Abstract
Disrupted sleep has a profound adverse impact on lives of Parkinson's disease (PD) patients and their caregivers. Sleep disturbances are exceedingly common in PD, with substantial heterogeneity in type, timing, and severity. Among the most common sleep-related symptoms reported by PD patients are insomnia, excessive daytime sleepiness, and sleep fragmentation, characterized by interruptions and decreased continuity of sleep. Alterations in brain wave activity, as measured on the electroencephalogram (EEG), also occur in PD, with changes in the pattern and relative contributions of different frequency bands of the EEG spectrum to overall EEG activity in different vigilance states consistently observed. The mechanisms underlying these PD-associated sleep-wake abnormalities are poorly understood, and they are ineffectively treated by conventional PD therapies. To help fill this gap in knowledge, a new progressive model of PD - the MCI-Park mouse - was studied. Near the transition to the parkinsonian state, these mice exhibited significantly altered sleep-wake regulation, including increased wakefulness, decreased non-rapid eye movement (NREM) sleep, increased sleep fragmentation, reduced rapid eye movement (REM) sleep, and altered EEG activity patterns. These sleep-wake abnormalities resemble those identified in PD patients. Thus, this model may help elucidate the circuit mechanisms underlying sleep disruption in PD and identify targets for novel therapeutic approaches.

Abstract
The positive association between meaning in life (MIL) and mindfulness has been supported; however, previous research has been limited to the trait level. To explore the dynamics of mindfulness and MIL in the state level, the present study used the experience sampling method (ESM) and conducted a dynamic structural equation model (DSEM). In addition, we examined the moderation of baseline depression in this dynamic relationship and the protective role of the dynamics on depression. We recruited 184 college students (Mage = 21.58, 33.15% male), who reported three times a day for 14 consecutive days, and analyzed the 7726 collected responses. Firstly, a virtuous cycle between mindfulness and MIL was proven. Besides, the baseline depressive symptoms moderated the predictive of mindfulness on MIL, suggesting state mindfulness gave people with more depressive symptoms more meaningful in daily life. Lastly, the result also demonstrated the positive prediction of mindfulness on MIL and alleviated the worsening of depressive symptoms within 2 weeks. The findings extended the relationship between MIL and mindfulness from trait level to state level, enriching the self-determination theory, and examined the unique effect of depressive symptoms in the dynamics.

Abstract
Children are more likely to develop depressive symptoms in families where parents have depressive symptoms. By conceptualizing the individual depressive symptom network of each family member as a whole, this study proposes a family symptom network model, and explored the mechanisms of transmission of depression within nuclear families at the symptom level. This study used four waves (2012, 2016, 2018, 2020) of data from the China Family Panel Studies (CFPS), which in wave one contained a representative sample of 1963 children (1038 boys; age = 12.60), 4763 mothers and 4614 fathers from China. Children with their parents completed the Center for Epidemiology Studies Depression Scale at each wave. Individual depressive symptom networks among children, fathers, and mothers were highly similar and stable across time. When considering depressive symptoms of all family members as a whole, there was a wide range of associations between child, father, and mother depressive symptom networks. The results of the cross-lagged network model suggest the bidirectional relationships between couples and parent-child depression. The current study provides preliminary validation of the family symptom network model. The model represents a further integration and extension of network theory of mental disorders and family systems theory, and points out the limitations of studying the intergenerational transmission of depression from a latent variable perspective. Thus, the family symptom network model proposed in this study could provide valuable new insights into understanding the intergenerational transmission of depression.

Abstract
Research has suggested that daily cognitive reappraisal and mindfulness are differentially associated with emotional experience. Nevertheless, the different relationship between these two emotion regulation strategies and emotional experience remains unexplored amidst the COVID-19 pandemic, when people were facing unprecedented challenges and disruptions in their everyday lives. The current study aimed to examine the potential unidirectional or bidirectional relations between two strategies and daily emotional experience during the COVID-19 pandemic and whether the associations between the two strategies and emotional experience varied. A total of 184 college students participated in this study. Daily positive reappraisal, mindful attention and awareness (MAA), positive and negative affect, and COVID-19-related stress were assessed utilizing experience sampling method (three times a day for 14 consecutive days). Results suggested that the directionality of the link between the two strategies and daily emotional experience differed. The links between positive reappraisal and positive affect, negative affect, and COVID-19-related stress were transactional. However, a unidirectional relation was observed between positive affect and subsequent MAA. The study provided support for the contextual perspective of emotion regulation by demonstrating that the efficacy of regulation strategies is contingent upon the context. The identification of optimal conditions for effective strategies remains a crucial area for future research.

Abstract
PURPOSE To evaluate the genotypic and phenotypic relationship in a large cohort of OI patients and to compare the differences between eastern and western OI cohorts. METHODS A total of 671 OI patients were included. Pathogenic mutations were identified, phenotypic information was collected, and relationships between genotypes and phenotypes were analyzed. Literature about western OI cohorts was searched, and differences were compared between eastern and western OI cohorts. RESULTS A total of 560 OI patients were identified as carrying OI pathogenic mutations, and the positive detection rate of disease-causing gene mutations was 83.5%. Mutations in 15 OI candidate genes were identified, with COL1A1 (n = 308, 55%) and COL1A2 (n = 164, 29%) being the most common mutations, and SERPINF1 and WNT1 being the most common biallelic variants. Of the 414 probands, 48.8, 16.9, 29.2 and 5.1% had OI types I, III, IV and V, respectively. Peripheral fracture was the most common phenotype (96.6%), and femurs (34.7%) were most commonly affected. Vertebral compression fracture was observed in 43.5% of OI patients. Biallelic or COL1A2 mutation led to more bone deformities and poorer mobility than COL1A1 mutation (all P < 0.05). Glycine substitution of COL1A1 or COL1A2 or biallelic variants led to more severe phenotypes than haploinsufficiency of collagen type I α chains, which induced the mildest phenotypes. Although the gene mutation spectrum varied among countries, the fracture incidence was similar between eastern and western OI cohorts. CONCLUSION The findings are valuable for accurate diagnosis and treatment of OI, mechanism exploration and prognosis judgment. Genetic profiles of OI may vary among races, but the mechanism needs to be explored.

Abstract
AIM To evaluate whether abnormalities in white matter (WM) integrity are present in young children with epilepsy. MATERIALS AND METHODS Twelve children (3-6 years old) with epilepsy and six matched healthy controls were recruited for brain diffusion tensor imaging (DTI). Track-based spatial statistics (TBSS) was used to analyse and compare DTI indices of mean diffusivity (MD), fractional anisotropy (FA), axial and radial diffusivity (AD/RD) between patients and controls, and correlations between clinical variables and DTI parameters were analysed. RESULTS Compared with controls, patients showed increased FA in the left superior corona radiata and increased AD in the bilateral superior corona radiata. In children with generalised epilepsy, FA was increased in the left external capsule, while AD was decreased in the body of the corpus callosum, the left external capsule and the left superior longitudinal fasciculus. In those with focal epilepsy, FA was increased in the genu and body of the corpus callosum, and RD was decreased in the genu of the corpus callosum and left external capsule. Compared with partial epilepsy, generalised epilepsy was associated with increased FA in the right anterior corona radiata and decreased RD in the right anterior corona radiata and the genu and body of the corpus callosum. No significant correlations were observed between clinical variables and DTI parameters. CONCLUSIONS The results of this study indicate that the microstructure of the white matter is disturbed by epileptic discharges and a compensatory response occurs during early brain development.

