Circadian rhythms describe biological phenomena that oscillate with an 24 hour cycle. These rhythms include blood pressure, body temperature, hormone level, the number of immune cells in blood, and the sleep-wake cycle. The aim is to introduce common genes between species that are responsible for determining the circadian behavior, especially some transcription factor s that serve to regulate many circadian rhythm genes. And the common molecular mechanism of biological clocks between fly and human will be in troduced.

OBJECTIVE To establish the distribution and the drug resistance of the pathogens of lower respiratory tract infections in a comprehensive intensive care unit(ICU).METHODS The bacterial culturing and the tests on the antibiotic from the deep phlegm in an ICU of the hospital from 2004 to 2005 were retrospectively analyzed.RESULTS Totally 408 phlegm samples were tested and 216 of them had bacteria,the positive rate was 52.94%.From them were isolated 240 strains of bacteria(among them 12 samples with 2 kinds of bacteria).The strains of Gram-negative bacteria were 172 and the positive rate was 71.7%,there were 35 strains of Gram-positive cocci with the positive rate of 14.6%.And there were 33 strains of fungi,the positive rate was 13.7%.Acinetobacter baumannii occupied the first place.The lowest drug resistance rate of the Gram-negatives was to SCF(0.0%),IMP(17.8%),and LEV((20.0%)).All Gram-positive cocci were sensitive to vancomycin,no vancomycin resistant.Staphylococcus were found.Candida albicans was sensitive to all tested drugs.CONCLUSIONS The isolation rate of A.baumannii is significant higher than reported before and its drug resistance is heavier.It indicated the importance of monitoring bacterial distribution and drug resistance dynamics.

Objective To investigate the change of threshold of electrical sense through experiments in the presence of electrical noise according to stochastic resonance phenomenon that has been observed in somatosensory system.Method Psychophysical experiments were carried out using both single stimulus method based on random-gradient method and one-interval-forced-choice method.The glabrous skin of human fingers was choosed as the experimental objects,which was stimulated by square wave electrical signal mixed with electrical noise.Result The corresponding threshold of electrical sense can be reduced by the effect of external electrical noises.Conclusion Although electrical sense is not natural sense,stochastic resonance can occur in it, and effect of noise on enhancing this sense can be implemented by controlling external noises.

MAPKKK (MEKK1 or ASK1)/MAPKK (SEK1 or MKK7)/JNK signal cascade is an important pathway which mediates apoptosis. MAPK phosphotase can deactivate JNK by dephosphorylation of JNK.The interaction between JNK and c-Jun can also be negatively regulated by NO through S-nitrosylation. SGK1 or Akt can result in deactivation of SEK1 through its phosphorylation at the Ser78 site.The c-FLIPL can block this cascade through binding with MKK7.GST Mu1-1 interferes and suppresses MEKK1-mediated apoptosis. GST Pi 1-1 and TRX have a dose-dependent inhibitory effect on ASK1 through forming protein complex. The deactivation of JNK can enhance drug resistance of tumor cells and counteract the injury from a wide variety of stimulus. Here,how these proteins induce deactivation of the pathway and mediate anti-apoptosis has been discussed.

The platelet membrance glycoprotein plays a key role in the adhesion,aggregation and release of platelet.It is the specific molecular marker for platelet activation.Many studies have confirmed that platelet membrane glycoprotein CD62P may be more sensitive and specific to reflect the occurrence of coronary artery development,CD62P level is positively correlated with the severity.A variety of traditional Chinese medicine can lower the CD62P level,inhibit platelet activation and the treatment play an important role in the treatment.
