Thyroid hormones play important roles in growth, development, and metabolism of various cells and tissues. It has been assumed for a long time that thyroid hormones are lipophilic and enter cells by passive diffusion, but it has become increasingly clear that cellular uptake and efflux of thyroid hormones are mediated by transporters. The discovery of these thyroid hormone transporters will lead to a better understanding of the tissuespecific regulation of thyroid hormones.

“The guideline for the diagnosis and management of thyroid diseases during pregnancy and postpartum in China” written by Chinese Society of Endocrinology and Chinese Society of Perinatal Medicine is now formally published.This guideline was written following the principles of “based on the national conditions,evidencebased medicine,being innovative and realistic,and resource sharing”.It is modeled on the guideline issued by American Thyroid Association in 2011,joining the research of domestic scholars and combining with the actual situation of domestic clinical work and maternal and child health.This guideline contains 11 chapters,taking question terms and recommendation terms in the model,and a total of 68 problem terms and 57 recommendation terms.This paper deeply discusses the problems about the diagnosis and treatment of subclinical hypothyroidism during pregnancy,as well as the importance of establishing gestation-specific TSH reference interval.

Guidelines on the Diagnosis and Treatment of Thyroid Nodules and Differentiated Thyroid Carcinomas is written by Chinese Society of Endocrinology,Chinese Society of General Surgery Endocrinology Group,China Anti-Cancer Association Head and Neck Tumor Professional Committee,and Chinese Society of Nuclear Medicine.The guideline has systematically established a series of standards related to thyroid nodules.It reflects the scientific spirit of multidisciplinary cooperation and mutual understanding.

Objective To investigate the effect of problem-based learning(PBL) combined with traditional teaching in the teaching of electrocardiogram (ECG) diagnosis. Methods Totally 80 2011 grade clinical medicine students were enrolled and randomly divided into study group and regular group. Traditional teaching method was implemented in regular group while PBL com-bined with traditional teaching was applied in study group. Effect was observed;measurement data were analyzed by independent samples t test and were expressed as mean ± standard deviation x±s;enumeration data were analyzed by χ2 test. P<0.05 signifies statistical differences. Results Satisfaction degree of students towards teachers was 95.0%(38/40) in study group and was 80.0%(32/40) in regular group with statistical significances between two groups(P=0.001). Satisfaction degree of students towards teaching method was 100 . 0%( 40/40 ) in study group and was 87 . 5%(35/40) in regular group with statistical significances between two groups (P=0.000). Operating skills, theoretical knowledge and ECG analysis capabilities scores were significantly higher in study group than in regular group with statistical differences(P=0.012, P=0.021, P=0.016). Conclusions Implementing PBL teaching combined with traditional teaching can achieve significantly better teaching effect than traditional teaching, therefore it is worthy of application and promotion.

Objective To understand correctly the hook like effect of the immune transmission and transmission turbidity in the automatic biochemical analyzer and the prevention of the hook like effect .Methods First ,it had the function set of measurement linear range of the upper limit of the instrument and the instrument automatic dilution redo ,and then ,had determination of excee‐ding the upper limit of measurement range and artificial dilution before the sample setting .Results The group average value was 2 .49 g/Lbefore the determination setting ,3 .31 g/L after the determination setting ,and 3 .33 g/L artificial dilution determination . Conclusion High dose hook effect makes the strong positive to weak positive samples of measurement by error ,even false negative results ,and high concentration sample makes low value .So the set of samples and dilution to determination of instrument ,measured values are more close to the true value .

Guidelines of the American Thyroid Association (ATA) proposed two diagnostic criteria for subclinical hypothyroidism during the first trimester of pregnancy:criterion 1 was based on the pregnancy-specific TSH reference range and criterion 2 on serum TSH＞2.5 mIU/L level with normal serum FT4.According to the results of the Subclinical hypothyroidism during early pregnancy study,author proposed that criterion 2 is not appropriate for Chinese pregnant women because the TSH concentration has become significantly higher in whole Chinese population.By using criterion 2,the prevalence may be as high as 27.8％,which may result in over-diagnosis and over treatment.

Neuroblastoma is one of the solid tumors in children which easily metastasizes to bone.It causes radiographic appearance of osteoclastic reactions after bone metastases.In the process,neuroblastoma cells,osteoblasts and bone stromal cells secrete a series of related factors to promote bone metastases.In this paper,the progress of the mechanism in bone destruction caused by neuroblastoma is reviewed.

Five mongrel dogs were used to investigate the dynamic changes of beta-cndo-rphin-Uke-immunoriactivity(ir-?-EP)and thdr correlation with hemodynamics during intestinal ischemia shock.It was shown that plasma levels of ir-?-EP were increased significantly during shock and were significantly correlated with the decrease in MAP, CO, SV,and CI.Our results give the direct evidence that endogenous opiate beta-endorphin is involved in the cardiovascular pathophysiology of intestinal ischemia shock.

hypothyroidism is a common subclinical disease in endocrinology. Its diagnosis is based on an elevated serum TSH but normal FT 4 levels. The adverse outcome of subclinical hypothyroidism is progressing to overt hypothyroidism with an increased risk for atherosclerosis and myocardial infarction . Two factors may affect the development of overt hypothyroidism: the levels of serum TSH and thyroid autoantibodies and both factors have additional effects on the outcome. The benefits of treatment with T 4for preventing the development of overt hypothyroidism is not yet certain; subclinical hypothyroidism is a strong indicator of risk for atherosclerosis and myocardial infarction, just like other known major risk fators such as hypercholestrolemia, hypertension, smoking and diabetes (odds ratio for aortic atherosclerosis 1.9; odds ratio for myocardial infarction 3.1). The treatment with T 4 for the patients could reduce the levels of serum cholesterol. The effects of subclinical hypothyroidism in pregnant women on the IQ of their children have been widely focused. According to the results from a published epidemiological study, the normal reference values of TSH, thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb) detected by immunochemiluminesence assay (ICMA) method and the cut-off values of TPOAb and TgAb associated with thyroid diseases have been proposed.
