BACKGROUND: The preparation and antibacterial activity of metal ionic zirconium phosphates has been systemically investigated now, but the applications are limited owing to the discoloration or the low antibacterial activity. Here we prepared new antibacterial agents of quaternized zirconium phosphates by introducing quaternary ammonium salt bactericidal agent with high-effective, broad-spectrum and low-toxic into sodium zirconium phosphate through an ion-exchange method.OBJECTIVE: To explore the component structure and antibacterial activity of quaternized zirconium phosphates.DESIGN, TIME AND SETTING: An in vitro observational experiment was performed at Research Laboratory of Department of Chemistry, Jinan University from June to August 2009.MATERIALS: Quaternized zirconium phosphates were prepared by introducing dodecyl dimethyl benzyl ammonium chloride into sodium zirconium phosphate through an ion-exchange method.METHODS: The mol ratios of quaternary ammonium cations to cation exchange capacity of sodium zirconium phosphate in reaction solutions were 0.25: 1,0.5: 1, 1.0: 1, and 1.5 : 1, respectively, and four kinds of quaternized zirconium phosphates containing different contents of quaternary ammonium cations (QZrP-1, QZrP-2, QZrP-3, QZrP-4) were prepared through an ion-exchange method.MAIN OUTCOME MEASURES: The component structure and heat resistance of samples were measured by using an IR spectrometer, an elemental analyzer and a thermal analyzer, respectively. The minimum inhibitory concentrations (MICs) and minimal bactericidal concentrations (MICs) of the samples against Escherichia coli (E. co/i) and Staphylococci aureus (S. aureus) were estimated by a tube broth method.RESULTS: Quaternized zirconium phosphates were prepared, and the quaternary ammonium cation content increased with increasing the concentration of quaternary ammonium cations in reaction solution. The mass fraction of quaternary ammonium cations of QZrP-1, QZrP-2, QZrP-3, and QZrP-4 was 3.70%, 5.00%, 6.96%, and 10.01%, respectively. The onset temperatures of the decomposition for quaternary ammonium cations in quaternized zirconium phosphates were all higher than 345 °C, and they were preferable thermal stability. The antibacterial activity was higher when the quaternary ammonium cation content of quaternized zirconium phosphates increased. For quaternized zirconium phosphates QZrP-3 containing 6.96% mass fraction of quaternary ammonium cations, showed excellent antibacterial activity against E. coli and S. aureus.CONCLUSION: Quaternized zirconium phosphates QZrP-3 containing 6.96% mass fraction of quaternary ammonium cations,exhibited excellent thermal stability and antibacterial activity.

Objective To determine the association between plasma concentrations of brain derived neurotrophic factor (BDNF), neuron-specific enolase (NSE), and S100β, and the occurrence of delirium in critically ill patients. Methods Totally 65 patients in Intensive Care Unit (ICU) of Wuxi People's Hospital of Nanjing Medical University between June 2015 and February 2016 were included in the present study. Delirium diagnosis was used by confusion assessment method for the ICU (CAM-ICU). Plasma BDNF, NSE, and S100β concentrations were determined on day 1(T1), 3(T3), and 10(T10) after ICU admission. The day of ICU admission was defined as T0. Results Compared with the plasma BDNF level on T1 (0.23±0.22) μg/L, the plasma BDNF level on T3 (0.59±0.34) μg/L and T10 (0.24±0.21) μg/L were higher, especially for that on T3 with a significant difference (F=21.58, P=0.018). Plasma NSE level on T3 (1.68±0.25) μg/L was significantly higher than that on T1 (1.22±0.32) μg/L (F=10.24, P=0.042). Compared with those without delirium, the delirious patients had lower BDNF, higher NSE and S100β on T1, T3 and T10, of which the difference of BDNF [T1: (0.23±0.22) μg/L vs. (1.02±0.24) μg/L, F=116.25,P<0.01; T3: (0.59±0.34) μg/L vs. (1.55±0.36) μg/L, F=82.39, P<0.01; T10: (0.24±0.21) μg/L vs. (1.09±0.55)μg/L, F=50.93, P=0.003, and NSE (T1: (1.22±0.32) μg/L vs. (0.47±0.23) μg/L, F=94.30, P<0.01;T3:(1.68±0.25) μg/L vs. (0.79±0.28) μg/L, F=78.63, P=0.017; T10: (0.98±0.37) μg/L vs. (0.51±0.22) μg/L, F=70.95, P=0.026) reached significant differences. Conclusions Plasma BDNF and NSE are closely related to the occurrence of delirium in critically ill patients, especially for BDNF. Clinical monitoring of plasma levels of BDNF can help to predict the outcome of brain function in critically ill patients.

