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.

Objective To investigate the epidemiological characteristics of adverse reaction induced by Chinese herbal injection. Methods Multiple cases report in domestic medical periodicals were searched and analysed by bibliometric and statistic meth-ods. Results Fifty-six reports on muti-ADR cases related to 16 different kinds of Chinese herbal injection were collected. There were 67299 patients and 1348 ADR cases related to Chinese herbal injection. The average ADR incidence was 2.00 % ;the highest incidence of 43.28 % was shown in cinobufotalin injection and the lowest incidence of 0. 25 % in zedoary turmeric oil injection). Skin lesion, and circulatory and digestive lesion dominated in ADRs. Conclusion we should use Chinese herbal in-jection more rationally, and enhance prevention awareness to reduce the incidence of ADR induced by Chinese herbal injection.

BACKGROUND: As a specially differentiated central nerve, optic nerve is once injured, retinal neurons are hard to restore and regenerate. As a result, visual function is lost permanently. Currently, an effective clinical treatment is not available. Due to the multi-directional differentiated potential of stem cells, their role in optic nerve protection and restoration following injury is becoming a hot research spot.OBJECTIVE: To review the classification and transplantation of stem cells in optic nerve protection study, as well as roles of stem cells transplantation in optic nerve protection and repair following injury.METHODS: The database of ISI Web of Knowledge platform was searched on computer from February 1994 to April 2009, with the key words "stem cells, optic nerve" in English. In the same way, the database of CNKI from February 1994 to April 2009 was also screened, with the key words "stem cells, optic nerve" in Chinese.RESULTS AND CONCLUSION: A total of 98 literatures related to stem cells in optic nerve protection and restoration after injury are collected, in which 23 papers are Chinese and 75 papers are English. The studies published earlier, repetitively and similarly are removed, and 38 papers which comply with the standards are involved into this review. Stem cells own the potential of self-renew physiologically, as well as potential of repairing the injuries. At present, most of the researches on stem cells in optic nerve protection and restoration after injury are represented in morphosis. How to implant stem cells safely and effectively and how to recover stable visual function still need our efforts. Stem cells derived from skin, peripheral blood, fat and other tissues are convenient to draw materials and are commendable subjects, we should study them deeply to make preferable use.

Objective To study the implication of phosphoinositide-specific phospholipase C?2(PLC-?2) in gastric cancer MGC80-3 cells treated by TPA.Methods The effect of 12-O-tetradecanoylphorbol-1,3-acetate(TPA) on gastric cancer MGC80-3 cells was detected and analyzed by DAPI staining under fluorescence microscope.The effect of TPA on the expression level of PLC-?2 protein was detected by Western blotting,when nuclear and cytoplasmic protein fractions were prepared through lysis of cell and centrifugation.Localization and translocation of PLC-?2 were observed under laser scanning confocal microscope with immune-fluorescence technique.After MGC80-3 cells were pretreated by U73122(PLC-?2 inhibitor),the effect of TPA on PLC-?2 was detected by Western blotting and laser scanning confocal microscope with immunefluorescence technique,and the effect of U73122 on MGC80-3 cells followed by TPA was observed and analyzed by DAPI staining under fluorescence microscope. Results TPA induced the apoptosis of gastric cancer MGC80-3 cells.Meanwhile,TPA increased the expression level of PLC-?2 protein and induced its translocation from cytoplasm to nucleus.U73122 inhibited the effect of TPA on the expression level of PLC-?2 protein,but it did not affect on the cell apoptosis induced by TPA.However,the translocation of PLC-?2 protein induced by TPA was not inhibited by its inhibitor(U73122).Conclusion Although TPA could increase the expression level of PLC-?2 protein,it is not directly related to the cell apoptosis induced by TPA.However,its translocation might be related with the apoptosis of gastric cancer.

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.
