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.

Objective:To analyze the medication characteristics and the rules of prescription for the treatment of acute mastitis in Puji Fang; To provide reference for the clinical treatment of acute mastitis in modern TCM. Methods:Prescriptions of the chapters of " Ruyong" and " Duru" contained in Pu Ji Fang? Fu Ren Zhu Ji Men were screened, and the prescription data were analyzed by using the ancient and modern medical record cloud platform V2.3.5 for drug frequency, properties, tastes, meridian tropism, and efficacy. Clustering analysis of high-frequency drugs and analysis of association rules were performed. Results:A total of 141 prescriptions were included, with 201 kinds of Chinese materia medica. The top ten drugs with the high frequency of use were Glycyrrhizae Radix et Rhizoma, Paeoniae Radix alba, Rhei Radix et Rhizoma, Angelicae Sinensis Radix, Astragali Radix, Olibanum, Trichosanthis Fructus, Ginseng Radix et Rhizoma, Scutellariae Radix, Gleditsiae Spina. 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.

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.

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.

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）］

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.

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.

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.

Efficacy and safety of LY01005 versus goserelin implant in Chinese patients with prostate cancer: A multicenter, randomized, open-label, phase III, non-inferiority trial / 中华医学杂志(英文版)

BACKGROUND@#LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.@*METHODS@#We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.@*RESULTS@#On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).@*CONCLUSION@#LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT04563936.

Eosinophilic gastroenteritis: Pathogenesis, diagnosis, and treatment / 中华医学杂志(英文版)

Eosinophilic gastroenteritis (EGE) is a gastrointestinal disorder of unclear etiology that is characterized by eosinophilic infiltration of the stomach and small intestine, and consists of mucosal, muscular, and serosal subtypes. Eosinophilic infiltration of the gastrointestinal tract is a fundamental histopathological characteristic of EGE and is driven by several T-helper type 2 (Th2)-dependent cytokines and induced by food allergy. Due to the lack of a diagnostic gold standard, EGE has a high rate of delayed diagnosis or misdiagnosis. However, several new diagnostic strategies have been developed, such as novel genetic biomarkers and imaging tests. Although dietary therapy and corticosteroids remain the common choices for EGE treatment, recent decades have seen the emergence of novel treatment alternatives, such as biologics that target particular molecules involved in the pathogenic process. Preliminary investigations and clinical trials have demonstrated the efficacy of biologics and provided additional insights for the era of refractory or corticosteroid-dependent EGE biologics.

Objective To explore the optimal parameters for virtual mono-energetic imaging of liver solid lesions. Methods A retrospective analysis was performed on 60 patients undergoing contrast-enhanced spectral CT of the abdomen.The iodine concentration values of hepatic arterial phase images and the CT values of different mono-energetic images were measured.The correlation coefficient and coefficient of variation were calculated. Results The average correlation coefficients between iodine concentrations and CT values of hepatic solid lesion images at 40,45,50,55,60,65,and 70 keV were 0.996,0.995,0.993,0.989,0.978,0.970,and 0.961,respectively.The correlation coefficients at 40(P=0.007),45(P=0.022),50 keV (P=0.035)were higher than that at 55 keV,and the correlation coefficients at 40 keV(P=0.134) and 45 keV(P=0.368) had no significant differences from that at 50 keV.The coefficients of variation of the CT values at 40,45,and 50 keV were 0.146,0.154,and 0.163,respectively. Conclusion The energy of 40 keV is optimal for virtual mono-energetic imaging of liver solid lesions in the late arterial phase,which is helpful for the diagnosis of liver diseases.

Analysis of risk factors of mortality in infants and toddlers with moderate to severe pediatric acute respiratory distress syndrome / 中华儿科杂志

