Objective To describe and evaluate the clinical studies of postoperative pain sensitization caused by sleep deprivation through the evidence map system,understand the distribution of evidence in this field,and provide reference for subsequent evidence research.Methods A computer-based search of PubMed,EMBASE,Cochrane library,Web of Science,CNKI,Wanfang Data,VIP and Chinese Biomedical Literature Database from inception to August 2023 was conducted to obtain intervent ion studies,observational studies and systematic reviews/Meta-analysis of postoperative pain sensitization caused by sleep deprivation.The research characteristics and methodological quality were analyzed and evaluated.The Cochrane Handbook for Systematic Reviews,the Newcastle-Ottawa Scale(NOS)and the AMSTAR-2 scale were used to evaluate the quality of the included studies,and the evidence was comprehensively analyzed and displayed by means of bubble chart,table and text.Results A total of 35 observational studies(31 cohort studies and 4 case-control studies),15 randomized controlled trials and 4 systematic reviews/Meta-analyses were included.The number of publications increased rapidly after 2018 and peaked in 2022,and clinical studies in this field mainly fo-cused on cohort studies,with fewer randomized controlled trials and systematic reviews/Meta-analysis studies.The results of the evidence map showed that in terms of quality,22 studies were'high quality',24 studies were'medium quality',and 8 studies were'low quality'.Thirty studies showed that sleep deprivation could induce postoperative pain sensitization.Only 2 studies suggested that sleep disorders were not significantly asso-ciated with postoperative pain sensitization,and ten studies were uncertain whether sleep deprivation could in-duce postoperative pain sensitization.Conclusions Overall evidence shows that sleep deprivation can induce postoperative pain sensitization,but the evaluation dimensions are limited and the methodological quality of the included literature needs to be improved.More high-quality,large-sample and standardized clinical studies should be carried out in the future to provide better scientific basis for clinical work.

Objective To investigate the regulation of synaptic plasticity by cannabinoid receptor 1(CB1R)and its effects on autism spectrum disorder(ASD)-like behavior.Methods CB1R-knockout(KO)mice and valproic acid(VPA)-induced ASD model mice(VPA mice)were used as study subjects.Behavioral experiments were used to assess the effects of CB1R on ASD-like behavior in mice,neuronal structural integrity and dendritic density were detected by microtubule-associated protein 2(MAP2)staining experiments,and the expression of synapse-associated proteins was detected by Western blot,to assess the effects of CB1R on synaptic plasticity.Results Behavioral result showed that VPA mice demonstrated significant ASD-like behavior,while CB1R-/-mice spent a significantly smaller proportion of residence time in the central region of the open field(P＜0.0001),showed significant increases in the number of marbles buried and self-grooming time(P＜0.01),significantly less time spent socializing with unfamiliar mice 2 and exploring unfamiliar objects(P＜0.001),and significantly more time exploring old objects(P＜0.05).The relative dwelling time was significantly reduced in CB1R+/-mice(P＜0.001),and the number of marbles buried and self-grooming time were significantly increased(P＜0.05).Synaptic plasticity assays revealed significant synaptic plasticity impairment in VPA mice.Hippocampal MAP2-positive neuron densities were significantly reduced in CB1R-/-and CB1R+/-mice,and expression levels of synapsin-1 were significantly increased(P＜0.05).Conclusions CB1R KO leads to ASD-like behavior such as anxiety and repetitive stereotyped behavior,social and cognitive impairments,as well as neuronal damage,dendritic dysplasia and disrupted synaptic protein expression in mice,suggesting that CB1R is involved in regulating synaptic plasticity as a pathological mechanism for the development of ASD-like behavior.

