Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is a pulmonary vascular disease characterized by an insidious onset, progressive deterioration, and poor prognosis. It is distinguished by the thrombotic organization within the pulmonary arteries, leading to vascular stenosis or occlusion. This results in a progressive increase in pulmonary vascular resistance and pulmonary arterial pressure, ultimately leading to right heart failure. In recent years, balloon pulmonary angioplasty (BPA) has emerged as an effective treatment option for patients ineligible for pulmonary endarterectomy (PEA). However, the use of stents in patients with suboptimal balloon dilation remains controversial. This article describes two cases of chronic thromboembolic pulmonary hypertension (CTEPH) in which balloon angioplasty yielded unsatisfactory results, subsequently leading to stent placement. Following stent implantation, there was improved blood flow, significant reduction in pulmonary arterial pressure, and notable alleviation of patient symptoms. One-year follow-up showed no recurrence of stenosis within the stent, suggesting potential guidance for the use of pulmonary artery stenting as a treatment modality for CTEPH. This report provided new insights into the therapeutic approach for CTEPH.

Worldwide forest surveys reveal forty-three new species in Phytophthora major Clade 2 with fundamental implications for the evolution and biogeography of the genus and global plant biosecurity. Stud Mycol 2024; 107:251-388. [PMID: 38600961 PMCID: PMC11003442 DOI: 10.3114/sim.2024.107.04] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 01/15/2024] [Indexed: 04/12/2024] Open
Abstract
During 25 surveys of global Phytophthora diversity, conducted between 1998 and 2020, 43 new species were detected in natural ecosystems and, occasionally, in nurseries and outplantings in Europe, Southeast and East Asia and the Americas. Based on a multigene phylogeny of nine nuclear and four mitochondrial gene regions they were assigned to five of the six known subclades, 2a-c, e and f, of Phytophthora major Clade 2 and the new subclade 2g. The evolutionary history of the Clade appears to have involved the pre-Gondwanan divergence of three extant subclades, 2c, 2e and 2f, all having disjunct natural distributions on separate continents and comprising species with a soilborne and aquatic lifestyle and, in addition, a few partially aerial species in Clade 2c; and the post-Gondwanan evolution of subclades 2a and 2g in Southeast/East Asia and 2b in South America, respectively, from their common ancestor. Species in Clade 2g are soilborne whereas Clade 2b comprises both soil-inhabiting and aerial species. Clade 2a has evolved further towards an aerial lifestyle comprising only species which are predominantly or partially airborne. Based on high nuclear heterozygosity levels ca. 38 % of the taxa in Clades 2a and 2b could be some form of hybrid, and the hybridity may be favoured by an A1/A2 breeding system and an aerial life style. Circumstantial evidence suggests the now 93 described species and informally designated taxa in Clade 2 result from both allopatric non-adaptive and sympatric adaptive radiations. They represent most morphological and physiological characters, breeding systems, lifestyles and forms of host specialism found across the Phytophthora clades as a whole, demonstrating the strong biological cohesiveness of the genus. The finding of 43 previously unknown species from a single Phytophthora clade highlight a critical lack of information on the scale of the unknown pathogen threats to forests and natural ecosystems, underlining the risk of basing plant biosecurity protocols mainly on lists of named organisms. More surveys in natural ecosystems of yet unsurveyed regions in Africa, Asia, Central and South America are needed to unveil the full diversity of the clade and the factors driving diversity, speciation and adaptation in Phytophthora.

The cGAS-STING pathway in viral infections: a promising link between inflammation, oxidative stress and autophagy. Front Immunol 2024; 15:1352479.

Abstract
The host defence responses play vital roles in viral infection and are regulated by complex interactive networks. The host immune system recognizes viral pathogens through the interaction of pattern-recognition receptors (PRRs) with pathogen-associated molecular patterns (PAMPs). As a PRR mainly in the cytoplasm, cyclic GMP-AMP synthase (cGAS) senses and binds virus DNA and subsequently activates stimulator of interferon genes (STING) to trigger a series of intracellular signalling cascades to defend against invading pathogenic microorganisms. Integrated omic and functional analyses identify the cGAS-STING pathway regulating various host cellular responses and controlling viral infections. Aside from its most common function in regulating inflammation and type I interferon, a growing body of evidence suggests that the cGAS-STING signalling axis is closely associated with a series of cellular responses, such as oxidative stress, autophagy, and endoplasmic reticulum stress, which have major impacts on physiological homeostasis. Interestingly, these host cellular responses play dual roles in the regulation of the cGAS-STING signalling axis and the clearance of viruses. Here, we outline recent insights into cGAS-STING in regulating type I interferon, inflammation, oxidative stress, autophagy and endoplasmic reticulum stress and discuss their interactions with viral infections. A detailed understanding of the cGAS-STING-mediated potential antiviral effects contributes to revealing the pathogenesis of certain viruses and sheds light on effective solutions for antiviral therapy.

Abstract
Pancreaticopleural fistula (PPF) is a rare but serious complication caused by pancreatic lesions that presents primarily with respiratory tract symptoms and pleural effusion. We report a paediatric case of PPF without any respiratory symptoms throughout the course of the disease, including cough or shortness of breath, with only a bulging chest as the first symptom. Imaging revealed a large left pleural effusion and Magnetic Resonance Cholangiopancreatography (MRCP) revealed a fistula formed between the pancreatic tail and the pleural cavity, which penetrated the diaphragm and opened in the central tendon of the diaphragm. The patient eventually underwent resection of the pancreatic tail lesion and repair of the diaphragmatic fistula and recovered soon thereafter.

Abstract
Pulmonary tumor thrombotic microangiopathy is a malignancy-related complication with rapid progression and high mortality. To improve the understanding of the disease, early diagnosis and treatment are key to successful treatment. A 39-year-old patient with pulmonary hypertension transferred from another hospital was admitted to the First Affiliated Hospital of Guangzhou Medical University on September 26, 2021. The patient developed shortness of breath and progressive exacerbation over the past month. No pulmonary artery embolism was seen on computed tomography pulmonary angiography (CTPA) at the outside hospital where the breast cancer was diagnosed. Pulmonary tumor thrombotic microangiopathy was immediately considered on admission and oncological endocrine therapy was started. After treatment, the patient's dyspnoea improved, PET-CT showed significant tumor regression, and cardiac ultrasound showed a significant decrease in pulmonary artery pressure. The successful treatment experience of this case was summarized for reference.

