Objective To study the effects of different iodine intakes on rat iodine metabolism during pregnancy.Methods One hundred and fifty female Wistar rats (body weight 80-100 g) were randomly divided into five groups:control group(NI),lower iodine 1 and 2 groups(LI1 and LI2),High iodine 1 and 2 groups(HI1 and HI2) by weight,30 rats in each group.These rats were given deionized water containing different concentrations of iodine,50(NI),0 (LI1),5(LI2),3000(HI1) and 10000 μg/L(HI2),respectively.After 12 weeks,urine samples were collected before copulation.The rats were sacrificed at the first(6-7 days),second (12-13 days) and third trimesters(19-20 days),respectively,serum and amniotic fluid samples were collected.Urinary iodine and iodine level in the fetal amniotic fluid were measured by As3+-Ce4+ catalytic spectrophotometry.Serum iodine was measured by mild acid digestion method.Results The baseline medians of urinary iodine of LI1 and LI2 groups(5.96,15.92 μg/L) were significantly lower than that of the NI group(43.75 μg/L,all P ＜ 0.01),and the values of HI and HI2 groups(5263.96,20389.64 μg/L) were significantly higher than that of the NI group (all P ＜ 0.01).The median of urinary iodine during pregnancy was significantly lower than that of the baseline of no pregnancy(all P ＜ 0.01).The medians of urinary iodine of the NI group at the first and the second trimesters (28.97,34.34 μg/L) were significantly lower than that of the third trimester(42.31 μg/L,all P ＜ 0.01).The means of serum iodine of LI1 and LI2 groups[(3.68 ± 1.69),(10.45 ± 4.16) μg/L] were significantly lower than that of the NI group [(23.68 ± 3.85)μg/L,all P ＜ 0.05],and the means of serum iodine of HI1 and HT2 groups [(502.67 ± 97.03),(822.15 ± 139.45)μg/L] were significantly higher than that of the NI group (all P ＜ 0.01).Although the mean of serum iodine of HI group gradually decreased with the progression of gestation,the difference was not statistically significant(all P ＞ 0.05).The iodine levels in amniotic fluid of fetal rats at the second and the third trimesters in LI1 group(0.85,3.00 μg/L) were significantly lower than that of the NI group(3.56,7.91 μg/L,all P ＜ 0.01),but the difference was not statistically significant between the iodine level in amniotic fluid of fetal rats of the LI2 and the NI groups at the second and the third trimesters(all P ＞ 0.05).The iodine levels in amniotic fluid of fetal rats at the second and the third trimesters in the HI1 group(49.59,171.21 μg/L) were significantly higher than that of the NI group(all P ＜ 0.01).The iodine levels in amniotic fluid of fetal rats at the second and the third trimesters in HI2 group (98.76,544.77 μg/L) were significantly higher than that of the NI group(all P ＜ 0.01).The iodine level in amniotic fluid of fetal rats in the third trimester was significantly higher than that of the second trimester in all the groups (all P ＜ 0.01).The ratios of serum iodine and urinary iodine of the LI1 and the LI2 groups (1.29 ± 1.14,1.70 ± 1.01) were significantly higher than that of the NI group(0.51 ± 0.37,all P ＜0.01),and that of the HI1 and the HI2 groups(0.21 ± 0.07,0.11 ± 0.07) were significantly lower than that of the NI group (all P ＜ 0.01).The ratios of amniotic fluid iodine and serum iodine of the LI and the LI2 groups (0.19 ± 0.15,0.32 ± 0.17) were significantly higher than that of the NI group(0.13 ± 0.05,P ＜ 0.01),but the difference was not statistically significant between HI1 and HI2 groups(0.09 ± 0.03,0.11 ± 0.04) and NI group(all P ＞ 0.05).The ratio of amniotic fluid iodine and serum iodine of the third trimester was significantly higher than that of the second trimester(all P ＜ 0.05).Conclusions Different iodine intake leads to changes in the levels of maternal iodine metabolism in rats during pregnancy.There probably is a protection mechanism in the mother's body,which protects the mother and the fetal from injury by iodine excess or iodine deficiency.

