Post-stroke fatigue, hope and discharge readiness: A cross-sectional survey.

AIMS AND OBJECTIVES: To explore the relationships among post-stroke fatigue, hope and discharge readiness in stroke patients, and to determine whether hope mediates the relationship between post-stroke fatigue and discharge readiness. BACKGROUND: In stroke patients, inadequate discharge readiness has been found to correlate with higher readmission and mortality rates. Although previous qualitative studies have confirmed the impact of fatigue on discharge readiness, few studies explore the impact of post-stroke fatigue and hope on discharge readiness of stroke patients. Consequently, the current research on this relationship and its underlying mechanisms is still quite limited. DESIGN: Cross-sectional study. METHODS: Data were collected from 340 stroke patients. The research tools included demographic and disease characteristics, Discharge Readiness Assessment Scale for Stroke, Neurological Fatigue Index for Stroke and Herth Hope Index. The STROBE checklist was used to guide the presentation of this study. RESULTS: Discharge readiness was negatively correlated with post-stroke fatigue and positively correlated with hope. Additionally, post-stroke fatigue was negatively correlated with hope. Post-stroke fatigue had a direct negative effect on discharge readiness, and it can also generate indirect effects through hope. Hope was the partial mediator between post-stroke fatigue and discharge readiness, explaining 55.8% of the total effect. CONCLUSION: Discharge readiness of this population can be improved by reducing post-stroke fatigue and increasing hope. Therefore, effective management of post-stroke fatigue and hope will help improve discharge readiness. RELEVANCE TO CLINICAL PRACTICE: It is recommended that nursing staff should monitor the occurrence and development of post-stroke fatigue in stroke patients, dynamically evaluate the patient's level of hope, and pay attention to the important role of positive psychological qualities in the outcome of discharge. If medical staff can formulate corresponding intervention measures based on the influence path of discharge readiness, then the discharge readiness of stroke patients can be improved.

Blood routine risk factors for coronary artery aneurysm in infants younger than 8 months with Kawasaki disease.

OBJECTIVE: The aims of this study were to characterize the evolution of routine blood values within the first 10 days of illness and coronary artery outcome in infants < 8 months with Kawasaki disease (KD) and to identify risk factors for coronary artery aneurysm (CAA). METHODS: Laboratory data, clinical features and coronary artery outcomes from 78 infants < 8 months old and 86 patients between 8 months and 7 years old were retrospectively analyzed. Logistic regression analysis was conducted to evaluate the potential risk factors for CAA. RESULTS: Infants < 8 months old were more likely to present with incomplete KD (37.2% vs 4.7%, P < 0.001), erythema and induration at the BCG inoculation site (24.4% vs 3.5%, P < 0.001) and CAA (47.4% vs 15.1%, P < 0.001) even with timely diagnosis and treatment with intravenous immunoglobulin (IVIG) compared with patients ≥8 months old. Clinical feature related to diagnostic criteria for KD including bilateral conjunctival injection, oral changes, unilateral cervical lymphadenopathy and extremity changes were less common in the younger group. During the acute phase, the percentage neutrophils and neutrophil to lymphocyte ratio [NLR] peaked on median illness day 3, followed by white blood cell (WBC) and CRP on median illness day 4, hemoglobin on median illness day 7 and platelet count on median illness day 9. CAA occurred on median illness day 6 and regressed on median illness day 28. Multivariate logistic regression analysis revealed that the peak percentage neutrophils (odds ratio [OR] per 0.1: 1.597, 95% confidence interval [CI]: 1.041-2.452, P = 0.032) and the peak platelet count (OR per 10 × 109/L: 1.029, 95% CI: 1.004-1.055, P = 0.024) were independent risk factors for CAA. Hemoglobin on the 5th day was associated with persistent CAA at 1 year after KD onset. CONCLUSION: Factors associated with CAA include a high peak percentage neutrophils, increased peak platelet count, and reduced hemoglobin within 4-6 days during the acute phase of KD. Therefore, this population should receive primary therapy with IVIG and adjunctive anti-inflammatory medications.

Predictors for lower urinary tract symptoms in patients underwent radical prostatectomy: implications for postoperative nursing care.

