ABSTRACT

Objective To analyze the prevalence of myopic refractive error and its associated risk factors among primary school students in Shanghai Minhang Distict. Methods A total of 11 356 primary school students who participated in the children's refraction screening project in Meilong Community, Minhang District, Shanghai from January 1 to December 31, 2019 were selected for visual inspection and computer optometry Results The detection rate of myopic refractive error among 6-10 year-old students was 45.59%, with a higher rate in girls and older age group. The detection rates of 6-10 year-old students were 22.88% (6 year-old), 31.77% (7 year-old), 47.62% (8 year-old), 60.53% (9 year-old) and 69.84% (10 year-old), respectively, showing a linear trend(χ 2=1.31, P<0.001). Multivariate logistic regression revealed that myopic refractive error was statistically significantly associated with gender, age and parents' myopic. Birth weight, preterm birth and body mass index (BMI) had no influence on refractive myopic in primary school students. Conclusion Myopic refractive error is still a major public health problem in primary school students. A combined strategies for myopic refractive error reduction should be called to focus on high risk persons and behaviors.

ABSTRACT

In recent years, fibroblast activation protein (FAP) has emerged as an attractive target for the diagnosis and radiotherapy of cancers using FAP-specific radioligands. Herein, we aimed to design a novel 18F-labeled FAP tracer ([18F]AlF-P-FAPI) for FAP imaging and evaluated its potential for clinical application. The [18F]AlF-P-FAPI novel tracer was prepared in an automated manner within 42 min with a non-decay corrected radiochemical yield of 32 ± 6% (n = 8). Among A549-FAP cells, [18F]AlF-P-FAPI demonstrated specific uptake, rapid internalization, and low cellular efflux. Compared to the patent tracer [18F]FAPI-42, [18F]AlF-P-FAPI exhibited lower levels of cellular efflux in the A549-FAP cells and higher stability in vivo. Micro-PET imaging in the A549-FAP tumor model indicated higher specific tumor uptake of [18F]AlF-P-FAPI (7.0 ± 1.0% ID/g) compared to patent tracers [18F]FAPI-42 (3.2 ± 0.6% ID/g) and [68Ga]Ga-FAPI-04 (2.7 ± 0.5% ID/g). Furthermore, in an initial diagnostic application in a patient with nasopharyngeal cancer, [18F]AlF-P-FAPI and [18F]FDG PET/CT showed comparable results for both primary tumors and lymph node metastases. These results suggest that [18F]AlF-P-FAPI can be conveniently prepared, with promising characteristics in the preclinical evaluation. The feasibility of FAP imaging was demonstrated using PET studies.

ABSTRACT

Objective:To analyze the prevalence of malnutrition in stable-phase elderly patients with chronic obstructive pulmonary disease (COPD) using the Global Leadership Initiative on Malnutrition (GLIM) criteria.Methods:Using cross-sectional survey, 60 elderly patients with COPD in stable phase were investigated, with 72 elderly patients without COPD in the same age group selected as controls. Differences in basic characteristics, anthropometric indicators, hematology indicators and body composition were compared between the two groups. According to the GLIM diagnostic criteria for malnutrition, the first step is nutritional risk screening, the second step is to diagnose malnutrition, and the third step is to determine severe malnutrition. The prevalence of malnutrition and severe malnutrition were investigated.Results:The levels of total protein, albumin, creatinine, and lymphocyte percentage in the elderly stable COPD group were significantly lower than those in the control group. The nutritional risk and the prevalence of malnutrition in elderly COPD patients were significantly higher than those in the control group, and the prevalence of severe malnutrition was higher .Conclusions:Elderly stable COPD patients of different age groups have a higher nutritional risk. The onset age of malnutrition is younger than that of non-COPD patients and early intervention is required.

