Abstract
BACKGROUND Little is known about the effectiveness of treprostinil in higher-risk paediatric patients with various pulmonary arterial hypertension genotypes. This study was designed to investigate the prognosis of higher-risk paediatric patients with idiopathic or heritable pulmonary arterial hypertension (IPAH/HPAH) after treprostinil therapy. METHODS Children with IPAH/HPAH who were stratified as higher risk and treated with treprostinil in our centre were included as the study cohort. Those who received only oral medications were included as the reference cohort. All patients in the study cohort received PAH-related genotyping. Survival was defined as no death. Event-free survival was defined as no death, Potts shunt, or atrial septostomy. RESULTS Forty-nine children (median age 7.7 years [interquartile range (IQR) 4.2-11.5 years], 65% female) were included in the study cohort and 48 children were included in the reference cohort; 84% of the study cohort had genetic disorders after genetic testing with a dominance of BMPR2 and ACVRL1 mutations. After a median therapy duration of 5.56 months (IQR 2.66-11.12 months), all patients were alive with significant improvements in clinical characteristics. One-, 2-, and 3-year survival rates were 91%, 84%, and 69%, respectively with a median follow-up duration of 19.17 months (IQR 9.7-29.79 months), which was significantly superior to the reference cohort (P = 0.038). Multivariate Cox regression analysis identified World Health Organisation functional class after therapy as a predictor for survival. There was no significant difference in survival among patients with different genotypes. CONCLUSIONS Treprostinil can significantly improve the prognosis in children with IPAH/HPAH who are at higher risk, despite genetic backgrounds.

Abstract
OBJECTIVE This study aimed to explore Chinese clients' experiences with family dynamic change throughout family therapy for school refusal and the interventions adolescents and their parents identified as useful during family therapy. METHODS A multiperspective interpretative phenomenology analysis (IPA) was adopted. Thirty-two participants from 11 Chinese families with school-refusing adolescents were recruited after completing family therapy at the hospitals. Semistructured interviews were conducted with the families, and the transcripts were analyzed. RESULTS Four main superordinate themes emerged: reshaping healthy family boundaries, building a harmonious family atmosphere, learning to cooperate and fight against stress, and achieving individual growth. CONCLUSION Our analysis suggested that changes in school-refusing adolescents through family therapy consisted of multilevel factors. These factors influence the reversal of adolescents' school refusal. Some targeted interventions for Chinese adolescents who refuse school are discussed and suggested.

Abstract
BACKGROUND Mandibular distraction osteogenesis (MDO) is a highly effective method for bone regeneration, commonly employed in treating craniofacial defects and deformities. Osteocytes sense mechanical forces in the pericellular space, relay external stimuli to biochemical changes, and send signals to other effector cells, including bone marrow mesenchymal stem cells (BM-MSCs), to regulate bone resorption and formation. Piezo1 potentially affects the secretion signal molecules of bone cells under mechanical stretch. The primary aim of this study was to enhance our comprehension of the molecular biology underlying this therapeutic approach and to identify specific signaling molecules that facilitate bone formation in response to stretch forces. METHODS Mechanical stretching was applied to negative controls and Piezo1 knockdown osteocyte-like MLO-Y4 cells. Alkaline phosphatase and Alizarin Red S staining were used to survey the osteogenic potential of BM-MSCs. The production and secretion content of adenosine triphosphate (ATP) was measured using ATP content determination analysis. Pathway-related and osteo-specific genes and proteins were evaluated using real-time polymerase chain reaction (RT-PCR), Western blots, and immunofluorescence. Mitochondrial organization was examined with a transmission electron microscope. RESULTS The conditioned medium of stretch-exposed MLO-Y4s significantly upregulated osteogenesis-related indicators of BM-MSCs (p < 0.001). The upregulation of BM-MSC osteogenesis was associated with ATP release from osteocytes. Mechanically induced calcium transfer and transcriptional coactivator with PDZ-binding motif (TAZ) nuclear translocation mediated by Piezo1 could promote mitochondrial fission and ATP release. Osteocytes detected stretch forces through Piezo1, triggering calcium influx, TAZ nuclear translocation, and ATP production. CONCLUSIONS The stretch stimulation of Piezo1 induces calcium influx, which in turn promotes calcium-related TAZ nuclear translocation, changes in mitochondrial dynamics, and the release of ATP in osteocytes. This signaling cascade leads to an up-regulation in the osteogenic capacity of BM-MSCs. Mitochondrial energy metabolism of mechanosensitive protein Piezo1-dependent and ATP release may provide a new effective intervention method for mechanically related bone remodeling.

Abstract
Echinococcosis poses a significant threat to public health. The Chinese government has implemented prevention and control measures to mitigate the impact of the disease. By analyzing data from the Chinese Center for Disease Control and Prevention and the State Council of the People's Republic of China, we found that implementation of these measures has reduced the infection rate by nearly 50% between 2004 to 2022 (from 0.3975 to 0.1944 per 100,000 person-years). Nonetheless, some regions still bear a significant disease burden, and lack of detailed information limites further evaluation of the effects on both alveolar and cystic echinococcosis. Our analysis supports the continuing implementation of these measures and suggests that enhanced wildlife management, case-based strategies, and surveillance systems will facilitate disease control.

Abstract
PURPOSE To evaluate the myopia risk in school-aged children one year after lifting a pandemic-related lockdown and develop a tool to identify high-risk groups. METHODS In total, 38,079 children without myopia from 38 schools were included. The outcomes were myopia incidence and progression in 1 year after the COVID-19 lockdown was lifted, both obtained by the spherical equivalent refraction (SER). We separated the population into an exploratory (75%) and a validation sample (25%) to construct the risk score model. RESULTS In total, 9811 (29.57%) students became myopic, and the overall myopia progression was 0.22 ± 0.62 D. Even less myopia progression was noted in the pre-myopia group at baseline (All: P = 0.045, Boy: P = 0.005). The risk score model included seven predictors: gender, grade, SER at baseline, residence, parental myopia, eye discomfort symptoms, and online courses. The model had a score range of 0-46 and an optimal cutoff of 34. The area under the receiver operating curve of the model was 0.726 (0.719-0.732) for the exploratory sample and 0.731 (0.720-0.742) for the validation sample. CONCLUSIONS The risk score can serve as a practical tool for classifying the risk of myopia in school-aged children.

Abstract
Non-Negative Matrix Factorization (NMF) is a widely used dimension reduction method that factorizes a non-negative data matrix into two lower dimensional non-negative matrices: one is the basis or feature matrix which consists of the variables and the other is the coefficients matrix which is the projections of data points to the new basis. The features can be interpreted as sub-structures of the data. The number of sub-structures in the feature matrix is also called the rank. This parameter controls the model complexity and is the only tuning parameter for the NMF model. An appropriate rank will extract the key latent features while minimizing the noise from the original data. However due to the large amount of optimization error always present in the NMF computation, the rank selection has been a difficult problem. We develop a novel rank selection method based on hypothesis testing, using a deconvolved bootstrap distribution to assess the significance level accurately. Through simulations, we compare our method with a rank selection method based on hypothesis testing using bootstrap distribution without deconvolution and a method based on cross-validation; we demonstrate that our method is not only accurate at estimating the true ranks for NMF, especially when the features are hard to distinguish, but also efficient at computation. When applied to real microbiome data (eg, OTU data and functional metagenomic data), our method also shows the ability to extract interpretable subcommunities in the data.

Abstract
The mammalian brain is composed of diverse neuron types that play different functional roles. Recent single-cell RNA sequencing approaches have led to a whole brain taxonomy of transcriptomically-defined cell types, yet cell type definitions that include multiple cellular properties can offer additional insights into a neuron's role in brain circuits. While the Patch-seq method can investigate how transcriptomic properties relate to the local morphological and electrophysiological properties of cell types, linking transcriptomic identities to long-range projections is a major unresolved challenge. To address this, we collected coordinated Patch-seq and whole brain morphology data sets of excitatory neurons in mouse visual cortex. From the Patch-seq data, we defined 16 integrated morpho-electric-transcriptomic (MET)-types; in parallel, we reconstructed the complete morphologies of 300 neurons. We unified the two data sets with a multi-step classifier, to integrate cell type assignments and interrogate cross-modality relationships. We find that transcriptomic variations within and across MET-types correspond with morphological and electrophysiological phenotypes. In addition, this variation, along with the anatomical location of the cell, can be used to predict the projection targets of individual neurons. We also shed new light on infragranular cell types and circuits, including cell-type-specific, interhemispheric projections. With this approach, we establish a comprehensive, integrated taxonomy of excitatory neuron types in mouse visual cortex and create a system for integrated, high-dimensional cell type classification that can be extended to the whole brain and potentially across species.

