Objective:To investigate electrocardiogram (ECG) characteristics and related factors of gestational diabetes mellitus (GDM) complicated by depressive disorder.Methods:The clinical data of 243 patients with GDM who received treatment at Peking University Third Hospital from September 2021 to December 2022 were retrospectively analyzed. According to the scoring results of the Self-rating Depression Scale (SDS), these patients were divided into an observation group (GDM + depressive disorder, n = 51) and a control group (GDM alone, n = 192). The χ2 test was used to analyze the relationship between GDM complicated by depressive disorder and ECG diagnosis results. Additionally, the t-test was used to compare ECG indicators between the two groups. Results:Compared with the control group, patients in the observation group had a higher incidence of abnormal ECG indicators, including bradycardia ( χ2 = 4.68, P = 0.030), premature contraction ( χ2 = 10.78, P = 0.001), and atrioventricular block ( χ2 = 15.04, P < 0.001). However, there were no significant differences in the incidences of tachycardia, bundle branch block, or ST-T changes between the two groups (all P > 0.05). Compared with the control group, the observation group exhibited significantly increased heart rate [(73.43 ± 8.24) beats/min vs. (67.22 ± 5.08) beats/min], maximum QT interval [(419.09 ± 36.00) ms vs. (351.95 ± 32.07) ms], minimum QT interval [(363.31 ± 30.78) ms vs. (316.52 ± 29.10) ms], and QT dispersion [(55.78 ± 17.87) ms vs. (35.42 ± 13.18) ms, t = -5.13, -12.95, -10.08, -7.60, all P < 0.001]. Conclusion:Among patients with gestational diabetes mellitus, those with depressive disorder have an increased risk of exhibiting abnormal electrocardiogram patterns compared with those without depressive disorder.

Objective:To evaluate the prognostic effects of two comprehensive geriatric assessment (CGA) methods in elderly patients with acute myeloid leukemia (AML).Methods:Ninety-seven patients with newly diagnosed AML at Beijing Hospital from August 2008 to December 2019 were included (≥60 years old). All patients were evaluated by two methods of CGA. One was IACA index proposed by Beijing Hospital, including instrumental activities of daily living (IADL), age, Charlson comorbidity index (CCI), albumin; the other was proposed by Italian FIL study group (FIL-CGA), including activities of daily living (ADL), IADL, age, and modified cumulative illness rating score for geriatrics (MCIRS-G).Results:Among 97 patients, 54 patients received standard chemotherapy, 16 with decitabine, 2 with targeted therapy and 25 with the best supportive therapy. The overall response rate (ORR) in 72 treated patients were 67.7%, 33.3% and 0 respectively in fit, unfit and frail groups according to IACA index ( P=0.001). Based on FIL-CGA, the ORRs of fit, unfit and frail groups were 52.5%, 41.7% and 35.0% respectively ( P=0.418). The 1-year OS rates of fit, unfit and frail groups regarding IACA method were 78.7%, 27.7% and 0 respectively ( P<0.01). The 1-year OS rates of fit, unfit and frail groups regarding FIL-CGA method were 67.8%, 28.2% and 13.9% respectively ( P<0.01), while no significant difference was seen between unfit group and frail group ( P=0.111). The early death rates of fit, unfit and frail groups by IACA were 0, 6.0% and 28.6% respectively ( P=0.006), while those by FIL-CGA were 2.3%, 5.9%, 13.9% respectively ( P=0.123). Conclusion:Compared with FIL-CGA method, IACA predicts more effectively the treatment response, survival and early mortality in elderly patients with AML.

