Abstract
BACKGROUND Inappropriate antimicrobial prescribing may harm patients and drive antimicrobial resistance. Junior doctors' knowledge of infectious diseases and antimicrobial prescribing is inadequate. Online spaced case-based learning can improve knowledge. OBJECTIVE To develop infectious diseases and antimicrobial prescribing course content for online spaced education and assess its effectiveness and feasibility for junior doctors. METHODS Infectious diseases and antimicrobial course content was developed for an online spaced education platform (Qstream Inc., Burlington, MA). Junior doctors (postgraduate years 1-3) at two tertiary teaching hospitals in Sydney participated in the study. Course content was provided with Qstream at one hospital and at the other hospital via two face-to-face (FTF) tutorials from August to October 2017. Knowledge and self-confidence were compared before and after training within and between both cohorts. RESULTS Participation in the course was higher in the Qstream cohort with 48/127 (37.8%) completing the course compared with 44/110 (40%) attending one or both FTF sessions, of whom 22/110 (20%) attended both. Improvement in mean knowledge score from 69.7% to 81.5% in the Qstream cohort was significantly greater than the FTF cohort's minimal improvement from 67.6% to 67.9% (95% CI 2.79-20.33; P=0.01). In the Qstream cohort mean confidence rating (0-10) improvement from 5.14 to 6.55 was greater than the FTF group improvement from 5.37 to 5.85 (95% CI 0.132-1.171; P=0.02). Qstream feedback was very positive. CONCLUSIONS Online spaced education in infectious diseases and antimicrobial prescribing was feasible, acceptable and effective for junior doctors. It has potential to reduce inappropriate antimicrobial prescribing and warrants further investigation.

Abstract
Ginkgo biloba L. is a relic tree that is preserved in natural conditions only in China. In the North-East Ukraine ginkgo is only in the process of introduction, but in certain places ginkgo trees are grown for decorative purposes which show high vitality. Therefore a relevant and promising task is the creation of industrial plantations of ginkgo for collection of its leaves. The objective of the study was morphological peculiarities of ginkgo plants and their vital condition depending on the calendar age of the seedlings at the stage when they were transplanted into the soil. For growing ginkgo, in our studies, a combined two-stage system was approbated, according to which seedlings were grown in greenhouses during 2–3 years, and then moved into soil outdoors. In our study, as planting material we used seedlings of ginkgo from a plant nursery (greenhouse) of Sumy National Agrarian University planted in 2014 and 2015. Seedlings were planted in the soil in early spring. Seedlings for growth completion were planted in rows with inter-row distance of 0.8 m and distance between the plants measuring 2.5–3.0 m. We studied the condition of the seedlings in two variants: variant 1 – three-year old seedlings obtained in the greenhouse were transplanted in spring 2018; variant 2 – two-year old seedlings obtained in greenhouse were transplanted in spring 2017. Comparative morphometric analysis and evaluation of vitality of these plants was performed in August 2019. Both groups of seedlings were five years old at the time of survey. For evaluation of morphometric structure of the ginkgo seedlings and their vital condition we used randomized selections of specimens in amount of up to 30 from plantations of variants 1 and 2. Analysis of the plants was conducted during the end of the vegetative period of 2019, when active growth of the plants stopped. Four main parameters of the plants were recorded: height, value of annual increment, diameter of the stem near the root neck and the number of leaves. Vital condition of the seedlings was evaluated on the basis of algorithm of vital analysis. Vitality of each seedling was evaluated by the coefficient of Q vitality, value of which was in interval from 0 to 1.0. Depending on the value of Q the seedlings were divided into five classes of vitality: 0–0.2 – cc (specimens of the lowest vitality), 0.2–0.4 – c (low vitality), 0.4–0.6 – b (average vitality), 0.6–0.8 – a (high vitality), 0.8–1.0 – aa (specimens with highest vitality). Comparative analysis of morphological peculiarities of the ginkgo seedlings revealed that two-year plants transplanted outdoors from the greenhouse had higher annual increment of the main stem, diameter of stem and number of leaves. Vital condition of such seedlings was the highest and was evaluated using Q index, which ranges between vitality of classes b to aa. This allows recommending a two-stage scheme of growing seedlings of ginkgo in North-East Ukraine. The optimum age for transplanting seedlings from greenhouses to open soil is two years.

