Objective By testing and analyzing the training session RPE, blood lactic acid, urine protein, urine specific gravity and urine pH value of elite woman wrestlers, investigated variation and score differences of the elite woman wrestlers ' five indicators during the four weeks before the elite woman wrestlers championship, to provide a reference for scientific training. Methods 12 elite woman wrestlers completed 24 special training session, 16 strength training session and 12 cardio workout session before four weeks in the elite woman wrestlers championship. The degree of fatigue of athletes in this section were scored within 5 minutes after the end of each training session using Borg 15 subscales, scores were dictated and record. Training session RPE was calculated by the training session time multiplied RPE, daily and weekly training session RPE (sRPE) was counted respectively. The blood lactic acid after intensive training and the daily urine protein, urine specific gravity , urine pH value of elite woman wrestlers were tested using EKF lactateScout appearance of portable blood lactate and blood lactic acid test strip and using Roche Miditron Junior Ⅱsemi-automatic urine analyzer and supporting Comber 10 test M urinary ten test strip, in accordance with standard test procedures.In this study, the measured indicators were analyzed statistically by SPSS19.0 and the measured indicators were expressed as mean±standard deviation(X±S).The total amount of training sRPE that reflected the six weeks was tested by repeated measures analyzing of variance of repeated measures.Differences of the first week and the other five weeks was compared respectively, the level of significance was set up as α=0.05.The correlation of training sRPE, the blood lactic acid after intensive training, urine protein, urine specific gravity and urine pH values was tested by Pearson correlation analysis, P < 0.05 was set up a significant difference,P <0.01 was set up a very significant difference,|r|<0.3 was believed with no correlation. Results The total sRPE of elite woman wrestlers decreased gradually before four weeks in the national championship.Special training session sRPE and strength training session sRPE reach a higher level respectively in the second week and the third week.The aerobic workout sRPE maintained at a lower level during four weeks. The correlation coefficient of elite woman wrestlers' sRPE、urine specific gravity and urine pH value was negative.The correlation coefficient of elite woman wrestlers' sRPE, the blood lactic acid after intensive training and urinary protein was positive, showed a different relationship. The correlation coefficient of elite woman wrestlers' sRPE, the blood lactic acid after intensive training and urine protein is|r|>0.3,there is a low degree of correlation.Other indicators showed no significant correlation. Conclusions Training session RPE is a effective and operational noninvasive method of evaluating women's soccer training. The blood lactic acid after intensive training, urine protein, urine specific gravity and urine pH value is relatively sensitive indicator of reflecting the volume and the intensity of training.Five test indicators will be affectd by the athletes' different athletic level.

Objective It is an important content in scientific training that Scientific and effective assessment of athletes' physical function changes. By analyzing the changes of several urine biochemical indexes after the athletes' competition, the physical function and recovery of the athletes are timely understood and the basis of scientific training is provided for the coaches. Methods Urine biochemical indexes after 5 warm-up matches of 10 first athletes were measured with ten portable urine test instruments, including nitrite (NIT), acid alkalinity (pH), urine sugar (GLU), urine protein (PRO), urinary occult blood (BLD), urinary ketone body (KET), urinary bilirubin (BIL), urinary bilirubin (URO), urine specific gravity (SG), white blood cell (WBC). And statistics the positive rate. Results The urine protein and urine bilirubin were found in different degrees after the competition. The urine protein of the backfielder and the back waist was (+ + +) or (+ +). Some of the next day morning recovered normal or weak positive, the urine protein of a few athletes was (+); some of the players' Urine Bilirubin (+), the few accompanied by urinary occult blood, the positive rate was low, most of them were low. The morning urine of a number of athletes returned to normal.After the competition, the urine specific gravity of athletes was more than 1.030, and no change was observed in the morning. Other indicators did not change significantly after the match and the following morning. Conclusions Changes in urine biochemical indicators reflect the athletes' body by the competition load stimulation, in which urine protein and urine bilirubin are more sensitive to exercise load. The difference of the change degree of urine biochemical indexes in different position athletes suggests the individual differences of athletes, and also suggests the development trend of the competition, which is in line with the competitive level of the other players.

