Abstract	BACKGROUND Groundwater is closely related to surface water. Groundwater over-extraction has triggered a series of negative ecological effects in the Daqing River basin. The evolution of groundwater chemical characteristics is influenced by both natural and anthropogenic factors. The analysis of groundwater chemical characteristics can indicate the meteorological-hydrological and water-rock interaction during groundwater runoff, thus reflecting the groundwater circulation path, groundwater system characteristics and evolution laws, etc. It also helps to monitor groundwater dynamics and prevent the occurrence of groundwater pollution. OBJECTIVES To clarify the chemical characteristics and evolution of groundwater in the plain area of the Daqing River basin, which will be important for the rational development and utilization of water resources in the basin. METHODS 47 water samples from the shallow aquifer groups and 32 water samples from the deep aquifer groups were collected to analyze the main anions (Cl-, SO42-, NO3-) and cations (K+, Na+, Ca2+, Mg2+). The water chemistry characteristics and evolution laws were studied by using the water chemistry type, Gibbs model and ion ratio relationship. On-site portable water quality analyzer (HACH-HQ40d) was used to test pH (accuracy 0.01), total dissolved solids (TDS, accuracy 0.01) and other parameters, and groundwater samples were collected after the indicators were stabilized. All samples were sent to the laboratory at low temperature and stored in a refrigerator at 4℃, and groundwater alkalinity was determined by titration on the same day. Seven days later, the samples were sent to the Institute of Hydrogeology and Environmental Geology, Chinese Academy of Geological Sciences for testing of major anions (Cl-, SO42-, NO3-) and major cations (K+, Na+, Ca2+, Mg2+) using inductively coupled plasma-optical emission spectrometry (iCAP6300). The anion and cation charge balance error was less than 5%, and the anion and cation test accuracy was 0.01mg/L. RESULTS The test ...

Abstract	The gel springiness of preserved egg during pickling is an important indicator of the maturity and gel quality of preserved eggs (PEs), for which there are no validated rapid means of detection. This work, hyperspectral imaging was used to non-destructively detect the gel springiness of preserved eggs (PEs) at different maturity levels during the curing period. Firstly, principal component analysis was used to explain the characteristics of the changes in gel springiness during the curing process of PEs of different maturity levels. Secondly, based on two-dimensional correlation spectroscopy(2DCOS), the 427–843 nm band range was explored as the optimal study region for gel springiness when gel springiness was used as a perturbation factor. In turn, spectral factors representative of the change in gel springiness are stripped in this band region. Comparing three different variable selection methods (SPA、CARS and UVE), it was found that the UVE-PLSR model had the highest detection accuracy: The predicted coefficient of determination Rp2 and the predicted standard deviation SEp of the predicted gel springiness are 0.846 and 1.526, with a residual prediction deviation RPD of 2.35. Finally, the above optimal prediction model is applied to the pixel spectrum to calculate the springiness value of each pixel point on the hyperspectral image and is supplemented by a pseudo-color technique to visualize the prediction of the spatial distribution of the gel springiness value. The results show that using hyperspectral imaging can detect the gel springiness value of the PE during the curing process, which will provide a theoretical basis for future determination of the ripeness of the PE as well as high-throughput online sorting.

Abstract	Most of the existing deep learning methods for hyperspectral image (HSI) classification use pixel-wise or patch-wise classification. In this paper, we propose an image-wise classification method, where the network input is the original hyperspectral cube rather than the spectral curve of each pixel (i.e., pixel-wise) or neighbor region of each pixel (i.e., patch-wise). Specifically, we propose a minimalistic fully convolution network (MFCN) and a semi-supervised loss function, which can perform pixel-level classification for HSI with few labeled samples. The comparison experiments demonstrated the progress of our methods, using three new benchmark HSI datasets (WHU-Hi-LongKou, WHU-Hi-HanChuan and WHU-Hi-HongHu) with wavelength range from 400 to 1000nm. In the comparison experiments, we randomly selected 25 labeled pixels from each class for training, equivalent to only 0.11%, 0.16%, and 0.14% of all labeled pixels for the three datasets, respectively. In addition, through ablation studies and theoretical analysis, we verified and analyzed the effectiveness and superiority of our design choices.

Abstract	Background: The 2020 European Society of Cardiology guidelines do not recommend pretreatment for nonST-segment elevation myocardial infarction (NSTEMI) patients with unclear coronary anatomy, which is inconsistent with our routine preoperative approach to loading P2Y12 receptor inhibitors (e.g., preoperative loading of 300 mg of clopidogrel). Objectives: The purpose of our study was to compare the safety and effectiveness of P2Y12 inhibitors administered before coronary angiography or at least before percutaneous coronary intervention (PCI) with during or after PCI. Methods: Cochrane, PubMed, and Embase databases were searched. The primary effect endpoint and safety endpoint were any-cause death and major bleeding, respectively. Major adverse cardiovascular events, myocardial infarction and revascularization were also analyzed. Results: Our search identified 9 trials. P2Y12 inhibitor pretreatment was associated with lower death from any cause (OR 0.62, 95% CI 0.53-0.72, P < 0.00001) without increasing the risk of bleeding (OR 1.02, 95% CI 0.80-1.30, P = 0.89). However, prasugrel or ticagrelor pretreatment was not associated with a lower risk of mortality (OR 0.70, 95% CI 0.31-1.59, P = 0.40) and increased the risk of bleeding (OR 1.67, 95% CI 1.10-2.54, P = 0.02). Conclusions: In summary, clopidogrel pretreatment was associated with significantly lower mortality, major adverse cardiovascular events, myocardial infarction and revascularization with no increase in major bleeding. However, these advantages were not observed with prasugrel or ticagrelor pretreatment.

