Abstract
Objective: To investigate the effects of cerium oxide nanoenzyme-gelatin methacrylate anhydride (GelMA) hydrogel (hereinafter referred to as composite hydrogel) in the repair of infected full-thickness skin defect wounds in mice. Methods: This study was an experimental study. Cerium oxide nanoenzyme with a particle size of (116±9) nm was prepared by hydrothermal method, and GelMA hydrogel with porous network structure and good gelling performance was also prepared. The 25 μg/mL cerium oxide nanoenzyme which could significantly promote the proliferation of human skin fibroblasts and had high superoxide dismutase activity was screened out. It was added to GelMA hydrogel to prepare composite hydrogel. The percentage of cerium oxide nanoenzyme released from the composite hydrogel was calculated after immersing it in phosphate buffer solution (PBS) for 3 and 7 d. The red blood cell suspension of mice was divided into PBS group, Triton X-100 group, cerium oxide nanoenzyme group, GelMA hydrogel group, and composite hydrogel group, which were treated with corresponding solution. The hemolysis of red blood cells was detected by microplate reader after 1 h of treatment. The bacterial concentrations of methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli were determined after being cultured with PBS, cerium oxide nanoenzyme, GelMA hydrogel, and composite hydrogel for 2 h. The sample size in all above experiments was 3. Twenty-four 8-week-old male BALB/c mice were taken, and a full-thickness skin defect wound was prepared in the symmetrical position on the back and infected with MRSA. The mice were divided into control group without any drug intervention, and cerium oxide nanoenzyme group, GelMA hydrogel group, and composite hydrogel group applied with corresponding solution, with 6 mice in each group. The wound healing was observed on 3, 7, and 14 d after injury, and the remaining wound areas on 3 and 7 d after injury were measured (the sample size was 5). The concentration of MRSA in the wound exudation of mice on 3 d after injury was measured (the sample size was 3), and the blood flow perfusion in the wound of mice on 5 d after injury was observed using a laser speckle flow imaging system (the sample size was 6). On 14 d after injury, the wound tissue of mice was collected for hematoxylin-eosin staining to observe the newly formed epithelium and for Masson staining to observe the collagen situation (the sample size was both 3). Results: After immersion for 3 and 7 d, the release percentages of cerium oxide nanoenzyme in the composite hydrogel were about 39% and 75%, respectively. After 1 h of treatment, compared with that in Triton X-100 group, the hemolysis of red blood cells in PBS group, GelMA hydrogel group, cerium oxide nanoenzyme group, and composite hydrogel group was significantly decreased (P<0.05). Compared with that cultured with PBS, the concentrations of MRSA and Escherichia coli cultured with cerium oxide nanoenzyme, GelMA hydrogel, and composite hydrogel for 2 h were significantly decreased (P<0.05). The wounds of mice in the four groups were gradually healed from 3 to 14 d after injury, and the wounds of mice in composite hydrogel group were all healed on 14 d after injury. On 3 and 7 d after injury, the remaining wound areas of mice in composite hydrogel group were (29±3) and (13±5) mm2, respectively, which were significantly smaller than (56±12) and (46±10) mm2 in control group and (51±7) and (38±8) mm2 in cerium oxide nanoenzyme group (with P values all <0.05), but was similar to (41±5) and (24±9) mm2 in GelMA hydrogel group (with P values both >0.05). On 3 d after injury, the concentration of MRSA on the wound of mice in composite hydrogel group was significantly lower than that in control group, cerium oxide nanoenzyme group, and GelMA hydrogel group, respectively (with P values all <0.05). On 5 d after injury, the volume of blood perfusion in the wound of mice in composite hydrogel group was significantly higher than that in control group, cerium oxide nanoenzyme group, and GelMA hydrogel group, respectively (P<0.05). On 14 d after injury, the wound of mice in composite hydrogel group basically completed epithelization, and the epithelization was significantly better than that in the other three groups. Compared with that in the other three groups, the content of collagen in the wound of mice in composite hydrogel group was significantly increased, and the arrangement was also more orderly. Conclusions: The composite hydrogel has good biocompatibility and antibacterial effect in vivo and in vitro. It can continuously sustained release cerium oxide nanoenzyme, improve wound blood perfusion in the early stage, and promote wound re-epithelialization and collagen synthesis, therefore promoting the healing of infected full-thickness skin defect wounds in mice.

Abstract
The detection rate of multifocal / multicentric breast cancer (MMBC) is increasing, and the local treatment of MMBC is attracting more attention. Relevant research focuses on the selection of surgical methods, the application of radiotherapy, and the feasibility of local ablation. Currently, due to the high rate of local recurrence in breast conserving surgery, most Chinese doctors recommend mastectomy to patients with MMBC. Recent studies have shown that with the development of imaging technology, surgical techniques, accurate judgment of the resection margin, the emergence of new therapeutic drugs and the improvement of the accuracy of radiotherapy, for eligible patients with MMBC, breast conserving surgery did not increase the local recurrence rate while ensuring negative margin and cosmetic results. Whether patients with MMBC must receive adjuvant radiotherapy after mastectomy is controversial, with some evidence suggesting that MMBC may increase the risk of local recurrence and should be an important consideration for radiotherapy, and there is also evidence that the local recurrence rate of MMBC was higher regardless of the type of surgery. In general, the local treatment modality for MMBC is essentially the same as that for unifocal breast cancer, but more prospective studies are needed for further evaluation.

Abstract
Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.

Abstract
Enamel formation is a complex physiological process that depends on the coordinated regulation of multiple mechanisms. This process is quite sensitive to various local and systemic interference factors. Therefore, during the long period from the embryonic stage to adolescence or even adulthood, various interference factors may lead to enamel developmental defects. Among them, early life is the most sensitive stage to environmental factors exposure, while it is also the critical period of enamel development of deciduous and permanent teeth. Environmental factors exposure during this period often leads to varying degrees of enamel development defects. In this review, we generalize the research progress of environmental factors affecting enamel developmental defects, summarize the potential mechanisms of environmental factors leading to enamel developmental defects, and conclude the clinical management strategies based on tertiary prevention. This work hopes to provide a theoretical basis for preventing abnormal teeth development from the critical time window of early life, propose eugenics health consultation and promote children 's oral health management.

