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.

Abstract Objective: To explore the trajectory of neurological recovery in patients with cerebral hemorrhage and the impact of different trajectories on prognosis based on latent class growth model (LCGM). Methods: The clinical data and neurological function scores [National Institutes of Health Stroke Scale (NIHSS)] of 360 patients with spontaneous cerebral hemorrhage (June 2023 to June 2025) were retrospectively collected, and LCGM was used to identify potential categories of neurological recovery trajectories, analyze risk factors affecting poor recovery trajectories, and compare the prognosis of different trajectories [modified Rankin Scale (mRS), Glasgow Outcome Score (GOS)]. Results: The LCGM model fitting results showed that the three types of trajectories were the optimal fitting model, and 360 patients with spontaneous cerebral hemorrhage could be divided into 139 cases (38.61%) of rapid recovery type, 154 cases (42.78%) of stable recovery type, and 67 cases (18.61%) of poor recovery type; admission to Glasgow Coma Scale (GCS) score, initial NIHSS score, mechanical ventilation, use of vasoactive drugs and hematoma volume are independent influencing factors of poor neurological recovery (P＜0.05); in terms of prognosis, there were significant differences in mRS and GOS scores among the three groups of patients (P＜0.05).Conclusion: Based on LCGM, it is possible to effectively identify the heterogeneous trajectories of neurological function recovery in patients with intracerebral hemorrhage (ICH), while also identifying independent risk factors influencing neurological function repair and establishing associations between different recovery trajectories and prognosis.

目的 分析围绝经期女性糖脂代谢水平与卵巢储备功能减退（DOR）的相关性，并探讨绝经激素治疗的应用价值。方法 回顾性选取2024年2月至2026年2月就诊于本院的194例围绝经期女性为研究对象，根据其卵巢储备功能将其分为DOR组（n=103）与卵巢储备功能正常组（NOR，n=91）。比较2组临床资料，采用Logistic回归分析围绝经期女性DOR的危险因素，绘制ROC曲线分析其预测效能，并利用Spearman相关系数分析指标相关性。同时予以所有患者绝经激素治疗（MHT），比较治疗前后的性激素指标、糖代谢指标、超声指标及安全性指标。结果 Logistic多因素结果显示：年龄、FSH、HbA1c、TG是围绝经期女性DOR的重要影响因素（P＜0.05）。ROC结果显示：联合预测的AUC=0.982，95%CI为0.964~1.000，灵敏度为0.990，特异度为0.923，校准曲线拟合性好。卵巢储备功能与年龄、FSH、HbA1c、TG均呈显著正相关（P均<0.05）。与治疗前相比，FSH、LH、HbA1c、TG、LDL-C水平有明显下降（P＜0.05），子宫内膜厚度略有增加（P＜0.05）；AMH、卵巢体积无显著变化（P＞0.05）。MHT治疗后不良反应发生率为4.64%。结论 糖脂代谢异常与围绝经期女性DOR密切相关，是其重要危险因素。规范MHT干预可有效改善内分泌代谢紊乱，且安全性可靠。

Objective To analyze the correlation between glycolipid metabolism levels and diminished ovarian reserve (DOR) in perimenopausal women, and to explore the application value of menopausal hormone therapy.Methods A total of 194 perimenopausal women admitted to our hospital from February 2024 to February 2026 were retrospectively enrolled. They were divided into the DOR group (n=103) and the normal ovarian reserve (NOR) group (n=91) according to ovarian reserve function. Clinical data were compared between the two groups. Logistic regression analysis was used to identify risk factors for DOR. Receiver operating characteristic (ROC) curves were plotted to evaluate predictive efficacy, and Spearman correlation analysis was performed to assess indicator correlations. All patients received menopausal hormone therapy (MHT). Sex hormone indicators, glycolipid metabolic indicators, ultrasonographic indicators and safety indicators were compared before and after treatment.Results Multivariate Logistic regression showed that age, folliclestimulating hormone (FSH), glycated hemoglobin A1c (HbA1c) and triglyceride (TG) were independent risk factors for DOR in perimenopausal women (P＜0.05). ROC analysis revealed that the combined prediction yielded an AUC of 0.982 (95%CI: 0.964–1.000), with a sensitivity of 0.990 and a specificity of 0.923, and good calibration curve fitting. Ovarian reserve was significantly positively correlated with age, FSH, HbA1c and TG (all P＜0.05). After treatment, levels of FSH, luteinizing hormone (LH), HbA1c, TG and lowdensity lipoproteincholesterol (LDLC) decreased significantly (P＜0.05), and endometrial thickness increased slightly (P＜0.05). No significant changes were observed in antiMüllerian hormone (AMH) and ovarian volume (P＞0.05). The incidence of adverse reactions after MHT was 4.64%.Conclusion Abnormal glycolipid metabolism is closely associated with DOR and serves as a critical risk factor in perimenopausal women. Standardized MHT can effectively improve endocrinemetabolic disorders with satisfactory safety.