Abstract
This study investigated protective effects of mannan oligosaccharide (MOS) inclusion on growth performance, intestinal oxidative status, and barrier integrity of cyclic heat-stressed broilers. A total of 240 one-day-old chicks were allocated into 3 treatments of 10 replicates each. Control broilers reared at a thermoneutral temperature were fed a basal diet, whereas broilers in heat stress and MOS groups raised at a cyclic high temperature (32 to 33°C for 8 h/d) were given the basal diet supplemented with 0 or 250 mg/kg MOS, respectively. Compared with control group, heat stress decreased (P < 0.05) average daily gain and feed conversion ratio during grower, finisher, and entire periods, average daily feed intake during finisher and entire periods, and ileal superoxide dismutase activity at 42 D, whereas increased (P < 0.05) rectal temperature at 21 and 42 D and jejunal malondialdehyde content at 42 D. Dietary MOS increased (P < 0.05) average daily gain, average daily feed intake, and feed conversion ratio during finisher and entire periods, but decreased (P < 0.05) jejunal malondialdehyde concentration of heat-stressed broilers at 42 D. Heat stress decreased (P < 0.05) jejunal villus height (VH) and claudin-3 gene expression at 21 D, and VH and VH: crypt depth (CD) ratio in jejunum and ileum as well as mRNA abundances of jejunal mucin 2 and occludin, and ileal mucin 2, zonula occludens-1, and occludin, and claudin-3 at 42 D, whereas increased (P < 0.05) serum D-lactate acid content at 21 and 42 D, and serum diamine oxidase activity and jejunal CD at 42 D. The MOS supplementation increased (P < 0.05) jejunal VH at 21 D, VH and VH: CD of jejunum and ileum at 42 D, mRNA abundances of jejunal occludin and ileal mucin 2, zonula occludens-1, and occludin at 42 D, whereas reduced (P < 0.05) ileal CD at 42 D. These results suggested that MOS improved growth performance, and oxidative status and barrier integrity in the intestine of broilers under cyclic heat stress.

Abstract
Objective: To analyze the clinical characteristics of newly treated high-risk group neuroblastoma (NB) patients with bone marrow metastasis and to explore the prognostic factors. Methods: The clinical features (sex, age, stage, risk group, pathological type, metastatic site, etc.) of 203 newly treated high-risk NB patients with bone marrow metastasis admitted to Hematology Oncology Center, Beijing Children's Hospital from January 2007 to December 2016 were analyzed retrospectively. There were 118 males (58.1%) and 85 females (41.9%). Kaplan-Meier method was used for survival analysis and Cox regression was used to analyze the prognostic factors. Results: The age at onset of the 203 patients was 41 months (9-147 months). The metastatic sites at diagnosis were as follows: bone in 195 cases (96.1%), distant lymph nodes in 104 cases (51.2%), skull and endomeninx in 61 cases (30.0%), orbit in 30 cases (14.8%), pleura in 16 cases (7.9%), liver in 13 cases(6.4%), canalis spinalis in 13 cases (6.4%), other sites in 11 cases (5.4%) and skin and soft tissue in 10 cases (4.9%). In all, 194 cases were enrolled for prognostic analysis. The follow-up time was 36 months (1 day-138 months) , and the 5-years event free survival (EFS) and overall survival (OS) were 36.1% and 39.7%, respectively. A total of 118 patients (60.8%) had events (first relapse or death) with the time to event occurrence was 15 months (1 day-72 months), whereas 112 patients (57.7%) died with the event occurrence to death time was 3 months (1 day-21 months). There was no significant difference in 5-years OS between radiotherapy group and non-radiotherapy group (42.3% vs. 38.3%, χ(2)=3.671, P=0.055). The 5-years OS in transplantation group was significantly better than the non-transplantation group (44.3% vs. 35.5%, χ(2)=8.878, P=0.003), and the radiotherapy combined transplantation group also had a better 5-years OS rate than the non-radiotherapy combined transplantation group (45.8% vs. 37.3%, χ(2)=5.945, P=0.015). Univariate survival analysis showed lactate dehydrogenase ≥ 1 500 U/L, the amplification of MYCN, the metastatic sites of orbit, canalis spinalis and pleura were associated with poor prognosis of newly diagnosed high-risk NB patients (χ(2)=21.064, 13.601, 3.998, 6.183, 15.307, all P<0.05). The amplification of MYCN and the metastatic sites of pleura were risk factors for prognosis of newly diagnosed high-risk NB patients by Cox regression models (HR=1.896,1.100, 95%CI: 1.113-3.231, 1.020-1.187, both P<0.05). Conclusions: The prognosis is unfavorable in high-risk group NB patients with BM metastasis. Radiotherapy combined with transplantation can further improve the prognosis of these patients. The amplification of MYCN and the metastatic sites of pleura were the poor prognostic factors for high-risk NB patients with bone marrow metastasis.

