Chinese Journal of Cerebrovascular Diseases 2006;3(10):433-436
Objective: To compare the therapeutic efficacy between thrombin injection and local compression on femoral pseudoaneurysms by using color Doppler flow imaging (CDFI). Methods: Thirty-eight patients with intervention-induced femoral pseudoaneurysms were randomly assigned to ultrasound-guided thrombin injection (group A, n = 19) and ultrasound-guided local compression (group B, n = 19). The volume, diameter of abnormal channel, and systolic peak velocity (SPV) of pseudoaneurysms before and after the treatment, as well as the obliterating time after the treatment were measured by CDFI. The follow-up observation was done immediately after the treatment, at day 3 and day 7. Results: The obliterating time of abnormal charmels was 4.0 ± 1.7 minutes in group A. It was significantly shorter than group B (3.6 ± 3.0 d, P=0.000). Three days later, the effective cases (19/19) in group A were significantly higher than that of group B (13/19, P=0.020) during the follow up period. Seven days later, the mean volume of hematomas in both groups was 26 ± 15 mm3, and it was significantly smaller than that before the treatment (34 ± 18 mm3, P = 0.000). The mean volume decreased 9.4 ± 8.6 mm3 in group A. There was no significant difference as compared with group B (8.6 ± 8.7 mm3, P = 0.784). One patient in group B developed deep vein thrombosis of lower limbs. Conclusion: CDFI may objectively evaluate the morphology of femoral pseudoaneurysms and the hemodynamic changes before and after the treatment. The therapeutic effect of the ultrasound-guided thrombin injection for femoral pseudoaneurysms is superior to ultrasound-guided local compression.

Aim Tostudytheantidepressanteffectand mechanism of Gross saponins of Tribulus terrestris. Methods Themodelofdepressionwasestablishedby unpredictable chronic mild stress(UCMS),then open filed test (OFT)and tail suspension test (TST)were used to evaluate the behavioral changes.LC-MS/MS method was employed to measure blood neurotransmit-ters.mRNA expressions of IDO,IL-10 and IL-1βwere detected by quantitative PCR method.Hippocampus protein expression was detected by Western blot.Re-sults Comparedwithcontrolgroup,modelgroup's total distance,number of standing and tail suspension fixed time increased significantly (P <0. 05 ),Neuro-transmitter level of 5-HT in the blood was significantly decreased(P<0. 05 ).mRNA expression of IDO and IL-1βwas increased in hippocampus.Protein expres-sion of IDO was significantly increased in hippocampus (P <0. 05 ).Compared with model group,the treat-ment group was significantly decreased in total distance,number of standing and tail suspension fixedtime(P<0. 05).Neurotransmitter level of 5-HT in the blood and mRNA expression of IL-10 in hippocampus were significantly increased after treatment (P <0. 05 ).mRNA and protein expression of IDO were ob-viously down-regulated in hippocampus (P <0. 05 ). Conclusions GrosssaponinsofTribulusterrestriscan obviously improve rat behavior and show antidepressanteffect,which can increase neurotransmitter level of 5-HT in the blood,down-regulate mRNA expression of IDO and IL-1β,and obviously increase protein expres-sion levels of IDO in hippocampus(P<0. 05 ).

Objective To establish the animal model(rabbit) of shoulder instability for providing the experimental basis of related studies.Methods shoulder joints of 6 skeletally matured New Zealand white rabbits were measured with the anatomical characteristics and joint motion range in order to determine the operative approach,the similarities of skeletal structure,surrounding muscles,joint capsule and ligaments between rabbit and human were compared.Eighteen rabbits,weighing between 2.5 and 3kg were randomized into 2 groups(experimental group 12 and control 6).In experimental group,instability model was established by means of the operation procedure as follows:the glenohumeral joint of right shoulder was exposed by cutting the subscapularis tendon,then the anteroinferior labrum and surrounding capsular ligament were excised.For control group,sham operation was performed by only curing the skin and superficial tissue,the subscapularis tendon and glenoid structures was kept intact.The specimens of 6 rabbits were harvested 6 weeks after operation.The remaining rabbits of both experimental and control groups were killed 12 weeks post the operation for specimens processing.The motion range and instability were measured in all specimens.Results The gross anatomy of shoulder ioint in rabbit is similar to human.In experimental group,the stability is showed less than control,grade 2 anterior instability was found.The motion range was restricted in all directions,such as external and internal rotation,extension and abduction compared to control group.Conclusion Rabbit is suitable to establish animal model for shoulder instability and related iniuries,the animal model which was designed by this study could provide valuable information for the research of anterior shoulder instability.

Objective ThrouGh the detection of heat shock protein 90(HSP90)Gene expression in the peripheral blood in in patients with hypertensive disorders complicatinG preGnancy( HDCP ),to understand its role in the pathophysioloGy of HDCP. Methods The expression of HSP90 was observed in Groups of normal preGnant women,Gestational hypertension patients,mild preeclampsia patients,severe preeclampsia patients by ELISA. Results The expression of HSP90 in peripheral blood of Gestational hypertension Group,mild preeclampsia Group,severe preeclampsia Group were siGnificantly hiGher than normal preGnant Group( P<0. 0l ) . Conclusion HSP90 may have close relationship with the onset and development of HDCP. It can predict HDCP by detectinG the level of HSP90 in peripheral blood.

Objectives To observe the changes of magnetic resonance imaging(MRI) during the course of treatment in hepatolen-ticular degeneration (HLD) and to evaluate its related factors.Methods Sixty - three patients with HLD received routine SE sequence MRI of brain and liver.Twenty - two patients with abnormal MRI in 42 patients and each of them had 2-4 times of serial MRI ex-aminations at interval of 1.0- 1.5 year.Results Ten patients had lesion in both brain and liver in 22 patients. Nine patients only in brain, 3 patients in liver.The major lesions disappear or decrease after rational treatments. There were only slight or no changes of MRI abnormalities in patients receiving treatments or age of patients was over 15 year old. Abnormal MRI findings shown again after stopped treatments over 2 months. In such cases, the clinical and MRI improvements were slow.The rate of clinical and MRI improvement in patients with adequate treatment were markedly higher than patients with inadequate treatment.Conclusions Liver and brain lesion will show in MRI disappear after adequate treatment;There are only slight or no change or showing again in MRI abnormalities in pa-tients with inadequate treatments compared with poor clinical improvement. MRI is beneficial to understanding therapeutic effect and prognosis of HLD.
