Objective To learn the status of iodine nutrition and the goiter of children and pregnant woman in Zhejiang Province after the iodine salt concentration adjustment.Methods The proportionate to population size sampling was applied to select 30 surveillance areas in Zhejiang Province,and iodine nutritional status were evaluated by 4 indicators that include goiter rate in 8 -10 years old children,urine iodine,iodized salt and water iodine.Results The iodine content of 1 565 edible salt samples collected from the above children was measured,and the iodine median(P25 -P75 )was 23.30 (21.00 -25.80)mg/kg.The coverage of iodized salt rate was 88.43%,and 95.88% iodized salts was qualified.The qualified iodized -salt ingesting rate was 84.79%.The iodine content of children aged 8 -10 years old and pregnant woman was tested,and iodine median (P25 -P75 )was 171.99 (113.00 -243.89 ),134.14 (82.10 -202.98)g/L respectively.The iodine content of 66 water samples were randomly collected from the surveillance areas to be tested,and iodine median(P25 -P75 )was 2.42(1.17 -6.28)μg/L.The proportion less than 10 g/L was 87.9%.The goiter status of 1 565 children were examined by B -type of ultrasonic,and the prevalence of goiter was 4.98%.Conclusion After the iodine salt concentration adjustment,the status of iodine nutrition in children was in optimum level,but the level of iodine nutrition in pregnant women was less than the state,which should be paid more attention.

Objective To evaluate the dietary iodine intake level of population in coastal and inland areas of Zhejiang province.Methods The cluster sampling method was applied to select Zhoushan,Ningbo and Taizhou cities from Zhejiang province as coastal areas,to select Jinhua,Quzhou and Lishui cities from Zhejiang province as inland areas,and two counties(districts) were randomly selected in each chosen city,three sub-districts(towns) were randomly selected in each chosen counties (districts),then one community (village) was randomly selected in each chosen sub-districts(towns).Adult residents aged greater than 18 were selected as investigation subjects,their dietary iodine intake in the past 24 hours was investigated,and the Food composition table” was inquired to get the data of dietary iodine intake.One hundred copies of residential edible salt samples and drinking water samples in each of the selected community (village) were collected to detect salt iodine and water iodine by direct titrimetric and spectrophotometric method,respectively.Results The mean of adult residents' dietary iodine intake in Zhejiang coastal area was 267.76 μg/d,which was less than that in inland area (429.05 μg/d,t =- 6.90,P ＜0.05),and the means of adult residents' dietary iodine intake from drinking water,laver and fish(5.75,69.72,5.61 μg/d,respectively) in coastal area were higher than those in inland areas(3.25,35.27,3.43 μg/d,respectively,t =21.73,3.92,4.08,all P ＜ 0.05),however,the means of adult residents' dietary iodine intake from salt,kelp and other food (166.81,3.04,16.82 μg/d,respectively) in coastal areas were less than those in inland areas (355.15,6.14,25.81 μg/d,respectively,t =- 8.76,- 5.49,- 18.56,all P ＜ 0.05).In coastal areas,the proportion which was less than estimated average requirement of iodine(EAR,120 μg/d) was 46.48％ (1029/2214),the ratio which was higher than the maximum tolerable intake of iodine(UL,1000 μg/d) was 3.34％ (74/2214),and the average contribution rate of dietary intake of iodine in salt was 62.30％(166.81/267.76).While in inland areas,the corresponding proportions were 7.61％ (171/2246),2.80％ (63/2246) and 82.78％ (355.15/429.05),respectively.Conclusions The dietary iodine intake in Zhejiang inland areas has reached the recommended nutrient intake levels of the Chinese Nutrition Society,but there is a certain degree of insufficient iodine intake in population of the coastal areas.

BACKGROUNDCardiovascular diseases, especially coronary artery disease (CAD), are major causes of death in industrialized countries. Elevated concentrations of plasma homocysteine (Hcy) have been associated with an increased risk of CAD. Increased plasma levels of chemokine, characterized by their ability to induce migration and activation of leukocytes, may contribute to the pathogenesis of CAD. This study was designed to investigate the changes of plasma Hcy, monocyte chemoattractant protein-1 (MCP-1) and oxidative stress markers in acute coronary syndrome patients.

METHODSA total of 149 subjects were divided into four groups: 50 patients with unstable angina, 30 patients with acute myocardial infarction, 20 coronary restenosis patients after percutaneous coronary intervention and 49 healthy control subjects. Plasma levels of Hcy, MCP-1, malondialdehyde and superoxide dismutase were measured.

RESULTSPlasma levels of Hcy and MCP-1 showed significant increases in unstable angina, acute myocardial infarction and restenosis patients compared with control subjects (P < 0.05, respectively). Plasma levels of malondialdehyde were significantly increased in unstable angina and acute myocardial infarction patients when compared with control subjects (P < 0.05, respectively). Plasma superoxide dismutase levels were significantly reduced in acute myocardial infarction patients when compared with control group (P < 0.01).

CONCLUSIONHcy might act as an atherogenic factor through promoting chemokine, reactive oxygen species and oxidized low density lipoprotein production and thereby convert a stable plaque into an unstable potentially occlusive lesion.

OBJECTIVETo investigate the effect of folic acid on homocysteine (Hcy)-induced chemokine secretion and NADPH oxidase activity in human monocytes.

METHODSHuman monocytes from healthy volunteers were incubated with Hcy (100 micromol/L) with or without folic acid (5 micromol/L) for 24 h; MCP-1 and IL-8 were assessed by ELISA. DCFH-DA was added to monitor intracellular ROS production on confocal microscopy. A cytochrome c reduction assay was used to measure NADPH oxidase activity.

RESULTSThe Hcy-induced secretion of MCP-1 and IL-8 was significantly reduced by folic acid [(1.88 +/- 0.51) ng/ml vs. (4.36 +/- 0.72) ng/ml vs. (2.40 +/- 0.60) ng/ml and (4.9 +/- 1.9) ng/ml vs. (12.7 +/- 1.5) ng/ml vs. (7.2 +/- 1.9) ng/ml, all P < 0.05]. The Hcy-induced production of ROS was also significantly attenuated by folic acid. Moreover, the Hcy-induced NADPH oxidase activity increase was significantly inhibited by cotreatment with folic acid.

CONCLUSIONFolic acid may attenuate oxidative stress induced by Hcy by reducing NADPH oxidase activity in monocytes.

OBJECTIVETo study the related factors of right recurrent nerve nodal involvement in esophageal cancer.

METHODS280 patients with thoracic esophageal cancer received esophagectomy and right recurrent nerve node dissection. The clinicopathological data were analyzed retrospectively. Univariate data were analyzed by chi-square test, and multivariate data were analyzed by logistic regression.

RESULTSThe right recurrent nerve nodal metastasis was found in 76 cases (27.1%, 76/280). In the 979 excised right recurrent nerve nodes, metastases were found in 118 nodes (12.1%). The tumor staging, the total number of involved lymph nodes, vascular invasion, the number of lymph node metastases in the thorax, the number of lymph node metastasis in the abdomen, subcarinal node metastasis, and peri-esophageal lymph node metastasis were independent risk factors of right recurrent nerve node metastasis in esophageal carcinoma.

CONCLUSIONRight recurrent nerve lymph nodes should be dissected in those patients with high risk factors of lymph node metastasis in thoracic esophageal carcinoma.
