Pectic polysaccharides (PPs) could exert functions on ulcerative colitis (UC), which is classified as a nonspecific inflammatory disorder. This study investigated the molecular mechanism of PPs derived from Rauwolfia in UC. First, the dextran sodium sulfate (DSS)-induced mouse colitis models and lipopolysaccharide (LPS)-treated colonic epithelial cell (YAMC) models were established and treated with PP. Subsequently, the effects of PPs on mucosal damages in DSS mice were detected, and the levels of inflammatory cytokines, pyroptosis-related factors, oxidative stress-related markers, and the tight junction-related proteins in the tissues or cells were examined, and the results suggested that PPs ameliorated colonic mucosal damages and cell pyroptosis in DSS mice, and limited colonic epithelial cell pyroptosis in in vitro UC models. Subsequently, the binding relations of retinol-binding protein 4 (RBP4) to miR-124-3p and NLR pyrin domain-containing 3 (NLRP3) were analyzed. miR-124-3p targeted RBP4 and reduced the binding of RBP4 to NLRP3, thus inhibiting NLRP3-mediated pyroptosis. Finally, functional rescue experiments revealed that miR-124-3p suppression or RBP4 overexpression promoted colonic epithelial cell pyroptosis. Collectively, Rauwolfia-derived PPs limited miR-124-3p and targeted RBP4 and reduced the binding potency of RBP4 to NLRP3 to inhibit NLRP3-mediated pyroptosis, resulting in the alleviation of colonic epithelial cell pyroptosis and mucosal damages in UC.

Through the salification reaction of carboxylation, successful attachment of the long-chain alkanoic acid to the two ends of 1,3-propanediamine was realized, which enabled the doubling of the long-chain alkanoic acid carbon chain. Hydrous 1,3-propanediamine dihexadecanoate (abbreviated as 3C16) and 1,3-propanediamine diheptadecanoate (abbreviated as 3C17) were synthesized afterward, and their crystal structures were characterized by the X-ray single crystal diffraction technique. By analyzing their molecular and crystal structure, their composition, spatial structure, and coordination mode were determined. Two water molecules played important roles in stabilizing the framework of both compounds. Hirshfeld surface analysis revealed the intermolecular interactions between the two molecules. The 3D energy framework map presented the intermolecular interactions more intuitively and digitally, in which dispersion energy plays a dominant role. DFT calculations were performed to analyze the frontier molecular orbitals (HOMO–LUMO). The energy difference between the HOMO–LUMO is 0.2858 eV and 0.2855 eV for 3C16 and 3C17, respectively. DOS diagrams further confirmed the distribution of the frontier molecular orbitals of 3C16 and 3C17. The charge distributions in the compounds were visualized using a molecular electrostatic potential (ESP) surface. ESP maps indicated that the electrophilic sites are localized around the oxygen atom. The crystallographic data and parameters of quantum chemical calculation in this paper will provide data and theoretical support for the development and application of such materials.

Existence of cuticle wax layer not only reduces the drying rate of blueberries but also causes the fruit to burst during drying. Such a phenomenon results in undesirable appearance as well as in losses of bioactive compounds responsible for health benefits and in sugars adhering to the surface and hence increased moisture adsorption capability of the dried fruit. In this study, uses of CO2 laser perforation, ultrasound and freezing–thawing as skin pretreatments prior to infrared freeze drying and their effects on drying characteristics as well as selected properties, i.e., shrinkage, color, rehydration capacity, as well as total anthocyanins and phenolics contents, of blueberries were investigated. Fourier transform infrared (FTIR) spectra of the dried fruit were also determined. Pretreatments increased drying rate and rehydration capacity of blueberries; shrinkage reduced from around 57 to 25%. Laser perforation and freezing–thawing but not ultrasonic pretreatments exhibited no significant effects on color of blueberries. Laser perforation and ultrasonic pretreatments exerted positive effects on the total phenolic and anthocyanin contents of the dried samples, respectively. FTIR spectra illustrated that all pretreatments did not alter the chemical fingerprints of the dried fruit powder.

The nutrient and antioxidant content in blueberries were significantly higher than cranberries and raspberries, except crude fiber. Fourier infrared spectroscopy was used to characterize quantitati...

