ABSTRACT
Based on the physiological and pathological characteristics of meridian sinew theory, the staging treatment of non-specific low back pain (NLBP) is explored to provide the reference of clinical practice. The twelve meridian sinews of the human body communicate with the bones and joints of the whole body, which governs the movement, body protection and defense, and meridian regulation. Physiologically, the meridian sinew maintains the functions of the lumbar region. In pathology, the meridian sinew may encounter stasis and pain, contraction and spasm or "transverse collateral" formation. According to the pathological staging of meridian sinew disorders, the progress of NLBP is divided into 3 phases and the corresponding treatments are provided. Mild stimulation and rapid analgesia is suggested to promote tissue repair at the early phase; muscle spasm is relieved to adjust muscular status at the middle phase; and the "cord-like" muscle foci is removed at the later phase of the disease.

Objective To investigate the effect of comprehensive intervention measures on submission of microbiological specimens before therapeutic use of antimicrobial agents.Methods August 2014 to August 2015 was as preintervention group,comprehensive intervention measures were started to carry out from September 2015,Septem ber 2015 to September 2016 was as post-intervention group.Microbiology specimen submission rates before therapeutic antimicrobial use,positive rate of blood culture,and rate of antimicrobial use in all departments and key departments were compared between pre-intervention group and post-intervention group.Results The submission rates of microbiological specimens before general,restricted,and special therapeutic antimicrobial use increased from 42.21％,45.19％,and 74.71％ of pre-intervention respectively to 53.54％,55.68％,and 89.70％ of postintervrntion respectively,showing significant difference (all P＜0.01);after intervention,except gastrointestinal surgery and trauma department of orthopedics,the other departments all met the requirements of the microbiological specimen submission rates set by the hospital;but submission rates of microbiological specimens from department of gastrointestinal surgery and trauma department of orthopedics increased from 5.46％ and 11.67％ before intervention to 11.66％ and 29.45％ respectively after intervention,difference was statistically significant (both P＜0.001).The missing report rate of healthcare-associated infection(HAI) dropped from 13.56％ before intervention to 10.98％ (P＜ 0.05),and the use rate of antimicrobial agents decreased from 57.36％ to 54.47％ (P＜0.001).Conclusion Comprehensive intervention measures can effectively improve the submission rates of microbiological specimens before therapeutic use of antimicrobial agents,reduce missing report rates of HAI and utilization rate of antimicrobial agents,and achieve certain clinical effectiveness.
ABSTRACT
Objective To understand the occurrence of healthcare-associated infection (HAI),distribution of pathogens,and drug resistance in a general hospital in 2014-2016,provide basis for prevention and control of HAI.Methods Clinical data of hospitalized patients from January 2014 to December 2016 were collected by prospective and retrospective investigation,distribution and drug resistance of pathogens causing HAI were statistically analyzed.Results From 2014 to 2016,4 750 patients had 5 352 cases of HAI,incidence and case incidence of HAI were 2.19％ and 2.46％ respectively.Incidences of HAI in three years were 2.47％,2.07％,and 2.05％ respectively,showing a decreased tendency,difference was statistically significant (x2 =36.217,P＜0.01).Incidences of HAI were high in intensive care unit,department of neurosurgery,as well as department of burn and plastic surgery,the common HAI sites were respiratory tract,urinary tract,and surgical sites.The main pathogens causing HAI were gram-negative bacteria (76.10％).Resistance rates of Escherichia coli to cephalosporins and fluoroquinolones were relatively higher (＞60％);resistance rates of Klebsiella pneumoniae to carbapenems were relatively higher;resistance rates of Pseudomonas aeruginosa to carbapenems showed a increased tendency year by year (x2 =15.175,P =0.001);antimicrobial resistance rates of Acinetobacter baumannii were all＞50 ％.Methicillin-resistant Staphy lococcus aureus (SA) accounted for about 60％ of SA,methicillin-resistant coagulase negative Staphylococcus(CNS) accounted for more than 80％ of CNS,vancomycin-and linezolid-resistant Staphylococcus spp.were not found.Conclusion The common pathogens causing HAI in this hospital are higher.Scientific monitoring on HAI and regular analysis of clinical data are of great significance for guiding rational use of antimicrobial agents,controlling multidrug-resistant organisms,and reducing the occurrence of HAI.
ABSTRACT
<p><b>BACKGROUND</b>This meta-analysis evaluated the effect of noninvasive, positive pressure ventilation on severe, stable chronic obstructive pulmonary disease (COPD).</p><p><b>METHODS</b>PUBMED, CNKI, Wanfang, EMBASE and the Cochrane trials databases were searched. Randomized controlled trials of patients with severe, stable COPD and receiving noninvasive positive pressure ventilation, compared with sham ventilation or no ventilation, were reviewed. The mortality, physiological and health related parameters were pooled to yield odds ratio (OR), weighted mean differences or standardized mean differences (SMD), with 95% confidence interval (CI).</p><p><b>RESULTS</b>Eight parallel and three crossover randomized controlled trials met the inclusion criteria. Pooled analysis for parallel, randomized controlled trials showed noninvasive positive pressure ventilation: (1) Did not affect the 12- or 24-month mortality (OR 0.82, 95%CI: 0.48 to 1.41); (2) Improved the arterial carbon dioxide tension (SMD -0.88, 95%CI: -1.43 to -0.34); (3) Did not improve forced expiratory volume in one second (SMD 0.20, 95%CI: -0.06 to 0.46), maximal inspiratory pressure (SMD 0.01, 95%CI: -0.28 to 0.29) or 6-minute walk distance (SMD 0.17, 95%CI: -0.16 to 0.50); (4) Subgroup analysis showed noninvasive positive pressure ventilation improved the arterial carbon dioxide tension in hypercapnic patients. Pooled analysis for crossover randomized controlled trials did not show improvement in arterial blood gas or forced expiratory volume in one second with noninvasive positive pressure ventilation.</p><p><b>CONCLUSIONS</b>Noninvasive positive pressure ventilation improves the arterial carbon dioxide tension but does not improve the mortality, pulmonary function, or exercise tolerance and should be cautiously used in severe stable chronic obstructive pulmonary disease.</p>

<p><b>BACKGROUND</b>Human antigen R (HuR) is a ubiquitously expressed member of the ELAV family, and has relatively high cytoplasmic abundance in lung tissue regenerating after injury. In this study, we investigated whether mitogen-activated protein kinase (MAPK)-activated protein kinase 2 (MK2) and HuR participate in the tumor necrosis factor (TNF)-induced expression of interleukin-6 (IL-6).</p><p><b>METHODS</b>Human pulmonary microvascular endothelial cells were treated with TNF following short interfering RNA-mediated knockdown of MK2 or HuR. Cell supernatants were collected to detect the mRNA and protein expression of IL-6 at different time points. The expression and half-life of IL-6 mRNA were then determined in cells that had been treated with actinomycin D. Finally, after knockdown of MK2, the cytoplasmic expression of HuR protein was analyzed using Western blotting.</p><p><b>RESULTS</b>MK2 or HuR knockdown decreased both the mRNA and protein expression of IL-6 in TNF-stimulated cells. In MK2 knockdown cells, the half-life of IL-6 mRNA was reduced to 36 minutes, compared with 67 minutes in the control group. In HuR knockdown cells, the half-life of IL-6 mRNA decreased from 62 minutes to 24 minutes. Further analysis revealed that knockdown of MK2 resulted in reduced HuR protein expression in the cytoplasm.</p><p><b>CONCLUSIONS</b>MK2 regulates the TNF-induced expression of IL-6 by influencing the cytoplasmic levels of HuR.</p>