Radiomics signature based on CECT for non-invasive prediction of response to anti-PD-1 therapy in patients with hepatocellular carcinoma. Clin Radiol 2023; 78:e37-e44. [PMID: 36257868 DOI: 10.1016/j.crad.2022.09.113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Revised: 08/07/2022] [Accepted: 09/02/2022] [Indexed: 01/18/2023]
Abstract
PURPOSE This study aimed to develop a radiomics signature (RS) based on contrast-enhanced computed tomography (CECT) and evaluate its potential predictive value in hepatocellular carcinoma (HCC) patients receiving anti-PD-1 therapy. METHOD CECT scans of 76 HCC patients who received anti-PD-1 therapy were obtained in this study (training group = 53 and validation group = 23). The least absolute shrinkage and selection operator (LASSO) regression was applied to select radiomics features of primary and metastatic lesions and establish a RS to predict lesion-level response. Then, a nomogram combined the mean RS (MRS) and clinical variables with patient-level response as the end point. RESULTS In the lesion-level analysis, the area under the curves (AUCs) of RS in the training and validation groups were 0.751 (95% CI, 0.668-0.835) and 0.734 (95% CI, 0.604-0.864), respectively. In the patient-level analysis, the AUCs of the nomogram in the training and validation groups were 0.897 (95% CI, 0.798-0.996) and 0.889 (95% CI, 0.748-1.000), respectively. The nomogram stratified patients into low- and high-risk groups, which showed a significant difference in progression-free survival (PFS) (p<0.05). CONCLUSIONS The RS is a noninvasive biomarker for predicting anti-PD-1 therapy response in patients with HCC. The nomogram may be of clinical use for identifying high-risk patients and formulating individualised treatments.

Introduction
Selexipag is an oral selective prostacyclin IP receptor agonist indicated for treatment of pulmonary arterial hypertension (PAH). Data on its real-world safety and efficacy in Asians is lacking.
Purpose
We sought to evaluate the clinical characteristics, treatment regimens and outcomes of patients initiated on selexipag in a tertiary cardiac centre in Asia.
Methods
This was a retrospective study on all patients initiated on selexipag from January 2017 to December 2020. Baseline and follow up characteristics including demographics, functional status and clinical data were collected. Clinical outcomes evaluated included hospitalisation for PH related complications and all-cause mortality. Patients were risk stratified using the COMPERA 2.0 risk scores.
Results
A total of 36 PAH patients were treated with selexipag. At baseline, most patients were WHO functional class II or III (36.4% and 51.5% respectively), with a NT-proBNP of 1335 pg/ml (557 – 2918) and 6 minute walk test (6MWT) duration of 327.5 ±126.4 meters. Selexipag was initiated at 200mcg twice daily dosage for all except one patient (started at 200mcg once daily) and the maximum tolerated dose ranged from 200mcg twice daily to 1400mcg twice daily, with majority tolerating up to a dose of 600mcg twice daily (58.3%). Side effects were reported in 23 patients (63.9%), of which headache (27.8%), diarrhea (30.6%) or musculoskeletal symptoms (27.8%) were predominant. After a median follow up duration of 25.9 ± 23.1 months, selexipag was stopped in 20 patients (55.6%), of which eight patients were due to PAH progression requiring alternative therapy, and 12 patients due to side effects from selexipag. At baseline, patients were classified into low (8.3%), intermediate-low (30.6%), intermediate-high (33.3%) and high risk (27.8%) respectively. Patients who continued on selexipag at follow up showed no change (46.2%), improvement (15.4%) and deterioration (38.5%) in risk score. In the overall cohort of 36 patients, majority (75%) had at least one hospitalisation for PAH related complications and 15 patients (41.7%) demised.
Conclusion
In this real-world study, while selexipag was associated with a stable or improved PAH risk scores in majority of patients, there was a subset of patients with disease progression or intolerance to the medication. Further studies are warranted to identify patients who will benefit most from this therapy.

Abstract
Abstract
Introduction
Fibrofatty plaque burden (FFB) is a high-risk, vulnerable plaque feature comprised of an atheromatous core and fibrous cap with increased risk of coronary artery disease (CAD) [1]. Psoriasis (PSO) is a chronic inflammatory disease linked with atherosclerotic risk and premature cardiovascular disease, driven in part by vulnerable plaque rupture [2,3]. Machine learning (ML) previously showed the prognostic value of FFB in predicting 5-year risk of cardiac-related mortality in patients with CAD [4]. Whether ML can predict FFB in psoriasis is understudied.
Purpose
To use ML to identify top determinants of FFB by CCTA in PSO.
Methods
320 consecutive participants with psoriasis were recruited as part of an ongoing cohort study, of whom 307 had FFB analyzed with coronary computed tomography angiography (CCTA) and quantified by QAngio CT (Medis, The Netherlands). 140 out of 182 potential determinants were subjected to ML algorithms analyzed by random forest and validated by 5-fold cross validation to select the top determinants based on R-square criteria. Lipid concentration and size were measured by nuclear magnetic resonance (NMR) and sdLDL-C was calculated by Sampson's formula.
Results
The top 21 determinants of FFB at baseline were grouped into 3 categories: cardiometabolic risk factors (BMI, sex, DBP, mean arterial pressure, exercise, heart rate, glucose, anxiety, psoriasis disease duration), clinical measurements (basophils, platelets, hemoglobin, RBC, alkaline phosphatase, ALT, creatinine, neutrophil-to-lymphocyte ratio), and lipoproteins (LDL particle size, apolipoprotein A1, apolipoprotein B-to-A1 ratio, calculated sdLDL-C).
Conclusion
ML confirmed that FFB strongly correlates with cardiometabolic risk factors, clinical measurements, and lipoproteins. Further investigations into these top determinants of FFB over time may provide insight into potential therapeutic interventions that decrease cardiovascular risk in patients with chronic inflammatory diseases and should be validated in larger studies.

Abstract
OBJECTIVE To observe the effects of minimally invasive surgical repair of pectus excavatum (NUSS) on the degree of chest flatness, cardiopulmonary function, and bone metabolism indexes in children of various age groups. METHODS In this retrospective study, 62 children with pectus excavatum admitted to our hospital were divided into two groups: group A (3-12 years old) and group B (>12 years old), with 31 cases in each group. All of them were treated with NUSS. The treatment effectiveness, perioperative indexes (operation time, blood loss, ground time, and hospitalization time), degree of chest flatness, cardiopulmonary function, bone metabolism indicators, and complications were compared between the two groups. RESULTS There was no significant difference between patients in the two groups in terms of operation time, blood loss, ground time, and hospitalization time (all P>0.05). The overall response rate to treatment in group A (93.55%) was higher than that of group B (70.97%; P<0.05). Three months after the operation, the chest flatness as well as serum alkaline phosphatase and its bone isoform levels in both groups were decreased, while left ventricular ejection fraction, cardiac index, stroke volume, FEV1, and peak expiratory flow levels were increased compared to before the operation, and the improvement in the above indicators of group A was better than Group B (all P<0.05). There was no significant difference in the incidence of complications between the two groups (16.13% vs. 9.68%; P>0.05). CONCLUSION NUSS surgery can achieve satisfactory results in treating children with pectus excavatum at different ages. However, in a certain age range, a younger age indicates a better effect. NUSS procedure effectively improves postoperative flat chest, cardiopulmonary function, and bone metabolism indexes.