Background and aims In patients with left main coronary artery disease (LMCAD), long-term outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DES) compared with coronary artery bypass grafting (CABG) remain controversial. We conducted a meta-analysis to compare the efficacy and safety of PCI with DES and CABG in LMCAD patients. Methods We comprehensively searched in Web of Science, EMBASE, PubMed, and Cochrane databases for eligible randomised controlled trials (RCTs) comparing the 5-year clinical outcomes between PCI with DES and CABG in LMCAD patients. Random-effect models were applied to analyse risk ratios (RRs) and hazard ratios (HRs) across studies, and I2 to assess heterogeneity. Results We screened 4 RCTs including 4394 patients distributed randomly into PCI (n = 2197) and CABG (n = 2197) groups. In comparison to CABG, PCI showed non-inferiority concerning a composite of death, myocardial infarction, and stroke (HR 1.22, 95% confident interval [CI] 0.84–1.75), death (HR 1.06, 95% CI 0.81–1.40) and stroke (HR 0.80, 95% CI 0.42–1.53). Regarding major adverse cardiac or cerebrovascular events (MACCE) rate, both strategies show clinical equipoise in patients with a low-to-intermediate Synergy Between PCI with TAXUS and Cardiac Surgery (SYNTAX) score (HR 1.20, 95% CI 0.85–1.70), while CABG had an advantage over PCI in those with a high SYNTAX score (HR 1.64, 95% CI 1.20–2.24). Conclusions CABG showed advantage over PCI with DES for LMCAD patients in MACCE. PCI and CABG showed equivalent 5-year clinical risk of a composite of all-cause mortality, myocardial infarction, and stroke, but the former had higher risk of repeat revascularization.

The SNF5-type protein BUSHY plays a role in the regulation of seed germination via the gibberellin pathway dependent on HUB1 in Arabidopsis thaliana. SWITCH/SUCROSE NONFERMENTING (SWI/SNF) complexes play diverse roles in plant development. Some components have roles in embryo development and seed maturation, however, whether the SNF5-type protein BUSHY (BSH), one of the components, plays a role in Arabidopsis seed related traits is presently unclear. In our study, we show that a loss-of-function mutation in BSH causes increased seed germination in Arabidopsis. BSH transcription was induced by the gibberellin (GA) inhibitor paclobutrazol (PAC) in the seed, and BSH regulates the expression of GA pathway genes, such as Gibberellin 3-Oxidase 1 (GA3OX1), Gibberellic Acid-Stimulated Arabidopsis 4 (GASA4), and GASA6 during seed germination. A genetic analysis showed that seed germination was distinctly improved in the bshga3ox1ga3ox2 triple mutant, indicating that BSH acts partially downstream of GA3OX1 and GA3OX2. Moreover, the regulation of seed germination by BSH in response to PAC is dependent on HUB1. These results provide new insights and clues to understand the mechanisms of phytohormones in the regulation of seed germination.

Objectives To evaluate the 3-year clinical outcomes of a polymer-free sirolimus-eluting, Nano plus stent for the treatment of coronary artery disease in the NANO multicenter Registry. Background The long-term clinical data evaluating the safety and efficacy of the novel polymer-free sirolimus-eluting Nano plus stent (Lepu Medical, Beijing, China) is limited. Methods The NANO all-comers Registry trial was a prospective, multicenter clinical registry conducted in 26 centers in China between August 2016 and January 2017. A total of 2481 consecutive patients were exclusively treated with the Nano plus stent. The primary clinical endpoint, target lesion failure (TLF, defined as cardiac death, target vessel nonfatal myocardial infarction, and clinically driven target lesion revascularization [CD-TLR]), was analyzed at 3 years. Results At 3 years, 2295 patients (92.5%) were followed. The incidence of TLF was 6.8% (168/2481). The rate of cardiac death was 3.8% (94/2481), target vessel nonfatal myocardial infarction 0.7% (18/2481), and CD-TLR 2.9% (68/2481). The rate of definite/probable stent thrombosis was 0.5% (13/2481). The risk factors of diabetes mellitus, acute myocardial infarction, age, chronic renal failure, in-stent restenosis, chronic total occlusion, and left ventricular ejection fraction Conclusions At three years, the rate of TLF was relatively low in patients treated with the polymer-free Nano plus stent. The polymer-free Nano plus stent showed a favorable safety and efficacy profile in real-world patients. Clinical trial registration URL: https://www.clinicaltrials.gov/. Unique identifier: NCT02929030.