Abstract
Oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) are two of the most common childhood mental disorders, and they have substantial comorbidity. The developmental precursor model has long been widely used to explain the mechanisms of comorbidity between ODD and ADHD, however whether it is equally effective at the symptomatic level is unclear. Therefore, this study aimed to (a) examine the stability of the ODD and ADHD comorbidity network in a longitudinal sample of high-risk children in China; and (b) examine the longitudinal relationship between the ODD and ADHD symptom networks based on a developmental precursor model. Two hundred sixty-three Chinese children aged 6 to 13 years with ODD and/or ADHD were assessed for symptoms of ODD and ADHD in two surveys conducted 1 year apart. We used data from these two time points to construct two cross-sectional networks and a cross-lagged panel network (CLPN) to explore the symptom network for comorbidity of ODD and ADHD. The analysis shows that: (1) the two cross-sectional networks are highly similar in terms of structure, existence of edges, centrality estimates, and the invariance test shows that there is no significant difference between them. The symptoms "follow through", "interrupts/intrudes", "difficulty playing quietly" and "concentration" had the highest expected influence centrality at both time points. (2) Combined with the results of the cross-sectional and cross-lagged networks, we found that "annoy" and "blame" are potential bridge symptoms between the ODD and ADHD symptom networks. The symptom "annoy" forms a reciprocal predictive relationship with "interrupts/intrudes", while "blame" unidirectionally predicts "close attention". In addition, we found that "vindictive" predicted numerous ADHD symptoms, whereas "angry" was predicted by numerous ADHD symptoms. The findings emphasize the broad predictive relationship between ODD and ADHD symptoms with each other, and that ODD symptoms may lead to activation of the ADHD symptom network and vice versa. These findings suggest that the developmental precursor model at the symptom level may partially explain the comorbidity mechanisms of ODD and ADHD, and future studies should further investigate the underlying multiple mechanisms.

Abstract
BACKGROUND Left-behind childre (LBC) in China are deeply concerned by society because of their high risk of emotional and behavioral problems. Depression and nonsuicidal self-injury are the most harmful and worrying negative emotional and behavioral problems in LBC. Unfortunately, LBCs are in unfavorable environments for a long time and are prone to negative interpersonal interactions. Child maltreatment and bullying victimization, as the two most typical negative interpersonal interactions in family and school environments, maybe the key risk factors for depression and nonsuicidal self-injury among LBCs. However, we are less known of the longitudinal effects of child maltreatment and bullying victimization on LBC's depression and nonsuicidal self-injury and their underlying mechanisms. AIMS This study used a two-year longitudinal design with three-time points to investigate the longitudinal effects of child maltreatment and bullying victimization on depression, nonsuicidal self-injury, and the mediating role of negative thoughts and self-compassion. MATERIALS & METHODS A sample of 592 LBC (390 were males, Mage at time 1 = 9.56, SDage = 0.65; 202 were females, Mage at time 1 = 9.43, SDage = 0.63) completed a set of questionnaires at three-time points. This study used SPSS software (version 25.0) and MPLUS software (version 8.3) for all analyses. RESULTS (1) Child maltreatment not only affects depression and nonsuicidal self-injury but also affects depression and nonsuicidal self-injury through negative thoughts. Child maltreatment affects depression through self-compassion and does not affect nonsuicidal self-injury. (2) Bullying victimization affects depression and nonsuicidal self-injury through negative thoughts and bullying victimization further affects depression through self-compassion but does not affect nonsuicidal self-injury. CONCLUSION This study revealed the effects of negative interpersonal interactions (child maltreatment, bullying victimization) on LBC's adverse emotions and behaviors, and their underlying mechanisms, which helps to provide parents, schools, and psychoeducational workers with a new perspective on intervention.

Abstract
The agile generation and control of multiple optical frequency modes combined with the realtime processing of multi-mode data provides access to experimentation in domains such as optomechanical systems, optical information processing, and multi-mode spectroscopy. The latter, specifically spectroscopy of spectral-hole burning (SHB), has motivated our development of a multi-mode heterodyne laser interferometric scheme centered around a software-defined radio platform for signal generation and processing, with development in an entirely open-source environment. A challenge to SHB is the high level of shot noise due to the laser power constraint imposed by the spectroscopic sample. Here, we have demonstrated the production, detection, and separation of multiple optical frequency modes to the benefit of optical environment sensing for realtime phase noise subtraction as well as shot noise reduction through multi-mode averaging. This has allowed us to achieve improved noise performance in low-optical-power interferometry. Although our target application is laser stabilization via SHB in cryogenic temperature rare-earth doped crystals, these techniques may be employed in a variety of different contexts.

Abstract
This work focused on exploring whether the long intergenic non-protein coding RNA LINC00958 is associated with the prognosis of head and neck squamous cell carcinoma (HNSCC). Associations of the LINC00958 expression level with clinicopathological features of HNSCC were investigated by logistic regression and Wilcoxon signed-rank test. The Kaplan-Meier method was applied to evaluate patient survival. Clinical data and expression profiles were obtained from The Cancer Genome Atlas (TCGA). Associations of patient clinical characteristics with overall survival (OS), progression-free interval (PFI), and disease-specific survival (DSS) were assessed by univariate and multivariate analysis using the Cox proportional hazard model. Immune cell infiltration analysis and gene set enrichment analysis (GSEA) were applied to determine any significant effects of LINC00958. High LINC00958 expression was related to early pT stage (P < 0.01), primary therapy outcome (P < 0.01), HPV status (P < 0.001), lymphovascular invasion (P < 0.001), and perineural invasion (P < 0.01). The receiver operating characteristic curve showed strong prognostic power for LINC00958 (area under curve = 0.886). High LINC00958 expression predicted poor OS (P = 0.007), DSS (P = 0.036), and PFI (P = 0.040). LINC00958 was related to signalling pathways and the infiltration of certain immune cells. miR-27b-5p was significantly associated with LINC00958, and downstream NT5E predicted poor survival in HNSCC cases. LINC00958 may affect the prognosis by regulating NT5E via miR-27b-5p, and could serve as a possible factor to predict the prognosis of HNSCC, especially oral squamous cell carcinoma.

Abstract
AIM To explore the potential of the joint radiomics analysis of positron-emission tomography (PET) and magnetic resonance imaging (MRI) of primary tumours for predicting the risk of synchronous distant metastasis (SDM) in patients with pancreatic ductal adenocarcinoma (PDAC). MATERIALS AND METHODS 18F-FDG PET and MRI images of PDAC patients from January 2011 to December 2020 were collected retrospectively. Patients (n=66) who received 18F-FDG PET/CT and MRI were included in a development group. Patients (n=25) scanned with hybrid PET/MRI were incorporated in an external test group. A radiomics signature was constructed using the least absolute shrinkage and selection operator algorithm to select PET-MRI radiomics features of primary PDAC tumours. A radiomics nomogram was developed by combining the radiomics signature and important clinical indicators using univariate and multivariate analysis to assess patients' metastasis risk. The nomogram was verified with the employment of an external test group. RESULTS Regarding the development cohort, the radiomics nomogram was found to be better for predicting the risk of distant metastasis (area under the curve [AUC]: 0.93, sensitivity: 87%, specificity: 85%) than the clinical model (AUC: 0.70, p<0.001; sensitivity:70%, specificity: 65%) and the radiomics signature (AUC: 0.89, p>0.05; sensitivity: 65%, specificity:100%). Concerning the external test cohort, the radiomics nomogram yielded an AUC of 0.85. CONCLUSION PET-MRI based radiomics analysis exhibited effective prediction of the risk of SDM for preoperative PDAC patients and may offer complementary information and provide hints for cancer staging.

