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.

Objective To conduct an epidemiological survey of common congenital heart disease(CHD)among children in ethnic minority areas in southeastern Guizhou and to explore the influencing factors of delayed medical treatment.Methods From January 2019 to July 2022,18 850 children aged 3 months to 14 years in Qiandongnan Miao and Dong Autonomous Prefecture were selected;105 children with CHD were included in the training set,and they were divided into delayed group(80 cases)and non-delayed group(25 cases)according to whether or not to delay medical treatment.In addition,children with CHD(35 cases)from July 2022 to December 2022 were included in the validation set.The general data of the subjects in the two groups were compared and ana-lyzed.Multivariate logistic regression was performed and risk scoring model was constructed.Results The preva-lence of CHD in 18 850 children was 5.57‰(105/18 850),with the highest prevalence in Liping County,and the lowest in Huangping County.The proportion of children with secondary atrial septal defect was the highest,and that of the aortic valve malformation was the lowest.Among the complex cases of CHD,the proportion of children with single type was the highest,and that of children with three or more types were the lowest.Among children with CHD,the rate of delayed medical treatment was 76.19% (80/105).The median delay in medical treatment was 12 months,with an average of(18.78±4.77)months.Multifactor logistic regression analysis showed that heart murmur(level 2～3),less-educated(primary and secondary school)guardian,family per capita income<2 000 yuan,and frequent drinking of the guardian were independent risk factors for delayed medical treatment(P<0.05),and commercial settlement of medical expenses was independent protective factor(P<0.05).Risk scoring model divided the children into three groups:low risk(≤80 points),medium risk(>80 points and≤134 points)and high(>134 points)risk group.The evaluation of the model show that it was accurate,effective,safe,and reliable.Conclusion The highest prevalence is observed in Liping County.The proportion of children with secondary atrial septal defect and the proportion of children with single type are the highest.Delayed medical treat-ment is found in most of the children with CHD.Cardiac murmur,education background of the guardian,per capita family income,guardian alcohol consumption,and medical expense settlement method are all independent influencing factors for delayed medical treatment.

Objective:To translate the Glaucoma Symptom Scale (GSS) into Chinese, and to test its reliability and validity.Methods:Following the Brislin questionnaire translation principles, GSS was translated, back-translated and culturally adapted, and the Chinese version of GSS was formed. From January 2021 to June 2022, a total of 210 glaucoma patients in Ophthalmology Outpatient and Inpatient Department of Class Ⅲ Grade A hospitals in Hefei were enrolled as the research objects by the convenience sampling method. The items of the Chinese version of GSS were screened by correlation coefficient method, critical ratio method and Cronbach's α coefficient. The reliability of the Chinese version of GSS was tested using Cronbach's α coefficient, split-half reliability and test-retest reliability. The validity of the GSS was evaluated by content validity and construct validity. Receiver operating characteristic (ROC) curve was drawn to evaluate the predictive ability of the Chinese version of GSS, and to determine the sensitivity, specificity and the most appropriate critical value of GSS. Pearson correlation analysis was used to explore the correlation between the total score of GSS and the score of each item. A total of 210 questionnaires were distributed in this study, and 205 were effectively received, with an effective recovery rate of of 97.62% (205/210) .Results:A total of 2 common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 50.64%. With clinician's diagnosis as the gold standard, the area under the curve of the Chinese version of GSS was 0.916 (95% CI: 0.886-0.947, P<0.01). The optimal critical score of the scale was 73, and the sensitivity and specificity were 85.2% and 87.3%. The concordant Kappa value of the two diagnostic results was 0.749 ( P<0.01). The Cronbach's α coefficient, split-half reliability and test-retest reliability of the Chinese version of GSS were 0.812, 0.781 and 0.912, respectively. Conclusions:The Chinese version of the GSS has good reliability and validity, and is suitable for the screening of glaucoma patients in China.

Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

Objective:Small cell lung cancer (SCLC) is a highly malignant tumor with a high risk of brain metastasis (BMs). The purpose of this study was to evaluate the clinical factors affecting the occurrence of BMs in patients with stage IIB-IIIB SCLC who achieved complete remission (CR) after thoracic radio-chemotherapy.Methods:Clinical data of 191 patients with stage IIB-IIIB SCLC who achieved CR after thoracic radio-chemotherapy in Zhejiang Cancer Hospital from January 2009 to April 2016 were retrospectively analyzed. Common clinical factors related to the risk of BMs, including gender, age, thoracic radiotherapy dose, combined mode of radiotherapy and chemotherapy, pretreatment serum NSE and LDH, whether PCI was performed, TMN stage and PS score, were analyzed using log-rank method for univariate analysis, COX regression method for multivariate analysis and Kaplan-Meier method to plot the survival curve.Results:Univariate analysis showed that pretreatment LDH level≥240IU, pretreatment NSE ≥17 ng/ml and no PCI were positively correlated with the risk of BMs (all P＜0.05). Multivariate analysis showed that the risk of BMs was only positively correlated with pretreatment LDH≥240IU [HR: 1.90, 95%CI(1.07-3.37), P=0.029], and no PCI [HR:2.08, 95%CI(1.17-3.72), P=0.013]. Conclusion:Pretreatment serum LDH levels provide important value for predicting the risk of BMs in patients with stage IIB-IIIB SCLC who achieve CR after thoracic radio-chemotherapy.

Objective:To understand the molecular transmission characteristics of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome(AIDS) patients in the mountainous area of southwest Zhejiang Province(Lishui city).Methods:A total of 147 blood samples were collected from newly-diagnosed HIV-1 infected who received no antiviral therapy, and pol gene was amplified, followed by sequencing. MEGA6.0 software was used to construct phylogenetic tree and determine gene subtypes. HIVDB online was used to analyze drug resistance mutation, then the pairwise genetic distance(GD) was calculated and the opitimal threshold of GD was selected, finally the molecular transmission network was constructed by Cytoscape3.7.0 software. Chi-square or Fisher′s exact probability method was used for statistical analysis. Results:A total of 134 sequences were obtained successfully, and nine subtypes were detected. The dominant subtypes were CRF08_BC (34.33%, 46/134), CRF01_AE (29.85%, 40/134) and CRF07_BC (23.88%, 32/134). It also found that age, registered residence, education level and transmission route had significant differences in distribution of subtypes ( P<0.05). Nineteen drug resistance individuals were found, and the total drug resistance rate was 14.18% (19/134). The HIV-1 molecular transmission network was plotted based on 1.2% GD threshold. A total of 15 transmission clusters (cluster size ranging from 2 to 29) were found. The network access rate was 49.25% (66/134), mainly including male (75.76%, 50/66), heterosexual (81.82%, 54/66) and patientsrinfected with CRF08_ BC (50.00%, 33/66). A transmission cluster including two cases of female sex workers and seven cases of drug resistance was identified, in which the average age of the patients was 57.21 years old and the average degree value was 22.7, and the cases were mainly infected through heterosexual contact (96.55%, 28/29). The highest homology of the sequences in the cluster was in Yunnan. Conclusions:The HIV-1 subtypes were diverse in the mountainous area of southwest Zhejiang Province(Lishui city). Drug resistant transmission had reached a moderate epidemic level. There were molecular transmission clusters with the aggregation characteristics of elderly clients in specific regions. It was urgent to formulate and implement precise intervention strategies to curb the spread of HIV.

