Objective To explore the therapeutic effect of Huoxue Tongluo Decoction combined with empagliflozin on patients with heart failure with reduced ejection fraction (HFrEF), and analyze its influence on traditional Chinese medicine syndrome scores and cardiac function. Methods A retrospective analysis was performed on 150 HFrEF patients treated in our hospital from August 2024 to August 2025. The patients were divided into control group and observation group according to different treatment regimens, 75 patients receiving empagliflozin alone constituted the control group, while another 75 cases treated with combined Huoxue Tongluo Decoction and empagliflozin were assigned to the observation group. The clinical efficacy, as well as the traditional Chinese medicine syndrome scores, Lee heart failure score, cardiac function 6-minute walk test (6MWT), heart failure factors [cardiac troponin I (cTnI), soluble suppression of tumorigenicity 2 (sST2) and N-terminal pro-B-type natriuretic peptide (NT-proBNP)], hemodynamic parameters, inflammatory factors [interleukin-6 (IL-6), C-reactive protein (CRP), interleukin-1β (IL-1β) and pentraxin-3 (PTX-3)], oxidative stress indexes [glutathione peroxidase-3 (GPX-3), malondialdehyde (MDA), superoxide dismutase (SOD), lipid peroxide (LPO) and total antioxidant capacity] before and after treatment were compared between the two groups. Adverse reactions and readmission rate were also compared. Results The total effective rate of observation group was higher than that of control group (P<0.05). After treatment, traditional Chinese medicine syndrome scores and Lee heart failure score in observation group were lower (P<0.05). LVEDD, LVESD, LVEDV, LVESD and serum levels of cTnI, sST2, NT-proBNP decreased, while LVEF and 6MWT increased in observation group (P<0.05). The improvement of hemodynamics in observation group was superior to control group after treatment (P<0.05). After treatment, serum levels of IL-6, CRP, IL-1β, PTX-3, MDA and LPO were decreased, while GPX-3, SOD and total antioxidant capacity were increased in observation group compared with control group (P<0.05). The readmission rate was lower in observation group (P<0.05). No significant difference was found in adverse reactions between the two groups (P>0.05). Conclusion Huoxue Tongluo Decoction combined with empagliflozin can elevate therapeutic efficacy, relieve clinical symptoms, improve cardiac function and hemodynamic status, reduce inflammatory and oxidative stress responses, and cut down readmission incidence with favorable safety in HFrEF patients.

Objective : To investigate the effect of lidocaine combined with esketamine on recovery quality and cognitive function in patients undergoing lung surgery. Methods : A total of 100 patients receiving pulmonary resection at our hospital between July 2023 and December 2025 were enrolled and randomized via a random number table into two equal arms (n=50 per group): observation and control. The control group was treated with routine anesthesia to maintain anesthesia, and the observation group was treated with lidocaine and esketamine on the basis of routine anesthesia. The recovery quality [ Riker sedation agitation score ( SAS ) at 30 min after extubation, recovery time, extubation time ], cognitive function [ simple mental state examination score ( MMSE ) before operation and 1 d, 3 d after operation ], perioperative hemodynamic indexes [ mean arterial pressure ( MAP ), heart rate ( HR ) before anesthesia drug infusion ( T0 ), tracheal intubation ( T1 ), 5 min after extubation ( T2 ) ] and the incidence of adverse reactions at 72 h after operation were compared between the two groups. Results : In the observation group, the SAS score measured 30 minutes post-extubation and the MMSE scores at 1 day and 3 days post-operation were significantly higher than those in the control group. Conversely, both recovery and extubation times were shorter in the observation group compared to the control group. No significant differences in MAP and HR were observed at T0, T1, and T2 within the observation group (P > 0.05). In contrast, within the control group, MAP and HR at T1 and T2 were notably elevated compared to T0, with the differences being statistically significant (P < 0.05). Conclusion : The application of lidocaine combined with esketamine in lung surgery can improve the quality of recovery, protect postoperative cognitive function, maintain perioperative hemodynamic stability, and has good safety.

To evaluate the effectiveness of an intervention combining Root Cause Analysis (RCA)–based quality management and Psychological Capital (PsyCap) theory in reducing communication interruptions and improving communication quality and teamwork in surgical safety check teams. Methods: Eighty surgical team members from a tertiary hospital (January 2025 - December 2025.) were assigned to a control group or an intervention group according to operating room allocation (40 per group). The control group followed routine surgical safety check procedures, whereas the intervention group additionally received an RCA-guided workflow analysis and a PsyCap-based communication enhancement program. Post-intervention outcomes included communication interruption rate, execution quality and efficiency of safety checks, Psychological Capital Questionnaire (PCQ-24) scores, and TeamSTEPPS Teamwork Perceptions Questionnaire (T-TPQ) scores. Results: The intervention group demonstrated a significantly lower communication interruption rate compared with the control group (P＜0.05). Execution quality and communication efficiency were significantly improved in the intervention group (P＜0.001). PCQ-24 total and subscale scores were significantly higher in the intervention group than in the control group (P＜0.001), as were T-TPQ total and subscale scores (P＜0.001). Conclusion: Integrating RCA-based workflow optimization with PsyCap-oriented psychological and behavioral training can effectively enhance communication quality, reduce interruptions, and strengthen teamwork in surgical safety check teams. The combined model has strong applicability and potential for wider clinical promotion.