Abstract
Retinal ischemia-reperfusion injury (RIRI) is a vital pathological process of multiple ocular diseases. This study aimed at investigating the effects of the MIAT/miR-203-3p/SNAI2 axis on RIRI. RIRI was produced by inducing an exceedingly high intraocular pressure (IOP) in mice. Mouse retinal ganglion cells (RGCs) were subjected to oxygen-glucose deprivation/reoxygenation (OGD/R) to mimic in vitro models. Relevant oligonucleotides or plasmids were transfected into OGD/R-induced RGCs in vitro or injected into RIRI mice models in vivo via a vitreous cavity. The findings of our paper indicated that MIAT and SNAI2 were highly expressed and miR-203-3p was lowly expressed in mouse RIRI tissues and OGD/R-induced RGCs. Interfering MIAT promoted the viability of OGD/R-induced RGCs, decreased apoptosis, and reduced oxidative stress in vitro. Silencing MIAT increased retinal neuronal cell numbers and decreased retinal neuronal cell apoptosis in mouse RIRI tissues in vivo. MIAT sponged miR-203-3p, and miR-203-3p targeted and inhibited SNAI2 expression. SNAI2 up-regulation or miR-203-3p down-regulation reversed the protective effects of MIAT down-regulation on RIRI in mice and OGD/R-induced RGCs. MIAT sponges miR-203-3p upregulated the expression of SNAI2, thereby promoting RIRI in mice. In summary, MIAT may be a therapeutic target for the treatment of chronic RIRI.

Abstract
AIMS Despite shared pathophysiological mechanisms, patients with idiopathic/heritable pulmonary arterial hypertension (IPAH/HPAH) have a poorer prognosis than those with PAH after congenital heart defect repair. Ventricular adaption remains unclear and could provide a basis for explaining differences in clinical outcomes. The aim of this prospective study was to assess clinical status, haemodynamic profile, and biventricular adaptation to PAH in children with various forms of PAH. METHODS AND RESULTS Consecutive patients with IPAH/HPAH or post-operative PAH were prospectively recruited (n = 64). All patients underwent a comprehensive, protocolized assessment including functional assessment, measurement of brain natriuretic peptide (BNP) levels, invasive measurements, and a cardiac magnetic resonance (CMR) assessment. A cohort of age- and sex-matched healthy subjects served as controls. Patients with post-operative PAH had a better functional class (61.5 vs. 26.3% in Class I/II, P = 0.02) and a longer 6-min walk distance (320 ± 193 vs. 239 ± 156 m, P = 0.008) than IPAH/HPAH. While haemodynamic parameters were not significantly different between IPAH/HPAH and post-operative patients, post-operative patients with PAH presented with higher left ventricular volumes and better right ventricular function compared with patients with IPAH/HPAH (P < 0.05). On correlation analyses, left ventricular volumetric parameters were highly correlated with BNP and 6-min walk test distance in this population. CONCLUSION Despite comparable haemodynamic profiles, patients with post-operative PAH had less functional limitation than their IPAH/HPAH counterparts. This is potentially related to the differential biventricular adaptation pattern evident on CMR with better myocardial contractility and higher left ventricular volumes in post-operative patients with PAH, highlighting the importance of ventriculo-ventricular interaction in the setting of PAH.

Abstract
BACKGROUND Long-term clinical outcomes after pulmonary artery denervation (PADN) in patients with Group 1 pulmonary arterial hypertension (PAH) have not been reported. AIMS We aimed to investigate the effect of PADN on 1-year outcomes in patients with PAH. METHODS In the multicentre PADN-CFDA trial, 128 patients with Group 1 PAH were randomly assigned to PADN plus a phosphodiesterase-5 inhibitor (PDE-5i) versus a sham PADN procedure plus a PDE-5i. The principal endpoint of interest for the present study was clinical worsening at 1 year after randomisation, the composite of worsening of PAH (increase in WHO functional class, need for additional PAH treatments or PAH-related hospitalisation), atrial septostomy, listing for lung transplantation, or all-cause death. RESULTS One-year clinical follow-up was available in all patients. At 1 year, clinical worsening had occurred in 3 (4.8%) patients in the PADN plus PDE-5i group and in 15 patients (23.1%) in the sham plus PDE-5i group (adjusted hazard ratio: 0.17; 95% confidence interval [CI]: 0.05-0.60; p=0.006), driven by significantly increased rates of PAH-related hospitalisations, worsening functional class and the requirement for additional PAH treatments in the sham group. Results were consistent in high-risk, intermediate-risk and low-risk patients (pinteraction=0.186). Patients treated with PADN plus PDE-5i had an improvement in the between-group change in the six-minute walking distance (6MWD) from baseline to 1 year of 81.2 m (95% CI: 50.3-112.2; p<0.001) compared with PDE-5i treatment alone. CONCLUSIONS In this multicentre sham-controlled randomised trial, PADN treatment for Group 1 PAH significantly reduced clinical worsening and improved the 6MWD during 1-year follow-up in patients treated with a PDE-5i.

Abstract
BACKGROUND By creating networks of biochemical pathways, communities of micro-organisms are able to modulate the properties of their environment and even the metabolic processes within their hosts. Next-generation high-throughput sequencing has led to a new frontier in microbial ecology, promising the ability to leverage the microbiome to make crucial advancements in the environmental and biomedical sciences. However, this is challenging, as genomic data are high-dimensional, sparse, and noisy. Much of this noise reflects the exact conditions under which sequencing took place, and is so significant that it limits consensus-based validation of study results. RESULTS We propose an ensemble approach for cross-study exploratory analyses of microbial abundance data in which we first estimate the variance-covariance matrix of the underlying abundances from each dataset on the log scale assuming Poisson sampling, and subsequently model these covariances jointly so as to find a shared low-dimensional subspace of the feature space. CONCLUSIONS By viewing the projection of the latent true abundances onto this common structure, the variation is pared down to that which is shared among all datasets, and is likely to reflect more generalizable biological signal than can be inferred from individual datasets. We investigate several ways of achieving this, demonstrate that they work well on simulated and real metagenomic data in terms of signal retention and interpretability, and recommend a particular implementation.

Abstract
OBJECTIVE This study aimed to identify risk factors associated with the development of pulmonary arterial hypertension (PAH) in patients with systemic lupus erythematosus (SLE). METHODS We conducted a systematic literature review of studies focusing on adult patients classified as having SLE-related PAH by searching the electronic databases Embase, Medline, Medline in-progress, Wanfang, China National Knowledge Infrastructure, Ichushi Web, Kmbase, and KoreaMed. Based on the findings, we conducted a Delphi survey to build expert consensus on issues related to screening for PAH in patients with SLE and on the importance and feasibility of measuring the identified factors in clinical practice. RESULTS We included 21 eligible studies for data synthesis. Sixteen factors were associated with an increased risk of SLE-PAH: pericardial effusion, serositis, longer duration of SLE, arthritis, acute and subacute cutaneous lupus, scleroderma pattern on nailfold capillaroscopy, diffusion capacity of carbon monoxide in the lungs (DLCO) <70% predicted, interstitial lung disease, thrombocytopenia, and seven serological factors. Six factors were associated with a decreased risk of SLE-PAH: malar/acute rash, hematologic disorder, renal disorder, higher Systemic Lupus Erythematosus Disease Activity Index score, and two serological factors. Among these, there were six risk factors on which the panelists reached strong or general consensus (peak tricuspid regurgitation velocity on echocardiography >2.8 m/s, pericardial effusion, DLCO <70% predicted, scleroderma pattern on nailfold capillaroscopy, brain natriuretic peptide >50 ng/l, and N-terminal pro-brain natriuretic peptide >300 ng/l). The Delphi panel confirmed the need for a screening tool to identify patients with SLE at high risk of developing PAH and provided consensus on the importance and/or practicality of measuring the identified factors. CONCLUSION The risk factors we identified could be used in a screening algorithm to identify patients with SLE with a high risk of developing PAH to facilitate early diagnosis, which could improve prognosis and management of these patients.

Abstract
BACKGROUND Cognitive function and general psychopathology are two important classes of human behavior dimensions that are individually related to mental disorders across diagnostic categories. However, whether these two transdiagnostic dimensions are linked to common or distinct brain networks that convey resilience or risk for the development of psychiatric disorders remains unclear. METHODS The current study is a longitudinal investigation with 11,875 youths from the Adolescent Brain Cognitive Development (ABCD) Study at ages 9 to 10 years at the onset of the study. A machine learning approach based on canonical correlation analysis was used to identify latent dimensional associations of the resting-state functional connectome with multidomain behavioral assessments including cognitive functions and psychopathological measures. For the latent resting-state functional connectivity factor showing a robust behavioral association, its ability to predict psychiatric disorders was assessed using 2-year follow-up data, and its genetic association was evaluated using twin data from the same cohort. RESULTS A latent functional connectome pattern was identified that showed a strong and generalizable association with the multidomain behavioral assessments (5-fold cross-validation: ρ = 0.68-0.73 for the training set [n = 5096]; ρ = 0.56-0.58 for the test set [n = 1476]). This functional connectome pattern was highly heritable (h2 = 74.42%, 95% CI: 56.76%-85.42%), exhibited a dose-response relationship with the cumulative number of psychiatric disorders assessed concurrently and at 2 years post-magnetic resonance imaging scan, and predicted the transition of diagnosis across disorders over the 2-year follow-up period. CONCLUSIONS These findings provide preliminary evidence for a transdiagnostic connectome-based measure that underlies individual differences in the development of psychiatric disorders during early adolescence.

