Objective To analyze the difference of salivary microbiome between the patients with functional dyspepsia and healthy controls.Methods Saliva samples were collected from the patients with functional dyspepsia and healthy control.Genomic DNA of the samples was extracted,and the high-throughput sequencing technology was used to conduct DNA sequence of 16S rRNA-V4 region.Subsequently,all the data were performed by the bioinformatic analysis.Results The salivary microbiome in the functional dyspepsia group was dominated by Proteobacteria,while Bacteroidetes was the top microbiota in the heathy control group.In the functional dyspepsia group,the Chao1 index,ACE index,Shannon index and Simpson index were 1 295,1 351,4.93 and 0.90 respectively.In the healthy control group,the above indexes were 1 001,1 351,5.28 and 0.92 respectively.The PCoA ba sically separated the microbiome composition of the two groups.Sixteen kinds of microbiota were significantly different between two groups using linear discriminant analysis effect size tool,including Bacteroidetes,Prevotella,Prevotellaceae,Neisseria,Betaproteobacteria and Proteobacteria,etc.Conclusion Saliva in the patients with functional dyspesia has characteristic microbiome composition,which is dominated by Proteobacteria,but the richness and diversity between the two groups have no difference.Neisseria is one of the significantly different bacteria between the two groups.

Objective To observe the clinical safety of dual axis rotational coronary angiography (DARCA) in the diagnosis of coronary artery disease in Chinese population.Methods From March to December in 2010,74 patients undergoing diagnostic DARCA were enrolled.The improved isocentering technique was adopted in 34 of the patients at the end of the study during DARCA.Blood pressure,heart rate and symptoms were recorded immediately before-and-after contrast injections.Contrast dose,radiation exposure and procedure time for DARCA were recorded.Continuous variable data were analyzed using Student＇s t test,if normality assumption was violated,rank sum test would be used.Categorical variables were analyzed using x2 test.Results ( 1 ) Clinical safety:There was no chest pain documented during or immediately post-injection for all patients.Only 1 patient ( 1 ％ ) had an attack of ventricular tachycardia immediately after the contrast injection and then relieved automatically.Pre and post-injection systolic blood pressure values of left coronary artery were statistically different [ ( 116 ± 20 ) mm Hg vs.( 111 + 18) mm Hg( 1 mm Hg =0.133 kPa),t =3.303,P =0.001 ],and heart rates differed,too [ 73 ( 65- 84)bpm vs.71(64-78) bpm,Z =-4.789,P =0.001 ],but that imposed no clinical significance.(2)Contrast dose,radiation dose and procedure time:The mean contrast utilization,radiation dose and procedure time for DARCA were 28 (25-34) ml,8979 ( 6733-12 363 ) mGycm2 and 200 (164-270) s.Compared with conventional DARCA,improved isocentering technique during DARCA had less radiation exposure and procedure time in left coronary artery angiography and the whole coronary artery angiography [ left coronary artery angiographic radiation exposure:4004 (2932-5772) mGycm2 vs.5808 (4798- 8838) mGycm2,Z =-3.471,P =0.001 ;total radiation exposure:(8116 +2493) mGycm2 vs.( 11 371 ±4122) mGycm2,t =-4.176,P =0.001 ; left coronary artery angiographic procedure time:120 ( 80-180)s vs.150(126-214) s,Z =- 2.836,P =0.005; total procedure time:180 (139-240) s vs.220( 186-308 )s,Z =-3.004,P =0.003 ],but there was no statistically difference in contrast utilization [30(25-35) ml vs.27(25-34)ml,Z=-0.906,P=0.365].Conclusion This study demonstrates clinical safety of DARCA in the diagnosis of coronary artery disease in Chinese population.Compared with conventional isocentering technique of DARCA,improved isocentering technique can significantly reduce radiation exposure and procedure time on the basis of simplified operation,and replace the conventional isocentering technique,but randomized double-blind controlled studies should be conducted.

