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 tissue stimulation of copper ions to the smooth muscle of murine terminal rectum.Methods In this study copper needle used for electrochemical therapeutic equipment was punctured into submucosal smooth muscle tissue of terminal rectum above the dentate line in 65 male rats.Rats were then divided into 5 groups (10 rats in each group) at random and sacrificed at 1, 3, 4, 6, 8 weeks after respectively, samples were sent for observation of macroscopic and microscopic tissue reaction.Results Rats had no abnormal histological change in the puncture points grossly. Undor microscope, mild edema was detected in the submucosal layer in 1 week group. Remarkable infiltration of inflammatory cells and lymphocytes subsided 3 weeks after, and disappeared five weeks after.Smooth muscle was normal microscopically in all groups.In contrast, platinum and steel needles caused infiltration of plasma cells and neutrophils, ulcers and small abscess formation in around puncture points.Conclusion Inflammatory reaction was induced after puncturing of copper needle into the tissues and the tissue reaction disappeared after 5 Ws.In contrast with platinum and steel needles, copper needle was non-traumatic to the smooth muscle tissue.

Objective To investigate the nutritional status of iodine among residents and the goiter disease of children in high water iodine areas in Shanxi Province,and to provide a scientific basis for establishment of longlasting control strategies and measures.Methods In 2012,according to the historical monitoring data,in the 10 high water iodine counties (citys,districts),one town was selected based on its location (east,west,south,north and middle) in each county (citie,district).In county (city,district) with 5 townships or less,all townships were selected.Four villages were selected in each township and fifteen residents in each village were selected to test salt iodine level.In five high water iodine counties (city,district),one or two high water iodine villages were selected,water samples were collected and the iodine content was measured; one hundred students aged 8-10 years old were chosen to examine their thyroid size.Thirty children were chosen from above students to collect their urine samples and to determine the iodine content.Results In 10 high water iodine counties (citys,districts),1 680 salt samples were tested.The rate of non-iodized salt was 85.2％ (1 432/1 680); in six villages of five high water iodine counties (citys,districts),the median of urinary iodine of 256 children aged 8 to 10 was 487.2 μg/L; in three villages which had improved the quality of water,the median of urinary iodine was 271.0 μg/L; other three villages which had not improved the quality of water,the median of urinary iodine was 692.6 μg/L.In those villages which had not improved the quality of water,urinary iodine of children ≥300 μg/L accounted for 85.8％ (139/162); in those villages which had improved the quality of water,high urinary iodine of children accounted for 41.5％ (39/94),and the difference was statistically significant (x2 =53.06,P ＜ 0.05).The thyroid was investigated among 591 children aged 8-10 years old,and the goiter rate was 6.6％(39/591).In those villages which had improved the quality of water,the goiter rate of children was 3.8％ (11/291),but in villages which had not improved the quality of water,the goiter rate of children was 9.3％ (28/300),and the difference was statistically significant (x2 =6.52,P ＜ 0.05).Conclusion The iodine nutrition level of residents in high water iodine areas in Shanxi is excessive,children's goiter disease has not been effectively controlled; water improvement to reduce iodine is the basic way to control the disease of high iodine.

Objective To analyze the effect of adjustments of control strategy on epidemic trend of iodine deficiency disorders (IDD) in Shanxi Province after universal salt iodization (USI),and to provide basis for timely adopting targeted control countermeasure and scientifically adjusting intervention strategy.Methods A method of retrospective analysis was performed to collect data from IDD surveillance at national or province levels after 1995,and from iodized salt surveillance of the province after 2004.According to the statistics and analysis of children's goiter rate,median urinary,median and mean of salt iodine,coverage rate of iodized salt,qualified rate of iodized salt,consumption rate of qualified iodized salt and their relationship.Results Since 1995,the children's goiter rate by palpation and B-ultrasound showed a steady descending trend.The median salt iodine,mean salt iodine and children's median urinary iodine showed a trend of rise→decline→stable→decline.Namely:The three indicators began to rise year by year from 1995 (29.1 mg/kg,31.7 ± 15.0 mg/kg,199.3 μg/L),in 1999 (48.7 mg/kg,53.4 ± 29.4 mg/kg,407.5 μg/L) reached its climax; and then decreased,in 2001 (34.7 mg/kg,36.2 ± 11.9 mg/kg,282.1 μg/L)stoped; which were basically stable from 2001 to 2011; since 2013 (26.0 mg/kg,26.5 ± 6.3 mg/kg,192.0 μg/L),a significant decline began.The rate and edible rate of qualified iodized salt showed a trend of decline→rise→stable.Two indexes began to decline circuitously from 1995 (72.61％,68.25％),and dipped to a low point in 1999 (44.80％,43.67％); then began to rise,until 2002 (94.73％,91.80％) reached basic stability; and remained steady from 2002 to 2013.Conclusions Following the process of prevention and treatment of IDD for more than 30 years in Shanxi Province,with the depth understanding of the range of adequate iodine nutrition,according to the monitoringfeedback mechanism,the strategy of salt iodization has been adjusted several times,the target of continuous elimination of IDD has achieved since 2000 and the levels of iodine nutrition in population are more reasonable.Salt iodization strategy should continue to adhere to.

