Self-Esteem Moderates the Effect of Compromising Thinking on Forgiveness Among Chinese Early Adolescents

Forgiveness contributes to positive social relationships, which is critical for individual development, particularly for early adolescents. Most previous studies focused on the unique roles of cognitive factors (e.g., compromising thinking) and personality traits (e.g., self-esteem) in the process of developing forgiveness. However, sporadic research has examined their interactive effect on forgiveness from an integrated perspective. Given that forgiveness has been categorized into decisional and emotional forgiveness, this study aimed to examine the effects of compromising thinking on two types of forgiveness, and the moderating effects of self-esteem on the association between compromising thinking and forgiveness among early adolescents. A total of 1,009 Chinese primary and secondary school students (50.4% males; M_age = 11.75, SD = 1.27) were recruited to complete three self-reported questionnaires. The results showed that compromising thinking predicted decisional forgiveness but not emotional forgiveness. Furthermore, self-esteem was identified to moderate the conditional effects of compromising thinking on decisional and emotional forgiveness. These findings advance a better understanding of the construct and mechanism of forgiveness, which can provide insights for targeted forgiveness interventions among early adolescents, such as compromising thinking instructions and self-esteem enhancement programs.

Genome-wide Identification of Foxf2 Target Genes in Palate Development

Cleft palate is among the most common structural birth defects in humans. Previous studies have shown that mutations in FOXF2 are associated with cleft palate in humans and mice and that Foxf2 acts in a Shh-Foxf-Fgf18-Shh molecular network controlling palatal shelf growth. In this study, we combined RNA-seq and ChIP-seq approaches to identify direct transcriptional target genes mediating Foxf2 function in palate development in mice. Of 155 genes that exhibited Foxf2-dependent expression in the developing palatal mesenchyme, 88 contained or were located next to Foxf2-binding sites. Through in situ hybridization analyses, we demonstrate that expression of many of these target genes, including multiple genes encoding transcription factors and several encoding extracellular matrix-modifying proteins, were specifically upregulated in the posterior region of palatal shelves in Foxf2^-/- mouse embryos. Foxf2 occupancy at many of these putative target loci, including Fgf18, in the developing palatal tissues was verified by ChIP-polymerase chain reaction analyses. One of the Foxf2 target genes, Chst2, encodes a carbohydrate sulfotransferase integral to glycosaminoglycan sulfation. Correlating with ectopic Chst2 expression, Foxf2^-/- embryos a exhibited region-specific increase in sulfated keratan sulfate and a concomitant reduction in chondroitin sulfate accumulation in the posterior palatal mesenchyme. However, expression of the core protein of versican, a major chondroitin sulfate proteoglycan important in palatal shelf morphogenesis, was increased, whereas expression of collagen I was reduced in the corresponding region of the palatal mesenchyme. These results indicate that, in addition to regulating palatal shelf growth through the Fgf18-Shh signaling network, Foxf2 controls palatal shelf morphogenesis through regulating expression of multiple transcription factors as well as through directly controlling the synthesis and processing of extracellular matrix components in the palatal mesenchyme. Our ChIP-seq and RNA-seq data sets provide an excellent resource for comprehensive understanding of the molecular network controlling palate development.

LINC01116 promotes the proliferation and inhibits the apoptosis of gastric cancer cells

OBJECTIVE

To detect the relative expression of long intergenic non-protein coding ribonucleic acid (LINC) 01116 in gastric cancer (GC) tissues and cells and analyze the correlations of LINC01116 expression with the clinicopathologic characteristics of patients and investigate the biological functions of LINC01116 via in vitro experiments.

PATIENTS AND METHODS

The quantitative Real Time Fluorescence-Polymerase Chain Reaction (qRT-PCR) was applied to detect the relative expression level of LINC01116 in 73 cases of tissues and cells in GC patients. The patients were divided into LINC01116 high expression group and LINC01116 low expression group, and the correlations of LINC01116 with patient's pathological characteristics were statistically analyzed. In vitro experiments [cell counting kit-8 (CCK-8) assay, colony formation assay, and flow cytometry] were adopted to investigate the influences of LINC01116 on the biological functions of GC cells.

RESULTS

According to the results of qRT-PCR, the expression of LINC01116 was upregulated in 54 out of 73 cases of tissues (fold change >1), and it was upregulated in GC cells compared with that in the normal gastric mucosal epithelial cells (GES-1). The statistical analysis manifested that the highly expressed LINC01116 was positively correlated with the tumor-node-metastasis (TNM) stage (p=0.008), lymph node metastasis (p=0.005), and depth of invasion (p=0.007) of the GC patients. The patients with high expression of LINC01116 in the GC tissues had a shorter survival time than those with low expression (p=0.017). After interference in the expression of LINC01116, it was shown in CCK-8 assay and colony formation assay that the proliferative capacity of the cells was decreased. The results of flow cytometry indicated that the cell cycle was arrested at the G1/G0 phase, and the apoptosis rate was increased.

