OBJECTIVETo compare the clinical curative effect of thoracolumbar burst fracture treated by the posterior unilateral approach corpectomy fusion screw-rod fixation and anterior corpectomy bone fusion screw plate fixation.

METHODSFrom January 2008 to May 2014,36 cases of thoracolumbar burst fracture underwent operation of decompression, fusion, and internal fixation was retrospective analyzed. Among them, 16 patients were treated through posterior approach as posterior group, including 13 males and 3 females aged from 37 to 62 years old; 9 cases caused by falling injury, 3 cases by traffic accident injury,4 cases by heavy aboved;the injury segment was on T₁₂ in 2 cases, L₁ in 5 cases, L₂ in 7 cases, L₃ in 2 cases; according ASIA grade, 3 cases were grade A, 2 cases were grade B, 2 cases were grade C, 5 cases were grade D, 4 cases were grade E; the time between injury and operation ranged from 5 to 15 days. Other 20 patients were treated through anterior-lateral approach as anterior-lateral group, including 15 males and 5 females with age from 27 to 62 years old; 12 cases caused by falling injury, 4 cases by traffic accident injury, 4 cases by heavy aboved; the injury segment was on T₁₂ in 2 cases, L₁, in 7 cases, L₂ in 9 cases, L₃ in 2 cases; for ASIA grade: 4 cases were grade A, 2 cases were grade B, 4 cases were grade C, 6 cases were grade D, 4 cases were grade E; the time between injury and operation ranged from 4 to 12 days. The operation time, bleeding during operation and postoperative drainage volume were observed in two groups,and the changes of nerve function of ASIA grade, clinical efficacy,improved degree of thoracic and lumbar lordosis,and bony fusion were compared between two groups.

RESULTSAll patients were followed up from 12 to 24 months with an average of (15.8 ± 3.3) months. The operation time, bleeding during operation, and postoperative drainage volume had no significant different between two groups (P > 0.05). As compared with preoperative, ASIA grade of two groups at last follow-up had statistically significantly different (P < 0.01), the neural function of two groups after operation was recovered for different extent. The JOA score of two groups was compared between last follow-up and preoperative, the difference had statistically significant (P < 0.01), the two groups showed good clinical effect. The clinical results of ASIA grade, JOA score and RIS had no significant differences between two groups. All patients of two groups were obtained fusion. Thoracic and lumbar lordosis angle improvement degree had no significant difference between two groups ,it bad significant difference had statistical significance compared with preoperative, the two approaches could effectively restore the spinal sequence.

CONCLUSIONFor patients with thoracolumbar burst fracture just treated by anterior decompression and reconstruction of anterior column, according to the degree of operation performer' skill proficiency and the patient' condition to choose, but for patients must performed the spinal canal decompression anterior and posterior, the three column-reconstruction to required anterior-posterior approach, the posterior unilateral approach corpectomy fusion screw-rod fixation obviously shorten operation time, reduce the operation wound, it is worth the clinical promotion.

Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

Objective To measure the levels of monocyte chemoattractant protein-1 (MCP-1) in the aqueous humor of patients with acute primary angle-closure glaucoma (APACG),and its correlation with the patients' prognosis after trabeculectomy.Methods This retrospective case-control study included 19 patients with APACG who experienced a failed trabeculectomy (case group) and 57 age-and sex-matched patients with APAGG who underwent successful trabeculectomy (control group).Aqueous humor was collected before trabeculectomy for the detection of MCP-1 levels in the both groups by enzyme-linked immunosorbent assay.And finally,logistic regression analysis was applied to assess the risk factors for failed trabeculectomy.Results The MCP-1 concentration in aqueous humor was (5688.04 ± 2099.99)ng · L-1 in the case group and (2077.57 ± 568.44)ng · L-1 in the control group,and the difference between both groups were significant (P ＜ 0.001).Logistic regression analysis revealed MCP-1 level (OR =1.005;95％ CI =1.001-1.008) and a shallow anterior chamber after surgery (OR =31.430;95％ CI =1.577-57.350) were the independent risk factors for failed trabeculectomy procedures.Conclusion MCP-1 levels in aqueous humor are higher in APACG eyes with failed trabeculectomy than those with successful one during 1-year follow-up,so MCP-1 level is considered as an independent risk factor for failed trabeculectomy.

Objective is designed to observe the effect of the low molecular protein "SL Hong-Xin Blood-Increasing Capsules" on human iron deficiency anemia. Altogether 110 school children, 7 - 12 years old, with iron deficiency anemia (Hb < 120 g/L) were enrolled in this trial and were randomly and evenly divided into two groups. In the treatment group (n = 55), the "SL Hong-Xin Blood-Increasing Capsules" were orally adminitered for 30 days, two capsules at one time and two times a day, whereas in the control group (n = 55) blank capsules were given to the children in the same way as in the treatment group. Before and at the end of the trial period, peripheral blood samples were taken from fringers of the children to determine Hb content, hematocrit percentage, and free protoporphyrin content in red blood cells. Results showed that after trial the Hb content was (15.9 +/- 9.6) g/L in the treatment group, while that of the control group was only (5.3 +/- 4.3) g/L (P < 0.001). The hematocrit percentage markedly increased (P < 0.001) and protoporphyrin level markedly decreased (P < 0.001). In conclusion the active ingredient of "SL Hong-Xin Blood-Increasing Capsules" is low molecular protein iron, which is markedly effective for elevating Hb content and hematocrit percentage, and effective for decresing protoporphyrin content of children with iron deficiency anemia. Hence, the capsules could be used to improve nutritional anemia in children based on the "Functional Evaluation Procedure and Test Methods For Health-Care Food".