Background The incidence of placenta preiva is rising. Cesarean delivery is identified as the only safe and appropriate mode of delivery for pregnancies with placenta previa. Anesthesia is important during the cesarean delivery. The aim of this study is to assess maternal and neonatal outcomes of patients with placenta previa managed with neuraxial anesthesia as compared to those who underwent general anesthesia during cesarean delivery. Methods A retrospective cohort study was performed of all patients with placenta preiva at our large academic institution from January 1, 2014 to June 30, 2019. Patients were managed neuraxial anesthesia and general anesthesia during cesarean delivery. Results We identified 1234 patients with placenta previa who underwent cesarean delivery at our institution. Neuraxial anesthesia was performed in 737 (59.7%), and general anesthesia was completed in 497 (40.3%) patients. The mean estimated blood loss at neuraxial anesthesia of 558.96 ± 42.77 ml were significantly lower than the estimated blood loss at general anesthesia of 1952.51 ± 180 ml (p Conclusions Our data demonstrated that neuraxial anesthesia is associated with better maternal and neonatal outcomes during cesarean delivery in women with placenta previa.

Background: To investigate current knowledge, attitudes, and practices for CPR quality control among emergency physicians in Chinese tertiary hospitals.Methods: Anonymous questionnaires were distributed to physicians in 75 tertiary hospitals in China between January and July 2018.Results: A total of 1405 respondents answered survey without obvious logical errors. Only 54.4% knew all criteria of high-quality CPR. The main problems during CPR were related to chest compression: low quality due to fatigue (67.3%), inappropriate depth (57.3%) and rate (54.1%). 91.0% respondents considered CPR quality monitoring should be used, 72.4% knew objective method for monitoring, and 63.2% always/often monitored CPR quality during actual resuscitation. The utilization rate of recommended monitoring methods was reported as follow, ETCO2 was 42.7%, audio-visual feedback devices was10.1%, coronary perfusion pressure was 17.9%, and invasive arterial pressure was 31.1%. 96.3% respondents considered it was necessary to participate in regular CPR retraining, but 21.4% did not receive any retraining. The ideal retraining interval was considered to be 3 to 6 months, but actual interval was 6 to 12 months. CPR feedback devices were always/often used in training was reported by 49.7% of respondents.Conclusion: Chinese emergency physicians were very concerned about CPR quality, but they did not fully understand the high-quality criteria and impact on prognosis. CPR quality monitoring was not routine procedure during actual resuscitation. The methods recommended in guidelines were rarely used in practice. Many physicians have not received retraining or have received retraining at long intervals. Feedback devices were not commonly used in training.

From early life to adulthood, the microbiota play a crucial role in the health of the infant. The microbiota in early life are not only a key regulator of infant health but also associated with long-term health. Pregnancy to early life is the golden time for the establishment of the infant microbiota, which is affected by both environmental and genetic factors. Recently, there is an explosion of the studies on the role of microbiota in human diseases, but the application to disease or health is relatively limited because many aspects of human microbiota remain controversial, especially about the infant microbiota. Therefore, a critical and conclusive review is necessary to understand fully the relationship between the microbiota and the health of infant. In this article, we introduce in detail the role of microbiota in the infant from pregnancy to early life to long-term health. The main contents of this article include the relationship between the maternal microbiota and adverse pregnancy outcomes, the establishment of the neonatal microbiota during perinatal period and early life, the composition of the infant gut microbiota, the prediction of the microbiota for long-term health, and the future study directions of microbiota.