AIMS AND OBJECTIVES: The aim of this study was to evaluate the risk factors for lower urinary tract symptoms in prostate cancer patients underwent radical prostatectomy, thus providing therapeutic evidence for post-operative nursing. BACKGROUND: Prostate cancer is one of the most commonly diagnosed male malignancy in recent years. With surgical treatments, patients with prostate cancer indeed have satisfying survival rate. However, the presence of postprostatectomy lower urinary tract symptoms which affect quality of life significantly is more worthy of attention. DESIGN: Patients underwent surgical therapies were followed up and the symptoms were recorded. METHODS: A total of 65 prostate cancer patients underwent radical prostatectomy from January 2019 to October 2020, and pathologically diagnosed with prostate cancer were enrolled in our study. These patients were followed up 3 months after surgery and their medical records were retrospectively collected and analysed. Results were reported according to the STROBE Statement. RESULTS: The incidence of post-operative lower urinary tract symptoms at 3 months after surgery is similar to that of pre-operation. Univariate and multivariate analyses revealed that the independent risk factor for postprostatectomy lower urinary tract symptoms is body mass index, whereas pelvic floor muscle exercise is a protective factor. CONCLUSIONS: The incidence of postprostatectomy lower urinary tract symptoms is non-negligible, which significantly affects quality of life. Body mass index is found as an independent risk factor for postprostatectomy lower urinary tract symptoms, while pelvic floor muscle exercise is a strong protector. RELEVANCE TO CLINICAL PRACTICE: Patients with prostate cancer would benefit from post-operative pelvic floor muscle exercise. These findings contribute to tailor post-operative nursing strategy.

Silencing of long noncoding RNA XIST attenuated Alzheimer's disease-related BACE1 alteration through miR-124.

Alzheimer's disease (AD) is a chronic progressive neurodegenerative disorder. However, its pathogenetic mechanism is still poorly understood. An increasing number of studies have evidenced the important role of long noncoding RNAs (lncRNAs) in AD. The aim of the current study was to investigate the effect and molecular mechanism of the lncRNA X-inactive specific transcript (XIST) in AD. Bilateral common carotid artery occlusion (2VO) was used to induce an AD model in mice. Hydrogen peroxide (H2 O2 ) was used to induce an AD model in N2a cells. The lncRNA XIST, miR-124, and BACE1 messenger RNA expression levels were detected by a real-time polymerase chain reaction. The BACE1 protein expression level was detected by western blot and immunofluorescence assay. The Aß1-42 expression level was detected using an enzyme-linked immunosorbent assay kit. The expression level of lncRNA XIST was significantly upregulated in AD models, both in vivo and in vitro. Silencing of lncRNA XIST negatively regulated miR-124 and positively regulated BACE1 expression in N2a cells, which is attenuated by cotransfection of anti-miR-124 oligodeoxyribonucleotide (AMO-124). Silencing of lncRNA XIST reversed the effect of H2 O2 on miR-124, BACE1, and Aß1-42 expression in N2a cells, which was reversed by cotransfection of AMO-124. Silencing of lncRNA XIST attenuated AD-related BACE1 alteration through miR-124. LncRNA XIST may be a new potential target for the treatment of AD.

Overexpression of rice aquaporin OsPIP1;2 improves yield by enhancing mesophyll CO2 conductance and phloem sucrose transport.

Aquaporins are involved in CO2 transport from the leaf intercellular air space to the chloroplast, which contributes to CO2 assimilation. However, the mechanism of CO2 transport by rice (Oryza sativa L.) aquaporins is unknown. Here, we investigated the function of the aquaporin OsPIP1;2 in CO2 diffusion-associated photosynthesis and phloem sucrose transport. Moreover, the grain yield of rice lines overexpressing OsPIP1;2 was determined. OsPIP1;2 was localized to the plasma membrane and the relative expression of OsPIP1;2 was approximately 5-fold higher in leaves in the presence of an elevated CO2 concentration. Overexpression of OsPIP1;2 increased mesophyll conductance by approximately 150% compared with wild-type (WT) rice. The OsPIP1;2-overexpressing lines had higher biomass than the WT, possibly due to increased phloem sucrose transport. In addition, the grain yield of OsPIP1;2-overexpressing lines was approximately 25% higher than that of the WT in three-season field experiments, due to the increased numbers of effective tillers and spikelets per panicle. Our results suggest that OsPIP1;2 modulates rice growth and grain yield by facilitating leaf CO2 diffusion, which increases both the net CO2 assimilation rate and sucrose transport.

Oxidation rate of magnesium sulfite catalyzed by cobalt ions.

