The low-temperature electrochemical corrosion behavior of aircraft 2024 aluminum alloy was investigated in different concentrations of potassium-acetate-type fluid, and the results showed that the corrosion medium initially impacted some corrosiveness on the 2024 aluminum alloy. However, the corrosion rate of the alloy decreased with prolonged immersion in the corrosion medium, and this was attributed to the protective effect of the corrosion products layer, which impeded the attack by the aggressive solution. Time-domain analysis of electrochemical noise measurements at -5 °C revealed the occurrence of uniform corrosion on the alloy at the initial stages of immersion, general corrosion at the middle stages of immersion, and a pitting-dominated corrosion type from the middle to late stages of immersion.

Abstract Dendrobium nobile is a traditional Chinese medicine and functional food in China, with anti-aging, immunity-enhancing, glucose-lowering and lipid-lowering health functions. In recent years, the research value of D. nobile has attracted the attention of more and more experts and scholars. Today, phytochemical investigation of the stems of Dendrobium nobile Lindl., led to the isolation of five sesquiterpene glycosides, including dendromoniliside D (1), dendronobiloside A (2), dendronobiloside C (3), dendronobiloside D (4), dendroside G (5) and their α-amylase and α-glycosidase inhibitory activities were also investigated. Among them, dendromoniliside D (1), dendroside G (5) were first isolated from D. nobile. And dendronobiloside A (2) and dendronobiloside C (3) exhibited better inhibitory activity against α-glycosidases, respectively. In the case of α-amylase inhibition, dendroside G (5) has a relatively good effect. These results suggest that sesquiterpene glycosides of D. nobile have potential hypoglycemic activity and deserve further research and development.

Abstract Background Alpha-kinase 1 (ALPK1) is a master regulator in inflammation and has been proved to promote renal fibrosis by promoting the production of IL-1β in diabetic nephropathy (DN) mice. Pyroptosis is involved in high glucose (HG)-induced tubular cells injury, characterized by activation of Gasdermin D (GSDMD) and the release of IL-1β and IL-18, resulting in inflammatory injury in DN. It is reasonable to assume that ALPK1 is involved in pyroptosis-related tubular injury in DN. However, the mechanism remains poorly defined. Methods Immunohistochemistry (IHC) staining was performed to detect the expression of pyroptosis- and fibrosis-related proteins in renal sections of DN patients and DN mice. DN models were induced through injection of streptozotocin combined with a high-fat diet. Protein levels of ALPK1, NF-κB, Caspase-1, GSDMD, IL-1β, IL-18 and α-SMA were detected by Western blot. HK-2 cells treated with high-glucose (HG) served as an in vitro model. ALPK1 small interfering RNA (siRNA) was transfected into HK-2 cells to down-regulate ALPK1. The pyroptosis rates were determined by flow cytometry. The concentrations of IL-1β and IL-18 were evaluated by ELISA kits. Immunofluorescence staining was used to observe translocation of NF-κB and GSDMD. Results The heat map of differentially expressed genes showed that ALPK1, Caspase-1 and GSDMD were upregulated in the DN group. The expression levels of ALPK1, Caspase-1, GSDMD and CD68 were increased in renal biopsy tissues of DN patients by IHC. ALPK1expression and CD68+ macrophages were positively correlated with tubular injury in DN patients. Western blot analysis showed increased expressions of ALPK1, phospho-NF-κB P65, GSDMD-NT, and IL-1β in renal tissues of DN mice and HK-2 cells, accompanied with increased renal fibrosis-related proteins (FN, α-SMA) and macrophages infiltration in interstitial areas. Inhibition of ALPK1 attenuated HG-induced upregulation expressions of NF-κB, pyroptosis-related proteins Caspase-1, GSDMD-NT, IL-1β, IL-18, α-SMA, and pyroptosis level in HK-2 cells. Also, the intensity and nuclear translocation of NF-κB and membranous translocation of GSDMD were ameliorated in HG-treated HK-2 cells after treatment with ALPK1 siRNA. Conclusions Our data suggest that ALPK1/NF-κB pathway initiated canonical caspase-1-GSDMD pyroptosis pathway, resulting in tubular injury and interstitial inflammation of DN.

