Objective To evaluate the effect of remimazolam premedication on emergence delirium （ED） in children undergoing tonsillectomy and/or adenoidectomy. Methods Children aged 3-6 years who underwent tonsillectomy and/or adenoidectomy with general anesthesia in Zhongshan Hospital Affiliated to Xiamen University from July 2023 to September 2024 were randomly divided into 0.1 mg/kg remimazolam group （group R1）, 0.2 mg/kg remimazolam group group R2） and normal saline group （group P）. Three groups were sedated preoperatively with remimazolam 0.1 mg/kg, remimazolam 0.2 mg/kg and normal saline, respectively. The primary outcome was the incidence of ED. The secondary outcomes included the parental separation anxiety scale （PSAS） score when entering the operating room, the induction compliance checklist （ICC） score at induction, the anesthetic recovery time, the incidence of rescue propofol for ED, the face, legs, activity, cry, and consolability （FLACC） score and the incidence of postoperative pain during the recovery period, the incidence of adverse reactions during the operation and postoperatively, and the incidence of negative postoperative behavioral changes （NPOBCs） at first day, 7th day, 30th day postoperatively. Results A total of 119 children completed the study, including 41 children in group R1, 38 children in group R2, and 40 children ingroup P. The incidence of ED and propofol rescue, the PSAS scores and ICC scores of group R1 and R2 were lower than that of group P （P<0.05）, and the above results in group R2 was better than those in group R1 （P<0.05）. The FLACC score, the incidence of postoperative pain, and the incidence of adverse reactions among the three groups had no difference （P>0.05）. The incidence of NPOBCs at 1st day and 7th day postoperatively in group R1 and group R2 was lower than that in group P （P<0.05）, but no difference was detected at 30th day postoperatively among the three groups （P>0.05）. Conclusion Remimazolam used for preoperative sedation could reduce the incidence of ED in children undergoing tonsillectomy and/or adenoidectomy, and had a positive effect on alleviating the preoperative anxiety and preventing NPOBCs.

BACKGROUND: The purpose of this study was to evaluate the safety and efficacy of subsequent radiotherapy (RT) following first-line treatment with durvalumab plus chemotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC). METHODS: A total of 122 patients with ES-SCLC from three hospitals during July 2019 to December 2021 were retrospectively analyzed. Inverse probability of treatment weighting (IPTW) analysis was performed to address potential confounding factors. The primary focus of our evaluation was to assess the impact of RT on progression-free survival (PFS) and overall survival (OS). RESULTS: After IPTW analysis, 49 patients received durvalumab plus platinum-etoposide (EP) chemotherapy followed by RT (Durva + EP + RT) and 72 patients received immunochemotherapy (Durva + EP). The median OS was 17.2 months vs . 12.3 months (hazard ratio [HR]: 0.38, 95% confidence interval [CI]: 0.17-0.85, P = 0.020), and the median PFS was 8.9 months vs . 5.9 months (HR: 0.56, 95% CI: 0.32-0.97, P = 0.030) in Durva + EP + RT and Durva + EP groups, respectively. Thoracic radiation therapy (TRT) resulted in longer OS (17.2 months vs . 14.7 months) and PFS (9.1 months vs . 7.2 months) compared to RT directed to other metastatic sites. Among patients with oligo-metastasis, RT also showed significant benefits, with a median OS of 17.4 months vs . 13.7 months and median PFS of 9.8 months vs . 5.9 months compared to no RT. Continuous durvalumab treatment beyond progression (TBP) prolonged OS compared to patients without TBP, in both the Durva + EP + RT (NA vs . 15.8 months, HR: 0.48, 95% CI: 0.14-1.63, P = 0.238) and Durva + EP groups (12.3 months vs . 4.3 months, HR: 0.29, 95% CI: 0.10-0.81, P = 0.018). Grade 3 or 4 adverse events occurred in 13 (26.5%) and 13 (18.1%) patients, respectively, in the two groups; pneumonitis was mostly low-grade. CONCLUSION Addition of RT after first-line immunochemotherapy significantly improved survival outcomes with manageable toxicity in ES-SCLC.

