Abstract Objective: To investigate the optimal timing of initial intravenous immunoglobulin (IVIG) treatment in Kawasaki disease (KD) patients. Methods: KD patients were classified as the early group (day 1-4), conventional group (day 5-7), conventional group (day 8-10), and late group (after day 10). Differences among the groups were analyzed by ANOVA and Chi-square analysis. Predictors of IVIG resistance and the optimal cut-off value were determined by multiple logistic regression analyses and receiver operating characteristic (ROC) curve analysis. Results: There were no significant differences in IVIG resistance among the 4 groups (p = 0.335). The sensitivity analysis also confirmed no difference in the IVIG resistance between those who started the initial IVIG ≤ day 7 of illness and those who received IVIG >day 7 of illness (p = 0.761). In addition, patients who received IVIG administration more than 7 days from the onset had a higher proportion of coronary artery abnormalities (p = 0.034) and longer length of hospitalization (p = 0.033) than those who started IVIG administration less than 7 days. The optimal cut-off value of initial IVIG administration time for predicting IVIG resistance was >7 days, with a sensitivity of 75.25% and specificity of 82.41%. Conclusions: IVIG therapy within 7 days of illness is found to be more effective for reducing the risk of coronary artery abnormalities than those who received IVIG >day 7 of illness. IVIG treatment within the 7 days of illness seems to be the optimal therapeutic window of IVIG. However, further prospective studies with long-term follow-up are required.

Abstract Objectives: Abdominal Aortic Aneurysm (AAA) is a complex disease with both genetic and environmental risk factors. This study aimed to examine the potential association of the +276G/T and −420C>G polymorphisms in the resistin gene with AAA susceptibility and progression. Method: We performed a retrospective study involving AAA patients and healthy controls, assessing the distribution of the +276G/T and −420C>G genotypes in both groups. Hardy-Weinberg equilibrium was assessed for both polymorphisms. Logistic regression was used to explore the influence of these genotypes on AAA occurrence and progression, adjusting for relevant confounders. Results: The distribution of +276G/T polymorphism did not significantly differ between AAA patients and controls. Conversely, a significant difference was observed in the genotype distribution of −420C>G polymorphism between the two groups. The CC genotype and CC/CG genotypes of −420C>G polymorphism were found to be associated with an increased risk and progression of AAA. Conclusions: The −420C>G polymorphism, particularly the CC genotype and CC/CG genotypes, might play a substantial role in AAA susceptibility and progression. The present findings underscore the need for further investigations to confirm these associations and fully elucidate the role of the resistin gene in AAA.

Abstract A reinforced concrete (RC) column improved with central large-diameter butted steel rods (CLBSR column) has been proposed to increase the limit value of the axial compression ratio. This paper presents the seismic behavior analysis of CLBSR columns subjected to low-cycle reciprocating loading. The CLBSR columns were also compared with the RC column improved with central large-diameter steel rods (CLSR column) and the RC column improved with central reinforcement bars (CRB column) under the same experimental conditions. The typical failure modes, hysteretic curves, skeleton curves, stiffness degradation, and energy dissipation capacity were all investigated. The improved PARK damage model obtained the corresponding relationships between the damage indices and the damage state of each column. The test results indicated that the CLBSR columns and CLSR columns had similar seismic behavior, but were slightly inferior to the CRB columns. Overall, the butt joint of large-diameter steel rods had little effect on the seismic behavior.

Abstract Astragaloside IV (AS-IV) has been shown to possess cardioprotective effect. However, the specific mechanism of AS-IV in myocardial infarction (MI) remains unclear. Our results showed that AS-IV intervention observably enhanced cell viability and reduced cell apoptosis, oxidative stress levels and inflammatory factor secretion. Expression of MIRT1 was significantly up-regulated in hypoxia-treated cells. In addition, ALCAM overexpression reversed the effects of AS-IV intervention on hypoxia-treated cell functions. MIRT1 facilitated Runx3 promoter methylation and its downregulated expression by recruiting DNA methyltransferase 3B (DNMT3B) to the Runx3 promoter region through binding with suppressor of Zeste 12 protein homolog (Suz12). Runx3 silencing reversed the effects of MIRT1 inhibition on hypoxia-treated cell functions. Betulinic acid suppressed the effects of AS-IV intervention on the behaviors of hypoxia-treated cells. AS-IV treatment improved the cardiac functions of mice with MI. Taken together, these findings demonstrated that AS-IV treatment inhibits DNMT3B-mediated Runx3 promoter methylation by restraining Suz12 expression and further blocks the NF-κB signaling pathway, and in turn improves the cardiac functions of mice with MI.