Objective: To explore the relationship between parental self efficacy consistency with children s social development,and to provide a reference basis for promoting children s social development. Methods: During September to October of 2019, cluster sampling method were used to select 905 children and their parents from 2 kindergarten (senior , mid and junior class) and 2 primary schools (grade one to grade three) in Bengbu. Children s social development and parental self efficacy were assessed by the Strengths and Difficulties Questionnaire(SDQ) and the parenting sense of competence Scale, respectively. Ordinal Logistic regression was used to analyze the relationship between parenting efficacy consistency with children s social development. Results: Prevalence of emotional problems, conduct problems, hyperactivity attention inability，peer problems, and abnormal prosocial behtavior was 8.95%，6.30%， 18.01%, 14.03%，7.40% and 5.41%，respectively, which were negatively associated with parental self efficacy( P <0.01). Consistent parenting sense of competence, children s emotion, hyperactivity attention inability, moral behavior and prosocial behavior anomaly detection rate lowest, mother parenting self efficacy were higher than the father, children s enotion, conduct behavior, hyperactivity attention inability and prosocial behavior anomaly detection rate is highest, when the father parenting self efficacy was higher than that of mothers, Children s conduct behavior and hyperativity attention inability had the highest detection rate( Z =6.57, 7.58,7.25, 7.06, P <0.05). Children with higher maternal parenting self efficacy were more likely to develop emotional, conduct behavior, hyperactivity attention inability and prosocial behavior abnormalities, and children with higher father parenting self efficacy were more likely to develop conduct behavior and hyperactivity attention inability ( P <0.05). Conclusion Parental self efficacy and its consistency are related to child social development.It is suggested that parents should improve the parenting efficiency and the quality of companionship, optimize the family relations, and create a harmonious atmosphere.

Objective: To understand the current situation of the social development between only children and firstborn of young age, so as to provide a reference for the promotion of the social development of young children. Methods: Stratified cluster sampling method was used to select 734 only children and firstborn children aged 3-9 in two kindergartens and two primary schools from grade 1 to grade 3 for questionnaire survey in Bengbu City. The content included the general information of children and their parents and the social assessment of children. Results: The rate of emotional symptoms in firstborn children(27.8%) was higher than those of only children (17.6%)( χ 2=9.45, P <0.01). The results of univariate analysis showed that the rate of hyperactivity and inattention in social development of both only children and firstborns decreased with the increase of family socioeconomic status ( P < 0.05 ). Multivariate Logistic regression analysis of only children showed that only children with high economic status had a lower risk of hyperactivity and inattention and had a higher risk of peer interaction( P <0.05). The prosocial behavior of girls was better than that of boys in the aspect of social development of only children and firstborn children( OR =1.70, 2.85, P <0.05). For only children, the occurrence risk of being difficult was lower when the primary caregiver was parents than grandparents( OR =1.63, P < 0.05 ). For firstborn children, the risk of being difficult in nuclear families was lower than that in third generation families( OR = 2.14 , P <0.05). Multivariate analysis of the only child showed that boys had higher risk of hyperactive attention and less prosocial behavior than girls ( OR =2.24, 1.70, P <0.05), and a lower risk of developing mood disorders than girls( OR =0.57, P <0.05). The social development of only children varied among different grades, and the risk of abnormal prosocial behavior was lower with the increase of grades ( P <0.05). Conclusion Higer family social status is positively associated with children s social development level. But parents with high economic status should also avoid too much material and spiritual doting. Parents should strengthen their own learning to enhance the level of socialized education, raising siblings equally, improve the quality of parent child relationship, and promote the all round development of children s socialization level.

