International Journal of Laboratory Medicine 2014;(11):1470-1470,1473
Objective To compare the results of three methods for measuring C reaction protein.Methods 100 patients were collected from our hospital,and three different methods for measuring C reaction protein were used to analyze the level of C reaction protein.Results Correlation analysis showed that the correlation between immunoturbidimetric assay and immunochromatography was higher.The differences of three methods assayed the C reaction protein were significant (P <0.05 )among normal people by the variance analysis,but had not statistical significance among abnormal people (P >0.05).The differences among all of test peo-ple were significant(P <0.05).Conclusion Detection of C reaction protein was important for diagnose inflammatory diseases.

OBJECTIVETo evaluate the effects of Yili dark bee propolis on the main cariogenic biofilm and mechanisms.
METHODSSusceptibilities to the ethanolic extract of propolis against Streptococcus mutans (S. mutans), Streptococcus sobrinus (S. sobrinus), Streptococcus sanguis (S. sanguis), Actinomyces viscosus (A. viscosus), and Actinomyces naeslundii (A. naeslundii) were analyzed by crystal violet stain method to determine the minimum biofilm eradication concentration (MBEC). The biofilm was initially cultivated for 24 h. Subsequently, the propolis groups with different concentration MBEC and initial pH 7.0 were cultured for 24 h. Moreover, the pH value was measured to evaluate the acid-producing ability of the tested plaque biofilm. The effects of propolis on the insoluble extracellular polysaccharide synthesis of S. mutans biofilm were evaluated by anthrone method.
RESULTSThe MBEC of Yili propolis on S. mutans, S. sobrinus, S. sanguis, A. viscosus, and A. naeslundii were 6.25, 1.56, 3.13, 0.78, and 0.78 mg.mL-1, respectively. Propolis could decrease the ΔpH of the tested plaque biofilm, and the differences between the control and propolis groups were statistically significant (P<0.05). At MBEC, propolis could reduce the ability of S. mutans in synthesizing insoluble extracellular polysaccharides.
CONCLUSIONYili propolis demonstrate remarkable eradicative effects on the cariogenic plaque biofilm, showing inhibition of the synthesis of biofilm-produced acids and insoluble extracellular polysaccharides.

OBJECTIVE:To optimize the formulation of indomethacin-loading solid lipid nanoparticle(SLN). METHODS:Us-ing indomethacin as model drug,glyceryl behenate as oil phase,poloxamer 188 and polyethylene glycol-12-hydroxystearic acid as emulsifier,with turbidity,entrapment efficiency and drug loading amount as index,Box-Behnken response surface methodology was used to optimize the amount of oil phase,emulsifier-oil phase ratio,drug-oil phase ratio. The physicochemical properties of SLNs were characterized by SEM and DSC. RESULTS:The optimal formulation was as follows as oil phase of 0.91%,emulsifier-oil ratio of 1∶1,drug-oil phase ratio of 1∶5. The turbidity,entrapment efficiency and drug loading amount of prepared nanoparticle were 1 025-1 030 NTU,98.94%-99.08%,2.43%-2.46%,respectively;particle size and polydispersity index(PDI)were 181.5-182.3 nm and 0.340-0.341(n=3). The results of DSC showed that indomethacin was not present in crystalline state dispersed into SLNs. CONCLUSIONS:The optimal formulation is screened successfully,and indomethacin-loaded SLNs have been prepared.

Objective To review retrospectively our experience of the diagnosis and surgical treatment in patients with abdominal aortic aneurysm(AAA).Methods The diagnosis and surgical treatment in 72 patients 〔62 men, 10 women; mean age (67.5?9.3) years)〕 with AAA from January 1995 to February 2004 were analyzed. Fifty eight patients with infrarenal AAA and 2 patients with suprarenal AAA underwent elective graft replacement operation; 12 patients with ruptured AAA underwent urgent graft replacement operation. Results Fifty eight patients with infrarenal AAA and 2 patients with suprarenal AAA were cured and 2 patients with infrarenal AAA died of multiple organ failure after elective graft replacement operation, the 30 day mortality rate in patients with infrarenal AAA after elective operation was 3.45%. Seven patients were cured and 5 patients died of multiple organ failure after urgent graft replacement operation, the 30 day mortality rate was 41.67%. Conclusion The elective graft replacement operation in patients with AAA is a safe and effective surgical approach under the improvement of surgical technique and management of perioperative period.

