Chinese Journal of Contemporary Pediatrics 2016;18(3):247-253
OBJECTIVETo investigate the efficacy and safety of different doses of recombinant human growth hormone (rhGH) in the treatment of short stature in children born small for gestational age (SGA).
METHODSA total of 37 children with short stature born SGA were enrolled, and based on the dose of rhGH treatment, they were divided into low-dose rhGH group (0.1-0.15 IU/kg daily) and high-dose rhGH group (0.16-0.2 IU/kg daily). The changes in height standard deviation score (ΔHtSDS), height velocity (HV), serum levels of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3), and fasting blood glucose at 3, 6, 9, 12, and 24 months after treatment were compared between the two groups.
RESULTSΔHtSDS and HV both increased after the treatment with high- and low-dose rhGH, but ΔHtSDS and HV in the high-dose rhGH group were significantly higher than in the low-dose rhGH group 9, 12 and 24 months after treatment (P<0.05). Both high- and low-dose rhGH treatment increased serum levels of IGF-1 and IGFBP-3. Serum levels of IGF-1 and IGFBP-3 were positively correlated with HtSDS in both groups. One child each in the high- and low-dose rhGH groups experienced transient slight increase in fasting blood glucose (6.1 mmol/L). There were no cases of abnormal thyroid function.
CONCLUSIONSrhGH has good efficacy in the treatment of short stature in children born SGA, with few adverse events, and high-dose rhGH has some advantages over low-dose rhGH.

OBJECTIVETo evaluate the difference of clinical outcomes and radiological outcomes through meta-analysis on the total hip arthroplasty (THA) between hydroxyapatite(HA) coating and non-HA coating femoral stems.
METHODSWe searched the MEDLINE, Embase, Cochrane library and CBM for published randomized controlled trial (RCT) comparing HA coating and non-HA coating femoral stems in primary THA clinical outcomes with Harris hip score and incidence postoperative thigh pain, radiological outcomes with presence of endosteal condensation and radioactive line on the prothesis, heterotopic ossification. Data analysis were performed using RevMan 5.0(the Cochrane Collaboration).
RESULTSTen studies and 917 hips into our analysis, with 464 hips in HA groups and 453 hips in non-HA groups. The combined results of the meta-analysis indicated there was no statistical differences between the two groups on postoperative Harris hip score(WMD = 3.04, 95%CI:-4.47-10.54, P = 0.43) , there was statistical difference on incidence postoperative thigh pain (RR = 0.56, 95%CI:0.33-0.94, P = 0.03) . There were no significant differences between the two groups on presence of endosteal condensation (RR = 1.01, 95%CI:0.91-1.11, P = 0.91), presence of radioactive line (RR = 0.99, 95%CI:0.88-1.11, P = 0.83) and incidence of heterotopic ossification (RR = 0.97, 95%CI:0.77-1.21, P = 0.77).
CONCLUSIONSThere are no clinical and radiological benefits in the use of HA coating femoral stems in Primary THA, there is not enough evidence prove the HA can reduce the incidence postoperative thigh pain.