Abstract	Purpose: The change in the left atrial anteroposterior diameter (LAD) after radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) has become an independent factor in predicting the postoperative curative effect; however, whether the specific time point of this change is related to the postoperative curative effect is unclear. The purpose of this study was to explore the correlation between the specific time point of LAD change and the recurrence of AF 1 year after RFCA. Methods: Patients with AF who underwent RFCA in our hospital from July 2016 to May 2020 were enrolled in the study. The patients were divided into four groups according to the time point when the LAD decreased by 10% after RFCA: group A, first month after RFCA; group B, second month after RFCA; group C, third month after RFCA; group D, unchanged or changed > 3 months after RFCA. Results: In the multivariable Cox analyses, the duration of AF, LAD, and persistent AF were independent risk factors for the recurrence of AF. The recurrence rate of AF 1 year after RFCA were significantly lower in groups A (odds ratio [OR], 0.160; 95% confidence interval [CI]: 0.073-0.352; P < 0.001) and C (OR, 0.388; 95% CI: 0.156-0.963; P = 0.041) than in the control group. Conclusions: Reduction of LAD within 3 months after operation predicts the success rate of RFCA, with reduction within 1 month after operation having a higher success rate. This indicates the necessity of treatment in patients with AF who do not experience an early reduction in the LAD after RFCA.

Abstract	In the present study, we investigated face processing in individuals with self-reported Autism Spectrum Disorder (ASD, n = 16) and typically developing control participants (n = 16) using behavioural and electrophysiological measures. As a measure of their face memory, we administered the Cambridge Face Memory Test to participants in the ASD group. The results showed that the scores of the ASD participants were reliably below the age- and gender-matched norms of neurotypical individuals. To measure brain responses to faces, we used the fast periodic visual stimulation method, presenting photographs of a same-identity face (i.e., base face) at a constant frequency of 6 Hz (F) interleaved with different-identity faces (i.e., the oddball faces) presented at 1.2 Hz. The 6 Hz presentation of the base face and 1.2 Hz presentation of the oddball face elicited periodic brain responses corresponding to face detection and face individuation processes, respectively. Participants viewed four blocks of upright faces and four blocks of inverted faces. The results showed an enhanced EEG response to upright base faces at 6 Hz frequency and its harmonics compared to inverted faces, and the response was most focal over medial occipital channels. An enhanced response was found to upright oddball faces at 1.2 Hz and its harmonics compared to the inverted faces, and the response was centred over occipito-temporal channels in the right hemisphere. Critically, no differences or interactions were found between the ASD and typically developing groups in the responses to either the 6 Hz base faces or the 1.2 oddball faces. These results suggest that in individuals with ASD, the earlier stage of face perception, as measured by the fast periodic visual stimulation paradigm, can be dissociated from the later memory stage of face processing, as assessed by the Cambridge Face Memory Test.

Abstract	In atrial fibrillation (AF) patients, complex electrograms during sinus rhythm (C-EGMs) could be pathological or not. We aimed to demonstrate whether local pacing was helpful to discern pathological C-EGMs. 126 persistent AF patients and 27 patients with left-side accessory pathway (LAP) underwent left atrial mapping during sinus rhythm. If C-EGMs were detected, local pacing was performed. If the electrograms turned normal, we defined them as non-fixed C-EGMs, otherwise as fixed C-EGMs. No difference was detected in the incidence and proportion of non-fixed C-EGMs between AF patients and LAP patients (101/126 vs. 19/27, P = 0.26; 9.1 ± 6.0% vs. 7.7 ± 5.7%, P = 0.28). However, the incidence and proportion of fixed C-EGMs were higher in persistent AF patients (87/126 vs. 1/27, P < 0.01; 4.3 ± 3.4% vs. 0.1 ± 0.5%, P < 0.01). Compared with non-fixed C-EGMs, fixed C-EGMs had lower amplitudes, longer electrogram durations and longer Stimuli-P wave internals. All AF patients received circumferential pulmonary vein isolation. Among AF patients with fixed C-EGMs, 45 patients received fixed C-EGMs ablation and 42 patients underwent linear ablation. Compared with linear ablation, fixed C-EGMs ablation reduced recurrence (HR: 0.43; 95% CI 0.21-0.81; P = 0.011). Among patients without fixed C-EGMs ablation, the proportion of fixed C-EGMs was an independent predictor of ablation outcomes (HR for per percent: 1.13, 95% CI 1.01-1.28, P = 0.038). C-EGMs could be classified into fixed and non-fixed C-EGMs through local pacing. Fixed rather than non-fixed C-EGMs might indicate abnormal atrial substrates and fixed C-EGMs ablation improve outcomes of persistent AF ablation.