Abstract
Cryptotanshinone and ophiopogonin D are sourced from herbs with similar indications. It is necessary to evaluate their interaction to provide a reference for their clinical prescriptions. The co-administration of cryptotanshinone (30 and 60 mg/kg) and ophiopogonin D was carried out in Sprague-Dawley rats and the pharmacokinetics of cryptotanshinone were analyzed. The Caco-2 cells were employed to evaluate the transport of cryptotanshinone, and the metabolic stability was studied in the rat liver microsomes. Ophiopogonin D significantly increased the Cmax (from 5.56 ± 0.26 to 8.58 ± 0.71 μg/mL and from 15.99 ± 1.81 to 185.12 ± 1.43 μg/mL), half-life (21.72 ± 10.63 vs. 11.47 ± 3.62 h and 12.58 ± 5.97 vs. 8.75 ± 2.71 h) and decreased the clearance rate (0.697 ± 0.36 vs. 1.71 ± 0.15 L/h/kg) and (60 mg/kg and 0.101 ± 0.02 vs. 0.165 ± 0.05 L/h/kg) of cryptotanshinone. In vitro, ophiopogonin D significantly suppressed the transport of cryptotanshinone with the decreasing efflux rate and enhanced the metabolic stability with the reducing intrinsic clearance. The combination of cryptotanshinone and ophiopogonin D induced prolonged exposure and suppressed the transport of cryptotanshinone, which indicated the decreased bioavailability of cryptotanshinone.

Abstract
BACKGROUND Pulmonary hypertension (PH) is considered to increase maternal and fetal risk, and we attempt to explore pregnancy outcomes in women with different types of PH. METHODS We retrospectively analyzed the clinical data of pregnant women with PH who were admitted to Anzhen Hospital from January 2010 to December 2019, and followed up on these parturients and their offspring. RESULTS Three hundred and sixty-six pregnant women with PH were collected, including 265 pulmonary arterial hypertension (PAH) associated with congenital heart disease (CHD), 65 PH caused by left heart disease, 12 idiopathic PH, and 24 PH associated with other diseases. Maternal mean age was 28.4 ± 4.4 years and 72.1% were nulliparous. The estimated systolic pulmonary artery pressure was < 50 mmHg in 40.2% of patients, 50-70 mmHg in 23.2%, and > 70 mmHg in 36.6%. In more than 94% of women, a diagnosis of PH was made before pregnancy. During pregnancy, heart failure occurred in 15% of patients. Cesarean section was performed in 90.5% (20.4% emergency). Complications included fetal mortality (0.5%), preterm delivery (40.4%), and low birth weight (37.7%). A total of 20 mothers died (5.5%). The highest mortality rate was found in patients with idiopathic PH (4/12, 33.3%). A total of 12 children died (3.3%), 5 (1.4%) of them after discharge from the hospital, and 7 (1.9%) were in hospital. CONCLUSIONS Although most of these women are fertile, PH does increase maternal and fetal risk. Women with idiopathic PH and Eisenmenger syndrome are not recommended to have children.

Abstract
BACKGROUND The differential treatment effect of pulmonary artery denervation (PADN) in pulmonary arterial hypertension (PAH) patients with different risk burdens remains unclear. This study aimed to determine the effectiveness of PADN in low vs intermediate-high-risk PAH patients. METHODS In total, 128 patients with treatment naive PAH included in the PADN-CFDA trial were categorized into low-risk and intermediate-high-risk patients. The primary endpoint was the between-group difference in the change in 6-min walk distance (6 MWD) from baseline to 6 months. RESULTS In the intermediate-high-risk group, those treated with PADN and PDE-5i had a greater improvement in 6 MWD from baseline to 6 months as compared to those treated with sham plus PDE-5i. From baseline to 6 months, pulmonary vascular resistance (PVR) was reduced by -6.1 ± 0.6 and -2.0 ± 0.7 Wood units following PADN plus PDE-5i and sham plus PDE-5i, respectively, along with the significant reduction of NT-proBNP in the intermediate-high-risk group. However, there were no significant differences in 6 MWD, PVR, and NT-proBNP between the PADN plus PDE-5i and sham plus PDE-5i groups among low-risk patients. Moreover, the right ventricular function was equally improved by PADN treatment across the low-, intermediate-, and high-risk groups. Clinical worsening was less with PADN plus PDE-5i treatment during the 6-month follow-up. CONCLUSIONS In patients with pulmonary arterial hypertension, pulmonary artery denervation plus PDE-5i improved exercise capacity, NT-proBNP, hemodynamic, and clinical outcomes during the 6-month follow-up among intermediate-high risk patients.

Abstract
BACKGROUND Long-term benefits of pulmonary artery denervation (PADN) for patients with combined precapillary and postcapillary pulmonary hypertension (CpcPH) secondary to left heart failure are unknown. OBJECTIVES The authors sought to report the 3-year clinical results of PADN for patients with CpcPH. METHODS A total of 98 patients with CpcPH, defined as having mean pulmonary arterial pressure of ≥25 mm Hg, pulmonary capillary wedge pressure of >15 mm Hg, and pulmonary vascular resistance of >3.0 WU, were randomly assigned to receive the sham + sildenafil or PADN. The primary endpoint was the occurrence of clinical worsening defined as cardiopulmonary death, rehospitalization or heart/lung transplantation at 3-year follow-up. Changes in the 6-minute walk distance and N-terminal pro-B-type natriuretic peptide served as secondary points. RESULTS At the 3-year follow-up, clinical worsening was reported in 49 (50.0%) patients, with 31 (62.0%) in the sham + sildenafil group and 18 (37.5%) in the PADN group (HR: 2.13 [95% CI: 1.19-3.81]; P = 0.011), largely driven by a higher rate of rehospitalization in the sham + sildenafil group (56.2% vs 35.4%; HR: 1.96 [95% CI: 1.07-3.58]; P = 0.029) by Cox proportional hazards regression. At the end of the study, cardiopulmonary-related deaths occurred in 16 (32.0%) patients in the sham and 9 (18.8%) (P = 0.167) patients in the PADN group. PADN also resulted in a more profound increase in the 6-minute walk distance and reduction in N-terminal pro-B-type natriuretic peptide. CONCLUSIONS PADN is associated with significant improvements in exercise capacity, cardiac function, and clinical outcomes. Further study without approved drugs for pulmonary arterial hypertension is required to confirm the benefits of PADN for patients with CpcPH.

Abstract
Advances in the prevention, diagnosis, and treatment for congenital heart disease (CHD), the most common birth defect in China, have drastically improved survival for individuals with the disease. However, China's current health system is not well prepared to manage the growing population of people with CHD and their complex medical needs, which range from early detection of the condition and intervention for physical, neurodevelopmental, and psychosocial impairment, to long-term management of major complications and chronic health problems. Health disparities caused by long-standing regional differences in access to care pose challenges when major complications such as pulmonary hypertension arise, and when individuals with complex CHD become pregnant and give birth. Currently, no data sources track neonates, children, adolescents, and adults with CHD in China and delineate their clinical characteristics and use of health resources. This scarcity of data should warrant attention from the Chinese Government and relevant specialists in the field. In the third paper of the Series on CHD in China, we summarise key literature and current data to identify knowledge gaps and call for concerted efforts by the government, hospitals, clinicians, industries, and charitable organisations to develop an actionable, lifelong framework of congenital cardiac care that is accessible and affordable for all individuals with CHD.

Abstract
Objective The histological conversion of lung adenocarcinoma (LUAD) into small-cell lung cancer (SCLC) is an important resistance mechanism for epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI)-resistant LUAD. Anlotinib has been recommended as the third-line treatment for SCLC patients. The efficacy of etoposide/platinum (EP) as the main treatment is very limited for patients with transformed SCLC. However, little is known about EP plus anlotinib for transformed SCLC. The present study retrospectively explored the clinical response to EP combined with anlotinib in patients with transformed SCLC from LUAD after EGFR-TKI failure. Methods A total of 10 patients who underwent SCLC transformation from EGFR-TKI-resistant LUAD were retrospectively reviewed from September 1, 2019, to December 31, 2022, in three regional hospitals. All of the patients were treated with the combination regimen of EP and anlotinib for four to six cycles, followed by anlotinib maintenance therapy. The clinical efficacy indices including objective response rate (ORR), disease control rate (DCR), median progression-free survival (mPFS), median overall survival (mOS), and toxicities were evaluated. Results The median time from EGFR-TKI treatment to SCLC conversion was 20.1 ± 2.76 months (17-24 months). Genetic examination after transformation showed that 90% of the patients retained their original EGFR gene mutations. Additional driver genes were found, including BRAF mutation (10%), PIK3CA mutation (20%), RB1 loss (50%), and TP53 mutation (60%). The ORR and DCR were 80% and 100%, respectively. The mPFS was 9.0 months (95% CI, 7.9-10.1 months), and the mOS was 14.0 months (95% CI, 12.0-15.9 months). Less than 10% of grade 3 toxicities were observed, and no grade 4 toxicity and death events were reported. Conclusion The EP plus anlotinib regimen appears to be a promising and safe strategy in transformed SCLC patients after EGFR-TKI resistance, which warrants further investigation.

