Chinese Journal of Interventional Cardiology 1993;0(02):-
Objective To investigate the correlation between abnormal lipid metabolism and coronary artery lesions. Methods Two hundred and sixty seven patients were devided into the control group ( n =101) and the coronary heart disease (CHD) group ( n =166), which included single vessel lesion ( n =54), double vessel lesions ( n =68) and triple vessel lesions ( n =44) according to coronary angiography. At the same time the lipid components were examined and the ralationship between serum lipid level and coronary artery lesions were analysed. Results Compared with the control, the total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and triglyceride (TG) level were significantly elevated while but high density lipoprotein cholesterol (HDL-C) was lowered in the CHD group. The severity of coronary lesions was increased with the elevation of TC, LDL-C, apolipoproteinB (ApoB), TC/HDL-C, LDL-C/HDL-C, and the reduction of HDL-C. There were significant differences in terms of lipid level beteewn the CHD group and the control. The analysis showed that TC/HDL-C and LDL-C/HDL-C were most directly correlated with the coronary artery lesions in the CHD group. Conclusion The results suggest that the severity of coronary artery lesions correlated with abnormal lipid metabolism, and LDL-C/HDL-C, TC/HDL-C are better indicators than other lipid components.

BACKGROUND:Though the effects of conservative or traditional open reduction and internal fixation in the treatment of thoracolumbar fractures are reliable and satisfactory for most cases, two methods also have shortages. Minimal-invasive percutaneous pedicle screw system provides a new available method. OBJECTIVE:To investigate the clinical effect of Sextant percutaneous pedicle screw system in the treatment of thoracolumbar fractures. METHODS:A total of 55 patients, who had undergone percutaneous pedicle screw fixation using Sextant system (25 patients) or traditional open internal fixation (30 patients) for single-level vertebral body compression fractures in Department of Orthopedics of Renmin Hospital of Wuhan University from February 2011 to January 2013, were enrol ed in this study. RESULTS AND CONCLUSION:Except two patients in traditional open internal fixation group were lost after discharge, al other patients were fol owed up for 8-14 months. Operative time, intraoperative blood loss, postoperative drainage amount and hospital day were better in percutaneous pedicle screw fixation group than in the traditional open internal fixation group (P<0.05). Compared with preoperation, the sagittal Cobb angle, visual analogue scale and Oswestry disability index after operation were significantly lower (P<0.05), while anterior vertebral body height ratio was significantly higher in each group (P<0.05). No significant difference was found in terms of correction loss and Oswestry disability index between two groups at 8 months after operation (P>0.05). The results show that percutaneous pedicle screw fixation using Sextant system has a satisfactory outcome in the treatment of thoracolumbar fractures. However, obeying indication strictly is very important for clinical application.

Objective To investigate the effects of caveolin-1 overexpressing on the growth of cervical squamous cell cancer Hela cell line. Methods Eukaryotic expression vector of human caveolin-1 gene was introduced into Hela cells by Lipofectamine. The clones stably overexpressed caveolin-1 were identiffed by RT-PCR, immunofluorescence cell staining techniques and Westernblotting. Cells proliferation viabihty was tested by MTT assay, and flow cytometry was used to assay the cell cycle and apoptosis, and the relative phosphorylation level of extracellular regulated protein kinases (Erk1/2) were detected by Westernblotting. Results The clones stably overexpressed caveolin-1 were obtained. Compared with the parental Hela cells, the tranfected cells exhibited a slower rate of growth. FAGS analysis results revealed that overexpression of caveolin-1 resulted in the cell cycle arrest in the G0/G1 [ ( 68. 04 ± 2. 57 ) % vs ( 53.41 ±1.01)%] phase and increased the apoptotic cell fraction[ (19. 18 ±2.20)% vs (5.63 ±0.55)%, P <0. 05 ]. Western blotting results showed that overexpression of caveolin-1 reduced the phosphorylation of Erk1/2(0.28 ±0.05 vs 0.81 ±0.07, P <0.05). Conclusions Overexpression of caveolin-1 suppressed the growth of Hela cells and induced apoptosis, down-regulation of Erk1/2 phosphorylation might be involved in its mechanism.

BACKGROUND:The effects of both conservative and traditional open reduction and internal fixation are dissatisfactory in the treatment of thoracolumbar fractures, however, minimal-invasive percutaneous pedicle screw-rod systems provide a new available method.
OBJECTIVE:To investigate the clinical effect of percutaneous pedicle screw fixation using Sextant minimal-invasive system in the treatment of thoracolumbar fractures.
METHODS:A total of 55 patients, who had undergone percutaneous pedicle screw fixation using Sextant system (25 patients) or open pedicle screw fixation (30 patients) for single-level vertebral body compression fractures in Department of Orthopedics, Renmin Hospital of Wuhan University from February 2011 to January 2013, were enrol ed in this study. They showed no neurological signs and symptoms. The operative time, intraoperablood loss, postoperative drainage amount, length of hospital stay, pre-and post-operative Cobb angle and anterior vertebral body height ratio were recorded and compared between two groups.
RESULTS AND CONCLUSION:Except two patients in open pedicle screw fixation group were lost after discharge, al other patients were fol owed up for 8-14 months. There were significant differences in operative time, intraoperative blood loss, postoperative drainage amount and length of hospital stay between two groups (P=0.000 0). The post-operative Cobb angle was significantly lower while anterior vertebral body height ratio was significantly higher at one week than those before fixation in two groups (P=0.000 0). No significant difference was found in correction loss between two groups at 8 months after operation. Experimental findings indicate that, percutaneous pedicle screw fixation using Sextant system has a satisfactory outcome in the treatment of thoracolumbar fractures. However, understanding the correct indications is very important for clinical application.
