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.

BACKGROUND:An increasing number of studies have shown that mesenchymal stem cels have the potential to treat acute kidney injury. Umbilical cord-derived mesenchymal stem cels have general characteristics of stem cels and many advantages, such as easy to isolate and culture, in vitrofast amplification, low immunogenicity and no ethical problems, which have garnered increasing attentions. OBJECTIVE:To study the repairing effects of human umbilical cord-derived mesenchymal stem cels on acute kidney injury in rats. METHODS: Thirty rats were randomized into three groups: a normal control group, a model group and a cel transplantation group. Rats in the model and cel transplantation were subjected to clamping the renal pedicles for 45 minutes, and then injected 1 mL of DAPI-labeled umbilical cord-derived mesenchymal stem cels or 1 mL of saline via the tail vein. In the normal control group, the kidney was only exposed with no treatment. At 7 days after treatment, the rats were kiled to take left kidney tissues for pathological observation under light microscope and right kidney for observation of DAPI-positive cel counting. Automatic biochemical analyzer was used to detect serum creatinine and urea ammonia levels. RESULTS AND CONCLUSION: Compared with the model group, the levels of serum creatinine and urea ammonia were significantly lower in the cel transplantation group (P < 0.05), suggesting that human umbilical cord-derived mesenchymal stem cels can improve the kidney function to a certain extent. Pathological findings showed that the pathological damage was improved more remarkably in the cel transplantation group than the model group, and the tubular necrosis index decreased significantly in the cel transplantation group. At 7 days after cel transplantation, blue fluorescent cels were scattered on renal tissue frozen sections. These results indicate that human umbilical cord-derived mesenchymal stem cels can migrate to the injured tubular epithelial tissues, and promote the repair of the injured kidney.

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.

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.

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.
