Objective To investigate the influence of intravenous esketamine infusion on anesthetic effect and awakening quality in elderly patients undergoing laparoscopic surgery for prostate cancer.Methods One hundred and twenty patients with laparoscopic radical prostatectomy were selected and divided into the esketamine group(group E)and control group(group C)by the random number table method,60 ca-ses in each group.The group E used esketamine for anesthesia induction and maintenance,while the group C received the same amount of physiological saline at the same time during operation process as control.The es-ketamine pumping infusion or normal saline in the two groups was stopped at 30 min before operation end.In addition,the types and doses of other drugs used during the induction and maintenance phase of anesthesia were identical between the two groups.The use total amounts of anesthetic drugs during perioperative period were recorded.The heart rate(HR)and mean arterial pressure(MAP)were recorded before operation(T1),instantly before tracheal intubation(T2),at 1 min after tracheal intubation(T3),1 h during surgery(T4),end of skin suture(T5),and 5 min after extubation(T6)in the two groups respectively;the anesthetic recovery time after extubation was recorded.The Riker sedation and restlessness score was used to conduct the agita-tion evaluation,the incidence rates of agitation and bucking and the resuscitation room stay time were recor-ded.The pain VAS score was used to conduct the pain evaluation in the patients.The incidence rates of ad-verse events such as respiratory depression,shiverring,nausea,vomiting,drowsiness after extubation were re-corded.Results The perioperative doses of resutanil and propofol in the group E were significantly lower than those in the group C,and the difference was statistically significant(P＜0.05).HR and MAP at T2 in the group E were higher than those in the group C,while HR and MAP at T3 in the group E were lower than those in the group C.The recovery time after extubation in the group E was longer than that in the group C,the agitation incidence rate,acute bucking incidence rate and VAS score were lower,the stay time in the recov-ery room was shorter.The incidence rate of drowsiness in the group E was significantly higher than that in the group C(P＜0.05).The incidence rates of other adverse events had no statistical differnece(P＞0.05).Con-clusion Esketamine is safe and effective in the elderly patients with laparoscopic prostate cancer surgery,which is conducive to stabilize the hemodynamic parameters and reduce the incidence rate of agitation and buc-king.

Objective:To investigate the predictive value of neutrophil extracellular traps (NETs) on the prognosis of patients with epidermal growth factor receptor (EGFR) wild-type lung adenocarcinoma.Methods:A total of 132 surgical paraffin specimens of EGFR wild-type lung adenocarcinoma diagnosed at the Tumor Hospital Affiliated to Xinjiang Medical University from January 2016 to December 2023 and 12 pairs of cancer and paracancerous fresh tissues from patients with EGFR wild-type lung adenocarcinoma diagnosed in March-July 2024 were collected with their clinical information. Western blotting and immunofluorescence were used to detect the expression levels of citrullinated histone H3 (CitH3) and myeloperoxidase (MPO) in cancerous and paraneoplastic tissues. Immunohistochemistry was used to detect the infiltration of PD-L1, CD4 + T cells and CD8 + T cells in the tumors. The clinical and prognostic correlations between NETs and EGFR wild-type lung adenocarcinoma patients were analyzed. Results:The expression of MPO ( P＜0.001) and CitH3 ( P=0.009) was significantly increased in the tumors compared with the paracancerous tissues. The rate of high expression of NETs in cancer tissues was higher in patients with EGFR wild-type lung adenocarcinoma who were in stage Ⅲ and Ⅳ, with lymph node metastasis, distant metastasis, pleural invasion, high expression of Ki-67, low expression of CD8 + T, and lowered lymphocyte counts when compared to paraneoplastic tissues ( P＜0.05). Patients were stratified based on TNM stage Ⅱb for prognostic analysis. Kaplan-Meier univariate analysis showed that the median overall survival (OS) (stage Ⅰ to Ⅱb: 47 vs 87 months; stage Ⅲ to Ⅳ: 27 months vs not reach) and the median disease-free survival (DFS) (stage Ⅰ to Ⅱb: 42 vs 78 months; stage Ⅲ to Ⅳ: 18 vs 39 months) of patients with high expression of NETs in stage Ⅰ to II b and stage Ⅲ to Ⅳ were lower than those with low expression (stage Ⅰ to Ⅱb: OS, P＜0.001; DFS, P＜0.001; stage Ⅲ to Ⅳ: OS, P=0.001; DFS, P=0.022). The OS (stage Ⅰ to Ⅱb: HR=3.513, 95% CI: 1.966-6.277, P＜0.001; stage Ⅲ to Ⅳ: HR=3.215, 95% CI: 1.324-7.806, P=0.010) and the DFS (stage Ⅰ to Ⅱb: HR=2.478 ,95% CI: 1.396-4.400, P=0.002; stage Ⅲ to Ⅳ: HR=2.248, 95% CI: 1.089-4.638, P=0.028) in the group with high expression of NETs in either stage Ⅰ to Ⅱb or stage Ⅲ to Ⅳ were significantly shorter than those in the group with low expression. Conclusion:The EGFR wild-type lung adenocarcinoma patients with high expression of NETs have relatively shorter DFS and OS, which are independent risk factors for the prognosis of patients with EGFR wild-type lung adenocarcinoma, and are likely to be the potential biomarkers for the diagnosis and treatment of EGFR wild-type lung adenocarcinoma.

