Through collecting the existing clinical evidences on acupuncture and moxibustion for urticaria, the distribution of evidence in this field was mapped. A systematic search of Chinese and English literature was conducted in CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library for treatment of urticaria with acupuncture and moxibustion, published up to December 31, 2023 since inception of each database. The research status in this field was summarized using an evidence mapping approach, and methodological quality was assessed. A total of 323 randomized controlled trials (RCTs) and 22 systematic reviews were included. The number of studies on acupuncture and moxibustion for urticaria has been increasing, with a significant rise in recent years. In most RCTs, the study scale was small, and the subjects focused on chronic spontaneous urticaria in adolescents and middle-aged adults, aged 14 to 60 years. Regarding the intervention measures, the single therapy of acupuncture and moxibustion was predominant such as acupoint injection, acupoint embedding thread, and filiform needling. In acupuncture with filiform needles, the commonly used acupoints were Quchi (LI11), Xuehai (SP10), Sanyinjiao (SP6), Zusanli (ST36) and Hegu (LI4). The main outcome measures referred to effectiveness rate, score of disease severity, recurrence rate, laboratory indexes, and score of quality of life; and the short-term effect was evaluated specifically. The overall methodological quality of the included studies was relatively low. It is suggested that the future research should focus on large-scale, multi-center, high-quality clinical trials, optimize the protocols for acupuncture and moxibustion intervention, standardize the outcomes, and draw the attention to the evaluation of long-term efficacy, so as to provide clinical evidences of high certainty for urticaria treated with acupuncture and moxibustion.

Objective To investigate the distribution and antimicrobial resistance profiles of common pathogens isolated from cerebrospinal fluid(CSF)in CHINET program from 2015 to 2021.Methods The bacterial strains isolated from CSF were identified in accordance with clinical microbiology practice standards.Antimicrobial susceptibility test was conducted using Kirby-Bauer method and automated systems per the unified CHINET protocol.Results A total of 14 014 bacterial strains were isolated from CSF samples from 2015 to 2021,including the strains isolated from inpatients(95.3％)and from outpatient and emergency care patients(4.7％).Overall,19.6％of the isolates were from children and 80.4％were from adults.Gram-positive and Gram-negative bacteria accounted for 68.0％and 32.0％,respectively.Coagulase negative Staphylococcus accounted for 73.0％of the total Gram-positive bacterial isolates.The prevalence of MRSA was 38.2％in children and 45.6％in adults.The prevalence of MRCNS was 67.6％in adults and 69.5％in children.A small number of vancomycin-resistant Enterococcus faecium(2.2％)and linezolid-resistant Enterococcus faecalis(3.1％)were isolated from adult patients.The resistance rates of Escherichia coli and Klebsiella pneumoniae to ceftriaxone were 52.2％and 76.4％in children,70.5％and 63.5％in adults.The prevalence of carbapenem-resistant E.coli and K.pneumoniae(CRKP)was 1.3％and 47.7％in children,6.4％and 47.9％in adults.The prevalence of carbapenem-resistant Acinetobacter baumannii(CRAB)and Pseudomonas aeruginosa(CRPA)was 74.0％and 37.1％in children,81.7％and 39.9％in adults.Conclusions The data derived from antimicrobial resistance surveillance are crucial for clinicians to make evidence-based decisions regarding antibiotic therapy.Attention should be paid to the Gram-negative bacteria,especially CRKP and CRAB in central nervous system(CNS)infections.Ongoing antimicrobial resistance surveillance is helpful for optimizing antibiotic use in CNS infections.

Objective To investigate the antimicrobial resistance of clinical isolates from elderly patients(≥65 years)in major medical institutions across China.Methods Bacterial strains were isolated from elderly patients in 52 hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program during the period from 2015 to 2021.Antimicrobial susceptibility test was carried out by disk diffusion method and automated systems according to the same CHINET protocol.The data were interpreted in accordance with the breakpoints recommended by the Clinical and Laboratory Standards Institute(CLSI)in 2021.Results A total of 514 715 nonduplicate clinical isolates were collected from elderly patients in 52 hospitals from January 1,2015 to December 31,2021.The number of isolates accounted for 34.3％of the total number of clinical isolates from all patients.Overall,21.8％of the 514 715 strains were gram-positive bacteria,and 78.2％were gram-negative bacteria.Majority(90.9％)of the strains were isolated from inpatients.About 42.9％of the strains were isolated from respiratory specimens,and 22.9％were isolated from urine.More than half(60.7％)of the strains were isolated from male patients,and 39.3％isolated from females.About 51.1％of the strains were isolated from patients aged 65-＜75 years.The prevalence of methicillin-resistant strains(MRSA)was 38.8％in 32 190 strains of Staphylococcus aureus.No vancomycin-or linezolid-resistant strains were found.The resistance rate of E.faecalis to most antibiotics was significantly lower than that of Enterococcus faecium,but a few vancomycin-resistant strains(0.2％,1.5％)and linezolid-resistant strains(3.4％,0.3％)were found in E.faecalis and E.faecium.The prevalence of penicillin-susceptible S.pneumoniae(PSSP),penicillin-intermediate S.pneumoniae(PISP),and penicillin-resistant S.pneumoniae(PRSP)was 94.3％,4.0％,and 1.7％in nonmeningitis S.pneumoniae isolates.The resistance rates of Klebsiella spp.(Klebsiella pneumoniae 93.2％)to imipenem and meropenem were 20.9％and 22.3％,respectively.Other Enterobacterales species were highly sensitive to carbapenem antibiotics.Only 1.7％-7.8％of other Enterobacterales strains were resistant to carbapenems.The resistance rates of Acinetobacter spp.(Acinetobacter baumannii 90.6％)to imipenem and meropenem were 68.4％and 70.6％respectively,while 28.5％and 24.3％of P.aeruginosa strains were resistant to imipenem and meropenem,respectively.Conclusions The number of clinical isolates from elderly patients is increasing year by year,especially in the 65-＜75 age group.Respiratory tract isolates were more prevalent in male elderly patients,and urinary tract isolates were more prevalent in female elderly patients.Klebsiella isolates were increasingly resistant to multiple antimicrobial agents,especially carbapenems.Antimicrobial resistance surveillance is helpful for accurate empirical antimicrobial therapy in elderly patients.