Abstract
As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Abstract
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been a major public health threat globally, especially during the beginning of the pandemic in 2020. Reverse transcription-quantitative PCR (RT-qPCR) is utilized for viral RNA detection as part of control measures to limit the spread of COVID-19. Collecting nasopharyngeal swabs for RT-qPCR is a routine diagnostic method for COVID-19 in clinical settings, but its large-scale implementation is hindered by a shortage of trained health professionals. Despite concerns over its sensitivity, saliva has been suggested as a practical alternative sampling approach to the nasopharyngeal swab for viral RNA detection. In this study, we spiked saliva from healthy donors with inactivated SARS-CoV-2 from an international standard to evaluate the effect of saliva on viral RNA detection. On average, the saliva increased the cycle threshold (CT) values of the SARS-CoV-2 RNA samples by 2.64 compared to the viral RNA in viral transport medium. Despite substantial variation among different donors in the effect of saliva on RNA quantification, the outcome of the RT-qPCR diagnosis was largely unaffected for viral RNA samples with CT values of <35 (1.55 log10 IU/mL). The saliva-treated viral RNA remained stable for up to 6 h at room temperature and 24 h at 4°C. Further supplementing protease and RNase inhibitors improved the detection of viral RNA in the saliva samples. Our data provide practical information on the storage conditions of saliva samples and suggest optimized sampling procedures for SARS-CoV-2 diagnosis. IMPORTANCE The primary method for detection of SARS-CoV-2 is using nasopharyngeal swabs, but a shortage of trained health professionals has hindered its large-scale implementation. Saliva-based nucleic acid detection is a widely adopted alternative, due to its convenience and minimally invasive nature, but the detection limit and direct impact of saliva on viral RNA remain poorly understood. To address this gap in knowledge, we used a WHO international standard to evaluate the effect of saliva on SARS-CoV-2 RNA detection. We describe the detection profile of saliva-treated SARS-CoV-2 samples under different storage temperatures and incubation periods. We also found that adding protease and RNase inhibitors could improve viral RNA detection in saliva. Our research provides practical recommendations for the optimal storage conditions and sampling procedures for saliva-based testing, which can improve the efficiency of COVID-19 testing and enhance public health responses to the pandemic.

Abstract
Objective: To evaluate HPV prevalence and type distribution in Chinese juvenile-onset recurrent respiratory papillomatosis (JoRRP) patients. Methods: We searched China National Knowledge Infrastructure, Wanfang data, China Biology Medicine disc, PubMed, Embase, and the Cochrane Library for studies assessing HPV infection of Chinese JoRRP patients up to 1 October, 2022. Two authors independently performed literature selection, data extraction, and quality assessment. HPV prevalence and HPV type-specific prevalence were pooled using a random effects model after Freeman-Tukey double arcsine transformation. All analyses were performed with R 4.1.3 software. Results: Nineteen publications investigating HPV infection of JoRRP patients were included in the final analyses. Of these, 16 studies reported HPV prevalence with a sample size of 1 528 patients, and 11 studies reported HPV6 prevalence and HPV11 prevalence with a sample size of 611 patients. All studies were graded as medium quality. In Chinese JoRRP patients, the synthesized HPV prevalence was 92.0% (95%CI:86.0%-96.6%, I2=87%), HPV6 prevalence was 42.4% (95%CI:34.9%-50.1%, I2=61%), and HPV11 prevalence was 72.3% (95%CI:59.0%-83.9%, I2=87%). All the pooled prevalence persisted in subgroup analyses stratified by publication year, sample size, and specimen type (P>0.05). There was no evidence of publication bias. In Chinese JoRRP patients, HPV16, 18, 31, 33, 52, and 58 prevalence was very low. Conclusions: Our findings suggested high HPV prevalence in Chinese JoRRP patients, and the most common HPV types were HPV6 and HPV11.

Abstract
Enamel formation is a series of complex physiological processes, which are regulated by critical genes spatially and temporally. These processes involve multiple developmental stages covering ages and are prone to suffer signal interference or gene mutations, ultimately leading to developmental defects of enamel (DDE). Epigenetic modifications have important regulatory roles in gene expression during enarnel development. New technologies including high-throughput sequencing, chromatin immunoprecipitation sequencing (ChIP-seq), and DNA methylation chip are emerging in recent years, making it possible to establish genome-wide epigenetic modification profiles during developmental processes. The regulatory role of epigenetic modification with spatio-temporal pattern, such as DNA methylation, histone modification and non-coding RNA, has significantly expanded our understanding of the regulatory network of enamel formation, providing a new theoretical basis of clinical management and intervention strategy for DDE. The present review briefly describes the enamel formation process of human beings' teeth as well as rodent incisors and summarizes the dynamic characteristics of epigenetic modification during enamel formation. The functions of epigenetic modification in enamel formation and DDE are also emphatically discussed.

Abstract
The ^{13}C(α,n)^{16}O reaction is the main neutron source for the slow-neutron-capture process in asymptotic giant branch stars and for the intermediate process. Direct measurements at astrophysical energies in above-ground laboratories are hindered by the extremely small cross sections and vast cosmic-ray-induced background. We performed the first consistent direct measurement in the range of E_{c.m.}=0.24 to 1.9 MeV using the accelerators at the China Jinping Underground Laboratory and Sichuan University. Our measurement covers almost the entire intermediate process Gamow window in which the large uncertainty of the previous experiments has been reduced from 60% down to 15%, eliminates the large systematic uncertainty in the extrapolation arising from the inconsistency of existing datasets, and provides a more reliable reaction rate for the studies of the slow-neutron-capture and intermediate processes along with the first direct determination of the alpha strength for the near-threshold state.

Abstract
The Omicron severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant led to a dramatic global epidemic wave following detection in South Africa in November 2021. The BA.1 Omicron lineage was dominant and responsible for most SARS-CoV-2 outbreaks in countries around the world during December 2021-January 2022, while other Omicron lineages, including BA.2, accounted for the minority of global isolates. Here, we describe the Omicron wave in the Philippines by analysing genomic data. Our results identify the presence of both BA.1 and BA.2 lineages in the Philippines in December 2021, before cases surged in January 2022. We infer that only the BA.2 lineage underwent sustained transmission in the country, with an estimated emergence around 18 November 2021 (95 per cent highest posterior density: 6-28 November), while despite multiple introductions, BA.1 transmission remained limited. These results suggest that the Philippines was one of the earliest areas affected by BA.2 and reiterate the importance of whole genome sequencing for monitoring outbreaks.

