Analysis of Audiences’ Attitudes towards Product Placement in Short Videos Based on Appraisal Theory: A Case Study of the Bilibili Platform
Authors: Deng Zhixin , Xie Baoying
Published: July 2022

Supported by the systemic functional linguistic theory, this paper analyzes and compares audiences’ attitudes toward nine types of product placement in short videos on Bilibili by using the “attitude” subsystem of the appraisal theory. This paper focuses on the distribution of attitude resources and the positive and negative affective directions of audiences’ evaluation of different types of product placement. It finds that the distribution of affect resources and appreciation resources varies among different types. In general, the proportion of appreciation resources is much higher than the other two resources. This study tries to analyze the reasons behind the distribution in the context of video characteristics, advertised products, and the contents of comments, to provide a reference for the standardization of product placement in short videos.
Evening Caffeine Did Not Improve 100-m Swimming Time Trials Performed 60 Min Post-Ingestion or the Next Morning After Sleep
Authors: Newbury Josh W. , Saunders Bryan , Gough Lewis A.
Published: July 2022

The potential ergogenic benefits of caffeine (CAF) are well known within the athletic community, often leading to its use in adolescent swimming cohorts to enhance their performance. However, it has previously been reported that CAF has sleep-disturbing effects, which could be detrimental to performance over consecutive days in multiday competitions. Moreover, the effects that evening CAF ingestion has on sleep, side effects, and next-day performances are yet to be researched in trained adolescents. In a double-blind, randomized, crossover design, eight national-level swimmers (age: 18 ± 1 years, height: 1.76 ± 0.06 cm, body mass [BM]: 69.4 ± 6.4 kg) ingested a capsule containing 3 mg/kg BM CAF or a placebo 60 min before an evening 100-m swimming time trial. The next morning, sleep was analyzed (Core Consensus Sleep Diary) and 100-m time trials were repeated. Side effects were analyzed via visual analog scales throughout the study. No differences were found for swimming performance (p = .911) in the evening (CAF: 59.5 ± 7.8 s, placebo: 59.9 ± 7.9 s, g = 0.06) or morning (CAF: 59.7 ± 7.7 s, placebo: 60.2 ± 7.9 s, g = 0.07). In addition, no group differences were found for any subjective side effects (e.g., anxiety: p = .468, tachycardia: p = .859, alertness: p = .959) or sleep parameters (e.g., sleep latency: p = .395, total sleep time: p = .574). These results question the use of a standardized 3 mg/kg BM CAF ingestion strategy for 100-m swimming time trials in trained adolescents, although objective measures may be needed to confirm that CAF does not affect sleep within this cohort.

Unleashing alkali feldspar: Ra/Th ages and chemical and isotopic constraints on Holocene phonolite magmatism, Canary Islands
Authors: Brown Bryce S. , Ramos Frank C. , Wolff John A. , Dorado Olaya , Martí Joan
Published: July 2022

Accurately dating phenocrysts in Holocene volcanic rocks poses many challenges but is critical to placing magmatic processes that occur prior to eruption into a temporal frame-work. We dated alkali feldspar (i.e., orthoclase Or10 to Or46) crystals in four young phonolites from the Teide–Pico Viejo volcanic complex, Tenerife (Spain), using (226Ra)/(230Th) isotopes. Partition coefficients of Ra (DRa) and DRa/DBa of feldspars were predicted using an approach based on the lattice strain model, which yielded crystallization ages that overlap or predate known eruption ages for the Lavas Negras (ca. 1 ka), Montaña Blanca (ca. 2 ka), Arenas Blancas (ca. 2–4 ka), and Teide H (ca. 6 ka) phonolites. Crystallization of feldspar may occur up to the time of eruption, with >8 ka crystals also present, possibly suggesting extended magma differentiation times. However, feldspars yielding finite (226Ra)/(230Th) ages are mostly in equilibrium with the groundmass, unlike >8 ka crystals, which were therefore identified as antecrysts/xenocrysts. The 87Sr/86Sr ratios of feldspars indicate that crystallization predated late-stage assimilation, affecting 87Sr/86Sr ratios of some melts. The (226Ra)/(230Th) ages also constrain the tempo of phonolite magma evolution on Tenerife. Integration of (226Ra)/(230Th) ages with feldspar major elements, trace elements, and isotopes provides a powerful means for investigating crystallization histories using a dominant mineral that controls the overall magmatic evolution of phonolites on thousand-year time scales.
Xenoliths reveal a hot Moho and thin lithosphere at the Cordillera-craton boundary of western Canada
Authors: Canil Dante , Russell J. Kelly
Published: July 2022

