ABSTRACT Objective: The optimal target for blood glucose concentration in critically ill patients is unclear. We will perform a systematic review and meta-analysis with aggregated and individual patient data from randomized controlled trials, comparing intensive glucose control with liberal glucose control in critically ill adults. Data sources: MEDLINE®, Embase, the Cochrane Central Register of Clinical Trials, and clinical trials registries (World Health Organization, clinical trials.gov). The authors of eligible trials will be invited to provide individual patient data. Published trial-level data from eligible trials that are not at high risk of bias will be included in an aggregated data meta-analysis if individual patient data are not available. Methods: Inclusion criteria: randomized controlled trials that recruited adult patients, targeting a blood glucose of ≤ 120mg/dL (≤ 6.6mmol/L) compared to a higher blood glucose concentration target using intravenous insulin in both groups. Excluded studies: those with an upper limit blood glucose target in the intervention group of > 120mg/dL (> 6.6mmol/L), or where intensive glucose control was only performed in the intraoperative period, and those where loss to follow-up exceeded 10% by hospital discharge. Primary endpoint: In-hospital mortality during index hospital admission. Secondary endpoints: mortality and survival at other timepoints, duration of invasive mechanical ventilation, vasoactive agents, and renal replacement therapy. A random effect Bayesian meta-analysis and hierarchical Bayesian models for individual patient data will be used. Discussion: This systematic review with aggregate and individual patient data will address the clinical question, ‘what is the best blood glucose target for critically ill patients overall?’ Protocol version 0.4 - 06/26/2023 PROSPERO registration: CRD42021278869

Abstract Objective To explore whether Cyclic Adenosine Monophosphate (cAMP)-Epac1 signaling is activated in 1-Desamino-8-D-arginine-Vasopressin-induced Endolymphatic Hydrops (DDAVP-induced EH) and to provide new insight for further in-depth study of DDAVP-induced EH. Methods Eighteen healthy, red-eyed guinea pigs (36 ears) weighing 200-350 g were randomly divided into three groups: the control group, which received intraperitoneal injection of sterile saline (same volume as that in the other two groups) for 7 consecutive days; the DDAVP-7d group, which received intraperitoneal injection of 10 mg/mL/kg DDAVP for 7 consecutive days; and the DDAVP-14d group, which received intraperitoneal injection of 10 μg/mL/kg DDAVP for 14 consecutive days. After successful modeling, all animals were sacrificed, and cochlea tissues were collected to detect the mRNA and protein expression of the exchange protein directly activated by cAMP-1 and 2 (Epac1, Epac2), and Repressor Activator Protein-1 (Rap1) by Reverse Transcription (RT)-PCR and western blotting, respectively. Results Compared to the control group, the relative mRNA expression of Epac1, Epac2, Rap1A, and Rap1B in the cochlea tissue of the DDAVP-7d group was significantly higher (p< 0.05), while no significant difference in Rap1 GTPase activating protein (Rap1gap) mRNA expression was found between the two groups. The relative mRNA expression of Epac1, Rap1A, Rap1B, and Rap1gap in the cochlea tissue of the DDAVP-14d group was significantly higher than that of the control group (p< 0.05), while no significant difference in Epac2 mRNA expression was found between the DDAVP-14d and control groups. Comparison between the DDAVP-14d and DDAVP-7d groups showed that the DDAVP-14d group had significantly lower Epac2 and Rap1A (p< 0.05) and higher Rap1gap (p < 0.05) mRNA expression in the cochlea tissue than that of the DDAVP-7d group, while no significant differences in Epac1 and Rap1B mRNA expression were found between the two groups. Western blotting showed that Epac1 protein expression in the cochlea tissue was the highest in the DDAVP-14d group, followed by that in the DDAVP-7d group, and was the lowest in the control group, showing significant differences between groups (p< 0.05); Rap1 protein expression in the cochlea tissue was the highest in the DDAVP-7d group, followed by the DDAVP-14d group, and was the lowest in the control group, showing significant differences between groups (p< 0.05); no significant differences in Epac2 protein expression in the cochlea tissue were found among the three groups. Conclusion DDAVP upregulated Epac1 protein expression in the guinea pig cochlea, leading to activation of the inner ear cAMP-Epac1 signaling pathway. This may be an important mechanism by which DDAVP regulates endolymphatic metabolism to induce EH and affect inner ear function.

