BACKGROUND Hypertensive cerebral hemorrhage(HCH),the most common chronic diseases,has become a topic of global public health discussions.AIM To investigate the role of rehabilitative nursing interventions in optimizing the postoperative mental status recovery phase and to provide clinical value for future rehabilitation of patients with HCH.METHODS This randomized controlled study included 120 patients with cerebral HCH who were contained to our neurosurgery department between May 2021–May 2023 as the participants.The participants have randomly sampled and grouped into the observation and control groups.The observation group received the rehabilitation nursing model,whereas the control group have given conventional nursing.The conscious state of the patients was assessed at 7,14,21,and 30 d postoperatively.After one month of care,sleep quality,anxiety,and depression were compared between the two groups.Patient and family satisfaction were assessed using a nursing care model.RESULTS The results showed that the state of consciousness scores of the patients in both groups significantly increased(P<0.05)after surgical treatment.From the 14th day onwards,differences in the state of consciousness scores between the two groups of patients began to appear(P<0.05).After one month of care,the sleep quality,anxiety state,and depression state of patients were significantly better in the observation group than in the control group(P<0.05).Satisfaction with nursing care was higher in the observation group than in the control group(P<0.05).CONCLUSION The rehabilitation nursing model has a more complete system compared to conventional nursing,which can effectively improve the postoperative quality of life of patients with cerebral hemorrhage and improve the efficiency of mental state recovery;however,further analysis and research are needed to provide more scientific evidence.

The abnormal activation of HER family kinase activity is closely related to the development of human malignancies.In this study,we used HER kinases as targets for the treatment of nasopharyngeal carcinoma(NPC)and explored the anti-tumor effects of the novel pan-HER inhibitor HM781-36B,alone or in combination with cisplatin.We found that HER family proteins were positively expressed in tumor tissues of some NPC patients,and the high levels of those proteins were significantly related to poor prognosis.HM781-36B inhibited NPC in vitro and in vivo.HM781-36B exerted synergistic effects with cisplatin on inhibiting proliferation and promoting apoptosis of NPC cells.In NPC xenograft models in nude mice,HM781-36B and cisplatin synergistically inhibited tumor growth.Downregulating the activity of HER family proteins and their downstream signaling pathways and regulating tumor microenvironment may explain the synergistic anti-tumor effects of HM781-36B and cisplatin.In conclusion,our study provides evidence for HER family proteins as prognostic biomarkers and potential therapeutic targets for NPC.The pan-HER inhibitor HM781-36B alone or in combination with cisplatin represents promising therapeutic effects for the treatment of NPC patients,which provides a new idea for the comprehensive treatment of NPC.

N,P co-doped porous graphene with high electrochemical properties obtained via the laser induction of cellulose nanofibrils

引用

Chinese Journal of Chemical Engineering 2022年第7期35卷 31-38页

作者： Jie wei weiwei yang Shuai Jia Jie wei Ziqiang Shao Beijing Engineering Research Center of Cellulose and Its Derivatives School of Materials Science and EngineeringBeijing Institute of TechnologyBeijing 100081China

Cellulose and its derivatives are natural materials with high carbon contents, but it is challenging to convert their carbon into high value-added carbonaceous materials(e.g., graphene). Here, an approach to convert the carbon in cellulose into N, P co-doped porous graphene(LIG) materials via laser induction is proposed. Cellulose nanofibrils(CNFs), a cellulose derivative with high dispersion uniformity and abundant surface hydroxyl groups, were easily formed on a bulk substrate(thickness ≥5 mm) containing ammonium polyphosphate(APP). Then, a 10.6 μm CO2 laser was used to scribe for 1–5 passes on the CNFs/APP substrate under an ambient environment to produce N, P co-doped porous LIG. Upon increasing the number of laser scribing passes, the IG/IDof LIG first increased and then decreased, reaching a maximum of 1.68 at 4 passes. The good pore structure and low resistance also showed that 4 laser passes were ideal. Besides, the N, P co-doped LIG also showed excellent electrochemical performance, with a specific capacitance of 221.4 FF·g^(-1) and capacitance retention of 89.9%. This method exploits the advantages of nanocellulose and overcomes the difficulties associated with directly compounding cellulosic materials, providing a method for the further development of biomass nanomaterials.