Abstract
Objective: To summarize the clinical characteristics, treatment response and prognostic factors of rhabdomyosarcoma (RMS) in children. Methods: The clinical characteristics such as age at diagnosis, primary tumor site, tumor size, pathological type, clinical stage, and risk grouping of 213 RMS patients (140 males and 73 females) treated in Hematology Oncology Center of Beijing Children's Hospital, Capital Medical University, from May 2006 to June 2018 were analyzed retrospectively. The clinical characteristics, overall survival (OS), event free survival (EFS) and prognostic factors of children treated with the Beijing Children's Hospital-Rhabdomyosarcoma (BCH-RMS) regimen were analyzed. Survival data were analyzed by Kaplan-Meier survival analysis, and single factor analysis was performed by Log-Rank test. Results: The diagnostic age of 213 cases was 48.0 months (ranged 3.0-187.5 months), of which 136 cases (63.8%) were younger than 10 years old. The head and neck region was the most common primary site of tumor (30%, 64 cases), followed by the genitourinary tract (26.8%, 57 cases). Among pathological subtypes, embryonal RMS accounted for 71.4% (152 cases), while alveolar RMS and anaplastic RMS accounted for only 26.8% (57 cases) and 1.9% (4 cases), respectively. According to the Intergroup Rhabdomyosarcoma Study Group (IRS), IRS-Ⅲ and Ⅳ accounted for 85.0% (181 cases) of all RMS patients. In all patients, 9.4% (20 cases) patients were divided in to low-risk group, 52.1% (111 cases) patients in to intermediate -risk group, 25.8% (55 cases) patients in to high-risk group, and 12.7% (27 cases) patients in to the central nervous system invasion group, respectively. All patients with RMS received chemotherapy. The cycles of chemotherapy were 13.5 (ranged 5.0-18.0) for patients without event occurrence, while 14.2 (ranged 3.0-30.0) for patients with event occurrence. Among the 213 patients, 200 patients had surgical operation, of whom 103 patients underwent surgery before chemotherapy and 97 patients at the end of chemotherapy, 21 patients had secondary surgical resection. Radiotherapy was performed in 114 patients. The follow-up time was 23.0 months (ranged 0.5-151.0 months) . There were 98 patients with relapsed or progressed disease and 67 patients with death. The median time to progression was 10 months, of which 67 (68.4%) relapse occurred within 1 year and no recurrence occurred after follow-up for more than 5 years. The 3-year EFS and 5-year EFS were (52±4) % and (48±4) %, while the 3-year OS and 5-year OS were (65±4) % and (64±4) % by survival analysis. The 5-year OS of the low-risk, intermediate-risk, the high-risk were 100%, (74±5) %, (48±8) %, and the 2-year OS of the central nervous system invasion group was (36±11) % (χ(2)=33.52, P<0.01). The 5-year EFS of the low-risk, intermediate-risk, the high-risk were (93±6) %, (51±5) %, (36±7) % and the 2-year EFS of the central nervous system invasion group was (31±10) % (χ(2)=24.73, P<0.01) . Survival factor analysis suggested that the OS of children was correlated with age(χ(2)=4.16, P=0.038), tumor TNM stage (χ(2)=22.02, P=0.001), IRS group (χ(2)=4.49, P<0.01) and the risk group (χ(2)=33.52, P<0.01). Conclusions: This study showed that the median age of newly diagnosed RMS patients was 4 years. The head and neck and the genitourinary tract were the most common primary origin of RMS. The OS was low in single-center RMS children. The median time to recurrence was 10 months, and recurrence was rare 3 years later.

