AIM: To investigate the effect of LY980503(a benflumetol derivative)on multidrug resistance of tumor cell line using DNA microarray. METHODS: Total RNA was extracted from multidrug resistant MCF/DOX cell line. cDNA microarray containing 320 cDNAs was used to detect the gene expression profile. RESULTS: 9 down-regulated genes and 1 up-regulated gene were identified after multidrug resistant MCF/DOX cells were treated with LY980503. CONCLUSION: LY980503 can effectively reverse the resistance of MCF/DOX to DOX in vitro by adjusting the expression of multi-genes.

Objective To investigate the efficacy and toxicities of gemcitabine and cisplatin as a chemother-apy regimen for patients with advanced non-small cell lung cancer (NSCLC). Methods Thirty-five patients with NSCLC were enrolled in this study. C, emeitabine was given on day 1 and 8 at a dose of 1000 mg/m~2 and cisplatin at a dose of 25 mg/m~2 on day 1 to 3. The chemotherapy was repeated every 28 days, after 2 cycles for evaluating response. Results Complete response (CR), partial response (PR) ,stable disease (SD) and progressive disease (PD) were observed in 0,14,16 and 5 cases, respectively, with a response rate (RR) of 40. 0%. The RR in initial treatment group was found more than that in the retreatment group (52. 2% vs 16.7% ,P<0. 05).The main toxicities were tol-erable, which included myelosuppression, nausea, vomiting, and liver damage. Conclusion Gemcitabine combined with cisplatin is effective and safe in the treatment of NSCLC, especially in the initial treatment patients.

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.

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.

Objective: To analyze the associations among body mass index (BMI), learning screen/gaming screen exposure and executive function in preschool children in Anhui Province, so as to provide a basis for promoting the development of executive function in preschool children. Methods: In June 2022, a stratified cluster sampling and convenience sampling methods were used to survey 3 534 mothers of preschool children in Wuhu City, Luan City, and Fuyang City, Anhui Province. The Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P) was used to assess the preschool childrens executive function abnormalities. Binary Logistic regression was conducted to examine the relationships among BMI, learning screen/gaming screen exposure, and their combined effects on executive function abnormalities. Results: The detection rate of abnormal executive function in preschool children was 9.65%. Logistic regression analysis showed that after adjusting for the confounding factors such as pregnancyinduced hypertension, primary caregivers, family per capita monthly income and family structure, the risk of abnormal executive function of children in overweight/obesity group and high learning screen/gaming screen exposure group increased significantly (overweight/obesity:OR=1.78, 95%CI=1.31-2.42, learning screen exposure:OR=1.48, 95%CI=1.18-1.86, gaming screen exposure:OR=1.50, 95%CI=1.18-1.91,P<0.05). Compared with children with normal BMI and low learning screen/gaming screen screen exposure, those with both overweight/obesity and high learning screen/gaming screen exposure had a significantly greater risk of executive function abnormalities (OR=2.07, 95%CI=1.29-3.31; OR=2.42, 95%CI=1.59-3.68,P<0.05). Conclusions Overweight/obesity and high learning screen/gaming screen exposure are important risk factors for executive function abnormalities in preschool children. Therefore, actively guiding preschool children to develop healthy life habits to promote the normal development of their executive functions is essential.

OBJECTIVETo explore the genetic etiology for fetuses with increased nuchal translucency (NT) but a normal karyotype at whole genome level by chromosome microarray analysis (CMA).

METHODSSeventy-eight fetuses with increased NT (≥ 3.0 mm) but a normal karyotype were collected between 11(+0) and 13(+6) gestational weeks. Genomic DNA was extracted, and microarray testing was performed using Affymetrix CytoScan(TM) HD arrays. The data was analyzed by CHAS software. All detected copy number variations (CNVs) were confirmed with real-time quantitative polymerase chain reaction.

