Abstract
This study was aimed to assess the protective effects of γ-irradiated Astragalus polysaccharides (IAPS) on the development of small intestine and intestinal mucosal immunity of immunosuppressed broilers induced by cyclophosphamide (CPM). A total of 384 one-day-old broiler chicks with similar initial weight were randomly assigned into 6 groups: non-treated group (control), and CPM-treated groups fed either a basal diet or the diets containing 900 mg/kg APS, or 900, 600, 300 mg/kg IAPS, respectively. On days 16, 18, and 20, all broilers except for control group were intramuscularly injected with 0.5 mL CPM (40 mg/kg of BW). Broilers in the control group were intramuscularly injected with 0.5 mL sterilized saline (0.75%, wt/vol). This trial was lasted for 21 d. The results revealed that both APS and IAPS treatment elevated the duodenal IgA-producing cells number and the jejunal mRNA expression of interleukin-2 (IL-2), interleukin-10 (IL-10), and interferon γ of CPM-injected broilers (P < 0.05). The decreased jejunal villus height (VH), the ratio of VH to crypt depth (V/C), as well as the intestinal intraepithelial lymphocytes (IELs) and goblet cells number in CPM-injected broilers were elevated by dietary supplementation with 900 mg/kg APS or 900, 600 mg/kg IAPS (P < 0.05). The CPM-induced decrease in jejunum index, the duodenal VH and the jejunal IgA-producing cells number were only improved in the 900 mg/kg IAPS group (P < 0.05). Furthermore, the number of IELs and IgA-producing cells in duodenum, VH, V/C, the number of goblet cells, and mRNA expression of IL-2 and IL-10 in jejunum were higher in the 900 mg/kg IAPS group than those in the 900 mg/kg APS group (P < 0.05). In summary, IAPS possessed stronger immunomodulatory effect than APS at the same supplementation level. Therefore, gamma irradiation can be used as an alternative treatment to enhance the immunomodulatory activity of APS.

Abstract
Objective: To compare the histologic features of immune-mediated hepatitis (IMH) due to immune checkpoint inhibitors (ICIs) monotherapy and combined ICIs anti-angiogenesis tyrosine kinases (TKIs) targeted therapy. Methods: Twenty-one IMH patients who had liver biopsy during ICIs treatment in Zhongshan Hospital of Fudan University from 2015 to 2019 were included. Among them, ten were treated with ICIs monotherapy, and 11 were treated with combined ICIs and anti-angiogenesis targeted therapy. The histologic features of IMH were assessed by HE staining and PD-L1/2 was evaluated by immunohistochemical staining. Results: Patients treated with monotherapy ICIs presented with different levels of lobular hepatitis and portal inflammation. Besides, there were also cholangitis, endothelialitis, Kupffer cells activation and peliosisi hepatitis. Eight cases (8/10) showed mild and two cases (2/10) showed moderate hepatic injury. As for patients receiving combined ICIs and TKIs therapy, the extent of IMH was more severe, with four cases (4/11) showing moderate-severe liver injury, with confluent or bridging necrosis, portal inflammation, cholangitis, interface hepatitis. Among these, one patient developed acute severe hepatitis with massive hepatocyte necrosis and died of multisystem dysfunction. In those cases with severe liver injury, many CD8 positive lymphocytes aggregated in the portal area and hepatic sinusoid, and PD-L1 was expressed in many endothelial cells. There were both 2 cases of death in ICIs monotherapy and combination therapy group. Among the latter group, 1 patient developed acute severe hepatitis with massive hepatocyte necrosis and died of multisystem dysfunction. Conclusion: Compared with ICIs monotherapy, combined ICIs and anti-angiogenesis targeted TKIs therapy may cause overlapping hepatic injury, leading to severe IMH.

Abstract
Objective: To characterize the ocular saccadic abnormality in neuromyelitis optica spectrum disorder (NMOSD) patients, and explore the relationship between ocular saccadic abnormality and the overall disability and visual function state. Methods: For the 110 consecutive NMOSD patients who visited the Department of Neurology of Beijing Tongren Hospital from July 2015 to July 2017, a 120 Hz spatial resolution infrared video nystagmus system was used to perform a quantitative horizontal saccade examination. All patients were assessed for overall disability status using the extended disability status scale (EDSS). The subjective visual function status was evaluated using the National Eye Institute-Visual Function Questionnaire (NEI-VFQ 25) and the 10-item neuro-ophthalmic supplement questionnaire (Suppl. 10). Results: A total of 68 (61.8%) of 110 NMOSD patients had horizontal saccadic abnormalities, including 50 cases (45.5%) with abnormal saccade latency, 34 cases (30.9%) with abnormal saccade accuracy and 22 cases (20.0%) with abnormal speed. Patients with abnormal saccade had more intracranial lesions and higher EDSS scores than those with normal eye movements (P=0.006 and P<0.001, respectively). Patients with abnormal saccade had lower Supp.10 scores than the normal patient (P=0.004), while there was no significant difference of NEI-VFQ 25 scores between the two groups (P=0.079). Conclusions: The horizontal saccadic abnormality is common in the NMOSD patients, and the overall disability status and visual function-related quality of life are worse. Quantitative horizontal saccade examination can provide important information on intracranial lesions and neuronal function impairment, and thus it should be emphasized in clinical settings.

Abstract
Objective: To characterize the clinical features of patients with Behcet's uveitis. Methods: Retrospective case series study. Medical records of patients who were diagnosed as Behcet's uveitis in Peking Union Medical College Hospital between January 1998 and November 2015 were retrospectively reviewed. Information about the clinical manifestation, complication, best corrected visual acuity (logarithm of the minimum angle of resolution) and medication was collected. The correlation of visual acuity and the disease course, as well as inflammation relapse times before and after biological agents applied was analyzed. Chi square test and Wilcoxon signed-rank test were applied for statistical analysis. Results: A total of 132 patients (233 eyes) with Behcet's uveitis were included, among which 104 (78.8%) were male and 28 (21.2%) were female, with statistically significant difference (χ(2)=43.76, P<0.01). The average age at the onset of uveitis was (28.9±8.7) years, with most patients at 21-40 years (102 cases, 77.3%). Oral aphthae (132 cases, 100.0%) were the most frequent extraocular manifestations, followed by dermatologic lesions (103 cases, 78.0%), genital ulcers (90 cases, 68.2%), arthritis (44 cases, 33.3%) and positive pathergy test (39 cases, 29.5%). Ocular involvement was bilateral in 76.5% (101 cases) of the patients, and panuveitis was the most common type (110 cases, 83.3%). Complications were seen in 80.7% (188/233) of the eyes, with cataract (58.8%, 137/233) and macular edema (59.1%, 114/193) being the most common anterior and posterior segment complications, respectively. At the eighth year of uveitis, best corrected visual acuity decreased to less than 0.3 in 20.9% (9/43) of the eyes, and more than 1.0 in 39.5% (17/43) of the eyes. A combination of glucocorticoids and immune modulators remained the first line therapy (97.0%, 128/132) for Behcet's uveitis. For 16 refractory cases, an addition of biological agents significantly reduced the inflammation relapse [0.5 (0.0, 1.5) times per year vs. 4.0 (1.0, 5.5) times per year, Z=-2.81, P=0.005]. Conclusions: Behcet's uveitis mainly affects working-age males and manifests as bilateral panuveitis. Complications are commonly seen in uveitic eyes. Patients' visual acuity is significantly impaired. A combination of glucocorticoids and immune modulators is effective for most patients, but for refractory cases, an addition of biological agents provides better effects.