CONCLUSIONS

LINC01116 is highly expressed in GC tissues and cells, and highly expressed LINC01116 indicates poor prognosis of the patients, promotes the proliferation, and inhibits the apoptosis of GC cells.

Rapid Identification of Four New Synthetic Cannabinoids in Whole Blood

Objective To establish accurate and rapid methods to identify four new synthetic cannabinoids （JWH-203, JWH-122, 5F-APINACA and AB-CHMINACA） in blood samples. Methods The whole blood samples were extracted by acetonitrile and methanol, screened by gas chromatography-mass spectrometry （GC-MS） then confirmed by liquid chromatography-tandem mass spectrometry （LC-MS/MS） method, and multiple reaction monitoring （MRM） mode was used for quantitative analysis. Results The GC-MS method needed 21 min to complete the analysis, while the LC-MS/MS method needed 5 min. The AB-CHMINACA, JWH-203, 5F-APINACA and JWH-122 all used quasi molecular ion peak as a parent ion. The precursor-product ion combinations were m/z 357.4→312.2, m/z 340.2→125.0, m/z 384.1→135.1 and m/z 356.4→169.2. The four synthetic cannabinoids in blood samples had good linearity in the 1-250 ng/mL mass concentration range （r>0.99）. The limits of detection （LODs） were in the range of 0.1-0.5 ng/mL, the recovery rate was 85.4%-95.2%, the RSD less than 10.0%, and the matrix effect was 80.3%-92.8%. Conclusion The GC-MS and LC-MS/MS chromatographic behaviors and mass spectrometry analysis information of four synthetic cannabinoids were obtained in this study, and the possible causes of differences in chromatographic behaviors were discussed preliminarily. Therefore this study has a suggestive effect on judging the development trend of synthetic cannabinoids. This method can be used for rapid identification of four synthetic cannabinoids in blood, which can provide reference for identification of new synthetic cannabinoids when they are proliferating at present.

Association of Depression and Unhealthy Lifestyle Behaviors in Chinese Patients With Acute Coronary Syndromes

PURPOSE

This study sought to examine associations between depression and unhealthy lifestyle behaviors in Chinese patients with acute coronary syndromes (ACS).

METHODS

This cross-sectional study included 4043 ACS patients from 16 hospitals across China who participated in the I-Care (Integrating Depression Care in Acute Coronary Syndromes Patients) trial. Patients were enrolled between November 2014 and January 2017. Depression was assessed with the Patient Health Questionnaire-9 (PHQ-9). Five lifestyle behaviors were assessed: smoking, drinking, body mass index (BMI), physical activity, and sleep quality.

RESULTS

A total of 135 patients (3.3%) were considered clinically depressed (PHQ-9 ≥10). After adjusting for covariates, physical activity and sleep quality were inversely related to PHQ-9 scores. Adjusted logistic models showed that depressed patients were 1.7 times likely to be physically inactive (OR = 1.74; 95% CI, 1.15-2.64) and 4.6 times likely to have poor sleep quality (OR = 4.60; 95% CI, 3.07-6.88) compared with nondepressed patients. The association of depression with smoking, unhealthy drinking, and unhealthy BMI was not significant after adjustment for demographic characteristics. Higher depression scores were found to be associated with a greater number of unhealthy lifestyle behaviors (P for trend < .001).

CONCLUSIONS

The association of depression and unhealthy lifestyles in post-ACS patients suggests that reducing depressive symptoms and improving healthy lifestyle behaviors could potentially improve clinical outcomes in this vulnerable patient population.