Abstract Dendrobium officinale is a famous traditional Chinese medicine and nourishing food in China. The active constituents in D. officinale include a variety of chemical components such as polysaccharides, bibenzyl, phenanthrenes, and flavonoids etc. Among them, polysaccharide was selected as the quality control marker for D. officinale in the Chinese Pharmacopoeia. The previous studies found that the content of polysaccharide constituents in D. officinale from different growing origins had significant differences. To the best of our knowledge, whether the secondary metabolites other than polysaccharides are similarly different in D. officinale from different origins has not been reported. In the present continuing study, UPLC-Q/TOF-MS coupled with multivariate analysis were employed for comparative analysis of the secondary metabolites of D. officinale from different growing origins. At last, 12 differential secondary metabolites of D. officinale from different origins were identified. Network pharmacological analysis results indicated that these differential secondary metabolites of D. officinale from different origins are mainly involved in neuropsychiatric related disorder diseases. This investigation will provide a valuable information for doctors and consumers in clinical practice.

This study evaluated the effects of perioperative nutrition management by a multidisciplinary team on nutrition and postoperative complications of patients with esophageal cancer. A total of 239 patients with esophageal cancer who underwent esophagectomy and gastric conduit reconstruction for esophageal or esophagogastric junction cancer between February 2019 and February 2020 were included in the study. They were divided into the experimental group (120 patients) and the control group (119 patients) using the random number table method. Control group patients received routine diet management and experimental group patients received perioperative nutrition management by a multidisciplinary team. The differences of nutriture and postoperative complications between the two groups were compared. At 3 and 7 days after surgery, the experimental group patients had higher total protein and albumin levels (P<0.05), shorter postoperative anal exhaust time (P<0.05), lower incidence of postoperative gastrointestinal adverse reactions, pneumonia, anastomotic fistula, hypoproteinemia (P<0.05), and lower hospitalization costs (P<0.05) than the control group. Nutrition management by a multidisciplinary team effectively improved the nutriture of patients, promoted the rapid recovery of postoperative gastrointestinal function, reduced postoperative complications, and reduced hospitalization costs.

Resumo Introdução A manobra de Epley é útil para o retorno da otocônia do braço longo do canal semicircular posterior para o utrículo. Diferentes manobras são necessárias para mover a otocônia para fora do braço curto do canal semicircular posterior e para dentro do utrículo. Objetivo Diagnosticar a VPPB do tipo braço curto do canal semicircular posterior e tratá-la com a manobra de incline and balance. Método Foram diagnosticados 171 casos como VPPB de canal semicircular posterior com base na manobra de Dix-Hallpike positiva. Primeiro tentamos tratar os pacientes com a manobra de incline and balance e, em seguida, executamos a manobra de Dix-Hallpike novamente. Se a repetição da manobra de Dix-Hallpike desse resultados negativos, diagnosticávamos o paciente como VPPB do canal semicircular posterior do tipo braço curto e considerávamos que ele ou ela havia sido curado pela manobra de incline and balance; caso contrário, provavelmente o paciente apresentava VPPB do canal semicircular posterior do tipo braço longo e tratávamos o paciente com a manobra de Epley. Resultados Aproximadamente 40% dos casos foram curados pela manobra de incline and balance, com resultados negativos nas manobras de Dix-Hallpike repetidas, e foram diagnosticados com litíase de braço curto. Conclusão A VPPB de canal semicircular posterior do tipo braço curto pode ser diagnosticada e tratada de maneira conveniente e confortável.

