Objective Toinvestigate iodine nutrition,thyroid volume and function of children and women in high water iodine areas,and to discuss the cut-off point of water iodine level where should be defined as iodine excessive areas.Methods In iodine excessive townships in Xiaodian and Qingxu Counties of Taiyuan City,all villages were divided to 4 groups according to the concentration of iodine in drinking water:50 ～ ＜ 100 μg/L (Group A),100 ～ ＜ 150 μg/L(Group B),150 ～ ＜ 300 μg/L(Group C) and ≥300 μg/L(Group D),and 2-3 villages were randomly selected from each group as investigation sites.Two hundred children aged 8-10 and 60 women (20 pregnant women,20 breasffeeding women and 20 women of childbearing age,respectively) were sampled.Drinking water,edible salt and once random urine samples for each studying object were collected,and the iodine content was measured.The goiter volume of children aged 8-10 and triiodothyronine (FT3),free thyroxine (FT4),thyroid stimulating hormone (TSH) of women were determined.Results Totally 708 children and 236 women were selected as respondents who ate non-iodized salt.Iodine content in drinking water of children in groups A,B,C and D was 73.8,144.7,258.5 and 501.0 μg/L,respectively,and that of women was 73.8,144.7,242.7 and 485.9 μg/L,respectively.Median urinary iodine of children in groups A,B,C and D was 274.3,312.8,455.6 and 793.5 μg/L,respectively,and that of women was 238.3,235.2,371.6 and 641.6 μg/L,respectively.The median urinary iodine of children and women increased with increasing water content of iodine.The goiter rate of children was 5.6％ (11/196),13.2％ (25/189),12.6％ (20/158) and 10.9％ (18/165) for each group,respectively,which also increased with increasing water content of iodine.In groups A,C and D,the FT3 and FT4 levels[pmol/L:(3.70 ± 0.59),(14.01 ± 2.44); (3.43 ± 0.57),(12.87 ± 2.12); (3.42 ± 0.47),(12.66 ±1.78)] in pregnant woman were lower than those in breasffeeding women[pmol/L:(4.26 ± ±0.57),(14.73 ± 2.36;(4.28 ± 0.40),(14.77 ± 1.19); (4.36 ± 0.65),(15.66 ± 2.84)] and women of childbearing age[pmol/L:(4.80 ±0.50),(17.47 ± 2.11); (4.21 ± 0.48),(15.83 ± 1.64); (4.26 ± 0.52),(15.53 ± 1.81)].With increasing water content of iodine,FT4 level was decreasing and TSH level was increasing gradually in women.Conclusions When water iodine exceeds 100 μg/L,goiter rate of children has increased significantly.Iodine excessive women and children have appeared one after another with increasing water content of iodine.Women incidence of subclinical hypothyroidism risk has increased with increasing water content of iodine,and the detection rate of subclinical hypothyroidism is significantly higher when water iodine is higher than 300 μg/L.The cut-off point of iodine excessive areas should be descend from 150 μg/L to 100 μg/L.

Objective To investigate the relationships of nuclear factor кB (NF-кB) activation with protein kinase B (Akt) and glycogen synthase kinase 3β (GSK-3β) during amyloid-β (Aβ) (25-35) -induced apoptosis in pheochromocytoma cells (PC12 cells) of rats. Methods Apoptosis in PC12 cells was induced by A(25-35). The activities of Akt, GSK-3β and NF-кB were analyzed in this process. The Akt and GSK-3β pathways were blocked by their specific inhibitors, respectively, and the relationships of Akt and, GSK-3β with NF-кB during Aβ(25-35)-induced apoptosis in PC12 cells were determined. Results Aβ(25-35) induced apoptosis was in a dose-dependent manner. With 0, 5, 10, 20 μmol/L and 40 μmol/L Aβ(25-35) treaing for 48 h, the apoptosis rates of PC12 cells were (3. 01 ± 0.03)%, (3.08 ±0.03)%, (25.32 ± 0.76)%, ( 42.88 ± 0.60 )% and ( 60.85 ± 2.39 )% , respectively. Compared to control, both Akt and GSK-3β were suppressed during apoptosis, at meantime NF-кB was activated. The inhibited Akt activity by wortmannin leaded to decreased NF-кB activatity and increased GSK-3β activatity. Suppression of GSK-3β with its specific inhibitor LiCl caused the decreased activation of NF-кB too, but it had no significant influence on Akt activity. Conclusions These results suggest that both Akt and GSK-3β are upstream regulators of NF-кB. They co-regulate the activation of NF-кB during Aβ(25-35)-induced apoptosis in PC12 cells. This study contributes to the theoretical base for the pathogenesis of Alzheimer disease (AD) , and provides a new idea to AD prevention and therapy.