Abstract
Hepatocarcinogenesis is a multi-step process in which detection of precancerous lesions and advanced hepatocellular carcinoma in its progressive stage is crucially important for predicting tumor behavior, estimating the extent of lesions, implementing the optimal treatment strategy, and improving the survival of patients. The rapid development and wide application of liver imaging technology, especially the application of hepatocyte-specific gadoxetate disodium MRI contrast agent (Gd-EOB-DTPA MRI), not only provide information on vascular changes of liver nodules and hepatocyte function, but also has become a precise diagnostic method for differentiating cirrhotic regenerative nodule (RN), low-grade dysplastic nodule (LGDN), high-grade dysplastic nodule (HGDN), early hepatocellular carcinoma and HCC. Hence, the risk for malignant progression is stratified. This review summarizes the value of Gd-EOB-DTPA MRI for early HCC diagnosis and analyzes the key concepts in the multi-step process of HCC development as well as the imaging manifestations of precancerous lesions that may eventually be transformed into typical HCC.

Abstract
On Behalf
SingCLOUD collaborators
Background
Notable regional differences have been observed worldwide in clinical characteristics and outcomes in patients experiencing acute myocardial infarction (AMI). Asian patients present younger and report higher adverse outcomes rates compared to Western cohorts. The reasons are multifactorial, but adherence to medication prescription guidelines is one of the modifiable factors.
Purpose
Our aim was to study the effect of physician adherence to Optimal Medical Therapy (OMT) prescription guidelines on a MACE outcome in a high-risk group of Asian AMI patients over 1 year following percutaneous coronary intervention (PCI).
Method
Data for this retrospective study was from the Singapore Cardiac Longitudinal Outcomes Database (SingCLOUD) pilot study involving AMI patients surviving primary PCI at two tertiary centers from 2012 to 2013. Guideline-directed OMT adherence was defined as concurrent prescription of at least one statin plus dual antiplatelet therapy (DAPT – aspirin plus P2Y12-I). Prescription of β-blockers and ACE-i/ARBs was also recorded. Prescription status and MACE (repeat MI, stroke, death) was recorded at discharge, 3, 6 and 9 months, and 1 year following the index discharge. The cumulative effect of OMT adherence at 3, 6, 9 months and 1 year post-discharge was studied by comparing risk of first MACE among patient groups with complete, partial and non-adherence to OMT prescription guidelines.
Results
2,478 patients, 80.3% males, mean age 60.3 ± 11.7 years were studied. 1094 (44.1%) underwent primary PCI for STEMI. Single drug prescription at discharge for aspirin, P2Y12-I, and statins was 95, 97 and 95.8%, while prescription of β -blockers and ACE-inhibitors was 86.5 and 75.7%. Prescription of statins and aspirin declined gradually while P2Y12-I fell to 67.9% at 6mo and 47.6% at 1 year. Adherence to OMT declined from 92.3% at discharge to 82.1, 58.5, 56.1 and 40.3% at 3, 6, 9 months and 1 year, respectively. Of 342 (13.8%) occurrences of first MACE, 48.5% occurred within 3mo post-discharge. Complete adherence to OMT upon discharge significantly decreased risk of MACE at 3mo (OR = 0.066; 95% CI: 0.054-0.080; p < 0.001) and 12mo (OR = 0.017; 95% CI: 0.010-0.028; p < 0.001) relative to non-adherence.
Conclusion
Over the course of a year in this high-risk group of PCI-treated AMI patients, there was a reduction in prescription adherence to the minimally essential OMT. Complete OMT adherence is beneficial in reducing MACE. Interventions targeting reasons for non-adherence are important in improving patient outcomes.

Abstract
Wooden breast (WB) has emerged as a dramatically increasing myopathy in the poultry industry over the past few years. The objective of this study was to investigate the incidence of WB in a Chinese commercial broiler processing plant, and the consequences on quality attributes, textural properties, and sensory traits. A total of 1,135 breast fillets were collected at the deboning line and assigned to normal, mild, moderate, and severe WB categories by tactile evaluation. The proportion affected by WB was approximately 61.9%. WB fillets appeared heavier and thicker than normal fillets. The degree of WB myopathy was highly correlated with fillet weight and thickness. The meat quality characteristics of cooking loss and purge loss increased along with increasing severity of WB myopathy. Compression tests of raw meat revealed higher cutting strength and shear values for WB. In cooked meat, only severe WB fillets exhibited elevated hardness and chewiness. Finally, moderate and severe WB fillets affected the sensory evaluation by consumers owing to their impaired general appearance, texture, and drip loss. The results suggested that a high proportion of WB broiler fillets would cause detrimental losses to the poultry meat retailing and processing industry.

Abstract
We report constraints on light dark matter (DM) models using ionization signals in the XENON1T experiment. We mitigate backgrounds with strong event selections, rather than requiring a scintillation signal, leaving an effective exposure of (22±3) tonne day. Above ∼0.4 keV_{ee}, we observe <1 event/(tonne day keV_{ee}), which is more than 1000 times lower than in similar searches with other detectors. Despite observing a higher rate at lower energies, no DM or CEvNS detection may be claimed because we cannot model all of our backgrounds. We thus exclude new regions in the parameter spaces for DM-nucleus scattering for DM masses m_{χ} within 3-6 GeV/c^{2}, DM-electron scattering for m_{χ}>30 MeV/c^{2}, and absorption of dark photons and axionlike particles for m_{χ} within 0.186-1 keV/c^{2}.

Abstract
Direct dark matter detection experiments based on a liquid xenon target are leading the search for dark matter particles with masses above ∼5 GeV/c^{2}, but have limited sensitivity to lighter masses because of the small momentum transfer in dark matter-nucleus elastic scattering. However, there is an irreducible contribution from inelastic processes accompanying the elastic scattering, which leads to the excitation and ionization of the recoiling atom (the Migdal effect) or the emission of a bremsstrahlung photon. In this Letter, we report on a probe of low-mass dark matter with masses down to about 85 MeV/c^{2} by looking for electronic recoils induced by the Migdal effect and bremsstrahlung using data from the XENON1T experiment. Besides the approach of detecting both scintillation and ionization signals, we exploit an approach that uses ionization signals only, which allows for a lower detection threshold. This analysis significantly enhances the sensitivity of XENON1T to light dark matter previously beyond its reach.

