Eight parameters about iron nutrition were observed longitudinally in eighty pregnant women from the first trimester to delivery. Their nutrients intake were recorded at the same time. It was noted that serum iron store (ferritin) decreased markedly in the course of pregnancy and the incidence of iron deficiency increased. Total iron intake was closely related to the variation of these parameters, the degree of iron deficiency in pregnant women and the content of cord ferritin. Iron in maternal serum is correlated to ferritin in the cord blood. It suggested that natural food abundant in iron, or food fortified with iron should be taken in early pregnancy to prevent iron deficiency of mothers.

Objective To investigate the radiation-induced esophageal toxicities in Ⅲ stage non-small cell lung cancer (NSCLC) treated by three-dimensional conformal radiotherapy (3DCRT) combined with concurrent chemotherapy, and to find the relevant predictive factors. Methods From September 2006 to October 2007, 37 patients with stage Ⅲ NSCLC were treated by 3 DCRT (60 Gy in 30-34 fractions) con-currently with navelbine and cisplatin (NP). Chemotherapy was given in the first and fifth week. Univariate and multivariate analyses and receiver operating characteristic curves (ROC) were used to assess the associ-ation of radiation-induced esophagitis and correlated factors. Results Of all the patients, 91.89% (34/37) developed radiation-induced esophagitis, including grade 1 in 11 patients, grade 2 in 9, grade 3 in 14 and grade 4 in none. According to Spearman correlative analysis, the correlative factors included mean esophagus dose (MED), the LETT_(40)、LETT_(45)、LETT_(50)、LETT_(55)、LETT_60)of esophagus.All the 11 factors had good correlation with esophagitis in univariate analysis, while only V_55 was independ-ently associated with esophagitis in multivariate analysis. The ROC analysis indicated that the cut-off point of the curve was 30% with the area under ROC curve of 0.906, (P=0.000). Grade 2 or 3 radiation esophagi-tis occurred in all the patients with esophageal V_55 > 30%, while only in 36% ( 8/22 ) of those with V_55<30%. Conclusions 3DCRT combined with concurrent chemotherapy in patients with stage Ⅲ NSCLC could develop severe esophagitis. Dosimetric parameters (MED, LETT_(40),LETT_(45),LETT_(50),LETT_(55),LETT_(60),V_(40),V_(45),V_50,V_55,V_(60))are related with esophagitis,V_55 with V_55 > 30% being the most valuable predictor.

Objective To evaluate the clinical value of 131 Ⅰ SPECT/CT in the differentiation of indeterminate 131Ⅰ uptake on planer whole body scan (WBS) for patients with DTC after 131Ⅰ treatment. Methods Fifty-six DTC patients ( male: 19, female: 37, mean age: 45 ± 15 years, ranging from 20 to 85 years) underwent 131Ⅰ treatment. 131Ⅰ WBS was performed five days after 131 Ⅰ treatment, followed by regional 131Ⅰ SPECT/CT for the indeterminate foci with abnormal uptake on 131Ⅰ WBS. The diagnostic difference of the two imaging modalities was compared by x2 test. Results There were 288 foci with abnormal uptake on 131 Ⅰ WBS, including 108 indeterminate foci (37.5%). Subsequent 131Ⅰ SPECT/CT identified 27 foci as DTC metastases (25.0%) and 71 foci as non-metastases such as benign lesions at nose, oral cavity, salivary gland, maxillary cyst, thyroid remnant, thymus, gallbladder, gastrointestinal tract, and uterus, or non-specific uptake of body contaminations (65.7%). However, the remaining 10 foci (9.3%) remained indeterminate on 131 Ⅰ SPECT/CT imaging. The diagnostic accuracy of 131 Ⅰ SPECT/CT was significantly higher than that of 131Ⅰ WBS (x2 = 102.35, P<0. 01). Conclusion 131Ⅰ SPECT/CT could significantly improve the diagnostic accuracy for the differentiation of indeterminate foci with abnormal uptake on 131Ⅰ WBS.

Objective To investigate the G protein-coupled receptor kinase 2 (GRK 2) level in peripheral blood lymphocytes with cardiac func-tion in elderly patients with acute myocardial infarction. Methods This study enrolled 40 patients with acute ST-segment elevation myo-cardial infarction (STEMI) and 40 patients with unstable angina. All patients were 65 years or older. Cardiac function was evaluated by echocardiography, and the GRK 2 level in peripheral blood lymphocytes was measured. Patients with STEMI were followed up for 2 years. Results The GRK 2 level in peripheral blood lymphocytes was significantly higher in patients with STEMI than in patients with unstable angina, and was negatively correlated with left ventricular ejection fraction, cardiac output, stroke volume, and left ventricular fractional shortening. The GRK 2 level was significantly elevated in some patients with acute STEMI and poor cardiac function. Conclusions In-creased GRK 2 level in patients with acute STEMI may contribute to poor myocardial systolic function and myocardial remodeling. Meas-urement of the GRK 2 level in peripheral blood lymphocytes may assist in the evaluation of cardiac function and myocardial remodeling in elderly patients with acute STEMI.

Objective To investigate the feasibility of Wilms’tumor gene 1 (WT1)-specific CD8+T cells from periph?eral blood for the treatment of breast cancer by detecting the killing activity of WT1 specific CD8+T cells on breast cancer cells. Methods Flow cytometry was used to detect WT1-specific CD8+T cells in the peripheral blood of 20 samples from HLA-A2 seropositive healthy donors, which were isolated by WT1/MHC streptamer magnetic beads and cultured. The func?tion of WT1-specific CD8+ T cells were analysis by cytotoxicity assay. Results Twelve of 20 healthy donors had naive WT1-specific CD8+T-cell frequencies of>0.5%, and 4 of 20 even>1.0%of all CD8+T cells. After positive selection by magnetic cell separation, a purity of up to 80%can be achieved. WT1 specific CD8+T cells can specifically kill breast can?cer cell line with WT1 polypeptide. Conclusion WT1 specific CD8+T cells can be detected in peripheral blood of healthy volunteers. WT1 specific CD8+T cells have killing effect on breast cancer cells, suggesting the feasibility of adoptive immu?notherapy for breast cancer.