Abstract
PURPOSE/OBJECTIVE(S) Xerostomia, caused by radiation-induced parotid damage, is the most commonly reported complications of radiotherapy (RT) to nasopharyngeal carcinoma (NPC). This study aimed to evaluate the value of IVIM MR in monitoring radiation parotid gland damage and predicting the risk of xerostomia. MATERIALS/METHODS A total of 54 patients were enrolled and underwent IVIM MR scans at before RT, after the fifth fraction, halfway through the course of RT, and at the end of radiotherapy. The parameters of IVIM MR include pseudo-diffusion coefficient (D*), perfusion fraction (f), and pure diffusion coefficient (D). The degree of xerostomia in NPC patients was assessed before each MR examination using the acute radiation morbidity scoring criteria proposed by the Radiation Therapy Oncology Group (RTOG). Concurrently, the time when the patient first reported suffering from xerostomia was recorded. The IVIM parameters trend throughout the RT, and the relationships between IVIM parameters and xerostomia, were analyzed. RESULTS All of the IVIM parameters increased from pre-RT to post-RT significantly (all p < 0.001). The increase rate of D from pre-RT to halfway through the RT was 32.61%, which was significantly higher than 15.64% from halfway to post-RT (p<0.001), indicating that cell necrosis in the first half of treatment is significantly higher than that in the second half. Both D* and F had significantly increased from pre-RT to halfway through the radiotherapy (p<0.001), with an increase rate of 19.58% and 29.38%, respectively. However, no significant increase was observed from Halfway to post-RT (p>0.05), with an increase rate of 4.10% and 8.30%, respectively. This may be due to radiation-induced vasculitic dilation that is significant in the first half of the radiotherapy but plateaus in the second half. Pre-D (OR = 23.85; 95% CI = 2.39, 237.82; p = .007) and pre-D* (OR = 0.75; 95% CI = 0.63, 0.91; p = 0.003) are independent influencing factors for xerostomia at 3 months after the completion of RT. D and F were significantly higher after the fifth fraction compared with Pre-RT (both p<0.05), respectively increased 31.25% and 25.16%. D* increase by 15% (p = 0.081). IVIM scans can assess parotid gland damage early. And the average time of parotid damage underwent IVIM scan was 5.99 ± 0.84 (day), much earlier than 11.84 ± 2.74 (day) according to RTOG. CONCLUSION Our study indicates that IVIM MR can dynamically monitor radiotherapy-induced parotid gland damage, and much earlier and objectively than RTOG.

Abstract
In humans, teeth are replaced only once, and the successional dental lamina (SDL) of the permanent tooth is maintained in a quiescent state until adolescence. Recently, we showed that biomechanical stress generated by the rapid growth of the deciduous tooth inhibits SDL development via integrin β1-RUNX2 signaling at embryonic day 60 (E60) in miniature pigs. However, the mechanism by which RUNX2 regulates SDL initiation within the SDL stem cell niche remains unclear. In the current study, we transcriptionally profiled single cells from SDL and surrounding mesenchyme at E60 and identified the landscape of cellular heterogeneity. We then identified a specific fibroblast subtype in the dental follicle mesenchyme between the deciduous tooth and the SDL of the permanent tooth (DFDP), which constitutes the inner part of the niche (deciduous tooth side). Compared with traditional dental follicle cells, the specific expression profile of DFDP was identified and found to be related to biomechanical stress. Subsequently, we found that RUNX2 could bind to the enhancer regions of Fbln1 (gene of fibulin-1), one of the marker genes for DFDP. Through gain- and loss-of-function experiments, we proved that the biomechanical stress-mediated RUNX2-fibulin-1 axis inhibits the initiation of SDL by maintaining SDL niche homeostasis.

Abstract
PURPOSE/OBJECTIVE(S) The PARP inhibitor talazoparib is synthetically lethal with HR-defective tumors and functions as a potent radiosensitizer specifically of cancer cells. Talazoparib exerts this unique radiosensitizing property by shifting ionizing radiation (IR)-induced DNA double strand break (DSB) repair towards error-prone alternative end-joining (alt-EJ). DNA polymerase theta (Polθ, encoded by POLQ) is a key component of alt-EJ. Here, we tested the hypothesis that inhibition of alt-EJ with Polθ ablation or using specific small molecule inhibitors can further increase talazoparib-induced radiosensitization. MATERIALS/METHODS U2OS, A549, and their corresponding POLQ ablated/mutant cell lines were treated with talazoparib and/or Polθ inhibitors ART558/novobiocin prior to irradiation. siRNAs against CtIP, MRE11, EXO1; and a specific inhibitor of DNA2 were employed to suppress DNA end resection. Radiosensitization was assessed by clonogenic survival. Olaparib, rucaparib, and veliparib were also tested under similar conditions. DSB repair and end resection were measured by scoring γH2AX and RPA nuclear foci, respectively. Chromosomal abnormalities were assessed using G2-specific cytogenetics analysis. RESULTS Genetic ablation or pharmacological inhibition of Polθ robustly enhanced talazoparib mediated radiosensitization by ∼40-70%. Notably, Polθ inhibition had a much lower effect (by ∼7-17%) when combined with other clinically used PARP inhibitors, olaparib, rucaparib, and veliparib. Polθ inhibition significantly suppressed talazoparib-induced translocation formation in irradiated cells. In addition, combined treatment with Polθ inhibitor and talazoparib attenuated DSB repair, resulting in ∼60% unresolved γH2AX foci and ∼40% unresolved chromatid breaks at 5h post IR. Talazoparib promoted resection of DNA ends as demonstrated by an increase in RPA foci. The resection process requires the activities of CtIP and MRE11, but not of DNA2 or EXO1. Finally, CtIP and MRE11 knockdown impaired radiosensitization following a combined talazoparib/Polθ inhibition treatment. CONCLUSION Talazoparib increases the reliance of irradiated cancer cells on Polθ-mediated alt-EJ owing to the increased CtIP/MRE11-dependent resection it produces. Combining talazoparib with Polθ inhibitors has therefore great potential in improving radiotherapy of human tumors.

Abstract
PURPOSE/OBJECTIVE(S) Metastasis-associated protein 3 (MTA3) can serve as a tumor suppressor in many cancer types. However, the role of MTA3 in radiosensitivity of patients with esophageal squamous cell cancer (ESCC) remains unclear. We thus investigated the function of MTA3 in radiosensitivity for ESCC, one of the most common digestive cancers. MATERIALS/METHODS The colony formation assay and nude mice xenograft tumor assay were performed to investigate the effect of MTA3 on radiosensitivity in ESCC. Glutamine consumption assay kit and glutamate production assay kit were used to assess the glutaminolysis. Glutaminase (GLS) Activity Assay Kit and Glutamine Synthetase (GS) Activity Assay Kit were used to analyze the activity of specific metabolic enzymes dominate glutaminolysis. The regulatory mechanism of glutaminolysis by MTA3 was confirmed using Chromatin immunoprecipitation assay and Gaussia luciferase assay. The expression levels of MTA3 and GS in ESCC primary tissues were evaluated using immunohistochemistry. Survival curves were plotted with the Kaplan-Meier method and compared by log-rank test. RESULTS The colony formation assay showed that MTA3 depletion and overexpression caused significantly higher and lower clonogenic survival after different doses of irradiation (IR), respectively. When these cells were subcutaneously injected into nude mice, the tumors derived from the cells with MTA3 overexpression and MTA3 knockdown were significantly smaller and bigger after IR, respectively. These findings suggest that MTA3 can enhance radiosensitivity in vitro and in vivo. Meanwhile, overexpressed and knockdown MTA3 can repress and expedite glutamine consumption and glutamate production uniformly, respectively. To determine how MTA3 acts on glutaminolysis, the activity of two specific metabolic enzymes dominate this metabolism, GS and GLS, were evaluated. It found that overexpressed and knockdown MTA3 can restrain and enhance the activity of GS, respectively, but have less effect on GLS. Moreover, the decreased radiosensitivity mediated by MTA3 knockdown is significantly increased when treated with GS inhibitor, suggesting that GS plays a crucial role in MTA3-mediated radiosensitivity enhancement. Mechanistically, Chromatin immunoprecipitation assay and Gaussia luciferase assay showed that MTA3 was recruited to the promoter of GS and suppressed GS transcription. However, knockdown of GATA3 abolished MTA3's repressive effect on GS and inhibited the MTA3's occupation on the promoter region of GS. These results collectively demonstrated that, in ESCC cells, MTA3 is recruited by GATA3 to inhibit GS expression, then ultimately represses glutaminolysis and enhances radiosensitivity. Finally, we showed that the ESCC patients in the MTA3low/GShigh group is significantly associated with shorter overall survival. CONCLUSION MTA3 is capable of enhancing radiosensitivity through downregulating GS and MTA3low/GShigh might be a potential prognostic factor for ESCC patients.

