The association of maternal vaginal bleeding and progesterone supplementation in early pregnancy with offspring outcomes: a prospective cohort study. BMC Pregnancy Childbirth 2022; 22:390. [PMID: 35513779 PMCID: PMC9074309 DOI: 10.1186/s12884-022-04711-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Accepted: 04/26/2022] [Indexed: 11/25/2022] Open
Abstract
Background Progesterone is widely used to improve the adverse pregnancy outcomes related to vaginal bleeding during early pregnancy. However, the evidence of its effectiveness is equivocal. Methods Six thousand six hundred fifteen mother-infant pairs from Tongji Maternal and Child Health Cohort (TMCHC) were involved in the study. Information on vaginal bleeding, progesterone administration in early pregnancy were obtained at enrolment. Birth outcomes were obtained from the hospital notes. Body weight of the infants at 12 months of age was collected by telephone interview. Multivariable logistic regression was conducted to estimate the effect of vaginal bleeding and progesterone administration in early pregnancy on birth outcomes and weight status of infants at 12 months of age. Results 21.4% (1418/6615) participants experienced bleeding in early pregnancy, and 47.5% (674/1418) of them were treated with progesterone. There were no significant associations between progesterone supplementation in early pregnancy and offspring outcomes. Compared to women without bleeding or any therapy, women with bleeding and progesterone therapy experienced increased risk of preterm (OR 1.74, 95% CI 1.21–2.52), and delivering a small-for-gestational-age (SGA) (OR 1.46, 95% CI 1.07–1.98) or low birth weight (LBW) (OR 2.10, 95% CI 1.25–3.51) neonate, and offspring of them had an increased risk of weight for age z-score (WAZ) < -1 at 12 months of age (OR 1.79, 95%CI 1.01–3.19). Conclusions Offspring of mothers with bleeding and progesterone therapy were more likely to be a premature, SGA or LBW neonate, and had lower weight at 12 months of age. Progesterone supplementation may have no beneficial effect on improving adverse offspring outcomes related to early vaginal bleeding. Trial registration TMCHC was registered at clinicaltrials.gov as NCT03099837 on 4 April 2017.

Abstract
Over the past few decades, neuroimaging has become a ubiquitous tool in basic research and clinical studies of the human brain. However, no reference standards currently exist to quantify individual differences in neuroimaging metrics over time, in contrast to growth charts for anthropometric traits such as height and weight1. Here we assemble an interactive open resource to benchmark brain morphology derived from any current or future sample of MRI data ( http://www.brainchart.io/ ). With the goal of basing these reference charts on the largest and most inclusive dataset available, acknowledging limitations due to known biases of MRI studies relative to the diversity of the global population, we aggregated 123,984 MRI scans, across more than 100 primary studies, from 101,457 human participants between 115 days post-conception to 100 years of age. MRI metrics were quantified by centile scores, relative to non-linear trajectories2 of brain structural changes, and rates of change, over the lifespan. Brain charts identified previously unreported neurodevelopmental milestones3, showed high stability of individuals across longitudinal assessments, and demonstrated robustness to technical and methodological differences between primary studies. Centile scores showed increased heritability compared with non-centiled MRI phenotypes, and provided a standardized measure of atypical brain structure that revealed patterns of neuroanatomical variation across neurological and psychiatric disorders. In summary, brain charts are an essential step towards robust quantification of individual variation benchmarked to normative trajectories in multiple, commonly used neuroimaging phenotypes.

Association of Maternal Longitudinal Hemoglobin with Small for Gestational Age during Pregnancy: A Prospective Cohort Study. Nutrients 2022; 14:nu14071403. [PMID: 35406016 PMCID: PMC9003216 DOI: 10.3390/nu14071403] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 03/26/2022] [Accepted: 03/26/2022] [Indexed: 02/06/2023] Open
Abstract
Background: Few studies have investigated the association of maternal longitudinal hemoglobin (Hb) with small for gestational age during pregnancy. The current study examined the associations of maternal Hb concentrations and Hb changes throughout the middle and late stages of pregnancy with small for gestational age (SGA) in a large prospective cohort study. Methods: This was a prospective cohort study, which enrolled pregnant women at 8−16 weeks of gestation and followed up regularly. Maternal Hb concentrations were measured at the middle (14−27 weeks) and late (28−42 weeks) stages of pregnancy, and the Hb change from the middle to late stage of pregnancy was assessed. The Log-Poisson regression model was used to identify the association of maternal Hb with SGA, including the implications of Hb during specific pregnancy periods and Hb change across the middle to late stages of pregnancy. Of the total 3233 singleton live births, 208 (6.4%) were SGA. After adjusting for potential confounders, compared with Hb 110−119 g/L, Hb ≥ 130 g/L at late pregnancy was significantly associated with a higher risk of SGA (adjusted RR: 2.16; 95% CI: 1.49, 3.13). When Hb changes from the middle to late stages of pregnancy were classified by tertiles, the greatest change in the Hb group (<−6.0 g/L) was significantly associated with a lower risk of SGA (adjusted RR: 0.56; 95% CI: 0.37, 0.85) compared with the intermediate group (−6.0~1.9 g/L). In conclusion, for women at low risk of iron deficiency, both higher Hb concentrations in late pregnancy and less Hb reduction during pregnancy were associated with an increased risk of SGA.

Abstract
Objective: To analyze the eligibility of empirical antibiotic therapy in culture positive sepsis in the pediatric intensive care unit (PICU), and to explore the application of antibiotic de-escalation (ADE) in children with sepsis and its impact on prognosis. Methods: A total of 123 children with sepsis-associated organ dysfunction or septic shock admitted to the PICU of Shengjing Hospital of China Medical University from January 2018 to December 2020 were retrospectively analyzed. The general information, laboratory tests, the use of empirical anti-bacterial drugs and the application of ADE were collected. According to the adjustment of anti-bacterial drugs, these children were divided into ADE group and non-ADE group. Comparisons between groups were performed with unpaired Student t test, or Mann-Whitney U test, or chi-square test or Fisher exact test. Results: In these 123 children, 70 were males and 53 were females, the age was 11.4 (2.8, 56.5) months. Body fluid culture was detected positive in 41 children including 3 children (7.3%) who received inadequate empirical antibiotic therapy and 38 children (92.7%) who received adequate empirical antibiotic therapy. Excluding 10 children who received appropriate therapy, 28 received unnecessary broad-spectrum antibiotics. There were no significant differences regarding the PICU all-cause mortality rates, length of PICU stay, hospitalization cost, duration of mechanical ventilation, as well as incidences of re-infection between the ADE group (n=46) and non-ADE group (n=77) (all P>0.05). However, among the 101 children who have used antibiotics against multidrug-resistant organism, the duration of such antibiotics use in ADE group (n=43) was shorter than that in non-ADE group (n=58) (5.0 (4.0, 12.0) vs. 9.5 (7.0, 13.0) d, Z=-3.14, P=0.002). Conclusions: Overuse of unnecessary broad-spectrum empirical antibiotics is very common, but the application of ADE is rather disappointing. ADE can reduce the use of anti-bacterial drugs against multi-drug resistant bacteria without significant adverse effects on prognosis in children with sepsis.

Abstract
Abstract
It has been recognized that ultra-high strength and high modulus ultra-highly drawn Polyethylene (PE) fiber is produced from the formation of extended chain crystal. Nevertheless, whether extended chain crystal exists in gel spinning ultra-highly drawn PE fiber is still an unsettled question. In this work, decalin was adopted as a solvent for PE gel spinning. By means of thermal analysis, X-ray diffraction methods etc, the existence of extended chain crystal was explored. Reasons for confusion in previous studies of this problem were discussed.
In PE fiber from 3 wt-°/o dope, extended chain crystal starts to form during draw ratios over 20. When draw ratio equals 42, the content of extended chain crystal roughly equals that of folded chain crystal. The melting point of extended chain crystal is 6°C higher than that of folded chain crystal. They are 145.5° C and 150° C to 152.5° C respectively. The latter would slightly rise with arise of draw ratio.
Multi-crystallization behavior of annealed PE fiber was determined and discussed. It was also confirmed that there is a linear logarithm relationship between thermal shrinkage (internal stresses) and fiber moduli.

