OBJECTIVE To standardize the strategies for prevention and control of Chikungunya(CHIK)in healthcare in-stitutions so as to reduce the risk of transmission in the institutions.METHODS A working group comprising the ex-perts in hospital infection control,infectious diseases,and microbiology systematically reviewed domestic and international evidence and current guidelines,integrated China's vector ecology and healthcare realities,conducted two rounds of Delphi to achieve expert consensus,and graded the evidence and recommendation strength using the Oxford Centre for Evidence Based Medicine system.RESULTS The consensus issues 18 actionable recommendations on triage,patient mosquito-proof isolation,integrated vector control,protection of susceptible populations,environmental cleaning and disinfection,specimen management,medical textile handling,and outbreak emergency response,with each statement assigned an evi-dence level and recommendation strength.CONCLUSION This consensus is for the first time in China to provide evidence-graded strategies for control of CHIK in healthcare institutions,offering work flow-oriented,implementable guidance for clinicians,laboratorians,and infection-control personnel under different risk scenarios and enhancing the comprehensive coping capacity of the healthcare institutions.

Objective To explore the therapeutic effect and mechanism of electroacupuncture on depressive model mice based on the phosphatase and tensin homolog-induced kinase 1(PINK1)/Parkin pathway.Methods Specific pathogen-free grade male C57BL/6J mice were used.For experiment 1,60 mice were randomly divided into blank,model,sham electroacupuncture,and electroacupuncture groups using the random number table method,with 15 rats per group.For experiment 2,30 mice were randomly divided into normal,cyclosporine A(CsA),and electroacupuncture+CsA groups using the same method,with 10 rats per group.The chronic restraint stress(CRS)was used to establish a depression model.After successful modeling,CRS was continued to maintain model stability.After modeling,1 h before daily CRS stimulation,the electroacupuncture and electroacupuncture+CsA groups received electroacupuncture interventions at the"Baihui"(GV20)and"Zusanli"(ST36)acupoints,using continuous wave stimulation at a frequency of 2 Hz and an intensity of 1 mA for 20 min,once daily for 7 consecutive days.Mice in the sham electroacupuncture group received superficial needling at non-meridian,non-acupoint locations under the axilla 1 h before CRS,with the electroacupuncture device connected but not powered on once a day for 7 consecutive days.Mice in the CsA and electroacupuncture+CsA groups received an intraperitoneal injection of CsA solution(0.2 mg/g)30 min before electroacupuncture intervention,once daily for 7 consecutive days.In experiment 1,depressive-like behavior was assessed using the open field,tail suspension,and sucrose preference tests.The spontaneous excitatory postsynaptic currents(sEPSC)and spontaneous inhibitory postsynaptic currents(sIPSC)parameters of hippocampal neurons were evaluated using brain slice patch clamp techniques.Western blotting was conducted to measure the expression levels of mitochondrial autophagy-related proteins PINK 1,phosphorylated PINK1(p-PINK1),Parkin,microtubule-associated protein 1A/1B-light chain 3-Ⅱ/Ⅰ(LC3-Ⅱ/Ⅰ),ubiquitin-binding protein(p62),and mitochondrial markers,including translocase of outer mitochondrial membrane 20(TOMM20),heat shock protein 60(HSP 60),and cytochrome c oxidase Ⅳ(COX Ⅳ).Immunofluorescence was used to detect PINK1 protein expression in the CA3 region of the hippocampus.Transmission electron microscopy was used to examine the ultrastructure of mitochondria in hippocampal neurons.On the basis of experiment 1,experiment 2 evaluated depressive-like behavior in mice using sucrose preference,open field,and tail suspension tests;Western blotting was used to detect the expressions of PINK1,p-PINK1,Parkin,LC3-Ⅱ/Ⅰ,p62,TOMM20,HSP 60,and COX Ⅳ proteins of hippocampus in mice.The mitochondrial ultrastructure was observed in hippocampal neurons using transmission electron microscopy.Results In experiment 1,compared with the blank group,the model and sham electroacupuncture groups exhibited a decrease in sucrose consumption rate,a decrease in the time spent in the center area,a reduced proportion of distance moved in the center area,and an increase in immobility time of tail suspension(P＜0.05).The sEPSC and sIPSC in hippocampal neurons decreased in both amplitude and frequency(P＜0.05).p-PINK1,Parkin,LC3-Ⅱ/Ⅰ,TOMM20,HSP 60,and COXⅣ expression levels in the hippocampus were reduced,whereas the p62 expression level was increased(P＜0.05).The average fluorescence intensity of PINK1 in the CA3 region of the hippocampus decreased(P＜0.05).The number of healthy mitochondria in hippocampal neurons was reduced,with numerous damaged mitochondrial structures observed.Compared to the model and sham electroacupuncture groups,the electroacupuncture group showed an increased in the time spent in the center area,a higher proportion of distance moved in the center area,and an elevated sucrose consumption rate.In contrast,the immobility time in the tail suspension test decreased(P＜0.05),whereas the amplitude and frequency of sEPSC and sIPSC in hippocampal neurons increased(P＜0.05).p-PINK1,Parkin,LC3-Ⅱ/Ⅰ,TOMM20,HSP 60,and COXⅣ expression levels in the hippocampus increased,whereas the p62 expression level decreased(P＜0.05).The average fluorescence intensity of PINK1 in the CA3 region of the hippocampus increased(P＜0.05).Additionally,mitochondrial damage in hippocampal neurons was alleviated,and a notable presence of autophagosomes mitophagy lysosomes was observed.In experiment 2,compared with the normal group,the mice in the CsA and electroacupuncture+CsA groups showed a decrease in the time spent in the center area and the proportion of distance moved in the center area,a decrease in sucrose consumption rate,and an increase in the immobility time in the tail suspension test(P＜0.05).p-PINK1,Parkin,LC3-Ⅱ/Ⅰ,TOMM20,HSP 60,and COX Ⅳ expression levels in the hippocampus decreased,whereas p62 expression increased(P＜0.05).Many damaged mitochondria were observed in hippocampal neurons.Conclusion Electroacupuncture may exert its antidepressant effects by promoting PINK1/Parkin pathway-mediated mitophagy to eliminate damaged mitochondria,thereby restoring the function of hippocampal neurons in depressive model mice.

