[Current situation and related of overweight and obesity in children aged 3-6 years old in Urumqi City in 2021].

OBJECTIVE: To understand the current situation and related factors of overweight and obesity in children aged 3-6 years old in Urumqi City. METHODS: From October to December 2021, a questionnaire survey was conducted on the general information of 1897 children and their fathers or mothers from 10 kindergartens in Urumqi City by stratified cluster sampling, and the height and weight of the children were measured. SPSS 25.0 was used for χ~2 test and Logistic regression analysis. RESULTS: There were 1897 children out of which 961(50.66%) were boys, 936(49.34%) were girls, 334(17.60%) were 3 years old, 592(31.21%)were 4 years old, 667(35.16%) were 5 years old, and 304(16.03%) were 6 years old. The prevalence rate of obesity and overweight in children aged 3-6 years old was 31.21%(592). Single factor analysis showed that child's age, the child's sex, the child's dietary habits, whether the child's father had a family history of obesity, whether the child's mother had a family history of obesity, whether the child's mother suffered from hypertension during pregnancy, whether the child's father smoked, whether the child's mother smoked during pregnancy(including passive smoking), the child's family per capita monthly income, the child's family structure type, and the child's mother's pregnancy age were all statistically significant(P<0.05 or P<0.01). The logistic regression analysis showed that child's age, the child's sex, the child's dietary habits, whether the child's father had a family history of obesity, whether the child's mother had a family history of obesity, whether the child's mother suffered from hypertension during pregnancy, whether the child's father smoked, whether the child's mother smoked during pregnancy(including passive smoking), the child's family structure type, and the child's mother's pregnancy age were overweight and obesity children aged 3-6 years old of related factors in Urumqi(P<0.05 or P<0.01). CONCLUSION: The detection rate of overweight and obesity in children aged 3-6 years old in Urumqi City is high.

Impact of the COVID-19 pandemic on lifestyle and mental state in patients with schizophrenia: A retrospective study.

The corona virus disease 2019 pandemic's movement restrictions have an effect on people's lifestyles and mental health, and the most susceptible, such as persons with schizophrenia, are more subject to external influences. To analyze the lifestyle, anxiety, depression and stress status of inpatients with schizophrenia during corona virus disease 2019. A total of 205 patients with stable schizophrenia who were hospitalized during the epidemic period were selected. The general epidemiological information was recorded, and the depression screening scale (Patient Health Questionnaire-9), the Generalized Anxiety Disorder Scale-7, and the perceived stress scale were used to determine the mental status and stress level of the included patients. Restricted physical activity and perceptual bias might result in decreased food intake, higher body mass index, and increased psychotropic medicine dosages. According to Pearson correlation analysis, stress perception was positively connected with anxiety and depression scores. The anxiety score was positively associated with the depression score, indicating that stress influenced the patient's emotional alterations. During the pandemic, the lifestyle and psychological load of people with schizophrenia may be impacted. Medical personnel should be alert to changes in anxiety, depression, and stress in patients with schizophrenia and take appropriate action.

OBJECTIVES: To study the correlation between neck circumference and body mass index and the value of neck circumference in identifying overweight and obesity in preschool children. METHODS: The stratified cluster sampling method was used to recruit 3 719 children under 7 years from 10 kindergartens in Urumqi, China. General data were collected, and physical measurements were performed. A Pearson correlation analysis was used to evaluate the correlation between neck circumference and body mass index. The receiver operating characteristic (ROC) curve was used to assess the accuracy of neck circumference in identifying overweight/obesity. The Kappa consistency test was used to assess the consistency of neck circumference and body mass index in identifying overweight/obesity. RESULTS: There was a positive correlation between neck circumference and body mass index in boys and girls of all ages (r≥0.50, P<0.001). According to body mass index as the criteria for overweight/obesity, the children were divided into an overweight/obesity group and a non-overweight/obesity group, and the analysis showed that the overweight/obesity group had a significantly larger neck circumference than the non-overweight/obesity group (P<0.001). The ROC curve analysis showed that neck circumference had an area under the ROC curve of >0.7 in identifying overweight/obesity for boys and girls. The Kappa consistency test showed that the neck circumference and body mass index had a Kappa value of >0.40 in identifying overweight/obesity in boys and girls of all ages. CONCLUSIONS: Neck circumference is positively correlated to body mass index, and neck circumference can be used to identify overweight/obesity in preschool children.