Abstract Introduction The Epley maneuver is useful for the otoconia to return from the long arm of the posterior semicircular canal into the utricle. To move otoconia out of the posterior semicircular canal short arm and into the utricle, we need different maneuvers. Objective To diagnose the short-arm type BPPV of the posterior semicircular canal and treat them with bow-and-yaw maneuver. Methods 171 cases were diagnosed as BPPV of the posterior semicircular canal based on a positive Dix-Hallpike maneuver. We first attempted to treat patients with the bow-and-yaw maneuver and then performed the Dix-Hallpike maneuver again. If the repeated Dix-Hallpike maneuver gave negative results, we diagnosed the patient with the short-arm type of BPPV of the posterior semicircular canal and considered the patient to have been cured by the bow-and-yaw maneuver; otherwise, probably the long-arm type BPPV of the posterior semicircular canal existed and we treated the patient with the Epley maneuver. Results Approximately 40% of the cases were cured by the bow-and-yaw maneuver, giving negative results on repeated Dix-Hallpike maneuvers, and were diagnosed with short-arm lithiasis. Conclusion The short-arm type posterior semicircular canal BPPV can be diagnosed and treated in a convenient and comfortable manner.

Abstract The high-methoxyl pectin of citrus was used to prepare a fat substitute and applied to the processing technology of moon-cake skin. The physical, chemical, and sensory properties of fat substitutes and prepared moon-cake skins were studied by selecting texture properties, rheological properties, water distribution, and water-holding capacity. Results showed that the gel hardness of glucan–sucrose (G-SG) (glucan/sucrose = 4:6) as synergistic gel was 6.23 ± 0.10 N, the elasticity was 3.97 ± 0.03 mm, the adhesive viscosity was 4.87 ± 0.20 N, the chewiness was 16.87 ± 0.51 mj, the water-holding capacity was 98.33%, and the gel obtained from sucrose (SG) as gelation agent had no significant difference (P > 0.05). The consistency coefficient and thixotropic circle area of G-SG was larger than that of SG. Through dynamic viscoelastic scanning, we found that the tanδ of G-SG was smaller, and it had stronger hydrophobic interaction and stronger fluid properties after high-speed shear. It also more easily maintained a flow state similar to oil. G-SG was further applied to the processing technology of low-fat moon-cake skin. The color of the prepared low-fat moon-cake skin darkened, the water-holding capacity was enhanced, the fat content decreased from 22.21% ± 0.54% to 14.07% ± 0.57%, the oil droplets enlarged, and flocculation strengthened. Results of texture-characteristic and sensory-score analyses showed no significant difference (P > 0.05) from the control group when the oil substitution amount was 40%. At this time, the total sensory score was 41.71 ± 2.02.

Abstract To investigate the effect of corosolic acid treatment on erectile function in metabolic syndrome induced rat model. Fifty male 3-week-old SD rats were fed a high fat and high sugar diet. Six months later, metabolic variables were determined. Metabolic syndrome induced erectile function (MED) rats were confirmed by an apomorphine test. Then MED rats were treated with corosolic acid daily by oral gavage for 4 weeks. To evaluate erectile function, intracavernosal pressure (ICP)/mean arterial blood pressure (MAP) ratio was measured. Thiobarbituric acid reactive substances assay and dihydroethidium staining were used to assess reactive oxygen species (ROS) level. Protein expressions of gp91phox and eNOS were examined by western blotting and immunohistochemistry. Fasting blood glucose, body weight, total cholesterol and insulin were markedly increased in metabolic syndrome rats compared with those of the control rats (p < 0.05). The ratios of max ICP/MAP and area under curve (AUC)/MAP was markedly reduced in MED rats compared with the control rats (p < 0.05). The concentration of cyclic guanosine mono-phosphate (cGMP) and the expression of eNOS were significantly decreased in MED rats compared with the control group (p < 0.05). Moreover, ROS level and the expression of gp91phox were significantly increased in MED rats. Treatment with corosolic acid reversed these changes (each p < 0.05). Corosolic acid reduces the level of ROS, ameliorating endothelial dysfunction and improvement of erectile function in MED rats.

