RESUMEN

In this study, a novel quality control strategy was proposed, aiming to establish a multivariate specification for the processing step by exploring the correlation between colors, chemical components, and hemostatic effects of the carbonized Typhae pollen (CTP) using multivariate statistical analysis. The CTP samples were stir-fried at different durations. Afterward, the colorimeter and LC-MS techniques were applied to characterize the CTP samples, followed by the determination of bleeding time and clotting time using mice to evaluate their hemostatic effect. Then, principal component analysis, hierarchical cluster analysis, and multi-block partial least squares were used for data analysis on colors, chemical components, and their correlation with the hemostatic effect. Consequently, 13 critical quality attributes (CQAs) of CTP were identified via multivariate statistical analysis-L*, a*, b*, 3,4-dihydroxybenzoic acid, 4-hydroxybenzoic acid, 3-hydroxybenzoic acid, quercetin-3-O-glucoside, azelaic acid, kaempferol-3-O-glucoside, quercetin, naringenin, kaempferol, and isorhamnetin. The multivariate specification method involving the 13 CQAs was developed and visualized in the latent variable space of the partial least squares model, indicating that the proposed method was successfully applied to assess the quality of CTP and the degree of carbonization. Most importantly, this study offers a novel insight into the control of processing for carbonized Chinese herbal medicines.

RESUMEN

The researchers examined the associations between thinking styles and grit. A cross-sectional design was adopted, with two weeks of data collection. The Thinking Styles Inventory-Revised II and the Grit Scale were administered to 365 signing deaf or hard-of-hearing (DHH) Arts and Design students and 443 hearing university students in mainland China. CFA, MANOVA, hierarchical multiple regression analyses, and a multi-group analysis were executed for data analysis. DHH and hearing students with Type I styles (i.e., more creativity-generating, less structured, and cognitively more complex) had higher grit levels, with large effect sizes for the identified relationships. There were no differences in the relations for either group. The associations between thinking styles and grit may protect against psychological pressure and rehabilitation problems and enable university/school administrators, counselors, social workers, teachers, parents, and students to enhance the grit of students who are deaf or hard of hearing.

RESUMEN

Background: Chronic respiratory disease is an important public health problem in the United States and globally. Diet, an important part of a healthy lifestyle, is also relevant to chronic respiratory health. We aimed to explore the relationship between overall dietary quality and the risk of chronic respiratory disease (CRD), include chronic bronchitis (CB), emphysema and asthma. Method: A total of 4,499 United States adults were extracted from the National Health and Nutrition Examination Survey (NHANES) in 2017-2018. Diet quality was assessed using 2 day, 24 h dietary recall data and quantified as the Healthy Diet Index (HEI)-2020 score. Binary logistic regression models, restricted cubic splines (RCS) and generalized additive modeling (GAM), the weighted quartile sum (WQS) and qgcom models were used to assess the relationship between HEI-2020 scores and risk of CB, emphysema and asthma. Results: High HEI-2020 scores are associated with low risk of chronic respiratory disease (CB: 0.98, 0.97-0.99; emphysema: 0.98, 0.97-0.99; asthma: 0.98, 0.97-0.99) and consistent results across different dietary variable categorization (Tertile: CB: 0.58, 0.42-0.81; asthma: 0.51, 0.35-0.74; Quartile: CB: 0.57, 0.34-0.97; asthma: 0.56, 0.36-0.86) and different weighting models. Negative dose-response relationship between dietary quality and risk of chronic respiratory disease also shown in RCS and GAM models. The WQS and qgcom models also showed a healthy mixing effect of dietary components on respiratory disease, with high-quality proteins, vegetables, and fruits making the heaviest contributions. Conclusion: Higher HEI-2020 scores were associated with lower risk of CB, emphysema, and asthma. Following Dietary Guidelines for Americans 2020-2025 could support enhanced respiratory health.