Objective:To investigate the role of serotonergic (5-HT) neurons activation in the dorsal raphe nucleus (DRN) in heat-induced seizures and its influence on breathing patterns in Scn1a + /- mice. Methods:24-day-old male Scn1a + /- mice were used for experiments, and sudden unexpected death in epilepsy(SUDEP) model was established through heat induction for 5 consecutive days. (1) Fluoxetine intervention experiment: 20 male mice were randomly divided into model group( n=10) and fluoxetine group ( n=10) according the weight-matched method. The fluoxetine group received intraperitoneal injection of fluoxetine (10 mg/kg) 45 min before heat induction each day for 5 consecutive days, while the model group received equal volume of 0.9% NaCl solution. (2) Chemogenetic activation experiment: 20 male mice were randomly divided into vector control group( n=10) and chemogenetic activation group ( n=10) according the weight-matched method. Empty vector or rAAV-TPH2-hM3d(Gq)-EGFP-WPREs was stereotaxically injected into DRN 14 d prior to seizure induction, and deschloroclozapine (5 mg/kg) was intraperitoneally injected 30 min before heat induction. Seizure characteristics and survival were assessed through video monitoring, and respiratory parameters were monitored. Immunofluorescence was used to detect colocalization of tryptophan hydroxylase 2(TPH2) and c-Fos in DRN. Statistical analysis was performed using SPSS 24.0 and GraphPad Prism 9.0. The independent sample t-test or Mann-Whitney test was used for inter-group comparison. Results:(1) In the fluoxetine intervention experiment: the survival rates between the model group and fluoxetine group showed no statistically significant difference ( χ2=2.23, P>0.05). As for the frequency of grade Ⅳ seizures, the model group (1.50(1.25, 2.35)min) demonstrated higher frequency than the fluoxetine group (0.43(0.20, 0.67)min) ( t=-3.40, P<0.05).With respect to respiratory parameters, the model group demonstrated shorter expiratory time ((0.10±0.02) s) and inspiratory time ((0.15±0.02) s) compared to the fluoxetine group ((0.16±0.05) s, (0.19±0.04) s) ( t=-3.47, -3.73, both P<0.01). The respiratory rate in the model group ((269.96±44.84) times/min) was significantly higher compared to the fluoxetine group ((195.04±52.37) times/min) ( t=3.44, P<0.01). The tidal volume in the model group ((0.10±0.02) mL) was significantly lower than the fluoxetine group ((0.13±0.04) mL) ( t=-2.19, P<0.05).The number of TPH2+ /c-Fos+ co-expressing cells in the model group (11.00±4.00) was lower than that in the fluoxetine group (33.00±8.39)( t=-4.16, P<0.05). (2) In the chemogenetic activation experiment: compared to the vehicle group, the chemogenetic activation group demonstrated significantly enhanced survival rates ( χ2=5.83, P<0.05). As for the frequency of grade Ⅴ seizures, the vehicle group (2.11(1.62, 3.44) times/min) showed higher frequency compared to the chemogenetic activation group (0.81(0.00, 1.62) times/min) ( t=18.00, P<0.05). In terms of respiratory parameters, the vehicle group showed shorter expiratory time ((0.10±0.01) s) and inspiratory time ((0.14±0.01) s) compared to the chemogenetic activation group ((0.12±0.01) s, (0.15±0.01) s) ( t=-2.78, -2.50, both P<0.05). The respiratory rate in the vehicle group ((208.37±9.73) times/min) was significantly higher than the chemogenetic activation group ((191.85±8.83) times/min) ( t=3.98, P<0.01). The tidal volume in the vehicle group ((0.09±0.01) mL) was significantly lower than the chemogenetic activation group ((0.12±0.02) mL) ( t=-4.77, P<0.001).The number of TPH2+ /c-Fos+ co-expressing cells in the vehicle group (9.00±3.46) was lower than that in the chemogenetic activation group (43.00±11.02)( t=-5.20, P<0.01). Conclusion:Specific activation of serotonergic neurons in the DRN can ameliorate heat-induced epileptic symptoms, improve respiratory function, and prolong survival time in Scn1a + /- mice.

Objective To investigate the main pharmacological basis and mechanism of action of Guhuaisi Kangfu Pill(GHSKF)in the treatment of steroid-induced osteonecrosis of the femoral head(SONFH).Methods The active constituents and targets of GHSKF were screened by using Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)and other databases.The speculative targets of SONFH were screened out based on GeneCards and Online Mendelian Inheritance in Man(OMIM)databases.The gene modules and hub genes of SONFH were identified using a weighted gene co-expression network analysis(WGCNA).The intersection of the two targets and the result of WGCNA was taken to obtain the potential targets of GHSKF for the treatment of SONFH.The key active constituents were screened with the"active constituent-target"network,which was constructed by the Cytoscape software.Then,the STRING database was used to construct the protein interaction network to screen the key targets.The Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis of key targets was performed,and the relationship between key active constituent,key targets and key signaling pathways was explored.Finally,the molecular docking between key active constituents and key targets was verified.In addition,the SONFH rat model was used for experimental verification.Results A total of 146 compounds and the corresponding 346 targets were identified based on the TCMSP database.A total of 4 187 targets of SONFH were obtained based on GeneCards and OMIM databases.In addition,twelve gene modules and 2 556 hub genes of SONFH were screened out based on WGCNA.Quercetin,luteolin and kaempferol were key active ingredients for the treatment of SONFH.Various signaling pathways such as PI3K/AKT were involved.Molecular docking showed the key active ingredients had good binding activity with the key targets.The results of animal experiments demonstrated that GHSKF could improve bone biological alterations by up-regulating AKT1,PI3K,RUNX2,and down-regulating the expression of Caspase-3 and IL-6(P＜0.01),which verified some results of the network pharmacology prediction.Conclusion We analyzed the potential mechanism of action of GHSKF for the treatment of SONFH using network pharmacology and animal experiments,which may provide a reference for further research on its pharmacological basis and targets.

