BACKGROUND: How to choose traditional Chinese remedy to treat cerebrovascular disease, not only improving the brain blood supply but also not affecting the blood pressure and heart rate, has been a promising research.OBJECTIVE: To study the role of yangyintongnao granule on average blood pressure and heart rate in anaesthetized dog.DESIGN: Complete grouping design and randomized controlled study based on hybrid dog.SETTING: Department of Anesthesiology, Xijing Hospital, Fourth Military Medical University of Chinese PLA and Department of Pharmacology, Faculty of Preclinical Medicine, Fourth Military Medical University of Chinese PLA MATERIALS: The experiment had finished by Cardiovascular Laboratory of Physiology Department in the Fourth Military Medical University of Chinese PLA from March to June 2003. Totally 23 healthy hybrid dogs in either sex were selected. These dogs were divided randomly into 4 groups: high dose group of yangyintongnao( n = 8), moderate dose group of yangyintongnao ( n = 6), low dose group of yangyintongnao( n = 5) and saline group( n = 4).METHODS: Anesthetic dogs in high, moderate and low dose group of yangyintongnao granule were given different doses of yangyintongnao granule: 2 g/kg, 1 g/kg and 0. 5 g/kg respectively. All doses of drug were calculated based on the body mass of dogs, and the drugs were dissolved in 100 mL saline and given through the gastric canal. Dogs in saline group were perfused with equal saline. Aortic average blood pressure was measured by femoral artery intubation via a piezometric transducer. Heart rate was obtained from R-R intervals of a standard Ⅱ lead of electrocardiograph(ECG). The mean blood pressure and heart rate were recorded 0. 5, 1, 1.5, 2.0,3.0, 4. 0, 5.0, 6. 0 hours after treatment.MEAN OUTCOME MEASURES: The changes of blood pressure and heart rate at different time before and after medication.RESULTS: Totally 29 dogs were brought into the final analysis. Blood pressure: The mean blood pressure was reduced -5.4% to -6. 2% respectively in high dose group and moderate dose group after treatment. But in low dose group the average blood pressure sometimes increased sometimes decreased, mainly decreased. It increased by 6.6% ( P > 0. 05) and decreased by -4. 1% ( P > 0.05) at maximum. The average blood pressure in saline group changed by - 9.6% ( P > 0.05). Heart rate: The heart rate in high and medium dose group gradually reduced as time went on. It reduced by - 4. 4%, - 12.2% and - 9.5% respectively in high, moderate and low doses group. The change in each group was not statistically significant as the same in saline group( P > 0.05).CONCLUSION: Yangyintongnao granule has no significant influence on average blood pressure and heart rate.

Despite seminal studies in the 1920s by Warburg showing a characteristic metabolic pattern for tumors, cancer bioenergetics has otfen been relegated to the backwaters of cancer biology. Recent studies have shown that metabolism in the tumor tissue is far more complicated than we previously knew. Despite vigorous glycolysis, in fact, the tumor tissue still retains mitochondrial aerobic metabolism. Mitochondria is one of the main sites of the biosynthesis process of tumor cells. Recent studies revealed that abnormal fatty acid metabolism. Amino acid metabolism plays a key role in the tumorigenesis. The metabolic network in tumor cells was reprogrammed, leading to nutrition lfux reorganization and re-direction. Metabolism reprogramming in tumor cells facilitates the balance between the needs of energy supply and the synthesis of biological macromolecules. Targeting cell metabolism is not intended to interfere the energy supply of tumor cells but to affect the synthesis of metabolic rate, thereby inhibiting the proliferation of the tumor. hTe review focuses on the importance of metabolic reprogramming in tumor development and cancer therapy. We summarize what is currently known about metabolic reprogramming and establish a framework to understanding its contribution to the altered metabolism of cancer cells.