Background Placenta previa, a serious obstetric issue, should be managed by experienced teams. The safe and appropriate mode of delivery for placenta previa is by cesarean delivery. However, no studies were found comparing either maternal or neonatal outcomes for different skin incision in women with placenta previa. The aim of this study was to compare maternal and neonatal outcomes by skin incision types (transverse compared with vertical) in a large cohort of women with placenta previa who were undergoing cesarean delivery. Methods This was a retrospective cohort study carried out between January 2014 and June 2019. All pregnant women with placenta previa had confirmed by ultrasonologist before delivery and obstetrician at delivery. The primary outcome was the estimated blood loss during the surgery and within the first 24 hours postoperatively. Mean (standard deviation), median (interquartile range) or frequency (percentage) was reported to variables. Appropriate parametric and nonparametric tests were used to analyses. Results The study included 1098 complete records, 332 (30.24%) cases in the vertical skin incision group and 766 (69.76%) cases in the transverse skin incision group. Those with vertical incision showed a higher percentage of preterm delivery, anterior placenta, abnormally invasive placenta, and history of previous cesarean delivery, and a lower percentage of first pregnancy, in vitro fertilization, and emergency cesarean delivery. After controlling for confounding factors, higher incidence of post-partum hemorrhage (OR 5.47, 95% CI 3.84–7.79), maternal intensive care unit (OR 4.30, 95% CI 2.86–6.45), transfusion (OR 5.97, 95% CI 4.15–8.58), and 5-min APGAR< 7 (OR 9.03, 95% CI 1.83–44.49), a more estimated blood loss (β 601.85, 95%CI 458.78–744.91), and a longer length of hospital stay after delivery (β 0.54, 95%CI 0.23–0.86) were found in the vertical skin incision group. Conclusions Our data demonstrated that transverse skin incision group showed the better perinatal outcomes in women with placenta previa. Future collaborative studies are needed to be done by centers for placenta previa to have a better understanding of the characteristics and the outcomes of the disease in the choosing skin incision.

Aims: To investigate current practices and problems of neurological prognostication in comatose cardiac arrest (CA) patients. Methods: An anonymous questionnaire was distributed to 1600 emergency physicians in 75 hospitals which were selected randomly from China between January and July 2018. Results: 92.1% respondents fulfilled the survey. The details of the neurological prognosis were not well understood. The predictive value of brain stem reflex, motor response and myoclonus was confirmed by 63.5%, 44.6% and 31.7% respondents respectively. Only 30.7% knew that GWR value

To investigate the relationship between the changes of inflammatory cytokine levels and prognosis of patients with critical coronavirus disease 2019 (COVID-19) undergoing invasive mechanical ventilation (IMV).A retrospective study was conducted. The clinical date of critical COVID-19 patients undergoing IMV who were hospitalized in Wuhan Union Hospital, Tongji Medical College of Huazhong University of Science and Technology from February 4th to March 25th in 2020 were collected. At the same time, the inflammatory cytokine levels including interleukins (IL-2, IL-4, IL-6, IL-10) and tumor necrosis factor-α (TNF-α) at 48 hours before IMV and 48 hours after IMV of all the patients, as well as the 48 hours after weaning or right before death were recorded. Multivariate unconditional Logistic regression analysis was used to screen the independent risk factors of death during hospitalization.Among the 43 patients, 13 patients improved and 30 died. Compared with the survival group, the patients in the non-survival group were older (years old: 67.6±7.3 vs. 58.5±11.9, P0.05), with higher rates of hypertension, diabetes and coronary heart disease (53.3% vs. 15.4%, 63.3% vs. 23.1%, 26.7% vs. 0%, all P0.05), and the time from onset to admission to hospital, admission to ICU and IMV were longer (days: it was 9.17±5.00 vs. 5.07±2.49, 17.10±7.11 vs. 12.23±5.05, and 17.90±7.46 vs. 12.61±5.60, respectively, all P0.05). The IL-6 and TNF-α levels on 48 hours after IMV in the non-survival patients increased significantly as compared with those before 48 hours and the surviving patients. Especially, the IL-6 levels increased significantly as compared with those at 48 hours after IMV and 48 hours after weaning in the surviving patients [ng/L: 800.00 (194.25, 2 000.00) vs. 22.03 (6.66, 28.21), 3 204.00 (1 264.88, 5 000.00) vs. 5.00 (3.98, 12.27), both P0.01]. The IL-10 level before death in the non-survival patients increased significantly as compared with that at 48 hours after weaning in the surviving patients [ng/L: 55.89 (26.07, 100.14) vs. 3.53 (2.76, 12.36), P0.05]. There were no significant differences in the levels of IL-2 and IL-4 between the two groups at every time point. The variables of age, basic diseases, the IL-6 level after IMV were included in the multivariate unconditional Logistic regression analysis, which showed that age [odds ratio (OR) = 0.821, 95% confidence interval (95%CI) was 0.695-0.968], hypertension (OR = 0.027, 95%CI was 0.002-0.378), diabetes mellitus (OR = 0.054, 95%CI was 0.005-0.611), coronary heart disease (OR = 0.042, 95%CI was 0.002-0.968) and the IL-6 level after IMV (OR = 0.902, 95%CI was 0.819-0.994) were independent risk factors for death during hospitalization in patients with critical COVID-19 undergoing IMV (all P0.05).The levels of inflammatory cytokine including IL-6, IL-10, and TNF-α increased significantly with aggravation in critical COVID-19 patients undergoing IMV, especially IL-6. IL-6 was an independent risk factor for death of critical COVID-19 patients undergoing IMV.