Abstract In this study, lotus root polysaccharide was taken as raw material. The preparation technology of its polysaccharide selenium was established by response surface design, and its antioxidant activity in vitro was studied. Selenium content was taken as the detection index, and the effects of reaction time, the ratio of sodium selenite to the polysaccharide, and the volume fraction of nitric acid on selenium content were investigated. Through the response surface method, the optimal synthesis conditions of lotus root polysaccharide selenium were obtained as follows: reaction time of 5.36h, the ratio of sodium selenite and lotus root polysaccharide is 0.78, the volume fraction of nitric acid 0.47%, the selenium content of lotus root polysaccharide selenium 0.1106%. Selenium, a polysaccharide from lotus root, had a scavenging effect on ABTS radical and superoxide ion, and the maximum scavenging rate was 52.17% and 85.23%, respectively. Aa shows that the synthesized lotus root polysaccharide selenium can be used as an antioxidant or functional food.

Abstract Background: The internal NAD(P)H dehydrogenase (NDA) gene family was a member of the NAD(P)H dehydrogenase (ND) gene family, mainly involved in the non-phosphorylated respiratory pathways in mitochondria and played crucial roles in response to abiotic stress. Methods: The whole genome identification, structure analysis and expression pattern of NDA gene family were conducted to analyze the NDA gene family. Results: There were 51, 52, 26, and 24 NDA genes identified in G. hirsutum, G. barbadense, G. arboreum and G. raimondii, respectively. According to the structural characteristics of genes and traits of phylogenetic tree, we divided the NDA gene family into 8 clades. Gene structure analysis showed that the NDA gene family was relatively conservative. The four Gossypium species had good collinearity, and segmental duplication played an important role in the evolution of the NDA gene family. Analysis of cis-elements showed that most GhNDA genes contained cis-elements related to light response and plant hormones (ABA, MeJA and GA). The analysis of the expression patterns of GhNDA genes under different alkaline stress showed that GhNDA genes were actively involved in the response to alkaline stress, possibly through different molecular mechanisms. By analyzing the existing RNA-Seq data after alkaline stress, it was found that an NDA family gene GhNDA32 was expressed, and then theGhNDA32 was silenced by virus-induced gene silencing (VIGS). By observing the phenotype, we found that the wilting degree of silenced plants was much higher than that of the control plant after alkaline treatment, suggesting that GhNDA32 gene was involved in the response to alkaline stress. Conclusions: In this study, GhNDAs participated in response to alkaline stress, especially NaHCO3 stress. It was of great significance for the future research on the molecular mechanism of NDA gene family in responding to abiotic stresses.

Abstract Present study aims to establish a reliable infant digestion model using pH-STAT method and the model is also applied to static in-vitro digestion of different infant formulas. Model-3 which consisted of NaCl, KCl and CaCl2 as gastrointestinal digestive fluids demonstrated better repeatability than model-1 was selected for the evaluation of static in-vitro digestion of different infant formulas (different fatty acids, protein composition and with/without milk fat globule membrane) using pH-STAT method. Three infant formulas (IF) with different fatty acids composition were evaluated and IF2 which contained the highest amounts of medium-chain saturated fatty acids (8.02 ± 0.47%) demonstrated the highest in-vitro gastrointestinal lipolysis rate (65.88 ± 0.24%). Infant formulas containing peptides and amino acids were more easily hydrolyzed by protease, which probably enhanced the release of FFA (IF1, 50.60 ± 0.87%; IF4, 60.17 ± 2.97%; IF5, 62.21 ± 2.27%; IF6, 66.51 ± 2.38%). In addition, the presence of milk fat globule membrane (MFGM, IF7) was found to accelerate in-vitro gastrointestinal lipolysis (IF1, 50.60 ± 0.87%; IF7, 58.05 ± 1.77%). In summary, the new developed model is suitable for investigating in-vitro digestion of different infant formulas.

Abstract The occurrence of zearalenone is considered a major risk factor affecting human and animal health worldwide. Zearalenone-contaminated feed can cause serious disorders and diseases in farm animals. A number of approaches have been developed to counteract zearalenone, but only few can be used. A potential approach to protecting animals against the harmful effects of zearalenone-contaminated feed is the use of substances to reduce zearalenone contamination of feed. The present study aimed to evaluate the effect of different absorbents in zearalenone-contaminated feed via in vitro bionic digestion. The results revealed that three types of absorbents exhibit improved effects. More than 50% of zearalenone is absorbed during digestion. Specifically, KLX (the main component is yeast cell wall), absorbed 83% of the zearalenone in the contaminated feed after bionic digestion in vitro. Monogastric animal bionic digestion is a rapid and physiologically relevant method to evaluate the efficacy of adsorbent materials in binding mycotoxins. The technique can be used to pre-screen the mycotoxin/adsorbent combinations as an alternative to animal experiments.

