Objective To analyze the expression of N-MYC and N-MYC downstream regulated gene-1(NDRG1)in gastric cancer tissues,and to assess their effects on biological characteristics of gastric cancer cells.Methods Paired of gastric cancer tissues and adjacent normal tissues resected from 82 cases of patholog-ically confirmed gastric cancer who underwent surgical treatment in the hospital from January 2021 to May 2023 were collected.Gastric cancer tissues and adjacent normal tissues of 82 patients who were surgically re-sected and pathologically diagnosed with gastric cancer in the hospital from January 2021 to May 2023 were collected.Real-time quantitative PCR(qPCR)was used to detect the relative mRNA expression levels of N-MYC and NDRG1,and clinical data of the patients were collected.The correlation between the mRNA expres-sion of N-MYC and NDRG1 and clinicopathological features of the patients was discussed.NCI-N87 cells in logarithmic growth phase were selected and cultured in vitro.N-MYC interference plasmid(si-N-MYC)and its negative control(si-NC)was transfected into NCI-N87 cells,respectively,which were recorded as si-NC group and si-N-MYC group.Moreover,si-N-MYC was co-transfected into NCI-N87 cells with anti-NC and an-ti-NDRG1,respectively,and denoted as si-N-MYC+anti-NC group and si-N-MYC+anti-NDRG1 group.CCK-8 assay was used to detect cell proliferation activity,Transwell assay was used to detect cell invasion ability,and Western blotting assay was used to detect N-MYC and NDRG1 protein expression in cells.Results The relative expression of N-MYC mRNA in gastric cancer tissues was higher than that in paracancer tissues(P＜0.05),and the relative expression of NDRG1 mRNA was lower than that in paracancer tissues(P＜0.05).There were significant differences in the expression of N-MYC and NDRG1 mRNA in patients with different TNM stages,lymph node metastasis and distant metastasis(P＜0.05).Compared with the si-NC group,the cell proliferation and invasion ability of the si-N-MYC group were decreased(P＜0.05),and the expression of NDRG1 protein was down-regulated(P＜0.05).Compared with si-N-MYC+anti-NC group,cell proliferation and invasion ability of si-N-MYC+anti-NDRG1 group were increased(P＜0.05).N-MYC could target and regulate NDRG1,and knocking down NDRG1 could reverse the biological effects of N-MYC on gastric cells.Conclusion In gastric cancer tissue,N-MYC mRNA expression is upregulated and NDRG1 mRNA expression is downregulated,both of which play important roles in the regulation of malignant biological behaviors such as proliferation and invasion of gastric cancer cells.

Objective:To investigate the association between gestational blood pressure and neurodevelopment in 2-year-old children.Methods:Based on the"Wuhan Healthy Baby Birth Cohort", 3 754 mother-infant pairs were enrolled in this study. Based on multiple blood pressure measurements during pregnancy, the mean, cumulative, and variability of blood pressure throughout the entire pregnancy and each trimester were calculated. Blood pressure variability was evaluated using standard deviation (SD), coefficient of variability (CV), and variability independent of mean (VIM). Follow-up testing of neurodevelopment in infants and young children at the age of two was conducted to obtain the Mental Development Index (MDI) and the Psychomotor Development Index (PDI). The multivariate linear regression and generalized estimation equation were used to analyze the association between gestational blood pressure data and neurodevelopmental index.Results:The age of 3 754 pregnant women was (29.1±3.6) years, with a pre-pregnancy BMI of (20.9±2.7) kg/m2 and a gestational age of (39.3±1.2) weeks. The birth weight of 3 754 children was (3 330.9±397.7) grams, and the birth length was (50.3±1.6) centimeters. The results of the multivariate linear regression analysis showed that after adjusting for relevant confounding factors, the mean blood pressure, cumulative blood pressure, standard deviation of blood pressure, coefficient of variation of blood pressure, independent blood pressure variability of systolic blood pressure, diastolic blood pressure, and pulse pressure throughout pregnancy were negatively associated with the MDI and PDI scores of 2-year-old children. The analysis results of the generalized estimation equation showed that after adjusting for relevant confounding factors, the average systolic blood pressure in the first, second, and third trimesters was negatively associated with MDI/PDI. The negative association between cumulative blood pressure and MDI/PDI was only found in the first trimester. The negative association between blood pressure variation during pregnancy and MDI/PDI was mainly concentrated in the second and third trimesters.Conclusion:There is a negative association between gestational blood pressure and the neurodevelopmental index of 2-year-old children.

