Objective To investigate the clinical value of contrast-enhanced ultrasound(CEUS) in the diagnosis of postnatal placenta increta. Methods Twenty-six patients with postnatal placenta increta were examined by gray-scale and color Doppler ultrasound and CEUS. Then microvascular perfusion and enhanced features of lesions, myometrium and serous layer were observed. Arriving time (AT), time to peak intensity (TTP) and the lasting time of enhancement (LTE) were recorded. AT,TTP and LTE of enhanced lesions were compared with those of normal myometrium. Results Serous layer, lesions and adjcent myometrium,normal myometrium enhanced in turn. There was no obvious boundary between the lesions enhanced and adjcent myometrium. AT and TTP of the lesions enhanced were both less than those of normal myometrium ( P ＜0. 05). LTE of the part of lesions enhanced was more than that of normal myometrium ( P ＜0.05).Part of lesions never enhanced during the whole process. The serous layer of uterine was smooth and uninterrupted in 24 patients. These 24 patients all recovered after conservative treatment. The local serous layer adjcent lesions was not smooth, but no contrast agent leakage occurred in another 2 patients, and uterine lobectomy were performed in emergency because of massive hemorrhage during conservative treatment. Conclusions Microvascular perfusion and enhanced features of lesions,myometrium and serous layer could be showed clearly through CEUS.

Objective To observe the role of abatacept in the treatment of diabetic nephropathy in rats. Methods Type 2 diabetic nephropathy rat model was established, and was randomly divided into abatacept group and non-intervention group, 15 each. 15 normal rats were served as control group ( NC) . The abatacept group was given abatacept for 8 weeks. The control group was set at the same time period. Then the blood biochemical indexes, blood flow parameters of renal main artery, elasticity of renal parenchymal, HE staining of renal parenchymal and ultrastructure of podocytes were all evaluated. The expression of CD31, CD34, podocin, nephrin, and B7-1 in renal parenchyma were detected. Results Compared to the NC group, the fasting blood glucose, creatinine clearance rate, urine albumin excretion rate, and kidney hypertrophy index in the non-intervention and abatacept groups were significantly increased (P<0. 05);creatinine clearance rate, urine albumin excretion rate, and kidney hypertrophy index in the abatacept group were significantly lower compared to the non-intervention group (P<0. 05). There were significant differences in peak systolic velocity, end diastolic velocity, and mean velocity among these 3 groups, and these differences were ranked as non-intervention groupabatacept>control groups (P<0. 05). There were significant differences in the stiffness of kidneys among these three groups, with the differences ranked as non-intervention>abatacept>control groups (P<0. 05). HE staining and transmission electron microscope observation showed that there were obvious changes in the renal parenchyma of rats in the non-intervention group and the abatacept group, and the changes of kidney in the non-intervention group were worse than those in the abatacept group. CD31 and CD34 expression in kidney parenchyma of rats in the abatacept group and non-intervention group were higher than those in the control group, the abatacept group and non-intervention group>the control group (P<0. 05), while no significant differences between the abatacept group and non-intervention group in CD31 and CD34 expression (P>0. 05). There were significant differences in podocin and nephrin expression in kidney parenchyma of rats among these three groups, and these differences were ranked as the control>abatacept>non-intervention groups (P<0. 05). There were significant differences in B7-1 expression in kidney parenchyma of rats among these three groups, and these differences were ranked as the control

Objective To assess the clinical value of three-dimensional hysterosalpingo-contrast sonography (3D Hy-CoSy)in patients with tubal infertility. Methods A total of 274 patients with infertility(totally 539 the fallopian tubes)from September 2011 to March 2013 in our hospital,all patients were choose 3~7 days after menstruation clean,Transvaginal three-dimensional ultrasound imaging by injecting SonoVue through the uterine tube,with dynamic obser-vation of fallopian tube in imaging mode,by adopting of transvaginal three-dimensional ultrasound imaging reconstruc-tion technology evaluate tubal patency. The result of transvaginal three-dimension ultrasound imaging among 67 cases were compared with laparoscopic Meilan hydrotubation or X-ray hysterosalpingography (HSG). Results Among 539 oviducts, 230 oviducts were diagnosed patency by HyCoSy,224 oviducts were incompletehy obstructed, and 85 oviducts were completely obstructed among which 7 were hydrosalpinx; 3 out of 274 cases were contrast medium reflux into myometrium and venous plexus nearby; The sensitivity of 3D HyCoSy was 86.67%,which compared with the re-sults of HSG and laparoscopy,specificity was 100%,positive predictive value was 96.30%, negative predictive value was 98.25%. Conclusion 3D-HyCoSy in the diagnosis of fallopian tube patency is simple, safety and effective,fully and accurately displaying the shape of uterine tube . This technique is hopeful to become an effective method to diag-nose patients with tubal infertility.
