Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

BACKGROUND:In clinical practice,Cibotium barometz and Epimedium have shown significant efficacy in the treatment of rheumatoid arthritis,but the complex active ingredients contained in the two have an unclear mechanism of action at the molecular level for the treatment of rheumatoid arthritis. OBJECTIVE:Based on network pharmacology and molecular docking technology,to establish a collagen-induced arthritis model and to verify the potential targets and pathways of Cibotium barometz and Epimedium in the treatment of rheumatoid arthritis,providing reliable experimental evidence for the use of clinical formulas with Cibotium barometz and Epimedium as the main components. METHODS:Utilizing traditional Chinese medicine research platforms,traditional Chinese medicine encyclopedias,and databases of traditional Chinese medicine and chemical components from the Shanghai Institute of Organic,effective ingredients were retrieved and identified.3D molecular formulas were obtained from the PubChem platform and target predictions were made using PharmMapper and SwissTargetPrediction.Disease targets for rheumatoid arthritis were obtained from gene databases such as DrugBank,GeneCards,and OMIM.The intersections of targets and Cibotium barometz and Epimedium were plotted using VENNY 2.1 after calibration with the Uniport database.A protein-protein interaction network graph was constructed using the STRING platform.Gene Ontology function analysis and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were performed using the Metascape platform for data visualization.A four-layered network model of traditional Chinese medicine,ingredients,targets,diseases,and pathways was constructed using Cytoscape 3.9.0.The main effective ingredients were docked with core targets using AutoDock-Vina software to explore the best binding targets.A type II collagen+adjuvant-induced arthritis rat model was established,and the effects of Cibotium barometz and Epimedium on relevant pathway targets and inflammatory cell factors were observed after 21 days of intervention. RESULTS AND CONCLUSION:A total of 28 active ingredients from Cibotium barometz and Epimedium were selected,yielding 288 intersection targets for rheumatoid arthritis.The main ingredients included isobavachalcone,cibotium,and epimedium.The main targets included protein kinase 1 for serine/threonine(AKT1),tumor necrosis factor,and vascular endothelial growth factor A.Gene ontology analysis yielded 2 232 biological processes,mainly related to serine protein phosphorylation,positive regulation of serine/threonine protein kinase,and reactive oxygen metabolism.Kyoto Encyclopedia of Genes and Genomes enrichment analysis yielded 202 pathways,mainly involving the PI3K/AKT signaling pathway and epidermal growth factor receptor signaling pathway,which may exert therapeutic effects by regulating synovial cell apoptosis and proliferation and suppressing inflammatory factors.Molecular docking results showed the strongest binding activity and stable structure of Cibotium barometz and Epimedium with AKT1 and estrogen receptor transcription factor 1,which was closely related to apoptosis and proliferation and inflammatory signaling pathways such as PI3K/AKT.Cibotium barometz and Epimedium reduced the expression of interleukin-1β,interleukin-6,and tumor necrosis factor-α in the serum of collagen-induced arthritis rat models.Cibotium barometz and Epimedium reduced the expression of p-PI3K,p-AKT,and p-FOXO1 in the synovium of collagen-induced arthritis rat models.The results indicate that the combination of Cibotium barometz and Epimedium may exert therapeutic effects by inhibiting the proliferation of synovial cells and suppressing the expression of inflammatory factors via the PI3K/AKT/FOXO1 signaling pathway.This may be closely related to the occurrence of inflammation and bone destruction in rheumatoid arthritis,and provides a reference for the rational use and development of new drugs in clinical practice.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period，9 035 strains of Gram-negative bacteria were collected from 51 hospitals，of which 7 895（87.4%）were Enterobacteriaceae and 1 140（12.6%）were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli（ n=4 510，49.9%）， Klebsiella pneumoniae（ n=2 340，25.9%）， Pseudomonas aeruginosa（ n=534，5.9%）， Acinetobacter baumannii complex（ n=405，4.5%）and Enterobacter cloacae（ n=327，3.6%）. The ESBLs-producing rates in Escherichia coli， Klebsiella pneumoniae and Proteus spp. were 47.1%（2 095/4 452），21.0%（427/2 033）and 41.1%（58/141），respectively. The prevalence of carbapenem-resistant Escherichia coli（CREC）and carbapenem-resistant Klebsiella pneumoniae（CRKP）were 1.3%（58/4 510）and 13.1%（307/2 340）；62.1%（36/58）and 9.8%（30/307）of CREC and CRKP were resistant to ceftazidime/avibactam combination，respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii（CRAB）complex was 59.5%（241/405），while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa（CRPA）was 18.4%（98/534）. There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions，with statistically significant differences in the prevalence of CRKP and CRPA（ χ2=20.489 and 20.252， P<0.001）. The prevalence of CREC，CRKP，CRPA，CRAB，ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals（ χ2=11.953，81.183，10.404，5.915，12.415 and 6.459， P<0.01 or <0.05），while the prevalence of CRPA was higher in economically developed regions（per capita GDP ≥ 92 059 Yuan）than that in economically less-developed regions（per capita GDP <92 059 Yuan）（ χ2=6.240， P=0.012）. Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend，and Escherichia coli is ranked in the top，while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different，and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.