Objective To understand the proficiency level and sources of Traditional Chinese Medicine(TCM)health education among hemodialysis patients,in order to provide the basis for promoting the application of TCM nursing in hemodialysis patients.Methods Utilizing a convenience sampling approach,we conducted a survey from April to May 2023 involving hemodialysis patients from 7 tertiary TCM hospitals across Beijing,Hebei Province,Sichuan Province,and other regions.Custom-made questionnaires were utilized,gathering general information,respons-es conceming the level of mastery on TCM health education,and their primary sources of such knowledge.Results A total of 413 questionnaires were disseminated,and 392 proved valid,yielding a valid response rate of 94.92％.The score of patient's knowledge on TCM health education averaged(8.25±3.73),and an average score rate of 48.53％was obtained.In the patients undergoing hemodialysis,a relatively larger number of people possess knowl-edge of TCM health knowledge about relieving symptoms(50.8％～55.9％)and traditional Chinese daily life routines(56.4％～90.1％).However,fewer people are aware of how to use the five-tone therapy method for emotional inter-vention(40.8％)and principle of taking restorative Traditional Chinese Medicine(24.5％～36.7％),the dietary prin-ciples of"nurturing yang in spring and summer,and nurturing yin in autumn and winter"(14.3％),and theories of TCM kidney functions(9.9％).Approximately 23.0％of the patients sourced their TCM health education knowledge from new media platforms.Compared with new media method alone,patients who utilized only traditional education-al platforms(P=0.020),and those who combined both new media and traditional methods(P=0.018)demonstrated higher proficiency in TCM health education.Conclusion Hemodialysis caregivers are urged to develop a TCM health education framework that emphasizes emotional well-being and traditional wellness concepts,thereby fostering patient-centric TCM health ideologies.Hemodialysis education personnel are encouraged to leverage new media whilst ensuring education quality and effective outcomes.

Objective: To conduct a systematic review and meta-analysis of studies evaluating the oncological and fertility outcomes of early-stage endometrial cancer (EC) treated with the levonorgestrel-releasing intrauterine system (LIUS)-based regimens. Methods: The Meta-analyses Of Observational Studies in Epidemiology statement for meta-analyses was followed. Searches were conducted on MEDLINE, Embase, PubMed, Preprints, and the Cochrane Central Register of Controlled Trials from January 1990 to August 4, 2022. The Joanna Briggs Institute Critical Appraisal Checklist was used for quality assessment. The primary endpoint was the complete response (CR) rate and the secondary endpoints were relapse, pregnancy, and live birth rate. Results: A total of 25 studies (821 women) were included. The CR rate of LIUS-based regimens was 63.4% (95% confidence interval [CI]=52.3%–73.2%), with 29.6% (95% CI=23.3%–36.8%) of cases experiencing recurrence during follow-up. In sensitivity analyses, patients younger than 45 years of age with a body mass index <30 kg/m2 who were treated with LIUS-based regimens achieved a high CR rate of 84.6% (95% CI=80.3%–88.1%) over a median follow-up of more than 24 months. Overall pregnancy and live birth rates were 37.9% (95% CI=24.1%–53.9%) and 39.3% (95% CI=24.0%–57.0%), respectively. No statistical differences were apparent in CR or relapse rates among the LIUS+GnRH agonist, LIUS+oral progesterone, or hysteroscopic resection followed by LIUS subgroups. Conclusion LIUS-based therapies are viable for the conservative management of early-stage endometrioid EC on CR and fertility outcome.
