BACKGROUND:Due to special physiological and anatomical location, stability of the spine is very complicated during thoracolumbar fractures. It is difficult to identify the stability of the spine. It should be based on their individual circumstances, to explore more effective internal fixation repair method.
OBJECTIVE:To explore the Cobb’s angle and vertebral height of patients with thoracolumbar fracture and spinal cord compression treated with posterior laminectomy and screw fixation, and compared with anterior laminectomy.
METHODS:One hundred patients with thoracolumbar fracture and spinal cord compression, who were treated in the Panyu District Central Hospital from January 2013 to November 2014, were enroled in this study. The patients were equaly and randomly divided into posterior laminectomy fixation group and anterior laminectomy fixation group. Tactile and sports of American Spinal Injury Association scores, Cobb’s angle and vertebral height were assessed before treatment and 1 month after treatment, and fixation effects were compared between the twogroups.
RESULTS AND CONCLUSION:(1) No significant difference in each index was detected between the two groups preoperatively (P> 0.05). (2) Tactile and sports of American Spinal Injury Association scores, Cobb’s angle and vertebral height were better in the posterior laminectomy fixation group than in the anterior laminectomy fixation group at 1 month postoperatively (P< 0.05). (3) These findings indicated that compared with the anterior laminectomy fixation, posterior laminectomy fixation for thoracolumbar fracture combined with spinal cord compression obtained better outcomes, and could obviously relieve spinal cord compression. Posterior laminectomy fixation isasafe and effective treatment method for thoracolumbar fracture and spinal cord compression.

Objective To evaluate the efficacy and safety of the bundles of treatment protocol for patients with acute brain injury (ABI) complicated by acute lung injury (ALl)/acute respiratory distress syndrome (ARDS).Methods A total of 83 patients with acute brain injury complicated by ALI/ARDS were randomly divided into experimental group (n =41) and control group (n =42).The control group was treated with the routine bundle protocol while the experimental group was treated with an intensive bundle protocolin addition to the routine bundle protocol.The data was collected,and the effectiveness and safety of the two bundles of treatment protocol were evaluated.Results The results of heart rate (HR),SpO2,and PO2/FiO2 in the two groups showed significant differences before and after treatment.The improvement of PO2/FiO2 in the experimental group occurred earlier and was more significant compared tothe control group,24 hours after treatment.The mechanical ventilation time,ICU stay time,and total hospitalization time for the experimental group were significantly different (P ＜ 0.05) from the control group.The 28-day mortality and morbidity of ventilator-associated pneumonia showed no significant difference (P ＞ 0.05) between the two groups.Conclusion The treatment of acute brain injury complicated by ALI/ARDS by the two bundles of treatment protocol is effective.Compared to the conventional treatment bundles,the intensive treatment bundles can significantly improve oxygenation,and shorten the mechanical ventilation time required,as well as ICU and total hospital stay.