Objective: To identify the risk factors in mortality of pediatric acute respiratory distress syndrome (PARDS) in pediatric intensive care unit (PICU). Methods: Second analysis of the data collected in the "efficacy of pulmonary surfactant (PS) in the treatment of children with moderate to severe PARDS" program. Retrospective case summary of the risk factors of mortality of children with moderate to severe PARDS who admitted in 14 participating tertiary PICU between December 2016 to December 2021. Differences in general condition, underlying diseases, oxygenation index, and mechanical ventilation were compared after the group was divided by survival at PICU discharge. When comparing between groups, the Mann-Whitney U test was used for measurement data, and the chi-square test was used for counting data. Receiver Operating Characteristic (ROC) curves were used to assess the accuracy of oxygen index (OI) in predicting mortality. Multivariate Logistic regression analysis was used to identify the risk factors for mortality. Results: Among 101 children with moderate to severe PARDS, 63 (62.4%) were males, 38 (37.6%) were females, aged (12±8) months. There were 23 cases in the non-survival group and 78 cases in the survival group. The combined rates of underlying diseases (52.2% (12/23) vs. 29.5% (23/78), χ2=4.04, P=0.045) and immune deficiency (30.4% (7/23) vs. 11.5% (9/78), χ2=4.76, P=0.029) in non-survival patients were significantly higher than those in survival patients, while the use of pulmonary surfactant (PS) was significantly lower (8.7% (2/23) vs. 41.0% (32/78), χ2=8.31, P=0.004). No significant differences existed in age, sex, pediatric critical illness score, etiology of PARDS, mechanical ventilation mode and fluid balance within 72 h (all P>0.05). OI on the first day (11.9(8.3, 17.1) vs.15.5(11.7, 23.0)), the second day (10.1(7.6, 16.6) vs.14.8(9.3, 26.2)) and the third day (9.2(6.6, 16.6) vs. 16.7(11.2, 31.4)) after PARDS identified were all higher in non-survival group compared to survival group (Z=-2.70, -2.52, -3.79 respectively, all P<0.05), and the improvement of OI in non-survival group was worse (0.03(-0.32, 0.31) vs. 0.32(-0.02, 0.56), Z=-2.49, P=0.013). ROC curve analysis showed that the OI on the thind day was more appropriate in predicting in-hospital mortality (area under the curve= 0.76, standard error 0.05,95%CI 0.65-0.87,P<0.001). When OI was set at 11.1, the sensitivity was 78.3% (95%CI 58.1%-90.3%), and the specificity was 60.3% (95%CI 49.2%-70.4%). Multivariate Logistic regression analysis showed that after adjusting for age, sex, pediatric critical illness score and fluid load within 72 h, no use of PS (OR=11.26, 95%CI 2.19-57.95, P=0.004), OI value on the third day (OR=7.93, 95%CI 1.51-41.69, P=0.014), and companied with immunodeficiency (OR=4.72, 95%CI 1.17-19.02, P=0.029) were independent risk factors for mortality in children with PARDS. Conclusions: The mortality of patients with moderate to severe PARDS is high, and immunodeficiency, no use of PS and OI on the third day after PARDS identified are the independent risk factors related to mortality. The OI on the third day after PARDS identified could be used to predict mortality.

OBJECTIVE@#To investigate the effect of midazolam on pain in lumbar disc herniation model rats based on p38 MAPK signaling pathway.@*METHODS@#Fifty SPF-grade Sprague-Dawley healthy rats, half male and half female, were selected and randomly divided into normal group, model group, and low-dose, medium-dose, high-dose groups. Model group and low-dose, medium-dose, high-dose groups were initially modeled for lumbar disc herniation. Intraperitoneal injection of saline was performed in rats of normal and model groups; and in the low-dose, medium-dose, and high-dose groups, intraperitoneal injection of midazolam was performed with doses of 30, 60, and 90 mg/kg, respectively. Interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), 5-hydroxytryptamine (5-HT), β-endorphin (β-EP), substance P (SP), neuropeptide Y (NPY) were detected in the serum of rats by enzyme-linked immunoassay. The expression of p38 MAPK and matrix metalloproteinase-3(MMP-3) protein were detected by Western blot in the tissues of rats of each group.@*RESULTS@#The levels of TNF-α, IL-1β and β-EP were higher and the level of 5-HT was lower in the model group than in the normal group(P<0.05);the levels of TNF-α, IL-1β and β-EP were lower and the level of 5-HT was higher in the low-dose, medium-dose and high-dose groups than in the model group(P<0.05). The levels of SP and NPY increased in the model group compared with the normal group (P<0.05) and the levels of SP and NPY decreased in the low-dose, medium-dose and high-dose groups compared with the model group (P<0.05). The expression of p38 MAPK and MMP-3 increased in the model group compared with the normal group (P<0.05); the expression of p38 MAPK and MMP-3 decreased in the low-dose, medium-dose and high-dose compared with the model group(P<0.05).@*CONCLUSION@#Midazolam may ameliorate the immune inflammatory response in rats with a model of lumbar disc herniation, possibly regulated through the p38MAPK signaling pathway.

Value of combined baseline serum HBV markers in predicting HBeAg seroconversion in chronic hepatitis B patients treated by nucleos(t)ide analogues / 临床肝胆病杂志

