Objective To investigate the effect of esketamine on postoperative depression in frail elderly patients undergoing thoracoscopic radical resection of lung cancer.Methods A total of 88 frail elderly patients undergoing elective thoracoscopic radical resection of lung cancer were assigned randomly(using a randomization table)and in a double-blind way(blinding applies to both researchers and patients)to an esketamine group(Esk group,n=44)and a normal saline group(NS group,n=44).In the Esk group,0.25 mg/kg esketamine was injected intravenously during anesthesia induction,followed by continuous infusion of esketamine at 0.125 mg/kg per hour until 20 min before the end of surgery.In the NS group,equivalent volumes of normal saline were administered using the same method.The primary outcome was the score for the 17-item Hamilton Rating Scale for Depression(HAMD-17)on days 7 and 30 after surgery.The secondary outcomes included sleep quality and cognitive function.Sleep quality was assessed using the numerical rating scale(NRS)on days 1,3,and 7 after surgery and the Pittsburgh Sleep Quality Index(PSQI)on day 30 after surgery.Cognitive function was assessed using the Mini-Mental State Examination(MMSE)on days 1,3,7,and 30 after surgery.The other indicators included the levels of serum brain-derived neurotrophic factor(BDNF),5-hydroxytryptamine(5-HT),S100β protein,and neuron specific enolase(NSE)at 24 hours(T1),48 hours(T2),and 72 hours(T3)after surgery,as well as perioperative data and postoperative safety outcomes.Results Three patients were excluded from the Esk group and the NS group,respectively,and eventually,41 patients in each group were included in the statistical analysis.There were no statistically significant differences between the two groups in terms of age,sex,body mass index,American Society of Anesthesiologists(ASA)classification,comorbidities,educational attainment,and the scores for HAMD-17,PSQI,and MMSE 1 day before surgery(P＞0.05).Concerning the primary outcome,compared with those of the NS group,the HAMD-17 scores of patients in the Esk group were significantly lower at 7 days(median[P25,P75])(7[6,8]vs.7[6,12],P=0.045)and 30 days(6[6,7]vs.7[6,9],P=0.020)after surgery.Concerning the secondary outcomes,compared with those of the NS group,the sleep NRS scores of patients in the Esk group were significantly lower at 1,3,and 7 days after surgery(P＜0.01),and the MMSE scores were significantly higher(P＜0.05).Concerning the other indicators,compared with those of the NS group,the concentrations of serum BDNF and 5-HT in the Esk group were significantly higher(P＜0.05 or 0.01)at T1-T3,while the content of S100β was significantly lower(P＜0.01)at T1-T3;the levels of serum NSE were significantly lower at T1 and T2(P＜0.01);the consumption of propofol,sufentanil,remifentanil,and sevoflurane during surgery in the Esk group was significantly reduced(P＜0.05 or 0.01);the incidence of postoperative nausea/vomiting and hyperalgesia was significantly lower(P＜0.01);the duration of postoperative mechanical ventilation,length-of-stay in postanesthesia care unit(PACU),and postoperative length-of-stay in the hospital were significantly shorter(P＜0.01).Conclusion Esketamine can improve the postoperative depressive state,sleep quality,and cognitive function in frail elderly patients undergoing thoracoscopic radical resection of lung cancer.

Analyzing the spatial distribution pattern and formation factors of medicinal plant resources can provide a scientific basis for the protection and development of traditional Chinese medicine(TCM) resources. This study is based on the survey data of medicinal plant resources in 104 county-level administrative regions of Anhui province in the Fourth National Survey of TCM Resources. The global spatial autocorrelation analysis, trend surface analysis, local spatial autocorrelation analysis, hotspot analysis, and a geodetector were employed to analyze the spatial distribution pattern of medicinal plant richness, and its relationship with natural factors was explored. The results can provide a basis for the formulation of development strategies such as the protection and utilization of TCM resources, as well as offer a scientific foundation for the establishment of regional planning schemes for TCM resources in Anhui province. The results indicated that the richness of medicinal plant resources in Anhui province had significant spatial heterogeneity, exhibiting highly clustered distribution characteristics. Cold spots and hot spots presented clustered distribution patterns, with cold spots mostly located north of the Huaihe River and hot spots south of the Yangtze River. Overall, the distribution of medicinal plant resources in Anhui province showed an overall trend of high in the south and low in the north, which was consistent with the overall geomorphic trend of this province. In addition, natural factors such as altitude, precipitation, and vegetation type played an important role in the diversity and spatial distribution pattern formation of medicinal plant resources. The extraction and analysis of the spatial distribution characteristics of natural factors in cold and hot spot regions discovered that the heterogeneity of eco-environments constituted a fundamental condition for the formation of species diversity.