RESUMEN

BACKGROUND: Ferroptosis, a form of regulated cell death by lipid peroxidation, was currently considered as a key factor affecting the occurrence and progression in various cancers. Andrographolide (ADE), a major effective ingredient of Andrographis paniculate, has proven to have a substantial anti-tumor effect on multiple cancer types. However, the function and underlying mechanism of ADE in Non-Small Cell Lung Cancer remain unclear. METHODS: CCK8 assay, colony-formation assay, flow cytometry, scratch test, transwell assay, western blotting, ferroptosis analysis and mitochondria analysis were performed to reveal the role and underlying mechanisms of ADE in NSCLC cell lines (H460 and H1650). In vivo, xenograft model and lung metastatic model were performed to verify the effect of ADE on the growth and metastasis of NSCLC. RESULTS: In this present study, we demonstrated that treatment with ADE could inhibit cell growth and metastases through eliciting ferroptosis in vitro an in vivo. The IC50 of ADE in H460 and H1650 cells were 33.16 µM and 32.45 µM respectively. In Lewis xenografted animals, i.p. ADE repressed relative tumor growth (p < 0.01) and inhibited metastases (p < 0.01). Notably, the ferroptosis inhibitor Fer-1 abrogated the anti-tumor capacity of ADE. Induction of ferroptosis by ADE was confirmed by elevated levels of reactive oxygen sepsis (ROS), glutathione (GSH), malondialdehyde (MDA), intracellular iron content and lipid ROS reduced glutathione (GSH) accumulation (p < 0.01). Furthermore, ADE inhibited the expression of ferroptosis-related protein GPX4 and SLC7A11. Simultaneously, it also disclosed that ADE enhanced mitochondrial dysfunction, as evidenced by increased mitochondrial ROS release, mitochondrial membrane potential (MMP) depolarization, and decreased mitochondrial ATP. Most interestingly, Mito-TEMPO, a mitochondria-targeted antioxidant, rescued ADE-induced ferroptosis. CONCLUSION: Our data validated that ADE treatment could restrain proliferation and metastases of NSCLC cells through induction of ferroptosis via potentiating mitochondrial dysfunction.

RESUMEN

Objective: Regarding the effects and practical application of insulin pumps on patients with type 1 diabetes mellitus (T1DM), the real-world evidence is limited especially concerning the incidence of hypoglycemia. This study aimed to compare the efficacy of continuous subcutaneous insulin infusion (CSII) therapy with multiple daily injection (MDI) therapy on glycemic metrics evaluated by retrospective continuous glucose monitoring (CGM) in Chinese patients with T1DM. Methods: In total, 362 T1DM Chinese patients from the outpatient department of the Second Xiangya Hospital, Central South University, who underwent intensive insulin therapy and used a retrospective CGM system were included in this retrospective cross-sectional study. Comprehensive analysis of clinical and biological features and retrospective CGM derived-metrics was performed on the 362 enrolled T1DM patients who underwent CSII (n = 61) or MDI (n = 301) therapy (defined as 4 or more insulin injections per day). Results: Our findings demonstrated that patients who underwent CSII therapy, compared with those who received MDI therapy, had lower levels of hemoglobin A1c (HbA1c) and fasting blood glucose; moreover, CSII therapy was associated with better glycemic outcomes in terms of increasing time in range (TIR), decreasing time above range (TAR), and achieving CGM-associated targets of TIR ≥70% and TAR <25%. However, patients who underwent CSII therapy did not experience decreasing time below range (TBR), achieving CGM-associated targets of TBR <4%, and reduction of the risk of hypoglycemia as evidenced by comparing TBR and low blood glucose index (LBGI) between the two treatment regimens. The parameters of glycemic variability, such as standard deviation of glucose (SD), mean amplitude glycemic excursion (MAGE), and large amplitude glycemic excursion (LAGE) in T1DM patients who underwent CSII therapy outperformed. Conclusion: Our results provided further evidence that CSII therapy is safe and effective for management of Chinese T1DM patients, which was confirmed by a lower HbA1c level and better CGM-derived metrics but no demonstration of improvment in the risk of hypoglycemia. To achieve more satisfactory glycemic outcomes through the utilization of CSII therapy for Chinese T1DM patients, a strong physician-patient relationship is essential.

