Objective To understand the current situation of iodine deficient disorder(IDD) 10 years after achieving the stage goal of eliminating IDD in Longyan city and to evaluate the effect of prevention and treatment measures, and to provide the basis for the development of control strategies. Methods There were 7 counties in the city, and each county(city, district) was as a unit to carry out the inspection for organization and leadership,iodine salt management, monitoring and control, health education (referred to as the four management indicators)according to "The County-Level Assessment and Evaluation Implementation Detailed Rules of Realizing the Goal to Eliminate IDD in Fujian Province". According to the east, west, south, north and middle positions in each county,a village and a primary school were selected. Forty 8 to 10 year-old students in each school were randomly selected to check thyroid and among them 20 students were collected urine samples to determine urinary iodine. Nine townships were selected in the 7 counties of the city and among which 4 administrative villages were selected in each township. Eight edible salt samples from each household in each administrative village were collected to test salt iodine. Goiter was examined by palpation, the level of urinary iodine was examined by arsenic and cerium spectrophotometry, salt iodine was detected by direct titration. Results The average score of the four management indicators was 94.1 in Longyan city. The adjusted goiter rate of children aged 8 - 10 years old was 1.9%. The median of urinary iodine was 278.6 μg/L, among which less than 100 μg/L accounted for 4.57%(32/700), 100 -< 200 μg/L accounted for 24.00%(168/700), 200 - < 300 μg/L accounted for 25.29%(177/700), and higher than 300 μg/L accounted for 46.14%(323/700). The using rate of qualified iodized salt was 98.86%. The coverage rate of iodized salt was 99.50%, the qualified rate of iodized salt was 99.35%, and the rate of non-iodized salt was 0.50%. All the indicators had reached the national standard to eliminate IDD. Conclusions After achieving the stage goal of eliminating IDD, the disease is stable and the effect of control measures are significantly. But the iodine provided has a trend of more than suitable. Therefore, it is reasonable to reduce the current salt iodine content.

OBJECTIVETo investigate whether the alterations of microtubule and microfilament expression are responsible for the neurotoxicity of carbon disulfide.
METHODSWistar rats were administered with carbon disulfide by gavage at a dosage of 300 or 500 mg/kg for continuous 12 weeks (five times per week). Spinal cords of carbon disulfide-intoxicated rats and their age-matched controls were Triton-extracted and ultracentrifuged to yield a pellet and a corresponding supernatant fraction. Then, the contents of alpha-tubulin, beta-tubulin, and beta-actin in both fractions were determined by immunoblotting. In the meantime, their mRNA levels in spinal cords were quantified using reverse transcriptase-polymerase chain reaction (RT-PCR).
RESULTSIn the supernatant fraction, the contents of beta-tubulin and beta-actin in both treated groups increased significantly (P < 0.01) the content of beta-tubulin increased by 141% and 158% respectively, and the content of beta-actin increased by 19% and 32% respectively. In the pellet fraction, the content of beta-tubulin in both groups increased by 107%(P < 0.01) and 118%(P < 0.01) respectively, and the others keep unaffected. In the meantime, the levels of of mRNA expression of beta-tubulin and beta-actin gene were elevated consistently in CS(2)-treated groups (P < 0.01) the levels of mRNA expression of beta-tubulin increased by 207% and 212% respectively, and the levels of mRNA expression of beta-actin increased by 94% and 91% respectively.
CONCLUSIONCarbon disulfide intoxication results in alternations of microtubule and microfilament expression, and the alternations might be related to its neurotoxicity.

This study is to elucidate the metabolic pathway of 1,2-[bis (1,2-benzisoselenazolone-3 (2H)-ketone)]-ethane (BBSKE) in rats. Rats were administrated with a single dose of BBSKE 200 mg x kg(-1). The metabolites in rat urine, feces, bile and plasma were identified by LC-MSn analysis. The characterization of fragment ions from LC-MSn chromatography and mass spectrometry was applied to the investigation of structures of metabolites. Three phase I metabolites were detected in rat urine and feces. Two of them were also found in plasma and one existed in bile. These products were derived from oxidized, methylated and S-methylated BBSKE, separately. One phase II glucuronide of BBSKE was also found in bile. Therefore, it is possible that BBSKE was metabolized by oxidization, methylation and glucuronidation.

Comparative analysis of variable region ORF14/15 genes of white spot syndrome virus (WSSV) genome in Guangxi Penaeus vannamei (P. vannamei) could provide useful information for the evaluation of genetic diversity and genetic evolutionary relationship among WSSV isolates from Guangxi, China and other places. Based on geographical and temporal considerations, 40 WSSV-positive P. vannamei samples were collected during the period between May 2010 and July 2013 from Beihai, Qinzhou, and Fangchenggang, which were the main P. vannamei production areas in Guangxi, and the variable region ORF14/15 genes of the WSSV genome from all infected samples were amplified by PCR and then subjected to cloning and sequence analysis. Pairwise and multiple alignment analysis was then conducted to evaluate the degree of genetic divergence between different strains. The variable region ORF14/15 genes from 25 of 40 WSSV positive samples were successfully cloned and sequenced; among the ORF14/15 genes of 25 WSSV-positive strains, 22 was 619 bp in length and 3 was 620 bp. All the 25 Guangxi strains carried a 5949-bp deletion in the ORF14/15 region relative to TH-96-II, which has the longest nucleotide sequence in this region; the deletion of Guangxi strains occurred in the middle region of ORF14/15 gene, with only 190 bp and 429 bp/ 430 bp at 5' and 3' ends, respectively, which were coincident with WSSV-IN-05-I in deletion length and position. Sixteen of 25 Guangxi strains had completely identical nucleotide sequences in the variable re gion, and the homology between other strains also exceeded 97.9%. There were single nucleotide substi tution, deletion, and insertion in the ORF14/15 region of Guangxi strains compared with other strains in GenBank. In the phylogenetic tree based on WSSV variable region ORF14/15, the Guangxi strains were closely related and formed a separate branch with Indian strain IN-05-I, but far from other strains in GenBank. The ORF14/15 gene of WSSV isolates in cultured P. vannamei in Guangxi has a large deletion in the middle of the variable region, and the Guangxi WSSV strains show no significant spatio-temporal differences; the Guangxi strains are closer in genetics to Indian strain IN-05-I than other strains in GenBank.