Oxidation of magnesium sulfite is important for recycle of byproduct in the magnesium desulfurization. The oxidation rate of magnesium sulfite, prepared by vacuum evaporation method, was investigated in a bubbling tank in presence of transition metal catalysts, which shows cobalt is the most effective. The general reaction orders with respect to cobalt, magnesium sulfite, and oxygen are 0.44, 0, and 0.46, respectively, and the apparent activity energy is 17.43 KJ·mol. The catalytic performance of cobalt compared with other metals was also analyzed employing the ion potential theory. Integrated with the three-phase reaction model, we inferred that the general oxidation rate of magnesium sulfite is controlled by mass transfer of oxygen. Further, the intrinsic kinetics was predicted, indicating that the reaction orders with respect to cobalt and oxygen are 1.0 and 0, respectively. The results are helpful for the recycle of magnesium sulfite in magnesia desulfurization.

Investigation of the effects of graded models on the biomechanical behavior of a bone-dental implant system under osteoporotic conditions.

OBJECTIVE: To investigate the effects of graded models on the biomechanical behavior of a bone-implant system under osteoporotic conditions. Methodology : A finite element model (FEM) of the jawbone segments with a titanium implant is used. Two types of models (a graded model and a non-graded model) are established. The graded model is established based on the graded variation of the elastic modulus of the cortical bone and the non-graded model is defined by homogeneous cortical bone. The vertical and oblique loads are adopted. The max von Mises stresses and the max displacements of the cortical bone are evaluated. RESULTS: Comparing the two types of models, the difference in the maximum von Mises stresses of the cortical bone is more than 20%. The values of the maximum displacements in the graded models are considerably less than in the non-graded models. CONCLUSIONS: These results indicate the significance of taking into account the actual graded properties of the cortical bone so that the biomechanical behavior of the bone-implant system can be analyzed accurately.

Research on the degree of coupling of the Internet development level and agricultural--Ecological efficiency based on 2009-2018 data from 13 major grain-producing areas in China.

Agricultural informatization and agricultural green development are important components of modern agricultural development, and coordination between the two is an important foundation for achieving sustainable agricultural development. This paper uses data from the 13 major grain producing areas in China from 2009 to 2018 to analyze the coordination of the Internet development level and the agricultural ecological-efficiency, and it further investigates the degree of coupling and coordination between the two. The results of theis study are as follows.(1) The Internet development level of China's 13 main grain production areas has been continuously improving. The average Internet penetration rate increased from 0.25 in 2008 to 0.54 in 2018. (2) The agricultural ecological efficiency of China's main grain production areas has gradually improved. The average value of agricultural ecological efficiency increased from 0.45 in 2009 to 0.79 in 2018. (3) The Internet development level in China's main grain production areas and the continuous improvement of coordination and degree of coupling of the agricultural ecological efficiency show that the interaction between them has led to continuous improvements in the agricultural informatization development and agricultural green development. However, the coordination between the two still has significant room for growth, and there is a certain gap between the different regions.

The main property was cold, the main taste was sweet, the main meridian was spleen meridian, and the main efficacy was heat clearing and detoxification. Three types of high-frequency drugs could be obtained by clustering analysis, namely, Ginseng Radix et Rhizoma-Astragali Radix-Angelicae Sinensis Radix-Rhei Radix et Rhizoma, Scutellariae Radix-Paeoniae Radix alba-Glycyrrhizae Radix et Rhizoma, Trichosanthis Fructus-Olibanum-Gleditsiae Spina. Through correlation analysis of high-frequency drugs, it was found that there was a great correlation between Astragali Radix and Paeoniae Radix alba, Angelicae Sinensis Radix, Glycyrrhizae Radix et Rhizoma, Ginseng Radix et Rhizoma.Conclusions:The pathogenesis of acute mastitis in Pu Ji Fang is mainly damp-heat toxin and blood stasis, and deficiency of qi and blood. The treatment for strengthening healthy qi focuses on tonifying qi and blood of the liver and spleen, while the treatment for eliminating pathogenic factors focuses on removing dampness, clearing heat and toxin, resolving phlegm, dispersing stasis and removing blood stasis. In addition, according to the condition, the treatment will be increased or decreased with the disease.

Multi-feature fusion method for medical image retrieval using wavelet and bag-of-features.

