Objective To investigate the expression of DNA damage and repair gene Apurinic/apyrimidinic endonuclease (APE1) protein in nasal NK/T cell lymphoma, and elucidate its clinical implication. Methods Expression of APE1 proteins was detected immunohistochemically in 10 normal lymph nodes and human nasal NK/T cells from lymphoma of 64 patients and their integral optical density was determined by means of image analytic system. The proliferation index and apoptosis index were determined by means of immunohistochemical staining and terminal dUTP nickend labeling (TUNEL) technique. Results 1. Nuclear, nucleus/cytoplasmic and cytoplasmic types of APE1 positive staining could be noted in nasal NK/T cell lymphoma. Expression of APE1 gene in nucleus was significantly strengthened compared to that in nucleus/cytoplasm and cytoplasm. In relapse or refractory group, no relapse or refractory group, and normal control group, the positive degree of cytoplasmic staining diminished significantly in the above order (P

Objective To improve the sleep quality of patients by evaluating the effect of relaxation training in combination with listening to music on sleep quality of patients with intracranial aneurysm who underwent endovascular interventional therapy. Methods 55 patients who reached the entrance standard were divided into the observation group (28 cases)and the control group(27 cases).The control group received routine nursing measures. The observation group were given relaxation training in combination with listening to music based on routine nursing measures. The sleep quality was appraised by Pittsburgh Sleep Quality Index (PSQI) and patients subjective feeling was investigated by self-designed questionnaires. Results The relaxation training in combination with listening to music ameliorated the sleep quality in the observation group compared with that of the control group(P＜0.01).Conclusion The relaxation training in combination with listening to music could improved the sleep quality of patients with intracranial aneurysm who underwent endovascular interventional therapy.

Objective To evaluate the effects of propofol on apoptosis in the hippocampal neurons of fetal rats in vitro.Methods The isolated hippocampal neurons were seeded into 96-well plates or 24-well plates at a density of 5 × 104 cells/ml.The cells were randomly divided into 5 groups (n =18 each) using a random number table:control group (group C),in tralipid group (group Ⅰ) and propofol 1,10,100 μmol/L groups (P1-3 groups).In group Ⅰ,10％ intralipid was added to the culture media until the final concentration reached 100 μmol/L.In groups P1-3,propofol was added to the culture media until the final concentration reached 1,10 and 100 μmol/L,respectively,and the cells were then incubated for 3 h.The cell apoptosis was assessed by flow cytometry.The expression of Bcl-2 mRNA and caspase-3 mRNA was detected by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR).The expression of Bcl-2 and actived-caspase-3 protein was determined by Western blot analysis.The apoptosis rate was calculated.Results Compared with group C,the apoptosis rate was significantly increased,the expression of Bcl-2 mRNA and protein was down-regulated,and the expression of caspase-3 mRNA and actived-caspase-3 protein was up-regulated in P1-3 groups (P ＜ 0.05).There was no significant difference in the parameters mentioned above between group Ⅰ and group C (P ＞ 0.05).Conclusion Propofol induces apoptosis in isolated hippocampal neurons by inhibiting Bcl-2 expression and enhancing caspase-3 activity in fetal rats.

The underlying effect of different concentrations of neogenin on proliferation, apoptosis and the related proliferative factors in human trophoblasts was explored in order to understand the function of neogenin during placentation. TEV-1 cell line was cultured and the expression of netrin-1 was detected by using indirect cellular immunofluorescence. Exponentially growing TEV-1 cells were treated by different concentrations of neogenin (0, 1, 5, 10, 50 ng/mL) for 24 h. Cell viability was measured by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. TEV-1 cell apoptosis was assessed by flow cytometry (FCM). The expression of netrin-1 mRNA and protein in TEV-1 cells was examined by using real-time PCR and Western blot, respectively. It was found that immunoreactivity for netrin-1 was observed in cytoplasm of the trophoblasts. Immediately after treatment with different concentrations of neogenin for 24 h, the netrin-1 expression began to increase. Real-time PCR revealed that the expression level of netrin-1 mRNA was 37.59+/-10.25 times higher than control group when TEV-1 cells were exposed to 50 ng/mL neogenin (P<0.01), and the same tendency was seen by using Western blot. MTT results showed that proliferation of TEV-1 cells was independent of neogenin. Meanwhile, apoptosis was significantly increased to (22.15+/-6.15)% at 50 ng/mL neogenin and (6.55+/-0.25)% without neogenin (P<0.01). It is suggested that neogenin regulates proliferation and apoptosis of TEV-1 cells. And it can enhance the ability of TEV-1 cells to express netrin-1 in a dose-dependent manner. Neogenin may play an important biological role in the normal human pregnancy and contribute to the physiological pregnancy process.

Methods Clinical controlled trials of evaluating effects of raltitrexed on the advanced gastric cancer were searched in PubMed,EMBase,Ovid,Springer,Wanfang database,VIP database and China Biology Medicine disc. Besides,references and conference abstracts were searched manually. Literature screening and data extraction were performed according to inclusion and exclusion criteria. Then Meta-analysis was performed using RevMan 4. 2. Results Forty-four studies were found and 5 clinical controlled trails including 338 patients were included in this analysis. The results of Meta-analysis showed that there was a significant beneficial effect of raltitrexed on objective effective rate for the patients with advanced gastric cancer(RR = 1. 55,95% CI:1. 21-1. 99,Z = 3. 44,P = 0. 00)compared with other treatments. The incidences of Ⅲ-Ⅳadverse reactions in raltit-rexed group such as neutropenia(RR = 1. 97,95% CI:0. 85-4. 56,Z = 1. 59,P = 0. 11),thrombocytopenia (RR = 1. 56,95% CI:0. 60-4. 07,Z = 0. 92,P = 0. 36),anemia(RR = 2. 43,95% CI:0. 61-9. 78,Z =1. 25,P = 0. 21),arthralgia(RR = 3. 20,95% CI:0. 73-13. 98,Z = 1. 55,P = 0. 12),elevated transaminase (RR = 1. 37,95% CI:0. 29-6. 48,Z = 0. 39,P = 0. 69)were higher than those in other group,with no statis-tical significance. However,the adverse reactions in raltitrexed group such as diarrhea(RR = 0. 18,95% CI:0. 03-1. 07,Z = 1. 88,P = 0. 06),nausea and vomiting(Z = 1. 79,RR = 0. 45,95% CI:0. 19-1. 08,P =0. 07),neurotoxicity(RR = 0. 07,95% CI:0. 01-0. 52,Z = 2. 59,P = 0. 01),hand-foot syndrome(RR =0. 26,95% CI:0. 04-1. 59,Z = 1. 46,P = 0. 14),alopecia(RR = 0. 57,95% CI:0. 13-2. 55,Z = 0. 73, P = 0. 46)were lower than those in other group. There were no statistical significances except neurotoxicity. Conclusion Compared with other treatments,raltitrexed-based chemotherapy has a beneficial effect on objec-tive effective rate and less adverse reactions for the patients with advanced gastric cancer,which is worthy of clinical use.
