Ultrasonic diagnosis of uterine arteriovenous fistula / 中国介入影像与治疗学

ObjectiveTo investigate the value of ultrasound in diagnosis and differential diagnosis of uterine arteriovenous fistula (UAF).MethodsUltrasound results of 12 patients with UAF were analyzed retrospectively,and were compared with uterine artery angiography.ResultsUAF showed uneven echo signals of uterine muscle wall near endometrium or cesarean section incision and irregular echo-free zone on ultrasonographies,the typical case of which displayed “honeycomblike” change.Color Doppler ultrasound showed rich blood flow in local area and lake-like or multicolored mosaic change.Spectral Doppler waveform shape was characterized as high-speed low resistance.The ultrasonographic results of UAF were consistent with those of uterine artery angiography.ConclusionUltrasonography combined with uterine artery angiography contributes to the diagnosis of UAF.

Effects of Treadmill Training for One Week on α-actin Gene Expression of Rat Skeletal Muscle / 中国运动医学杂志

It was well known that the damage of skeletal muscle occurred and exercise performance declined after one prolonged eccentric exercise.But there were few studies on the adaptation to the continuous eccentric exercise in skeletal muscle.The purpose of this study was to investigate the effects of downhill running once(group B) and for one week(group C ) on α-actin gene expression of rat gastrocnemius muscle.Serum CK and LDH were determined, too.The results showed that the training had obvious effects on α-actin gene expression of rat gastrocnemius muscle in group B and C.In group B, serum CK and LDH recovered obviously 7 days after training, but not to the normal value.In group C, it recovered to the normal.These results suggest that the recovery of the damage after first training had been accelerated by the continuous eccentric exercise, the subjects gradually adapted to exercise.

Effects of Exercise on the Action Scores and Plasma Adrenocorticotropin and Corticosterone in Rats under Psychological Stress / 中国运动医学杂志

group C,CORT value in group I was significant higher than in the other two.In group I+S,the CORT and ACTH concentrations were lower than that in group I,but higher than that in group C and C+S.Conclusion Chronic psychological stress could induce stress-related hormone excretion and action alteration.Exercise to some degree could mitigate the psychological stress reactions.