Abstract
Chronic heat stress can enhance fat synthesis in broilers, and excessive triglyceride (TG) synthesized by the liver needs to be transported to extrahepatic tissues by very low density lipoprotein (VLDL) otherwise will accumulate in the liver, which may even result in hepatic steatosis. To investigate the molecular mechanisms by which chronic heat stress enhances fat synthesis and results in lipid accumulation in the liver of chickens, 144 broilers (Arbor Acres, 28-day-old) were randomly allocated to the normal control (NC, 22°C), heat stress (HS, consistent 32°C), or pair-fed (PF, 22°C) groups for a 14-D trial. The 7 D of heat exposure significantly increased the respiratory rate, relative weight of abdominal fat, the levels of glucose, TG, corticosterone, insulin, and VLDL in plasma, as well as the levels of TG, total cholesterol, acyl-CoA carboxylase (ACC), and fatty acid synthase (FAS) in the liver, and mRNA expression levels of carbohydrate response element-binding protein (ChREBP), ACC, FAS, and microsomal triglyceride transfer protein (MTTP) in comparison with the other 2 groups. After 14 D of heat exposure, the relative weights of abdominal fat and liver and levels of TG and FAS in the liver were significantly higher in the HS group than in the other 2 groups, and there were no significant differences in the respiratory rate, plasma corticosterone concentration, apolipoprotein B (ApoB) level in the liver, and mRNA expression levels of key genes of fat synthesis among the 3 groups. In conclusion, chronic heat exposure activated LXRα pathway and enhanced fat synthesis in the liver after 7 D of heat exposure. After 14 D of heat exposure, heat-stressed broilers exhibited an adaptation to the high temperature in parameters of stress and fat synthesis gene expression levels. Moreover, chronic heat stress resulted in lipid accumulation in the liver of broilers, which is probably because the limited ApoB was not enough to transport the excessive TG synthesized by the liver in chronic heat-stressed broilers.

Abstract
OBJECTIVE To investigate the role of angiotensin-converting enzyme 2 (ACE2) in hyperoxic lung injury. METHODS Adult mice were exposed to 95% O2 for 72 h to induce hyperoxic lung injury, and simultaneously treated with ACE2 agonist diminazene aceturate (DIZE) or inhibitor MLN-4760. ACE2 expression/activity in lung tissue and angiotensin (Ang)-(1-7)/Ang II in bronchoalveolar lavage fluid (BALF), and the severity of hyperoxic lung injury were evaluated. The levels of inflammatory factors in BALF and lung tissue and the expression levels of phospho-p65, p65 and IkBα were measured. Oxidative parameter and antioxidant enzyme levels in lung tissue were measured to assess oxidative stress. Finally, the expression levels of nuclear factor-erythroid-2-related factor (Nrf2), NAD(P)H quinine oxidoreductase 1 (NQO1) and heme oxygenase-1 (HO-1) were measured using Western blotting. RESULTS Hyperoxia treatment significantly decreased lung ACE2 expression/activity and increased the Ang II/Ang-(1-7) ratio, while co-treatment with hyperoxia and DIZE significantly increased lung ACE2 expression/activity and decreased the Ang II/Ang-(1-7) ratio. By contrast, co-treatment with hyperoxia and MLN-4760 significantly decreased lung ACE2 expression/activity and increased the Ang II/Ang-(1-7) ratio. Hyperoxia treatment induced significant lung injury, inflammatory response and oxidative stress, which were attenuated by DIZE but aggravated by MLN-4760. The NF-κB pathways were activated by hyperoxia and MLN-4760 but inhibited by DIZE. The Nrf2 pathway and its downstream proteins NQO1 and HO-1 were activated by DIZE but inhibited by MLN-4760. CONCLUSION Activation of ACE2 can reduce the severity of hyperoxic lung injury by inhibiting inflammatory response and oxidative stress. ACE2 can inhibit the NF-κB pathway and activate the Nrf2/HO-1/NQO1 pathway, which may be involved in the underlying mechanism.

Abstract
1. This study was conducted to assess the effects of graded levels of dietary corn resistant starch (RS) on growth performance, carcass traits, nutrient retention, digestive organ index, intestinal morphology, digestive enzyme activities, and mRNA expression of certain nutrient transporters in broiler chickens.2. A total of 320, 1-d-old Arbor Acres broiler chickens were randomly assigned to five dietary treatments, with eight replicates of eight birds in each. These treatments included one corn-soybean control diet, a corn-soybean based diet containing 20% corn starch, and three diets supplemented with 4%, 8% and 12% RS by replacing corn starch with 6.67%, 13.33% and 20% of Hi-Maize 260® (identified as control, RS1, RS2, RS3 and RS4, respectively). The feeding period lasted 42 days.3. Performance parameters including feed consumption, feed conversion, body weight gain and percentage of abdominal fat at d 42 of age, nutrient retention (including dry matter, fat, total starch and nitrogen free extract), and apparent metabolisable energy was measured from d 18 to 20 and d 39 to 41 and showed negative linear responses to increasing dietary RS level (P < 0.05). Birds fed the RS3 and RS4 diets showed higher relative weight of duodenum, jejunum and ileum, as well as lower villus height and villus height/crypt depth compared to the control (P < 0.05). The activity of pancreatic trypsin of birds at d 21 and 42 of age decreased linearly in response to the increase of dietary RS level (P < 0.01). There were linear changes in up-regulated mRNA expression of SGLT-1 and down-regulated mRNA expression of GLUT-2 with increasing proportion of RS at d 21 and 42 of age (P < 0.05), respectively.4. It was concluded that feeding broilers with diets containing higher concentrations of RS impaired the development of small intestine, which resulted in lower apparent total tract retention of nutrients and poorer body weight gain, feed efficiency and carcass traits of broiler chickens.

Abstract
1. The aim of this study was to determine the effect of dietary taurine supplementation on growth performance, meat quality and antioxidant responses in breast muscle of broiler chickens.2. A total of 72 Arbor Acres broiler chickens (28-day-old) with similar body weight were randomly allocated into two groups, and fed either 0 g/kg (control; C) or 5 g/kg taurine-supplemented diets (TS) for 14 days.3. The results showed that TS had no effect on growth performance or chemical composition of breast muscle in broilers. The drip and cooking losses were significantly decreased (P < 0.05), and the pH24h of breast muscle were increased (P < 0.05) in the TS group. Meanwhile, broilers in the TS group exhibited significantly higher (P < 0.05) scavenging activities of superoxide and 2,2-diphenyl-1-picrylhydrazyl radicals, and lower (P < 0.05) contents of carbonyl, malondialdehyde, and 4-hydroxynonenal. TS increased (P < 0.05) total antioxidant capacity and superoxide dismutase activities. Moreover, TS significantly upregulated (P < 0.05) the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase 1, NAD(P)H quinone dehydrogenase 1, superoxide dismutase, catalase, and glutathione peroxidase.4. These findings suggested that TS enhanced antioxidative capacity and improved breast meat quality of broilers via activating the Nrf2 pathway.