Properties of the lithosphere control the transitions in elevation and plate deformation from hot, mobile orogenic belts to cooler, stronger cratons. The sharp, abrupt boundary of the North American Cordillera with the craton in western Canada has been suggested to be a result of recent (<50 Ma) heating and delamination of the lithosphere. To test this, we queried the fine structure in the thermal history of the mantle lithosphere approaching this transition using mantle xenolith thermobarometry. The xenoliths sampled by their host lava within ~20 km of the Cordillera-craton boundary require thinner lithosphere (by 20 km) and a hotter Moho (by 200 °C) compared to those sampled 180 km away. A hot, weak lithosphere at the boundary explains a topographic low that parallels this transition for a large length of the North American Cordillera, possibly from focused heat during edge convection. The cooling pattern of geothermometers applied to the xenoliths also suggests that any delamination event producing thinner lithosphere in the orogen is unlikely to have occurred in the past 50 m.y.
Hikurangi megathrust slip behavior influenced by lateral variability in sediment subduction
Authors: Gase Andrew C. , Bangs Nathan L. , Van Avendonk Harm J.A. , Bassett Dan , Henrys Stuart A.
Published: July 2022

Subduction megathrusts exhibit a range of slip behaviors spanning from large earthquakes to aseismic creep, yet what controls spatial variations in the dominant slip mechanism remains unresolved. We present multichannel seismic images that reveal a correlation between the lithologic homogeneity of the megathrust and its slip behavior at a subduction zone that is world renowned for its lateral slip behavior transition, the Hikurangi margin. Where the megathrust exhibits shallow slow-slip in the central Hikurangi margin, the protolith of the megathrust changes ~10 km downdip of the deformation front, transitioning from pelagic carbonates to compositionally heterogeneous volcaniclastics. At the locked southern Hikurangi segment, the megathrust forms consistently within pelagic carbonates above thickened nonvolcanic siliciclastic sediments (unit MES), which subduct beyond 75 km horizontally. The presence of the MES layer plays a key role in smoothing over rough volcanic topography and establishing a uniform spatial distribution of lithologies and frictional properties that may enable large earthquake ruptures.
Extensive and ancient feldspathic crust detected across north Hellas rim, Mars: Possible implications for primary crust formation
Authors: Phillips Michael S. , Viviano Christina E. , Moersch Jeffrey E. , Rogers A. Deanne , McSween Harry Y. , Seelos Frank P.
Published: July 2022

Due to its size and observable record of ancient rock, Mars is key to understanding crustal formation on planetary bodies, including Venus and Earth, which may have derived their first stable crust from mantle-overturn melting. Recent evidence that ancient martian crust contains an evolved component supports inferences of a pervasive, buried feldspathic component to the crust. With data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), we searched for feldspathic lithologies in pre-Noachian (older than ca. 4.1 Ga) crustal blocks uplifted by the Hellas basin-forming impact. We present evidence for ancient feldspathic rocks exposed across an ~2200 × 600 km area north of Hellas. Given their pre-Noachian age and stratigraphic position directly above putative mantle material, it is possible that these outcrops represent martian primary crust. Our discovery supports the hypothesis that there exists a pervasive, subsurface feldspathic component to the martian crust—a hypothesis that has, until now, been supported only by inferences from geodynamic data and small-scale observations.

Grade 4 very severe hypertriglyceridaemia at diagnosis in a child with acute lymphoblastic leukaemia
Authors: Khera Sanjeev , Kapoor Ravi , Sunder Shyam , Mahajan Deepti
Published: July 2022

