Objective:To investigate the influence of prenatal stressful life event (SLE) exposure on child emotional and behavioral problem at age 2-6 years and identify the most risk exposure period.Methods:A total of 2 524 mother-child pairs were selected from Shanghai Maternal-Child Pairs Cohort based on pregnant women form 2016 to 2018 in Shanghai. Prenatal SLE exposure was assessed by Life Events Scale for Pregnant Women Questionnaire during the first and third trimester of pregnancy. Child emotional and behavioral problem was evaluated by Strengths and Difficulties Questionnaire at age 2-6 years. Multivariate binary logistic regression model and generalized estimating equation were conducted to quantify the association between prenatal SLE exposure and child emotional and behavioral problem at age 2-6 years, and identify the pregnancy period with strongest adverse effect.Results:The 2 524 mother-child pairs were divided into 4 groups: group with consistent low exposure to SLE (61.8%), group with high exposure to SLE in the first trimester (13.2%), group with high exposure to SLE in the third trimester (13.2%) and group with consistent high exposure to SLE (11.8%). The detection rates of emotional problem, hyperactivity, peer interaction problem and total difficulty score in children aged 3-6 years were highest in the group with consistent high exposure to SLE. Generalized estimating equation analysis showed that after controlling the confounding factors, compared with the consistent low exposure group, the children in the group with high exposure to SLE in the first trimester had significant increased risk for conduct problem at age 2-6 years (a OR=1.41, 95% CI:1.07-1.87). The children in the group with consistent high exposure to SLE were at increased risk for emotional problem, peer interaction problem, and high total difficulty score with the a OR of 1.41 (95% CI: 1.09-1.83), 1.46 (95% CI: 1.15-1.86) and 1.51(95% CI: 1.17-1.93). Conclusion:These findings indicated that prenatal exposure to SLE have adverse effect on child emotional and behavioral problem at age 2-6 years, especially the exposure in the first trimester.

Purpose To investigate the clinical value of multi-center digital mammography radiomics nomogram model in predicting triple-negative breast cancer(TNBC).Materials and Methods The digital mammograms of 462 patients with pathologically confirmed breast cancer from November 2016 to March 2022 were retrospectively analyzed,including 243 cases from Yijishan Hospital of Wannan Medical College(institution 1),106 cases from Fuyang People's Hospital(institution 2)and 113 cases from Taihe People's Hospital(institution 3).According to the results of immunohistochemistry,a total of 349 breast cancer patients in institution 1 and institution 2 were randomly divided into the training group(244 cases,including 41 TNBC and 203 non-TNBC)and the validation group(105 cases,including 18 TNBC and 87 non-TNBC)according to the ratio of 7∶3,113 breast cancer patients(24 TNBC and 89 non-TNBC)from institution 3 were included in the external validation group.Comparing the mediolateral oblique and cranial cauda digital mammography images,the mammography imaging with larger lesion areas were selected,and the image segmentation and radiomics feature extraction were performed.The radiomics model was constructed by using Logistic regression.The clinicopathological parameters and radiomics scores were used to construct a nomogram.Receiver operating characteristic and decision curve analysis were used to evaluate the model performance.To compare The predictive performance between the models was compared.Results Finally,four radiomics features closely related to TNBC were selected to construct an radiomics model.The area under the curve,sensitivity and specificity of TNBC predicted by the radiomics model in training group,validation group and external test group were 0.868,90.24%and 72.91%,0.827,72.22%and 75.86%,0.837,70.83%and 78.65%,respectively.The area under the curve,sensitivity and specificity of TNBC predicted by the combined model in the training group,validation group and external test group were 0.903,80.49%and 86.70%,0.890,77.78%and 88.51%,0.870,62.50%and 85.39%,respectively.The combined model was better than the single image omics model in predicting TNBC,and the difference was statistically significant between the training group and the verification group(Z=2.061,2.064,both P<0.05),but not between the external test group(Z=1.223,P=0.221).In three group,decision curve analysis showed that the nomogram predicted a higher net benefit than the radiomics model for triple-negative breast cancer.Conclusion The radiomics model has high diagnostic efficiency in predicting TNBC,and the nomogram model combined with the radiomics score and histological grading can further improve the prediction efficiency.

