0.05).Using Hamilton depression (HAMD) and Hamilton anxiety (HAMA) rating scales, or using HAMD, HAMA and social disability screening schedule (SDSS) to determine the prognosis groups, the change of platelet 5-HT content had significant difference in the group with good prognosis (P

To investigate the genetic diversity among wild Dipsacus asperoides in China, 66 germplasmic resources of D. asperoides were analyzed by Start Codon Targeted Polymorphism (SCoT) molecular markers. Genetic distance was calculated by TREECONW software and the systematic diagram of genetic relationship was clustered by UPGMA method. The results showed that the totals of 181 bands were detected using 20 primers , among which 109 were polymorphic bands. The average percentage of polymorphic bands was 60.13%. Genetic distance changed from 0.030 6 to 0.181 4. The clustering results showed that there was no significant correlation between the classification of the wild D. asperoides and their geographical origin. The relatively high genetic diversity of D. asperoides provides the basis for breeding new varieties.

A series of novel sorafenib analogues were designed and synthesized. The cytotoxic activities of these compounds were tested in four tumor cell lines. Some of the compounds showed potent antiproliferative activity against the tested cell lines with IC50 = 4-20 micromol x L(-1). Some compounds demonstrated competitive antiproliferative activities to sorafenib against tested cancer cell lines. Among them, compound 7c demonstrated significant inhibitory activities on ACHN, HCT116 and MDA-MB-231 cell lines with IC50 values of 9.01, 4.97, 6.61 micromol x L(-1), respectively.

A strain of P. Aeruginosa,which was seperated from clinical environment,shows a special characteristic. It keeps normal short rod shape when cultured at 37℃, however,it forms filament without pyocyanin producing when cultured at 25℃ overnight. The filaments will divide and form short rods, simultaneously, produce pyocyanin when culture time is prolonged to over 72h or culture temperature is raised to 37℃. The preliminary study indicates that this phenomenin has nothing to do with nutritive conditions and could the inbluenced by inoculating density and irradiating with ultraviolet rays The absence of pyocyanin was not the cause of filamentous formation by the test results.

Curcumin has been reported to possess antitumor activity with low toxicity. However, the clinical application of curcumin has been significantly limited by its instability and poor metabolic property. In order to overcome these limitations and discover novel small molecules with potential antitumor activity, 29 curcumin mimics were synthesized, which were confirmed by 1H NMR and HR-MS, and their cytotoxic property was evaluated against five human cancer cell lines in vitro. Compounds 16, 18 and 19 exhibited good cytotoxic property, their IC50 value were even below 5 micromol x L(-1) to some cancer cell lines, 5-9 times better than curcumin.

Mitotic catastrophe is a new form of cell death,which is the phenomenon of cell death caused by the disorder of mitosis.It is a true endogenous mechanism of tumor suppression.However,although mitotic catastrophe is important in the prevention and treatment of tumors,the molecular mechanism of its occurrence has not been clearly elucidated.In this paper,we will discuss the latest research progress on the mechanism of mitotic catastrophe in tumor cells,and provide a reference for further study on the mechanism of mitosis catastrophe.