Objective To investigate the ability of combined baseline serum markers, i.e., HBV DNA, HBV RNA, HBsAg, and HBcrAg, to predict HBeAg seroconversion in patients with HBeAg-positive chronic hepatitis B (CHB) treated by nucleos(t)ide analogues. Methods A retrospective analysis was performed for 83 HBeAg-positive patients selected as subjects from the prospective CHB follow-up cohort established by Difficult & Complicated Liver Diseases and Artificial Liver Center, Beijing YouAn Hospital, Capital Medical University, from June 2007 to July 2008, and the baseline serum levels of HBV DNA, HBV RNA, HBsAg, and HBcrAg were analyzed. The t -test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The Spearman method was used for correlation analysis. A Cox regression model was established to calculate HBeAg seroconversion prediction score, and the time-dependent receiver operating characteristic curve was used to evaluate the ability of combined markers in predicting HBeAg seroconversion. The Kaplan-Meier method was used to calculate cumulative seroconversion rate in each group, and the Log-rank test was used for comparison between groups. Results For the 83 HBeAg-positive patients, the median follow-up time was 108 months, and 44.58%(37/83) of these patients achieved HBeAg seroconversion. Compared with the non-seroconversion group, the HBeAg seroconversion group had significantly lower baseline serum levels of HBV DNA [6.23(1.99-9.28) log 10 IU/mL vs 7.69(2.05-8.96) log 10 IU/mL, Z =-2.345, P =0.019] and HBV RNA [4.81(1.40-7.53) log 10 copies/mL vs 6.22(2.00-8.49) log 10 copies/mL, Z =-1.702, P =0.010], and there were no significant differences in the levels of HBsAg and HBcrAg between the two groups ( P > 0.05). The Cox regression equation constructed based on the above serum markers showed a median score of 0.95(range 0.37-3.45) for predicting HBeAg seroconversion. In the total population, the combined score was negatively correlated with HBsAg, HBV DNA, HBV RNA, and HBcrAg ( r =-0.697, -0.787, -0.990, and -0.819, all P < 0.001). Based on the median prediction score, the patients were divided into high HBeAg seroconversion group and low HBeAg seroconversion group; as for the prediction of HBeAg seroconversion rate at 36, 60, and 84 months, the high HBeAg seroconversion group had a seroconversion rate of 43.90%, 51.20%, and 63.10%, respectively, while the low HBeAg seroconversion group had a seroconversion rate of 9.60%, 17.00%, and 19.8%, respectively, and there was a significant difference between the two groups ( χ 2 =11.6, P < 0.001). Conclusion The combined prediction score based on baseline serum HBV markers can predict HBeAg seroconversion in CHB patients treated by nucleos(t)ide analogues.

Research progress on the relation and related mechanism of night shift work and cardiovascular disease / 中华劳动卫生职业病杂志

Cardiovascular disease is a class of diseases involving the heart or blood vessels, which accounts for about one-third of all deaths worldwide each year. Unhealthy diet, lack of physical activity, smoking and excessive alcohol consumption are all risk factors for cardiovascular disease. With the increasing number of night shift workers, the number of patients with cardiovascular disease has increased, and night shift work has gradually become a risk factor of cardiovascular disease. At present, the mechanism of cardiovascular disease caused by night shift work is still unclear. This review summarizes the relationship between night shift work and cardiovascular disease and its related biochemical indicators, and discusses the research on related mechanisms.

Efficacy of nutrition intervention combined with rehabilitation exercise in elderly patients with chronic heart failure complicated by sarcopenia / 中华健康管理学杂志

Objective:To analyze the efficacy of nutrition intervention combined with rehabilitation exercise in elderly patients with chronic heart failure (CHF) complicated by sarcopenia.Methods:In this randomized controlled trial, seventy CHF patients with sarcopenia, aged 80 years or older, who had received standard CHF medication treatment and had stable conditions with preserved ejection fraction (HFpEF) from June 2021 to October 2022 at the China-Japan Friendship Hospital outpatient clinic were continuously selected. The patients were randomly divided into a test group ( n=35) and a control group ( n=35) using a random number table. The test group continued the original heart failure medication treatment, and on the basis of daily meal, supplemented with whey protein powder [37 g per serving (including 16.2 g of whey protein, 145 kcal), twice a day]; they were given resistance exercise primarily focused on resistance training (5 sets of exercises, progressively increasing to 3 days per week, twice a day, 5 sets per session, 20 repetitions per set). The control group maintained the original heart failure medication treatment plan and lifestyle. The body mass index, appendicular skeletal muscle mass index (ASMI), grip strength, Five-Times-Sit-to-Stand Test, 6-meter walking speed, 6-minute walk test, brain natriuretic peptide (BNP), left ventricular ejection fraction, ratio of early mitral flow peak velocity to early mitral annulus diastolic peak velocity (E/e′), serum albumin, hemoglobin, and serum creatinine were compared between the two groups before and after 3 months of intervention using t-tests and chi-square tests to analyze the efficacy of nutrition intervention combined with rehabilitation exercise in elderly patients with CHF complicated by sarcopenia. Results:Among the 70 patients, there were 42 males and 28 females. There was no significant difference in baseline data between the test group and the control group (all P>0.05). After 3 months of intervention, ASMI, grip strength and 6 min walking distance in the test group were all significantly higher than those in the control group [(6.43±1.07) vs (6.09±0.86) kg/m 2, (27.75±2.13) vs (23.45±0.47) kg, (361.51±58.71) vs (273.50±69.85) m], and significantly higher than those before intervention [(5.99±1.45) kg/m 2, (23.55±9.64) kg, (273.50±69.86) m]. The time of Five-Times-Sit-to-Stand Test, BNP and E/e′ in the test group were both significantly lower than those in the control group [(11.20±2.09) vs (15.36±0.46) s, (278.80±58.69) vs (400.80±87.86) ng/L, (11.10±0.81) vs (14.66±1.90)], and significantly lower than those before intervention [(18.51±2.90) s, (407.50±122.74) ng/L and (14.00±1.15)]. There was no significant difference in remaining indicators between the two groups (all P>0.05). Conclusion:Nutritional intervention combined with rehabilitation exercise primarily focused on whey protein supplementation and resistance training can significantly improve limb muscle mass, muscle strength, muscle function, and cardiac function in elderly patients with CHF complicated by sarcopenia on the basis of heart failure medication treatment.
