ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
“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.
ABSTRACT
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.

ABSTRACT
Objective To analyze the results of remote screening for diabetic retinopathy (DR) in a community, and to provide a basis for early intervention of DR in the community. Methods A cross-sectional research method was used to conduct eye health screening on 1299 diabetic patients in Jiangqiao Town, Shanghai from January 2018 to December 2019. Using remote screening technology and information transmission methods, DR diagnosis was carried out by Shanghai Eye Prevention Institute. Chi-square test, rank sum test and other methods were used to statistically analyze the prevalence and influencing factors of DR. Results The detection rate of DR patients in the jurisdiction was 19.32%. The differences between different age groups and different DR groups were statistically significant. The older the age, the higher the prevalence of moderate and severe DR (χ2=79.42, P<0.00). The proportion of DR patients with visual acuity <0.3 was 22.98%, which was significantly higher than that of non-DR patients (17.40%). Conclusion The DR prevalence rate of diabetic population in Jiangqiao Town is at a medium level, and the severity of DR is mostly moderate. The screening model of diabetic eye disease based on the cooperation between community health centers and professional eye care centers is of great significance to the prevention and treatment of DR.
ABSTRACT
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.

ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
Pollen food allergy syndrome (PFAS) is an IgE-mediated allergic reaction that occurs when some pollinosis patients ingest certain plant-derived food that contains cross-reactive allergenic components. PFAS is prevalent in both children and adult pollinosis patients. In most cases, PFAS symptoms are confined to the oropharynx and occur within several minutes after oral contact with food. Therefore, PFAS has been also referred as oral allergy syndrome (OAS). A small proportion of PFAS patients would experience systemic symptoms or anaphylaxis. Currently, the diagnosis of PFAS is mainly based on clinical history and allergic tests [skin prick tests and(or) serum specific IgE tests]. Oral provocation tests are used to verify atypical patients. Component-resolved diagnosis is essential for further precise diagnosis and treatment. Management options for PFAS include lifestyle adjustment, symptomatic medication, and immunotherapy. The efficacy and appropriate population for immunotherapy need further investigation. This article aims to update the knowledge on epidemiology, pathogenesis and clinical management of PFAS, thereby enhancing clinicians' understanding as well as treatment progress of this disease entity.

This study investigated the effect of Xiaoxuming Decoction(XXMD) on the activation of astrocytes after cerebral ischemia/reperfusion(I/R) injury. The model of cerebral IR injury was established using the middle cerebral artery occlusion method. Fluorocitrate(FC), an inhibitor of astrocyte activation, was applied to inhibit astrocyte activation. Rats were randomly divided into a sham group, a model group, a XXMD group, a XXMD+FC group, and a XXMD+Vehicle group. Neurobehavioral changes at 24 hours after cerebral IR injury, cerebral infarction, histopathological changes observed through HE staining, submicroscopic structure of astrocytes observed through transmission electron microscopy, fluorescence intensity of glial fibrillary acidic protein(GFAP) and thrombospondin 1(TSP1) measured through immunofluorescence, and expression of GFAP and TSP1 in brain tissue measured through Western blot were evaluated in rats from each group. The experimental results showed that neurobehavioral scores and cerebral infarct area significantly increased in the model group. The XXMD group, the XXMD+FC group, and the XXMD+Vehicle group all alleviated neurobehavioral changes in rats. The pathological changes in the brain were evident in the model group, while the XXMD group, the XXMD+FC group, and the XXMD+Vehicle group exhibited milder cerebral IR injury in rats. The submicroscopic structure of astrocytes in the model group showed significant swelling, whereas the XXMD group, the XXMD+FC group, and XXMD+Vehicle group protected the submicroscopic structure of astrocytes. The fluorescence intensity and protein expression of GFAP and TSP1 increased in the model group compared with those in the sham group. However, the XXMD group, the XXMD+FC group, and XXMD+Vehicle group all down-regulated the expression of GFAP and TSP1. The combination of XXMD and FC showed a more pronounced effect. These results indicate that XXMD can improve cerebral IR injury, possibly by inhibiting astrocyte activation and down-regulating the expression of GFAP and TSP1.