The interaction between Mycobacterium tuberculosis and host, as well as the regulation of some signaling pathways in the host, were involved in pathogen latency in macrophages. microRNAs (miRNAs) regulate the gene expression and biological functions, indicating that miRNAs played a regulatory role in bacterial infections. However, whether the host's miRNAs were also involved in the process of Mycobacterium tuberculosis infection had not been thoroughly studied. This study infected macrophages with pathogenic Mycobacterium tuberculosis strain H37Rv and low virulence strain H37Ra to explore the functional miRNAs. By identifying the expression profile of miRNAs in host cells after infection, the expression of 17 miRNAs significantly changed (P < 0.05) in the human macrophage THP-1 infected with highly pathogenic H37Rv strain (Rv), H37Rv inactivated strain (Rv-), and non-pathogenic H37Ra (Ra) strains respectively, indicating that host miRNAs may be involved in the interaction of Mycobacterium tuberculosis and host. Meanwhile, 10 types of miRNAs showed significant differences in cells infected with pathogenic and non-pathogenic Mycobacterium tuberculosis, suggesting that host miRNAs may play an important role in the pathogenicity and intracellular survival of Mycobacterium tuberculosis. Further study had found that miR-449a, miR-502-5p, and miR-708 were downregulated in cells infected with Mycobacterium marinum. Overexpression of these three miRNAs displayed the significant inhibitory effect on the growth of Mycobacterium marinum, indicating that miRNAs played a pivotal role in the interaction between the host and Mycobacterium marinum. This study provided the new insights into the pathogenesis of Mycobacterium tuberculosis and the treatment of tuberculosis.

Aim To observe the behavioral effects of exogenous allopregnanolone(ALLO)and its inhibitor finasteride on the receptive period(R)and non-recep-tive period(NR)of PMDD liver-qi inversion model rats and the expression of GABAARα4,GABAARδ mR-NA and protein effects to explore its pathogenesis.Methods The PMDD liver-qi reverse syndrome rat model was prepared.The rats were divided into the normal group R and NR(control-R,control-NR),model group R and NR(Model-R,Model-NR),nor-mal group R+ALLO and NR+ALLO(Control+A-R,Control+A-NR),and model group R+ALLO and NR+ALLO(Model+A-R,Model+A-NR),model group R+finasteride and NR+finasteride(Model+F-R,Model+F-NR).The elevated cross labyrinth ex-periment and social interaction experiment were used to detect the behaviors of rats;fluorescence quantitative PCR and immunofluorescence were used to detect the expression of GABAARα4 and 8 mRNA and protein in rat amygdala and hippocampus.Results In the be-havioral evaluation,in the NR period,in the elevated cross maze test and in the social interaction test,the rats in the model group had anxiety behavior and de-creased social communication ability(P＜0.05),while the rats in the Model+A group could effectively relieve anxiety symptoms and improve their social com-munication ability(P＜0.05),and the rats in the Model+F group had increased anxiety behavior and social disorder(P＜0.05).In fluorescence quantita-tive PCR and immunofluorescence experiments,the ex-pression of GABAARα4 subunit in the model group was up-regulated in the hippocampus(P＜0.01),and the expression of δ subunit was down-regulated(P＜0.01);the expression of GABAARα4 subunit in the a-mygdala and hippocampus of the Model+A group de-creased(P＜0.01),and the expression of δ subunit increased in the hippocampus(P＜0.01).Conclu-sions The abnormal expression of GABAARα4 and 8 subunits mediated by ALLO improves the anxiety symptoms and social interaction ability of PMDD,which is the pathogenesis of PMDD liver-qi reverse syndrome,and provides basis and support for subse-quent exploration of the pathogenesis of PMDD liver-qi reverse syndrome.