Objective To investigate the toxicokinetic differences of 3,4-methylenedioxy-N-methylamphetamine(MDMA)and its metabolite 4,5-methylene dioxy amphetamine(MDA)in rats af-ter single and continuous administration of MDMA,providing reference data for the forensic identifica-tion of MDMA.Methods A total of 24 rats in the single administration group were randomly divided into 5,10 and 20 mg/kg experimental groups and the control group,with 6 rats in each group.The ex-perimental group was given intraperitoneal injection of MDMA,and the control group was given intraperi-toneal injection of the same volume of normal saline as the experimental group.The amount of 0.5 mL blood was collected from the medial canthus 5 min,30 min,1 h,1.5 h,2 h,4 h,6 h,8 h,10 h,12 h after administration.In the continuous administration group,24 rats were randomly divided into the experi-mental group(18 rats)and the control group(6 rats).The experimental group was given MDMA 7 d by continuous intraperitoneal injection in increments of 5,7,9,11,13,15,17 mg/kg per day,respectively,while the control group was given the same volume of normal saline as the experimental group by in-traperitoneal injection.On the eighth day,the experimental rats were randomly divided into 5,10 and 20 mg/kg dose groups,with 6 rats in each group.MDMA was injected intraperitoneally,and the con-trol group was injected intraperitoneally with the same volume of normal saline as the experimental group.On the eighth day,0.5 mL of blood was taken from the medial canthus 5 min,30 min,1 h,1.5 h,2 h,4 h,6 h,8 h,10 h,12 h after administration.Liquid chromatography-triple quadrupole tandem mass spectrometry was used to detect MDMA and MDA levels,and statistical software was employed for data analysis.Results In the single-administration group,peak concentrations of MDMA and MDA were reached at 5 min and 1 h after administration,respectively,with the largest detection time limit of 12 h.In the continuous administration group,peak concentrations were reached at 30 min and 1.5 h af-ter administration,respectively,with the largest detection time limit of 10 h.Nonlinear fitting equations for the concentration ratio of MDMA and MDA in plasma and administration time in the single-administration group and continuous administration group were as follows:T=10.362C-1.183,R2=0.974 6;T=7.397 3C-0.694,R2=0.961 5(T:injection time;C:concentration ratio of MDMA to MDA in plasma).Conclusions The toxicokinetic data of MDMA and its metabolite MDA in rats,obtained through single and continuous administration,including peak concentration,peak time,detection time limit,and the relationship between concentration ratio and administration time,provide a theoretical and data foundation for relevant forensic identification.

Objective:To investigate the incidence of radiation pneumonitis (RP) induced by 125I seed implantation for the treatment of malignant lung tumors and analyze related dosimetric parameters. Methods:A retrospective analysis was conducted on 31 cases of malignant lung tumors treated with 125I seed implantation from January 2017 to December 2022 at Hebei Provincial Tumor Radioactive Seeds Implantation Diagnosis and Treatment Center. These cases consisted of eight patients with squamous cell carcinoma, 10 patients with adenocarcinoma, and 13 patients with metastatic cancer in other sites. At 1-6 months after treatment, these patients received postoperative chest CT scans, with the efficacy evaluated based on the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1), including the objective response rate (ORR) and the disease control rate (DCR). The efficacy of RP was evaluated using the Radiation Therapy Oncology Group (RTOG) criteria. Postoperative dosimetric parameters, including D90 (minimum peripheral dose received by 90% of the target volume), V8 (percentage of lung volume receiving 8 Gy), V32 (percentage of lung volume receiving 32 Gy), and Dmean (mean radiation dose) of the affected lung, were statistically analyzed. The relationships of the RP occurrence with postoperative D90, V8, V32, and Dmean were analyzed by comparison with relevant external radiotherapy data, to identify the parameters that are correlated closely with RP occurrence. Results:All the patients underwent successful surgeries. The postoperative efficacy evaluation after six months showed complete response (CR) in 11 cases, partial response (PR) in 11 cases, stable disease (SD) in eight cases, and progressive disease (PD) in one case, with an overall response rate (ORR) of 71.0%, and a disease control rate (DCR) of 96.8%. Three patients suffered RP, with an incidence rate of 9.7%. Postoperative V8, V32, and Dmean could not serve as predictive indicators for RP. Follow-up observation revealed that three RP cases (3/5) exhibited postoperative D90 exceeding 170 Gy and no RP cases (0/26) showed postoperative D90 below 170 Gy. Conclusions:In the treatment of malignant lung tumors with 125I seed implantation, there is a certain correlation between RP and postoperative D90, while there is no correlation between it and V8, V32, and Dmean.
