Lung metastases are more common in metastatic disease in differentiated thyroid carcinoma (DTC). Because of its insidious onset and slow development, clinical diagnosis is relatively difficult. Some possible diagnostic methods for detecting the lung metastasis of DTC including serological examination, radionuclide imaging and other medical imaging patterns are discussed in this paper. The progress and the current situation about investigation of those modalities which are in the early diagnosis, recurrent and clinical evaluation for the lung metastasis of DTC are briefly reviewed. Therefore, it is expected to promote DTC with lung metastasis to a higher diagnostic level.

Objective To analyze the clinical characteristics of autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and AIH/PSC or/PBC overlap syndrome in order to further understand the autoimmune liver diseases (AILD). Methods One hundred and nine patients with AILDs confirmed pathologically were collected between Jan. 2004 and June 2006. Of 109 patients, AIH was found in 27 eases, PBC in 67 cases, PSC in 4 eases, AIH-PSC overlap syndrome in 1 case and AIH-PBC overlap syndrome in 10 cases. The clinical and laboratory data of all patients were assessed retrospectively. Results The AILD was predominantly found in middle-aged women (73.3% ,80/109), and the main clinical manifestations were jaundice, malaise, anorexia and pruritus. The age distribution of patients with AIH showed a single peak at 50 years. Elevated serum gamma globulin and IgG were found in patients with AIH, of whom 62.9% (17/27) were positive for anti-nuclear antibody (ANA) and 3 were positive for liver-kidney microsomes type 1 antibody. The main histological changes in severe AIH cases included interface hepatitis (77.7 %) and bridging necrosis. Most of the PBC patients were presented with elevated serum alkaline phosphatase, glutamyl transpeptidase and IgM. Fifty patients (74.6%) were positive for anti-mitochondrial antibody (AMA) and AMA-M2. The pathological examination showed that 28. 3% of the cases were in Ⅰ or Ⅱ stage and 71.7% in Ⅲ or Ⅳ stage in patients with PBC who received liver biopsy. The pathologic change of reduction or even disappearing of bile ducts was found in 62. 6% patients with PBC. The clinical and pathological manifestations in patients with AIH-PBC overlap syndrome had both characteristics of PBC and AIH. Three out of 10 patients with AIH-PBC overlap syndrome were positive for ANA and AMA/AMA-M2. Conclusion Since AILD is not rare in Chinese, its diagnosis should be based on the clinical presentation, biochemical, immunological and histologic changes.

The basic function of vascular endothelial growth factor (VEGF) is to promote vascular growth. Recent studies show that VEGF plays a vital role in various thyroid diseases through prompting angiogenesis. But the function of VEGF and specific change condition in different thyroid disease still needs further explorations. This review mainly focuses on the molecular characteristics and clinical application of VEGF.

Vascular endothelial growth factor (VEGF) is a glycoprotein that promotes endothelial regeneration, stimulates formation of collateral blood vessels and increases vascular permeability. The purpose of this study was to measure the peripheral blood plasma level of VEGF and FT3, FT4, TSH and to analyze the correlation of the level of VEGF and TSH, FT3, FT4, age and gender in the patients of hyperthyroidism. The relationship between hyperthyroidism and VEGF was investigated as well. The plasma level of VEGF in 45 hyperthyroidism patients and 27 healthy persons were measured by enzyme-linked immunosorbent assay (ELISA), while plasma FT3, FT4, TSH were detected by chemiluminescence. The result showed that the plasma level of VEGF in hyperthyroidism patients [(92.53 +/- 62.38) pg/mL] was significantly lower than that in the control group [(158.28 +/- 77.15) pg/mL] (P < 0.01). The plasma level of VEGF correlated with age, and that of those over 40Y was significantly higher than that of 40Y or younger (P < 0.05) in healthy group. Whereas there was no correlation among VEGF, TSH, FT3, FT4, age and gender in hyperthyroidism patients (P > 0.05). These results suggested that the peripheral blood plasma level of VEGF in hyperthyroidism patients was significantly lower than that in the control group. Further experimental investigations are needed to estimate the relationship between VEGF and hyperthyroidism.

Because of the unobvious early symptoms and low 5-year survival rate, the early diagnosis and treatment is of great significance for patients with non-small cell lung cancer. Glucose transporter-1 is the most widely distributed glucose transporters in various tissue cells in the human body, whose expression in non-small cell lung cancer is closely related to the histological types, lymph node metastasis, degree of differentiation, progression and prognosis.

Chronic kidney disease (CKD) is now recognized as a worldwide public health challenge, and the incidence rate and hospitalization rate have significantly increased in recent years. Without prompt diagnoses and effective treatment in the early renal function damage of CKD, the symptoms will continue to worsen and eventually develop into end-stage renal disease. Functional imaging techniques such as single photon emission computed tomography (SPECT), contrast-enhanced ultrasound (CEUS), computerized tomography perfusion (CTP), and magnetic resonance perfusion weighted imaging (MR-PWI) could be used to quantitatively analyze renal perfusion and renal filtration function. Their diagnostic values are increasingly evident and have become the research hotspot in evaluating renal function. The aim of this review is to briefly evaluate the research and application advances in the early renal function damage assessment of CKD, so as to raise the efficiency of clinical applications.