Abstract
Objective: To evaluate the safety and immunogenicity of hepatitis E vaccine(HEV)in Maintenance hemodialysis(MHD)patients. Methods: Based on an open-labeled controlled trial, from May 2016 to March 2018, 35 eligible MHD patients were recruited in the Hemodialysis Center of Zhongshan Hospital Affiliated to Xiamen University as the experimental group, and 70 MHD patients with matched age, gender and underlying diseases as the control group. The experimental group received HEV at 0, 1 and 6 months according to the standard vaccination procedures, while the control group received routine diagnosis and treatment without vaccine and placebo injection to observe the safety and immunogenicity of the vaccine. The safety of vaccine in MHD population was evaluated by the incidence of adverse reactions/events in the experimental and control groups. The immunogenicity of HEV in MHD patients was evaluated by comparing the data from the phase Ⅲ clinical trial. Results: The overall incidence of adverse reactions/events was 17.1% (18/105), and there were no grade 3-4 adverse reactions/events related to vaccination. In the experimental group, the incidence of local adverse reactions/events was 20.0% (7/35), and the incidence of systemic adverse reactions/events was 17.1% (6/35).There was no significant difference in the incidence of systemic adverse reactions/events between the experimental group and the control group (P>0.05). There were 23 patients receiving 3 doses with the standard schedule. The positive rate of HEV-IgG antibody was 100% and the GMC was 14.47(95%CI:13.14-15.80) WU/ml, which showed no significant difference compared with the 46 patients in Phase Ⅲ clinical trial (t=-1.04, P>0.05). Conclusion: Recombinant HEV has good safety and immunogenicity in MHD patients.

Abstract
Objective: To explore the effect of lead exposure on the neurobehavior and gut microbiota community structure in mice. Methods: In August 2019, 64 C57BL/6 mice were randomly divided into 4 groups: control group (0 ppm) , low lead exposure group (20 mg/l) , medium lead exposure group (100 mg/l) and high lead exposure group (500 mg/l) . During the experiment, they were free to eat and drink. The drinking water of the lead exposure group was mixed with lead acetate, and sodium acetate was added in the control group. After 10 weeks of exposure, the Morris water maze was used to test the learning and memory ability of each group of mice, and then they were sacrificed for sampling. ICP-MS was used to detect lead content in whole blood and brain tissue. ELISA was used to determine the level of IL-1β in mouse serum. 16S rRNA sequencing was used to detect the structural diversity of the intestinal flora in feces, and then the correlation between the flora and behavior indicators was analyzed. Results: In the Morris water maze experiment, compared with the control group, there was no significant difference in the body weight and swimming speed of the mice in the lead exposure groups. The escape latency of the mice in the 100 mg/l and 500 mg/l dose groups was prolonged, and the number of platform crossings decreased (P<0.05) ; meanwhile, the staying time of the mice in the 500 mg/l Pb-treated group in the target quadrant was lower than that of the control group, and the difference was statistically significant (P<0.05) . Compared with the control group, the blood lead content of the mice in each lead exposure group was significantly increased, and the brain lead content of mice in the 500 mg/l dose group was significantly elevated (P<0.05) . The serum IL-1β levels of mice in each lead exposure group were higher than those of the control group (P<0.05) . At the phylum level, the relative abundance of the Proteobacteria phylum in all of Pb-treated groups was significantly increased (P<0.05) ; at the genus level, Allobaculum, Desulfovibrio, Lachnospiraceae_NK4A136_group, Turicibacter and Ureaplasma were significantly increased (P<0.05) . Among them. The relative abundance of Desuffaoibrio, Turici bacter, and Ureaplasma was negatively correlated with the residence time of mice in the quadrant of the platform (r=-0.32, -0.29, -0.44, P<0.05) . Conclusion: Lead exposure induced learning and memory impairments in mice, which may be related to the disturbance of the gut microbiota.

Abstract
Biological mineralization is a natural process manifested by living organisms in which inorganic minerals crystallize under the scrupulous control of biomolecules, producing hierarchical organic-inorganic composite structures with physical properties and design that galvanize even the most ardent structural engineer and architect. Understanding the mechanisms that control the formation of biominerals is challenging in the biomimetic engineering of hard tissues. In this regard, the contribution of cryogenic electron microscopy (cryo-EM) has been nothing short of phenomenal. By preserving materials in their native hydrated status and reducing damage caused by ion beam radiation, cryo-EM outperforms conventional transmission electron microscopy in its ability to directly observe the morphologic evolution of mineral precursor phases at different stages of biomineralization with nanoscale spatial resolution and subsecond temporal resolution in 2 or 3 dimensions. In the present review, the development and applications of cryo-EM are discussed to support the use of this powerful technique in dental research. Because of the rapid development of cryogenic sample preparation techniques, direct electron detection, and image-processing algorithms, the last decade has witnessed an exponential increase in the use of cryo-EM in structural biology and materials research. By amalgamating with other analytic techniques, cryo-EM may be used for qualitative and quantitative analyses of the kinetics and thermodynamic mechanisms in which organic macromolecules participate in the transformation of mineral precursors from their original liquid state to amorphous and ultimately crystalline phases. The present review concentrates on the biomineralization of calcium phosphate mineral phases, while that of calcium carbonate, silica, and magnetite is only briefly mentioned. Bioinspired organic matrix-mediated inorganic crystallization strategies are discussed from the perspective of tissue regeneration engineering.

Abstract
Atherosclerotic cardiovascular disease (ASCVD), a series of cardiovascular diseases based on atherosclerosis, has attracted more clinical attention. However, with the increase of population-based research results, the diagnostic value of traditional blood lipid parameters such as low density lipoprotein-cholesterol (LDL-C) is showing limitations. In recent years, a large number of studies have confirmed that small dense low-density lipoprotein cholesterol (sdLDL-C) has lower affinity with low-density lipoprotein receptor, longer circulation time and easier to penetrate arterial endothelium, so it has stronger atherogenic effect. Therefore, we summarize the common detection methods of sdLDL-C, the research progress of the correlation between sdLDL-C and ASCVD risk, as well as the intervention measures and influencing factors of sdLDL-C level, in order to deepen the clinician's understanding of the role of sdLDL-C in ASCVD and achieve the early prevention, early detection and early diagnosis of chronic atherosclerosis.