ABSTRACT

Objective:To investigate the effects of noninvasive positive pressure ventilation combined with positive expiratory pressure device on pulmonary function, inflammatory factors and short-term prognosis in older adult patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD), which provide objective evidence for clinical treatment and prognosis evaluation of this disease.Methods:Eighty-three older adult patients with AECOPD who received treatment in Taizhou Central Hospital, China between January 2016 and December 2018 were included in this study. They were randomly assigned to undergo either noninvasive positive pressure ventilation (control group, n = 38) or noninvasive positive pressure ventilation combined with positive expiratory pressure device (study group, n = 45) for 7 days. Pulmonary function, blood gas indexes, inflammatory factor levels and curative effect were compared between the two groups. Results:After treatment, partial pressure of oxygen (PaO 2) and oxygenation index (PaO 2/FiO 2) in each group were significantly increased, and partial pressure of carbon dioxide (PaCO 2) was significantly decreased, compared with before treatment (all P < 0.05). The degree of improvement in PaO 2, PaCO 2 and PaO 2/FiO 2 in the study group was greater than that in the control group ( t = 2.261, 6.854, 2.040, all P < 0.05). The ratio of forced expiratory volume in the first second (FEV 1) to forced vital capacity (FEV 1/FVC), the ratio of FEV1 to predicted value (FEV 1/Pre), and the maximum voluntary ventilation (MVV) per minute in each group were significantly increased compared with before treatment. After treatment, the degree of increase in FEV 1/FVC, FEV 1/Pre, and MVV in the study group was greater than that in the control group ( t = 2.442, 2.120, 2.944, all P < 0.05). After treatment, serum levels of inerleukin-8, tumor necrosis factor-α, and high-sensitivity C-reactive protein in each group were significantly decreased compared with before treatment (all P < 0.05). After treatment, the degree of decrease in serum levels of inerleukin-8, tumor necrosis factor-α, and high-sensitivity C-reactive protein in the study group was significantly greater than that in the control group ( t =7.978, 10.857, 8.543, all P < 0.05). Length of hospital stay, duration of antibiotic use, chronic obstructive pulmonary disease assessment test score and St. George's Respiratory Questionnaire score in the study group were (7.52 ± 1.38) days, (7.14 ± 1.38) days, (18.95 ± 4.76) points, (1.73 ± 4.21) points, respectively, which were significantly shorter/lower than those in the control group [(8.55 ± 1.47) days, (8.25 ± 1.45) days, (8.07 ± 5.81) points, (55.97 ± 5.28) points, t = -2.510, -2.722, -7.943, -10.351, all P < 0.05]. Conclusion:Noninvasive positive pressure ventilation combined with positive expiratory pressure device can effectively improve the pulmonary function of older adult patients with AECOPD, decrease the level of inflammatory factors, and improve short-term prognosis. This study is highly innovative and scientific and is of significance for clinical promotion.

ABSTRACT

Objective:The aim of the present study was to observe the effects of liralutide on body composition and muscle function in adult obese patients with type 2 diabetes.Method:A total of 63 adult obese type 2 diabetic patients who were (52.6±9.7) years of age and with body mass index (BMI) of ≥28 kg/m 2 were enrolled. The patients were randomly assigned into two groups. On the basis of maintaining the original hypoglycemic regimen, patients in the control group ( n=24) were given dietary guidance only, and those in the treatment group ( n=39) were injected with liraglutide. All patients were followed up for a period of 12 weeks. Blood glucose, glycosylated hemoglobin(HbA1c) and insulin levels, liver and kidney function, body composition assessed with electrical impedance methods, and grip strength measured by a grip meter for muscle function were detected at the baseline and the end of the study. Results:Compared with those in the control group, the reductions in HbA1c [(-1.54±2.10) % vs.(-0.53±0.84) %], body weight [(-3.46±4.2) kg vs.(-0.34±3.66) kg], body fat mass [(-1.97±2.98) kg vs.(-0.01±2.16) kg] and visceral fat area [(-0.01±2.16) cm 2 vs.(0.34±6.39) cm 2] were more pronouced in liraglutide treated group (all P<0.05). However, no changes could be observed in muscle mass and grip strength after liraglutide treatment. Conclusions:In addition to reducing blood glucose, body weight and fat mass, treatment with lilaluptide had no impact on muscle mass and muscle function. Therefore, liralutide is suitable for obese patients with type 2 diabetes, especially for weight management patients who are at risk of muscle loss.