Objective To construct the eukaryotic expression vector for mouse microRNA miR-21 and identification its expression activ-ity in 293 cells. Methods The genomic sequence containing pre-miR-21 was amplified from mouse genomic DNA by PCR and cloned into the pRC/CMV plasmid. The constructed recombinant plasmid pRC/CMV-mmu-miR-21 was transfected to 293 cells by lipofectamine 2000, and the stably transfected cells were screened with G418,from which total RNA was extracted for detecting the expression of mature miR-21 by northern blot. In the meantime,a luciferase report plasmid examing the activity of miR-21 named pmiR-21-Luc reporter was also construc-ted,and luciferase activity analysis indicated the product of pRC/CMV-mmu-miR-21 indeed had biological activity. Results Both restriction enzyme digestion analysis and sequencing proved the recombinant plasmids were constructed correctly. The miR-21 was highly expressed in the screened clones of 293 cells and it had good biological activity. Conclusion The eukaryotic expression plasmid of mouse miR-21 was successfully constructed,which laid the foundation of further investigation of the role of miR-21 during skin wound healing.

[ ABSTRACT] AIM:To investigate the effects of paeoniflorin ( Pae) on the functional responses induced by acute hypoxic insult in the rat cerebellar Purkinje cells ( PCs) .METHODS:The whole-cell patch clamp was used for the intra-cellular recording of PCs in the rat cerebellar slices to evaluate the changes of membrane potential, the excitability of PCs, and the parallel fibre ( PF)-PC excitatory postsynaptic currents ( EPSCs) upon acute hypoxic insult alone or with the pre-sence of Pae.RESULTS:PCs showed an initial hyperpolarization followed by brief depolarization and long lasting post-hy-poxia hyperpolarization after hypoxia exposure.Pae completely blocked hypoxia-induced hyperpolarization and decreased the amplitude and the duration of hypoxic depolarization.Hypoxia up-regulated the excitability of rat PCs.Pae didn’t show any significant effect on the hypoxia-induced hyperexcitability in PCs.Acute hypoxia induced long-term depression ( LTD) in rat cerebellar PF-PC EPSCs, and Pae partially reversed hypoxia-induced depression in PF-PC EPSCs.CONCLUSION:Pae significantly suppresses hypoxia-induced responses in rat PCs and probably increases the tolerance of rat PCs to acute hypoxia.

Objective To investigate the value of biliary tumor markers for differential diagnosis of the benign and malignant biliary tract diseases.Methods Tumor markers (CA19-9,CEA and CA242) examination and bacterial culture were performed in a total of 160 patients,who underwent therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for biliary diseases.Resuts There were significant differences between malignant group and benign group in bile and serum in the level of CA19-9,CEA and CA242 (P ＜0.05) ; Cut-off value,according to ROC curve,was 239 ku/l in CA19-9,40 ng/ml in CEA and 60 ku/ml in CA242,respectively.There were significant differences between the bile marker and the serum marker in sensitivity,accuracy,negative predicative value of CEA (P ＜ 0.05).No significant differences was found in specificity between the serum group and the bile group.There were significant differences in bile CA19-9 level between cholangiocarcinoma,pancreatic cancer,duodenal papilla carcinoma with carcinoma metastasizing to bile duct,and hepatocellular carcinoma (P ＜ 0.05).Both in benign group and malignant group,there were significant differences in CA19-9 level between infectious bile and noninfectious bile (P ＜ 0.05).Conclusion The level of CA19-9,CEA and CA242 in bile can be applied to differentiate benign and malignant biliary diseases.The bile tumor markers do not have advantage over serum tumor markers in specificity for diagnosis.Bile bacterial infection can result in the elevation of bile CA19-9 while it does not have impact on differential diagnosis.

Objective To explore the effect of long-term depleted uranium (DU)ingestion on testosterone production in rats, and its involvement mechanism. Methods Male and female rats (F0 and F1 respectively) for 160 days, respectively. The contents of testosterone (T), luteinizing hormone (LH), and follicle stimulating hormone (FSH) in serum were detected in 20 months of F0 generations, and 15 months of F1 generations. RT-PCR was used to analyze the levels of StAR mRNA and P450scc mRNA. Results Compared with the normal control group, the testosterone contents in exposed F0 and F1 generations increased, the lowest was 51.73 U/L, but those of LH and FSH decreased. The expression of StAR mRNA in the low-doze group of F1 generation (StAR/β-actin = 1.35) was up-regulated, down-regulated for other groups.compared with the normal control group (P450scc/β-actin = 0. 313), the expression of P450scc mRNA in the low- and high-dose groups of F0 generation were decreased (P450scc/β-actin = 0.21), and those in the low- and high-dose groups of F1generation were increased (P450scc/β-actin = 0.623) (P ≤ 0.01). Conclusion Long-term DU exposure inhibit the male reproduction by intervening the sexual hormone production through down-regulated the expression of StAR mRNA and P450scc roRNA.

Objective To assess if evaluating with Peabody's fine motor development scale with 4 degree grading is more sensitive than with 3 degree grading, and whether or not it is feasible to evaluate by quantization with monthly averages. Methods A total of 864 normal children aged 1 month to 60 months were evaluated with the Peabody scale using 4 degree grading and 3 degree grading. The development results were averaged by month to express the development. Results Both ways, the monthly averages of children 4-9 months old were higher than the others. The values obtained with 4 degree grading were lower than those with 3 degree grading in each functional area, and the difference was more obvious with increasing age, but the differences were not statistically significant. With 3 degree grading the total score was equal to the actual score after the age of 9 months, but with 4 degree grading this was not true until at least 18 months. Conclusions Evaluating with Peabody's fine motor scale with 4 degree grading and quantization using monthly averages is reliable and more sensitive than 3 degree grading.