Abstract
BackgroundPsoriasis (PsO) and musculoskeletal manifestations are common among patients with psoriatic arthritis (PsA). A shared-care model between rheumatologists and dermatologists has been advocated to promote early diagnosis and improve management care. Data from Asia is scanty. Patients’ and learners’ experience of shared-care models are seldom explored.ObjectivesWe described the set-up of a new shared-cared PsA-PsO clinic incorporating service, education and research between rheumatologist and dermatologist for PsA. We describe the patients’ and learners’ experience of this shared-care model.MethodsA combined care clinic was newly set up in 2019. Referrals were internal through either specialty. Each patient was first seen by a trainee, followed by both a dermatologist and rheumatologist simultaneously in the same consultation room. We collected patients’ and learners’ experience through self-administered survey.ResultsFrom May 2019 to January 2020, data from 44 visits (55% new referrals, 45% follow-up) from 28 patients were captured in the PsA-PsO clinic. 50% of cases were referred from either specialty. 34% were referred for diagnostic doubts, 66% were for therapeutic issues. 61% of patients continued follow-up in the PsA-PsO clinic, and 39% discharged back to respective care. From patients’ experience rated on scale from 0-10, median (interquartile range, IQR) rating of the care was 8 (7, 8). 69.2% and 96% of patients would recommend the care to others. Free text comments included enhanced convenience, time saving, and having both specialties input on management. From 20 learners (3 medial students, 12 residents, 4 senior residents and one scientist), 95% reported extremely or very beneficial to training, 77.8% reported improved confidence in care for PsA and/or PsO patients. The PsA-PsO clinic was temporally suspended during the Covid-19 viral pandemic since February 2020 due to lack of manpower and not fulfilling the spacing out requirement for infectious control. The service was resumed gradually from May 2021.ConclusionDespite challenges, we report the setup of a new care model between dermatologists and rheumatologists for care of patients with psoriatic disease. The care model was well received by patients. Learners from various levels reported benefit from the learning experience.Disclosure of InterestsCassandra Hong: None declared, Liwen Fang: None declared, Yi-Wei Yeo: None declared, Haur Yueh Lee: None declared, Andrea Low: None declared, Ying Ying Leung Speakers bureau: Received honorarium from Abbvie, DKSH, Janssen, Novartis and Pfizer.

Abstract
BackgroundThermal imaging (TI) is a portable, low cost imaging tool with high feasibility for use. Clinical joint assessment.Is routinely performed in rheumatoid arthritis (RA) patient care.ObjectivesTo assess a combined TI and clinical joint assessment (CTCA) approach in comparison with TI alone using ultrasound (US) detected joint inflammation outcomes as a gold standard.MethodsBilateral (BL) hand and wrist (22 joint sites) were assessed in this cross-sectional study. For TI (performed in a draft free room with a controlled temperature of around 22°C), the adjusted maximum (Tmax), minimum (Tmin) and average (Tavg) temperatures were derived by subtracting a control temperature (lowest Tmin at the joints per subject) from the Tmax, Tmin and Tavg per joint. US power Doppler (PD) and greyscale (GS) joint inflammation were graded semi-quantitatively (0-3) using validated scoring methods. Joint swelling and tenderness were graded as yes = 1 or no = 0. To increase the relative weightage of CTCA-MAX, CTCA-MIN and CTCA-AVG on the CTCA scores, if the joint was swollen and/or tender, the adjusted Tmax, Tmin and Tavg at each joint were multiplied by a factor of 2; otherwise, they remained unchanged. Receiver operating characteristic (ROC) analysis assessed the performance of TI and CTCA in identifying joints with US PD score > 1 and GS score > 1. A parameter was selected as a univariate predictor if statistically significant (P < 0.05) with area under the ROC curve (AUC) ≥ 0.70.ResultsThis study included 814 joints from 37 RA patients (mean disease duration, 30.9 months; mean DAS28, 4.43). For both TI and CTCA, out of the 22 joints sites, 3 joint sites were evaluated for PD score > 1 and 14 joint sites for GS score > 1; the remaining joint sites had AUC results unavailable due to small number of outcomes. For TI (Table 1), 3 joint sites had ≥ 1 predictive parameter for either PD score > 1 and/or GS score > 1 as follows: left (L) wrist and right (R) MCPJ 1, AUCs (0.813 to 0.897) for PD score > 1; L wrist and R MCPJs 1 and 3, AUCs (0.808 to 0.947) for GS score > 1. For CTCA (Table 1), 6 joint sites had ≥ 1 predictive parameter for either PD score > 1 and/or GS score > 1 as follows: BL wrists, AUCs (0.726 to 0.899) for PD score > 1; BL wrists, MCPJs 2 and 3, AUCs (0.739 to 0.931) for GS score > 1.Table 1.Identifying joints with ultrasound PD score >1 & GS score >1Thermal Imaging aloneCTCAJointUScriterionParameter (AUC ≥ 0.7& P <0.05)AUC(95% CI)Cut-offJointUScriterionParameter (AUC ≥ 0.7& P <0.05)AUC (95% CI)Cut-offLRLRLPD score >1Adjusted Tmax**0.841 (0.691, 0.992)4.7L & RPD score >1CTCA-MAX**0.899 (0.797, 1)**0.776 (0.578, .973)9.47.3WristAdjusted Tmin**0.813 (0.669, 0.958)2.85WristCTCA-MIN**0.861 (0.735, 0.987)*0.7265.74.45(0.526, 0.926)Adjusted Tavg**0.849 (0.714, 0.985)3.9CTCA-AVG**0.889 (0.781, 0.997)*0.7617.35.95(0.563, 0.959)GS score >1Adjusted Tmax**0.827 (0.687, 0.966)4.7GS score >1CTCA-MAX**0.918 (0.833, 1)**0.81387.3(0.632, 0.994)Adjusted Tmin**0.808 (0.67, 0.947)2.85CTCA-MIN**0.873 (0.761, 0.986)**0.7664.44.45(0.581, 0.951)Adjusted Tavg**0.837 (0.707, 0.967)3.9CTCA-AVG**0.913**0.8025.55.95(0.824, 1)(0.62, 0.985)RPD score >1Adjusted Tmax*0.897 (0.726, 1)5.7L & RGS score >1CTCA-MAX-*0.758-9.8(0.494, 1)MCPJ 1MCPJ 2GS score >1Adjusted Tmax*0.936 (0.813, 1)7.2CTCA-MIN*0.902*0.7392.753.9(0.775, 1)(0.443, 1)Adjusted Tmin*0.932 (0.793, 1)3.95CTCA-AVG*0.931**0.7634.75.5(0.835, 1)(0.474, 1)Adjusted Tavg*0.947 (0.868, 1)4.9L & RGS score >1CTCA-MAX*0.914*0.8736.3512.2(0.735, 1)(0.617, 1)RGS score >1Adjusted Tmax*0.922 (0.76, 1)4.6MCPJ 3CTCA-MIN-*0.902-3.15(0.75, 1)MCPJ 3CTCA-AVG-*0.902-4.1(0.728, 1)Corresponding P-value: statistically significance at *P <0.05, **P<0.01.ConclusionA novel CTCA approach helps discriminate the severity of US detected joint inflammation in RA at more joint sites when compared to TI alone; this includes the commonly affected BL wrists, MCPJs 2 and 3.

