Objective To explore the expression and mechanisms of MMP-9 in vascular remodeling of two-kidney and one-cliped hypertension rats. Methods Male Wistar rats were randomly divided into sham operation group( n = 10), two-kidney and one-clip model (2KIC) group ( n = 10) and telmisartan group ( n = 7 ). Telmisartan group were injected with telmisartan every day. The blood pressure was determined every week. The morphologic change of carotid artery and thoracic aorta was observed with HE stainning 8 weeks after treatment with telmisartan.Arteries was performed to evaluate the expression of MMP-9 with immunohistochemisty. Results The blood pressure,vessel wall,and the expression of MMP-9 in model group were significantly higher than that of control group.Telmisartan nearly normalized arterial pressure and suppressed all these changes. Conclusion MMP-9 was related to vascular remodeling and Telmisartan could regulate vascular remodeling in 2-kidney and 1-cliped hypertension rats by inhibiting the pathway of MMP-9.

selenomethionine.Although the structure of selenomethionine and methionine are similar,the electron supply ability of selenomethionine is lower than that of methionine.Conclusion Methionine as electrons provider could accelerate the photolysis of VB2 to generate ?O 2,but selenocystine,selenomethionine and cystine could directily scavenge ?O 2 generated by VB2.

Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.

Objective To learn the control status of iodine deficiency disorders in Baoji City of Shaanxi Province.Methods From 2009 to 2011,according to the National Iodized Salt Monitoring Program,the iodized salt was monitored,and thyroid was examined in 12 counties(areas) of Baoji City.According to rural and urban area stratification,60 children aged 8 to 10 were selected in each county(district),and their urine samples were collected for determination of iodine content.In 2011,per capita daily salt intake was surveyed by the three weighing method at children's home whose urine was collected.Chencang Area,Fufeng County and Taibai County,representatives of Baoji City different geomorphic features were selected for investigation of water iodine,and urinary iodine of pregnant and lactating women,and 15 people were selected in each county (district).Results From 2009-2011,in the 12 counties(areas) in Baoji City,the coverage rate of iodized salt was all 100.00％(3468/3468); the qualified rate of iodized salt and the consumption rate of qualified iodized salt were all ＞ 99.00％.Children's goiter rate was 3.41％(87/2548),3.06％(77/2520) and 3.33％(84/2520),and they were all less than that of the national standard (＜ 5％).Medians of urinary iodine of 8-10 years old children were 368.20,293.80 and 332.50 μg/L,respectively,and the ratios of urine iodine ≥300 μg/L were accounted for 66.42％ (797/1200),48.05％(692/1440) and 56.67％(816/1440),respectively.Median urinary iodine of pregnant women was 301.81 μg/L and lactating women was 329.79 μg/L.A total of 1116 households were investigated,the median of per capita daily salt intake was 8.9 g.Eighteen water samples were collected,range of water iodine value were 0.60-10.25 μg/L.Conclusions Iodine nutrition in general population of Baoji City is exceeded the optimum level,and the current iodized salt concentration has some down space,but fully consideration should be taken on iodine needs in different iodine deficiency areas and among different groups of people.

Objective To study the influence of high-fluoride on thyroid function and brain damage. Methods Thirty-six Wistar rats were randondy divided, according to weight and gender into 3 groups(12 rats each), i.e. control group, high fluoride group, and high fluoride plus thyroid tablet treatment group. The rats were fed with normal tap water containing no more than 5 mg/L NaF and the tap water added 100,100 mg/L NaF, respectively. After 7 months of experiment, the rats in high fluoride plus thyroid tablet treatment group were given with 0.04% thyroid tablet( 1.8 ml·kg~(-1)·d~(-1)) by gastric perfusion for three weeks. The contents of TT_3 and TT_4 in serum were detected by radio-immunological assay; the histomorphology in thyroids and brains were observed under microscopy; and the protein level of NMDAR2B subunit of glutamate receptor in the hippocampal CA1 and CA3 was measured by immunohistochemistry. Results As compared to the values of TT_3 and TT_4 in serum of rats in control group[ (0.97 ± 0.15), (84.03 ± 12.45)nmol/L], TT_3 and TT_4 in high fluoride group were obviously lower [(0.24 ± 0.07), (15.16 ± 2.08)nmol/L, all P < 0.01]; while no changes in TT_3 and TT_4 were detected in high fluoride plus thyroid tablet treatment group[ (1.02 ± 0.19), (85.63 ± 9.55)nmol/L, all P < 0.05] as compared to controls, but higher than those in high fluoride group(all P < 0.01 ). The pathological changes including partial hyperplasy, arrangement disorder, atrophy, and decreased colloid of the thyroid follicular epithelial cells in high fluoride group were observed under microscopy. In high fluoride plus thyroid tablet treatment group, the degree of the thyroid cellular hyperplasy was relatively slight as compared to high fluoride group. The swelling and disarrangement of neurons in the hippocampus were observed in high fluoride group, whereas the changes of the neurons were not so obvious in high fluoride plus thyroid tablet treatment group. The grey values of NMDAR2B positive cells in the hippocampal CA1 and CA3 in high fluoride group(167.05 ± 7.31 ) were significantly increased as compared to controls (92.53 ± 9.67 ) or high fluoride plus thyroid tablet treatment group( 101.66 ± 12.21, all P < 0.01 ). Conclusions High fluoride can induce the decreased function and changed histomorphology in thyroid and result in pathological damages in the brains of rats. However, treated with thyroid tablet to those having damages induced by high fluoride, the thyroid function and morphology can be normal, and the brain damages can be alleviated. The results indicate that hypothyroidism caused by high fluoride might be an important participating factor in brain damages caused by fluorosis.