This study was designed to evaluate the correlation between immune antibodies and pelvic inflammatory disease(PID)using retrospective analysis.Cases were selected from 171 patients who met the diagnosis of PID in Liuzhou People's Hospital of Guangxi Province from January 2022 to March 2023,and the PID patients were further divided into simple PID group(53 cases)and in PID combined with reproductive tract infection group(118 cases)according to the presence or absence of reproductive tract infections,while 83 cases of women who did not meet the specific diagnostic criteria of PID and did not have reproductive tract infections were selected as the control group during the same period.The positive rate of immune antibodies in the three groups were observed and compared to explore the relationship between immune antibodies and PID.Data showed that the positive rates of immune antibodies were significantly higher in the PID alone group and the PID combined with reproductive tract infection group than that in the control group.Furthermore,the positive rate of immune antibody TPOAb was significant difference in the PID combined with reproductive tract infection group and the PID alone group(P<0.05).In conclusion,TPOAb is closely associated with reproductive tract infections.

Objective: To evaluate the characteristics and related factors of physical activities both inside and outside the kindergarten among preschool children, so as to provide a reference for promoting targeted physical activities among different types of children in the future. Methods: From April 2016 to December 2022, 706 preschool children aged 3 to 6 years from the Shanghai parent child cohort followed up. Accelerometers were used to measure their physical activities during kindergarten hours, and a parent questionnaire was employed to assess their physical activities and screen time outside the kindergarten. Restrictive cubic spline analysis was used to examine the relationship between moderate to vigorous physical activities (MVPA) inside and outside the kindergarten. Cluster analysis was performed to identify physical activity patterns among children, and multinomial Logistic regression analysis was conducted to explore the influencing factors of these physical activity patterns. Results: On weekdays, preschooler accumulated an average of (40.83±15.71) minutes of MVPA inside the kindergarten and 30(15, 53) minutes outside daily. Restricted cubic spline analysis revealed an inverted U shaped relationship between MVPA inside and outside the kindergarten. Cluster analysis identified four groups: low daily MVPA but active inside (196, 27.8%), moderate daily MVPA but high screen time outside (97, 13.7%), adequate daily MVPA and relatively active outside (96, 13.6%), and low daily MVPA and relatively inactive both inside and outside (317, 44.9%). Compared to the reference group of adequate daily MVPA and relatively active outside, children with screen time exceeding 60 minutes at 2 years old were more likely to belong to the group with adequate daily MVPA but more screen time outside ( OR =3.84, 95% CI =1.16-12.74, P <0.05). Boys had a lower likelihood of being in the group with low daily MVPA and relatively inactive both inside and outside ( OR =0.33, 95% CI =0.16-0.70, P <0.05). Children from neighborhoods with insufficient sport facilities were more likely to be in the low daily MVPA and relatively inactive group ( OR =2.20, 95% CI = 1.05 -4.63, P <0.05). Conclusions Behavior patterns of physical activity and screen time for both inside and outside the kindergarten vary greatly among different children. Screen time at the age of 2 and the sports facilities around the commuinty are key factors influencing the physical activity pattern. It is recommended to implement personalized intervention plans in collaboration with schools and families for different types of children.