Abstract
Gastric varices are one of the serious complications of liver cirrhotic portal hypertension. Balloon-occluded retrograde transvenous obliteration (BRTO), as an interventional treatment method, can effectively prevent and control gastroesophagel variceal bleeding. Simultaneously, it has an obvious effect in the treatment of hepatic encephalopathy and liver function improvement. This article reviews the clinical application and research progress of BRTO at home and abroad in recent years, with a view to provide reference for clinical treatment.

Abstract
We studied the mechanisms by which microRNA-126 regulates proliferation and migration of human umbilical vein endothelial cells (HUVEC) cultured in a medium with high glucose concentration and treated with chemokine CXCL8. Cell proliferation, apoptosis, and migration were analyzed by the CCK-8 assay, Annexin V-PI staining, and Transwell assay, respectively. The ratios of p-ERK/ERK, p-P38/P38, p-JNK/JNK were determined by ELISA. HUVEC cells cultured in the presence of high glucose concentration (30 mmol/ml) and treated with CXCL8 (50 ng/ml) demonstrated more intensive proliferation, migration, and p-ERK/ERK, p-P38/P38, and p-JNK/JNK ratios and significantly lower apoptosis rate than control cells (high glucose, no treatment) and cells treated with CXCL8 and transfected with microRNA-126-mimic. Thus, microRNA-126 regulates proliferation and migration of HUVEC cells cultured in the presence of high glucose concentrations and treated with CXCL8 through inhibition of MAPK signaling pathway.

Abstract
Wild birds are considered the natural reservoir of influenza A viruses (IAVs) making them critical for IAV surveillance efforts. While sea ducks have played a role in novel IAV emergence events that threatened food security and public health, very few surveillance samples have been collected from sea duck hosts. From 2014–2018, we conducted surveillance focused in the Mississippi flyway, USA at locations where sea duck harvest has been relatively successful compared to our other sampling locations. Our surveillance yielded 1662 samples from sea ducks, from which we recovered 77 IAV isolates. Our analyses identified persistence of sea duck specific IAV lineages across multiple years. We also recovered sea duck origin IAVs containing an H4 gene highly divergent from the majority of North American H4-HA with clade node age of over 65 years. Identification of IAVs with long branch lengths is indicative of substantial genomic change consistent with persistence without detection by surveillance efforts. Sea ducks play a role in the movement and long-term persistence of IAVs and are likely harboring more undetected IAV diversity. Sea ducks should be a point of emphasis for future North American wild bird IAV surveillance efforts.

Objective: To explore the effects of direct antiviral agent (DAAs) on the frequency of peripheral blood mononuclear cells and their activating factors sCD14s and CD163 in patients with chronic hepatitis C. Methods: Data of 15 treatment-naive chronic hepatitis C patients and 10 healthy controls were collected. Patients with chronic hepatitis C were treated with DAAs for 12 weeks. Blood samples were collected at 0, 4 and 12 weeks respectively, and blood samples of healthy controls were used as controls. Flow cytometry was used to detect the frequency of classical CD14(++)CD16(-) mononuclear cells and pro-inflammatory CD14(+)CD16(+) mononuclear cells in peripheral blood. Serum sCD14s and sCD163 were detected by enzyme-linked immunosorbent assay. The comparison between the two groups was performed by t-test. The comparison between multiple groups was performed by analysis of variance, and further pairwise comparison was performed by LSD-t test. Results: Prior DAAs treatment, peripheral blood CD14(+)CD16(+) mononuclear cell frequency (18.49% ± 1.54% vs. 10.65% ± 0.83%), serum sCD14s [(64 407.38 ± 5778.49) pg/ml vs. (28 370.76 ± 2 357.68 ) pg/ml] and sCD163 [(22 853.80 ± 4 137.61) pg/ml vs. (2 934.41 ± 223.31) pg/ml] were all higher than healthy controls (P < 0.05), while the frequency of CD14(++)CD16(-) mononuclear cells in peripheral blood was lower than healthy controls (59.14%±0.54% vs. 72.75%±1.31%, P < 0.01). During DAAs treatment, CD14(+)CD16(+) mononuclear cells frequency, serum sCD14 and sCD163 were all decreased significantly. After 12 weeks of treatment, CD14(+)CD16(+) mononuclear cells had decreased to nearly normal level (12.42% ± 1.60% vs. 10.65% ± 0.83%, P > 0.05), and serum sCD14 and scd163 were still higher than those of healthy controls [sCD14: (44 390.06 ± 3 330.17) pg / ml vs. (28 370.76 ± 2 357.68) pg/ml, Scd163: (11 494.79 ± 1 836.97) pg / ml vs. (2 934.41 ± 223.31) pg / ml, P < 0.01], while the frequency of CD14(++)CD16(-)mononuclear cells had gradually increased during the course of treatment and neared healthy control level after 12 weeks of treatment. There was no statistically significant difference between the two groups (71.54) % ± 2.99% vs. 72.75% ± 1.31%, P > 0.05). Conclusion: DAAs therapy can reduce the activation of peripheral blood mononuclear cells in patients with chronic hepatitis C.

Abstract
OBJECTIVE To investigate the prevalence and risk factors of Blastocystis infections among primary school students in Jiangjin District, Chongqing City. METHODS A cross-sectional questionnaire survey was conducted among students sampled from a primary school in Jiangjin District, Chongqing City on April, 2018, and their stool samples were collected for microscopic examinations, in vitro culture and PCR assays to analyze the prevalence of Blastocystis infections and subtype of the parasite. In addition, the risk factors of Blastocystis infections among primary school students were identified using univariate analysis and multivariate logistic regression analysis. RESULTS A total of 466 primary students were surveyed, and the subjects had a mean age of (9.81±1.66) years and included 236 males (50.64%) and 230 females (49.36%). The prevalence of Blastocystis infections was 15.24% (71/466) among the study students, and there was no significance difference in the prevalence between male and fe- male students (16.52% vs. 13.91%; χ2 = 0.616, P = 0.433). In addition, there was a significant difference in the prevalence of Blastocystis infections among grade 1 (6.35%, 4/63), grade 2 (5.17%, 3/58), grade 3 (21.74%, 15/69), grade 4 (25.30%, 21/83), grade 5 (10.19%, 11/108) and grade 6 students (20.00%, 17/85) (χ2 = 15.410, P = 0.009). There were four Blastocystis subtypes characterized (ST1, ST3, ST6 and ST7), in which ST6 was the most common subtype (45.07%, 32/71), followed by ST3 (25.35%, 18/71). Multivariate logistic regression analysis revealed that minority ethnicity [odds ratio (OR) = 4.259, 95% confidential inter- val (CI) : (1.161, 15.621)] and low maternal education level (primary school and below) [OR = 9.038, 95% CI: (1.125, 72.642)] were identified as risk factors of Blastocystis infection among primary school students in Jiangjin District, Chongqing City. CONCLUSIONS There is a high prevalence of Blastocystis infections detected among primary school students in Jiangjin District, Chongqing City, and ST6 and ST3 are predominant subtypes. Minority ethnicity and low maternal education level (primary school and below) are risk factors for Blastocystis infections in primary school students.

