Objective To explore the value of MRI combined with transvaginal ultrasonography in the diagnosis of cesarean scar pregnancy.Methods Appearances of MRI and transvaginal ultrasonography of cesarean scar pregnancy confirmed by surgery and pa-thology in 30 patients were retrospectively reviewed,and the diagnostic value of MRI and transvaginal ultrasonography in the cesare-an scar pregnancy were compared and analyzed.Results MRI and transvaginal ultrasonography clearly demonstrated the gestational sac at cesarean scar of lower uterine in 30 patients including cystic sacs in 22 and solid ones in 8.Both MRI and transvaginal ultra-sonography showed 5 gestational sacs were located at the myometrium and 1 7 extended to uterine cavity.Intrauterine hemorrhage was detected by MRI in 12 patients and by transvaginal ultrasonography in 8.Transvaginal ultrasonography found 14 yolk sacs and 12 embryonic buds with embryonic heartbeat in 8.However,MRI cannot differentiate yolk sac from embryonic bud,and not judge the embryonic heartbeat.Preoperatively,28 patients were diagnosed as caesarean scar pregnancy and other 2 were as trophoblastic tumor by MRI with an accuracy rate of 93%;meanwhile,27 were diagnosed as caesarean scar pregnancy and other 3 as trophoblastic tumor by transvaginal ultrasonography with an accuracy rate of 90% .There was no statistical difference in diagnostic efficiency be-tween MRI and transvaginal ultrasonography (P >0.05).Conclusion The diagnoses of cesarean scar pregnancy by both MRI and transvaginal ultrasonography is highly consistent with pathological results.The combination of two imaging modalities may maxi-mize their advantages and provide more detailed information for rapid diagnosis of cesarean scar pregnancy.

Objective To investigate the distribution of the obstructive lesion of hepatic vein and inferior cava vein in patients with Budd-Chiari syndrome in Henan Province of China.Methods A total of 231 cases with Budd-Chiari syndrome were diagnosed by combination of three imaging techniques which either included colour Dopple ultrasound,multislice CT and vasography or colour Dopple ultrasound,MR angiography and vasography.All the hepatic veins,accessory hepatic veins and inferior vena cavae were imaged and their obstructions were detected and analysed.Results Out of the 231 patients there were 5 cases(2.2%)with simple obstruction of inferior vena cava with normal hepatic branches.Thirty-three cases(14.3%)had simple hepatic vein obstruction with normal inferior vena cava.The remaining 193(83.5%)cases had vein obstruction both in hepatic vein and inferior vena cava.Conclusion The most frequent form of Budd-Chiari symdrome in Henan province of China is the complex obstruction of inferior vena cava and heptic vein,and simple obstruction of inferior vena cava occurs the least.

Angelica dahurica is diaphoretic, commonly used in the treatment of cold, wet, and itchy rubella nasosinusitis. Studies have shown that the effective components of Angelica dahurica can be used in the treatment of malignant tumors. This paper summarizes the related literature home and abroad recently, and regards the effective components of Angelica dahurica as a major role in treatment of tumor by inhibiting tumor cell proliferation, promoting apoptosis, inhibiting tumor metastasis, inhibiting platelet aggregation, enhancing immunity, and anti-tumor drug resistance. Meanwhile, the paper finds the shortcomings of the present researches, and hopes to provide reference for the future experiment and clinical research.
