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 further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province.Methods:This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized.Results:Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion:Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.

Objective:To compare the consistency of lymphoma multigene detection panels based on next-generation sequencing (NGS) with FISH detection of B-cell lymphoma gene rearrangement.Methods:From January 2019 to May 2023, fusion genes detected by lymphoma-related 413 genes that targeted capture sequencing of 489 B-cell lymphoma tissues embedded in paraffin were collected from Henan Cancer Hospital, and the results were compared with simultaneous FISH detection of four break/fusion genes: BCL2, BCL6, MYC, and CCND1. Consistency was defined as both methods yielding positive or negative results for the same sample. The relationship between fusion mutation abundance in NGS and the positivity rate of cells in FISH was also analyzed.Results:Kappa consistency analysis revealed high consistency between NGS and FISH in detecting the four B-cell lymphoma-related gene rearrangement ( P<0.001 for all) ; however, the detection rates of positive individuals differed for the four genes. Compared with FISH, NGS demonstrated a higher detection rate for BCL2 rearrangement, a lower detection rate for BCL6 and MYC rearrangement, and a similar detection rate for CCND1 rearrangement. No correlation was found between fusion mutation abundance in NGS and the positivity rate of cells in FISH. Conclusions:NGS and FISH detection of B-cell lymphoma gene rearrangement demonstrate overall good consistency. NGS is superior to FISH in detecting BCL2 rearrangement, inferior in detecting MYC rearrangement, and comparable in detecting CCND1 rearrangement.

Objective:To investigate the efficacy and safety of tenofovir amibufenamide in patients over 65 years old with chronic hepatitis B and liver cirrhosis.Methods:We recruited 45 patients in Linyi People's Hospital with chronic hepatitis B and liver cirrhosis who were treated with TMF antiviral therapy for 48 weeks, compared the virologic response rate and HBV DNA decrease level at 12, 24 and 48 weeks, and the changes in hepatitis B surface antigen, alanine aminotransferase, glomerular filtration rate, creatinine, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, serum phosphorus and blood lipids, and the changes in ALT normalization rate at 48 weeks. P<0.05 was statistically significant. Results:The age of the enrolled patients was 69.0 (67.0, 72.5) years. At 12, 24, and 48 weeks of treatment, the complete virological response rates were 32.4% (12/37), 70.0% (28/40), and 84.6% (33/39) respectively, and the level of HBV DNA decreased from baseline ( P＜0.05). After 48 weeks of treatment, the level of HBsAg decreased ( P<0.05), and there was no negative HBsAg conversion and seroconversion. After 48 weeks of treatment, the level of ALT decreased ( P<0.05). At 48 weeks of treatment, the rates of ALT reverted to normality were 88.9% (16/18) and 70.4% (19/27), respectively. There was no significant difference in the levels of glomerular filtration rate, creatinine, phosphorus, triglycerides, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol estimated at baseline before and after treatment ( P＞0.05), and no serious adverse events were observed. Conclusions:For patients over 65 years old with chronic hepatitis B and liver cirrhosis, TMF can significantly inhibit HBV DNA replication, and the ALT normalization rate is high and well tolerated.

BACKGROUND:Our previous studies have confirmed that H2O2 and ginsenoside Rg1 can cause changes in reactive oxygen species levels in human periodontal ligament cells,but the correlation of reactive oxygen species with apoptosis and autophagy remains unclear. OBJECTIVE:To explore the effect and mechanism of ginsenoside Rg1 on H2O2-induced apoptosis and autophagy of human periodontal ligament cells. METHODS:Human periodontal ligament cells were divided into control group,H2O2 group and H2O2+Rg1 group.Ginsenoside Rg1(50 μmol/L)was pre-incubated for 24 hours and H2O2 was treated for 2 hours(500 μmol/L).CCK-8 assay was used to detect the proliferation ability of the cells.A fluorescent probe DCFH-DA was used to detect the reactive oxygen species level of the cells.qRT-PCR and western blot assay were used to detect heme oxygenase 1,apoptosis-related factor Caspase-3,Bax,anti-apoptotic factor Bcl-2,autophagy Beclin-1,P62,LC3,pathway-related factors phosphatidylinositol-3-kinase(PI3K),protein kinase B(AKT),mammalian target of rapamycin(mTOR)mRNA and protein expression. RESULTS AND CONCLUSION:(1)Compared with the control group,the proliferation activity of human periodontal ligament cells in the H2O2 group decreased.Compared with the H2O2 group,the proliferation activity of human periodontal ligament cells increased in the H2O2+Rg1 group.(2)Compared with the control group,the expression of reactive oxygen species and heme oxygenase-1 increased in the H2O2 group.Compared with the H2O2 group,the expression of reactive oxygen species and heme oxygenase-1 decreased in the H2O2+Rg1 group.(3)Compared with the control group,the expression of Caspase-3,Bax,Beclin-1 and LC3 increased,while the expression of Bcl-2 and P62 decreased in human periodontal ligament cells of the H2O2 group.Compared with the H2O2 group,the expressions of Caspase-3,Bax,Beclin-1 and LC3 decreased,and the expressions of Bcl-2 and P62 increased in the H2O2+Rg1 group.(4)Compared with the control group,the expressions of PI3K,AKT and mTOR decreased in human periodontal ligament cells of the H2O2 group.Compared with the H2O2 group,the expressions of PI3K,AKT and mTOR increased in human periodontal ligament cells of the H2O2+Rg1 group.(5)These results suggest that ginsenoside Rg1 can inhibit H2O2-induced apoptosis and autophagy in human periodontal ligament cells by reducing the content of reactive oxygen species and down-regulating the related factor expression of the PI3K/AKT/mTOR pathway.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.
