Objective: To investigate the iodine nutrition status of children in water borne iodine excess areas in Hebei Province, so as to provide references for scientific prevention and control of water borne iodine excess hazards. Methods: From March to September each year during 2018 to 2023, a cross sectional survey was conducted in 39 water borne iodine excess counties (measured in 2017) from 5 cities (Cangzhou, Hengshui, Xingtai, Handan and Langfang) in Hebei Province. The survey included the detection of iodine content in residents drinking water, the measurement of thyroid volume in children aged 6-12, the detection of salt iodine and urinary iodine. The iodine nutrition status and water iodine distribution of 6-12 year-old children were evaluated from different perspectives such as years, gender, and age. Kruskal-Wallis H- test, Mann-Whitney U test and Chi square test were used for group comparison. Results: A total of 38 755 children were surveyed from 2018 to 2023, and 1 270 drinking water samples were tested across the province. The mass volume concentration of iodine in water showed a decreasing trend over the years ( Z= -30.87, P <0.01). Among 38 470 salt samples monitored from children s home, 24 790 were not non iodized salt, with a non iodized salt rate of 64.44%. A total of 31 989 urine samples were collected from children aged 8-10 years, with the median urine iodine was 245.94 μg/L. Comparing the results of urinary iodine in children from different years, the median urinary iodine from 2018 to 2023 were 328.0, 339.3, 267.8, 279.1, 291.3, 186.5 μg/L, respectively, with statistically significant differences ( H= 4 138.40 , P <0.01). Further pairwise comparisons showed that the median urinary iodine of children in 2023 was lower than in all other years ( Z =-51.59 to -11.41, all P <0.01). Among children aged 6-12 years, 1 150 cases of goiter were detected and the rate of goiter was 3.0%; and the goiter rates in boys and girls were 2.8% and 3.1%, with no significant difference between the sexes ( χ 2= 2.76, P >0.05). There were significant differences in the rate of goiter among different years and ages ( χ 2=324.02, 191.61, both P <0.05). Conclusions With the progress of water reform in water borne iodine excess areas of Hebei Province, children s iodine nutrition has reduced from excessive state to suitable state. It is necessary to continue to expand the coverage of water based iodine reduction projects, and strengthen the monitoring of iodine nutrition status of key populations in water borne iodine excess areas.

Objective:To dynamically investigate the iodine nutritional status of residents in water source high iodine areas in Hebei Province, so as to provide basis for taking targeted prevention and control measures and accurate intervention strategies.Methods:According to the "National Monitoring Program for Water Source High Iodine Areas (2018 Edition)", water source high iodine monitoring was carried out in 5 cities and 35 counties (cities, districts, hereinafter referred to as counties) of Hebei Province. According to the survey results of drinking water iodine of residents of Hebei Province in 2017, the administrative villages with a median water iodine above 100 μg/L were sorted according to the water iodine value. The systematic sampling method was adopted. Five administrative villages were selected in each county, if there were less than 5 administrative villages, all of them were selected (if the median water iodine was > 300 μg/L, at least one village shall be selected). The iodine content in drinking water of residents among the monitoring sites, salt iodine, urinary iodine and thyroid volume of children aged 8 - 10, as well as salt iodine and urinary iodine of pregnant women were tested. Water iodine was detected by the "Method Suitable for the Detection of Water Iodine in Iodine Deficient and High Iodine Areas" recommended by the National Iodine Deficiency Reference Laboratory of the Chinese Center for Disease Control and Prevention. Salt iodine was detected by semi quantitative method. Urinary iodine was detected by "Arsenic Cerium Catalytic Spectrophotometry Method" (WS/T 107-2006). Children's thyroid volume was detected by B-ultrasound.Results:A total of 239 water samples were collected in 167 villages, 35 counties, the median water iodine was 163.95 μg/L, ranging from 5.53 - 930.82 μg/L. A total of 6 772 edible salt samples were monitored, including 3 495 non-iodine salt samples and the rate of non-iodine salt was 51.61% (3 495/6 772). A total of 6 101 urine samples of children were tested, the median urinary iodine was 328.00 μg/L. A total of 6 103 children aged 8 - 10 were carried out B-ultrasound detection of thyroid volume in 35 counties. The goiter rate of children was 5.01% (306/6 103), and the rate of nodules was 0.56% (34/6 103). A total of 713 urine samples of pregnant women were tested, and the median urinary iodine was 221.70 μg/L.Conclusions:The iodine nutrition of children in water source high iodine areas of Hebei Province is at an excess level, and the iodine nutrition of pregnant women is at an appropriate level. In addition to stopping the supply of iodized salt, we should further expand the coverage of water improvement and iodine reduction projects in high iodine areas, and strengthen the monitoring of iodine nutrition status of key populations.