ABSTRACT

Objective:To investigate the stability and feasibility of improved silent MRA technique based on hybrid-arterial spin labeling(ASL) for imaging intracranial arterial stenosis.Methods:From September 2019 to May 2020, totally 35 patients with suspected intracranial vascular stenosis in Department of Neurology of Northern Jiangsu People′s Hospital were enrolled in this study. Silent MRA and improved silent MRA based on hybrid-ASL technique were performed respectively. The acquisition noise (noise measurement and subjective score) of two kinds of MRA examination were evaluated respectively. Two neuroradiologists performed image quality scoring and signal-to-noise ratio (SNR) measurement of intracranial arteries (including internal carotid artery, vertebrobasilar artery, anterior cerebral artery, middle cerebral artery, and posterior cerebral artery) in the two kinds of MRA images using a double-blind, completely randomized method. Independent sample t-test was used to compare the image quality and SNR of two kinds of MRA images in each segment. Two experts assessed the degree of stenosis at the site of confirmed intracranial artery stenosis. Kappa test was used to assess interobserver and intermodel agreement. Results:There was no significant difference in acquisition noise between improved silent MRA and silent MRA ( P>0.05). In all five segments measured, the image quality scores of internal carotid artery [(4.40±0.49)scores], anterior cerebral artery[(4.30±0.33)scores] and middle cerebral artery [(4.46±0.34)scores] in improved silent MRA were higher than those in silent MRA images [(4.02±0.43)scores, (4.02±0.31)scores, (4.02±0.31)scores; t=2.825, 2.877, 1.683, all P<0.05)]. The SNR of internal carotid artery (9.11±1.23) and middle cerebral artery (8.77±1.87) in improved silent MRA images was higher than that in silent MRA images (7.83±1.33, 8.06±2.67, respectively; t=11.154, 3.268, both P<0.05). A total of 24 patients (38 lesions) with intracranial vascular stenosis were diagnosed by CTA. Improved silent MRA (Kappa=0.89, 95%CI 0.82-0.95) and silent MRA (Kappa=0.85, 95%CI 0.77-0.92) were highly consistent among observers in evaluating the degree of cerebrovascular stenosis.The results of improved silent MRA were highly consistent with those of CTA (Kappa=0.92, 95%CI 0.87-0.98), and those of silent MRA were highly consistent with those of CTA (Kappa=0.85, 95%CI 0.77-0.92). Conclusions:The improved silent MRA is feasible to improve the imaging quality and signal uniformity through efficient marking based on keeping the low noise features. In the diagnosis of intracranial stenosis and occlusive disease, the stability of improved silent MRA imaging improves the diagnostic efficiency of stenosis to a certain extent.

ABSTRACT

Objective:To investigate the muscular quality and its related influencing factors in elderly with sarcopenic obesity.Methods:The internalized 696 elderly subjects meeting inclusion and exclusion criteria were divided into four groups including the sarcopenic obesity(n=55), sarcopenia(n=8), simple obesity(n=481)and normal control(n=152)groups.The intergroup difference was retrospectively analyzed in the parameters of body composition, dietary intake of total energy and three major nutrients and their proportions.Multiple linear regression analysis was used to analyze the influencing factors related to the occurrence of sarcopenic obesity in the elderly.Results:The sarcopenic obesity group versus normal control group showed a higher level or value in age, body mass index, waist-hip ratio, fat mass, percentage of body fat, visceral fat area, fasting blood glucose, estimated glomerular filtration rate( P<0.01 or 0.05), and showed a lower level or value in grip strength, skeletal muscle, skeletal muscle index, muscle quality(grip strength/limb skeletal muscle), intake of energy, carbohydrate, fat and protein, body weight-adjusted intake of energy and protein, as well as ideal body weight-adjusted intake of energy and protein( P<0.01). The detection rate of sarcopenic obesity was 7.90%(n=55), including 7.60% in males(n=48)and 11.48% in females(n=7 cases). The detection rate of sarcopenic obesity was increased along with increasing age with 0.07%(2/287)in 60-69 years old group, 4.94%(12/243)in 70-79 years old group, and 24.70%(41/166)in ≥80 years old group( χ2=87.76, P<0.01). Taking the median point of grip strength/limb skeletal muscle volume as the cutoff point, the decrease rate of muscle quality was 12.36%(86/696)in total elderly subjects, 2.63%(4/152)in the control group, 11.64%(86/635)in the obesity group, 37.5%(3/8)in the sarcopenia group and 41.82%(23/55)in the sarcopenic obesity group, with an increasing trend of the decrease of muscle quality, which had significant differences( χ2=62.25, P<0.01). Multiple logistic regression analysis showed that aging, excessive visceral fat area, insufficient protein intake and decreased basal metabolism were the independent risk factors for sarcopenic obesity in elderly people( P<0.01 or P<0.05). Conclusions:The incidence of decrease of muscle quality is higher in the elderly with sarcopenic obesity than other elderly groups.Sarcopenic obesity is correlated with aging, insufficient intake of protein, decreased basal metabolism and excessive visceral fat accumulation.Individual evaluation and support is necessary in elderly people with sarcopenic obesity.