Abstract
Organoids are tissue cultures formed by culturing cells in three-dimensional environments that simulate the physiological or pathological conditions of the human body. The cultivation of organoids is used to study the temporal and spatial transformation of cells during the development of tissues or organs, to investigate changes in cellular functions and inter-communications caused by various risk factors, and to discover potential therapeutic targets. This article provided an overview of the cultivation and identification methods of alveolar organoids, as well as the research progress in their application to common respiratory diseases such as pulmonary fibrosis, chronic obstructive pulmonary disease, viral pneumonia, and so on. The limitations and future applications of alveolar organoids are also analyzed and discussed.

Abstract
Element isotopes are characterized by distinct atomic masses and nuclear spins, which can significantly influence material properties. Notably, however, isotopes in natural materials are homogenously distributed in space. Here, we propose a method to configure material properties by repositioning isotopes in engineered van der Waals (vdW) isotopic heterostructures. We showcase the properties of hexagonal boron nitride (hBN) isotopic heterostructures in engineering confined photon-lattice waves-hyperbolic phonon polaritons. By varying the composition, stacking order, and thicknesses of h10BN and h11BN building blocks, hyperbolic phonon polaritons can be engineered into a variety of energy-momentum dispersions. These confined and tailored polaritons are promising for various nanophotonic and thermal functionalities. Due to the universality and importance of isotopes, our vdW isotope heterostructuring method can be applied to engineer the properties of a broad range of materials.

Abstract
Introduction During emergencies, individuals and communities often react in a variety of ways, including panic response. However, the study of panic response is limited due to narrow assessment tools that measure only one or two dimensions of human response (eg, physiology, cognition, emotion, and behavior). To address this limitation and to explore the risk and protective factors of panic response during the global spread of the Coronavirus Disease 2019 (COVID-19), the current study developed and evaluated the Panic Response Scale (PRS). Methods Four samples were recruited for the following purposes: interview analysis (n = 26); item analysis and exploratory factor analysis (n = 604); confirmatory factor analysis and reliability analysis (n = 603); and retest reliability, validity analysis, and regression analysis (n = 349). Results The PRS consists of 21 items with four subscales: Physical Discomfort, Anxious Fluster, Sensitive Depression, and Excessive Prevention. Each of these subscales demonstrated good internal consistency (rs > 0.73), test-retest reliability (rs > 0.77), criterion validity (r = 0.69, p < 0.01), and convergent validity (rs = 0.31-0.65, p < 0.01). Regression analysis revealed significant predicting effects of COVID-19 knowledge and neuroticism on panic response. Additionally, cognitive reappraisal moderated the association between neuroticism and panic response. Discussion Following a traumatic event, the PRS offers a potential tool for identifying individuals in need of mental health services. Moreover, during the COVID-19 pandemic, knowledge and neuroticism served as risk factors for heightened panic response, while cognitive reappraisal served as a protective factor for coping with panic response.

Abstract
Objective: To explore the characteristics of orthokeratology lenses designed for small correction zones and their effectiveness and safety in long-term prevention and control of myopia in children and adolescents. Methods: It was a prospective cohort study that included myopic children and adolescents who received corneal reshaping treatment at the Qingdao Eye Hospital of Shandong First Medical University between January 2019 and May 2020. The patients were randomly divided into two groups using computer-generated randomization, and were fitted with corneal reshaping lenses with small treatment zones and conventional designs, respectively. The uncorrected visual acuity, best-corrected visual acuity, refractive error, and axial length were measured before and after 6, 12, and 18 months of wearing the lenses. Corneal topography with the Pentacam was also performed, and the area and diameter of the corneal treatment zone were calculated using the Matlab software. Results: A total of 60 myopic patients (60 eyes) were enrolled, including 29 males and 31 females, with an age of (10.40±1.01) years and a spherical equivalent of (-2.88±0.42) D. There were 30 cases in the small correction zone group and 30 cases in the conventional group. There was no significant difference in uncorrected visual acuity and spherical equivalent between the two groups at each time point after treatment. The axial growth in the conventional group was (0.16±0.09) mm at 6 months after treatment, (0.28±0.17) mm at 12 months, and (0.37±0.20) mm at 18 months, whereas in the small treatment zone group it was (0.06±0.05) mm, (0.12±0.10) mm, and (0.18±0.14) mm, respectively. The myopia progression rate in the small treatment zone group was only 37.50%, 42.86%, and 48.64% of the conventional group at 6, 12, and 18 months, respectively. Corneal topography showed that the treatment area in the conventional group was (6.98±0.89) mm², while in the small treatment zone group it decreased by 23.2% [(5.36±0.73) mm²] (P<0.05). Correlation analysis revealed that the axial increase after 18 months of lens wearing was negatively correlated with the age before lens wearing (P<0.05), positively correlated with the corneal surface treatment zone size (P<0.05), and not correlated with the pupil diameter and spherical equivalent (all P>0.05). After the shaping treatment, the rate of adverse reaction, which was mild, in both groups was 10%, and the symptoms disappeared. Conclusion: Orthokeratology lenses with smaller treatment zones can significantly reduce the rate of axial length growth in children and adolescents compared to lenses with conventional treatment zones, without compromising treatment safety.

Abstract
BACKGROUND Childhood maltreatment has a severe impact on both the health and parenting styles of abused individuals in adulthood, and it even has a negative impact on the offspring of abused individuals. Although studies have confirmed the intergenerational effects of childhood maltreatment, relatively few have emphasized emotional neglect and its mechanism of intergenerational effects. Additionally, few studies have examined the unique role of fathers and how mothers and fathers interact with one another. OBJECTIVE The current study aimed to employ the actor-partner interdependence mediation model to investigate the relationship between parental childhood emotional neglect and children's problem behaviors, as well as whether parents' positive and negative emotional expressiveness plays a mediating role. METHODS, PARTICIPANTS, AND SETTING In total, 397 dyads of mothers and fathers of children aged 6-9 were recruited and reported their childhood emotional neglect experience and emotional expressiveness, and mothers also rated their children's problem behaviors. RESULTS The findings revealed that (a) maternal childhood emotional neglect was associated solely with mothers' own negative emotional expressiveness, followed by their children's problem behavior and (b) paternal childhood emotional neglect showed no effect on children's problem behavior through fathers' own or their spouses' positive and negative emotional expressiveness. CONCLUSIONS The findings of this study suggest that childhood emotional neglect has intergenerational effects and that mothers' parenting behaviors are relatively important in preventing adverse effects on their children.

Abstract
Based on the network theory of mental disorders, this study used network analysis to examine the network of ODD symptoms and multilevel family factors and identify the most crucial family factors influencing ODD symptoms in children. A total of 718 Chinese migrant children aged 7-14 years participated in this study. This study measured ODD symptoms, family system-level variables (3 factors), family dyadic-level variables (6 factors), and family individual-level variables (6 factors) with factors selected based on the multilevel family factors theory of ODD symptoms. The results indicated that (1) "annoy" was the center symptom of ODD, (2) "annoy" and "vindictive" was the main bridge connecting the multilevel family factors, and (3) family cohesion at the family system level, parent-child conflict at the family dyadic level, and parental depression at the family individual level were critical central and bridging influencing factors. The findings of this study highlight the critical role of "annoy" and "vindictive" symptoms in the activation of ODD symptom networks in children and provide a basis for future improvements in diagnostic criteria. These potential core and bridge factors might become key intervention targets for childhood ODD.

Abstract
Objective: The direction and intensity of population aging on the burden of non-communicable diseases (NCDs) in China from 1990 to 2019 were analyzed, and the burden of NCDs in 2050 was predicted. Methods: The disease-specific disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) in the Chinese population from 1990 to 2019 were obtained from the Global Burden of Disease Study.The differences in indicators from 1990 to 2019 were attributed to the contribution of age structure, population size, and all other causes. The Bayesian age-time-cohort models were used to predict DALYs from NCDs to 2050. Results: The absolute level of DALYs caused by NCDs increased by 7.460 million from 1990 to 2019, and the age structure contributed 186.0% (95% Uncertainty Intervals (UIs): 178.4%-193.6%), population size contributed 77.0% (95% UIs: 69.5%-80.8%), all other causes contributed -163.0% (95% UIs:-163.1%- -159.3%). DALYs caused by NCDs consist of 2.527 million YLLs and 4.934 million YLDs, in which the contribution of age structure to YLLs and YLDs was 414.6% (95% UIs: 396.2%-432.5%) and 69.1% (95% UIs: 66.7%-71.4%), respectively. From 2019 to 2050, the diseases with increased DALYs due to changes in age structure are cardiovascular diseases, neoplasms, chronic respiratory diseases, neurological disorders, sense organ diseases, diabetes and kidney diseases, musculoskeletal disorders, digestive diseases, mental disorders, and skin and subcutaneous diseases in descending order. Conclusions: From 1990 to 2019, except for skin and subcutaneous diseases, the burden of other NCDs attributable to population aging increased, mainly due to disability. By 2050, the burden of NCDsattributable to population aging will continue to rise.