Intravenous iodinated contrast (IVIC) medium is routinely administered to dogs. Scattered information exists regarding the serum biochemical or urinary profiles associated with the administration of IVIC in dogs. The aim of the study was to describe, compare, and discuss from the perspective of previous studies the alterations in serum biochemical and urinary parameters before (T0) and within one week (T1) of the IVIC administration during routine computed tomography (CT) scan evaluation of 22 dogs. Mature dogs presenting for CT scan evaluation for preoperative oncology staging/surgical planning were included. T1 evaluation was performed within one week of IVIC administration. Statistically significant differences in serum total protein, albumin, chloride, calcium, and phosphorus concentrations, urine protein to creatinine ratio, and urine specific gravity were found between T1 and T0. At T1, the serum creatinine concentration was within reference ranges in all dogs but one. An increase in the urine protein to creatinine ratio was observed in four samples, one of which was non-proteinuric at T0. Changes in biochemistry and urine parameters between T0 and T1 were not considered clinically significant.

Background Using clinical judgment to diagnose dehydration can be highly subjective. To diagnose dehydration, it would be ideal to have an accurate, inexpensive, objective and easy-to-perform diagnostic tool. In cases of dehydration, plasma osmolality rises, causing an increase in antidiuretic hormone (ADH) secretion. The increased ADH reduces urine production and increases urine osmolality. Previous studies have show that urine osmolality correlates well to urine specific gravity. We investigated if urine specific gravity can be a reliable and objective detennination of dehydration status.Objective To assess the accuracy of using urine specific gravity as a diagnostic tool to determine dehydration status of children with diarrhea.Methods We conducted the study in the pediatric ward of Sardjito Hospital from September 2009 to December 2009. Using a refractometer we measured urine specific gravity from patients with diarrhea. This measurement was then compared to a standard of acute body weight loss, with dehydration defined as weight loss of 5% or more. The cut-off value for defining dehydration using specific gravity measurements was detennined by a receiver-operator curve (ROC).Results Out of 61 pediatric patients who were recruited in this study, 18 (30%) had dehydration as defined by a body weight loss of 5% or more. Based on the ROC, we determined the cut off  value for urine specific gravity to be 1.022. Using this value, urine specific gravity was 72% sensitive (95% CI 52 to 93), and 84% specific (95% CI 73 to 95) in determining dehydration status.Conclusion Urine specific gravity is less accurate than clinical judgment in determining dehydration status in children with diarrhea.

Abstract The most common renal symptoms of tuberous sclerosis complex (TSC) are angiomyolipomas (AMLs) and renal cysts; however, some patients with TSC also develop urolithiasis. In this study, we evaluated the incidence, risk factors and clinical courses of TSC-associated urolithiasis. We analyzed a total of 102 patients who met the diagnostic criteria for TSC, of whom 15 (14.7%) had urolithiasis. We compared urinary specific gravity, urine pH, serum calcium, intact parathyroid hormone and the use of antiepileptic agents of the urolithiasis and non-urolithiasis groups. The urine specific gravity and urine pH were higher in the urolithiasis group than in the non-urolithiasis group (P = 0.005, P = 0.042, respectively). No significant difference was found between the two groups with regard to the serum corrected calcium and intact parathyroid hormone levels. The antiepileptic drugs topiramate and zonisamide were more frequently administered to the urolithiasis group than the non-urolithiasis group (P <0.001, P = 0.039, respectively). Four patients in the urolithiasis group underwent surgery. Three patients could not receive extracorporeal shock wave lithotripsy due to the risk of bleeding from the AML, and therefore underwent transurethral lithotripsy. If urolithiasis is comorbid with TSC-associated AML, the treatment options are more limited in cases with multiple AMLs around the stone due to an increased risk of hemorrhage. Prevention and early detection of urolithiasis are beneficial to patients with TSC.