Objective To observe the effect of different levels of iodine nutrition on rat maternal thyroid function during pregnancy.Methods A total of 225 Wistar rats one month after weaning were involved in the study(female 165,male 60,body mass 80 to 100 g).Female rats were randomly divided into six groups by body mass:control group(NI group),iodine deficiency 1 and 2 groups(LI1,LI2 groups),iodine excess 1 and 2 groups (HI1,HI2 groups),and the control of not pregnant group(NNI group).There were 30 rats in 1-5 groups and 15 rats in group 6.LI1,LI2 groups:low iodine diet + deionized water of no iodine or iodine-containing 5 μg/L; HI1,HI2 groups:normal diet + deionized water of iodine 3000,10 000 μg/L; NI,NNI groups:normal diet + deionized water of iodine-containing 50 μg/L.After 12 weeks,the females(except group 6) mated the male by 2 ∶ 1,and then each pregnant female rat was fed in a single cage.The female mice were sacrificed in the first(5 ± 2)d,the second (12 ± 2)d and the third trimesters of pregnancy (17 ± 2)d,respectively,and there blood samples and thyroid were obtained.Serum total thyroxine(TT4),free thyroxine(FT4),total triiodothyronine (TT3),free triiodothyronine (FT3) and thyroid stimulating hormone(TSH) were determined by radioimmunoassay and serum thyroglobulin(TG) and thyroid-binding globulin (TBG) were determined by enzyme-linked immunosorbent assay.Results ①Thyroid absolute quality and relative quality was compared among groups,and the differences were statistically significant (F =16.55,24.25,F ＜ 0.01 or ＜ 0.05).②At the first,the second and the third trimesters of pregnancy,the differences of maternal serum TT4 and FT4 between groups were statistically significant(F =5.02,13.41,17.39,41.89,23.72,48.64,P ＜ 0.01 or ＜ 0.05).Female rats in NI,HI1 and HI2 groups in different pregnant periods among inner groups were compared,and the differences of serum TT4 and FT4 were statistically significant(F=3.27,6.98,8.22,8.65,29.68,7.90,P ＜ 0.01 or ＜ 0.05).③ In the first and the third trimesters of pregnancy,maternal serum TT3 was compared among groups,and the differences were statistically significant(F=3.59,8.22,P ＜ 0.05 or ＜ 0.01) ; in the second and the third trimesters of pregnancy,maternal serum FT3 was compared among groups,and the difference was statistically significant(F =3.86,4.26,P ＜ 0.05 or ＜ 0.01).Female rats in NI,LI1 and HI1 groups in different pregnant periods among inner groups were compared,and the differences of maternal serum TT3 were statistically significant(F =8.77,7.11,6.28,P ＜ 0.01 or ＜ 0.05).④At the first,the second and the third trimesters of pregnancy,the differences of maternal serum TG and TBG were compared in groups,and the differences were statistically significant(F =5.47,3.62,9.35,4.15,13.16,22.78,P ＜ 0.01 or ＜ 0.05).The differences of maternal serum TG of HI1 group and of serum TBG of NI group in different pregnant periods among inner groups were statistically significant (F =3.18,7.94,P ＜ 0.05).⑤At the first,the second and the third trimesters of pregnancy,the differences of maternal serum TSH in groups were statistically significant(F =4.83,7.08,6.52,P ＜ 0.01); the differences of maternal serum TSH of all the 5 groups in different pregnant periods among inner groups were statistically significant (F =3.26,8.89,11.45,4.04,3.78,P ＜ 0.05).Conclusions Different levels of iodine nutrition can cause changes in thyroid function in rats maternal thyroid function during pregnancy; serum TT4,FT4 level decreases when iodine deficiency,and increase with iodine excess.Serum TT3,FT3 level of does not changed significantly due to compensatory regulation of the body.

Objective To study the effect of different levels of iodine nutrition on secretion of placental hormone in pregnant rats.Methods Two hundred and twenty five Wistar rats (165 female,60 male),weighing about 80 - 100 g were used in the study.Female rats were randomly divided into five groups according to their body weights:low iodine group Ⅰ(LⅠ),low iodine group Ⅱ (LⅡ),adequate iodine(control) group(Al),high iodine group Ⅰ ( HⅠ ),and high iodine group Ⅱ (H Ⅱ ),and 33 rats in each group.Animals in the low iodine groups were fed low-iodine diet,the iodine content was 13.46 μg/kg,in addition,these rats drank deionized water which containing potassium iodated,the dose was 0 and 5 μg/L,respectively.The rats of adequate and the two high iodine groups were fed normal diet,the iodine content was 22.00 μg/kg,they also drank deionized water,containing potassium iodated 50,3000,and 10000 μg/L,respectively.The rats mated after 3 months of feeding,and were respectively sacrificed at early pregnancy(5 ± 2)d,second trimester( 12 ± 2)d,and third trimester of pregnancy(17 ± 2)d,and then their serum was taken.Serum human chorionic gonadotropin(HCG),human chorionic thyrotropin(HCT),and progesterone were measured by enzyme-linked immunosorbent assay (ELISA).Results In the third trimester,the serum levels of rat HCG were significantly different between groups(F =4.16,P ＜ 0.05).The means of rats serum HCG of the two low iodine groups [ (16.08 ± 4.45),(17.43 ± 2.70)U/L] were significantly higher compared with that of AI group[ (13.68 ± 3.52)U/L] in the third trimester(all P ＜ 0.01 ).In the second and third trimester,the levels of rats serum HCT were significantly different between groups(F =3.59,3.40,all P ＜ 0.05).The means of rats serum HCT of HI group [(70.11 ± 10.97)μU/L] in the second trimester and HII group[(74.93 ± 13.22)μU/L] in the third trimester were higher than those of AI group[ (57.14 ± 12.56),(58.17 ± 8.54)μU/L] significantly(all P ＜ 0.01 ).There were statistical differences of the means of serum progesterone among trimester of pregnancy(F =4.06,4.43,all P ＜ 0.05).The level of serum progesterone of the third trimester[ ( 1462.80 ± 286.48 )pmoL/L] compared to those of the first[ (1929.93 ± 158.37) pmol/L] and the second trimester[ (1856.44 ± 542.08)pmol/L] was decreased significantly(all P ＜ 0.05) in LI group.In the control group,the level of serum progesterone of the second trimester [ (2046.45 ± 475.67)pmol/L ] was significantly higher than the first trimester[ (1714.39 ± 461.71 )pmol/L,P ＜ 0.05 ].Conclusions During pregnancy,placenta could promote HCG secretion under iodine-deficient conditions.In addition,the placenta increases the secretion of HCT under conditions of excess iodine.In the condition of severe iodine deficiency,the secretion of serum progesterone decreases,and further decreases with prolongation of pregnancy,but it is opposite to the change of HCG during pregnancy.This phenomenon could lead to harmful pregnant outcomes easily.