Abstract
This study aimed to investigate the effect of irisin on LPS-induced inflammation in RAW 264.7 macrophages through inhibition of the mitogen-activated protein kinase (MAPK) pathway. A network pharmacology-based approach, combined with molecular docking and in vitro validation were performed to identify the biological activity, key targets, and potential pharmacological mechanisms of irisin against LPS-induced inflammation. By matching 100 potential genes of irisin with 1893 ulcerative colitis (UC) related genes, 51 common genes were obtained. Using protein-protein interaction networks (PPI) and component-target network analysis,10 core genes of irisin on UC were further identified. The results of gene ontology (GO) enrichment analysis showed that the molecular mechanisms of irisin on UC were mainly related to major enrichment in the categories of response to xenobiotic stimulus, response to the drug, and negative regulation of gene expression. Molecular docking results showed good binding activity for almost all core component targets. More importantly, MTT assay and flow cytometry results showed that LPS-induced cytotoxicity was reversed by irisin, after coincubation with irisin, the level of IL-12 and IL-23 decreased in LPS-stimulated RAW264.7 macrophages. Irisin pretreatment significantly inhibited the phosphorylation of ERK and AKT and increased the expression of PPAR alpha and PPAR gamma. LPS-induced enhancement of phagocytosis and cell clearance were reversed by irisin pretreatment. Irisin ameliorated LPS-induced inflammation by inhibiting cytotoxicity and apoptosis, and this protective effect may be mediated through the MAPK pathway. These findings confirmed our prediction that irisin plays an anti-inflammatory role in LPS-induced inflammation via the MAPK pathway.

Abstract
Parenting is crucial for emotion regulation in children. Much less is known, however, concerning the association between parenting and emotion regulation in children with oppositional defiant disorder (ODD), who are known to have poor emotion regulation. The current study aimed to examine how parental responsiveness and child emotion regulation related either unidirectionally or bidirectionally to one another over time and to investigate whether the associations were different in ODD and non-ODD groups. Data were collected each year for three consecutive years from a sample of 256 parents of children with ODD and 265 parents of children without ODD in China. The results from the random intercepts cross-lagged panel model (RI-CLPM) suggested that the directionality of the link between parental responsiveness and child emotion regulation differs according to ODD status. The non-ODD group demonstrated a unidirectional link between early emotion regulation and subsequent parental responsiveness, consistent with the "child effect". However, in the ODD group, the link between parental responsiveness and emotion regulation was transactional, in line with social coercion theory. Multiple-group comparisons found that increased parental responsiveness was more strongly associated with improved child emotion regulation in the ODD group only. The research established a dynamic and longitudinal relationship between parental responsiveness and emotion regulation and suggested that intensive interventions should aim to improve parental responsiveness to children with ODD.

Abstract
A strong link between children's emotion regulation and oppositional defiant disorder (ODD) symptoms has been documented; however, the within-person mechanisms remain unclear. Based on the self-control theory and self-regulation theory, our study investigated the longitudinal, bidirectional relationship between emotion regulation and ODD symptoms in school-age children with ODD using parent- and teacher-reported data, respectively. A total of 256 Chinese elementary school students participated in a three-wave longitudinal study spanning two years. We used the random intercept cross-lagged panel model (RI-CLPM) to investigate the concurrent and longitudinal associations between emotion regulation and ODD symptoms. Results from the RI-CLPMs revealed that ODD symptoms were negatively correlated with emotion regulation and positively correlated with emotion lability/negativity at both the between-person and within-person levels across settings. Additionally, in the school setting, emotion regulation negatively predicted subsequent ODD symptoms but not vice versa, whereas emotion lability/negativity was bidirectionally associated with ODD symptoms over time. The longitudinal associations of ODD symptoms with emotion regulation and lability/negativity were not observed in the home setting. These findings suggest a circular mechanism between children's emotion regulation and ODD symptoms and support the view that emotion regulation, particularly emotion lability/negativity, plays an important role in the development of ODD symptoms.

Abstract
Root apical complex, including Hertwig's epithelial root sheath, apical papilla, and dental follicle (DF), is the germinal center of root development, wherein the DF constantly develops into periodontal tissue. However, whether DF development is regulated by the adjacent apical papilla remains largely unknown. In this study, we employed a transwell coculture system and found that stem cells from the apical papilla (SCAPs) inhibit the differentiation and maintain the stemness of dental follicle stem cells (DFSCs). Meanwhile, partial SCAP differentiation markers were upregulated after DFSC coculture. High-throughput RNA sequencing revealed that the Hedgehog (Hh) pathway was significantly downregulated in DFSCs cocultured with SCAPs. Upregulation or downregulation of the Hh pathway can respectively activate or inhibit the multidirectional differentiation of DFSCs. Osteoglycin (OGN) (previously known as mimecan) is highly expressed in the dental papilla, similarly to Hh pathway factors. By secreting OGN, SCAP regulated the stemness and multidirectional differentiation of DFSCs via the OGN-Hh pathway. Finally, Ogn-/- mice were established using the CRISPR/Cas9 system. We found that the root length growth rate was accelerated during root development from PN0 to PN30 in Ogn-/- mice. Moreover, the hard tissues (including dentin and cementum) of the root in Ogn-/- mice were thicker than those in wild-type mice. These phenotypes were likely due to Hh pathway activation and the increased cell proliferation and differentiation in both the apical papilla and DF. The current work elucidates the molecular regulation of early periodontal tissue development, providing a theoretical basis for future research on tooth root biology and periodontal tissue regeneration.

Abstract
Polyploidization is a driving force in plant evolution. Chromosomal variation often occurs at early generations following polyploid formation due to meiotic pairing irregularity that may compromise segregation fidelity and cause homoeologous exchange (HE). The trends of chromosomal variation and especially factors affecting HE remain to be fully deciphered. Here, by whole-genome resequencing, we performed nuanced analyses of patterns of chromosomal number variation and explored genomic features that affect HE in two early generations of a synthetic rice segmental allotetraploid. We found a wide occurrence of whole-chromosome aneuploidy and, to a lesser extent, also large segment gains/losses in both generations (S2 and S4) of the tetraploids. However, while the number of chromosome gains was similar between S2 and S4, that of losses in S4 was lower than in S2. HEs were abundant across all chromosomes in both generations and showed variable correlations with different genomic features at chromosomal and/or local scales. Contents of genes and transposable elements (TEs) were positively and negatively correlated with HE frequencies, respectively. By dissecting TEs into different classes, retrotransposons were found to be negatively correlated with HE frequency to a stronger extent than DNA transposons, whereas miniature terminal inverted elements (MITEs) showed a strong positive correlation. Local HE frequencies in the tetraploids and homologous recombination (HR) rates in diploids within 1 Mb sliding windows were significantly correlated with each other and showed similar overall distribution profiles. Nonetheless, non-concordant trends between HE and HR rates were found at distal regions in some chromosomes. At local scale, both shared and polymorphic retrotransposons between parents were negatively correlated with HE frequency; in contrast, both shared and polymorphic MITEs showed positive correlations with HE frequency. Our results shed new light on the patterns of chromosomal number variation and reveal genomic features influencing HE frequency in early generations following plant polyploidization.

