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 The traditional round incision or cross incision brain harvesting method can not meet the requirements of protecting the donor's remains. In this study, the method of brain removal through a posterior incision on the scalp of both ears was proposed, which effectively protected the donor's remains. Methods Adopting the incision 2. 0 cm above the external occipital protuberance to the most front edge of the auricle to obtain a complete brain. Results The incision did not involve the head and face skin, which was small and conducive to suture repair and reduce exudation. Conclusion The incision effectively protects the donor' s remains, and it will be conducive to the establishment and development of the brain bank.

ObjectiveTo observe the effect of asiaticoside （AC） on the expression of T helper 17 （Th17） cells and regulatory T （Treg） cells in DBA/1 mice with collagen-induced arthritis （CIA）. MethodMale SPF DBA/1 mice were randomized into six groups according to body weight： control group， CIA group， methotrexate group （MTX group， ip， 0.5 mg·kg^-1）， and AC low-， medium-， and high-dose groups （ig， 5， 15， 45 mg·kg^-1， respectively）. Modeling was performed in rats other than the control group. To be specific， they were immunized with bovine type Ⅱ collagen and complete Freund's adjuvant on the first day and with bovine type Ⅱ collagen and incomplete Freund's adjuvant on the 21^st day. Administration began on the day of the second immunization， once a day for 28 days. On the 49^th day， related tissues were collected. Then， hematoxylin-eosin （HE） staining was performed to observe the pathological changes of the joints. Immunohistochemical method was used to detect the expression of interleukin-17 （IL-17） and forkhead box protein-3 （FoxP3）， the markers of Th17 and Treg cells， respectively， immunofluorescence double staining the expression of IL-17 and FoxP3 in CD4⁺T cells of mouse joint tissue， and flow cytometry the proportions of Th17 and Treg cells in mouse lymph nodes. ResultCompared with the control group， CIA group demonstrated joint disorder， damage of articular cartilage and bone， severe bone erosion （P<0.01）， increase in stained CD4 and IL-17 and the integral absorbance （IA） （P<0.01）， decrease in stained FoxP3 and the IA （P<0.01）， rise of Th17/Treg ratio （P<0.01）， elevation of Th17 expression in mouse lymph nodes （P<0.01）， and reduction in Treg expression （P<0.01）. Compared with CIA group， MTX group and three AC groups showed normal joints， alleviated bone erosion and damage， intact and smooth joint surface， and decrease in stained IL-17 and IA （P<0.05， P<0.01）， and MTX group and AC medium-dose and high-dose groups registered decrease in stained CD4 and IA （P<0.01） and reduction in Th17/Treg ratio （P<0.05， P<0.01）. Moreover， AC medium-dose and high-dose groups showed rise in stained FoxP3 and IA （P<0.05， P<0.01）. In the lymph nodes of mice， decrease in expression of Th17 cells （P<0.05， P<0.01） and the increase in expression of Treg cells （P<0.05， P<0.01） were observed in all the three AC group. ConclusionAC can regulate Th17/Treg balance by inhibiting the expression of Th17 cells and promoting the expression of Treg cells in CIA mice.

Objective: To investigate the economic burden of bacillus Calmette-Guérin (BCG) lymphadenitis in Shandong Province. Methods: From May 2011 to December 2019, 304 patients applying for the province-level compensation of BCG lymphadenitis was selected from Shandong Province in this study. The basic situation, vaccination, outpatient (inpatient) records, cost and relevant information of those patients were collected to calculate the direct economic burden (including direct medical costs and direct non-medical costs), indirect economic burden and total economic burden. Comparison of the difference of economic burden of cases with different characteristics was taken. Results: The M(Q₁,Q₃) of age of BCG lymphadenitis patients was 3 (2, 4) months, among which 239 cases (78.6%) were male, 71 cases (23.4%) had lymphadenopathy, and 227 cases (74.7%) underwent surgery.The number of outpatient only, inpatient only and outpatient then inpatient was 25.7% (78 cases), 7.2% (22 cases) and 67.1% (204 cases), respectively. The M(Q₁,Q₃) of direct, indirect and total economic burden of single case after discount was 9 910 (5 713, 16 074), 2 081 (1 547, 3 122) and 12 262 (7 694, 18 571) yuan, respectively.The direct medical expenses accounted for 89.4% of the direct economic burden, the direct economic burden accounted for 84.9% of the total economic burden, the total economic burden of 80.0% cases accounted for only about 20.0% of the compensation amount, and the total economic burden of only 2.3% cases accounted for more than 60.0% of the compensation amount.The direct, indirect and total economic burden of patients with inpatient only and outpatient then inpatient was higher than that of patients with outpatient only; the direct, indirect and total economic burden of patients with operation was higher than that of patients with non-operation; the direct and total economic burden of patients with unulcerated lymph node was higher than that of patients with ulcerated lymph node(all P values<0.05). Conclusion: The economic burden of BCG lymphadenitis cases in Shandong Province is influenced by the mode of diagnosis and treatment, with direct medical expenses as the predominant component.

