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 investigate clinicopathological features of multinodular and vacuolar neurodegenerative tumor (MVNT) of the cerebrum, and to investigate its immunophenotype, molecular characteristics and prognosis. Methods: Four cases were collected at the General Hospital of Southern Theater Command, Guangzhou, China and one case was collected at the First People's Hospital of Huizhou, China from 2013 to 2021. Clinical, histological, immunohistochemical and molecular characteristics of these five cases were analyzed. Follow-up was carried out to evaluate their prognoses. Results: There were four females and one male, with an average age of 42 years (range, 17 to 51 years). Four patients presented with seizures, while one presented with discomfort on the head. Pre-operative imaging demonstrated non-enhancing, T2-hyperintense multinodular lesions in the deep cortex and superficial white matter of the frontal (n=1) or temporal lobes (n=4). Microscopically, the tumor cells were mostly arranged in discrete and coalescent nodules primarily within the deep cortical ribbon and superficial subcortical white matter. The tumors were composed of large cells with ganglionic morphology, vesicular nuclei, prominent nucleoli and amphophilic or lightly basophilic cytoplasm. They exhibited varying degrees of matrix vacuolization. Vacuolated tumor cells did not show overt cellular atypia or any mitotic activities. Immunohistochemically, tumor cells exhibited widespread nuclear staining for the HuC/HuD neuronal antigens, SOX10 and Olig2. Expression of other neuronal markers, including synaptophysin, neurofilament and MAP2, was patchy to absent. The tumor cells were negative for NeuN, GFAP, p53, H3K27M, IDH1 R132H, ATRX, BRG1, INI1 and BRAF V600E. No aberrant molecular changes were identified in case 3 and case 5 using next-generation sequencing (including 131 genes related to diagnosis and prognosis of central nervous system tumors). All patients underwent complete or substantial tumor excision without adjuvant chemoradiotherapy. Post-operative follow-up information over intervals of 6 months to 8 years was available for five patients. All patients were free of recurrence. Conclusions: MVNT is an indolent tumor, mostly affecting adults, which supports classifying MVNT as WHO grade 1. There is no tumor recurrence even in the patients treated with subtotal surgical excision. MVNTs may be considered for observation or non-surgical treatments if they are asymptomatic.

Salvia miltiorrhiza is one of the commonly used bulk medicinal materials, which has significant effect on cardiovascular disease, and are heavy demanded in Asia, Europe, North America, Russia and Africa. Consequently, increasing the yield and quality of S. miltiorrhiza has become a major concern worldwide. With the current wild resources of S. miltiorrhiza gradually decreasing, cultivated products occupy most of the markets. However, the cultivation area is widely distributed and the cultivation techniques is different, which lead to the quality and yield of S. miltiorrhiza in consistent. This paper combined visiting survey with document analysis to carry out the cultivation situation of S. miltiorrhiza in main cultivation areas of Shandong, Henan, Sichuan, Shanxi and Hebei provinces. There exist big differences of the ecological environment, mode of cultivation, fertilization, pest control, harvesting processing among the producing areas. We should carry on the ecological suitability zoning analysis and suitable cultivation of each area study to form a pattern of high quality and high yield for the sustainable development of S. miltiorrhiza cultivation.

Diabetes mellitus complicated with cerebral infarction is the commonest and most serious vascular complication of diabetes mellitus. With a high disability and mortality rate, it seriously threatens human health. Because the pathogenesis is still unclear, more and more scholars have focused on the research of diabetic cerebral infarction at home and abroad. Traditional Chinese medicine(TCM) compounds have a remarkable curative effect in the treatment of diabetic cerebral infarction. Its mechanisms of action mainly include anti-hypertension, reduction of blood sugar and lipid, promotion of vascular regeneration and vascular endothelial function, anticoagulation, anti-thrombosis, improvement of nerve function defect, reduction of infarct volume, improvement of hemorheological, inhibition of inflammation and platelet aggregation, and promotion of collateral circulation. Through literature search, this paper summarizes the research progress of the mechanisms of TCM compounds in treating diabetic cerebral infarction in recent five years at home and abroad, in order to provide reference for clinical treatment.