Abstract	Background: The optimal treatments for atrial fibrillation in heart failure patients are controversial. The present study compared the efficacy of catheter ablation and medical therapy in patients with atrial fibrillation and heart failure. Methods: Pubmed, Embase, Cochrane Library, and Web of Science were searched until January 15, 2022. Randomized controlled trials comparing catheter ablation for atrial fibrillation with medical therapy in patients with atrial fibrillation and heart failure were enrolled. Primary outcome was all-cause mortality. Secondary outcomes included the heart failure hospitalization and the change in left ventricular ejection fraction, 6-minute walk test distance, peak oxygen consumption, and Minnesota Living with Heart Failure questionnaire score. Results: Totally 8 randomized controlled trials involving 1693 patients were included. Compared with medical therapy, catheter ablation significantly reduced all-cause mortality (risk ratios=0.60, 95% Cl: 0.45 to 0.80, P < .001) and hospitalization due to heart failure (risk ratios=0.58, 95% Cl: 0.46 to 0.73, P < .001), improved left ventricular ejection fraction (mean difference=5.25%, 95% CI: 2.78% to 7.71%, P < .001), improved the performance of 6-minute walk test (mean difference=28.83 m, 95% CI: 8.61 to 49.05 m, P=.005), increased peak oxygen consumption (mean difference=3.11 mL/kg/min, 95% CI: 1.04 to 5.18 mL/kg/min, P=.003), and reduced Minnesota Living with Heart Failure score (mean difference=-8.45, 95% CI: -16.28 to -0.62, P=.03). Conclusion: In heart failure patients with atrial fibrillation, catheter ablation provides more benefits over medical therapy in the important clinical outcomes, exercise capacity, and quality of life.

Abstract	Background: The clinical treatment of coronary microvascular dysfunction (CMD) is mainly based on conventional medicine, but the mechanism of the medicine is single and the efficacy is different. Shenmai injection (SMI) has a variety of ingredients, but the effect of SMI on CMD has not been studied. This study investigated the effect of SMI on CMD and its possible mechanism. Methods: The protective effect of SMI on CMD was evaluated in Sprague-Dawley (SD) rats and human umbilical vein endothelial cells (HUVECs). In vivo, forty-five male SD rats were randomly divided into control group (sham group), CMD group (model group), and SMI group (treatment group). Two weeks after SMI intervention, laurate was injected into the left ventricle of rats to construct a CMD model. Blood samples were collected to detect myocardial enzymes, oxidative stress, and inflammatory factors, and the hearts of rats were extracted for histopathological staining and western blot detection. In vitro, a hydrogen peroxide-induced endothelial injury model was established in HUVECs. After pretreatment with SMI, cell viability, oxidative stress, vasodilative factors, and apoptosis were detected. Results: In vivo, pretreatment with SMI could effectively reduce the concentrations of lactate dehydrogenase (LDH), creatine kinase-MB (CK-MB), cardiac troponin I (cTnI), endothelin-1 (ET-1), tumor necrosis factor alpha (TNF- Conclusions: Pretreatment with SMI could improve CMD by alleviating oxidative stress, inflammatory response, and apoptosis and then improving vascular endothelial function and microvascular structure.

Abstract	In a standard center cueing paradigm, participants are asked to identify a target object presented either to the left or the right of a center cue (e.g., eye gaze, head-turn, arrow, etc.). When the center cue is non-predictive (e.g., the arrow points to the correct location of the target only 50 % of the time), the target can still be identified faster at the validly cued location than at the invalidly cued location. However, the abrupt onset of an object can elicit reflexive attention orientation. It is important to investigate whether this abrupt onset effect interferes with the cueing effect elicited by center cues because this interference effect, if it exists, should be controlled for in order to improve the test validity of the center cueing task. In an attentional cueing paradigm, we examined how the abrupt appearance of an exogenous target object mitigates the influence of center cues involving either a head turn (Experiment 1) or an arrow (Experiment 2). In Experiment 1, a non-predictive head-turn cue was followed by a target object (circle or square) presented in the left or right visual field. In the non-distractor condition, the target object was presented by itself. In this case, it is assumed that the sudden appearance of the target provides an orienting cue to the observer. To equalize the cueing effect of the target object, we presented a competing distractor object (triangle) in the opposite visual field to the target object. The participant's task was to categorize the target object as either a circle or square while ignoring the non-target triangle object in the opposite visual field. In Experiment 2, the arrow version of the cued recognition task was used, in which a single-headed arrow pointed to the object. The results from both experiments showed that both the non-predictive head-turn and arrow cues produced a reliable cueing effect in the distractor and non-distractor conditions. However, the magnitude of the cueing effect was greater in the distractor condition than in the non-distractor condition, suggesting that the abrupt onset of the target object acts like an exogenous signal, thereby reducing the impact of the internal head turn and arrow cues.