Purpose To investigate the clinicopathological features and molecular genetic alteration of Epstein-Barr virus-positive diffuse large B-cell lymphoma(EBV+DLBCL)in pediatric patients.Methods Clinical data were collected for 3 pediatric patients diagnosed with EBV+DLBCL.Immunohistochemistry(EnVision two-step method)was used to evaluate expression of CD20,CD79α,CD3,CD5,CD30,EBNA2,Fascin,and GATA3.In situ hybridization detected EBER1/2 expression.B-cell receptor(BCR)and T-cell receptor(TCR)gene rearrangements were performed to evaluate the clonal rearrangement of tumor lymphocytes.Results Among the 3 pediatric patients(ages 13-18),there were 2 males and 1 female.All patients presented with painless lymphadenopathy without bone marrow involve-ment.One female patient exhibited B symptoms(fever,night sweats,and weight loss),whereas both male patients were asymptomatic.According to the Lugano classification,2 cases were stage Ⅲand one was stage Ⅳ.Histopathologi-cally,2 cases exhibited a polymorphic morphology resembling T-cell/histiocyte-rich large B-cell lymphoma,and one case demonstrated monomorphic morphology typical of conventional DLBCL.Immunophenotypically,all cases strongly expressed various B-cell transcription factors;CD30 expression varied in intensity;EBNA2,Fascin and GATA3 were uniformly negative.In situ hybridization indicated EBER1/2 positive expression in large tumor cells and scattered back-ground small lymphocytes.Clonal Ig gene rearrangement peaks were detected in all 3 cases.Each patient received standard DLBCL chemotherapy,and follow-up PET-CT scans indicated complete remission in all.Conclusion Pediat-ric EBV+DLBCL is rare,and diagnosing the polymorphic subtype poses particular challenges.In China,many patholo-gists consider detection of clonal Ig gene rearrangement as the diagnostic"gold standard".Even when clinical course and imaging data strongly support EBV+DLBCL,final diagnosis can remain controversial.Further accumulation of ca-ses and long-term follow-up are needed to elucidate optimal diagnostic criteria,treatment responses,and prognostic fac-tors.

Objective To explore the effects of Yin Yang 1(YY1)on the proliferation and migration of bladder cancer cells and investigate the underlying mechanisms,so as to provide reference for the prevention and treatment of this disease.Methods The expression patterns of YY1 in common genitourinary tumors and their associations with the prognosis were analyzed using data from The Cancer Genome Atlas(TCGA)and the Gene Expression Omnibus(GEO).The efficiency of YY1 knockdown and overexpression in bladder cancer cell lines(T24 and UM-UC-3)was confirmed with quantitative reverse transcription PCR(qRT-PCR)and Western blotting.Cell proliferation and migration were assessed using methylthiazolyldiphenyl-tetrazolium bromide(MTT)and Transwell assays.RNA sequencing followed by bioinformatics analyses,including Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG),and Gene Set Enrichment Analysis(GSEA),was conducted to predict potential mechanisms.The qRT-PCR and rescue experiments were performed to validate whether YY1 exerted its effects via the E2F1 signaling pathway.Results YY1 was significantly overexpressed in bladder cancer compared to other genitourinary tumors and was associated with higher tumor grade and poorer prognosis(P＜0.05).Functional assays demonstrated that YY1 promoted the proliferation and migration of bladder cancer cells.Transcriptome analyses revealed that YY1 might regulate these processes through the E2F signaling pathway.Moreover,overexpression of E2F1 partially reversed the inhibitory effects of YY1 knockdown on bladder cancer cell proliferation and migration.Conclusion YY1 is upregulated in bladder cancer and is closely associated with tumor grade and unfavorable prognosis.It may facilitate tumor cell proliferation and migration by modulating the E 2F1 signaling pathway.

