Objective To discuss the worthiness of real-time three-dimensional echocardiography in researching normal fetal heart ventricle growth and systolic function. Methods End-systolic volume(EDV),end-diastolic volume(ESV), struggle volume(SV) and ejection fraction(EF) of 54 normal fetal were acquired from 3-D data by Qlab software. The relation between ventricular growth with pregnant week was analysed and the difference of the volume and systolic function between left ventricle with right ventricle were compared. Results Ventricular volume of normal fetal heart (EDV,ESV,SV) were all increased with the gestational ages,there was linear relativity between them,while EF was not increased with pregnant weeks,there was no linear relativity between them. There was no statistics difference on EDV and ESV between left ventricle and right ventricle, while there was statistics difference on SV, EF between them. Conclusions The image of fetal endocarium could be derived clearly by real-time three-dimensional echocardiography, which help to get fetal heart ventricular volume and to study fetal heart growth and function.

Objective To evaluate the clinical impact of 18F-FDG PET/CT on patients with suspected cervical cancer recurrence. Methods Fifty-one cervical cancer patients, clinically suspected to have tumor recurrence during follow-up, underwent 18F-FDG PET/CT examination. 18 F-FDG PET/CT results were compared with those of conventional images, as referred to histopathology or clinical follow-up. Impacts of 18F-FDG PET/CT were evaluated based on documented changes of clinical management. Results In total, 43 patients were found to have positive lesions by 18F-FDG PET/CT, in which 40 were true recurrence,but 2 were pelvic abscess and 1 was radiation enterocolitis. Other 8 patients were found negative by 18F-FDG PET/CT and confirmed by pathology or follow-up. In patient-based analyses, the sensitivity, specificity, and accuracy of 18F-FDG PET/CT for the detection of tumor recurrence were 100% (40/40), 72. 73% (8/11),and 94.12% (48/51) respectively. In 7 patients, the clinical management was changed due to 18F-FDG PET/CT findings. Conclusion 18F-FDG PET/CT is an efficient tool for determining the recurrence of cervical cancer and instructing the clinical management.

