Objective To observe the impact of improving the compliance of ventilator bundle on morbidity of ventilator-associated pneumonia (VAP) in intensive care unit (ICU) patients undergoing mechanical ventilation (MV) guided by context of Joint Commission International (JCI) settings, and to study the oral care efficacy of suction tube sponge brush. Methods A prospective study was conducted. The patients who needed MV admitted to Department of Critical Care Medicine of the First Affiliated Hospital of Xiamen University from January 2013 to December 2016 were enrolled. In the context of JCI settings, necessary measurements were taken to enhance the compliance of ventilator bundle each year. In 2013, the preventive measures were set up and the education was strengthened. In 2014,the compliance of hand hygiene and bedside elevation was strengthened. In 2015, a control study was conducted to evaluate the effect between the traditional cotton dipped in chlorhexidine and the suction tube sponge brush rinsed with chlorhexidine on oral health impact parameters. The suction tube sponge brush rinsed with chlorhexidine oral care was introduced to improve compliance. In 2016, electronic bundle checklist for daily self-audits was conducted. The annually morbidity of VAP through the software of hospital and ICU was collected and calculated. The annual incidence of VAP was indicated by the VAP cases per 1000 MV days. Based on the VAP incidence rate in 2013 as 1, the VAP incidence-rate ratio (IRR) of each year was calculated. Results During the study period, a total of 2733 patients admitted to the ICU, including 1403 patients undergoing MV. Ninety-four of the 1403 patients with community-acquired pneumonia (CAP), aspiration pneumonia, back elevation ban, incomplete information, and withdrew from the study were excluded. 1399 patients undergoing MV were enrolled in the final analysis, with total MV days of 11012 days, and 94 patients occurred VAP. The annual incidence of VAP was progressively declined from 2013 to 2016, and the VAP cases per 1000 MV days were 17.0, 10.0, 5.9, 3.5 cases, respectively. Based on the VAP incidence rate in 2013, the IRR of VAP from 2014 to 2016 was also progressively declined, which was 0.59 [95% confidence interval (95%CI) = 0.35-0.98], 0.35 (95%CI = 0.18-0.64), and 0.21 (95%CI = 0.09-0.41), with statistical significance (all P < 0.05). In 2013, ICU patients had the lowest rates of bedside elevation and hand hygiene compliance, which were 28.57% and 54.29%, respectively. Compared with 2013, by the implementation of two quality control circle (QCC) projects for bedside elevation and hand hygiene, the rates of bedside elevation and hand hygiene compliance were improved significantly in 2014, which were 82.35%, 91.18%, respectively (both P < 0.05). In 2015, the compliance of chlorhexidine oral care which was the worst performed in 2014 had been improved by the method of QCC, and the rate of the compliance was significantly higher than that in 2013 (87.10% vs. 62.86%, P < 0.05). Compared with 2013, bundle compliance was significantly increased in 2016, except for the sterile operation of the suction tube [daily wake and weaning: 95.00% vs. 71.43%, bedside elevation for over 30°: 92.50% vs. 28.57%, hand hygiene: 97.50% vs. 54.29%, chlorhexidine mouth care once per 6-8 hours:95.00% vs. 62.86%, turned back and posture drainage: 97.50% vs. 80.00%], the differences were statistically significant (all P < 0.05). The incidences of bad breath, dirt residue and plaque were significantly lower in the group of oral care by using suction tube sponge brush with chlorhexidine (30 cases) compared with the group of traditional cotton pad with chlorhexidine (30 cases; bad breath: 10.0% vs. 40.0% %, dirt residue: 16.7% vs. 70.0%, plaque: 3.3% vs. 30.0%, all P < 0.05). There was no significant difference in the incidence of oral ulcers between the oral brush group and the traditional group (10.0% vs. 30.0%, P > 0.05). Conclusion Ventilator bundle can effectively reduce the morbidity of VAP in the context of JCI settings, and the oral care by using suction tube sponge brush and chlorhexidine can effectively improve oral hygiene.