Dyslipidaemia is seen in nearly all cases of acute lymphoblastic leukaemia (ALL) at diagnosis, with mild hypertriglyceridaemia (HTG) in 61% and reduced high-density lipoprotein in 98% cases. HTG irrespective of severity is due to metabolic derangements associated with tumour cells turnover in haematological malignancies and is generally self-limiting. Very severe HTG with overt lipaemic serum is extremely rare at presentation in ALL. HTG is complicated by thrombosis, osteonecrosis and pancreatitis during induction chemotherapy for ALL with steroids and L-asparginase. A careful monitoring is required during induction chemotherapy in ALL when severe HTG is present at diagnosis. We present a female toddler with ALL, who presented with very severe HTG and grossly lipaemic serum. Her very severe HTG decreased to mildly raised HTG at the end of first week of induction chemotherapy. There was no further complication noticed during induction therapy.
Motor neuron disease mimics in practice: a case series
Authors: Aitchison Chris , Romanowski Charles , Barker Alexander , Jenkins Thomas
Published: July 2022

In the majority of cases of motor neuron disease (MND), diagnosis is clinical and unambiguous. However, given the gravity of the diagnosis, it is crucial that treatable mimics are differentiated accurately. We present three cases referred to our clinic with possible MND with unusual features that led to an alternative diagnosis. (1) A middle-aged man with swallowing, then speech problems and foot drop. Tongue movements were slow and electromyography (EMG) showed fibrillations/positive sharp waves. Following investigation, a tonsillar tumour involving the tongue root was identified, and the foot drop improved, suggesting unrelated common peroneal nerve palsy (related to weight loss) or lumbar radiculopathy. (2) An elderly man presenting with progressive unilateral leg weakness and localised fasciculations on EMG. Following investigation, a high-grade brain glioma was diagnosed. (3) An elderly woman presenting with progressive quadriparesis over 18 months with fibrillations and chronic denervation on EMG. Symmetrical weakness and short duration response to immunotherapy led to further serological investigation and a diagnosis of anti-GD1a motor neuropathy. She was treated successfully with intravenous immunoglobulin, cyclophosphamide and rituximab and is now in remission.

Published: July 2022

Most cardiac tumours are secondary to metastasis from extracardiac tumours. Obtaining biopsy from intracardiac lesions, especially from the left heart, is challenging, and the conventionally used methods are invasive and involve significant risks such as arrhythmias, tamponade, valvular damage and tumour embolisation. Endobronchial ultrasound (EBUS) is a minimally invasive procedure used to biopsy lymph nodes or mass lesions adjacent to the airways. Its safety and usefulness have been well established. Use of EBUS has expanded to several novel indications over the last few years. Here we report a case of a young woman with suspected metastatic disease to the heart, in whom traditional methods of biopsy had failed to give a diagnosis. EBUS-guided transbronchial intracardiac needle aspiration was safely performed from the left atrial mass lesion to obtain tissue for histopathological diagnosis. A diagnosis of metastatic adenocarcinoma with tumour embolisation to the heart was established.

Published: July 2022

A man in his 30s, with a history of two operated penetrating keratoplasty (PK), primarily for viral keratitis, presented with pain, redness and diminution of vision in his left eye of 4 days duration. Postoperatively, he was prescribed oral antivirals, topical steroid eyedrops, lubricants and antiglaucoma medications. Eight months after transplantation, an epithelial defect with heaped up margins was noted on anterior segment evaluation on a routine follow-up visit. On checking his medications, it was found that the patient was unknowingly using bromfenac drops in place of brimonidine tartrate for the past month. A diagnosis of neurotrophic keratitis was made in the setting of PK performed for viral keratitis, incited by use of topical bromfenac. The patient was prescribed preservative-free lubricants with immediate discontinuation of bromfenac drops. Topical steroid drops were withheld till the epithelial defect healed. Complete healing of the defect was noted after 4 weeks of therapy.

Limbic system symptoms of rabies infection
Authors: Mohindra Ritin , Madhav Mohata , Suri Vikas , Divyashree Krishna
Published: July 2022

Rabies is a fatal aggressive disease of the nervous system which predominantly causes motor and autonomic dysfunction. Limbic system involvement has been reported rarely, with limited data on its prevalence. The diagnosis becomes challenging when a patient presents with limbic system involvement in the absence of a clear history of an animal bite. We herein illustrate a case of a young man who presented with recurrent episodes of inappropriate ejaculation. He eventually developed hydrophobia and aerophobia, leading to a diagnosis of rabies. This case emphasises the importance of considering the possibility of rabies encephalitis when a patient presents with symptoms of limbic system involvement since early diagnosis helps in instituting appropriate public health measures and reducing exposure to infection. Furthermore, high-quality intensive care with supportive management is the mainstay of therapy in such patients until we have novel and effective antiviral drugs for rabies treatment.