Abstract
Emergence and intercontinental spread of highly pathogenic avian influenza A (HPAI) H5Nx virus clade 2.3.4.4 has resulted in substantial economic losses to the poultry industry in Asia, Europe, and North America. The long-distance migratory birds have been suggested to play a major role in the global spread of avian influenza viruses during this wave of panzootic outbreaks since 2013. Poultry farm epidemics caused by multiple introduction of different HPAI novel subtypes of clade 2.3.4.4 viruses also occurred in Taiwan between 2015 and 2017. The mandatory and active surveillance detected H5N3 and H5N6 circulation in 2015 and 2017, respectively, while H5N2 and H5N8 were persistently identified in poultry farms since their first arrival in 2015. This study intended to assess the importance of various ecological factors contributed to the persistence of HPAI during three consecutive years. We used satellite technology to identify the location of waterfowl flocks. Four risk factors consistently showed strong association with the spatial clustering of H5N2 and H5N8 circulations during 2015 and 2017, including high poultry farm density (aOR:17.46, 95%CI: 5.91–74.86 and 8.23, 95% CI: 2.12–54.86 in 2015 and 2017, respectively), poultry heterogeneity index (aOR of 12.28, 95%CI: 5.02–31.14 and 2.79, 95%CI: 1.00–7.69, in 2015 and 2017, respectively), non-registered waterfowl flock density (aOR: 6.8, 95%CI: 3.41–14.46 and 9.17, 95%CI: 3.73–26.20, in 2015 and 2017, respectively) and higher percentage of cropping land coverage (aOR of 1.36, 95%CI: 1.10–1.69 and 1.04, 95%CI: 1.02–1.07, in 2015 and 2017, respectively). Our study highlights the application of remote sensing and clustering analysis for the identification and characterization of environmental factors in facilitating and contributing to the persistent circulation of certain subtypes of H5Nx in poultry farms in Taiwan.

Abstract
The continual emergence of novel influenza A strains from non-human hosts requires constant vigilance and the need for ongoing research to identify strains that may pose a human public health risk. Since 1999, canine H3 influenza A viruses (CIVs) have caused many thousands or millions of respiratory infections in dogs in the United States. While no human infections with CIVs have been reported to date, these viruses could pose a zoonotic risk. In these studies, the National Institutes of Allergy and Infectious Diseases (NIAID) Centers of Excellence for Influenza Research and Surveillance (CEIRS) network collaboratively demonstrated that CIVs replicated in some primary human cells and transmitted effectively in mammalian models. While people born after 1970 had little or no pre-existing humoral immunity against CIVs, the viruses were sensitive to existing antivirals and we identified a panel of H3 cross-reactive human monoclonal antibodies (hmAbs) that could have prophylactic and/or therapeutic value. Our data predict these CIVs posed a low risk to humans. Importantly, we showed that the CEIRS network could work together to provide basic research information important for characterizing emerging influenza viruses, although there were valuable lessons learned.

Abstract
Highly pathogenic avian influenza (HPAI) A(H5) viruses belonging to clade 2.3.4.4c of the A/goose/Guangdong/1/96-like (Gs/GD) lineage caused severe global outbreaks in domestic birds from 2014 to 2015, that also represented the first incursions of Gs/GD viruses into Taiwan and the USA. However, few studies have investigated the circulation of clade 2.3.4.4c viruses after 2015. Here, we describe Gs/GD clade 2.3.4.4c and Mexican-like H5N2 viruses that were isolated in Taiwan during active surveillance conducted in chicken farms from February to March 2019. Phylogenetic analysis demonstrated two distinct genome constellations of the clade 2.3.4.4c H5 viruses, with the internal genes of one of the new genotypes closely related to a virus isolated from a pintail (Anas acuta) in Taiwan, providing the first direct evidence that migratory birds play a role in importing viruses into Taiwan. Our study also confirmed the co-circulation of Gs/GD clade 2.3.4.4c and Mexican-like H5 lineage viruses in Taiwan, presenting a rare case where Gs/GD viruses developed sustained transmission alongside another enzootic H5 lineage, raising the possibility that homosubtypic immunity may mask virus transmission, potentially frustrating detection, and the implementation of appropriate control measures. To eradicate H5 viruses from poultry in Taiwan, further studies on the effect of co-circulation in poultry of low pathogenic avian influenza and HPAI viruses are needed. Furthermore, only with continued surveillance efforts globally can we fully discern dispersal patterns and risk factors of virus transmission both to and within Taiwan.

Abstract
BACKGROUND Human infections with avian influenza viruses (AIV) represent a persistent public health threat. The principal risk factor governing human infection with AIV is from direct contact with infected poultry and is primarily observed in Asia and Egypt where live-bird markets are common. AREAS OF AGREEMENT Changing patterns of virus transmission and a lack of obvious disease manifestations in avian species hampers early detection and efficient control of potentially zoonotic AIV. AREAS OF CONTROVERSY Despite extensive studies on biological and environmental risk factors, the exact conditions required for cross-species transmission from avian species to humans remain largely unknown. GROWING POINTS The development of a universal ('across-subtype') influenza vaccine and effective antiviral therapeutics are a priority. AREAS TIMELY FOR DEVELOPING RESEARCH Sustained virus surveillance and collection of ecological and physiological parameters from birds in different environments is required to better understand influenza virus ecology and identify risk factors for human infection.

