Objective To observe the long-term effect of suramin on the inhibition of proliferation of human retinal pigment epithelial (RPE) cells in vitro. Methods RPE cells grown in 9 pieces of 96-well plate (12 wells each plate) were divided into experimental and control group, with 6 wells in each group. The concentration of 0.1 ml RPE cells in each well is 5?104 cells/ml. After the change of the medium, RPE cells were treated with suramin (250 ?g/ml) in experimental group while treated with nothing in the control group. The medium of the 2 groups were changed to the normal medium after 4 days. At the 1~st , 2~nd , and 4~th day after the addition of suramin and at the 1~st , 2~nd , 3~rd , 5~th , 6~th , 7~th , 9~th , 11~th and 13~th day after removing suramin, 1 plate was randomly selected to stop culturing, and the proliferation of RPE cells were detected by methyl thiazolyl tetrazolium (MTT) assay. Results Under reversed microscope, RPE cells in control group were fused completely at the 7~th day after inoculation. The extracellular space of RPE cells in experimental groups was larger than that in the control group, and remained unfused at the 13~th day after inoculation. The inhibitory rate of proliferation of RPE cells at the first day after treated with suramin was 14.85% and increased to the highest 25.79% at the 4~th day. The first day after the suramin-containing media was removed, the inhibitory rate decreased to 12.35%, and then raised gradually to over 20% at the 3~rd to 5~th day. Finally, the rate drop to 14.71%. Conclusion Suramin has the long-term effect on the inhibition of RPE cells induced by serum, especially the inhibitive effect after the remove of suramin, which indicates the specific double-peak inhibition during the whole process.

Objective To identify etiological factors for non-ulcer dyspepsia (NUD) in elderly patients presenting to the emergency department.Methods A total of 97 elderly patients with NUD presenting to the emergency department from January 2011 to December 2013 were enrolled in the NUD group and 116 elderly people undergoing annual physical examinations served as the control group.Clinical data,including Helicobacter pylori (HP) infection,unhealthy living habits,anxiety,depression and regular intake,were collected and compared between the two groups.Results Compared with the control group,the NUP group showed a higher HP infection rate [70.1％ (68/97)vs.54.3％ (63/116),x2 =5.565,P＜0.05],a higher incidence of unhealthy living habits (unhealthy dietary habits,smoking,drinking,and lack of regular exercise) (P＜0.05),a higher incidence of suspect anxiety/anxiety and a higher incidence of regular intake [30.9％ (30/97) vs 10.3％ (12/116),x2=14.138,P＜0.05].SerumpepsinogenⅠ(PGⅠ) [(178.7±13.6) μg/L vs.(125.2±10.5)μg/L,t=1.971,P＜0.01] and serum pepsinogen Ⅱ(PG Ⅱ) [(28.8±5.3) μg/L vs.(14.7±3.8)μg/L,t=1.960,P＜0.01] levels were also higher in the elderly NUD patients than in the control group.Conclusions HP infection,unhealthy living habits,anxiety and/or depression,and regular intake are closely associated with NUD in the elderly.Serum PGⅠ and PGⅡ could be used as markers in screening for malignant lesions in elderly patients with dyspepsia.

AIM: To prepare gfp-bcl-X L-contained recombinant adenovirus(rAd-gfp-bcl-X L).METHODS: Bcl-X L gene was amplified from pEGFP-C 3-bcl-X L, subcloned into shuttle plasmid and formed transfer plasmid of pAdTrack-CMV-bcl-X L. Then pAdTrack-CMV-bcl-X L was linealinzed with PmeI and co-transformed into BJ5183 bacteria with adenovirus genomic plasmid of pAdEasy-1. The identified recombinant adenovirus plasmid was digested with PacI and transfected into 293 cells to package recombinant adenovirus particles. The target gene was detected by PCR.RESULTS: There were about 35% positive recombinant bacterial clones after the co-transformation of pAdTrack-CMV-bcl-X L and pAdEasy-1 into BJ5183. Recombinant adenovirus particle were produced and further amplified after the transfection of pAdEasy-1-gfp-bcl-X L into 293 cells. PCR test indicated that the recombinant Ad contained bcl-X L gene. The titer of the purified rAd-gfp-bcl-X L was 6 5?10 12 PFU/L. CONCLUSIONS: The homologous recombination in bacteria is a convenient and high efficient method to prepare rAd-gfp-bcl-X L. This affords a good gene transfer vector for the gene therapy in human's diseases.