Published: July 2022

A man in his late 50s, with uncontrolled type 2 diabetes mellitus (T2DM) and morbid obesity, presented to the hospital with complicated epididymo-orchitis. The onset of symptoms (scrotal pain, erythema and swelling) occurred after the use of empagliflozin, a sodium–glucose cotransporter 2 (SGLT2) inhibitor, for 2 months. His baseline antidiabetic medications were insulin, glipizide and metformin. Initially, he had failed treatment of epididymo-orchitis with oral levofloxacin for 3 weeks, followed by 2 weeks of doxycycline therapy. At the presentation to the hospital, an ultrasound of the scrotum revealed scrotal and right testicular abscess. The patient underwent right inguinal orchiectomy. Postoperatively, pus culture was positive forEnterococcus faecalisandCandida glabrata, and hence, he was treated with oral antibiotics including high-dose antifungal medications. Adequate wound care and regular follow-up demonstrated resolution of infection. This case highlights the risk of severe urogenital infection associated with the use of SGLT2 inhibitors in the setting of uncontrolled T2DM.

Published: July 2022

The COVID-19 pandemic has largely been made sense of as acrisis. However, usingcrisisas a temporal-analytical category arguably obscures the complexity of the different temporalities at work in the pandemic. In this article, we examine how the pandemic outbreak led to numerous acts of synchronisation and de-synchronisation—between humans and viruses, between social groups and even between historical ages. In order to make sense of the temporal consequences of an epidemic, we introduce the concept of ‘temporal technologies’, understood as a set of procedures that control, regulate, produce and assemble time in relational networks of both human and non-human actors. This article thus attempts to create a framework for understanding the epidemic experience in temporal terms by using ‘temporal technologies’ as an analytical tool.
Improving the Speed and Quality of Parallel Graph Coloring
Authors: Alabandi Ghadeer , Burtscher Martin
Published: July 2022

Graph coloring assigns a color to each vertex of a graph such that no two adjacent vertices get the same color. It is a key building block in many applications. In practice, solutions that require fewer distinct colors and that can be computed faster are typically preferred. Various coloring heuristics exist that provide different quality versus speed tradeoffs. The highest-quality heuristics tend to be slow. To improve performance, several parallel implementations have been proposed. This paper describes two improvements of the widely used LDF heuristic. First, we present a “shortcutting” approach to increase the parallelism by non-speculatively breaking data dependencies. Second, we present “color reduction” techniques to boost the solution of LDF. On 18 graphs from various domains, the shortcutting approach yields 2.5 times more parallelism in the mean, and the color-reduction techniques improve the result quality by up to 20%. Our deterministic CUDA implementation running on a Titan V is 2.9 times faster in the mean and uses as few or fewer colors as the best GPU codes from the literature.
A New Upper Bound on Cache Hit Probability for Non-Anticipative Caching Policies
Authors: Panigrahy Nitish K. , Nain Philippe , Neglia Giovanni , Towsley Don
Published: July 2022

Caching systems have long been crucial for improving the performance of a wide variety of network and web-based online applications. In such systems, end-to-end application performance heavily depends on the fraction of objects transferred from the cache, also known as the
cache hit probability
. Many caching policies have been proposed and implemented to improve the hit probability. In this work, we propose a new method to compute an upper bound on hit probability for all non-anticipative caching policies and for policies that have no knowledge of future requests. Our key insight is to order the objects according to the ratio of their

Hazard Rate

(HR)
function values to their sizes, and place in the cache the objects with the largest ratios till the cache capacity is exhausted. When object request processes are conditionally independent, we prove that this cache allocation based on the HR-to-size ratio rule guarantees the maximum achievable expected number of object hits across all non-anticipative caching policies. Further, the HR ordering rule serves as an upper bound on cache hit probability when object request processes follow either independent delayed renewal process or a Markov modulated Poisson process. We also derive closed form expressions for the upper bound under some specific object request arrival processes. We provide simulation results to validate its correctness and to compare it to the state-of-the-art upper bounds, such as produced by Bélády’s algorithm. We find it to be tighter than state-of-the-art upper bounds for some specific object request arrival processes such as independent renewal, Markov modulated, and shot noise processes.
A Generic Federated Recommendation Framework via Fake Marks and Secret Sharing
Authors: Lin Zhaohao , Pan Weike , Yang Qiang , Ming Zhong
Published: July 2022

