Objective To investigate the echocardiographic features and clinical significance of prenatal diagnosis of total anomalous pulmonary venous connection (TAPVC). Methods Fetal echocardiographic images of 13 fetuses with TAPVC conifrmed by pathology or postnatal echocardiography were reviewed. Echocardiographic features and clinical signiifcance of prenatal diagnosis of TAPVC were summarized. Results Twelve fetuses with TAPVC were diagnosed prenatally by fetal echocardiography, including seven cases of supracardiac type, three cases of infracardiac type and two cases of intracardiac type. The common echocardiographic characteristics of 12 fetuses with TAPVC included slightly size discrepancy of left heart and right heart, large foramen ovale with increased shunting at the atrial level, increased distance between left atrium (LA) and descending aorta, absent insertions of pulmonary veins in the LA, presence of pulmonary venous conlfuence on the top of LA and dilatation of vessels where pulmonary venous conlfuence drained. One case was missed prenatally and intracardiac type TAPVC was diagnosed by postnatal echocardiography. Among the 13 cases, three were isolated and the other ten were all in association with other abnormalities. Conclusions There are fetal echocardiographic characteristics of TAPVC. Fetal echocardiography plays an important role in prenatal diagnosis of TAPVC.

OBJECTIVETo observe the clinical effect of Huikangling Tablet (HT, extracted from Scabrous Patrinia root) on peripheral blood micrometastasis of differentiated thyroid carcinoma (DTC) patients.
METHODSTotally 87 DTC patients with positive micrometastasis were randomly assigned to the treatment group (45 cases) and the control group (42 cases). DTC endocrine inhibition treatment standards were executed in all patients. They all took levothyroxine sodium (50 microg/tablet, from low dose, 25 microg each time, once per day, 0.5 h before breakfast), and its dosage was gradually added one week later. The dosage was adjusted according to tested results of TSH combined recurrence risk stratification and endocrine suppression induced adverse reactions risk stratification. Patients in the treatment group took HT (0.4 g per tablet, 3 tablets each time, three times per day for a total of 12 weeks) combined TSH suppression therapy, while those in the control group only received TSH suppression therapy. Peripheral micrometastatic cytokeratin 19 (CK19) and polymorphic epithelial mucin1 (MUC1) were detected by FCM at week 4 and 12. Meanwhile, distant metastasis and adverse reactions were observed.
RESULTSAfter 4-week treatment positive micrometastasis was shown in 18 cases (40%) of the treatment group and 29 cases (69%) in the control group with statistical difference (chi2 = 5.68, P < 0.05). After 12-week treatment positive micrometastasis was shown in 7 cases (15.6%) of the treatment group and 17 cases (44.7%) in the control group with statistical difference (chi2 = 8.49, P < 0.01). Pulmonary metastasis occurred in 2 cases and bone metastasis in 1 case of the control group at follow-ups. Cervical lymph node metastasis without accompanied recurrence of thyroid cancer occurred in one case of the treatment group. No obvious liver or renal abnormalities occurred.
CONCLUSIONHT inhibited peripheral blood micrometastasis of DTC patients and its mechanism needed to be further studied.
