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.

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.

OBJECTIVE To explore the construction of selection system for drug directory of the county-level medical community based on multi-criteria decision analysis,and provide decision-making basis for the selection of drug directory of medical community.METHODS Taking county-level medical community in Chongqing as an example,Delphi method and analytic hierarchy process were employed to construct the selection system for drug directory of the county-level medical community.Selected drugs were quantitatively scored based on the constructed index system,and the drug directory was selected according to the drug's comprehensive score.The implementation effect of the directory was then evaluated through questionnaire surveys one year after the implementation of the directory.RESULTS The expert authority coefficients of the two rounds of consultation were＞0.8,with Kendall's W values of 0.213 and 0.196,respectively(P＜0.001).Finally,the selection system for drug directory of the medical community was determined to include five evaluation dimensions:safety,effectiveness,economy,accessibility,and innovation,along with eight evaluation indicators.In the drug directory selected according to the above method,the proportions of centrally procured drugs,medical insurance drugs,and essential drugs had all increased compared to before the selection;the comprehensive scores of chemical drugs ranged from 50.25 to 96.31 scores,and the proportion of drugs scoring between 70 and 100 scores had increased from 78.06%before selection to 85.82%.Among them,antiparasitic drugs had the highest comprehensive scores,while drugs for the digestive tract and metabolism were the most numerous.The evaluation scores of each indicator and the comprehensive scores of drugs in the drug directory after the selection process increased significantly than before selection(P＜0.05).CONCLUSIONS The selection system for drug directory of the county-level medical community constructed in this study is scientific,objective and operable.This process facilitates the promotion of standardized and unified management of drugs in the medical community.

Objective·To develop a machine learning approach for early identification of metabolic syndromes associated with inflammatory metabolic state changes in breast cancer patients after neoadjuvant therapy,using common laboratory and transthoracic echocardiography indices.Methods·Female patients with primary invasive breast cancer diagnosed at the Department of Breast Surgery,Renji Hospital,Shanghai Jiao Tong University School of Medicine,between September 2020 and September 2022,were included.General patient information,laboratory test results,and transthoracic echocardiography data were collected.After feature extraction,five machine learning algorithms,including random forest(RF),gradient boosting(GB),support vector machine(SVM),K-nearest neighbor(KNN),and decision tree(DT),were applied to construct a prediction model for the changes of the patients' metabolic state after neoadjuvant therapy,and the prediction performances of the five models were compared.Results·A total of 232 cases with valid clinical data were included,comprising 135 cases before neoadjuvant therapy and 97 cases after completing 4 cycles of neoadjuvant therapy.Feature extraction identified five key features:white blood cell count,hemoglobin,high-density lipoprotein(HDL),interleukin-2 receptor,and interleukin-8.In the multi-feature analysis,the area under the receiver operating characferistic curve(AUC)was higher in the combination of white blood cell count,hemoglobin and HDL compared to the combination of interleukin-2 receptor and interleukin-8(RF:0.928 vs 0.772,GB:0.900 vs 0.792,SVM:0.941 vs 0.764,KNN:0.907 vs 0.762,DT:0.799 vs 0.714).The RF,SVM,and GB models showed higher AUC(0.928,0.941,0.900)and accuracy(0.914,0.897,0.776).The SVM model exhibited superior accuracy in the training data compared to the RF and GB models(P=0.394,0.122 and 0.097,respectively).Conclusion·The SVM model can be used to establish a prediction model for identifying breast cancer patients at high risk of developing inflammatory metabolic state-related metabolic syndrome after neoadjuvant therapy by incorporating five common clinical indicators,namely,white blood cell count,hemoglobin,high-density lipoprotein,interleukin-2 receptor,and interleukin-8.SVM modeling may be useful for clinicians to establish individualized screening protocols based on a patient's inflammatory metabolic state.

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 investigate the effect of prostaglandin family(PGs)on non-alcoholic fatty liver disease(NAFLD).Methods HepG2 cells,a human hepatocellular carcinoma cell line,were used as the research subject.The experiment was set up as a control group(Ctrl),fatty change group(FFA),prostaglandin B2(PGB2,10 μg/mL)treatment group,15-keto-prostaglandin E2(15-keto-PGE2,10 μg/mL)treatment group,and 8-iso-prostaglandin F2a(8-iso-PGF2α,10 μg/mL)treatment group.Cell activity was determined by the thiazolyl blue(MTT)assay and lipid deposition was detected by the oil red O staining.The expression levels of inflammatory factors and phosphorylated insulin receptor substrates(p-IRS)were determined by real-time fluorescence quantitative PCR(qRT-PCR)and Western blot,respectively.In addition,15 SPF-grade male C57BL/6J mice were randomly divided into a basic group(CD group,n=5,fed with 10％low-fat forage for 16 weeks),high-fat group(HFD group,n=5,fed with 60％high-fat forage for 16 weeks to model NAFLD),and PGB2 group(n=5,given 20 μg/kg PGB2 daily by tail vein injection for 2 weeks after 16 weeks of 60％high-fat diet feeding).The glucose tolerance level of the mice was detected by the intraperitoneal glucose tolerance test(IPGTT)and the degree of hepatic steatosis was determined by HE staining.Results Oil red O staining showed that PGs had no sig-nificant effect on the lipid deposition of NAFLD,but PGs were able to alleviate the inflammation associated with NAFLD.qRT-PCR re-sults showed that compared with the Ctrl group,the levels of IL-1β in the FFA group increased by 2.274±0.550 times(P=0.002 8),while under the action of 50 μg/mL PGB2,10 μg/mL 15-keto-PGE2 and 10 μg/mL 8-iso-PGF2α,the levels of IL-1β decreased to 0.720±0.036 times(P=0.003 1),0.857±0.225 times(P=0.006 4),and 1.767±0.725 times(P=0.029 7),respectively.Western blot results showed that after PGs treatment,the expression level of p-IRS protein was increased.The body weights of mice in the CD group,HFD group and PGB2 group were(28.560±2.028)g,(49.300±0.667)g,and(40.840±4.043)g,respectively,with statisti-cally significant differences between the groups(P=0.001 7).Moreover,the glucose tolerance results in the PGB2 group were better than those in the HFD group.HE staining results showed compared with the HFD group,the degree of hepatic steatosis in the PGB2 group was reduced.Conclusion PGB2,15-keto-PGE2,and 8-iso-PGF2α in the prostaglandin family can alleviate the occurrence and development of NAFLD by alleviating IL-1β-mediated inflammation,upregulating the expression of p-IRS,promoting the transmission of insulin signaling,and attenuating insulin resistance.