With the implementation of privacy protection laws such as GDPR, it is increasingly difficult for organizations to legally collect users’ data. However, a typical machine learning-based recommendation algorithm requires the data to learn users’ preferences. Some recent works thus turn to develop federated learning-based recommendation algorithms, but most of them either cannot protect the users’ privacy well, or sacrifice the model accuracy. In this article, we propose a lossless and generic federated recommendation framework via fake marks and secret sharing (FMSS). Our FMSS can not only protect the two types of users’ privacy, i.e., rating values and rating behaviors, without sacrificing the recommendation performance, but can also be applied to most recommendation algorithms for rating prediction, item ranking, and sequential recommendation. Specifically, we extend existing fake items to fake marks, and combine it with secret sharing to perturb the data uploaded by the clients to a server. We then apply our FMSS to six representative recommendation algorithms, i.e., MF-MPC and NeuMF for rating prediction, eALS and VAE-CF for item ranking, and Fossil and GRU4Rec for sequential recommendation. The experimental results demonstrate that our FMSS is a lossless and generic framework, which is able to federate a series of different recommendation algorithms in a lossless and privacy-aware manner.

Published: July 2022

In this study, the daily lactation data of Holstein dairy cows in one lactation period (305 days) were used as lactation time series data. Empirical mode decomposition (EMD) was used to decompose milk yield series. The nonstationary milk yield series with multiple oscillation modes was decomposed into several components. After eliminating the interference components, the interference components were superimposed. Remaining component reconstruction was used to get the denoising milk yield series. The denoising milk yield series retained the basic characteristics of the original milk yield series and corrected the errors of the original data. The back propagation neural network (BPNN) was used to predict and compare the original milk yield series and the denoising milk yield series. The results showed that it was feasible to use EMD to smooth the original daily milk production data. The noise reduction milk production series was beneficial to the learning of prediction model and could improve the accuracy of prediction of daily milk production of dairy cows.

Background. Total knee arthroplasty (TKA) is often indicated for end-stage knee osteoarthritis management. The posterior-stabilized (PS) implant is one of the TKA implants with various component designs, including femoral component cutting jigs. However, little is known about how the differences in cutting jig designs affect the outcomes. This study aims to compare the radiographic and functional outcomes of the patients who underwent cemented TKA using all-in-one and four-in-one femoral component PS implants. Methods. A retrospective comparative study assessed patients who underwent cemented TKA using PS implants from 2018 to 2019. The patients were divided into all-in-one and four-in-one groups. Demographic data, surgery duration, postoperative radiological findings after one week, and functional outcomes after two years were collected and compared. Results. A total of 96 patients were included in the study, 55 patients were in all-in-one sample, and 41 patients were in four-in-one sample. The majority of the patients in both groups were female, aged >60 years old, overweight (BMI ≥ 25), and presented with an ASA score of II. We found significantly shorter surgery duration in the all-in-one group compared to the four-in-one group (128.00 ± 36.24 vs. 210.61 ± 57.54,

Based on the standards for wireless sensor system identification, the sensor node identity OID identification and the management object OID identification in the SNMP MIB are merged, and a management object OID identification coding mechanism for the SNMP‐based wireless sensor system is proposed to make the node management system only. The identity, attributes, and multiple entities of the target sensor node in the wireless sensor network can be identified and managed by the node management object OID. The source of abnormal medical big data generally uses two models of multidimensional data and sliding window for detection and verification. First, the sliding window can be used to detect abnormalities. The result is that under this condition, the detection rate of medical big data is more than 95%; the effect is very good, but in different dimensions, the detection rate of four‐dimensional data is 2.9% higher than that of a single‐dimensional one. On the basis of the ZigBee wireless network, the terminal signal transmission of fracture treatment can be realized. On this basis, combined with the actual needs of fracture treatment, it can be built with its wireless module. The wireless network has a certain basic function. The reform of the nursing system was carried out on the basis of the safety and reliability of the nursing system, the efficiency of the nursing system was improved, and timely and safe nursing services were achieved.

