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.

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.

Objective To observe the clinical efficacy of Wenjing Shexue Recipe ( WSR) in treating polycystic ovarian syndrome ( PCOS) with liver-kidney deficiency, and to explore the possible therapeutic mechanism. Methods Seventy-four PCOS patients were randomized into observation group ( N=38) and control group ( N=36). The observation group was given oral use of WSR and the control group was treated with Ethinylestradiol and Cyproterone Acetate Tablets orally. Both groups received treatment for 6 months, and were followed up for 3 moths after drug withdrawal. After treatment, the therapeulic effect was evaluated , and the changes of body mass index ( BMI) , hairiness. acne, and sexual hormone levels were monitored before and after treatment. Results ( 1) The total effective rate of the observation gorup was 92.11% and that of the control group was 75.00%, the difference being significant ( P<0.05). ( 2) After treatment for 6 months, body mass index (BMI), the scores of hairiness and acne, and serum levels of testosterone (T) and luteotrophic hormone (LH) were decreased in the observation group (P<0.05 compared with those before treatment). The control group had lower scores of hairiness and acne and serum levels of T and LH than those before treatment ( P<0.05) , but BMI showed no obvious decrease (P>0.05) . The results of follow-up showed that BMI, the scores of hairiness and acne, and serum levels of T and LH were still lower in the observation group than those before treatment (P<0.05), but the above indexes except acne scores were increased in the control group (P>0.05 compared with those before treatment) and were higher than those of the observation group (P<0.05). Conclusion WSR exerts better effect for the treatment of PCOS with liver-kidney deficiency than Ethinylestradiol and Cyproterone Acetate Tablets, and the possible mechanism is probably related with the regulation of endocrine disturbance by decreasing serum T and LH levels.

Objective To understand the significance of upper eyelid swelling in early diagnosis and treat-ment of infectious mononucleosis(IM).Methods We early diagnosed these patients IMwith upper eyelid swelling, fever and lymph node enlargement under five days course of disease,and compared the coincidence rate with last diag-nosis,investigated the rate of upper eyelid swelling in non -early diagnosis cases with the course of disease above one week,and evaluated the effect of ganciclovir in treating IMin two groups.Results The coincidence rate was 97.14%in early and last diagnosis groups,and the rate of upper eyelid swelling was 60.2% in non -early diagnosis group.

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.