Color, texture, and shape are the common features used for the retrieval systems. However, many medical images have a spot of color information. Therefore, the discriminative texture and shape features should be extracted to obtain a satisfied retrieval result. In order to increase the credibility of the retrieval process, many features can be combined to be used for medical image retrieval. Meanwhile, more features require more processing time, which will decrease the retrieval speed. In this paper, wavelet decomposition is adopted to generate different resolution images. Bag-of-feature, texture, and LBP feature are extracted from three different-level wavelet images. Finally, the similarity measure function is obtained by fusing these three types of features. Experimental results show that the proposed multi-feature fusion method can achieve a higher retrieval accuracy with an acceptable retrieval time.

Exploration of “Burnt Needle” and “Red-hot Needling” in the Inner Canon of Yellow Emperor （《黄帝内经》） / 中医杂志

“Burnt needle” and “red-hot needling” are both mentioned in the Inner Canon of Yellow Emperor （《黄帝内经》）， although they possess distinct characteristics and are not identical. Subsequent generations have erroneously employed them as interchangeable with “fire needles”， which is an incorrect designation. This article mostly relies on the original text of the Inner Canon of Yellow Emperor and provides an interpretation of their significances as follows： “burnt needle” is a broad phrase referring to needles that have been intentionally burned in order to heat them； the term “burnt needle and rapid needling” can be more accurately described as “the act of rapidly puncturing with a needle， without burning the needle if the disease exhibits hot characteristics， but requiring burning if the disease exhibits cold characteristics， and it is appropriate to puncture rapidly before burning the needle”. “Red-hot needling” refers to the process of first burning the needle and then puncturing with it， which is specific. This paper clarified the origins and differences among burnt needles， red-hot needling， red-hot needle， burning needle， warm needles and fire needle， pointing out the doctrinal diagnostic and therapeutic system based on “burnt Needle” and “red-hot needling”， can be a track for the integration of acupuncture and moxibustion.

OBJECTIVE To investigate the preferences of patients who underwent solid organ transplantation regarding therapeutic drug monitoring （TDM） of mycophenolic acid （MPA） and explore the factors influencing patients’ decision-making process， so as to provide support for the development of individualized medication guidelines for MPA and improvement of clinical decision-making. METHODS The cross-sectional study was used to design the questionnaire on the patients’ preferences to accept MPA TDM， and involved patients who underwent solid organ transplantation and received MPA treatment at two tertiary hospitals in Beijing from April 14， 2022， to June 27， 2022. The Likert 5-level scoring method was used to score the patients’ preferences to accept MPA TDM， the influencing factors and their correlation of the patients’ preferences to accept MPA TDM were analyzed by Pearson correlation analysis and binary Logistic regression analysis， and the nonparametric test and chi-square test were used to rank and analyze the consistency of the factors affecting patients’ preference decision. RESULTS A total of 140 questionnaires were collected， and the effective recovery rate was 77.35%. The average preference score of 140 patients to receive MPA TDM was （4.01±0.65）， and the overall preference value was high. There were 116 （82.86%） patients agreed or strongly agreed with MPA TDM. Significant differences were observed in preference scores between patients who had previously undergone MPA TDM and those who had never undergone it （[ 4.30±0.53） scores vs. （3.80±0.65） scores， P＜0.001]. Additionally， patients’ preference scores were significantly influenced by their understanding level and attention level （P＜0.001）. The ranking of factors contributing to decision-making exhibited consistency （P＜0.001）. The factors were ranked in descending order of clinical efficacy， safety， comfortability， economy and time cost. CONCLUSIONS The patients who underwent solid organ transplantation hold high preferences towards MPA TDM. The primary factors influencing their decisions are their prior experience， understanding level， and attention level.

Relationship between coping style and psychological distress in stroke patients： the pathway of resourcefulness / 四川精神卫生

