Objective To study the role of protein kinase B(PKB) in gastric cancer BGC-823 cells treated by TPA. Methods Flow cytomety(FAC) and fluorescence microscope were used to detect the effect of TPA on gastric cancer BGC-823 cells,after cells were treated by BrdU and stained by DAPI,respectively.The effect of TPA on the expression level of PKB protein and its phosphorylation of Ser 473 and Thr 308 were investigated by Western blotting.When nuclear and cytoplasmic protein fractions were prepared through lysis of cell and centrifugation,the effect of TPA on the expression level of PKB protein and its phosphorylation of Ser 473 in cytoplasm and nuclei were detected by Western blotting.Meanwhile,the effect of TPA on the distribution of PKB was observed under laser-scanning confocal microscope with immunofluorescence technique. Results TPA induced the apoptosis of gastric cancer BGC-823 cells.It also induced the inhibition of PKB protein expression in a TPA concentration-dependent and time-dependent manner in gastric cancer BGC-823 cells,regardless of dephosphorylation of PP2A.TPA inhibited the phosphorylation of PKB at Ser 473,but it did not affect its phosphorylation at Thr308.TPA only attenuated the expression level of PKB and its phosphorylation of Ser 473 in nuclei,whereas it did not change the distribution of PKB in BGC-823 cells.Conclusion These data suggest that the inhibition of PKB plays an important role in mediating the effect of TPA in gastric cell line.Apoptosis induced by TPA is partly due to the inhibition of PKB and its phosphorylation of Ser 473 in nuclei.

Chinese herbal property theory (CHPT) is the fundamental characteristic of Chinese materia medica different from modern medicines. It reflects the herbal properties associated with efficacy and formed the early framework of four properties and five flavors in Shennong's Classic of Materia Medica. After the supplement and improvement of CHPT in the past thousands of years, it has developed a theory system including four properties, five flavors, meridian entry, direction of medicinal actions (ascending, descending, floating and sinking) and toxicity. However, because of the influence of philosophy about yin-yang theory and five-phase theory and the difference of cognitive approach and historical background at different times, CHPT became complex. One of the complexity features was the multiple methods for determining herbal property, which might include the inference from herbal efficacy, the thought of Chinese Taoist School and witchcraft, the classification thinking according to manifestations, etc. Another complexity feature was the multiselection associations between herbal property and efficacy, which indicated that the same property could be inferred from different kinds of efficacy. This paper analyzed these complexity features and provided the importance of cognitive approaches and efficacy attributes corresponding to certain herbal property in the study of CHPT.

Chinese herbal property is the highly summarized concept of herbal nature and pharmaceutical effect, which reflect the characteristics of herbal actions on human body. These herbal actions, also interpreted as presenting the information about pharmaceutical effect contained in herbal property on the biological carrier, are defined as herbal property expressions. However, the biological expression of herbal property is believed to possess complex features for the involved complexity of Chinese medicine and organism. Firstly, there are multiple factors which could influence the expression results of herbal property such as the growth environment, harvest season and preparing methods of medicinal herbs, and physique and syndrome of body. Secondly, there are multiple biological approaches and biochemical indicators for the expression of the same property. This paper elaborated these complexities for further understanding of herbal property. The individuality of herbs and expression factors should be well analyzed in the related studies.

Depression is a worldwide neuropsychiatric disorder. Currently most preclinical and clinical studies of depression focus on monoaminergic system. However, there is growing evidence which suggests that glutamatergic system plays a critical role in the pathophysiology of depression. This review focuses on the de-velopment of new antidepressants that target glutamatergic sys-tem, summarizes the current mechanisms of antidepressants, and also highlights new insights to the pathophysiology of depression.

Objective: To investigate the effects of nursing interventions on mood in patients with coronary heart disease, who performed after percutaneous coronary intervention (PCI).