Abstract
BACKGROUND Substance use disorder is conceptualized as a neuropsychiatric disease with multifaceted phenotypic manifestations including disrupted interactions between brain networks. While the current understanding of brain network interactions is mostly based on static functional connectivity, accumulating evidence suggests that temporal dynamics of these network interactions may better reflect brain function and disease-related dysfunction. We thus investigated brain dynamics in cocaine use disorder and assessed their relationship with cocaine dependence severity. METHODS Using a time frame analytical approach on resting-state functional magnetic resonance imaging data of 54 cocaine users and 54 age- and sex-matched healthy control participants, we identified temporally recurring brain network configuration patterns, termed brain states. With Menon's triple network model as a guide, we characterized these state dynamics by quantifying their occurrence rate and transition probability. Group differences in the state dynamics and their association with cocaine dependence were assessed. RESULTS Three recurrent brain states with spatial patterns resembling the default mode, salience, and executive control networks were identified. Compared with healthy control subjects, cocaine users showed a higher default mode state occurrence rate and higher probability of transitioning from the salience state to the default mode state, with the former being attributed to the latter. A composite state transition probability negatively correlated with cocaine dependence severity. CONCLUSIONS Our results provide novel evidence supporting the triple network model. While confirming hyperactivity of default mode network in cocaine users, our findings indicate the failure of salience network in toggling between default mode and executive control networks in cocaine use disorder.

Abstract
Rituximab is a widely used anti-CD20 monoclonal antibody with a high incidence of infusion-related reactions (IRRs) during administration. Reducing the incidence of IRRs remains problematic in hematological practices. In the present study, a novel strategy of a prednisone pretreatment regimen was designed similar to the combination of rituximab, cyclophosphamide, epirubicin, vincristine and prednisone (R-CHOP) with the aim of exploring the effect on the incidence of IRRs to rituximab in patients with diffuse large B-cell lymphoma (DLBCL). A prospective, randomized (1:1) and controlled study was conducted in three regional hospitals in two groups (n=44 for each group): i) A control group treated with standard R-CHOP-like regimen; and ii) a group receiving a prednisone-pretreatment, modified R-CHOP-like protocol for newly diagnosed patients with DLBCL. The primary endpoint was to assess the incidence of IRRs to rituximab, as well as the association of IRRs with the efficacy of treatment. The second endpoint involved clinical outcomes. The total incidence of IRRs to rituximab in the treatment group was significantly lower compared with that in the control group (15.9 vs. 43.2%; P=0.0051). The different grade incidence of IRRs was lower in the treatment group compared with that in the control group (P=0.0053). In total, 29.5% of patients (26/88) experienced >1 IRR episode. The incidence of IRRs in the pre-treatment group was decreased compared with that in the control group in the 1st cycle (15.9 vs. 43.2%; P=0.0051) and 2nd cycle (6.8 vs. 27.3%; P=0.0107). The overall response rate was similar between the two groups (P>0.05). Median progression-free survival and median overall survival time were not statistically distinct between the two groups (P=0.5244 and P=0.5778, respectively). Grade ≥III toxicities mainly included vomiting and nausea (<20%), leukopenia and granulocytopenia (<20%), and alopecia (<25%). No death events were reported. Apart from IRRs to rituximab, the incidence of other adverse events was similar in both groups. The novel prednisone-pretreatment R-CHOP-like protocol in the present study significantly decreased the total and different grade incidences of IRRs to rituximab among newly diagnosed patients with DLBCL. This clinical trial was retrospectively registered with the Chinese Clinical Trial Registry (registration number, ChiCTR2300070327; date of registration, 10 April 2023).

Abstract
Objective: To compare the point-of-care assays for tear matrix metalloproteinase 9 (MMP-9) using domestic and InflammaDry kits, and to evaluate the feasibility of diagnosing dry eye with the domestic kit. Methods: It was a cross-sectional study. Thirty dry eye patients and 30 age-and sex-matched normal volunteers were continuously enrolled in this cross-sectional study from June 2022 to July 2022. Both domestic and InflammaDry kits were used to detect the tear MMP-9 levels. The positive rates were recorded for qualitative analysis, and the gray ratios of bands (the gray value of detection bands to that of control bands) were collected for quantitative analysis. The correlations of MMP-9 levels with age, ocular surface disease index, fluorescence tear break-up time, tear meniscus height, Schirmer's Ⅰ test score, corneal fluorescein staining score, and meibomian gland dropout were analyzed. The Mann-Whitney U test, paired Chi-square test, Kappa test, and Spearman's correlation coefficient were used for statistical analysis. Results: There were 14 males and 16 females (30 eyes) in the control group, and their age was (39.37±19.55) years. In the dry eye group, 11 males and 19 females (30 eyes), aged (46.87±17.85) years, had moderate to severe dry eye. The positive rates of MMP-9 in tear fluid were significantly different between dry eye patients (InflammaDry: 86.67%; domestic kit: 70.00%) and controls (InflammaDry: 16.67%, P<0.001; domestic kit: 6.67%, P<0.001). Although the sensitivity of the domestic kit was lower than that of the InflammaDry kit (70.0% vs. 86.7%, P=0.001), the specificity was higher (93.3% vs. 83.3%, P=0.001). In dry eye patients, the positive coincidence rate was 80.7% (21/26), the negative coincidence rate was 100% (4/4), and the total coincidence rate was 83.3% (25/30), with no significant difference between the two kits (McNemar test: χ2=3.20, P>0.05), and the results of both kits were consistent (Kappa=0.53, P=0.001). The Spearman's correlation coefficient showed the gray ratios using both kits were positively correlated with the corneal fluorescein staining score (InflammaDry: ρ=0.48, P<0.05; domestic kit: ρ=0.52, P=0.003). Conclusion: The performances of the domestic and InflammaDry kits are consistent in the point-of-care assay for tear MMP-9, and the domestic kit has lower sensitivity but higher specificity.

Abstract
A novel optical fiber Vernier effect (VE) biosensor based on cascading Sagnac loops embedded with excessively tilted fiber grating (ExTFG) is proposed for the label free and specific detection of canine distemper virus (CDV). The VE was realized by cascading two different Sagnac loops with similar free spectrum range (FSR), one of which was integrated with panda-type polarization maintaining fiber (PMF) as the reference loop, and the other was embedded with ExTFG as the sensing loop. Owning to the amplified function of the VE, the refractive index (RI) sensitivity of the proposed sensing structure reached -1914.89 nm/RIU, which is approximately 12 times higher than that of the single ExTFG based RI sensor. Furthermore, the ExTFG in sensing loop was modified by graphene oxide (GO) and bio-functionalized by the CDV monoclonal antibodies (anti-CDV MAbs) for the specific detection of the CDV. Experimental results show that the proposed optical fiber Vernier sensor could detect the CDV in buffer solution with concentration as low as 1 pg/mL, and the sensitivity was about -1.18 nm/[log(mg/ml)] in the concentration range of 1 pg/mL ~ 50 ng/mL. The excellent specific and clinical properties of the biosensor were verified by immunoassays for fetal bovine serum, Toxoplasma gondii, rabies virus and CDV serum in sequence. Due to the sensitivity amplification function of VE, dense comb spectrum of the Sagnac loop and the stable interference spectra maintained by the polarized light, the proposed biosensor possesses the combined advantages of high sensitivity, high Q-factor and high stability, which may have potential applications in biosensing fields.