Abstract
BACKGROUND The evidence on the relationship between diet diversity in early life and allergic outcomes was few and inconsistent. We sought to determine the association of food diversity in the first year of life with allergic outcomes in the second year. METHODS Two thousand two hundred fifty-one mother-infant pairs from Tongji Maternal and Child Health Cohort (TMCHC) were involved in the study. Information on complementary foods introduction was obtained by telephone interview at 6- and 12-month postpartum follow-up. Any doctor-diagnosed allergic diseases in the second year were recorded at 2-year postpartum follow-up. Food allergies in infancy were assessed and self-reported by mothers at each postpartum follow-up. Multivariable logistic regression was used to examine the effect of food diversity at 6 and 12 months of age on later allergic diseases and food allergy. RESULTS A total of 135 (6.0%) infants reported allergic diseases at between 1 and 2 years of age. Independent of food allergy history of infants and other potential confounders, less food diversity at 6 months of age was associated with increased risk of later allergic diseases (OR 2.17, 95% CI 1.04-4.50 for 0 vs. 3-6 food groups). By 12 months of age, significant inverse associations with later allergic diseases (OR 2.35, 95% CI 1.03-5.32 for 1-5 vs. 8-11 food groups, and OR 1.98, 95% CI 1.16-3.37 for 6-7 vs. 8-11 food groups) and food allergy (OR 2.10, 95% CI 1.29-3.42 for 1-5 vs. 8-11 food groups) were observed. Children with higher food diversity in both periods had the lowest risk of allergic diseases during the second year of life. CONCLUSIONS A more diverse diet within the first year of life was associated with reduced risk of allergic diseases at 1-2 years of age. Introducing higher diversity of foods from 6 to 12 months of age might be an effective strategy to improve the allergy outcomes of infants in later life.

Abstract
Background Approximately 2%-8% of non-small-cell lung cancer (NSCLC) harbors concurrent epidermal growth factor receptor (EGFR) sensitizing mutation and mesenchymal–epithelial transition factor (MET) amplification prior to EGFR-tyrosine kinase inhibitor (EGFR-TKI) therapy. This study aimed to investigate the optimal first-line therapeutic options for patients with concurrent EGFR-mutant, MET-overexpressed/amplified advanced NSCLC. Methods A total of 104 treatment-naïve patients with EGFR-mutant de novo MET-overexpressed advanced NSCLC were identified using immunohistochemistry and stratified to four groups according to treatment regimen: EGFR-TKI monotherapy (n = 48), EGFR-TKI combined with either crizotinib (n = 9) or chemotherapy (n = 12), and chemotherapy (n = 35). A subpopulation of 28 patients was also tested with next-generation sequencing (NGS). Objective response rate (ORR) and progression-free survival (PFS) outcomes were analyzed according to treatment strategies and molecular features. Results All the patients (n = 104) achieved ORR of 36.5% and median PFS (mPFS) of 7.0 months. Baseline clinicopathologic characteristics were similar among the four treatment groups. Compared with chemotherapy, EGFR-TKI monotherapy or EGFR-TKI combination therapy achieved significantly higher ORR (P < 0.001) and longer mPFS (P = 0.003). No ORR or PFS difference was observed between EGFR-TKI monotherapy and combination therapy. In the NGS-identified population (n = 28), patients who received EGFR-TKI plus crizotinib (n = 9) achieved similar ORR (88.9% versus 57.9%, P = 0.195) and mPFS (9.0 versus 8.5 months, hazard ratio 1.10, 95% confidence interval 0.43-2.55, P = 0.45) than those who received EGFR-TKI monotherapy (n = 19), regardless of MET copy number status. Grade 3/4 rashes were significantly more among patients who received EGFR-TKI plus crizotinib (P = 0.026). Conclusions Our findings provided clinical evidence that patients with concurrent EGFR sensitizing mutation and de novo MET amplification/overexpression could benefit from first-line EGFR-TKI monotherapy. Concomitant EGFR sensitizing mutation and MET overexpression/amplification were detected in 2.6% of lung cancer patients. EGFR-TKI monotherapy elicited a higher response rate and longer PFS than chemotherapy. EGFR-TKI with or without crizotinib elicited comparable PFS regardless of MET copy number. EGFR-TKI monotherapy achieved lower number of grade 3/4 adverse events than EGFR-TKI plus crizotinib.

Abstract
The associations among maternal diet, birth weight, and gestational weight gain are still inconclusive. This study aimed to investigate the associations between maternal dietary patterns and birth weight, and further explore whether GWG mediates these associations. A total of 3,334 pregnant women who completed a validated semi-quantitative food frequency questionnaire from the Tongji Maternal and Child Health Cohort were included. Dietary patterns were extracted by using principal component analysis. Regression models and mediation analyses were performed to explore the associations between dietary patterns and birth weight and the effects of GWG on these associations. Five dietary patterns were identified: "Beans-vegetables," "Fish-meat-eggs," "Nuts-whole grains," "Organ-poultry-seafood" and "Rice-wheat-fruits." Only women following the "Beans-vegetables" pattern had heavier newborns (β = 47.39; 95% CI: 12.25, 82.54). Women following the "Beans-vegetables" pattern had significantly lower GWG (β = -0.7; 95% CI: -1.15, -0.25) and had a 16% lower risk of excessive GWG and 11% higher odd of adequate GWG. The association between the "Beans-vegetables" pattern and birth weight was negatively mediated by GWG. A dietary pattern enriched in beans and vegetables is beneficial for effectively controlling GWG and increasing birth weight. GWG serves. Clinical Trial Registry: This trial was registered at ClinicalTrials.gov (NCT03099837).

Abstract
Objective: The results of syphilis antibody screening in Peking University Third Hospital from 2016 to 2020 were analyzed,to explore the characteristics of sex, age and distribution of patients with positive syphilis antibody. Methods: A retrospective study was conducted to collect the results of syphilis antibody in outpatients and inpatients of Peking University Third Hospital from 2016 to 2020. Syphilis antibodies were screened in 626 528 patients aged 1-98 years, 4 232 were retested positive by TPPA test, including 2 132 males (50.4%) and 2 100 females (49.6%). Chemiluminescence immunoassay (CMIA) was used for syphilis antibody screening, and Treponema pallidum particle agglutination (TPPA) test was used for reexamination. SPSS20.0 data statistical analysis software was used to analyze the detection rate, age, sex, department and clinical diagnosis of patients with positive syphilis antibody by χ² test. Results: Among 626 528 patients who were positive for treponema pallidum antibody screening, 4 232 were retested positive by TPPA test, accounting for 0.68% of the total number of patients tested. The number of syphilis tests increased year by year, however the positive detection rate decreased. The positive detection rate of syphilis antibody in 2020 decreased by 18.9% compared with 2016. The positive rate of syphilis antibody in male patients was higher than that in female patients, accounting for 0.80% and 0.59% of the total number of patients tested respectively. The positive rate of syphilis antibody of different genders increased with age, the total positive rate of 0-20, 21-40, 41-60, 61-80,>80 years old were 0.15%, 0.45%, 0.95%, 1.07% and 1.41%, respectively. While the increase rate of males was higher than that of females. The positive rate of male over 80 years old was 18.13 times of the group of 0-20 years old, and 5.54 times in women. The top 6 departments with positive syphilis antibody detection rate were emergency department, oncology department, respiratory department, geriatrics department, endocrinology department and neurology department, and the positive rates were 1.79% (104/5 810),1.46% (55/3 767),1.20% (74/6 167),1.20% (22/1 833),1.10% (32/2 909),1.09% (94/8 624), respectively. From the analysis of clinical diagnosis, the proportion of positive syphilis antibody in infertile patients (0.64%, 672/104 911) was higher than that in naturally conceived patients (0.10%, 24/23 969). Conclusions: From 2016 to 2020, the positive detection rate of syphilis antibody in Peking University Third Hospital decreased year by year. However, the positive detection rate increased with the age of patients. The positive rate of syphilis antibody in male was higher than that in female. The positive rate of syphilis antibody in pregnant women was lower than that in infertile patients.