Abstract
OBJECTIVE To assess the impact of nonsteroidal anti-inflammatory drugs (NSAIDs) on clinical outcomes of patients receiving anti-PD-1 immunotherapy for hepatocellular carcinoma. METHODS We conducted a retrospective study among 215 patients with primary liver cancer receiving immunotherapy between June, 2018 and October, 2020. The patients with balanced baseline characteristics were selected based on propensity matching scores, and among them 33 patients who used NSAIDs were matched at the ratio of 1∶3 with 78 patients who did not use NSAIDs. We compared the overall survival (OS), progression-free survival (PFS), and disease control rate (DCR) between the two groups. RESULTS There was no significant difference in OS between the patients using NSAIDs (29.7%) and those who did not use NSAIDs (70.2%). Univariate and multivariate analyses did not show an a correlation of NSAIDs use with DCR (univariate analysis: OR=0.602, 95% CI: 0.299-1.213, P=0.156; multivariate analysis: OR=0.693, 95% CI: 0.330-1.458, P=0.334), PFS (univariate analysis: HR=1.230, 95% CI: 0.789-1.916, P=0.361; multivariate analysis: HR=1.151, 95% CI: 0.732-1.810, P=9.544), or OS (univariate analysis: HR=0.552, 95% CI: 0.208-1.463, P=0.232; multivariate analysis: HR=1.085, 95% CI: 0.685-1.717, P=0.729). CONCLUSION Our results show no favorable effect of NSAIDs on the efficacy of immunotherapy in patients with advanced primary liver cancer, but this finding still needs to be verified by future prospective studies of large cohorts.

Type of funding sources: None.
Background
Pulmonary arterial hypertension (PAH) is a progressive disease with significant morbidity and mortality. While intravenous (IV) Epoprostenol, a prostacyclin analogue, has been shown to improve exercise tolerance, symptoms, hemodynamics and survival, there are challenges with initiation and maintenance of this IV therapy.
Purpose
We aim to describe our local experience of the use of IV Epoprostenol in the treatment of PAH patients in Singapore, highlighting various issues and challenges.
Methods
From 2016, patients at a tertiary cardiac institution diagnosed with Group 1 PAH and remaining in intermediate to high risk class with progressive symptoms (despite being on maximum tolerable doses of PhosphoDiEsterase-5 inhibitors and Endothelin-1 receptor antagonists) were assessed and counselled for initiation of Epoprostenol therapy. With a fixed set of local protocols, comprehensive assessment and support of a multi-disciplinary team including physicians, specialist nurses and pharmacists, suitable patients were started on this treatment.
Results
A total of 12 patients (11 female, mean age 42.8 +/- 11.0 years) were included. The average New York Heart Association class of the patients initiated on Epoprostenol was II-III. The pulmonary artery pressures and pulmonary vascular resistance on right heart catheterization prior to initiation was 52.5 (IQR 47.0-54.0) mmHg and 12.6 (IQR 10.0-14.2) Woods respectively. The duration from diagnosis to time of initiating Epoprostenol was 89 (IQR 62-140) months. Epoprostenol was generally well tolerated. The most common side effect experienced was diarrhea (5/12 patients) followed by headache and musculoskeletal complains (3/12 patients each). Of the 12 patients, 6 passed away after 12 (IQR 10-16) months of Epoprostenol therapy. Of the remaining 6, PAH was diagnosed 110 (IQR 104-136) months ago and Epoprostenol therapy has been continued for 17 (IQR 14-27) months. Of those who survived, right ventricle size and PA pressures on echocardiography remained relatively stable as compared to those who passed on. 2 patients had line related infections requiring a line change 1 and 2 times respectively.
Conclusion
While not without its challenges, the establishment of concrete protocols with the support of a multidisciplinary team allows for the introduction of IV Epoprostenol as an additional potential line of effective therapy for PAH patients in Singapore.

Background Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening disease with a poor prognosis if left untreated. Pulmonary endarterectomy is the standard treatment for CTEPH, but around 40% of CTEPH patients are non-eligible for surgery.
Purpose To investigate the efficacy and safety of refined balloon pulmonary angioplasty (BPA) for inoperable CTEPH in a prospective multicenter registry from China.
Methods We conducted a prospective multicenter cohort study using the data from National Rare Disease Registry System of China. Total 140 consecutive patients with inoperable CTEPH who completed BPA between Jan 2016 and Dec 2020 were enrolled. The key efficacy outcomes were changes from baseline to re-evaluation in mean pulmonary arterial pressure, pulmonary vascular resistance, and six-minute walking distance. The safety outcomes were procedure-related complications. The survival outcome was all-cause mortality.
Results Among the 140 patients who completed BPA, the mean age at diagnosis was 58 ± 14 years and 60.0% were female. At re-evaluation, the least-squares mean change from baseline was -18.3 mm Hg (95% confidence interval [CI], -19.9 to -16.6, P < 0.001) in mean pulmonary arterial pressure, -5.3 Wood U (95% CI, -5.9 to -4.6, P < 0.001) in pulmonary vascular resistance, and 87 meters (95% CI, 74 to 101, P < 0.001) in six-minute walking distance. BPA procedure-related complications occurred in 109 of 650 BPA sessions (16.8%), but severe complications requiring noninvasive positive pressure ventilation only occurred in 4 (0.6%) BPA sessions. During a mean follow-up time of 32 ± 14 months, 4 patients died, including 2 peri-procedural deaths, contributing to the survival rates of 97.8% (95% CI, 93.4 to 99.3) at 1 year and 96.9% (95% CI, 91.9 to 98.8) at 3 and 5 years.
Conclusion Refined BPA appears to be an effective therapeutic option for inoperable CTEPH patients with acceptable safety profiles. Abstract Figure. Images of BPA Efficacy in a Patient Abstract Figure. Efficacy outcomes of BPA

