Abstract Objective Monitoring the disease status of Epstein-Barr virus (EBV)-related hemophagocytic lymphohistiocytosis (HLH) patients is crucial. This study aimed to investigate the different strategies and outcomes of patients with EBV-HLH and re-elevated EBV-DNA. Method A retrospective analysis was conducted on 20 patients diagnosed with EBV-HLH. Clinical features, laboratory tests, treatments, plasma EBV-DNA levels, and outcomes were assessed. Three cases were highlighted for detailed analysis. Results Nine of the 20 patients had a re-elevation of EBV-DNA during treatment, and 55.5 % (5/9) experienced relapses. Patients with persistently positive plasma EBV-DNA (n = 4) and those with re-elevated EBV-DNA after conversion (n = 9) showed a significantly higher relapse rate compared to those with persistently negative EBV-HLH (n = 7) (p < 0.05). Among the highlighted cases, Case 1 exhibited plasma EBV-DNA re-elevation after four weeks of treatment without relapse, maintaining stability with the original treatment regimen, and eventually, his plasma EBV-DNA turned negative. In Case 2, plasma EBV-DNA was elevated again with a recurrence of HLH after L-DEP. Consequently, she underwent allogeneic hematopoietic stem cell transplantation and eventually achieved complete remission (CR) with negative plasma EBV-DNA. Case 3 experienced plasma EBV-DNA re-elevation after L-DEP but remained in CR, discontinuing chemotherapy without relapse. Conclusion The re-elevation of plasma EBV-DNA during EBV-HLH treatment poses challenges in determining disease status and treatment strategies. Optimal management decisions require a combination of the level of elevated EBV-DNA, the intensity of hyperinflammation, and the patient's immune function.

ABSTRACT This study was conducted to identify the key volatile compounds that characterize whether silage has deteriorated and to investigate the intrinsic link between the key compounds and silage odor. First, silages with different aerobic exposure durations were sampled, and sensory evaluation integrating aerobic stability monitoring was used to distinguish whether the silage had deteriorated. Subsequently, headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) was utilized to determine the relative content of the compounds. Using the relative content of the compounds in each silage as input, relative odor activity value (ROAV) calculations and orthogonal partial least squares discriminant analysis (OPLS-DA) were performed to determine the odor contribution of the compounds and the compounds with significant differences in relative content (based on variable importance for the projection, VIP) between the deteriorated and non-deteriorated silages. Next, the key compounds were identified by combining the conditions of average ROAV (aROAV) ≥ 1 and VIP > 1. Finally, the OPLS algorithm was used to analyze the intrinsic link of key compounds with the silage odor. The results showed that three out of 63 compounds—4-ethyl phenol, eugenol, and ethyl linoleate—were key compounds to characterize whether the silages deteriorated or not. In addition, ortho-guaiacol, 4-ethyl guaiacol, and 2-methoxy-4-vinyl phenol were the specific key compounds for deteriorated silage. Eugenol and ethyl linoleate were correlated with fruity, sour, and spicy odors. In addition, guaiacol, 4-ethylphenol, 4-ethyl guaiacol and 2-methoxy-4-vinyl phenol contributed to roasted, musty, and putrid odors.