RESUMEN

BACKGROUND:The structure,physical and chemical properties(such as rheological properties)and biological activity of hyaluronic acid with different molecular weights are quite different.When the degradation degree of non-cross-linked hyaluronic acid is too large and the high-molecular-weight hyaluronic acid is degraded to low-molecular-weight hyaluronic acid,the properties and biological functions of the product will also change,which will affect the use of the product. OBJECTIVE:To review the mechanism of molecular weight degradation of non-cross-linked hyaluronic acid and the impacts of molecular weight degradation on the structure,rheological properties,biological activity and applications of non-cross-linked hyaluronic acid. METHODS:The first author searched the articles related to the molecular weight of hyaluronic acid collected in PubMed,CNKI database and other databases.The high-quality articles with high correlation were screened according to the inclusion and exclusion criteria.The search time was from January 2017 to December 2022.The Chinese and English search terms were"hyaluronic acid,non-cross-linked hyaluronic acid,molecular weight,degradation,structure,rheological properties,biologic activity".Finally,47 articles were included for review and analysis. RESULTS AND CONCLUSION:(1)The molecular weight of non-cross-linked hyaluronic acid is mainly degraded by specific enzymatic hydrolysis and non-specific free radical degradation.(2)The molecular weight degradation of non-cross-linked hyaluronic acid will change its structure and rheological properties,resulting in the untie of polymer network structure,the decrease of rheological properties such as viscosity and viscoelasticity,and the decrease of mechanical properties,which will eventually affect the practical application effect of the product.(3)The biological activity of non-cross-linked hyaluronic acid is molecular weight dependent,and the biological activity of different molecular weight hyaluronic acid is different.Even the same receptor combined with high-molecular-weight hyaluronic acid and low-molecular-weight hyaluronic acid will express completely opposite biological effects.(4)The degradation of molecular weights of non-cross-linked hyaluronic acid will reduce the safety and efficacy of the products,affect their service life and application performance,and ultimately influence the clinical application results.(5)Non-cross-linked hyaluronic acid has great potential as a biodegradable biomaterial in wound healing,tissue engineering,aesthetic medicine and other fields,and further research and understanding of the correlation between molecular weight degradation of non-cross-linked hyaluronic acid and bioactivity is a prerequisite for better development of wound dressings,drug delivery systems and tissue-engineered scaffolds.(6)However,there are currently few studies on the molecular weight degradation of non-cross-linked hyaluronic acid,and it is unclear how to effectively avoid the potential risks associated with the molecular weight degradation of non-cross-linked hyaluronic acid in clinical applications.(7)Therefore,a series of potential risks associated with the molecular weight degradation of non-cross-linked hyaluronic acid during its application,including the effects on its structure,properties and biological activity,and the resulting changes on the body,is one of the future directions that need to be closely investigated.

RESUMEN

Abiotic stresses substantially affect the growth and development of plants. Plants have evolved multiple strategies to cope with the environmental stresses, among which transcription factors play an important role in regulating the tolerance to abiotic stresses. Basic leucine zipper transcription factors (bZIP) are one of the largest gene families. The stability and activity of bZIP transcription factors could be regulated by different post-translational modifications (PTMs) in response to various intracellular or extracellular stresses. This paper introduces the structural feature and classification of bZIP transcription factors, followed by summarizing the PTMs of bZIP transcription factors, such as phosphorylation, ubiquitination and small ubiquitin-like modifier (SUMO) modification, in response to abiotic stresses. In addition, future perspectives were prospected, which may facilitate cultivating excellent stress-resistant crop varieties by regulating the PTMs of bZIP transcription factors.

RESUMEN

AIM:One of the important characteristics of the occurrence and development of triple-negative breast cancer(TNBC)is dysregulated cell metabolism.The aim of this study is to investigate the mechanism of pyruvate dehydrogenase E1 subunit alpha 1(PDHA1),a key enzyme component in aerobic glycolysis,affecting the proliferation,metastasis and invasion of TNBC.METHODS:(1)The expression levels of PDHA1 in breast cancer tissues and adja-cent tissues were analyzed by UALCAN database,KM-plotter database,Gene MANIA database and TCGA database.The expression of PDHA1 was compared according to tumor pathological stage,subtype classification and breast cancer bio-markers.The function of PDHA1 in TNBC was explored by gene enrichment analysis.(2)Immunohistochemistry assays were used to detect the expression of PDHA1 in human TNBC tissue and adjacent tissue samples.(3)Stable PDHA1 knockout and PDHA1 rescue TNBC MDA-MB-231 cells were constructed.The proliferation of MDA-MB-231 cells was de-tected by colony formation assay and cell counting assay.The regulatory effect of PDHA1 on the invasion and migration of MDA-MB-231 cells was detected by in vitro scratch assay and Transwell migration assay.RESULTS:Database analysis showed that the group with high PDHA1 expression in breast cancer had shorter survival and worse prognosis.In clinical specimens,the expression of PDHA1 in cancer tissues was higher than that in adjacent normal tissues.Knockout of PDHA1 inhibited the proliferation,metastasis,invasion and epithelial-mesenchymal transition of MDA-MB-231 cells.CONCLUSION:PDHA1 is overexpressed in TNBC,and it promotes cell proliferation and facilitates TNBC metastasis through the epithelial-mesenchymal transition pathway.