Abstract
Abstract
Background
The clinical features and long-term outcomes of patients with pulmonary Takayasu's arteritis associated pulmonary hypertension (PTA-PH) have not been well studied.
Purpose
To assess the clinical characteristics and long-term survival outcome in patients with PTA-PH.
Methods
We conducted a multi-center cohort study using the clinical, functional, and hemodynamic data from the National Rare Diseases Registry System of China. Patients with Takayasu's arteritis and pulmonary artery involvement, who fulfilled the 1990 American College of Rheumatology and/or modified Ishikawa criteria, from 13 referral centers of China, were included. The diagnosis of pulmonary hypertension (PH) was confirmed by right heart catheterization findings. The primary outcome was time from diagnosis of PTA-PH to the occurrence of all-cause death.
Results
Between Jan. 2007 and Jan. 2019, a total of 140 patients with PTA-PH were included, with a mean age of 41.4±14.3 years at diagnosis, and a female predominance (81%). The most common symptoms were exertional dyspnea (91%) and hemoptysis (36%). The majority of patients (87%) exhibited bilateral pulmonary artery involvement. Pulmonary lobar artery was the most frequently affected vessel (100%), followed by segmental artery (82%) and left/right pulmonary artery trunk (49%). Severely compromised hemodynamic profiles were identified in these patients, indicating by elevated mean pulmonary artery pressure (48, interquartile range [IQR] 38–59 mm Hg) and pulmonary vascular resistance (9.4, IQR 5.7–13.3 Wood U). The overall 1-year, 3-year, and 5-year survival rates in PTA-PH were 94.0%, 83.2%, and 77.2%, respectively (Figure). Predictors associated with increased risk of all-cause death were the presence of syncope (hazard ratio [HR]: 4.88; 95% CI: 1.62–14.74; p=0.005), N-terminal pro-B type natriuretic peptide level (HR: 1.04; 95% CI: 1.02–1.06; p<0.001), and right atrial pressure (HR: 1.07; 95% CI: 1.02–1.73; p=0.009).
Conclusions
In this national registry study, the reported clinical features and long-term prognosis of patients with PTA-PH are novel findings. These findings may provide new insights on this specific pulmonary hypertension entity.

Abstract
Background:A novel combined thermal and ultrasound (CTUS) imaging approach in rheumatoid arthritis (RA) was recently shown to be superior to either imaging modality alone in terms of correlation with the 28-joint disease activity score (DAS28).Objectives:To determine the performance of CTUS imaging in identifying RA patients with at least moderate disease activity (DAS28 > 3.2).Methods:Bilateral hand (22 joints) thermal and ultrasound (US) imaging was performed. Thermal imaging provides the surface temperature readings at the joints with MAX, AVG and MIN derived per patient by summing the temperature differences with a control temperature, for the respective maximum (Tmax), average (Tavg) and minimum (Tmin) temperatures at each joint. US imaging assesses joint inflammation by summing up the power Doppler (PD) and grey-scale (GS) joint inflammation scores (graded 0-3 at each joint recess) at each joint to obtain the respective total PD and total GS scores per patient. CTUS imaging utilizes data from both thermal and US imaging to derive the MAX (PD), AVG (PD) and MIN (PD) by multiplying MAX, AVG and MIN by a factor of 2 when a patient’s Total PD > median score, which otherwise remained the same as the MAX, AVG and MIN. The results of the imaging parameters were compared between patients with DAS28 ≤ 3.2 and those with DAS28 > 3.2. Sensitivity (Sn), specificity (Sp) and receiver operating characteristic (ROC) curve analysis was performed to determine if the use of CTUS imaging can help identify patients with DAS28 > 3.2.Results:In this cross-sectional study, 814 joints from 37 RA patients (75.7% female; 75.7% Chinese; baseline mean disease duration, 30.9 months; baseline mean DAS28, 4.43) were imaged. The mean (SD) values for the CTUS—but not single modality—imaging parameters (Table 1) were all significantly greater among patients with DAS28 > 3.2 versus those with DAS28 ≤ 3.2 (P-values were all <0.01). Based on cut-off levels of (a) MAX (PD) ≥ 94.5, (b) MIN (PD) ≥ 42.3 and (c) AVG (PD) ≥ 64.6 in identifying patients with DAS28 > 3.2, the respective area under the ROC curves (AUCs) (95%CIs) were (a) 0.731 (0.541, 0.921) with Sn = 58.1%; Sp = 100.0%; negative predictive value (NPV) = 31.6%; positive predictive value (PPV) = 100.0%; accuracy = 64.9%, (b) 0.758 (0.591, 0.925) with Sn = 61.3%; Sp = 100.0%; NPV = 33.3%; PPV = 100.0%; accuracy = 67.6% and (c) 0.763 (0.596, 0.931) with Sn = 61.3%; Sp = 100.0%; NPV = 33.3%; PPV = 100.0%; accuracy = 67.6%.Conclusion:The severity of joint inflammation as detected by CTUS—but not single modality—imaging parameters were significantly greater among patients with DAS28 > 3.2 versus those with DAS28 ≤ 3.2. For the first time ever, by applying ROC analysis, this has helped to determine cut-off MAX (PD), MIN (PD) and AVG (PD) levels for identifying patients with DAS28 > 3.2; the usefulness of these cut-off levels will require further validation in independent RA cohorts.Table 1.Comparison of imaging parameters between patient groups.Imaging ParameterDAS28 Mean (95% CI)Difference (95% CI)P-valueDAS28 ≤ 3.2DAS28 > 3.2MAX (PD)75.25 (58.8, 91.7)119.5 (101.12, 137.87)-44.25 (-70.49, -18.01)0.0022**MIN (PD)33.72 (25.82, 41.61)57.51 (47.63, 67.39)-23.79 (-37.13, -10.45)0.0012**AVG (PD)50.72 (39.45, 61.98)85.39 (71.89, 98.88)-34.67 (-53.27, -16.07)0.0008***MAX67.38 (50.75, 84.02)82.23 (74.71, 89.75)-14.85 (-34.11, 4.42)0.1268MIN30.27 (22.06, 38.47)40.02 (35.02, 45.03)-9.75 (-22.18, 2.66)0.1198AVG45.45 (33.94, 56.96)59.11 (52.99, 65.23)-13.66 (-29.04, 1.72)0.0801Total PD2.83 (-0.23, 5.9)3.65 (2.71, 4.58)-0.82 (-3.39, 1.77)0.5269Total GS6.67 (1.31, 12.02)6.58 (4.12, 9.04)0.09 (-6.21, 6.38)0.9780Statistically significant: **P<0.01, ***P<0.001.Disclosure of Interests:None declared

HIF-1α Mediates Osteoclast-Induced Mandibular Condyle Growth via AMPK Signaling. J Dent Res 2020; 99:1377-1386.

