Objectives:To observe the clinical characteristics of familial chylomicronemia syndrome (FCS) in Chinese population and explore the suitable diagnostic criteria of FCS in China.Methods:We screened 6856 patients with triglyceride ≥10 mmol/L from 9 hospitals in China between January 2010 and December 2023.The overall clinical information was collected and FCS-related gene testing was performed in 102 patients with high suspicion of FCS.Demographic characteristics were analyzed and FCS diagnosis was drafted.The FDA FCS diagnostic criteria was used to verify the FCS patients diagnosed in this study.At the same time,the prevalence of FCS patients with fasting triglyceride ≥10 mmol/L was explored in some of the above hospitals.Results:In this study,the diagnostic criteria for FCS in Chinese population were drafted based on European and American diagnostic criteria and Chinese clinical practice:(1) Fasting triglyceride ≥ 10 mmol/L after standard lipid-lowering treatment;(2) With one of the below-listed conditions:positive detection of FCS related genes;family history of hypertriglyceridemia pancreatitis (HTGP);history of pancreatitis in adolescence or adult HTGP;history of repeated hospitalization with unexplained abdominal pain.According to this criteria,60 were preliminarily diagnosed with FCS from the 102 patients enrolled.Their average age was (43.0±8.6) years old,male accounted for 70％,average triglyceride was (20.0±15.0) mmol/L.FCS related gene mutations were detected in 6 patients,all were lipoprotein lipase gene mutations.According to the American FCS diagnostic criteria,among the 60 FCS patients diagnosed in this study,the proportion of patients with "possible FCS" was 98.3％ (59/60),and the proportion of patients with "confirmed FCS" was 70.0％ (42/60).According to the diagnostic criteria of FCS patients in this study,the prevalence of FCS patients with TG ≥10 mmol/L is about 0.5％ (33/6722).Conclusions:The clinical and genetic characteristics of Chinese patients with FCS are consistent with those of European and American patients.The diagnostic criteria for FCS drafted in this study can be further verified and promoted in Chinese population.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in healthcare facilities in major regions of China in 2023.Methods Clinical isolates collected from 73 hospitals across China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2023 Clinical & Laboratory Standards Institute (CLSI) breakpoints.Results A total of 445199 clinical isolates were collected in 2023,of which 29.0％ were gram-positive and 71.0％ were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species (excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi) (MRSA,MRSE and MRCNS) was 29.6％,81.9％ and 78.5％,respectively.Methicillin-resistant strains showed significantly higher resistance rates to most antimicrobial agents than methicillin-susceptible strains (MSSA,MSSE and MSCNS).Overall,92.9％ of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 91.4％ of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis had significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 93.1％ in the isolates from children and and 95.9％ in the isolates from adults.The resistance rate to carbapenems was lower than 15.0％ for most Enterobacterales species except for Klebsiella,22.5％ and 23.6％ of which were resistant to imipenem and meropenem,respectively .Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.6％ to 10.0％.The resistance rate to imipenem and meropenem was 21.9％ and 17.4％ for Pseudomonas aeruginosa,respectively,and 67.5％ and 68.1％ for Acinetobacter baumannii,respectively.Conclusions Increasing resistance to the commonly used antimicrobial agents is still observed in clinical bacterial isolates.However,the prevalence of important crabapenem-resistant organisms such as crabapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a slightly decreasing trend.This finding suggests that strengthening bacterial resistance surveillance and multidisciplinary linkage are important for preventing the occurrence and development of bacterial resistance.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Sturgeon cartilage has a wide range of applications as it is rich in biologically active substances such as chondroitin sulphate and protein. In this study, the safety evaluation of sturgeon cartilage peptide in NIH/3T3 and C2C12 cells was conducted, and the results showed that sturgeon cartilage peptide did not induce apoptosis and necrosis in NIH/3T3 and C2C12 cells compared to the blank control, which provides an in vitro experimental basis for the transdermal drug delivery of sturgeon cartilage peptide. Further evaluation of the scavenging activity of sturgeon cartilage peptides against the 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals showed that sturgeon cartilage peptides have strong antioxidant activity. A stable sturgeon cartilage peptide ointment containing 7% sturgeon cartilage peptide was prepared and analysed for its transdermal absorption in mouse skin. This experiment was approved by the Animal Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences (approval number: 00007684). It was found that the 12-hour cumulative release of sturgeon cartilage peptide ointment reached 92%. In this study, we further analyzed the ability of sturgeon cartilage peptide ointment to inhibit ear swelling in mice after xylene-induced inflammation. The sturgeon cartilage peptide ointment showed significant anti-inflammatory activity compared to the matrix group and the control group. In conclusion, the present study clearly demonstrated that sturgeon cartilage peptide has good safety and antioxidant activity, and the prepared sturgeon cartilage peptide ointment provides an experimental basis for further application of sturgeon cartilage peptide as well as the study of transdermal drug delivery.