RESULTSThe CMA assay has detected pathogenic CNVs in 6 fetuses (7.69%), which have ranged from 0.41 Mb to 15.87 Mb. Well-known microdeletion or microduplication syndromes including Wolf-Hirschhorn syndrome, 22q11 microdeletion syndrome and ATR-16 syndrome were identified in three cases. The detection rates in fetuses with or without structural abnormalities were 18.18% and 5.97%, respectively (P=0.198 with Fisher's Exact Test). The average NT in fetuses with pathogenic CNVs and non-pathogenic CNVs has measured 4.48 mm and 4.22 mm (P=0.735 by Mann-Whitney Test).

CONCLUSIONFor fetuses with increased NT, CMA can identify chromosomal microdeletion/microduplication unrecognizable by conventional karyotyping analysis. It may therefore play an important role in prenatal diagnosis and genetic counseling by improving the diagnostic rate.

OBJECTIVETo evaluate the effect of neonatal perioperative anesthetic exposure in complex cardiac surgery on neurodevelopmental outcomes in preschool children.

METHODSGeneral clinical data and data concerning anesthetic exposure were collected from 89 infants undergoing complex cardiac surgery at Sichuan People' Hospital. The cohort was followed for neurodevelopment till preschool age (48-72 months) and assessed with Wechsler Preschool and Primary Scale of Intelligence-III, Beery-Buktenica Developmental Test of Visual Motor Integration (VMI-V), and General Adaptive Composite (GAC) of the Adaptive Behavior Assessment System-II.

RESULTSSeventy-one children were enrolled into the final analysis. Multiple linear regression found days on benzodiazepines (beta;=-0.49, P=0.005) and cumulative dose of benzodiazepines (β=-0.10, P=0.023) were associated with the full-scale IQ in these preschool children. Days on benzodiazepines (beta;=-0.39, P=0.009) and on chloral hydrate (beta;=-1.19, P=0.020) were associated with lower performance intelligence quotient (PIQ) at the preschool age. Cumulative dose of benzodiazepine exposure (beta;=-0.008, P=0.012) was associated with lower VMI scores. No correlations of other sedation/analgesia variables were found with the full-scale IQ, PIQ, Verbal IQ, VMI, or GAC scores.

CONCLUSIONWe found a significant association of days on benzodiazepines, cumulative dose of benzodiazepines, and days on chloral hydrate in neonatal cardiac surgery with neurodevelopmental outcomes at the preschool age, suggesting the need of minimizing anesthetic exposure during a neonatal cardiac surgery to improve the children's neurodevelopmental outcomes.

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.

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.

OBJECTIVE: To determine the association between perioperative anesthetic exposure and neurodevelopmental status at age 1 year old baby underwent complex cardiac surgery.
 METHODS: One hundred and fifteen infants were selected from Sichuan People's Hospital. A cohort study was conducted on neonates who underwent complex cardiac surgery. The babies were performed brain MRI before the operation and 7 days after the operation, and 12-month neurodevelopmental testing was carried out with Bayley Scales of Infant and Toddler Development (the third Edition, Bayley-III). Doses of volatile anesthetics (VAA), benzodiazepines, and opioids were determined during the 12 months. The association between peri-operative anesthetic exposure and 12-month neurodevelopmental status were analyzed.
 RESULTS: A total of 92 infants were enrolled for the final analysis. Their Bayley-III scores of cognitive, language, and movement were as follows: 104.2 ± 14.7, 85.6 ± 11.3, and 86.9 ± 13.5, respectively. MRI results showed that 17 infants showed pre-operative brain injury and 25 infants showed new post-operative injury. After performing the analysis of stepwise multivariable linear regression, MRI showed the factors affecting neurodevelopment of newborn include the new post-operative injury, higher VAA exposure, fentanyl dose, benzodiazepine dose, ICU length of stay, pre-operative mean regional cerebral oxygen saturation (rSO₂), and abnormal chromosomes.
 CONCLUSION VAA exposure and ICU length of stay are associated with poor neurodevelopmental scores at 12 months of age. Further studies need to identify the potential modifiable factors in the peri-operative care of neonates to improve neurodevelopmental outcomes.