Objective To investigate the effect of microRNA-1 (miR-1) on the fibrosis of cardiac fibroblasts induced by high glucose. Methods The primary cultured fibroblasts from 1-3 days old Sprague-Dawley (SD) rats, were randomly divided into 4 groups (n = 3): normal glucose + lentivector-vehicle (CON+Lv-Vehicle group), normal glucose + lentivector-miR-1 (CON+Lv-miR1 group), high glucose + lentivector-vehicle (HG+Lv-Vehicle group), high glucose + lentivector-miR-1 (HG+Lv-miR1 group). Fibroblasts were cultured in glucose concentration 5.5 mmol/L and 25 mmol/L DMEM culture, and were injected lentiviral vector carrying miR-1 silencer sequence or the same volume of lentiviral vector. After 12 hours, the medium was replaced with fresh complete medium. After 3 days when transfection efficiency was up to 90%, the cellular miR-1 content was detected by real-time reverse transcription-polymerase chain reaction (qRT-PCR). The secretion of collagen Ⅰ and Ⅲ were measured by enzyme linked immunosorbent assay (ELISA). Expression of collagen Ⅰ and Ⅲ, matrix metalloproteinase 2 and 9 (MMP-2, MMP-9), autophagy related protein LC3B-Ⅱ, P62/SQSTM1 and Cathepsin D were assessed by Western Blot. Results Compared with the CON+Lv-Vehicle group, the content of miRNA in the CON+Lv-miR1 group had no statistical significance. Compared with the CON+Lv-Vehicle group, high glucose increased the amount of miR-1 (2-ΔΔCt: 1.82±0.17 vs. 1.00±0.04), collagen Ⅰ and Ⅲ secretion (mg/L: 14.55±0.33 vs. 7.28±0.22, 157.50±13.22 vs. 61.25±8.54) and expression (gray value: 432.35±56.00 vs. 100.00±15.00, 320.35±47.00 vs. 100.00±15.00), the level of MMP-2, MMP-9 and the expression of autophagy related protein LC3B-Ⅱ and P62/SQSTM1 (gray value: 249.0±21.0 vs. 100.0±15.0, 142.3±20.0 vs. 100.0±16.0, 178±19 vs. 100±14, 378.3±20.0 vs. 100.0±15.0), decreased the expression of lysosomal associated protein Cathepsin D (gray value: 60±14 vs. 100±10), and the differences were statistically significant (all P < 0.01). Compared with the HG+Lv-Vehicle group, the amount of miR-1 in the HG+Lv-miR1 group was significantly decreased (2-ΔΔCt: 1.21±0.10 vs. 1.82±0.17), collagen Ⅰ and Ⅲ secretion (mg/L: 10.68±0.54 vs. 14.55±0.33, 87.25±13.55 vs. 157.50±13.22) and expression (gray value: 179.41±45.00 vs. 432.35±56.00, 173.41±50.00 vs. 320.35±47.00), the level of MMP-2, MMP-9 and the expression of autophagy related protein LC3B-Ⅱ and P62/SQSTM1 (gray value: 172.0±23.0 vs. 249.0±21.0, 90.0±17.0 vs. 142.3±20.0, 138±15 vs. 178±19, 265.0±17.0 vs. 378.3±20.0) in the HG+Lv-miR1 group were decreased and the expression of lysosomal associated protein Cathepsin D was higher (gray value: 110±17 vs. 60±14), and the differences were statistically significant (all P < 0.05). Conclusions The expression of miRNA-1 was up-regulated in cardiac fibroblasts cultured in high glucose, and miRNA-1 silencing inhibited cardiac fibroblast induced fibrosis in high glucose. The mechanism may be related to the recovery of autophagy flux, up-regulation of Cathepsin D expression and inhibition of collagen production.

ObjectiveTo investigate the effect of vascular endothelial growth factor (VEGF) on collagen Ⅱ expression in rat articular chondrocytes in vitro.MethodsChondrocytes were isolated and cultured.Then rats were divided into 4 groups:group A(control):without any intervention; group B:10 ng/ml VEGF was added; group C:10 ng/ml IL-1β was added; group D:10 ng/ml VEGF and 10 ng/ml IL-1β were added.Messenger RNA (mRNA) expression of collagen Ⅱ was detected by using real time polymerase chain reaction (real time PCR),and the protein expression level of collagen Ⅱ was detected by Western blotting.Comparisons between groups were performed by one-way ANOVA.ResultsThe collagen Ⅱ mRNA expression levels of group B (0.78+0.07),group C (0.67+0.06) and group D (0.57+0.04) were significantly lower than those of the group A (1.00±0.08),and there was significant difference between B and D,C and D.Compared with group A(0.95+0.21),the expression of collagen Ⅱ protein in group B(0.71+0.14),group C(0.60±0.11) and group D(0.31 +0.09) was significantly suppressed.The expression of collagen Ⅱ protein in group D was significantly lower than those of group B and C.ConclusionVEGF can significantly suppress the expression of collagen II in rat articular chondrocytes.VEGF may play an important role in the development of osteoarthritis.

As an important indicator of total hip arthroplasty (THA) the rate and degree of offset reconstruction play an important role in improving the prognosis and life quality of patients. The reconstruction of femoral offset is closely related to reserved length of calcar femorale, the head and neck length of prosthesis, angle degree of neck shaft and whether lower limb is isometric. Reconstruction strategy includes making a meticulous and standard measurement before the surgery, predicting the reserved length of calcar femorale, selecting a prosthesis with approximate anatomical neck-shaft angle and reconstructing offset by adjusting the head and neck length of the prosthetic during the operation. The aim of this article was to introduce the research progress and influence of offset on hip function, prosthetic wear and postoperative complications such as pain, limp and unequal leg length, and to discuss the reconstruction strategy.
