[Establishment and experimental study of alveolar preservation before dental implantation in Beagle dogs].

Purpose: To establish the model of alveolar ridge preservation after tooth extraction for dental implant replacement, and to observe the effect of tissue engineered bone on osseointegration.

Methods: Isolated BMSCs were expanded and osteogenically induced in vitro. The tissue engineering complex was constructed with BMSCs/A-PCPC in vitro.

A water-alcohol extract of Citrus grandis whole fruits has beneficial metabolic effects in the obese Zucker rats fed with high fat/high cholesterol diet.

Epidemiological studies suggest that citrus fruits and compounds such as flavonoids, limonoids and pectins have health promoting effects. Our aim was to study the effects of Citrus grandis (L.) Osbeck var.

[Expression of NF-kappaB and COX-2 in tongue squamous cell carcinoma].

Purpose: To examine the expression of nuclear factor-kappaB (NF-kappaB) and cyclooxygenase-2 (COX-2) and their relationship in tongue squamous cell carcinoma (TSCC) and to evaluate their functions in the development and progression of TSCC.

Methods: The expression of NF-kappaB and COX-2 in 50 cases of TSCC was determined using SP immunohistochemical method. Data was statistically analyzed by Chi-square test with SPSS11.

[Quantitative analysis on Radix Salviae miltiorrhizae by NIR].

Objective: Rapid nondestructive determination of salvianolic acid B and tanshinone IIA in Radix Salviae Miltiorrhizae with near-infrared reflectance spectroscopy.

Method: A quantitive model was built up with near-infrared diffuse reflectance spectroscopy.

Results: The RMSEP in quantitative calibration model for salvianolic acid B and tanshinone IIA were 0.

Inhibition of rat vascular smooth muscle cell proliferation by extract of Ligusticum chuanxiong and Angelica sinensis.

Ligusticum chuanxiong (LC) and Angelica sinensis (AS) have been widely used as traditional Chinese medicine to treat some pathological settings such as atherosclerosis and hypertension. The aim of this paper is to determine the effects of the extract of LC and AS (ELCAS) on serum-induced vascular smooth muscle cell (VSMC) proliferation, cell cycle and nitric oxide production. The results show that ELCAS significantly inhibited proliferation and protein synthesis of VSMC in a dose and time dependent manner.

Protective effect of Ligusticum chuanxiong and Angelica sinensis on endothelial cell damage induced by hydrogen peroxide.

Ligusticum chuanxiong and Angelica sinensis have been widely used in traditional Chinese medicine to treat some pathological settings such as atherosclerosis and hypertension. We determined the protective effect of the extract of Ligusticum chuanxiong and Angelica sinensis (ELCAS) on human umbilical vein endothelial cells (ECV304) damage induced by hydrogen peroxide. ECV304 cells were pre-treated with ELCAS and exposed to 5 mM hydrogen peroxide.