Abstract
OBJECTIVE To explore the role of hsa-miR-203 in fracture healing and its underlying mechanism. PATIENTS AND METHODS Expression levels of hsa-miR-203 and PBOV1 in patients with hand fractures and intra-articular fractures after treatment were detected by quantitative Real-Time-Polymerase Chain Reaction (qRT-PCR). Viability and apoptosis of osteoblast cell line hFOB1.19 after hsa-miR-203 overexpression or knockdown were detected by cell counting kit-8 (CCK-8) assay and flow cytometry, respectively. The target gene of hsa-miR-203 was predicted by bioinformatics and verified by dual-luciferase reporter gene assay. Rescue experiments were conducted to further verify whether hsa-miR-203 could participate in fracture healing via PBOV1. RESULTS No significant hsa-miR-203 expression was found in patients with hand fractures and intra-articular fractures after treatment for 7 days, which was remarkably upregulated on the 14th day. PBOV1 expression was gradually downregulated as treatment time prolongation. Overexpression of hsa-miR-203 decreased cell viability, but induced apoptosis of hFOB1.19 cells. Bioinformatics predicted that PBOV1 might be the target gene of hsa-miR-203, which was further verified by dual-luciferase reporter gene assay. The effect of hsa-miR-203 on viability and apoptosis of hFOB1.19 cells was reversed after the PBOV1 knockdown. CONCLUSIONS Hsa-miR-203 inhibits fracture healing by regulating osteoblast viability and apoptosis via targeting PBOV1.

Abstract
OBJECTIVE To investigate the effect and related mechanisms of miR-485-5p on the osteogenic differentiation of rat bone marrow mesenchymal stem cells (BMSCs). PATIENTS AND METHODS The expression level of miR-485-5p was detected in clinical cases and during the osteogenic differentiation. Three group were established to study the potential function between miR-485-5p and osteogenic differentiation: miR-NC group (negative control), miR-485-5p mimics (BMSCs transfected by miR-485-5p mimics), and mimics + si-Osx (BMSCs transfected by miR-485-5p mimics and si-Osx), after the induction of osteogenic differentiation, the cell viability of BMSCs and osteogenic markers were determined. RESULTS In our work, miR-485-5p was found up-regulated in patients with osteoporosis by comparing with health cases. Besides, during osteogenic differentiation, miR-485-5p was suppressed. These results suggest miR-485-5p has a negative regulating effect. To research potential target of miR-485-5p, we checked it in three publicly available algorithms, TargetScan, miRDB and microRNA. We found that Osterix (Osx) is a direct target of miR-485-5p, and Luciferase assays confirmed our hypothesis, the subsequent experiments showed that decreased expression of Osx resulting from the up-regulation of miR-485-5p could restrain the cell viability and the expression level of osteogenic markers CONCLUSIONS: Our research revealed the promote function of miR-485-5p on osteoporosis, indicating that miR-485-5p could be a potential therapeutic strategy for the treatment of osteoporosis.

Abstract
Objective: To determine the factors affecting distribution and magnitude of antibody detection value in myasthenia gravis (MG). Methods: A total of 406 MG patients diagnosed at Department of Neurology, Peking University First Hospital from May 2015 to November 2017 were included.All of them exhibited muscle fatigue with decreased response in repetitive nerve stimulation test. There were 200 males and 206 females whose ages ranged from 2 to 85 years old. According to clinical classification of MG recommended by Myasthenia Gravis Foundation of America (MGFA), patients assigned to class I to class V included 200,140, 46, 15 and 5 cases, respectively. There were 33 cases of thymic hyperplasia and 63 cases of thymoma confirmed by radiological or pathological findings. Quantile plots and quantile regression model were used to determine the effects of age, gender and MGFA classification, thymus disease on acetylcholine receptors (AChR)antibody, acetylcholinesterase (AChE) antibody, Titin antibody, ryanodine receptor (RyR) antibody and muscle-specific tyrosine kinase (MuSK) antibody detection values detected by enzyme-linked immunosorbent assay (ELISA). Results: MGFA classification had effects on distribution of AChR antibody level. There was a positive correlation between age and AChR antibody level(P<0.05). Negative correlation was found between age and AChE, Titin and RyR antibody level (P<0.05). No significant correlation was shown between any factors and MuSK antibody level(P≥0.05). MGFA classification had a positive correlation with AChR antibody level (P<0.05) and no correlation with other antibody levels (P>0.05). Gender and thymus disease had no correlation with any tested antibody levels (P>0.05). Conclusion: MGFA classification has significant effects on distribution of AChR antibody level. Age and MGFA classification have positive correlation with AChR antibody level.

Abstract
Abstract
Background
Emergency dialysis is defined as a first dialysis session performed within 24 hours after the nephrologist’s assessment due to a life-threatening risk. Starting dialysis in emergency (ES) is associated with poorer outcomes compared to a planned start (PS). The aim of this study was to compare the pre-dialysis care trajectory between ES and PS patients.
Methods
Patients ≥ 18 years old who started dialysis in 2015 in France were included. Data from REIN were linked with the French national health database (SNDS). Individual characteristics at dialysis initiation, inpatient stays (number, duration and diagnosis), and consultations with general practitioners (GP) and nephrologists during the year before dialysis start were compared between ES and PS patients, as well as with national clinical practice guidelines.
Results
Among 8964 patients included, 30.6% started dialysis in emergency. These patients had more comorbidities than PS patients (19% of ES patients had 3 or more cardiovascular diseases versus 12.6% of PS patients, p < 0.001). In the year before dialysis start, ES patients had a lower median number of inpatient stays (1 versus 2 for PS patients, p = 0.001) but had a longer mean duration of hospital stay (8.1 days versus 5.8 days for PS patients, p < 0.001). ES patients had less consultations with a nephrologist (2.5 versus 4.5 for PS patients, p < 0.001). However, the number of GP consultations was not different between the two groups (9.7 versus 9.4 for PS patients, p < 0.064).
Conclusions
Nearly 1 in 3 patients started dialysis in emergency with more comorbidities at baseline than PS patients. Their one year pre-dialysis care trajectory was characterized by less frequent nephrological follow-up and a similar GP follow up, compared with PS patients. These results raise questions regarding access to coordinated care associating GPs and nephrologists. This issue of coordination will be investigated using qualitative methods.

Abstract
Abstract
Background
The evaluation of geographical healthcare accessibility in residential areas provides crucial information to public policy. This work developed an improved indicator: the Index of Spatial Accessibility (ISA) to measure geographical healthcare accessibility at the smallest available infra-urban level, that is, the Îlot Regroupé pour des Indicateurs Statistiques.
Methods
This study was carried out in the department of Nord, France. Healthcare professionals are geolocalized using postal addresses available on the French state health insurance website. ISA is derived from Enhanced Two-Step Floating Catchment Area (E2FCA) algorithm. We have constructed a catchment for each healthcare provider, by taking into account residential building centroids, car travel time as calculated by Google Maps and the edge effect. Principal Component Analyses (PCA) were used to build a composite ISA to describe the global accessibility of different kinds of health professionals.
Results
We applied our method to studying geographical healthcare accessibility for pregnant women, by selecting three types of healthcare provider: general practitioners, gynecologists and midwives. A total of 3587 healthcare providers are potentially able to provide care for inhabitants of the department of Nord. On average there are 92 general practitioners, 22 midwives and 21 gynecologists per 100,000 residents. The composite ISA for the three types of healthcare provider is 39 per 100,000 residents.
Conclusions
ISA is a multidimensional and improved measure, which combines the volume of services relative to population size with the proximity of services relative to the population’s location, available at the smallest feasible geographical scale. It could guide policy makers towards highlighting critical areas in need of more healthcare providers, and these areas should be earmarked for further knowledge-based policy making.
Key messages
Indicator of healthcare access at fine spatial scale allows us to identify precisely critical areas where healthcare professionals need to be allocated. ISA is a multidimensional measure, which combines the volume of services relative to population size with the proximity of services relative to the population’s location.