Synergistic double-atom catalysts of metal-boron anchored on g-C_(2)N for electrochemical nitrogen reduction:Mechanistic insight and catalyst screening

Journal of Energy Chemistry 2023年第5期80卷 350-360,I0009页

作者： yang Li wei An College of Chemistry and Chemical Engineering Shanghai University of Engineering ScienceShanghai 201620China

The rational design of a novel catalytic center with a sound basis remains both challenging and rewarding for the electrochemical reduction of N2(e NRR),which has provided a feasible route for achieving clean and sustainable NH3production under ambient conditions.Herein,using density functional theory calculations,we demonstrate that hybrid metal(M)-boron(B)double-atom catalysts(DACs)embedded in gC_(2)N substrate(M-B@C_(2)N,M=3d,4d and 5d transition metals)can achieve both high catalytic activity and high selectivity in e NRR.The proposed M-B@C_(2)N DACs have exhibited impressive feasibility and stability thanks to the resilient and robust C_(2)N substrate with abundant pyridinic N atoms distributed among right-sized pore structures.Our results reveal that like the metal center,the embedded B atom can actively involve in N≡N bond activation viaπ*-backdonation mechanism concomitant with the substantial charge transfer to adsorbed*N2,leading to sizable NAN bond elongation.Accordingly,both adsorption energy and NAN bond length of*N2can be employed as catalytic descriptors for predicting e NRR activity in terms of the limiting potentials(UL).Using high-throughput screening method,we found that six M-B@C_(2)N candidates have stood out as the outstanding electrocatalysts for driving e NRR,namely,M=Ti(UL=0 V),Mo(UL=0 V),Nb(UL=-0.04 V),W(UL=-0.23 V),Zr(UL=-0.26 V),V(UL=-0.28 V).The underlying origin is attributed to the balanced and constrained N-affinity of M-B dual site working in synergy,which can thus be used as one important guide of catalyst design.

Radio map is an advanced technology that mitigates the reliance of multiple-input multiple-output(MIMO)beamforming on channel state information(CSI).In this paper,we introduce the concept of deep learning-based radio map,which is designed to be generated directly from the raw CSI data.In accordance with the conventional CSI acquisition mechanism of MIMO,we first introduce two baseline schemes of radio map,i.e.,CSI prediction-based radio map and throughput predictionbased radio map.To fully leverage the powerful inference capability of deep neural networks,we further propose the end-to-end structure that outputs the beamforming vector directly from the location information.The rationale behind the proposed end-to-end structure is to design the neural network using a task-oriented approach,which is achieved by customizing the loss function that quantifies the communication quality.Numerical results show the superiority of the task-oriented design and confirm the potential of deep learning-based radio map in replacing CSI with location information.

Metal-organic frameworks(MOFs)have attracted widespread attention due to their regular structures,multiple material centers,and various ligands.They are always considered as one kind of ideal templates for developing highly sensitive and selective gas sensors.In this study,the advantages of MOFs with the high specific surface area(71.9891 m^(2)·g^(-1))and uniform morphology were fully utilized,and urchin-like SnO_(2) nanowires were obtained by the hydrothermal method followed by the calcination using Sn-MOFs consisting of the ligand of C_(9)H_(6)O_(6)(H_(3)BTC)and Sn/Ce center ions as sacrificial templates.This unique urchin-like nanowire structure facilitated gas diffusion and adsorption,resulting in superior gas sensitivity.A series of Ce-doped SnO_(2) nanowires with different doping ratios were synthesized,and their gas sensing properties towards formaldehyde were studied.The resulted Ce-SnO_(2) was revealed to have high sensitivity(201.2 at 250℃),rapid response(4 s),long-term stability,and good repeatability for formaldehyde sensing,and the gas sensing mechanism of Ce-SnO_(2) exposed to formaldehyde was also systematically discussed.

Nanozymes with high enzyme-like catalytic activity have been recognized as promising alternatives for nature enzymes and exhibit great potentials in biodetection,disease diagnosis and treatment. Metal nanozyme is an important member of the nanozyme family. When metal nanozymes are controllably regulated by compositions,sizes, morphologies, crystal defects, surface states or stimulated by diversified external fields, they will acquire unique geometric and electronic structures and exhibit various physical/chemical properties in catalytic behaviors.Although significant progress has been made in metal nanozymes, there is still large space for further improving the catalytic efficiency, developing the synthetic process for large-scale production, facilitating the clinical transformation and exploring the untapped applications.Directing at these issues, rational design of novel nanozymes for better applications and deeper understanding of catalytic mechanisms are urgently required. Accordingly,this review focuses on the recent advances on regulating strategies, catalytic mechanisms and relevant biological applications of metal nanozymes with multiple enzymelike performance. Furthermore, future perspectives are outlooked to inspire more attention and efforts on this interesting multi-disciplinary field.

作者： Xuan Li wei yang Center for Perioperative Organ Protection Department of AnesthesiologyDuke University Medical Center

Ischemic stroke is a common and often devastating disease that prima rily affects the elderly.Treatment currently consists predominantly of acute thrombolysis and/or thrombectomy to restore blood flow.This reperfusion therapy,however,is only accessible to a small fraction of stroke patients,and even among these patients,many still suffer lifelong neurologic deficits.Thus,new stroke therapeutics are urgently needed to improve the quality of life for stroke patients.
