Objective To discuss methods of pedicle screw fixation for thoracolumbar burst fractures among middle and old aged patients with different degree of osteoporosis, and to improve the clinical result by individualized treatment according to fracture characteristics. Methods There were totally 25 patients, 17 males, and 8 females. These patients with a mean age of 52 years (range, 43-63 years), had suffered from thoracolumbar burst fractures consisted of 1 T11 fracture, 6 T12 fractures, 8 L1 fractures, 7 L2 fractures, 3 L3 fractures. According to Jikeis osteoporosis grading system, 5 patients were of early stage, 7 of stage Ⅰ, 13 of stageⅡ. Posterior stabilization with the short-segment pedicle screw system were given to all the patients, among which 6 RF, 8 AF, 5 USS, 6 Socon were performed. Fifteen patients received anterolateral decompression, and ten patients accepted no decompression at all. Some measures were taken in order to enhance the fixation stiffness for pedicle screw system, such as increasing the screws diameter, using the vertebral body reducer to reduce the depressed vertebral body and so on. To enhance vertebral body strength after fracture union, transpedicular bone graft was also performed. Results All the patients achieved fracture union during the follow-up with a mean period of 28 months (range, 9-48 months). All of the fractures were reduced satisfactorily, SI (sagittal index) was improved from 53% to 89% after operation. No fracture of screws or rods occurred, also no screw loosened. No reduction loss was found. Conclusion In order to decrease failure rate of pedicle screw fixation for thoracolumbar fractures among middle and old aged patients, osteoporosis of vertebral body should never be neglected and, of course, treatment should be given with individualized fixation.

Objective To evaluate the prognosis of surgery in multilocular cystic renal cell carcinoma (MCRCC). Methods The characteristics of prognosis of surgery in 22 MCRCC cases out of 482 cases of renal cell carcinoma were reviewed.The MCRCC cases accounted for 4.56% of the renal cell carcinoma cases with a male-to-female ratio of 2.67∶1 in the same period.The mean age of the 22 patients was 47 years (age range,32-74 years). Results Of the 22 cases,18 underwent radical nephrectomy and 4 partial nephrectomy.The diameter of the tumors ranged 1.8-11.0 cm (mean 4.8 cm).Histological examination showed that 21 cases were of clear cell carcinoma and 1 of clear cell carcinoma mixed with granular cell carcinoma.Pathological staging showed pT 1N 0M 0 in 19 cases (86.4%),pT 2N 0M 0 in 2(9.1%) and pT 3bN 0M 0 in 1(4.5%).The classification by tumor nuclear grading system showed 5 cases (23%) of G 1 and 17 (77%) of G 2.Twenty patients were followed up for 9-56 months (mean,27.6 months) and 2 were lost of follow-up.Of the 20 patients,19 survived with no evidence of cancer and 1 died of intercurrent disease (upper gastrointestinal massive hemorrhage due to hepatocirrhosis). Conclusions MCRCC represents a distinct subtype of renal cell carcinoma.It is usually with low grade,low stage and is found incidentally.Our results indicate that MCRCC can be cured by surgery.Regardless of tumor size,the prognosis of MCRCC is favorable.

Down-regulation of adult hippocampal neurogenesis has been regarded as one of the important biological and cellular basis of depression. Recent studies have shown that there is a close correlation between neurogenesis and angiogenesis. Several angiogenesis factors, especially vascular endothelial growth factor (VEGF), play a vital role on angiogenesis. They not only have the neurotrophic and neuroprotective effects, but also up-regulate hippocampal neurogenesis. Thus,VEGF may be involved in the occurrence and treatment of major depression. This article reviews current understanding of the relationship between adult brain angiogenesis and depression.
