Objective To determine the value of soluble triggering receptor expressed on myeloid cells 1 (sTREM-1) in patients with stable chronic obstructive pulmonary disease (sCOPD). Methods From 2015 January to 2015 August, 101 patients with stable chronic obstructive pulmonary disease and 81 healthy controls were en-rolled. All subjects underwent pulmonary function test to record FEV1%pred and FEV1%FVC and their serum sTREM-1 levels were determined. Arterial blood gas analyses and COPD assessment tests were also conducted in stable COPD patients. Results Serum sTREM-1 levels were significantly higher in stable COPD patients than healthy controls (113.2 ± 31.5 pg/mL and 83.8 ± 17.9 pg/mL respectively, P=0.000). sTREM-1 levels were posi-tively correlated with CAT score (r=0.507, P=0.000), whereas negatively correlated with FEV1%pred and PaO2 (r = 0.507, P = 0.000; r = 0.439, P = 0.000). Conclusion sTREM-1 is a promising biomarker to evaluate sCOPD in the future.

Objectives To explore the correlation of level of serum 25-hydroxyvitamin D with pulmonary function in adult with asthma. Methods Patients were divided into Asthmatic group(n=62)and Control group (n=28). The Asthmatic group was further divided into Mild Group (n=6), Moderate Group (n=13) and Severe Group (n=43). Serum levels of 25-hy?droxyvitamin D [25(OH)D], denoted as 25(OH) Vit D was detected by ELISA. Pulmonary function indicators,including FVC (forced vital capacity) , FEV1 (forced expiratory volume in 1 second) , FEV1%predicted , and FEV1/FVC%were deter?mined by a pulmonary function testing device. General profiles such as medical history, age and height as well as serum VitD levels were compared between subgroups of the asthmatic groups and between two genders. Serum levels of 25 (OH) VitD were compared between asthmatic group and control group while its correlation with FEV1%predicted were calculated in all three sub asthmatic groups. Results There was no significant difference in medical history, age, height and the 25(OH) VitD levels between male and female participants. Serum 25(OH) Vit D level was significantly lower in the asthmatic patient group [(29.69±20.45) nmol/L] compared to that in control group [(75.16±4.06) nmol/L] (P<0.05). It was significantly lower in severe sub group than those in the mild and moderate sub groups. The differences were both statistically significant ( P<0.05). There were positive correlations between serum 25(OH) Vit D levels and FEV1%predicted ( P<0.05) in all sub asth?matic groups. Conclusion Vitamin D deficiency is highly prevalent in asthmatic patients, and there is a strong correlation between 25(OH) Vit D asthma severity as well as between lung function.

Vitamin D not only regulates calcium-phosphorus balance, but also possesses more extensive bone biological effects.Recent epide-miological researches have shown that vitamin D deficiency is associated with impaired pulmonary function, increased incidence of inflammatory and infectious or neoplastic diseases.This article reviews the influence of vitamin D deficiency on the respiratory diseases.

Objective To investigate the effect of 3R intensive nursing care for patients with Alzheimer Desease in cognitive function and quality of life.Methods Sixty-six of patients with AD in hospital were randomly divided into the experimental group and the control group.Patients in control group just accepted general medical care.Pailents in experimental group accepted general medical care and 3R intensive training,Reminiscence,Reality and Remotivation.All patients were evaluated respectively with IADL,FIM,WAIS-RC and MMSE about life quality improvement.Results Scores of MMSE and WMS of patients in the control group reduced after 6months.which did not change in the experimental group.Scores of ADL and FIM of patients in the control group did not change,but which improved in the experimental group(P<0.05).Conclusions Three R intensive training can improve cognitive function of patients with AD and can be helpful for their activities of daily living,which may be an effective measure for prevention of the aggravation of the patients'symptom and improving of patients'qualities of life.

Recent clinical research shows that a prolonged infusion administration strategy of β-lactam antibiotics compared with intermittent infusion,may improve microbiologic and clinical cure,especially when pathogens demonstrate higher minimum inhibitory concentrations (MIC).This article reviews β-lactam pharmacodynamic background and advantages,clinical benefits and risks,clinical efficacy and potential drawbacks of prolonged infusion β-lactam antibiotics.

To confirm the hypothesis that the high frequency sequences of high throughput sequencing are the terminal sequences of the bacteriophage genome. An adaptor of specific sequence was linked to the end of the bacteriophage T3 genomic DNA, which was then subject to high throughput sequencing; as a control, the same T3 genomic DNA without adaptor was also analyzed by high throughput sequencing. The sequencing results were examined with bioinformatics software. Similar high throughput sequencing technique was applied to analyze the genomic sequence of N4-like bacteriophage IME11. Bioinformatics study showed that the sequences tagged with adaptors were consistent with the high frequency sequences without adaptor labeling. Our analysis also indicated that the end of the T4-like phage genome had specific sequences instead of random sequences, disagreeing with the previous assertion. Evidences were provided that N4-like bacteriophage had a particular terminal sequence: the left end of the genome was unique while the right end was permuted. The high throughput sequencing technique was convenient and practical to be used to simultaneously detect the terminal sequence and the complete sequence of bacteriophage genome.