Objective To investigate resident iodine nutrition level in waterborne high iodine areas and prevalence of high iodine goiter in Shanxi Province.Methods In 2014,in Shanxi Province,in all the 10 high iodine counties (cities,districts),the jurisdiction area of each county (city,district) was divided into two blocks,high iodine and not high iodine districts,and in high iodine area of each county (city,area) according to their sub-area positions of east,south,west,north and center,a township was randomly selected (if the number of high iodine area in iodine excessive township ≤5,all townships were selected);four administrative villages in each monitoring township were randomly selected;in each administrative village,the edible salt samples of 15 randomly selected households were collected for detection of iodine content.Five counties (cities,districts) were selected from the province's 10 high iodine counties (cities,districts),water iodine content of 3 counties (cities,districts) was 150-300 μg/L,and 2 were ＞ 300 μg/L,one administrative village was selected from each county (city,area),household drinking water samples were collected to detect iodine content;and 100 elementary school children aged 8-10 were selected from the village where the monitoring stations located in for thyroid volume ultrasound measurement,and 30 of them were randomly selected for urinary iodine content detection.Results ① In the 10 high iodine counties (cities,districts),1 680 households salt samples were detected,and the rate of no iodine salt samples was 89.2％(1 499/1 680).② Fourteen water samples were collected in 5 counties (cities,districts),and the water iodine content was 155.7-467.3 μg/L.③ In the five high iodine counties (cities,districts),197 urine samples were collected from children aged 8 to 10.The median of urinary iodine was 466.5 μg/L;the median urinary iodine was 650.1 μg/L in water iodine≥300 μg/L children group which was significantly higher than that of the group with 150-300 μg/L water iodine content 332.5 μg/L (Z =-6.164,P ＜ 0.05);urinary iodine level of children and the water iodine of the corresponding village was positively correlated (r =0.543,P ＜ 0.05).④ In the five high iodine counties (cities,districts),543 children aged 8-10 were measured with their thyroid volume,the thyroid goiter rate was 6.8％(37/543);the goiter rate of water iodine ≥300 μg/L children group was [9.0％(28/311)] which was significantly higher than that in the iodine content of drinking water 150-300 μg/L group [3.9％(9/232),x2 =5.494,P ＜ 0.05].Conclusion The measurement of stopping iodized salt supply in high iodine areas in Shanxi Province is well implemented,iodine nutrition level and thyroid goiter rate in those areas are still too high,high iodine intervention measures can be focused on changing of the drinking water.

OBJECTIVE: To observe the inhibitive effect of pirenzepine on form deprivation myopia in guinea pigs and to explore the mechanism of Smad3 signaling pathway and connective tissue growth factor (CTGF) in the inhibition of myopia by pirenzepine. METHODS: Forty 1-week-old guinea pigs of either sex were randomly divided into 4 groups: a control group (Group I), a form deprivation group (Group II), a pirenzepine ophthalmic solution group (Group III), and a sodium chloride ophthalmic solution group (Group IV). Translucent blinders were used in the right eyes of Group II, III and IV. The left eyes were not given any treatment as the normal control group. Covered eyes of Group III and IV were given 3% pirenzepine ophthalmic solution and 0.1% azone ophthalmic solution respectively twice every day. Six weeks later, refraction and axial length were measured at the end of the experiment, and immunohistochemistry and Western blot were used to analyze the expression levels of Smad3 and CTGF in the sclera of all 4 groups. RESULTS: There was no significant difference between Group III and I in relative refraction and changes of axial length (P>0.05). The difference of Group II and IV compared with Group I was statistically significant (P<0.05). The number of Smad3 and CTGF positive cells in the sclera between Group III and I was not significantly different (P>0.05), while the difference in Group II, IV and I was significant (P<0.05). Western blot showed that the expression levels of Smad3 and CTGF in Group II and IV were much lower than those in Group I (P<0.05), but not evident in Group III and I (P>0.05). CONCLUSION Pirenzepine ophthalmic solution can inhibit the development of form deprivation myopia. Pirenzepine may affect Smad3 signaling pathway in the sclera by inhibiting the development of form deprivation myopia.