Although non-invasive prenatal testing (NIPT) is widely used to detect fetal abnormalities, the results of NIPT vary by population, and data for the screening efficiency of NIPT positive predictive value (PPV) from different populations is limited. Herein, we retrospectively analyzed the NIPT results in a large multicenter study involving 52,855 pregnant women. Depending on gestational age, amniotic fluid or umbilical cord blood was extracted for karyotype and/or chromosome microarray analysis (CMA) in NIPT-positive patients, and the PPV and follow-up data were evaluated to determine its clinical value. Among the 52,855 cases, 754 were NIPT-positive, with a positivity rate of 1.4%. Karyotype analysis and/or CMA confirmed 323 chromosomal abnormalities, with a PPV of 45.1%. PPV for trisomy 21 (T21), trisomy 18 (T18), trisomy 13 (T13), sex chromosomal aneuploidies (SCAs), and copy number variations (CNVs) were 78.9, 35.3, 22.2, 36.9, and 32.9%, respectively. The PPVs for T21, T18, and T13 increased with age, whereas the PPVs for SCAs and CNVs had little correlation with age. The PPV was significantly higher in patients with advanced age and abnormal ultrasound. The NIPT results are affected by population characteristics. NIPT had a high PPV for T21 and a low PPV for T13 and T18, and screening for SCAs and CNVs showed clinical significance in southern China. noninvasive non invasive (NIPT abnormalities (PPV limited Herein 52855 52 855 52,85 women andor (CMA NIPTpositive followup follow up cases 75 NIPTpositive, positive, 14 1 4 1.4% 32 451 45 45.1% 2 T , (T21) T18 (T18) T13, (T13) SCAs, (SCAs) (CNVs 789 78 9 78.9 353 35 3 35.3 222 22 22.2 369 36 36.9 329 32.9% respectively T1 ultrasound characteristics T2 China 5285 5 85 52,8 7 1.4 45.1 (T21 (T18 (T13 (SCAs 78. 35. 22. 36. 32.9 528 8 52, 1. 45.

Abstract This work studied the effects of different time and temperature combinations [100 °C for 50 min (T1), 110 °C for 50 min (T2), 118 °C for 50 min (T3) and 121 °C for 30 min (T4)] of sterilization on the sensory quality and lipid oxidation of Dezhou braised chicken. Compared to T1, T3 and T4 groups, the T2 group had the highest colour and lower hardness. The principal component analysis (PCA) of the electronic-tongue results showed that there were distinct differences in taste between the treatment groups. Free amino acids (FAA) analysis showed that the T2 group had the highest amino acid contents. In summary, the T2 might be a more reasonable sterilization condition for Dezhou braised chicken, due to its positive effects on maintaining sensory quality. The results of this study could guide Dezhou braised chicken industry to produce better quality products. 100 [10 C 5 T1 T , (T1) 11 T2, (T2) (T3 12 3 (T4) groups hardness PCA (PCA electronictongue electronic tongue FAA (FAA contents summary products 10 [1 (T1 1 (T2 (T (T4 [

Abstract Palmitoleic acid (C16:1n7, POA), a 16-carbon ω-7 monounsaturated functional fatty acid, has been demonstrated a variety of beneficial properties to human health and a wide range of applications in nutrition, medical and chemical industries. Lipozyme® RM IM (Rhizomucor Miehei lipase), a Sn-1,3 specific lipase, was used to catalyze the hydrolysis of seabuckthorn fruit oil and produce monoglycates rich in palmitoleic acid. The fruit oil of seabuckthorn was used as the research object, the dosage of enzyme taking 10% wt.% oil, the influence of water/oil ratio, pH value and reaction temperature to hydrolysis rate were investigated, and then the response surface methodology was applied for optimizing the process conditions. Further, the relationship between the hydrolysis rate and the content of monoacylglycerol was studied under the optimal hydrolysis conditions. The result indicated that the optimal combined condition is as follows: the reaction temperature is 55°C, the pH is 7, the water-oil quality ratio is 1:1. The hydrolysis rate achieved 79.59% within 12 h in the condition above. Under the optimal conditions, the hydrolysis rate was positively correlated with the content of monoester, and the correlation coefficient was 0.999 within the first 10 h of the reaction. The hydrolysis rate was 66.76% at 10 h, and the content of monoglyceride reached the highest of 61.11%. Hereafter, the hydrolysis of monoglyceride began if the reaction continued. The content of palmitoleic acid increased from 27.11% to 40.84%, and that of linoleic acid increased from 4.51% to 33.34%, so the total amount of the two functional fatty acids reached 74.18%. Enzymatic hydrolysis can be an effective way to improve the function of seabuckthorn fruit oil.

