Objective To explore the effects of health education combined with WeChat′s public platform in the management of risk factors in patients with coronary heart disease. Methods A total of 100 coronary heart disease patients were randomly divided into intervention group and control group and there were 50 cases in each group by the random number table. The intervention group received health education about risk factors combined with WeChat′s public platform for 6 months. The control group received routine health education. Evaluate the control rate of blood pressure, blood glucose and blood lipid and the score of coronary heart disease self-management scale of the two groups before and after the intervention. Results At the 6th month after intervention, the control rate of blood pressure of the intervention group was 88.0％(44/50) and it of the case group was 70.0％(35/50).The difference between the 2 groups was statistically significant (χ2=4.882, P < 0.05). The score of coronary heart disease self-management scale of the intervention group was (102.44±8.22) points and it of the case group was (89.82±8.01) points . The difference between the 2 groups was statistically significant(t=7.776, P < 0.05). Conclusions The health education combined with WeChat′ s public platform contributed to help coronary heart disease patients to establish good self-management behavior and it can be widely used in the management of coronary heart disease risk factors.

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 screen out the individuals at high cognitive risk by using the weakest link theory,and explore the characters of the cognitive emotion regulation.Methods 600 undergraduate students were tested with cognitive style questionnaire,general social and academic hassles scale,center for epidemiologic studies depression scale,and cognitive emotion regulation questionnaire.Results There were significant differences between individuals of high and low cognitive risk in self-blame (13.32 ± 2.12) vs (12.45 ± 2.27),rumination,catastrophizing,blaming others,positive refocusing and positive reappraising.Catastrophizing,generality,rumination,positive reappraising,stress,self-blame,and self could predict 34.2％ of depression.Conclusion There are differences between individuals of high and low cognitive risk in cognitive emotion regulation.Catastrophizing,generality,rumination,positive reappraising,stress,self-blame,and self are the main predictors of depression.

Objective To investigate the correlation of serum anti-M-type phospholipase A2 receptor (PLA2R) antibody with laboratory parameters of idiopathic membranous nephropathy (IMN) in adult patients with membranous nephropathy (MN),and to explore the role of anti-PLA2R antibody in the pathogenesis of IMN. Methods Forty-six adult patients with biopsy-proved glomerular diseases were involved in this study,including 20 cases with IMN,7 cases with IgA nephropathy (IgAN),6 cases with hepatitis B-associated membranous nephropathy (HBV-MN),6 cases with minimal change nephropathy (MCN),4 cases with focal segmental glomerulosclerosis (FSGS) and 3 cases with class Ⅴ lupus nephritis.Total RNA was extracted from human glomeruli and was reversely transcribed to the first-strand cDNA.The full-length human M-type PLA2R was amplified by PCR and the 605 bp product was subcloned into eukaryotic expression vector containing CMV promoter.The recombinant human M-type PLA2R plasmid vector was transiently transfected into human embryonic kidney (HEK) 239T cell line using the FuGene6 transfection reagent.Western blotting was used to detect serum anti-PLA2R antibodies.Correlations of antiPLA2R antibody level with laboratory parameters,including serum albumin,total cholesterol,Scr and 24-hour urine protein,of IMN patients were evaluated. Results Among 20 cases with IMN,15 cases showed positive anti-PLA2R antibodies (positive rate 75％).Of 7 cases with IgAN and 6 cases with HBV-MN,only 1 case showed positive anti-PLA2R antibody respectively (positive rate 14.29％ and 16.67％ respectively).Anti-PLA2R antibody was negative in other patients.The positive rate of anti-PLA2R antibody in IMN patients was significantly higher than that in patients with secondary MN and other types of glomerlonephritis (all P＜0.01).Furthermore,anti-PLA2R antibody level was positively correlated with 24-hour urine protein(r=0.803,P＜0.01) and negatively correlated with serum albumin in IMN patients (r=-0.816,P＜0.01). Conclusions The high positive ratio of anti-PLA2R antibody may indicate that it is the specific autoantibody in IMN.AntiPLA2R antibody is correlated with IMN disease severity,which indicates that it may be the pathogenic autoantibody in IMN.

Objective To construct a genetically-stable double auxotrophic,in which the uracil and leucine were mutated,using the Candida parapolymorpha ATCC26012 as materials.Methods Based on the physical and genetic engineering methods,the chromosome of the C.parapolymorpha strain was modified,where the ura3 and leu2 genes were directly mutated,to obtain the uracil and leucine double auxotrophic strain.Then the constructed strain was identified by the analysis of its biological properties,such as genetic stability,the change of the genes,and the physiologic and biochemical characteristics.Results The uracil and leucine double auxotrophic strain is obtained by screening.The biological identification results show that the obtained strain is genetically stable and the targeted genes are directly altered.In addition,the physiologic and biochemical analyses indicate that the auxotrophic can utilize various kinds of carbon and nitrogen nutrient sources,and its growth is good.Conclusion The successful construction of double auxotrophic mutant strains facilitated the genetic studies on C.parapolymorpha to meet various investigational purposes.Moreover,the constructed auxotrophic strains can be applied as advantageous host cells to express multiple proteins/antigens simultaneously,which is of great significance in the development of vaccines.

?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.