OBJECTIVE: To investigate the clinical features and prognosis of central nervous system (CNS) invasion in peripheral T-cell lymphoma (PTCL) and construct a risk prediction model for CNS invasion. METHODS: Clinical data of 395 patients with PTCL diagnosed and treated in the First Affiliated Hospital of Zhengzhou University from 1st January 2013 to 31st December 2022 were analyzed retrospectively. RESULTS: The median follow-up time of 395 PTCL patients was 24(1-143) months. There were 13 patients diagnosed CNS invasion, and the incidence was 3.3%. The risk of CNS invasion varied according to pathological subtype. The incidence of CNS invasion in patients with anaplastic large cell lymphoma (ALCL) was significantly higher than in patients with angioimmunoblastic T-cell lymphoma (AITL) (P <0.05). The median overall survival was significantly shorter in patients with CNS invasion than in those without CNS involvement, with a median survival time of 2.4(0.6-127) months after diagnosis of CNS invasion. The results of univariate and multivariate analysis showed that more than 1 extranodal involvement (HR=4.486, 95%CI : 1.166-17.264, P =0.029), ALCL subtype (HR=9.022, 95%CI : 2.289-35.557, P =0.002) and ECOG PS >1 (HR=15.890, 95%CI : 4.409-57.262, P <0.001) were independent risk factors for CNS invasion in PTCL patients. Each of these risk factors was assigned a value of 1 point and a new prediction model was constructed. It could stratify the patients into three distinct groups: low-risk group (0-1 point), intermediate-risk group (2 points) and high-risk group (3 points). The 1-year cumulative incidence of CNS invasion in the high-risk group was as high as 50.0%. Further evaluation of the model showed good discrimination and accuracy, and the consistency index was 0.913 (95%CI : 0.843-0.984). CONCLUSION The new model shows a precise risk assessment for CNS invasion prediction, while its specificity and sensitivity need further data validation.

The angiogenic response is essential for the repair of ischemic brain tissue. Integrin α6 (Itga6) expression has been shown to increase under hypoxic conditions and is expressed exclusively in vascular structures; however, its role in post-ischemic angiogenesis remains poorly understood. In this study, we demonstrate that mice with endothelial cell-specific knockout of Itga6 exhibit reduced neovascularization, reduced pericyte coverage on microvessels, and accelerated breakdown of microvascular integrity in the peri-infarct area. In vitro, endothelial cells with ITGA6 knockdown display reduced proliferation, migration, and tube-formation. Mechanistically, we demonstrated that ITGA6 regulates post-stroke angiogenesis through the PI3K/Akt-eNOS-VEGFA axis. Importantly, the specific overexpression of Itga6 in endothelial cells significantly enhanced neovascularization and enhanced the integrity of microvessels, leading to improved functional recovery. Our results suggest that endothelial cell Itga6 plays a crucial role in key steps of post-stroke angiogenesis, and may represent a promising therapeutic target for promoting recovery after stroke.

Objective To analyze the predictive value of the serum amyloid A/C-reactive protein ratio(SAA/CRP),lactate dehydrogenase(LDH),and chitinase-40(YKL-40)combined with conventional influencing factors for the prognosis of children with refractory mycoplasmal pneumonia(RMPP).Methods A retrospective study was conducted on 180 children with RMPP admitted to the First People's Hospital of Nanyang from January to December 2023,serving as study group,and 90 children with general mycoplasmal pneumonia(GMPP)as control group.The clinical data of the two groups,including age,gender,and serum levels of SAA/CRP,LDH,and YKL-40,were compared.On the day of admission,the disease severity of the children in study group was assessed and divided into mild(n=102)and severe(n=78)groups.After treatment,they were further categorized into poor prognosis(n=52)and good prognosis(n=128)groups based on the occurrence of adverse events.The levels of serum SAA/CRP,LDH,and YKL-40 were compared between mild-case and severe-case children in study group,as well as between children with good and poor prognosis.A binary logistic regression model was used to analyze the influencing factors for poor prognosis in children with RMPP.Receiver operating characteristic(ROC)curve was used to evaluate the predictive value of serum SAA/CRP,LDH,and YKL-40 for the prognosis of children with RMPP.Conventional influencing factors[disease severity,oxygen therapy duration,pneumonia severity index(PSI)score,and acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score]were used as the conventional prediction scheme,and the conventional prediction scheme combined with the levels of serum SAA/CRP,LDH,and YKL-40 was used as the new prediction scheme.The predictive values of the two prediction schemes for the prognosis of children with RMPP were compared.Results The levels of serum SAA/CRP,LDH,and YKL-40 in study group were higher than those in control group(P＜0.05),and the levels of serum SAA/CRP,LDH,and YKL-40 in children with severe RMPP were higher than those in children with mild RMPP(P＜0.05).In study group,the proportion of children with pleural effusion,the proportion of severe-case disease severity,oxygen therapy duration,PSI score,APACHE Ⅱ score,and the levels of serum SAA/CRP,LDH,and YKL-40 in children with poor prognosis were higher than those in children with good prognosis(P＜0.05).Binary logistic regression analysis showed that disease severity,oxygen therapy duration,PSI score,APACHE Ⅱ score,and the levels of serum SAA/CRP,LDH,and YKL-40 were all factors affecting poor prognosis in children with RMPP(P＜0.05).The areas under the curves(AUCs)of serum SAA/CRP,LDH,and YKL-40 for predicting the prognosis of children with RMPP were 0.756,0.749,and 0.734,respectively.The AUC of the new prediction scheme was 0.945,which was significantly higher than that of the conventional prediction scheme(AUC=0.859),with a statistically significant difference(P=0.011).Conclusion Serum SAA/CRP,LDH,and YKL-40 levels combined with the conventional prediction scheme have a high predictive efficacy for the prognosis of children with RMPP.

