There were 528 amblyopic children were set as the observation group, 500 healthy children who were treated in our hospital at the same time were set as the control group. Single factor analysis and multiple logistic regression analysis were carried out for children with amblyopia. ·RESULTS:In a survey, the incidence rate of amblyopia among young children in Shaanxi Xi'an was 5. 14%. Ametropic amblyopia accounted for the highest proportion (61. 4%), and lesion extent was usually mild to moderate, ametropic amblyopia accounted for 24. 1%, which was inferior to that was the strabismus accounted as 12. 9%, rare were form deprivation amblyopia accounted for 1. 7%. General data analysis showed that, there were significant differences between the two groups in maternal gestational age, gestational weeks and times of pregnancy, smoking history of parents, family genetic history of myopia (P<0. 05). Multivariate logistic regression analysis showed that pregnancy when old, mother's smoking history, family genetic history of myopia and short gestational weeks were risk factors for amblyopia in young children (P<0. 05). · CONCLUSION: There is a certain oneset risk of amblyopia in young children in Shaanxi Xi'an. Attention should be paid to educate eye care knowledge, organize regular visual screening, ensure early detection, early diagnosis, early treatment.

AIM:To evaluate the efficacy and safety of Sub-tenon's anesthesia for compound trabeculectomy with high intraocular pressure.
METHODS: Forty - six eyes ( 46 cases ) of primary glaucoma received compound trabeculectomy under Sub-tenon's anesthesia, whose preoperative intraocular pressure were higher than normal after 24 to 48h of combined medication. Both efficacy and complication of the anesthesia were studied.
RESULTS: One minute after anesthetic injection, all cases were able to achieve the effect of analgesia and eye brake. During the operation, 0 level of anesthesia effect included 35 eyes ( 76%) , 1 level of anesthesia effect included 10 eyes ( 22%) , 2 level of anesthesia effect included 1 eye(2%). Only 1 case of these patients needed to add the surface anesthetic once, and other cases were successfully operatedunder Sub-tenon's anesthesia. The total effective rate was 98%. No anesthesia complications occurred in all cases.
CONCLUSION: Sub - Tenon's anesthesia is safe, effective, simple and quick for compound trabeculectomy with high intraocular pressure.

Bone marrow mesenchymal cells (BMSCs) are regarded as donor cells in cell transplantation therapies for spinal cord injury (SCI) for they have the ability of favourable proliferation and multi-directional differentiation, and are easily isolated and culturd and have less immunological reaction. It has been confirmed that subarachnoid space injection is the most ideal delivery technique of BMSCs. Bone marrow mesenchymal stem cells transplantation is safe and its reconditioning role is certain for SCI in early clinical application. The mechanism of BMSCs promoting functional recovery after SCI is probably concerned with vicarious function, nerve trophism, immunosuppression and promoting axonal regeneration by BMSCs.