RESUMEN

ObjectiveTo investigate the therapeutic effect of Baihe Wuyaotang (BWT) on non-alcoholic fatty liver disease (NAFLD) and elucidate its underlying mechanism. MethodC57BL/6J mice were randomly assigned to six groups: normal control, model, positive drug (pioglitazone hydrochloride 1.95×10-3 g·kg-1), and low-, medium-, and high-dose BWT (1.3,2.5 and 5.1 g·kg-1). Following a 12-week high-fat diet (HFD) inducement, the mice underwent six weeks of therapeutic intervention with twice-daily drug administration. Body weight was monitored weekly throughout the treatment period. At the fifth week, glucose tolerance (GTT) and insulin tolerance (ITT) tests were conducted. Subsequently, the mice were euthanized for the collection of liver tissue and serum, and the subcutaneous adipose tissue (iWAT) and epididymal adipose tissue (eWAT) were weighed. Serum levels of total triglycerides (TG) and liver function indicators,such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), were determined. Histological examinations, including oil red O staining, hematoxylin-eosin (HE) staining, Masson staining, and transmission electron microscopy, were performed to evaluate hepatic lipid deposition, pathological morphology, and ultrastructural changes, respectively. Meanwhile, Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were employed to analyze alterations, at both gene and protein levels, the insulin signaling pathway molecules, including insulin receptor substrate 1/2/protein kinase B/forkhead box gene O1 (IRS1/2/Akt/FoxO1), glycogen synthesis enzymes phosphoenolpyruvate carboxy kinase (Pepck) and glucose-6-phosphatase (G6Pase), lipid metabolism-related genes stearoyl-coA desaturase-1 (SCD-1) and carnitine palmitoyltransferase-1 (CPT-1), fibrosis-associated molecules α-smooth muscle actin (α-SMA), type Ⅰ collagen (CollagenⅠ), and the fibrosis canonical signaling pathway transforming growth factor-β1/drosophila mothers against decapentaplegic protein2/3(TGF-β1/p-Smad/Smad2/3), inflammatory factors such as interleukin(IL)-6, IL-8, IL-11, and IL-1β, autophagy markers LC3B Ⅱ/Ⅰ and p62/SQSTM1, and the expression of mammalian target of rapamycin (mTOR). ResultCompared with the model group, BWT reduced the body weight and liver weight of NAFLD mice(P<0.05, P<0.01), inhibited liver lipid accumulation, and reduced the weight of white fat: it reduced the weight of eWAT and iWAT(P<0.05, P<0.01) as well as the serum TG content(P<0.05, P<0.01). BWT improved the liver function as reflected by the reduced ALT and AST content(P<0.05, P<0.01). It improved liver insulin resistance by upregulating IRS2, p-Akt/Akt, p-FoxO1/FoxO1 expressions(P<0.05). Besides, it improved glucose and lipid metabolism disorders: it reduced fasting blood glucose and postprandial blood glucose(P<0.05, P<0.01), improved GTT and ITT(P<0.05, P<0.01), reduced the expression of Pepck, G6Pase, and SCD-1(P<0.01), and increased the expression of CPT-1(P<0.01). The expressions of α-SMA, Collagen1, and TGF-β1 proteins were down-regulated(P<0.05, P<0.01), while the expression of p-Smad/Smad2/3 was downregulated(P<0.05), suggesting BWT reduced liver fibrosis. BWT inhibited inflammation-related factors as it reduced the gene expression of IL-6, IL-8, IL-11 and IL-1β(P<0.01) and it enhanced autophagy by upregulating LC3B Ⅱ/Ⅰ expression(P<0.05)while downregulating the expression of p62/SQSTM1 and mTOR(P<0.05). ConclusionBWT ameliorates NAFLD by multifaceted improvements, including improving IR and glucose and lipid metabolism, anti-inflammation, anti-fibrosis, and enhancing autophagy. In particular, BWT may enhance liver autophagy by inhibiting the mTOR-mediated signaling pathway.

