OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is a major chronic respiratory condition with high morbidity and mortality, imposing a serious economic and public health burden. The World Health Organization ranks COPD among the top 4 chronic diseases worldwide. Zangsiwei Qingfei Mixture (ZSWQF), a novel Tibetan herbal formulation independently developed by our research team, has shown therapeutic potential for chronic respiratory diseases. This study aims to evaluate the effects of aerosolized ZSWQF on cigarette smoke-induced COPD in mice and explore its underlying mechanisms. METHODS: Thirty C57 mice were randomly divided into a Control group, a COPD group, and a ZSWQF group. The Control group received saline aerosol inhalation without cigarette smoke exposure; both the COPD group and the ZSWQF group were exposed to cigarette smoke, with the former receiving saline inhalation and the latter treated with ZSWQF aerosol. White blood cell (WBC) count was performed using a fully automatic blood cell analyzer. Serum, alanine transaminase (ALT), and serum creatinine (SCr), as well as interleukin (IL)-6, IL-8, and tumor necrosis factor (TNF)-α levels in serum and bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay (ELISA). BALF cell classification was determined using a hematology analyzer. Lung function was assessed with a small animal pulmonary function system, including airway resistance (RI) and cyclic dynamic compliance (CyDN). Lung tissues were stained with hematoxylin and eosin (HE), and mean linear intercept (MLI) and destruction index (DI) were calculated to evaluate morphological changes. Network pharmacology was applied to identify disease-related and ZSWQF-related targets, followed by intersection and protein-protein interaction (PPI) network analysis, and enrichment analysis of biological functions and pathways. Primary type II alveolar epithelial cell (AEC II) from SD rats were isolated and divided into a Control group, a lipopolysaccharide (LPS) group, a normal serum group, a water extract of ZSWQF (W-ZSWQF) group, a ZSWQF containing serum group, and a MLN-4760 [angiotensin-converting enzyme (ACE) 2 inhibitor]. Western blotting was performed to assess protein expression of ACE, p38 [a mitogen-activated protein kinase (MAPK)], phospho (p)-p38, extracellular signal-regulated kinases 1 and 2 (ERK1/2), p-ERK1/2, c-Jun N-terminal kinase (JNK), p-JNK, inhibitor of nuclear factor-kappa B alpha (IκBα), p-IκBα, and p-p65 subunit of nuclear factor-kappa B (NF-κBp65). RESULTS: WBC counts were significantly higher in the COPD group than in controls (P<0.01) and decreased following ZSWQF treatment (P<0.05). No significant intergroup differences were found in organ weights, ALT, or SCr (all P>0.05). Serum and BALF levels of IL-6, IL-8, and TNF-α, as well as total BALF cells, neutrophils, and macrophages, were elevated in the COPD group compared with controls and reduced by ZSWQF treatment (P<0.05). COPD mice exhibited increased RI, decreased CyDN, marked alveolar congestion, inflammatory infiltration, thickened septa, and higher MLI and DI values versus controls (P<0.05); ZSWQF treatment significantly reduced MLI and DI (P<0.05). Network pharmacology identified 151 potential therapeutic targets for ZSWQF against COPD, with key nodes including TNF, IL-6, protein kinase B (Akt) 1, albumin (ALB), tumor protein p53 (TP53), non-receptor tyrosine kinase (SRC), epidermal growth factor receptor (EGFR), signal transducer and activator of transcription 3 (STAT) 3, matrix metalloproteinase (MMP)-9, and beta-catenin (CTNNB1). Enrichment analysis indicates involvement of cancer-related, phosphatidylinositol 3-kinase (PI3K)/Akt, hypoxia-inducible factor (HIF)-1, calcium, and MAPK signaling pathways. Western blotting results showed that compared with the LPS group, AEC II treated with ZSWQF-containing serum exhibited decreased expression of ACE, p-p38/p38, p-ERK1/2/ERK1/2, p-JNK/JNK, p-IκBα/IκBα, and p-NF-κBp65, while ACE2 expression was upregulated, consistent with the MAPK/nuclear factor-kappa B (NF-κB) pathway regulation predicted by network pharmacology. CONCLUSIONS Aerosolized ZSWQF provides protective effects in COPD mice by reducing airway inflammation and remodeling.

