Objective To investigate the clinical effects of high-density micropulse photocoagulation (HD-SDM) combined with intravitreal injection of ranibizumab for diabetic macular edema (DME).Methods Thirty-one patients (31 eyes) with DME were randomly divided into two groups.Group A (15 eyes) received HD-SDM combined with intravitreal injection of ranibizumab.Group B (16 eyes) only received intravitreal injection of ranibizumab.The best corrected visual acuity (BCVA) and central macular thickness (CMT) of the two groups before and after treatment were analyzed,and the annual injection times of the two groups were compared.Results The average annual injection times was 3.67 ± 1.11 in group A,and 9.12 ±2.63 in group B.The difference was significant between the two groups (t =2.05,P ＜ 0.05).There were significant differences in CMT before and after treatment in both groups (all P ＜ 0.05).There was no significant difference in CMT between the two groups(t =1.19,P ＞ 0.05).There were significant differences in BCVA before and after treatment in both groups (all P ＜ 0.05),but there was no significant difference before and after treatment between the two groups(all P ＞ 0.05).Conclusion Both HD-SDM combined with intravitreal injection of ranibizumab and single intravitreal injection of ranlbizumab are effective for DME,but the combining treatment can remarkably decrease the annual injection times and had a good compliance of patients,is a good choice for DME patients.

Lipase from Burkholderia cepacia complex is one of the most versatile biocatalyst and is used widely in many biotechnological application fields including detergent additives, the resolution of racemic compounds, etc. Based on the known whole genomic information of B. cepacia, both ampicillin and kanamycin were added to the TB-T media, the traditional selective media, to screen B. cepacia complex strains from rhizosphere soil samples. The single colonies on the plates with the modified TB-T media were then qualitatively determined the ability to produced the extracellular lipase in the rhodamine B-olive oil agar plates. Thirty-five strains of lipolytic pseudo-B. cepacia complex were isolated and the positive rate of lipolytic bacteria was 65%. Among them, 15 pseudo-B. cepacia complex strains with the tolerance to benzene, n-hexane and n-heptane at the concentration of 10% (V/V) were selected and identified by the recA gene sequence. All of the 15 lipolytic bacteria belonged to the B. cepacia complex.

Background and purpose:As a tumor suppressor gene, ribosomal S6 kinase 4 (RSK4) plays important roles in inhibiting cell proliferation, migration and inducing cell apoptosis. However, the proteins interacting with RSK4 are still unknown. This study aimed to screen proteins interacting with RSK4 in breast cancer cell line MDA-MB-231 by lfag-tag affnity puriifcation and LC-MS/MS (liquid chromatography/mass spectrometry).Methods:The pcDNA3.1/EGFP-RSK4-Flag eukaryotic expression vector was constructed by inserting full lengthRSK4 gene into vector pcDNA3.1/EGFP-Flag. And then the recombinant plasmids were transferred into MDA-MB-231 cells. Real-timelfuorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot were used to detect the expression of RSK4 in MDA-MB-231 cells. Affnity puriifcation and LC-MS/MS were applied to screen proteins interacting with RSK4, and the related action mechanism of RSK4 with its interacted proteins was detected based on bioinformatics gene ontology (GO) and ingenuity pathway analysis (IPA).Results:Twenty-four proteins, such as serine/threonine-pro-tein kinase 38 (STK38)/serine/threonine-protein kinase 38-like (STK38L), MOB kinase activator 2 (MOB2) and protein arginineN-methyltransferase 5 (PRMT5), were successfully identiifed by Flag-tag affnity puriifcation followed by LC-MS/MS analysis, which probably interacted with RSK4. Bioinformatics analysis of the identiifed proteins suggested the proteins interacting with RSK4 were involved in diverse biological pathways, such as apoptosis and cell migration. Conclusion:According to bioinformatics results of proteins interacting with RSK4 identiifed by affnity puriifcation and LC-MS/MS, biological networks of RSK4 are involved in apoptosis and migration in breast cancer cells.