BackgroundStroke patients commonly experience varying degrees of psychological distress. Previous studies have shown that the psychological distress of stroke patients is closely related to their coping styles and resourcefulness. However， the path of wisdom in coping style and psychological pain of stroke patients is still unclear. ObjectiveTo explore the path of resourcefulness between coping styles and psychological distress in stroke patients， so as to provide insights for interventions targeting psychological distress. MethodsA total of 350 patients who met the diagnostic criteria for stroke according to the Diagnostic Criteria of Cerebrovascular Diseases in China （version 2019） and were admitted to the neurology departments of two tertiary grade-A hospitals in Luzhou City from January to May 2023 were selected as the research subjects. Basic information was collected using a self-designed questionnaire， and Resourcefulness Scale （RS）， Medical Coping Mode Questionnaire （MCMQ） and Distress Thermometer （DT） were used for assessment. Pearson correlation analysis was conducted to examine the correlation between the scores of each scale. Model 4 of the Process 3.4.1 program was employed to analyze the path of resourcefulness between coping styles and psychological distress， and the Bootstrap method was used to test the mediation effects. ResultsThe DT score showed a negative correlation with the confrontation and RS scores （r=-0.581， -0.716， P<0.01）， and a positive correlation with the avoidance and resignation scores （r=0.432， 0.758， P<0.01）. The confrontation score was positively correlated with RS score （r=0.700， P<0.01）， while the avoidance and resignation scores were negatively correlated with RS score （r=-0.460， -0.566， P<0.01）. Resourcefulness might serve as a mediating path between confrontation， avoidance， resignation， and psychological distress， with the effect value of -0.359， 0.203 and 0.183， accounting for 81.78%， 62.65% and 27.07% of the path effect， respectively. ConclusionThe coping styles of stroke patients can directly affect their psychological distress， and can also indirectly influence it through resourcefulness. Resourcefulness may play a mediating role between coping styles and psychological distress. ［Funded by Health Humanities Research Center， Zigong Key Research Base for Philosophy and Social Sciences （number， JKRWY22-27）］

Effect of Early Intervention of Yishen Huazhuo Prescription on Learning and Memory of Accelerated Aging SAMP8 Mice and Its Mechanism / 中国实验方剂学杂志

ObjectiveTo investigate the impact of early intervention with Yishen Huazhuo prescription （YHP） on the learning and memory of accelerated aging model mice， as well as its underlying mechanism. MethodForty-eight 3-month-old male SAMP8 mice were randomly assigned into four groups， including the model group， low-dose YHP group， high-dose YHP group， and donepezil group. Additionally， 24 SAMR1 mice of the same age were divided into a control group and a YHP treatment control group， each consisting of 12 mice. The YHP groups received YHP at doses of 6.24 g·kg-1 and 12.48 g·kg-1， while the donepezil group was treated with donepezil at a dose of 0.65 mg·kg-1. The model group and control groups were given physiological saline. The mice were gavaged once daily for a duration of four weeks. Spatial learning and memory abilities of mice were assessed using the Morris water maze test. Immunofluorescence staining was employed to evaluate neuronal density as well as expression levels of M1 microglial （MG） polarization marker inducible nitric oxide synthase （iNOS） and M2 MG polarization marker arginase-1 （Arg-1） in the hippocampus region. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of pro-inflammatory factor interleukin 1β （IL-1β） and anti-inflammatory factor transforming growth factor-β1 （TGF-β1）. Furthermore， Western blot analysis was conducted to determine expressions of amyloid β peptide1-42 （Aβ1-42） along with triggering receptor expressed on myeloid cells 2 （TREM2）/nuclear factor kappa B （NF-κB） signaling pathway-related proteins TREM2， phospho （p）-NF-κB p65， and phospho-inhibitory kappa B kinase β （IKKβ） in the hippocampus. ResultCompared with the control group， the model group exhibited a significantly prolonged escape latency （P<0.01）， a significant reduction in neuron-specific nuclear protein （NeuN） expression in the hippocampus， a significant increase in iNOS expression in MG， and a significant decrease in Arg-1 expression. The serum IL-1β content was significantly increased， while the TGF-β1 content was significantly decreased. Additionally， there was a significant decrease in TREM2 expression in the hippocampus and significant increases in p-NF-κB p65， p-IKKβ， and Aβ1-42 expressions （P<0.05， P<0.01）. However， no significant changes were observed in escape latency， times of crossing the platform， and hippocampal NeuN expression in the YHP treatment control group. Conversely， iNOS expression in MG as well as the hippocampal p-NF-κB p65， p-IKKβ， and Aβ1-42 expressions were significantly decreased. Furthermore， TREM2 expression was significantly increased （P<0.05， P<0.01）. In comparison to the model group， the low-dose YHP group showed a significantly shortened escape latency and an increased number of crossing the platform （P<0.05， P<0.01）. In the high-dose YHP group， the escape latency was significantly shortened （P<0.05）. In the low-dose YHP group， high-dose YHP group， the expression of NeuN in the hippocampus was significantly increased， the expression of iNOS in MG was significantly decreased， and the expression of Arg-l was significantly increased. The serum IL-1β content was significantly decreased， while the TGF-β1 content was significantly increased. Furthermore， the expression of TREM2 in the hippocampus was significantly increased， and the expressions of p-NF-κB p65， p-IKKβ， and Aβ1-42 were significantly decreased （P<0.01）. ConclusionEarly YHP intervention may promote the transformation of hippocampal MG from M1 to M2 by regulating the TREM2/NF-κB signaling pathway， reduce the release of neuroinflammatory factors， protect hippocampal neurons， and reduce the deposition of Aβ1-42， and finally delay the occurrence of learning and memory decline in SAMP8 mice.

