Objective: To investigate the relationship between vocabulary understanding ability and performance of theory-of-mind tests of children and to confirm the applicability of Chinese revision of Theory of Mind Tests in China. Methods: 100 children aged from 3 to 5 years in Harbin City in China completed the Chinese revision of Theory of Mind Tests and Peabody Picture Vocabulary Test(PPVT). Results:The pass rates of 'expression recognition' tests from 3 to 5 years groups were 100%, and that of 'expression reasoning' tests were 76%,97%,97%. There were 36%,76%,93% of children passed the 'place change' false belief tests and 15%,42%,59% of children passed the 'content change' false belief tests. From 3 to 5 years groups, significant differences of PPVT IQ were found between groups divided depending on different performances of false belief tests, such as that of children passed place change or not were 104.9?16.9 vs 97.0?15.8,106.7?17.6 vs 99.7?15.9(t=2.22,2.07, P

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 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.

Objectives To study the psychological characteristics of children with attention deifcit hyperactivity disorder (ADHD). Methods Human ifgure drawings (HFD) as a projective technique was performed in 107 children with ADHD aged (8.69 ±1.48) years old (6.5~11.5 years), and 107 matched healthy children. Characteristic features of the HFDs in children with ADHD, and correlations between emotional indicators of the HFDs and factors of child behavior checklist (CBCL) were assessed and com-pared with the control group. Results Signiifcant differences in emotional index were found between ADHD and healthy chil-dren, including bad body composition, short arms, long arms, big ifgure, omission of hands and omission of feet (P<0.05). Nega-tive correlation was found between the HFDs emotional index and the factors of activity and social ability in the CBCL (P<0.05), but a positive correlation was found between the HFDs emotional index and behavioral problem (P<0.05). Conclusion Human ifgure drawings can relfect some emotional characteristics of children with ADHD, and when combined with CBCL, it can pro-vide evidence for diagnosis and intervention for ADHD.

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.