Objective:To master the iodine nutritional level of children aged 8-10 and pregnant women in non-iodine excess areas in Hebei Province, and provide scientific basis and targeted prevention and treatment strategies for prevention and treatment of iodine deficiency disorders.Methods:Iodine nutrition analysis was conducted in 162 counties (cities and districts, hereinafter referred to as counties) of Hebei Province in 2018. Each monitoring county was divided into 5 sampling areas according to east, west, south, north and middle locations. One township/street was randomly selected in each area, 1 primary school was selected in each township/street, and 40 non-boarding students aged 8-10 were selected from each primary school. In each monitoring county, 20 pregnant women were selected from each of the 5 townships/streets. Both children and pregnant women were collected samples for salt and urinary iodine (with a random urine sample) detection. The iodine content of salt was tested using the "General Test Method for Salt Industry-Determination of Iodine" (GB/T 13025.7-2012), and Sichuan salt and other fortified edible salt used the arbitration method. The urinary iodine content was tested using the "Arsenic-Cerium Catalytic Spectrophotometric Determination of Iodine in Urine" (WS/T 107-2006).Results:A total of 31 883 samples of edible salt were collected from children's homes in 162 counties, among which 28 539 were iodized salt, 26 456 were qualified iodized salt, the iodized salt coverage rate was 88.36% (after population standardization), and the qualified iodized salt consumption rate was 81.03% (after population standardization). A total of 31 883 urine samples were collected from children, with the median urinary iodine of 193.13 μg/L. There was one county with a median urinary iodine < 100 μg/L, and the median urinary iodine in 150 counties was 100-299 μg/L. A total of 15 572 salt samples of pregnant women were collected, among which the iodized salt samples were 14 260, the qualified iodized salt samples were 13 363, the iodized salt coverage rate was 90.10% (after population standardization), and the qualified iodized salt consumption rate was 83.54% (after population standardization). A total of 15 569 pregnant women were collected urine samples, the median urinary iodine was 164.86 μg/L, and the number of counties with a median urinary iodine < 150 μg/L was 67.Conclusions:Iodine nutrition of children and pregnant women is appropriate at the provincial level, but children and pregnant women in some counties are at risk of iodine deficiency. In the future, the prevention and treatment of iodine deficiency disorders should focus on the iodine nutrition monitoring of the special needs.

Objective:To explore the application effect of Jiankuai psychosomatic active therapy in the elderly perioperative patients.Methods:From March 2018 to December 2019, 387 elderly patients in the urology department of the First People′s Hospital of Lianyungang City, Jiangsu Province were selected. According to the patients in two medical groups in the same ward, 193 patients in one medical group were divided into the experimental group and 194 patients in two medical groups as the control group. The experimental group was intervened by routine perioperative nursing combined with simple and fast psychosomatic active therapy, while the control group was only intervened by routine perioperative nursing. Self rating Anxiety Scale (SAS), Rosenberg Self-confidence Scale and General Self-efficacy Scale (GSEs) were used as the evaluation indexes before and after the implementation of the two groups.Results:The SAS score of the experimental group was 31.13 ± 3.64 and that of the control group was 48.45 ± 7.72 on the 7th day after operation. The difference between the two groups was statistically significant ( t value was 16.36, P < 0.05). The effective rate of self-confidence was 98.4% (190/193) and 94.8% (183/193) in the experimental group and 86.6% (168/194) and 85.1% (165/194) in the control group on the first day and the seventh day after operation, respectively. The difference between the two groups was statistically significant ( Z values were - 3.27 and 14.66, all P < 0.05). The GSEs score of the patients in the experimental group was 26.79 ± 2.17 and that of the control group was 16.86 ± 1.90. The difference between the two groups was statistically significant ( t value was 10.19, P < 0.05). Conclusions:The application of Jiankuai psychosomatic active therapy can effectively reduce the tension and anxiety of the elderly patients during the perioperative period, increase their self-confidence and self-efficacy, effectively improve the communication efficiency between doctors and patients, and promote rehabilitation.

The number of villages with median of water iodine ≥300 μg/L was 1 577 (8.80%). The water-borne high iodine areas in Hebei Province were distributed in 39 counties (cities, districts) of five cities, namely, Cangzhou, Handan, Xingtai, Hengshui and Langfang. They were mainly distributed in sheet shape or spot shape.Conclusion:The water-borne high iodine areas in Hebei Province are widely distributed, in the form of sheet or spot.

