Objective:To explore the infective routes and the pathogen type distribution of ventilator associated pneumonia (VAP).Methods: 183 ventilator associated pneumonia patients (75 cases were early-onset VAP and 108 cases were late-onset VAP, and the different point was whether machine had been used 72 h) who once were treated in intensive care unit(ICU)during the term of January 2013 and December 2015 were researched in this paper. To collect samples from phlegm in lower respiratory tract, secrete of oropharynx, air sac of tracheal catheter, stomach juices, ventilator channel and condensate water, and identify pathogens and detect drug allergy. To compare the difference of pathogens distribution and infective routes between early-onset VAP and late-onset VAP by comparing identified result of the same case.Results: In 294 strains bacteria collected from different collective points, 71.09% was gram-negative bacteria, 21.09% was gram positive bacteria, 7.82% was fungus, and 129 strains were multiple-resistant bacteria. Gram-negative bacteria and gram positive bacteria in late-onset VAP patients were less than early-onset VAP patients, but the fungus was more than them, and the difference was statistically significant (x2=14.193, P=0.001); besides, the stains of multiple-resistant bacteria of late-onset patients were more than others, and the difference also was statistically significant (x2=26.375, P=0.000). Most of infection of VAP were original from stomach juices and tracheal catheter air sac, both of them were 59.77%. Most of early-onset VAP were infected by stomach juices and secrete of oropharynx, and most of late-onset VAP were infected by tracheal catheter air sac, ventilator channel and condensate water(x2=31.450,P= 0.000).Conclusion: The clinical prevention and cure for VAP should adopt comprehensive measures which depend on the aeration time of machine because there are some differences on pathogens distribution and infective routes between late-onset VAP and early-onset VAP. This research provide a evidence for efficiently prevent the occurrence and development of VAP in hospital.

Objective:To answer the question whether executive function(EF) deficits are specific to attention deficit hyperactivity disorder(ADHD) or whether such deficits are also associated with disruptive behavior disorders(DBD),including oppositional defiant disorder(ODD) and conductive disorder(CD).Methods:A total of 19 pure ADHD boys,19 ADHD + DBD boys and 19 normal controls(criteria of DSM-Ⅳ) were collected as our samples.The groups were matched by age(less than 6 months).The research instruments included Stroop color-word task,Rey complex figure test,digit span test, trail making test,tower of Hanoi and verbal fluency test.Results:The differences of IQs weren't significant among three groups.(1) Both pure ADHD group and ADHD+DBD group performed worse(P0.05).(2) Pure ADHD group also showed deficits in the aspects of errors of Stroop 2,time and errors of Stroop 3, word interference time;immediate memory structure score of Rey complex figure test;time and errors of number-letter part and shifting time of trail making test;total time and steps of completing tower of Hanoi.The differences were significant(P

Objective:To study the executive function(EF)characteristics in boys with attention deficit hyperactivity disorder(ADHD)comorbid learning disabilities(LD).Methods:A total of 22 pure ADHD boys,22 ADHD + LD boys and 22 normal controls(by criteria of DSM-Ⅳ)were collected as our samples.The groups were matched by ages(less than 6 months)and ADHD subtypes.The research instruments included the Stroop color-word task,Rey complex figure test,digit span test,trail making test,tower of Hanoi and verbal fluency test.Results:The differences of VIQ weren't significant among the three groups;pure ADHD and ADHD+LD groups had lower PIQ than the control group;ADHD+LD boys had lower IQ than the controls.The performance in the EF tests:(1)Both pure ADHD and ADHD+LD groups performed worse in the aspects of time of number-letter part and shifting time,the repeat response of verbal fluency,and the differences were significant.But the differences between ADHD and ADHD+LD weren't significant.(2)ADHD+LD group also showed deficits in the aspects of time and errors of Stroops 2 and 4,time of Stroop 4,word interference time,the immediate memory and delayed recalling detail score of Rey complex figure test,time of number trail making,error steps(rule violation)of Tow of Hanoi,and the differences were significant.(3)Both ADHD+LD and pure ADHD groups made more errors in the naming color of the color-word card(Stroop part 4),and ADHD+LD boys performed worse than pure ADHD boys.Conclusion:The findings support the hypothesis that ADHD is related to EF deficit,whether or not comorbid LD.ADHD+LD showed significant difference in the aspects of inhibition,working memory,set shifting and fluency as compared with normal group,ADHD+LD boys perform more poorly than the pure ADHD boys.It's plausible that both ADHD and LD are associated with deficits of executive function.

Objective To investigate the relationship between gallbladder stone with blood lipid levels ,body weight index (BMI) and distribution of TCM constitution .Methods A total of 698 cases of gallstone in our two hospital from September 2013 to February 2015 were selected as the experiment group ,and contemporaneous 253 cases of abdominal hernia ,gallbladder polyp and other diseases were included into the control group .The TCM constitution identification investigation was performed and the TCM constitution distribution was observed .The blood lipid levels and BMI were compared between the two groups .The risk of blood lipid level and BMI to gallstone occurrence was evaluated .Results The normal constitution in the experimental group accounted for 12 .2% ,the top three places of the biased constitution were phlegm‐damp nature ,Qi deficiency nature and damp heat nature ,which accounted for 29 .4% ,17 .0% and 11 .0% respectively .The TC and VLDL‐C level and BMI in the male and female patients of the experiment group were higher than those in the control group ,moreover the TG level in the female patients of the experiment group was significantly higher than that in the control group ,the difference was statistically significant (P< 0 .05) .The increase of TC (OR=2 .87) ,VLDL‐C(OR=6 .32) and BMI (male:OR=2 .43 ,female:OR=2 .01) were the risk factors of gallstone occurrence . Conclusion Increase of TC ,VLDL‐C and BMI are the risk factors of gallstone occurrence ,the TCM constitution of gallstone pa‐tients is dominated by the phlegm‐damp nature .

Objective To explore the effects of tamoxifen on the proliferation of SHG-44 glioma cells and the currents of sodium channel. Methods The cell activity was detected by MTT. The alteration of cellular proliferation and apoptosis were dectected by flow cytometer. Whole-cell patch clamp technique was used to record the Na currents.Results After treatment with tamoxifen,the cells began aging and shedding and cell counting decreased.The cells in G2/M cell cycle were more than that in control and the apoptosis ration increased. Tamoxifen significantly decreased the amplitude of Na currents of SHG-44 cell line.This blocking effect was dose-dependent and voltage-dependent.When the holding potential was 0 mV, 8 ?mol/L tamoxifen could block this currents by 69%.The half inhibition concentration(IC50) was 5.54 ?mol/L. Conclusion Tamoxifen can inhibit SHG-44 glioma cells proliferation.The inhibion of sodium channel may be one of its mechanisms.