Objective:To develop the Postoperative Subdelirium Syndrome Knowledge, Attitude, and Practice Questionnaire for Surgical Nurses and test its reliability and validity.Methods:Based on the theory of knowledge, attitude, and practice, the preliminary Postoperative Subdelirium Syndrome Knowledge, Attitude, and Practice Questionnaire for Surgical Nurses was developed through literature search and analysis, Delphi expert consultation, and pre-survey. From February to April 2022, convenience sampling was used to select 375 surgical nurses from five Class Ⅲ Grade A hospitals and three Class Ⅲ Grade B hospitals in Zhejiang Province for questionnaire item analysis, exploratory factor analysis, and reliability testing.Results:The final Postoperative Subdelirium Syndrome Knowledge, Attitude, and Practice Questionnaire for Surgical Nurses consisted of 33 items in three dimensions of knowledge, attitude, and practice. Exploratory factor analysis extracted three common factors with a cumulative variance contribution rate of 67.016%. The total Cronbach's α coefficient of the questionnaire was 0.931, and the Cronbach's α coefficients for each dimension were 0.972, 0.906, and 0.932, respectively. The overall test-retest reliability coefficient of the questionnaire was 0.999, and the test-retest reliability coefficients for each dimension were 0.997, 0.994, and 0.998. The questionnaire-level content validity index was 0.889, and the item-level content validity index was 0.833 to 1.000.Conclusions:The Postoperative Subdelirium Syndrome Knowledge, Attitude, and Practice Questionnaire for Surgical Nurses has good reliability and validity, and can be used to evaluate the knowledge, attitude, and practice of postoperative subdelirium syndrome among surgical nurses.

Objective:Chronic obstructive pulmonary disease(COPD)is a significant global public health issue.Modern medical treatments have both benefits and limitations,prompting increasing attention from scholars worldwide on traditional ethnic medicine,and the Zangsiwei Qingfei Mixture is a newly developed formula derived from the effective components of classical Tibetan medicine to treat chronic respiratory diseases.This study aims to investigate the clinical efficacy and safety of the Zangsiwei Qingfei Mixture combined with conventional treatment in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD). Methods:Sixty AECOPD patients admitted to the Second Xiangya Hospital of Central South University from May 2021 to May 2023 were enrolled and randomly divided into 2 groups,with 30 patients in each group.The control group received conventional treatment,including bronchodilators,anti-infection agents,expectorants,and oxygen therapy.The experimental group received the Zangsiwei Qingfei Mixture in addition to conventional treatment.The treatment duration was 7 d for both groups.Baseline data such as gender,age,body mass index(BMI),smoking status,Global Initiative for Chronic Obstructive Lung Disease(GOLD)classification,COPD course,and the number of COPD exacerbations in the past year were collected.The primary efficacy indicators were assessed using the modified Medical Research Council(mMRC)dyspnea scale and the modified Borg scale.Secondary indicators included arterial lactic acid(LAC)and serum tumor necrosis factor alpha(TNF-α)levels.Safety indicators included liver and kidney function[alanine transaminase(ALT),aspartate transaminase(AST),serum creatinine(SCr),serum uric acid(SUA)],coagulation function[activated partial thromboplastin time(APTT),prothrombin time(PT),fibrinogen(FIB),and D-dimer].The generalized linear mixed model(GLMM)was used to evaluate the clinical efficacy and safety of the Zangsiwei Qingfei Mixture. Results:Before treatment,there were no statistically significant differences in general baseline data,grading of mMRC dyspnea scale,score of modified Borg scale,arterial LAC,ALT,AST,SCr,SUA,APTT,FIB,and D-dimer between the 2 groups(all P＞0.05).However,serum TNF-α and PT levels in the experimental group were significantly lower than those in the control group(both P＜0.05).GLMM analysis showed that after adjusting for pre-and post-treatment,gender,age,BMI,smoking status,GOLD classification,COPD course,and the number of COPD exacerbations in the past year,the experimental group demonstrated significantly lower grading of mMRC dyspnea scale(coefficient=-0.329,P=0.036),score of modified Borg scale(coefficient=-1.077,P=0.001),serum TNF-α level(coefficient=-14.378,P＜0.001),and arterial LAC level(coefficient=-0.409,P=0.012)compared to the control group.The Zangsiwei Qingfei Mixture had no significant effect on liver,kidney,or coagulation function indicators(all P＞0.05). Conclusion:The Zangsiwei Qingfei Mixture combined with conventional treatment can improve clinical symptoms and promote homeostasis in AECOPD patients,demonstrating safety and reliability.Combining modem medicine with traditional ethnic medicine offers a feasible approach to treating chronic respiratory diseases in the future.