RESUMO Objetivos: Investigar a incidência, fatores de risco e desfechos visuais do desenvolvimento da membrana epirretiniana após reparo do descolamento regmatogênico da retina. Métodos: Trata-se de um estudo retrospectivo de 309 olhos submetidos à cirurgia inicial para descolamento regmatogênico da retina primário sem complicações. Os exames foram realizados no pré-operatório aos 1, 3, 6 e 12 meses pós-operatórios. Os pacientes foram divididos em dois grupos, dependendo da presença ou ausência de membrana epirretiniana. Resultados: A incidência de membrana epirretiniana pós-operatória foi de 28,5%; 42,7% desses pacientes apresentaram desenvolvimento grave da membrana epirretiniana e, portanto, foram submetidos à remoção desta membrana. A regressão logística mostrou que as lágrimas retinianas gigantes (RC: 2,66; 95% IC: 1,045 - 6,792, p=0,040) e lágrimas em ferradura (RC: 0,534; 95% IC: 0,295-0,967, p=0,039), foram preditores significativos de membrana epirretiniana pós-operatória. A coloração com acetonida de triancinolona foi significativamente associada à prevenção da membrana epirretiniana (p=0,022). Trinta e quatro pacientes apresentaram acuidade visual melhorada, ou igual, ou acuidade visual final melhor corrigida; 4 olhos foram avaliados na consulta final de acompanhamento e apresentaram redução da acuidade visual melhor corrigida. Conclusão: Nossa análise demonstra que as lágrimas de ferradura e as lágrimas retinianas gigantes representam fatores de risco para a membrana epirretiniana pós-operatória. A coloração com acetonida de triancinolona teve um efeito preventivo significativo na membrana epirretiniana no pós-operatório. Além disso, uma segunda rodada de vitrectomia pars plana, incluindo remoção da membrana, levou a uma melhora significativa da acuidade visual final melhor corrigida na última consulta de acompanhamento, embora a recuperação tenha sido limitada.

ABSTRACT Purpose: To investigate the incidence, risk factors, and visual outcomes of epiretinal membrane development following rhegmatogenous retinal detachment repair. Methods: This was a retrospective study of 309 eyes that underwent initial surgery for primary uncomplicated rhegmatogenous retinal detachment. Examinations were conducted preoperatively and then postoperatively at 1, 3, 6, and 12 months. The study patients were categorized into two groups depending on the presence or absence of the epiretinal membrane. Results: The incidence of postoperative epiretinal membrane was 28.5%; 42.7% of these patients had severe epiretinal membrane development and therefore underwent the epiretinal membrane removal. Logistic regression analyses revealed that giant retinal tears (OR: 2.66; 95% CI: 1.045-6.792, p=0.040) and horseshoe tears (OR: 0.534; 95% CI: 0.295-0.967, p=0.039) were the significant predictors of postoperative epiretinal membrane. Triamcinolone acetonide staining was significantly associated with the prevention of epiretinal membrane (p=0.022). A total of 34 patients showed a better or an equal final best-corrected visual acuity; of which 4 eyes were evaluated at the final follow-up visit and exhibited a reduced best-corrected visual acuity. Conclusion: Our analysis demonstrated that horseshoe tears and giant retinal tears represent the risk factors for the postoperative epiretinal membrane. Triamcinolone acetonide staining had a significant preventive effect on the postoperative epiretinal membrane. Furthermore, a second round of pars plana vitrectomy, including membrane removal, led to a significant improvement in the final best-corrected visual acuity as per the last follow-up examination, albeit the recovery was limited.

Low Apgar score is associated with increased risk of death in preterm or full-term infants. However, the use of Apgar score to assess extremely preterm (EP) infants is controversial. In this study, we characterized the distribution of Apgar scores in EP infants with gestational age between 25 and 27 weeks, and investigated the association of Apgar score with survival rate at discharge by analyzing the clinical data of the EP infants discharged between January 2008 and December 2017 from 26 neonatal intensive care units in Guangdong Province, China. A total of 1567 infants with gestational age of 26.84±0.79 weeks and birth weight of 951±169 grams were involved in our study. The Apgar score increased with gestational age from 25 to 27 weeks and with time from birth from 1 to 10 min. The survival rate increased with a higher Apgar score, but no significant difference was found for 1-min Apgar score and the survival rate between infants with 25 or 26 weeks of gestation or 5-min Apgar score in infants with 25 weeks of gestation. The Apgar score is associated with survival of EP infants.