Abstract
STUDY DESIGN Invited Clinical Commentary BACKGROUND: Performance related musculoskeletal disorders (PRMD) are common in instrumental musicians and often affect the upper extremities. These overuse injuries typically result from inadequate attention to the musculoskeletal demands required for the high-level performance of musician-students and experienced instrumentalists.1 PRMDs often interfere with career trajectory, and in extreme cases, can be career ending. Many clinicians and healthcare practitioners treating upper extremity injuries are not familiar with the specific demands faced by instrumental musicians and how to tailor treatment and prevention strategies to the specific risks and occupational needs of each instrumental group. PURPOSE OF THE STUDY This paper describes an evidenced-based framework for the assessment, prevention, and treatment of musculoskeletal musician injuries to provide clinicians with an instrument-specific, and musician-centered guide for practice. We synthesized available literature on instrumental ergonomics, biomechanical demands, and upper extremity injuries to highlight the risks and common upper-extremity pathologies, focusing on the specific demands of instrumental groups: piano, high strings (violin and viola), low strings (cello and bass), percussion, woodwinds, and brass. Targeted assessment, prevention, and treatment strategies are reviewed in this context to provide healthcare providers with an evidence-based framework to approach the treatment of PRMD to mitigate incidence of injury during practice and performance. METHODS A comprehensive search of electronic databases was conducted including all study designs. RESULTS This review describes risk factors for PRMD in instrumental musicians, strategies to prevent misuse and performance injury, and musician-centered interventions to allow playing while reducing risk of misuse. CONCLUSION The suggested assessment and treatment framework can assist clinicians with a customized patient-centered approach to prevention and treatment by addressing the gap in clinical knowledge with the goal of ultimately reducing the incidence and severity of PRMD in musicians.

Abstract
OBJECTIVE To investigate the association of the maternal serum albumin (MAlb) level with fetal growth and fetal growth restriction (FGR) risk in term-born singletons. DESIGN Prospective cohort study. SETTING Four hospital maternity units of the Tongji Maternal and Child Health Cohort study initiated from September 2013 to April 2016 at Wuhan City, in central China. PATIENT(S) A total of 3,065 mother-offspring pairs. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Fetal growth was evaluated by birth weight (BW) and birth length. Fetal growth restriction was defined as BW below the 10th percentile. RESULT(S) All MAlb levels were within the upper limit of normal. After adjustment for liver function parameters, inflammatory indicators, and others, a reverse U-shaped relationship between MAlb and fetal growth was observed. Specifically, BW increased significantly with an increasing MAlb level when the MAlb level was <36.1 g/L (per g/L: β = 36.8; 95% CI, 0.8, 72.7) but decreased with increasing the MAlb level when the MAlb level was >36.1 g/L (per g/L: β = -15.1; 95% CI, -21.2, -8.9). There was a similar association between MAlb and birth length. Furthermore, the adjusted odd ratios of FGR across increasing tertiles of the MAlb levels were 1.0 (reference), 1.1 (0.7, 1.8), and 1.7 (1.0, 2.6). CONCLUSION(S) There was a reverse U-shaped association between MAlb and fetal growth. A higher MAlb level was associated with an increased risk of FGR. CLINICAL TRIAL REGISTRATION NUMBER NCT03099837.

Abstract
Objective: To analyze the status of early use of oral β-blocker and its relationship with in-hospital outcomes in eligible patients with acute coronary syndrome (ACS). Methods: The study was based on the Improving Care for Cardiovascular Disease in China (CCC)-ACS project. The data of ACS patients that collected during 2014 to 2019 from 230 collaborating hospitals across China were analyzed. Propensity score matching method and Cox multivariate regression analysis were used to analyze the association between early use of oral β-blocker and in-hospital outcomes within 15 days. Results: A total of 38 663 eligible ACS patients were included in this study. The mean age was (57.0±9.0), and 78.8% of the ACS patients (30 470/38 663) were male. The proportion of early use of oral β-blockers was 64.9% (25 112/38 663), but varied substantially, in the 230 hospitals with a range from 0 to 100%. Compared with the patients no early use of oral β-blocker, the patients receiving early oral β-blocker had significantly lower incidence of major cardiovascular adverse events (MACEs) (3.4% (395/11 536) vs. 2.9%(339/11 536), P=0.036)and less occurrences of heart failure (2.7% (316/11 536) vs. 2.1% (248/11 536), P=0.004). Multivariate Cox regression analyses showed the patients receiving early oral β-blocker had 15.5%, 23.1%, and 35.3% lower risks of MACEs, heart failure and cardiogenic shock respectively than the patients no early oral β-blocker. Conclusions: Compared with the patients no early oral β-blocker, the patients receiving early oral β-blocker had lower risks of MACEs events, heart failure and cardiogenic shock. However, the early use of oral β-blocker in ACS patients was generally insufficient with huge differences among different hospitals in China.

Abstract
Objective: To analyze the current status, trend and predictors of thromboembolism risk assessment in patients hospitalized with non-valvular atrial fibrillation (NVAF) in tertiary hospitals in China. Methods: The study was based on data from the Improving Care for Cardiovascular disease in China (CCC)-Atrial Fibrillation (AF) project. About 10% of the tertiary hospitals in each geographic-economic stratum were recruited. Participating hospitals reported the first 10 to 20 patients with a discharge diagnosis of atrial fibrillation monthly. From February 2015 to December 2019, a total of 49 104 NVAF patients from 151 tertiary hospitals in 30 provinces, municipalities and autonomous regions were enrolled. Clinical data of the patients was collected. The proportion of NVAF patients receiving thromboembolism risk assessment, variations in the proportion between different hospitals, the time trend of the application of thromboembolism risk assessment, and the predictors of the application of thromboembolism risk assessment were analyzed. Results: The age of the NVAF patients was (68.7±12.1) years, 27 709 patients (56.4%) were male. Only 17 251 patients (35.1%) received thromboembolism risk assessment. The proportion varied substantially between hospitals with the lowest value of 0 and the highest value of 100%. Among the hospitals, which enrolled more than 30 patients, no patients received thromboembolism risk assessment in 18.4% (26/141) of the hospitals, more than 50% of the patients received thromboembolism risk assessment in 21.3% (30/141) of the hospitals, and all the patients received thromboembolism risk assessment in only 1 hospital. The proportion of NVAF patients receiving thromboembolism risk assessment was 16.2% (220/1 362) in the first quarter of 2015, and significantly increased to 67.1% (1 054/1 572) in the last quarter of 2019 (P<0.001). Patients' characteristics were associated with the application of thromboembolism risk assessment. The odds of receiving thromboembolism risk assessment was lower in male patients compared to female patients(OR=0.94,95%CI 0.89-0.99), lower in patients with acute coronary syndrome or other cardiovascular diseases compared to those with AF as the primary admission reason (OR=0.59, 95%CI 0.55-0.63, OR=0.52, 95%CI 0.45-0.61, respectively), and lower in patients with paroxysmal, persistent and long-standing/permanent AF compared to those with first detected AF (OR=0.62, 95%CI 0.57-0.67, OR=0.72, 95%CI 0.66-0.79, OR=0.57, 95%CI 0.52-0.64, respectively). The odds was higher in patients with a history of hypertension, heart failure, stroke/TIA, and previous anticoagulant therapy compared to those without the above conditions (OR=1.17, 95%CI 1.11-1.23, OR=1.18, 95%CI 1.07-1.30, OR=1.17, 95%CI 1.08-1.27, OR=1.28, 95%CI 1.19-1.37, respectively) (P all<0.05). Conclusion: Thromboembolism risk assessment was underused in patients hospitalized with NVAF in tertiary hospitals in China, and there were substantial variations between hospitals in the application of thromboembolism risk assessment. The application of thromboembolism risk assessment in tertiary hospitals has been improved in recent years, but there is still plenty of room for future improvement. Patients' characteristics could affect the application of thromboembolism risk assessment in China.