Objective: To investigate the distribution of various types of screen time and examine the association of screen time with psychological and behavioral development problems in children aged 3-6 years, so as to provide scientific basis for children s screen use and mental health promotion. Methods: A total of 3 875 mother child dyads who completed the follow up in Shanghai Maternal-Child Pairs Cohort were included. The daily usage time of children s tablet, mobile phone, TV, projectors, and other types of screens were obtained in questionnaire survey. Children s psychological and behavioral development problems were evaluated by Age-Stage Questionnaire, Third Edition (ASQ-3) and Strengths and Difficulties Questionnaire (Parent version) (SDQ). The Chi-square test, Mann Whitney U and Kruskal Wallis rank sum test were used to compare the detection rate of psychological and behavioral development problems and screen time in children with different characteristics. Multivariate binary Logistic regression was used to analyze the association of screen time with psychological and behavioral development problems. Results: There were 49.91% of children having screen time more than 1 h/d. Children s TV, tablet and mobile phone screen time were 0.39(0.25, 0.96 ), 0.25(0,0.61) and 0.18(0,0.25) h/d. The detection rates of suspected developmental delay in fine motor, problem solving and personal-social domains and pro social behavior deficiency and externalizing behaviors in boys (8.54%, 6.77%, 5.46%, 30.07 %, 27.39%) were higher than that in girls (4.64%, 4.85%, 2.48%, 22.10%, 22.36%) ( χ 2=23.76, 6.49, 22.37, 31.81, 13.06, P <0.05). There were statistically significant differences in the detection rates of suspected developmental delay in communication, fine motor and problem solving, as well as internalizing behavior and externalizing behavior of children with different parents educational levels ( χ 2=14.37, 15.18, 21.10, 11.66, 9.27; 16.34, 26.75, 32.89, 16.97, 6.37, P <0.05). There were significant differences in the detection rates of suspected developmental delay in problem solving, prosocial behavior deficiency, internalizing behavior and externalizing behavior of children whose mothers had anxiety/depression symptoms during pregnancy ( χ 2= 5.61 , 9.05, 21.90, 7.17; 8.75, 6.06, 12.76 , 5.55, P <0.05). The average total screen time of boys was longer than that of girls (1.07, 1.00 h/d, Z=-2.08, P =0.04). Compared with children with other educational levels of their parents, the total screen time, mobile phone and TV screen time of children whose parents had college education or above were short (father: H =42.01, 44.49 , 21.24, mother: H =42.31, 39.21 , 26.47, P <0.01). Among all types of screen time, mobile phone screen time had the most impact on psychological and behavioral development. More mobile phone screen time increased the risk of suspected developmental delay and abnormal emotional behavior ( P < 0.05). Screen time of tablet, mobile phone and TV were positively correlated with externalizing behavior ( OR=1.36, 1.57, 1.27 , P <0.05). Conclusions Screen time is related to children s psychological and behavioral development problems and mobile phones affect the most. Parents should limit their children s screen time to avoid excessive screen time affecting their psychological and behavioral development.

The isolated type of orofacial cleft, termed non-syndromic cleft lip with or without cleft palate (NSCL/P), is the second most common birth defect in China, with Asians having the highest incidence in the world. NSCL/P involves multiple genes and complex interactions between genetic and environmental factors, imposing difficulty for the genetic assessment of the unborn fetus carrying multiple NSCL/P-susceptible variants. Although genome-wide association studies (GWAS) have uncovered dozens of single nucleotide polymorphism (SNP) loci in different ethnic populations, the genetic diagnostic effectiveness of these SNPs requires further experimental validation in Chinese populations before a diagnostic panel or a predictive model covering multiple SNPs can be built. In this study, we collected blood samples from control and NSCL/P infants in Han and Uyghur Chinese populations to validate the diagnostic effectiveness of 43 candidate SNPs previously detected using GWAS. We then built predictive models with the validated SNPs using different machine learning algorithms and evaluated their prediction performance. Our results showed that logistic regression had the best performance for risk assessment according to the area under curve. Notably, defective variants in MTHFR and RBP4, two genes involved in folic acid and vitamin A biosynthesis, were found to have high contributions to NSCL/P incidence based on feature importance evaluation with logistic regression. This is consistent with the notion that folic acid and vitamin A are both essential nutritional supplements for pregnant women to reduce the risk of conceiving an NSCL/P baby. Moreover, we observed a lower predictive power in Uyghur than in Han cases, likely due to differences in genetic background between these two ethnic populations. Thus, our study highlights the urgency to generate the HapMap for Uyghur population and perform resequencing-based screening of Uyghur-specific NSCL/P markers.

OBJECTIVETo explore the clinical and genetic characteristics of patients with dentatorubro-pallidoluysian atrophy (DRPLA).

METHODSDNA analysis for DRPLA gene was performed in two patients. Clinical features and genetic testing of Chinese DRPLA patients reported in the literature were reviewed in terms of initial symptoms, CAG repeat and age of onset.

RESULTSBoth families were confirmed by genetic analysis. In family 1, the number of CAG repeat in the proband, his brother and his mother was determined respectively as 8/65, 8/53 and 8/18. In family 2, the number of CAG repeat was respectively 13/63, 13/18, 18/52 and 13/13 in the proband, his brother, his father and his mother. The size of the expanded CAG repeats has inversely correlated with the age at onset (P<0.05, r=- 0.555). The age at onset of epilepsy was 10 and that for the onset of ataxia is forty years in initial symptom.