Abstract
During the mandibular condylar growth, the absorption of calcified cartilage matrix induced by osteoclasts is crucial for the continuous endochondral osteogenesis. Meanwhile, recent studies showed that subchondral bone resided within the low-oxygen microenvironment, and our previous study revealed that hypoxia-inducible transcription factor 1α (HIF-1α) promoted osteoclastogenesis under hypoxia. However, whether HIF-1α regulates the function of osteoclasts in the mandibular condyle cartilage remains elusive. Our study indicated that severe deformity of the mandibular condyle was displayed in 10-wk-old osteoclast-specific HIF-1α conditional knockout (CKO) mice, accompanied by shortened length of condylar process and disorganized fibrocartilage. In 1-, 2-, and 4-wk-old CKO mice, the size of the hypertrophic layer and chondrocytic layer was significantly thickened. In the chondrocytic layer, chondrocytes were atrophied, showing a form of apoptosis in 4-wk-old CKO mice. Furthermore, an increase in the thickness of the fibrous and proliferating layer was observed in 10-wk-old CKO mice, as well as a significant decrease in that of the chondrocytic and hypertrophic chondrocyte layers. Interestingly, the articular surface of the condylar process abnormally presented a horizontal concave shape, and a disk-like acellular connective tissue appeared. In addition, genetic ablation of HIF-1α blunted cartilage matrix loss by subchondral osteoclast deficiency, resulting in a high subchondral bone mass phenotype, accompanied with a decreased number of blood vessels, alkaline phosphatase staining, and vascular endothelial growth factor (VEGF) expression. Mechanistically, the number of osteoclasts in the center of the condyle in CKO mice was significantly reduced by attenuated expression of adenosine 5′-monophosphate-activated protein kinase (AMPK) signaling. These findings reveal a novel influence of HIF-1α function in osteoclasts on maintenance of osteoclast-induced resorption of calcified cartilage matrix via AMPK signaling, as well as subchondral bone formation through VEGF-dependent angiogenesis in bone marrow.

Abstract
Objective: To investigate the correlation of peripheral venous oxygen saturation (SpvO(2)) with mixed venous oxygen saturation (SvO(2)), pulmonary vascular resistance (PVR) and cardiac index (CI) in patients with pulmonary hypertension (PH), in order to predict these parameters using SpvO(2) and assess the prognosis of patients. Methods: Hospitalized patients diagnosed with PH by right heart catheterization in the Guangzhou Institute of Respiratory Diseases from July 2015 to October 2016 were retrospectively analyzed. Parameters during the right heart catheterization, including SvO(2,)SpvO(2,)cardiac output (CO) and mean pulmonary arterial pressure (mPAP) were recorded, while CI, PVR and other parameters were indirectly calculated. The correlation between SpvO(2) and SvO(2,)CO, CI, mPAP, PVR and other parameters were respectively analyzed and compared between groups. Results: A total of 77 PH patients were selected, which comprised of 39 males and 38 females. The results revealed that SpvO(2) was correlated positively with SvO(2,)CI and PaO(2) (P<0.05), but negatively with PVR, total pulmonary resistance (TPR), systemic vascular resistance, right atrial diameter and right ventricular diameter (P<0.05). In the group with SpvO(2) <65%, the dilation of the right atrium and right ventricle was more significant, the WHO heart function grade was worse, CI, systemic systolic pressure and mean systemic pressure were lower, and PVR and TPR were higher, as compared to those in the group with SpvO(2) ≥65%. (P<0.05). Conclusions: There was good consistency between SpvO(2) and SvO(2). Furthermore, SpvO(2) could indirectly reflect the CI, PVR and changes in right heart structure of PH patients, providing reference for the clinical prediction of CI and PVR, as well as the prognosis of PH patients, through the use of SpvO(2). Low SpvO(2) indicated a severe condition and poor prognosis.

Gene expression profiling reveals differential patterns between microcystic congenital cystic adenomatoid malformation and congenital lobar emphysema. Early Hum Dev 2019; 128:77-80. [PMID: 30583279 DOI: 10.1016/j.earlhumdev.2018.12.014] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2018] [Revised: 12/18/2018] [Accepted: 12/18/2018] [Indexed: 11/29/2022]
Abstract
INTRODUCTION Congenital cystic adenomatoid malformation (CCAM), especially type-III, shares similar sonographic features with congenital lobar emphysema (CLE) in routine ultrasound scan. Thus, prenatal differentiation of CLE from a microcystic CCAM is challenging and difficult in practice. Discovery of molecular biomarkers has important clinical significance. METHODS We profiled gene expression in lung tissue from four CCAM type-III and five CLE subjects by microarray. A bioinformatic tool was used for signal pathways enrichment analysis. Further, quantitative reverse transcriptase PCR (qRT-PCR) was used to verify the results. RESULTS A total of 426 genes were identified to be significantly differentially expressed (fold-change >2.0, q value <0.05) between microcystic CCAM and CLE. Of these differentially expressed genes (DEGs), 392 were upregulated and 34 were downregulated in microcystic CCAM compared with CLE. Unsupervised clustering of the "expressed" genes could clearly delineate the CCAM and CLE samples. We also confirmed that eight randomly chose genes were differentially expressed at the mRNA level between CCAM and CLE. CONCLUSIONS CCAM type-III and CLE have differential gene expression patterns. Our pilot study may gain a deeper understanding of the organogenetic origins and pathogenesis of these conditions. The suggestive candidates may serve as potential biomarkers for definitive diagnosis of congenital cystic lung lesions and eventually to treat them appropriately.

Abstract
Objective: To investigate the effect of intrauterine intervention on severe primary fetal hydrothorax. Methods: Twelve cases with severe fetal primary hydrothorax who underwent prenatal intervention from January 2014 to December 2017 in Guangdong Women and Children Hospital were retrospectively reviewed. Results: The median gestational age of prenatal diagnosis was 30.8 weeks (24.0-33.0 weeks) . All cases were excluded congenital chromosomal abnormalities by prenatal diagnosis, and had no complications of pregnancy during prenatal diagnosis and had hydrothorax. Three cases (3/12) were right hydrothorax, the other 9 cases (9/12) were bilateral. Thoracoamniotic shunting was performed in 7 cases (7/12) . Thoracentesis was performed in 5 cases (5/12) , and the hydrothorax reappeared soon after operation in 4 cases, shunt placement was performed again. The hydrothorax was dissolved in 2 cases, released in 6 cases.Tube falling off occurred in 1 case,treatment was abandoned in 1 case and intrauterine fetal death happened in 1 case, and 1 case wasn't rechecked by ultrasonic due to premature birth following thoracentesis. In 10 cases who had deliveries, 5 newborns (5/10) were premature, 6 newborns (6/10) underwent assisted mechanical ventilation, 8 newborns (8/10) underwent thoracic close drainage, all of them were discharged when hydrothorax resolved. Conclusions: Antenatal intervention may improve the chance of survival in severe primary fetal hydrothorax. Thoracoamniotic shunting is the first-choice for the primary severe fetal hydrothorax.