Abstract
BACKGROUND The association between iron supplementation and gestational diabetes mellitus (GDM) is still inconclusive, and this association has not been extensively studied in relation to plasma ferritin in the early second trimester. OBJECTIVES We aimed to prospectively examine the independent and combined associations of plasma ferritin concentrations and iron supplement use with GDM. METHODS We studied 2117 women from the Tongji Maternal and Child Health Cohort in Wuhan, China. Plasma ferritin around 16 weeks' gestation was measured by ELISA kits and information on iron supplement use was collected by questionnaires. GDM was diagnosed by a 75-g oral-glucose-tolerance test (OGTT) at 24-28 weeks' gestation. A log-Poisson regression model was used to estimate the RR of GDM associated with plasma ferritin and iron supplementation. RESULTS The median and IQR of plasma ferritin was 52.1 (29.6-89.9) ng/mL, and 863 (40.8%) participants reported use of iron supplements during the second trimester. A total of 219 (10.3%) participants developed GDM. Adjusted RRs (95% CIs) for GDM across increasing quartiles of plasma ferritin were 1.00 (reference), 2.14 (1.37, 3.34), 2.03 (1.30, 3.19), and 2.72 (1.76, 4.21), respectively. After adjustment, supplemental iron ≥60 mg/d during the second trimester was associated with an increased risk of GDM compared with nonusers (RR: 1.37; 95% CI: 1.02, 1.84). CONCLUSIONS Both elevated plasma ferritin concentrations in the early second trimester and use of ≥60 mg/d of supplemental iron during pregnancy are independently associated with increased risk of GDM. Further clinical trials with precision nutrition approaches considering both baseline iron status and supplement use are needed to evaluate the benefits and risks of iron supplementation during pregnancy.

Abstract
OBJECTIVE To explore the relationships between hepatitis B virus (HBV) DNA, HBV RNA and hepatitis B surface antigen (HBsAg) and to evaluate their predictive value for mother-to-child transmission of HBV. DESIGN An observational cohort study. SETTING First Hospital of Jilin University. POPULATION HBsAg-positive and hepatitis B e antigen (HBeAg) -positive pregnant women were recruited. METHODS Blood samples were collected from mothers before delivery, and HBV infection of infants was evaluated at 7 months of age. RESULTS Overall, 268 mothers and 271 infants were enrolled. HBV DNA and HBsAg levels were correlated (rs = 0.699; P < 0.001), and HBV DNA (rs = 0.500; P < 0.001) and HBsAg (rs = 0.372; P < 0.001) were both correlated with HBV RNA. The areas under the curve for HBV DNA, HBsAg and HBV RNA for prediction of infection were 0.69 (95% CI 0.57-0.82), 0.63 (95% CI 0.51-0.76) and 0.65 (95% CI 0.52-0.78), respectively. Higher HBV DNA (odds ratio [OR] 4.77, 95% CI 1.44-15.86), higher HBsAg (OR 4.13, 95% CI 1.12-15.25) and higher HBV RNA (OR 3.19, 95% CI 1.09-9.32) were risk factors for HBV infection. Analysis of the HBV DNA-RNA-HBsAg Score revealed that it was an independent predictive factor for mother-to-child transmission (the OR of Score 3 was 8.81, 95% CI 2.79-27.82). CONCLUSION HBV DNA, HBV RNA and HBsAg were correlated in HBeAg-positive pregnant women. HBsAg could be considered as a substitute marker of HBV DNA for HBeAg-positive pregnant women in low-income regions. We should pay special attention to pregnant women with high levels of all three markers. TWEETABLE ABSTRACT HBsAg could be considered as a substitute marker of HBV DNA for HBeAg-positive pregnant women in low-income regions. Special attention should be given to pregnant women with high levels of all three markers (HBV DNA, HBV RNA and HBsAg).

Abstract
Chronic sclerosing sialadenitis of the submandibular gland (also known as Küttner tumor) is characterized by concomitant swelling of the submandibular glands secondary to strong lymphocytic infiltration and fibrosis. The pathogenesis of this disease has been unclear, but it is associated with immune disorders. ADAMTS18 is a member of the ADAMTS superfamily of extracellular proteinases. In this study, we showed that Adamts18 is highly expressed in submandibular salivary gland (SMG) during embryonic development and decreases but is retained in adult SMG tissue in mice. Adamts18 deficiency led to reduced cleft formation and epithelial branching in embryonic SMG before embryonic day 15.5 in mice. No significant histologic changes in the later stages of branching or the morphology of SMG were detected in Adamts18-/- mice. However, Adamts18 deficiency causes spontaneous SMG fibrogenesis and fibrosis in adult mice. At 8 wk of age, Adamts18-/- mice began to manifest the first signs of pathologic changes of mild fibrosis and CD11b+ cell infiltration in SMG tissues. At ≥8 mo, all male and female Adamts18-/- mice developed unilateral or bilateral SMG scleroma that is similar to patients with chronic sclerosing sialadenitis of the submandibular gland. Adamts18-/- mice also showed secretory dysfunction and severe dental caries. Histologically, SMG scleroma is characterized by progressive periductal fibrosis, acinar atrophy, irregular duct ectasis, and dense infiltration of IgG-positive plasma cells. A significant infiltration of CD4+ T lymphocytes and CD11b+ monocytes and macrophages was also detected in the SMG scleroma of Adamts18-/- mice. The levels of TGF-β1, IL-6, and IL-33 were significantly increased in Adamts18-/- SMGs, which induces chronic inflammation and myofibroblast activation, ultimately leading to fibrosis. This study indicates that Adamts18 regulates the early branching morphogenesis of embryonic SMG and plays a role in protecting from spontaneous SMG fibrogenesis via modulating local inflammation, autoimmune reaction, and myofibroblast activation in adult mice.

Abstract
Objective: To identify factors associated with persistent subretinal fluid (SRF) after scleral buckling and to evaluate surgical outcomes of patients with primary rhegmatogenous retinal detachment (RRD). Methods: Cross-sectional study and cohort study. This study included 104 patients (104 eyes) who underwent scleral buckling for repair of RRD between January 2016 and June 2017. Several statistically significant risk factors associated with SRF were screened out with univariate analysis. Then independent risk factors were determined with multivariate stepwise logistic regression analysis. Examinations were taken preoperatively, at 1, 3, 6, and 12 months postoperatively, and thereafter every six months. Patients were divided into two groups depending on the presence or absence of persistent SRF on optical coherence tomography at 1 month. Results: Persistent SRF occurred in 69.2% (72/104) of patients. In multivariate analysis, younger age (OR=32.860, 95%CI=3.636-296.986, P=0.002), high myopia (OR=7.229, 95%CI=1.217-42.94, P=0.03) and macula-involving retinal detachment (OR=357.397, 95%CI=29.761-4292.0, P=0.000) were associated with persistent SRF. Best corrected visual acuity in patients with SRF at 1 month (0.71±0.18 vs. 0.58±0.11; t=4.047, P<0.01) and 3 months (0.55±0.15 vs. 0.43±0.12; t=3.914, P<0.01) was worse than that in patients with absence of SRF. Best corrected visual acuity in patients with SRF was 0.44±0.16 at 6 months, 0.37±0.12 at 12 months and 0.36±0.10 at the last follow-up, with no significant difference from patients without SRF at the three time points (0.39±0.13, 0.38±0.12 and 0.35±0.09; t=1.643, -0.202, 0.464; P>0.05). Conclusions: RRD patients with younger age, high myopia and macular involvement were more likely to develop persistent SRF after scleral buckling. The presence of persistent SRF slowed visual recovery but did not influence the final visual outcomes. (Chin J Ophthalmol, 2021, 57: 426-432).

