Objective To study the diagnostic value of transperineum color Doppler ultrasonography (TPCDU) and transabdominal color Doppler ultrasonography (TACDU) in pelvic varicosis (PV). Methods Thirty-eight patients with PV were detected by using TACDU and TPCDU separately, and the diagnostic value between the two ways was compared. Operational results was used as standard, and the degree of lesion in patients with PV was evaluated based on the results of surgery. Results The rate of diagnostic accuracy was high in both methods (TACDU 92% and TACDU 79%, separately). However, the rate of diagnostic accuracy and the site detectable were significantly higher by TPCDU than by TACDU (P

Objective To evaluate the value of color Doppler flow imaging(CDFI) in diagnosis of choroidal melanoma.Methods A comparative analysis was carried retrospectively on sonograms,pathological and clinical data of 13 choroidal melanoma cases,confirmed by pathology and operation.Results The pre-operative diagnosing rate of choroidal malignant melanoma by CDFI in the study was 100%.The sonogram features were divided into three types: hemispherical type,mushroom type and diffusive type.Conclusions Characters of blood flow signal of intraocular occupying lesions were valuable to distinguish choroidal malignant melanoma from other diseases.

Objective To study the relationship between ultrasonography of arteria dorsalis pedis and Hemorheology in patient with diabetic foot.Methods According to with or without frank anabrosis,51 patients were devided into two sub-groups:anabrosis group (23 patients) and no-anabrosis group (28 patients).The correlativity was analysed between the parameters of ultrasonography in arteria dorsalis pedis and hemorheological indices on patients with diabetic foot.Results When compared to patients without ulcers,vascular inner diameter (D),peak systolic velocity (PSV),resistent index (RI) and pulsatility index (PI) on patients with frank anabrosis were decreased significantly,but whole blood viscosity at high shear rate (BVH),whole blood viscosity at low shear rate (BVL),plasma viscosity (PV),fibrinogen (Fib) were increased.Multiple regression analyses indicated that the relationship between BVH,BVL and D was presence,partial regression coefficient (r) was -0.004 and -0.009 ; the relationship between PSV and BVH,PV was intimate,r was -0.957 and -25.655 ; the relationship between RI and BVH,PI and BVH,PV,Fib were relatively intimate,r was -0.009 , -0.141 , -2.666 , -0.383 ,respectively.Conclusions The changes of hemorheology can aggravate the abnormality of hemodynamics and the degree of vascular lesion in small vessels of lower limb,so it is one of influencing factor leading to lower limb arterial ischaemia and diabetic foot deterioration.

ObjectiveTo assess the related risk factors of myocardial lesion in diabetes patients and the value of ultrasonic integrated backscatter in the assessment. MethodsThirty diabetes patients, which were divided into two groups based on their blood pressure, and twenty controls undergone conventional echocardiography and ultrasonic integrated backscatter analysis. Data reflecting the glycemic control (FA) were also collected and analyzed.ResultsThere was a significant difference in IB%, CVIB and THIB% between diabetes patients and controls. Greater THIB% was shown in diabetes patients with hypertension compared to that of diabetes patients without hypertension. THIB% correlated with FA significantly. Conclusions Hypertension and the poor glycemic control are two risk factors to myocardial lesion in diabetes patients. The ultrasonic integrated backscatter is useful in assessing the effects of the two factors to the myocardial lesion in diabetes patients.

AIM: To elucidate the effect of calcitonin gene-related peptide (CCRP) in the therapy of atherosclerosis.METHODS:Effect of CGRP on cell cycle kinetics of cultured vascular smooth muscle cells(HA-VSMC) was investigated by flow cytometry. The expression of cyclins D 1 and E required for initiation of S phase were also studied by immunochemistry method. RESULT: CGRP was shown to arrest VSMC in the G 0/G 1 phase of cell cycle and reduced expression of cyclins D 1 and E. CONCLUSION:CGRP inhibits proliferation of HA-VSMC by arresting cells in G 1 phase via limiting accumulation of cyclin D 1 and E. It might play a role in the therapy of atherosclerosis.

Objective To identify the Banna viruses isolated in northwestern part of Yunnan prov-ince in order to make the difference clear between the isolates and other Banna viruses isolated in other parts of Yunnan. Methods Three isolates of Banna vires isolated in 2005 and 2006 were identified by morpholo-gy, RNA-PAGE profile and molecular biologic method. Nueleotide and amino acid sequences of segment 12 of the 3 isolates were sequenced and analyzed. Results Three Banna viruses were isolated from mosquitoes collected in northwestern part of Yunnan during 2005 and 2006. Electron microscopy study showed that they are spherical with a diameter of 70 nm, no envelope but two layers of eapsid. It was found that the genome of the 3 isolates composes of 12 segments presenting band profile of 6-6 in RNA-PAGE. Nueleotide acid se-quence analysis about segment 12 showed that the identity was 99% between the 3 new isolates, 98% and 90% between the 3 isolates and the strains isolated in other parts of Yunnan, China and Indonesia, respec-tively. Phylogenetie analysis based on segment 12 gene showed that 3 new isolates clnstered in the same branch with the viruses isolated in other parts of Yunnan. The same difference of amino acids was found between Banna viruses isolated in China and Indonesia strains in the analysis of segment 12. Conclusion Banna virus strains were firstly isolated from mosquitoes collected in northwestern part of Yunnan province. Nueleotide acid sequence analysis of the 3 new isolates showed higher identity with strains isolated in other parts of Yunnan.
