h、术后48h、术后10d的血尿素氮(BUN)、血肌苷(Cr)、尿微量白蛋白(MAU)、尿β2-微球蛋白(β2MG)的值并进行比较。结果造影后24h、48h尿β2MG与造影前及造影后10d比较有显著性差异(P<0.05),其余指标各时段之间比较无显著性差异(P>0.05)。造影后24h、48h造影剂>200ml组与50~100ml组及100~200ml组之间Cr、MAU及β2MG的变化有显著性差异(P<0.05)。其余各组之间比较无显著性差异(P>0.05)。结论造影剂对肾功能有一定的损害,并且随造影剂剂量的增加其损害加重。 相似文献
