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 explore the type and control measure of black dot⁃like contaminants in cell cultures. Methods: The growth state of bacteria was investigated under an inverted microscope ; Their morphological characteristics were analyzed by Gram and auramine O staining as well as electron microscopy; 16S rDNA gene sequencing was used to analyze bacterial species ; Drug sensitivity test was used to screen antibiotics against the bacteria;Cryopreserved SH⁃SY5Y cells were resuscitated by cell culture supernatant of RAW264 cells. Results: Inverted microscopic real⁃time observations showed that black dot⁃like substances had two growth states : static and moving.They were negative for Gram staining while positive for auramine O staining. Electron microscopy revealed that they were short rod⁃shaped bacteria with a polar flagellum during moving phase. 16S rDNA gene sequencing showed that these bacteria were phenylobacterium zucineum HLK1. Ceftriaxone , carboxycillin and imipenem were screened by drug sensitivity test to have inhibitory effects on the bacteria , but cell culture experiments showed that they could not remove the bacteria from SH⁃SY5Y cells. Contaminated cells could not be cryopreserved for a long time , but resuscitation with RAW264. 7 cell culture supernatant significantly improved the survival rate of cells. Conclusion The black dot⁃like contaminants in cell cultures are a special type of oligotrophic bacterium with strong viability that can invade the cells and cannot be cleared with antibiotic treatment. RAW264. 7 cell culture supernatant seems contain some substances against bacteria , and resuscitating frozen cells with RAW264. 7 cell culture supernatant may significantly improve the survival rate of cells.

Objective:This paper is to propose a calibration model based on sine function which enables more choices to determine the functional relationship between the absorbance and the concentration of the tested substance.Methods:This paper uses Taylor series expansion and Levenberg-Marquardt to obtain the optimal parameters for the Sine model and then summarizes the characters of the Sine model. On the basis of these characters, this paper compares and evaluates the experimental data processed by the Sine model from four aspects: correctness, precision, linearity and correlation.Results:The generated sine function calibration model achieved deviations within ±3% of the national standard substance, precision ( CV%) less than 2%, and a linear correlation coefficient greater than 0.990 within the measurement range of 32-710 mg/L. The correlation coefficients between the sine model and other well-performing linear calibration models for 104 clinical samples were all greater than 0.990. Conclusions:The performance evaluation of the prealbumin assay kit using the sine function calibration model meets industry standards and shows good correlation with the results of clinical sample measurements. This indicates that the sine function calibration model can serve as a new calibration model for in vitro diagnostic research and clinical applications.

Eucommiae Folium(EF),a traditional Chinese medicine,has been used to treat secondary hypertension,including renal hypertension and salt-sensitive hypertension,as well as hypertension caused by thoracic aortic endothelial dysfunction,a high-fat diet,and oxidized low-density lipoprotein.The antihyperten-sive components of EF are divided into four categories:flavonoids,iridoids,lignans,and phenyl-propanoids,such as chlorogenic acid,geniposide acid and pinoresinol diglucoside.EF regulates the occurrence and development of hypertension by regulating biological processes,such as inhibiting inflammation,regulating the nitric oxide synthase pathway,reducing oxidative stress levels,regulating endothelial vasoactive factors,and lowering blood pressure.However,its molecular antihypertensive mechanisms are still unclear and require further investigation.In this review,by consulting the relevant literature on the antihypertensive effects of EF and using network pharmacology,we summarized the active ingredients and pharmacological mechanisms of EF in the treatment of hypertension to clarify how EF is associated with secondary hypertension,the related components,and underlying mechanisms.The results of the network pharmacology analysis indicated that EF treats hypertension through a multi-component,multi-target and multi-pathway mechanism.In particular,we discussed the role of EF tar-gets in the treatment of hypertension,including epithelial sodium channel,heat shock protein70,rho-associated protein kinase 1,catalase,and superoxide dismutase.The relevant signal transduction path-ways,the ras homolog family member A(RhoA)/Rho-associated protein kinase(ROCK)and nicotinamide adenine dinucleotide phosphate(NADPH)oxidase/eNOS/NO/Ca2+pathways,are also discussed.