Objective@#To understand the status quo and influencing factors of overweight and obesity in preschool children, and to provide scientific theoretical reference for the prevention and control of overweight and obesity in preschool children in Urumqi.@*Methods@#Stratified cluster sampling method was adopted to select 1 897 preschool children from 10 kindergartens in Urumqi from October to December in 2021 to understand the status quo of overweight and obesity of preschool children by measuring their height and weight. The influencing factors were collected by questionnaire survey, including Chinese preschoolers eating behavior questionnaire, Chinese preschooler s caregivers feeding behavior scale, 3-6 year old children s home nurture environment scale, and characteristics and influencing factors of physical activity among preschool children.@*Results@#The prevalence of overweight and obesity in preschool children was 31.21% (592), including 19.50% (370) overweight and 11.70% (222) obesity.Childhood overweight and obesity detection rates varied significantly by age, sex, child dietary habits, father BMI, maternal BMI, and maternal pre pregnancy BMI ( χ 2=19.63,28.75,9.45,18.21,18.45,19.36, P <0.05). Multivariate Logistic regression analysis showed that gender, children s eating habits, paternal BMI, pregnancy BMI, satiety responsiveness, external eating, initiative eating, weight concerns, behavior restricted feeding, physical activity and family physical activity environment were the influencing factors of overweight and obesity in preschool children( OR =0.52,1.43,1.51,1.44,0.69,0.74,1.35,1.71,0.81,0.96,1.10, P < 0.05 ).@*Conclusion@#Overweight and obesity in preschool children are popular in Urumqi. Education, diet control and scientific exercise should be strengthened to prevent childhood overweight and obesity.

Focal Adhesion Kinase Inhibitor Inhibits the Oxidative Damage Induced by Central Venous Catheter via Abolishing Focal Adhesion Kinase-Protein Kinase B Pathway Activation.

The vascular injury induced by central venous catheter (CVC) indwelling is the basis for the occurrence and development of CVC-related complications, such as phlebitis, venous thrombosis, and catheter-related infections. Focal adhesion kinase (FAK) and FAK-protein kinase B (AKT) signaling pathway are of great significance in tissue repair after trauma. Here, we investigated the role and mechanism of the FAK inhibitor (1,2,4,5-phenyltetramine tetrahydrochloride (Y15)) in oxidative damage caused by CVC. EA.hy926 cells were divided into the control group (normal control), CVCs+scratches group (the intercepted CVC segments coculturing with scratched EA.hy926 cells), and CVCs+scratches+Y15 group (Y15 was added to the cell culture supernatant with CVCs + scratches at a final concentration of 50 µmol·L-1). New Zealand rabbits were randomly divided into the control group (normal control), CVC group (CVC was inserted through the rabbit's right jugular vein to the junction of the right atrium and superior vena cava), and CVC+Y15 group (CVC was immersed in a 50 µmol·L-1 Y15 solutions before insertion). The levels of markers and proteins related to oxidative damage in cells, cell culture supernatant, serum, and external jugular vein were measured by commercial kits and western blot, respectively. We found that Y15 treatment significantly decreased ROS and MDA levels and increased cell viability, NO, and SOD levels in a time-dependent manner in rabbit serum and cell culture supernatant. In addition, Y15 effectively reduced the CVC-induced pathological changes of damaged vascular tissues. Y15 also downregulated the levels of p-FAK Tyr 397 and p-Akt Ser 473 in damaged external jugular vein and EA.hy926 cells. These findings suggest that Y15 alleviated CVC-induced oxidative damage to blood vessels by suppressing focal FAK-Akt pathway activation.

[Current status of neglect among children aged 3-6 years in rural areas of Urumqi, China and risk factors for child neglect].

OBJECTIVE: To investigate the current status of neglect in children aged 3-6 years in the rural areas of Urumqi, China and risk factors for neglect. METHODS: Stratified random cluster sampling was performed to select 1 326 children, aged 3-6 years, from 6 kindergartens in the rural areas of Urumqi. A self-designed questionnaire and "Chinese Neglect Evaluation Questionnaire for Rural Children Aged 3-6 Years" were used for investigation. RESULTS: Of the 1 326 children, the neglect rate was 51.89% (688 cases), and the degree of neglect was 49±6. There were significant differences in the neglect rate and the degree of neglect between the children in different age groups (P<0.01). The single-parent families and the remarried families had significantly higher child neglect rate and degree of neglect than the families of three generations under one roof and the core families (P<0.01). The children in left-behind status had a significantly higher degree of neglect (P<0.01). The multivariate logistic regression analysis showed that younger children, mothers with low education level, employment status of the mother as a migrant worker, single-parent and remarried families, low-income families, and left-behind status were risk factors for child neglect (P<0.05). CONCLUSIONS: The neglect of children aged 3-6 years in the rural areas of Urumqi is serious, and more attention should be paid to younger children, children whose mothers with low education level, left-behind children, and children from single-parent families, remarried families and low-income families.

[Current status of parental feeding behaviors in Urumqi, China, and its association with body mass index of children].