Abstract
Abstract
Objectives
Concerns relative to excessive iron intake are raised when high iron status exposure has been linked in observational studies to a greater risk of gestational diabetes mellitus (GDM). We aimed to examine the association between iron intake during pregnancy and GDM risk in Chinese women.
Methods
The study included 2174 pregnant women from the Tongji Maternal and Child Health Cohort (TMCHC), a prospective cohort in Wuhan, China. Iron intakes from food and supplementation prior to GDM diagnosis were assessed using a validated food frequency questionnaire (FFQ) and a detailed supplement questionnaire collected at 13–28 weeks of gestation. GDM was ascertained by an oral glucose tolerance test at 24–28 weeks of gestation. Odd ratios (ORs) of GDM in relation to categories of iron intake (i.e., quartiles of total and food iron intake, categories of supplemental iron intake [0, 0–30, >30 mg/day]) were estimated using logistic regression models, with adjustment for demographic, dietary and lifestyle factors.
Results
A total of 242 (11.1%) women were diagnosed with GDM. The adjusted ORs (95% CIs) for the risk of GDM associated with the higher quartiles compared with the lowest quartile of total iron intake were 1.44 (0.89, 2.33), 2.03 (1.27, 3.25), and 2.86 (1.84, 4.43), respectively (P for trend < 0.001). This association was entirely driven by supplemental iron intake. Women with supplemental iron intake > 30 mg/day during pregnancy had an OR for GDM of 2.32 (95% CI: 1.60, 3.36). Moreover, the significant positive effect of supplemental iron was mainly attributed to iron supplementation during mid-pregnancy (≥60 vs. 0 mg/day, OR: 1.46, 95% CI: 1.00, 2.13), while no effect of iron supplementation during early pregnancy was observed. No significant association was found between food iron intake and GDM.
Conclusions
Higher supplemental iron intake during pregnancy was significantly associated with elevated GDM risk. Adverse effect of indiscriminate iron supplementation, especially inappropriate supplementation during mid-pregnancy, would likely outweigh benefits for maternal health.

Abstract
Associations between environmental tobacco smoke (ETS) and the risk of adverse birth outcomes may be confounded. We aimed to clarify the associations of ETS before and during pregnancy with the risk of adverse birth outcomes and determine whether the associations were modified by key potential confounders. A total of 7147 non-smoking mothers from the Tongji Maternal and Child Health Cohort (TMCHC) in Wuhan, China, were included in the final analyses. ETS status was self-reported by pregnant women at their first antenatal care visit before 16 gestational weeks. Information on birth outcomes was extracted from delivery records. Poisson regression was used to identify the association between ETS before and during pregnancy and the risk of adverse birth outcomes. Exposures to ETS before and during pregnancy were reported by 645 (9.0%) and 464 (6.5%) mothers, respectively. Compared with no ETS, continued ETS during pregnancy was associated with an increased risk of preterm birth (PTB) (RR: 1.55, 95% CI: 1.07, 2.25) after adjustment for potential confounders. The association remained consistent in medically indicated PTB and late PTB. The risk of PTB associated with continued ETS during pregnancy was significantly increased in mothers more educated (P for interaction < 0.05). However, the increased risk of low birth weight (LBW) or small for gestational age (SGA) births by ETS during pregnancy was not observed. Exposure to ETS during pregnancy was associated with a higher risk of PTB, but not LBW or SGA births in a Chinese birth cohort.

[PMID: 33961900 DOI: 10.1016/j.diabres.2021.108853] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 04/28/2021] [Accepted: 04/30/2021] [Indexed: 11/25/2022]
Abstract
AIMS Iron supplementation has been recommended for healthy pregnancy, but concerns have been raised regarding the potential adverse effects. We sought to examine the impact of periconceptional iron supplement use on subsequent gestational diabetes mellitus (GDM) risk. METHODS Participants (N = 5101) with information on periconceptional micronutrient supplementation and diagnosis of GDM were involved. Information on iron supplementation and general characteristics were collected at enrollment and follow-up visits. GDM was diagnosed by oral glucose tolerance tests (OGTT) conducted at 24-28 weeks of gestation. Robust Poisson regression model was used to estimate the relative risks (RRs) and 95% confidence intervals (CI) for the effect of iron supplement use on GDM. RESULTS 10.5% of the participants were diagnosed with GDM and the incidence was significantly higher in users with iron >30 mg/d for more than 3 months (Iron >30-L) than in nonusers. Adjusted RRs (95% CI) were 1.53 (1.21, 1.93) in Iron >30-L group, 1.14 (0.80, 1.61) in users with iron >30 mg/d for<3 months (Iron > 30-S) and 1.15 (0.86, 1.54) in users with iron ≤30 mg/d for any duration (Iron ≤30) respectively, compared to nonusers. This link in Iron >30-L group was even stronger (adjusted RR: 1.70, 95% CI: 1.25, 2.31) when restricting the analysis among primiparous and iron-replete participants without family history of diabetes. There were no significant differences in birth outcomes among groups. CONCLUSIONS Periconceptional iron supplementation >30 mg/d for long-term was associated with increased GDM risk. The need and safety of prophylactic iron supplement in iron-replete pregnant women should be reconsidered.

Abstract
We aimed to evaluate the association of the exposure to environmental tobacco smoke (ETS) during pregnancy and infancy with the risk of upper respiratory tract infections (URTI) in infants based on a Chinese birth cohort study. Among 4178 infants who constituted the final study population, 46.8% experienced URTI in their first year of life. The hazard ratios (HR) and 95% confidence intervals (CI) for the risk of URTI were assessed using Cox regression models. Compared with no ETS during pregnancy, continued ETS during pregnancy was independently associated with a higher risk of URTI (HR: 1.36, 95% CI: 1.13, 1.63) after adjustment for potential confounders and also associated with earlier occurrence of URTI (log-rank P = .002). The association remained consistent across the strata defined according to maternal age, number of siblings, sex, and breastfeeding. Exposure to ETS during infancy was associated with URTI only among infants who were breastfed for less than 12 months (P for interaction < 0.05).Furthermore, infants exposed to ETS during both pregnancy and infancy showed the highest HR of 1.46 (95% CI: 1.16, 1.85) for URTI. Efforts should be made to protect pregnant women and infants from the adverse effects of indoor and outdoor ETS.

Abstract
Long winters led to a one-crop-a-year cultivation system until the winter wheat Dongnongdongmai 1 (Dn1) was successfully cultivated in northeast China. This crop variety is resistant to extremely low temperatures (-35 °C). To better understand the adaptability of winter wheat Dn1 to low temperatures, gas chromatography time-of-flight mass spectrometry (GC-TOF/MS) and metabolomics analysis was conducted on the tillering nodes of winter wheat during the overwintering period. Enzyme-regulating genes of the metabolic products were also quantitatively analysed. The metabolomic results for the tillering nodes in the overwintering period showed that disaccharides had a strong protective effect on winter wheat Dn1. Amino acid metabolism (i.e. proline, alanine and GABA) changed significantly throughout the whole wintering process, whereas organic fatty acid metabolism changed significantly only in the late stage of overwintering. This result indicates that the metabolites used by winter wheat Dn1 differ in different overwintering stages. The relationship between field temperature and metabolite changes in winter wheat Dn1 during overwintering periods is discussed, and disaccharides were identified as the osmotic stress regulators for winter wheat Dn1 during the overwintering process, as well as maintenance of the carbon and nitrogen balance by monosaccharides, amino acids and lipids for cold resistance.

