Basic fibroblast growth factor(bFGF) is one of the most important factors for wounds healing.BFGF promotes healing of bone fracture by regulating cell proliferation and differentiation of bone tissues,increasing local bone density,and accelerating local angiogenesis.With the progression of bFGF research,more and more attention will be paid to bone repair function of bFGF in bone tissue engineering.

The capacity to generate iaterleukin-2(IL-2)of,and autologous rosette forming cel-ls(ARFC)ratio of 46 cancer patients(29 nasopharygeal carcinoma,11 lymphoma and6 leukemia)were studied.A several important things have been found as follows:(1)There was a significant decrease in capacity of cancer patient peripheral blood mono-nuclear cells(PBMC)to generate IL-2 after being stimulated for 48 hr by PHA(18%,whencompared to controls;P0.05);(3)The cancer patient plasma could markedly inhibit IL-2 generation,but control plasmadid not.This result suggested that the patient plasma contain immunosuppressive fact-or(s)which can block IL-2 generation;(4)ARFC ratio in cancerpatients was greatlylower than that of controls(10% and 22% respectively;P

Objective To investigate the effects of GSTT on expression of inflammatory molecule ICAM-1 and the infiltration of neutrophils in rats after myocardial ischemia/reperfusion (MI/R) injury. Methods A model of myocardial ischemia 45min followed by 2h reperfusion was made by reversibly ligating coronary left descending artery. 32 Sprague Dawley (SD) rats were divided randomly to 4 groups, ie: sham-operated group, model group, large and dosage of GSTT. HE staining was used to observe infiltrating neutophils. The activity of MPO was measured, too. Immunohistochemistry was used to determine ICAM-1 expression in myocardium. Results Light microscopy showed that the infiltration of neutrophils in both large and low dosage of GSTT group was less serious than that in model group. Both large and low dosage of GSTT significantly decreased MPO activity (P

Objective To investigate the effects of gross saponin from Tribulus terrestris (GSTT) on myocardial ischemia/reperfusion (MI/R) injury. Methods A model of myocardial MI/R injury of the myocardium was reproduced by ligation of left descending artery for 45min followed by releasing the ligation for 2 hours in rats. 64 SD rats were divided randomly to 4 groups, i.e. sham-operated group, model group, large and low dose of GSTT groups. HE staining was examined to assess myocardial pathological changes. TTC staining was used to determine myocardial infarction area. Serum contents of lactate dehydrogenase (LDH), creatine phosphokinase (CPK) and malondialdehyde (MDA) were also determined. Results Both large and low dose of GSTT improved myocardial pathological changes after ischemia/reperfusion. Large dose of GSTT reduced myocardial infarction area (P

Objective To investigate the preventive effects of total saponin from Tribulus terrestris (GSTT) on cardiomyocytes subjected to low oxygen tension and re-oxygenation injury in vitro. Methods First passage of cultured cardiomyocytes was subjected to hypoxia followed by oxygenatim. The cells were divided into 4 groups, namely normal group, injury group, and large and low dose of GSTT groups. The frequency of contraction, survival rate and release of myocardial enzymes were determined. The morphologic changes were observed with light and electron microscopy. Results Both large and low dose of GSTT significantly improved the survival rate of cardiomyocytes after hypoxia and re-oxygenation injury (P

To investigate the genotype distributions of PLA1/PLA2 polymorphism in Chinese Han population from Beijing and Hebei Province and to study the correlation between the platelet membrane glycoprotein IIIa polymorphism and coronary heart disease (CHD) or CHD with blood-stasis syndrome.

OBJECTIVE: To investigate the differential gene expression profiles in patients with blood stasis syndrome by oligonucleotide microarray technique. METHODS: Sixteen patients with blood stasis syndrome were divided into patients with coronary heart disease (CAD) (n=8) and non-CAD patients (n=8) by using coronary angiography. The sex- and age-matched eight healthy persons were enrolled as control group. Venous bloods were collected for extracting RNA. Test-3 chip was first employed to examine the quality of samples. Then the samples were hybridized with Affymetrix U133 Plus 2.0 array to compare the gene expression profiles among the three groups. Gene-array scanner and gene chip operating software were applied to screen hybridization signals and analyze gene expression respectively. Based on the comparison of the three groups of samples, the differential genes related with blood stasis syndrome were analyzed by Gene Ontology (GO) and pathway, and confirmed by real-time reverse transcription polymerase chain reaction (RT-PCR). RESULTS: Forty-eight differential genes were found being associated with blood stasis syndrome, including 26 up-regulated genes and 22 down-regulated genes. Five of the forty-eight genes (10.4%) were related to inflammatory reaction and immune response through the GO analysis. In the pathway analysis, five of ten significant pathways were referred to inflammation and immune response. The results of real-time RT-PCR proved the accuracy of the gene chip. CONCLUSION: Inflammatory- and immune-related genes have a remarkable predominance in blood stasis syndrome gene expression profiles, which may explain the function of inflammation and immune response in the occurrence and development of blood stasis syndrome.

Objective To investigate the effect of GSTT on the release of inflammatory molecules such as TNF-? and IL-1? in rats after ischemia/reperfusion injury. Methods An in vivo model of myocardial ischemia 45min followed by 2h reperfusion was made by reversibly ligating coronary left descending artery. 32 Sprague Dawley (SD) rats were divided randomly to 4 groups, ie: sham-operated group, model group, large and dosage of GSTT. TNF-? and IL-1? concentrations were examined by radioimmunoassay. Results Compared with model group, large dosage of GSTT significantly decreased the contents of TNF-? and IL-1?(P

Objective To investigate the effects of gross saponins from Tribulus terrestris L (GSTT) on myocardial apoptosis, and its related gene bcl-2 and bax expression after hypoxia/reoxygenation in cultured myocardial cells of neonatal rat. Methods After myocardial hypoxia/ reoxygenation model was established by culturing primary myocardial cell of neonatal rat in vivo. The myocardial cells were divided into four groups, the sham-operated group, model group, large- and low-dose of GSTT groups. The apoptotic rate of myocardial cells was determined by flow cytometry, and the expression of bcl-2 and bax was detected by using immuno-histochemical method. Results Both large- and low- dose of GSTT could significantly decrease the apoptotic rate (P