OBJECTIVE: To investigate the association between parental feeding behaviors and body mass index (BMI) of children, and to provide a scientific basis for the prevention and intervention of overweight and obesity in children. METHODS: Stratified random cluster sampling was used to select 976 children from 7 kindergartens in Xinshi District of Urumqi, and a questionnaire survey and physical measurement were performed to obtain related data. RESULTS: A total of 976 questionnaires were distributed and 924 (94.7%) usable questionnaires were collected. The overall detection rates of underweight, overweight, and obesity in children were 3.1% (29 children), 9.2% (85 children), and 6.7% (62 children), respectively. The highest level of parental feeding behavior was monitoring, followed by restriction and pressure to eat. The parents of the Han children had significantly higher levels of restriction and pressure to eat than those of the Uygur children (P<0.01). As for parental feeding behaviors, restriction to eat was positively correlated with BMI of the Han and Uygur boys (P<0.01); pressure to eat was negatively correlated with BMI of the Han boys and girls (P<0.01) and was positively correlated with BMI of the Uygur boys and girls (P<0.01); monitoring was negatively correlated with BMI of the Han and Uygur boys and girls (P<0.05). Among the parents of the Han and Uygur boys, the parents of the overweight/obese children had significantly higher scores of restriction to eat than those of the children with normal weight (P<0.05); among the parents of the Uygur boys and girls, the parents of the overweight/obese children had significantly higher scores of pressure to eat than those of the children with normal weight (P<0.01); among the parents of the Uygur and Han boys and girls, the parents of the overweight/obese children had significantly lower scores of monitoring than those of the children with normal weight (P<0.01). CONCLUSIONS: The parental feeding behavior is good in Urumqi, and the parental feeding behavior of the Uygur children is a little better than that of the Han children. Parental feeding behavior is closely correlated with BMI of children, and such correlation differs across ethnic groups and sexes. A high level of monitoring and low levels of restriction and pressure to eat may help to prevent and control the development of overweight and obesity in children.

[Current status of social anxiety and depression among primary school students in Urumqi, China].

OBJECTIVE: To investigate the current status of social anxiety and depression among the fourth-, fifth-, and sixth-grade students in Urumqi, China, and to provide data support for mental health education for primary school students in the future. METHODS: Stratified cluster random sampling was performed to select 919 fourth-, fifth-, and sixth-grade students from four primary schools for the Han and minority ethnic groups in Urumqi as research subjects. Social Anxiety Scale for Children and Children's Depression Inventory were used to evaluate the current status of social anxiety and depression. RESULTS: Among the 919 fourth-, fifth-, and sixth-grade students, the detection rate of social anxiety was 28.5% (262 students). The fourth-grade students had significantly lower scores on each subscale of social anxiety and total score of social anxiety than the fifth- and sixth-grade students (P<0.05). Girls had significantly higher score on the subscale of fear of negative evaluation and total score of social anxiety than boys (P<0.05). The Uyghur students had significantly higher scores on each subscale of social anxiety and total score of social anxiety than the Han students and the students of other minority ethnic groups (P<0.05). Among these fourth-, fifth-, and sixth-grade students, the detection rate of depression was 11.2% (103 students). The fourth-grade students had significantly lower scores on the subscales of negative self-esteem, ineffectiveness, and interpersonal problems and total score of depression than the fifth- and sixth-grade students (P<0.05). The Uyghur students had significantly higher scores on the subscales of anhedonia and negative mood and total score of depression than the Han students and the students of other minority ethnic groups (P<0.05). CONCLUSIONS: There are significant differences in the status of social anxiety and depression among the primary school students with different grades, sexes or ethnic groups in Urumqi. The fifth- and sixth-grade students, girls, and Uyghur students tend to have more serious psychological problems, which should be taken seriously by parents, schools, and the society.

Risk factors and community intervention for nonalcoholic fatty liver disease in community residents of Urumqi, China.

This study is to investigate the prevalence and risk factors of nonalcoholic fatty liver disease (NAFLD) and to analyze the effect of comprehensive community intervention on NAFLD in community residents in Urumqi, China.Cluster sampling method with street community as a unit was adopted in this study. Questionnaire survey, body measurement, blood biochemistry (including liver function, fasting blood glucose [FPG], and uric acid [UA]) examination as well as liver B ultrasound were performed. Then, comprehensive intervention was conducted in NAFLD patients.A total of 1000 people were enrolled, including 344 men and 656 women, with an average age of 51.79 ±â€Š4.28 years. Of them, 660 were Han Chinese, 327 were Uygur, and 13 were Hui. The overall prevalence rate of NAFLD was 54.3%. The prevalence rate of NAFLD is higher in middle-aged population and is higher in ethnic minority than that in Han. NAFLD was associated with the past medical history of metabolic diseases. The factors of body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), waist circumference, hip circumference, neck circumference, subcutaneous fat thickness, FPG, alanine aminotransferase, and aspartate aminotransferase were identified as risk factors for NFALD. Neck circumference predicts the occurrence of NAFLD in female better, whereas subcutaneous fat predicts the occurrence of NAFLD in male better. After 8 months of community intervention in NAFLD patients, the changes of BMI, SBP, DBP, waist circumference, neck circumference, subcutaneous fat thickness, and UA were statistically significant (P < .05).The prevalence rate of NAFLD is high in Urumqi, China. Community intervention is effective in reducing the degree of NAFLD and promoting the overall health of NAFLD patients.