RESUMEN

Staphylococcus epidermidis can exhibit both protective and opportunistic pathogenic effects on the skin: on the one hand, it suppresses pathogenic bacteria and inflammation, assists the innate immune system of the skin, and maintains homeostasis of skin microenvironment; on the other hand, it exhibits pathogenic potential. How Staphylococcus epidermidis affects human skin conditions depends not only on itself, but also on the communication among it, the host immune system, other microorganisms and environment factors. The balance of this interaction is the symbiotic homeostasis of Staphylococcus epidermidis, and when the homeostasis is disrupted, a variety of skin diseases such as acne vulgaris, atopic dermatitis, rosacea and melanoma can occur. Factors affecting the symbiotic homeostasis of Staphylococcus epidermidis include environmental conditions such as temperature, oxygen content and nutrition, antibiotics, the number of other microorganisms, microecological diversity, etc. This review summarizes recent research progress in symbiotic homeostasis of Staphylococcus epidermidis.

RESUMEN

The condition of critically ill patients changes rapidly, involving pathological changes in multiple systems and organs throughout the body. Exploring the causal relationship of mechanisms can further reveal etiology, treatment, and prognosis of diseases. However, traditional prospective studies in the field of critical care are still subject to numerous limitations. As an emerging research method, Mendelian randomization (MR) analysis uses genetic variation to provide causal evidence for instrumental variables, which is expected to provide clues in critical diseases. This article systematically describes the research progresson the application of MR analysis in critical care medicine from four aspects: the principle of MR analysis, the difference between MR analysis and randomized controlled trial (RCT), the use of MR analysis in the field of critical illness, and the possible methods of application, aiming to provide possible directions for the research in this field.

RESUMEN

Soft tissue is an indispensable tissue in human body. It plays an important role in protecting the body from external physical, chemical or biological factors. Mild soft tissue injuries can self-heal, while severe soft tissue injuries may require related treatment. Natural polymers (such as chitosan, hyaluronic acid, and collagen) and synthetic polymers (such as polyethylene glycol and polylactic acid) exhibit good biocompatibility, biodegradability and low toxicity. It can be used for soft tissue repairs for antibacterial, hemostatic and wound healing purposes. Their related properties can be enhanced through modification or preparation of composite materials. Commonly used soft tissue repairs include wound dressings, biological patches, medical tissue adhesives, and tissue engineering scaffolds. This study introduces the properties, mechanisms of action and applications of various soft tissue repair medical materials, including chitosan, hyaluronic acid, collagen, polyethylene glycol and polylactic acid, and provides an outlook on the application prospects of soft tissue repair medical materials and products.

