摘 要:目的探讨青春前期特发性矮小症(ISS)患儿重组人生长激素(rhGH)治疗前后血清骨形成指标Ⅰ型前胶原氨基端前肽(PINP)及骨吸收指标Ⅰ型胶原交联羧基末端肽(β-CTX)水平变化及其在早期治疗随访体系中的临床意义。方法ISS组患儿40例(男18例,女22例),健康对照组儿童50例,ISS组患儿予rhGH0.15IU/(kg·d),每晚皮下注射,治疗前、治疗3个月及6个月后分别采用电化学发光法测定其血清PINP、β-CTX、胰岛素样因子-1(I GF-1)及胰岛素样生长因子结合蛋白-3(IGFBP3)水平,并记录身高、体质量、体质量指数、身高标准差积分(HtSDS)、骨龄、生长速度。结果1.青春前期ISS组血清PINP水平[(479.51±134.61)μg/L]均低于健康对照组PINP[(651.31±212.41)μg/L],β-CTX水平[(0.84±0.33)μg/L]高于健康对照组[(0.50±0.15)μg/L],差异均有统计学意义(t=2.276、-2.709,P均〈0.05)。2.ISS男童(18例)及女童(22例)GH治疗前后血清PINP及β-CTX差异无统计学意义(P〉0.05);40例ISS患儿GH治疗后3个月,血清PINP水平[(736.15±156.59)μg/L]及β-CTX水平[(1.08±0.27)μg/L]较治疗前均有升高,差异有统计学意义(t=4.736、2.497,P均〈0.05),其中PINP尤为显著,HtSDS(-2.95±0.43)与治疗前HtSDS(-2.69±0.58)比较差异有统计学意义(t=2.714,P〈0.05);治疗6个月与3个月比较,PINP水平(860.90±254.59)μg/L及β-CTX水平(0.94±0.32)μg/L增加缓慢(t=1.366、-0.831,P均〉0.05),HtSDS(-2.51±0.54)与治疗后3个月比较差异无统计学意义(t=1.609,P〉0.05)。3.血清PINP与IGF-1、IGFBP3呈正相关性(r=0.636、0.673,P均〈0.05),与β-CTX无相关性(r=0.336,P〉0.05),PINP、β-CTX与HtSDS呈正相关(r=0.655、0.782,P均〈0.05)。结论骨转换指Objective To detect the levels and study the clinical significance of serum procollagen type Ⅰ amino - terminal propeptide (PINP) and β - C - telopeptides of type Ⅰ collagen ( β - CTX) as bone turnover markers in recombinant human growth hormone (rhGH) treatment of prepuberty idiopathic short stature (ISS) children. Methods Forty patients of ISS ( 18 boys and 22 girls) had been collected and treated with GH 0.15 IU/( kg · d) injection every night. Serum levels of PINP, β - CTX, insulin - like growth factor 1 ( IGF - 1 ) and insulin - like growth factor binding protein 3 (IGFBP3) were measured by electrochemiluminescence immunoassay in ISS before treatment and after 3,6 months,and they were also measured in 50 healthy children of the healthy control group,and the height, weight, body mass index, height standard difference score ( HtSDS), bone age and growth rate were recorded. Results ( 1 ) In ISS group ,the serum level of PINP[ (479.51 ± β4.61 ) μg/L] was lower than that of the healthy control group [ (651.31 ±212.41 ) μg/L], the level of β -CTX [ (0.84 ±0.33 ) μg/L] was higher than that of the healthy control group [ (0.50 ±0.15 ) μg/L ]. The differences were statistically significant ( t = 2. 276, - 2. 709, all P 〈 0.05 ). (2) The serum levels of PINP and β - CTX had no significant difference in 18 boys and 22 girls before and after GH treat- ment (P 〉0.05) of ISS. After 3 months of GH treatment,the serum levels of PINP[ (736.15±156.59) μg/L] and β - CTX [ ( 1.08 ± 0.27 ) μg/L ] were higher than those before treatment in 40 cases, and the difference was statistical- ly significant ( t = 4. 736,2.497, all P 〈 0.05 ), as the increase of PINP was particularly significant. HtSDS ( - 2.95 ± 0.43) ,compared with before treatment ( -2.69 ±0.58) ,was significantly different (t =2. 714,P 〈0.05). However, after 6 months of GH treatment,the levels of PINP[ (860.90 ±254.59) μg/L] and β - CTX[