Abstract To explore the effect of Multi-Disciplinary Team (MDT) mode in the diagnosis and treatment of Coronavirus Disease 2019 (COVID-19) Pneumonia. A total of 65 patients with suspected COVID-19 pneumonia were included. On February 8, 2020, our hospital officially became a designated hospital for the treatment of COVID-19, and the MDT mode was implemented throughout the diagnosis and treatment for newly admitted patients with suspected COVID-19. The patients were divided into control group and observation group according to whether received MDT mode. Our results showed that the diagnosis time in the observation group was significantly shortened than that in the control group (2.51 days vs. 3.47 days) (p < 0.05). The average daily hospitalization costs in the observation group was significantly decreased in comparison with the control group (¥766.1 vs. ¥1190.4) (p < 0.001). The average daily cost of protective materials in the observation group was significantly reduced in comparison with the control group (¥4226.90 vs. ¥5308.20) (p < 0.001). Compared with the control group, the subjective symptoms of patients in the observation group were significantly improved (p < 0.001). In conclusion, the MDT mode shortens the diagnosis time of, reduces the hospitalization costs, and improves the subjective symptoms of COVID-19.

Abstract The contents of total phenol and flavonoid of 27 edible plants as well as their antioxidative and digestive enzymes inhibitory activities were evaluated. The total phenol content of the 27 plants ranged from 1.28-46.80 mg gallic acid equivalent/g. DPPH, ABTS and reducing power assay explored that Rubus idaeus Linn, Hibiscus sabdariffa Linn. and Crataegus pinnatifida Bge. exhibited stronger antioxidant capacity among the 27 plants. 4 plants showed inhibitory percentage more than 50% on pancreatic lipase. 10 plants showed inhibitory percentage more than 50% on α-glucosidase. 3 plants simultaneously possess significant inhibitory activities on pancreatic lipase and α-glucosidase, which were Alpinia officinarum Hance, Ginkgo biloba Linn. leaves and Vitis vinifera Linn. Seeds. Strong positive correlation between total phenol content and antioxidative capacity were found. However, digestive enzymes inhibitory activity was less correlated with total phenol and total flavonoids content.

ABSTRACT Purpose: To investigate the effect of genistein on inflammation and mitochondrial function of diabetic nephropathy. Methods: Diabetic nephropathy model was established in Sprague-Dawley rats. Automatic biochemical analyzer was employed to detect the kidney function index, serum creatinine, serum urea nitrogen, and 24 h-urine protein and blood glucose. Hematoxylin and eosin staining and periodic acid Schiff staining were used to observe renal morphology. Mitochondrial changes and podocyte integrity were monitored by transmission electron microscope. The expression levels of mfn2, NOX4, P53, MAPK, and NF-κB were detected by Western blotting. The changes of mitochondrial membrane potential were measured by JC-1. The level of mfn2 was assessed by immunofluorescence assay. Results: Genistein ameliorated the kidney function with reduced Scr and blood glucose. The expressions of NOX4, MAPK, p65 and p53 were downregulated, while the expression of mnf2 was the opposite in genistein-treated kidneys. Further investigations revealed that genistein reduced expansion of mesangial matrix and oxidative stress, protected podocyte integrity and increased mitochondrial membrane potential. Conclusions: Genistein could alleviate diabetic nephropathy through inhibiting MAPK/NF-κB pathway, improving mitochondrial function and anti-inflammatory.

