Reverse transcriptase-PCR experiments suggest that the two clusters of genes potentially involved in the oxidation of reduced sulfur compounds are organized as operons in strain of the acidophilic, chemolithoautotrophic bacterium Acidithiobacillus ferrooxidans ATCC 23270, the two clusters of genes including such the ORF of putative sulfate-thiosulfate-molybdate binding proteins, the ORF of putative thiosulfate: quinone oxidoreductase and the ORF of the rhodanese-like protein (P21). Bioinformatic analyses have predicted the possible promoters sequences and the possible +1 start site of transcription for the doxDA operons.

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.

And various countries make a lot work about mechanism research of acupuncture effect, showing the feature of large range.

Objective To survey and analyze characteristics of brucellosis epidemic in Weinan city of Shaanxi province for the purpose of setting up prevention and control measures for the disease. Methods According to "The Executing Plan for the Work of Surveying Brucellosis Disease in Shaanxi Province", 35 villages(towns) of designated monitoring locations and 24 villages (towns) of randomized monitoring locations in five countries of Weinan were chosen to survey brucellosis disease. The five countries were Chengcheng, Dali, Heyang, Tongguan and Hancheng. High risk populations with a history of contacting livestock and livestock products aged between 7 and 60 underwent clinical and serology examination[rose bengal plate agglutination test(RBPT) and standard tube agglutination test(SAT)]. All manipulation methods and judging standards were in accord with the "Diagnostic Standard for Brucellosis" (WS 269-2007). Results In the designated monitoring location, a total of 8664 people at high risk were investigated, among whom 1407 people were tested by RBPT test and 27 people were positive,the positive rate was 1.92%(27/1407); 27 people were tested by SAT test and 27 people were positive, the positive rate was 100% (27/27); 25 people were diagnosed and the diagnosis rate was 92.59%(25/27). In the randomized monitoring location, a total of 3464 people at high risk were investigated, among whom 411 people were tested by RBPT test and 3 people were positive, the positive rate was 0.73%(3/411 ), 3 people were tested by SAT test which were all positive and made a definite diagnosis. Twenty-eight new cases were made a definite diagnosis and its incidence was 2.06 in a hundred thousand(28/1 361 618). Conclusions The infection of human brucellosis in Weinan city stays at higher level. The governments should increase input for the monitoring,investigating and disinfecting to prevent the disease from increasing and outspreading.

OBJECTIVEThe experiments were conducted to study specialty of seed germinating, plant growing and developing and cultural practices of A. edgeworthii.

METHODThe germinating and sowing test, growth habitants, photosensitive reaction of seedling from subterraneous seeds and above ground seeds on A. edgeworthii were studied in this experiment.

RESULT AND CONCLUSIONThe results indicated that (1) The water could not be absorbed by seed from plant above ground; (2) The underground and above ground seeds could normally germinate, grow, blossom and bear fruits, A. edgeworthii sowed in early May, blossomed in early September and matured in the last ten days of October; (3) The seed leaf of seedling grew underground; (4) The underground seed was produced from subterraneous branch stem which developed from node of seed leaf; (5) A. edgeworthii was shade demanding, high-temperature sensible short-day light plant. The flowering could be greatly advantaged by short-day light treatment (12, 10, 8, 6 h). Cultural practices were studied also in this experiment.

MTT analysis and intracellular calcium measurement by using confocal laser scanning microscopy were used to study the possible mechanism of protective effect of pituitary adenylate cyclase activating polypeptide 27 (PACAP27) from beta amyloid protein (Abeta)-induced neurotoxicity. The results showed that treatment with PACAP (less than 0.1 micromol/L) increased the survival and reproductive ability of neuro-2a cells and protected the neuro-2a cells from being injured by Abeta. The protective effect of PACAP27 was reversed by the competitive PACAP receptor antagonist PACAP6-27. An increase in intracellular calcium was observed when the cells were challenged with Abeta and PACAP. But the calcium increase induced by Abeta kept stable for a long time while PACAP caused a transient rise in intracellular calcium. The intracellular calcium increase induced by Abeta was blocked by pretreatment with PACAP for 10 min. It is suggested that the neuroprotective effect of PACAP against neuronal damage induced by Abeta may result from its role in inhibiting the sustained rise in intracellular calcium.

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.