Abstract
OBJECTIVE Previous studies have demonstrated that TNFAIP8 is a cancer-promoting gene. However, the role of TNFAIP8 in esophageal cancer (ECa) has not been reported. The aim of this investigation was to investigate the expression of TNFAIP8 in ECa, and to further explore whether it could regulate cisplatin resistance to this cancer via modulating TAF-Iα expression and promote malignant progression of ECa. PATIENTS AND METHODS Quantitative Real Time-PCR (qRT-PCR) was performed to examine the expression of TNFAIP8 in 47 tumor tissue specimens and adjacent ones of ECa patients, and the interplay between TNFAIP8 expression and prognosis of patients with ECa was then analyzed. Further, qRT-PCR was applied to verify TNFAIP8 level in ECa cell lines. In addition, the TNFAIP8 knockdown model was constructed in ECa cisplatin-resistant cell lines including EC-109/DDP and OE19/DDP, and then, CCK8 and transwell assays were performed to analyze the impact of TNFAIP8 on the biological function of ECa cells; meanwhile, the Luciferase reporter gene assay and cell reverse experiments were finally conducted to explore its underlying mechanisms. RESULTS The qRT-PCR results revealed that the TNFAIP8 level in tumor tissue samples of ECa patients was remarkably higher than that in adjacent ones, and the difference was statistically significant. Similarly, the overall survival rate of patients with high expression of TNFAIP8 was lower when compared with patients with low expression of TNFAIP8. EC-109/DDP and OE19/DDP, the ECa cisplatin-resistant cell lines, were successfully constructed; subsequently, it was found that the proliferation, invasiveness, and metastasis ability of ECa cells in TNFAIP8 knockdown group was remarkably decreased compared with those in the sh-NC group. At the same time, the Western blot results illustrated that the expression of TAF-Iαwas remarkably elevated in the TNFAIP8 knockdown group. In addition, the Luciferase reporting assay and cell reverse experiments also demonstrated that there existed a mutual regulation effect between TNFAIP8 and TAF-Iα, which might together affect the malignant progression of ECa. CONCLUSIONS The expression of TNFAIP8 was found remarkably enhanced in ECa tissues and cell lines, which might be closely relevant to the poor prognosis of patients with ECa. Additionally, it was found that TNFAIP8 may regulate cisplatin resistance and promote malignant progression of ECa by modulating TAF-Iα expression.

Abstract
OBJECTIVE Neuroblastoma is the most frequent tumor of sympathetic nervous system in infants. MiRNAs acted as oncogenes or tumor suppressors in the process of tumor development. We aim at exploring the functions of miRNA in neuroblastoma. PATIENTS AND METHODS Cell viability and invasion were evaluated by Cell Counting Kit-8 (CCK-8) and transwell assays. Western blot was utilized to assess the protein expression associated with epithelial-mesenchymal transition (EMT) markers. Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was performed to calculate the mRNA levels of miRNA and gene. RESULTS MiR-424 was downregulated while doublecortin like kinase 1 (DCLK1) was upregulated in neuroblastoma tissues and cells compared to adjacent non-tumor and normal spongiocyte cells. MiR-424 suppressed cell viability, invasion, and EMT by targeting DCLK1. MiR-424 regulated the expression of DCLK1 by directly binding to the 3'-untranslated region (UTR) of DCLK1 mRNA in SK-N-SH and Be2C cells. DCLK1 reversed partial functions of miR-424 in neuroblastoma. CONCLUSIONS MiR-424 suppressed cell viability, invasion, and EMT by directly targeting the 3'-UTR of DCLK1 mRNA. The newly identified miR-424/DCLK1 axis provides novel insights into the pathogenesis of neuroblastoma.

Abstract
The liver is an organ with regenerative capacity and is essential for maintaining the body homeostasis. Under pathological conditions, such as chronic hepatitis, liver cirrhosis and so on, the impairment of liver regeneration can lead to insufficient liver function or even liver failure. Therefore, promoting liver regeneration can improve the patient's prognosis. Prostaglandin E2 is a hormone-like messenger with physiological activity that can promote tissue regeneration. This article reviews the metabolism and transport pathways of prostaglandin E2 and its mechanism of action in liver tissue regeneration, and proposes that prostaglandin E2 is an important cytokine involved in the liver regeneration process, and has potential clinical application prospects for the treatment of liver injury.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM), body mass index (BMI) and gestational weight gain (GWG) are salient predictors of pregnancy-outcomes. However, findings on the association between GDM, BMI, and GWG with fetal growth measures are limited. OBJECTIVE The aim of this study was to investigate the effect of GDM on fetal growth measures and birth outcomes. METHODS All participants came from Tongji Maternal and Child health cohort, in which pregnant women were enrolled before 16 weeks of gestation and had their weights measured regularly during antenatal visits. GDM was diagnosed by oral glucose tolerance test (OGTT) during 24-28 weeks of gestation. Ultrasound measurements of fetal bi-parietal diameters (BPD), head circumferences (HC), abdominal circumferences (AC) and femur length (FL) before birth were collected and neonate outcomes were obtained from the hospital records. Odds ratios were calculated using logistic regression to assess the association of GDM, pre-pregnancy BMI, and GWG with fetal growth measures of ultrasound and birth outcomes, while controlling confounding. RESULTS Of 3253 singleton pregnant women, 293 (9.0%) were diagnosed with GDM, 357 (11.0%) were overweight before pregnancy, and 1995 (61.3%) had excessive GWG. GDM was associated with decreased intrauterine fetal growth measurements including BPD and AC. Maternal pre-pregnancy overweight was associated with increased fetal HC and neonatal birth weight and length, women gained excessive GWG had increased fetal growth measurements of BPD, HC, AC, FL, neonatal birth weight and length. Offspring of GDM women had increased odds of cesarean section 1.31 (1.03, 1.66) and preterm birth 2.02 (1.05, 3.91) in unadjusted models, but these associations disappeared after adjustment. Compared with neonate born to mothers with normal pre-pregnancy weight, those born to underweight mother had higher risk of SGA, and lower risk of cesarean section, LGA and macrosamia, whereas those born to overweight mother had increased risk of cesarean section, LGA and macrosamia. Compared with neonate born to mothers of adequate GWG, neonate of women with excessive GWG had elevated risk of cesarean section, LGA and macrosamia, but lower risk of preterm birth and SGA. CONCLUSION Pre-pregnancy BMI, GWG and GDM all associated with fetal growth and birth outcomes. The effect of GDM decreased after adjusting pre-pregnancy BMI and GWG. Early screening and management of GDM, preventing excessive GWG could help protect fetuses of GDM mothers from adverse birth outcomes.

Abstract
OBJECTIVE Information is limited regarding the possible relationship between diet-related inflammation and the risk of gestational diabetes mellitus (GDM). This study investigated the association between the inflammatory potential of the diet, measured by the dietary inflammatory index (DII), and GDM risk in pregnant Chinese women. METHODS This study included 2639 eligible women from the Tongji Maternal and Child Health Cohort. Dietary intake was assessed by a validated semiquantitative food frequency questionnaire and was used to calculate the DII score. The DII was then validated using C-reactive protein measurements in a subsample of 133 pregnant women. GDM diagnoses were collected from medical records based on the results of a 75 g oral glucose tolerance test at 24 to 28 wk gestation. Multivariable-adjusted logistic regression models were performed to estimate the odds ratios (ORs) for GDM risk by DII score, modeled continuously and in tertiles. RESULTS Of the 2639 participants, 13.1% were diagnosed with GDM. DII scores ranged from -4.45 to 3.15 and were positively associated with C-reactive protein (adjusted β : 1.28, 95% confidence interval [CI]: 0.16, 2.40; P trend = 0.023) when comparing DII tertile 3 (most pro-inflammatory) to tertile 1 (most anti-inflammatory). A significant and positive association was observed between DII scores and GDM risk (adjusted OR: 1.43; 95% CI: 1.05, 1.95; P trend = 0.022) comparing the highest versus lowest tertiles. The stratified analysis showed that this association was stronger in pregnant women who were overweight or obese before pregnancy (adjusted OR: 2.20; 95% CI: 1.03, 4.69). CONCLUSIONS These findings suggest that a higher DII score, corresponding to a more proinflammatory diet, is associated with a higher risk of GDM, particularly in pregnant women who were overweight or obese before pregnancy.