Objective:In general, patients with seropositive rheumatoid arthritis (RA) are considered to show an aggressive disease course. However, the relationship between the two subgroups in disease severity is controversial. Our study is aimed to compare the clinical characteristics and prognosis of double-seropositive and seronegative RA in China through a real-world large scale study.Methods:RA patients who met the 1987 American College of Rheumatology (ACR) classification criteria or the 2010 ACR/European Anti-Rheumatism Alliance RA classification criteria, and who attended the 10 hospitals across the country from September 2015 to January 2020, were enrolled. According to the serological status, patients were divided into 4 subgroups [rheumatoid factor (RF)(-) anti-cyclic citrullinated peptide (CCP) antibody (-), RF(+), RF(+) anti-CCP antibody(+), anti-CCP antibody(+)] and compared the disease characteristics and treatment response. One-way analysis of variance was used for measurement data that conformed to normal distribution, Kruskal-Wallis H test was used for measurement data that did not conform to normal distribution; paired t test was used for comparison before and after treatment within the group if the data was normally distributed else paired rank sum test was used; χ2 test was used for count data. Results:① A total of 2 461 patients were included, including 1 813 RF(+) anti-CCP antibody(+) patients (73.67%), 129 RF(+) patients (5.24%), 245 RF(-) anti-CCP antibody(-) patients (9.96%), 74 anti-CCP antibody(+) patients (11.13%). ② Regardless of the CCP status, RF(+) patients had an early age of onset [RF(-) anti-CCP antibody(-) (51±14) years old, anti-CCP antibody(+) (50±15) years old, RF(+) anti-CCP antibody(+) (48±14) years old, RF(+)(48±13) years old, F=3.003, P=0.029], longer disease duration [RF(-) anti-CCP antibody(-) 50 (20, 126) months, anti-CCP antibody(+) 60(24, 150) months, RF(+) anti-CCP antibody(+) 89(35, 179) months, RF(+) 83(25, 160) months, H=22.001, P<0.01], more joint swelling counts (SJC) [RF(-) anti-CCP antibody(-) 2(0, 6), Anti-CCP antibody(+) 2(0, 5), RF(+) anti-CCP antibody(+) 2(0, 7), RF(+) 2(0, 6), H=8.939, P=0.03] and tender joint counts (TJC) [RF(-) anti-CCP antibody(-) 3(0, 8), anti-CCP antibody(+) 2(0, 6), RF(+) anti-CCP antibody(+) 3(1, 9), RF(+) 2(0, 8), H=11.341, P=0.01] and the morning stiff time was longer [RF(-) anti-CCP antibody(-) 30(0, 60) min, anti-CCP antibody(+) 20(0, 60) min, RF(+) anti-CCP antibody(+) 30(10, 60) min, RF(+) 30(10, 60) min, H=13.32, P<0.01]; ESR [RF(-) anti-CCP antibody(-) 17(9, 38) mm/1 h, anti-CCP antibody(+) 20(10, 35) mm/1 h, RF(+) anti-CCP antibody(+) 26(14, 45) mm/1 h, RF(+) 28(14, 50) mm/1 h, H=37.084, P<0.01] and CRP [RF(-) anti-CCP antibody(-) 2.3 (0.8, 15.9) mm/L, Anti-CCP antibody(+) 2.7(0.7, 12.1) mm/L, RF(+) anti-CCP antibody(+) 5.2(1.3, 17.2) mm/L, RF (+) 5.2(0.9, 16.2) mm/L, H=22.141, P<0.01] of the RF(+)patients were significantly higher than RF(-) patients, and RF(+) patients had higher disease severity(DAS28-ESR) [RF(-) anti-CCP antibody(-) (4.0±1.8), anti-CCP antibody(+) (3.8±1.6), RF(+) anti-CCP antibody(+) (4.3±1.8), RF(+) (4.1±1.7), F=7.269, P<0.01]. ③ The RF(+) anti-CCP antibody(+) patients were divided into 4 subgroups, and it was found that RF-H anti-CCP antibody-L patients had higher disease severity [RF-H anti-CCP antibody-H 4.3(2.9, 5.6), RF-L anti-CCP antibody-L 4.5(3.0, 5.7), RF-H anti-CCP antibody-L 4.9(3.1, 6.2), RF-L anti-CCP antibody-H 2.8(1.8, 3.9), H=20.374, P<0.01]. ④ After 3-month follow up, the clinical characteristics of the four groups were improved, but there was no significant difference in the improvement of the four groups, indicating that the RF and anti-CCP antibody status did not affect the remission within 3 months. Conclusion:Among RA patients, the disease activity of RA patients is closely related to RF and the RF(+) patients have more severe disease than RF(-) patients. Patients with higher RF titer also have more severe disease than that of patients with low RF titer. After 3 months of medication treatment, the antibody status does not affect the disease remission rate.

