Objective:To identify the characteristics of research on scalp acupuncture in the treatment of post-stroke cognitive impairment (PSCI).Methods:This was a bibliometric analysis. We selected relevant studies from both Chinese databases (China National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and WanFang Data Knowledge Service Platform) and English databases (Web of Science, PubMed, and Scopus) from their inception to December 2023. The CiteSpace software was used to perform visual-based analyses of publication trends, collaborative networks among countries and institutions, author collaboration networks, and research hotspots.Results:We included 730 Chinese studies and 112 English-language studies. From 2004 to 2023, the number of publications on scalp acupuncture for PSCI showed an increasing trend. All Chinese studies were published in China, mainly by universities, and the institutional collaboration density was low (0.002 9). For English-language studies, China had the most publications (103), followed by the USA (7) and Germany (3). Chinese universities were the main publishing institutions, and the density of inter-institutional collaboration (0.183 3) was higher than that for Chinese literature. The density of the author collaboration network was 0.005 0 for Chinese studies and 0.023 8 for English-language studies. In Chinese studies, the most frequent keywords with a centrality greater than 0.1 were cognitive impairment (248 times), stroke (240 times), needling (162 times), cerebral infarction (82 times), and electroacupuncture (80 times). In English-language studies, these were stroke (40 times), cognitive impairment (32 times), acupuncture (15 times), dementia (15 times), ischemic stroke (10 times), and mechanism (7 times). For Chinese studies, the top 3 clusters focused on clinical studies of the effects of scalp acupuncture on PSCI. In English-language studies, the top 4 clusters mainly involved research on the effects and assessment methods of scalp acupuncture for PSCI. The timeline map of keywords in Chinese studies showed that before 2015, the high-frequency keywords were stroke, cognitive impairment, needling, electroacupuncture, scalp acupuncture, body acupuncture, rehabilitation, moxibustion, and clinical research. From 2015 onwards, keywords such as rat, apoptosis, inflammatory factors, mechanism research, signaling pathways, mice, and animal experiments appeared. The timeline map of keywords in English-language studies showed that before 2013, there were few accumulated keywords. After 2013, high-frequency keywords included "multi-infarction rat""computer-based cognitive training""apoptosis""electroacupuncture""mild cognitive impairment""randomized controlled trial""scalp acupuncture""post-stroke cognitive impairment""stroke rehabilitation""systematic review" and "hippocampal CA1 region". In Chinese studies, keywords with high burst intensity included cerebral infarction, acupuncture therapy, vascular, baihui (GV-20), review, learning and memory, and scalp acupuncture. In English-language studies, these included "multi-infarction rat""mild cognitive impairment""electroacupuncture""post-stroke cognitive impairment"and"systematic review".Conclusions:Research in this field has grown rapidly in recent years. Chinese studies focus mainly on the clinical effects of scalp acupuncture for PSCI, while English-language studies focus more on related mechanisms. Furthermore, both Chinese and English-language studies show good consistency in the focus of experimental research, which mainly focuses on the mechanisms of electroacupuncture in the treatment of PSCI.

Objective:To construct a Du-moxibustion technique operation scheme suitable for patients with ankylosing spondylitis based on the "multidimensional evidence body" model, so as to provide a reference for clinical Du-moxibustion in the treatment of ankylosing spondylitis.Methods:This study was based on the "multidimensional evidence body" model, integrating evidence such as modern literature, ancient Chinese medicine books, and the experience of famous doctors, and combined with semi-structured interviews of 20 patients to form a first draft of the operation plan from April to June 2023. Twenty traditional Chinese medicine experts from 13 regions participated in the review and revision of the plan through two rounds of consultation and expert consensus meetings from July to August 2023, forming the final draft of the operation scheme.Results:Among 20 experts, there were 3 males and 17 females, aged (42.70 ± 6.57) years old. The effective response rates of the questionnaires in the two rounds of correspondence inquiries were 95%(19/20) and 18/18 respectively, and the expert authority coefficients were 0.80 and 0.81. The coefficients of variation were 0.00-0.19 and 0.00-0.21 respectively, and the Kendall harmony coefficients were 0.179 and 0.344 respectively (both P<0.01). The final scheme included 6 first-level items, including "terms and definitions""assessment""operation point""abnormal situations and handling measures""precautions""effect evaluation" and 27 second-level items and 17 third-level items. Conclusions:The operation scheme of Du-moxibustion technique is scientific, feasible and targeted, which can provide effective guidance for clinical practice and ensure the comprehensiveness and effectiveness of treatment.