Abstract
Objective: To explore whether hsa_circ_0000670 promotes the progression of gastric cancer by regulating the miR-515-5p/SIX1 molecular axis. Methods: The gastric cancer and adjacent normal tissues of 35 gastric cancer patients admitted to Rugao Hospital Affiliated to Nantong University from 2014 to 2015 were collected. The expression levels of circ_0000670, miR-515-5p and Sine oculis homeobox 1 (SIX1) in gastric cancer tissues and cells were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. The correlations between circ_0000670 and miR-515-5p, miR-515-5p and SIX1, circ_0000670 and SIX1 were analyzed by the Pearson method. Patients were divided into low circ_0000670 expression group (17 cases) and high circ_0000670 expression group (18 cases) based on the median of circ_0000670 expression level, and Kaplan-Meier was used to analyze the 5-year survival of patients. Cell proliferation was assessed via clone formation assay. Cell cycle and apoptosis were detected by flow cytometry. Wound healing and Transwell assays were used to detect cell migration and invasion ability. The targeting relationship between miR-515-5p and circ_0000670 or SIX1 was confirmed by the dual luciferase reporter assay. Nude mice were injected into HGC-27 cells transfected with sh-NC or sh-circ_0000670, and the volume and weight of the transplanted tumor were measured, also, the levels of circ_0000670, miR-515-5p and SIX1 in the transplanted tumor tissue were detected. Results: The expression levels of circ_0000670 and SIX1 in gastric cancer tissues and cell lines were significantly increased (P<0.05), while the expression levels of miR-515-5p were significantly decreased (P<0.05). The survival rate of patients in the low circ_0000670 expression group (82.4%) was significantly higher than that in the high circ_0000670 expression group (28.7%, P=0.034). Circ_0000670 was negatively correlated with miR-515-5p (r=-0.846, P<0.001), and miR-515-5p was negatively correlated with SIX1 (r=-0.615, P<0.001), but circ_0000670 was positively correlated with SIX1 (r=0.814, P<0.001). Transfection of si-circ_0000670 or miR-515-5p mimic could significantly reduce the number of clone-forming cells, migration distance, migration and invasion cells (P<0.05), and increase the ratio of G(0)/G(1) phase cells, apoptosis rate and the protein level of E-cadherin (P<0.05), decreased the proportion of S-phase cells and the protein level of Vimentin (P<0.05). The dual luciferase report assay confirmed that circ_0000670 could target miR-515-5p, and miR-515-5p could bind to SIX1. Co-transfection of si-circ_0000670 and miR-515-5p inhibitor could significantly attenuate the effects of si-circ_0000670 on cell proliferation, migration, invasion, cell cycle and apoptosis (P<0.05). Co-transfection of miR-515-5p mimic and pcDNA-SIX1 could significantly reduce the effects of miR-515-5p mimic on cell proliferation, migration, invasion, cell cycle and apoptosis (P<0.05). Compared with the sh-NC group [volume=(596.20±125.46) mm(3) and weight=(538.00±114.39) g], the volume and weight of transplanted tumors in the sh-circ_0000670 group [volume=(299.20±47.58) mm 3 and weight=(289.80±48.73 g)] were significantly reduced (P<0.05), the expression levels of circ_0000670 and SIX1 were significantly reduced (P<0.05), and the expression level of miR-515-5p was significantly increased (P<0.05). Conclusion: Knockdown of circ_0000670 could inhibit cell proliferation, migration, invasion of gastric cancer cells, induce cell cycle arrest in G(0)/G(1) phase and promote cell apoptosis by regulating the miR-515-5p/SIX1 axis.

Abstract
In the repair of maxillofacial bone defects, autogenous craniofacial bone can often provide superior clinical results over long bone grafts. Most current studies have focused on the osteogenic differences between alveolar bone marrow (ABM) and long bone marrow (LBM), however, studies about the angiogenic differences between the two are currently lacking. We downloaded single-cell RNA sequencing (scRNA-seq) of mouse ABM and LBM respectively from the public database, and the data were processed by using Seurat package. CellphoneDB2 results showed that macrophages had the strongest interaction with mesenchymal stem cells (MSCs) and endothelial cells (ECs). ELISA results confirmed that ABM macrophages secreted a higher level of vascular endothelial growth factor A (Vegfa) compared to LBM macrophages, which further promoted angiogenesis of ECs and MSCs. Using SCENIC package, six key transcription factors (TFs) were identified to regulate the difference between ABM and LBM macrophages, and activating transcription factor 4 (Atf4) was confirmed to be more expressed in ABM macrophages by polymerase chain reaction (PCR) and western blot (WB), with predicted target genes including Vegfa. Besides, the result of scRNA-seq implied ABM macrophages more in M1 status than LBM macrophages, which was confirmed by the following experiments. From the results of another assay for transposase accessible chromatin sequencing (ATAC-seq) and RNA-seq about M1 macrophages, Atf4 was also confirmed to regulate the M1 polarization. So, we suspected that Atf4 regulated the different expression of Vegfa between ABM and LBM macrophages by activating M1 polarization. After knocking down Atf4, the expression of M1 polarization markers and Vegfa were downregulated and vasculogenic differences were eliminated, which were subsequently reversed by the addition of LPS/IFN-γ. Our study might provide a new idea to improve the success rate of autologous bone grafting and treatment of oral diseases.

Abstract
A formal [3 + 2] annulation reaction of crotonate-derived sulfur ylides and β-ketothioamides (KTAs) was successfully developed to produce good-to-excellent yields of thiazoline and spiro[indoline-3,3'-thiophene] scaffolds. This transformation is a powerful tool for the synthesis of thiazoline and spiro[indoline-3,3'-thiophene] scaffolds due to its mild reaction conditions, easily accessible starting materials, and broad substrate scope. A large-scale reaction was carried out to ensure the practical applicability of this methodology. Finally, the plausible mechanistic pathway of the developed methodology was investigated.

Abstract
BACKGROUND To explore the outcomes of mothers with Eisenmenger syndrome (ES) and their offspring. METHODS Pregnant women with ES admitted to the Beijing Anzhen Hospital between 2010 and 2019 were retrospectively analyzed and followed up. RESULTS Forty-two parturient women with ES were recruited, with an average age of 26.7 years (standard deviation [SD], ±4.0 years). The average gestational age was 33.7 weeks (SD, ±2.5 weeks). The average percutaneous oxygen saturation was 84.1 (±9.2), and 40 (95.2%) had caesarean delivery. The average pulmonary artery systolic pressure was 107.5 mmHg (SD, ±20.3 mmHg). Twelve (28.6%) women experienced pulmonary hypertensive crisis; 11 (26.2%) of these women died. Regarding the offspring, the average fetal weight was 1778.1 g (SD, ±555.3 g), six (14.3%) died, and congenital heart disease was diagnosed in three (7.1%). There were significant differences in age, gestational age, percutaneous oxygen saturation, Apgar score, and heart failure between the maternal death and non-death groups (P < 0.05). Death was mainly related to pulmonary hypertensive crisis and heart failure. CONCLUSIONS We recommend pregnancy termination if ES occurs during early pregnancy; however, patients should be informed of the risks if it occurs during late pregnancy. Multidisciplinary cooperation should be strengthened to improve the prognosis of the mothers and their offspring.

Abstract
Many clustering techniques have been proposed to group genes based on gene expression data. Among these methods, semi-supervised clustering techniques aim to improve clustering performance by incorporating supervisory information in the form of pairwise constraints. However, noisy constraints inevitably exist in the constraint set obtained on the practical unlabeled dataset, which degenerates the performance of semi-supervised clustering. Moreover, multiple information sources are not integrated into multi-source constraints to improve clustering quality. To this end, the research proposes a new multi-objective semi-supervised clustering algorithm based on constraints selection and multi-source constraints (MSC-CSMC) for unlabeled gene expression data. The proposed method first uses the gene expression data and the gene ontology (GO) that describes gene annotation information to form multi-source constraints. Then, the multi-source constraints are applied to the clustering by improving the constraint violation penalty weight in the semi-supervised clustering objective function. Furthermore, the constraints selection and cluster prototypes are put into the multi-objective evolutionary framework by adopting a mixed chromosome encoding strategy, which can select pairwise constraints suitable for clustering tasks through synergistic optimization to reduce the negative influence of noisy constraints. The proposed MSC-CSMC algorithm is testified using five benchmark gene expression datasets, and the results show that the proposed algorithm achieves superior performance.