ABSTRACT Introduction: Severe fever with thrombocytopenia syndrome virus (SFTSV) is a newly emerged virus that poses a great threat to human health because of high fatality rate. Methods: To develop sensitive and specific sero-diagnostic systems for SFTSV infections, monoclonal antibodies (MAbs) against recombinant SFTSV nucleocapsid (rSFTSV-N) protein were developed by immunizing BALB/C mice with rSFTSV-N protein and fusing the spleen cells with SP2/0 myeloma cells. Three hybridoma cell lines secreting MAbs against rSFTSV-N were obtained. MAb based IgG sandwich enzyme linked immunosorbent assay (ELISA) and IgM capture ELISA systems were established by using the newly developed MAbs. One hundred fifteen clinical suspected SFTS patients serum samples were used to evaluate the newly established systems by comparing with the total antibody detecting sandwich ELISA system and indirect ELISA systems. Results: The MAbs based sandwich IgG ELISA was perfectly matched with that of the total antibody sandwich ELISA and the indirect IgG ELISA. IgM capture ELISA results perfectly matched with that of the total antibody sandwich ELISA while detecting eight additional positive samples missed by the indirect IgM ELISA. Conclusions: The MAbs against rSFTSV-N protein offer new tools for SFTSV studies and our newly developed MAb-based IgG and IgM capture ELISA systems would offer safe and useful tools for diagnosis of SFTS virus infections and epidemiological investigations.

Abstract Objective: To investigate the impact of recombinant human interferon α1b (rhIFNα1b) treatment in infants hospitalized with lower respiratory tract infections on subsequent wheezing. Methods: The clinical data of infants (n = 540) with viral pneumonia, wheezy bronchitis, or bronchiolitis hospitalized in 19 Chinese hospitals from June 2009 to June 2015 were retrospectively analyzed. The parameters relevant to wheezing episodes within the last year were collected by telephone and questionnaires. The rhIFNα1b treatment group (n = 253) and control group (n = 287) were compared in terms of wheezing episodes within the last year. Moreover, the wheezing group (95 cases) and non-wheezing group (445 cases) were compared. Results: Out of 540 cases, 95 (17.6%) experienced wheezing episodes, 13.8% (35/253) cases treated with rhIFNα1b, and 20.9% (60/287) cases without rhIFNα1b experienced wheezing episodes within the last year. The rhIFNα1b treatment significantly improved wheezing episodes within the last year, compared with the control peers (p = 0.031). Single-factor regression showed statistically significant differences between the wheezing and non-wheezing groups in terms of age, rhIFNα1b use, childhood and family history of allergy, housing situation, and feeding history (p < 0.05). Binary logistic regression showed a childhood history of allergy (OR = 2.14, p = 0.004), no rhIFNα1b use (OR = 1.70, p = 0.028), and living in a crowded house (OR = 1.92, p = 0.012) might be risk factors of subsequent wheezing. Accordingly, breastfeeding (OR = 0.44, p = 0.008) and hospitalization age of 1-year-old (OR = 0.58, p = 0.024) were protective factors. Conclusions: Early use of rhIFNα1b in infants hospitalized with lower respiratory tract infections and breastfeeding could prevent subsequent wheezing. Living in a crowded house could promote subsequent wheezing.

Resumo Fundamento: A fração de ejeção (FE) tem sido utilizada em análises fenotípicas e na tomada de decisões sobre o tratamento de insuficiência cardíaca (IC). Assim, a FE tornou-se parte fundamental da prática clínica diária. Objetivo: Este estudo tem como objetivo investigar características, preditores e desfechos associados a alterações da FE em pacientes com diferentes tipos de IC grave. Métodos: Foram incluídos neste estudo 626 pacientes com IC grave e classe III–IV da New York Heart Association (NYHA). Os pacientes foram classificados em três grupos de acordo com as alterações da FE, ou seja, FE aumentada (FE-A), definida como aumento da FE ≥10%, FE diminuída (FE-D), definida como diminuição da FE ≥10%, e FE estável (FE-E), definida como alteração da FE <10%. Valores p inferiores a 0,05 foram considerados significativos. Resultados: Dos 377 pacientes com IC grave, 23,3% apresentaram FE-A, 59,5% apresentaram FE-E e 17,2% apresentaram FE-D. Os resultados mostraram ainda 68,2% de insuficiência cardíaca com fração de ejeção reduzida (ICFEr) no grupo FE-A e 64,6% de insuficiência cardíaca com fração de ejeção preservada (ICFEp) no grupo FE-D. Os preditores de FE-A identificados foram faixa etária mais jovem, ausência de diabetes e fração de ejeção do ventrículo esquerdo (FEVE) menor. Já os preditores de FE-D encontrados foram ausência de fibrilação atrial, baixos níveis de ácido úrico e maior FEVE. Em um seguimento mediano de 40 meses, 44,8% dos pacientes foram vítimas de morte por todas as causas. Conclusão: Na IC grave, a ICFEr apresentou maior percentual no grupo FE-A e a ICFEp foi mais comum no grupo FE-D.