Objective To clone and express recombinant outer membrane protein P6, determine its optimal expression conditions and to investigate the immunoprotective effects of the P6 protein on mice. Methods The P6 gene of nontypeable Haemophilus influertzae(NTHi) was amplified by PCR from the NTHi genome and cloned into expression vector pET-32a (+) to generate the pET-32a-P6 recombinants. They were confirmed by nuclease digestion and sequence analysis. The verified recombinant was transformed into E. coli BL21 (DE3). Its optimal expression conditions were determined such as engineering strains, the concentration of IPTG, inducing temperature, inducing time, different medium etc. The recombinant protein was purified by Q Sepharose~(TM) XL ion exchange and gel filtration chromatography. The protein was analyzed by SDS-PAGE, Western blot and sequencing. BALB/c mice were immunized with recombinant protein be-fore challenged by NTHi through intraperitoneal injection. Then the mortality rate of different group was com-pared. Results The recombinant P6 of NTHi was successfully constructed and expressed in E. coli at a rel-atively high level. The purity was up to 95% after purification. The relative molecular mass of the protein is 14 145. 848. The recombinant protein was confirmed to show specific reaction on the antiserum through Western blot. The animal experiments showed the mortality rates of immunization groups were significantly lower than that of the control group (P < 0.05). Conclusion The successful expression of the recombinant P6 will be very helpful for the further study on development of vaccine, its purified, immunological activity and antibody preparation.

To set up a new rapid method for the rapid determination of influenza virus H5N1 and H7N9 basing on the Multi-Analyte Suspension Array (MASA) technology. Sequence analysis and design of degenerate primers and specific probes were set in the comparison and analysis of H5, N1, H7 and N9 genes. In combination with MASA technology, these primers and probes were used for the determination of samples of H5N1 and H7N9 and other subtypes ( H1N1, PH1N1, H5N2, H3N2 and H9N2). We developed a rapid determination method. This method had high specificity and sensitivity that could detect H5N1 and H7N9 at one time, and could detect samples that containing 10 copies of H5N1 and H7N9. This determination method could be used for rapid determination of influenza virus H5N1 and H7N9 at one time.

Objective To observe the effect of leptin on proliferation and apoptosis of breast cancer MCF-7 cell line,and to explore the effect of leptin on occurrence and development of breast cancer.Method The MCF-7 cell line was treated with different concentration of leptin in vitro.Cell proliferation was evaluated by MTT assay. Distribution of cell cycle was determined by flow cytomery, meanwhile the rates of apoptosis were estimated on the basis of Annexin V-FITC/PI apoptosis detection. Results When treated with different concentration of leptin for 24 h, 48 h and 72 h, they could significantly induce the proliferation of MCF-7 cells by MTT method.There was not interaction between concentration of leptin and time course (F=0.919,P=0.523).The main effect of concentration of leptin and time course was statistically significant (F=12.699,P=0.000;F=647.881, P=0.000). Compared 200 ng/ml and 400 ng/ml with the control group, we found the difference was statistically significant by multiple comparison (P=0.007,P=0.000,respectively).The difference was also statistically significant among time course by multiple comparison (P=0.000,respectively).By the flow cytometry analysis,it was found that the 100 ng/ml and 400 ng/ml leptin groups could change the distribution of cell cycle of MCF-7 cell line after 48 h. Compared with control group, the cell number decreased by 14.42 ％ in G0/G1 phase (F=10.464, P=0.044),but increased by 7.57 ％ and 22.19 ％ respectively in S phase (F=47.361,P=0.005).The difference was not statistically significant in G2/M phase (F=1.77, P=0.311).However, the effect of apoptosis inhibition was not obvious. Conclusions Leptin could stimulate the proliferation of MCF-7 cell line and change the distribution of cell cycle.But leptin could not inhibit apoptosis of MCF-7 cell line.It suggested that leptin may serve as a risk factor of breast cancer development.