Abstract
BACKGROUND Studies focused on pregnant women with congenital heart disease (CHD)-associated pulmonary hypertension (PH) are scarce and limited by small sample sizes and single-center design. This study sought to describe the pregnancy outcomes in women with CHD with and without PH. METHODS Outcomes for pregnant women with CHD were evaluated retrospectively from 1993 to 2016 and prospectively from 2017 to 2019 from 7 tertiary hospitals. PH was diagnosed on the basis of echocardiogram or catheterization. The incidence of maternal death, cardiac complications, and obstetric and offspring complications was compared for women with CHD and no PH, mild, and moderate-to-severe PH. RESULTS A total of 2220 pregnant women with CHD had completed pregnancies. PH associated with CHD was identified in 729 women, including 398 with mild PH (right ventricle to right atrium gradient 30-50 mm Hg) and 331 with moderate-to-severe PH (right ventricle to right atrium gradient >50 mm Hg). Maternal mortality occurred in 1 (0.1%), 0, and 19 (5.7%) women with CHD and no, mild, or moderate-to-severe PH, respectively. Of the 729 patients with PH, 619 (85%) had CHD-associated pulmonary arterial hypertension, and 110 (15%) had other forms of PH. Overall, patients with mild PH had better maternal outcomes than those with moderate-to-severe PH, including the incidence of maternal mortality or heart failure (7.8% versus 39.6%; P<0.001), other cardiac complications (9.0% versus 32.3%; P<0.001), and obstetric complications (5.3% versus 15.7%; P<0.001). Brain natriuretic peptide >100 ng/L (odds ratio, 1.9 [95% CI, 1.0-3.4], P=0.04) and New York Heart Association class III to IV (odds ratio, 2.9 [95% CI, 1.6-5.3], P<0.001) were independently associated with adverse maternal cardiac events in pregnancy with PH, whereas follow-up with a multidisciplinary team (odds ratio, 0.4 [95% CI, 0.2-0.6], P<0.001) and strict antenatal supervision (odds ratio, 0.5 [95% CI, 0.3-0.7], P=0.001) were protective. CONCLUSIONS Women with CHD-associated mild PH appear to have better outcomes compared with women with CHD-associated moderate-to-severe PH, and with event rates similar for most outcomes with women with CHD and no PH. Multimodality risk assessment, including PH severity, brain natriuretic peptide level, and New York Heart Association class, may be useful in risk stratification in pregnancy with PH. Follow-up with a multidisciplinary team and strict antenatal supervision during pregnancy may also help to mitigate the risk of adverse maternal cardiac events.

Abstract
In the pursuit of precision medicine for cancer, a promising step is to predict drug response based on data mining, which can provide clinical decision support for cancer patients. Although some machine learning methods for predicting drug response from genomic data already exist, most of them focus on point prediction, which cannot reveal the distribution of predicted results. In this paper, we propose a three-layer feature selection combined with a gamma distribution based GLM and a two-layer feature selection combined with an ANN. The two regression methods are applied to the Encyclopedia of Cancer Cell Lines (CCLE) and the Cancer Drug Sensitivity Genomics (GDSC) datasets. Using ten-fold cross-validation, our methods achieve higher accuracy on anticancer drug response prediction compared to existing methods, with an R 2 and RMSE of 0.87 and 0.53, respectively. Through data validation, the significance of assessing the reliability of predictions by predicting confidence intervals and its role in personalized medicine are illustrated. The correlation analysis of the genes selected from the three layers of features also shows the effectiveness of our proposed methods.

Abstract
Kiwifruit (Actinidia spp) is a woody, perennial and deciduous vine. In this genus, there are multiple ploidy levels but the main cultivated cultivars are polyploid. Despite the availability of many genomic resources in kiwifruit, SNP genotyping is still a challenge given these different levels of polyploidy. Recent advances in SNP array technologies have offered a high-throughput genotyping platform for genome-wide DNA polymorphisms. In this study, we developed a high-density SNP genotyping array to facilitate genetic studies and breeding applications in kiwifruit. SNP discovery was performed by genome-wide DNA sequencing of 40 kiwifruit genotypes. The identified SNPs were stringently filtered for sequence quality, predicted conversion performance and distribution over the available Actinidia chinensis genome. A total of 134 729 unique SNPs were put on the array. The array was evaluated by genotyping 400 kiwifruit individuals. We performed a multidimensional scaling analysis to assess the diversity of kiwifruit germplasm, showing that the array was effective to distinguish kiwifruit accessions. Using a tetraploid F1 population, we constructed an integrated linkage map covering 3060.9 cM across 29 linkage groups and performed QTL analysis for the sex locus that has been identified on Linkage Group 3 (LG3) in Actinidia arguta. Finally, our dataset presented evidence of tetrasomic inheritance with partial preferential pairing in A. arguta. In conclusion, we developed and evaluated a 135K SNP genotyping array for kiwifruit. It has the advantage of a comprehensive design that can be an effective tool in genetic studies and breeding applications in this high-value crop.

Abstract
Identification of structural connections between neurons is a prerequisite to understanding brain function. Here we developed a pipeline to systematically map brain-wide monosynaptic input connections to genetically defined neuronal populations using an optimized rabies tracing system. We used mouse visual cortex as the exemplar system and revealed quantitative target-specific, layer-specific and cell-class-specific differences in its presynaptic connectomes. The retrograde connectivity indicates the presence of ventral and dorsal visual streams and further reveals topographically organized and continuously varying subnetworks mediated by different higher visual areas. The visual cortex hierarchy can be derived from intracortical feedforward and feedback pathways mediated by upper-layer and lower-layer input neurons. We also identify a new role for layer 6 neurons in mediating reciprocal interhemispheric connections. This study expands our knowledge of the visual system connectomes and demonstrates that the pipeline can be scaled up to dissect connectivity of different cell populations across the mouse brain.

Abstract
Cardiovascular disease is a leading cause of morbidity and mortality in individuals with Down syndrome. Congenital heart disease is the most common cardiovascular condition in this group, present in up to 50% of people with Down syndrome and contributing to poor outcomes. Additional factors contributing to cardiovascular outcomes include pulmonary hypertension; coexistent pulmonary, endocrine, and metabolic diseases; and risk factors for atherosclerotic disease. Moreover, disparities in the cardiovascular care of people with Down syndrome compared with the general population, which vary across different geographies and health care systems, further contribute to cardiovascular mortality; this issue is often overlooked by the wider medical community. This review focuses on the diagnosis, prevalence, and management of cardiovascular disease encountered in people with Down syndrome and summarizes available evidence in 10 key areas relating to Down syndrome and cardiac disease, from prenatal diagnosis to disparities in care in areas of differing resource availability. All specialists and nonspecialist clinicians providing care for people with Down syndrome should be aware of best clinical practice in all aspects of care of this distinct population.

Abstract
Background Effective psychotherapy should satisfy the client, but that satisfaction depends on many factors. We do not fully understand the factors that affect client satisfaction with psychotherapy and how these factors synergistically affect a client's psychotherapy experience. Aims This study aims to use machine learning to predict Chinese clients' satisfaction with psychotherapy and analyze potential outcome contributors. Methods In this cross-sectional investigation, a self-compiled online questionnaire was delivered through the WeChat app. The information of 791 participants who had received psychotherapy was used in the study. A series of features, for example, the participants' demographic features and psychotherapy-related features, were chosen to distinguish between participants satisfied and dissatisfied with the psychotherapy they received. With our dataset, we trained seven supervised machine-learning-based algorithms to implement prediction models. Results Among the 791 participants, 619 (78.3%) reported being satisfied with the psychotherapy sessions that they received. The occupation of the clients, the location of psychotherapy, and the form of access to psychotherapy are the three most recognizable features that determined whether clients are satisfied with psychotherapy. The machine-learning model based on the CatBoost achieved the highest prediction performance in classifying satisfied and psychotherapy clients with an F1 score of 0.758. Conclusion This study clarified the factors related to clients' satisfaction with psychotherapy, and the machine-learning-based classifier accurately distinguished clients who were satisfied or unsatisfied with psychotherapy. These results will help provide better psychotherapy strategies for specific clients, so they may achieve better therapeutic outcomes.

Abstract
OBJECTIVES Dietary Approaches to Stop Hypertension (DASH) pattern has been found to aid in the reduction of obesity, oxidative stress, and chronic inflammation, which are all strongly linked to the development of head and neck cancer (HNC). Nevertheless, no epidemiological studies have investigated the association between this dietary pattern and HNC risk. This study was conducted with the purpose of bridging this gap in knowledge. DESIGN A prospective cohort study involving 98,459 American adults aged 55 years and older. SETTING AND PARTICIPANTS Data were drawn from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Trial. In the present study, participants with dependable energy intake data who furnished baseline and dietary history information were identified as the study population. METHODS Diet was assessed by food frequency questionnaires and the DASH score was calculated to assess each participant's adherence to DASH eating pattern. Cox proportional hazards models were used to calculate multivariable adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the occurrence of HNC. To visualize the variation in cancer risk for HNC and its subtypes across the entire spectrum of DASH scores, restricted cubic spline plots were utilized. Additionally, a series of predefined subgroup analyses were performed to identify potential effect modifiers, and several sensitivity analyses were conducted to assess the stability of the findings. RESULTS During a follow-up period of 871,879.6 person-years, 268 cases of HNC were identified, comprising 161 cases pertaining to oral cavity and pharynx cancers, as well as 96 cases of larynx cancer. In the fully adjusted model, adherence to the DASH diet was associated with a remarkable 57% reduction in the risk of HNC when comparing extreme quartiles (HR quartile 4 vs 1: 0.43; 95% CI: 0.28, 0.66; P for trend < 0.001). The restricted cubic spline plots demonstrated a linear dose-response relationship between the DASH score and the risk of HNC as well as its subtypes. Subgroup analysis revealed that the protective effect of the DASH diet against HNC was particularly pronounced in individuals with lower daily energy intake. The primary association remained robust in the sensitivity analysis. CONCLUSIONS In American middle-aged and older population, adherence to the DASH diet may help prevent HNC, particularly for individuals with lower daily energy intake.

