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: 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 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.

Objective:To explore the correlation among serum uric acid (UA) level and severity of coronary heart disease (CHD) ,adverse cardiovascular events .Methods :Clinical data of 403 patients undergoing coronary angiog-raphy in our hospital were retrospectively analyzed .They were divided into CHD group [n=308 ,including 137 cases with stable angina pectoris (SAP) and 171 cases with acute coronary syndrome (ACS)] and normal control group (n=95 ,non-CHD patients) .UA level was compared among all groups and its correlation with CHD severity was fur-ther analyzed .According to UA level ,CHD patients were divided into low UA group (n=147) and high UA group (n=161) ,after 12-month follow-up ,incidence rate of major adverse cardiovascular events (MACE) uring follow-up was compared between two groups .Results:Serum UA level of ACS group was significantly higher than that of nor-mal control group [ (318.44 ± 69.07)μmol/L vs .(295.38 ± 80.08)μmol/L ,P=0.003];along with number of dis-eased coronary vessels increased and CHD severity aggravated (Gensini score rose ) ,serum UA level showed an in-creasing trend [single-branch (316.58 ± 95.27 ) μmol/L vs . double-branch (335.26 ± 43.26 ) μmol/L vs . multi-branch (346.53 ± 86.74) μmol/L ;low score group (312.42 ± 48.26) μmol/L vs .middle score group (346.58 ± 47.36)μmol/L vs .high score group (363.84 ± 54.68)μmol/L , P<0.05 or <0.01] .Pearson correlation analysis indicated that serum UA level was positively correlated with Gensini score (r=0.583 ,P<0.05);MACE incidence rate in high UA group was significantly higher than that of low UA group (58.38% vs .36.24% , P=0.012) .Con-clusion:Serum uric acid level is positively correlated with severity of coronary heart disease ,which may be an inde-pendent risk factor for coronary heart disease .

Objective To evaluate the value of transvaginal two-dimensional ultrasound(2D-TVS)and transvaginal three-dimensional ultrasound (3D-TVS) in the diagnosis of intrauterine lesions with abnormal uterine bleeding.Methods Intrauterine lesions for 171 patients underwent 2D-TVS followed by 3D-TVS in the same session.Within 10 days of the sonographic session,each patient underwent pathologic histology examination after hysteroscopy examination or surgery therapy,which was considered the reference standard.For each of the two imaging methods,sensitivity,specificity,and accuracy were calculated.Results The results of 2D-TVS and 3D-TVS had good agreement with pathological results in endometrial hyperplasia,endometrial polyps,uterus submucous myoma and endometrial cancer.For 2D-TVS,sensitivity was 84.5％,71.4％,86.8％,66.7％,and specificity was 86.7％,90.7％,97.0％,98.7％,respectively; For 3D-TVS,sensitivity was 91.4％,87.3％,92.1％,83.3％,and specificity was 93.8％,96.3 ％,97.7 ％,98.7 ％,respectively.The diagnose accordance rate of the 3D-TVS for intrauterine lesions was statistically higher than that of the 2D-TVS (89.5％ vs 78.9％,P ＜0.05).Conclusions The sensitivity and diagnose accordance rate of 3D-TVS was higher than that by 2D-TVS,3D-TVS plays an important role in the diagnosis and differential diagnosis of intrauterine lesions.

Objective: To investigate the effects of nursing interventions on mood in patients with coronary heart disease, who performed after percutaneous coronary intervention (PCI). Methods:Retrospective analysis of all patients who Performed PCI in Shunyi District Hospital in 2012.