Objective: To understand aggressive behavior and associated family determinants of firstborn and only children in primary school, so as to provide the basis for child aggressive behavior prevention. Methods: Using stratified cluster sampling method, 922 pupils from grade 2 to grade 6 were selected from three primary schools in Bengbu. The questionnaire survey included general information, family background and child aggressive behaviors. Results: Among boys, the 7 year old only child scored [26.0(22.0,34.5)] higher than firstborn children [20.0(17.5,26.5)] in overall aggression, and the 9-year-old firstborn child [ 27.5 (23.0,34.3)] scored higher than the only child [23.0(18.5,28.5)]. The scores of 8-year-old firstborn child in the dimension of physical aggression [7.0(4.0,11.0)] were higher than that of only child [5.0(3.0,8.0)] ( Z=1.97, 2.39, 2.11, P < 0.05 ). Among girls, 8-year-old only child scored higher [5.0(3.0,7.0)] in the dimension of physical aggression than that of the firstborn child [ 3.0 (3.0,4.0)], and the 12-year-old firstborn child scored [7.0(6.0,8.0)] higher in the dimension of hostility than that of the only child [4.5(3.3,9.0)] ( Z=2.48, 1.98, P <0.05). Multiple linear regression analysis found that boys of firstborn children scored higher in all dimensions of aggressive behavior than those of girls except hostility, and paternal education was negatively associated with physical aggression and hostility ( P <0.05). Age was positively associated with verbal aggression among the only children ( P <0.05). Family economic status was negatively associated with physical aggression ( P <0.05). Paternal education was negatively associated with hostility among students with anger and hostility of family members higher than that of parents ( P < 0.05 ). Conclusion Higher family economic status, high quality of parent company and appropriate parenting style can reduce the occurrence of children s aggressive behavior and promote healthy physical and psychological development.

Objective: To explore the moderating role of estradiol in the relationship between parenting styles and preschool children's behavioral problems, so as to provide a theoretical basis for improving the development of human s emotional health development in early life stage. Methods: During September to November in 2022, 354 children aged 3-6 years and their parents from two kindergartens in Bengbu City were chosen by using stratified cluster sampling method for the questionnaire survey. The Parenting Style Scale and the Child Behavior Checklist (CBCL) were used to collect information on parenting style and child behavioral problems. Salivary estradiol of children was collected and tested. Independent samples t test was applied to compare the scores of the scale for parental up bringing and children s behavioral problems, and Pearson correlation analysis was conducted to explore the relationship among parental upbringing, estradiol and children s behavioral problems. Results: Parents doting, laissez faire, autocratic, and inconsistent parenting styles were positive associated with child behavior problems( r =0.14-0.70); fathers democratic parenting style was negatively associated with child behavior problems( r =-0.14，-0.22，-0.21，-0.17，-0.27，-0.20); mothers democratic parenting styles was negatively correlated with scores on all five dimensions of child behavior problems except the withdrawal dimension ( r =-0.14，-0.12，-0.13，-0.21，-0.12)( P <0.05). Estradiol levels had significant moderating effects on maternal doting parenting style and children s withdrawal ( β =0.68) as well as social problems ( β =-1.00), also moderating laissez faire parenting styles and children s withdrawal problems ( β =0.75)( P <0.05). For children with low levels of estradiol, withdrawal problem scores were negatively associated with mother s doting parenting style and positively associated with laissez faire parenting style, and socialization problem scores were associated with mother s doting parenting style; for children with high levels of estradiol, withdrawal problem scores were positively associated with mother s doting parenting style, and socialization problem scores were associated with mother s doting parenting style ( t=2.84, 6.24, 3.16 , 2.37, 4.49, P <0.05). Conclusions Parenting styles are strongly associated with child behavioral problems; estradiol levels play a moderating role in mothers doting, laissez faire parenting styles and children s withdrawal problems and social problems.Parents should adopt more positive parenting styles and focus on the role of estradiol levels in maternal education to reduce the occurrence of behavioral problems in children.