OBJECTIVE: To explore the clinical features and management of a child with Chitayat syndrome. METHODS: A child presented at the Fengqing People's Hospital on August 8 2019 was selected as the study subject. Clinical data of the child were retrospectively analyzed. Peripheral blood samples were collected from the child and his father and sister. Whole-exome sequencing (WES) was carried out. Candidate variant was verified by Sanger sequencing. Genome Browser, AlphaFold, and PolyPhen-2 were employed for protein structure simulation and amino acid sequence conservation analysis. Pathogenicity of the variant was rated based on guidelines from the American College of Medical Genetics and Genomics (ACMG). Literature was retrieved from databases including CNKI, Wanfang, and PubMed using the keyword "Chitayat syndrome". The clinical characteristics and prognosis of patients with Chitayat syndrome were reviewed and analyzed. This study was approved by the Ethics Committee the Seventh Affiliated Hospital of Sun Yat-sen University (Ethics No.: KY-2024-086-01). RESULTS: The child was born at full term and had special facial features, skeletal abnormalities, recurrent respiratory tract infections and global developmental delay. WES and Sanger sequencing revealed that he has harbored a heterozygous c.266A>G p.(Tyr89Cys) variant of the ERF gene. Protein structure modeling suggested that the mutant protein has increased spatial distance between the side chain group and DNA, which may reduce its binding affinity to DNA. Amino acid sequence analysis indicated that the p.Tyr89 residue is highly conserved across multiple species. The variant was therefore classified as pathogenic (PM1+PM2_Supporting+PM6+PS1+PP3). The patient was diagnosed with "Chitayat syndrome". Nutritional support and rehabilitation training were recommended, though the child had died of severe pneumonia at 13 months old. Literature retrieval has collected 7 relevant articles, which involved 14 cases of Chitayat syndrome confirmed by genetic testing. Together with our case, all patients had facial dysmorphisms and skeletal deformities. Fourteen patients (93.3%) had respiratory distress. Seven of them (46.7%) had recurrent respiratory infections and 7 (46.7%) were confirmed with respiratory tract malacia. Eight (53.3%) patients had neuropsychological retardation, while 8 (53.3%) had growth delay. The main interventions for Chitayat syndrome include respiratory and nutritional support, and rehabilitation training for developmental delays. CONCLUSION Chitayat syndrome is rarely seen and its clinical manifestations may vary. Airway management and early intervention of developmental delay are important for improving the prognosis.

Objective To investigate the effects of time in range(TIR)and microRNA-2245P(miR-2245P)interac-tions on the susceptibility and severity of diabetic retinopathy(DR)in the target range of glucose.Methods A prospec-tive study was conducted on 259 patients with DR(DR group)and 259 patients with type 2 diabetes mellitus(T2DM group)admitted to the Ophthalmology Department of Yantai Yeda Hospital from April 2022 to June 2024.TIR and miR-2245P were compared between the two groups,and the multivariate Logistic analysis was used to identify the factors associated with DR susceptibility.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of TIR,miR-2245 P,and their combination for DR.The interaction coefficient γ was used to analyze the effect of the interaction between TIR and miR-2245P on DR susceptibility.The Spearman correlation analysis was used to evaluate the correlation of TIR and miR-2245P with DR staging.Results The TIR and miR-2245P levels in the DR group were lower than those in the T2DM group(both P＜0.05).The multivariate logistic regression analysis showed that Logit(P)=0.083-0.470 × TIR-0.584 × miR-2245P,high levels of TIR and miR-2245P were independent protective factors of DR susceptibility(all P＜0.05).The areas under the ROC curve(AUC)of TIR,miR-2245P,and their combination for predicting DR were 0.76,0.79,and 0.91,respectively.The AUC of TIR combined with miR-2245P was greater than that of TIR and miR-2245P(both P＜0.05).The interaction analysis showed that the OR values of DR caused by low levels of TIR and miR-2245P alone were 2.05 and 1.92,respectively.The OR value of the interaction between TIR and miR-2245P was 10.69,greater than the prod-uct of OR values of TIR and miR-2245P alone.It indicates that the effect of the interaction of TIR and miR-2245P on suscep-tibility to DR is a super-multiplication model.The interaction coefficient was γ=3.31＞1,indicating a positive relationship of the interaction between the two factors with DR susceptibility.The Spearman correlation analysis showed that TIR and miR-2245P were negatively correlated with DR staging(both P＜0.001).Conclusion Both TIR and miR-2245P are asso-ciated with DR and its severity,and they have interactive effects on DR susceptibility.Combined detection can improve the predictive value of DR.This study provides a new idea and target for the prevention and treatment of DR.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.

Objective To characterize the changing species distribution and antibiotic resistance profiles of respiratory isolates in hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Methods Commercial automated antimicrobial susceptibility testing systems and disk diffusion method were used to test the susceptibility of respiratory bacterial isolates to antimicrobial agents following the standardized technical protocol established by the CHINET program.Results A total of 589 746 respiratory isolates were collected from 2015 to 2021.Overall,82.6％of the isolates were Gram-negative bacteria and 17.4％were Gram-positive bacteria.The bacterial isolates from outpatients and inpatients accounted for(6.0±0.9)％and(94.0±0.1)％,respectively.The top microorganisms were Klebsiella spp.,Acinetobacter spp.,Pseudomonas aeruginosa,Staphylococcus aureus,Haemophilus spp.,Stenotrophomonas maltophilia,Escherichia coli,and Streptococcus pneumoniae.Each microorganism was isolated from significantly more males than from females(P＜0.05).The overall prevalence of methicillin-resistant S.aureus(MRSA)was 39.9％.The prevalence of penicillin-resistant S.pneumoniae was 1.4％.The prevalence of extended-spectrum β-lactamase(ESBL)-producing E.coli and K.pneumoniae was 67.8％and 41.3％,respectively.The overall prevalence of carbapenem-resistant E.coli,K.pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii was 3.7％,20.8％,9.4％,29.8％,and 73.3％,respectively.The prevalence of β-lactamase was 96.1％in Moraxella catarrhalis and 60.0％in Haemophilus influenzae.The H.influenzae isolates from children(＜18 years)showed significantly higher resistance rates to β-lactam antibiotics than the isolates from adults(P＜0.05).Conclusions Gram-negative bacteria are still predominant in respiratory isolates associated with serious antibiotic resistance.Antimicrobial resistance surveillance should be strengthened in clinical practice to support accurate etiological diagnosis and appropriate antimicrobial therapy based on antimicrobial susceptibility testing results.