Authors: Shen Shuli
Published: July 2022

With the rapid development of the information technology, mining news content efficiently is a difficult problem faced by the government and enterprises. The classification, clustering, and prediction of neural network are used in news mining. A keyword based on neural network and word vector are proposed as a text feature model, and the model is compared with other neural network models. This paper studies the vectorization of text for similarity recommendation and introduces two models: word vector model and text vector model doc2vec based on neural network. In the model with word vector as feature vector, the recommendation accuracy is about 75.35%, doc2vec model is about 44.5%, and the recommendation accuracy of the model with keyword as text is about 88.61%. The recommendation accuracy is about 91%, and the performance has greatly improved. The more the number of keywords, the better the recommendation effect of the model. When the number is about 20, the improvement of the recommendation effect tends to be gentle, and the continuous increase of the number of keywords will increase the operation time of the model. It is proposed that the keyword and word vector based on neural network together as the text vector model can more accurately mine news data, quickly obtain news information, and make prediction and early warning for many industries such as the real estate industry.

Authors: Liu Long
Published: July 2022

In order to effectively detect and monitor athletes and record various motion data of targets, the study suggests a study of target tracking algorithms to detect the direction of motion video sports movement based on the neural network. A class of feedforward neural networks with convolutional computation and deep structure is one of the representative algorithms of deep learning. Firstly, the athlete image is obtained from the video frame; combined with the nonathlete image to construct the training set, use the bootstrapping algorithm to train the convolutional neural network classifier. In the case of input picture frames, pyramids of different scales are then constructed by subsampling, and the location of many candidate athletes is detected by a neural network of disruption. Finally, these centers calculate the center of gravity of the athletes, find the athlete to represent the candidate, and determine the location of the final athlete through a local search process. The results of the experiment show that the proposed scheme of 6000 frames in the two game videos is compared with the AdaBoost scheme, and the detection rate of the proposed scheme is 75.41% to calculate the average detection accuracy and false alarm speed of all players. The detection rate is higher than the AdaBoost scheme. Therefore, this scheme has a high detection rate and low false positives.
Provisional Decision-Making for Perioperative Blood Pressure Management: A Narrative Review
Authors: Song Qiliang , Li Jipeng , Jiang Zongming
Published: July 2022

Blood pressure (BP) is a basic determinant for organ blood flow supply. Insufficient blood supply will cause tissue hypoxia, provoke cellular oxidative stress, and to some extent lead to organ injury. Perioperative BP is labile and dynamic, and intraoperative hypotension is common. It is unclear whether there is a causal relationship between intraoperative hypotension and organ injury. However, hypotension surely compromises perfusion and causes harm to some extent. Because the harm threshold remains unknown, various guidelines for intraoperative BP management have been proposed. With the pending definitions from robust randomized trials, it is reasonable to consider observational analyses suggesting that mean arterial pressures below 65 mmHg sustained for more than 15 minutes are associated with myocardial and renal injury. Advances in machine learning and artificial intelligence may facilitate the management of hemodynamics globally, including fluid administration, rather than BP alone. The previous mounting studies concentrated on associations between BP targets and adverse complications, whereas few studies were concerned about how to treat and multiple factors for decision-making. Hence, in this narrative review, we discussed the way of BP measurement and current knowledge about baseline BP extracting for surgical patients, highlighted the decision-making process for BP management with a view to providing pragmatic guidance for BP treatment in the clinical settings, and evaluated the merits of an automated blood control system in predicting hypotension.

Authors: Qiu Wenjuan , Bai Fangfang
Published: July 2022

In order to investigate the influencing factors of AAD in the emergency ward and the clinical effect of probiotics, 100 AAD patients admitted to the emergency ward of our hospital from January 2021 to January 2022 and 100 healthy physical examination subjects are selected for conducting clinical trials. The subjects are, respectively, included in the AAD group and the healthy group. By using the random number table method, 100 patients in the AAD group are randomly divided into the probiotic group and traditional group, with 50 patients in each group. The traditional group receives conventional treatment, and the probiotic group is treated with Clostridium caseinate bifidobacterial probiotics additionally. Multivariate logistic analysis is performed on the risk factors for AAD, and the comparison of tumor necrosis factor‐α (TNF‐α), interleukin‐6 (IL‐6), and the intestinal microflora of the different groups before and after treatment is conducted. The experimental result reveals that probiotics treatment for AAD patients can reduce inflammatory response and promote intestinal colonization of beneficial bacteria such as bifidobacteria.