Preeclampsia is a major reason of morbidity and mortality in pregnant women and perinatal fetus. Hence, it is of prime importance that diagnostic markers are defined to predict chances of preeclampsia in pregnant women. It has been previously shown that microRNA (miRNA)-376c expression is decreased in the placenta of preeclampsia patients at term. Even though this decrease was not mimicked in the placenta at the pre-term stage, miR-376c expression was decreased in the plasma of these patients as early as the second trimester. Plasma and placenta specimens were obtained from pregnant women having unifetal gestation undergoing perinatal care between January 2014 and December 2016 (n=49). Early trimester placentas were collected from patients undergoing terminated pregnancies through dilation and curettage procedure. Our results showed that in addition to miR-376c, miR-441 levels were decreased in the placenta of preeclampsia patients, and this decrease occurred both at pre-term and at term. This decrease is also mimicked in the plasma levels at both early and late weeks of pregnancy, highlighting that miR-441 levels can serve as a diagnostic marker of risk of preeclampsia in pregnant women. Overexpression of the miR-441, as well as miR-376c, promoted cell viability, migration, and invasion in the human immortalized cytotrophoblast cell line HTR8/SVneo, indicating that their decrease in pregnant women would result in anomalous apoptosis and functional imbalance resulting in premature abortion and other complications. MiR-441 level can thus potentially serve as diagnostic marker of preeclampsia in pregnant women.

Abstract Purpose: To investigate the effect of mesenteric lymph drainage on the spleen injury and the expressions of inflammatory cytokines in splenic tissue in mice following hemorrhagic shock. Methods: Male C57 mice were randomly divided into the sham shock, shock and shock+drainage groups. The mice in both shock and shock+drainage groups suffered femoral artery bleeding, maintained mean arterial pressure (MAP) of 40±2 mmHg for 90 min, and were resuscitated. And mesenteric lymph drainage was performed in the shock+drainage group at the time of resuscitation. After three hours of resuscitation, the splenic tissues were harvested for the histological observation and protein and mRNA expression analysis of cytokines. Results: The spleen in the shock group revealed a significantly structural damage and increased mRNA expressions of MyD88 and TRAF6 and protein expressions of TIPE2, MyD88, TRIF and TRAF3 compared to the sham group. By contrast, the splenic pathological injury in the shock+drainage group was alleviated significantly, and the mRNA and protein expressions of TIPE2, MyD88, TRIF, TRAF3 and TRAF6 were significantly lower than those in the shock group. Conclusion: These results indicate that post-hemorrhagic shock mesenteric lymph drainage alleviates hemorrhagic shock-induced spleen injury and the expressions of inflammatory cytokines.

This is a case report of lichen planus (LP) with multiple system involvement. A 35-year-old female patient was admitted in November 2014 with a 5-year history of painful/difficult sexual intercourse and loss of oral mucosa, and an 8-year history of focal hair loss. Earlier, the patient had been unable to adhere to corticosteroid therapy because of severe adverse side effects. In September 2014, labia minora mucosa defects and stricture of the urethral orifice (with dysuria), vaginal orifice, and vagina were identified. Biopsy was performed and a diagnosis of erosive LP was made. The patient was treated with an oral immunosuppressant (cyclosporine A) and urethral/vaginal dilatation. Urine flow rate and sex life were improved after 6 months and she discontinued medication. Four years later, the patient reported a good overall treatment efficacy. LP can involve multiple systems and should be considered in patients with dyspareunia. Immunosuppressive agents can achieve a satisfactory effect in patients with contraindication to corticosteroid.

Abstract This study aimed to investigate the cardioprotection of rosuvastatin pre-conditioning (R-Pre) in a rat model of myocardial ischemia / reperfusion (I/R). Male SD rats were assigned into three groups: sham group, I/R group and R-Pre group. Rats in I/R group and R-Pre group received ischemia for 30 min and reperfusion for 2 h. In R-Pre group, rats received intragastrical administration with rosuvastatin at 5 mg/kg once daily for 1 week. After 2-h reperfusion, the cardiac function was detected by ultrasonography; the blood was collected for biochemical analysis; the heart was collected for the TUNEL staining and immunohistochemistry for Bcl-2 and Bax. Our results showed rosuvastatin pre-conditioning for 1 week could significantly reduce the infarct ratio and improve the cardiac function after myocardial I/R injury, in which attenuation of oxidative stress and cell apoptosis played an important role. Our study provides evidence on the cardioprotection of rosuvastatin pre-conditioning and highlight the use of rosuvastatin before cardiopulmonary bypass.

Abstract Objective This study aimed to determine the differences in learning style preferences among bachelor degree nursing students at Central South University and associate degree nursing students at the Vocational Health School in China. Methods This study was a cross-sectional survey using the Chinese version of the VARK questionnaire to assess preferred learning styles: 159 enrolled bachelor degree nursing students and 199 enrolled associate degree nursing students completed the questionnaire with a response rate of 96.8%. Results The bachelor degree nursing students tend to prefer a multimodal learning style (58.49%), which significantly differed from that of associate degree nursing students (45.77%). The kinaesthetic modality was the predominant unimodal learning style among the bachelor degree and associate degree nursing students (18.20% and 33.67%), and the read-write modality was the least popular modality (2.5% and 4.02%). Conclusion There are both differences and similarities between the learning style preferences of bachelor degree and associate degree nursing students. Educational background is one of the most critical factors that influence the learning style preference of nursing students. This finding may be necessary and beneficial for carrying out future curricula reform. In addition, further comprehensive research should be conducted to examine the relationships between learning style preferences and academic performance, as well as learning style preferences and teaching methods.
