Objective To understand the status of infection with multidrug-resistant organisms (MDROs) in intensive care units(ICUs),and evaluate the intervention efficacy of targeted monitoring.Methods Prospective study was adopted,patients who were admitted to ICUs in 2014-2015 were selected (January-December 2014 was as preintervention stage,January-December 2015 was as intervention stage),trend of MDRO infection before and after intervention were compared and analyzed.Results Before and after intervention,297 and 217 strains of MDROs were isolated respectively,except carbapenem-resistant Pseudomonasaeruginosa (CRPA),the isolated strains of carbapenem-resistant Acinetobacterbaunannii (CRAB),carbapenem-resistant Enterobacteriaceae (CRE),methicillin-resistant Staphylococcus aureus(MRSA),and vancomycin-resistant Enterococcus (VRE) declined after intervention.MDRO infection rate declined from 7.17 ％ before intervention to 3.88％ after intervention,infection rate of CRAB and CRE after intervention were both lower than before intervention (both P＜0.05);MDRO infection rates in general ICU and internal medicine ICU increased from 8.75％ and 7.84‰ before intervention to 4.39‰ and 2.28％ after intervention,respectively (both P＜0.05).After taking comprehensive intervention measures,compliance to prevention and control measures,such as ordering rate of doctor's advice on contact isolation for 24 hours,hand hygiene,health care workers' awareness all enhanced significantly(all P＜0.05).Conclusion Targeted monitoring and intervention measures can reduce isolation rate of MDROs in ICUs.

Objective To investigate the effects of different combinations of vitamin (Vit) C, Vit E and GSH on the biochemical markers and bone mineral density (BMD) in ovariectomized rats. Methods Seventy female SD rats aged 4 months were divided into two groups, 20 rats with sham operation in control group and 50 rats with bilateral oophorectomy in model group. 3 months later, 10 rats in the model group and 10 rats in the control group were randomly selected and their body weight, uterus weight, BMD of the left femurs and lumbar spines,biomeehanical characteristics of the left femurs, serum levels of Ca2+ , creatinine (Cr), alkaline phosphatase (ALP),superoxide dismutase (SOD) , malondialdehyde (MDA) , GSH-peroxidase (GSH-Px) and serum resisting abilities to OH- were determined. Then the rest rats were divided into five groups: A (sham), B (OVX control), C (Vit C +Vit E), D (GSH) and E (Vit C +Vit E +GSH). Vit C, Vit E and GSH were given 750rng/kg, 250 mg/kg, and 125 mg/kg, respectively daily for 3 months. And then the biochemical markers and BMD were measured. Results 3 months after treatment with antioxidants, BMD of left femurs and lumbars spines was increased, while the level of serum ALP was decreased markedly in B, C and D group as compared with that in B group. The serum level of SOD, GSH-Px and serum resisting ability to OH- were increased in D and E groups and the level of MDA decreased in C and D groups as compared with that in B group. Conclusion Vit C, Vit E and GSH increased BMD, prevented the decrease of SOD and GSH-Px and elevated serum resisting ability to OH-in ovariectomized rats.

Objective To investigate the effects of different combinations of antioxidants VitC, VitE and GSH on the biomechanical and biochemical markers in ovariectomized rats, Methods Seventy female SD rats, aged 4 months, were divided into 2 groups (control and model) randomly. Fifty rats in the model group underwent ovariectomy, while the other 20 rats in the control group had sham operations. Three month slater, 10 rats in the model group and 10 rats in the control group were selected randomly to detect their body weight, uterus weight, BMD of the left femur and lumbar vertebra, biomechanical characteristics of the left femur, levels of serum Ca2 +, Cr, ALP, SOD, MDA and GSH-Px and serumal resistance to OH<'->. Then the rest were divided into 5 groups: A (sham), B (model), C (VitC + VitE), D (GSH), and E (VitC + VitE +GSH). VitC, VitE and GSH were given in 750 mg/kg, 250 mg/kg, and 125 mg/kg every day for 3 months,respectively. And then the biomechanical and biochemical markers were measured. Results Three months after ovariectomy, the body weight of the rats in the model group increased markedly compared with the control group, while BMD of the left femur and lumbar vertebra, biomechanical maximal load and uterus weight decreased. The serum levels of Ca<'2+>, ALP and Cr increased. Three months after antioxidant treatment,the biomechanical maximal load and elastic load of the left femur and the maximal load of the 5th lumbar vertebra, the serum levels of SOD, GSH-Px and the serumal resistance to OH<'-> in groups D and E increased markedly, while the serum level of MDA decreased in groups C and D and the level of serum ALP decreased in all the treatment groups. Conclusion GSH and combination of VitC, VitE and GSH play a positive role in treatment of osteoperesis in ovariectomized rats.