Mechanism of Sanhuang Xiexintang in Protecting Stress Gastric Ulcer in Rats / 中国实验方剂学杂志

ObjectiveTo explore the molecular mechanism of Sanhuang Xiexintang （SHXXT） in protecting stress gastric ulcer （SGU） in rats through network pharmacology， molecular docking， and animal experiments. MethodThe active ingredients and corresponding targets in SHXXT were collected and screened from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， Traditional Chinese Medicine Information Database （TCMID）， Bioinformation Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine （BATMAN-TCM）， and Swiss Target Prediction database. SGU-related targets were screened from the Online Mendelian Inheritance in Man （OMIM）， Therapeutic Target Database （TTD）， GeneCards database， and PharmGKB database. Herbal-ingredient-target （H-C-T） network was constructed by using Cytoscape 3.9.1 software. Protein-protein interaction （PPI） of drug and disease intersection targets was analyzed by using the Protein Interaction Platform （STRING） database. Gene ontology （GO） enrichment analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway analysis were conducted through the Database for Annotation Visualization and Integrated Discovery （DAVID）. The active ingredients and key targets were validated using AutodockVina 1.2.2 molecular docking software， and the experimental results were further validated through animal experiments. ResultThe 55 active ingredients were screened， and 255 potential target genes for SHXXT treatment of SGU were predicted. The PPI analysis showed that protein kinase B （Akt）， phosphatase and tensin homolog deleted on chromosome ten （PTEN）， tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and cyclooxygenase-2 （COX-2） are the core targets of SHXXT for protecting SGU. GO and KEGG analyses showed that SHXXT may affect the development of SGU by regulating various biological processes such as the phosphoinositide 3-kinase （PI3K）/Akt signaling pathway and inflammatory processes. The molecular docking results showed that both the active ingredients and key targets had good binding ability. Animal experiments showed that compared with the blank group， the ulcer index （UI） of the model group was significantly increased （P<0.01）， and the serum levels of TNF-α and IL-1β significantly increased （P<0.01）. The phosphorylation level of PTEN in gastric mucosal tissue was significantly down-regulated （P<0.05）. The phosphorylation levels of PI3K， Akt， and nuclear factor kappa-B （NF-κB） were significantly up-regulated （P<0.05）. Compared with the model group， the UI of the treatment group was significantly reduced （P<0.01）， and the serum levels of TNF-α and IL-1β were significantly reduced （P<0.01）. The phosphorylation level of PTEN in gastric mucosal tissue was significantly up-regulated （P<0.01）， and the phosphorylation levels of PI3K， Akt， and NF-κB were significantly downregulated （P<0.01）. ConclusionThe application of network pharmacology prediction， molecular docking simulation， and animal experimental validation confirms that SHXXT regulates the PI3K/Akt/NF-κB signaling pathway to regulate the inflammatory response of rats and thus protects the gastric mucosa of SGU rats.

Effect of Xiaoxuming decoction on OGD/R-induced synaptic plasticity in HT22 cells / 中国病理生理杂志

