Objectire To identify specific biomarkers that could improve early diagnsis of lung adenuearcinoma using matrix-assisted laser desorptian/ionization (MALDI) technology. Methods Serum samples were isolated from 17 patients with stage I lung adenuearcinoma and 17 age- and sex-matched healthy controls, and the serum proteomic profiles were obtained by matrix-assistcd laser desorption ionization time of flight (MALDI-TOF) mass spectrometry. Results Compared with healthy control group, two highly expressed potential biomarkers were identified with the relative molecular weights of 6 631.64 Da and 4 964. 21 Da. The two best novel protein peaks were automatically chosen for the system training and the development of the constructed model. The constructed model was then used to test an independent set of masked serum samples from 15 lung adenocarcinoma patients and 22 healthy individuals. The analysis yielded a sensitivity of 93.3 %, and a specificity of 95.5 %. Conclusion These results suggest that MALDI-TOF-MS ProteinChip technology is a quick, convenient, and high-output analyzing method that is capable of selecting several relatively potential biomarkers from the serum of lung adenocarcinoma patients and may have a clinical value in the future, and will provide clues to identifying new serologic btomarkers of lung adenocarcinoma.

Objective To screen the factors that can affect α-toxin expression of CA-MRSA except for quorum-sensing system and to investigate the regulative mechanism of the interesting genes. Methods S. aureus CA-MRSA transposon mutagenesis library was constructed by using mariner based transposon mutagenesis system. The clones with significantly changed level of hemolysis were selected, the location of erm insertion in a gene was confirmed by arbitrary primed (inverse) PCR and nucleotide sequence. Genetic complementation, mice bacteremia and skin abscess models and real time RT-PCR were used to study the function of the interesting gene. Results Twenty-five mutants with down-expression of α-toxin were selected by screening about 104 isolates of transposon mutagenesis library. The hemolytic diameter of CA-MRSA wild type was about 212 mm, no clear hemolysis was found in AraC-, The hemolytic diameter of AraC-pT181 araC was about 197 mm. Real time RT-PCR results showed that compared to the expression of the virulence factors in CA-MRSA wild type( PSMα 257. 30 ±37. 33 ;agr 115. 60 ±0. 81 and α-toxin 3.23 ±0. 21), in AraC-, α-toxin, PSMα and agr were significantly down regulated(α-toxin 1.09 ±0.01 :t = 10. 18, P <0.01 ;PSMα 34.85 ±2. 15:t=5.95,P<0.05;agr35. 19 ±1. 72:t =42. 33, P<0. 01). The result of mice bacteremia model showed that the virulence of wild type and AraC- ( (x) ± s ) were significantly different (x2 = 21. 34, P < 0.01). The expression of PSMα, agr and α-toxin in AraC-pT181araC ( PSMa 180.10 ± 15.29;agr 101. 50 ±8. 96;α-toxin 2.59 ±0.26) had no significant difference compared to the expression of the virulent factors in CA-MRSA wild type (PSMα: t =1.914, P>0.05;agr:t= 1.563, P>0.05;α-toxm: t = 1. 923, P > 0. 05 ). There were no significant difference of the expression of ClpP in AraC-(0. 21 ±0.01) and in AraC-pT181araC(0.17 ±0.03)compared to the expression of ClpP in CA-MRSA wild type (0. 20 ± 0.01) (t=0.555, P>0.05 and t=0. 851, P>0.05). The result of mice skin abscess model showed that the dermonecrosis area caused by CA-MRSA was (136. 5 ±21.45) mm2, the dermonecrosis area caused by AraC- was (55. 69 ± 13. 81) mm2, the different was significant (t = 3.169, P < 0. 05). Conclusion In CA-MRSA, AraC-type transcriptional regulator controlled the pathogenesis of CA-MRSA by regulating the expression of the most important virulence factors such as hla, PSMα and agr.

Objective To assess the effect of remote-interactive cognitive behavioral therapy in pa-tients with chronic insomnia.Methods A total of 62 patients with chronic insomnia were randomly divided into combined treatment group,cognitive behavioral therapy for insomnia ( CBTI) group and drug treatment group.The study lasted for 6-8 weeks.The curative effects were assessed using sleep diary and scales.Results The sleep onset latency (SOL) ((39.9±23.7)min) and wake time after sleep onset(WASO) ((79.1± 39.4) min) in the drug treatment group were higher than that in the combined treatment group ( ( 25.5 ± 11.2)min and (54.4±38.5)min,respectively) and CBTI group ((27.8±11.6)min and (51.8±29.0)min,re-spectively) at the end of treatment,the difference was statistical significance( P=0.018 and P=0.046 respec-tively).The sleep efficiency(SE) in drug treatment ((76.5±11.9)%) was lower than that in the other two groups((83.8±8.7)%and (82.8±7.0)%respectively),(P=0.042).And no similar difference were seen in TST after treatment(P>0.05).The Brief Version of Dysfunctional Beliefs and Attitudes about Sleep(DBAS-16) score in the drug treatment group (97.6±16.4) was higher than the other two groups((67.5±20.1) and ( 75.0±26.9) respectively) after treatment(P=0.000) .No significant difference was seen in scores of the oth-er scales among the three groups(P>0.05) .After treatment,a greater proportion of patients in the combined treatment group had withdrawn from hypnotics use completely (29%(6/20) vs 5%(1/18);odds ratio( OR ) was 7.286);and the combined treatment group produced significant reduction in frequency of hypnotics use ((3.35±3.05) nights/week) when compared with drug treatment group((5.56±2.33) nights/week, P=0.016) .Conclusions Remote-interactive cognitive behavioral therapy was effective and acceptable for treating pa-tients with chronic insomnia,combining drug treatment in the early period could quickly relieve the symptoms of in-somnia,and can avoid the adverse effect from the hypnotics.And the treatment method can reduce the dropout rate.