Abstract
Abstract
Background
Galectin-3 (Gal-3) is a clinical biomarker for risk of cardiovascular disease and a disease mediator forming a therapeutic target. However, the mechanism(s) that regulate cardiac expression of Gal-3 remains unknown. Activation of the sympatho-β-adrenergic system is a hallmark of heart disease, but the relationship of βAR activation and cardiac content of Gal-3 remains unknown.
Purpose
To determine the role of βAR activation in regulating cardiac Gal-3 level and the responsible mechanism focusing on the Hippo signalling pathway.
Methods
Wild-type and Gal-3 gene deleted (Gal3-KO) mice were used. To test the role of the Hippo pathway, we used transgenic (TG) mouse strains with cardiac overexpression of mammalian-20-like sterile kinase 1 (Mst1, mammalian orthology of Drosophila Hippo kinase) either in wild-type form (TG-Mst1) or dominative-negative kinase dead mutant form (TG-dnMst1). Effects of β-antagonist (isoprenaline, ISO) and antagonists were determined. We measured phosphorylation (Ser127) of YAP as a transcription co-regulator acting as the main signal output of the Hippo pathway.
Results
In wild-type mice, treatment with ISO led to a time- and dose-dependent increase in cardiac expression of Gal-3 (Fig. A) accompanied by elevated circulating Gal-3 levels (Fig. B). ISO treatment stimulated cardiac expression of Mst1 and YAP hyper-phosphorylation (i.e. inactivation, Fig. C), indicating activation of the Hippo signalling. These effects of ISO were inhibited by β-blockers (propranolol, Prop; carvedilol, Carv; Fig. D,E). Relative to non-TG controls, ISO-induced expression of Gal-3 was inhibited by 75% in TG-dnMst1 mice (inactivated Mst1), but exaggerated by 7-fold in TG-Mst1 mice (activated Mst1). Mst1-TG mice had a 45-fold increase in Gal-3 content, YAP hyper-phosphorylation and enhanced pro-fibrotic signaling. In Mst1-TG mice, whilst blood Gal-3 level was unchanged, treatment with ISO (6 mg, 2 days) evoked a marked increase in cardiac and blood Gal-3 levels. Using rat cardiomyoblasts, we showed that ISO-mediated Mst1 expression and YAP phosphorylation were PKA-dependent and that siRNA-mediated YAP knockdown led to Gal-3 upregulation. The role of Gal-3 in mediating ISO-induced cardiomyopathy was examined by treating wild-type and Gal3-KO mice with ISO (30 mg/kg, 7 days). ISO-treated wild-type mice had 8-fold increase in cardiac Gal-3, ventricular dysfunction, fibrosis, hypertrophy and activated inflammatory or fibrotic signalling. All these changes, except hypertrophy, were abolished by Gal3-KO.
beta-AR regulates galectin-3
Conclusion
βAR stimulation increases cardiac expression of Gal-3 through activation of the Hippo signalling pathway. This is accompanied by elevated circulating Gal-3 level. βAR antagonists inhibited βAR-Mst1 (Hippo) signalling and cardiac Gal-3 expression, actions likely contributing to the overall efficacy of β-blockers.