Abstract
The extensive usage of metal oxide nanoparticles has aided in the spread and accumulation of these nanoparticles in the environment, potentially endangering both human health and the agroecological system. This research describes in detail the hazardous and advantageous impacts of common metal oxide nanomaterials, such as iron oxide, copper oxide, and zinc oxide, on the life cycle of rice. In-depth analyses are conducted on the transport patterns of nanoparticles in rice, the plant's reaction to stress, the reduction of heavy metal stress, and the improvement of rice quality by metal oxide nanoparticles, all of which are of significant interest in this subject. It is emphasized that from the perspective of advancing the field of nanoagriculture, the next stage of research should focus more on the molecular mechanisms of the effects of metal oxide nanoparticles on rice and the effects of combined use with other biological media. The limitations of the lack of existing studies on the effects of metal oxide nanomaterials on the entire life cycle of rice have been clearly pointed out.

Abstract
AIM To investigate whether spleen imaging characteristics of baseline 2-[18F]-fluoro-2-deoxy-d-glucose (18F-FDG) positron-emission tomography (PET)/computed tomography (CT) can help to predict the clinical outcome in complete response (CR) diffuse large B-cell lymphoma (DLBCL). MATERIALS AND METHODS Three hundred and six patients with DLBCL were enrolled in the study and divided into recurrence and non-recurrence groups. The splenic abnormalities were compared using the chi-square test and quantitative indexes were compared using the t-test. The Cox proportional hazard regression model was used for univariate and multivariate analysis. Kaplan-Meier curves and log-rank tests were used to compare progression-free survival (PFS). Propensity score matching (PSM) was used to match patients with and without splenic abnormalities according to age, gender, and initial Ann Arbor stage at a 1:2 ratio (52:104); then the recurrence and PFS results were compared again. RESULTS Age, international prognostic index (IPI), stage, splenomegaly, and focal splenic lesions were significantly different between the recurrence and non-recurrence groups. IPI, stage, baseline spleen mean standard uptake value (SUVmean)/liver SUVmean, splenomegaly, and focal lesions were selected by Cox single-factor analysis, and only focal lesions showed a statistical difference in terms of Cox multivariate analysis (p=0.022, hazard ratio [HR]: 2.843). After PSM, focal splenic lesions (n=20) were still statistically different (p=0.003) between the recurrence and non-recurrence groups, and this played an essential role in PFS forecasting (p=0.0004, HR: 3.767). CONCLUSION Focal splenic lesions were identified as an independent risk factor for the prognosis of DLBCL. Pretreatment splenomegaly and focal splenic lesions appeared to be related to the relapse and PFS of DLBCL patients. Focal splenic lesions still showed meaningful predictive value even with propensity matching.

Abstract
Objective: To review the clinical data of 7 patients with Danon disease and analyze their clinical characteristics. Methods: The medical records of 7 patients with Danon disease, who were hospitalized in Peking Union Medical College Hospital of Chinese Academy of Medical Sciences from April 2008 to July 2021, were reviewed and summarized, of which 6 cases were diagnosed as Danon disease by lysosomal-associated membrane protein-2 (LAMP-2) gene mutation detection and 1 case was diagnosed by clinicopathological features. Clinical manifestations, biochemical indexes, electrocardiogram, echocardiography, skeletal muscle and myocardial biopsy and gene detection results were analyzed, and patients received clinical follow-up after discharge. Results: Six patients were male and average age was (15.4±3.5) years and the average follow-up time was (27.7±17.0) months. The main clinical manifestations were myocardial hypertrophy (6/7), decreased myodynamia (2/7) and poor academic performance (3/7). Electrocardiogram features included pre-excitation syndrome (6/7) and left ventricular hypertrophy (7/7). Echocardiography examination evidenced myocardial hypertrophy (6/7), and left ventricular dilatation and systolic dysfunction during the disease course (1/7). The results of skeletal muscle biopsy in 6 patients were consistent with autophagy vacuolar myopathy. Subendocardial myocardial biopsy was performed in 3 patients, and a large amount of glycogen deposition with autophagosome formation was found in cardiomyocytes. LAMP-2 gene was detected in 6 patients, and missense mutations were found in all these patients. During the follow-up period, implantable cardioverter defibrillator implantation was performed in 1 patient because of high atrioventricular block 4 years after diagnosis, and there was no death or hospitalization for cardiovascular events in the other patients. Conclusion: The main clinical manifestations of Danon disease are cardiomyopathy, myopathy and mental retardation. Pre-excitation syndrome is a common electrocardiographic manifestation. Autophagy vacuoles can be seen in skeletal muscle and myocardial pathological biopsies. LAMP-2 gene mutation analysis is helpful in the diagnose of this disease.

Abstract
To comprehensively understand the Chinese family relationships (i.e., marital relationship, parent-child relationship, sibling relationship, and grandparent-grandchild relationship) during the COVID-19 pandemic, this study investigated the changes of family relationships and the individual differences related to knowledge of the COVID-19, personality traits (i.e., neuroticism and optimism), and emotional characteristics (i.e., emotion regulation and negative emotional reactions). From March 1 to April 5, 2020, 8821 participants were involved, including 3995 teenagers, 1146 unmarried young adults, 3571 married adults, and 109 grandparents. Results revealed a double-edged pattern that people experienced both positive changes and negative changes during the pandemic. Teenagers reported significant negative changes in the relationships with their parents. Peoples' knowledge of the COVID-19, neuroticism, optimism, emotion regulation, and negative emotional reactions were in varying extents to which accounted for the individual differences in the changes of family relationships. These findings help recognize the overall Chinese family relationships during the hard period.

Abstract
The purpose of this study is to identify the latent profiles of Chinese adolescents' family (parent-adolescent and sibling) relationships prior to and during the COVID-19 pandemic, as well as associations between those profiles and adolescents' emotional and behavioral responses. A total of 2,305 adolescents from China aged between 10 and 18 years completed measures of parent-adolescent relationships, sibling relationships, and emotional and behavioral responses during the pandemic. Four profiles of family relationships were identified via latent profile analysis and categorized as Cohesive-Decline, Mild-Decline, Conflictual-Stable, and Indifferent-Stable. Adolescents with a Conflictual-Stable profile reported more emotional and behavioral responses compared to the other profiles. In contrast, adolescents with a Cohesive-Decline profile exhibited fewer emotional responses compared to the other profiles. Adolescents with a Mild-Decline profile had fewer emotional responses than those with an Indifferent-Stable profile. These results shed light on the patterns and consequences of family relationships during the COVID-19 pandemic and have substantial implications for interventions involving family relationships in the context of regular epidemic prevention and control.

Abstract
OBJECTIVE Chemoresistance is one of the main obstacles in the clinical treatment of cancer. However, secondary resistance to paclitaxel poses new challenges for cancer treatment. Long noncoding RNAs regulate cellular functions at different levels and mechanisms and play an important role in the biological behavior of tumors. MATERIALS AND METHODS LncRNA microarrays were used to detect lncRNAs in Paclitaxel-resistant cells and corresponding parental cells. Cell counting kit 8 and Transwell analysis were used to test the effect of lncRNA on function. RESULTS The expression of lncRNA DBH-AS1 in TE-4 TAX-R cells was significantly higher than that in TE-4 cells. Transwell analysis showed that the overexpression of lncRNA DBH-AS1 increased the invasion of Eca cells. Cell scratches and Transwell analysis showed that the overexpression of lncRNA DBH-AS1 in Eca cell culture supernatants promoted the migration and invasion of HUVEC. In addition, lncRNA DBH-AS1 relies on miR-21 to regulate the expression of YOD1. CONCLUSIONS Paclitaxel-resistant lncRNA DBH-AS1 appears to promote ECa cell proliferation and invasion by acting as a ceRNA and regulating miR-21-5p /YOD1 signaling pathway.

Abstract
The current study aims to clarify the longitudinal relations among parent emotion regulation (ER), child ER, and children's oppositional defiant disorder (ODD) symptoms. In the current study, parents of 275 children (195 boys, 70.1%) with ODD symptoms (Mage = 9.32 years, SD = 1.64) reported their ER using the Difficulties in Emotion Regulation Scale, child ERs using the Emotion Regulation Checklist, and children's ODD symptoms using the eight symptoms indicated in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) at three time points (T1, T2, and T3) within 2 years. Results indicated the longitudinal relationships between parent ER and children's ODD symptoms were directly influenced by each other. Children's ODD symptoms had important effects on both child ER and parent ER. Findings suggested that to reduce children's ODD symptoms, it is necessary not only to improve child ER but also to improve parent ER.