CONCLUSIONThe clinical characteristics of DRPLA include epilepsy, ataxia and cognitive impairment. The initial symptoms are epilepsy in adolescence and ataxia in adults. The size of expanded CAG repeats inversely correlates with the age at onset. The initial symptoms are different with different age of onset. It is difficult to diagnose DRPLA at an early stage.

Objective Based on the Traditional Chinese Medicine Inheritance Support System (TCMISS) (V2.0), to analyze the point-selection rules in acupuncture-moxibustion prescriptions for gastroptosis indexed by China National Knowledge Infrastructure (CNKI), Wanfang and Vip databases, and to obtain novel prescriptions, for providing clinical references. Method Acupuncture-moxibustion prescriptions for gastroptosis indexed by CNKI, Wanfang and Vip databases were collected and filtered, and then input into the TCMISS. The prescriptions were analyzed by using data mining method. Result The frequency and core combination of the commonly-used acupoints were determined out of the 76 eligible prescriptions for gastroptosis, and 3 novel prescriptions were obtained. Conclusion The TCMISS is an important tool in mining and analyzing the point-selection rules in acupuncture-moxibustion treatment, and the new acupoint prescriptions generated by this system provide references to the treatment of gastroptosis.

Background and purpose:The recurrence and metastasis of gastric cancer seriously affect survival in patients.SOX gene as a regulatory factor of the classical Wnt pathway, may play an important role in the process. This study was to explore the expression of stem cell marker SOX-2 and β-catenin in gastric cancer and to analyze the relationship with recurrence and metastasis after operation.Methods:Immunohistochemistry was used to detect the expression of SOX-2 and β-catenin in 71 tumor samples from 71 cases after surgery for gastric cancer. The correlation between SOX-2 and β-catenin expression and the clinicopathological characteristics of gastric cancer and disease-free survival was analyzed.Results:The SOX-2 protein expression was associated with metastasis, lymph node inifltration or differentiation (P=0.011,P=0.036,P=0.034) in the 71 gastric cancer, but not with gender, age or T stage. β-catenin expression was correlated with metastasis, lymph node invasion or T stage (P=0.025,P=0.014,P=0.026), but was not related to differentiation, gender or age. The survival analysis showed that SOX-2 and β-catenin expression was closely associated with prognosis of patients, and metastatic rate in positive expression was higher than that in negative expression.Conclusion:The expression of SOX-2 and β-catenin is associated with the development, recurrence, metastasis of gastric cancer and may be used as a useful prognostic parameter to predict overall survival.

Objective To establish the insulin resistant HepG2(HepG2/IR)cells model,and investigate the relationship of insu-lin resistance and reduced susceptibility to chemotherapy in hepatoma cells and its mechanism.Methods HepG2 cells were cultured in medium containing 0.5μmol/L insulin for different hours to induce insulin resistance.Glucose consumption of HepG2/IR cells were measured by Hitachi 7600 automatic biochemical analyzer.The cis-dichlorodiamineplatinum(DDP)sensitivity of the HepG2 and HepG2/IR cells were determined by MTT assay,the Annexin Ⅴ/PI assay was adopted to measure the apoptosis rate.In addi-tion,real-time PCR,flow cytometry (FCM)and Western-Blot were employed to detect the mRNA and protein levels of insulin re-ceptor(InsR)and endoplasmic reticulum chaperonin 78(GRP78).Results The glucose consumption decreased and expression of In-sR was down-regulated in HepG2/IR cells.The HepG2/IR cells had reduced sensitivity to DDP (P<0.05 ).The IC50 s of the HepG2/IR cells treated by DDP for 48 h and 72 h were 158.8% and 165.9% of HepG2 cells respectively,while the apoptosis rate was 50.29% lower.The mRNA and protein level of GRP78 in HepG2/IR cells were 2.12 and 2.27 times of that in HepG2 cells. Conclusion The stable HepG2/IR cells showed stronger resistance to DDP were established from HepG2 cell induced with insulin, and its mechanism may be related to the increased expression of GRP78.