Abstract
AIMS In order to understand the response of soil microbial communities to the long-term of decomposed straw return, the modifications of soil microbial community structure and composition induced by more than 10 years of fresh and decomposed straw return was investigated and the key environmental factors were analysed. METHODS AND RESULTS Phospholipid fatty acid analysis and high-through sequencing technique were applied to analyse the structure and composition of the soil microbial communities. Compared with fresh straw, returning decomposed straw increased the relative abundance of bacteria and fungi by 1·9 and 7·7% at a rate of ~3750 kg ha-1 , and increased by 23·1 and 5·7%, at a rate of ~7500 kg ha-1 respectively. The relative abundance of the bacteria related to soil nitrification increased, but the ones related to soil denitrification decreased with decomposed straw return, which led to higher total nitrogen contents in soils. Moreover, returning decomposed straw reduced pathogenic fungal populations (genus of Alternara), which had significantly positive correlation with soil electric conductivity. It indicated that the long-term of decomposed straw return might have lower risk of soil-borne disease mainly for the reasonable soil salinity. CONCLUSIONS Long-term of decomposed straw return could provide suitable nutrient and salinity for healthier development of soil microbial community, both in abundance and structure, compared with fresh straw return. SIGNIFICANCE AND IMPACT OF THE STUDY The results of the study helps to better understand how the microbial community modifications induced by decomposed straw return benefit on soil health. The obtained key factors impacting soil microbial community variations is meaningful in soil health management under conditions of straw return.

Abstract
BACKGROUND AND PURPOSE AV-1451 (18 F-AV-1451, flortaucipir) positron emission tomography was performed in C9orf72 expansion carriers to assess tau accumulation and disease manifestation. METHODS Nine clinically characterized C9orf72 expansion carriers and 18 age- and gender- matched cognitively normal individuals were psychometrically evaluated and underwent tau positron emission tomography imaging. The regional AV-1451 standard uptake value ratios from multiple brain regions were analyzed. Spearman correlation was performed to relate the AV-1451 standard uptake value ratio to clinical, psychometric and cerebrospinal fluid measures. RESULTS C9orf72 expansion carriers had increased AV-1451 binding in the entorhinal cortex compared to controls. Primary age-related tauopathy was observed postmortem in one patient. AV-1451 uptake did not correlate with clinical severity, disease duration, psychometric performance or cerebrospinal fluid markers. CONCLUSION C9orf72 expansion carriers exhibited increased AV-1451 uptake in entorhinal cortex compared to cognitively normal controls, suggesting a propensity for primary age-related tauopathy. However, AV-1451 accumulation was not associated with psychometric performance in our cohort.

Abstract
Summary Noonan syndrome with multiple lentigines(NSML) is a disorder with syndromic hearing loss. Abnormalities of other systems in NSML have received increasing attention, but hearing loss is rarely concerned. And due to the incomplete phenotype, some patients with NSML maybe missed or maybe confused with other syndromic deafness such as Waardenburg syndrome. Our study will familiarize more otolaryngologists with Leopard syndrome. A 5-year-old boy with bilateral sensorineural hearing loss and numerous symmetrically distributed dark brown macules that had good effect of cochlear implantation was collected in this study. And his father had bilateral sensorineural hearing loss and numerous symmetrically distributed dark brown macules. Waardenburg syndrome was initially diagnosed by clinical phenotype and its molecular etiology was confirmed by gene diagnosis. Waardenburg syndrome-related deafness genes and 131 known deafness genes were not identified by second-generation sequencing. Whole-exon sequencing was performed for 4 individuals in the family and the results were confirmed by Sanger sequencing. This study confirmed the diagnosis by identifying a disease-causing mutation in the PTPN11 gene, which was a heterozygous missense mutation at p. Tyr279Cys(c. 836A>G). The mutation co-segregated with hearing loss in the family. Our results demonstrated that hearing loss in this family was caused by heterozygous mutations in PTPN11. These cases will familiarize more otolaryngologists with NSML, and they emphasize the importance of considering NSML as a possible cause of hearing problems.