Objective:To evaluate the value of whole exome sequencing (WES) in prenatal clinical application.Methods:A total of 1 152 cases of congenital abnormal [including structural malformation, nuchal translucency (NT) thickening and intrauterine growth restriction] with traditional prenatal diagnosis [including G-band karyotype analysis and chromosome microarray analysis (CMA)] negative were analyzed. The congenital abnormal fetuses were divided into retrospective group and prospective group according to the time of WES detection, that is whether the pregnancy termination or not. According to the specific location of fetal malformation and their family history, the cohort was divided into subgroups. The clinical prognosis of all fetuses were followed up, and the effect of WES test results on pregnancy decision-making and clinical intervention were analyzed. According to the follow-up results, the data of fetuses with new phenotypes in the third trimester or after birth were re-analyzed.Results:Among 1 152 families who received WES, 5 families were excluded because of nonbiological parents. Among the remaining 1 147 families, 152 fetuses obtained positive diagnosis (13.3%,152/1 147), including 74 fetuses in the retrospective group (16.1%,74/460) and 78 fetuses in the prospective group (11.4%,78/687). In fetuses with negative CMA and G-band karyotype analysis results but new phenotypes in the third trimester or after birth, the positive rate by WES data re-analysis was 4.9% (8/163). A total of 34 (21.3%, 34/160) fetuses were directly affected by the corresponding positive molecular diagnosis. Among 68 cases of live births with diagnostic variation grade 4, 29 cases (42.7%, 29/68) received appropriate medical intervention through rapid review of WES results.Conclusions:WES could increase the detection rate of abnormal fetuses with negative G-banding karyotype analysis and CMA by 13.3%. Prenatal WES could guide pregnancy decision-making and early clinical intervention. It might be an effective strategy to pay attention to the special follow-up of the third trimester and postnatal fetus and to re-analyze the WES data.

OBJECTIVE: To investigate the application value of whole exome sequencing technology in fetuses with congenital structural abnormalities. METHODS: The chromosomal abnormalities of 1147 families were analyzed. According to the follow-up results, the data of fetuses with new phenotypes in late pregnancy or after birth were reanalyzed. Subgroups were divided according to the organs involved and whether single malformation or not. The gene regulatory network map was drawn by using string database and Cytoscape software. Fisher exact probability method was used to compare the difference of the diagnostic rate of pathogenic genes among the groups. RESULTS: A total of 160 fetal cases received positive molecular diagnosed, involving 178 variant sites of 125 pathogenic genes, including 8 cases (4.9%, 8/163) by data reanalysis, and the overall positive diagnosis rate was 13.9%. Diagnostic rate was highest in the group of skeletal malformation (31.5%, 39/124) and lowest in that with thoracic malformation (0, 0/32). The gene clusters of fetal edema and intrauterine growth restriction were independent, and were not associated with the major structural malformations. The probability of each parent carrying the same recessive gene variant was 0.03 (39/1146) and 0.08 (4/53) with positive family history. CONCLUSION For fetuses with congenital structural abnormalities that are negative for conventional genetic tests, 13.9% of phenotypic associated pathogenic/likely pathogenic genetic variants can be detected by whole exome sequencing technology. Its application value for prenatal diagnosis varies in fetus with different organs involved. Reanalysis of sequencing data for cases with new phenotypes in late pregnancy or after birth can further improve the molecular diagnosis rate. Further investigations are needed to explore the related genetic mechanisms.

OBJECTIVE: To assess the value of chromosomal microarray analysis (CMA) for fetal duodenal obstruction (DO). METHODS: Fifty-one fetuses with DO identified by prenatal ultrasound were divided into DO only group and DO with other anomaly group. CMA was carried out on amniotic fluid or umbilical blood samples, and the outcome of pregnancy of all cases were followed up. RESULTS: Eight fetuses (15.7%) were found with genomic abnormalities, which included 3 chromosomal aneuploidies and 5 copy number variations (CNVs), including one 17q12 microduplication syndrome, one 13q21.33q31.1 microdeletion, one 13q21.32q22.3 deletion, one 13q21.2q31.1 deletion and one 1q43q44 duplication. EDNRB from 13q and HNF1B from 17q12 are candidate genes for fetal DO. No significant difference was found in the detection rate of pathogenic CNVs between the DO only and DO with other anomaly groups (9.5% vs.11.1%, P> 0.05). There were 39 live borns, 1 stillbirth, and 11 artificial abortions (8 with abnormal CMA results). CONCLUSION There is a correlation between fetal DO and abnormal copy number of the genome, for which prenatal diagnosis is necessary. CMA not only can detect microdeletions/microduplications, but also identify pathogenic genes, which can facilitate prenatal diagnosis, genetic counseling and prognosis for the fetus.