Abstract Background Migraine underdiagnosis and undertreatment are so widespread, that hence is essential to diagnose migraine sufferers in nonclinical settings. A systematic review of validation studies on migraine diagnostic tools applicable to nonclinical settings can help researchers and practitioners in tool selection decisions. Objective To systematically review and critically assess published validation studies on migraine diagnostic tools for use in nonclinical settings, as well as to describe their diagnostic performance. Methods A multidisciplinary workgroup followed transparent and systematic procedures to collaborate on this work. PubMed, Medline, and Web of Science were searched for studies up to January 17, 2022. The QUADAS-2 was employed to assess methodological quality, and the quality thresholds adopted by the Global Burden Disease study were used to tail signaling questions. Results From 7,214 articles identified, a total of 27 studies examining 19 tools were eligible for inclusion. There has been no high-quality evidence to support any tool for use of migraine diagnosis in nonclinical settings. The diagnostic accuracy of the ID-migraine, structured headache and HARDSHIP questionnaires have been supported by moderate-quality evidence, with sensitivity and specificity above 70%. Of them, the HARDSHIP questionnaire has been the most extensively validated. The remaining 16 tools have provided poor-quality evidence for migraine diagnosis in nonclinical populations. Conclusions Up till now, the HARDSHIP questionnaire is the optimal choice for diagnosing migraine in nonclinical settings, with satisfactory diagnostic accuracy supported by moderate methodological quality. This work reveals the crucial next step, which is further high-quality validation studies in diverse nonclinical population groups.

ABSTRACT Purpose: Oxidative stress and apoptosis contribute to the pathological basis of doxorubicin (DOX)-induced cardiotoxicity. Columbianadin (CBN) is one of the main bioactive constituents isolated from the root of Angelica pubescens. Herein, we intended to explore the potential role and molecular basis of CBN in DOX-induced cardiotoxicity. Methods: C57BL/6 mice were subjected to DOX (15 mg/kg/day, i.p.) to generate DOX-induced cardiotoxicity. CBN (10 mg/kg/day, i.p.) was administered for four week following DOX injection. Results: DOX administered markedly dampened cardiac function, increased cardiac injury, excessive reactive oxygen species (ROS) production, and cardiomyocyte loss. These alterations induced by DOX significantly alleviated by CBN treatment. Mechanistically, our results demonstrated that the CBN exerts cardioprotection role against DOX by up-regulating silent information regulator 1 (Sirt1) and decreasing acetylation of forkhead box O1 (FOXO1). Moreover, Sirt1 inhibition with Ex-527 significantly blunt the beneficial effect of CBN on DOX-induced cardiotoxicity, including cardiac dysfunction, ROS, and apoptosis. Conclusion: Collectively, CBN attenuated oxidative stress and cardiomyocyte apoptosis in DOX-induced cardiotoxicity through maintaining Sirt1/FOXO1 signaling pathway. Our results demonstrated that CBN might be used to treat DOX-related cardiotoxicity.

