ve To explore the levels of boood lead of preschool children in Harbin and their impacts on the growth and development of children. Methods 310 preschool children aged 4~7 years were selected for measurement of height and weight, and for collection of fasting blood samples, determined for concentrations of lead by ICP/ MS assay. The state of lead poisoning in selected subjects was defined based on the blood lead level of ?100?g/L ruled by the standard of children's lead poisoning established by CDC in 1991 and Health Assessment Scale for Growth and Development of Children set by Academy of Preventive Medicine. Results The prevalance rate of lead poisoning a-mong selected preschool children was 14.9%. Significantly negative correlation was observed between the blood lead levels and heights (H), body weights(BW) in children aged 4~5 years (rBw = -0.158, P

Objective To summarize our clinical experience of prophylaxis and treatment for complications associated with catheterization of brachial artery. Methods 87 patients underwent endovascular treatment via brachial artery. Complications associated with catheterization of brachial artery were retrospectively analyzed. Results Under ultrasonic guidance the catheterization procedure of brachial artery was successful in all 87 patients. The success rate of cannulation was 100%. In 53 patients(61% ) ultrasonic guided cannulation was successful at the first attempt, the other 35 (39% ) with 2 or more than 2 times puncture. Complications associated with catheterization of brachial artery were detected in 16 cases. The complication rate was 18. 4%. Guidewire insertion into peri vascular compartment took place in 4 cases (4. 6% ). Episodes of local hematomas were noted in 11 cases( 12. 6% ) and in three of the 11 cases nerve injuries were detected (one of which was of late-onset type). Brachial artery pseudoaneurysm was found in 1 case(1.2%). Conclusion Familiarity with the anatomical features of the brachial access, skillful application of the techniques for the catheterization, full understanding of complications and sufficient preparation of treatment strategies can prevent those complications effectively.

Three cases of lower lumbar nerve root gangliomas with spinal instability or lumbar disc herniation are reported. The first patient was treated for lumbosacral pain and discomfort for more than 10 days. Preoperative diagnosis was L 5S 1 intervertebral instability, L 5 bilateral spondylolysis, and L 5S 1 left intervertebral foraminal space occupying lesions to be investigated, the tumor was removed intraoperatively and sent to pathology. Meanwhile, L 5S 1 posterior interbody bone graft fusion and internal fixation were performed. The second patient presented for 1 month due to left lumbar and leg pain and discomfort. Preoperative diagnosis was L 4-5 intervertebral instability and L 4-5 intervertebral disc herniation. Intraoperative exploration revealed a nerve root mass on the left side of L 5, which was surgically removed and sent to pathology. Meanwhile, posterior decompression of L 4 and L 5 intervertebral bone grafting and internal fixation were performed. The third patient presented for 4 days with right lumbar and leg pain and discomfort. Preoperative diagnosis was L 3-4, L 4-5 and L 5S 1 intervertebral disc herniation. Intraoperative exploration found a right nerve root mass of S 1, which showed invasive growth and was closely surrounded by nerve fibers. Partial resection of the mass was sent to pathology, and posterior decompression and internal fixation of L 4-5 and L 5S 1 bone grafting and fusion were performed at the same time. All 3 patients were confirmed to be ganglion neuroma by postoperative pathological examination. Three patients recovered well after surgery. Spinal ganglion cell tumor is mainly originated from primitive neural crest cell migration differentiation of sympathetic ganglion cells, and can also be derived from the sympathetic nerve and peripheral nerves. It is seen more at retroperitoneal and mediastinal, lumbosacral nerve root ganglion cells tumor is rare. Clinically, it is very close to intervertebral disc herniation and difficult to distinguish, often found during operations and less can be clearly diagnosed before operation. Surgical resection is the main treatment for ganglion cell neuroma.