Abstract
In large areas of the ocean, iron concentrations are insufficient to promote phytoplankton growth. Numerous studies have been conducted to characterize the effect of iron on algae and how algae cope with fluctuating iron concentrations. Fertilization experiments in low-iron areas resulted primarily in diatom-dominated algal blooms, leading to laboratory studies on diatoms comparing low- and high-iron conditions. Here, we focus on the short-term temporal response following iron addition to an iron-starved open ocean diatom, Thalassiosira oceanica. We employed the NanoString platform and analyzed a high-resolution time series on 54 transcripts encoding proteins involved in photosynthesis, N-linked glycosylation, iron transport, as well as transcription factors. Nine transcripts were iron-responsive, with an immediate response to the addition of iron. The fastest response observed was the decrease in transcript levels of proteins involved in iron uptake, followed by an increase in transcript levels of iron-containing enzymes and a simultaneous decrease in the transcript levels of their iron-free replacement enzymes. The transcription inhibitor actinomycin D was used to understand the underlying mechanisms of the decrease of the iron-responsive transcripts and to determine their half-lives. Here, Mn-superoxide dismutase (Mn-SOD), plastocyanin (PETE), ferredoxin (PETF) and cellular repressor of EA1-stimulated genes (CREGx2) revealed longer than average half-lives. Four iron-responsive transcripts showed statistically significant differences in their decay rates between the iron-recovery samples and the actD treatment. These differences suggest regulatory mechanisms influencing gene transcription and mRNA stability. Overall, our study contributes towards a detailed understanding of diatom cell biology in the context of iron fertilization response and provides important observations to assess oceanic diatom responses following sudden changes in iron concentrations.

Abstract
Crystal malt, the most popular type of specialty malt used in beer brewing, plays a vital role in forming complex flavor and color. Nevertheless, crystal malt is only defined based on the malting process, and there is not any standard to evaluate its quality. In the current study, the volatile aroma constituents of commercial crystal malt samples were analyzed with headspace solid-phase microextraction combined with gas chromatography-mass spectrometry, in order to explore the characteristic aroma compounds of crystal malt. The average concentration of volatile aroma compounds in 10 crystal malt samples is 587 µg L-1 , ranging from 347 to 1265 µg L-1 . A total of 38 aroma compounds were identified, 47% of which were existed in all the 10 samples. Based on principal component analysis and odor activity value, isobutyraldehyde, 2-methylbutanal, furfural, 2-acetyl-1H-pyrrole, oct-1-en-3-ol, 4-methyl-2-phenyl-2-pentenal, and (2E)-2-isopropyl-5-methyl-2-hexenal could be considered the characteristic aroma compounds of crystal malt. The results of this present study would help to establish a standard to assess the quality traits of crystal malt sample.

Abstract
Hearts with double outlet ventricles and concordant atrioventricular connections account for about 1%–3% of all cases of congenital heart disease. We review hearts with two ventricles and concordant atrioventricular connections with double outlet right ventricle (DORV), double outlet left ventricle (DOLV) and double outlet both ventricles (DOBV) from the morphological and clinical imaging perspectives. These hearts are a heterogeneous group of congenital cardiac malformations with a wide range of pathophysiologies that require an individualised surgical approach based on a precise understanding of the complex cardiovascular anatomy. Owing to their differing temporal, spatial and contrast resolutions, we propose that multimodality imaging provides optimal characterisation of various intracardiac morphological features of double outlet hearts. This approach aids clinical diagnosis for optimising treatment options across these malformations.

Abstract
Sunburn is one of the most common skin lesions caused by excessive UV exposure, and its incidence is highly correlated with the risks of skin cancer. A variety of drugs including corticosteroids and NSAIDs have been developed to treat acute sunburn, however, they have raised severe concerns such as poor healing efficacy and long recovery time. We have for the first time extracted non-denatured type I collagen from yak hide, which displays a canonical triple helical structure with melting temperature of 42.7 °C. The highly pure yak collagen type I (YCI) self-assembles to form well-ordered nanofibers with periodic d-bands. YCI is highly biocompatible, and it significantly promotes the proliferation and adhesion of HFF-1 cells. The sunburn healing effects of YCI has been investigated using acute skin injury mouse model. Histological analysis shows that 4 days' treatment of YCI has resulted in the recovery of sunburned mice skin to a healthy state, indicated by pronounced acceleration of epithelization and collagen deposition. The collagen volume fraction as well as the hydroxyproline (Hyp) content of YCI-treated sunburned skin have been found to be greatly increased, confirming the enhanced regeneration of collagen. YCI creams and dressings have also shown superior healing capacity of sunburn by remarkably shortening the recovery time. Notably, the denatured collagen-targeted staining results indicated a large quantity of denatured collagen in sunburned mice, which became substantially reduced after the YCI treatment. FITC-labeled YCI has been further found to penetrate into the dermis of sunburned mice. The highly biocompatible and bioactive non-denatured YCI provides an improved treatment of sunburn, indicating very promising applications of YCI in cosmetics and dermatology.

Abstract
BACKGROUND World Health Organization (WHO) group 1 pulmonary arterial hypertension (PAH) is a progressive, debilitating disease. Previous observational studies have demonstrated that pulmonary artery denervation (PADN) reduces pulmonary artery pressures in PAH. However, the safety and effectiveness of PADN have not been established in a randomized trial. OBJECTIVES The aim of this study was to determine the treatment effects of PADN in patients with group 1 PAH. METHODS Patients with WHO group 1 PAH not taking PAH-specific drugs for at least 30 days were enrolled in a multicenter, sham-controlled, single-blind, randomized trial. Patients were assigned to receive PADN plus a phosphodiesterase-5 inhibitor or a sham procedure plus a phosphodiesterase-5 inhibitor. The primary endpoint was the between-group difference in the change in 6-minute walk distance from baseline to 6 months. RESULTS Among 128 randomized patients, those treated with PADN compared with sham had a greater improvement in 6-minute walk distance from baseline to 6 months (mean adjusted between-group difference 33.8 m; 95% CI: 16.7-50.9 m; P < 0.001). From baseline to 6 months, pulmonary vascular resistance was reduced by -3.0 ± 0.3 WU after PADN and -1.9 ± 0.3 WU after sham (adjusted difference -1.4; 95% CI: -2.6 to -0.2). PADN also improved right ventricular function, reduced tricuspid regurgitation, and decreased N-terminal pro-brain natriuretic peptide. Clinical worsening was less (1.6% vs 13.8%; OR: 0.11; 95% CI: 0.01-0.87), and a satisfactory clinical response was greater (57.1% vs 32.3%; OR: 2.79; 95% CI: 1.37-5.82) with PADN treatment during 6-month follow-up. CONCLUSIONS In patients with WHO group 1 PAH, PADN improved exercise capacity, hemodynamic status, and clinical outcomes during 6-month follow-up.

Abstract
OBJECTIVE The results of PD-1/PD-L1 inhibitor combined with chemotherapy for TNBC are controversial. Therefore, a meta-analysis was conducted to evaluate the efficacy and safety after PD-1/PD-L1 inhibitors plus chemotherapy in TNBC patients. METHODS We systematically searched seven databases and several mainly oncology conferences for prospective clinical trials of chemotherapy combined with immunotherapy to treat TNBC, and we included pathologic complete response (PCR), progression-free survival (PFS), overall survival (OS) and adverse effects as outcome indicators of the study. RESULTS We analyzed data from six studies involving 4,187 patients. The efficacy analysis indicated that PD1/PD-L1 inhibitor combined with chemotherapy significantly increased PCR rates in neoadjuvant patients (OR: 1.60; 95% CI: 1.18-2.17; p=0.003). There was no correlation between increases in PCR rates and the expression of PD-L1, but the PCR rate was higher in PD-L1+ patients. Subgroup analysis suggested that the lymph node-positive (OR: 2.52; 95% CI: 1.69-3.77; p<0.001) and ECOG PS 0 (OR: 1.9; 95% CI: 1.42-2.53; p<0.001) subgroups benefited from the combination of PD-1/PD-L1 inhibitor plus chemotherapy. In TNBC receiving advanced rescue treatment, PFS was higher in the group receiving PD-1/PD-L1 inhibitor plus chemotherapy than in the group receiving chemotherapy alone (HR: 0.78; 95% CI: 0.70-0.86; p<0.001). Compared with chemotherapy alone, PD-1/PD-L1 inhibitors combined with chemotherapy did not increase the OS of patients (HR=0.88, 95% CI: 0.76~1.03, p=0.12). In addition, the toxicity analysis showed that more grade 3-4 adverse effects and severe adverse effects occurred in the PD-1/PD-L1 inhibitor combined with chemotherapy group. CONCLUSIONS PD-1/PD-L1 inhibitors combined with chemotherapy can improve the PCR and PFS rate of TNBC patients, but did not improve the OS, and had a higher risk of AEs.

