Objective To observe cocultured TAMs cell U937 and NSCLC cell A549 effecting on MCP-1, MIP-1 expression under different conditions in vitro. Methods The cell UM937 of different concentrations (0,1,2,4,8×105/ml) was respectively selected to coculture with the cell A549 0f certain concentration (1.0×105/ml) for 24 hours, in situ hybridization was carried out to detect MCP-1, MIP-1mRNA positive expressions in cell A549 of every concentration group. Under the condition that both concentrations of cell A549 and cell U937 are l.0×105/ml, the same method was used to measure MCP-1, MIP-1mRNA positive expressions in cell A549 in different periods (4h, 8h, 16h, 32h, 48h). Results The positive expression ratios of MCP-1, MIP-1mRNA in cell A549 significantly increased along with addition of the cell U937 concentration and delay of the cocultural time, apparently higher than that of primary cocultured group that the cell U937 was 0×105/ml and that of contrast group at every period (all P<0.05). Conclusion The mutual interaction between TAMs and NSCLC cells has closely positive correlation with MCP-1, MIP-1mRNA positive expressions in cell A549, and depends on cocultural concentration and time.

Executive function is a superordinate cognitive function of the brain. Executive dysfunction post stroke plays a very impor-tant role in recovery of motor function, which is associated with motor learning, postural control, etc. Executive function training may pro-mote the recovery of motor function. The potential neurological mechanism includes the cerebral network involving a variety of areas.

AIM: To investigate the clinical effect of cataract combined lens dislocation greater than 2 quadrants` patients after having phase I intracapsular cataract extraction and anterior vitrectomy,postoperative corrected vision greater than 0.3,and then taking phase II small incision suture-fixation of intraocular lens suspension.METHODS: Totally 34 cases with cataract combined lens dislocation greater than 2 quadrants had been treated in our hospital from July 2014 to December 2016.We investigated their 1wk,1 and 3mo postoperative complications and the uncorrected visual acuity,best corrected visual acuity,intraocular pressure,corneal astigmatism who took phase II small incision suture-fixation of intraocular lens suspension with corrected vision greater than 0.3 after having phase I intracapsular cataract extraction and anterior vitrectomy.RESULTS: Along with the recovery time extension,patients` uncorrected visual acuity and best corrected visual acuity increased obviously than preoperative in each phase.On the 3mo postoperatively,the best corrected visual acuity of 1 eyes was between 0.3 and 0.1,8 eyes was between 0.5 and 0.3,16 eyes was between 0.7 and 0.5,and 9 eyes was better than 0.7.The best corrected visual acuity was achieved or near the best corrected visual acuity before surgery.Intraocular pressure rechecked became in the normal range at 1wk,1 and 3mo postoperative.Surgery did not significantly increase the corneal astigmatism.CONCLUSION: It is a safe and effective way in improving eyesight effectively,with stable intraocular pressure and fewer complications towards cataract combined lens dislocation greater than 2 quadrants` patients having phase I intracapsular cataract extraction and anterior vitrectomy,whose postoperative corrected vision greater than 0.3,and then phase II small incision suture-fixation of intraocular lens suspension.

OBJECTIVE To investigate the drug-resistance status of clinically isolated Staphylococcus aureus(SAU) and provide scientific evidence for clinically reasonable use of antibiotics.METHODS Retrospective review was adopted to analyze the specimen source and the clinical distribution of 311 SAU strains.BioMerieux VITEK 32 was used to identify SAU.Antibiotic susceptibility testing was performed by K-B method.RESULTS Isolating rate of meticillin-resistant S.aureus(MRSA) was 48.9%.SAU were resistant to the diverse antibiotics in different degree except for 100% sensitivity to glycopeptide antibiotics.The drug-resistance to antibiotcs in MRSA were all higher than those in meticillin-sensitive S.aureus(MSSA).CONCLUSIONS Monitoring and controlling of antibiotics resistance are effective measures of prevention from nosocomial infections.

Objective To observe secretive ability of three C-C chemokines, macrophage inflammatory protein-1?(MIP-1?),MIP-1? and regulated-upon activation.normal T-cell expressed and secretory factor(RANTES)by lympocytes and moncytes of cord blood from chinese necnates and peripheral blood from chinese adults.Method Using Ficoll density-gradient centrifugation and gelatin-coated flask,the Iympocytes and monocytes were isolated from cord blood samples of seventeen Chinese neonates and peripheral blood samples of twenty Chinese adults.Purified lymphocytes and monocytes were incubated with PMA and LPS,respectively.Supernants were tested by ELISA for concentrations of MIP-1?,MIP-1? and RANTES.Results Concentrations of MIP-1?, MIP-1? and RANTES in cord blood lymphocyte and monocyte were (3920?730)pg/ml, (4910?590)pg/ml,(1470?410)pg/ml,(3240?980)pg/ml,(1960?1300)pg/ml and (240?120)pg/ml,respectively,and in adults peripheral blood were (6560?840)pg/ml,(5810?1150)pg/ml,(2250?570)pg/ml,(3010?1350) pg/ml,(2280?870)pg/ml,(690?430)pg/ml,respectively.Cord blood lymphocyte and monocyte showed diminished ability to secrete RANTES than adult peripheral blood.Conclusions The diminished RANTES secretion of cord blood lymphocyte and monocyte may be releted to the pathogenesis of Chinese neonatal HIV infection,and indicated some immunotherapies are feasible for preventing neonate from HIV mother-to-child transmission.

Objective To gain purified platelets for further research of the immune function of platelet.Methods Platelets were purified by positive(MS) and negative(LD) magnetic cell sorting(MACS) separation.The percentage of activated platelets was detected by flow cytometry and nucleated cell clearance was evaluated by white cell count.Results The percentage of activated platelets before separation was(2.39?1.10)%,and increased to(2.56?1.08)% and(16.76?4.04)%,respectively,after MS and LD MACS.The clearances of nucleated cells after MACS MS and LD were(98.44?0.24)% and(98.47?0.18)%,respectively.The recovery rate of purified platelet after MS and LD was(76.50?1.49)% and(79.20?2.61)%.Conclusion MACS LD method was more suitable for the platelet purification.

Objective Study on fetomaternal immuno state and RHD type of a pregnant woman of weak D phenotype.MethodsThrough polymerase chain reaction (PCR)、direct genomic DNA sequencing and flow cytometry.ResultsIn both sequence specific promer (SSP) PCR and the sequencing PCR tests, the sample was detected negative in exons 3 6 of the RHD gene, whereas all other exons (exons 1 2,7 10) were tested positive. And the sequence of detected exons (exons 1 2,7 10) are the same with normal RHD in GenBank (accession no. AJ299020 1 and AJ299026 9). Serologically and genetically, the sample can be designated as D category VI type Ⅲ. Through a duce tube PCR method, the RhD zygosity of this individual was typed CD VI e/cde。In flow cytometry, a few fetal erythrocytes were detected in peripheral blood of the mother. However there were no anti D detected in sera and hemolytic disease of the newborn(HDN) observed at all.ConclusionSevere cases of HDN have occurred in D positive babies born to partial D mother with anti D, although HDN don't take place in this case. We may still consider D VI phenotype individuals as D positive donors and D negative receiptions in our transfusion practice and in clinical anti D allo immune prophylaxis and monitoring.
