2.Regulating effect of Tongxinluo on HIF-1α,VEGF generated by the human brain microvascular endothelial cells induced by β-amyloid1-42
Chinese Pharmacological Bulletin 2010;26(1):124-127
Aim To study the regulating effect of Tongxinluo on HIF-1α,VEGF that Generated by the Human brain microvascular endothelial cells induced by β-amyloid 1-42.Methods Human brain microvascular endothelial cells were pre-incubated for 4h by Tongxinluo, then injured by β-amyloid 1-42.VEGF protein and HIF-1α were detected by Western blot.Result In the Aβ treated Human brain microvascular endothelial cells,viable cells decreased.The expression of VEGF was Reduced, and HIF-1α elevated. After the cells were treated with Tongxinluo, all the above indexes were improved.Conclusion Tongxinluo can enhance the VEGF protein expressions by the HIF-1α and protect the Human brain microvascular endothelial cells.

Objective To explore the effects of different swimming training intensities on the expression of glial fibrillary acidic protein (GFAP) and basic fibroblast growth factor (bFGF) around a cerebral infarct. Methods The intraluminal thread method was applied to establish left middle cerebral artery occlusion (MCAO) for 2 h in 180 rats.They were then reperfused for 3,7 and 14 days.The rats were divided into four groups ( Ⅰ -Ⅳ) according to the intensity of the swimming training they were required to do,plus a control group and a sham operation group.The rats in training group Ⅰ swam 5 min,once daily; group Ⅱ trained for 5 min twice daily; group Ⅲ swam for 10 min once daily and group Ⅳ trained for 10 min twice daily.Neurological function was evaluated using Bederson's test,the cerebral infarction volume was calculated by tripeny tetrazolium chloride (TTC) staining.The expression of GFAP and bFGF around the infract were detected using immunohistochemistry.ResultsThe average Bederson scores of the exercise training groups on the 7th and 14th days were significantly lower than that of the control group.The infarction volumes of each exercise training group were significantly lower than that of the control group,and cells positive for GFAP and bFGF in all training groups were significantly more numerous on the 3th,7th and 14th day after MCAO,especially in training group Ⅳ.Conclusion Intensive exercise can adjust the expression of GFAP and bFGF and promote the repair of brain damage after cerebral ischemia and reperfusion.

OBJECTIVE: To establish a RP-HPLC method for the simultaneous determination of Protocatechuic acid and Protocatechuic aldehyde in Fuxuekang granules. METHODS: The chromatography was carried on Achirom Bond-1 C18 column(250 mm?4.6 mm,5 ?m). The mobile phase was composed of methanol - water (20∶80,pH=2.80 adjusted by glacial acetic acid) at a flow rate of 1.0 mL?min-1. The detection wavelengths were programmed at 256 nm for Protocatechuic acid and at 280 nm for Protocatechuic aldehyde. RESULTS: The linear ranges for Protocatechuic acid and Protocatechuic aldehyde were 5.49~73.22 ?g?mL-1(r=0.999 9) and 4.81~64.13 ?g?mL-1(r=0.999 9), respectively, and their average recoveries were 96.86%(RSD=2.52%,n=9) and 97.55%(RSD=3.82%,n=9) respectively. CONCLUSION: The method is simple, sensitive, and reproducible, and it is applicable for the quality control of Fuxuekang granules.

In the present study the effects of electroacupuncture (EA) on substance P (SP), somatostatin (SOM) and serotonin (5-HT) immunoreactivity (IR) of APUD cells and nerve fibers in the pylorus and in the skin of "Zusanli" acupo- int of rats were studied using immunohistochemical technique. Forty rats were divided into 20 pairs, one of each pair for EA (bilateral "Zusanli" acupuncture for 20 min), the other one for control. After EA the pain threshold was mark- edly increased(P