Background:The incidence of gastric cancer is gradually rising in recent years,long non-coding RNA taurine up-regulated gene 1 (TUG1)may have certain effects on the occurrence and progression of gastric cancer. Aims:To study the expression TUG1 in gastric cancer tissue and its effect on prognosis of patients with gastric cancer,and study the correlation between TUG1 and p27,cyclin D1. Methods:Surgically resected gastric cancer tissues and corresponding distal normal tissues of 48 gastric cancer patients from June 2013 to December 2013 at Qingdao Municipal Hospital were collected. qRT-PCR was used to detect the mRNA expression of TUG1,and its relationship with clinicopathological features was analyzed. Protein expressions of p27 and cyclin D1 were determined by Western blotting,and correlation with expression of TUG1 was analyzed. Kaplan-Meier was used to analyze the relationship between expression of TUG1 and prognosis. Results:The mRNA expression of TUG1 in gastric cancer tissues was significantly higher than that in corresponding normal tissues (6. 18 ± 0. 19 vs. 5. 09 ± 0. 16,P < 0. 05),and was not correlated with gender,age,tumor size,but correlated with lymph node metastasis,tumor differentiation and TNM staging (P < 0. 01). The protein expression of p27 was significantly decreased in gastric cancer tissues than in normal tissues (0. 1709 ± 0. 0212 vs. 0. 3087 ± 0. 0252,P < 0. 01),while protein expression of cyclin D1 was significantly increased (0. 3417 ± 0. 0271 vs. 0. 2417 ± 0. 0173,P < 0. 01),and the expression of p27 was negatively correlated with expression of cyclin D1 in gastric cancer tissues (r = - 0. 897,P < 0. 01). The expression of TUG1 was negatively correlated with expression of p27 (r = - 0. 730,P < 0. 01),and was positively correlated with expression of cyclin D1 (r = 0. 809,P < 0. 01)in gastric cancer tissues. The median survival time was shorter in gastric cancer patients with high-expressed TUG1 than in patients with low-expressed TUG1 (P < 0. 05). Conclusions:Long non-coding RNA TUG1 plays a role of cancer gene in the development of gastric cancer through p27 /cyclin D1 pathway. Detection of expression of TUG1 has important significance on the prediction of prognosis of gastric cancer patients.

OBJECTIVE: To investigate the patterns of antipsychotic use in China and to analyze the factors that influence antipsychotic prescriptions. METHODS: A standardized survey was conducted from May 20 to 24 2002 in five different regions of China with varying economic levels. The patterns of antipsychotic medication use were analyzed in a sample of 4,779 patients with schizophrenia. The survey gathered information on demographic characteristics, clinical profiles, and antipsychotic medications prescribed. Multiple logistic regression was used to analyze factors related to patterns of antipsychotic medication use. RESULTS: A plurality of patients with schizophrenia was treated with clozapine (39%); this was followed by risperidone, sulpride, chlorpromazine, perphenazine, and haloperidol. More than 56.3% of patients were treated with only one atypical antipsychotic. The mean daily dose of chlorpromazine was 365+/-253 mg (mean+/-standard deviation), and 6.5% of patients were treated with depot injections of typical antipsychotic medications. A total of 73.7% (n=3,523) of patients with schizophrenia received monotherapy, 24.8% (n=1,183) received two antipsychotics, 1.1% (n=52) received three antipsychotics, and one received four different antipsychotics. Patients often simultaneously received other classes of medications including anticholinergic agents, benzodiazepines, beta-blockers, antidepressants, and mood stabilizers. Economic status and clinical symptoms were the main factors that contributed to the patterns of antipsychotic prescription. CONCLUSION: The present study suggests that atypical antipsychotic medications, especially clozapine, are the primary psychiatric treatments of choice in the management of schizophrenia in China. Moreover, the economic status and clinical profile of the patient are the major factors affecting the prescription of antipsychotic medication.