Abstract
1. This study explored the effects of Astragalus membranaceus polysaccharide (APS) on intestinal inflammatory damage of goslings infected with parvovirus ('gosling plague').2. A total of 90 healthy goslings were randomly divided into three groups; control, infected or APS treated, respectively. Goslings in the infection and APS treatment groups were inoculated with 0.3 ml allantoic fluid containing goose parvovirus (ELD50 = 1 × 103/0.3 ml) by intramuscular injection and the control group were injected with saline (0.3 ml) twice a day for 15 days.3. Blood serum and the jejunum were collected at 5, 10 and 15 days after the start of the experiment to detect the activities of SOD and GSH-Px, levels of MDA, sIgA, IL-1β, IL-6 and TNF-α, the mRNA expression of IL-1β, IL-6, LITAF, NF-κB, COX-2 and PGE2, pathological damage in the jejunum and serum IgG, IgM, C3, C4, IFN-γ levels.4. After APS treatment, SOD and GSH-Px activities increased, MDA content decreased; sIgA, IL-1β, IL-6 and TNF-α protein content, and IL-1β, IL-6, LITAF, NF-κB, COX-2 and PGE2 mRNA expression decreased in the jejunal tissue, serum IgG, IgM, C3, C4, IFN-γ significantly increased and pathological damage of jejunum significantly improved.5. In conclusion, APS reduced intestinal inflammatory damage in goslings infected with parvovirus by improving the immune and antioxidant functions of goslings.

Abstract
Objective: To assess the expanding needs on lipid-lowering treatment in patients with acute coronary syndrome (ACS) by applying newly issued definition of extreme high-risk, which is proposed by Chinese expert consensus on lipid management of extreme high-risk atherosclerotic cardiovascular disease (ASCVD) patients of Chinese Society of Cardiology (CSC). Methods: Data of this study was derived from the Improving Care for Cardiovascular Disease in China (CCC) project, which was a case-based nationwide registry study and launched as a collaborative initiative by the American Heart Association and the CSC. The project consecutively recruited ACS patients from158 tertiary hospitals and 82 second hospitals across China, and detailed clinical information of patients was collected. This study enrolled ACS inpatients in CCC project from November 2014 to July 2019. The proportion of extreme high-risk patients, their characteristics, mean LDL-C levels at admission, the gap between measured LDL-C level and the new target, and lipid-lowering therapy at discharge were assessed. Results: Among 104 516 ACS inpatients enrolled in this study, 75.1% (78 527/104 516) met the criteria of extreme high-risk and were expected to achieve the new LDL-C goal. Among patients at extreme high-risk, 21.2% (16 651/78 527) had multiple severe ASCVD events and 78.8% (61 876/78 527) had 1 severe ASCVD event and at least two high-risk factors. For the extreme high-risk patients, the mean level of LDL-C at admission was (2.8±1.0) mmol/L, prevalence of LDL-C ≥1.4 mmol/L was 93.4% (73 307/78 527) and the median gap between LDL-C level at admission and the target of 1.4 mmol/L was 1.3 (0.8, 2.0) mmol/L. If LDL-C could be further reduced to 50% of the admission level, we estimated that 55.6% (43 632/78 527) of the extreme high-risk patients would achieve the new LDL-C goal. Among 40 875 patients with information about discharge statin dosage, 93.5% (28 004/29 947) of the extreme high-risk patients were prescribed with statins at discharge, and among them 95.1% (26 632/28 004) received statin monotherapy and 91.1% (25 501/28 004) were at moderate doses of statins. Conclusion: About three fourth of inpatients with ACS were categorized as extreme high-risk based on the new definition of CSC expert consensuses, nine out of ten patients at extreme high-risk didn't achieve the new LDL-C target at admission, and the intensity of lipid-lowering therapy was insufficient in clinical practice. There are substantially expanding needs for implementing more intensive and effective lipid-lowering strategies.

Abstract
OBJECTIVE To clarify the potential function of miRNA-96 in accelerating the malignant progression of ovarian cancer (OC) and its underlying mechanism. PATIENTS AND METHODS The expression patterns of miRNA-96 in 36 matched OC tissues and adjacent normal tissues were determined by qRT-PCR. We analyzed the correlation between the miRNA-96 level and the clinical parameters of OC patients. Subsequently, the cellular levels of miRNA-96 in OC cell lines were determined as well. To construct miRNA-96 inhibitor and NC, the regulatory effects of miRNA-96 on the proliferative and migratory abilities in OC cells were examined. The target gene of miRNA-96 was verified by Dual-Luciferase Reporter Gene Assay. Finally, the rescue experiments were conducted to clarify the regulatory role of miRNA-96/FOXO3a axis in the malignant progression of OC. RESULTS MiRNA-96 was upregulated in OC tissues relative to adjacent normal ones. Compared with OC patients presenting high-level of miRNA-96, those with low-level miRNA-96 suffered more advanced tumor staging and a worse overall survival. The transfection of miRNA-96 inhibitor markedly attenuated proliferative and migratory abilities in SKOV3 and CAOV3 cells. In addition, FOXO3a was identified to be the target gene of miRNA-96, which was negatively regulated by miRNA-96. FOXO3a exerted a lower abundance in OC tissues relative to adjacent normal ones. Finally, the rescue experiments revealed that FOXO3a knockdown could abolish the inhibitory role of miRNA-96 knockdown in the proliferative, migratory, and invasive abilities in OC cells. CONCLUSIONS The knockdown of miRNA-96 attenuated the proliferative and migratory abilities in OC cells by targeting FOXO3a. We believed that miRNA-96 accelerates the malignant progression of OC, which could be utilized as a therapeutic target in clinical application.

Abstract
Investigators in previous studies have drawn inconsistent conclusions regarding the relationship between relatively low exposure to fine particulate matter (particulate matter with an aerodynamic diameter ≤2.5 μm (PM2.5)) and risk of gestational diabetes mellitus (GDM), while the association between high PM2.5 exposure and GDM risk has not been well studied. We investigated the association of high PM2.5 exposure during pregnancy with blood glucose levels and GDM risk in Chinese women. The present study was conducted from August 2013 to May 2016 among 3,967 pregnant women in the Tongji Maternal and Child Health Cohort in Wuhan, China. PM2.5 exposure during pregnancy for each participant was estimated by means of land-use regression models. An interquartile-range increase in PM2.5 exposure (33.84 μg/m3 for trimester 1 and 33.23 μg/m3 for trimester 2) was associated with 36% (95% confidence interval (CI): 1.15, 1.61) and 23% (95% CI: 1.01, 1.50) increased odds of GDM during trimester 1 and trimester 2, respectively. An interquartile-range increment of PM2.5 exposure during trimester 1 increased 1-hour and 2-hour blood glucose levels by 1.40% (95% CI: 0.42, 2.37) and 1.82% (95% CI: 0.98, 2.66), respectively. The same increment of PM2.5 exposure during trimester 2 increased fasting glucose level by 0.85% (95% CI: 0.41, 1.29). Our findings suggest that high PM2.5 exposure during pregnancy increases blood glucose levels and GDM risk in Chinese women.

Abstract
OBJECTIVE Colorectal cancer (CRC) is one of the leading causes of cancer-related deaths around the world. Recently, using the high-throughput techniques, long non-coding RNAs (lncRNAs) have been shown to play an important role in CRC progression. In the present study, we aimed to determine lncRNA DLX6 Antisense RNA 1 (DLX6-AS1) in CRC tissues and cell lines and to investigate the molecular mechanisms of DLX6-AS1 in CRC progression. PATIENTS AND METHODS Quantitative real-time PCR was performed to detect gene expression; cell counting kit-8, colony formation, cell invasion, and migration assays were performed to determine cell proliferation, invasion, and migration, respectively; caspase-3 activity assay kit was used to detect caspase-3 activity; in vivo tumor growth was evaluated in a nude mice xenograft model. RESULTS DLX6-AS1 was up-regulated in 60 CRC tissues when compared to normal adjacent colorectal tissues, and high expression of DLX6-AS1 was correlated with advanced T stage and distant metastasis in CRC patients. The up-regulation of DLX6-AS1 was further confirmed in CRC cell lines. The gain-of-function assays showed that DLX6-AS1 overexpression promoted HCT116 cell proliferation, invasion, and migration, but inhibited cell apoptosis; while the loss-of-function assays showed that DLX6-AS1 knockdown exerted the opposite effects in SW480 cells. In vivo studies revealed that DLX6-AS1 knockdown suppressed tumor growth in the nude mice xenograft model. In addition, DLX6-AS1 overexpression caused an increase in the phosphorylated phosphoinositide 3-kinase (p-PI3K), p-AKT and p-mammalian target of rapamycin (mTOR) protein levels, and DLX6-AS1 knockdown had the opposite effects. Blockade of PI3K/AKT/mTOR signalling pathway by using mTOR inhibitor partially abolished the enhanced effects of DLX6-AS1 overexpression on CRC cell proliferation and metastasis. CONCLUSIONS In summary, our data indicated that DLX6-AS1 promoted CRC cell proliferation, invasion, and migration but inhibited cell apoptosis via targeting PI3K/AKT/mTOR signalling pathway, suggesting the key role of DLX6-AS1 in CRC progression.