ABSTRACT

Objective:To analyze influencing factors for sarcopenia in people of advanced age, in order to provide insight and evidence for the prevention and treatment of sarcopenia in people belonging to this age group.Methods:Data from 167 people of advanced age seeking care at our department from December 2014 to July 2017 were retrospectively analyzed.According to the diagnostic criteria for sarcopenia of the Asian Working Group for Sarcopenia, subjects were divided into the sarcopenia group( n=46, 27.5%)and the non-sarcopenia group( n=121). Differences in body composition, energy intake, quantities and proportions of three major nutrients were analyzed between males and females.Related influencing factors for sarcopenia were analyzed by using multiple linear regression. Results:Compared with the non-sarcopenia group, the sarcopenia group had lower body mass index, waist-hip ratio, fat mass, total energy intake and protein( P<0.05)but higher age and fat intake( P<0.05). Values for grip strength, muscle mass, index of skeletal muscle, adjusted muscle mass by body mass index, total energy intake, carbohydrates, fat and protein were lower and the percentage of body fat was higher in females than in males( P<0.05). Multiple Logistic regression analysis showed that insufficient intake of protein( β=-0.290, OR=0.748, 95% CI: 0.569-0.984, P<0.05), reduction of body fat mass( β=-2.673, OR=0.069, 95% CI: 0.010-0.488, P<0.05)and excessive visceral fat accumulation( β=0.739, OR=2.094, 95% CI: 1.219-3.597, P<0.01)were correlated with sarcopenia in people of advanced age. Conclusions:The occurrence of sarcopenia is higher in people of advanced age and is related to insufficient intake of protein, reduction of body fat mass and excessive visceral fat accumulation.Individualized nutrition evaluation and support should be carried out as early as possible for people in this age group.

ABSTRACT

ObjectiveTo screen out differentially expressed genes (DEGs) and related candidate therapeutic drugs for acute pancreatitis (AP) using the bioinformatics method. MethodsHigh-throughput microarray datasets (GSE109227 and GSE65146) associated with AP in mice were downloaded from gene expression omnibus, and GEO2R was used to screen out DEGs. Database for Annotation, Visualization and Integrated Discovery was used to perform gene ontology and pathway enrichment analysis. Protein-protein interaction (PPI) was established in String database and visualized by Cytoscape, and then subnetwork modules and hub genes were screened out. The microRNAs associated with the hub genes were predicted and candidate drugs were screened out using Comparative Toxicogenomics Database (CTD). ResultsA total of 130 upregulated and 16 downregulated DEGs were screened out in the high-throughput microarray datasets GSE109227 and GSE65146. DEGs were mainly involved in the biological processes such as inflammatory response, neutrophil chemotaxis, tumor necrosis factor-mediated cellular response, and positive regulation of gene expression, and they were also involved in the signaling pathways of extracellular matrix-receptor interaction, regulation of actin cytoskeleton, leukocyte transendothelial migration, and focal adhesion. A total of 12 hub genes and 6 subnetwork modules were screened out in the PPI network. The microRNAs including miR-199a-5p and miR-1-3p might regulate the post-transcriptional regulation of key genes. Genistein, resveratrol, and quercetin which were screened out from CTD database could reduce the expression of key genes. ConclusionRelated genes screened out by the bioinformatics method may play an important role in the development of AP and can be used as the basis for drug screening.