Objective:To investigate the effect of Edaravone and dexborneol(Eda.B)on oxidative stress pathway in peripheral blood of elderly patients with acute ischemic stroke.Methods:A total of 87 elderly patients with acute ischemic stroke in the Department of Neurology, Qinghai University Affiliated Hospital from July 2021 to January 2022 were selected as the study subjects.According to the random number table, they were divided into control group(44 cases)and edaravone dexborneol group(43 cases). Each group was divided into <12 h group, 12-24 h group and 24-48 h group according to the time of onset.Peripheral blood was collected in each group at admission and discharge, respectively.The serum levels of reactive oxygen species(ROS), Kelch-like epichlorohydrin-associated protein 1(Keap1), nuclear factor-E2-associated factor 2(Nrf2), heme oxygenase-1(HO-1), NAD(P)H quinone oxidoreductase 1(NQO1), tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6), as well as superoxide dismutase(SOD)activity and malondialdehyde(MDA)content were detected.Results:Elderly patients with acute ischemic stroke receving Eda.B treatment after admission could reduce the serum concentration of ROS, TNF-α and IL-6, as well as MDA content, and increase the concentration of Keap1, Nrf2, HO-1 and NQO1 and SOD activity.Except for ROS concentration in <12 h group and SOD activity in <12 h and 12 h-24 h groups, the differences between the other groups were statistically significant( P<0.05 for all). Compared with the control group, the serum concentration of TNF-α and IL-6 of patients in the Eda.B group at discharge decreased, while the concentration of Nrf2(24-48 h group)and HO-1(24-48 h group), and SOD activity increased, the differences were statistically significant( P<0.05 for all). In the control group at discharge, the concentrations of ROS(24-48 h group), TNF-α(<12 h group, 24-48 h group)and IL-6, as well as MDA content decreased, while the concentrations of Keap1, Nrf2(<12 h group, 12-24 h group)and HO-1(<12 h group, 12-24 h group)increased, the differences were also statistically significant( P<0.05 for all). Compared with admission, the concentration of Keap1(24-48 h group)and HO-1(24-48 h group), the activity of SOD(<12 h group, 12-24 h group)increased and the content of MDA(12-24 h group)in the Eda.B group decreased at discharge( P<0.05 for all). Conclusions:Eda.B can reduce oxidative stress and inflammatory response in peripheral blood of elderly patients with acute ischemic stroke by acting on the Keap1/Nrf2 pathway.

Objective:To explore the expression of fructose bisphosphate aldolase A (ALDOA) in the bone marrow of patients with acute myeloid leukemia (AML) and the correlation with clinical features and prognosis.Methods:The bone marrow samples of 90 newly diagnosed AML (non-acute promyelocytic leukemia) patients and 18 allogeneic hematopoietic stem cell transplantation donors who were treated from January 2013 to December 2015 in the First Affiliated Hospital of Zhengzhou University and the Children's Hospital Affiliated to Zhengzhou University were collected. The relative expression level of ALDOA mRNA in bone marrow samples was detected by using real-time quantitative polymerase chain reaction (qRT-PCR). Clinical data of these patients were retrospectively analyzed, and the patients were divided into continuous complete remission (CR) group and refractory recurrent (RR) group according to the clinical response and follow-up results. The differences of the relative expression level of ALDOA mRNA between AML group and the normal control group, CR group and RR group were analyzed. Univariate and multivariate Cox regression risk model were used for analysis of factors influencing prognosis of AML patients.Results:The relative expression level of ALDOA mRNA in AML group was higher than that in normal control group [(5.71±0.44) vs. (1.10±0.08), t = 4.74, P<0.001]. The relative expression level of ALDOA mRNA in the RR group was higher than that in the CR group [(6.69±0.67) vs. (4.30±0.36) , t = 2.79, P < 0.001]. In addition, there were statistically significant differences in the proportion of patients with ALDOA mRNA high expression and those with ALDOA mRNA low expression stratified by the number of white blood cell, the proportion of bone marrow blasts and whether complete remission could be achieved or not after 1 course of induction therapy (all P < 0.05). Overall survival in patients with ALDOA high expression was worse than that in patients with ALDOA low expression ( χ2 = 5.59, P = 0.018). Multivariate analysis showed that white blood cell count, prognosis stratification, whether complete remission could be achieved or not after 1 course of induction therapy and ALDOA expression were the independent prognostic factors for the death of AML patients (all P < 0.05). Conclusions:ALDOA may play an important role in the development and progression of AML, and the expression level of ALDOA in the bone marrow can be used as an index for the prognosis assessment of AML patients and may be a potential therapeutic target for AML.

Objective: To explore the association of 21 gene recurrence score(RS)according to TAILORx standard and prognosis of hormone receptor(HR) positive, axillary lymph node negative breast cancer. Methods: The clinicopathologic data of 558 early breast cancer patients who underwent 21 gene RS testing from May 2012 to Jan 2017 were retrospectively analyzed. RS was subgrouped according to TAILORx standard.Estimates of relapse free survival(RFS) were made from the Kaplan-Meier curves. Results: In 558 patients, RS≤10, RS 11-25 and RS≥26 groups accounted for 23.1%, 63.6% and 13.3%.After a median follow-up of 38 months, the recurrence ratesin RS≤10, RS 11-25 and RS≥26 groups were 3.3%, 4.5% and 5.4%, respectively. Kaplan-Meier RFS curve showed no significant difference between the 3 groups(P=0.788). The recurrence ratesin RS≤15 group(3.0%) was significantly lower than that in RS≥16 group(5.9%)(P=0.041). Conclusions A significant association exists between RS and breast cancer prognosis.It is rational not to give chemotherapy to RS<18 low risk patients according to classical standard.
