Objective:To assess the role of EGFR mutations on pemetrexed response in patients with advanced lung adenocarcino-ma. Method: Forty pulmonary adenocarcinoma patients with evaluable lesions were retrospectively screened .They had been treated with pemetrexed-included chemotherapy and had EGFR gene test results. The evaluation endpoints were overall response rate,disease control rate and progression free survival. Result:No significant statistical difference was seen in overall response rate(ORR) (44.4%VS 31.8%, respectively) and disease control rate(DCR) (88.9%VS 81.8%, respectively ) between EGFR wild group and EGFR muta-tion group, but patients in EGFR wild group had longer progression free survival(PFS) ( 8.9 months VS 5.3 months;P=0.046). Conclu-sion:EGFR mutation status can influence the efficacy of pemetrexed.

Objective To investigate the changes of serum cytokines and explore their role in infants with cytomegalovirus (CMV) infection. Methods We recruited 41 positive CMV-IgM plus normal ALT infants (other disease group), 30 positive CMV-IgM plus abnormal ALT infants (hepatitis group) and 30 healthy infants (control group) in the study. The levels of tumor necrosis factor-?(TNF-?), interferon-?(IFN-?) and interleukin-4 (IL-4) in serum were measured with ELISA. The association between TNF-? and ALT was analyzed. Results The levels of TNF-?, IFN-?, IL-4 were higher, and IFN-?/IL-4 was significantly lower in the two CMV infection groups than the control group. Compared with other disease group, the changes of TNF-?, IL-4, and IFN-?/IL-4 showed significance in hepatitis group. The level of TNF-? showed a positive association with ALT in hepatitis group(r=0.76,P

Objective To investigate the molecule phenotype, epidemiology, and resistance genes of the New Delhi metallo- β-lactamase-1 ( NDM-1 ) producing Klebsiella pneumoniae ( K. pneumoniae ) . Methods Retrospective study was made on one hundred and ten non-repetitive carbepenem-resistant K. pneumoniae clinical isolated strains, which were collected from January 2011 to December 2012 in our hospital. The minimal inhibitory concentrations ( MICs ) of antibiotics were tested by the GN13 cards of BioMerieux Company. Modified Hodge test were used for the detection of carbapenemases. The blaNDM-1 encoding gene and linkage of ISAba125-NDM were detected by PCR method. The purified PCR products were cloned and sequenced. The homology of the K. pneumoniae were analyzed by the multilocus sequence typing ( MLST ) . Plasmid conjugation experiment and curing method were used to study the transfer of bacterial resistance. The Fisher′s exact probability test was used to compare the data. Results 13% NDM-1-producing K. pneumoniae were detected and confirmed as blaNDM-1 by sequencing (14/110). The resistance rates of the 14 NDM-1-producing K. pneumoniae strains to imipenem, meropenem, ertapenem, ciprofloxacin, levofloxacin, amikacin, and aztreonam were 14/14, 14/14, 13/14, 10/14, 9/14, 5/14, and 11/14. Meanwhile, the positive rate of ISAba125-NDM linkage of those 14 NDM-1-producing K. pneumoniae strains was 14/14. The E. coli J53 transconjugants, whose MICs of imipenem, meropenem, and ertapenem were increased by 4 to 64 times, were blaNDM-1 gene and ISAba125-NDM linkage positive. In addition, it was showed that the blaNDM-1 gene and ISAba125-NDM linkage were located on a plasmid with a size of approximately 65 000 bp. Conclusions The NDM-1 producing K. pneumoniae strains in this study were resistant to many commonly used antibiotics, however, the resistance rate to aminoglycoside and aztreonam were relatively low. The carbapenemase-resistant genotype spread by blaNDM-1 carried plasmid. Attention should be paid to its easily transmissible feature among the strains in clinic. The insertion sequence ISAba125 may be involved in the blaNDM-1 gene mediated carbapenemase-resistant genotype.

and adenovirns. The high rate of mixed viral infection brings clinical concern. ELISA combined with PCR improve the diagnostic sensitivity for norovirus, enteric adenovirns and astrovirus.

Objective To quantitatively assess the cardiopulmonary exercise function of spinal cord injury (SCI) patients and observe the effect of aerobic exercise on cardiopulmonary function, motor function and activities of daily living. Methods From December, 2014 to June, 2016, 34 incomplete SCI patients (ASIA C and D) and 23 healthy controls received cardiopulmonary exercise test (CPET). SCI pa-tients were randomly divided into conventional rehabilitation group (n=17) and aerobic exercise group (n=17). The aerobic exercise group received aerobic exercise for four weeks. They were assessed with CPET, motor and sensory function, walking index for spinal cord injury II (WISCI II) and spinal cord independence measure (SCIM) before and four weeks after training. Results Oxygen uptake (VO2)peak, anaerobic threshold (AT), metabolic equivalent of energy (METpeak), VO2/heart rate (HR)peak, respiratory exchange rate (RER)peak, minute ventilation (VE)peak, work rate (WR)peak and systolic blood pressure (SBP)peak were lower in the patients than in the controls (t>2.714, P<0.05). VO2peak、AT、METpeak、VO2/HRpeak、WRpeak increased in the aerobic exercise group after training (t>2.431, P<0.05). METpeak and WRpeak improved in the conventional rehabilitation group after training (t>3.282, P<0.01). The scores of motor in ASIA and SCIM improved in both groups after training (t>2.985, P<0.05). Conclusion The cardiopulmonary function decreased in incomplete SCI patients, which could be improved by moderate intensity aerobic exercise.