Abstract
Objective: To analyze the spatiotemporal distribution of life expectancy (LE) and health-adjusted life expectancy (HALE) in Guangzhou from 2010 to 2019, and quantize the comprehensive impact of different causes and sequelae on health. Methods: The LE, HALE, and cause-excluded health adjusted life expectancy (CEHALE) were estimated using cause-of-death surveillance datasets from Guangzhou Municipal Center for Disease Control and Prevention from 2010 to 2019 and open data from the Global Burden of Disease Study. Joinpoint log-linear regression model was used to analyze the temporal trend and described spatial distribution. Results: In 2019, the LE in residents in Guangzhou was 82.9 years (80.1 years in men and 85.9 years in women), and the HALE was 75.6 years (74.0 years in men and 77.3 years in women). Compared with the urban fringe, the central urban area had higher LE and HALE, and the differences between LE and HALE were small. The LE and HALE in Guangzhou showed an increasing trend from 2010 to 2019. The LE increased by 2.8 years (AAPC=0.4, 95%CI: 0.3-0.4), with the increase of 2.8 years in men and 2.9 years in women. The HALE increased by 2.4 years (AAPC=0.3, 95%CI: 0.3-0.4), with the increase of 2.5 years in men and 2.2 years in women. The median healthy life lost due to communicable, maternal, neonatal, and nutritional diseases was 6.2 years (AAPC=-4.2, 95%CI: -5.3--3.1), while the median healthy life lost due to non-communicable diseases was 14.7 years (AAPC=1.6, 95%CI: 0.9-2.3), the median healthy life expectancy reduced by injury was 6.3 years (AAPC=-3.5, 95%CI: -4.5--2.6). Musculoskeletal disorders, skin and subcutaneous diseases, cardiovascular diseases, nutritional deficiencies, diabetes and kidney diseases were the top five diseases causing healthy life expectancy loss. Conclusion: The LE and HALE in residents in Guangzhou increased steadily from 2010 to 2019, but the quality of life in the urban fringe was lower than that of the central urban area. Non-communicable diseases were the leading causes of healthy life expectancy loss. Health policies and prevention measures should be developed according to area specific characteristics, and social medical resources should be rationally allocated to key diseases to reduce their disease burden.

Abstract
Oppositional Defiant Disorder (ODD) is characterized by a recurrent pattern of angry/irritable emotional lability, argumentative/defiant behavior, and vindictiveness. Previous studies indicated that ODD typically might originate within a maladaptive family environment, or was at least maintained within such an environment. As such, the present review summarized pertinent research from the last 20 years that focused on the pathways connecting family risk factors to the development of child ODD symptoms. A systematic search of electronic databases was completed in August 2020, resulting in the inclusion of 62 studies in the review. The review established a multi-level framework to describe the mechanisms underlying the pathway from familial factors to ODD psychopathological symptoms: (a) the system level that is affected by the family's socioeconomic status and family dysfunction; (b) the dyadic level that is affected by conflict within the marital dyad and parent-child interactions; and (c) the individual level that is affected by parent and child factors. Additionally, from the perspective of family systems theory, we pay special attention to the interactions among and between the various levels of the pathway (moderation and mediation) that might be associated with the occurrence and severity of ODD symptoms. Considering future prevention and intervention efforts, this three-level model emphasizes the necessity of focusing on familial risk factors at multiple levels and the mechanisms underlying the proposed pathways.

Abstract
Child maltreatment is negatively associated with subjective well-being in emerging adulthood, but the understanding of the mechanisms of this relationship is incomplete. Guided by the stress process model incorporated with a life-course perspective, the present study examined the protective roles of self-related resources (self-esteem and self-compassion) in this association, while considering various maltreatment types (physical abuse, physical neglect, emotional abuse, emotional neglect, and sexual abuse). The Childhood Trauma Questionnaire-Short Form, Rosenberg Self-esteem Scale, Self-compassion Scale, and Satisfaction with Life Scale were used to measure the key variables through an online survey of 358 Chinese college students (226 females, mean age = 19.18) Direct effect of one type of maltreatment on life satisfaction and the three indirect effects through (a) self-esteem; (b) self-compassion; and (c) self-esteem and self-compassion in sequence were examined while controlling for age, gender, and the other four maltreatment types. The results showed that psychological maltreatment was negatively associated with life satisfaction through self-esteem and through the pathway from self-esteem to self-compassion. Indirect effects of the other three types of maltreatment were not significant. This suggests that self-processes are more vulnerable to psychological maltreatment than to other maltreatment types. The type of maltreatment experienced in childhood is worth considering when investigating the extending effect of child maltreatment on individual developmental outcomes. Our findings broaden the understanding of the mechanisms of the stress process model integrated with a life-course perspective. Self-related resources appear to play substantial roles in the long-term association between early stressors of psychological maltreatment in childhood and subjective well-being in emerging adulthood. Highlighting the need to work on improved self-related resources, including self-compassion and self-esteem, might help practitioners to provide treatment for survivors of adverse childhood experiences..

Abstract
Objective: To evaluate the influence of duodenal stump reinforcing on the short-term complications after laparoscopic radical gastrectomy. Methods: A retrospective cohort study with propensity score matching (PSM) was conducted. Clinical data of 1204 patients with gastric cancer who underwent laparoscopic radical gastrectomy at the First Affiliated Hospital of Army Medical University from April 2009 to December 2018 were collected. The digestive tract reconstruction methods included Billroth II anastomosis, Roux-en-Y anastomosis and un-cut-Roux- en-Y anastomosis. A linear stapler was used to transected the stomach and the duodenum. Among 1204 patients, 838 were males and 366 were females with mean age of (57.0±16.0) years. Duodenal stump was reinforced in 792 cases (reinforcement group) and unreinforced in 412 cases (non-reinforcement group). There were significant differences in resection range and anastomotic methods between the two groups (both P<0.001). The two groups were matched by propensity score according to the ratio of 1∶1, and the reinforcement group was further divided into purse string group and non-purse string group. The primary outcome was short-term postoperative complications (within one month after operation). Complications with Clavien-Dindo grade ≥ III a were defined as severe complications, and the morbidity of complication between the reinforcement group and the non-reinforcement group, as well as between the purse string group and the non-purse string group was compared. Results: After PSM, 411 pairs were included in the reinforcement group and the non-reinforcement group, and there were no significant differences in baseline data between the two groups (all P>0.05). No perioperative death occurred in any patient.The short-term morbidity of postoperative complication was 7.4% (61/822), including 14 cases of anastomotic leakage (23.0%), 11 cases of abdominal hemorrhage (18.0%), 8 cases of duodenal stump leakage (13.1%), 2 cases of incision dehiscence (3.3%), 6 cases of incision infection (9.8%) and 20 cases of abdominal infection (32.8%). Short-term postoperative complications were found in 25 patients (6.1%) and 36 patients (8.8%) in the reinforcement group and the non-reinforcement group, respectively, without significant difference (χ2=2.142, P=0.143). Nineteen patients (2.3%) developed short-term severe complications (Clavien-Dindo grade ≥IIIa), while no significant difference in severe complications was found between the two groups (1.7% vs. 2.9%, χ2=1.347, P=0.246). Sub-group analysis showed that the morbidity of short-term postoperative complication of the purse string group was 2.6% (9/345), which was lower than 24.2% (16/66) of the non-purse string group (χ2=45.388, P<0.001). Conclusion: Conventional reinforcement of duodenal stump does not significantly reduce the incidence of duodenal stump leakage, so it is necessary to choose whether to reinforce the duodenal stump individually, and purse string suture should be the first choice when decided to reinforce.

