Objective To establish the fingerprint of amino acids composition of Jinlong capsule. Methods Using 6-acetamido-4-hydroxy-2-methyl quinoline (AQC) as the derivating agent, 17 kinds of amino acids were analyzed by UPLC at the same time and the fingerprint of amino acids composition of Jinlong capsule was established. Result Totally 22 co-possessing peaks were selected as the fingerprint peaks, 17 kinds of amino acids were identified. The fingerprint similarity value of 10 batches was above 0.9. Conclusion The fingerprint is characteristic and can be used for the quality control of Jinlong capsule.

To study the antiarrhythmic effect of the newly developed alpha/beta-blocker TJ0711, a variety of animal models of arrhythmia were induced by CaCl2, ouabain and ischemia/reperfusion. Glass microelectrode technique was used to observe action potentials of right ventricular papillary muscle of guinea pig. The onset time of arrhythmia induced by CaCl2 was significantly prolonged by TJ0711 at 0.75, 1.5 and 3 mg x kg(-1) doses. TJ0711 (1.5 and 3 mg x kg(-1)) can significantly shorten the ventricular tachycardia (VT) and ventricular fibrillation (VF) duration, the incidence of VF and mortality were significantly reduced. On ischemia-reperfusion-induced arrhythmic model, TJ0711 (0.25, 0.5, 1 and 2 mg x kg(-1)) can significantly reduce the ventricular premature contraction (PVC), VT, VF incidence, mortality, arrhythmia score with a dose-dependent manner. At the same time, rats serum lactate dehydrogenase (LDH) and creatine kinase (CK) activities decreased significantly by TJ0711 (1 and 2 mg x kg(-1)). Ouabain could cause arrhythmia in guinea pigs, when TJ0711 (0.375, 0.75, 1.5 and 3 mg x kg(-1)) was given, the doses of ouabain inducing a variety of arrhythmia PVC, VT, VF, cardiac arrest (CA) were significantly increased with a dose-dependent manner. In the TJ0711 0.1-30 micromol x L(-1) concentration range, guinea pig right ventricular papillary muscle action potential RP (rest potential), APA (action potential amplitude) and V(max) (maximum velocity of depolarization) were not significantly affected. APD20, APD50 and APD90 had a shortening trend but no statistical difference with the increase of TJ0711 concentration. TJ0711 has antiarrhythmic effect on the sympathetic nerve excitement and myocardial cell high calcium animal arrhythmia model. Myocardial action potential zero phase conduction velocity and resting membrane potential were not inhibited by TJ0711. APD20, APD50 and APD90 were shortened by TJ0711 at high concentration. Its antiarrhythmic action mechanism may be besides the action of blocking beta1 receptor, may also have a strong selective blocking action on alpha1 receptor and reducing intracellular calcium concentration.

Objective:To investigate the demands for cardiac rehabilitation information in patients with coronary atherosclerotic heart disease (CHD) and influential factors.Methods:Information demands for cardiac rehabilitation in CHD patients were surveyed by questionnaire and the influential factors were analyzed by one-way ANOVA and multi-factor analysis of variance.Results:The score of demands for cardiac rehabilitation information in CHD patients was 3.86±0.53.Among them,the most urgent top 5 items were:drug knowledge,diagnosis and treatment,basic knowledge of the heart,emergency and safety and nutrition knowledge.The top 3-demand modes were:communication with medical workers,movies or videos to take home,and lectures.The score of demands for cardiac rehabilitation information was different in different age groups.The highest score was in the patients with age less than 60.There were different demands in different characteristic groups.Conclusion:The most urgent need and mode are drug knowledge and communication with medical workers,respectively.With the age increase,the demands for patients' cardiac rehabilitation information decrease.An individualized health education strategy should be developed according to the characteristics of CHD patients.

Objective To establish a national antibacterial resistance surveillance network and explore the epidemiology of bacterial resistance in China. Methods The minimal inhibitory concentration (MIC) was determined by National Committee for Clinical Laboratory Standards (NCCLS) standard agar double dilution method. The susceptibility and resistance rates of drugs were calculated according to the criteria in guidelines of NCCLS (2004). Results According to the previous protocol, a total of 4 075 pathogenic strains isolated from 17 hospitals located at 15 different cities from October 1, 2004 to September 30, 2005 in China were collected and the MICs were detected. Gram-negative bacilli were 3 150 strains ( 77.3%). Enterobacteriaceae Were highly susceptible to Carbapenems. In addition, Moxalactam, Piperacillin/Tazobactam, Cefoperazone/Sulbactam and Cefepime were also exhibited good antibacterial activities against Enterobacteriaceae,the resistance rates of them were less than 10 %. The resistance rates of nonfermentative Gramnegative bacilli, such as Pseudomonas aeruginosa and Acinetobacter baumanii, to Imipenem were 10. 6 % and 10.4 % , respectively. Cefoperazone/Sulbactam, Piperacillin/Tazobactam and Fluoroquinolones also showed good activity against nonfermentative Gram-negative bacilli.Conclusions The drug resistance rates of Escherichia coli and Acinetobacter baumanii increase obviously. Fluoroquinolones and Aminoglycosides are not very effective against Enterobacteriaceae,which should be paid more attention.

As an anchoring protein,receptor for activated C kinase 1 ( RACK1 ) can combine together with many kinds of intracellular signaling molecules and participate in many signal conduction in cells.Researchers have paid close attention to the role of RACK1 in signal transduction molecule network of tumor cells.Abundant studies reveal that RACK1 can regulate signal transduction by regulating tumorigenesis and immune escape in tumor cells,and then play important roles.
