目的 分析矮小症学龄儿童血液内血钙(Ca)、镁(Mg)、铁(Fe)、锌(Zn)水平与体格发育的相关性.方法 选择2016年1月至2017年8月来医院儿保门诊就诊的50例矮小症学龄儿童作为观察组,选择同期来我院体检的50例正常儿童作为对照组,均采集静脉血测定血清Ca、Mg、Fe、Zn水平,并进行体格检查,测定身高、胸围、体重,采用世界卫生组织推荐的美国国家卫生统计中心(NCHS)制定的相关标准评价其体格发育情况,分析矮小症儿童血清钙、镁、铁、锌等矿物质水平与其体格发育的相关性.结果 观察组身高、胸围、体重及血清Ca、Fe、Zn水平均低于对照组,比较差异有统计学意义(P<0.05);观察组低钙、低铁、低锌检出率均高于对照组,比较差异有统计学意义(P<0.05);矮小症学龄儿童血清Ca水平与身高、体重、胸围呈正相关,Fe与身高呈正相关,Zn与身高、体重、胸围均呈正相关(P<0.05).结论 矮小症学龄儿童血清Ca、Fe、Zn水平低于正常健康儿童,且缺钙、缺铁、缺锌均影响儿童体格发育. 相似文献

目的分析生长激素缺乏症(GHD)和特发性矮小症(ISS)患者生长激素激发试验结果,及其与重组人生长激素(rhGH)治疗反应之间的关系。方法回顾性分析36例GHD和24例ISS左旋多巴和胰岛素低血糖生长激素激发试验结果,rhGH治疗后身高增长情况,进行相关性分析。结果 GHD组两种激发试验峰值、曲线下面积(area under curve, AUC)与身高标准差比值(SDS)呈正相关(P0.001),校正性别、年龄、骨龄、体质量SDS后,左旋多巴激发试验峰值及AUC与身高SDS仍呈正相关(r=0.471和0.427,P0.05);ISS组并无此相关性。两组治疗前身高SDS无差异,治疗第2年GHD组身高SDS显著高于ISS组(P0.05)。两组治疗后GV均明显增加,但治疗第2年GV较第1年有所下降。GHD组治疗第1年GV与治疗前两种激发试验峰值、AUC呈负相关,而ISS组并无相关性。结论 rhGH可显著改善GHD和ISS患儿身高,但随着治疗的延长GV有下降趋势;治疗前GH激发试验可一定程度预测GHD患儿rhGH治疗效果,但不能预测ISS患儿rhGH治疗效果。 相似文献

探讨胰岛素样生长因子-1(IGF-1)和胰岛素样生长因子结合蛋白-3(IGFBP-3)在矮小症患儿诊断中的价值.对青春发育前矮小症患儿92例,健康儿童(对照组)48名,用精氨酸激发试验和胰岛素低血糖激发试验检测血清生长激素(GH)水平,并根据患儿GH峰值分为完全性生长激素缺乏(CGHD组,20例)、部分性生长激素缺乏(PGHD组,38例)、特发性矮小(ISS组,34例).采用CLIA检测血清IGF-1和IGFBP-3.对CGHD组、PGHD组、ISS组和对照组血清IGF-1和IGFBP-3水平进行两两比较发现,除PGHD组和ISS组间无显著性差异外(P>0.05),均有显著性差异(P<0.01).本文结果显示血清IGF-1和IGFBP-3检测对矮小症患儿有重要意义,可以作为确诊CGHD有价值的指标,但对于PGHD和ISS患儿则需结合GH激发试验加以鉴别. 相似文献