Objective To identify the dietary patterns among preschoolers in Ma'anshan,and to investigate its association with the education levels of the parents.Methods A total of 16 439 children aged 3-6 were recruited from 91 kindergartens in Ma'anshan city to participate in the study.Food frequency and socio-demographic information were collected through questionnaire survey.Dietary data was collected using a food frequency questionnaire (FFQ),and principal-components analysis was used to derive the dietary patterns.Ordinal multinomial logistic regression was employed to explore the association between the education level of parents and the dietary patterns.Results Five dietary patterns-"processed","beverage","snack","protein" and "vegetarian" were identified.Data showed that the total variance was 48.02％ and the cumulative proportion of processed reached 24.78％.Low educational level of the father was positively associated with both "beverage"(OR=1.36,95％CI:1.15-1.63) and "snack" dietary pattern (OR=1.21,95％CI:1.01-1.43).Low educational level of mother was positively associated with the "processed" (OR =1.31,95％CI:1.09-1.57) and "beverage"dietary pattern (OR=1.48,95％CI:1.23-1.77),and showed a negative correlation with "protein" (OR=0.62,95％ CI:0.52-0.74) and "vegetarian" dietary pattern (OR=0.72,95％ CI:0.60-0.86).Conclusion Findings from this study showed that preschoolers in Ma'anshan tend to choose unhealthy dietary pattern.Dietary pattern was directly influenced by the parents,and especially the education level of the mothers.

Objective: To understand the epidemiological characteristics and relevant factors on the comorbidity of hyperactivity behavior and allergic disease among preschool children in urban areas of Ma'anshan city. Methods: During April 2014 to April 2015, 91 kindergartens over 3 years old were investigated. In the investigation, 16 439 questionnaires were distributed to parents, and 15 291 valid questionnaires were collected. Conners abbreviated symptom questionnaire (brief symptom questionnaire) was filled out by parents to assess the children's hyperactive behaviors. Information of allergic disease history was reported by parents, including allergic dermatitis/eczema, food/drug allergy, allergic rhinitis and asthma. Multivariate unconditional logistic regression was used to analyze the relevant factors of comorbidity of hyperactivity behavior and allergy diseases. Results: The average age of the 15 291 children were (4.5±1.0) years old, among which 53.7% (8 218/15 291) were boys. The prevalence of hyperactive behaviors was 8.6%(1 317/15 291), and the comorbidity rate of hyperactivity and allergic deseases was 1.7% (258/15 291). After confounding factors including gender, age, delivery mode, father's age and pregnancy complications adjusted, poor sleep quality (OR=4.45, 95%CI: 2.85-6.94), long duration of watching TV at weekend (OR=1.39, 95%CI: 1.00-1.94) and poor eating behavior (OR=1.78, 95%CI: 1.07-2.98) were relevant factors of the comorbidity of hyperactivity and allergic diseases. Conclusion The prevalence of comorbidity of hyperactivity behavior and allergic disease among preschool children in urban areas of Ma'anshan city was not high. Poor night sleep quality, long duration of watching TV and frequently picky eating were relevant factors of the comorbidity of hyperactive behaviors and allergic diseases.

OBJECTIVETo examine the effect of parents' occupational and life exposure during six months before pregnancy on executive function of preschool children.

METHODSPregnant women involved in the study came from the Ma'anshan Birth Cohort Study,a part of the China-Anhui Birth Cohort Study. Between October 2008 and October 2010, pregnant women who accepted pregnancy care in four municipal medical and health institutions in Ma'anshan city were recruited as study objects. A total of 5,084 pregnant women and 4,669 singleton live births entered in this cohort. Between April 2014 and April 2015, a total of 3,803 pre-school children were followed up. Finally, except 32 preschool children did not have EF evaluation result, there were 3,771 children included in this study. By using self-designed " Maternal health handbook", we researched parents' general demographic characteristics, and life and occupational exposure during six months before pregnancy. To research preschool children's executive function, we used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Univariate and multivariate statistical method was used to analyze the association of parents' life and occupational exposure during six months before pregnancy and preschool children's EF.