Abstract
Infectious bronchitis virus (IBV) causes respiratory diseases in chickens and poses an economic threat to the poultry industry worldwide. Despite vaccine use, there have been field outbreaks of IBV in Taiwan. This study aimed to characterize the emerging IBV variants circulating in Taiwan. The analysis of the structural protein genes showed that these variants emerged through frequent recombination events among Taiwan strains, China strains, Japan strains and vaccine strains. Cross‐neutralization tests revealed that two of the variants exhibited novel serotypes. Clinicopathological assessment showed that two of the variants caused high fatality rates of 67% and 20% in one‐day‐old SPF chicks, and all the variants possessed multiorgan tropisms, including trachea, proventriculus and urogenital tissues. Furthermore, the commercial live‐attenuated Mass‐type vaccine conferred poor protection against these variants. This study identified novel genotypes, serotypes and pathotypes of emerging IBV variants circulating in Taiwan. There is an urgent need for effective countermeasures against these variant strains.

Abstract
OBJECTIVE To understand the prevalence and risk factors of Blastocystis hominis infection in inpatients in Jiangjin District, Chongqing City. METHODS A cross-sectional study was conducted in a community hospital in Jiangjin District, Chongqing City, and the inpatients were surveyed by questionnaires. After obtaining the informed consent from the inpatients or legal guardians, the stool and blood samples were collected and examined by microscopy and PCR from April 17 to May 1, 2018. The univariate analysis and logistic regression analysis were used to analyze the risk factors of the B. hominis infection. RESULTS A total of 198 hospitalized patients were investigated, and the infection rate of B. hominis was 10.61% (21/198), and the infection rate of the females (12.10%) was higher than that of the males (8.11%), but the difference was not statistically significant. The highest rate of infection was 19.23% in the age group of 10 to 20 years, followed by 17.74% in the age group of 60 years and above, and the lowest rate was 2.38% in the age group of 20 to 40 years. The difference in infection rates of B. hominis among the different age groups was statistically significant (P < 0.05). The infection rate of B. hominis in the people who used dry pail latrines was 33.30%, which was higher than that of the people who used water flush toilets (9.10%) (P < 0.05). The genotypes of B. hominis were ST1, ST3, ST6 and ST7, and ST6 and ST3 being the most predominant genotypes which accounted for 47.62% (10/21) and 38.10% (8/21) respectively, and among the infected males, the genotypes were only ST3 and ST6. The multiple logistic regression analysis showed that among the factors affecting B. hominis infection, only keeping pets was a risk factor [OR = 3.798, 95% CI (1.245, 11.581), P < 0.05]. CONCLUSIONS A high prevalence of B. hominis infection is found in the inpatients in Jiangjin District, Chongqing City, the predominant genotypes are ST6 and ST3, and keeping pets may be one of the main risk factors.

Abstract
Objective: To investigate the regulation of curculigoside on osteogenic differentiation of MG63 and the protective effect on osteoporosis model mice. Methods: The effects of curculigoside on the survival rate of dexamethasone or H(2)O(2) treated MG63 were detected by methyl thiazolyl tetrazolium (MTT). The specimens were divided into six groups: blank control group, blank administration group, model group (dexamethasone or H(2)O(2) treatment group), low dose group (dexamethasone or H(2)O(2)+1.0 μmol/L curculigoside), medium dose group (dexamethasone or H(2)O(2)+2.5 μmol/L curculigoside) and high dose group (dexamethasone or H(2)O(2)+5.0 μmol/L curculigoside), the sample size of each group was 10. Western blotting was used to detect the expression of osteogenic differentiation-related proteins [type Ⅰ collagen, integrin β1, osteoblast-specific transcription factor (Osterix), osteocalcin and osteopontin] in MG63 cells after 1, 7 and 14 days incubated with 0, 1.0, 2.5 and 5.0 μmol/L of curculigoside. The sample size for each group at each time point was six. The experimental mice were divided into 4 groups: blank group, model group (dexamethasone treatment group), curculigoside low-dose group (dexamethasone+5 mg/kg curculigoside) and high-dose group (dexamethasone+45 mg/kg curculigoside), twenty each. After treatment, the tibia of the mice in each group were subjected to sacral HE staining. The number of osteoclasts was counted, and the levels of oxidative related factors in serum were determined by enzyme-linked immunosorbent assay (ELISA). Results: The MTT results showed that compared with the blank control group [(100±3.7)%], the cell survival rate decreased to (44.1±5.7)% after treatment with dexamethasone, and the survival rate increased to (79.7±3.8)% after treatment with 5.0 μmol/L of curculigoside. The cell survival rate decreased to (59.1±4.7)% after H(2)O(2) treatment, and the survival rate increased to (80.8±3.5)% after treatment with 2.5 μmol/L of curculigoside. The results of Western blotting showed that the expression of type Ⅰ collagen and integrin β1 in MG63 cells was significantly increased after 1.0, 2.5 and 5.0 μmol/L of curculigoside for 1, 7 and 14 days compared with 0 μmol/L of curculigo side for the same period. After increasing (P<0.05), the expression of Osterix and osteocalcin was significantly increased after 1 day of incubation (P<0.05). However, compared with 0 μmol/L curculigoside treatment, the expression of osteopontin in MG63 cells was not significantly different after incubation with 1.0, 2.5, 5.0 μmol/L of curculigoside for 7 and 14 days (P>0.05). Compared with the blank group, the number of tibia osteoclasts in the osteoporosis model group increased. In the low-dose and high-dose groups of curculigoside, the tibia cortex was more continuous and the number of osteoclasts decreased. Compared with the blank group, the activity of oxygen in the osteoporosis model group was significantly increased (P<0.05), and superoxide dimutase and catalase were significantly decreased (P<0.05). Conclusions: Curculigoside promotes the differentiation of MG63 cells by increasing the expression of osteoblast differentiation-related proteins, and has a certain therapeutic effect on dexamethasone-induced osteoporosis mice.

