Objective To investigate the epidemiological characteristics and risk factors of non-alcoholic fatty liver disease in Jincheng between 2015 and 2020. Methods Clinical data of 8,578 medical check-ups at Physical Examination Center of ou hospital from January 2015 to December 2020 were retrospectively selected. The prevalence of non-alcoholic fatty liver disease in the last 5 years was recorded, and Logistic regression was utilized to identify the risk factors for the development of non-alcoholic fatty liver disease. Results The overall prevalence of non-alcoholic fatty liver disease in Jincheng was 14.57% in 2015-2020. The prevalence of non-alcoholic fatty liver disease was higher in men than in women (16.99% vs 10.98%) and highest in the 40-59 age group (18.76%). No statistical difference was reported in blood urea nitrogen (BUN) and serum creatinine (Scr) between groups (P>0.05), while statistical difference was found in diabetes, hypertension, body mass index (BMI), waist circumference, weekly exercise frequency, daily vegetable intake, triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT) and uric acid (UA) between two groups (P<0.05). Multivariate Logistic regression analysis denoted that BMI (OR=2.794, 95% CI: 1.745-4.550), waist circumference (OR=2.586, 95% CI: 1.585-4.299), diabetes (OR=0.644, 95% CI: 1.425-2.781), hypertension (OR=1.479, 95% CI: 1.121-2.290), weekly exercise ≥6h (OR=0.617, 95% CI: 0.519-0.709), daily vegetable intake ≥300g (OR=0.590, 95% CI: 0.467-0.652), TG (OR=1.481, 95% CI: 1.122-1.996), TC (OR=1.562, 95% CI:1.143-2.135), LDL-C (OR=1.440, 95% CI: 1.139-2.048), HDL-C (OR=0.656 , 95% CI: 0.587-0.783) , ALT (OR=1.591, 95% CI: 1.056-2.183), and UA (OR=1.412, 95% CI: 1.009-1.887) were risk factors for non-alcoholic fatty liver disease (P<0.05) . Conclusion The prevalence of non-alcoholic fatty liver disease in Jincheng City from 2015 to 2020 is 14.57%, the prevalence of males is higher than that of females, and the prevalence rate is the highest in the 40-59 age group. Moreover , diabetes mellitus , hypertension , BMI , waist circumference , weekly exercise , daily vegetable intake , serum TG, TC, LDL-C, HDL-C, ALT, and UA are all associated with the risk of the disease.

Objective To measure the anatomical parameters of the first maxillary molars in children of different age groups and evaluate the age-related changes in dental crowns.Methods A retrospective analysis was conduc-ted on cone beam computed tomography(CBCT)images of 4-8-year-old children.NNT software was used to ana-lyze multiple important indicators of maxillary first molar.Results A total of 308 first maxillary molars,including 154 pediatric patients,were evaluated in this study.The thickness of the pulp apex H1(left,P=0.01;right,P=0.02)and the thickness of the pulp chamber floor H3(left and right P＜0.01)were positively correlated with age,while the height of the pulp cavity H2(left and right P＜0.01)and the height of the palate tip D1(left P=0.003,right P=0.002)showed a negative correlation with age.There was no significant correlation between the height of the buccal tip and age(P＞0.05).There were significant differences in H1 and H3 between the 4-year-old and 5-year-old age groups between the 8-year-old age group(P＜0.05),as well as significant differences in H2 and D1 between the 4-year-old and 5-year-old between the 6-year-old,7-year-old and 8-year-old age groups(P＜0.05).Conclusion The age-related changes in the crowns of the first maxillary molars are important references for the clinical treatment,and can be accurately measured through CBCT data.

