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 study the effects of Yishen daluo decoction on inflammatory factors and cyclic adenosine monophosphate（cAMP）/protein kinase A （PKA）/cAMP response element binding protein （CREB） signal pathway in experimental autoimmune encephalomyelitis （EAE） model mice by inhibiting the expressions of β-arrestin1， and to explore the mechanism of Yishen daluo decoction in the treatment of EAE. METHODS Sixty mice were randomly divided into normal group， model group， TCM group （Yishen daluo decoction 20 g/kg）， positive control group （prednisone acetate 3.9 mg/kg）， β-arrestin1 siRNA adeno- associated virus （AAV-β） group， AAV-β+TCM group， with 10 mice in each group. Except for normal group， EAE model was made in other groups. AAV-β group and AAV-β+TCM group were injected with AAV-β via tail vein to interfere with the expression of β -arrestin1 protein. Starting from the 8th day of modeling， they were given corresponding drug solution/normal saline intragastrically， once a day， for consecutive 14 days. The neurological function score of mice was detected； the pathological and morphological changes were observed in the brain and spinal cord tissues of mice； the serum levels of inflammatory factors [interleukin-2 （IL-2）， IL-23， interferon-γ （IFN-γ）] in mice were determined； the expressions of β-arrestin1， cAMP， PKA and CREB in brain and spinal cord were detected. RESULTS Compared with normal group， neurological function scores， serum levels of inflammatory factors， and protein expressions of β-arrestin1 in brain and spinal cord were significantly increased （P＜0.05 or P＜ 0.01）； protein expressions of PKA， CREB and cAMP in brain and spinal cord were decreased significantly（P＜0.05 or P＜0.01）. The deep staining of cellular shrinkage and aggregation of inflammatory cells were observed in most neurons of the brain and spinal cord， with varying degrees of demyelinating. Compared with model group， the neurological function scores， pathological changes in brain and spinal cord tissues， and most indicators （except for CREB and cAMP proteins in the brain tissue of AAV-β group） were significantly reversed （P＜0.05 or P＜0.01）.Compared with AAV- β group， the neurological function scores， the levels of IFN-γ in serum and β-arrestin1 in spinal cord were significantly decreased （P＜0.05 or P＜0.01）， PKA and cAMP in brain and spinal cord tissues were significantly increased in AAV- β +TCM group （P＜0.05 or P＜0.01）. CONCLUSIONS Yishen daluo decoction can inhibit the expression of β-arrestin1 in the central nervous system thus activating the cAMP/PKA/CREB signaling pathway， relieving nervous system inflammation， and ultimately alleviates the symptoms of EAE.

Objective:To analyze the lifestyle for brain health related factors and demographic characteristics through machine learning to achieve the assessing effect of mild cognitive impairement prevalence risk among rural elderly people in Guizhou.Methods:From July to August 2019, a multi-stage cluster random sampling method was used to select 1 235 rural elderly people aged 60 years and above in Guizhou Province as the subjects, and the investigation was performed with questionnaire and physical examination.The Mini-Mental State Examination (MMSE) was used to assess cognitive function, and the important features and optimal number of features based on 12 LIBRA factors and 4 demographic characteristics were selected.Logistic regression and random forest algorithm were used to establish a evaluation model for the risk of mild cognitive impairment in the elderly.The evaluation efficacy of the model was also assessed using a combination of precision, accuracy, sensitivity, specificity, F1 score and area under curve (AUC) of receiver operating characteristic curve, and the Delong method was used to check the difference of AUC values between the two models.Results:A total of 291 subjects were diagnosed with mild cognitive impairment, with a detection rate of 23.56% (291/1 235). The AUC values of logistic regression and random forest models evaluating the risk of mild cognitive impairment in the rural elderly were 0.758 and 0.820, respectively, and the differences were statistically significant(both P<0.05). The random forest model had better evaluations with an accuracy of 0.823, precision of 0.805, sensitivity of 0.874, specificity of 0.767 and F1 score of 0.838, all of which were better than those of the logistic regression model.And the random forest model was also more stable after 10-fold cross-validation. Conclusion:The lifestyle for brain health related factors combined with demographic characteristics can more accurately evaluate the risk of mild cognitive impairment among rural elderly people in Guizhou.The random forest model is better than the logistic regression model.