Requirement of Hyaluronan Synthase-2 in Craniofacial and Palate Development

Cleft palate is a common major birth defect resulting from disruption of palatal shelf growth, elevation, or fusion during fetal palatogenesis. Whereas the molecular mechanism controlling palatal shelf elevation is not well understood, a prevailing hypothesis is that region-specific accumulation of hyaluronan, a predominant extracellular glycosaminoglycan in developing palatal mesenchyme, plays a major role in palatal shelf elevation. However, direct genetic evidence for a requirement of hyaluronan in palate development is still lacking. In this study, we show that Has2, 1 of 3 hyaluronan synthases in mammals, plays a major role in hyaluronan synthesis in the neural crest-derived craniofacial mesenchyme during palatogenesis in mice. We analyzed developmental defects caused by tissue-specific inactivation of Has2 throughout the cranial neural crest lineage or specifically in developing palatal or mandibular mesenchyme, respectively, using Wnt1-Cre, Osr2-Cre, and Hand2-Cre transgenic mice. Inactivation of Has2 either throughout the neural crest lineage or specifically in the developing palatal mesenchyme caused reduced palatal shelf size and increased palatal mesenchyme cell density prior to the time of normal palatal shelf elevation. Whereas both Has2f/f;Wnt1-Cre and Has2f/f;Osr2-Cre mutant mice exhibit cleft palate at complete penetrance, the Has2f/f; Wnt1-Cre fetuses showed dramatically reduced mandible size and complete failure of palatal shelf elevation, whereas Has2f/f;Osr2-Cre fetuses had normal mandibles and delayed palatal shelf elevation. All Has2f/f;Hand2-Cre pups showed reduced mandible size and about 50% of them had cleft palate with disruption of palatal shelf elevation. Results from explant culture assays indicate that disruption of palatal shelf elevation in Has2f/f;Hand2-Cre mutant fetuses resulted from physical obstruction by the malformed mandible and tongue. Together, these data indicate that hyaluronan plays a crucial intrinsic role in palatal shelf expansion and timely reorientation to the horizontal position above the tongue as well as an important role in mandibular morphogenesis that secondarily affects palatal shelf elevation.

P3623Integrating depression and acute coronary syndrome care in low-resource hospitals in china: primary results from the I-Care randomised clinical trial

Background

Depression and acute coronary syndromes (ACS) are significant public health challenges. Patients with ACS often experience depression, which adversely affects prognosis. Low-cost, sustainable, and effective service models that integrate depression care into the management of ACS patients to reduce depression and improve ACS outcomes are critically needed.

Purpose

I-CARE study is a multi-center, randomised clinical trial (RCT) to evaluate the efficacy of an 11-month integrated care (IC) intervention compared to usual care (UC) in the management of ACS patients.

Methods

The I-CARE RCT was conducted between October 2014 and March 2018 in 16 rural Chinese hospitals. A total of 4041 patients with ACS were consecutively enrolled and randomly assigned in a 1:1 ratio to an IC intervention consisting of nurse-led risk factor management, group-based counseling supplemented by individual problem solving therapy and antidepressant medications as needed, or UC. The primary outcome was change in Patient Health Questionnaire-9 (PHQ-9) scores from baseline to 6 and 12 months. Secondary outcomes included incidence of major adverse events (MAEs) after discharge, quality of life (EQ5D), and adherence to ACS secondary prevention medications. Data analysis used a multilevel mixed-effects model with hospital-level and subject-level random-effect intercepts and hospital-level random slope incorporated to adjust for clustering effect. Primary analyses followed the intent-to-treat principle.

Results

The mean age of the patients was 61±10 years and 63% were men; however, only 3.3% were classified as depressed based upon a cutoff of ≥10 on the PHQ-9, and 26.9% had PHQ-9 scores between 5 to 9 at the baseline. There were no significant differences in patients' clinical characteristics between IC and UC groups. Changes in PHQ-9 scores from baseline to 6- and 12-months did not differ between treatment groups (−1.47 in IC group vs −1.40 in UC group; adjusted mean difference, −0.04; 95% CI, −0.17 to 0.08 at 6-months; −1.62 in IC group vs −1.54 in UC group; adjusted mean difference, −0.06; 95% CI: −0.19 to 0.06 at 12-months).The risk of MAEs after discharge between IC and UC groups also did not differ significantly (42.1% vs 43.1%; p=0.307).

Conclusions

Results from the I-CARE trial showed that a nurse-coordinated ACS and depression IC intervention did not reduce depression or improve clinical outcomes among patients with ACS compared to usual care controls. The low prevalence of depression was unexpected and may have minimized the potential added benefits of the IC intervention on depression and clinical outcomes compared to UC.

A novel 86-bp indel of the motilin receptor gene is significantly associated with growth and carcass traits in Gushi-Anka F2 reciprocal cross chickens