Objective To evaluate and compare the treatment efficacy between concentrated growth factor(CGF)and blood clots(BC)as scaffolds in regenerative endodontic procedures(REPs).Methods Twenty young permanent teeth from 18 healthy children with pulp necrosis or periapical periodontitis were randomly divided into CGF group and BC group.In the CGF group(n=10),after ap-ical bleeding,CGF was inserted into the root canal as a stent.In the BC group(n=10),by stimulating apical bleeding,blood entered the root canal and produced blood clots as scaffolds.Clinical examination and apical X-ray shooting were conducted for each follow-up visit.Cone beam computed tomographic(CBCT)images were acquired preoperatively and at the 24-month recall.The increase of root length,root wall thickness,and newly-formed calcified tissue were calculated.Results The root length increased by(1.68±0.90)mm in the CGF group and(2.36±1.34)mm in the BC group.Root wall thickness increased by(0.44±0.34)mm in the CGF group and(0.50±0.31)mm in the BC group.There was no statistically significant difference in root lengthening and root wall thickening between two groups(P＞0.05).The amount of newly formed calcified tissue in the CGF group((22.13±19.12)mm3)was significantly less than that in the BC group((42.97±22.69)mm3)(P＜0.05).According to the goals for success outlined by American Association of Endodontists(AAE),90%(9/10)of the CGF cases and100%(10/10)of the BC cases achieved the primary and secondary goals(P＞0.05).40%of the CGF cases(4/10)and 60%of the BC cases(6/10)achieved the tertiary goal(P＞0.05).Conclusion CGF is found to be use-ful as a scaffold for REPs,but the success rate is slightly lower than that of BC group and the difference is not statistically significant.

Objective:To understand the identification value of pointing gestures in children with autism spectrum disorder(ASD) and its relationship with functional development.Methods:From December 2020 to November 2021, 1 099 children from Children’s Health Care Center of Beijing Children’s Hospital were tested by pointing gestures test, including 942 ASD children and 157 typical developed children.And the data of children's neuropsychological development scale from 800 children aged 1.0-5.9 were collected.SPSS 20.0 was used for statistical analysis. Trend test was used to analyze the distribution of pointing gestures test sensitivity in autistic children, and ANOVA was used to analyze the relationship between pointing gestures test scores and functional development fields.Results:The sensitivity of pointing gestures was 83.5% in children aged 1.0-10.0 years, 76.3%-93.1% in children aged 1.0-4.9 years, and 93.1%-95.1% in children aged 1.0-2.9.With the increase of age, the sensitivity of pointing gestures in autistic children (linear-by-linear association =164.889, P<0.001) and the Yoden index had a decreasing trend. The positive predictive value (91.53%-100.00%) and negative predictive value (75.36%-91.84%) were found in the children aged 1.0-10.0 years.The sensitivity of pointing gestures test was 44.9% in children with mild autism aged 1.0-10.0 years and 46.5%-65.9% in children with mild autism aged from 1.0-3.9 years. The sensitivity of pointing gestures test was 81.5% in children with moderate autism aged from 1.0-10.0 years and 87.3%-97.8% in children with moderate autism aged 1.0-3.9 years. The sensitivity of the pointing gestures test was 97.2% in children with severe autism aged 1.0-10.0 years, and 100.0% in children with severe autism aged 1.0-3.9 years. The sensitivity of the pointing gestures in mild, moderate and severe autism children decreased with age (linear-by-linear association values were 16.725, 64.232, 66.732 respectively, all P<0.001). The children with severe autism mainly scored 2 points (80.3%, 419/522) on the pointing gestures test , and children with moderate autism mainly scored 1 point(64.2%, 170/265) on the pointing gestures test. There were significant differences in functional development among different pointing gestures test groups.Functional development score in the autism children with 0 score of pointing gestures test was significantly higher than those with 1 score and 2 scores of pointing gestures test (all P<0.05). Conclusion:Pointing gestures has good sensitivity in children with autism (especially 1.0-4.9 years of age), and may serve as an objectively observable screening method. The better children with autism score on the pointing gestures, the better their functional development.

Objective: To explore the relationship between abuse experience with suicidal ideation and suicide attempts of junior middle school students, and to provide a reference for suicide prevention of junior middle school students. Methods: Cluster sampling method were used to selct 10 289 junior middle school students from 25 districts and counties of Chongqing were included in the analysis of this study from July to September in 2020. And Questionnaire on Abuse in Childhood and Mental Health Scale for Middle School Students were applied to collect the data about demographic information, suicide ideation and behavior. Results: The prevalence of suicidal ideation and suicide attempts among junior middle school students were 20.93% and 10.83%, respectively. Multivariate Logistic regression model found that after controlling for demographic variables and mental health, emotional abuse ( OR =2.07) and emotional neglect ( OR =2.03) showed higher correlations with suicidal ideation than the other three types of childhood abuse( OR physical neglect =1.19, OR physical abuse =1.60, OR sexual abuse =1.37, P <0.05); and sexual abuse ( OR =2.29) and physical neglect ( OR =1.87) showed higher associations with suicide attempt than the other three types of abuse( OR emotional abuse =1.63, OR emotional neglect =1.59, OR physical abuse =1.50, P <0.01). Conclusion All five types of child abuse were independent risk factors for suicidal ideation and suicide attempts, and emotional neglect and emotional abuse had a greater effect on suicidal ideation, sexual abuse and physical neglect had a greater effect on suicide attempts.