【Objective】 To investigate the negative emotions among university students during home quarantine under the epidemic of coronavirus disease 2019 (COVID-19) so as to provide scientific basis for psychological counseling. 【Methods】 We conducted an online questionnaire survey to collect 405 undergraduates’ and postgraduates’ DASS-21 scale scores and responses to epidemic prevention knowledge, and analyzed the university students’ negative emotions during the epidemic and influencing factors. 【Results】 Of the 405 students surveyed, 178 individuals (44.0%) had depression, 171(42.2%) felt anxious, and 119(29.4%) felt stressed. Individuals in the DASS21+ group spent much time on entertainment on the cell phone daily than those in the DASS21- group (P<0.001), and the degree of impact by COVID-19 on daily life was significantly higher (P<0.001). Correlation analysis showed that entertainment time on the cell phone, the severity of COVID-19, and the impact of the epidemic were positively related to DASS-21 scores, with correlation coefficients of 0.231, 0.143 and 0.259, respectively (all P<0.01). Binary logistic regression analysis found that mobile entertainment time for over 5 hours per day (OR=3.370, 95% CI: 1.369-8.294, P=0.008) was a risk factor for negative emotions during quarantine at home. 【Conclusion】 During quarantine at home in the epidemic of COVID-19, nearly half of university students are prone to breed negative emotions, like depression, anxiety or stress, which may be related to long-term mobile phone entertainment.

Objective To study the expression of TFIIB-related factor 2 (BRF2) in hepatocellular carcinoma(HCC) and to determine its clinical significance.Methods 80 HCC patients who received ‘curative' hepatectomy at the Qilu Hospital were studied.Immunohistochemistry analysis was performed to examine the expression of BRF2 and CD34 (microvessel density) in tumor tissues,matched paraneoplastic tissues,and normal liver tissues.Statistical methods were performed to analyse the relationships of expressions of BRF2 and CD34 with clinicopathologic factors.Results BRF2 protein was expressed at a high rate of 61.3％ in HCC tumor,which was significantly higher than that in normal liver tissues and matched paraneoplastic tissues (31.6％,28.8 ％,respectively,P ＜ 0.05).BRF2 was significantly associated with tumor differentiation,number of nodules,tumor encapsulation,TNM stage,and microvessel density.Prognosis of the high expression BRF2 group was poor.The recurrence and metastasis rates in the high expression group were significantly higher than the low expression group (P ＜ 0.05).The survival rate in the high expression group was significantly lower than the low expression group (P ＜ 0.05).Conclusions The expression of BRF2 increased in HCC tissues,and its expression was closely associated with pathological features and prognosis of patients,indicating that it can be used as a predictor in assessing prognosis of patients with HCC.

Objective To investigate the expression of Semaphorin3B (SEMA3B) in hepatocellular carcinoma (HCC) and reveal its clinical significance.Methods Immunohistochemistry and Western blotting were performed to examine the expression of SEMA3B protein in 56 hepatocellular carcinoma samples,matched perineoplastic tissues and 14 normal liver samples.Microvessel density (MVD) was determined by counting CD34-positive endothelial cells.Statistical methods were performed to analyse the relationships between the expression of SEMA3B and clinicopathologic factors.Results The rate of the SEMA3B-positive in HCC tissues was 42.9％ and significantly lower than that in normal liver tissues and non-cancerous adjacent liver tissues(78.6％ and 85.7％,respectively)(P＜0.05).MVD in SEMA3B-positive HCC tissus was lower than that in SEMA3B-negative HCC tissus (P＜0.05).The expression of SEMA3B was closely related to tumor nodular number,tumor size,tumor capsulation and CLIP score (P＜0.05 for all).The recurrence and metastasis rate in SEMA3B-positive group was lower than that in the negative group(P＜0.05),and the survival rate in positive group was higher than that in the negative(P＜0.05).Conclusion The expression of SE-MA3B was decreased in HCC tissues,and its expression was closely associated with tumor progression,angiogenesis and prognosis,indicating that it might seve as a predictor of prognosis and a possible novel target of antiangiogenic therapy for patients with HCC.