Objective To compare the efficacy of MRI-transrectal ultrasound(TRUS)software fusion-guided biopsy and cognitive fusion-guided biopsy for detecting prostate cancer(PC).Methods Data of 120 patients with suspected PC(127 lesions)who underwent transperineal prostate biopsy with 2-3 times of target biopsy(TB)and 10 times of system biopsy were retrospectively analyzed.According to TB guidance methods,73 cases(78 lesions)received MRI-TRUS software fusion-guided biopsy were classified into group A,and 47 cases(49 lesions)received cognitive fusion-guided biopsy were classified into group B.The positive rate of PC,clinic significant PC(csPC)and PC in different sized lesions by TB were compared between groups,and the positive rate of PC between 2 or 3 times TB was also compared within each group.Results The positive rate of PC and csPC detected by TB was 55.13%(43/78)and 39.74%(31/78)in group A,53.06%(26/49)and 34.69%(17/49)in group B,respectively,no significant difference was found(all P＞0.05).The positive rate of PC in lesions with the maximum diameter≤10 mm detected by TB in group A was higher than that in group B(P＜0.05),but no significant difference of lesions with the maximum diameter＞10 mm and＜15 mm nor≥15 mm was found between groups(all P＞0.05).No significant difference of positive rate of PC was found between 2 and 3 times TB in group A(P＞0.05),while positive rate of PC of 3 times TB was significantly higher than that of 2 times TB in group B(P＜0.05).Conclusion MRI-TRUS software fusion-guided biopsy had positive rate of PC and csPC similar to that of cognitive fusion-guided biopsy,but was helpful for reducing times of TB and increasing detecting rate for lesions with the maximum diameter≤10 mm.

Two new nor-ent-halimane diterpenes and three previously unreported nor-clerodane diterpenes,designated callicain-tides A-E(1-5),were isolated from Callicarpa integerrima.Compounds 1 and 2 feature a distinctive 5/6-membered ring system,while compounds 3-5 are characterized by progressively truncated carbon skeletons,containing 18,17,and 16 carbons,respectively.In addition,four known compounds 6-9 were also identified.Their structures were elucidated using advanced spectroscopic tech-niques,including nuclear magnetic resonance(NMR),high-resolution electrospray ionization mass spectrometry(HR-ESI-MS),ultra-violet(UV),infrared radiation(IR),optical rotatory dispersion(ORD),DP4+analysis and electronic circular dichroism(ECD),sup-ported by quantum chemical calculations.Compounds 1-9 were evaluated for their anti-MRSA activity.Among them,compound 6 demonstrated significant anti-MRSA activity,with a minimum inhibitory concentration(MIC)of 16 μg·mL-1.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To study the clinical characteristics of children with anti-neutrophil cytoplasmic antibody(ANCA)-associated vasculitis(AAV).Methods A retrospective analysis was conducted on the clinical data of 25 children diagnosed with AAV at the Second Xiangya Hospital of Central South University from January 2010 to June 2022.Results Among the AAV children,there were 5 males and 20 females,with a median age of onset of 11.0 years.Involvement of the urinary system was seen in 18 cases(72%);respiratory system involvement in 10 cases(40%);skin involvement in 6 cases(24%);eye,ear,and nose involvement in 5 cases(20%);joint involvement in 4 cases(16%);digestive system involvement in 2 cases(8%).Eleven cases underwent kidney biopsy,with 5 cases(46%)showing focal type,2 cases(18%)showing crescentic type,2 cases(18%)showing mixed type,and 2 cases(18%)showing sclerotic type.Immune complex deposits were present in 5 cases(45%).Seven cases reached chronic kidney disease(CKD)stage Ⅴ,with 2 cases resulting in death.Two cases underwent kidney transplantation.At the end of the follow-up period,2 cases were at CKD stage Ⅱ,and 1 case was at CKD stage Ⅲ.Of the 16 cases of microscopic polyangiitis(MPA)group,13(81%)involved the urinary system.Of the 9 cases of granulomatosis with polyangiitis(GPA),6 cases(66%)had sinusitis.Serum creatinine and uric acid levels were higher in the MPA group than in the GPA group(P<0.05),while red blood cell count and glomerular filtration rate were lower in the MPA group(P<0.05).Conclusions AAV is more common in school-age female children,with MPA being the most common clinical subtype.The onset of AAV in children is mainly characterized by renal involvement,followed by respiratory system involvement.The renal pathology often presents as focal type with possible immune complex deposits.Children with MPA often have renal involvement,while those with GPA commonly have sinusitis.The prognosis of children with AAV is poor,often accompanied by renal insufficiency.

