To explore the value of two dimensional ultrasonography used in gunshot wound, features of gunshot wound in pig thigh were studied by high frequency ultrasound and compared with pathologic examination. The primary wound tract showed remarkable features in ultrasonography with a cured anomalous pipelike image, which changed with time. Tissues around the wound tract also revealed some sonographic characteristics. The results indicate that two dimensional ultrasound can clearly manifest not only the shape and distribution of the wound tract, but also the relation between the tract and its adjacent tissues. Therefore, the method is of important value in treatment of gunshot wound.

0.4?g was defined as the cutoff,then these patients were divided into two groups,the elevated group and the normal group,and were followed up for a month to compared with the rate of cardiac events.Results Among the 62 cases,there were 8 cardiac events in the evelated group of 24 patients.2 cardiac events in the normal group of 38 patients.There was a significant difference between the two groups(P

Objective To explore the value of two dimensional and color Doppler flow imaging(2D CDFI)for the diagnosis and differentiation of the carotid body tumor.Methods Retrospective analysis was made on 12 patients with carotid body tumor examined by 2D CDFI,and differentiations were conducted between several similar diseases.All the cases were confirmed by surgical pathology.Results The carotid body tumor in 2D CDFI was shown as follows: Low echoic substantial masses were found in the carotid branch with clearly boundary,and or partly outline.Most in small size were located at the branch of common carotid artery,so the interval between external and internal carotid arteries was enlarged.The masses in big size always grew around common cartid artery internal carotid artery and external carotid artery.More color flow signals were detected in the masses,and most were artery flow.The relationship between the mass and the carotid was shown clearly by 2D CDFI.Conclusions 2D CDFI is a valuable and practical method in diagnosis of carotid body tumors.

BACKGROUND: Comparing with diabetic nephropathy and diabetic retinopathy, diabetic cardiomyopathy is put forward exceeded later and the research about it was not enough. It is difficult to detect diabetic cardiomyopathy in the earlier period so that it has usually been neglected.OBJECTIVE: To evaluate features of dysfunction of left ventricle in early diabetic cardiomyopathy by Doppler tissue imaging.DESIGN: Completely randomized and controlled experiment.SETTING: Ultrasound Department of General Hospital of Chengdu Military Area Command of Chinese PLA.MATERIALS: The experiment was carried out at Ultrasound Department of General Hospital of Chengdu Military Area Command of Chinese PLA from March to June 2002. Totally 56 New Zealand rabbits of either gender were selected.METHODS: ① Ten New Zealand rabbits was pulled out randomly from 56 as control group. The rest of 46 New Zealand rabbits were replicated diabetes mellitus by Streptozotocin (STZ), rabbits were absolute diet 18 hours and injected intravenously to ear marginal vein with 65 mg/kg of STZ. Then these rabbits were randomly divided into 4 groups as 2, 4, 6, 8th experimental group, with 10 rabbits in each group. ② Digit ultrasonic cardiogram equipment was used to examined interventricular motion of mitral annulus at 2nd,4th, 6th and 8th week in model groups and comparison group. The parameters such as systolic peak velocity (Sa), preejection period (PEP), local ejection time (ET), systolic mean velocity (Vm) of four various portions in mitral annulus and diastole early period velocity (Ea), diastole later period velocity (Aa), Ea/Aa were determined. ③ SPSS 11.0 was used for statistical analysis,one-factor analysis was adopted to compare difference of groups.MAIN OUTCOME MEASURES: The motion of lateral wall and posterior interventricular septum at mitral annulus were estimated by PW-DTI.RESULTS: Among 56 rabbits, 50 entered the final analysis and other 6 were lost because of failure modeling. Diastole dysfunction of left ventricle was discovered in STZ-inducod diabetic rabbits detected by tissue Doppler imaging at the 4th week. It showed that not only the tite of early period of diastole peak velocity (Ea) in mitral ring lateral wall and post-interval of left ventricle was reduced, but also the tite of Ea/Aa was reduced notably (P ＜ 0.05). Systolic dysfunction of left ventricle was discovered in STZ-in-duced diabetic rabbits detected by tissue Doppler imaging at the 6th week.It showed that local contraction peak velocity (Sa) of lateral wall and postseptum of mitral ring was decreased strikingly (P ＜ 0.05). Mean systole velocity of four various parts of mitral ring (Vm) was reduced at the 6th week (P ＜ 0.05). Pre-ejection period time (PEP) at post-septum and ejection time (ET) was elongated at lateral wall at the 8th week (P ＜ 0.05).CONCLUSION: ① Diastolic dysfunction of left ventricle is characterized by decrease of early period of diastole peak velocity and the tite of Ea/Aa.② Systolic dysfunction of diabetic cardiomyopathy is characterized by decrease of local contraction peak velocity and elongation of pre-ejection period time and ejection time.

OBJECTIVETo assess the role of orthotopic liver transplantation (OLT) in the treatment of end-stage liver diseases and to discuss the experience of the operation.

METHODSRetrospective analysis of clinical data of 71 cases of liver transplantation was performed in our hospital from April 1993 to August 2001.

RESULTSOne year survival rate of recipients with benign hepatic disease was over 75%. The survival time and life quality of malignant recipients were also improved. Lamivudine monotherapy during the operation period could reduce HBV reinfection rate. The practice of OLT without veno-venous bypass (VVB) was associated with a shorter operating time, less hemorrhape, and thus less blood transfusion during the operation compared with standard technique of OLT with routine use of VVB. The occurrence rate of biliary complications was 5.98% and vascular complication 8.96%.

CONCLUSIONSOLT should become a routine therapeutic choice for end-stage liver diseases. Lamivudine is helpful to reduce HBV reinfection after OLT in HBV-related liver diseases. OLT without VVB is safe and can be performed in the majority of adult patients. The early diagnosis and timely application of interventional radiological technique are important for the treatment of biliary and vascular complications.
