Background: Intraoperative hypercapnia reduces the time to emergence from volatile anesthetics, but few clinical studies have explored the effect of hypercapnia on the emergence time from intravenous (IV) anesthesia. We investigated the effect of inducing mild hypercapnia during the recovery period on the emergence time after total IV anesthesia (TIVA). Methods: Adult patients undergoing transurethral lithotripsy under TIVA were randomly allocated to normocapnia group (end-tidal carbon dioxide [ETCO2] 35–40 mmHg) or mild hypercapnia group (ETCO2 50-55 mmHg) during the recovery period. The primary outcome was the extubation time. The spontaneous breathing-onset time, voluntary eye-opening time, and hemodynamic data were collected. Changes in the cerebral blood flow velocity in the middle cerebral artery were assessed using transcranial Doppler ultrasound. Results: In total, 164 patients completed the study. The extubation time was significantly shorter in the mild hypercapnia (13.9 ± 5.9 min, P = 0.024) than in the normocapnia group (16.3 ± 7.6 min). A similar reduction was observed in spontaneous breathing-onset time (P = 0.021) and voluntary eye-opening time (P = 0.008). Multiple linear regression analysis revealed that the adjusted ETCO2 level was a negative predictor of extubation time. Middle cerebral artery blood flow velocity was significantly increased after ETCO2 adjustment for mild hypercapnia, which rapidly returned to baseline, without any adverse reactions, within 20 min after extubation. Conclusions Mild hypercapnia during the recovery period significantly reduces the extubation time after TIVA. Increased ETCO2 levels can potentially enhance rapid recovery from IV anesthesia.

Approximately one-third of stroke patients experience post-stroke cognitive impairment （PSCI）， which significantly impacts their quality of life and survival time. The clinical evaluations of PSCI mainly rely on subjective neurophysiological scales due to its complex pathogenesis and lack of reliable， objective diagnostic tools. However， electroencephalogram （EEG） and magnetic resonance imaging （MRI） could provide objective indicators for diagnosis of PSCI. Based on EEG， MRI and EEG-MRI fusion， this article reviews recent advances in the central mechanisms of PSCI， focusing on changes in brainwave spectrum， brain structure， brain network etc.， in order to explore the clinical values of EEG and MRI in predicting and diagnosing PSCI， enhance the understanding of its pathogenesis and provide a basis for accurate clinical diagnosis.

Objective To compare the efficacy of renal proximal renal artery denervation(pRDN)and full-length renal artery denervation(fRDN)for treatment of hypertension.Methods Fifty-six hypertensive patients were enrolled and randomly assigned to full-length renal artery denervation group(n=25)and proximal renal artery denervation group(n=31).After the procedure,24-hour ambulatory blood pressure monitoring(24 h-ABPM)at 6 months and office blood pressure at 12 months was recorded for statistical analysis.Results The blood pressure at follow-up reduced significantly in both groups,while there was no significant difference between groups.The baseline office blood pressure in fRDN group and pRDN group was(180±15)/(104±10)mmHg and(180±12)/(103±8)mmHg,respectively,which decreased to(142±9)/(82±7)mmHg and(143±10)/(83±6)mmHg at 12 months postoperatively(P＜0.001 within groups and P＞0.05 between groups).The baseline 24 h-ABPM in the two groups was(162±13)/(95±8)mmHg and(160±12)/(94±8)mmHg,respectively,which decreased to(142±11)/(83±7)mmHg and(141±8)/(81±7)mmHg at 6 months postoperatively(P＜0.001 within groups and P＞0.05 between groups).However,there was no significant difference in the reduction of office blood pressure and ambulatory blood pressure between the two groups.No treatment-related adverse events were observed.Conclusions pRDN has similar antihypertensive effect to fRDN.

In the face of the severe challenges posed by chronic illnesses, patients not only experience negative emotions due to their condition but also undergo positive transformations, such as a sense of benefit finding. This article summarizes the theoretical foundations, assessment tools, influencing factors, and intervention measures related to benefit finding among chronic disease patients. The aim is to provide references for healthcare professionals to develop and implement personalized psychological nursing care for chronic disease patients.

With the application of accelerated rehabilitation surgery mode in metabolic bariatric surgery, the postoperative hospital stay of patients is gradually shortened, but it also leads to the lack of postoperative knowledge of patients after discharge. Adequate guidance on discharge readiness is beneficial for improving the self-management ability of patients and improving dietary, medication and exercise compliance. This paper reviews the status quo, assessment tools, influencing factors and intervention measures of discharge readiness of patients undergoing metabolic bariatric surgery, in order to provide references and ideas for developing discharge readiness evaluation tools and related studies for patients undergoing metabolic bariatric surgery in China.

To clarify the structural characteristics of virus communities carried by primates in the Guangdong region,and evaluate the risk of the important zoonotic virus monkeypox virus(MPXV)being introduced into China through artificially do-mesticated primates,this study conducted metagenomic research on artificially domesticated primates and performed screening for MPXV.Primate samples were collected from 20 wildlife rescue centers or zoos in 14 prefecture level cities in Guangdong Province,and the structural characteristics of virus communities carried by artificially domesticated primates were identified through Illumina sequencing.Fluorescence quantitative PCR detection of MPXV excluded the risk of MPXV being introduced through artificially domesticated primates in Guangdong Prov-ince.A total of 489 oral and pharyngeal swabs and feces from primates were collected.High-throughput sequencing indicated that the viral group structure in the feces of artificially domesti-cated primates in the Guangdong region is complex and shows regional differences.Members of Alphaflexiviridae and Vir-gaviridae,followed by members of Parvoviridae and Genomo-viridae,had the highest abundance.Subsequently,fluorescence quantitative PCR results showed that all primates from wildlife rescue centers or zoos in Guangdong Province were MPXV neg-ative.This study provides the first description of the complex viral structure characteristics of artificially domesticated primates in the Guangdong region,and elucidates the differences in vi-ral communities among artificially domesticated primates in different regions.Our findings suggested that the risk of zoonotic diseases caused by artificially domesticated primates in Guangdong Province is extremely low,and the risk of MPXV being in-troduced into China through artificially domesticated primates in Guangdong Province is zero.

Ischemic stroke is a neurological disease that damages brain tissue as a result of an insufficient blood supply to the brain,due to blockage or stenosis of the brain vessels.Increasing evidence has indicated that the Wnt/β-catenin signaling pathway plays an important role in the pathophysiological response to the occurrence and development of ischemic stroke.Programmed cell death includes many forms,such as apoptosis,necrotic apoptosis,pyroptosis,autophagy,PANoptosis,and ferroptosis.In this review,we elucidate the characteristics of these different modes of cell death and their cross-talk relationships with each other,and systematically outline the role of Wnt/β-catenin signaling pathways in the intervention of different cell death modes in ischemic stroke,with the aim of providing references for future clinical and basic research studies.