Objective To evaluate the results of external quality assessment (EQA) of iodine deficiency disorders laboratories and the network operation in Hebei Province in 2017 in order to further improve the quality of EQA and provide reliable laboratory quality assurance for epidemiological surveillance and control of iodine deficiency disorders. Methods The EQA of salt iodine, water iodine and urinary iodine of iodine deficiency disorders laboratories at provincial, prefectural and county levels in Hebei Province in 2017 was evaluated. Among them, there were 1 provincial, 11 prefectural, and 128 county-level laboratories participated in the national urinary iodine assessment; there were 1 provincial and 11 prefectural-level laboratories participated in the national water iodine assessment; 1 provincial, 11 prefectural, and 30 county-level laboratories participated in the national salt iodine assessment;and 138 county-level laboratories participated in the provincial-level salt iodine assessment. The testing results of water iodine and urinary iodine of all the participatory laboratories were evaluated by using standard Z score generated from laboratories participated in the examination. The testing results of salt iodine were evaluated by using reference value ± uncertainty. Results One provincial and 11 prefectural-level iodine deficiency disorders laboratories in Hebei Province participated in the national urinary iodine, water iodine and salt iodine assessment, the qualified rate was 100.0％(12/12);128 county-level iodine deficiency disorders laboratories participated in the national urinary iodine assessment, the qualified rate was 100.0％(128/128);30 county-level iodine deficiency disorders laboratories took part in the national salt iodine assessment, the qualified rate was 100.0％(30/30);and 138 county-level iodine deficiency disorders laboratories participated in the provincial-level salt iodine assessment, the qualified rate was 94.9％(131/138). Conclusions Iodine deficiency disorders laboratories in Hebei Province in 2017 have remained at a relatively high level in detection quality, and network operation is good. Only a few county-level laboratories failed to pass the examination. Therefore, the key task in the future is to strengthen the detection capacity of county-level laboratories.

Objective: To evaluate the post-operative mortality of left ventricular end-diastolic pressure (LVEDP) during primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: We retrospectively analyzed 255 patients with new onset of STEMI who received primary PCI in our hospital and all patients received LVEDP measurement before coronary artery opening. According to LVEDP value, the patients were divided into 2 groups: LVEDP≤14 mmHg group,n=155 and LVEDP>14 mmHg group,n=100. The post-operative mortality up to 6 months was observed, and the effect of LVEDP on death rate was studied by Cox regression analysis. Results: Compared with LVEDP≤14 mmHg group, the patients in LVEDP>14 mmHg group had the 6 months mortality at HR=4.26, 95% CI (1.13-16.08),P=0.03. Relevant study presented that LVEDP was slightly related to LVEF (r=-0.267, P=0.001) and BNP (r=-0.154,P=0.041). Multi-regression analysis indicated that with adjusted LVEF and BNP, LVEDP was the independent predictor for post-operative mortality up to 6 months in acute STEMI patients after PCI. Conclusion: The LVEDP value measured during PCI procedure is the independent predictor for mortality after PCI in patients with new onset of STEMI.

Objective To evaluate the outcome of ST-segment elevation myocardial infarction (STEMI) patients received different reperfusion therapies. Methods The 238 consecutive STEMI patients were enrolled from February 2012 to December 2012. According to the current guideline of PCI and the choice of patients, the patients were divided into the groups of percutaneous coronary intervention (PCI), ifbrinolysis, and conservative medication. The major adverse cardiac events (MACE) was analyzed in a follow up of 6 months. Results (1) The enrolled patients included the 210 patients received PCI (88.2%), 14 patients received fibrinolysis (5.9%) and 14 patients received conservative medication (5.9%).The Median time of D2B was 110minutes.(2) The rate of late stent thrombosis was signiifcant higher in BMS than DES (n=2, 2.8%vs 0, P < 0.05) . (3) The PCI group had a signiifcantly higher incidence of stroke than the ifbrinolysis group and the conservative medication group (1.0%vs 0, P < 0.05;1.0%vs 0, P<0.05). (4) The PCI group had a signiifcantly higher incidence of bleeding compared to the thrombolysis group and the medication group (1.0% vs 0, P < 0.05; 1.0% vs 0%, P < 0.05). Conclusions The majority of STEMI patients received PCI;The D2B time, which was required<90 minutes in guideline of PCI, was found delayed in our study;Compared to ifbrinolysis and conservative medication, PCI showed better clinical outcomes of STEMI patients.