Abstract: Social commerce is an emerging platform that entails different social features to attract the attention of online consumers. Borrowing insights from the psychological contract theory, this study examines the characteristics of social commerce platforms, such as platform interactivity and rating and reviews that influence the consumers’ purchase intentions. An online survey of 430 consumers was conducted on a popular social commerce site in China. Partial least squares structural equation modeling and fuzzy sets qualitative comparative analysis techniques are used to analyze this mediation model. The results reveal the positive relationships between (1) psychological contract and purchase intention; (2) platform interactivity and relational contract; and (3) rating and reviews and transactional contract. Besides, partial mediating effects of relational contract, on the relationship between platform interactivity and purchase intention, and transactional contract, on the relationship between rating and reviews and purchase intention, are also observed. Moreover, fuzzy sets qualitative comparative analysis validates the robustness of platform characteristics with psychological contracts and purchase intentions. Overall findings suggest that the platform characteristics have the potential to transform consumers’ purchase intentions through psychological contracts. The study provides new insights on consumers' behavior in social commerce milieus, along with its theoretical and practical implications.

Abstract Klotho is originally discovered as an anti-aging gene and knock-out of klotho accelerates aging in mice. Subsequent studies support the anti-carcinogenesis role of klotho in a variety of human malignancies. The present study investigated the role of klotho on growth and metastasis of osteosarcoma cells. The osteosarcoma cells were transduced with lentivirus particles encoding klotho or scramble control. The reconstructed osteosarcoma cells were injected into the femoral medullary cavity of nude mice to establish a xenograft animal model. The anti-tumor properties of klotho were evaluated in terms of tumor growth, apoptosis, glycogen production, and pulmonary metastasis. Lentivirus-mediated overexpression of klotho significantly decreased tumor volume and weight in osteosarcoma mice. Determination of PCNA and Ki67 expression revealed that overexpression of klotho inhibited cell proliferation in tumor tissues obtained from osteosarcoma xenografts. PAS staining also showed that overexpression of klotho significantly decreased the production of glycogen in osteosarcoma. Moreover, TUNEL positive cells were significantly increased after lentivirus-mediated overexpression of klotho. Furthermore, lentivirus-mediated upregulation of klotho reduced the number of pulmonary metastatic lesions in mice compared to control mice. These findings demonstrated that elevated klotho could inhibit osteosarcoma cell growth and pulmonary metastasis in vivo, suggesting that klotho may be a valuable therapeutic target for osteosarcoma.

Resumo Fundamento: Na observação clínica, os pacientes com síndrome coronariana aguda com doença arterial periférica têm prognóstico ruim, portanto, a relação entre as doenças e as características clínicas precisa ser mais explorada. Objetivos: Este estudo tem o objetivo de investigar características clínicas e fatores de risco independentes para eventos adversos hospitalares em pacientes com síndrome coronariana aguda e história de doença arterial periférica (DAP). Métodos: Foram incluídos no estudo 5682 pacientes com síndrome coronariana aguda. Os pacientes foram divididos em dois grupos de acordo com a presença ou ausência de DAP prévia: grupo DAP (n = 188) e grupo sem DAP (n = 5494, grupo controle). Em seguida, foram analisadas características clínicas e a incidência de eventos adversos hospitalares nesses grupos; um p < 0,05 foi considerado estatisticamente significativo. Resultados: A idade dos pacientes com DAP foi maior que a idade do grupo controle (65,5 ± 10,3 anos vs. 58,6 ± 11 anos, p < 0,001), e a proporção de pacientes com história de diabetes ou acidente vascular cerebral foi maior no grupo DAP que no grupo controle [73 (39%) vs. 1472 (26,8%), p = 0,018; 36 (19,3%) vs. 396 (7,2%), p < 0,001). A análise de regressão logística multivariada para eventos adversos hospitalares mostrou que história de DAP (OR = 1,791, p = 0,01), história de diabetes (OR = 1,223, p = 0,001), e idade >65 anos de idade (OR = 4,670, p < 0,001) foram fatores de risco independentes para eventos adversos hospitalares. Conclusão: DAP prévia, idade avançada, e história de diabetes são fatores de risco independentes para eventos adversos hospitalares em pacientes com síndrome coronariana aguda.