Abstract
The NOvA experiment has seen a 4.4σ signal of ν[over ¯]_{e} appearance in a 2 GeV ν[over ¯]_{μ} beam at a distance of 810 km. Using 12.33×10^{20} protons on target delivered to the Fermilab NuMI neutrino beamline, the experiment recorded 27 ν[over ¯]_{μ}→ν[over ¯]_{e} candidates with a background of 10.3 and 102 ν[over ¯]_{μ}→ν[over ¯]_{μ} candidates. This new antineutrino data are combined with neutrino data to measure the parameters |Δm_{32}^{2}|=2.48_{-0.06}^{+0.11}×10^{-3} eV^{2}/c^{4} and sin^{2}θ_{23} in the ranges from (0.53-0.60) and (0.45-0.48) in the normal neutrino mass hierarchy. The data exclude most values near δ_{CP}=π/2 for the inverted mass hierarchy by more than 3σ and favor the normal neutrino mass hierarchy by 1.9σ and θ_{23} values in the upper octant by 1.6σ.

Abstract
Exposure to ionizing radiation (IR) causes severe injuries to the human body, and normal tissue toxicity also limits the further application of cancer radiotherapy. However, current clinically used radioprotective agents are difficult to produce satisfactory effects. Toll-Like receptor (TLR) is a kind of pattern recognition receptor (PRR) that has been extensively studied for radioprotection in recent years. Several TLR family members are closely related to radioprotection. In cultured cells, TLR2, TLR5 or TLR9 agonist was proved to inhibit radiation-induced apoptosis and increase cell survival. TLR5 ligand CBLB502 was reported to alleviate bone marrow and intestinal injuries in mice and rhesus monkeys. Activation of TLR4 by its agonist LPS can protect bone marrow damage and lower mice mortality after irradiation. TLR9 ligand also exhibited protective effects on mid jejunum. Moreover, some kinds of TLR agonists, such as TLR2/6 co-agonist CBLB613, were reported to be more effective in radioprotection than single TLR agonist. In conclusion, TLRs and their ligands provide novel strategies for radiation protection in nuclear accidents as well as protection of normal tissues during cancer radiotherapy.

Abstract
BACKGROUND AND PURPOSE White matter hyperintensities on T2-weighted MR imaging are typical in older adults and have been linked to several poor health outcomes, including cognitive impairment and Alzheimer disease. The presence and severity of white matter hyperintensities have traditionally been attributed to occlusive arteriopathy, but recent evidence also implicates deep medullary venule collagenosis and associated vasogenic edema. Historically, postmortem analyses have been the sole way to analyze cerebral veins, but SWI can be now used to examine cortical veins in vivo. The aim of the current study was to determine whether there is an association between the diameters of the large draining cerebral veins/sinuses and white matter hyperintensity volume. MATERIALS AND METHODS T2-weighted FLAIR and SWI were performed in 682 older adults without dementia (mean age, 73.9 ± 5.9 years; 59.1% women). Total and regional white matter hyperintensity volume was derived. We measured the diameters of 5 regions of the cerebral venous draining system: internal cerebral veins, basal veins of Rosenthal, superior sagittal sinus, vein of Galen, and straight sinus terminus. RESULTS Increased diameter of the internal cerebral veins was associated with greater total white matter hyperintensity volume (β = 0.09, P = .02) and regionally in the parietal (β = 0.10, P = .006), frontal (β = 0.09, P = .02), and temporal (β = 0.09, P = .02) lobes. Increased diameter of the basal veins of Rosenthal was associated with greater total (β = 0.10, P = .01), frontal (β = 0.11, P = .003), and temporal (β = 0.09, P = .02) white matter hyperintensity volume. CONCLUSIONS Our results suggest that the caliber of the internal cerebral veins and of the basal veins of Rosenthal relates to regional white matter disease.

Abstract
This study evaluated the effects of dietary guanidinoacetic acid (GAA) supplementation on growth performance, plasma variables, muscle energy status, glycolytic potential, and meat quality of broilers experiencing transport stress during the summer. A total of 320 28-day-old male Arbor Acres broilers were randomly allotted to 3 dietary treatments, including a GAA-free basal control diet (160 birds) and basal diet supplementation with 600 (80 birds) or 1,200 mg/kg (80 birds) GAA for 14 D. On the morning of day 42, after an 8-h fast, the birds fed basal diets were divided into 2 equal groups, and all birds in the 4 groups of 80 birds were transported according to the following protocols: 1) a 0.5-h transport of birds on basal diets (as a lower-stress control group), 2) a 3-h transport of birds on basal diets, and a 3-h transport of birds on basal diets supplemented with either 3) 600 or 4) 1,200 mg/kg GAA. The results revealed that dietary supplementation with GAA at 600 and 1,200 mg/kg for 14 D prior to slaughter did not affect growth performance, carcass traits, and most textural characteristics and chemical composition of the pectoralis major (PM) muscle (P > 0.05). In the GAA-free group, a 3-h transport increased the broiler live weight loss, elevated the plasma corticosterone concentration, decreased the plasma glucose concentration, muscle concentrations of ATP, creatine and energy charge value, increased the muscle AMP concentration and AMP/ATP ratio, and accelerated glycolysis metabolism, which resulted in inferior meat quality (lower pH and higher drip loss, P < 0.05). However, dietary addition of GAA at 1,200 mg/kg increased the mRNA expression of S-adenosyl-l-methionine: N-guanidino-acetate methyltransferase in the liver and creatine transporter in both the liver and PM muscle. It also elevated muscle concentrations of creatine and phosphocreatine (P < 0.05), which helps improve meat quality by ameliorating the 3-h transport-induced muscle energy expenditure and delaying anaerobic glycolysis of broilers.

Abstract
Objective: To analyze the microbiome of diabetic foot osteomyelitis (DFO) by means of metagenome sequencing and provide evidence for identification of pathogenic bacteria in DFO. Methods: A total of 5 patients (3 males and 2 females) with DFO hospitalized at the Department of Endocrinology and Metabolism, Nanfang Hospital, Southern Medical University were enrolled and infected bone specimens were obtained between September 2016 and April 2017. The mean age was (55.8±9.5) years. Metagenome sequencing was performed to explore the characteristics of microbiome, and compared with the results of 16S rRNA sequencing. Results: The results of metagenome sequencing showed that DFO contained diverse microorganism. Totally, 22 dominant species were obtained, Klebsiella pneumoniae (69.66%) was the most abundant, followed by Veillonella parvula (36.93%) and Prevotella intermedia (34.19%). Compared with the 16S rRNA sequencing, metagenome sequencing could obtain more species information on the basis of fewer samples. At the genus level, both sequencing techniques suggested the most dominant pathogen in DFO was anaerobe. All bone specimens had polymicrobial communities. Conclusions: More microecological diversity and abundance of DFO can be found by using metagenome sequencing. At the species level, more bacteria, even bacterial strains can be identified by metagenome sequencing. At the genus level, the most abundant bacteria is anaerobe, however, at the species level, it is facultative anaerobe.