Abstract
The bacterial type III secretion system, or injectisome, is a syringe shaped nanomachine essential for the virulence of many disease causing Gram-negative bacteria. At the core of the injectisome structure is the needle complex, a continuous channel formed by the highly oligomerized inner and outer membrane hollow rings and a polymerized helical needle filament which spans through and projects into the infected host cell. Here we present the near-atomic resolution structure of a needle complex from the prototypical Salmonella Typhimurium SPI-1 type III secretion system, with local masking protocols allowing for model building and refinement of the major membrane spanning components of the needle complex base in addition to an isolated needle filament. This work provides significant insight into injectisome structure and assembly and importantly captures the molecular basis for substrate induced gating in the giant outer membrane secretin portal family.

Abstract
Objective: To analyze the characteristics of ECG in patients with pulmonary hypertension(PH) and explore their correlation with pulmonary vascular resistance(PVR), mean pulmonary arterial hypertension(mPAP) and cardiac index(CI). Methods: A total of 186 patients with right heart catheterization were enrolled in the Department of Respiratory of the First Affiliated Hospital of Guangzhou Medical University from August 2015 to October 2017. Patients with normal pulmonary artery pressure, incomplete clinical data and repeated examinations were excluded and there were 101 patients with pulmonary hypertension included. The results of ECG parameters and right heart catheterization were collected to analyze the ECG characteristics of patients with different genders and their correlation with PVR, mPAP and CI. Results: Among all PH patients, the duration of QRS axial in male group was significantly longer than that of the female group [(110.38±15.829) vs. (98.63±18.041) ms, P<0.001], and the S wave amplitude in V5 was significantly higher compared to female group [(1.304±1.356) vs. (0.648±0.663) mv, P<0.001]. Their heart rate-corrected QT interval (QTc), QRS axis, S wave amplitude in Ⅰ, S and R wave amplitude in V1, R/S ratio in V1, S wave amplitude V5, all had a correlation with their PVR and the S wave amplitude in V1 was negatively correlated with PVR (r=-0.441, P<0.001). In the male group, PVR was not correlated with R/S ratio in V1 and S wave amplitude in V5. While PVR in the female group was significantly correlated with QTc, R wave amplitude in V1, R / S ratio in V1. In all PH patients, their P wave duration in Ⅱ, QRS axis and S wave amplitude in Ⅰ, S wave and R wave amplitude in V1, S wave amplitude in V5, QTc, R/S ratio in V1, all had correlations with mPAP (P<0.05). In male group, mPAP was not correlated with QTc, P wave duration in Ⅱ, and the S wave amplitude in V5 (P>0.05). The mPAP in the female group was only related to the S wave and R wave amplitude in V1, and S amplitude in Ⅰ and S wave amplitude in V5 (P<0.05). The CI was positively correlated with the S wave amplitude in V1 (r=0.34, P<0.001), and negatively correlated with the QRS axis (r=-0.219, P=0.04); CI in male group was not correlated with QRS axis(P=0.073), but correlated with QTc (r=-0.296, P=0.044). Conclusion: There were gender differences in QRS duration and S wave amplitude in V5 in patients with pulmonary hypertension. The QRS axis and the S wave amplitude in V1 were related to the heart index. There was a difference in the correlation between ECG and PVR, mPAP and CI in patients of different genders with pulmonary hypertension.

Abstract
OBJECTIVES To evaluate the accuracy of three-dimensional stereophotogrammetry by comparing values obtained from direct anthropometry and the 3dMDface system. To achieve a more comprehensive evaluation of the reliability of 3dMD, both linear and surface measurements were examined. SETTING AND SAMPLE POPULATION UCLA Section of Orthodontics. Mannequin head as model for anthropometric measurements. MATERIAL AND METHODS Image acquisition and analysis were carried out on a mannequin head using 16 anthropometric landmarks and 21 measured parameters for linear and surface distances. 3D images using 3dMDface system were made at 0, 1 and 24 hours; 1, 2, 3 and 4 weeks. Error magnitude statistics used include mean absolute difference, standard deviation of error, relative error magnitude and root mean square error. Intra-observer agreement for all measurements was attained. RESULTS Overall mean errors were lower than 1.00 mm for both linear and surface parameter measurements, except in 5 of the 21 measurements. The three longest parameter distances showed increased variation compared to shorter distances. No systematic errors were observed for all performed paired t tests (P<.05). Agreement values between two observers ranged from 0.91 to 0.99. CONCLUSIONS Measurements on a mannequin confirmed the accuracy of all landmarks and parameters analysed in this study using the 3dMDface system. Results indicated that 3dMDface system is an accurate tool for linear and surface measurements, with potentially broad-reaching applications in orthodontics, surgical treatment planning and treatment evaluation.

Abstract
For coupled structures surrounded by heavy fluids, it is difficult to obtain dispersion curves from an eigenvalue analysis, because the external fluid term in the coupled equation includes transcendental functions for frequency and wavenumber. Thus, in this study, the acoustic mass of the external fluid was approximated as a function of frequency or wavenumber only. The coupled equation can then be used to calculate eigenvalues, and can estimate dispersion curves from an eigenvalue analysis. Because of this assumption, those dispersion curves will contain errors. Accordingly, those errors were evaluated in this study through a comparison with a dispersion curve derived from forced responses. The acoustic mass was also evaluated for a water-loaded plate; this can be formulated theoretically. As a result, the acoustic mass is less sensitive to frequency changes than wavenumber changes, and using the fluid term defined at a low frequency has advantages when estimating the dispersion curve. Finally, the generality of the proposed method was identified through the application for a submerged cylindrical shell.

Abstract
Multiple myeloma (MM), a type of malignant tumor, is characterized by dysplasia of clonal plasma cells in the bone marrow. People with MM will have damaged organs or tissues due to secretion of large amounts of monoclonal immunoglobulin or fragments (M protein). Despite improved survivability by novel treatment strategies over the last decade, MM is still incurable by current therapies. Long noncoding RNAs (lncRNAs), with length of more than 200 nucleotides, have been reported to act as important regulators in many diseases, including MM. Recent studies have reported aberrant lncRNA expression in MM; these dysregulated lncRNAs can play oncogenic and/or tumor-suppressive roles in the development and progression of MM. In this article, we present a general overview on the role of lncRNAs in MM pathogenesis and discuss their potential as prognostic biomarkers and targets for treatment.

