Alpha-fetoprotein reactive to pisum sativum agglutinin (AFP-R-P) in liver tumor tissues, surrounding noncancerous tissues and peripheral blood from 25 cases of primary liver cancer were measured. Their medium and standard deviation were 41 ?26%, 30?27% and 36?25%, respectively. AFP-R-P levels were lower in the tumors with a diameter of less than 3cm, intact capsule, no invasion of surrounding liver tissues and no tumor thrombus. The patients with lower AFP-R-P levels had a longer survival. The results indicate that AFP-R-P is secreted mainly by tumor cells possessing more malignant behaviour, diffused directly in surrounding liver tissues and entered into peripheral blood, resulting in elevated serum AFP-R-P.

Objective: To investigate the treatment of nasal deformity in patients with unicoronal craniosynostosis. Methods: In patients over 6 months old, the nasal bones were wedge-removed without fixation. The management of all patients with unicoronal craniosynostosis was distraction osteogenesis of pedicled unilateral frontal bone flap. Results: Postoperative extended distance of the frontal bone was 28—41 mm (mean, 35.4 mm). After extension, three-dimensional reconstruction of cranial CT was carried out, which showed that CVAI was 0.8—1.2 (mean, 0.98), tending to normal. After discharge, dynamic cranial braces were put on for 1 year. Postoperatively, the children were followed up for 8—36 months (mean, 28 months). The shape and nasal deformity of all children were improved compared with those before surgery. Conclusions Nasal wedge resection should be used to correct nasal deformity in children over 6 months with unicoronal craniosynostosis.
