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.

Oridonin is ent-kaurane diterpenoid and is one of the efficacious component of Rabdosia Rubesecens ( Hemel. ) Hara in Henan province. In this experiment, the effects of Oridonin on hemody-namics of anaesthetized rabbits were studied. Hemodynamics effects of Oridonin (3.0 mg, 10.0mg/kg iv)were noticed. LVSP, ?dP/dt_max, Vpm, Lo, HR, SBP, DBF were decreased. t-dP/dt_max was increased. LVEDP did not changed. Oridonin decreased DBP more than SBP, it is suggested that Oridonin. may reduce vascular smooth muscle tone.

Objective To investigate the relationship of the lymphangiogenesis and lymphatic metastasis by observing the expression of proliferating cell nuclear antigen in the hamster tongue cancer development and analyzing the correlations of lymph vessel density (LVD), lymphatic vessel area (LVA) and malignance or lymphatic metastasis of tongue cancer cells. Methods Forty_two hamster tongue cancer models were induced by painting 1.5% 7,12-dimethylben(a) anthracene (DMBA) acetone solution after scratching, 7 models were sacrificed every two weeks. The pathological changes of tongue cancer were determined by the HE staining. The lymphatic hyperplasia was determined by PCNA and Desmoplakin(DP I +Ⅱ) Immunohistochemical double staining. The tumors and lymphatic endothelial cell proliferation index (proliferation index, PI), lymphatic vessel density (LVD) and lymphatic vessel area (LVA) were measured and statistically analyzed. Results The oncogenesis of tongue was divided into three stages: atypical hyperplasia, carcinoma in situ and early invasive stage;atypical hyperplasia group:PI (91.55), LVA (7570.23), LVD (2.50);carcinoma in situ group: PI (113.36), LVA (12105.45), LVD (3.73);early invasive group: PI (124.67), LVA (14524.33), LVD (5.33). The PI, LVA and LVD were compared among groups above (P<0.05), and the correlation of PI with LVA and LVD was positive (P<0.05);Lymphatic metastasis group:PI (130.50), LVA (15430.67), LVD (6.17), non lymphatic metastasis group:PI (113), LVA (12711.67), LVD (3.67), the PI, LVA and LVD were compared between the two groups above (P<0.05).Conclusion With the development of hamster tongue cancer, lymphatic endothelial cell proliferation activity increased, suggesting that the lymphangiogenesis existed in the tongue carcinogenesis process;the values of the LVD and LVA increased in the hamster tongue cancer development, which was positively correlated with the cancer cell malignance and lymphatic metastasis.

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: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.