Abstract
BACKGROUND Human umbilical cord mesenchymal stem cells (hUC-MSCs) are potential candidates for treating retinal degeneration (RD). OBJECTIVE To further study the biology and therapeutic effects of the hUC-MSCs on retinal degeneration. METHODS Two hUC-MSC subpopulations, termed hUC-MSC1 and hUC-MSC2, were isolated by single-cell cloning method and their therapeutic functions were compared in RCS rat, a RD model. RESULTS Although both subsets satisfied the basic requirements for hUC-MSCs, they were significantly different in morphology, proliferation rate, differentiation capacity, phenotype and gene expression. Furthermore, only the smaller, fibroblast-like, faster growing subset hUC-MSC1 displayed stronger colony forming potential as well as adipogenic and osteogenic differentiation capacities. When the two subsets were respectively transplanted into the subretinal spaces of RCS rats, both subsets survived, but only hUC-MSC1 expressed RPE cell markers Bestrophin and RPE65. More importantly, hUC-MSC1 showed stronger rescue effect on the retinal function as indicated by the higher b-wave amplitude on ERG examination, thicker retinal nuclear layer, and decreased apoptotic photoreceptors. When both subsets were treated with interleukin-6, mimicking the inflammatory environment when the cells were transplanted into the eyes with degenerated retina, hUC-MSC1 expressed much higher levels of trophic factors in comparison with hUC-MSC2. CONCLUSION The data here, in addition to prove the heterogeneity of hUC-MSCs, confirmed that the stronger therapeutic effects of hUC-MSC1 were attributed to its stronger anti-apoptotic effect, paracrine of trophic factors and potential RPE cell differentiation capacity. Thus, the subset hUC-MSC1, not the other subset or the ungrouped hUC-MSCs should be used for effective treatment of RD.

Abstract
The next generation FFR Coronary Catheter includes a new stable pressure sensor, AD conversion at the tip of the catheter and mount of these components on the sidewall of the catheter instead of the guide wire enabling thus to use standard guide wires. The new ultrathin capacitive MEMS pressure sensor die with corresponding readout ASIC circuit offers better accuracy, robustness and automated assembly. The measured performance values of the fabricated chips correlate well with the simulated ones indicating comprehensive understanding of the sensor operation and control of the fabrication process. The test measurements outperformed the specifications for the FFR pressure sensing.

Abstract
BACKGROUND AND PURPOSE Low-density-lipoprotein-receptor-associated protein 4 (LRP4) autoantibodies have recently been detected in myasthenia gravis (MG), but little is known about the clinical characteristics associated with this serological type. In this study, the clinical features of Chinese patients with anti-LRP4 antibody-positive MG were characterized. METHODS A total of 2172 MG serum samples were collected from patients in various parts of China. An enzyme-linked immunosorbent assay was used to detect acetylcholine receptor (AChR) antibody and titin antibody, and cell-based assays were used to detect muscle-specific kinase antibody and LRP4 antibody. Clinical data for patients with MG were collected from different provinces in China. RESULTS In total, 16 (0.8%) patients with LRP4-MG were found amongst 2172 total patients, including three patients with AChR/LRP4-MG. Additionally, 13 (2.9%) patients with LRP4-MG were found amongst 455 patients with double seronegative MG. The ratio of males to females for these 13 patients was 1:1.6, and 53.8% patients were children. A total of 91.7% of cases exhibited initial ocular involvement, and 58.3% of cases exhibited simple eye muscle involvement. Responses to acetylcholinesterase inhibitors and prednisone were observed. CONCLUSION The expanded sample confirmed that the positive rate of LRP4 antibodies in China is lower than that in western countries. Our results highlighted the differences between LRP4-MG and other antibody groups. Children and female patients with LRP4-MG have a higher prevalence, often involving the ocular muscles and limb muscles. The clinical symptoms are mild, and satisfactory responses to treatment are often achieved.

Abstract
AIMS To investigate the associations among heteroplasmy levels (i.e. the proportions of mutant and wild-type mitochondrial DNA in the same cell), mitochondrial function and clinical severity of the m.3243A>G mutation. METHODS A total of 17 participants carrying the m.3243A>G mutation and 17 sex- and age-matched healthy controls were included in this study. Heteroplasmy levels of the m.3243A>G mutation in leukocytes, saliva and urine sediment were determined by pyrosequencing. The clinical evaluation included endocrinological, audiological and ophthalmological examinations. Mitochondrial function was determined in peripheral blood mononuclear cells isolated from participants. RESULTS Heteroplasmy levels in urine sediment were higher than those in leukocytes and saliva. Reduced levels of adenosine triphosphate and mitochondrial membrane potential, and increased reactive oxygen species production were observed in mutant peripheral blood mononuclear cells (all P < 0.05). Linear regression analysis indicated that higher heteroplasmy levels in peripheral blood leukocytes were associated with increased levels of glycated albumin and HbA1c , and decreased total hip bone mineral density T-score after adjustment for age and sex (all P < 0.05). Furthermore, mitochondrial membrane potential was independently associated with bone mineral density T-score at the femoral neck (P < 0.05). CONCLUSIONS Heteroplasmy levels in peripheral blood leukocytes and mitochondrial membrane potential in peripheral blood mononuclear cells were closely associated with clinical manifestations and were valuable for evaluation of the clinical severity of the m.3243A>G mutation.

Abstract
Gastric cancer is one of the most common malignant tumor worldwide and has high morbidity and mortality. microRNAs are small, non-coding RNAs which play critical roles in the post-transcriptional regulation of gene expression. In this current study, we used qRT-PCR to detect miR-215 and FOXO1 expression level in 50 paired gastric cancer tissues and found that miR-215 was frequently overexpressed and FOXO1 was down-regulated in GC cancer tissues. Clinicopathological analysis showed that miR-215 expression level was correlated with the progression of tumor invasion and TNM stage. Additionally, transwell invasion assay showed that miR-215 promoted the migration and invasion of gastric cancer cells. We found that miR-215 decreased FOXO1 expression by directly binding to the 3'-untranslated region (UTR) of FOXO1. These results suggest that miR-215 promotes cell migration and invasion of gastric cancer by targeting FOXO1. Therefore, this study provides a promising therapeutic strategy for treating gastric cancer.

Abstract
We report the first experimental results on spin-dependent elastic weakly interacting massive particle (WIMP) nucleon scattering from the XENON1T dark matter search experiment. The analysis uses the full ton year exposure of XENON1T to constrain the spin-dependent proton-only and neutron-only cases. No significant signal excess is observed, and a profile likelihood ratio analysis is used to set exclusion limits on the WIMP-nucleon interactions. This includes the most stringent constraint to date on the WIMP-neutron cross section, with a minimum of 6.3×10^{-42} cm^{2} at 30 GeV/c^{2} and 90% confidence level. The results are compared with those from collider searches and used to exclude new parameter space in an isoscalar theory with an axial-vector mediator.