1. A previous whole-genome association analysis has identified the motilin receptor gene (MLNR), which regulates gastrointestinal motility and gastric emptying, as a candidate gene related to chicken growth.2. MLNR mRNA was expressed in all tissues tested, and the expression level in digestive tissues was greater than in other tissues. Expression levels in the pancreas, duodenum and glandular stomach at day old and one, two and three weeks of age indicated a possible correlation with the digestive system. This suggested that the MLNR gene plays a central role in gastrointestinal tract function and affects the growth and development of chickens. Moreover, there was a significant difference in expression in the glandular stomach tissue between Ross 308 and Gushi chickens at six weeks of age.3. Re-sequencing revealed an 86-bp insertion/deletion polymorphism in the downstream region of the MLNR gene. The mutation locus was genotyped in 2,261 individuals from nine different chicken breeds. MLNR expression levels in the glandular stomach of chickens with DD genotypes were greater than those in chickens with the ID and II genotypes. The DD genotype was the most dominant genotype in commercial broiler's (Ross 308 and Arbor Acres broilers), and the D allele frequency in these breeds exceeded 91%. The deletion mutation tended towards fixation in commercial broilers.4. Association with growth and carcass traits analysed in a Gushi-Anka F₂ intercrossed population, showed that the DD genotype was significantly associated with the greatest growth and carcass trait values, whereas values associated with the II genotype were the lowest in the F₂ reciprocal cross chickens.5. The results suggest that the mutation is strongly associated with growth related traits and it is likely to be useful for marker-assisted selection of chickens.

Genetic parameters of the thick-to-thin albumen ratio and egg compositional traits in layer-type chickens

1. Generating a robust egg albumen is one of the major factors contributing to interior egg quality owing to its nutritive value and superior appearance. However, the genetic factors regulating the proportion of thick albumen are poorly understood. 2. In this study, 1330 eggs were collected from 450 Rhode Island White layers, aged 40 weeks, to measure egg compositional traits for three successive days. The restricted maximum likelihood method was applied to estimate genetic parameters for the thick-to-thin albumen ratio and other egg compositional traits. A univariate animal model was fitted to calculate heritability for each trait. 3. The heritabilities of egg weight, yolk weight, albumen height, Haugh units, percentages of yolk, thick albumen, thin albumen and the thick-to-thin albumen ratio were 0.32, 0.34, 0.28, 0.47, 0.61, 0.39, 0.31, and 0.45, respectively. The percentage of thick albumen was negatively correlated genetically with all traits, and percentage of thin albumen was negatively correlated genetically with all traits except for Haugh units. The thick-to-thin albumen ratio was positively correlated genetically with egg weight, albumen height and Haugh units, with correlations ranging from 0.21 to 0.54. 4. The results indicated that the percentage of thick albumen and the thick-to-thin albumen ratio were found to be moderately to highly heritable, and selection for the thick-to-thin albumen ratio could be conducive to the improvement of egg albumen quality.

Inhibiting intuitive rules in a geometry comparison task: Do age level and math achievement matter?

Many people apply the "larger area-larger perimeter" rule to solve the perimeter comparison problems, even in situations where this intuitive rule is misleading. To investigate whether inhibitory control is needed in the perimeter comparison reasoning and whether the efficiency of inhibitory control varies with students' ages and achievements, we designed a negative priming paradigm and conducted two experiments. In Experiment 1, a negative priming effect was observed in both Chinese primary school students (n = 123) and college students (n = 42) when they were solving a perimeter comparison task. In Experiment 2 (N = 86), we found that the negative priming effect existed in both high-achieving and low-achieving primary school students, but the magnitude of this effect appeared to be smaller in high-achieving students. These results imply that success in solving geometry quantitative problems requires the ability to inhibit the larger area-larger perimeter intuition in some situations and also that high-achieving students are more capable of doing so.

Two insertion/deletion variants in the promoter region of the QPCTL gene are significantly associated with body weight and carcass traits in chickens

Glutaminyl-peptide cyclotransferase-like (QPCTL) is an isoenzyme of glutaminyl-peptide cyclotransferase (QPCT). QPCTL and QPCT catalyze the formation of N-terminal modified pyroglutamate-fractalkine and the chemokine CCL2. The objective of this study was to investigate the association between insertions/deletions in the chicken QPCTL promoter region with growth traits in chickens. We first detected two insertion/deletion variants of QPCTL via whole-genome resequencing analysis of DNA samples from Xichuan chickens. A total of 1896 individuals from 12 breeds were genotyped for 52- and 224-bp insertions/deletions. We found two novel insertions/deletions in the promoter region of the chicken QPCTL gene and studied their association with chicken body weight and carcass traits. Our findings show that QPCTL can be a molecular marker for chicken genetics and breeding programs.