RESULTS3,771 preschool children's detected rate of inhibitory self-control index (ISCI), flexibility index (FI), emergent metacognition index (EMI) and global executive composite (GEC) dysplasia were 4.8% (182), 2.3% (88), 16.5% (623) and 8.6% (324) respectively. During six months before pregnancy, children whose parents were lived in a noise environment (OR=1.86, 95% CI: 1.36-2.54), whose maternal were exposed to pesticides were the risk of ISCI dysplasia(OR=3.60, 95% CI: 1.45-8.95). During six months before pregnancy, children whose maternal were exposed to pesticides (OR=6.72, 95% CI: 2.50-18.07) and whose father were exposed to occupational lead (OR=2.10, 95% CI: 1.25-3.54) were the risk of FI dysplasia. During six months before pregnancy, children whose parents were lived in a noise environment (OR=1.42, 95%CI: 1.18-1.71) and whose father were exposed to occupational lead (OR=1.30, 95%CI: 1.02-1.65) were the risk of EMI dysplasia. During six months before pregnancy, children whose parents were lived in a noise environment (OR=1.58, 95% CI: 1.24-2.01) and whose maternal were exposed to pesticides (OR=2.39, 95% CI: 1.02-5.58) were the risk of GEC dysplasia.

CONCLUSIONThe development of executive function is worse among preschool children whose parents live in noise environment, mother exposed to pesticides, and father exposed to occupational lead during six months before pregnancy.

OBJECTIVETo investigate the related influencing factors of preschool children's emotional and behavioral problems in early life and explore the associations between the symptoms of depression or anxiety during pregnancy and emotional and behavioral problems in preschool children.

METHODSBased on the Ma'anshan Birth Cohort Study of the China-Anhui Birth Cohort Study (C-ABCS), women were recruited at their first clinical visit between October 2008 and October 2010 in four municipal medical and health institutions of Ma'anshan City, a total of 5 084 pregnant women and 4 669 singletons live births were included in the birth cohort. Women completed measures of depressive (Self-Rating Anxiety scale) and anxious (Center for Epidemiologic Studies Depression) symptoms in pregnancy. By the age of 3-6 follow-up, 3 653 children were followed with completed information between April 2014 and April 2015, strengths and difficulties questionnaires were used to assessed offspring emotional and behavioral problems. Logistics regression was used to investigate the relationship between the symptoms of depression or anxiety during pregnancy and emotional and behavioral problems in preschool children.

RESULTSThe detected rates of emotional symptoms, conduct problems, hyperactivity and peer problems in preschool children were 6.3% (229/3 653), 7.5% (274/3 653), 7.6% (278/3 653) and 2.8% (103/3 653), while 7.6% (277/3 653) for total difficulties, 10.9%(398/3 653) for prosocial behavior and 27.4%(981/3 557) for impact respectively. Prevalence of anxiety and depression in the first trimester was 2.7%(100/3 653) and 4.7%(171/3 653) respectively, and in the second trimester was 2.0%(66/3 375) and 3.6%(122/3 375) respectively. After we controlled the confoundings of gestation age, place of residence, family income, maternal education, paternal education, premature birth and folic acid supplement before pregnancy, multinomial logistic regression analysis showed that the risk of children's emotional symptoms in maternal anxiety in both first-trimester and second-trimester group was higher than the group of no depression and anxiety symptoms, and OR(95%CI) was 5.90(2.00-17.48). Compared with whose mother no depression in both first-trimester and second-trimester, the risk of children's emotional symptoms in maternal depression in both first-trimester and second-trimester group was higher, and OR(95% CI) was 3.07 (1.30-7.28). And the risk of children's total difficulties of maternal anxiety in second-trimester was 2.27 (95%CI: 1.10-4.71) times of no anxiety in second-trimester. While the risk of children's total difficulties of maternal depression in second-trimester was 2.20 (95%CI: 1.24-3.93) times of no depression in second-trimester. Maternal emotional symptoms were not significant associations with conduct problems, hyperactivity, peer problems and prosocial behaviors (P> 0.05).