Abstract
BACKGROUND Age-related macular degeneration (AMD) is the main cause of irreversible blindness in the elderly. Oxidative stress in retinal pigment epithelium (RPE) is deemed to play a pivotal role in the pathogenesis of AMD. miR-25 functions as an essential modulator in response to oxidative-stress in several cell types, but its function in RPE cells is poorly understood. OBJECTIVE To explore the roles of miR-25 in RPE cells and in the development of AMD. METHODS A rat model of retinal degeneration was induced by sodium iodate (SI). Subretinal injection of antagomiR-25 was performed for the intervention while the scramble as control. Visual responses were recorded with Electroretinogram (ERG). TUNEL assay was performed to detect apoptosis. Phagosome quantification in vivo was performed to evaluate RPE cell function. Oxygen-glucose deprivation treatment was performed to mimic in vitro oxidative stress. Gene expression at mRNA level and protein level were performed by quantitative polymerase chain reaction (qPCR) and Western Blot, respectively. The pigment epithelium derived factor (PEDF) level in the cultured medium was measured by Enzyme-linked immunosorbent assay (ELISA). The interaction between miR-25 and integrin αV (IGTAV) / PEDF 3'UTR was examined by dual luciferase assay. Chromatin immunoprecipitation (ChIP) assay was performed to examine its transcriptional regulation of miR-25. RESULTS Oxidative stress up-regulated miR-25 in RPE cells in very early stage, accompanied by decreased phagocytosis and reduced growth factor secretion in those cells. Such changes preceded RPE cell apoptosis and visual impairment in the SItreated rats. Furthermore, antagomiR-25 intervention effectively rescued RPE cells from degeneration in such model. The increased miR-25 was confirmed to mediate RPE degeneration through direct targeting IGTAV and PEDF. On the other hand, upstream, miR-25 was found to be up-regulated by STAT3 signaling under oxidative stress in both in vivo and in vitro models. CONCLUSION Our findings demonstrate that, in SI-treated rats, oxidative stress activates STAT3 signaling which up-regulates miR-25 expression, in a very early stage. The increased miR-25 then inhibits ITGAV and PEDF expressions, resulting in RPE phagocytosis dysfunction and then RPE apoptosis and visual impairment as observed in patients with AMD. These findings lead us to a better understanding of AMD pathogenesis, and suggest that miR-25 could be a potential therapeutic target for oxidative stress related RPE diseases, like AMD.

Abstract
Objective: To analyze the trends on constituent ratio of non-ST-segment-elevation (NSTEMI) and ST-segment-elevation myocardial infarction (STEMI) and related in-hospital mortality in acute myocardial infarction (AMI) patients hospitalized in Beijing Anzhen Hospital from 2004 to 2014. Methods: This is a single-center, retrospective study. We reviewed all patients hospitalized for AMI in Beijing Anzhen Hospital from January 1 2004 to December 31 2014, and collected all related information including hospitalization stay, the type of AMI, revascularization and in-hospital mortality. We analyzed the trends of constituent ratio of NSTEMI and STEMI, and their in-hospital mortalities during the 11 years. Results: Data from a total of 23 864 patients with AMI, including 5 539 STEMI and 18 325 NSTEMI, were analyzed. Compared with STEMI patients, NSTEMI patients were older, less likely to be male (P<0.001), had higher prevalence of hypertension, hyperlipidemia, diabetes (P<0.001), and lower prevalence of smoking (P<0.001). Additionally, patients with NSTEMI were more likely to have prior history of MI (12.6% (695/5 539) vs. 7.4% (1 354/18 325), P<0.001) and coronary artery bypass graft surgery (2.7% (152/5 539) vs. 0.7% (124/18 325), P<0.001). The constituent ratio of NSTEMI was significantly increased during the observation period, rising from 15.8% (107/802) in 2004 to 35.7% (1 273/3 583) in 2014 (P value for trend <0.001). The in-hospital mortality of NSTEMI patients was significantly lower compared with those with STEMI (1.84% (102 cases) vs. 2.74% (502 cases), P<0.001). The mortality of both STEMI and NSTEMI were significantly decreased during the 11 years (both P value for χ(2) trend test <0.001). After adjusting for other risk factors, NSTEMI was independently associated with lower in-hospital mortality (OR=0.50, 95%CI 0.40-0.63, P<0.001). Conclusions: In patients with AMI, the constituent ratio of NSTEMI versus STEMI is increased during the 11 years. The in-hospital mortality is decreased for both STEMI and NSTEMI patients in the past 11 years, and the in-hospital mortality rate of NSTEMI patients is lower than STEMI patients in this patient cohort during the observation period.

Abstract
During its orbit around the four million solar mass black hole Sagittarius A* the star S2 experiences significant changes in gravitational potential. We use this change of potential to test one part of the Einstein equivalence principle: the local position invariance (LPI). We study the dependency of different atomic transitions on the gravitational potential to give an upper limit on violations of the LPI. This is done by separately measuring the redshift from hydrogen and helium absorption lines in the stellar spectrum during its closest approach to the black hole. For this measurement we use radial velocity data from 2015 to 2018 and combine it with the gravitational potential at the position of S2, which is calculated from the precisely known orbit of S2 around the black hole. This results in a limit on a violation of the LPI of |β_{He}-β_{H}|=(2.4±5.1)×10^{-2}. The variation in potential that we probe with this measurement is six magnitudes larger than possible for measurements on Earth, and a factor of 10 larger than in experiments using white dwarfs. We are therefore testing the LPI in a regime where it has not been tested before.

Abstract
To investigate the alleviative effects and molecular mechanisms of taurine supplementation on growth performance and carcass characteristics in broilers exposed to chronic heat stress, 144 male Arbor Acres broilers (28 d old) were randomly distributed to positive control (PC, 22°C, basal diet), heat stress (HS, consistent 32°C, basal diet), or heat stress + taurine (HS + T, consistent 32°C, basal diet + 5.00 g/kg taurine) groups, with 6 cages per group and 8 birds per cage. Chronic heat stress significantly decreased body weight, average daily gain, and average daily feed intake, and increased cloacal temperature and feed conversion ratio (FCR, P < 0.05). Though taurine supplementation tended to decrease the FCR in the HS + T group compared with the HS group after 14 d of heat exposure (P = 0.071), there were no significant alleviative effects of taurine supplementation on the increased cloacal temperature and decreased growth performance in chronic heat-stressed broilers (P > 0.05). After 7 and 14 d of heat exposure, taurine supplementation significantly increased the proportion of breast muscle and hormone-sensitive lipase activity in the abdominal fat (P < 0.05), and decreased the mRNA expressions of muscle atrophy F-box protein (MAFbx) and muscle ring-finger protein-1 (MuRF1) in breast muscle compared with the HS group (P < 0.05). After 7 d of heat exposure, taurine supplementation significantly increased serum non-esterified fatty acid concentration (P < 0.05), and decreased the mRNA expressions of acetyl-CoA carboxylase 1c (ACC) and muscular isoform of carnitine palmitoyl transferase 1 (M-CPT1) compared with the HS group (P < 0.05). In addition, the mRNA expressions of M-CPT1 and ribosomal protein S6 kinase, 70 kDa (p70S6K) in the HS + T group were significantly higher than those of the other two groups after 14 d of heat exposure (P < 0.05). In conclusion, taurine supplementation can improve carcass characteristics of chronic heat-stressed broilers by facilitating lipolysis for energy, enhancing protein synthesis, and suppressing protein degradation of the breast muscles.