RESUMEN Varios lagos se formaron en el área donde convergen el río Huai y el Gran Canal durante el período histórico, lo que juega un rol importante en la evolución del entorno regional. El lago Gaoyou es un importante reservorio en los segmentos bajos del río Huai. En este trabajo se analizaron las variaciones en hidrología y los cambios ambientales de la cuenca amplia con base en los grupos de polen, tamaño del grano y litología de las muestras de sedimento recolectadas en el lago Gaoyou. Este trabajo se enfoca en las variaciones de los procesos hidrodinámicos del lago Gaoyou que fueron las respuestas a los cambios del clima, los eventos hidrológicos regionales, y la actividad humana. Los altos porcentajes de polen de las hierbas terrestres y los resultados de los análisis de componentes principales sugieren que el ambiente de la China oriental fue árido entre los años 900 a 1300 DC y esto se corresponde con las condiciones de sequía del Período Cálido Medieval. El período subsecuente entre 1300 y 1650 fue más húmedo, como se revela por un incremento en el polen acuático y en el decrecimiento del tamaño del grano. Un incremento en el taxón de las hierbas xerófitas (especialmente Artemisias y Chenopodioideaes) indica que el clima se tornó arido de nuevo entre 1650 y 1850, durante la Pequeña Edad de Hielo. El período moderno (de 1850 en adelante) se caracterizó por otro incremento en la húmedad, como se refleja en un decrecimiento del polen de hierbas y en los tamaños del grano. Los cambios en el curso del Río Amarillo entre 1194 y 1855 se registran por las variaciones abruptas en la litología, las características de los sedimentos y los porcentajes en los taxones de polen alienígena. Los impactos humanos intensos se demuestran con la ocurrencia de polen tipo cereal y un incremento en el polen de otras plantas cultivadas como las cruciferas y las poáceas. Este estudio presenta una base para análisis posteriores de los mecanismos dinámicos entre el desarrollo del lago, el cambio climático y los efectos de los mayores cambios de los ríos.

ABSTRACT: Numerous lakes formed in the area where the Huai River and the Grand Canal converged during the historical period, and it played a substantial role in the evolution of the regional environment. Gaoyou Lake is a vital detention reservoir in the lower reaches of the Huai River. Variations in hydrology and basin-wide environmental changes were analyzed based on pollen assemblages, grain size data, and lithology from sediment cores collected at Gaoyou Lake. This study focused on variations in the hydrodynamic processes of Gaoyou Lake that were responses to changes in climate, regional hydrological events, and human activity. The high percentages of pollen from terrestrial herbs and results of principal component analysis suggested that the environment of eastern China was arid from AD 900 to 1300 and that this corresponded to the dry conditions of the Medieval Climate Anomaly. The subsequent period between AD 1300 and 1650 was more humid, as revealed by an increase in aquatic pollen and a decrease in grain size. A rise in xerophytic herb taxa (particularly Artemisia and Chenopodioideae) indicated that the climate became arid again from AD 1650 to 1850, during the Little Ice Age. The modern period (AD 1850 onwards) was characterized by another increase in moisture, as reflected by a decrease in herb pollen and grain sizes. The shifts in the course of the Yellow River in AD 1194 and AD 1855 were recorded by abrupt changes in lithology, sediment characteristics, and the percentages of alien pollen taxa. Intense human impacts were demonstrated by cereal-type pollen and an increase in pollen of other cultivated plants such as Cruciferae and Poaceae. This study provides a foundation for further analysis of the dynamic mechanisms between lake development, climate change, and the effects of significant river changes.

Abstract Basic leucine zipper (bZIP) is a conserved transcription factor (TF) widely present in eukaryotes, and it plays an important role in regulating plant growth and stress responses. To better understand the white pear bZIP gene family, comprehensive bioinformatics analysis of the pear genome was performed. A total of 84 PbbZIP genes were identified, which were divided into 13 subfamilies by phylogenetic analysis. The 84 PbbZIP genes were all located in the nucleus, and 77 of those genes were unevenly distributed across the 17 chromosomes of white pear. The other 7 PbbZIP genes were located on the scaffold. Subsequent expression profile analysis showed that PbbZIP genes in exocarp were significantly upregulated or downregulated in ‘Huangguan’ pear with brown spot (BS) compared with healthy pear and in response to hormonal treatment with gibberellin A3 (GA3). These results provide helpful insights into the characteristics of PbbZIP genes and their responses to BS in ‘Huangguan’ pear.