Objective To understand the iodine nutritional status and thyroid function of different populations after 20 years of universal salt iodization in iodine deficiency area of Shanxi Province, and to provide data support for scientific iodine supplementation according to local conditions. Methods In 2014, six townships (Chengguan, Dadeng, Dengzhuang, Gucheng, Xiangling and Fencheng townships) in Xiangfen County, Linfen City, Shanxi Province, were selected as the place of investigation. Four hundred school-age children aged 6 - 12 years (school-age children), 400 child-bearing women aged 18 - 44 (child-bearing women), 400 pregnant women, 400 lactating women and their 0 - 6 months breast-feeding infants (breast-feeding infants), and 400 children aged 7 -24 months were selected by two-stage sampling method. Water samples of school-age children's domestic drinking water and salt samples for domestic consumption were collected, and the water iodine and salt iodine were detected by arsenic and cerium catalytic spectrophotometry ( recommended by the National Iodine Deficiency Disorders Reference Laboratory) and "General Test Method in Salt Industry-Determination of Iodine" (GB/T 13025.7-2012). Random urine samples of all subjects were collected, urine iodine was detected by "Method for Determination of Iodine in Urine by As3+-Ce4+ Catalytic Spectrophotometry" ( WS/T 107-2006 ) . Samples of filter paper dried blood spots (DBS) of school-age children, child-bearing women, pregnant women, lactating women and breast-feeding infants were collected, and serum total thyroxine (TT4) and thyroid stimulating hormone (TSH) levels were detected by time-resolved fluorescence immunoassay. Results A total of 290 water samples were collected, and the median of water iodine was 9.37μg/L. A total of 406 salt samples were collected, the median of salt iodine was 25.0 mg/kg, the coverage rate of iodized salt was 98.52％ (400/406), and the consumption rate of qualified iodized salt was 92.61％ (376/406). Urine samples of 389 school-age children, 379 child-bearing women, 363 pregnant women, 365 lactating women, 366 breast-feeding infants, and 366 children aged 7 - 24 months were collected, and the medians of urine iodine were 200.7, 175.0, 186.0, 113.2, 285.8 and 204.8 μg/L, respectively. Among them, school-age children, breast-feeding infants, and children aged 7-24 months were over the appropriate level, while the rest populations were at the iodine appropriate levels. Blood samples of 402 school-age children, 397 child-bearing women, 398 pregnant women, 390 lactating women, and 386 breast-feeding infants were collected, and the medians of TT4 were 127.2, 110.2, 141.7, 95.8 and 139.0 nmol/L, respectively; the medians of TSH were 1.2, 0.9, 0.8, 0.9 and 0.9 mU/L, respectively, and they were all within the reference ranges. The abnormal rates of TT4 (8.46％, 33/390) and TSH (7.95％, 31/390) in lactating women were higher than those in school-age children, child-bearing women, pregnant women and breast-feeding infants [TT4 abnormal rates were 0.25％(1/402), 1.26％ (5/397), 0.50％ (2/398), 1.04％ (4/386), respectively; TSH abnormal rates were 1.24％ (5/402), 1.51％ (6/397), 1.51％ (6/398) and 0.78％ (3/386), respectively, P < 0.05]. The rate of thyroid dysfunction in lactating women (7.95％, 31/390) was higher than those in the rest populations [1.24％ (5/402), 1.51％ (6/397), 1.51％ (6/398), 0.78％ (3/386), P < 0.05]. Conclusions The iodine intake of different populations in the survey area is generally sufficient, and the current salt iodine content standard can meet the iodine nutrition needs of different populations. Lactating women have a high rate of thyroid dysfunction. It is suggested to stick to the strategy of universal salt iodization to prevent iodine deficiency hazards in iodine deficiency areas, and further strengthen the monitoring of iodine nutrition and thyroid function of pregnant women and lactating women.