AIM:To explore the protective effect of Xiaoxuming decoction(XXMD)on synaptic plasticity in the context of cerebral ischemia-reperfusion injury following ischemic stroke.METHODS:An oxygen-glucose depriva-tion/reoxygenation(OGD/R)model was employed in vitro using mouse hippocampal neurons(HT22 cells)to simulate ischemia-reperfusion injury.Cell viability was assessed using a CCK-8 assay to determine the optimal XXMD concentra-tion.The HT22 cells were divided into two groups:control and model(OGD/R).Cellular morphological changes were ob-served using an inverted microscope.The levels of IL-1β,IL-6 and TNF-α in the supernatant were quantified by ELISA.Ultrastructural changes were examined by transmission electron microscopy.Immunofluorescence staining was used to de-tect neuron markers NeuN and synaptic proteins NF200 and MAP2.The protein levels of NF200 and MAP2 were analyzed by Western blot.RESULTS:The highest cell survival rate occurred at an XXMD concentration of 100 mg/L(P<0.05).Compared with control group,the cells in model group exhibited round shape and shrinkage,mitochondrial swelling or vacuolization,and a marked decrease in survival rate.There were significant increases in IL-1β,IL-6 and TNF-α levels(P<0.05).Immunofluorescence intensity and protein levels of NeuN,NF200 and MAP2 were notably reduced(P<0.05).Treatment with XXMD improved cell morphology,ultrastructure and survival rate(P<0.05),and decreased in-flammatory factor levels(P<0.05).Compared with model group,the cells in OGD/R+XXMD group showed significantly increased immunofluorescence intensity and protein levels of NeuN,NF200 and MAP2(P<0.05).CONCLUSION:Xiaoxuming decoction may mitigate OGD/R-induced injury,potentially by inhibiting inflammatory responses and enhanc-ing synaptic plasticity.

Research advances in rivaroxaban in the treatment of portal vein thrombosis in liver cirrhosis / 临床肝胆病杂志

Portal vein thrombosis (PVT) is one of the common complications of liver cirrhosis and is associated with the poor prognosis of liver disease. Rivaroxaban, a novel direct oral anticoagulant, exerts an antithrombotic effect by directly acting on the active center of factor Xa to inhibit the generation of thrombin, and it is a new choice for long-term anticoagulant treatment of PVT in liver cirrhosis with the advantages of direct oral administration and no need for international normalized ratio (INR) monitoring. In recent years, more and more clinical studies have shown that rivaroxaban is relatively safe and effective in the treatment of PVT in liver cirrhosis; however, there is still little experience in the application of rivaroxaban in the treatment of PVT in liver cirrhosis in the current clinical practice, and individualized medication regimen remains to be clarified. This article reviews the research advances in rivaroxaban in the treatment of PVT in liver cirrhosis, in order to provide new ideas for the clinical treatment of PVT in liver cirrhosis.

Anti-colorectal Cancer Mechanism of Zuojinwan and Its Main Monomer Components： A Review / 中国实验方剂学杂志

Zuojinwan is a classic Chinese medicine prescription recorded in the Danxi's Experiential Therapy， with Coptidis Rhizoma and Euodiae Fructus in a ratio of 6 ∶ 1. It can treat symptoms such as liver fire hypochondriac pain， stomach duct pain， vomiting， and acid swallowing. There are many pharmacological studies on Zuojinwan in modern times， especially in the digestive tract， but the prescription also has its unique effect on digestive tract cancer， and its anti-tumor studies mainly focus on colorectal cancer and gastric cancer. Colorectal cancer is the third most common type of cancer in the world and the second deadliest malignancy. At present， a number of studies have shown that the basic pharmacological studies of anti-colorectal cancer by Zuojinwan include the proliferation， apoptosis， invasion， energy metabolism， epigenetics， and drug resistance of colorectal cancer. Alkaloids are the main active ingredients of Zuojinwan， such as berberine， evodiamine， coptisine， palmatine， and rutaecarpine. Compared with the effect of Zuojinwan on colorectal cancer， studies on the effect of berberine and evodiamine on tumor angiogenesis， tumor-promoting inflammation， and intestinal flora are carried out， except the studies on the resistance of berberine and the effect of evodiamine on energy metabolism. In addition， coptisine， palmatine， and rutaecarpine can regulate the proliferation， apoptosis， and metastasis of colorectal cancer cells， the proliferation and apoptosis of colorectal cancer cells， tumor-promoting inflammatory response， and the proliferation， migration， and invasion of colorectal cancer cells， respectively. Moreover， other studies have shown that the combination of berberine and evodiamine can have a synergistic effect on the growth， migration， and invasion of colorectal cancer cells and can reduce the cardiac toxicity induced by evodiamine. Therefore， this paper summarizes the studies on the anti-colorectal cancer mechanism of Zuojinwan and its main monomer components in recent years， so as to provide a theoretical basis for future clinical research and development of new high-efficiency and low-toxicity anti-colorectal cancer drugs and lay a solid foundation for clinical practice.
