ABSTRACT
Radiotherapy is an important treatment of gynecological tumors. Although novel techniques or measures in recemy years have improved the tumor control rate and reduced radiation toxicity, radiation toxicity remains a major problem due to the location of some key organs adjacent to the tumor. A new material-hydrogel, as an organ spacer, provides a new method to reduce the radiotherapy toxicity. In this article, the application of hydrogel as an organ spacer in brachytherapy for gynecological tumors was reviewed from the aspects of hydrogel characteristics, suitable population, mode of injection, interval distance and dose effect, clinical benefits and cost effectiveness, etc.
ABSTRACT
Objective@#To explore the relationship of maternal adverse childhood experiences(ACEs) with mother child relationship, so as to provide reference for parent child relationship and child health promotion.@*Methods@#In June 2021, children aged 3-6 years old of 36 kindergartens in three areas in Anhui Province were selected by stratified cluster sampling method, follow up data were collected in December 2021, and a total of 6 111 children were included in the study. Maternal ACEs and mother child relationship were respectively assessed using the Adverse Childhood Experiences International Questionnaire(ACEs-IQ)and the Child Parent Relationship Scale (CPRS). A multiple linear regression model was established to analyze the association of maternal ACEs and mother child relationship in preschool children.@*Results@#History of maternal childhood sexual abuse, physical neglect and peer bullying were negatively associated with mother child intimacy ( r =-0.03, -0.03, -0.03, P <0.05). Maternal emotional abuse, physical abuse, sexual abuse, emotional neglect, physical neglect, peer bullying, community violence, and total family dysfunction were positively associated with mother child dependence and mother child conflict ( r =0.09, 0.08, 0.05, 0.14, 0.06, 0.11, 0.08, 0.04; 0.18, 0.17, 0.07, 0.20, 0.11, 0.16, 0.12, 0.10, P <0.01). There was no statistically significant between all types of maternal ACEs and mother child intimacy in boys( P >0.05). Mothers with a history of physical abuse, sexual abuse and peer bullying had a statistically significant relationship between mother child intimacy in girls( β =-0.17, -0.62, -0.19, P <0.05). All types of maternal ACEs were positive predictors of mother child conflict between boys and girls( β =0.37-1.96, P <0.05). There was statistical significance between maternal childhood sexual abuse and mother child dependence of boys( β =0.53, P <0.05), but no statistical significance between maternal childhood sexual abuse and mother child dependence of girls( P >0.05). All other types of maternal ACEs were positive predictors of mother child dependence( β =0.09-0.41, P <0.05).@*Conclusion@#Maternal ACEs are associated with poor mother child relationship among preschool children, and maternal ACEs should be actively followed, which is of great significance for improving the parent child relationship and promoting child healthy development.
ABSTRACT
Objective@#To explore the role of parenting style in the association of maternal adverse childhood experiences (ACEs) and emotional behavior problems (EBPs) in preschool children, so as to provide a reference for the prevention and control of EBPs in children.@*Methods@#A total of 6 111 children aged 3-6 years old from 36 kindergartens in 3 areas of Anhui Province in June 2021, follow up data were collected in December 2021. Maternal ACEs, mother child relationship and children EBPs were respectively assessed using the Adverse Childhood Experiences International Questionnaire(ACEs-IQ), Parental Rearing Style Scale and the difficulty score factor in the Chinese Strength and Difficulty Questionnaire(SDQ). The Bootstrap was used to examine the mediation effect of maternal parenting styles.@*Results@#Maternal ACEs were positively associated with child SDQ difficulty scores( r = 0.28, P <0.01). Negative parenting (indulgent, permissive, authoritarian and inconsistent) were positively correlated with maternal ACEs scores( r =0.28, 0.30, 0.21, 0.31) and child SDQ difficulty scores( r =0.25, 0.20, 0.20, 0.28)( P <0.01). Positive parenting (democracy) was negatively correlated with maternal ACEs and SDQ difficulty scores( r =-0.09, -0.29, P <0.01). After adjusting for confounding factors, the results of the mediation effect test of Bootstraping procedure showed that maternal parenting styles (indulgent, democracy, permissive, authoritarian and inconsistent) played a mediation role in maternal ACEs and EBPs of preschool children, and the mediation effects were respectively 19.13%, 7.34%, 24.88%, 12.05% and 26.83%.@*Conclusion@#Parenting styles play a mediating role in the association of maternal ACEs and EBPs in preschool children, and improving mothers negative parenting styles is of great significance to reduce EBPs in the offspring of maternal ACEs.