Objective:To investigate the correlation between social and linguistic parenting behaviors and developing capability of children with autism.Methods:From August 2020 to December 2020, the social and linguistic parenting behaviors of 302 parents of children diagnosed with autism were investigated in the outpatient department of the hospital.Meanwhile, the data of Gesell scale for children, the social life competence scale for infant and junior middle school students, the autism behavior checklist and the Cancy autism behavior scale were collected.SPSS 20.0 software was used for statistical analysis.Independent sample t test and analysis of variance were used to compare the social and linguistic parenting behaviors of different parents.Pearson correlation analysis was used to analyze the correlation between the social and linguistic parenting behaviors of parents and children's developmental ability and symptom severity. Results:There were no statistically significant differences in children's social and language development parenting behavior between father and mother ( t=1.033, P=0.303; t=-0.312, P=0.756). There were no statistically significant differences in children's social and linguistic parenting behaviors between fathers of different age groups ( F=1.425, P=0.244; F=1.127, P=0.345). Among mothers of different age groups, the social parenting behaviors of <30 years old and 30-34 years old groups were significantly better than those of 35-39 years old group ( F=3.374, P=0.019; LSD: P=0.010, P=0.006). Among fathers, the social parenting behavior( F=4.346, P=0.008; LSD: P=0.020, P=0.001) and social + linguistic parenting behavior in the graduate group and college group were significantly better than those in the high school/vocational group( F=3.965, P=0.012; LSD: P=0.020, P=0.002). Among mothers, the social parenting behavior ( F=2.812, P=0.040; LSD: P=0.008, P=0.023, P=0.009), linguistic parenting behavior ( F=3.769, P=0.011; LSD: P=0.010, P=0.025, P=0.001), social + linguistic parenting behavior ( F=3.654, P=0.013; LSD: P=0.005, P=0.015, P=0.002) in graduate and above groups were significantly better than those in college group, high school/vocational group, junior high school and below groups.The scores of social parenting behavior(40.72±6.80), linguistic parenting behavior(27.20±5.22), and social + linguistic parenting behavior(67.92±11.10) were significantly correlated with children’s fine motor(61.75±16.41)( r=0.193, P=0.001; r=0.153, P=0.009; r=0.190, P=0.001), cognition(68.28±16.83)( r=0.231, P=0.000; r=0.186, P=0.001; r=0.229, P=0.000), language(53.01±18.55) ( r=0.262, P=0.000; r=0.305, P=0.000; r=0.304, P=0.000) and social self-care(61.44±17.85) ( r=0.264, P=0.000; r=0.238, P=0.000; r=0.274, P=0.000). The scores of linguistic parenting behavior and social + linguistic parenting behavior were correlated with children's social life ability (8.65±0.89) ( r=0.142, P=0.046; r=0.140, P=0.049). There was no significant correlation between social parenting behavior, linguistic parenting behavior, social + linguistic parenting behavior and the scores of ABC scale (50.53±21.39) ( r=-0.089, P=0.336; r=-0.115, P=0.215; r=-0.107, P=0.250) and CABS scale (13.96±4.54) ( r=-0.050, P=0.490; r=-0.059, P=0.411; r=-0.058, P=0.421). Conclusions:The social and linguistic parenting behaviors are related to their age and educational level, and are significantly correlated to developing capability of children with autism, but have nothing to do with the severity of children's symptoms.

