The study was conducted to characterize the pharmacokinetics, distribution, metabolism and excretion of CHMFL-FLT3-122 after a single oral dose of 50 mg·kg-1 [14C] labeled CHMFL-FLT3-122 in rats. Isotope tracing techniques were used to analyze drug concentration and identify the distribution of drugs in tissues and metabolites in biological samples. The experiments were approved by the Animal Ethics Committee of XenoBiotic Laboratories-China, Inc. The absolute bioavailability in male and female rats were 45.83% and 50.92% respectively. The parent drug and its metabolites were extensively distributed in the stomach, intestine, liver and lung, and were eliminated completely in 48 h. The majority of radioactivity was excreted through the feces at 92.34% of the dose with a small fraction through urine at 3.99% of the dose. The parent drug was the most significant circulating component, representing 49.23% and 70.65% over the 0-48 h collection time interval in the plasma of male and female. Two major metabolites, M553 (sulfate conjugate) and M457 (N-dealkyl product), were identified in plasma. Metabolites of CHMFL-FLT3-122, including ten phase I and four phase II metabolites, were identified. The metabolic pathways of CHMFL-FLT3-122 were proposed as N-dealkylation, oxidation, amide hydrolysis, sulfate conjugation, and glucuronic conjugation.

Objective To investigate the iodine nutritional status of school children, lactating women and infants in iodine deficient areas of Baicheng and Wushi Counties in Xinjiang Autonomous Region. Methods According to the geographic location of east, south, west and north of county, 10 primary schools of 8 townships were selected. In each school, 10 children among each gender and age group from 8 to 10 years old were selected. A total of 300 school children were chosen. One hundred and four infants aged 0-2 years old and their mother were selected in 8 townships. Iodine content in edible salt at household level, the urinary iodine in school children and lactating women, total goiter rate(TGR) and the status of the intelligence quotient (1Q) of school children, the status of psychological development of infants were observed. Direct titration assay for testing the salt iodine, colorimetric ceric-arsenic assay and vitriolic ammonium assimilation were used for testing urinary iodine. The size of thyroid gland was measured by palpation. The Combined Raven Test for Chinese Rural was used to test the IQ. The psychological development of infants was tested by Danver Development Screening Test (DDST). Results The coverage rate of iodized salt at household level was 73.1% (123/182), however, the proportion of households using adequately iodized salt was 64.1% (118/182). The medium of urinary iodine in school children was 103.7 μ/L, with 47.8%(75/157) less than 100 μg/L and 28.0% (44/157) less than 50 μg/L; it was 123.0 μg/L in Baieheng County, with 44.4%(28/63) less than 100 μg/L and 33.3%(21/63) less than 50 μg/L; it was 100.3 μg/L in Wushi County, 50.0%(47/94) less than 100 μg/L and 24.5%(23/94) less than 50 μg/L. The medium of urinary iodine in locating women was 143.3 μg/L, it was 119.7 μg/L and 184.6 μg/L in Baicheng and Wushi Counties, respectively. The total rate of goiter in school children was 14.3%(43/300), it was 10.8%(13/120) and 16.6%(30/180) in Baicheng and Wushi Counties, respectively. The average IQ in school children was 80.6±11.6, it was 83.0±11.6 and 79.0±11.7 in Baicheng and Wushi Counties, respectively. The proportion of mental retardation in school children (IQ≤69) was 13.0% (39/300), it was 6.7% (8/120) and 17.2%(31/180) in Baicheng and Wushi Counties, respectively. In addition, the proportion of psychological development in infants being normal, suspicious and abnormal was 78.8%(82/104), 12.5% (13/104) and 8.7%(9/104), respectively. Conclusion This study confirms the fact that there is also existence of mental retardation in children and infants, caused by iodine deficiency.

Objective To understand iodine and iron nutritional status of lactating women in Aksu Prefecture of Xinjing Autonomous Region, and to provide proper intervention in control of iodine deficiency disorders (IDD) combined with iron deficiency. Methods Four townships as survey points were selected in Baicheng County of Aksu, where severe iodine deficiency was confirmed, 30 to 40 lactating women were investigated for this study in each townships. Samples of urine and drinking water from their family were collected, and then the iodine concentrations were determined. Whole blood was collected by venipuncture for determinations on serum ferritin (SF), serum iron (SI), total-iron-binding capacity(TIBC), and their thyroid function, including FT3, FT4, TSH. Results Median urinary iodine concentration in 137 lactating women was 134.99 μg/L, however, median urinary iodine in lactating women in Daqiao (99.73 μg/L), Tuokexun(44.17 μg/L) of 4 townships was below 100 μg/L. The proportion of urinary iodine below 50 μg/L was higher than 20% in Chaerqi [21.1% (8/38)], Daqiao [21.4% (6/28)], Tuokexun [47.8% (11/25)]. The medium of iodine concentration in drinking water, that was collected from 78 resident families, was 2.15 μg/L. Lactating women of serum SF, SI, FT4, that lower than the normal value, was accounted for 47.6% (59/124), 16.9%(21/124), 11.8% (15/127)respectively. Lactating women of serum TIBC, TSH, that higher than the normal value, was accounted for 20.2% (25/124),10.2% (13/127). Conclusion There is existence in of the combination severe iodine and iron deficiency in a historical serious IDD endemic area in Aksu Prefecture of Xinjiang Autonomous Region, and iron deficiency may be another important environmental factor for the deterioration of IDD prevalence.

To utilize Pichia pastoris to produce S-adenosyl-L-methionine (SAM), an intracellular expression vector harboring S. cerevisiae SAM2 was transformed into GS115. A recombinant strain having 2 copies of expression cassette was obtained through G418 resistance screening. This strain had higher SAM synthetase activity and higher SAM production capacity than the original strain, when cultured in medium containing methanol and methionine. The carbon source and nitrogen source of medium was optimized. The results showed SAM production by this strain was closely related to carbon metabolism. With supplementation of 0.2% glycerol every day from the beginning of 3rd day, this strain produced 1.58 g/L SAM when cultured in a medium containing 0.75% L-methionine and optimized carbon and nitrogen source after 6 days.