Objective:To evaluate the changes in left ventricular structure and function in pregnant women with different severities of hypertensive disorders of pregnancy（HDP）using conventional echocardiographic parameters，strain，and tissue-tracking mitral annulus displacement（TMAD）parameters，and to validate and compare the application value of strain and TMAD parameters.Methods:A total of 148 singleton pregnant women with HDP and 100 healthy pregnant women（HP group）who attended the Third Affiliated Hospital of Zhengzhou University from October 2023 to July 2024 were selected. Conventional echocardiographic parameters，strain，and TMAD parameters were collected. Based on the severity of the disease，HDP patients were divided into the gestational hypertension group（GH group， n=49），non-severe preeclampsia group（NSPE group， n=35），and severe preeclampsia group（SPE group， n=64）. The differences in various parameters between the HP，GH，NSPE，and SPE groups were compared. The correlation between the displacement ratio of the midpoint of the mitral valve annulus in the apical 4-chamber（AP4 Midpt%），the displacement ratio of the midpoint of the mitral valve annulus in the apical 2-chamber（AP2 Midpt%）and left ventricular global longitudinal strain（LVGLS）were analyzed，and ROC curves were plotted to analyze and compare the diagnostic efficacies of LVGLS，AP4 Midpt% and AP2 Midpt% for left ventricular function changes in HDP pregnant women. Results:① The analysis revealed no statistically significant differences in maternal age and height between the HP group and the HDP subgroups（all P>0.05）. In contrast，statistically significant differences were observed in gestational age，systolic blood pressure，diastolic blood pressure，body mass index，and body surface area（all P<0.05）. Additionally，significant differences were noted in left ventricular mass，left ventricular interventricular septum thickness at end-diastole，left ventricular posterior wall thickness at end-diastole，left ventricular end-diastolic dimension，left ventricular end-systolic dimension，left ventricular end-diastolic volume，left ventricular end-systolic volume，and stroke volume between the HP group and the HDP subgroups（all P<0.05），while the difference in left ventricular ejection fraction was not statistically significant（ P>0.05）. ② Significant differences were identified in strain and TMAD parameters between the HP group and the HDP subgroups（all P<0.05），with LVGLS，AP4 Midpt% and AP2 Midpt% exhibited the largest effect sizes（ η p2=0.457，0.453，0.351）. A progressive decline in strain and TMAD parameters was observed as the severity of HDP increased. ③ There were strong positive correlations between AP4 Midpt%，AP2 Midpt% and LVGLS（ r=0.752，0.747；all P<0.001）. ④ LVGLS，AP4 Midpt% and AP2 Midpt% all demonstrated significant diagnostic efficacies for changes in left ventricular function in HDP（AUC=0.840，0.847，0.791），and the differences in AUC among the 3 curves were not statistically significant（all P>0.05）.⑤ The success rate of collecting TMAD parameters was significantly higher than that of strain parameters（99.24% vs. 93.58%， P<0.001）. Conclusions:As the severity of the disease worsens，the changes of left ventricular structure and function in pregnant women with HDP become more and more significant. Both strain and TMAD parameters can early and sensitively identify the subclinical damage of left ventricular systolic function in HDP pregnant women，and both of them have the same diagnostic value. TMAD parameters can be used as a reliable substitute parameter of LVGLS in HDP pregnant women.