Abstract
RATIONALE Congenital diaphragmatic hernia (CDH) associated congenital anomalies are present in about 25%. Congenital short esophagus (CSE) is a relatively rare condition. Both CDH and congenital intrathoracic stomach caused by CSE can be diagnosed in utero. However, CSE can be easily misdiagnosed in utero. PATIENT CONCERNS We present a case of left CDH with CSE in a female neonate who was diagnosed at 24 weeks gestational age by antenatal ultrasound. DIAGNOSES The neonate with CDH and congenital intrathoracic stomach due to CSE was confirmed by operation. Gastroesophageal reflux disease (GRED) occurred after operation. INTERVENTIONS The left diaphragm was repaired, and gastric fixation by gastropexy, gastric folding anti-reflux procedure and operation of longitudinal incision and transverse suture for pyloroplasty procedure was underwent. Gastroesophageal reflux disease (GRED) occurred after operation and jejunal tube feeding was placed. OUTCOMES This patient is currently alive 12 months post-operation with GRED. LESSONS To our knowledge, this is the first documented case of this rare type of CDH combined with congenital intrathoracic stomach caused by CSE. This condition could not be surgically repaired due to the extremely short esophagus. Early recognition of intrathoracic stomach associated with CSE is important as it is associated with difficult management and significant postnatal complications. The prognosis is cautiously guarded, and the parents should be appropriately counseled.

Abstract
RATIONALE The occurrence of congenital cystic adenomatoid malformation (CCAM) and vascular ring (VR) is extremely rare. PATIENT CONCERNS We present a case of left CCAM with VR consisting of a left aortic arch and right descending aorta with left tracheal compression causing atelectasis. DIAGNOSES A high-risk male neonate with the diagnosis of left CCAM was diagnosed at 20 weeks gestational age by antenatal ultrasound. Chest CT revealed multiple cysts in the left inferior lung. Cardiac CT showed VR consisting of a left aortic arch and right descending aorta with left tracheal compression causing atelectasis. INTERVENTIONS left inferior lobectomy was performed. Cardiac CT showed VR consisting of a left aortic arch and right descending aorta with left tracheal compression causing atelectasis. Descending aorta transposition was performed. OUTCOMES The patient recovered smoothly and remained asymptomatic during the 12-months of postoperative follow-up period. LESSONS We report this rare case of CCAM with VR consisting of left aortic arch and right descending aorta with left tracheal compression causing atelectasis. From the findings of this report, early surgical treatment is recommended. Although the prognosis after surgery remained good, second surgery can be avoided if VR was detected early.

Abstract
Objective To analyze the Oncomelania hupensis snail distribution and the changes of snail situation in Changzhou City from 2013 to 2016, so as to provide the evidence for formulating the schistosomiasis prevention and control interventions. Methods The data of snail monitoring in Changzhou City from 2013 to 2016 were collected and statistically analyzed. Results The total area with snails was 40.17 hm2 and the newly discovered area was 30.63 hm2 in Changzhou City from 2013 to 2016. In the four years, 3 454 snails were dissected, and no schistosome infected snails were found. There were totally 51 spots with snails, and the areas with snails of different types of marshland, inland and mountain were 12.13 (30.19%), 25.54 hm2 (63.57%) and 2.51 hm2 (6.24%), respectively. In the newly discovered snail environment, the areas of types of marshland and inland were 8.00 hm2 (26.12%) and 22.63 hm2 (73.88%), respectively. The main causes for snail existence were external input and adjacent diffusion. In the past four years, the total snail control area with molluscicides was 71.74 hm2, the consolidated snail control area with molluscicides was 155.15 hm2, and the total environmental modification areas in the current snail spots and historic snail spots were 15.90 hm2 and 11.30 hm2 respectively. Conclusion The diffusion of snails in inland rivers is the key of the newly discovered snail areas in Changzhou City in recent years, and the snail monitoring and control measures should be strengthened in the future.

Abstract
BACKGROUND AND AIMS Adiponectin, an adipose-secreted protein that has been linked to insulin sensitivity, plasma lipids, and inflammatory patterns, is an established biomarker for metabolic health. Despite clinical relevance and high heritability, the determinants of plasma adiponectin levels remain poorly understood. METHODS AND RESULTS We conducted the first epigenome-wide cross-sectional study of adiponectin levels using methylation data on 368,051 cytosine-phosphate-guanine (CpG) sites in CD4+ T-cells from the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN, n = 991). We fit linear mixed models, adjusting for age, sex, study site, T-cell purity, and family. We have identified a positive association (regression coefficient ± SE = 0.01 ± 0.001, P = 3.4 × 10-13) between plasma adiponectin levels and methylation of a CpG site in CPT1A, a key player in fatty acid metabolism. The association was replicated (n = 474, P = 0.0009) in whole blood samples from the Amish participants of the Heredity and Phenotype Intervention (HAPI) Heart Study as well as White (n = 592, P = 0.0005) but not Black (n = 243, P = 0.18) participants of the Bogalusa Heart Study (BHS). The association remained significant upon adjusting for BMI and smoking in GOLDN and HAPI but not BHS. We also identified associations between methylation loci in RNF145 and UFM1 and plasma adiponectin in GOLDN and White BHS participants, although the association was not robust to adjustment for BMI or smoking. CONCLUSION We have identified and replicated associations between several biologically plausible loci and plasma adiponectin. These findings support the importance of epigenetic processes in metabolic traits, laying the groundwork for future translational applications.

Abstract
Direct pulp capping involves the placement of dental materials directly onto vital pulp tissues after deep caries removal to stimulate the regeneration of reparative dentin. This physical barrier will serve as a "biological seal" between these materials and the pulp tissue. Although numerous direct pulp capping materials are available, the use of small bioactive compounds that can potently stimulate and expedite reparative dentin formation is still underexplored. Here, the authors compared and evaluated the pro-osteogenic and pro-odontogenic effects of 4 small bioactive compounds- phenamil (Phen), purmorphamine (Pur), genistein (Gen), and metformin (Met). The authors found that these compounds at noncytotoxic concentrations induced differentiation and mineralization of preosteoblastic MC3T3-E1 cells and preodontoblastic dental pulp stem cells (DPSCs) in a dose-dependent manner. Among them, Phen consistently and potently induced differentiation and mineralization in vitro. A single treatment with Phen was sufficient to enhance the mineralization potential of DPSCs in vitro. More importantly, Phen-treated DPSCs showed enhanced odontogenic differentiation and mineralization in vivo. Our study suggests that these small bioactive compounds merit further study for their potential clinical use as pulp capping materials.