Abstract
Objective: To evaluate the influence of Barrett calculator and AcrySof calculator on astigmatism correction effect. Methods: This is a randomized prospective study. A total of 64 cases (81 eyes) who planed to undergo phacoemulsification at Tianjin Medical University Eye Hospital during January 2017 and March 2018 were enrolled and divided into two groups randomly, including of the Barrett calculator group of 34 cases (41 eyes) and the AcrySof calculator group of 30 cases (40 eyes). Preoperative ocular biological parameters were measured using Lenstar LS900. The Toric intraocular lenses (IOL) plans were determined based on Barrett calculator and the AcrySof calculator for the two groups respectively. Subjective optometry was performed by phoropter and Toric IOL alignment was detected by slitlamp examination at 1 and 3 months postoperatively. Statistical analysis was taken with the data of 29 cases (35 eyes) in the Barrett calculator group and 26 cases (35 eyes) in the AcrySof calculator group, there were 20 males (25 eyes) and 35 females (45 eyes) with an average age of (72±10) years. The difference between the predicted residual astigmatism by the two calculators and the residual astigmatism obtained by postoperative optometry is the error of refractive astigmatism (ERA). The magnitude error is the algebraic difference of ERA. Vector error(VE) is a vector difference of ERA. Statistical analysis of magnitude error and VE between the two groups were taken by student's t test or rank sum test. Results: At 1 months and 3 months, the magnitude error absolute value of Barrett calculator group were (0.19±0.16)D, (0.28±0.24)D, and those of AcrySof calculator group were (0.36±0.28)D, (0.46±0.41)D, and the differences were statistically significant (t=-3.050, -2.036, both P<0.05). At 1 month postoperatively, the overall, with-the-rule astigmatism, and against-the-rule astigmatism VE of the Barrett calculator group were (0.30±0.21)D, (0.26±0.22)D, (0.37±0.26)D respectively, and those of the AcrySof calculator group were (0.47±0.33)D, (0.51±0.34)D and (0.52±0.38)D respectively, the differences between the two groups were statistically significant (t=-2.533, -2.436, -2.150, all P<0.05). At 3 months postoperatively, the overall, with-the-rule astigmatism, and against-the-rule astigmatism VE of the Barrett calculator group were (0.37±0.28)D, (0.29±0.17)D, (0.35±0.27)D respectively, and those of the AcrySof calculator group were (0.59±0.46)D, (0.54±0.37)D, (0.64±0.52)D respectively, the differences between the two groups were statistically significant (t=-2.142, -2.038, -2.481, all P<0.05).The difference of X(EV) between the Barrett calculator group and the AcrySof calculator group was statistically significant[-0.13(-0.36-0.80)D vs. 0.19(-1.01-0.71)D, Z=-2.965,P<0.01], and the difference of Y(EV) was statistically significant [-0.02(-0.51-0.64)D vs. -0.15(-0.88-1.10)D, Z=-2.076, P<0.05] at 1 months. There was no significant difference in X(EV) and Y(EV) (both P>0.05) at 3 months. Conelusion: As compared to AcrySof Toric calculator, the application of Barrett calculator in selecting Toric IOL may reduce ERA and improve Toric IOL correction outcomes.

Abstract
BACKGROUND Glioma is a type of tumor that occurs in the brain and accounts for almost 30 % of all brain and central nervous system tumors and 80 % of all malignant brain tumors. In this study, we investigate the role of cAMP response element-binding protein (CREB) in the progression of glioma. METHODS Tissue samples from glioma patients were collected and examined for expression of CREB and its correlation with tumor grades. CREB was then knocked down via siRNA to see if reduced expression of CREB affects cell proliferation and migration. Factors involved in cell cycles, adhesion and apoptosis were examined as well. Moreover, CRESP/CAS9 mediated knockout of CREB was conducted and athymic Nude mice model was used to investigate CREB's role in vivo. RESULTS The evaluated expression level of CREB in glioma patients was correlated with tumor grades. Knockdown of CREB via siRNA in glioma cell line U251 significantly inhibited the proliferation and migration of tumor cells. Moreover, CyclinD1 and Bcl-2 expression were reduced, as well as phosphorylation of IRK1/2 and AKT. Additionally, knockout of CREB via CRESP/CAS9 inhibited tumor formation of U251 cells in athymic Nude mice model. CONCLUSIONS In conclusion, our data suggest that over expression of CREB may contribute to progression of glioma and knockdown of CREB expression may serve as a novel target for therapy (Tab. 1, Fig. 6, Ref. 25).

Abstract
Background & aims: Biopsy is the gold standard for staging liver fibrosis, but it may be accompanied by complications. As an alternative, non-invasive markers such as transient elastography (for liver fibrosis) and certain combinations of routine blood markers (liver function tests, full blood count) have been developed although their clinical significance remains controversial. Here, we compare the diagnostic values of non-invasive markers for liver fibrosis in patients with chronic hepatitis B infection. Methods: Transient elastography and routine laboratory tests were performed in 196 patients. Diagnostic performances were compared and were assessed based on the area under the curve (AUC) of a receiver operating characteristic (ROC) analysis. Results: Elevated GGT to platelet ratio (GPR), the fibrosis index FIB-4 [based on age, AST, platelets and ALT], platelet to lymphocyte ratio (PLR) and total bilirubin were independent predictors of liver stiffness defined by transient elastography (all P < 0.001). The AUCs of GPR in predicting both advanced fibrosis and cirrhosis were significantly larger than that of FIB-4 (P = 0.037 and P = 0.008, respectively) and AST-to-platelet ratio index (APRI) (P = 0.008 and P = 0.005). FIB-4, APRI and red cell volume distribution width-to-platelet ratio (RPR) had similar diagnostic values in discriminating different levels of liver fibrosis. Conclusions: GPR showed the best diagnostic value and RPR and PLR are easily available and inexpensive markers in evaluating fibrosis and cirrhosis. The diagnostic values of these laboratory markers are useful in diagnosing advanced fibrosis or cirrhosis, and in confirming the different levels of liver fibrosis.

Abstract
Purifying selection during dengue viral infection has been suggested as the driving force of viral evolution and the higher complexity of the intra-host quasi-species is thought to offer an adaptive advantage for arboviruses as they cycle between arthropod and vertebrate hosts. However, very few studies have been performed to investigate the viral genetic changes within (intra-host) and between (inter-host) humans in a spatio-temporal scale. Viruses of different serotypes from various countries imported to Taiwan cause annual outbreaks. During 2001-2003, two consecutive outbreaks were caused by dengue virus serotype 2 (DENV-2) and resulted in a larger-scale epidemic with more severe dengue cases in the following year. Phylogenetic analyses showed that the viruses from both events were similar and related to the 2001 DENV-2 isolate from the Philippines. We comprehensively analyzed viral sequences from representative dengue patients and identified three consensus genetic variants, group Ia, Ib and II, with different spatio-temporal population dynamics. The phylodynamic analysis suggested group Ib variants, characterized by lower genetic diversity, transmission rate, and intra-host variant numbers, might play the role of maintenance variants. The residential locations among the patients infected by group Ib variants were in the outer rim of case clusters throughout the 2001-2003 period whereas group Ia and II variants were located in the centers of case clusters, suggesting that group Ib viruses might serve as "sheltered overwintering" variants in an undefined ecological niche. Further deep sequencing of the viral envelope (E) gene directly from individual patient serum samples confirmed the emergence of variants belonging to three quasi-species (group Ia, Ib, and II) and the ancestral role of the viral variants in the latter phase of the 2001 outbreak contributed to the later, larger-scale epidemic beginning in 2002. These findings enhanced our understanding of increasing epidemic severity over time in the same epidemic area. It also highlights the importance of combining phylodynamic and deep sequencing analysis as surveillance tools for detecting dynamic changes in viral variants, particularly searching for and monitoring any specific viral subpopulation. Such subpopulations might have selection advantages in both fitness and transmissibility leading to increased epidemic severity.