Objective To assess isehemic myocardial regional function of different coronary atherosclerosis using velocity vector imaging(VVI).Methods Two-dimensional images of apical four-,two-chamber and long-axis view were obtained in 50 patients with coronary artery disease.All segments of the left ventricle were divided into 5 groups:group 0 with no coronary artery stenosis,group 1 with stenosis<50%,group 2 with stenosis 50%to 74%,group 3 with stenosis 75%to 99%and group 4 with a completely occluded coronary artery.The segmental myocardial systolic peak strain(ε),systolic strain rate(SRs),early diastolic strain rate(SRe),late diastolic strain rate(SRa)and their ratio(SRe/SRa)were analyzed with VVI offline software.Results①Compared with group 0,SRe and SRe/SRa of group 1,SRs,SRe,SRe/SRa of group 2~4,εof group 2 and group 4 decreased significantly(P<0.05).②In the comparison of four ischemic groups,ε,SRe,SRa of group 3 were markedly higher than those of group 2,while ε,SRs,SRa of group 2 were lower than those of group 1(P<0.05);for group 4,ε,SRs,SRe were lower than those of group 1,SRe was lower than that of group 2,and ε,SRs,SRe were lower than those of group 3(P<0.05).ConclusionsIn the process of coronary atherosclerosis,myocardial diastolic and systolic dysfunction occurred early and orderly,and has a bidirectional change:decreased firstly,then increased and decreased at last.

Objective Through investigating the effect of mesenchymal stem cells (MSCs) on the expression of yon Willebrand factor (vWF) and soluble thrumbomodulin (sTM) of vascular endothelial cells stimulated by serum of systemic lupus erythematosus (SLE) patients to discuss the repairing effect of MSCs on injured endothelium of SLE patients.Methods When human umbilical vein endothelial cell strain ECV-304 was co-cultivated with serum of SLE patients in vitro for twelve hours in order to induce endothelial cells injury,then MSCs were seeded for three days.Enzyme linked immunosorbent assay (ELISA) was used to detect the expression of vWF and sTM in the supernatant.Results When ECV-304 was stimulated by serum of SLE patients,the expression of vWF and sTM in the supernatant was significantly higher than that in the groups not stimulated by serum of SLE patients;When MSCs were seeded ,the expression of vWF in the Lupus serum stimulated group in which MSCs were seeded was significantly lower than that in the lupus serum stimulated group in which MSCs were not seeded,but the expression of sTM between the lupus serum stimulated group which MSCs were seeded and the lupus serum stimulated group in which MSCs were not seeded was not significantly deviatied.Conclusion Serum of lupus patients at active stage can cause injure vascular endothelial cells.MSCs can downregulate the expression of vWF of vascular endothelial cells.These suggest it may participate in the repairing of injured vascular endothelium of SLE patients.

This study was aimed to observe the promotion effect of wound healing retention enema for postoperative anal fistula by modifiedWu-Wei Xiao-Du(WWXD) decoction, in order to explore its mechanism. A total of 60 patients who met the inclusion criteria were randomly divided into the treatment group and control group, with 30 cases in each group. Patients in both groups were diagnosed as simple low anal fistula and treated with low anal fistula incision. The retention enema of 30 mL modified WWXD decoction or complexHuang-Bai fluid were given once a day for postoperative dressing changes. Detailed observations and scores were made on wound exudate, color, and itching around the anus. The comparisons were made on carrion off time, new epithelium time, rate of wound-reducing, wound healing time, and the total clinical efficacy 21 days after operation. The results showed that the wound exudate on the 7th and 14th postoperative day was better than that of the control group. There was no significant difference on the 21st day between two groups. The wound color of the treatment group was better than that of the control group on the 7th and 14th postoperative day. The itching around anus of the treatment group was better than that of the control group on the 7th, 14th and 21st postoperative day. The carrion wound off time and new epithelium time of the treatment group were earlier than that of the control group. There was no significant difference on the rate of wound-reducing. There were no significant differences on the total clinical efficacy 21 days after operation as well as the total average healing time of both groups. It was concluded that modified WWXD decoction can shorten the inflammation phase, reduce the wound exudate and itching, promote early carrion fall and as well as the wound healing.