Crucial and Overlapping Roles of Six1 and Six2 in Craniofacial Development

SIX1 and SIX2 encode closely related transcription factors of which disruptions have been associated with distinct craniofacial syndromes, with mutations in SIX1 associated with branchiootic syndrome 3 (BOS3) and heterozygous deletions of SIX2 associated with frontonasal dysplasia defects. Whereas mice deficient in Six1 recapitulated most of the developmental defects associated with BOS3, mice lacking Six2 function had no obvious frontonasal defects. We show that Six1 and Six2 exhibit partly overlapping patterns of expression in the developing mouse embryonic frontonasal, maxillary, and mandibular processes. We found that Six1 ^-/- Six2 ^-/- double-mutant mice were born with severe craniofacial deformity not seen in the Six1 ^-/- or Six2 ^-/- single mutants, including skull bone agenesis, midline facial cleft, and syngnathia. Moreover, whereas Six1 ^-/- mice exhibited partial transformation of maxillary zygomatic bone into a mandibular condyle-like structure, Six1 ^-/-Six2 ^+/- mice exhibit significantly increased penetrance of the maxillary malformation. In addition to ectopic Dlx5 expression at the maxillary-mandibular junction as recently reported in E10.5 Six1 ^-/- embryos, the E10.5 Six1 ^-/- Six2 ^+/- embryos showed ectopic expression of Bmp4, Msx1, and Msx2 messenger RNAs in the maxillary-mandibular junction. Genetically inactivating 1 allele of either Ednra or Bmp4 significantly reduced the penetrance of maxillary malformation in both Six1 ^-/- and Six1 ^-/- Six2 ^+/- embryos, indicating that Six1 and Six2 regulate both endothelin and bone morphogenetic protein-4 signaling pathways to pattern the facial structures. Furthermore, we show that neural crest-specific inactivation of Six1 in Six2 ^-/- embryos resulted in midline facial cleft and frontal bone agenesis. We show that Six1 ^-/- Six2 ^-/- embryos exhibit significantly reduced expression of key frontonasal development genes Alx1 and Alx3 as well as increased apoptosis in the developing frontonasal mesenchyme. Together, these results indicate that Six1 and Six2 function partly redundantly to control multiple craniofacial developmental processes and play a crucial neural crest cell-autonomous role in frontonasal morphogenesis.

[Peripheral small airway dysfunction differences between idiopathic pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension]

Objective: To investigate the peripheral small airway dysfunction differences between idiopathic pulmonary arterial hypertension (IPAH) and chronic thromboembolic pulmonary hypertension (CTEPH). Methods: Impulse oscillmetory system testing (IOS) and pulmonary function testing (PFT) were performed in IPAH and CTEPH patients and 30 healthy control group. We also carried out a subgroup analysis depending on their medical history of airway diseases. Results: We included 42 IPAH and 47 CTEPH patients (with or without airways disease: 8 vs. 34 and 17 vs. 34, respectively). Compared with CTEPH patients, IPAH patients were younger but had more serious pulmonary vessel resistance and mean pulmonary arterial resistance. Compared with IPAH patients, CTEPH patients had significant impaired peripheral small airway dysfunction with decreased of MEF(50) (% pred), MMEF(75/25) evaluated by PFT and R5-R20, Δ R5-R20 and AX measured by IOS [10.6(2.0, 33.0) vs. 2.5(-5.0, 16.5); 22.1(14.0, 32.6) vs. 15.5 (7.0, 23.2); 7.64(4, 18.6) vs. 6(3, 11) respectively, all P<0.05]. Subgroup analysis revealed there were no significant peripheral small dysfunction differences in IPAH patients with or without airway diseases. CTEPH patients had a higher proportion of airway diseases and more serious peripheral dysfunction than IPAH patients with airway diseases. Compared with control healthy group, peripheral airway dysfunction was more obvious even in IPAH and CTEPH patients without airway diseases. Conclusion: Compared with IPAH, CTEPH patients were older, but had better hemodynamics and a higher proportion of airway diseases. The peripheral airway dysfunction were more serious in CTEPH patients without airway diseases than IPAH patients without airway diseases and healthy controls group.

A diffusion-based approach for modelling crack tip behaviour under fatigue-oxidation conditions

Modelling of crack tip behaviour was carried out for a nickel-based superalloy subjected to high temperature fatigue in a vacuum and air. In a vacuum, crack growth was entirely due to mechanical deformation and thus it was sufficient to use accumulated plastic strain as a criterion. To study the strong effect of oxidation in air, a diffusion-based approach was applied to investigate the full interaction between fatigue and oxygen penetration at a crack tip. Penetration of oxygen into the crack tip induced a local compressive stress due to dilatation effect. An increase in stress intensity factor range or dwell times imposed at peak loads resulted in enhanced accumulation of oxygen at the crack tip. A crack growth criterion based on accumulated levels of oxygen and plastic strain at the crack tip was subsequently developed to predict the crack growth rate under fatigue-oxidation conditions. The predicted crack-growth behaviour compared well with experimental results.