Abstract
For integrated optical devices and traveling-wave resonators, realistic use of the superior wave-matter interaction offered by plasmonics is impeded by ohmic loss, which increases rapidly with mode volume reduction. In this work, we report composite hybrid plasmonic waveguides (CHPWs) that are not only capable of guiding subwavelength optical mode with long-range propagation but also unrestricted by stringent requirements in structural, material, or modal symmetry. In these asymmetric CHPWs, the versatility afforded by coupling dissimilar plasmonic modes provides improved fabrication tolerance and more degrees of device design optimization. Experimental realization of CHPWs demonstrates propagation loss and mode area of 0.03 dB/μm and 0.002 μm2, corresponding to the smallest combination among long-range plasmonic structures reported to date. CHPW ring resonators with 2.5-μm radius were realized with record Purcell factor compared with existing plasmonic and dielectric resonators of similar radii.

Abstract
Alpha-fetoprotein (AFP) is a well-known tumor marker of hepatic carcinoma and yolk sac tumor. Alpha-fetoprotein producing gastric carcinoma (AFPGC) is a rare type of gastric cancer with high malignancy and poor prognosis, which make it different from other types of gastric cancer. This rare gastric cancer patient subgroup is likely frequently misdiagnosed which may be related to lack of knowledge of the disease. The purpose of this article is to summarize the mechanism of AFP positive gastric cancer, classification, biological behavior and treatment, in order to assist clinical practitioners to detect AFPGC earlier and treat it better. Previous studies have showed that AFPGC has a complex pathophysiology mechanism. AFPGC is more aggressive and characterized by stronger proliferation, neovascularization, lymphatic invasion and distant metastasis. Furthermore, so far there has been no standard treatment for patients with AFPGC. Nevertheless, our present study summarizes some effective treatments based on previous research outcome. In conclusion, the present study demonstrates that the importance of detecting AFP routinely in serum and tissues in gastric cancer cases, which will greatly improve the diagnosis rate of AFPGC, and in regards to treatment, surgery, chemotherapy, targeted therapy and interventional treatment may have positive impacts on AFPGC treatment outcome. However, further study with a larger sample is required to confirm the reliability and validity of these methods.

Abstract
Objective: To investigate the translucency parameters (TP) and the color parameters of computer-aided design and computer-aided manufacturing (CAD/CAM) materials for veneer restorations in order to guide clinical practice. Methods: Eleven groups of CAD/CAM materials (A2 shade) were included in this study: IPS e.max CAD HT/LT, IPS Empress CAD HT/LT, Lava(TM) Ultimate HT/LT, VITA SUPRINITY HT/T, VITA ENAMIC HT/T, VITABLOCS Mark Ⅱ, and were named as Group A, B, C, D, E, F, G, H, I, J, K. Each material was designed and milled to disk-shaped specimens (10.0 mm×8.0 mm×0.7 mm) (n=6). The specimens were polished with silicon carbide paper and the thickness of specimens were adjusted into (0.60±0.03) mm. The color parameters of specimens were individually measured with the colorimeter against black and white ceramic tiles background to obtain the TP values. The color parameters of the specimens against the composite resin background were also measured and the color differences (ΔE values) between specimens and the A2 shade tab were calculated. Results: One-way ANOVA showed that the translucency parameters of the 11 groups of materials were statistically significant (F=253.69, P<0.05). The ΔE values of CAD/CAM material groups ranged from 1.78 to 4.12 (ΔE values<5.5). Conclusions: The microstructure of CAD/CAM materials and the types of material translucency influence the optical properties. The CAD/CAM materials in this experiment have achieved color matching with the A2 shade tab.