Background::Compared with human leukocyte antigen (HLA)-matched sibling donor (MSD) transplantation, it remains unclear whether haploidentical donor (HID) transplantation has a superior graft-versus-leukemia (GVL) effect for Philadelphia-negative (Ph-) high-risk B-cell acute lymphoblastic leukemia (B-ALL). This study aimed to compare the GVL effect between HID and MSD transplantation for Ph- high-risk B-ALL.Methods::This study population came from two prospective multicenter trials (NCT01883180, NCT02673008). Immunosuppressant withdrawal and prophylactic or pre-emptive donor lymphocyte infusion (DLI) were administered in patients without active graft-versus-host disease (GVHD) to prevent relapse. All patients with measurable residual disease (MRD) positivity posttransplantation (post-MRD+) or non-remission (NR) pre-transplantation received prophylactic/pre-emptive interventions. The primary endpoint was the incidence of post-MRD+.Results::A total of 335 patients with Ph- high-risk B-ALL were enrolled, including 145 and 190, respectively, in the HID and MSD groups. The 3-year cumulative incidence of post-MRD+ was 27.2% (95% confidence interval [CI]: 20.2%-34.7%) and 42.6% (35.5%-49.6%) in the HID and MSD groups (P = 0.003), respectively. A total of 156 patients received DLI, including 60 (41.4%) and 96 (50.5%), respectively, in the HID and MSD groups ( P= 0.096). The 3-year cumulative incidence of relapse was 18.6% (95% CI: 12.7%-25.4%) and 25.9% (19.9%-32.3%; P = 0.116) in the two groups, respectively. The 3-year overall survival (OS) was 67.4% (95% CI: 59.1%-74.4%) and 61.6% (54.2%-68.1%; P = 0.382), leukemia-free survival (LFS) was 63.4% (95% CI: 55.0%-70.7%) and 58.2% (50.8%-64.9%; P= 0.429), and GVHD-free/relapse-free survival (GRFS) was 51.7% (95% CI: 43.3%-59.5%) and 37.8% (30.9%-44.6%; P= 0.041), respectively, in the HID and MSD groups. Conclusion::HID transplantation has a lower incidence of post-MRD+ than MSD transplantation, suggesting that HID transplantation might have a superior GVL effect than MSD transplantation for Ph- high-risk B-ALL patients.Trial registration::ClinicalTrials.gov: NCT01883180, NCT02673008.

Objective:To evaluate the efficacy and safety of bendamustine monotherapy in Chinese patients with relapsed/refractory (R/R) B cell non-Hodgkin lymphoma (B-NHL) .Methods:This prospective, multicenter, open label, single-arm, phase Ⅱ study investigated bendamustine’s efficacy and safety in Chinese patients with R/R B-NHL. A total of 78 patients with B-NHL in 11 hospitals in China from March 2012 to December 2016 were included, and their clinical characteristics, efficacy, and survival were analyzed.Results:The median age of all patients was 58 (range, 24-76) years old, and 69 (88.4% ) patients had stage Ⅲ/Ⅳ disease. 61 (78.2% ) patients were refractory to previous treatments. Patients received a median of 4 (range, 1-10) cycles of bendamustine treatment. The overall response rate was 61.5 (95% CI 49.8-72.3) % , the median response duration was 8.3 (95% CI 5.5-14.0) months, and the complete remission (CR) rate was 5.1 (95% CI 1.4-12.6) % . In the full analysis set, median progression-free survival (PFS) and median OS were 8.7 (95% CI 6.7-13.2) months and 25.5 months (95% CI 14.2 months to not reached) , respectively, after a median follow-up of 33.6 (95% CI 17.4-38.8) months. Lymphopenia (74.4% ) , neutropenia (52.6% ) , and leukopenia (39.7% ) , thrombocytopenia (29.5% ) and anemia (15.4% ) were the most common grade 3-4 hematologic adverse events (AE) . The most frequent non-hematologic AEs included nausea (43.6% ) , vomiting (33.3% ) , and anorexia (29.5% ) . Univariate and multivariate analysis showed that <4 cycles of bendamustine treatment was a poor prognostic factor for PFS ( P=0.003) , and failure to accept fludarabine containing regimen was a poor prognostic factor for OS ( P=0.009) . Conclusion:Bendamustine monotherapy has good efficacy and safety in the treatment of patient with R/R B-NHL.