Abstract
One order of magnitude energy enhancement of the target surface electron beams with central energy at 11.5 MeV is achieved by using a 200 TW, 500 fs laser at an incident angle of 72° with a prepulse intensity ratio of 5×10-6. The experimental results demonstrate the scalability of the acceleration process to high electron energy with a longer (sub-picosecond) laser pulse duration and a higher laser energy (120 J). The total charge of the beam is 400±20 pC(E>2.7 MeV). Such a high orientation and mono-energetic electron jet would be a good method to solve the problem of the large beam divergence in fast ignition schemes and to increase the laser energy deposition on the target core.

Abstract
Objective: To describe trends in diet consulting at discharge for patients with acute myocardial infarction (AMI) in China from 2001-2011. Methods: A representative sample of patients in China admitted to hospital for AMI was created from a two-stage sampling approach; profiles for patients with AMI were retrospectively abstracted through their medical records.The study described the overall trends in diet consulting for patients with AMI in China, the rates of diet consulting among patients with hypertension, diabetes, and hyperlipidemia, and the variation in diet consulting across different regions. Results: We sampled 162 hospitals and included 16 100 patients with AMI in total.The weighted rates of diet consulting at AMI discharge in China was 16.5%, 28.8%, and 40.8% in 2001, 2006 and 2011, respectively (P for trend <0.001). The rates and trends among patients with hypertension, diabetes, and hyperlipidemia were similar to those among all patients with AMI (hypertension: 16.4%, 31.4%, and 41.1% in 2001, 2006 and 2011, respectively; diabetes: 18.2%, 32.2%, and 42.8%; hyperlipidemia: 18.6%, 31.4%, and 41.5%; all P for trend <0.001). The rates has not changed much for those in central rural region over the decade (19.2%, 19.4%, and 22.8% in 2001, 2006 and 2011, respectively; P for trend=0.09); meanwhile, the rates of diet consulting in other four regions increased over years (all P for trend<0.001). Conclusions: From 2001 to 2011, the rates of diet consulting at discharge for patients with AMI has increased in China; however, there are still substantial rooms for improvement, especially for central rural region.Dietitian could work with clinician and be involved in diet consulting for AMI at discharge in order to improve prognosis for patients with AMI.

Abstract
To investigate responses of milk protein synthesis and mammary AA metabolism to a graded decrease of postruminal Lys supply, 4 lactating goats fitted with jugular vein, mammary vein, and carotid artery catheters and transonic blood flow detectors on the external pudic artery were used in a 4 × 4 Latin square experiment. Goats were fasted for 24 h and then received a 9-h intravenous infusion of an AA mixture plus glucose. Milk yield was recorded and samples were taken in h 2 to 8 of the infusion period; a mammary biopsy was performed in the last hour. Treatments were graded decrease of lysine content in the infusate to 100 (complete), 60, 30, or 0% as in casein. Lysine-removed infusions linearly decreased milk yield, tended to decrease lactose yield, and tended to increase milk fat to protein ratio. Milk protein content and yield were linearly decreased by graded Lys deficiency. Mammary Lys uptake was concomitantly decreased, but linear regression analysis found no significant relationship between mammary Lys uptake and milk protein yield. Treatments had no effects on phosphorylation levels of the downstream proteins measured in the mammalian target or rapamycin pathway except for a tended quadratic effect on that of eukaryotic initiation factor 2, which was increased and then decreased by graded Lys deficiency. Removal of Lys from the infusate linearly increased circulating glucagon and glucose. Removal of Lys from the infusate linearly decreased arterial and venous concentrations of Lys. Treatments also had a significant quadratic effect on venous Lys, suggesting mechanisms to stabilize circulating Lys at a certain range. The 2 infusions partially removing Lys resulted in a similar 20% decrease, whereas the 0% Lys infusion resulted in an abrupt 70% decrease in mammary Lys uptake compared with that of the full-AA mixture infusion. Consistent with the abrupt decrease, mammary Lys uptake-to-output ratio decreased from 2.2 to 0.92, suggesting catabolism of Lys in the mammary gland could be completely prevented when the animal faced severe Lys deficiency. Mammary blood flow was linearly increased, consistent with the linearly increased circulating nitric oxide by graded Lys deficiency, indicating mechanisms to ensure the priority of the mammary gland in acquiring AA for milk protein synthesis. Infusions with Lys removed increased mammary clearance rate of Lys numerically by 2 to 3 fold. In conclusion, the decreased milk protein yield by graded Lys deficiency was mainly a result of the varied physiological status, as indicated by the elevated circulating glucagon and glucose, rather than a result of the decreased mammary Lys uptake or depressed signals in the mTOR pathway. Mechanisms of Lys deficiency to promote glucagon secretion and mammary blood flow and glucagon to depress milk protein synthesis need to be clarified by future studies.

Abstract
Neutron energy is directly correlated with the energy of the incident ions in experiments involving laser-driven nuclear reactions. Using high-energy incident ions reduces the energy concentration of the generated neutrons. A novel "laser-collider" method was used at the Shenguang II laser facility to produce monoenergetic neutrons via (7)Li (d, n) nuclear reactions. The specially designed K-shaped target significantly increased the numbers of incident d and Li ions at the keV level. Ultimately, 13.3 MeV neutrons were obtained. Considering the time resolution of the neutron detector, we demonstrated that the produced neutrons were monoenergetic. Interferometry and a Multi hydro-dynamics simulation confirmed the monoenergetic nature of these neutrons.