Objective: To investigate the current status and real performance of the detection of RUNX1-RUNX1T1 fusion transcript levels and WT1 transcript levels in China through interlaboratory comparison. Methods: Peking University People's Hospital (PKUPH) prepared the samples for comparison. That is, the fresh RUNX1-RUNX1T1 positive (+) bone morrow nucleated cells were serially diluted with RUNX1-RUNX1T1 negative (-) nucleated cells from different patients. Totally 23 sets with 14 different samples per set were prepared. TRIzol reagent was added in each tube and thoroughly mixed with cells for homogenization. Each laboratory simultaneously tested RUNX1-RUNX1T1 and WT1 transcript levels of one set of samples by real-time quantitative PCR method. All transcript levels were reported as the percentage of RUNX1-RUNX1T1 or WT1 transcript copies/ABL copies. Spearman correlation coefficient between the reported transcript levels of each participated laboratory and those of PKUPH was calculated. Results: ①RUNX1-RUNX1T1 comparison: 9 samples were (+) and 5 were (-) , the false negative and positive rates of the 20 participated laboratories were 0 (0/180) and 5% (5/100) , respectively. The reported transcript levels of all 9 positive samples were different among laboratories. The median reported transcript levels of 9 positive samples were from 0.060% to 176.7%, which covered 3.5-log. The ratios of each sample's highest to the lowest reported transcript levels were from 5.5 to 12.3 (one result which obviously deviated from other laboratories' results was not included) , 85% (17/20) of the laboratories had correlation coefficient ≥0.98. ②WT1 comparison: The median reported transcript levels of all 14 samples were from 0.17% to 67.6%, which covered 2.6-log. The ratios of each sample's highest to the lowest reported transcript levels were from 5.3-13.7, 62% (13/21) of the laboratories had correlation coefficient ≥0.98. ③ The relative relationship of the reported RUNX1-RUNX1T1 transcript levels between the participants and PKUPH was not always consistent with that of WT1 transcript levels. Both RUNX1-RUNX1T1 and WT1 transcript levels from 2 and 7 laboratories were individually lower than and higher than those of PKUPH, whereas for the rest 11 laboratories, one transcript level was higher than and the other was lower than that of PKUPH. Conclusion: The reported RUNX1-RUNX1T1 and WT1 transcript levels were different among laboratories for the same sample. Most of the participated laboratories reported highly consistent result with that of PKUPH. The relationship between laboratories of the different transcript levels may not be the same.

OBJECTIVEAcupuncture has a definite therapeutic effect on chronic obstructive pulmonary disease (COPD), and the cholinergic anti-inflammatory pathway (CAP) has been shown to be involved in regulation of inflammation. In this study, we investigated whether electro-acupuncture (EA) affects the CAP in COPD.

METHODSSprague-Dawley rats were induced into COPD through exposure to cigarette smoke combined with lipopolysaccharide. EA treatment was applied at Zusanli (ST36) and Feishu (BL13) points for 30 min/d for 7 d. Seventy-two rats were randomly divided into six study groups, including normal, normal + EA, normal + α-bungarotoxin (α-BGT) (the antagonist of the nicotinic acetylcholine receptor α7 subunit (α7nAChR)) + EA, COPD, COPD + EA, and COPD + α-BGT + EA. Lung function, pathology and vagus nerve discharge were tested. The levels of acetylcholine (ACh), acetylcholinesterase (AChE), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in bronchoalveolar lavage fluid (BALF) and lung tissue were measured by enzyme-linked immunosorbent assay. The mRNA and protein expression and immunoreactivity of α7nAChR and its postreceptor inflammation signal pathway, including janus kinase 2 (JAK2), signal transducers and activators of transcription 3 (STAT3), nuclear factor-κB (NF-κB), were observed by quantitative reverse transcription-polymerase chain reaction, Western blot and immunohistochemistry.

RESULTSCompared with normal rats, there were a significant decline in lung function and discharge of the vagus nerve (P < 0.01), a marked sign of lung inflammation and an increase of ACh, AChE, IL-6 and TNF-α level in BALF or lung tissue (P < 0.05, P < 0.01) and higher expression of α7nAChR, JAK2, STAT3 and NF-κB (P < 0.05, P < 0.01) in the COPD rats. In rats receiving EA, the lung function and vagal discharge were enhanced (P < 0.01), lung inflammation was improved and the levels of ACh, AChE, IL-6 and TNF-α were decreased (P < 0.01). Further, the expression of α7nAChR, JAK2, STAT3 and NF-κB was downregulated (P < 0.05, P < 0.01). However, the above effects of EA were blocked in rats injected with α-BGT (P < 0.01).

CONCLUSIONEA treatment can reduce the lung inflammatory response and improve lung function in COPD, which may be related to its involvement in the regulation of CAP.

Objective: To investigate the relationship between plasma level of pro-protein convertase subtilisin kexin type9 (PCSK9) and coronary artery calcification (CAC). Methods: A total of 380 consecutive chest pain patients without lipid-lowering therapy were enrolled. All patients received CT scan and coronary artery calcification (CAC) score measurement and were divided into 2 groups: CAC group, n=156 patients with CAC score>0 and Non-CAC group, n=224 patients with CAC score=0. CAC group was further classified in 3 subgroups as CAC score (1-100) subgroup, n=53, CAC score (101-400) subgroup, n=64 and CAC score>400 subgroup, n=39. Clinical data was collected, plasma levels of PCSK9 were measured in all patients and the relationship between PCSK9 and CAC score was investigated. Results: Plasma PCSK9 level in CAC group was higher than Non-CAC group (260.23±69.34) ng/ml vs (205.46±53.21) ng/ml, P<0.001; alone with CAC score increasing, PCSK9 level was elevating accordingly as in CAC score (1-100) subgroup, CAC score (101-400) subgroup and CAC score>400 subgroup, PCSK9 levels were (247.38±72.68) ng/ml, (264.87±57.63) ng/ml and (295.33±69.06) ng/ml respectively, all P<0.05. With adjusted traditional cardiovascular risk factors, multivariate regression analysis confirmed that plasma PCSK9 level was independently related to CAC score (β=0.584, P=0.002). In addition, the optimal cut-off value for PCSK9 predicting CAC was 228.58 ng/ml with sensitivity at 67% and specificity at 71%. Conclusion: Plasma PCSK9 level was related to CAC in chest pain patients without lipid-lowering therapy.