Mesenchymal stem cells (MSCs) have been officially approved in many countries to treat graft-versus-host disease, autoimmune disorders and those associated with tissue regeneration after hematopoietic stem cell transplantation. Studies in recent years have confirmed that MSC acts mainly through paracrine mechanism, in which extracellular vesicles secreted by MSC (MSC-EV) play a central role. MSC-EV has overwhelming advantages over MSC itself in the setting of adverse effects in clinical application, indicating that MSC-EV might take the place of its parent cells to be a potentially therapeutic tool for "cell-free therapy". The pharmaceutical properties of MSC-EV largely depend upon the practical and optimal techniques including large-scale expansion of MSC, the modification of MSC based on the indications and the in vivo dynamic features of MSC-EV, and the methods for preparing and harvesting large amounts of MSC-EV. The recent progresses on the issues above will be briefly reviewed.

Objective:To explore the pathogenesis of gallbladder cholesteryl polyps (GCP) and gallbladder cholesterol calculus (GCC) by studying the different changes of mucin (MUC) expression and reverse cholesterol transporter (RCT) in gallbladder mucosa epithelium.Methods:The data of 10 GCP patients (GCP group), 10 GCC patients (GCC group) and 5 patients with normal gallbladder resection (control group) were retrospectively analyzed, who underwent cholecystectomy in the Department of General Surgery, Xuanwu Hospital, Capital Medical University from January to December 2021. Among the 10 patients in the GCP group, there were 5 males and 5 females, aged (43.40±9.59) years old. Among the 10 patients in the GCC group, 5 males and 5 female, aged (45.00±8.13) years old. Among the 5 patients in the control group, there were 3 males and 2 females, aged (43.80±6.01) years old. Immunohistochemical analysis was used to investigate the expression differences of various subtypes of MUC and RCT [ATP binding cassette transporter G1 (ABCG1) and B group type I scavenger receptor (SR-BI)] among each group.Results:Compared with the control group, the expression of MUC1 (3.40±0.70 vs. 0), MUC5AC (1.50±0.53 vs. 0), MUC6 (4.70±0.48 vs. 0), and ABCG1 (3.50±0.53 vs. 1.60±0.55) in the gallbladder mucosa of the GCP group increased, while the expression score of SR-BI decreased (1.70±0.48 vs. 3.40±0.55), with statistical significance (all P<0.001). Compared with the control group, the expression of MUC1 (4.80±0.42 vs. 0), MUC5AC (4.70±0.48 vs. 0), MUC6 (3.30±0.67 vs. 0), and ABCG1 (3.40±0.52 vs. 1.60±0.55) in the gallbladder mucosa of the GCC group increased, while the expression score of SR-BI decreased (0 vs. 3.40±0.55), with statistically significant differences (all P<0.001). Conclusion:The different expression levels of MUC1, MUC5AC, MUC6, and RCT proteins lead to the differential formation of GCP and GCC on the basis of the co-pathogenesis in high cholesterol in bile.
ABSTRACT
Objective:To analyze the clinical characteristics of elderly acute pulmonary thromboembolism(APE)patients complicated with preexisting atrial fibrillation(AF)and the impact of preexisting AF on in-hospital adverse outcomes in elderly patients with APE.Methods:A retrospective analysis was performed on elderly APE patients with preexisting AF hospitalized in Beijing Anzhen Hospital, Capital Medical University between January 1, 2008 and December 31, 2021.We compared the comorbidities, symptoms, signs, laboratory test results and echocardiographic features, simplified pulmonary embolism severity index(sPESI)scores and adverse in-hospital outcomes between the preexisting AF group and the non-AF group.Logistic regression was used to analyze the risk factors of in-hospital adverse outcomes in elderly patients with APE.Results:A total of 240 patients diagnosed with APE were enrolled.There were 120 patients in the AF group and 120 patients in the non-AF group.For patients in the AF group and the non-AF group, the proportions with chronic heart failure were 38.3%(46/120)and 15.8%(19/120), the proportions with lower extremity deep vein thrombosis(DVT)were 36.7%(44/120)and 65.8%(79/120), the left ventricular ejection fractions(LVEF)were(59±10)% and(62±7)%, and hospital stays were(15±7)and(11±4)days, respectively, and the differences were statistically significant( χ2=15.381, 20.429, t=2.527, -4.710, all P<0.05). The incidences of in-hospital adverse outcomes in the AF group and the non-AF group were 4.2%(5/120)and 3.3%(4/120), respectively, with no significant difference( χ2=0.000, P=1.000). The overall incidence of in-hospital adverse outcomes was 3.8%(9/240). Multivariate Logistic regression analysis showed that elevated lactic acid was an independent risk factor for in-hospital adverse outcomes( OR=2.753, 95% CI: 1.367-5.542, P=0.005). However, AF( OR=2.880, 95% CI: 0.587-14.141, P=0.192)and sPESI score( OR=2.056, 95% CI: 0.904-4.673, P=0.086)were not associated with in-hospital adverse outcomes. Conclusions:Elderly APE patients with preexisting AF have a relatively low incidence of DVT, but a higher proportion have concurrent chronic heart failure and need a longer hospital stay.Elevated lactic acid is an independent risk factor for in-hospital adverse outcomes of elderly APE patients with preexisting AF.However, preexisting AF has no predictive value for in-hospital adverse outcomes in elderly patients with APE.
ABSTRACT
Objective:To investigate the application of the 7E teaching model (i.e., Elicit, Engage, Explore, Explain, Elaborate, Evaluate, and Extend) combined with standardized patients (SP) in nursing practice teaching for general surgery.Methods:A total of 80 nursing students who were assigned to Department of General Surgery in our hospital were selected and divided into control group and observation group according to the order of admission, with 40 students in each group. The students in the control group received traditional teaching, while those in the observation group received the 7E teaching model combined with SP. Theoretical and practical operation scores were assessed for both groups, and the scores of non-technical skills were compared between the two groups. SPSS 22.0 was used to perform the t-test. Results:Compared with the control group, the observation group had significantly better scores of theoretical assessment (89.36±2.13 vs. 87.64±2.07, P<0.05) and practical operation (92.07±4.33 vs. 85.19±3.46, P<0.05). The observation group had significantly higher scores of non-technical skills (humanistic care ability, ability to stimulate learning interest, communication ability with patients, depth of the understanding of diseases and nursing ability, knowledge extension ability, team collaboration ability, clinical thinking ability, and clinical decision-making ability) than the control group ( P<0.05). Conclusion:The 7E teaching model combined with SP in nursing practice teaching for general surgery can better enhance the theoretical and practical abilities of nursing interns and help to improve the level of non-technical skills.

