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.

At present, the process and methodology of patient guidelines (PGs) development varies greatly and lacks systematic and standardised guidance. In addition to the interviews with PG developers, we have sorted out the relevant methodology for the adaptation and development of existing clinical practice guideline recommendations and facilitated expert deliberations to achieve a consensus, so as to finally put forward a proposal for guidance on the process and methodology for the development of PGs. The development of PGs can be divided into the preparation stage, the construction stage, and the completion stage in general, but the specific steps vary according to the different modes of development of PGs. The development process of Model 1 is basically the same as the patient version of the guideline development process provided by the International Guidelines Network, i.e., team formation, screening of recommendations, guideline drafing, user testing and feedback, approval and dissemination. The developer should also first determine the need for and scope of translating the clinical practice guideline into a patient version during the preparation phase. Model 2 adds user experience and feedback to the conventional clinical practice guideline development process (forming a team, determining the scope of the PG, searching, evaluating and integrating evidence, forming recommendations, writing the guideline, and expert review). Based on the different models, we sort out the process and methods of PG development and introduce the specific methods of PG development, including how to identify the clinical problem and how to form recommendations based on the existing clinical practice guidelines, with a view to providing reference for guideline developers and related researchers.

Ubiquitination is a crucial post-translational modification process that can degrade proteins within cells and plays a vital role in maintaining protein homeostasis and abundance.Deubiquitinating enzymes(DUBs)are important proteases in the ubiquitin system.They reverse the ubiquitination process by cleaving protein chains and recycling ubiquitin molecules to regulate protein stability.Abnormal deubiquitinating enzyme activity is related to the occurrence and development of many malignant tumors.JOSD2,a DUB,is a member of the Machado-Joseph disease protein domain protease(MJD)family and characterized by a single highly conserved catalytic Josephin domain.Increasing studies have revealed a connection between JOSD2 and malignant tumors.This article elaborates on the current research status of DUBs,particularly JOSD2,in malignant tumors.Results suggest that JOSD2 is a potential target for the treatment of malignant tumors.

Endo-beta-N-acetylglucosaminidase (ENGase) is widely distributed in various organisms. The first reported ENGase activity was detected in Diplococcus pneumoniae in 1971. The protein (Endo D) was purified and its peptide sequence was determined in 1974. Three ENGases (Endo F1-F3) were discovered in Flavobacterium meningosepticum from 1982 to 1993. After that, the activity was detected from different species of bacteria, yeast, fungal, plant, mice, human, etc. Multiple ENGases were detected in some species, such as Arabidopsis thaliana and Trichoderma atroviride. The first preliminary crystallographic analysis of ENGase was conducted in 1994. But to date, only a few ENGases structures have been obtained, and the structure of human ENGase is still missing. The currently identified ENGases were distributed in the GH18 or GH85 families in Carbohydrate-Active enZyme (CAZy) database. GH18 ENGase only has hydrolytic activity, but GH85 ENGase has both hydrolytic and transglycosylation activity. Although ENGases of the two families have similar (β/α)8-TIM barrel structures, the active sites are slightly different. ENGase is an effective tool for glycan detection andglycan editing. Biochemically, ENGase can specifically hydrolyze β‑1,4 glycosidic bond between the twoN-acetylglucosamines (GlcNAc) on core pentasaccharide presented on glycopeptides and/or glycoproteins. Different ENGases may have different substrate specificity. The hydrolysis products are oligosaccharide chains and a GlcNAc or glycopeptides or glycoproteins with a GlcNAc. Conditionally, it can use the two products to produce a new glycopeptides or glycoprotein. Although ENGase is a common presentation in cell, its biological function remains unclear. Accumulated evidences demonstrated that ENGase is a none essential gene for living and a key regulator for differentiation. No ENGase gene was detected in the genomes of Saccharomyces cerevisiae and three other yeast species. Its expression was extremely low in lung. As glycoproteins are not produced by prokaryotic cells, a role for nutrition and/or microbial-host interaction was predicted for bacterium produced enzymes. In the embryonic lethality phenotype of the Ngly1-deficient mice can be partially rescued by Engase knockout, suggesting down regulation of Engase might be a solution for stress induced adaptation. Potential impacts of ENGase regulation on health and disease were presented. Rabeprazole, a drug used for stomach pain as a proton inhibitor, was identified as an inhibitor for ENGase. ENGases have been applied in vitro to produce antibodies with a designated glycan. The two step reactions were achieved by a pair of ENGase dominated for hydrolysis of substrate glycoprotein and synthesis of new glycoprotein with a free glycan of designed structure, respectively. In addition, ENGase was also been used in cell surface glycan editing. New application scenarios and new detection methods for glycobiological engineering are quickly opened up by the two functions of ENGase, especially in antibody remodeling and antibody drug conjugates. The discovery, distribution, structure property, enzymatic characteristics and recent researches in topical model organisms of ENGase were reviewed in this paper. Possible biological functions and mechanisms of ENGase, including differentiation, digestion of glycoproteins for nutrition and stress responding were hypothesised. In addition, the role of ENGase in glycan editing and synthetic biology was discussed. We hope this paper may provide insights for ENGase research and lay a solid foundation for applied and translational glycomics.