ABSTRACT

OBJECTIVE:To study the anti-tumor effect of artemether (ARM)self-microemulsifying drug delivery system (SMEDDS) on human glioma subcutaneously transplanted model mice. METHODS :Human glioma cell line SHG 44 was inoculated and passed on to establish subcutaneous transplanted tumor model of nude mice. At the 5th,10th,15th,20th and 25th day after inoculation ,the tumor tissue volume was measured and the growth curve was drawn to confirm the initial stage of rapid tumor proliferation. Thirty nude mice was collected to establish subeutaneously transplanted tumor nude model ,and then divided into control group (normal saline ),ARM suspension group [ 60 mg/(kg·d)],ARM-SMEDDS low-dose ,medium-dose and high-dose groups [ 10,20,30 mg/(kg·d)] at the initial stage of rapid tumor proliferation. They were given normal saline and relevant solution intragastrically once a day ,for consecutive 30 d. The weight change and general sibuation of mice were recorded. The change of tumor volume was determined and relative tumor proliferation rate was calculated. RESULTS :The subcutaneously transplanted tumor tissue entered the initial stage of rapid tumor proliferation from the 10th day after transplantation. The general situation was normal ,and there was no obvious abnormal reaction in mice of each group during treatment. Since 10th day of administration,tumor tissue volume of mice in ARM-SMEDDS groups were shortened significantly than control group (P<0.05). At 15th day of administration ,tumor volume of mice in ARM-SMEDDS groups were shortened significantly than ARM suspension group(P<0.05). After last administration ,relative tumor proliferation rates of mice in ARM-SMEDDS groups were decreased significantly,compared with ARM suspension group (P<0.05). CONCLUSIONS :ARM-SMEDDS show significant inhibitory effect on the proliferation of human glioma ,and are better than suspension with higher dosage.

ABSTRACT

OBJECTIVE@#To analyze variant of IDS gene in a pedigree affected with mucopolysaccharidosis type II (MPS II).@*METHODS@#The proband was subjected to next generation sequencing and Sanger sequencing to identify potential variants. Suspected variant was analyzed by its co-segregation with the disease in the pedigree. Its impact on mRNA splicing was analyzed by using reverse transcription PCR (RT-PCR).@*RESULTS@#A hemizygous IVS1-3T>G variant was found in the IDS gene in the proband. RT-PCR results revealed two abnormal cDNA fragments of 600 bp and 300 bp. The 600 bp fragment had inserted 216 nucleotides at the 3' end of intron 1, while the 300 bp fragment had lost 109 nucleotides at the 5' end of exon 2, which resulted in two truncated proteins comprising 38 and 92 amino acids, respectively, instead of the normal product (550 amino acids). The proband and his mother were respectively hemizygous and heterozygous for the variant. The same variant was not found among 100 normal controls.@*CONCLUSION@#The IVS1-3T>G variant of the IDS gene probably underlies the MPS II in this pedigree by causing reduction or elimination of the IDS protein.

Objective:To evaluate the efficacy of ultrasound-guided sacral canal block for anesthesia in neonatal anoplasty.Methods:Sixty neonats with anal atresia, of American Society of Anesthesiology physical status ⅠorⅡ, were divided into 2 groups ( n=30 each) by a random number table method: traditional positioning method for sacral canal block group (group T) and ultrasound-guided sacral canal block group (group U). After successful puncture, 0.2% ropivacaine 1 ml/kg was injected in both groups.The success of puncture at first attempt, puncture time, successful sacral canal block and occurrence of adverse reactions were recorded. Results:Compared with group T, the success rate of puncture at first attempt was significantly increased, the puncture time was shortened ( P<0.05), and no significant change was found in the success rate of sacral canal block in group U ( P>0.05). Neonatal sacrococcygeal contents and the termination of the neonatal dural sac were observed under ultrasound in group U. Blood return in the puncture needle was observed in one case in group T, and no adverse reactions were found in group U. Conclusion:Ultrasound-guided sacral canal block provides better efficacy than the traditional sacral canal block when used for anesthesia in neonatal anoplasty.