Abstract Background: Ejection fraction (EF) has been used in phenotype analyses and to make treatment decisions regarding heart failure (HF). Thus, EF has become a fundamental part of daily clinical practice. Objective: This study aims to investigate the characteristics, predictors, and outcomes associated with EF changes in patients with different types of severe HF. Methods: A total of 626 severe HF patients with New York Heart Association (NYHA) class III–IV were enrolled in this study. The patients were classified into three groups according to EF changes, namely, increased EF (EF-I), defined as an EF increase ≥10%, decreased EF (EF-D), defined as an EF decrease ≥10%, and stable EF (EF-S), defined as an EF change <10%. A p-value lower than 0.05 was considered significant. Results: Out of 377 severe HF patients, 23.3% presented EF-I, 59.5% presented EF-S, and 17.2% presented EF-D. The results further showed 68.2% of heart failure with reduced ejection fraction (HFrEF) in the EF-I group and 64.6% of heart failure with preserved ejection fraction (HFpEF) in the EF-D group. The predictors of EF-I included younger age, absence of diabetes, and lower left ventricular ejection fraction (LVEF). The predictors of EF-D were absence of atrial fibrillation, lower uric acid level, and higher LVEF. Within a median follow-up of 40 months, 44.8% of patients suffered from all-cause death. Conclusion: In severe HF, HFrEF presented the highest percentage in the EF-I group, and HFpEF was most common in the EF-D group.

SUMMARY: The cutaneous wounds of trunk and tail healing scar-free or with scar were different in lizard species. Full- thickness cutaneous injuries of tail and body of Scincella tsinlingensis were examined by histomorphological and immunohistochemistrical methods. The results showed that all injuries healed without scarring. The process of the wound healing of S. tsinlingensis involved hemostasis, re-epithelialization, proliferation and remodelling, which also could be further subdivided into six stages. Stage I, 0-2 day post wound (dpw), the blood oozed gradually, no obvious wound contraction, minimal blood loss. Stage II, 2-10 dpw, the wound bed covered by the fibrin clot of blood, tissue fluid and tissue debris. Stage III, 7d-15 dpw, the wrinkled wound epitheliums was gradually stratified, and its surface was keratinized and exfoliated. Stage IV, 10-28 dpw, pigment cells were distributed at the boundary between epidermis and dermis, with few blood vessels and no granulation tissue formation. Stage V, 20-70 dpw, opaque scales covered the wound epithelium with randomly scattered melanophores in the base of the epidermis. Stage VI, 45-135 dpw, the epidermis and dermis restored to the thickness of the original skin. Regenerated scales were similar to scales of the uninjured dermis. The positive immunostaining of matrix metalloproteinases-9, cytokeratin 6, alpha smooth muscle actin, caspase 3 and transforming growth factor-β3 showed the specificity of healing period and different stages, which participated in skin wounds healing of S. tsinlingensis.