Standardized reporting is a crucial factor affecting the use of patient guidelines (PGs), particularly in the reporting and presentation of recommendations. This paper introduced the current status of PG reporting, including the research on PG content and presentation formats, and provided comprehensive recommendations for PG reporting from aspects such as overall framework, recommendations, presentation format, and readability. First, the presentation of PG recommendations should include clearly defined clinical questions, recommendations and their rationale, and guidance on how patients should implement the interventions; for specific content in the PG, such as level of evidence, level of recommendation, it is recommended to explain in text the reasons for giving different levels of recommendation, i.e., to present the logic behind giving the level of recommendation to the patient; additional information needed in the recommendation framework should be supplemented by tracing references or authoritative textbooks and literature that support the recommendations. Subsequently, the PG text should be written based on the Reporting Checklist for Public Versions of Guidelines (RIGHT-PVG) reporting framework. Finally, to enhance readability and comprehension, it is recommended to refer to the Patient Education Materials Assessment Tool (PEMAT) for translating PG content. To enhance the readability of PGs, it is suggested to present the PG content in a persona-lized and layered manner.

Objective:To explore the effect of Kangfuxin solution combined with triamcinolone and Econazole cream in elderly patients with hip fracture complicated with incontinence dermatitis, and to provide reference for clinical nursing.Methods:A randomized controlled trial was conducted to select 80 elderly patients with hip fracture complicated with incontinence dermatitis who were hospitalized in the Orthopedics Department of the First Medical Center of the PLA General Hospital from February 2023 to March 2024 by convenient sampling method. They were divided into the experimental group and the control group with 40 cases in each group according to random number table method. The experimental group was treated with Kangfuxin solution combined with triamcinolone and econazole cream for incontinence dermatitis. Intervention was stopped after 2 weeks of intervention or the incontinence dermatitis reached the clinical healing standard. In the control group, 3M spray was used to care the affected area of incontinence dermatitis, intervention was stopped after 2 weeks or the incontinence dermatitis reached the clinical healing standard. Incontinence dermatitis Skin Injury Assessment Scale (IADS) and perineal skin assessment tool PAT were used to evaluate the skin status of the two groups, and the healing time and treatment effectiveness of the two groups were compared.Results:In the control group, there were 11 males and 29 females, with age of (76.53 ± 8.67)years. There were 9 males and 31 females in the experimental group, with age of (76.56 ± 8.69)years, and there was no significant differences in baseline data between the two groups (all P>0.05). After intervention, the IADS and PAT scores of the control group were (27.13±5.22) points and (5.11 ± 0.94) points respectively, which were significantly higher than those of the experimental group (25.43 ± 4.15) points and (3.73 ± 1.21) points, and the differences were statistically significant ( t=7.22, 8.21, both P<0.05). The effective treatment in the experiment group was 97.5% (39/40), which was significant higher than 72.5% (29/40) in the control group ( χ2=13.25, P<0.05). The healing time of experimental group was (4.57 ± 3.44) d, which was significantly shorter than that of control group (9.23 ± 4.19) d, with statistical significance ( t=11.61, P<0.05). Conclusions:The combined application of Kangfuxin solution and triamcinolone and Econazole cream has a significant effect on improving incontinence dermatitis and perineal health in elderly patients with hip fracture, can effectively reduce symptoms and accelerate skin healing, and has certain clinical application value.