Abstract Background This paper aims to assess the impact of antibiotic therapy management by clinical pharmacists on rational drug use (RDU) in the perioperative period of patients receiving retinal detachment surgery in China from the perspective of prescription structure. Methods: In this study, a retrospective study was used to compare the differences in the RDU between 233 patients (the experimental group) receiving medical treatment and 210 patients (the control group) without clinical pharmacist intervention. The data were collected with a set of indicators adjusted from the core medication use indicator proposed by the World Health Organization and the International Network of Rational Use of Drugs according to the background of China. Results: There were significant differences in average number of drugs per prescription (19.7 and 20.8, P = 0.001), percentage of drugs on the reimbursable list (98.32% and 72.4%, P = 0.003), and average treatment expenditure per prescription (555.3 yuan and 707 yuan) between the experimental group and the controlled group, while average number of antibiotics per prescription (4.2 and 4.3, P = 0.114), average number of injections per prescription (12.02 to 11.96, P = 0.804) were not changed significantly. Conclusions: More efforts are needed to improve the effectiveness of the antibiotic therapy management by clinical pharmacist on rational drug use, meanwhile the objective of cost-saving should be included in the service pattern of clinical pharmacy services.

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 Lagopsis supina (Steph) IK. Gal. was a traditional Chinese medicinal plant for promoting blood circulation and removing blood stasis (PBCRBS), anti-inflammatory and diuresis with little scientific validation. The aims of this study were first to evaluate the PBCRBS and anti-inflammatory effects of L. supina in a rat model of traumatic blood stasis (TBS). We demonstrated that an ethanolic extract of L. supina (LS, 460 mg/kg/d) possessed significant PBCRBS and remarkable inhibitory effect on inflammation cytokines, which were associated with renovated amount of the injured muscle fibers, alleviate the degree of the damaged tissue edema, decreased the number of inflammatory cells, increased the number of the capillary hyperplasia by hematoxylin and eosin (HE), as well as remarkably down-regulated ( p < 0.05 or p < 0.01) the levels of inflammation cytokines, including TNF-α, IL-6, IL-8, and IL-10 by ELISA. This finding provide a pharmacological basis and partial interpretation for the clinical application of L. supina, which has therapeutic properties for blood stasis syndrome (BSS) and inflammation-related diseases.

In particular, the application of Pickering emulsions stabilized polysaccharide particles in encapsulation and delivery of food bioactive ingredients, fat substitutes, and modulation of lipid digestion, was discussed. Finally, the future prospects of Pickering emulsions stabilized by polysaccharide particles were discussed.

ABSTRACT Purpose: Spontaneous intracerebral hemorrhage (ICH) is a major public health problem with a huge economic burden worldwide. Ulinastatin (UTI), a serine protease inhibitor, has been reported to be anti-inflammatory, immune regulation, and organ protection by reducing reactive oxygen species production, and inflammation. Necroptosis is a programmed cell death mechanism that plays a vital role in neuronal cell death after ICH. However, the neuroprotection of UTI in ICH has not been confirmed, and the potential mechanism is unclear. The present study aimed to investigate the neuroprotection and potential molecular mechanisms of UTI in ICH-induced EBI in a C57BL/6 mouse model. Methods: The neurological score, brain water content, neuroinflammatory cytokine levels, and neuronal damage were evaluated. The anti-inflammation effectiveness of UTI in ICH patients also was evaluated. Results: UTI treatment markedly increased the neurological score, alleviate the brain edema, decreased the inflammatory cytokine TNF-α, interleukin‑1β (IL‑1β), IL‑6, NF‑κB levels, and RIP1/RIP3, which indicated that UTI-mediated inhibition of neuroinflammation, and necroptosis alleviated neuronal damage after ICH. UTI also can decrease the inflammatory cytokine of ICH patients. The neuroprotective capacity of UTI is partly dependent on the MAPK/NF-κB signaling pathway. Conclusions: UTI improves neurological outcomes in mice and reduces neuronal death by protecting against neural neuroinflammation, and necroptosis.