Sleep disorders have become a global public health problem,and traditional diagnosis and treatment are limited by low accessibility and high subjectivity.In recent years,artificial intelligence(AI)technology has brought innovative opportunities for sleep health monitoring,diagnosis and intervention.In this paper,we systematically review the research progress of AI in the field of sleep:home monitoring based on wearable devices and contactless sensing achieves continuous and senseless data collection;deep learning models(such as convolutional neural network,recurrent neural network,and their hybrid architectures)significantly improve the automation and accuracy of sleep staging;and in clinical applications,AI assists in the diagnosis of obstructive sleep apnea,promotes the development of OSA diagnosis and treatment technologies as well as related research,and supports to form personalised intervention strategies.Despite its bright prospects,the application of AI in sleep health still faces numerous challenges,such as data privacy,algorithmic bias,insufficient model interpretability and lack of clinical validation.It should be made clear that AI is positioned to enhance,rather than replace clinical professional judgment.In the future,multimodal fusion,generative AI and big language models for health will further contribute to the intelligence and personalisation of sleep management.This study aims to provide reference for researchers and clinicians to promote the deep integration of AI and sleep medicine.

It is found that acupuncture can significantly improve the clinical symptoms of rheumatoid arthritis (RA) such as pain and joint stiffness, and improve rheumatoid factor, high-sensitivity CRP, ESR and other clinical indicators. It can inhibit the proliferation of synovial cells, the apoptosis of chondrocytes, and regulate polarization balabce of mononuclear macrophages, T cells, as well as inhibit the inflammatory function of multiple immune cells, in order to improve inflammation state of RA joints. In clinical treatment of RA, bladder meridian, stomach meridian, spleen meridian , and Governor Vessel are mostly selected. Acupoints with the efficacy of warming meridian, dispelling coldness and dredging collaterals were commonly selected such as Zusanli (ST36), Yanglinquan (GB34), Dazhui (GV14), Quchi (LI11). Several researches have proved that combined therapy of acupuncture and medicine is worthy promotion in clinic.

Objective:To explore the efficacy and safety of combining minimally invasive hematoma puncture with urokinase irrigation and continuous drip drainage in patients with spontaneous intracerebral hemorrhage.Methods:A total of 22 patients with spontaneous intracerebral hemorrhage admitted to Department of Functional Neurosurgery, Zhujiang Hospital of Southern Medical University and Department of Neurosurgery of Yuebei People's Hospital from May 2023 to January 2024 were chosen. Using precise localization, a minimally invasive haematoma puncture was used to insert a balloon drainage catheter into the hematoma cord; urokinase irrigation was administered during the procedure, followed by continuous drip drainage postoperatively. A retrospective analysis was performed; their clinical data before and after the procedure were collected; and Glasgow Coma Scale (GCS) score, hematoma residual volume, hematoma evacuation rate and complications were analyzed.Results:In these 22 patients, the residual hematoma volume after intraoperative suction was (20.89±10.74) mL, with a residual rate of (51.86±14.88)%. After the 1 st urokinase injection for continuous drainage, the residual hematoma volume in the 22 patients was (12.72±7.92) mL, with a hematoma evacuation rate of (35.01±30.41)%. After the 2 nd injection, the residual hematoma volume in the 13 patients was (9.48±6.12) mL, with a hematoma evacuation rate of (42.03±20.89)%. After the 3 rd injection, the residual hematoma volume in the 7 patients was (5.84±2.84) mL, with a hematoma evacuation rate of (49.32±11.09)%. After the 4 th injection, the residual hematoma volume in the 3 patients was (3.67±3.79) mL, with a hematoma evacuation rate of (54.44±32.03)%. After the 5 th injection, the residual hematoma volume in the left 1 patient was 5 mL, with a hematoma evacuation rate of 37.50%. Before tube removal, the residual hematoma volume in these 22 patients was (6.73±5.01) mL, with a hematoma evacuation rate of (81.48±13.56)%. During hospitalization, 1 patient experienced postoperative hemorrhage and ultimately died of cardiac arrest; 1 patient developed pulmonary infection after surgery and cured with antibiotics. These patients had GCS scores of 12.23±3.16 at discharge, which was significantly increased than those at admission (9.45±3.19, P<0.05). Conclusion:Minimally invasive hematoma puncture combined with urokinase irrigation and continuous drip drainage is a safe and effective new treatment in spontaneous cerebral hemorrhage.
