Aim To study the regulating effect of Tongxinluo on HIF-1?,VEGF that Generated by the Human brain microvascular endothelial cells induced by ?-amyloid 1-42. Methods Human brain microvascular endothelial cells were pre-incubated for 4h by Tongxinluo,then injured by ?-amyloid 1-42. VEGF protein and HIF-1? were detected by Western blot. Result In the A? treated Human brain microvascular endothelial cells,viable cells decreased. The expression of VEGF was Reduced,and HIF-1? 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-1? 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.

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.

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

0.05). But there have extremely significant between the normal and abnormal groups.(P0.05) , but the stunting group was extremely significant with the other three groups (P

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.

Objective To investigate the variation of interleukin-6 ( IL-6 ) , vascular endothelial growth factor(VEGF),E-selectin and intercellular adhesion molecule-1(ICAM-1)in children with sepsis and the clinical significance. Methods This was a prospective and control study. Thirty-two children diagnosed as sepsis in PICU from December 2008 to December 2009 served as the sepsis group. According to whether there was a shock, sepsis group were divided into shock subgroup and no shock subgroup. Fifteen healthy children served as control group. The serum levels of IL-6,VEGF,E-selectin and ICAM-1 were detected with enzyme linked immunosorbent assay. Results The serum level of IL-6 was 65. 00(30. 49~237. 14) ng/L in shock subgroup and 48. 68(30. 25~75. 00) ng/L in no shock subgroup,which were significantly higher than that in control group[0. 80(0. 60 ~1. 00) ng/L](P<0. 05). There was no significant difference between shock subgroup and no shock subgroup. The serum levels of VEGF and E-selectin showed no significant differences among the three groups. The serum level of ICAM-1 was 998. 72(666. 93~1 526. 44) ng/ml in shock subgroup,and 925. 71(683. 53~1 225. 12) ng/ml in no shok subgroup,which were significantly high-er than that in control group[660. 59(525. 48~685. 47) ng/ml]. Compared with those who survived in sep-sis group,the serum levels of VEGF and E-selectin in the died children with sepsis showed no significant difference,but IL-6 and ICAM-1 significantly increased(P<0. 05). Conclusion IL-6 and ICAM-1 increase greatly and accentuate inflammation in septic patients,the changes of which may help to determine the prog-nosis of sepsis.

AIM:To investigate COX-2 and iNOS protein contents and their interaction in vascular endothelium injury of rats with deficiency of vital energy or qi stagnation,and the prevetion and treatment of Tongxinluo.METHODS:The model of vascular endothelium injury of rats with deficiency of vital energy or qi stagnation was established by using high L-Methionine,with load-carrying swimming or being fastened respectively.Western blotting was used to analyze protein contents of COX-2 and iNOS,co-immunoprecipitation and laser confocal microscopy were used to analyze the interaction between COX-2 and iNOS.Optical microscope and electronic microscope were used to evaluate pathological changes in vascular endothelium.RESULTS:The protein contents of COX-2 and iNOS,and their interaction increased significantly in deficiency of vital energy group and qi stagnation group,in accord with injury of vascular endothelium.Compared with deficiency of vital energy group and qi stagnation group respectively,their protein contents decreased and their interaction was weakened in Tongxinluo groups.CONCLUSION:When protein contents of COX-2 and iNOS increase and their interaction enhance after vascular endothelium injury of rats with deficiency of vital energy or qi stagnation,initiate exacerbations,Tongxinluo could attenuate the alterations and protect vascular endothelium from injury.