Abstract Polyphenol oxidase (PPO) plays a key role in tea processing. It catalyzes the conversion of tea polyphenols into theaflavin and its derivatives. PPO was partially purified and characterized in both its soluble form (sPPO) and membrane-bound form (mPPO) from tea (Camellia sinensis) leaves. Both forms were purified by three-phase partitioning and membrane ultrafiltration. sPPO and mPPO showed high activity against diphenols as substrate and had the highest affinity for catechol and caffeic acid. The optimum temperatures and pH for enzyme activity were different. mPPO was more stable than sPPO in the acidic pH range. Among the chemical inhibitors studied, oxalic acid exerted the highest inhibitory effect on mPPO, whereas EDTA showed the highest inhibitory effect on sPPO. Both sPPO and mPPO showed similar enzymatic synthesis rates in the formation of theaflavin-3'-gallate and theaflavin-3,3'-gallate. At high concentrations of the substrate, the synthesis of theaflavins was inhibited due to the presence of high levels of ester catechins. However, mPPO showed stronger stability against inhibition by ester catechins than sPPO.

Abstract Objective: The objective was to evaluate whether initiation of urate-lowering treatment (ULT) during an acute gout flare prolonged the current episode. Methods: A comprehensive search of MEDLINE and Web of Science databases was conducted from their inception to 15 March 2021. Five randomized controlled trials (RCTs) with 381 patients met the inclusion criteria. Standardized mean difference (SMD), odds ratio (OR), and 95% confidence interval (CI) were used for estimating the clinical efficacy of ULT in acute gout. Results: There was no statistical difference in days to resolution (intent-to-treat analysis) (SMD, 0.68; 95% CI — 0.42 to 1.78; I2, 49%; p = 0.22), the pain visual analogue score (VAS) by day 10 (SMD, — 0.07; 95% CI — 0.30 to 0.16; I2, 0%; p = 0.53), C-reactive protein (CRP) from day 7 to 10 (SMD, — 1.14; 95% CI — 5.63 to 3.36; I2, 55%; p = 0.62), erythrocyte sedimentation rate (ESR) from day 7 to 10 (SMD, — 2.51; 95% CI — 5.46 to 0.45; I2, 0%; p = 0.10) and the recurrence of gout flares within 28-30 days (OR 0.78; 95% CI 0.29 to 2.09; I2, 0%; p = 0.62). Conclusion: Initiation of ULT during an acute gout flare did not prolong the duration of the flare. However, larger sample size studies are needed to confirm this finding. Trial registration number PROSPERO (CRD42021234581).

Abstract Polysaccharides and anthocyanins are one of the main components of many foods, and their interaction affects the texture and nutrition of foods. The anthocyanin-polysaccharide complex was prepared from anthocyanin of plum (Prunus salicina Lindl. cv. Furong) and polysaccharide of Tremella fuciformis. The structure changes of anthocyanin and polysaccharide before and after interaction were investigated by UV-visible spectroscopy, infrared spectroscopy and scanning electron microscopy. The absorption peak at 510 nm of anthocyanin-polysaccharide complex weakened at pH 5.0, and the intensity of absorption spectrum increased with the concentration of polysaccharide. The absorption peaks of anthocyanin-polysaccharide complexes were shifted in the infrared spectral curve of anthocyanin, and the formation of complex was caused by electrostatic interaction and hydrogen bond interaction between anthocyanin and polysaccharide. From microstructural analysis, anthocyanin and polysaccharide were effectively bound together. This can provide theoretical guidance for the structural design of anthocyanin-polysaccharide food and the development and utilization of new food ingredients.