BACKGROUND: The prevalence of obesity and overweight in childhood has increased dramatically over the past decades globally. Thus, the risk factors of overweight and obesity in children and adolescents must be studied. OBJECTIVES: This study aimed to reveal the prevalence of childhood obesity and examine the relationship between socioeconomic status (SES) and z-body mass index (z-BMI) via parental obesity and dietary intake using path analysis. METHODS: Stratified cluster sampling was used to select 17,007 participants aged 6-12 years on two avenues per region in urban, suburban, and rural areas. Path analysis was conducted to examine the mediators between SES and z-BMI. RESULTS: The prevalence rates of overweight and obesity were 13.36% and 8.60%, respectively, and were positively correlated with the father's education level, family income, a birth weight > 3000g, a parental obesity history, vegetable intake and red meat intake (all P < 0.05). Four mediators (paternal obesity history, red meat intake, vegetable intake, and nutritional supplements) were observed, and the four path analyses were significant (all P < 0.05). The adjusted total effects on z-BMI were significant for income (β CONCLUSIONS The prevalence of overweight/obesity in children was notable, and the relationship between SES and z-BMI was mediated by paternal obesity history and dietary intake.

Objective To explore the effect of the combination of Internet +and medical care in the compliance of the discharged children with Kawasaki disease. Methods A total of 76 children with Kawasaki disease who were discharged from a third-grade hospital were selected. The control group (37 cases) and the intervention group (39 cases) were selected by random sampling at different time intervals. Both groups received routine guidance during hospitalization. The intervention group was admitted to the WeChat work platform (WeChat group, WeChat public number) and"Almond"doctors' follow-up platform. Six months after discharge, the Kawasaki disease basic knowledge questionnaire was used and the medication compliance (Morisky medication compliance scale) was used for investigation and evaluation. Results The score of the Kawasaki disease basic knowledge questionnaire was (53.38±13.66) points in the control group, and (62.36± 13.48) points in the intervention group, there was significant difference (t=-3.388, P<0.05).The score of Morisky medication compliance scale was (5.97 ± 0.94) points in the control group, and (6.53 ± 1.40) points in the intervention group, and there was significant difference (t=-2.112, P<0.05). Conclusions The integration ofInternet+and medical care can improve the compliance of the parents of children with Kawasaki disease, and can be used in the continuous nursing of children with chronic disease.

Objective: To investigate the status of uncertainty in illness and its influencing factors among parents of children with Kawasaki disease complicated by coronary artery aneurysm. Methods: A total of 102 parents of children with Kawasaki disease complicated by coronary artery aneurysms were investigated by General Information Questionnaire, Parent's Perception of Uncertainty Scale, Hospital Anxiety and Depression Scale. Results: The total sore of Parent′s Perception of Uncertainty Scale was (91.02 ± 13.14) points; that of anxiety was (14.35 ± 3.93) points; while that of depression was (13.81 ± 3.92) points. The uncertainty in illness among parents was influenced by coronary artery aneurysm grading, source of medical expenses, education level, understanding of the disease, average family income (F=2.535-8.740, all P<0.05), relationship with the child, work status (t =2.057, -2.489, P<0.05). Multiple stepwise regression analysis showed that depression, understanding of the disease, source of medical expenses had a significant impact on the illness uncertainty of parents (F=13.695, P<0.05). Conclusions The uncertainty in illness among parents of children with Kawasaki disease complicated by coronary artery aneurysm had a higher level. The doctors and nurses should pay attention to the effect of uncertainty in illness on the parents of children and take targeted intervention measures to help parents reduce uncertainty in illness, thereby improving the quality of life.

Objective: To explore the association between dietary supplementation during pregnancy and low birth weight. Methods: 11 311 pregnant women who had regularly visited outpatient gynecology clinic of Wuhan Women and Children Medical Center with intention to delivery in the hospital were recruited in the cohort between September 2012 and October 2014. Social-demographic characteristics of pregnant women and spouses, dietary supplementation during pregnancy, pre-pregnancy body mass index (BMI), exercise in the third trimester, work during pregnancy, pregnancy complications and related pregnancy information were collected through self-designed questionnaires, maternal health manuals and medical records. Birth weight of the newborns was measured. Non-conditional multivariate logistic regression analysis was used to determine the correlation between dietary supplementation and low birth weight. Results: 11 311 pregnant women were (28.21±3.70) years old, and they gave birth to 477 low birth weight newborns (4.2%). Iron supplementation during the whole period of pregnancy (OR (95%CI): 0.60 (0.43-0.63)) and folic acid supplementation during the early pregnancy (OR (95%CI): 0.74 (0.60-0.90)) were negatively associated with low birth weight. Conclusion Supplementation of iron during the whole period of pregnancy and folic acid during the early pregnancy would reduce the risk of low birth weight.