Objective To investigate the clinical value of acoustic radiation force impulse (ARFI) imaging in the evaluation of liver functional reserve in patients with hepatic focal lesions. Methods Eighty-six patients with hepatic focal lesions in General Hospital of the People′s Liberation Army from September 2011 to August 2012 were studied. According to Child-Pugh score, 54 of them were classified as grade A, 18 patients were classiifed as grade B, and 14 patients were classiifed as grade C. Seventy patients underwent surgery and 16 patients underwent non-surgical treatment. Shear wave velocity (SWV) values were measured using ARFI technique, and indocyanine green (ICG) clearance tests were also performed to achieve ICG clearance rate constant (ICGK) and ICG retention rate at 15 minutes (ICG15). Correlation between SWV and ICGK, SWV and ICG15 were studied using Pearson correlation, and correlation between SWV and Child-Pugh score were analyzed using Spearman rank correlation. Difference between SWV values of patients underwent surgery and those of patients underwent non-surgical treatment was compared using t-test for independent samples. Analyses of receiver operating characteristic (ROC) curve were performed to investigate the value of ARFI in the evaluation of surgical feasibility for patients with hepatic focal lesion, with the clinical decisions serving as the golden standard. Results There was correlations between SWV and ICGR15, SWV and ICGK, and SWV and Child-Pugh scores (r=0.764,P <0.001;r=-0.686,P=0.000;r=0.864,P=0.000). The SWV of patients who underwent surgery was (2.46±0.45) m/s, and the SWV of patients who underwent non-surgical treatment was (1.54±0.36) m/s, with a signiifcant difference (t=-0.80, P=0.000). The ROC curve analysis demonstrated a highest Youden′s index of 0.775 when the cut-off was 2.06m/s. The corresponding sensitivity was 87.5% and the specificity was 90.0% for ARFI in the diagnosis liver functional reserve deficiency. Conclusion ARFI can effectively evaluate the liver functional reserve in patients with hepatic focal lesions and thus could be beneifcial in the decision of clinical treatment.

AIM: To investigate the mechanism of the AP-1 signal transduction pathway inhibited by JIP in nasopharyngeal carcinoma cells. METHODS: AP-1 activity was triggered by Dox-induced LMP1 expression in Tet-on-LMP1-HNE 2 cells (L7). The retention of phospho-JNK in the cytoplasm caused by JIP was examined with immunofluroscence assay. RESULTS: 24 h after transfection of L7 cells with the JIP expression plasmid, the translocation of activated JNK was inhibited, which resulted in the retention of phospho-JNK in the cytoplasm and down-regulation of the AP-1 activity. CONCLUSION: JIP down-regulates the activity of AP-1 through the inhibition of the translocation of JNK.

Objective: To observe the therapeutic efficacy of sinew-bone balancing manipulation plus exercise therapy in treating postures of primary school students with upper crossed syndrome (UCS).Methods: Sixty pupils with UCS were divided into an exercise group and a combination group using the random number table method, with 30 cases in each group. The combination group received treatments of sinew-bone balancing manipulation plus exercise therapy, while the exercise group received exercise therapy alone. The two groups received interventions once every other day, for a total of 1 month. The sagittal static posture assessment total score, forward head angle (FHA) and forward shoulder angle (FSA) were compared before and after treatment; the sagittal static assessment total score, FHA and FSA were compared between the exercise group and the combination group. Results: Before treatment, there were no significant differences comparing the sagittal static posture assessment total score, FHA and FSA between the two groups (all P>0.05); after treatment, the sagittal static posture assessment total score, FHA and FSA decreased in the two groups, with intra-group statistical significance (all P<0.01), and were lower in the combination group than in the exercise group, with inter-group statistical significance (all P<0.01). Conclusion: Sinew-bone balancing manipulation plus exercise therapy can notably improve the FHA and FSA and reduce the sagittal static posture total score in pupils with UCS, so as to correct the bad postures and adjust UCS physique. It can produce more significant efficacy compared with exercise therapy alone.
