Objective By comparing the detection rates of subclinical thyroid diseases in women(pregnant,lactating and child-bearing age)between iodine deficient regions (supplied iodized salt)and water-borne iodine excess regions (consumed non-iodized salt),and to find the different prevalence of subclinical thyroid disease between two regions under their different iodine source and iodine levels, and to provide reference for screening susceptible population with iodine-related thyroid diseases.Methods The iodine deficiency but salt iodine surpplying regions were selected from six provinces in our country,the local people who were pregnant women,lactating women and 18 to 45 years old women of child-bearing age,a total of 991 cases were investigated.The iodine nutrition levels of the pregnant women were grouped by <150,150-249,and ≥500μg·L-1;the iodine nutrition levels of the lactating women were grouped by <100 and ≥100μg·L-1 .The high water-iodine regions in Shanxi Province were selected,and according to the water-iodine levels 50-99,100-149,149-299,and more than 300μg·L-1 four regions were selected;20 cases of three kinds of people mentioned above were selected in each region,a total of 241 cases.The blood and urine samples were collected, and the serological thyroid function indexes were detected by chemiluminescence immunoassay method or radioimmunity method, and the urine-iodine was detected with cerium catalytic spectrophotometric method. Results In iodine deficient regions and water-borne iodine excess regions, the concurrence rates of subclinical hypothyroidism(hypothyroidism for short)and thyroid antibody positive of women were 2.32% and 4.98%,respectively;accounting to about 1/3 to 1/2 of those subclinical hypothyroidism population.The prevalence rates of subclinical thyroid diseases in the women population between the two regions were 27.55% and 34.85%,respectively;nearly accounting for 1/3 of the women population.The subclinical hypothyroidism detection rates of the three populations in high water iodine regions were significantly higher than those in iodine deficient regions(P<0.05).The lactating women’s detection rates of thyroid antibody positive and subclinical hypothyroidism with antibody positive in high water iodine regions were significantly higher than those in iodine deficient regions(P<0.05).With different iodine sources,when took appropriate iodine,there was no statistical difference of the detection rates of subclinical thyroid diseases among three kinds of women(P>0.05). With the increase of iodine exposure levels,the prevalence of women who suffered from subclinical hypothyroidism and thyroid antibody positive was increased,the coincidence rate was also increased.The detection rates of low T4 concentration and total subclinical thyroid disease of pregnant women in iodine nutrition<100μg·L-1 group were significantly higher than those in iodine nutrition 250-499μg·L-1 group (P<0.05).The detection rates of low T4 concentration and total subclinical thyroid disease of lactating women in iodine nutrition <100μg· L-1 group were significantly higher than those in iodine nutrition >100μg·L-1 group (P<0.05).Conclusion When the iodine intake is appropriate, iodine intakes from salt or from water have no effect on subclinical thyroid diseases. When the iodine intake increases,the prevalence of subclinical thyroid diseases will increase too.

OBJECTIVETo investigate the changes in the number and distribution of myoepithelial cells during atrophy of the rat parotid gland.
METHODSAtrophy of the right parotid was induced by ligating the right stensen duct of rats, histological changes of parotid glands were examined by hematoxylin-eosin (HE) staining during each step of glandular atrophy at the time of 0 (control), 1, 3, 5, 7, 14, 21, 30, 60, 100, and 150 days after ligation. Immunohistochemical labelling was performed to study the changes in number and distribution of myoepithelial cells during atrophy of the rat parotid gland.
RESULTSHistological analysis showed disappearance of the acini at 5 d and gradual decrease and fibrosis of the glandular lobules accompanied by the occurrence of duct-like structures. Quantitative analysis of myoepithelial cells showed significant increase in number up to day 5 after ligation, then followed by gradual increases at a low level, at last it was followed by a rapid decrease after the total number reached the peak in 100 days. In addition, the acini and intercalated ducts were covered by myoepithelial cells ranged from the shape of spindle to stellate during the early phase of atrophy, while spindle-shaped myoepithelial cells were located at the periphery of duct-like structures in the later phase of atrophy.
CONCLUSIONMyoepithelial cells proliferated rapidly up to day 5 after ligation, then followed by gradual increase at a low level, at last it was followed by a rapid decrease after the total number reached the peak in 100 days.

Objective: To investigate the detection rates and inlfuencing factors of atrial septal defect (ASD) and ventricular septal defect (VSD) among neonates in two cities of East China and to provide scientiifc basis for the prevention, diagnosis, treatment and monitor of ASD and VSD. Methods: 2100 newborns with gestational age of at least 28 weeks were recruited consecutively from each city between 2013-09 and 2014-11. Data related to ASD and VSD were collected by questionnaires and echocardiographic screening was conducted within 7 days after birth. Results: A total of 4152 neonateswere examined with gestational age of (39.03 ± 1.29) weeks, among whom 2189 were male infants (52.72%), and age of mother was (26.32 ± 4.10) years old. Detection rates of ASD and VSD were 60.5‰ and 12.8‰ respectively, showing no significant difference between genders (P>0.05). Multivariate logistic regression analysis showed that maternal pre-pregnancy BMI and home decoration were the inlfuencing factors of ASD and maternal drug use in early pregnancy was the inlfuencing factor of VSD among newborns. Conclusions: Detection rates of ASD and VSD among neonates were relatively high in two cities of East China. Early screening is importtant to reduce the incidence of ASD and VSD and improve the prognosis.