OBJECTIVES: To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia. METHODS: A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis. RESULTS: Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%, CONCLUSIONS Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

Objective:To observe the effect of Fangji Huangqitang （FJHQT） on collagen induced arthritis （CIA） and synovial angiogenesis in DBA/1 mice. Method:DBA/1 mice were randomly divided into normal group， CIA group and FJHQT group. DBA/1 mice in CIA group and FJHQT group were immunized with bovine type Ⅱ collagen and complete Freund's adjuvant on the first day， and DBA/1 mice were immunized with bovine type Ⅱ collagen and incomplete Freund's adjuvant on the 21^st day to establish CIA model. On the day of the second immunization， the drug was given by gavage once a day for 28 days. On the 22^nd day， the arthritis score and other symptoms of CIA mice were observed. On the 49^th day， Hematoxylin eosin （HE） staining was carried out to observe the angiogenesis in the synovium of CIA mice， the expression of vascular endothelial cell marker platelet endothelial cell adhesion molecule-1 （CD31） and vascular endothelial growth factor （VEGF） in the synovium of CIA mice were detected. Immunofluorescence double staining was used to detect the mature and immature vessels in the synovium of CIA mice. And the microvascular growth of the rat thoracic aortic ring was induced by VEGF （20 μg·L^-1）. The effects of FJHQT （0.25， 0.5， 1 g·L^-1） at different concentrations were observed under microscope. Result:Compared with the normal group， the inflammation， joints， red and swelling of the inflammatory joints of the CIA group were significantly increased （P<0.01）. The scores of clinical arthritis， the incidence rate， synovial inflammation and angiogenesis were significantly increased （P<0.01）. The density of blood vessels， the positive expression of CD31 and VEGF， the number of immature vessels in synovial membrane were significantly increased （P<0.01）. And compared with the CIA group， the inflammation， joint swelling， and malformation of the FJHQT group were significantly improved， the clinical arthritis score， incidence rate， synovial inflammation and angiogenesis were significantly reduced （P<0.01）. The vascular density， the positive expression of CD31 and VEGF， and the number of immature blood vessels in synovial membrane were significantly increased （P<0.01）. Compared with blank group， VEGF could significantly induce the growth of microvasculature in rat thoracic aortic ring （P<0.01）. Compared with VEGF group， FJHQT（0.25， 0.5， 1 g·L^-1） could significantly inhibit the formation of microvasculature in rat thoracic aortic ring （P<0.01）. Conclusion:FJHQT can effectively alleviate the clinical symptoms and condition of CIA mice， reduce the clinical arthritis score and incidence rate，and inhibit the synovial angiogenesis of CIA mice joints and VEGF induced microvascular formation in rat thoracic aortic rings.

OBJECTIVETo discuss the present status and progress of clinical research on the cognitive effects caused by different types of brain tumors and common treatments.

DATA SOURCESThe data used in this review were mainly from PubMed articles published in English from 1990 to Febuary 2012. Research terms were "cognitive deficits" or "cognitive dysfunction".

STUDY SELECTIONArticals including any information about brain tumor related cognitive deficits were selected.

RESULTSIt is widely accepted that brain tumors and related treatments can impair cognitive function across many domains, and can impact on patients' quality of life. Tumor localization, lateralization, surgery, drugs, radiotherapy and chemotherapy are all thought to be important factors in this process. However, some conflicting findings regarding brain tumor-related cognitive deficits have been reported. It can be difficult to determine the mechanism of these treatments, such as chemotherapy, antibiotics, antiepileptics, and steroids. Future research is needed to clarify these potential treatment effects.

CONCLUSIONSCognitive function is important for patients with brain tumor. Much more focus has been paid on this field. It should be regarded as an important prognostic index for the patients with brain tumor, and neuropsychological tests should be used in regular examinations.

OBJECTIVETo study the expression of stromal cell derived factor-1(SDF-1) and CXC chemokine receptor 4 (CXCR4) in the airway and the effect of budesonide on their expression in mice with asthma.

METHODSThirty BALB/c male mices were randomly divided into three groups: placebo control, untreated asthma, and budesonide-treated asthma. The asthma group were induced by intraperitoneal injection of 10% ovalbumin (OVA ) on days 1, 8 and 15, and then from days 22 to 34, challenged by inhalation of 2% OVA aerosol every other day. The budesonide-treated asthma group received an inhalation of budesonide (1 mg ) before OVA challenge. The pathological changes of the airway were assessed by hematoxylin and eosin staining. The immunohistochemistry was used to estimate the expression of SDF-1 in the lung. RT-PCR was used to evaluate the expression of CXCR4 in the lung.

RESULTSCompared with the control group, SDF-1 and CXCR4 expression in the lung in the untreated asthma group increased significantly (p<0.05). The budesonide-treated asthma group demonstrated significantly decreased SDF-1 (0.426+/-0.052 vs 0.361+/-0.065; p<0.05) and CXCR4 (0.829+/-0.027 vs 0.723+/-0.094; p<0.05) expression in the lung as compared with the untreated asthma group. Both SDF-1 (r=0.744, p<0.01) and CXCR4 (r=0.553, p<0.01)were positively correlated with the thickness of the airway wall.

CONCLUSIONSSDF-1 and CXCR4 may be associated with airway remodeling in mice with asthma. Budesonide can improve airway remodeling, possibly by decreasing the expression of SDF-1 and CXCR4.