RESUMEN: En las diferentes especies de lagartos las heridas cutáneas del tronco y la cola sin cicatrices, o con algún tipo de cicatriz son diversas. En este estudio se examinaron las heridas cutáneas de espesor total de la cola y el cuerpo de Scincella tsinlingensis mediante métodos histomorfológicos e inmunohistoquímicos. Los resultados indicaron que todas las lesiones sanaron sin cicatrices visibles. El proceso de cicatrización de heridas de S. tsinlingensis implicó hemostasia, reepitelización, proliferación y remodelación, que también podrían subdividirse en seis etapas. Etapa I, 0-2 días después de la herida (dph), la sangre filtraba gradualmente, sin contracción evidente de la herida, con pérdida mínima de sangre. Etapa II, 2-10 dph, el lecho de la herida estaba cubierto por el coágulo de sangre, líquido tisular y restos tisulares de fibrina. Etapa III, 7-15 dph, los epitelios de la herida se estratificaron gradualmente y su superficie se queratiniza y exfolia. Etapa IV, 10-28 dph, las células pigmentarias se distribuyeron en el límite entre la epidermis y la dermis, con pocos vasos sanguíneos y sin formación de tejido de granulación. Etapa V, 20-70 dph, escamas opacas cubrieron el epitelio de la herida con melanóforos dispersos al azar en la base de la epidermis. Etapa VI, 45-135 dph, la epidermis y la dermis restauradas al grosor de la piel original. Las escamas regeneradas eran similares a las escamas de la dermis sin herida. La inmunotinción positiva de metaloproteinasas- 9 de matriz, citoqueratina 6, actina de músculo liso alfa, caspasa 3 y factor de crecimiento transformante-β3 mostró la especificidad del período de curación y las diferentes etapas, que participaron en la curación de heridas cutáneas de S. tsinlingensis.

Abstract A novel type of multifunctional nanocatalysts (La-/Sm-PMO-ILCl) based on the immobilization of benzotriazolium ionic liquid and further incorporation of samarium acetate or lanthanum acetate onto periodic mesoporous organosilica were afforded for the cycloaddition of CO2 and epoxides to produce cyclic carbonates. In consequence of the intramolecular synergistic effect between samarium sites of periodic mesoporous organosilica and homogeneously dispersed basic sites of ionic liquid, the powerful catalyst Sm-PMO-ILCl offered superior catalytic performance with ultra high yields and selectivities in the cycloaddition reaction without the addition of any solvent and cocatalyst. Moreover, the catalyst Sm-PMO-ILCl could be easily recovered by filtration and reused for at least five runs without any significant loss of its catalytic activity.

Resumen Se prepararon nuevos nano catalizadores (La-(Sm-PMO-ILC1) por la vía de inmovilización del líquido iónico benzotriazolium y adición se acetato de samario o acetato de lantano en organosilice mesoporosa. Los catalizadores se evaluaron en la ciclo adición de CO2 y epóxidos para producir carbonatos cíclicos. El efecto sinérgico intramolecular entre los sitios de samario de la organosilice y los sitios básicos del líquido iónico homogéneamente distribuidos inducen una alta actividad catalítica en el catalizador Sm-PMO-ILC1. Así, con este catalizador se obtuvo alta conversión y selectividad en la reacción de ciclo adición, sin agregar solvente ni co-catalizador. Además, el catalizador Sm-PMO-ILC1 podría recuperarse fácilmente por filtración y reusado por al menos 5 corridas sin pérdida significativa de su actividad catalítica.

SUMMARY: Due to the great change in the morphology of squamate vomeronasal organ (VNO), the histomorphology characteristics of VNO in Scincella tsinlingensis were studied by light and electronic microscopy. The results indicated that the VNO of S. tsinlingensis was located at the base of nasal cavity and consisted of a mushroom body situated anteroventrally and a sensory epithelium (SE) situated dorsocaudally. SE was composed of supporting cells, receptor cells and basal cells, and the supporting cells contained secretory granules near the surface membrane. Most of receptor cells were irregular in shape with long cytoplasmic extensions and characterized by microtubules, vesicles, and mitochondria. The basal cells with long cytoplasmic extensions were also irregular in shape and appeared a greater electron density than others. The thick nerve bundles were found on the dorsomedial area of VNO, and the surface of mushroom body was non-sensory epithelium consisting of ciliated and basal cells, without goblet cells. Epithelial cells were arranged in irregular, with many cilia and microvilli distributed on its free surface. Cells on the basal layer were irregularly circular in shape and arranged sparsely. Taken together, the results indicated that the fine structure of VNO in S. tsinlingensis was similar to other species from scincomorphs.