MATERNAL AND CHILD NUTRITION 2020; 17:e13043. [PMID: 32815668 PMCID: PMC7729649 DOI: 10.1111/mcn.13043] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/14/2019] [Revised: 04/07/2020] [Accepted: 05/21/2020] [Indexed: 11/30/2022]
Abstract
We aimed to assess protein nutrition status during pregnancy by maternal plasma total protein (MTP) levels in urban pregnant women and to explore the association between the trimester-specific MTP levels and risk of preterm birth (PTB). A prospective design was conducted in 3,382 mother-newborn pairs with the second-trimester maternal MTP information and in 3,478 mother-newborn pairs with the third-trimester MTP information. Multiple Cox proportional hazard regression and multiple linear regression were used to analyse the associations between MTP levels and PTB risk as well as gestational duration, respectively. Nearly all the second-trimester MTP levels were within the clinical reference range, but more than 40% of the third-trimester MTP levels were less than the lower limit of normal. No significant association was found between the second-trimester MTP level and PTB risk. However, the adjusted hazard ratios (HRs) of PTB across increasing quartiles of the third-trimester MTP levels were 1.00 (reference), 0.59 (0.36, 0.95), 0.35 (0.20, 0.60), and 0.32 (0.19, 0.53) (p for trend < 0.001), respectively. Each standard deviations increment of the third-trimester MTP was associated with increase of 0.13 weeks in gestational duration. Moreover, stratified analyses showed that the effects of third-trimester MTP on PTB risk and gestational duration were stronger in pregnant women carrying female offspring than those carrying male offspring (p for interaction < 0.05). The third-trimester MTP level was inversely associated with PTB risk and was positively associated with gestational duration. Improving third-trimester MTP level may be helpful for preventing PTB.

Abstract
OBJECTIVE Colorectal cancer (CRC) is one of the most frequent malignant tumors worldwide. Colon cancer and rectal cancer are two different malignant types, and it is important to distinguish these two cancers. However, the physiological function of microRNA-3174 (miR-3174) in rectal cancer remains unknown. Therefore, the aim of this study was to investigate the role of miR-3174 in rectal cancer progression and to explore the possible underlying mechanism. PATIENTS AND METHODS The relative expression level of miR-3174 in rectal cancer was evaluated by quantitative Real-time polymerase chain reaction (qRT-PCR). Cell counting kit-8 (CCK8) assay and colony formation assay were employed to detect the proliferation ability of cells. Flow cytometric analysis was used to detect cell cycle distribution and apoptotic cells. Bioinformatics analysis and dual luciferase reporter gene assay were employed to predict and verify the target genes of miR-3174, respectively. Meanwhile, the protein expression level of pterin-4 alpha-carbinolamine dehydratase 2 (PCBD2) normalized to glyceraldehyde 3-phosphate dehydrogenase (GAPDH) was assessed by Western blotting. RESULTS The expression level of miR-3174 was significantly up-regulated in rectal cancer. CCK8 assay and colony formation assay suggested that miR-3174 markedly promoted the proliferation of rectal cancer cells. Subsequently, flow cytometric analysis demonstrated that over-expressed miR-3174 significantly accelerated cell cycle, whereas remarkably inhibited cell apoptosis. Public prediction websites and dual luciferase reporter gene assay further validated that PCBD2 was a direct down-stream target of miR-3174. Moreover, rescue assay confirmed that miR-3174 functioned as an oncogene in rectal cancer by regulating PCBD2. CONCLUSIONS Our study elucidated that miR-3174 functioned as an oncogene in rectal cancer by targeting PCBD2, which might bring new insights into the search for novel biomarkers and therapeutic strategies.

Abstract
PURPOSE To assess the longitudinal associations between maternal total bile acid (TBA) levels during early mid-pregnancy and the subsequent risk of gestational diabetes mellitus (GDM). METHODS In a prospective cohort study, pregnant women who were enrolled prior to gestational week 16 were followed until delivery. TBA levels were tested during weeks 14-18 of gestation. Using logistic regression, we analyzed the associations between quartiles of TBA and GDM based on a 75-g oral glucose tolerance test (OGTT) at 24-28 gestational weeks. RESULTS The GDM rate was 7.9% (114/1441). The mean TBA level was higher in women with GDM than in those without GDM (2.1 ± 2.0 vs 1.5 ± 1.0 µmol/L, P = 0.000). The highest TBA level quartile (2.1-10.7 µmol/L) had a 1.78-fold (95% CI 1.01, 3.14) increased risk of GDM compared with that of the lowest quartile (0.0-0.8 µmol/L) after adjusting for pre-pregnancy body mass index (BMI), gestational, age at TBA test and other confounders. High TBA levels were involved in the fasting glucose level rather than that at 1 h and 2 h after OGTT in all participants. CONCLUSIONS Pregnant women with higher serum TBA levels during early mid-pregnancy have a higher risk of developing GDM. TBA may be a new risk factor for GDM.

Abstract
Abstract Objective To explore the impulse control and event-related potential (ERP) characteristics of patients with mental disorders caused by traumatic brain injury (TBI) in forensic psychiatry identification and to provide objective auxiliary indicators for forensic psychiatry identification. Methods Thirty patients (TBI group) with mental disorders caused by traumatic brain injury, who were identified as mild psychiatric impairment by judicial psychiatry, including 24 males and 6 females, as well as the thirty people in the control group participated in the study. All the participants completed Barratt Impulsiveness Scale-11 (BIS-11) and ERP induced by Go/NoGo tasks. BIS-11 and ERP data were collected and analyzed. Results The results of the BIS-11 showed that the total score and subscale scores of the TBI group were higher compared to the control group (P<0.05). Moreover, the TBI group exhibited significantly lower NoGo-N2 amplitude and lower NoGo-P3 amplitude than the control group. The NoGo-N2 amplitude was larger than the Go-N2 amplitude, and the NoGo-P3 amplitude was larger than the Go-P3 amplitude in both groups (P<0.05). Conclusion Traumatic brain injury could impair impulse control of mild psychiatric impairment patients, and the amplitudes of NoGo-N2 and NoGo-P3 could be important parameters to evaluate the impulse control of patients with mental disorders caused by traumatic brain injury.

Abstract
Current results regarding the effect of folic acid (FA) supplement use on gestational hypertension (GH) and preeclampsia are limited and inconsistent. We aimed to investigate whether FA supplement use was associated with GH and preeclampsia. Participants from the Tongji Maternal and Child Health Cohort with information on periconceptional FA supplement use and diagnosis of GH/preeclampsia were included (n=4853). Robust Poisson regression was used to assess the association of FA supplement use and GH and preeclampsia. Among the 4853 participants in this study, 1161 (23.9%) and 161 (3.3%) women were diagnosed with GH and preeclampsia, respectively. The risk ratio of developing GH was higher in women who used ≥800 µg/d FA supplement from prepregnancy through midpregnancy than nonusers (risk ratio, 1.33 [1.08–1.65]). After adjusting for social-demographic, reproductive, lifestyle factors, family history of hypertension, other supplement use, and gestational weight gain, the adverse association remained significant (risk ratio, 1.32 [1.06–1.64]). Restricting the analysis among women with normal weight, without family history of hypertension, and without gestational diabetes mellitus, the positive FA-GH association still existed. We did not find any significant association between FA supplement use and preeclampsia regardless of adjustment. High-dose (≥800 µg/d) FA supplement use from prepregnancy through midpregnancy was associated with increased risk of GH. Attention should be given to avoid the potential risk of GH due to inappropriate FA supplement use in women who are planning or capable of pregnancy.