CONCLUSIONThere was a negative impact of maternal anxiety and depression symptoms during pregnancy on emotional and behavioral problems in preschool children. These findings highlight the need for additional clinical and research attention to both maternal depression and anxiety in pregnancy, which may be helpful to reduce the incidence of children's emotional and behavioral problems and act as an important measure in prevention.

OBJECTIVETo examine the effect of maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) with childhood overweight and adiposity, and to explore possible early life risk factors for obesity in preschool children.

METHODSBasic information of pregnant women and gestation period came from the Ma'anshan Birth Cohort Study, a part of the China-Anhui Birth Cohort Study (C-ABCS). Pregnant women in routine health care from four municipal medical and health institutions were enrolled voluntarily during October 2008 and October 2010 in Ma'anshan City. A total of 5 084 pregnant women and 4 669 singleton live births were included in this study. Between April 2014 and April 2015, 3 797 children were followed up. Children whose BMI were >85th percentiles for age and genders of World Health Organization (WHO) reference were considered as overweight, and >95th percentiles for age and genders cut-off values were considered as obesity (pathological and secondary causes of obesity were excluded). Gestational weight gain was defined according to the Institute of Medicine (IOM) guidelines. Univariate and binary regression model analysis was used to examine the effect of pre-pregnancy BMI and GWG with childhood overweight and adiposity.

RESULTSOf the 3 797 pregnant women, the prevalence of underweight, normal weight, overweight and obesity were respectively 22.6% (n=858), 70.3% (n=2 671), 6.2% (n=234) and 0.9% (n=34). There were 3 563 pregnant women who were obtained gestational weight gain data, the prevalence of inadequate GWG, appropriate GWG, excessive GWG were respectively 12.4% (n=443), 25.9% (n=922) and 61.7% (n=2 198). The prevalence of overweight and obesity were 11.5% (n=437) and 10.8% (n= 411) in preschool children, respectively. After adjusting confounding factors including age at delivery, genders of children, children age, birth weight, breastfeeding and household economic status, binary logistic regression analysis showed that pre-pregnancy overweight and obesity(OR=2.01, 95% CI: 1.53-2.65), excessive GWG(OR=1.65, 95% CI: 1.35-2.03) were risk factors for overweight and obesity, and pre-pregnancy underweight was protective factor for childhood overweight and obesity (OR=0.49, 95% CI: 0.39-0.62). Joint associations of pre-pregnancy BMI and inappropriate GWG were also noticed in the study: compared to only pre-pregnancy higher BMI or excessive GWG or indequate GWG, combination of high pre-pregnancy BMI and excessive GWG or high pre-pregnancy BMI and inadequate GWG, adverse effects on childhood overweight and obesity were much higher,OR (95%CI) values were 2.90(1.97-4.28), 3.17(1.44-6.97) respectively.

CONCLUSIONBoth high pre-pregnancy BMI and inappropriate GWG are associated with greater offspring BMI. Pregnant women should achieve appropriate weight gain and help prevent obesity in their children.

OBJECTIVETo analyze the associations between pregnancy-related anxiety and the prevalence of subthreshold autism trait (SAT) in preschool children.

METHODSBaseline data came from the Ma'anshan Birth Cohort Study, a part of the China-Anhui Birth Cohort Study (C-ABCS). All the participants were enrolled among pregnant women who received prenatal health care in 4 municipal medical centers during Oct. 2008 to Oct. 2010. A total of 5 084 pregnant women were recruited at the beginning and 4 669 singleton live births were included until childbirth. The situation about pregnancy-specific anxiety during trimester and third trimester of women were evaluated by Pregnancy-specific Anxiety Questionnaire (PAQ). Between April 2014 and April 2015, the cohort was followed up again, and the Clancy Autism Behavior Scale (CABRS) filled out by parents was used for telling the SAT children from the healthy children among 3 663 preschool children. Univariate and binary regression model was used to estimate associations between the pregnancy-related anxiety during trimester and third trimester and the subthreshold autism trait in children.

