Objective: To find out the infinity optical thickness of SY-1 silicone elastomers when color difference(△E) is equal to 1.5 . Methods: Silicone elastomer samples with thickness from 0.5 mm to 10 mm of SY-1 silicone elastomer were measured by CIE-1976-L *a *b * relative to CIE source against a white and a black background by using Minolta colorimeter . Color difference was calculated as △E=[(△L *) 2+( △a *) 2+(△b *) 2] 1/2 . The infinity optical thickness of SY-1 silicone elastomer when △E=1.5 was calculated by regression formulation. Result: When △E was equal to 1.5, the infinity optical thickness of SY-1 silicone elastomer was 7.60 mm. Conclusion: In order to get ideal effect the supports should be treated with colorant when the thickness of silicone elastomer covering the surface of supports in maxillofacial prostheses is thinner than 7.60 mm.

The association between fasting plasma ghrelin levels and insulin resistance and blood pressure (BP) in octogenarians was investigated in this study. A total of 487 unrelated octogenarians (including 203 men and 284 women) were enrolled in this cross-sectional study at the Healthy Care Center of Shanghai East Hospital, Tongji University, China, from October 2008 to April 2009. Plasma ghrelin was determined by using the enzyme linked immunosorbent assay (ELISA). Insulin sensitivity was assessed using the homeostasis model of assessment-insulin resistance (HOMA-IR). The age of the participants ranged from 80 to 89 years (mean=83.9+/-4.8 years) with a body mass index (BMI) of 25.3+/-4.9 kg/m(2). Plasma ghrelin levels were 20.94+/-5.34 mug/L, being 20.89+/-5.53 mug/L in men and 21.38+/-3.73 mug/L in women respectively. Plasma ghrelin was not associated with systolic (P=0.981) or diastolic (P=0.724) BP, waist circumference (P=0.278), fasting insulin (P=0.246), fasting blood glucose (FBG) (P=0.693) and HOMA-IR (P=0.232). In the control cohort, no significant differences in plasma ghrelin were found between genders (P=0.489), and among subjects with hypertension (BP>140/90 mmHg) (P=0.284) and type 2 diabetes (P=0.776). In conclusion, fasting plasma ghrelin levels are not directly correlated with insulin resistance and BP among octogenarians.

Using the animal model of acute myocardial infarction of rabbit after left coronary artery ligation, the authors studied the reltionship between the change of myocardial K~+/Na~+ ,Mg~(2+)/Ca~(2+), and Zn~(2+)/Cu~(2+) ratio and the time after acute myocardial infarction. The results demonstrated that. (1)the K+/Na~+ and Mg~(2+)/Ca~(2+)ratio dropped with prolongation of time myocardial ischemia. There was significant (P0.05)difference of Zn~(2+)/Cu~(2+) ratio between the experimental groups and the control group, but Zn~(2+)/Cu~(2+) ratio showed a tendency of dropping with prolongation of time of ischemia in the experimental group. At 120 min of myocardial ischemia,the Zn~(2+)/Cu~(2+) ratio was abour 1/2 as those at 15min, 30min, and 60min(P

Objective To investigate the clinical distribution and the drug resistances of Pseudomonas aeruginosa (PAE) during past 3 years in the 1st Affiliated Hospital of Kunming Medical University, and to provide evidence for clinical treatment of PAE infection.Methods The isolated PAE strains from 2010 to 2012 in the 1st Affiliated Hospital of Kunming Medical University were identified and antimicrobial susceptibility tests were performed using the MIC and the KB method,and thus, the ward distribution and the drug resistance rates and the changing trend were respectively analyzed by WHONET 5.5 software, and statistically analyzed with SPSS 17.0 SOFTWARE. Results Within the three years, a total of 208 strains, 260 strains and 280 strains of Pseudomonas aeruginosa were isolated separately in 2010,2011and 2012. A total of 746 PAE strains were isolated in 3 years,in which the most common specimens were sputum (79.8%), followed by the throat swab (7.6%) and the urine (6.2%) . When it came to the ward distribution , ICU was the primary, which accounted for (32.4%), followed by the department of cadre sanatorium (27.7%), the department of respiratory medicine (12.2%) and the department of neurosurgery (6.8%) . Besides imipenem, Cefoperazone-sulbactam and aztreonam, the others were obviously in a decreasing trend in drug resistances. In 2010, 2011 and 2012, the resistances rates of imipenem were ( 65.2%) , ( 74.2%) and ( 69.5%) , respectively, the resistances rates of Cefoperazone-sulbactam were (48.0%), (48.7%) and (55.8%), and the the resistances rates of aztreonam were (72.2%), (78.2%) and (72.4%) . Amikacin,piperacillin-tazobactam,Cefoperazone-sulbactam were the most active antimicrobial agents against P.aeruginosa. Conclusions The PAE is an important source of infection, ICUs are the focus of interest for resistance monitoring and control. Antimicrobial resistance of PAE is fairly serious. Clinicians should select appropriate antibiotic therapy based on sensitivity testing.The therapeutic strategy should he adapted according to the local ecology of resistance to control the epidemic of the drug- resistance strains and hospital infection.