The potential of tetrazole-based ligands for forming energetic complexes applied in pyrotechnics and propellants is demonstrated with the use of 5,5’-(1,3-phenylene)bis(1H-tetrazole) (H2BTB) to generate an energetic complex with high energy. A new energetic complex of PbII-tetrazolate, [Pb2(BTB)2(H2O)8]·5H2O (1), was synthesized and structurally characterized by single crystal X-ray diffraction. Structural analysis reveals that the central PbII ions present two distinct coordination environments in the asymmetric unit, including distorted pentagonal bipyramid and distorted tetragonal pyramid geometries, respectively. To identify potential combustion catalyst as additives in propellants, we employed differential scanning calorimetry technique to evaluate the influence of the complex on thermal decomposition of ammonium perchlorate (AP) and cyclotrimethylenetrinitramine (RDX). The kinetic parameters of an exothermic process for the catalytic system of RDX+1 were investigated by the Kissinger’s and Ozawa-Doyle’s methods. For both AP and RDX, the decomposition temperature decreased obviously in the presence of 1, and the released heat could effectively compensate the propellants. Our observations demonstrate that 1 shows good catalytic activity toward the thermal decomposition of AP and RDX.

Four different structures of manganese dioxide particles with good dispersity were obtained using hydrothermal and co-precipitation methods. Magnetic measurement reveals that α-MnO2 exhibits a spin-glass like behavior below 50 K which is different from bulk α-MnO2. β-MnO2 and δ-MnO2 exhibit a transition from the paramagnetic to antiferromagnetic state at 92 K and 20 K, respectively, and γ-MnO2 retains the paramagnetic state during the temperature range of measurement. Besides, δ-MnO2 possesses the highest magnetization while β-MnO2 has the lowest magnetization. The thermodynamic properties of these manganese dioxides were further studied using heat capacity measurements, and the results confirmed magnetic transition at the corresponding temperatures revealed in the above magnetic measurements. Through fitting the heat capacity curve, the standard molar heat capacity, entropy and enthalpy at 298.15 K (0.1 MPa) and transition enthalpy were obtained in this work. Based on the characterization results, it is supposed that impurity ions/molecules and vacancies are the main factors that contribute to the magnetic performance of δ-MnO2, although the layer structure is thought to be an origin of ferromagnetic interaction.

Three novel carboxylic arylhydrazone compounds named 2- oxo propionic acid terephthalal acyl dihydrazone (1), 2-ketoglutaric acid terephthalal acyl dihydrazone (2) and 2-ketoglutaric acid salicyl- hydrazone (3) were prepared and characterized by elemental analysis, IR and 1H NMR. The antibacterial activities of 1 and 2 against wheat rust and coliform were investigated. The results showed that 1 had more excellent antibacterial properties than 2 against both wheat rust and coliform. In addition, the title compounds interaction with calf-thymus DNA (CT-DNA) were measured by fluorescence spectra method which indicating that they combined with CT-DNA by groove binding through hydrogen bonds.