Abstract
Microalgae harvest and lipid accumulation were important factors influencing commercialized development of microalgae biodiesel. Spontaneous flocculation was an ideal method in microalgae harvest, but few rich lipid microalgae could be harvested by spontaneous flocculation. Rich lipid alga Heveochlorella sp. Yu has a characteristic of spontaneous flocculation to be harvested. Heveochlorella sp. Yu has high lipid productivity (105.24 mg L-1 d-1) and fine spontaneous flocculation efficiency (82.93 %, 2 h) on early stationary phase (day 9). The polysaccharides consisting of glucose, mannose, galactose, rhamnose and fructose (8.67:4.90:3.27:2.16:1) in loose-bound extracellular polymeric substance (LB-EPS) might make great contribution in microalgae flocculation. Meanwhile, the zeta potential close to zero was also beneficial to microalgae flocculation. Besides, the adhesion free energy related with cells adhesion was detected by thermomechanical analysis. Afterward, Extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory was utilized to quantitatively evaluate short-range interactions involved in the spontaneous aggregation among cells. Collectively, biophysical analyses indicated that content and composition of EPS, Zeta potential, thermodynamic parameter and total interaction based on XDLVO theory were closely connected with spontaneous flocculation in microalga Yu. Our study provided a harvest-simplified process of rich microalgae, which proposes a new idea for commercial development of microalgae biodiesel.

Abstract
Objective: To examine the association of body mass index (BMI) and waist circumference (WC) with frailty among oldest-old adults in China. Methods: A total of 7 987 people aged 80 years and older (oldest-old) who participated in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2017-2018 were included. Information on demographic characteristics, behavior pattern, diet, activities of daily living, cognitive function, health status, disease condition were collected by questionnaire and physical examination. Generalized linear mixed model and restricted cubic splines (RCS) were used to analyze the association of BMI and WC with frailty. Results: The mean age of all participants was 91.7 years, and their mean BMI and WC were (21.3±3.5) kg/m2 and (82.9±10.5) cm, respectively. The proportion of male was 42.3% (3 377/7 987), and the proportion of people with frailty was 33.7% (2 664/7 987). After controlling confounding factors, compared with T2 (19.1-22.1 kg/m2) of BMI, the OR (95%CI) of the female T1 (<19.1 kg/m2) and T3 (≥22.2 kg/m2) group was 1.39 (1.17-1.65) and 1.27 (1.07-1.52), respectively. Compared with T2 (77-85 cm) of WC, the OR (95%CI) of female T1 (<77 cm) and T3 (≥86 cm) group was 1.20 (1.01-1.42) and 1.10 (0.93-1.31), respectively. The results of multiple linear regression model with restrictive cubic spline showed that there was a non-linear association of BMI and WC with frailty in female. Conclusion: There is a U-shaped association of BMI and WC with frailty in female participants.

Abstract
A highly sensitive optical fiber Mach-Zehnder interference curvature sensor based on MMF-GIMMF-MMF, which was made by sandwiching the graded-index multimode fiber (GIMMF) between two pieces of very short stepped-index multimode fibers (SIMMFs) spliced with input-single-mode fiber (SMF) and output-SMF, respectively, was proposed. The core diameter of the SIMMFs and GIMMF was 105 µm and 50 µm, respectively, and cladding diameter of them were both 125 µm. The sensing principle of the MMF-GIMMF- MMF sensors and the influences of structure parameters on the interference spectrum characteristics were theoretically analyzed in detail. Experimental results showed that when the length of the GIMMF was short enough (usually ≤ 10 mm), interference spectrum was induced by the interaction between the core modes and the low-order cladding modes due to the special structure of the designed Mach-Zehnder interferometer. Intensity of the interference valleys was highly sensitive to the applied bending but nearly independent of the surrounding temperature, on the contrary, the dip wavelength showed negligible sensitivity to the applied bending but relatively high temperature sensitivity. Thus, a temperature- independent curvature sensor could be realized by tracing the intensity variation of interference valley. In addition, different interference valley exhibited different intensity-based curvature sensitivity, providing more options for curvature sensing applications. Especially, total length of the sensor could be as short as 3 mm with length of GIMMF and SIMMFs only 1mm, the maximum curvature sensitivity could reach up to -78.75 dB/m-1 in the small curvature range of 0-2.36 m-1. Owing to its compact size, easy fabrication, good reproducibility and low cost, the proposed sensor is promising for bending-related high-precision engineering applications.

Abstract
To assess the long-term prognostic value of cardiac catheterization and acute vasodilator testing (AVT) with inhaled iloprost in children with idiopathic pulmonary arterial hypertension (IPAH). Data on 81 consecutive children with IPAH referred to our center who underwent cardiac catheterization and AVT between June 2008 and August 2019 were collected. The correlation between the invasive hemodynamic data and transplant-free survival was analyzed. Twenty-four patients died and 1 underwent lung transplantation during a median follow-up of 3.8 years, with a 5-year transplant-free survival rate of 64.9%. Univariate analysis showed that predictors associated with improved survival included a lower pulmonary vascular resistance index (PVRI), PVRI/systemic vascular resistance index (SVRI), mean pulmonary arterial pressure (mPAP)/mean systemic arterial pressure, mean right atrial pressure, and a higher cardiac index (CI), mixed systemic venous oxygen saturations (SvO2), and acute vasodilator response (AVR) according to the Barst criteria (decrease in mPAP and PVRI/SVRI ratio of >20% without a decrease in CI). In multivariate Cox regression analysis, Barst AVR and SvO2 were independently related to transplant-free survival. Multiple hemodynamic variables from cardiac catheterization and AVT with inhaled iloprost have important prognostic value for long-term survival in children with IPAH, of which pulmonary vasoreactivity defined by the Barst criteria and SvO2 are independent prognostic factors.

Abstract
The positive treatment outcomes of low frequency (LF) repetitive transcranial magnetic stimulation (rTMS) when applied over the right dorsolateral prefrontal cortex (DLPFC) in treatment-refractory depression has been verified. However, the mechanism of action behind these results have not been well-explored. In this work we used simultaneous functional magnetic resonance imaging (fMRI) during TMS to explore the effect of LF rTMS on brain activity when applied to the right [RDLPFC1 (MNI: 50, 30, 36)] and left DLPFC sites [LDLPFC1 (MNI: -50, 30, 36), LDLPFC2 (MNI: -41, 16, 54)]. Seventeen healthy adult volunteers participated in this study. To identify brain areas affected by rTMS, an independent component analysis and a general linear model were used. Our results showed an important laterality effect when contrasting rTMS over the left and right sites. Specifically, LF rTMS increased brain activity at the striatum, thalamus, and areas of the default mode network when applied to the right, but not to the contralateral left DLPFC. In contrast, no site differences were observed when evaluating the effect of LF rTMS over the two left sites. These findings demonstrate that LF rTMS to the right DLPFC was able to stimulate the cortico-striato-thalamo-cortical pathway, which is dysregulated in patients with major depressive disorder; therefore, possibly providing some neurobiological justification for the successful outcomes found thus far for LF rTMS in the treatment of depression.

Abstract
Organismal traits can evolve in a coordinated way, with correlated patterns of gains and losses reflecting important evolutionary associations. Discovering these associations can reveal important information about the functional and ecological linkages among traits. Phylogenetic profiles treat individual genes as traits distributed across sets of genomes and can provide a fine-grained view of the genetic underpinnings of evolutionary processes in a set of genomes. Phylogenetic profiling has been used to identify genes that are functionally linked, and to identify common patterns of lateral gene transfer in microorganisms. However, comparative analysis of phylogenetic profiles and other trait distributions should take into account the phylogenetic relationships among the organisms under consideration. Here we propose the Community Coevolution Model (CCM), a new coevolutionary model to analyze the evolutionary associations among traits, with a focus on phylogenetic profiles. In the CCM, traits are considered to evolve as a community with interactions, and the transition rate for each trait depends on the current states of other traits. Surpassing other comparative methods for pairwise trait analysis, CCM has the additional advantage of being able to examine multiple traits as a community to reveal more dependency relationships. We also develop a simulation procedure to generate phylogenetic profiles with correlated evolutionary patterns that can be used as benchmark data for evaluation purposes. A simulation study demonstrates that CCM is more accurate than other methods including the Jaccard Index and three tree-aware methods. The parameterization of CCM makes the interpretation of the relations between genes more direct, which leads to Darwin's scenario being identified easily based on the estimated parameters. We show that CCM is more efficient and fits real data better than other methods resulting in higher likelihood scores with fewer parameters. An examination of 3786 phylogenetic profiles across a set of 659 bacterial genomes highlights linkages between genes with common functions, including many patterns that would not have been identified under a non-phylogenetic model of common distribution. We also applied the CCM to 44 proteins in the well-studied Mitochondrial Respiratory Complex I and recovered associations that mapped well onto the structural associations that exist in the complex.