RESULTSDuring the pregnancy, the detected rates of women with pregnancy-specific anxiety in trimester and the third trimester were 25.5%(935/3 663), 13.9%(501/3 592) respectively, and the detected rate of maternal pregnancy-specific anxiety in both periods was 7.7%(278/3 592). There were 290 positive children with SAT and the detection rate was 7.9%. After controlling possible confounding factors including children's genders, place of residence, supplement folic acid during pregnancy, preterm birth, exposure to second-hand smoke during pregnancy, the father (mother) cultural levels, the father (mother) nature of work and family income, the results of multinomial logistic regression analysis showed that maternal pregnancy-specific anxiety in trimester was the risk factor for SAT in preschool children (OR=1.51, 95% CI: 1.11-2.04), and there was no association between maternal pregnancy-specific anxiety in the third trimester and SAT in preschool children (OR=1.36, 95% CI: 0.82-2.22). Compared with the single function of maternal pregnancy-specific anxiety in trimester or the third trimester for SAT in preschool children, maternal pregnancy-specific anxiety in both periods presented a joint action that increasing the risk for SAT (OR=2.02, 95% CI: 1.36-2.98).

CONCLUSIONMaternal pregnancy-related anxiety was a risk factor for subthreshold autism trait in preschooler children. Pregnant women should try to keep a good mental state to create a good environment for fetal growth.

OBJECTIVETo evaluate relevant prognostic factors of unrelated single unit umbilical cord blood hematopoietic stem cell transplantation (sUCBT), and to explore the correlation between cryopreservation time of cord blood and cell viability and outcome of sUCBT.

METHODSRetrospective analysis of 137 patients undergoing sUCBT with cord blood provided by Shanghai Cord Blood Bank from Mar. 15, 2007 to Dec. 26, 2013 were performed in this study. The mean cryopreservation time of 137 units cord blood was 698(96-1968) days, with mean cell viability of 87.4% after thawing.

RESULTSNo statistical difference on cell viability, hematopoietic reconstitution, graft failure, acute graft versus host disease (GVHD) and overall survival (OS) was found between patients transfused with cord blood preserved below and above 2 years. The 5-year OS of patients transfused with cord blood preserved below and above 2 years were 55.6% and 67.9%, respectively (P=0.124). OS of the UCBT at 2011 and before, and after 2011 was 48.7% and 79.6%, respectively (P=0.001). Age above 16-year-old (RR=2.830, P=0.027) and UCBT at 2011 and before (RR=0.203, P<0.001) were two risk factors of treatment related mortality.

CONCLUSIONOutcome of sUCBT in China had significant improvement in recent 2 years. Cryopreservation time of cord blood had no statistical correlation to cell viability after thawing and clinical outcome.

OBJECTIVETo investigate the impact of cryopreservation duration of umbilical cord blood (UCB) on quality of hematopoietic stem cell and outcome of clinical transplantation.

METHODS605 units of UCB which had been used in clinical transplantation were previously cryopreserved for 820 (88-2651) days in average. UCB was detected for total nucleated cell count, CD34+ cells count, cell recovery rate, cell viability and CFU-GM after thawing.

RESULTSNo statistical correlation was found between cryopreservation duration and cell recovery rate, cell viability. CFU-GM decreased along with the extension of cryopreservation duration (P=0.011), ranging between 109.6 and 105.7/1 × 10⁵. There was no significant difference on hematopoietic reconstitution time, graft failure, acute GVHD and overall survival among groups with different cryopreservation duration.

CONCLUSIONCryopreservation duration has no significant effect on cell recovery rate, cell viability and clinical transplantation outcome. Extension of cryopreservation duration may reduce CFU-GM of stem cells with fluctaion still in normal range. UCB could maintain cell viability and function to achieve satisfactory clinical transplantation outcome even when thawed after 3 to 7 years' cryopreservation.