Serum microRNAs as Early Indicators for Estimation of Exposure Degree in Response to Ionizing Irradiation.

Exposure to ionizing radiation from nuclear devices, spaceflights or terrorist attacks represents a major threat to human health and public security. After a radiological incident, noninvasive biomarkers that can facilitate rapid assessment of exposure risk in the early stages are urgently needed for optimal medical treatment. Serum microRNAs (miRNAs) are ideal biomarkers because they are stable in response to environmental changes, they are common among different species and are easily collected. Here, we performed miRNA PCR arrays to analyze miRNA expression profiles at 24 h postirradiation. Blood samples were collected from animals that received 0.5-2 Gy total-body carbon-ion irradiation. A specific signature with 12 radiosensitive miRNAs was selected for further validation. After exposure to 0.1-2 Gy of carbon-ion, iron-ion or X-ray radiations, five miRNAs that showed a significant response to these radiation types were selected for further observation of dose- and time-dependent changes: miR-183-5p, miR-9-3p, miR-200b-5p, miR-342-3p and miR-574-5p. We developed a universal model using these five miRNAs to predict the degree of exposure to different radiation types with high sensitivity and specificity. In conclusion, we have identified a set of miRNAs that are quite sensitive to different radiation types in the early stages after exposure, demonstrating their potential use as effective indicators to predict the degree of exposure.

miR-185 enhances the inhibition of proliferation and migration induced by ionizing radiation in melanoma.

Melanoma is an aggressive malignancy that is increasingly common and exhibits a poor patient survival rate. Radiotherapy is the primary option for patients with melanoma, particularly those who are not candidates for surgery; however, the therapeutic effect is limited due to the relative radioresistance of melanoma to ionizing radiation (IR). It has been reported that microRNAs (miRNAs) serve a vital role in determining the radiosensitivity of tumors; however, little is known concerning the radiosensitization of melanoma using miRNA. In the present study, the radiosensitization effect of miRNA 185 (miR-185), which has been demonstrated to reduce renal cancer radioresistance, was investigated in B16 cells, a skin melanoma cell line derived from C57/BL mice, was investigated. Cell proliferation and scratch wound healing assays were used to determine the proliferative and migratory abilities of B16 cells. Annexin V/propidium iodide double staining was used to determine the apoptosis induced by IR. A tumor formation assay was performed to determine the radiosensitization effect of miR-185 on melanoma cells in vivo. Proliferation marker protein Ki-67, and hematoxylin and eosin staining were used to assess the proliferative activity and histological changes, respectively. The results of the present study demonstrated that miR-185 suppresses cellular proliferation and migration, and enhances IR-induced apoptosis, and the inhibition of proliferation and migration, in vitro and in vivo, which provides an insight into understanding the radiosensitization of melanoma using miRNA.

Metabolic control with insulin pump therapy: preliminary experience.

BACKGROUND: The benefits of insulin pump therapy on the metabolic control of both type 1 and type 2 diabetes have been reported. Such reports have prompted our interest to investigate the long-term metabolic effects of insulin pump therapy at our institution. METHODS: We retrospectively analyzed the management of type 1 and type 2 diabetic patients who began extended insulin pump therapy at Changhua Christian Hospital between November 2004 and October 2007. One-way ANOVA and post hoc analysis were used to compare baseline glycosylated hemoglobin (HbA1C) values with subsequent values. RESULTS: We studied 12 patients who were on continuous subcutaneous insulin infusion (CSII) therapy at the time of data collection. Mean duration of CSII therapy was 2.3 years. A reduction in HbA1C was found after administering CSII, which was sustained after 1, 2 and 3 years of therapy (7.0%, 6.7% and 6.6%, respectively), with statistical significance (p<0.05). No incidence of severe hypoglycemia or diabetic ketoacidosis occurred during the treatment period. CONCLUSION: Our preliminary experience demonstrated the effectiveness of insulin pump therapy for both type 1 and type 2 diabetic patients. The reduction in their HbA1C values was both statistically and clinically significant. This treatment should be considered for patients poorly controlled by subcutaneous insulin injection therapy.
