Objective To explore the relationship between the aerocyst continual inflation and clocked deflation and ventilator-associated pneumonia. Methods 60 ICU hospitalized adult patients treated with tracheotomy or trachea canalization for above 24 hours were randomly divided into the tzadi-tional group and the experimental group with 30 patients in each group. After trachea canalization success-fully according to the nursing standard, the experimental group was treated with aerocyst continual inflation, the traditional group gased the ventilator and recorded the time, deflating the gas every 4 hours and inflating again after 5 minutes. The inflation time, nurse management and MOV(minimal occlusive volume)of the two groups were the same. The chest X-rays examination and deep sputum bacilli culture were implemented 12 hours after admission, before pulling out the ventilator and transferring out of ICU to evaluate the inci-dence of ventilator-associated pneumonia according to the infection diagnosis standard. Results The rate of ventilator-associated pneumonia in the experimental group was obviously lower than that of the tradition-al group. Conclusions The rate of ventilator-associated pneumonia reduces obviously in the ICU trachea canalization patients with aerocyst continual inflation.

Oligonucleotide microarray technology is a powerful data-mining platform and has been widely applied in biosciences. To improve the performance of assays on the oligonucleotide microarray, the factors that influence the hybridization effects such as surface chemistry, probe size, spacer length, hybridization conditions etc were intensely studied and optimized. However, it is a key problem with DNA microarrays how to generate higher fluorescent signals to improve the detection sensitivity. Two types of multiply labeled primers, termed multiply labeled linear primer and multiply labeled branched primer, were used to enhance the fluorescent signal obtained from two-dimensional DNA microarrays.The signal was intensified by increasing the number of fluorophores labeled on the target DNA segment. It was indicated that the detection limit (minimum template amoumt for detection) of the multiply labeled primers is about 1% of that of the singly labeled primer. Multiple labeling is an effective signal amplification method to increase the detection sensitivity of the probes in a miniaturized array format.

OBJECTIVE:To discuss the association between ABCB1 gene polymorphisms and adriamycin and cyclophospha-mide(AC)combined with chemotherapy-induced severe neutropenia in patients with breast cancer. METHODS:218 breast cancer patients receiving AC combined with chemotherapy were selected from our hospital during 2012-2015;PCR-RFLP was used to de-tect polymorphisms of ABCB1 2677G>T/A and 3435C>T. The associated between different age,BMI,clinical stages genotypes, etc and AC combined with chemotherapy-induced severe neutropenia were investigated,and risk factors of neutropenia were ana-lyzed by multivariate logistic regression. RESULTS:Among 218 breast cancer patients,170 patients suffered from severe neutrope-nia,accounting for 78.0%. Among ABCB1 2677G>T/A polymorphisms,distribution frequency of GT or GA genotype,TT,TA or AA genotype,GG genotype in severe neutropenia were 80.6%,86.2% and 60.0%,with statistical significance (P<0.05). Among ABCB1 3435C>T polymorphisms,distribution frequency of TT,CT and CC genotype in severe neutropenia were 86.4%, 78.4% and 72.7%,there was no statistical significance(P>0.05). AST and ABCB1 2677G>T/A polymorphisms were correlated with severe neutropenia (P<0.05),and ABCB1 2677G>T/A polymorphism was a strong predictor of neutropenia [OR=3.875, 95%CI(1.555,9.922),P=0.008]. CONCLUSIONS:ABCB1 2677>T/A polymorphisms may be aggravate AC combined with che-motherapy-induced neutropenia in patients with breast cancer.
