EPA could increase tmTNF expression levels in time- and dose-dependant manners. Conclusion tmTNF-? expression vector regulated by n-3 PUFA is successfully constructed.

Objective To study the protection and mechanism of co-administration of vitamin E with coenzyme Q10(CoQ10) to valproate-associated hepatotoxicity in infantal rats.Methods The rat models were established by oral administration of valproic acid(VPA) in ablactation(21 days) Wistar rats,at doses of 500 mg/(kg?d) during 30 days,other groups received the same amount of VPA with phemobarbitone(PB) and co-administration with vitamin E and CoQ10.The changes of liver cell morphology and the blood coagulation test,as well as the contents of succinic dehydrogenase(SDH),cytochrome oxidase(CCO),cytochrome,the levels of glutothione(GSH) and malondial dehyde(MDA) in rat liver mitochondria were detected by chromatometry,HPLC,Oil-Red-O staining and electron microscope,respectively.Results 1.Average content of cytochrome aa3 in liver mitochondria of infantal rats were reduced by 58.80% and(61.80%) because of administration of VPA and VPA added with PB.The protection against the loss of cytochrome aa3 by coadministration of VitE and CoQ10 was obvious.As for activities of SDH and CCO,which affected by VPA and VPA added with PB in rats,were significantly lowered compared with control group(P

The survey of traditional knowledge related to Chinese materia medica resources is the important component and one of the innovative aspects of the fourth national survey of the Chinese materia medica resources. China has rich traditional knowledge of traditional Chinese medicine (TCM) and the comprehensive investigation of TCM traditional knowledge aims to promote conservation and sustainable use of Chinese materia medica resources. Building upon the field work of pilot investigations, this paper introduces the essential procedures and key methods for conducting the survey of traditional knowledge related to Chinese materia medica resources. The essential procedures are as follows. First is the preparation phrase. It is important to review all relevant literature and provide training to the survey teams so that they have clear understanding of the concept of traditional knowledge and master key survey methods. Second is the field investigation phrase. When conducting field investigations, survey teams should identify the traditional knowledge holders by using the 'snowball method', record the traditional knowledge after obtaining prior informed concerned from the traditional knowledge holders. Researchers should fill out the survey forms provided by the Technical Specification of the Fourth National Survey of Chinese Materia Medica Resources. Researchers should pay particular attention to the scope of traditional knowledge and the method of inheriting the knowledge, which are the key information for traditional knowledge holders and potential users to reach mutual agreed terms to achieve benefit sharing. Third is the data compilation and analysis phrase. Researchers should try to compile and edit the TCM traditional knowledge in accordance with intellectual property rights requirements so that the information collected through the national survey can serve as the basic data for the TCM traditional knowledge database. The key methods of the survey include regional division of Chinese materia medica resources, interview of key information holders and standardization of information.' In particular, using "snowball method" can effectively identify traditional knowledge holder in the targeted regions and ensuring traditional knowledge holders receiving prior informed concerned before sharing the information with researcher to make sure the rights of traditional knowledge holders are protected. Employing right survey methods is not only the key to obtain traditional knowledge related to Chinese materia medica resources, but also the pathway to fulfill the objectives of access and benefit sharing stipulated in Convention on Biological Resources. It will promote the legal protection of TCM traditional knowledge and conservation of TCM intangible, cultural heritage.

Objective To investigate the correlation between ~(18)F-fluorodeoxyglucose (FDG) uptake and hypoxia inducible factor1α (HIF-1α) level,microvessel density (MVD) in human gliomas.Methods ~(18)F-FDG PET scan was performed preoperatively in 41 patients with gliomas (including 23 highgrade and 18 low-grade tumors).The ratios of maximum standardized uptake value(SUV_(max))between tumor (T)and contralateral white matter (WM) were calculated (T/WM).Immunohistochemical stain methods were used to evaluate the level of HIF-1α and measure the MVD in tumors.Correlation analysis between SUV_(max) of T/WM and HIF-1α level,MVD wag performed.The t-test,one-way ANOVA test,Spearman rank correlation and Wilcoxon signed-rank test were calculated using SPSS 11.5 software.Results (1)The SUV_(max) of T/WM,HIF-1α level and MVD in high-grade and low-grade tumors groups were 3.39±1.43,95.7% and 44.13±16.1 vs 1.46±0.55.55.6% and 18.83±7.07,respectively.The difierences of SUV_(max) of T/WM,HIF-1α level and MVD between two groups were statistically significant (t=-5.921,z=-3.938,t=-6.745,all P＜0.05).(2)Among 41 gliomas,the strong positive expression of HIF-1α was observed in 8,mederate in 9,weak in 15 and negative expression was found in 9,SUV_(max) of T/WM and MVD increased with increasing HIF-1α level.The differences of SUV_(max) of T/WM and MVD among 4 different groups were statistically significant (F=7.41,P＜0.05).(3) The MVD of all gliomas was ranged from 9.76 to 94.52,which correlated with SUV_(max) of T/WM(r=0.759,P＜0.05).Conclusions The SUV_(max) of T/WM correlates with HIF-1α level and MVD in gliomas.Therefore,~(18)F-FDG PET provides preoperatively a noninvasive assessment of hypoxia or angiogenesis in human glionma.

OBJECTIVETo observe the efficacy of Chinese herbs for supplementing qi and activating blood circulation (CHSQABC) on patients with acute coronary syndrome (ACS) and type 2 diabetes mellitus (DM) after successful percutaneous coronary intervention (PCI).

METHODSIn this ChiCTR-TRC-00000021, a total of 281 ACS patients complicated with type 2 DM after successful PCI were randomly assigned to the Western medicine treatment group (the control group, treated by routine Western medicine treatment) and the combined treatment group (the treatment group, treated by CHSQABC + routine Western medicine treatment). Patients in the combined treatment group took Xinyue Capsule (2 pills each time, 3 times per day) and Compound Chuanxiong Capsule (2 pills each time, 3 times per day for half a year and 1-year follow-ups). Primary endpoints covered incidence of death, nonfatal myocardial infarction (MI), ischemia-driven revascularization, and secondary endpoints included stroke, heart failure, and rehospitalization for ACS. At the same time scores for blood stasis syndrome (BSS) and the incidence of angina pectoris were evaluated before treatment, at month 1, 3, 6, 9, and 12 after treatment.

RESULTSThe incidence of ischemia-driven revascularization was obviously less in the treatment group than in the control group (P < 0.05). No patient had nonfatal MI in the treatment group, while 5 patients in the control group had it. The incidence of non-fatal MI showed an obvious lowering tendency in the treatment group, but with no statistical difference when compared with that in the control group (P > 0.05). Four patients readmitted to hospital in the treatment group, while 12 patients readmitted. There existed obvious tendency in the treatment group, but with no statistical difference when compared with that in the control group (P > 0.05). The incidence of angina was significantly lower in the treatment group at month 6, 9, and 12 than that at month 1 , but it was lower in the control group at 9 months (P < 0.05). The incidence of angina was 15. 4% in the treatment group, obviously lower than that in the control group (26.2%, P < 0.05). Compared with before treatment, scores for BSS were obviously lowered in the treatment group at 1, 3, 6, 9, and 12 months of treatment and in the control group at 3, 6, 9, and 12 months of treatment (P < 0.05). It was obviously lower in the treatment group than in the control group at 3, 6, 9, and 12 months of treatment (P < 0.01).

CONCLUSIONAdministration of CHSQABC combined routine Western medicine treatment could reduce the event of revascularization and post-PCI recurrent angina, and improve scores for BSS of ACS patients complicated with DM after PCI.
