1.5,2.0,and 2.5 mm/day)was performed on 20 goats and 20 rabbits.It was found that a relatively slow lengthening rate of 1mm/day was better since it induced less tissue reactions and quicker bony regeneration and created more dense and more mature bony trabeculae in the lengthened zone than the other 3 rates.In addition,it was also found the new bone formation in the lengthened zone of the proximal metaphysis of the tibia proceeded quickly and both intramem-branous and endochondral ossifications contributed to the bone healing process with the former in predominance.

Objective To investigate the effect of Xuebi-jing injection on the change of the serum high-sensitivity C-reactive protein (hs-CRP) in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD). Methods 86 patients with AECOPD were enrolled in this study, who was randomly divided into a control group (43 cases)and a treatment group (43 cases). Both treatment group and control group were given conventional therapy. On this basis, Xuebi-jing injection was added to the treatment group. Hs-CRP, blood gas analysis, blood cell count and severity of illness score (acute physiological and chronic health evaluation Ⅱ, APACHE Ⅱ) were monitored before and 5 days after treatment. Results There was no obvious difference of hs-CRP levels between two groups before treatment. Hs-CRP was decreased in both groups after the treatment, while the treatment group showed an obvious decrease compared with the control group (t＝5.3302,P＜0.01). Blood gas analysis, blood cecount, APACHE Ⅱ scores were improved after the treatment in both groups, while the improvement in treatment group showed obvious difference than the control group (t＝13.5089、26.3077 、13.4053,P＜0.01). Conclusion The conventional therapy plus Xuebi-jing injectiong for AECOPD can improve serum hs-CRP levels and improve the efficacy of AECOPD .

BACKGROUND: Ambulatory blood pressure monitoring can sensitively and objectively reflect blood pressure level, which is closely related to target organ damage and disease prognosis. In hypertension, vascular endothelial damage is the most common lesion to target organs. There is little known about how ambulatory pulse pressure correlates to large artery elasticity and vascular endothelial function. OBJECTIVE: To investigate changes of large artery elasticity and of vascular endothelial function in patients with primary hypertension using an automatic pulse wave velocity determinator and ultrasound techniques, and to analyze the correlation of ambulatory pulse pressure to large artery elasticity and vascular endothelial function.DESIGN: A non-randomized concurrent control clinical observation. SETTING: Diagnosis and Treatment Center for Coronary Heart Disease, the 305 Hospital of Chinese PLA. PARTICIPANTS: A total of 156 inpatients and/or outpatients, who were recently confirmed with primary hypertension, were recruited for this study between June 2005 and April 2007. Patients consisted of 114 males and 42 females. All patients averaged 56 ± 4 years of age (range: 40-75). Inclusive criteria: Corresponding to diagnostic standards for preventing and treating hypertension instituted in 2004 by Chinese scholars. Confirmed as primary hypertension within 1 month. Not receiving any blood pressure lowering, hypolipidemic or nitrate-like drug treatments. Written informed consents for laboratory measurements were obtained from all subjects. The study was approved by the hospital's Ethics Committee. METHODS: According to the mean pulse pressure over 24 hours, all patients were assigned into 3 groups: Group A (mean pulse pressure ＜ 40 mm Hg, n=92), group B (40 mm Hg ≤ mean pulse pressure ＜ 60 mm Hg, n=39) and group C (mean pulse pressure ＞ 60 mm Hg, n=25). In each group, daytime pulse pressure and night-time pulse pressure, as well as 24-hour mean pulse pressure were measured using a non-invasive portable ambulatory blood pressure monitor (ABPM-04, Meditech Inc, USA). Carotid-femoral and carotid-radial arterial pulse wave velocities were measured using an automatic pulse wave velocity determinator to evaluate large artery dilation. Blood flow mediated and nitroglycerin-dependent dilatation of the brachial artery was determined using a high-resolution ultrasound technique to evaluate vascular endothelial function. MAIN OUTCOME MEASURES: Correlations of ambulatory pulse pressure to large artery dilation and arterial endothelial function. RESULTS: All 156 patients were included in the final analysis. Correlation of ambulatory pulse pressure to large artery dilation: Carotid-femoral arterial pulse wave velocity was significantly positively correlated to daytime pulse pressure, night-time pulse pressure and 24-hour mean pulse pressure, with coefficient of partial correlation being 0.310, 0.281 and 0.303, respectively, P ＜ 0.01). There were no significant correlations of carotid-radial arterial pulse wave velocity to daytime pulse pressure, night-time pulse pressure or 24-hour pulse pressure (P ＞ 0.05). Correlation of ambulatory pulse pressure to arterial endothelial function: There was a linear relationship between ambulatory pulse pressure and blood flow-mediated blood vessel dilatation values. Linear correlation analysis was performed, taking ambulatory pulse pressure as an independent variable, and endothelial-dependent dilatation as a dependent variable. Results demonstrated that blood flow-mediated blood vessel dilatation was significantly negatively correlated to daytime pulse pressure, night-time pulse pressure and 24- hour mean pulse pressure (r = -0.684, -0.597, -0.668, P ＜ 0.01). There was no correlation of ambulatory pulse pressure to non-endothelial-dependent blood vessel dilatation. CONCLUSION: Ambulatory pulse pressure increase is closely related to large artery elasticity decrease and injury to endothelial function in patients with primary hypertension.