Objective:To explore the effect of intelligent voice follow-up system in elderly patients with diabetes.Methods:From March 2021 to June 2022, 182 patients with type 2 diabetes hospitalized in the Healthcare Center of Beijing Friendship Hospital Affiliated to Capital Medical University were selected by convenience sampling. The patients were randomly divided into a control group and an observation group, with 91 cases in each group. The control group implemented routine follow-up management, while the observation group implemented follow-up management based on an intelligent voice follow-up system. The medication compliance, diet behavior compliance, fasting blood glucose and glycated hemoglobin were compared between the two groups.Results:After intervention, 49 cases (53.85%) in the observation group fully complied with medication, 32 cases (35.16%) partially complied, and 10 cases (10.99%) did not comply. In the control group, 35 cases (38.46%) fully complied with medication, 34 cases (37.36%) partially complied, and 22 cases (24.18%) did not comply. The medication compliance of the observation group was better than that of the control group, with a statistically significant difference ( Z=2.502, P<0.05). The medication compliance of the observation group after intervention was better than before intervention, with a statistically significant difference ( Z=3.293, P<0.05). After intervention, the scores of all dimensions and total scores of the Dietary Behavior Compliance Scale in the observation group were higher than those in the control group and before intervention, with statistically significant differences ( P<0.05). After the intervention, the fasting blood glucose and glycated hemoglobin in the observation group were lower than those in the control group and before the intervention, and the difference was statistically significant ( P<0.05) . Conclusions:The intelligent voice follow-up system can effectively improve the medication compliance and diet compliance of elderly diabetes patients, and improve the blood glucose control, which is worthy of clinical practice.

Objective:To investigate the correlation between serum ceruloplasmin level and elevated impulsivity in elderly patients with Parkinson′s disease (PD).Methods:227 elderly PD patients treated in Jinhua People′s Hospital from October 2019 to June 2021 were selected as the research objects. They were grouped according to the 75th percentile of serum ceruloplasmin. 0-75th percentile was defined as normal and >75th percentile was defined as high level. The differences of second-order and first-order factor scores of Barratt′s Impulsivity Scale Version 11 (BIS-11) between the two groups were observed. After balancing the general characteristics, the third part of Parkinson′s Disease Rating Scale (MDS-UPDRS), Hoehn&Yahr Scale, Addenbrooke Cognitive Examination Revised Edition (ACE-R), clinical treatment plan and other data, the correlation between ceruloplasmin and BIS-11 was observed.Results:According to the 75th percentile level of ceruloplasmin, 56 patients were included in the high-level group and 171 patients were included in the normal group. The level of ceruloplasmin, the ratio of female patients, MDS-UPDRS Ⅲ, Hoehn&Yahr Scale and ACE-R score in the high-level group were significantly higher than those in the normal group (all P<0.05). The second-order unplanned and corresponding first-order self-control and first-order self-knowledge complexity in the high-level group were higher than those in the normal group (all P<0.05). There was no significant difference in second-order attention, first-order attention, first-order cognitive instability, second-order motivation, first-order motivation, first-order stability and BIS-11 score between the two groups (all P>0.05). After removing the confounding factors by multifactor logistic analysis, ceruloplasmin was correlated with second-order unplanned and its corresponding first-order factors (self-control and self-knowledge complexity) (all P<0.05). Conclusions:The serum ceruloplasmin level in elderly PD patients is related to the elevated level of BIS-11 unplanned impulse.

In order to explore the treatment of Her-2 positive breast cancer patients who failed in multi-line treatments, we retrospectively analyzed the clinical data of a patient with refractory Her-2 positive breast cancer.The patient was initially diagnosed as Her-2 positive advanced breast cancer.After six line treatment in the outer hospital, the patient′s condition was basically in a progressive state.The breast tumor was broken and purulent, the lung metastasis increased, and the patient′s quality of life was poor.The patient was admitted to Department of Breast Surgery of Affiliated Suqian Hospital of Xuzhou Medical University, after MDT discussion, we gave pyrrolotinib combined with capecitabine treatment, the chest wound healed gradually, the lung metastasis gradually reduced, and the quality of life was better.A retrospective analysis of this case showed that pyrrolidine combined with capecitabine may bring hope to Her-2 positive breast cancer patients who failed to receive multi-line therapies, especially those who failed to target therapy.

BACKGROUND: Cardiovascular (CV) disease is the leading cause of morbidity and mortality in adults with type 2 diabetes (T2D). The aim of this study was to determine the CV risk in Chinese patients with T2D based on the 2019 European Society of Cardiology (ESC) and the European Association for the Study of Diabetes (EASD) guidelines on diabetes, pre-diabetes, and CV diseases. METHODS: A total of 25,411 patients with T2D, who participated in the study of China Cardiometabolic Registries 3B study, were included in our analysis. We assessed the proportions of patients in each CV risk category according to 2019 ESC/EASD guidelines. RESULTS: Based on the 2019 ESC/EASD guidelines, 16,663 (65.6%), 1895 (7.5%), and 152 (0.6%) of patients were included in "very high risk," "high risk," and "moderate risk" categories, respectively. The proportions of patients in each category varied based on age, sex, body mass index, and duration. While 58.7% (9786/16,663) of elderly patients were classified to "very high risk" group, 89.6% (3732/4165) of patients with obesity were divided into "very high risk" group. Almost all patients with a duration of diabetes >10 years had "very high risk" or "high risk." However, 6701 (26.4%) of Chinese T2D patients, who had shorter duration, and one or two risk factors, could not be included in any category (the "unclear risk" category). CONCLUSIONS In China, most patients with T2D have "very high" or "high" CV risk based on 2019 ESC/EASD guidelines. However, the risk of patients in "unclear risk" group needs to be further classified.