Objective To investigate the level of platelet parameter of uterine cervical cancer patients and its clinical significance. Methods Seventy-four cases with cervical cancer (the observation group) from Ningde Municipal Hospital, the Affiliated Hospital of Fujian Medical University from May 2014 to May 2016 were chosen as the research subjects. Seventy-four cases of healthy people were treated as the control group. According to the International Federation of Gynecology and Obstetrics (FIGO), the observation group was divided into 15 cases under stage ⅡB(the early stage group), 59 cases of ⅡBstage and above (the middle and advanced stage group). Platelet count (Plt) and mean volume of platelet were monitored and compared by using Japan automatic blood cell analyzer. Results Plt in the observation group was higher than that in the control group [(266 ±71) × 109/L vs. (215 ±42) × 109/L, respectively], and the difference was statistically significant (t = 5.322, P< 0.05). The average volume of platelet in the observation group was lower than that in the control group [(9.2±1.2) fl vs. (9.9±1.3) fl, respectively], and the difference was statistically significant (t =-3.931, P < 0.05); There was no statistical difference in the Plt and mean volume of platelet between the early stage group and the middle and advanced stage group (both P>0.05). Conclusions The determination of platelet parameter has a certain clinical significance for screening and early detection of uterine cervical cancer.

Objective:To explore the performance of the commonly used whole blood C-reactive protein (CRP) detection systems and give related recommendation on the performance requirements of detection systems.Methods:A total of 7 540 venous blood samples from 26 maternal, child and children′s hospitals were collected to conduct this multi-center study on the analytical performance of 5 commonly used whole blood CRP detection systems from March to April in 2019. The blank check, carryover, repeatability, intermediate precision, linearity, sample stability, influence of hematocrit/triglyceride/bilirubin, comparison with SIEMENS specific protein analyzer and trueness were evaluated. The 5 systems included BC-5390CRP autohematology analyzer, AstepPLUS specific protein analyzer, Ottoman-1000 Automated Specific Protein POCT Workstation, i-CHROMA Immunofluorometer equipment Reader and Orion QuikRead go detecting instrument. The 5 systems were labeled as a, b, c, d and e randomly.Results:Within the 5 systems, all values of blank check were less than 1.00 mg/L, the carryovers were lower than 1.00%. The repeatability of different ranges of CRP concentrations including 3.00-10.00, 10.00-30.00 and>30.00 mg/L were less than 10.00%, 6.00% and 5.00%, respectively, and the intermediate precision was less than 10.00%. The linearity correlation coefficients of the 5 systems were all above 0.975, while the slope was within 0.950-1.050. Whole blood samples were stable within 72 hours both at room temperature (18-25 ℃) and refrigerated temperature (2-8 ℃). The CRP results were rarely influenced by high triglyceride or bilirubin, except for the immmunoturbidimetric test based on microparticles coated with anti-human CRP F(ab) 2 fragments. When triglyceride was less than 15.46 mmol/L, the deviation of CRP was less than 10.00%. When bilirubin was less than 345.47 μmol/L, the deviation of CRP was less than 10.00%. CRP was more susceptible to Hct on the systems without Hct correction. The deviation of CRP between different Hct dilution concentration and 40% dilution concentration can reach as high as 67.48%. The correlation coefficients ( r) of 5 systems were all more than 0.975 in the range of 0-300.00 mg/L compared with Siemens specific protein analyzer. All systems passed the trueness verification using the samples with specified values of 12.89 and 30.60 mg/L. Conclusion:The performance of 5 systems can basically meet the clinical needs, but it is suggested that the whole blood CRP detection system without automatic Hct correction should be modified manually.
