ObjectiveTo explore the imaging features of fetal tuberous sclerosis complex by ultrasonography and magnetic resonance imaging.MethodsRetrospective analysis on the imaging characteristics of the 10 cases of fetuses confirmed as tuberous sclerosis complex who were examined in Hubei Maternal and Child Healthcare Hospital in July 2013 to December 2014 by ultrasonography and MRI, which was compared with the pathological data of specimens and follow-up after birth.ResultsEighteen cases were diagnosed as fetal cardiac rhabdomyoma by ultrasonography among all of the 996 fetuses, in which lesions were located on the ventricular wall near septum or elsewhere in the heart cavity on ultrasonography. Fetal cardiac rhabdomyoma was characterized by circular, homogeneous high echo (singleton in 4 cases, multiple in 14 cases). Among them no subependymal nodule was found by ultrasonographic. Ten cases of subependymal nodule were found by magnetic resonance imaging, which were diagnosed as tuberous sclerosis complex with cardiac rhabdomyomas, including 3 cases of brain subcortical tubers. The subependymal nodules under the lateral ventricle wall showed characteristic low signal nodules on T2WI, protruding from the ependymal surface. Of 18 cases, only 4 cases of fetal cardiac rhabdomyoma were found by MRI. Nine cases of ifnally had termination of pregnancy. Two cases were conifrmed as cardiac rhabdomyoma with intracranial nodules after pathological examination, and 1 case was conifrmed as tuberous sclerosis complex after birth. ConclusionsPrenatal ultrasonography can diagnose fetal cardiac rhabdomyoma successfully, and MRI can diagnose the fetal brain nodules sensitively. Once ultrasonography finds cardiac rhabdomyoma, it may be promising to diagnose fetal tuberous sclerosis complex by ultrasonography combined with MRI.

Objective To determine the expression of CD4+ CD25+ FOXP3+ regulatory T cells(Treg cells) in peripheral blood of patients with hepatocellular carcinoma (HCC) and investigate the clinical significance of Treg cells determination in clinical practice. Methods Flow cytometry was employed to measure the levels of CD4+ CD25+ T cells and CD4+ CD25+ FOXP3+ T cells in peripheral blood of 18 HCC patients, 26 hospitalized patients without HCC (clinical control) as well as 24 healthy persons (healthy control). Results The percentage of CD4+ CD25+ T cells in total CD4+T cells isolated from the HCC patients(4.25% ± 3.98 % ) was elevated significantly compared to that in the clinical control group (1.34% ± 1.14%) or healthy control group (1.29% ±0.95%) (both P＜0.01). There was no difference in the percentage between the clinical control group and the healthy control group (P＞0.05). Meanwhile, the ratio between CD4+ CD25+ FOXP3+ T cells and CD4+ T cells in HCC patients (2.94%0.91%) also increased significantly compared to that in the clinical control group (0.76% ± 0.34%) or healthy control group (0.81% ± 0.29%) ( both P＜0. 001), which showed a more obvious increasing tendency than the ratio of CD4+ CD25+ T cells and CD4+ T cells. No difference in percentage of CD4+ CD25+ FOXP3+ T cells in CD4+ T cells was found between the clinical control group and the healthy control group (P＞0.05). Conclusion As the more accurate regulatory T cells, CD4+ CD25+ FOXP3+ T cells are able to detect the increase of population in HCC patients. Therefore, it is important to determine the levels of CD4+ CD25+FOXP3+ T cells in HCC patients for prevention and treatment of malignancy.