Objective To study the effects of iodine deficiency during pregnancy on fetal iodine metabolism and thyroid function. Methods Wistar dams were randomly divided into four groups: severe iodine deficiency(SID), moderate iodine deficiency(MoID), mild iodine deficiency(MiID) and normal iodine(NI). All the dams were fed with iodine deficient food(iodine contents: 50 μg/kg) and drinking water with different doses of KI (0,54.9,163.8,381.7 μg/L) for 3 months till mating. Iodine was supplied at the dose of 1.24 μg/d(SID), 2.50 μg/d(MoID), 5.00 μg/d(MiID) and 10.00 μg/d(NI), respectively. The dams and their fetuses on gestation of 20 days were studied. Urine iodine of dams and iodine contents in fetal amniotic fluid were measured by As3+-Ce4+catalytic spectrophotometry using ammonium persulfate digestion. And blood iodine in pregnant rats and iodine contents in placental tissue were measured by As3+-Ce4+catalytic spectrophotometry in dry ash of samples in KClO3-ZnSO4-K2CO3-NaCl. Thyroid hormone levels in mother serum and in fetal amniotic fluid were detected by chemiluminascent assay, and their thyroid glands were weighted and carefully observed. Results ①Iodine content in urine and blood of pregnant rats and amniotic fluid of fetal rats reduced along with their decrease of iodine supply. Urine iodine median of rats in 4 groups(NI: 353.7 μg/L; MiID: 115.9 μg/L; MoID: 26.9 μg/L; SID: 0 μg/L) were statistically significant(χ2=32.884, P < 0.01). Blood iodine level in MoID and SID[(29.4±18.6), (11.7± 7.0)μg/L]was significantly lower than that in NI[(49.1±23.0)μg/L, P < 0.05 or < 0.01]. In iodine deficiency groups, there was a decreasing trend in iodine contents of fetal amniotic fluid[MiID: (48.3±23.1)μg/L; MoID: (29.2±14.7)μ/L; SID:(19.5±6.7)μg/L]and an increasing tendency in iodine contents of placental tissue [MiID: (0.57±0.26)μg/g, MoID: (0.53±0.34)μg/g; SID: (0.53±0.15)μg/g], but there was no statistical significance(P>0.05). ②In SID, TT4[(14.3±4.1)nmol/L]and FT4[(10.8±3.6)pmol/L]were lower than that in NI[(28.4±19.3)nmol/L, (20.2±8.0)pmol/L, P < 0.05 or < 0.01], while that in MoID[(22.1±6.1)nmol/L, (18.5±4.1)pmol/L]and MiID[(25.5±13.1)nmol/L, (18.6±8.4)pmol/L]were decreased without statistical significance(P > 0.05). And FT3/FT4 ratio(0.34±0.16), absolute[(48.4±22.7)mg]and relative weights[(144± 76)mg/kg]of thyroid gland in pregnant rats were respectively higher than that in NI[0.16±0.02, (19.5±3.1)mg, (66±10)mg/kg, P<0.01]. But that in MoID[0.19±0.04, (27.0±5.7)mg, (84±19)mg/kg]and MiID[0.17± 0.06, (25.0±8.9)mg, (78±25)mg/kg]were increased without statistical significance(P > 0.05). A visibly congestive enlargement thyroid was found in SID, while thyroid mildly enlarged in MoID and MiID. ③Compared with NI [(2.38±1.55)pmol/L,0.50±0.18], the FT4 levels [(1.07±0.87) pmol/L]in amniotic fluid were significantly decreased (P < 0.05) and the FT3/FT4 ratio (1.96±0.61) was significantly increased (P < 0.01) in SID. There were no statistical significances(P > 0.05) in other 3 groups[MiID: (2.77±0.90)pmol/L,0.46±0.15; MoID: (2.35±0.76)pmoL/L,0.61±0.21]. A visible thyroid enlargement with hyperemia was observed in SID fetus while in other 2 experiment groups their thyroids were only mildly congested. Conclusions Severe iodine deficiency during pregnancy can result in both mother and fetus overt hypothyroidism. The fetal thyroid hormone levels in mild iodine deficiency status is close to normal levels because of maternal and placental compensation. Moreover, both the dam and the fetus suffer from the negative effects in moderate iodine deficiency during pregnancy.

Objective To study effect of excessive iodine intake on sodium-iodide symporter(NIS)mRNA and protein expression of breast in lactating rats.Methods60 Wistar rats,having been weaned for one month,were randomly divided into three groups according to their body weights,I.e,①normal iodine(NI,30 rats);②ten fold high iodine(10 HI,15 rats);③one hundred fold high iodine(100 HI,15 rats).Eating food containing iodine of 300μg/L and drinking water of iodine at 5,1845,20 295μg/L,respectively.After fed for 3 months,the rats mated and had offspring,and urine and milk iodine of lactating rats were determined by As-Ce-catalytic spectrophotometric method.Their marmnary glands were sampled at lactation day 10.Then NIS mRNA expression by RT-PCR was determined and NIS protein by immunohistochemistry(SABC)was observed.Results The urine iodine of 10 HI group(3597.5μg/L)and 100HI group(25 404.3μg/L)increased obviously compared with that of NI group(344.7μg/L).The milk iodine of 10HI group(27.1×103μg/L)and 100HI group(191.0×1μg/L)was higher than that of NI group(6.0×103μg/L),but the increased fold of milk iodine was not paralleled with that of urine iodine.Difference of NIS mRNA expression was significant(F=24.19,P＜0.01)among the groups,and the NIS mRNA expression in 10HI(1.250±0.034)and 100HI(1.272±0.039)group were less than that in NI (1.532±0.044)group(P＜0.01).The breast NIS mRNA expression in lactating rats(1.532±0.044)was significantly higher than that in unlactating rats(0.879±0.018,P＜0.01).With the increasing iodine uptake,NIS protein expression decreased.Conclusions The NIS mRNA and protein in rat breasts is down-regulated by excessive iodine intake.So increasing extent of milk iodine concentration is inhibited,which is important to prevent off-spring from getting excessive iodine intake from parental generation.