Hypoxia/reoxygenation (H/R) is used as an in vivo model of ischemia/reperfusion injury, and myocardial ischemia can lead to heart disease. Therefore, it is necessary to prevent myocardial H/R injury to avoid the risk of heart disease. The aim of the present study was to investigate whether inhibiting microRNA (miR)-101a-3p attenuated H9C2 cell H/R injury, apoptosis mechanisms and key target proteins. Cell viability and apoptosis were determined by Cell Counting Kit-8 assays and flow cytometry using a cell apoptosis kit, respectively. The contents of creatine kinase (CK) and lactate dehydrogenase (LDH) were detected using colorimetric assays. Dual luciferase assays were carried out to determine if miR-101a-3p inhibited Janus kinase (JAK)2. Western blot analysis and reverse transcription-quantitative PCR were used to determine proteins levels and mRNAs expression. It was found that the inhibition of miR-101a-3p increased the growth of H9C2 cells and decreased H9C2 cell apoptosis during H/R injury. The inhibition of miR-101a-3p reduced the amounts of CK and LDH in H/R model H9C2 cells. The inhibition of miR-101a-3p lowered the levels of Bax, interleukin-6 and tumor necrosis factor-α, but raised the levels of phosphorylated (p)-STAT3 and p-JAK2 in H9C2 cells subjected to H/R injury treatment. miR-101a-3p mimic was found to inhibit H9C2 cell viability, raise p-JAK2 level and slightly increase p-STAT3 during H/R injury. AG490 induced H9C2 cell apoptosis, and decreased the levels of p-JAK2 and p-STAT3 during H/R injury. The data indicated that inhibiting miR-101a-3p reduced H/R damage in H9C2 cells and decreased apoptosis via Bax/Bcl-2 signaling during H/R injury. In addition, it was suggested that the inhibition of miR-101a-3p decreased H/R injury in H9C2 cell by regulating the JAK2/STAT3 signaling pathway.

The asymmetric unit of the title salt, 2C12H28N+·SO4 2−·3H2O, contains two n-dodecylammonium cations, one sulfate anion and three water molecules. In the crystal, N—H...O hydrogen bonds link the cations and anions into layers parallel to (100). These layers are further connected through O—H...O hydrogen-bonding interactions involving the sulfate ions and the isolated water molecules. The three-dimensional structure can also be considered as the superposition of thin inorganic layers of SO4 2− anions and thick layers of alkylammonium cations perpendicular to the c axis.

The molecular mechanisms underlying seed dormancy and germination are not fully understood. Here, we show that Arabidopsis thaliana SEED DORMANCY 4-LIKE (AtSdr4L) is a novel specific regulator of dormancy and germination. AtSdr4L encodes a protein with an unknown biochemical function that is localized in the nucleus and is expressed specifically in seeds. Loss of function of AtSdr4L results in increased seed dormancy. The germination of freshly harvested seeds of the Atsdr4l mutant is insensitive to gibberellin (GA). After-ripened mutant seeds are hypersensitive to the GA biosynthesis-inhibitor paclobutrazol but show unaltered sensitivity to abscisic acid. Several GA biosynthesis genes and GA-regulated cell wall remodeling genes are down-regulated in the mutant in both dormant and after-ripened seeds. These results suggest that the Atsdr4l mutation causes both decreased GA biosynthesis and reduced responses. In addition, a genetic analysis indicated that AtSdr4L is epistatic to DELAY OF GERMINATION1 (DOG1) for dormancy and acts upstream of RGA-LIKE 2 (RGL2) in the GA pathway. We propose that AtSdr4L regulates seed dormancy and germination by mediating both the DOG1 and GA pathways.

The control of seed dormancy by ethylene has been well studied, but the underlying molecular mechanisms are not fully understood. Here, we report the characterization of the Arabidopsis (Arabidopsis thaliana) mutant reduced dormancy 3 (rdo3) and the cloning of the underlying gene. We demonstrate that rdo3 is a loss-of-function mutant of the ethylene receptor ETHYLENE RESPONSE1 (ETR1). ETR1 controls seed dormancy partially through the DELAY OF GERMINATION1 (DOG1) pathway. Molecular and genetic analyses demonstrated that ETHYLENE RESPONSE FACTOR12 (ERF12) is involved in the regulation of seed dormancy downstream of ETR1. ERF12 interacts with TOPLESS (TPL) and genetically requires TPL to function. ERF12 and TPL repress the expression of DOG1 by occupying its promoter. Thus, we identified the dormancy pathway ETR1-ERF12-TPL-DOG1 and provide mechanistic insights into the regulation of seed dormancy by linking the ethylene and DOG1 pathways.
