Objective To evaluate blood flow structure and quantify the variation of the flow within left ventricle,assess the impact of chronic heart failure(CHF) by vector flow mapping(VFM).Methods Twenty-seven patients with chronic heart failure and thirty controls were involved.The flow vector images on the section plane of the flow within the left ventricle were acquired by VFM.Time-flow(T-F) curve and all other peak systolic and diastolic flow curve include normal velocity profile,parallel velocity profile,vector profile,flow profile were analyzed by DSA-RS1 program.Results Ventricular ejection peak S,rapid ventricular filling peak E and atrial systole peak A were relatively lower at basal and middle segments in CHF group than normal control group.Normal velocity profile,velocity profile,flow profile at peak S and E were lower at basal and middle segments in CHF group than normal control group.Conclusions VFM technology could provide quantitative and intuitive information to demonstrate the flow structure of the ventricle and evaluate the cardiac function in patients with CHF.

Fibrous hamartoma of infancy (FHI) in the scrotum of children is a rare benign soft tissue tumor, which mostly occurs in children under 2 years old. It grows rapidly in the early stage and is easily misdiagnosed as a malignant tumor adjacent to the testis. A case of FHI in the scrotum was admitted in our hospital in recent years, a tumor resection with preservation of testicle was performed, the lesion was completely removed. Postoperative follow-up was 20 months, and there was no evidence revealing recurrence of the tumor after excision.

Objective:To compare the effect of local vibration and extracorporeal shock wave therapy (ESWT) on triceps spasticity and the walking ability of hemiplegic stroke survivors.Methods:Sixty-nine stroke survivors with hemiplegia were randomly divided into a control group, a vibration group and an ESWT group. The control group received 60 minutes of conventional Bobath rehabilitation treatment and motor relearning from Monday to Saturday for 4 weeks. For the vibration and ESWT groups, 10 minutes of that traditional therapy were replaced by either local vibration or extracorporeal shock wave treatment every Tuesday, Wednesday and Saturday. Before and after the treatment, the three groups were evaluated using the Comprehensive Spasticity Scale (CSS) and in terms of passive joint range of motion (PROM), ankle plantar flexion angle, 10m maximum walking speed, stride frequency, and stride length.Results:After the intervention the average CSS, PROM, and ankle plantar flexion angle were significantly better for all three groups than before the treatment. At that point the ESWT group′s averages were significantly better than those of the vibration group, and the vibration group′s averages were significantly superior to those of the control group. Walking speed, stride frequency and stride length had also improved significantly in all three groups, with those in the vibration and ESWT groups significantly outperforming the control group. There was no significant difference between the vibration and ESWT groups in terms of walking ability.Conclusions:Both local vibration and extracorporeal shock wave therapy improve triceps spasticity and the walking ability of hemiplegic stroke survivors. Shock waves are more effective for improving spasticity, but there is no significant difference between the therapies in terms of improving walking ability.