Objective To observe the effect of remifentanil-based fast-track anesthesia on the quality of anesthesia recovery in children with congenital heart disease underwent transcatheter closure.Methods Children with congenital heart disease who underwent transcatheter closure were divided into treatment group and control group according to the anesthesia plan.The anesthesia plan of the control group was as follows:anesthesia induction(intramuscular injection of ketamine at 4 mg·kg-1,intravenous injection of propofol at 2.5 mg·kg-1,fentanyl at 10 μg·kg-1and cisatracurium at 0.1 mg·kg-1)and anesthesia maintenance(fentanyl at0.4μg·kg-1·min-1 and propofol at 8 μg·kg-1·min-1).The anesthesia plan of the treatment group was as follows:anesthesia induction(intramuscular injection of ketamine at 5 mg·kg-,intravenous injection of midazolam at 0.1 mg·kg-1,sufentanil at 1.0 μg·kg-1 and cisatracurium at 0.1 mg·kg-1)and anesthesia maintenance(remifentanil at 0.5 μg·kg-1·min-1 and propofol at 8 μg·kg-1·min-1).Anesthesia recovery,facial expression,leg posture,activity,crying and comfortability(FLACC)of 5 pain scores,Ramsay score,hemodynamics,myocardial injury indexes,and adverse drug reactions were compared between the two groups.Results There were 64 cases in treatment group and 56 cases in control group.The spontaneous respiration recovery time,call time and extubation time of the treatment group were(4.87±1.22),(10.16±2.58)and(12.55±3.19)min,shorter than those in control group,which were(5.49±1.35),(13.34±3.27)and(15.67±3.62)min(all P＜0.05).At 1 h and 2 h after operation,Ramsay scores of treatment group were 2.58±0.35 and 3.69±0.42,were lower than 3.02±0.47 and 4.24±0.39 in control group(all P＜0.05).At 1 h and 2 h after operation,the FLACC scores of the treatment group were 3.03±0.81 and 3.75±0.84,lower than 3.78±0.62 and 4.36±0.51 in control group(all P＜0.05).Mean arterial pressure(MAP)of treatment group at the insertion of laryngeal mask,the insertion of occluder and the end of the operation were(102.45±10.26),(94.18±8.37)and(91.46±10.15)mmHg,lower than those in control group,which were(107.84±10.11),(100.57±9.84)and(97.33±8.53)mmHg(all P＜0.05).On day 1 and day 3 after operation,serum creatine kinase isoenzyme(CK-MB)levels in the treatment group were(10.03±2.58)and(8.65±2.16)U·L-1,lower than those in control group,which were(12.44±3.07)and(10.16±2.35)U·L-1(all P＜0.05).On day 1 and day 3 after operation,serum cardiac troponin Ⅰ(cTn Ⅰ)levels in treatment group[(0.07±0.02)and(0.04±0.01)μg·L-1]were lower than those in control group[(0.09±0.03)and(0.06±0.02)μg·L-1](all P＜0.05).The incidence of adverse anesthesia reactions in treatment group was 6.25％(4 cases/64 cases),lower than 17.86％(10 cases/56 cases)in control group(P＜0.05).Conclusion Remifentanil-based fast-track anesthesia can improve the quality of anesthesia recovery in children with congenital heart disease undergoing transcatheter closure,with good sedative and analgesic effects,stable hemodynamics during operation,and low incidence of adverse drug reactions.
