Journal of Biomedical Engineering 2014;31(3):552-557
According to the inclusion and exclusion criteria, we searched for relevant original articles in some big Chinese and English databases. The qualities of the studies were evaluated with QUADAS quality assessment tool. A software program, Meta-disc, was used to obtain the pooled estimates and heterogeneity test for sensitivity, specificity, SROC curve, and so on. Finally the 17 article were included. On a per-patient basis, the pooled sensitivity (SEN), specificity (SPE), positive likelihood ratio (LR+), negative likelihood ratio (LR-), diagnostic odds ratio (DOR), Q*, SROC area under curve for 99mTc-MDP bone scan and computed tomography (CT) were 0. 87 and 0.99, 0.81 and 0.98, 3.88 and 13.86, 0.2 and 0.03, 27.73 and 612.17, 0.8418 and 0.9732, 0.9097 and 0.9952, respectively. On a per-focus basis, the pooled SEN, SPE, LR+, LR-, DOR, Q*, SROC area under curve for 99mTc-MDP bone scan was 0.86, 0.97, 13.32, 0.16, 102.4, 0.8944, 0.9528, respectively. For CT, only 1 article were included. This paper demonstrate: whether 99mTc-MDP or CT both have high diagnostic efficiency for bone metastase of breast cancer.

2.Application progress of 18F-FDG positron emission tomograph in differentiated thyroid cancer.
Journal of Biomedical Engineering 2014;31(2):445-451
Positron emission tomography (PET) is a highly sensitive and low invasive technology for cancer biological imaging. Integrated PET/computed tomography (PET/CT) cameras combine functional and anatomical information in a synergistic manner that improves diagnostic interpretation. The role of 18F FDG PET/CT in differentiated thyroid cancer (DTC) is well established, particularly in patients presenting with elevated thyroglobulin (Tg) levels and negative radioactive iodine scan. This review presents the evidence supporting the use of 18F FDG PET/CT throughout the diagnosis and management of thyroid cancer, and provides suggestions for its clinical uses.

Objective To assess the effect of radioiodine-131 (131Ⅰ) on treatment of pulmonary metastases from differentiated thyroid carcinoma and the main prognostic factors. Methods Five databases were retrieved and all published studies which analyzed the effect of 131Ⅰ on pulmonary metastases from differentiated thyroid carcinoma and the main prognostic factors were systematically reviewed. The data about the impact of 131Ⅰ treatment and the main prognostic factors on the 5-yr and 10-yr survival rates of the patients were abstracted. RevMan 4.2 software was used to statistically analyze. Results Eleven retrospective cohort studies were included. The pooled results suggested that the 5-yr survival rates of the patients who received 131Ⅰ therapy and who did not received 131Ⅰl therapy were 74.9% and 27.1% , respectively ;The lO-yr survival rates(P<0.01)of the two groups were 60.8% % 12.2% , respectively;The difference between them had statistical significance (P<0.01). The 5-yr and 10-yr survival rates of the patients only with pulmonary metastases were higher than those of the patients with multiple metastases (P<0.01). The 5-yr (P = 0.01) and 10-yr (P = 0. 002)surviv10al rates of the patients only with papillary thyroid carcinoma were higher than those of the patients with follicular thyroid carcinoma. The 5-yr and 10-yr survival rates of male and female patients were similar(P>0.05). Conclusions 131Ⅰ treatment increases the 5-yr and 10-yr survival rates of patients with pulmonary metastases from differentiated thyroid carcinoma. The extent of metastases and the histologie type of differentiated thyroid carcinoma are two main predicting factors of prognosis. The 5-yr and 10-yr survival rates of patients are not influenced by gender.

Objective To investigate the biokinetics of 131 I and its absorbed dose in patients with metastatic DTC. Methods Forty?one patients with metastatic DTC who were referred to 131 I therapy were prospectively recruited from September 2009 to September 2011. Scintigraphic images were serially acquired after the ingestion of 131I (3.70-9.25 GBq) to assess the biokinetics. CT was used to measure the masses of the DTC lesions. Calculation of absorbed doses to DTC lesions was based on the Medical Internal Radiation Dosimetry formula of the Society of Nuclear Medicine and Molecular Imaging. Kruskal?Wallis rank sum test was used to compare the differences of absorbed dose among different tumor deposits. Results In total, 59 io?dine?avid metastatic lesions (35 in cervical lymph node, 17 in lung and 7 in bone) in 41 patients were evalu?ated and the mean absorbed dose of DTC lesions was (10.4±6.5) Gy/GBq, with range of 0.1 to 136.2 Gy/GBq. The median absorbed dose was 11.3 Gy/GBq for lymph node metastase, 10.1 Gy/GBq for lung metastases and 9.6 Gy/GBq for bone metastases. There were no statistically significant differences in absorbed doses a?mong the metastases of lymph node, lung and bone ( Z=0.907, P>0.05) . Conclusion A wide inter?lesion variation of absorbed dose to metastatic DTC is observed.

8.Genetic alterations in MAPK and PI3K/Akt signaling pathways and the generation, progression, diagnosis and therapy of thyroid cancer.
Journal of Biomedical Engineering 2012;29(6):1221-1225
The mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) and phoshoinositide-3-kinase/protein kinase B (PI3K/Akt) signaling pathways play a major role in regulating cell growth, proliferation and apoptosis, via transmission of cell signals to cell nucleus. The genes, coding the MAPK/ERK and PI3K/Akt signaling cascade proteins, are significantly mutated in thyroid cancer. Genetic alternations contribute to aberrant activations and interaction of MAPK/ERK and PI3K/Akt signaling pathways in consequence of malignant follicular cell transformation and progression. This review focuses mainly on the role of genetic alterations in coding MAPK/ERK and PI3K/Akt signaling pathway proteins in generation, progression and diagnosis of thyroid cancer. Moreover, it additionally points out a therapeutic potential in restoring iodine avidity of thyroid cancer cells for radionuclide targeted treatment, by synergistically inhibiting activity of signaling pathways.

9.Advances in research on radioiodine therapy of carcinoma mediated by gene transfer technology.
Journal of Biomedical Engineering 2010;27(5):1187-1192
Radioiodine therapy of carcinoma could be mediated by transferring the genes which participate in the process of iodine metabolism in thyroid. The correlative genes are sodium/iodine symporter gene, thyroid peroxidase gene and the specific thyroid transcription factors, and others. The objective gene can specifically express in carcinoma by inserting the tissue-specific promoter/enhancer upstream of them, so radioiodine could be used to treat varied carcinomas. The radioiodine uptake in carcinoma cells was obviously increased and the radioiodine therapy of carcinoma was effective after those genes had expressed in carcinoma cells. The main problem was that the effective half-time of radioiodine in cells was too short to produce the ideal effect of radioiodine therapy. Moreover, 211At and 188Re could be transferred by sodium/iodine symporter and they could be used to treat the carcinoma that is capable of radioiodine uptake.

10.Clinical application of recombinant human thyroid-stimulating hormone in management of differentiated thyroid carcinoma.
Journal of Biomedical Engineering 2012;29(3):588-592
Traditionally, during the follow-up and in order to receive 131 I therapy, patients with differentiated thyroid carcinoma (DTC) have to withdraw from using thyroid hormone. The hypothyroidism induced by hormone withdrawal can negatively affect the quality-of-life (QOL) of DTC patients. Without the hormone withdrawal, recombinant human thyroid-stimulating hormone-aided management of DTC patients can effectively obviate the consequences of hypothyroidism. This review will focus on the clinical application of recombinant human thyroid-stimulating hormone (rhTSH) in the management of DTC patients.