ABSTRACT
Objective@#To explore the relationship and gender difference between maternal adverse childhood experiences (ACEs) with emotional and behavioral problems (EBPs) in preschool children, and to provide a reference to promote emotional and behavioral problems among preschool children.@*Methods@#Using the method of stratified cluster sampling, 9 647 children from kindergartens in three cities of Anhui Province were selected in June 2021. Maternal adverse childhood experiences were investigated with the WHO Adverse Childhood Experiences International Questionnaire(ACEs-IQ), preschool children s emotional and behavioral problems were investigated with Strengths and Difficulties Questionnaire.@*Results@#The detection rate of abnormal emotional behavior was 17.4%, emotional symptoms 16.3%, conduct problems 18.3%, hyperactivity 22.7%, peer problems 34.2%, prosocial behaviors 18.5%. Multivariate Logistic regression analysis showed that maternal adverse childhood experiences were positively associated with the risk of emotional and behavioral problems ( OR =1.51-2.97, P <0.01). Maternal cumulative adverse childhood experiences were also positively associated with the risk of emotional and behavioral problems( OR =3.13-9.61, P <0.01). The association of maternal emotional abuse, physical abuse and community violence with peer problems were stronger in boys than that of girls ( ROR =1.25, 1.26, 1.41, P <0.05).@*Conclusion@#The findings suggest maternal adverse childhood experiences were associated with emotional behavior problems among preschool children. Focusing on the maternal adverse childhood experiences is crucial for the prevention and control of childhood emotional and behavioral problems.
ABSTRACT
Objective@#To explore the relationship and gender difference between family rearing styles with emotional and behavior problems in preschool children aged 3-6 years, so as to provide reference for early prevention and intervention of children s emotional and behavior problems.@*Methods@#Using the method of stratified cluster sampling, 9 647 children aged 3-6 years old from 36 kindergartens in Wuhu, Lu an and Fuyang of Anhui Province were selected in June 2021. Primary caregivers were investigated with self designed questionnaire, Strengths and Difficulties Questionnaire (parents version) and Parental Rearing Style Scale.@*Results@#The detection rate of elevated SDQ total difficulty score was 6.5%, with boys (7.1%) higher than that of girls (5.8%). The detection rate of abnormal emotional behavior were significantly higher in children with high scores on doting, laissez faire, autocracy and inconsistency of family rearing style, compared with those in the low score group ( χ 2=210.32, 203.87, 102.70, 212.69, P <0.01 ), and the detection rate increased with the increase of score. However, the detection rate of abnormal emotional behavior in the high score group of democracy was significantly lower than that in the low score group ( χ 2=156.24, P <0.01), and the detection rate decreased with the increase of score. Logistic regression analysis showed that high level doting ( OR =4.31), laissez faire ( OR = 4.16), autocracy ( OR =3.36) and inconsistency ( OR =4.76) of family rearing style were associated with high risk of children s emotional behavior problems, while high level of democracy ( OR =0.34) in family rearing style was associated with low risk of emotional behavior problems. The comparison between boys and girls showed that the risk of emotional and behavioral problems in the indulgent rearing style of boys was significantly higher than that of girls ( OR =1.90, 2.13) ( P <0.05).@*Conclusion@#Family rearing styles are associated with emotional and behavioral problems among preschool children. Boys are sensitive to the negative impact of doting rearing style. Good rearing styles is beneficial to the prevention and control of children s emotional and behavioral problems.