Objective To investigate the influence of different doses and courses of cigarette smoking on the expression of ICAM-1 mRNA, ICAM-1 in rats' cerebral vascular endothelial cells and volumes of cerebral infartion.Methods 105 male Wistar rats(weight 210～220 g) were randomly grouped into long-term massive(20 cigarettes/d,75 d), short-term massive(20 cigarettes/d,30 d), long-term trifle (8 cigarettes/d, 75 d), anti-smoking(20 cigarettes/d, 30 d, denying 45 d)and normal control(no smoking). In situ hybridization, immunohistochemistry were used to determine the expression of ICAM-1 mRNA, ICAM-1 in rat's cerebral vascular endothelial cells (VECs).The VEC's structures were observed by electronic microscope. Left middle cerebral artery occlusion model was established and pathologic image analyzing system were used to determine the ratio of the volume of infarction in hemisphere of the same side. Results On contrast to normal controls, the expression of ICAM-1mRNA, ICAM-1 and the volume of infarction were increased in smoking(P

Objective To investigate the effects of high density lipoprotein (HDL) on thrombin-activated platelet al-pha-granulemembrane protein (CD62P) and lysosome intact membrane protein (CD63) expressions in vitro. Methods The equivalent volume of washed platelets prepared by hand was preincubated with HDL (1 g/L) in 37℃water for 15 minutes, which was then stimulated with different concentrations of thrombin (0.5 U/mL, 1 U/mL and 10 U/mL) for 10 minutes in wa-ter of 37℃. Meanwhile another three groups of washed platelets were incubated with thrombin (0.5 U/mL, 1 U/mL and 10 U/mL) for 10 minutes, respectively. The CD62P and CD63 from each sample were analyzed by flow cytometry (FCM). Results The CD62P positive rates of HDL-preincubated groups were significantly lower than those of different concentrations of thrombin groups (0.5 U/mL,1 U/mL and 10 U/mL) in the absence of HDL (11.55%± 1.34% vs 18.14%± 1.50%, 17.19%± 0.17% vs 26.24%± 0.77% and 19.79%± 0.32% vs 80.38%± 5.66%,P ＜ 0.01). Meanwhile, The CD63 positive rates of HDL-preincubated groups were also significantly lower than those of thrombin-treated (0.5 U/mL, 1 U/mL and 10 U/mL) groups without HDL, namely,2.92%±0.22%vs 8.09%±0.48%(P＜0.001), 4.20%±0.98%vs 14.15%±1.39%(P＜0.001) and 5.12%± 0.09% vs 24.48%± 1.71%(P ＜ 0.01). Conclusion HDL inhibits the expression of CD62P and CD63 on throm-bin-stimulated platelets in vitro.

Objective To determine the expression and clinical value of neuropilin-1 (NRP-1) in hepatocellular carcinoma (HCC).Methods One hundred and fifty-one cases of HCC tissues and 89 cases of healthy liver tissues were chosen to compare the expression of NRP-1 by immunohistochemistry.Then the relationships between different clinical factors and the expression of NRP-1 were analyzed by univariate and multivariate statistical analysis.Moreover,the survival rates were compared by survival analysis between different expressions of NRP-1 in HCC patients.Results Eleven cases were lost to follow-up or died for non HCC disease,and the effective cases in the final study were 140 cases.The positive expression rates of NRP-1 in HCC and normal liver tissues were 65.00％ and 35.96％ respectively,and the difference was statistically significant (x2 =18.843,P ＜0.001).According to the expression level of NRP-1,140 patients with HCC were divided into negative expression group (n =49) and positive expression group (n =91).Univariate analysis showed that the expression of NRP-1 in HCC was correlated with tumor number (x2 =8.025,P =0.005),TNM stage (x2 =26.467,P ＜ 0.001),differentiation degree (x2 =15.296,P ＜ 0.001),portal vein invasion (x2 =9.054,P =0.003) and hepatic vein invasion (x2 =5.928,P =0.015).Multivariate statistical analysis showed that TNM stage (OR =1.392,95％ CI:1.121-1.730,x2 =8.950,P =0.003),differentiation degree (OR =1.469,95％ CI:1.102-1.958,x2 =6.862,P =0.009),portal vein invasion (OR =1.829,95％ CI:1.157-2.893,x2 =6.665,P =0.010) and hepatic vein invasion (OR =2.161,95％ CI:1.172-3.987,x2 =6.084,P =0.014) were important factors for NRP-1 expression.The median survival time of NRP-1 negative HCC patients was significantly longer than that of positive group (44 months vs.23 months),and the difference was statistically significant (x2 =21.922,P ＜0.001).Conclusion NRP-1 is over-expression in HCC tissue and related to the malignant progress of HCC,and this suggests poor prognosis in patients with HCC.
