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 To study the effect and mechanism of strengthening the spleen and tonifying the kidney on the function and apoptosis of kidney in rats.Methods The 42 male SD rats were randomly divided into quiet control group,exhausted exercise group and strengthening the spleen and tonifying the kidney group.Twenty four hours after exhaustive exercise,the concentrations of blood urea nitrogen(BUN),serum creatinine and urinary protein were determined.The apoptosis in kidneys of rats was detected by TUNEL.The structure of kidney was observed in the HE stain.Results Comparing with the exhausted exercise group,the concen- trations of BUN,serum creatinine and apoptotic index were lower significantly(P

AIM: To investigate the effects of Tangmoning (TMN) Granule on nerve conduction velocity, red blood cell sorbitol (RBC S) level in diabetic rats and probe the mechanism of prevention and treatment of diabetic peripheral neuropathy. METHODS: The model of diabetic rat was induced by strepotozotocin. The animals were randomly divided into six groups:TMN minimal dose group, TMN mild moderate dose group, TMN maximal dose group, methycobal group, model group and normal control group. All TMN groups were treated with TMN Granule through tube feeding (2.95 g/kg、5.90g/kg、11.80g/kg). Methycobal group was treated with methycobal tablets through tube feeding (0.14mg/kg). The duration of treatment was 3 weeks. The caudal nerve conduction velocity, RBC S content were investigated before and after treatment. RESULTS: It showed that TMN Granule could increase the caudal nerve conduction velocity significantly in the maximal dose group and the mild moderate dose gorup ( P

At present, antibacterial drugs are widely used in the clinical treatment of infectious diseases. It is particularly impor-tant to focus on the safety of antibacterial drugs for the application improvement in the clinical treatment. The paper reviewed and sys-tematically analyzed the relative literatures in order to explain the pathomechanism of drug-induced renal injury caused by antibacterial drugs and propose some preventive measures. The study suggested that attention should be paid to the distribution and characteristics of the adverse drug reaction of antibacterial drugs to ensure the safe and proper administration of the drugs.

Objective Hepatitis C virus patients are often accompanied by insulin resistance and diabetes.To probe the relative factors of abnormal glycometabolism in chronic HCV infections.Methods A total of 1 039 treatment-naive patients that were confirmed chronic HCV infected were enrolled in the study.The demographics,biochemical index parameters and other data about liver function and HCV viral load were got from infectious disease department of Jurong Pepole's Hospital in China.Results A total of 140 (13.5%) patients were diagnosed with some forms of abnormal glycometabolism.The body mass index (BMI) (x2 =9.231,P =0.010),waist circumference (x2 =7.984,P =0.018),systolic blood pressure (x2 =16.366,P <0.001),diastolic blood pressure (x2 =13.970,P =0.001),alanine aminotransferase(ALT) (x2 =4.809,P =0.028),HCV-RNA viral load (t =-3.818,P <0.001) were significantly different between non-diabetic HCV patients and abnormal glycometabolism patients.Multivariate logistic regression analysis showed that ALT(OR =2.986,95% CI:1.171-7.615) and HCV-RNA viral load (OR =2.061,95% CI:1.165-3.644) were found as risk factors in multivariate regression analysis for patients with chronic hepatitis C who had abnormal glucose metabolism.Conclusions Chronic hepatitis C patients with higher ALT and HCV-RNA level were more probably to suffer from abnormal glycometabolism.In order to find potentially novel risk factors of HCV with abnormal glucose metabolisn,further studies about genetic and other clinical factors need to be processed.