ABSTRACT
Objective:To investigate the sensitivity of the Catalyst HD in monitoring different skin colors, and assess the effect of skin color on the setup uncertainties using this system in radiotherapy.Methods:The standard cards guiding skin color and the cylinder model guiding quality control in radiotherapy were utilized to simulate the patients’ positioning. During the first monitoring, Catalyst HD was employed to acquire the image of the phantom as the reference image after conventional positioning (indoor laser+ phantom marking). When it was not the first monitoring, the couch was moved (-5 to 5 mm, step length of 2 mm) and Catalyst HD was adopted to obtain the surface image after conventional positioning. The bed deviation and corresponding setup errors monitored by Catalyst HD for different skin colors were recorded in the anterior-posterior (AP), superior-inferior (SI) and left-right (LR) direction, respectively.Results:During Catalyst HD monitoring, the integration time and gain were increased with the darker color. The logarithm of integration time and gain was significantly linearly negatively correlated with the same color ( R2>0.9). When the color difference with 1Y01SP was ΔE≤189, there was a significant correlation between the bed deviation and corresponding setup errors monitored by Catalyst HD in the SI and LR directions (R SI>0.5, R LR>0.5, R AP>0.9). The Catalyst HD monitoring was rapid and stable. When 218≤ΔE≤253, the correlation coefficients of them in the LR were R LR<0.3 and the Catalyst HD monitoring was stable. When 254≤ΔE≤285, the Catalyst HD failed to monitor stably. When ΔE>318, it failed to monitor this skin color. Conclusions:Gain, integration time and color have a certain correlation. The Catalyst HD can accurately monitor the setup errors within a specific range of skin color.
ABSTRACT
Objective@#To investigate the correlation between skin elasticity and setup error in optical surface image-guided radiotherapy.@*Methods@#The skin elasticity (R7) data of the head, chest and abdomen were extracted and analyzed its correlation with age by systematic literature review. Fifty-four patients diagnosed with nasopharyngeal carcinoma, breast cancer and cervical cancer were recruited in this study. Firstly, the patients were positioned based on the room laser and markers. Subsequently, the patient position was verified by the Varian On-Board Imager, and then C-Rad Catalyst was adopted to obtain surface images in two states (mask or non-mask) as reference images. In the subsequent fraction treatment, after initial positioning, the local calibration was performed by Catalyst, and setup errors in three directions were recorded. Meanwhile, the patient setup was verified by CBCT twice a week. The Pearson correlation analysis was performed to analyze the correlation between setup error and age.@*Results@#The skin elasticity was negatively correlated with aging (P<0.01). The correlation coefficient between random error and age in head-and-neck cancer were 0.645, 0.624 and 0.866 in the AP, SI and LR directions (all P<0.05) for male patients without mask, respectively. The system error was significantly correlated with age in the LR direction (P<0.05) for male patients, and in the AP direction (P<0.05) for female patients with head-and-neck cancer without mask. The setup error had a significant correlation with skin elasticity in male patients with head-and-neck cancer, and the sequence of absolute value of correlation coefficient was LR>SI>AP.@*Conclusion@#In optical surface-guided radiotherapy of head and neck cancer, skin elasticity may be a significant index for assessing the setup errors in male patients.

ABSTRACT
NMDA receptor has shown to be involved in several central nervous system disorders such as stroke, pain, parkinson′s disease, Huntington′s disease and epilepsy. Early studies revealed that NMDA antagonists produced adverse side effect that hampered the effort to develop NMDA antagonists. With advances in understanding the structure of NMDA receptor, NR2B antagonist is expected to be a more effective candidate with little side effect to treat these diseases. Several NR2B antagonists including CP 101, 606 are in preclinical trials in foreign countries. The present review summarizes progress in pharmacological actions of NR2B antagonists on neurodegenerative diseases.