Abstract Background: In clinical observation, patients with acute coronary syndrome complicated with peripheral artery disease have poor prognosis, so the relationship between the diseases and clinical characteristics need to be further explored. Objective: This study aims to investigate clinical characteristics and independent risk factors for in-hospital adverse events in acute coronary syndrome patients with a history of peripheral arterial disease (PAD). Methods: A total of 5,682 patients with acute coronary syndrome were included into this study. These patients were divided into two groups according to the presence or absence of a history of PAD: PAD group (n = 188), and non-PAD (control) group (n = 5,494). Then, the clinical characteristics and incidence of in-hospital adverse events were analyzed; p < 0.05 was considered statistically significant. Results: The age of PAD patients was higher than that in the control group (65.5 ± 10.3 years vs. 58.6 ± 11 years, p < 0.001), and the proportion of PAD patients with diabetes history and stroke history was higher than that in the control group (73 [39%] vs. 1472 [26.8%], p = 0.018; 36 [19.3%] vs. 396 [7.2%], p < 0.001). The multivariate logistic regression analysis between groups based on in-hospital adverse events revealed that a history of PAD (OR = 1.791, p = 0.01), a history of diabetes (OR = 1.223, p = 0.001), and age of > 65 years old (OR = 4.670, p < 0.001) were independent risk factors for in-hospital adverse events. Conclusion: A history of PAD, advanced age, and a history of diabetes are independent risk factors for in-hospital adverse events in patients with acute coronary syndrome.

Abstract: Background: Facial threading involves the removal of hairs to restore facial skin smoothness. However, its effectiveness has not been rigorously evaluated. Objective: To evaluate effects of facial threading on skin roughness, hydration, melanin index, and vellus hair on the face, complemented by a subjective evaluation of the tactile feel of the skin and improvement in skin color. Method: Participants who had not used exfoliators for two weeks before the experiment were included. Each participant underwent one session of facial threading every 21 days, for a total of 3 sessions. A three-dimensional skin roughness instrument and a multifunctional skin testing system were used to evaluate changes in roughness, hydration, and pigmentation on the forehead, cheeks, and corners of the mouth. A photomicrographic camera was used to record changes in vellus hair. Subjective reports of skin smoothness and color were recorded. Result: Eighteen participants completed the study. Facial threading produced a significant decrease in skin roughness on the forehead (22.42%, p = .013), right cheek (77%, p = .02), and left corner of the mouth (33.02%, p = .001). Subjective improvement in tactile feel of the skin and coloring were reported. Study Limitations: The study did not include randomization, with further limitations of a small sample size and a single site. Conclusion: Facial threading reduced skin roughness by 26.74% after three threading sessions, with improved subjective assessment of tactile feel and coloring. Future research should include a comparison with other cosmetic products with similar beautifying effects or a control group.

Abstract The leaves of Syringa oblata Lindl., Oleaceae, had been extensively used as a folk medicine to treat various infections, heal inflammations, icteric hepatitis and acute mastitis. The study was designed to evaluate the hepatoprotective activity of S. oblata leaves ethanol extract against CCl4-induced hepatotoxicity in primary hepatocytes and mice with the indicator of glutathione S-transferase alpha 1. The hepatoprotective effects of S. oblata leaves ethanol extract were evaluated on the basis of liver histopathology and biochemical parameters as well as hepatic oxidative stress markers. The results showed that CCl4 negatively modulated biochemical parameters and liver antioxidant activities. However, the use of S. oblata leaves ethanol extract restored altered-serum biochemical parameters and liver antioxidant activities in a dose-dependent manner. Importantly, the trends in S-transferase alpha 1 were similar to alanine aminotransferase and aspartate aminotransferase level, and S-transferase alpha 1 was suggested to be a marker for the evaluation of hepatoprotective activity of S. oblata leaves ethanol extract. Histopathological examination showed that CCl4 causes significant hepatic injury relative to control group. The above findings suggested that S. oblata leaves ethanol extract has hepatoprotective effects against CCl4-induced hepatic injury and S-transferase alpha 1 may be an indicator to evaluate the protective effects of S. oblata leaves ethanol extract.
