It has done a lot investigation on the microneurosurgery technique and monodrama operations, performed different kinds of complicated and difficult operations successfully such as resection of cranial basis tumors , cerebrovascular disease, resection of pituitary tumor by nose way , resection of spinal cord tumors, spinal cord congenital malformation .

是国内较早开展显微神经外科手术单位之一。在显微神经外科技术和微创手术方面做过许多研究，成功完成了各种神经外科疑难与复杂手术，如颅底肿瘤的显微手术、脑血管病的微创与介入手术、经鼻蝶入路垂体瘤切除手术、脊髓髓内肿瘤、脊髓先天性畸形的显微手术等。

Based on NewGA, the thesis proposes a multigroup parallel genetic algorithm with simulated annealing method , then combines MPGASA with BPNN. According to whether simulated anealing method is used or not, two parallel genetic neural networks are implemented respectively. Results show that PGANN_SA is superior to PGANN and NewGANN.