Objective:To evaluate the effectiveness of mentorship-Leichester assessment package (LAP) model in general practice teaching.Methods:Sixty five-year Traditional Chinese Medicine (TCM) students undergoing general medicine internship from July 2020 to December 2020 were divided into study group and control group with 30 students in each group. Students in study group undertook general practice internship in Fangzhuang Community Health Service Center with the mentorship-LAP model, including group-based teaching, weekly LAP case discussion and mentor-intern individualized LAP clinical practice teaching; students in control group undertook general practice internship in other community teaching bases with the traditional clinical practice training methods. After one month, students were evaluated with LAP score sheet and the evaluation results were compared between two groups.Results:After one month of training, the scores of medical history collection, physical examination, problem solving, patient management, doctor-patient relationship, expected care and medical records in both groups increased compared with pre-training (the control group: t=4.23, 5.06, 8.94, 4.85, 3.99, 1.04, 5.13, study group: t=1.86, 2.85, 12.42, 13.61, 6.29, 4.83, 5.63, all P<0.05). The scores of medical history collection, physical examination, problem solving, patient management, doctor-patient relationship, and expected care after training in the study group were higher than those in the control group ( t=5.66, 2.83, 5.67, 8.13, 2.76, 2.52, all P<0.05). After the training, in the medical history collection items, the scores of patient-centered communication, RICE recognition, and physical-psychological-social factors in study group were higher than those in the control group ( t=5.66, 7.35 and 2.66, all P<0.05); in the problem-solving items, the scores of clinical data application, comprehensive analysis ability and personal ability limitation in study group were higher than those in the control group ( t=4.32, 3.38 and 2.26, all P<0.05); in the patient management items, the scores of overall management plans, doctor-patient collaboration, dispelling doubts, subsequent visits/follow-up, and the degree of patient understanding the management plan in the study group were higher than those in the control group ( t=3.03, 2.07, 2.43, 3.15 and 2.17, all P<0.05). Conclusion:The mentorship-LAP teaching model is helpful to improve the effectiveness of general practice internship for medicine students.

Objective:To analyze the clinical value and predictive difference of serum Golgi protein 73 (GP73) and serum autophagy-related protein p62 levels in the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure (ACLF).Methods:Clinical data of admitted cases to our hospital from October 2018 to April 2020 were retrospectively analyzed. Simultaneously, there were 32 cases with HBV-related ACLF in group A, 65 cases with hepatitis B virus-related cirrhosis in group B and C (Child-Pugh Class A, 34 cases as B group, and Child-Pugh B/C class, 31 cases as group C), and another 30 healthy subjects served as the control group (group D). The serum GP73 and p62 levels of the four selected groups were measured. ACLF group patients were followed up for 3 months to analyze the prognosis of the patients. The serum GP73 and p62 levels of patients who died and survived during hospitalization were compared. The data were analyzed by one-way analysis of variance, independent sample t-test, and Pearson’s correlation analysis. Receiver operating characteristic curve (ROC) was used to analyze the predictive value of GP73 and p62 levels in surviving patients.Results:GP73 levels in the four groups A, B, C and D were (284.30 ± 70.55) ng/ml, (125.33 ± 20.57) ng/ml, (159.82 ± 31.20) ng/ml, and (45.46 ± 10.22) ng/ml, respectively. The p62 levels were (1.30 ± 0.35) ng/ml, (2.88 ± 0.58) ng/ml, (2.02 ± 0.545) ng/ml, and (4.68 ± 1.03) ng/ml, respectively. GP73 detection value was significantly higher in group A than the other three groups ( P < 0.05). Group D had significantly lower value than the other three groups ( P < 0.05), and group C had significantly higher value than group B ( P < 0.05). The detection value of p62 in group A was significantly lower than the other three groups ( P < 0.05). Group D had significantly higher value than the other three groups ( P < 0.05), and group B had slightly higher value than group C, and the differences were statistically significant ( P < 0.05). There was a negative correlation between GP73 and p62 ( r = -0.695, P < 0.001). Survived patients GP73 level in the ACLF group was significantly lower than dead patients [(212.17 ± 22.47) ng/ml and (340.08 ± 32.91) ng/ml, t = 12.493, P < 0.05], and p62 level was significantly higher than dead patients [(1.46 ± 0.28) ng/ml and (1.18 ± 0.35) ng/ml, t = 2.445, P < 0.05]. According to the ROC curve analysis results, the area under the curve (AUC) of GP73 was 0.865, the AUC of p62 was 0.750, and the combined AUC of the both was 0.968. Conclusion:Both GP73 and p62 have a certain predictive value for the short-term prognosis of HBV-related ACLF patients, but the combination of the two indicators has a higher predictive value.