In order to improve the technique for histochemical demonstration of the different lymphocyte patterns by alpha-naphthyl acetate esterase (ANAE) activity from a single microscopic slide, 10 kinds of comparative experiments were performed. The results showed as follows. The peripheral blood mononuclear cells first fixed in 0.4% glutaldehyde and postfixed in 15% formol calcium gave the best effect on preserving the enzyme activity and on connterstaning of the leucocyte nuclei. During formol calcium fixation, the erythrocytes were dissolved from the diluted blood film with PBS more easily than from the blood smear without any dilution. The lymphocytes were distributed more uniformly and densely in the former specimen than in the latter. When incubated with 0.5 mg alpha-naphthyl acetate/ml medium in hexoazotized pararosaniline for 1(1/2)~2 hrs at 37℃, the distinct ANAE patterns of circulating lymphocytes were more readily identified.In 28 healthy adults the differential counts of the lymphocyte ANAE patterns from the diluted blood specimen was similar to those found from the specimen of isolated lymphocytes. The focal pattern was about 56%, the diffuse pattern about 25% and the negative pattern about 19%; while the isolated lymphocyte specimen was compared with the diluted blood film from the same individuals, the focal pattern was decreased insignificantly, the diffuse pattern increased and the negative pattern decreased significantly.

Objective To explore the effects of vitamin C and niacinamide on the growth and differentiation of human primary cultured keratinocytes.Methods Normal human foreskin was used in this study.The epidermis was separated enzymatically from the dermis by thermolysin,and keratinocytes were isolated from the epidermis by digestion with trypsin plus EDTA.The single keratinocytes were cultured with undedying NIH-3T3 cells as feeder cells in a complete medium supplied with 50 mg/L (vitamin C group),niacinamide of 400 μmol/L(niacinamide group)or vehicle(control group).Immunocytochemistry and immunodot blot were performed using monoclonal antibodies directed against C-myc,cyclin D1,filaggrin and involucrin.Results The colony number was highest in vitamin C group,followed by the control group and niacinamide group,and the colony morphology in vitamin C group was similar to that in the control group,but distinct from that in the niacinamide group.A significant increase was noticed in the expression of C-myc,cyclin D1,filaggrin and involucrin in vitamin C-treated keratinocytes compared with the control keratinocytes(all P<0.05);however,in niacinamide-treated keratinocytes,the expression of filaggrin was significantly enhanced(P<0.01),that of involucrin remained unchanged(P>0.05),while that of C-myc was depressed(P<0.05).Conclusions These results demonstrate that vitamin C has a favorable effect on both the growth and differentiation of human keratinocytes,while niacinamide seems to only promote the differentiation but attenuate the growth of human keratinocytes.

[ ABSTRACT] AIM:To investigate the damage in human umbilical vein endothelial cells ( HUVECs) induced by recombinant soluble human CD40 ligand (rshCD40L).METHODS:The cultured HUVECs were treated with rshCD40L for 12 h.The survival activity of the HUVECs was observed by MTS assay.The expression of E-selectin, intercellular ad-hesion molecule (ICAM)-1, tissue factor (TF) and tissue factor pathway inhibitor (TFPI) was measured by ELISA.The activity of superoxide dismutase ( SOD) and the level of malondialdehyde ( MDA) were detected by the methods of thibabi-turic acid (TBA) .RESULTS:Compared with normal group, different concentrations of rshCD40L (0.5, 1, 2, 3 mg/L) had no obvious effect on the survival activity of the HUVECs (P>0.05).rshCD40L at concentration of 0.5 mg/L promo-ted the secretion of E-selectin, sICAM-1, TF and TFPI in the HUVECs (P<0.01).rshCD40L at concentration of 0.5 mg/L also increased MDA content and reduced the activity of SOD in the HUVECs (P<0.05).CONCLUSION:0.5~3mg/L rshCD40L has no obvious effect on endothelial cell survival, but already causes endothelial dysfunction by increas-ing endothelial inflammation and exogenous coagulation reaction, inducing lipid peroxides injury and reducing antioxidant capacity.