Granulocyte colony-stimulating factor (G-CSF) has been demonstrated to have neuroprotective effects in rat model with focal cerebral ischemia through anti-apoptotic pathways and by promoting proliferation of neural stem cells. In the present study, we examined the neuroprotective effect of G-CSF in an acute focal cerebral ischemia rat model with lipid metabolism disorder. Eighty male SD rats were randomly divided into normal diet control group (NC group) and high-fat diet group (HFD group) (n = 40 in each). In HFD group, rats were fed on high fat diet to induce atherosclerosis. After 29 days, 4 rats from each group were sacrificed to evaluate the effects of different diets, and the middle cerebral artery occlusion (MCAO) was performed in the rest of the rats. MCAO rats received either G-CSF (50 μg·kg(-1)·mL(-1)) or phosphate buffered saline (PBS) injection through the external jugular vein for 5 days, which was followed by 5-bromo-deoxy uridine (BrdU, i.p., 50 mg/kg) injection for another 7 days. To evaluate the effects of G-CSF treatment on neurological function, the modified neurological severity score (mNSS) was calculated. The vascular distribution, ischemic cells proliferation, cell apoptosis and the expression of vascular endothelial growth factor (VEGF) were measured to determine the effects of G-CSF treatment. Our results showed that G-CSF-treated rats had a lower mNSS than PBS-treated rats in both NC group and HFD group. G-CSF injection promoted endothelial cell proliferation and vascular regeneration, and inhibited cell apoptosis. The serum and tissue levels of VEGF were significantly increased after G-CSF treatment. It is concluded that G-CSF exerts its neuroprotective effect in focal cerebral ischemia rats with hyperlipidemia by enhancing angiogenesis, promoting cells proliferation, decreasing cell apoptosis, and increasing local VEGF expression.

Objective To investigate the staging significance of PET-CT in multiple myeloma,and to observe the relationship between baseline PET-CT and clinical parameters in multiple myeloma.Methods 78 cases newly diagnosed MM patients were selected from the Department of Hematology,the Xinjiang Uygur Autonomous Region people's Hospital from March 2007 to February 2014,with average age 61.24 years old.The levels of hemoglobin,albumin,beta 2 microglobulin and lactate dehydrogenase were detected before the treatment.PET-CT was performed to measure SUVmax in the spine,pelvis and rib with an average of the SUVmax in each case,and the number of FDG-avid focal lesions in every patient was counted.The difference of the SUVmax or FLS in different stages and the relationship between SUVmax or FLS and clinical parameters in MM were observed.Results All the patients were divided into 3 stages depending on ISS staging.The average SUV values in 10 cases of stage Ⅰ,45 cases of stage Ⅱ and 23 cases of stage Ⅲ were 1.84±0.28,3.74±0.42 and 6.02±0.93,respectively,and SUV values was significantly different among different groups (P ＜ 0.05).SUV values were positively correlated with levels of beta 2 microglobulin (r =0.862,P ＜ 0.001) and lactate dehydrogenase (r =0.592,P ＜ 0.001),and negatively correlated with albumin (r =-0.762,P ＜ 0.001) and hemoglobin levels (r =-0.685,P ＜ 0.001).The number of lesions had a correlation with low hemoglobin,high lactate dehydrogenase and high beta 2 microglobulin (P ＜ 0.05).Conclusion PET-CT can reflect tumor burden to some extent,and has the guiding significance for MM stage,which contributes to developing individualized treatment programs.
