目的 探讨孕母甲状腺疾病的新生儿第一个月生长速率和甲状腺功能与2岁时神经发育结局之间的相关性。方法 2013年1月—2014年12月在我院出生的156例孕母甲状腺疾病的新生儿为实验组,观察其第1个月体质量、身长及头围生长的速率,生后当天、第7天、第28天的总甲状腺素(TT4)及促甲状腺素(TSH)的水平;妊娠期无高危因素的母亲分娩的正常新生儿中随机抽取150例为正常对照组,观察生后新生儿第1个月体质量、身长及头围生长的速率,2组均在2岁内分别每3个月均接受随访评估,2岁时行贝利婴幼儿发展量表进行Bailey智力发育指数(MDI)、精神运动发育指数(PDI)的评分。采用回归分析检验新生儿生后第一个月体质量、身长及头围生长的速率,新生儿生后当天、第7天、第28天的TT4及TSH水平与中位数的差值与2岁时MDI、PDI之间的关联性。结果 ①实验组生后第1个月体质量(29.5±4.2 g/d)、身长(1.18±0.67 cm/周)及头围(0.79±0.39 cm/周)生长的速率慢于正常对照组的体质量(35.4±6.3 g/d)、身长(1.69±0.85 cm/周)及头围(1.10±0.42 cm/周)生长的速率,2组差异有统计学意义(t值分别为9.672、5.882、6.768,P均<0.05);②实验组2岁时MDI(108±15)、PDI评分(109±16)低于正常对照组MDI(115±14)、PDI评分(118±11),2组差异有统计学意义(t值分别为16.129、21.279,P均<0.05);③实验组孕母甲状腺疾病的新生儿生后第1个月体质量、身长及头围生长的速率与2岁时MDI、PDI呈正相关(相关系数分别为:0.874,0.842,0.890,0.857,0.871,0.845,t值分别为22.584,59.296,65.441,61.214,62.662,59.507,P均<0.05);④实验组孕母甲状腺疾病的新生儿生后当天、第7天及第28天的TT4及TSH水平与中位数的差值与2岁时MDI、PDI呈负相关(相关系数分别为:-0.878,-0.894,-0.890,-0.690,-0.654,-0.702,t值分别为73.167,81.273,74.166,11.523,10.548,12.103,P均<0.05)。结论 母亲妊娠期患有甲状腺疾病会影响新生儿生后第1个月体质量、身长、头围生长的速率及2岁时的精神运动、智力发育,落后于母亲妊娠期无高危疾病的正常新生儿。另外孕母甲状腺疾病的新生儿第1个月体质量、身长及头围生长的速率和生后当天、生后第7天 及第28天的T4及TSH的水平与2岁时MDI、PDI密切相关。

Objective To investigate the correlation between the growth rate, thyroid function in the first month and neurodevelopmental outcome at the age of 2 in the infants of the maternal thyroid disease. Methods We chose 156 infants of maternal thyroid disease from January 2013 to December 2014 born in our hospital as the experimental group and 150 normal infants of their mothers without high risk factors during pregnancy as the control group. We observed the rate of weight, length and head circumference growth in the first month and TT4 、TSH level at the 1^st day, 7^th day, and 28^th day after birth. We followed up two groups every 3 months up to the age of 2. We assessed Bailey mental development index (MDI) and psychomotor development index (PDI) at the age of 2. Regression analysis was used to test the correlation between the growth rate, TT4,TSH level in the 1^st month and MDI, PDI at the age of 2. Results ① The rate of growth rate in the 1^st month of the experimental group was slower than the control group. It was statistically significant difference between the two groups (P<0.05); ②MDI, PDI at the age of 2 in the experimental group were lower than those of the control group. It was statistically significant difference between the two groups (P<0.05); ③The rate of growth rate in the first month of the experimental group was positively related to MDI and PDI at the age of 2.④The difference between the level of TT4,TSH at the 1^st day, 7thday, and 28^th day and the median after birth was negatively related to MDI and PDI at the age of 2. Conclusion The maternal thyroid disease will affect the first month growth rate and neurodevelopmental outcome at the age of 2 of their infants. Their infants will grow behind than the normal newborns on pregnancy without high-risk disease.The growth rate of the first month and the level of T4 and TSH on the 1^st day, 7^th day, and 28^th day in maternal thyroid disease are closely related MDI and PDI at the age of 2.

Objective To investigate two different doses atropine make reverse effects on the function of sinus node and the atrioventricular node inhibiting action dexmedetomidine (Dex). Methods 20 healthy volunteers were included in the clinical trials aged 18~30 years (12 male, 8 female). The volunteers were administered with Dex at loading dose 1.5±0.5 μg/kg and then at 0.75±0.25 μg/(kg·h). During the trail, the volunteers who happened the minimal heart rate less than 50±5 bpm, atrioventricular node forward 2∶1 block point less than 150 bpm needed to randomly accept 0.5 mg(group A₁)or 1 mg(group A₂)atropine to antagonize(n=10). SNRT, CSNRT, AVN 2∶1 block point and AVNERP were recorded through TELAP. Results Intra-group comparison indicated functional parameters of SN and AVN were inhibited by Dexsat T₁. SNRT were prolonged (P<0.05), AVN 2∶1 block point were decreased (P<0.05),AVNERP were prolonged at T₁ compared with T₀(P<0.05). All indexes in group A₁ and AVNERP in group A₂ were back to basal level after using atropine at T₂(P<0.05). SNRT, CSNRT were shorted at T₂ compared with T₀ in group A₂(P<0.05). AVN 2∶1 block point had more increased at T₂ compared with T₀ in group A2(P<0.05). Inter-group comparison indicated no significant differences in functional parameters of SN、AVN at T₀(P>0.05). SNRT, AVNERP were shorted at T₂ in group A₂ compared with group A₁. AVN 2∶1 block point were increased at T2 in group A₂ compared with group A₁. Conclusion 0.5 mg atropine may reverse the function of SN and AVN that are inhibited by Dex. 1 mg atropine may increase functions of SN and AVN that are inhibited by Dex.

Objective To explore the effect of hyperbaric oxygenation(HBO)on behaviors of FVB mice in the open field test. Methods 9 mice of four-week-old in the HBO group were treated with hyperbaric oxygenation for a total of 21 days during two courses while 13 control mice of four-week-old did not do any treatment. After 21-day normal breeding, the mice of two groups were tested with open field test. Then, researchers observed the effect of hyperbaric oxygenation on mice behaviors after open field test. Results Compared to 13 control mice, residence time (3.73±3.69,17.97±6.82,t=-5.564,P=0.000) and the range of movement (189.65±199.32,525.67±244.22,t=-3.298,P=0.040)in central region decreased while the residence time in external region increased (296.07±3.69,281.79±6.79,t=5.597,P=0.000). The times of entering the central region and external region and crossing both of the regions decreased (3.11±3.10,8.20±4.80, t=-2.770,P=0.014;3.11±3.10,9.10±4.79,t=-3.264,P=0.005;6.22±6.20,17.30±9.59,t=-3.018,P=0.008). There was no difference in the total range of movement and the average velocity (8766.57±3362.90,8320.47±1692.47, t=0.359,P=0.726;73.05±28.02,69.34±14.10,t=0.359,P=0.726). Conclusion Hyperbaric oxygenation may change the behaviors of FVB mice in open field test to enhance its phobotaxis, anxiety degree and the cognitive ability in environment and inhibiting its exploration ability.