Purpose
It has been reported that daily recombinant human growth hormone (GH) treatment showed beneficial effects on growth in prepubertal children with idiopathic short stature (ISS). The present study aimed to validate the GH (Eutropin®) effect on growth promotion and safety after short-term GH treatment.Materials and Methods
This study was an open-label, multicenter, interventional study conducted at nine university hospitals in Korea between 2008 and 2009. Thirty six prepubertal children with ISS were enrolled in this study to receive 6-month GH treatment. Yearly growth rate, height standard deviation score (SDS), and adverse events were investigated during treatment.Results
After 26 weeks of GH treatment, the height velocity significantly increased by 6.36±3.36 cm/year (p<0.001). The lower end of one-sided 95% confidence interval was 5.22 cm/year, far greater than the predefined effect size. The gain in height SDS at week 26 was 0.57±0.27 (p<0.0001). Bone age significantly increased after GH treatment, however, bone maturation rate (bone age for chronological age) showed limited advancement. This 26-week GH treatment was effective in increasing serum levels of insulin-like growth factor (IGF)-I and IGF binding protein (IGFBP)-3 from baseline (p<0.0001). Eutropin was well tolerated and there were no withdrawals due to adverse events. No clinically significant changes in laboratory values were observed.Conclusion
This 6-month daily GH treatment in children with ISS demonstrated increased height velocity, improved height SDS, and increased IGF-I and IGFBP-3 levels with a favorable safety profile. 相似文献12.

To study the effects of regular football training on basal and exercise induced levels of growth hormone (GH) and insulin-like
growth factor (IGF-1), 13 young football players were investigated by a submaximal exercise at the beginning of the sporting
season in October (S1), at the middle of the season in January (S2) and at the end in May (S3). At each session, an exercise
test on an ergogycle was performed for 25 min, beginning with an incremental exercise to reach 90% of theoretical maximal
heart, which was maintained for the last 10 min of the test. Venous blood samples were collected at rest, at the end of the
exercise and at 30 and 60 min during the recovery period. Plasma lactate and glucose concentrations increased during exercise
with no difference found between sessions. GH level increased with exercise at each session but the response was significantly
higher in S1 than in S2 and S3 (P<0.01). The GH area under the curve decreased significantly all along the football season (P<0.01); the IGF-1 level did not significantly change during exercise nor with training. Basal insulin-like growth factor binding
protein-3 (IGFBP3) remained stable during the three sessions. Football training decreased significantly the exercise-stimulated
GH levels all along the football season but did not have any significant effect on IGF-1 levels or on basal IGFBP3 levels. 相似文献

Aging is associated with progressive decline of skeletal muscle mass and function. This condition, termed sarcopenia, is associated with several adverse outcomes, including loss of autonomy and mortality. Due to the high prevalence of sarcopenia, a deeper understanding of its pathophysiology and possible remedies represents a high public health priority. Evidence suggests the existence of a relationship between declining growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels and age-related changes in body composition and physical function. Therefore, the age-dependent decline of GH and IGF-1 serum levels may promote frailty by contributing to the loss of muscle mass and strength. Preclinical studies showed that infusion of angiotensin II produced a marked reduction in body weight, accompanied by decreased serum and muscle levels of IGF-1. Conversely, overexpression of muscle-specific isoform of IGF-1 mitigates angiotensin II-induced muscle loss. Moreover, IGF-1 serum levels have been shown to increase following angiotensin converting enzyme inhibitors (ACEIs) treatment. Here we will review the most recent evidence regarding age-related changes of the GH/IGF-1 axis and its modulation by several interventions, including ACEIs which might represent a potential novel strategy to delay the onset and impede the progression of sarcopenia. 相似文献

The genetic alterations of vitamin D receptor (VDR) are related with the growth of long bone. There were a lot of reports regarding an association of polymorphisms in the VDR promoter with many disorders, but not with idiopathic short stature (ISS). We investigated the association of them with ISS. A total of 50 subjects, including 29 ISS patients and 21 healthy controls with their heights within the normal range was recruited. We selected two single nucleotide polymorphisms (SNPs) from VDR promoter (rs11568820 at the Cdx-2 binding site upstream of exon 1e and rs4516035 at -1012 upstream of exon 1a) as candidates, respectively. In genotype analysis, the frequency of A/A genotype at the Cdx-2 binding site locus (rs11568820) upstream of exon 1e of VDR was decreased to 6.9% in ISS patients (28.6% in controls) (P = 0.027). The genetic variation at the Cdx-2 binding site of VDR promoter can be a contributing factor of growth of height. 相似文献
