Comparison of emotional and behavioral problems of preschool children in only child and multiple child families / 中国学校卫生

Objective@#To explore the emotional and behavioral problems of different only child and multiple child families, and to provide a reference for developing effective parenting styles.@*Methods@#A stratified random cluster sampling method was adopted to investigate 2 647 guardians of preschool children in Tongling City from April to June, 2022. Children s emotional and behavioral problems were evaluated by using the self designed parenting questionnaire and the Children s Strengths and Difficulties Questionnaire (SDQ) parent edition.@*Results@#The abnormal total score detection rate of emotional and behavioral problems of preschool children was 15.5%, and the rate of abnormal peer interaction was the highest (19.5%). In multiple child families, the first born child (17.5%, 20.4%), compared with the second and third child (11.5%, 9.5%), was more likely to exhibit conduct and hyperactivity problems ( χ 2=8.44, 29.75, P <0.01). There were differences in parenting attitudes between only child and multiple child families( χ 2=9.38, P <0.05). The results of the Logistic regression analysis showed that more frequent parent child discussion, the persuasive education and consistent family discipline strategy were negatively related to the emotional and behavioral problems of only children and children in multiple child families ( OR =0.15, 0.49, 0.38; 0.34, 0.40, 0.42, P <0.05). However, harmonious family relationships were only negatively related to emotional and behavioral problems in only children ( OR =0.08, P <0.01), and a higher education level among mothers was negatively related to emotional and behavioral problems in children from multiple child family environments( OR=0.30, 0.45, P <0.05).@*Conclusion@#The emotional and behavioral problems are serious of preschool children in Tongling City, the psychological development of the oldest children from multiple child and only child families should be actively followed, as this would help to promote a better understanding of the development of preschool children s physical and mental health.

Relationship between sLR11 level,type 2 diabetes and carotid CIMT / 中国糖尿病杂志

Objective To investigate the relationship and clinical significance between circulating soluble low-density lipoprotein receptor family member 11 (sLR11) level,type 2 diabetes (T2DM) and carotid intima-media thickness (CIMT). Methods Newly diagnosed patients with T2DM (T2DM group,n=55)and healthy controls (NC group,n=55)were enrolled in this study. The sLR11 level was measured by ELISA. The level of sLR11,CIMT,age,blood lipid,and blood pressure were compared between the two groups. Another 165 patients with T2DM treated with conventional pharmaceutical medications were also selected in this study. The relationship between sLR11,CIMT and atherosclerosis were analyzed. The influences of sLR11 and FPG in the progress of CIMT were also evaluated. Results The sLR11 level and CIMT were higher in T2DM group than in NC group [(8.35 ± 2.65) vs (6.64 ± 1.99)ng/ml,P= 0.026;(0.87 ± 0.37) vs (0.73 ± 0.26) mm,P= 0.037]. In the 165 patients with T2DM,the level of sLR11 and CIM T were(9.79 ± 3.54)ng/ml and (0.79 ± 0.18)mm respectively. Correlation analysis showed that sLR11 levels were positively correlated with age,systolic blood pressure, LDL-C,fasting plasma-glucose (FPG),and HbA1c (r = 0.226,0.162,0.166,0.276,0.176). Multivariate linear regression analysis indicated that FPG was an independent risk factor for sLR 11 (β=0.175,P<0.05),and sLR11 was a independent risk factor of CIMT in the absence of age factor (β=0.008,P<0.05). Conclusion The sLR11 level may relate to blood glucose in T 2DM,and reflect the situation of CIM T and the pathological status of vessel intimal smooth muscle cells (SMCs).

Epidemiological study on leptospirosa infection of host animals and healthy population in flood areas / 中南大学学报(医学版)

OBJECTIVE@#To investigate the infection of leptospirosa of host animals and the immune level of healthy population in flood areas.@*METHODS@#Korth culture was used to culture leptospira for rodent kidney and oxen urine sample. The serogroups of leptospira and leptospira antibody were tested by microscopic agglutination test (MAT).@*RESULTS@#In flood regions, draw-near-flood region, and new migration region, rodent density was 6.95%, 6.28%, and 8.67%, respectively. The positive rates of rodent with leptospira was 4.63%, 1.35%, and 3.13%, respectively. Leptospira positive rates of oxen urine were 5.88%, 5.98%, and 1.75%, respectively. The main serogroup of leptospira was Icterhamorrhagic and Canicola serogroup. The positive rates of leptospirosa antibody in healthy population was 45.91%, 62.30%, and 58.67%in these 3 regions respectively, which was significantly higher than the average level in China. The dominant serogroups of leptospira in health population were icterhamorrhagic, autumnalis, canicola, pomona and bataviae. The positive rate of antibody had no difference among different age groups.@*CONCLUSION@#The main host animals are rodents and oxen infected with leptospira and the positive rate of leptospira antibody is high in healthy population in the study area. The dominant serogroups in host animals are similar to that in healthy population, which is mostly icterhaemorrhagic.

Research on automatic recognition system for leucocyte image / 生物医学工程学杂志

The image segmentation method we use for leucocytes is based on image distance transformation, combining the region and edge approach, taking full advantage of image information. According to the shape, texture and color appearance of cells, we select 22 feature values and measure them. The classifier is designed on the statistical classification. A test for recognizing 831 leucocytes in 560 images shows that the classification accuracy is 96%. Clinical experts confirm this system; for it can automatically recognize leucocytes by pattern recognition technique, and it is demonstrably valid in practice.
