ObjectiveUsing large sample clinical study to reevaluate the safety and efficacy of recombinant human growth hormone(ANSOMONE) in treating pediatric growth hormone deficiency(GHD).Methods1012 cases were administered with ANSOMONE at a dose of 0.1 IU · kg-1 · d -1 in bedtime for 6 months.The alteration of mean height,growth rate,height standard deviation scores,bone age,and anti-GH antibody and occurrence of adverse effects were observed.ResultsThe growth rate was promoted from ( 2.50 ± 0.85 ) cm/year to ( 13.44 ± 4.27 ) cm/year,the net growth rate was( 10.94 ±3.69)cm/year.There was significant difference between the pre-treatment and post-treatment patients ( P ＜ 0.01 ).The post-treatment anti-GH antibody positive rate was 13.34％,which had no obvious effect on the efficacy.Few patients exert transient inflammation reactions,which disappeared with any treatment.ConclusionANSOMONE had significant efficacy,and could promote the height increase obviously.It had good safety without any obvious side effect and early-maturing effect.

Objective To value the clinical application of diffusion tensor imaging (DTI) in cerebral diseases. Methods Six volunteers and 6 patients (including 3 patients with ischemic stroke and 3 patients with glioma) were examined by DTI and T1weighted, T2weighted MR scan. All data were processed with DtiStudio software to show the white matter fiber tracts. The fractional anisotropy (FA) of the diffusion tensor were measured between the affected and the unaffected side. Results The white matter fiber tract could be observed clearly on the FA map. The pyramidal tract with different degree disruption could be showed in 3 patients with ischemic stroke. Compression, displacement, infiltration or destruction of pyramidal tract, corpus callosum or internal capsule and external capsule could be seen in 3 patients with glioma, and FA was significantly reduced on the affected side as compared to the unaffected side. Conclusion Diffusion tensor imaging is useful in observing the damage and displacement of the white matter fiber tracts in vivo, beneficial to the surgical plan for patients and prognosing recovery of function.

ObjectiveTo investigate the effect of operation treating spinal multi-level tuberculosis.Methods45 patients with multi-level spine tuberculosis were treated with debridement completely and anterior or lateral-anterior intervertebrae autograft. Of them, 5 patients added to anterior instrumentation.Results45 patients had been followed up for 12 to 40 months.The back pain of 40 cases were relieved within 5 weeks after operation, erythrocyte sedimentation rate decreased 3 weeks after operation. 38 patients who involved in kyphosis decreased their kyphosis mostly and only one patient lost 3 degrees in follow-up.15 patients who involved in neurological deficits improved one or two grades (Frankel). Grafts fused in 44 patients and there were no recurrent in follow-up.Conclusions Operative treatment is efficacious to multi-level body spine tuberculosis.

ObjectiveTo discuss the effect of neonatal behavioral neurological assessment (NBNA) and developmental screening test (DST) on newborns with hypoxic ischemic encephalopathy (HIE). MethodsNBNA was performed for 60 newborns with HIE within 12-14 days and DST was also performed at 6th month after birth.ResultsMild and severe degree HIE newborns with low NBNA scores had unfavorable prognosis. Conclusions NBNA and DST can provide evidence for early interference for newborn's HIE.

· AIM: To study the in situ relative intraocular position of the iris-claw phakic intraocular lens (PIOL)for high myopia using an anterior chamber optical coherence tomography (AC OCT)prototype.· METHODS: Six PIOLs (11.50 to 22.00D lens powers) were implanted in phakic myopic eyes. Using AC OCT, tomography was taken in the anterior chamber to measure the preoperative anterior chamber depth, postoperative distance between the PIOL and the corneal endothelium (endothelial-optic distance), and the postoperative distance between the PIOL and the crystalline lens.· RESULTS: Preoperative anterior chamber depth ranged from 3.27 to 3.91 mm and the postoperative endothelial-optic distance measured 2,07 to 2,24 mm. The distance between the crystalline lens and the posterior surface of the IOL ranged from 0.82 to 1.32 mm. Several tomography revealed the position of the PIOL on the iris, The pigment layer of the iris did not seem to be disturbed by the presence of the PIOL.· CONCLUSION, The original anterior chamber depths were reduced by 36,1% to 44.6% after implantation. This study of 6 eyes revealed that tomography taken by AC OCT are useful in verifying the intraocular position of the PIOL within the anterior chamber. Adequate space was maintained between the iris-fixated phakic intraocular lens and the corneal endothelium, angle, and crystalline lens.
