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 The aim of this study was to observe the growth difference and expression of cytochrome C of skin hair follicles in neonatal mice .Methods The morphology of different skin hair follicles of neonatal mice ( postnatal day 1-9)were observed by HE staining histology and cytochrome C was detected by immunohistochemistry .Results The skin hair follicles in different parts of neonatal mice showed differences not only in morphology but also in developmental pe -riods.Hair follicle growth in the back and tail skin had a nonlinear and growing period .After the nonlinear and growing pe-riod they began to grow rapidly .The tail development was slightly slower than that on the back .The hair follicles of vibris-sae were very special , and started to develop without a stable period .Conclusions The results of morphological observa-tion and cytochrome C immunohistochemistry demonstrate that differences exist in the hair follicle morphology and develop -mental times in the skin of different parts of the body in neonatal mice .

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.

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.

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.