?Advances in genome-wide analysis have revealed that up to 90%of the human genome is transcribed.However, only approximately 1% of RNA transcripts encode proteins, and the remaining transcripts are noncoding RNAs.Noncoding RNAs can be roughly divided into small noncoding RNAs (<200nt ) and long noncoding RNAs ( LncRNAs, >200nt ). Small noncoding RNAs include microRNAs, transfer RNAs and small nucleolar RNAs, whereas the long noncoding RNAs comprise ribosomal RNA, natural antisense transcripts, etc. Although the biosynthesis and biological activities of microRNAs are well studied through bioinformatics and active biological molecules analysis, the understanding of LncRNAs on these aspects is still limited.LncRNAs play multiple roles in regulating gene transcription and translation, and epigenetics.Aberrant LncRNAs expression can occur in various pathological processes and significantly related to the pathogenesis or poor prognosis of ophthalmological diseases. In this review, we will focus on the characteristics and regulatory functions of LncRNAs that are commonly associated with ophthalmological diseases.

Objective To explore the integrity of white matter changes in patients with vascular mild cognitive impairment (VaMCI)based Leukoaraiosis.Methods The patients which appeared white matter hyperintensities in subcortical were performed psychological testing,then 48 VaMCI patients and 18 without cognitive impairment volunteers(NC)were choosed and performed DTI scanning,to determine the white matter’s values of FA and ADC in the following bilaterally symmetrical regions of interest(ROI):entorhinal cortex lobe,hippocampal vault,anterior of corpus callosum,posterior of corpus callosum,inferior frontal lobe,superior temporal lobe and angular gyrus of occipital lobe. Then the differences of the data of DTI between two groups and the relevance between neuropsychological score and DTI’s data were analysed.Results ADC values were significantly higher of VaMCI group in the left inferior frontal lobe,left anterior of corpus callo-sum,left hippocampus vault and right angular gyrus compared with NC group(P <0.05),and in the left hippocampus ADC values and MoCA scores was negatively correlated(r=-0.34,P =0.02).There was no significant difference of FA values between groups. Conclusion The ADC values in many cognitive related areas was reduced in VaMCI patients.

Objective Searching for natural anticariogenic agent has become a focus at home and abroad.The aim of this study was to evaluate the effect of Yili dark bee propolis on the main cariogenic bacteria . Methods ①The minimum inhibitory concentration (MIC) of Yili dark bee propolis on oral common cariogenic bacteria was detected by the liquid diffusion method.②The four different con-centrations lower than MIC were used to confect culture media with pH 7.0 and the normal culture media was used as control group .The pH and the changes of pH (ΔpH) were evaluated to detect the effect of Yili dark bee propolis on acid producing ability of tested bacteria .③The effects of propolis on extracellular polysaccharides synthesis of S.mutans and A.viscosus were evaluated by anthrone method. Results①The MIC of Yili dark bee propolis on S.mutans, S.sobrinus, S.sanguis, L.acidophilus, A.viscosus and A.naeslundii were 0.78, 0.39, 1.56, 0.39, 0.2, 0.2 mg/mL, respectively.The minimum bactericidal concentrations were 1.56, 0.78, 3.125, 0.78, 0.39 and 0.39 mg/mL.②The propolis could decrease theΔpH of tested bacteria, and the differences between propolis groups and control group were statis-tically significant (P<0.05).③The propolis could reduce the ability of S.m and A.viscosus synthtic extracellular polysaccharides at MIC, and the differences were significant (P<0.05). Conclusion Yili propolis could inhibit the growth, acid producing ability and polysac-charides synthesis of the main cariogenic bacteria to some extent, and it could be deemed as a natural anticariogenic agent.