Abstract
Skeletal stem/progenitor cells (SSPCs) are critical for fracture repair by providing osteo-chondro precursors in the callus, which is impaired in aging. However, the molecular signatures of callus SSPCs during aging are not known. Herein, we performed single-cell RNA sequencing on 11,957 CD45-CD31-Ter119- SSPCs isolated from young and aged mouse calluses. Combining unsupervised clustering, putative makers, and DEGs/pathway analyses, major SSPC clusters were annotated as osteogenic, proliferating, and adipogenic populations. The proliferating cluster had a differentiating potential into osteogenic and adipogenic lineages by trajectory analysis. The osteoblastic/adipogenic/proliferating potential of individual clusters was further evidenced by elevated expression of genes related to osteoblasts, adipocytes, or proliferation. The osteogenic cluster was sub-clustered into house-keeping and inflammatory osteogenic populations that were decreased and increased in aged callus, respectively. The majority of master regulators for the inflammatory osteogenic population belong to IRF and NF-κB families, which was confirmed by immunostaining, RT-qPCR, and Western blot analysis. Furthermore, cells in the inflammatory osteogenic sub-cluster had reduced osteoblast differentiation capacity. In conclusion, we identified 3 major clusters in callus SSPCs, confirming their heterogeneity and, importantly, increased IRF/NF-κB-mediated inflammatory osteogenic population with decreased osteogenic potential in aged cells.

Abstract
Enormous evidences in clinic and experimental studies have demonstrated that salvianolate (Sal) could treat cardiovascular diseases such as myocardial infarction (MI), but the underlying mechanism was still needed to be explored. This study aims to investigate the effect of Sal on cardiomyocyte remodeling after MI in rats and explore whether the possible mechanism was related to decreasing the β-myosin heavy chain (β-MHC) expression in cardiomyocytes via the calcineurin (CaN)/nuclear factor C3 of the activated T cell (NFATc3) pathway. Both MI model and angiotensin II induced primary myocardial cells obtained from rats were used in this study. After treatment with Sal, the cardiac function was assessed by color Doppler echocardiography, while MI area, myocardial cell area and heart mass index (HMI) were analyzed via Masson and hematoxylin and eosin staining (HE) stain, respectively. Additionally, CaN activity, and CaN, NFATc3, β-MHC mRNA and protein expressions in myocardial tissue and myocardial cells were tested via corresponding methods, mainly including real-time fluorescence-based quantitative polymerase chain reaction (RT-qPCR), Western blot (WB), immunohistochemistry and fluorescence staining analysis. As a result we obtained the high dose of Sal in vivo could perform beneficial effects on cardiomyocyte remodeling of MI rats, mainly manifesting as improving fractional shortening and ejection fraction rates, reducing the MI area, myocardial cross-sectional area and HMI (P<0.05, 0.01), inhibiting the activity of CaN in myocardial tissue, down-regulating b-MHC mRNA and protein expressions, and decreasing the nuclear translocation of NFATc3 (P<0.05). In the in vitro experiments, 10 μmol/L of Sal could inhibit the increase of the myocardial cell area and CaN activity, down-regulate the mRNA and protein of CaN A subunit, β-MHC; and inhibit the nuclear translocation of NFATc3 (P<0.05, 0.01). In conclusion: use of Sal can improve cardiomyocyte remodeling and down-regulate the expression of β-MHC in cardiomyocytes, of which the mechanism might be related to the reduction of the nuclear translocation of NFATc3 as well as the down-regulation of CaNA subunit expression and/or the inhibition of CaN activity. The results will provide a laboratory basis for the clinical application of Sal.

Abstract
The current study summarized the clinical characteristics of 8 patients with central nervous system anaerobic infections who visited the Second Hospital of Hebei Medical University from June 2019 to June 2021. Among the 8 patients, 7 cases had headache and fever as the first symptoms, and 1 case had left-sided limb weakness as the first symptom. Four patients had a previous history of diabetes (1 patient had a history of tooth extraction before the onset of the disease), 1 patient had a previous history of sinusitis, 1 patient had a history of tooth extraction before the onset of the disease, and 2 patients had chronic extensive periodontitis or periapical periodontitis. Five cases showed abnormal intracranial and/or meningeal enhancement on cranial magnetic resonance imaging (MRI), and 1 case showed swelling of the whole brain tissue on cranial computed tomography (CT). After treatment, symptoms of 4 cases were improved, symptoms of 1 case were aggravated, and 3 cases died. Anaerobic infections can occur in various parts of the body:the central nervous system, oral cavity, head and neck, chest, abdomen, pelvis, skin and soft tissues. It is generally believed that anaerobic bacteria rarely cause central nervous system infection, therefore, anaerobic culture of cerebrospinal fluid is usually not performed. Moreover, anaerobic culture is affected by many factors, and thus it is difficult to obtain positive results. Metagenomic next-generation sequencing can identify multiple pathogens (viral, bacterial, fungal, or parasitic) from samples based on DNA and/or RNA sequences and has advantages in diagnosing anaerobic infections of the central nervous system. Prompt empirical antimicrobial therapy is essential for the prognosis of the patients.

Abstract
BACKGROUND During the COVID-19 pandemic, wearing PPE can induce skin damage such as erythema, pruritus, erosion, and ulceration among others. Although the skin microbiome is considered important for skin health, the change of the skin microbiome after wearing PPE remain unknown. OBJECTIVE The present study aimed to characterize the diversity and structure of bacterial and fungal flora on skin surfaces of healthcare workers wearing personal protective equipment (PPE) during the COVID-19 pandemic using metagenomic next-generation sequencing (mNGS). METHODS A total of 10 Chinese volunteers were recruited and the microbiome of their face, hand, and back were analyzed before and after wearing PPE. Moreover, VISIA was used to analyze skin features. RESULTS Results of alpha bacterial diversity showed that there was statistically significant decrease in alpha diversity indice in the skin samples from face, hand, and three sites after wearing PPE as compared with the indice in the skin samples before wearing PPE. Further, the results of evaluated alpha fungal diversity show that there was a statistically significant decrease in alpha diversity indices in the skin samples from hand after wearing PPE as compared with the indices in the skin samples before wearing PPE (P<0.05). Results of the current study found that the main bacteria on the face, hand, and back skin samples before wearing the PPE were Propionibacterium spp. (34.04%), Corynebacterium spp. (13.12%), and Staphylococcus spp. (38.07%). The main bacteria found on the skin samples after wearing the PPE were Staphylococcus spp. (31.23%), Xanthomonas spp. (26.21%), and Cutibacterium spp. (42.59%). The fungal community composition was similar in three skin sites before and after wearing PPE. CONCLUSION It was evident that wearing PPE may affect the skin microbiota, especially bacteria. Therefore, it was evident that the symbiotic microbiota may reflect the skin health of medical workers during the COVID-19 pandemic.

METHODS Immunohistochemistry and Western blotting were used to detect the localization and expression level of Talin1 in the fallopian tube and chorionic villi in patients with tubal pregnancy and in women with normal pregnancy. In the cell experiment, HTR-8/SVneo cells was transfected with Talin1 siRNA and the changes in cell invasion and migration were assessed using scratch assay and Transwell assay. The expressions of MMP-2, MMP-9, N-cadherin and Snail in the transfected cells were detected by qRT-PCR and Western blotting. RESULTS Positive expression of Talin1 was detected in both normal fallopian tube tissues and tissues from women tubal pregnancy, and its expression was localized mainly in the cytoplasm of cilia cells. The expression level of Talin1 was significantly higher in both the fallopian tube and chorionic villi in women with tubal pregnancy than in normal fallopian tube and chorionic villi samples (P < 0.01). In HTR-8/SVneo cells, transfection with Talin1 siRNA significantly inhibited cell invasion (P < 0.01) and migration (P < 0.05), down-regulated the expression of N-cadherin, MMP-2 and Snail (P < 0.05), and up-regulated the expression of MMP-9 in the cells (P < 0.05). CONCLUSION The expression of Talin1 in the fallopian tube and chorionic villi is significantly increased in women with tubal pregnancy, suggesting the association of Talin1-regulated trophoblast cell invasion with the occurrence of tubal pregnancy.
