Objective:To establish a method for preserving viral nucleic acids in plasma using a blood collection card based on the dry spot method,to predict the duration of nucleic acid preservation by establishing the Arrhenius equation,and to demonstrate the feasibility of this preservation method for the re-testing of nucleic acids in blood samples retained by blood banks.Methods:Plasma samples positive for HBV,HCV,and HIV nucleic acids were prepared into preservation cards in the form of dry plasma spots for storage.The prepared preservation cards were placed under accelerated storage conditions at 37,45,50,and 55 ℃.The preservation cards were periodically retrieved from each temperature condition for nucleic acid extraction,and the nucleic acid samples were purified for subsequent PCR testing,with the recorded CT values.An Arrhenius equation model was established between the expiration time and the storage temperature,thereby predicting the validity period of nucleic acid preservation in blood collection cards under specified storage temperature conditions.Results:For the plasma samples positive for HBV,HCV,and HIV nucleic acids preserved using the dry spot method,the regression equations for the duration with temperature were as follows:y=-11546x+31.74 for HBV,y=-12949x+36.88 for HCV,and y=-12204x+34.48 for HIV,with the correlation coefficient r greater than 0.98 for all.It was predicted that at a storage temperature of 4 ℃,the preservation periods for HBV,HCV,and HIV viral nucleic acids using the dry spot method would be 20792 days,19289 days,and 14285 days,respectively.At a storage temperature of 20 ℃,the preservation periods would be 2135 days 1502 days,and 1289 days,respectively.Conclusion:The nucleic acids of the three common viral pathogens in blood samples,when preserved using the dry spot method,conform to a first-order reaction pattern in the accelerated degradation experiment.The relationship between the rate of nucleic acid degradation and the absolute temperature of storage is consistent with the Arrhenius equation.Based on the calculations using this equation,the stability and validity period of plasma nucleic acid samples preserved using the dry spot method can reach a minimum of 3 .5 years under storage conditions not exceeding 20 ℃,which essentially meets the requirements for the preservation period of blood samples retained by blood banks.

Objective To explore the effects of gypenosides(Gyp)on proliferation,apoptosis,and glycolysis of ovarian cancer cells,and exploring its impact on methyltransferase-like3(METTL3)mediated N6-methyladenosine(m6A)methylation in ovarian cancer and its mechanism of action.Methods The SKOV3 cells were divided into blank group(0.9％NaCl)and experimental-L,-M,-H groups(100,200 and 300 μg·mL-1 Gyp).The glucose consumption in cells were measured by kit.The expression levels of METTL3 mRNA were measured by quantitative real-time polymerase chain reaction(RT-qPCR).The apoptosis was determined by flow cytometry.Ovarian cancer model was constructed by subcutaneous injection of ovarian cancer SKOV 3 cell)in nude mice.After successful mold formation,10 mice were randomly divided into control group(0.9％NaCl)and experimental-L,-M,-H groups(50,100 and 150 mg·kg-1 Gyp),with 10 mice in each group.The RT-qPCR were used to detected the mRNA expression of glucose transporter 1(GLUT1)and hexokinase 2(HK2)in transplanted tumors.Results In SKOV3 cells,the glucose consumption of experimental-M,experimental-H and blank groups were(7.29±0.67),(6.15±0.22)and(15.69±0.70)μmol/1×105 cells;the relative expression levels of METTL3 mRNA were 0.47±0.01,0.30±0.01 and 1.02±0.01;the apoptosis rates were(13.52±0.50)％,(14.26±1.30)％and(3.50±0.78)％;the above indexes were statistically different between the experimental-M,-H groups and the blank group(all P＜0.01).In ovarian cancer transplantation tumor in nude mice,the relative expression levels of GLUT1 mRNA in experimental-M,experimental-H and blank groups were 0.52±0.03,0.29±0.01 and 1.02±0.02;the relative expression levels of HK2 mRNA were 0.54±0.04,0.32±0.01 and 1.01±0.02;the differences of above indexes were statistically significant between the experimental-M,-H groups and the blank group(all P＜0.01).Conclusion Gypenosides may exert anticancer effects in ovarian cancer by inhibiting glycolysis,which may be related to the inhibition of METTL3 mediated m6A methylation.

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.