Objective To improve the quality standard of Xiaojin capsules.Methods The agents content of acetyl-11-keto-β-bos wellic acid in Vinegar frankincense was determined by HPLC.According to GC detection patterns of 15 batches of samples,the similarity evaluation was conducted by using the"similarity evaluation system for chromatographic fingerprint of TCM(2012 edition)"of National Pharmacopoeia Committee to confirm common peaks.According to the Chinese Pharmacopoeia method,the contents of Pb,Cd,Cu,As and Hg in samples were detected.Results The linear range of acetyl-11-keto-β-boswellic acid was 13.346-166.824 μg·ml-1(r=0.999 8).The method which possesses high accuracy,and strong specificity,repeatability is good,and the average recovery was 100.76%with an RSD of 1.52%(n=6).The GC fingerprint detection method of Xiaojin capsules was established,and 11 common peaks were identified.The similarity of 15 batches of samples was greater than 0.870,indicating a good similarity.The contents of Pb,Cd,Cu,As and Hg in 15 batches of samples are in accordance with the reference limits in Chinese Pharmacopoeia.Conclusion The GC fingerprint detection method and the HPLC method for the determination of 11-carbonyl-β-acetylboswellic acid,as well as the examination of heavy metals,it can be used as a quality control item for the enhancement of the quality control standards of Xiaojin capsules.
ABSTRACT
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.