RESUMEN

Renal hematuria is caused by glomerular damage and basement membrane rupture due to coagulation dysfunction, ischemia and hypoxia, and immune function damage, resulting in red blood cells exuding through glomerular filtration membrane and excreting with urine. It is mainly manifested as microscopic and macroscopic hematuria. Among them, microscopic hematuria is characterized by microscopic urine sediment examination, there are three or more red blood cells per high-power microscopic field. Traditional Chinese medicine (TCM) believes that the pathogenesis of renal hematuria always belongs to ''asthenia in origin and sthenia in superficiality'', and ''asthenia in origin'' is caused by the deficiency of the three viscera of the lung, spleen, and kidney, while ''sthenia in superficiality'' is caused by the combination of dampness and blood stasis and the external disturbance of wind pathogens. The key pathogenesis features are ''deficiency, dampness, heat, blood stasis, and wind''. After consulting the TCM literature related to renal hematuria, the author found that the common syndrome types of renal hematuria in clinical practice were the deficiency of both Qi and Yin, the deficiency of both Yin and fire, the unsteadiness of kidney Qi, the deficiency of spleen and kidney Yang, the wind heat hurting the collateral, the dampness-heat blocking, and the blood stasis and internal resistance. The commonly used classical or temporal prescriptions included Shenqi Dihuangtang(参芪地黄汤), Zhibai Dihuangtang(知柏地黄汤), Wubi Shanyaowan(无比山药丸), Jisheng Shenqiwan(济生肾气丸), Sishenwan(四神丸), Yinqiaosan(银翘散), Bazhengsan(八正散), Sanrentang(三仁汤), Xuefu Zhuyutang(血府逐瘀汤), Danggui Shaoyaosan(当归芍药散), Xiaoji Yinzi(小蓟饮子), Buzhong Yiqitang(补中益气汤), et al. Self prepared prescriptions mainly include Tongluo Ningxue prescription (通络宁血方), Qingre Zhixue prescription( 清热止血方) and Wuteng Tongluo drink (五藤通络饮). The traditional Chinese medicine is commonly used for the treatment of Xueniaoling granules(血尿灵冲剂), Xueniaoan capsules(血尿安胶囊), Ningmitai capsules(宁泌泰胶囊), Huangkui capsules(黄葵胶囊) and Yishen nixuexiao granules(益肾溺血消颗粒), which constantly enriched the treatment of renal hematuria. The combination of TCM and western medicine has obvious advantages. The treatment of renal hematuria in clinical practice often combines with modern medical methods, which has a good therapeutic effect on the improvement of symptoms and indicators of renal hematuria. At present, many doctors have made in-depth exploration on the etiology, pathogenesis, and clinical treatment of renal hematuria, but few scholars have made detailed induction and collation in recent years. Therefore, the author has collated the clinical data on the treatment of renal hematuria with TCM in the past ten years, and reviewed it from the aspects of etiology, pathogenesis, and clinical research, to provide useful references for clinical intervention and delay the progress of renal disease.

RESUMEN

Photoplethysmography (PPG) is often affected by interference, which could lead to incorrect judgment of physiological information. Therefore, performing a quality assessment before extracting physiological information is crucial. This paper proposed a new PPG signal quality assessment by fusing multi-class features with multi-scale series information to address the problems of traditional machine learning methods with low accuracy and deep learning methods requiring a large number of samples for training. The multi-class features were extracted to reduce the dependence on the number of samples, and the multi-scale series information was extracted by a multi-scale convolutional neural network and bidirectional long short-term memory to improve the accuracy. The proposed method obtained the highest accuracy of 94.21%. It showed the best performance in all sensitivity, specificity, precision, and F1-score metrics, compared with 6 quality assessment methods on 14 700 samples from 7 experiments. This paper provides a new method for quality assessment in small samples of PPG signals and quality information mining, which is expected to be used for accurate extraction and monitoring of clinical and daily PPG physiological information.

RESUMEN

T 3 rectal cancer patients are a heterogeneous group of populations. T 3 stage patients with good prognosis are similar to their T 2 stage counterparts, and T 3 stage patients with poor prognosis are similar to T 4 stage counterparts. Although small sample clinical trials, meta-analyses and retrospective analyses have been conducted, clinical guidelines are not completely consistent with the definition of risk factors and treatment recommendations for this group of populations. At present, the treatment strategy for T 3 rectal cancer is still controversial, especially the application of perioperative radiotherapy. In this article, current application status and research progress in perioperative chemoradiotherapy for T 3 rectal cancer were reviewed.

RESUMEN

The incidence of lateral lymph node metastases (LLN) of locally advanced middle-low rectal cancer (II-Ⅲ stage) is high and clinical prognosis is poor. At present, the treatment plan of LLN is controversial between the East and the West. Scholars from the East represented by Japan believe that LLN is a regional disease. Lateral pelvic lymph node dissection (LPLND) is recommended when the tumor is located under the peritoneal reflection and invades into the muscular layer, regardless of the presence or absence of LLN. However, European and American scholars believe that LLN is a systemic disease and recommend neoadjuvant chemoradiotherapy (nCRT) combined with total mesorectal excision (TME). Nevertheless, recent studies have found that neither nCRT nor LPLND can significantly reduce the locoregional recurrence (LR) rate in patients with LLN, while nCRT combined with LPLND yields better prognosis. Some studies have also demonstrated that increasing the radiotherapy dose of metastatic lymph nodes can improve the local control rate. In this article, current treatment status of this population was reviewed, aiming to provide a basis for clinical treatment.