Objective To verify the accuracy of a Non-Contact Sleep Monitoring Mattress(NCSMM)based on body movement during sleep in assessing sleep quality of patients before neurosurgery in order to provide a more portable and efficient assessment tool for clinical staff.Methods A single-arm trial was conducted on 114 inpatients admitted in our department selected with convenience sampling.Sleep quality data of 1 night were collected through 5 sleep quality assessment tools,including NCSMM,polysomnography(PSG),Patient-Reported Outcome Measurement Information System(PROMIS)Sleep Disturbance scale,Richards-Campbell Sleep Scale(RCSQ),and a wearable device(smart watch for body movements and sleep quality monitoring).The sleep efficiency(≤85%)obtained by PSG was used as the diagnostic standard for sleep disorders.The area under the receiver operating characteristic curve(AUC),sensitivity,specificity,positive predictive value,negative predictive value,and Youden index were calculated for the other 4 tools to evaluate and compare their diagnostic effectiveness.Results The AUC value for NCSMM,PROMIS,RCSQ and smart watch was 0.788(95%CI:0.687～0.888,P<0.001),0.664(95%CI:0.543～0.784,P=0.02),0.723(95%CI:0.600～0.846,P=0.001)and 0.750(95%CI:0.654～0.846,P<0.001),respectively.The diagnostic accuracy rate was 0.774,0.559,0.742 and 0.602,with corresponding Youden index value of 0.488,0.321,0.456,and 0.459.NCSMM demonstrated the best AUC value,sensitivity and Youden index when compared with the other 3 tools.Conclusion NCSMM shows high accuracy in assessing sleep quality in pre-neurosurgery inpatients,and it is a viable portable and efficient assessment tool in clinical practice.

Arsenic is a semi-metal,and lipid-soluble arsenic compounds are one of the widespread forms in the environment and food chain,but there is a lack of standards for lipid-soluble arsenic compounds,which is one of the bottlenecks in the current analytical detection and toxicological studies of organic arsenic.In this study,four saturated arsenic-containing hydrocarbons,AsHC 318,AsHC 332,AsHC 346,and AsHC 374(The number is relative molecular mass),were successfully synthesized in three steps by using dimethylarsinic acid,potassium iodide,sodium hydroxide,and four brominated alkanes(1-Bromotetradecane,1-bromopentadecane,1-bromohexadecane,and 1-bromooctadecane)as raw materials.The structures of these four saturated arsenic-containing hydrocarbons were characterized by proton nuclear magnetic resonance(1H NMR)spectroscopy,13C nuclear magnetic resonance(13C NMR)spectroscopy,and high-resolution mass spectrometry(HR-MS).The yields of the method were 8%-10%,and the synthesized compounds could be used in subsequent toxicity evaluation experiments to assess the toxic effects and mechanisms of action of arsenic-containing hydrocarbons.This study provided an effective method for synthesis of arsenic-containing hydrocarbons,enriching the synthesis methods of arsenic-containing hydrocarbons,and provided raw materials for the subsequent toxicological studies of arsenic-containing hydrocarbons.
