A study of reference intervals for serum thyrotropin and thyroid hormones during the neonatal period for the healthy term newborns in Suqian / 中华内分泌代谢杂志

Objective To establish thyrotropin( TSH) and thyroid hormones reference ranges during the neonatal period for the healthy term newborns in Suqian. Methods Blood samples from a heel-prick were collected from 500 healthy newborns 72 hours after birth to determine the level of TSH. 200 healthy newborns were chosen to determine the levels of serum TSH and thyroid hormones on the 14th day of life, and then compared with the results from 120 healthy adults. Results The reference range of TSH at 72 hours after birth was 0. 46-6. 59 mIU/ L. The reference ranges of TT3 , TT4 , TSH, FT3 , FT4 on the 14th day of life were 1. 10-2. 62 nmol/ L, 81. 10-158. 28 nmol/ L, 0. 83-6. 39 mIU/ L, 3. 76-6. 66 pmol/ L, and 10. 67-22. 27 pmol/ L, respectively. There was no significant difference in the interval of TSH between newborns and adluts, whereas there were significant difference in the intervals of TT3 , TT4 , FT3 , and FT4 between the two groups. Conclusions The establishment of TSH and thyroid hormone reference ranges during the neonatal period for the healthy term newborns could improve our understanding of the thyroid function during the neonatal period for the healthy term newborns, and our data suggests lowing the initiatory screening cut-off point of congential hypothyroidism.

Impact and Enlightenment of Aging of Population on Medical Device Market / 医疗卫生装备

In recent years,the United States analyzing the aging of the population brought by the increase in cardiovascular diseases such as medical equipment and its impact on the U.S. market-oriented role,combined with the present condition of population and medical device market of China,the trend of aging is pointed out and that there is a great potential market of medical device for cardiovascular disease in China,but some problems still exist,such as high price,low public acceptance,etc. According to relevant policies,corresponding suggestions were proposed for domestic medical device companies to enhance their R&D capability and adaptability to the medical system reform.