Abstract
Abstract
Background: The benefit of repeat lumpectomy for ipsilateral breast tumor recurrence (IBTR) after breast conserving surgery (BCS) is currently inconclusive. This issue has become even more important as small and isolated recurrent tumors were frequently diagnosed.
Methods: IBTR patients with definitive surgery were identified in the Surveillance, Epidemiology, and End Results registry between 1973 and 2013. The effect of different IBTR surgeries on overall and cancer-specific mortality was assessed using risk-adjusted Cox proportional hazard regression modeling and stratified propensity score matching analysis (PSMA).
Results: Based on the selection criteria, 5098 patients were recruited. Of those, 4048 (79.4%) women underwent mastectomy and 1050 (20.1%) underwent repeat lumpectomy after IBTR. Patients who received repeat lumpectomy had lower grade (23.7% vs 15% for well-differentiated) and smaller recurrent tumor (47% vs 36.2% for ≤ 1 cm) but earlier recurrence (23.9% vs 11.2% for interval times < 48 months) than those who underwent mastectomy. A minority of each group (24.7% of those undergoing repeat lumpectomy and 3% of the mastectomy group) underwent RT after surgery. In multivariable Cox regression analysis, repeat lumpectomy was associated with increased overall mortality (Hazard ratio (HR) = 1.58, 95% CI = 1.353 to 1.844, P < 0.001) and cancer-specific mortality (HR = 1.721, 95% CI = 1.345 to 2.202, P< 0.001). Similar HRs were derived from the PSMA cohort. However, we found no significant difference in overall mortality for women who underwent repeat lumpectomy followed by RT compared with that for those who underwent mastectomy (P= 0.411). Moreover, IBTR patients with small tumors (≤ 1 cm) who underwent repeat lumpectomy with RT rather than without had similar overall and cancer-specific survival rates to those who underwent mastectomy (P= 0.189 and P= 0.604, respectively).
Conclusions: Our investigation suggests that compared with mastectomy, repeat lumpectomy for IBTR is associated with higher overall and cancer-specific mortality under real-world observational conditions. Furthermore, repeat lumpectomy with RT is equivalent to mastectomy with respect to overall mortality and may influence treatment decision making for patients with small IBTR.

Abstract
Objective: To analyze the relationships between cerebral blood perfusion and impairments of cognitive function in patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI). Methods: A total of 21 patients with AD, 18 patients with MCI and 21 healthy adults as control group (NC group) matched in age, gender and education were recruited between November 2016 and November 2017 from Northern Jiangsu People's Hospital. All cases were performed routine head MRI, arterial spin labeling (ASL). Cognitive function evaluation including simple mental state scale (MMSE) and improved Addenbrooke's cognitive examination revised (ACE-R) of patients were also assessed. The difference between cerebral blood perfusion signals and cognitive impairment of the three groups were analyzed. Results: The subtest scores of attention and orientation, memory, language fluency, language and visual space of ACE-R scores were significantly reduced (P<0.001,uncorrected) for AD when compared with MCI. Using REST1.8 software to perform single factor ANOVA, and adjusted for P<0.05. The AD group showed a decrease in total cerebral perfusion compared to the NC group, a decrease and in the frontotemporal lobe compared to MCI group; compared with the normal group, MCI group also showed decreased perfusion in frontotemporal cortex. Pearson correlation analysis was performed on the cerebral blood flow and ACE-R scores in the AD group and the MCI group,the decrease degree of CBF in multiple brain regions was positively correlated with the total score of ACE-R's total scores, and the subtest score of ACE-R including attention and orientation, memory, language fluency, language and visual space also showed positive correlation. Conclusion: ASL technology can detect the changes of cerebral blood flow metabolism in AD and MCI patients, and reveal association relationships between brain function damage and cerebral blood flow metabolism in AD and MCI patients.