BACKGROUND AND PURPOSE The aim of this study was to examine the association amongst remote diffusion-weighted imaging lesions (R-DWILs), imaging markers of cerebral small vessel disease (cSVD) and total cSVD burden in patients with primary intracerebral haemorrhage (ICH). METHODS In total, 344 consecutive primary ICH patients were enrolled prospectively. R-DWILs on magnetic resonance imaging as well as four imaging markers of cSVD, including cerebral microbleeds (CMBs), white matter hyperintensities (WMHs), lacunes and enlarged perivascular spaces, were rated with validated scales. The total cSVD score was calculated by adding up these four markers. Univariate and multivariate analyses were performed. RESULTS Remote DWI lesions were detected in 57 (16.6%) primary ICH patients. On multivariate logistic regression analysis, the presence of CMBs [odds ratio (OR) 5.26, 95% confidence interval (CI) 1.72-16.12], of high-grade WMHs (OR 4.68, 95% CI 2.01-10.90), the presence of lacunes (OR 2.69, 95% CI 1.20-6.06), mixed CMBs (OR 2.93, 95% CI 1.35-6.36), mixed lacunes (OR 3.60, 95% CI 1.25-10.37), periventricular WMHs (OR 2.19, 95% CI 1.40-3.44), deep WMHs (OR 1.92, 95% CI 1.24-2.97) and total WMHs (OR 1.52, 95% CI 1.20-1.94) were associated with the presence of R-DWILs. A significant association was also found between high-grade total cSVD score and R-DWILs (OR 1.97, 95% CI 1.36-2.84). This association remained significant in patients stratified by an age of 60 years or more than 60 years. CONCLUSIONS Remote DWI lesions are correlated with the severity of each imaging marker of cSVD and with the total burden of cSVD.

Abstract
The aim of this study was to investigate the effects of dietary crude protein levels and cysteamine (CS) supplementation on meat quality and related indices in longissimus dorsi muscle of finishing pigs. One hundred and twenty barrows were randomly allocated to a 2 × 2 factorial arrangement with five replicates of six pigs each. The primary variations were crude protein levels (14% or 10%) and CS supplemental levels (0 or 140 mg kg−1). After 41 d, 10 pigs per treatment were slaughtered. The results showed that low-protein level diets (LPDs) decreased Warner–Bratzler shear force (P < 0.01) and increased the content of intramuscular fat (P < 0.01). The mRNA expressions of lipogenic genes were up-regulated (P < 0.01), and the mRNA expressions of lipolytic genes were down-regulated (P < 0.01) in pigs fed LPD. LPDs increased the mRNA expressions of μ-calpain, and decreased the mRNA expression of calpastatin (P < 0.01). In addition, CS supplementation increased the mRNA expression of μ-calpain (P < 0.01). In conclusion, LPD improved the meat quality probably through regulating the lipogenesis, lipolysis, and the proteolysis process in muscle. The CS supplementation did not affect the meat quality of finishing pigs. Moreover, no significant interaction between dietary protein levels and CS supplementation for the meat quality of finishing pigs was observed.

Abstract
We present first results on the scalar coupling of weakly interacting massive particles (WIMPs) to pions from 1 t yr of exposure with the XENON1T experiment. This interaction is generated when the WIMP couples to a virtual pion exchanged between the nucleons in a nucleus. In contrast to most nonrelativistic operators, these pion-exchange currents can be coherently enhanced by the total number of nucleons and therefore may dominate in scenarios where spin-independent WIMP-nucleon interactions are suppressed. Moreover, for natural values of the couplings, they dominate over the spin-dependent channel due to their coherence in the nucleus. Using the signal model of this new WIMP-pion channel, no significant excess is found, leading to an upper limit cross section of 6.4×10^{-46} cm^{2} (90% confidence level) at 30 GeV/c^{2} WIMP mass.

Abstract
BACKGROUND In the West, the safety and efficacy of the Lotus valve have been demonstrated; however, data in the Chinese population are still lacking. Few studies have compared the clinical outcomes of transcatheter aortic valve replacement (TAVR) with the Lotus valve in patients with bicuspid or tricuspid aortic valve stenosis. Our aim was to assess TAVR outcomes with the Lotus aortic valve in a Chinese patient cohort. METHODS In total, 23 symptomatic, high-surgical risk patients with severe aortic valve stenosis were enrolled. Among them, nine patients (39%) had bicuspid aortic valves, and three patients had a large annulus dimension. The Lotus valve was successfully implanted in all patients. To facilitate accurate positioning, partial re-sheathing was attempted in ten patients (43.5%), while one patient had a full retrieval. One-year clinical follow-up was completed in all patients. RESULTS There were no deaths, strokes, or major adverse cardiac and cerebrovascular events in 22 of the 23 patients at 30 days; the all-cause mortality rate at 1 year was 4.4% (1 of 23 patients). The mean aortic valve gradient decreased from 51.5 ± 8.8 mm Hg at baseline to 13.4 ± 4.9 mm Hg (p < 0.001) and the valve area increased from 0.6 ± 0.2 cm2 to 1.5 ± 0.4 cm2 (p < 0.001) at 30 days. Paravalvular leakage was absent or mild (22%), and no patient had severe paravalvular leakage. Six patients (26.1%) required a postprocedural pacemaker. There was no difference regarding the procedural and the 1‑year outcomes between patients with bicuspid and tricuspid aortic valve stenosis. CONCLUSION Our single-center experience demonstrated that the Lotus valve is feasible and effective for Chinese patients with aortic valve stenosis, including atypical cases with bicuspid aortic valves or large aortic annulus size.

Abstract
Background. The acute respiratory distress syndrome (ARDS) is a condition with a high mortality and morbidity. Mechanical ventilation prevents immediate mortality but may further damage patients' lungs. Low tidal volume lung-protective strategies have been shown to increase survival by reducing this iatrogenic damage. Current guidelines recommend tidal volumes of 6-8 ml kg -1 of predicted body weight. We used data from three large randomized controlled trials of treatments for ARDS to determine compliance with these recommendations. Methods. We used the tidal volume recorded at randomization for all patients in the OSCAR, HARP-2, and BALTI-2 studies. In addition, we used the ventilation data for control arm patients in OSCAR and all patients in HARP-2 at days 1 and 7 after randomization. Results. The three trials enrolled 1660 patients, with tidal volume data available at least at one time point in 1412 patients. Compliance with the 6-8 ml kg -1 recommendation for tidal volume ranged from 20 to 39% of patients across all time points in all three trials. Conclusion. Poor compliance with the guidelines for tidal volume in patients with ARDS has been demonstrated before in case series, but not in clinical trials where the patient population is specifically selected against standard ARDS diagnostic criteria and the investigators were encouraged to use low tidal volumes. This study may indicate a need to improve implementation and compliance with protective lung ventilation.