Objective To explore the effects of alpha-mangostin(α-MG)on the in vitro osteoarthritis(OA)in rat chondrocytes induced by lipopolysaccharide(LPS)and the M1 polarization of macrophages.Methods An in vitro OA model of rat chondrocytes was induced by LPS.Both rat chondrocytes and macrophages were divided into the control group(normal culture),LPS group(stimulated with 1 μg/mL LPS for 24 hours),LPS+α-MG group(stimulated with 40 μmol/L α-MG combined with 1 μg/mL LPS for 24 hours),LPS+α-MG si-NC group(transfected with 70 μg/mL si-NC and stimulated with 40 μmol/L α-MG and 1 μg/mL LPS for 24 hours),and LPS+α-MG+si-BDNF group(transfected with 70 μg/mL si-BDNF and stimulated with 40 μmol/L α-MG and 1 μg/mL LPS for 24 hours).CCK-8 assay was used to detect the proliferative viability of chondrocytes and macrophages in each group,and flow cytometry was used to detect the apoptosis of chondrocytes and the polarization of macrophages.ELISA was used to detect the levels of interleukin(IL)-1β,IL-6,and tumor necrosis factor(TNF)-α of chondrocytes in each group.Western blot was used to detect the expression of BDNF,PI3K,and Akt in chondrocytes and macrophages.Results In chondrocytes,compared with the control group,the LPS group had decreased cell proliferation rate,increased cell apoptosis rate,down-regulated expression of BDNF,PI3K and Akt proteins,and up-regulated levels of IL-1β,IL-6 and TNF-α(P<0.05);compared with the LPS group,the LPS+α-MG group showed increased cell proliferation rate,decreased cell apoptosis rate,up-regulated expression of BDNF,PI3K and Akt proteins,and down-regulated levels of IL-1β,IL-6 and TNF-α(P<0.05);compared with the LPS+α-MG+si-NC group,the LPS+α-MG si-BDNF group demonstrated decreased cell proliferation rate,increased cell apoptosis rate,down-regulated expression of BDNF,PI3K and Akt proteins,and increased levels of IL-1β,IL-6 and TNF-α(P<0.05).In macrophages,compared with the control group,the LPS group had decreased cell proliferation rate,increased proportion of M1 cells,and down-regulated expression of BDNF,PI3K and Akt proteins(P<0.05);compared with the LPS group,the LPS+α-MG group showed increased cell proliferation rate,decreased proportion of M1 cells,and up-regulated expression of BDNF,PI3K and Akt proteins(P<0.05);compared with the LPS+α-MG+si-NC group,the LPS+α-MG+si-BDNF group showed decreased cell proliferation rate,increased proportion of M1 cells,and down-regulated expression of BDNF,PI3K and Akt proteins(P<0.05).Conclusion α-MG inhibits the M1 polarization of macrophages to improve the apoptosis and inflammation of rat chondrocytes by activating the BDNF/PI3K/Akt signaling pathway.

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 summarise the main points of operation during thyroid surgery using bilateral axillo-breast approach (BABA) with a domestic robot and to analyse the learning curve.Methods:From May. 2023 to Oct. 2023, we retrospectively analysed the clinical data of 38 patients who underwent thyroid surgery with domestically manufactured robot via BABA attending the Department of Thyroid and Breast Surgery of the 960th Hospital of PLA Joint Logistics Support Force, proposed and constructed learning curves using cumulative and analytical methods to study the minimum number of learning cases required for the loading time of assistants and surgeon-in-charge with da Vinci surgical experience to transition from the initial learning stage to the proficiency stage. The age, BMI, surgical time (loading time, operating time), postoperative drainage time, and number of lymph nodes dissected were compared among patients at different stages of the learning curve.Results:A total of 38 thyroidectomy patients successfully underwent surgery, with an average surgical time of (176.61 ± 47.98) minutes. After 18 cases, the assistant's loading time shortened and stabilized at (42.20 ± 3.44) minutes. The operator reached peak proficiency at the 18th case (loading time, operating time), which was considered the dividing point between the learning phase and the proficiency phase. During the learning phase, the average surgical time was (209.72 ± 49.28) minutes, operation time: (165.44 ± 49.93) minutes, while in the proficiency phase, the average surgical time decreased to 146.80 ± 18.34 minutes, operation time: (104.60 ± 19.01) minutes. There were no statistically significant differences in baseline characteristics such as age, BMI, postoperative drainage time, or the number of central compartment lymph nodes dissected between the two phases ( P > 0.05) . Conclusion:Over the results of this study, it was shown that for robosurgeons with experience in da Vinci robotic surgery, the transition from the learning stage to the proficiency stage could be considered after crossing the learning curve for 18 cases, and that assistants could become proficient in loading techniques after 18 procedures.