Objective To explore the association between sleep quality and the increasing risk of type 2 diabetes mellitus (T2DM).Methods A total of 771 patients aged 25-70 years living in Xuzhou City of Jiangsu Province for at least 5 years were enrolled for the survey of risk factor related noninfectious chronic disease in 2013.In this investigation,those who suffered from other types of diabetes,neuropathy,other endocrine disease,cardiovascular,renal and hepatic dysfunction,dyspnea or cancer were excluded.To reduce the influence of confounding factors,another 771 participants were enrolled as controls.Each case was arranged to have a control who was matched in age (difference not more than 3 years),gender,residence and family history.All the participants were interviewed with self-designed questionnaire,and sleep quality was measured by Pittsburgh Sleep Quality Index (PSQI) questionnaire.Student's t test,Chi-square and multivariate logistic regression were used for data analysis.Results The PSQI score in the T2DM patients vs.the controls were 5.15±2.40 vs.2.71 ± 1.93 (t=21.96,P＜0.01).The scores of sleep-related factors,including subjective poor sleep quality,bedtime resistance,short sleep duration,sleep efficiency,sleep disturbance,use of sleep medication and daytime dysfunction,of the T2DM patients were higher than those of the controls.The proportion of sleep related behaviors of the T2DM patients was higher,except for early awakening,cold feeling and nightmare.Poor sleep quality was associated with the increasing risk of T2DM (odds ratio 2.06,95％ CI 1.69-2.52).In multivariate logistic regression,when adjusted for confounding factors,the risk of T2DM was still increased (odds ratio 1.72,95％ CI 1.62-1.83).Sleep-related factors (e.g.subjective poor sleep quality,bedtime resistance,short sleep duration,sleep efficiency and sleep disturbance) were correlated with the risk of T2DM (odds ratio was 3.34,1.63,1.10,1.87 and 3.89,respectively).Conclusion Low quality of sleep may be strongly associated with an increased risk of T2DM.

AIM: To determine the differences in phosphoproteome between LPS stimulated THP-1 cells with and without previous oxidative stress for screening of more potential regulators.METHODS: Differentiation of THP-1 cells into macrophages was induced by treatment with 100 ?g/L PMA for 36 h. Differentiated cells were rested for additional 36 h without PMA treatment, then treated with 100 ?mol/L H2O2 or medium for 1 h followed by LPS or medium treatment for 30 min. After desalted, phosphoproteins were enriched by phosphoprotein metal affinity column, and were run on 2-D electrophoresis, then the spots were analyzed to show the difference between LPS group (cells treated with LPS alone) and H2O2+LPS group (LPS stimulated cells also pretreated with H2O2). Finally, some of these spots were identified by MS and subsequent bioinformatic analysis was also conducted. RESULTS: Compared to LPS group, 29 reproducibly changed spots on the 2-D map in H2O2+LPS group were visualized and selected for MS analysis. Among these, 12 down-regulated spots (include those disappeared), 17 up-regulated spots (include those newly emerged) were selected. Up to now, 5 of these were identified, which were shown to be involved in various cellular processes such as proteolysis, signal transduction and protein folding. Among these, proteasome beta-4 subunit, which was dramatically down-regulated in H2O2+LPS group, was a major component of the proteasome complex and might participate in LPS signalling through various ways.CONCLUSION: With comparative phosphoprotein-affinity profiling, the interference brought by highly abundant house-keeping proteins is minimized, rendering us to detect less abundant signalling molecules. Aforementioned 5 proteins, especially proteasome beta-4 subunit, might be involved in LPS pathway reprogrammed by oxidative stress.