Objective To investigate the influence of WeChat + family centered health intervention on the self-efficacy of elderly hypertensive patients in General clinic. Methods A total of 102 elderly hypertensive patients aged≥60 years in General clinic from February 2017 to July 2017 were enrolled.They were divided into experimental group and control group with the table of random number, with 51 cases in each group. The experimental group used the WeChat+ family centered health intervention model,while the control group adopted the traditional health education model.The changes of blood pressure and self-efficacy were evaluated before intervention, 3 months and 6 months after intervention respectively. Results There were no statistic significant difference in blood pressure and self-efficacy total score between the two groups before intervention(P>0.05). At 3 months after intervention,the blood pressure(systolic pressure/diastolic pressure)of the patients were(144.20±4.60), (80.00±5.00)mmHg(1 mmHg=0.133 kPa)in the experimental group,those of which were(154.20±7.16), (87.00±3.81)mmHg in the control group,the differences were statistically significant (t=-2.628,-2.490,P<0.05).At 6 months after intervention,the blood pressure(systolic pressure/diastolic pressure)of the patients were(141.60±6.43),(76.00±4.85)mmHg in the experimental group,those of which were(151.60± 5.94),(85.40±4.56)mmHg in the control group,the differences were statistically significant (t=-2.555,-3.158,P<0.05).There were differences in systolic and diastolic pressure in patients with different groups at different time,and the differences were statistically significant(F=18.668,18.174,P<0.01).The total score of self-efficacy at 3 months and 6 months after intervention was(30.14±0.43),(32.56±0.23)points in the experimental group and (28.14 ± 0.15), (29.40 ± 0.19) points in the control group, the difference was statistically significant(t=9.736, 23.819, P<0.05). The differences in the total score of patients′self-efficacy in different groups at different time had statistically significance (F=2 631.551, P<0.01). Conclusions The WeChat+family centered health intervention model can significantly improve the self-efficacy of the elderly patients with high blood pressure in the General clinic.

Objective: To assess the effect of health coaching on interventional effect in high-risk population of stroke. Methods: A baseline survey was conducted among 897 residents aged 40 years and above selected by cluster sampling method in a community of Shijiazhuang city from January 2016 to June 2016, and 178 subjects were identified as high risk population of stroke. The high-risk subjects were randomly divided into two groups: the control group (n=89) was given routine health education, while the intervention group (n=89) received health coaching based on motivational interview for 13 months. The behavioral risk factors and self-efficacy scores were compared between two groups before and after intervention. Results: There were no significant differences in behavioral risk factors between the two groups: for hypertension 72 vs. 74 cases (χ²=0.152, P=0.67), for hyperglycocemia 44 vs.48 cases (χ²=0.360, P=0.55), for dyslipidemia 62 vs. 60 cases (χ²=0.104, P=0.75), for smoking 35 vs.32 cases (χ²=0.215, P=0.64), for obesity 50 vs.52 cases (χ²=0.092, P=0.76), for lack of exercises 72 vs.70 cases (χ²=0.139, P=0.71), for atrial fibrillation 14 vs. 16 cases (χ²=0.160, P=0.19). And there was no significant difference in self-efficacy scores between the two groups [(5.3±1.2) vs. (5.6±2.0), t=0.997,P=0.32]. After intervention, there were significant differences between the two groups in behavioral risk factors: for hypertension 25 vs. 34 cases (χ²=19.984, P<0.05) , for hyperglycaemia 16 vs.32 cases (χ²=8.448, P<0.05) , for dyslipidemia 30 vs. 48 cases (χ²=13.216, P<0.05) , for smoking 20 vs.28 cases (χ²=7.583, P<0.05) , for obesity 18 vs.38 cases (χ²=14.158, P<0.05) , for lack of exercises 28 vs. 36 cases (χ²=10.235, P<0.01) , for atrial fibrillation 5 vs. 13 cases (χ²=6.451, P<0.05) . And the self-efficacy scores of intervention group were higher than those of control group[ (8.4±2.1) vs. (6.8±2.2), t=4.852, P<0.01]. Conclusion Health coaching based on motivational interview is beneficial to reduce risk factors and improve self-efficacy in high risk population of stroke, which is worthy of popularization.
